Disclosure of Invention

However, the pet diapers of patent documents 1 and 2 have the following problems.

When wearing a pet diaper, the pet diaper is not only in a state where the pet to be worn is stationary, but may not be worn at an appropriate position due to the activity of the pet. Further, the pet diaper may not be worn at a proper position depending on the pet and the season, and the size of the waist, etc. may vary. Even if the pet diaper is worn at a position shifted from the proper position, the trouble cannot be recognized by the reaction of the pet, and the pet diaper may not be changed to the proper position.

Generally, a pet diaper does not have an absorbent core arranged to cover the entire circumference of the waist of a pet, but has an absorbent core arranged only in a region where excrement is absorbed, that is, a part of the waist. Therefore, if the pet diaper is not worn at an appropriate position, leakage of excrement may occur.

Accordingly, an object of the present invention is to provide a pet diaper which can be worn at an appropriate position and can suppress leakage of excrement.

The pet diaper includes a main body having a front sheet, a back sheet, and an absorbent core disposed between the front sheet and the back sheet, and a joining section joining a surface of the main body on the back sheet side to a surface of the main body on the front sheet side. The absorbent core is disposed inside the body portion in the girth direction relative to both end edges of the body portion, and the pet diaper includes a mark portion for guiding a wearing position of the pet diaper.

Detailed Description

(1) Brief description of the embodiments

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.

The pet diaper includes a main body having a front sheet, a back sheet, and an absorbent core disposed between the front sheet and the back sheet, and a joining section joining a surface of the main body on the back sheet side to a surface of the main body on the front sheet side. The absorbent core is disposed inside the body portion in the girth direction relative to both end edges of the body portion, and the pet diaper includes a mark portion for guiding a wearing position of the pet diaper. According to this aspect, the user can align the diaper for pet based on the mark portion. Therefore, the diaper for pet can be worn at a suitable position. Even when the diaper is not worn at a proper position or is displaced when worn, the diaper can be changed to a proper position or a proper state based on the displacement of the mark portion and the distortion of the diaper. Therefore, in the pet diaper having the absorbent core shorter than the main body in the girth direction, the absorbent core can be disposed at an appropriate position where it can absorb excrement, and leakage of excrement can be suppressed.

According to a preferred embodiment, the marking portion may be configured to be visually recognizable from the topsheet side of the pet diaper. The topsheet side of the pet diaper is a side that comes into contact with a pet when worn. The user can bring the mark part into contact with the body and align the pet diaper.

According to a preferred embodiment, the marking portion may be configured to be visually recognizable from the back sheet side of the pet diaper. The back sheet side of the pet diaper is positioned outside when worn, and can be visually confirmed even after the diaper is brought into contact with a pet. Therefore, the alignment can be performed not only during the wearing operation but also after the wearing operation. Even when the diaper is rotated in the girth direction and displaced when worn, the displacement of the position can be grasped based on the mark portions, and the position can be changed to an appropriate position.

According to a preferred aspect, the mark portion may have a waist center mark portion that marks the center of the absorbent core in the waist direction. According to this aspect, in the pet diaper having a relatively short waist, the absorbent core can be disposed at a position where it can absorb excrement, and leakage of excrement can be suppressed.

According to a preferred embodiment, the plurality of markers may be arranged at intervals in the girth direction. According to this aspect, since the plurality of marking portions are arranged along the girth direction, the positioning can be performed based on the marking portions in various directions (for example, in the case of visual confirmation from the right side, in the case of visual confirmation from the left side). Further, the state can be changed to an appropriate state by grasping the right-side offset, the skew, and the left-side offset, the skew, and the like in various directions.

According to a preferred aspect, the mark portion may include a pair of waist-side mark portions disposed on both sides across the center of the absorbent core in the waist-circumferential direction. According to this aspect, the user can easily grasp the position of the absorbent core in the waist-circumferential direction by the waist-side mark portions arranged on both sides with respect to the center of the absorbent core in the waist-circumferential direction. Therefore, it is possible to appropriately arrange the absorbent core in the girth direction and suppress leakage of excrement.

According to a preferred aspect, one of the pair of waist-side mark portions may be disposed in a region overlapping one end portion in the waist direction of the absorbent core, and the other of the pair of waist-side mark portions may be disposed in a region overlapping the other end portion in the waist direction of the absorbent core. According to this aspect, the user can grasp the positions of both ends of the absorbent core in the girth direction, and can dispose the absorbent core so as not to cause leakage.

According to a preferred aspect, one of the pair of waist-side mark portions may be disposed outward in the waist-surrounding direction than one end edge of the absorbent core in the waist-surrounding direction, and the other of the pair of waist-side mark portions may be disposed outward in the waist-surrounding direction than the other end edge of the absorbent core in the waist-surrounding direction. According to this aspect, the user can grasp the position of the region where the absorbent core is not disposed by the mark portion disposed on the outer side in the girth direction, and can dispose the absorbent core so as not to cause leakage.

According to a preferred aspect, a stretchable member that stretches in at least one of the girth direction and the crossing direction may be disposed in the main body, and the marker may have a stretchable marker disposed in a region overlapping with the stretchable member. According to this aspect, the stretchable member is stretched in at least one of the girth direction and the crossing direction, and is worn so as to be in close contact with the body of the pet. Since the marker portion is disposed in the region overlapping with the stretchable member, the user can grasp the position of the stretchable member in close contact with the body, and can dispose the stretchable member at an appropriate position.

According to a preferred embodiment, the absorbent core may be disposed inside the main body in the crossing direction with respect to both end edges of the main body, and the mark portion may include a crossing center mark portion that marks the center of the absorbent core in the crossing direction. According to this aspect, in the pet diaper having a short absorbent core in the cross direction, the absorbent core can be disposed at a position where it can absorb excrement, and leakage of excrement can be suppressed.

According to a preferred aspect, the plurality of marking portions may be arranged at intervals in the intersecting direction. According to this aspect, since the plurality of marking portions are arranged along the intersecting direction, the user can perform positioning based on the marking portions in various directions (for example, in the case of visual confirmation from the front side, in the case of visual confirmation from the rear side).

According to a preferable mode, the mark portion may have a pair of crossing side mark portions disposed on both sides across the center of the absorbent core in the crossing direction. According to this aspect, the user can easily grasp the position of the absorbent core in the intersecting direction by the intersecting side mark portions disposed on both sides of the center of the absorbent core in the intersecting direction. Therefore, it is possible to appropriately arrange the absorbent core in the crossing direction and suppress leakage of excrement.

According to a preferred aspect, one of the pair of cross-side mark portions may be disposed in a region overlapping one end portion of the absorbent core in the cross direction, and the other of the pair of cross-side mark portions may be disposed in a region overlapping the other end portion of the absorbent core in the cross direction. According to this aspect, the user can grasp the positions of both end portions in the cross direction of the absorbent core, and can arrange the absorbent core so as not to cause leakage.

According to a preferred aspect, one of the pair of cross side mark portions may be disposed outside in the cross direction with respect to one end edge of the absorbent core in the cross direction, and the other of the pair of cross side mark portions may be disposed outside in the cross direction with respect to the other end edge of the absorbent core in the cross direction. According to this aspect, the user can grasp the position of the region where the absorbent core is not disposed, and can dispose the absorbent core so as not to cause leakage.

According to a preferred embodiment, the back sheet may be printed with a first decorative portion and a second decorative portion having a design different from the first decorative portion, and the mark portion may include a boundary mark portion formed by a boundary between the first decorative portion and the second decorative portion. According to the present invention, the decoration performance can be improved by the two designs of the first decoration part and the second decoration part, and the alignment can be performed by the mark part.

