Technical Field

The present invention relates to an absorbent article used in a state of being attached to a wearing article such as underwear.

Background

Patent documents 1 and 2 disclose an absorbent article such as a disposable diaper provided with a belt member for post-treatment. One end of the belt member is fixed to the back sheet, and the other end of the belt member is a portion to be pinched at the time of use. When discarding the absorbent article having such a belt member, the user fixes the absorbent article in a rolled state by the belt member while holding the other end of the belt member.

Patent document 3 discloses an absorbent article such as a sanitary napkin provided with a belt member for post-treatment. Such an absorbent article is attached to the inside of a wearing article worn by a user when worn. The belt member is fixed to the back sheet and is disposed so as to face the wearing article when worn.

Disclosure of Invention

In the absorbent articles described in patent documents 1 and 2, the back sheet is disposed on the outer side of the absorbent article when worn, and the belt member can be visually confirmed from the outer side of the absorbent article. This makes it easy for the user to recognize the presence of the tape member, and the tape member can be smoothly wound up for disposal when disposed of.

However, in an absorbent article used in a state of being attached to a wearing article such as underwear as in patent document 3, the back sheet is disposed inside the wearing article when worn, and the belt member cannot be visually confirmed from the outside of the wearing article. Thus, it is sometimes difficult for the user to recognize the presence of the belt member.

Therefore, an absorbent article that is used in a state of being attached to a wearing article and in which a belt member for post-treatment is easily identified is desired.

An absorbent article according to one aspect includes: a front-back direction; a width direction orthogonal to the front-rear direction; a main body part having a front sheet, a back sheet and an absorbent core; and a belt member for post-treatment disposed on the non-skin-facing surface side of the main body portion, the absorbent article being used in a state of being attached to a wearing article, wherein a color difference Δ E between an adjacent region where the non-skin-facing surface of the main body portion is adjacent to the belt member and a recognition region of at least a part of the belt member is 3.0 or more when viewed in a plan view from the non-skin-facing surface side of the absorbent article.

Detailed Description

(1) Brief description of the embodiments

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

An absorbent article according to one aspect includes: a front-back direction; a width direction orthogonal to the front-rear direction; a main body part having a front sheet, a back sheet and an absorbent core; and a belt member for post-treatment disposed on the non-skin-facing surface side of the main body portion, the absorbent article being used in a state of being attached to a wearing article, wherein a color difference Δ E between an adjacent region where the non-skin-facing surface of the main body portion is adjacent to the belt member and a recognition region of at least a part of the belt member is 3.0 or more when viewed in a plan view from the non-skin-facing surface side of the absorbent article.

Since the color difference Δ E between the adjacent region of the main body and the identification region of the belt member is 3.0 or more, the user can easily identify the main body and the belt member as separate bodies and the presence of the belt member.

According to a preferred embodiment, the absorbent article is provided with a fold line along the width direction for folding the absorbent article so that the skin-facing surface side of the absorbent article is positioned inward, and the belt member is disposed outward in the front-rear direction from the fold line.

The region of the absorbent article on the outer side in the front-rear direction than the fold line is apt to float toward the skin-facing surface side from the fold line because of being bent habitually. Since the region on the outer side in the front-rear direction than the fold line is floated by being bent habitually, the non-skin-facing surface of the absorbent article can be visually recognized from the side or the like of the absorbent article more easily than when the absorbent article is flat as a whole. Thus, the user can easily visually confirm the belt member located on the non-skin-facing surface side of the main body portion in a state where the absorbent article is detached from the wearing article.

According to a preferred embodiment, the fold lines are provided at intervals in the front-rear direction, the fold lines have a 1 st fold line closest to a front end edge of the absorbent article and a 2 nd fold line closest to a rear end edge of the absorbent article, and the belt member is disposed in at least one of a front region between the 1 st fold line and the front end edge and a rear region between the 2 nd fold line and the rear end edge.

In the structure in which the plurality of folds are formed, the front end edge and the rear end edge of the absorbent article tend to float from the 1 st fold and the 2 nd fold located at the outermost positions in the front-rear direction due to the habitual folding. Since the belt member is disposed in at least one of the front region and the rear region, the user can easily recognize the belt member when the front region and the rear region are lifted by being bent habitually.

According to a preferred embodiment, a bonding portion for fixing the absorbent article to the wearing article is provided on a non-skin-facing surface of the back sheet, and the identification region is disposed outside in the front-rear direction of an outer end edge in the front-rear direction of the bonding portion.