According to a preferable mode, the mark portion may have an end edge mark portion that marks an outer end edge of the main body portion in the crossing direction. According to this aspect, the outer edge of the main body in the cross direction can be appropriately disposed, the entire main body can be worn in an appropriate wound form, the fit can be improved, and the uncomfortable feeling due to excessive tightening can be reduced.

A pet diaper according to another aspect of the present invention includes a girth direction arranged along a girth direction of a pet and a cross direction orthogonal to the girth direction, the pet diaper includes a main body portion including a front sheet, a back sheet, and an absorbent core arranged between the front sheet and the back sheet, and a joint portion provided at a body 1 st end portion, which is one end portion in the girth direction of the main body portion, and joining the body 1 st end portion and a body 2 nd end portion, which is the other end portion in the girth direction of the main body portion. The main body portion has an indicator disposed between the back sheet and the absorbent core, and changes color by contact with moisture. The indicator extends along the waist-circumference direction. The length of the indicator in the girth direction is 50% or more of the length of a product region extending between an end edge of the main body 2 nd end portion side of the main body and the joint portion. In a diaper wound around the waist of a pet, an indicator is disposed along the waist direction. The body fluid is discharged at the abdomen. The response is indicated in the abdomen. However, in a state where the pet stands while crawling on the four legs, it is difficult for the user (owner) to visually confirm the abdomen, and the color reaction of the indicator may not be confirmed. However, the indicator mark is disposed in 50% or more of the product area, and 50% or more of the girth direction in a state where the pet diaper is loosely wound. Therefore, in the worn state, the indicator is disposed not only on the abdomen but also on the side of the pet, and the user can easily visually confirm the indicator when wearing the pet.

According to a preferred aspect, the body portion has a region obtained by quartering the product region in the girth direction. The quartered region has a 1 st product region located closest to the 1 st end side of the main body and a 2 nd product region located closest to the 2 nd end side of the main body. The indicator is disposed in at least one of the 1 st product area and the 2 nd product area. The 1 st product region and the 2 nd product region are easily arranged on the side and back of the pet when worn. By disposing the indicator in this region, the visibility of the indicator when worn can be further improved. Further, since the indicator mark extends to the end portion side in the girth direction of the body section, the spreading of urine in the girth direction can be easily visually recognized, and leakage of body fluid can be suppressed.

According to a preferred version, the indicator is disposed in both the 1 st product area and the 2 nd product area. In the case of leg lifting for urination, urine readily spreads to product 1 or product 2 areas under the influence of gravity. Since it is different for the dog which leg is often lifted, leakage prevention can be achieved by the arrangement on both sides.

According to a preferred aspect, the length of the indicator in the waist circumferential direction is 50% or more of the length of the absorbent core. In a diaper wound around a pet in the girth direction, the region where the absorbent core is disposed is difficult to visually confirm when worn. When body fluid spreads to a portion where the absorbent core is absent, there is a possibility of causing the hair of the back to be wet. When the amount of the liquid is more than 50% of the amount of the liquid, the timing of replacement can be visually confirmed, and the hair can be prevented from wetting or leaking.

According to a preferred aspect, the length of the indicator in the waist circumferential direction is 80% or more of the length of the absorbent core. According to this aspect, the state in which the body fluid diffuses to the end edge in the girth direction of the absorbent core can be grasped more appropriately.

A diaper for pet of another aspect has a girth direction arranged along a girth direction of a pet and a crossing direction orthogonal to the girth direction and extending in a direction connecting a back side of the pet from a belly side thereof, the diaper for pet has a main body portion having a front sheet, a back sheet, and an absorbent core arranged between the front sheet and the back sheet, and a tail hole portion through which a tail of the pet can pass. The main body portion has an indicator disposed between the back sheet and the absorbent core, and changes color by contact with moisture. The indicator extends along the crossing direction. Having a separation region separating the absorbent core and the tail hole portion in the cross direction. The indicator is disposed across the core region and the separation region overlapping the absorbent core. If the body fluid reaches the tail hole portion, the body fluid may leak through the tail hole portion. However, since the indicator is disposed so as to straddle the core region and the partition region, the spreading of the body fluid over the absorbent core can be detected, and leakage of the body fluid can be suppressed.

According to a preferable mode, the indication mark is disposed in 50% or more of the divided region in the crossing direction. According to this aspect, the state of diffusion of the body fluid in the partition region can be grasped more appropriately by the indicator.

According to a preferred aspect, the indicator is disposed so as to span a hole portion region overlapping with the tail hole portion and the partition region. According to this aspect, it is possible to detect that the body fluid has reached the region overlapping the tail hole portion, and to suppress leakage of the body fluid through the tail hole portion.

According to a preferred embodiment, the back sheet has a printed area on which the printing is performed and a non-printed area on which the printing is not performed. 50% or more of the area of the indicator is disposed in a region overlapping the non-printing region. According to this aspect, 50% or more of the area of the indication mark overlaps the non-printed region, and is less likely to be affected by printing on the back sheet. Therefore, the visibility of the indicator can be improved.

According to a preferred embodiment, the indicator is disposed across a boundary between the non-printing region and the printing region. The indication mark has different visual confirmability between the print area and the non-print area. By locally differentiating the appearance of the indicator, it is easy to grasp the form of the color reaction of the indicator, that is, the portion to which the body fluid has diffused.

The method for manufacturing a diaper for pets according to the embodiment comprises: a sheet conveying step of conveying a continuous sheet body obtained by continuously conveying sheets; a marking step of applying a marking portion to the continuous sheet body; and a core lamination step of laminating an absorbent core with respect to the continuous sheet body having the mark portion, wherein in the core lamination step, a position of the mark portion of the continuous sheet body is detected, and a lamination position of the absorbent core is adjusted based on the position of the mark portion. According to this aspect, the relative position of the mark portion and the absorbent core can be kept constant. Therefore, when the diaper is worn with the mark portion as a reference, the wearing position of the absorbent core can be prevented from shifting for each diaper. The accuracy of positioning by the marking portion can be improved by suppressing the positional deviation of the marking portion in the entire diaper.

(2) Structure of diaper for pet

Hereinafter, a pet diaper according to an embodiment will be described with reference to the drawings. In the following description of the drawings, the same or similar reference numerals are given to the same or similar parts. However, the drawings are schematic, and it should be noted that the scale of each dimension and the like are different from those in reality. Therefore, specific dimensions and the like should be determined with reference to the following description. In addition, the drawings may include portions having different dimensional relationships and ratios from each other.

In the present specification, "pet" broadly includes vertebrates, invertebrates, and typically includes pets such as cats, dogs, rabbits, hamsters, and the like. The pet diaper of the present embodiment is a diaper for dogs. In the modification, a diaper for cats may be used.

Fig. 1 is a plan view of the pet diaper of the first embodiment as viewed from the skin surface side. Fig. 2 is a plan view of the pet diaper of the first embodiment, as viewed from the non-skin surface side. Fig. 3 is a schematic sectional view of the diaper for pet taken along line a-a shown in fig. 1. Fig. 1 and 2 show an extended state in which the pet diaper 1 is extended to a state in which no wrinkles are formed. In the cross-sectional view shown in fig. 3, the members are shown separately in the thickness direction T for the convenience of explanation, but in an actual product, they are in contact with each other in the thickness direction T. Fig. 4 is a view schematically showing a wearing state of the pet diaper.