The region provided with the adhesive portion is fixed to the wearing article during wearing, and is difficult to visually confirm from the skin-facing surface side of the absorbent article. On the other hand, the region on the outer side in the front-rear direction than the region where the adhesive portion is provided is not fixed to the wearing article when worn, and the absorbent article may be curled or floated, and may be visually confirmed from the skin-facing surface side. Since the identification region is disposed at a position further outward in the front-rear direction than the outer edge of the adhesive portion in the front-rear direction, the user can easily visually confirm the band member when wearing the band member, and identify the presence of the band member.

According to a preferred embodiment, the band member has a grip portion that can be gripped by a user, and the identification region is disposed in the grip portion.

The wearer can easily recognize the grip portion of the belt member. The user can smoothly perform the disposal operation by grasping the portion to be pinched at the time of the disposal operation.

According to a preferred embodiment, the grip portion includes one end of the belt member and extends in a region sandwiched between a pair of side edges extending from the one end toward the other end of the belt member, and the adjacent region includes a region adjacent to the one end on the non-skin-facing surface of the main body portion and a region adjacent to the side edges on the non-skin-facing surface of the main body portion.

Since the color difference Δ E between the grip portion and 3 regions disposed so as to surround the grip portion on the non-skin-facing surface of the main body portion is 3.0 or more, the user can easily recognize the grip portion and can perform a smooth disposal operation.

According to a preferred embodiment, at least one of the identification region and the adjacent region is provided with a colored portion that can be visually confirmed from a skin-facing surface side of the absorbent article so as to penetrate through the main body portion.

Since the colored portion can be visually confirmed from the skin-facing surface side of the absorbent article, the user can recognize the presence of the belt member when wearing the absorbent article.

According to a preferred embodiment, the belt member has a base layer and a printed layer overlapping with the base layer in a thickness direction, and the printed layer is disposed on a skin-facing surface side of the base layer and is visually confirmed from a non-skin-facing surface side of the absorbent article as being transmitted through the base layer.

Since the printed layer is disposed on the skin-facing surface side of the foundation layer, the printed layer can be visually confirmed without interposing the foundation layer therebetween when visually confirming from the skin-facing surface side of the absorbent article, and the presence of the belt member can be easily recognized when wearing the absorbent article. Further, since the base layer is disposed on the non-skin-facing surface side of the printed layer, the printed layer is less likely to rub against the wearing article, and the printed layer can be prevented from being unexpectedly obscured.

According to a preferred aspect, a colored portion having a guide portion for guiding an operation of the belt member is provided at least one of the identification region and the adjacent region.

The user can grasp the operation of the belt member by the guide portion, and can perform a smooth disposal operation.

(2) Structure of absorbent article

Hereinafter, an absorbent article according to an embodiment will be described with reference to the drawings. The absorbent article may be an absorbent article such as a sanitary napkin, panty liner, breast pad, adult incontinence pad, fecal pad or sweat pad. The absorbent article may be used by being attached to the inside of a wearing article such as underwear.

In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. In the drawings, the drawings are schematic, and it should be noted that the scale of each dimension and the like may be different from the actual scale and the like. 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.

Fig. 1 is a plan view of an absorbent article 10 according to embodiment 1, as viewed from the skin-facing surface side. Fig. 2 is a plan view of the absorbent article 10 according to embodiment 1, viewed from the non-skin-facing surface side. Here, the "skin-facing surface side" corresponds to a side facing the skin of the wearer during use. The "non-skin-facing side" corresponds to the side that faces away from the skin of the wearer during use. Fig. 3 is a cross-sectional view taken along line a-a shown in fig. 1, and fig. 4 is a perspective view of the absorbent article in a rolled state in the front-rear direction.

The absorbent article 10 has a front-back direction L and a width direction W the front-back direction L is a direction extending from the front side (ventral side) to the rear side (dorsal side) of the wearer or a direction extending from the rear side to the front side of the wearer the width direction W is a direction orthogonal to the front-back direction L.

The absorbent article 10 has a main body portion 20 and a belt member 60 for post-treatment, the main body portion 20 includes a surface sheet 21 facing the skin of the wearer, a back sheet 22 facing the opposite side of the skin of the wearer, and an absorbent core 23 disposed between the surface sheet 21 and the back sheet 22, the surface sheet 21 faces the skin of the wearer during use, the back sheet 22 faces the opposite side of the skin of the wearer during use, and the absorbent core 23 includes an absorbent material for absorbing body fluid and extends in the front-rear direction L of the absorbent article.

The main body portion 20 may also have wings 40 and hip flaps 50. The flap 40 is folded back toward the non-skin-facing surface side of the crotch portion of the worn article during use. The hip flap 50 is a portion that bulges in the width direction W at a position rearward of the flap 40. The hip flaps 50 are portions bulging outward in the width direction W from the outer edge of the absorbent core 23.

The main body portion 20 has an excretory opening opposing region S1 that opposes an excretory opening (e.g., vaginal opening) of a wearer during use. The excretory opening opposing region S1 is a region disposed in the crotch of the wearer, i.e., between the legs of the wearer, and corresponds to a region where the absorbent core 23 is present. In addition, in the absorbent article 10 having the flaps 40, the excretory opening opposing region S1 is between the flaps 40, and corresponds to the region where the absorbent core 23 is present.

As shown in fig. 2, the main body portion 20 may have adhesive portions 42, 52, 70 provided on the non-skin-facing side of the back sheet 22. The adhesive sections 42, 52, 70 are regions provided with an adhesive for fixing the absorbent article 10 to a wearing article. The bonds may include a body bond 70, a flap bond 42, and a flap bond 52.

The absorbent article 10 can be fixed to a wearing article such as underwear by the adhesive sections 42, 52, 70 provided on the non-skin-facing surface side of the back sheet 22. Further, after the absorbent article 10 is used, the tape member 60 may be fixed by the adhesive portions 42, 52, and 70 in a state where the absorbent article 10 is rolled up, and the rolled-up state may be maintained. Therefore, the adhesive portions 42, 52, and 70 can be used for both the purpose of fixing to the clothes and the purpose of fixing the belt member for the post-treatment.

The body bond 70 is provided in a region overlapping the absorbent core 23 in the thickness direction of the absorbent article 10. preferably, the body bond 70 extends continuously or intermittently from at least the excretory opening opposing region S1 toward the rear of the absorbent article 10. the body bond 70 may extend in the front-rear direction L and be provided in plural at intervals in the width direction W. in other forms, the body bond 70 may extend in the width direction W and be provided in plural at intervals in the front-rear direction.

The flap adhesive portion 42 is provided to the flap 40. The flap 40 is folded back toward the wearing article of the wearer during use, and attached to the non-skin-facing surface side of the wearing article by the flap adhesive portion 42. The flap adhesive 52 is provided to the hip flap 50.

The absorbent article 10 may also have a fold extending in the width direction W. In the example shown in fig. 1 and 2, the folds of the absorbent article 10 have the 1 st fold F1, the 2 nd fold F2, and the 3 rd fold F3. The 1 st fold F1 is the fold closest to the front end edge E1 of the absorbent article 10. The 2 nd fold F2 is the fold closest to the rear end edge E2 of the absorbent article 10. The 3 rd fold F3 is disposed between the 1 st fold F1 and the 2 nd fold F2. In addition, more than 4 folds can be arranged. The fold line is a line for folding the absorbent article 10 so that the skin-facing surface side T1 of the absorbent article is on the inside when the absorbent article is packaged.

The band member 60 is fixed to the main body portion 20. As shown in fig. 3, the band member 60 may have a fixing portion 62 fixed to the main body portion 20. The fixing portion 62 may be provided at one end of the band member 60. The fixing portion 62 may be fixed to the main body portion 20 by an adhesive means such as an adhesive. The fixing portion 62 may be fixed to the back sheet 22 constituting the non-skin-facing surface of the main body portion 20.

In addition, the belt member 60 may have a non-fixing portion 64 that is not fixed to the main body portion 20. The non-fixing portion 64 is a portion that is not fixed to the back surface sheet 22 and allows a user to operate the belt member 60. More specifically, when the user uses the band member 60, the user grips the non-fixing portion and pulls the non-fixing portion 64, thereby fixing the non-fixing portion 64 to the main body portion 20. At least a part of the non-fixed portion 64 constitutes a grip portion 65 that can be gripped by a user. The grip portion 65 may be provided over the entire non-fixed portion 64, or may be provided on one end side of the non-fixed portion 64 opposite to the fixed portion 62. The belt member of the present embodiment has one end 60A opposite to the fixed portion, the other end 60C on the fixed portion side, and a pair of side edges 60B extending from the one end 60A toward the other end 60C. The grip portion 65 includes one end 60A of the belt member 60 and extends in a region sandwiched by a pair of side edges 60B extending from the one end 60A toward the other end 60C of the belt member. The grip portion 65 may be configured to be gripped by a user.