The diaper for pet comprises: the pet diaper comprises a waistline direction W arranged along the waistline direction of the pet, a cross direction Z orthogonal to the waistline direction W, and a thickness direction T orthogonal to the waistline direction W and the cross direction Z. The crossing direction Z extends in the longitudinal direction of the pet, i.e. the direction from the crotch side to the side remote from the crotch. The thickness direction T extends toward a front surface side T1 which comes into contact with a pet in a wearing state and toward an outer rear surface side T2 in the wearing state. As shown in fig. 4, the pet diaper according to the first embodiment is not arranged so as to cover the abdomen of a pet from the crotch to the back, but is worn so as to be wrapped around the waist. Therefore, the length of the pet diaper 1 in the girth direction W is longer than the length of the pet diaper 1 in the cross direction Z.

The pet diaper 1 has a main body 2 and a joint 40. The main body 2 has at least a front sheet 10, a back sheet 20, and an absorbent core 30. The surface sheet 10 is disposed on the surface that comes into contact with the pet. The topsheet 10 has liquid permeability for allowing body fluid to pass through to the absorbent core 30 side. The topsheet 10 may have a central sheet 11 positioned at the center in the cross direction Z and covering the absorbent core 30 and side sheets 12 covering both side portions in the cross direction Z of the central sheet 11. The surface sheet 10 may be provided with a printed portion. The printing portion may constitute a marking portion 50 described later.

As shown in fig. 3, the side panels 12 may be folded. Specifically, the side sheet 12 on one end side (left side in fig. 1) in the intersecting direction Z is folded back toward the outer surface side T2 at the inner edge of the side sheet 12. Further, the side sheet 12 on the other end side (right side in fig. 1) in the intersecting direction Z is folded back to the surface side T1 at the inner edge of the side sheet 12, and the folded-back portion is folded back to the surface side T1. The side stretchable members 13 in a state of being stretched in the girth direction W may be disposed between the folded side sheets 12. The side stretchable member 13 may constitute leak-proof gathers standing toward the pet side. In addition, one end portion side in the intersecting direction Z may be disposed on the front side of the pet in the worn state, and the other end portion side in the intersecting direction Z may be disposed on the rear side of the pet in the worn state. The side sheet on the one end side in the intersecting direction Z and the side sheet on the other end side in the intersecting direction Z are asymmetric in the present embodiment, but may be symmetric in a modification. The end portion in the present invention is a portion occupying a certain range including the edge.

The absorbent core 30 is disposed between the top sheet 10 and the back sheet 20. The absorbent core 30 is laminated with an absorbent material such as pulp. A core covering sheet 32 may be provided to cover the absorbent core 30. The absorbent core 30 is disposed inward of both end edges 2WE of the main body 2 in the girth direction W. That is, the length of the absorbent core 30 in the girth direction W is shorter than the length of the body 2 in the girth direction W. The absorbent core 30 is disposed in the center of the body 2 in the girth direction W, but not in the outer side of the body 2 in the girth direction W. The absorbent core 30 may be disposed inside the opposite end edges 2ZE of the main body 2 in the cross direction Z. That is, the length of the absorbent core 30 in the cross direction Z may be shorter than the length of the main body 2 in the cross direction Z. The absorbent core 30 may be disposed in the center of the main body 2 in the cross direction Z, but not in the outer side of the main body 2 in the cross direction Z. Further, the absorbent core and the core covering sheet may be provided with a printed portion. The printed portion may constitute the marking portion 50.

The back sheet 20 may have a liquid-impermeable back surface film 21 and a back surface nonwoven fabric 22 on the outer surface side of the back surface film 21. In the modified example, the back sheet may have a liquid-impermeable back surface film and a back surface nonwoven fabric on the back surface side of the back surface film 21. An indicator for indicating a color reaction by contact with a body fluid and a printed portion may be provided on the surface of the front surface side T1 of the back film 21, and a printed portion may be provided on the surface of the outer surface side T2 of the back film 21. At least one of the indication mark and the printing portion may constitute the marking portion 50. The length of the back surface film 21 in the cross direction Z may be shorter than the length of the back surface nonwoven fabric 22 in the cross direction Z. That is, the back surface nonwoven fabric 22 may extend on both sides in the cross direction Z with respect to the back surface film 21. In the embodiment in which the printing portion is provided on the entire back surface film 21, the region where the back surface film 21 is disposed constitutes the printing region R1, and the non-printing region R2 in which printing is not performed may be provided on both sides in the cross direction Z with respect to the back surface film 21.

Waist gathers which expand and contract in the waist circumferential direction W may be disposed at both ends of the main body 2 in the cross direction Z. The waist gather may be located outside the absorbent core 30 in the cross direction Z and may be composed of the topsheet 10, the backsheet 20, and the waist stretchable member 25. The waist stretchable member 25 may be disposed between the front sheet 10 and the back sheet 20, and may be fixed to the front sheet 10 and the back sheet 20 in a state of being stretched in the waist direction W. The waist stretchable member 25 and the side stretchable members 13 constitute the stretchable member of the present invention.

The joint portions 40 join the main body portions 2 facing each other in a worn state. Specifically, the joining member is used to fix the outer surface 2Q, which is the surface on the back sheet side of the main body 2, to the inner surface 2P, which is the surface on the front sheet 10 side of the main body 2. The joint 40 of the present embodiment is a mechanical fastener disposed on the outer surface of the main body 2. The joining portion 40 is configured to be engageable with the front sheet 10 of the main body. The joint 40 is provided at one end in the girth direction W of the body 2. When the pet diaper 1 is worn on a pet, the joint 40 is engaged with the topsheet 10 by being disposed so as to cover the joint 40 with the other end portion in the girth direction of the body 2, whereby the wearing state of the pet diaper can be maintained. In the modified example, the joining portion may be disposed on the inner surface of the main body portion and may be configured as a back sheet that can be locked to the main body portion.

Next, the marker 50 will be described. The marking portion 50 guides the wearing position of the pet diaper 1. The size of the pet varies depending on the type of the pet, and the pet size varies due to the loss of hair depending on the season. Therefore, the user may have difficulty wearing the pet in a state of conforming to the shape of the body of the pet. However, according to the present embodiment, the pet diaper 1 can be aligned based on the marking portion 50. Therefore, the pet diaper 1 can be worn at a suitable position. Even when the diaper is not worn at a proper position or is displaced when worn, the position can be grasped based on the mark portion 50 and the diaper can be twisted, and the diaper can be changed to a proper position and a proper state.

Specifically, as shown in fig. 4, the pet diaper 1 is worn by wrapping the pet diaper 1 around the waist of the pet with the waist circumference direction W of the body 2 along the waist circumference of the pet. In this case, the absorbent core 30 is not disposed over the entire waistline W of the body 2, but is not disposed on both sides of the body 2 in the waistline direction. For example, when the body 2 is worn so that the outer portion in the girth direction W (the portion where the absorbent core is not disposed) faces the excretory opening of the pet, the absorbent core cannot absorb body fluid and leakage occurs. However, the absorbent core 30 may be disposed at an appropriate position where it can absorb excrement based on the mark portion 50, and leakage of excrement may be suppressed.

The marker 50 of the present embodiment may have a first marker 51 shown in fig. 1 and a second marker 52 shown in fig. 2. The first marker 51 is configured to be visually recognizable from the front sheet side (inner surface side) of the pet diaper. The topsheet side of the pet diaper is a side that comes into contact with a pet when worn. The first marker 51 can be positioned by bringing the first marker 51 into contact with the body.