The non-anchor portion 64 may be configured to be extensible in an extension direction, the extension direction D of the non-anchor portion 64 may be a direction from the anchor portion 62 toward the non-anchor portion 64, and for configurations in which the anchor portion 62 and the non-anchor portion 64 are adjacent in the front-rear direction L, the extension direction D may be the front-rear direction L.

The belt member 60 may be configured to be fixed to the main body portion 20 in a rolled state with the skin-facing surface side of the absorbent article being on the inner side when the absorbent article 10 is discarded, and to maintain the rolled state of the absorbent article 10. The non-fixing portion 64 of the belt member 60 is configured to be fixable to the main body portion 20. The non-fixing portion 64 may be fixed to the main body 20 by an adhesive portion of the main body 20, or may be a fixing means such as an adhesive agent or a hook member provided on the tape member 60. The fixing portion 62 of the tape member 60 may be configured to be fixable to the main body portion 20. The fixing portion 62 may be a bonding portion of the main body 20, or may be a fixing means such as an adhesive or a hook member provided on the tape member 60.

The non-fixing portion 64 of the tape member 60 of the present embodiment is fixed to the main body 20 via the main body adhesive portion 70 at the time of disposal. In the structure in which the tape member 60 is fixed to the main body portion 20 by the adhesive portion of the main body portion 20, a fixing means such as an adhesive may not be provided in the non-fixing portion 64.

At least the non-fixing portion 64 of the belt member 60 is configured to be extensible in the extension direction D. At least the non-fixing portion 64 of the belt member 60 is configured to be extensible in the extension direction D, and therefore when the rolled absorbent article 10 is fixed by the belt member 60, the absorbent article 10 is easily fixed by the belt member 60 (see fig. 4). The tape member 60 may be configured such that the entire portion including the fixed portion 62 is extensible in the extending direction D, or only the non-fixed portion 64 is extensible. Herein, "elongation" includes elongation caused by "elastic deformation" or "plastic deformation". For example, the belt member 60 may be formed of a stretchable sheet or a film.

As shown in fig. 2, the belt member 60 may be disposed inward of the outer edge 20E of the main body portion 20 in an unstretched state (natural state). the belt member 60 may be hidden in the main body portion 20 when viewed from the skin-facing surface side. as shown in fig. 4, the belt member 60 may be extended outward of the outer edge 20E of the main body portion 20 in an stretched state (stretched state). after the absorbent article 10 is used, the user can wind up the main body portion 20 in the front-rear direction L, and then extend the belt member 60 outward of the outer edge 20E of the main body portion 20 to fix the belt member 60 to the main body portion 20 (see fig. 4).

With such a configuration, the belt member 60 is disposed on the non-skin-facing surface side of the back sheet 22 on the inner side of the outer edge 20E of the main body portion 20 during use of the absorbent article 10, and therefore, body fluid such as menstrual blood does not adhere thereto. After the absorbent article 10 is used, the user can hold the absorbent article 10 in a rolled-up state by fixing the belt member 60 extending outward to the main body adhesive portion 70 and the like. Here, since body fluid such as menstrual blood does not adhere to the belt member 60, a reduction in the joining force between the belt member 60 and the main body adhesive portion 70 or a reduction in the joining force of the fixing means of the belt member can be prevented. Further, since the belt member 60 is provided on the non-skin-facing surface side of the back sheet 22 and does not extend outward beyond the outer edge 20E of the main body portion 20 during use of the absorbent article 10, the belt member 60 does not directly contact the skin of the wearer. Therefore, the uncomfortable feeling and the unpleasant feeling during the use can be reduced.

In another embodiment, the belt member 60 may extend outward from the outer edge 20E of the main body 20 in an unstretched state (natural state). The belt member 60 may be in a state of being visually recognizable when viewed from the skin-facing surface side.