The first mark portion 51 may be a printed portion provided on the top sheet 10, a printed portion provided on the absorbent core 30 or the core covering sheet 32, or a printed portion or an indication mark provided on the back sheet 20 and configured to be visually recognizable through the low basis weight portion of the absorbent core 30. The low basis weight portion is a portion where the basis weight of the absorbent material is lower than that of the surrounding portions or a portion where the basis weight of the absorbent material is 0.

The second marking portion 52 is configured to be visually recognizable from the back sheet side (outer surface side) of the pet diaper 1. The back sheet side of the pet diaper is positioned outside when worn, and can be visually confirmed even after the diaper is brought into contact with a pet, so that the positioning can be performed not only during the wearing operation but also after the wearing operation. Even when the diaper is rotated in the girth direction and displaced when worn, the displacement of the position can be grasped based on the mark portions, and the position can be changed to an appropriate position.

The second mark 52 may be a printed portion provided on the back sheet 20, or may be an indicator provided on the back sheet 20 or the core covering sheet 32. The back surface film 21 of the present embodiment is provided with a printing portion over the entire outer surface. The printed portion may constitute the marking portion and constitute the decorative portion. As shown in fig. 2 and 3, a printing portion constituting the second marking portion 52 and a printing portion constituting the decorative portion 59 are provided on the outer surface side surface of the back surface film of the present embodiment. The decoration portion is a portion having a design other than the marking portion, and includes not only a design having a pattern or a pattern but also a background color made of only colors.

In the present invention, "visually identifiable" means that: the device is capable of being visually confirmed when a subject having good vision (1.0 or more) in both eyes is observed in a room (reference: 500 to 750lx (lux)) brightly illuminated with daytime white (color temperature reference 4600 to 5400K (Kelvin)) at a distance of about 30 to 50 cm. Note that the marker 50 may have at least one of the first marker 51 and the second marker 52.

As shown in fig. 2, the second markers 52 may have a waist-center marker 50WC that indicates the center 30WC of the absorbent core 30 in the waist-circumferential direction W. The center of the absorbent core in the girth direction W may be aligned with respect to the excretory opening of the pet. Therefore, in the diaper for pet having the absorbent core 30 short in the girth direction, the absorbent core can be disposed at a position where it can absorb excrement, and leakage of excrement can be suppressed. The waist center mark 50WC of the present embodiment passes through the center 30WC of the absorbent core 30 in the waist direction W and extends over the entire area of the absorbent core 30 in the cross direction Z. The center 30WC of the absorbent core 30 in the girth direction W can be shown over the entire region of the absorbent core 30 in the cross direction Z, and the user can easily grasp the center position of the absorbent core 30. The waist center mark 50WC may be a dot or a pattern provided at the center 30WC of the absorbent core 30 in the waist circumferential direction W as long as it is arranged at the center 30WC of the absorbent core 30 in the waist circumferential direction W.

In addition, the second marker portion 52 may have a crossing center marker portion 50ZC that identifies the center 30ZC of the absorbent core 30 in the crossing direction Z. In the pet diaper having a short absorbent core 30 in the cross direction Z, the absorbent core 30 can be disposed at a position where it can absorb excrement, and leakage of excrement can be suppressed. The crossing center mark portion 50ZC may be a line extending in the girth direction W through the center 30ZC of the absorbent core 30 in the crossing direction Z, or may be a dot or a pattern disposed at the center 30ZC of the absorbent core 30 in the crossing direction Z. The waist center mark 50WC and the crossing center mark 50ZC may be formed of an indication mark indicating absorption of a body fluid by the absorbent core in a region overlapping the absorbent core 30.

As shown in fig. 1, a plurality of first mark portions 51 may be arranged at intervals in the girth direction W. Since the plurality of first mark portions 51 are arranged along the girth direction W, the positioning can be performed based on the first mark portions 51 in various directions (for example, in the case of visual confirmation from the right side or in the case of visual confirmation from the left side). Further, the state can be changed to an appropriate state by grasping the right-side offset, the skew, and the left-side offset, the skew, and the like in various directions. In the form in which the first mark portions 51 are spaced apart in the girth direction W, the position of the diaper can be aligned with the body of the pet with reference to the upper surface (the apex of the back), the lower surface (the apex of the bulge of the abdomen), the left side surface (between the upper surface and the lower surface on the left side in front view), and the right side surface (between the upper surface and the lower surface on the right side in front view) of the four-legged reptile pet as viewed from the front.

The first mark 51 may include a center mark 513, a first waist mark 511, and a second waist mark 512. The center mark 513 and the waist mark 511 and 512 may be disposed at intervals in the waist direction W. The center mark 513 constitutes a waist center mark 50WC located at the center 30WC of the absorbent core 30 in the waist circumferential direction W. The first waistline marker 511 and the second waistline marker 512 are disposed on both sides across the center of the absorbent core 30 in the waistline direction W, and constitute a pair of waistline markers of the present invention. The pair of waist-side mark portions are disposed on both sides of the center 30WC of the absorbent core 30 in the waist-surrounding direction W, and can mark the position of the absorbent core in the waist-surrounding direction W. Therefore, the absorbent core 30 can be appropriately arranged in the girth direction W, and leakage of excrement can be suppressed.

As shown in fig. 1, the first waistline-side marker unit 511, which is one of the pair of waistline-side marker units, may be disposed in a region overlapping one end in the waistline direction W of the absorbent core 30, and the second waistline-side marker unit 512, which is the other of the pair of waistline-side marker units, may be disposed in a region overlapping the other end in the waistline direction W of the absorbent core 30. Both ends of the absorbent core 30 in the girth direction W are portions where body fluid reaches immediately before leakage of body fluid occurs. The user can grasp the positions of both ends of the absorbent core 30 in the girth direction W, and can dispose the absorbent core 30 so as not to cause leakage.

The first waist marker 511 may be disposed outward in the waist circumferential direction W from one end edge 30WE1 in the waist circumferential direction W of the absorbent core 30, and the second waist marker 512 may be disposed outward in the waist circumferential direction W from the other end edge 30WE2 in the waist circumferential direction W of the absorbent core 30. The user can grasp the position of the region where the absorbent core 30 is not disposed by the mark 50 disposed on the outer side in the girth direction W, and can dispose the absorbent core 30 so as not to cause leakage.

Note that the mark 50 disposed outside the one end edge 30WE1 in the girth direction W of the absorbent core 30 in the girth direction W may be integrated with the mark 50 overlapping the one end portion in the girth direction W of the absorbent core 30, or may be formed separately. Similarly, the mark 50 disposed outside the other end edge 30WE2 in the girth direction W of the absorbent core 30 in the girth direction W and the mark 50 overlapping the other end portion in the girth direction W of the absorbent core 30 may be integrated or may be formed separately.

Preferably, each of the first waist side mark portions 511 and the second waist side mark portions 512 may straddle the end edge of the absorbent core 30 in the waist direction W or the end edge of the absorbent core 30 in the cross direction Z. The first mark portion 51 of the present embodiment is constituted by a printed portion provided on the inner surface of the back surface film 21. The first mark portion 51 is disposed in a region overlapping with the absorbent core 30 and a region not overlapping with the absorbent core 30. When the first mark 51 is visually recognized from the inner surface side of the pet diaper, the first mark 51 in the region not overlapping the absorbent core 30 is highly visually recognized, and the first mark 51 in the region overlapping the absorbent core 30 is less visually recognized, so that a part of the first mark 51 is visually recognized. The position of the end edge of the absorbent core can be easily grasped by the difference in the visual confirmation of the first mark portion 51.

A plurality of first mark portions 51 may be arranged at intervals in the intersecting direction Z. Specifically, the center mark portions 513 may be disposed at intervals in the intersecting direction Z, the first waist mark portions 511 may be disposed at intervals in the intersecting direction Z, and the second waist mark portions 512 may be disposed at intervals in the intersecting direction Z. Since the plurality of marking portions are arranged along the intersecting direction Z, alignment can be performed based on the marking portions in various directions (for example, in the case of visual confirmation from the front side or in the case of visual confirmation from the rear side).

The first mark portions 51 may be disposed on both sides across the center 30WC of the absorbent core 30 in the cross direction Z. Specifically, the center mark 513 may be disposed as a pair on both sides of the center 30WC of the absorbent core 30, the first waistline mark 511 may be disposed as a pair on both sides of the center 30WC of the absorbent core 30, and the second waistline mark 512 may be disposed as a pair on both sides of the center 30WC of the absorbent core 30. Therefore, the pair of center mark portions 513, the pair of first waist mark portions 511, and the pair of second waist mark portions 512 function as "a pair of intersecting side mark portions" in the present invention, respectively. The user can easily grasp the position of the absorbent core 30 in the cross direction Z by the cross side mark portions disposed on both sides with respect to the center of the absorbent core 30 in the cross direction Z. Therefore, it is possible to appropriately arrange the absorbent core 30 in the crossing direction Z and suppress leakage of excrement.

One of the pair of cross-side mark portions may be disposed in a region overlapping one end portion of the absorbent core 30 in the cross direction Z, and the other of the pair of cross-side mark portions may be disposed in a region overlapping the other end portion of the absorbent core 30 in the cross direction Z. Specifically, as shown in fig. 1, the first waistline-side marker portions 511 on one end portion side (left side in fig. 1) in the intersecting direction Z of the pair of first waistline-side marker portions 511 may be disposed in a region overlapping with one end portion in the intersecting direction Z of the absorbent core 30, and the first waistline-side marker portions 511 on the other end portion side (right side in fig. 1) in the intersecting direction Z may be disposed in a region overlapping with the other end portion in the intersecting direction Z of the absorbent core 30. The user can grasp the positions of both end portions of the absorbent core 30 in the cross direction Z, and can arrange the absorbent core so as not to cause leakage.

One of the pair of intersecting side marks may be disposed outward in the intersecting direction Z from one end edge 30ZE1 in the intersecting direction Z of the absorbent core 30, and the other of the pair of intersecting side marks may be disposed outward in the intersecting direction Z from the other end edge 30ZE2 in the intersecting direction Z of the absorbent core 30. Specifically, the first waist mark 511 on one end portion side (left side in fig. 1) in the intersecting direction Z may be disposed outward in the intersecting direction Z from one end edge 30ZE1 in the intersecting direction Z of the absorbent core 30, and the first waist mark 511 on the other end portion side (right side in fig. 1) in the intersecting direction Z may be disposed outward in the intersecting direction Z from the other end edge 30ZE2 in the intersecting direction Z of the absorbent core 30. The user can grasp the position of the region where the absorbent core 30 is not disposed by the mark portion 50 disposed on the outer side in the cross direction Z, and can dispose the absorbent core 30 so as not to cause leakage.

As shown in fig. 2, the back sheet 20 may be provided with a printing region R1 in which a design including the mark 50 is printed and a non-printing region R2 in which printing is not performed. The non-printing regions R2 may be provided at least at both ends of the back sheet 20 in the cross direction Z. The user can grasp both ends in the intersecting direction Z of the main body 2 through the boundary between the non-printing region R2 and the printing region R1. Further, by providing the non-printing region R2, the printing region R1 becomes more conspicuous, and the visibility of the marker 50 in the printing region R1 can be further improved. The boundary between the non-printed region R2 and the printed region R1 may extend in the girth direction W and be located outside the absorbent core 30 in the crossing direction Z. That is, the non-printing region R2 may be disposed only on the outer side of the absorbent core 30 in the cross direction Z. The user can grasp the region where the absorbent core 30 is not disposed by the non-printing region R2, and can dispose the absorbent core 30 so that leakage does not occur.

Next, a pet diaper 1X of the second embodiment will be described. The diaper for pet of the second embodiment is a diaper for cat. In the modification, a diaper for dogs may be used. In the following description of the other embodiments, the same reference numerals are used for the same components as those of the first embodiment, and the description thereof is omitted. Fig. 5 is a plan view of the pet diaper of the second embodiment as viewed from the skin surface side. Fig. 6 is a plan view of the pet diaper 1X of the second embodiment as viewed from the non-skin surface side. Fig. 7 is a view schematically showing a wearing state of the pet diaper 1X according to the second embodiment.

The pet diaper 1X has a main body 2X and a joint 40X. The pet diaper 1X of the second embodiment is worn so as to cover the pet from the abdomen side to the back side through the crotch portion. Therefore, the length of the pet diaper 1X of the second embodiment in the intersecting direction Z is longer than the length of the pet diaper of the first embodiment in the intersecting direction Z. The length of the body 2X in the cross direction Z is longer than the length of the body 2X in the girth direction W. The joining portions 40X are provided at one end portion in the intersecting direction Z of the main body portion 2X with fastening tapes 90 extending outward in the girth direction W from the main body portion 2X. The joining portion 40X is disposed on the inner surface 2P of the main body portion 2X, and is configured to be engageable with a target portion 45 provided on the outer surface 2Q of the main body portion 2. In the modification, the main body may be configured not to include the target portion, and the joining portion 40X may be joined to the back sheet on the outer surface 2Q side of the main body 2X. The joining portions 40X may extend on both outer sides in the girth direction W of the body portion 2X on the side in contact with the abdomen side of the body portion 2X, or may extend on both outer sides in the girth direction W of the body portion 2X on the side in contact with the back side of the body portion 2X.

When the pet diaper 1X is worn, one end portion in the cross direction Z of the main body portion 2X (the end portion on the side where the joint portion 40X is provided) is brought into contact with the abdomen of the pet. At this time, the other end portion in the crossing direction Z of the main body portion 2X is passed between the legs of the pet and is projected toward the rear side of the pet. The center of the body 2X in the intersecting direction Z is brought into contact with the excretory opening of the pet, and the other end of the body 2X in the intersecting direction Z covers the hip and back of the pet. Next, the joint portion 40X is pulled toward the back of the pet, and the target portion 45 at the other end portion in the crossing direction of the body portion located on the back side is fixed to the outer surface. As a result, as shown in fig. 7, the pet diaper 1X can be worn so as to cover the abdomen, back, and crotch of the pet. The pet diaper 1X is preferably disposed so as to cover the back side of the pet from the abdomen side through the crotch portion, and the intersecting direction of the body portion is appropriately along the center of the pet in the left-right direction. Therefore, the pet diaper 1X may have a crossing center mark portion 50ZC that identifies the center 30ZC of the absorbent core 30 in the crossing direction Z. The crossing center mark section 50ZC may be formed of an indication mark.

The pet diaper 1X may be provided with a tail hole portion 60 into which a tail of a pet can be inserted. In the diaper having the tail hole portion 60, when the other end portion in the crossing direction Z of the main body portion 2X covers the buttocks and the back of the pet when worn, the tail of the pet can be inserted through the tail hole portion 60.

As shown in fig. 5, the marker 50 may have an expansion marker 55 disposed in a region overlapping with the expandable member. The stretch mark portion 55 of the present embodiment is disposed in a region overlapping the side stretchable member 13. The stretch mark portion 55 may overlap at least a part of the stretchable member in a plan view. The stretchable member is stretched in at least one of the girth direction W and the crossing direction Z, and is worn in close contact with the body of the pet. Since the stretchable marker 55 is disposed in the region overlapping with the stretchable member, the user can grasp the position of the stretchable member in close contact with the body, and can dispose the stretchable member at an appropriate position.

As shown in fig. 6, the marker 50 may have an interfacing marker 56. Specifically, the back surface film 21 is printed with a first decorative portion 27 and a second decorative portion 28 having a design different from that of the first decorative portion 27. The boundary between the first decorative portion 27 and the second decorative portion 28 constitutes a boundary mark portion 56. The first decorative portion 27 is disposed in a region overlapping the absorbent core 30, and the second decorative portion 28 is disposed in a region not overlapping the absorbent core. The boundary mark portion 56 of the present embodiment is provided along the end edge in the cross direction Z of the absorbent core 30, and is provided along the end edge in the girth direction W of the absorbent core 30. According to this aspect, the decoration can be improved by the two designs of the first decorative portion 27 and the second decorative portion 28, and the alignment can be performed by the marking portion.

The pet diaper 1X may have an end edge marking portion 57 for marking an outer end edge of the main body portion 2X in the intersecting direction Z. The end edge mark portion 57 marks the position of the outer end edge of the main body portion 2X in the intersecting direction Z. By providing the edge mark portion 57, the outer edge in the cross direction Z of the main body portion 2X can be appropriately arranged, and the entire main body portion 2X can be worn in an appropriately wound form, so that the fit can be improved, and the uncomfortable feeling due to excessive tightening can be reduced. The end edge mark portion 57 may be any mark portion that serves as a reference for positioning the outer end edge of the main body portion 2X in the intersecting direction Z. Specifically, the edge mark 57 may be a first edge mark 571 indicating a position at which the one outer edge 2X1 of the body portion 2X in the cross direction Z should be aligned, a second edge mark (not shown) indicating a position at which the other outer edge 2X2 of the body portion 2X in the cross direction Z should be aligned, or a third edge mark 573 capable of determining whether or not the outer edge of the body portion 2X in the cross direction Z is properly arranged. The first edge marker 571 functions in a mode in which one outer edge 2X1 in the cross direction Z of the main body 2X is fitted inside the cross direction Z of the other outer edge 2X2 in the cross direction Z of the main body 2X. The second edge marker functions in a mode in which the other outer end edge 2X2 in the intersecting direction Z of the main body 2X is worn on the inside in the intersecting direction Z than the one outer end edge 2X1 in the intersecting direction Z of the main body 2X. The diaper 1X of the present embodiment is suitably configured such that one outer end edge 2X1 in the cross direction Z of the main body 2X is worn on the inside in the cross direction Z of the other outer end edge 2X2 in the cross direction Z of the main body 2X, and includes a first end mark 571.

As shown in fig. 7, third edge marker 573 is disposed on one outer edge 2X1 side of main body portion 2X and on the other outer edge 2X2 side of main body portion 2X, respectively. Third end mark 573 may be configured such that, in a state where the outer end edge of main body portion 2X in the intersecting direction Z is appropriately disposed, the mark disposed on one outer end edge 2X1 side and the mark disposed on the other outer end edge 2X2 side coincide in the intersecting direction Z. According to the pet diaper, if the outer end edges of both sides in the intersecting direction Z of the main body portion 2X are worn so as to be aligned with each other, the shape of the pet diaper may not be suitable. In this case, by providing the end edge mark 57, the body 2X can be worn with the outer end edges of both sides shifted in the intersecting direction Z, and the shape can be easily adapted to the shape of the body of the pet. For example, a diaper for an infant, which is worn so as to cover the back side of the diaper from the abdomen side of the wearer through the crotch portion, can be worn with the wearing position shifted in the longitudinal direction, and generally, one end in the cross direction is aligned with the other end. However, in a pet diaper having a tail hole portion, it is difficult to shift the wearing position in the longitudinal direction, and one end and the other end in the intersecting direction may not coincide with each other along the body of the pet. In this case, if the user wears the garment so that one end and the other end in the cross direction coincide with each other, there may be a problem that the abdomen is tensed or slackened. However, according to the present embodiment, the pet can be continuously worn at an appropriate position based on the positional relationship of the marker in a state of being appropriately worn on the pet.

At least one marker 50 of the plurality of markers 50 may be disposed in a region sandwiched between the pair of leg hole openings 65. In a diaper worn so as to cover the pet from the abdomen side to the back side through the crotch portion, the joining portion 40X is preferably fixed along a line (FL in fig. 7) extending from the root of the leg on the abdomen side to the back side. By fixing the joint portion 40X along a line extending from the root of the leg on the ventral side toward the dorsal side, the leg circumferences are fitted together, and leakage and misalignment can be suppressed. By disposing the marker 50 in the region sandwiched by the leg hole openings, the joining portion 40X can be locked by the marker 50 in the region along the leg hole.

The end edge mark portion 57 may be disposed in a region that is constant from the outer end edge of the main body portion 2X in the cross direction Z. Specifically, the first region (R11 shown in fig. 6) may be arranged from the outer end edge of the main body 2X in the intersecting direction Z to the base of the leg (the boundary between the leg and the hip). The inner end edge of the first region R11 in the cross direction Z is a portion that coincides with the root of the leg. The user can easily recognize the edge mark 57 when positioning the base of the leg. Preferably, the end edge mark portion 57 may be disposed in a second region (R12 shown in fig. 6) from the outer end edge of the main body portion 2X in the intersecting direction Z to the boundary between the leg and the waist. The inner end edge in the cross direction Z of the second region R12 is a portion coinciding with the intersection of the waist and the leg. The end edge mark portion 57 is easily recognized when the user aligns the waist circumference. The first region R11 and the second region R12 are regions in which positional deviation with respect to leg movement is difficult to occur, and the positional deviation is small once the diaper is worn. The user can correct the positional deviation of the diaper by using the edge mark portion 57 with little positional change as a mark. More preferably, the edge mark portion 57 may be disposed in the third region (R13 shown in fig. 6) where the fastening tape 90 is disposed. The third region R13 is a region extending between the outer edges of the fastening tapes 90 in the crossing direction Z. The user can easily recognize the edge mark portion 57 when gripping the fastening tape 90 and locking the joining portion 40X.

Next, a pet diaper 1Y according to a third embodiment will be described with reference to fig. 8. Fig. 8 is a plan view of the pet diaper 1Y of the third embodiment as viewed from the non-skin surface side. The structure of the pet diaper 1Y other than the marked portion is the same as the diaper 1X of the second embodiment, and the same reference numerals are used and the description thereof is omitted. The pet diaper 1Y of the third embodiment has the area markers 58 as markers. The area mark section is configured to indicate a wearing position of a fixed area extending in the intersecting direction Z of the main body section 2X.

The area marker 58 may include a first area marker 581, and the first area marker 581 may indicate a wearing position of a first area R11 from an outer edge of the main body 2X in the crossing direction Z to a base of a leg (a boundary between the leg and the hip). The first region marker 581 may be provided on one side of the body 2X in the crossing direction Z to indicate a position at which the first region R11 located on the other side of the body 2X in the crossing direction Z is worn, or may be provided on the other side of the body 2X in the crossing direction Z to indicate a position at which the first region R11 located on one side of the body 2X in the crossing direction Z is worn. The first region marker 581 enables alignment between one end side and the other end side of the main body portion 2X in the intersecting direction Z. Further, based on the first region markers 581, the positioning of the diaper with respect to the root of the pet's leg can be performed.

The region marker 58 may have a second region marker 582, and the second region marker 582 indicates the wearing position of the second region R12 from the outer edge of the main body 2X in the intersecting direction Z to the boundary between the leg and the waist. The second region marker 582 may be provided on one side of the body section 2X in the cross direction Z to indicate a position at which the second region R12 located on the other side of the body section 2X in the cross direction Z is worn, or may be provided on the other side of the body section 2X in the cross direction Z to indicate a position at which the second region R12 located on one side of the body section 2X in the cross direction Z is worn. The second area mark 582 enables alignment between one end and the other end of the body 2X in the cross direction Z. Further, based on the second region marker 582, the positioning of the diaper with respect to the legs and waist of the pet can be performed.

The area markers 58 may also have a third area marker 583 indicating the wearing position of the fastening band 90. The third area marking portion 583 is provided on the side of the main body portion 2X to which the fastening tape 90 is fixed. The third area marker 583 allows alignment between one end side and the other end side of the body 2X in the intersecting direction Z. Further, based on the third area markings 583, the relative positions of the target portion 45 and the fastening tape 90 can be appropriately arranged in the intersecting direction Z.

Next, a pet diaper 1Z of a fourth embodiment will be described. The pet diaper 1Z of the fourth embodiment is worn so as to be wrapped around the waist, as in the pet diaper of the first embodiment. Fig. 9 is a plan view of the pet diaper 1Z of the fourth embodiment as viewed from the non-skin surface side. The body 2 has a body 1 st end R21, which is one end of the body 2 in the girth direction W, and a body 2 nd end R22, which is the other end of the body 2 in the girth direction W. The body 1 st end R21 may be a region extending inward in the girth direction W from one end edge 2WE1 of the body 2 in the girth direction W, and may be a region between one end edge 2WE1 of the body 2 and one end edge 30WE1 of the absorbent core 30. The body second end portion 2R 22 may be a region extending inward in the girth direction W from the other end edge 2WE2 of the body portion 2 in the girth direction W, and may be a region between the other end edge 2WE2 of the body portion 2 and the other end edge 30WE2 of the absorbent core 30. The body 1 st end R21 is provided with a joint 40. The engaging portion 40 is configured to be engaged with the body 2 nd end R22 to engage the body 1 st end R21 with the body 2 nd end R22.

The main body 2 has an indicator 70, and the indicator 70 is disposed between the back sheet 20 and the absorbent core 30 and changes color by contact with moisture. The indicator 70 may be disposed between the back sheet 21, which is the back sheet 20, and the absorbent core 30. The indicator 70 extends in the girth direction W. The indicator 70 is disposed across the center of the absorbent core 30 in the girth direction W, and is disposed at least in a portion that comes into contact with the abdomen of the pet when worn. The indicator 70 may be a straight line extending in the girth direction W as shown in fig. 9, or may be an aggregate of indicator structure units arranged at intervals in the girth direction W. The indicator 70 is a straight line extending in the girth direction W. The number of the indicator marks 70 may be one as in the present embodiment, or may be a plurality of the indicator marks arranged at intervals in the intersecting direction Z.

The length of the indicator mark 70 in the girth direction W is 50% or more of the length of the product region R100 extending between the other end edge 2WE2 on the main body 2 end portion side of the main body portion 2 and the joint portion 40. The product region R100 is a region extending in the girth direction W between the other end edge 2WE2 on the body 2 nd end portion side of the main body 2 and the inner end edge in the girth direction W of the joint 40. The pet diaper 1Z of the fourth embodiment is configured to be wound around the waist of a pet, and the indicator 70 is disposed along the waist direction W. The body fluid is drained at the abdomen and the reaction occurs at the abdominal indicator 70. However, in a state where the pet stands while crawling on the four legs, it is difficult for the user (owner) to visually confirm the abdomen, and the color reaction of the indicator 70 may not be confirmed. However, the indicator 70 is disposed in 50% or more of the product region R100, and 50% or more of the girth direction in a state where the pet diaper 1Z is loosely wound. Therefore, in the worn state, the indicator 70 is disposed not only on the abdomen but also on the side of the pet, and the user can easily visually confirm the indicator 70 when wearing the pet.

The main body 2 has a region obtained by quartering the product region R100 in the girth direction W. The quartered region includes a 1 st product region R101 located closest to the 1 st end of the main body, a 2 nd product region R102 located closest to the 2 nd end of the main body, a 3 rd product region R103 adjacent to the 1 st product region R101, and a 4 th product region R104 adjacent to the 2 nd product region R102. The indicator 70 may be disposed in at least one of the 1 st product region R101 and the 2 nd product region R102. The 1 st product region R101 and the 2 nd product region R102 are easily arranged on the side and back of the pet when worn. By disposing the indicator 70 in this region, the visual confirmation of the indicator 70 when worn can be further improved. Further, since the indicator mark 70 extends to the end portion side in the girth direction W of the body 2, the spreading of urine in the girth direction W can be easily visually recognized, and leakage of body fluid can be suppressed.

The indicator 70 may be disposed in both the 1 st product region R101 and the 2 nd product region R102. In the case of leg lifting for urination, urine easily spreads to the 1 st product region R101 or the 2 nd product region R102 under the influence of gravity. Since it is different for the dog which leg is often lifted, leakage prevention can be achieved by arranging both. The indicator 70 may be disposed in both the 3 rd product region R103 and the 4 th product region R104. This is because the 3 rd product region R103 and the 4 th product region R104 are disposed on the abdomen of the pet, and easily guide body fluid. The indicator 70 may span both the 3 rd product region R103 and the 1 st product region R101, and the 4 th product region R104 and the 2 nd product region R102. By disposing the indicator marks across a plurality of regions in this manner, the diffusion pattern of the bodily fluid can be more easily grasped by the indicator marks 70.

The length of the indicator 70 in the waistline direction W may be 50% or more of the length of the absorbent core 30. The indicator 70 is disposed in an area overlapping the absorbent core 30. Preferably, the length of the indicator 70 may be 50% or more of the length of the absorbent core 30 in the waist circumferential direction W in a region overlapping the absorbent core 30. In the diaper wound around the pet in the girth direction W, the region where the absorbent core 30 is disposed is difficult to visually confirm when worn. When the body fluid spreads to a portion where the absorbent core 30 is absent, there is a possibility of causing the hair of the back to be wet. When the amount of the liquid is more than 50% of the amount of the liquid, the timing of replacement can be visually confirmed, and the hair can be prevented from wetting or leaking. Preferably, the length of the indicator 70 in the girth direction W may be 80% or more of the length of the absorbent core 30, and more preferably, the length of the indicator 70 in the girth direction W in a region overlapping with the absorbent core 30 may be 80% or more of the length of the absorbent core 30. With this configuration, the body fluid can be grasped as having spread to the end edges of the absorbent core 30 in the girth direction W.

The back sheet 20 has a printed region R1 where printing is performed and a non-printed region R2 where printing is not performed. The print region R1 is a region where at least one of the back surface film 21 and the back surface nonwoven fabric 22 is printed in a plan view. The non-printing region R2 is a region where printing is not performed on both the back surface film 21 and the back surface nonwoven fabric 22 in a plan view. At least a part of the indicator 70 is disposed in a region overlapping with the non-printing region R2. When the entire area of the indicator 70 overlaps the print area R1, it may be difficult to ensure visual confirmation of the indicator 70 due to printing. However, at least a part of the indication mark 70 is not affected by printing of the back sheet 20, and visual confirmation of the indication mark 70 is easily ensured. Preferably, 50% or more of the area of the indicator 70 may be disposed in the region overlapping with the non-printed region R2. 50% or more of the area of the indication mark 70 is less likely to be affected by printing of the back sheet 20. Therefore, the visibility of the indicator 70 can be improved.

The indicator 70 may be disposed across the boundary between the non-printing region R2 and the printing region R1. The visual confirmation of indicator 70 is different between print region R1 and non-print region R2. By locally differentiating the appearance of the indicator 70, it is easy to grasp the form of the color reaction of the indicator 70, that is, the portion to which the body fluid has spread. The non-printing region R2 of the present embodiment is surrounded by the printing region R1 in four directions. The boundary between the non-printing region R2 and the printing region R1 is rectangular in shape extending in the girth direction in plan view. The indicator mark 70 is disposed across a boundary between the non-printing region R2 and the printing region R1, which boundary is located at both ends of the non-printing region R2 in the girth direction W.

Next, a pet diaper 1V of the fifth embodiment will be described. The pet diaper 1V of the fifth embodiment is worn so as to cover the abdomen of the pet from the crotch to the back, as in the pet diaper of the 2 nd embodiment. Fig. 10 is a plan view of the pet diaper 1V of the fifth embodiment as viewed from the non-skin surface side. The pet diaper 1V has a tail hole portion 60 through which a tail of a pet can pass. The main body 2 has an indicator 70, and the indicator 70 is disposed between the back sheet 20 and the absorbent core 30 and changes color by contact with moisture. The indicator 70 may be disposed between the back sheet 21, which is the back sheet 20, and the absorbent core 30. The index mark 70 extends along the crossing direction Z. The indicator 70 is disposed across the center of the absorbent core 30 in the cross direction Z, and is disposed at least in a portion that comes into contact with the abdomen of the pet when worn. The indication mark 70 may be a straight line extending along the intersecting direction Z as shown in fig. 10, or may be an aggregate of indication mark structural parts arranged at intervals in the intersecting direction Z. The indication mark 70 of the present embodiment is a straight line extending in the intersecting direction Z. As in the present embodiment, the number of the indicator marks 70 may be one, or a plurality of the indicator marks may be arranged at intervals in the girth direction W.

The pet diaper 1V has a partition region R50 that partitions the absorbent core 30 and the tail hole portion 60 in the cross direction Z. The indicator 70 is disposed across the core region overlapping the absorbent core 30 and the separation region R30. The core region is a region in which the absorbent core 30 is arranged in a plan view. If the body fluid reaches the tail hole portion 60, the body fluid may leak through the tail hole portion. However, since the indicator 70 is disposed so as to straddle the core region and the dividing region R50, the spreading of the body fluid over the absorbent core 30 can be detected, and leakage of the body fluid can be suppressed. The absorbent core 30 of the present embodiment is disposed on the outer end edge 2X1 side (the joint portion side) of the main body portion 2X in one of the intersecting directions Z, compared to the tail hole portion 60. Therefore, the dividing region R50 is disposed only on one side of the intersection direction Z with respect to the tail hole portion 60. In more detail, the dividing region R50 extends between the end edge on the outer end edge 2X1 side of the tail hole portion 60 and the end edge on the outer end edge 2X2 side of the absorbent core 30. However, in the modified example, the partition region R50 is disposed on both sides in the intersecting direction Z with respect to the tail hole portion 60 in such a manner that the absorbent core 30 is disposed not only on the outer edge 2X1 side with respect to the tail hole portion 60 but also on the outer edge 2X2 side with respect to the tail hole portion 60. In the embodiment having a plurality of dividing regions R50, the indicator 70 may be disposed in any one of the dividing regions R50.

The indicator 70 may be disposed in the crossing direction Z in 50% or more of the dividing region R50. According to this configuration, the state of diffusion of the bodily fluid in the dividing region R50 can be grasped more appropriately by the indicator 70. Further, indicator 70 may be disposed so as to span aperture section region R60 and partition region R50 that overlap tail aperture section 60. The hole portion region R60 is a region located inward of a line connecting the outer shapes of the tail holes 60, and is indicated by hatching in fig. 10. According to this aspect, it is possible to detect that the body fluid has reached the region overlapping with the tail hole portion 60, and further suppress leakage of the body fluid through the tail hole portion 60.

The indicator 70 of the fifth embodiment is arranged so as to overlap the non-printed region R2, as in the indicator of the fourth embodiment. More than 50% of the area of the indicator 70 may be disposed in the region overlapping with the non-printing region R2. The indicator 70 may be disposed across the boundary between the non-printing region R2 and the printing region R1.

Next, an example of a method for manufacturing the pet diaper configured as described above will be described. The method for producing a pet diaper may comprise: a sheet conveying step of conveying a continuous sheet body obtained by continuously conveying sheets; a marking step of printing the continuous sheet body and providing a marking portion 50; and an absorbent core stacking step of stacking the absorbent core 30 on the continuous sheet member having the marking portion 50.

The sheet conveying step of conveying a continuous sheet body obtained by continuously conveying sheets conveys the continuous sheet body obtained by continuously conveying sheets constituting any one of the front sheet 10, the back sheet, and the core covering sheet. The marking process applies the mark 50 to the continuous sheet material body. The marking portion 50 may be provided by printing or embossing. The core laminating step detects the position of the mark portion 50 of the continuous sheet body. The detection of the marker 50 may be performed by detecting the position of the marker 50 by an imaging means such as a camera. The core stacking step adjusts the stacking position of the absorbent core 30 based on the position of the marker 50. The adjustment of the lamination position of the absorbent core 30 is the adjustment of the position of the absorbent core 30 and the continuous sheet body. Specifically, by adjusting the feeding amount of the continuous sheet body, the position of the continuous sheet body and the absorbent core 30 in the conveying direction can be adjusted. Further, an adjustment mechanism that comes into contact with a side end of the continuous sheet body in a direction orthogonal to the conveying direction may be provided, and the position of the continuous sheet body in the orthogonal direction may be adjusted by the adjustment mechanism. According to such a manufacturing method, the relative position of the mark portion 50 and the absorbent core 30 can be kept constant. Therefore, when the diaper is worn with the mark portion 50 as a reference, the worn position of the absorbent core 30 can be suppressed from shifting for each diaper. The accuracy of positioning by the marking portions 50 can be improved by suppressing the positional deviation of the marking portions 50 in the entire diaper.

Next, a container for containing a plurality of pet diapers in a package will be described. The container has a plurality of diapers for pets and a bag body for containing the plurality of diapers for pets. The plurality of diapers for pets include a first diaper having a first decorative portion printed on a back surface sheet and a second diaper having a second decorative portion having a design different from that of the first decorative portion printed on the back surface sheet. Here, the first decorative portion and the second decorative portion may be different in design from each other, and may be different in design from the first decorative portion and the second decorative portion of the second embodiment. In the present embodiment, the first decorative portion or the second decorative portion is printed on the back surface film of the back sheet. According to the present embodiment, the first diaper having the first decorative portion and the marking portion and the second diaper having the second decorative portion and the marking portion can improve the decorativeness, attract the attention of the user, and improve the visibility of the marking portion. The first decorative portion and the second decorative portion are portions having designs other than the marking portion, and include not only designs having patterns or patterns but also background colors made of only colors.