As another example, the belt member 60 may be formed of a sheet folded in a Z-shape. In the state of being folded in the Z-shape, at least a part of the surface of the belt member 60 facing the main body portion 20 can be fixed to the main body portion 20. In the region where the sheets constituting the belt member 60 overlap each other, the sheets may be bonded to each other so as to be peelable. In this case, the wearer pulls the distal end of the belt member 60, and the folded belt member 60 is unfolded, whereby the belt member 60 is extended outward from the outer edge of the main body portion 20.

The belt member 60 is preferably provided at a position more rearward than the center in the front-rear direction L of the main body portion 20. when a user normally rolls up the absorbent article 10, the user starts rolling up from the front end edge E1 or the rear end edge E2 of the absorbent article 10 in the front-rear direction L. of these, the user who is about 8 rolls up from the front end edge E1 of the absorbent article 10. accordingly, the belt member 60 is preferably provided in a region located more rearward than the center in the front-rear direction, and at least a part of the belt member 60 may be disposed over the rear end edge of the absorbent core 23 or more rearward than the rear end edge of the absorbent core.

The belt member 60 may be disposed at a position further outward in the front-rear direction than the 1 st fold F1 to the 3 rd fold F3. The region of the absorbent article on the outer side in the front-rear direction than the fold line is apt to float toward the skin-facing surface side from the fold line because of being bent habitually. Specifically, for example, when the belt member 60 is disposed between the fold and the rear end edge of the absorbent article, if the region on the front side of the fold is grasped and visually recognized from the skin-facing surface side of the absorbent article, the region between the fold and the rear end edge of the absorbent article floats up toward the skin-facing surface side from the fold as a starting point. Since the region between the fold and the rear end edge of the absorbent article floats, the non-skin-facing surface of the absorbent article can be visually recognized more easily from the side of the absorbent article than when the entire absorbent article is flat. Thus, the user can easily visually confirm the belt member 60 located on the non-skin-facing surface side of the main body portion in a state where the absorbent article is detached from the worn article.

Specifically, in the configuration in which the fold is 1, the belt member 60 may be disposed apart from the fold in the front-rear direction L instead of being disposed on the fold, and in the configuration in which the fold is multiple, the belt member 60 may be disposed in at least either one of the front region R1 between the 1 st fold F1 and the front end edge E1 and the rear region R2 between the 2 nd fold F2 and the rear end edge E2, the belt member 60 of the present embodiment may be disposed in the rear region R2 between the 2 nd fold F2 and the rear end edge E2, in the configuration in which the multiple folds are formed, the front end edge E1 and the rear end E2 of the absorbent article 10 are easily bent with the 1 st fold F1 and the 2 nd fold F2 located at the outer side in the front-rear direction L as starting points, and the belt member 60 is easily bent with the front region R1 and the rear region R582 as starting points, and therefore, the user easily recognizes that the belt member 60 is bent with the front region R2 and the habitually bent.

More preferably, the belt member 60 is provided on the rear side of the 2 nd fold F2, which is the rearmost fold among the 1 st fold F1 to the 3 rd fold F3. A user who turns around 8 turns the used absorbent article 10 from the front side. The belt member 60 is provided at a position on the rear side of the 2 nd fold F2, so that many users start rolling up from the front end edge E1 of the absorbent article 10 and can fix the rolling-up end portion with the belt member 60.

The non-fixing portion 64 may be detachably joined to the non-skin-facing surface of the main body portion by a temporary fixing portion not shown. By providing the temporarily fixing portion, the unfixed portion 64 can be prevented from being rolled up or the unfixed portion 64 can be prevented from being bent before the tape member 60 is used (during manufacturing or wearing). The engaging force of the temporarily fixing portions may be lower than that of the fixing portions 62. Since the engagement force of the temporarily securing part is lower than the engagement force of the securing part 62, the user can easily peel the temporarily securing part when using the tape member 60, and can operate the tape member 60 by pinching the unfixed part 64. As the fixing means of the temporary fixing portion, an adhesive, embossing, thermal welding, or ultrasonic welding can be exemplified, and the amount of application (area, basis weight) of the adhesive can be reduced as compared with the fixing portion 62, or the compression of the embossing can be reduced as compared with the fixing portion 62. The temporary fixing portion may be formed by embossing on the outer edge of the main body portion.

An example of a specific configuration of the absorbent article of the present embodiment is shown. The surface sheet may consist of a weight per unit area of 30g/m²The hot air non-woven fabric (PE/PET). A second sheet may be provided between the topsheet and the absorbent core. The second sheet may be made of the same material as the surface sheet. The side sheet may be disposed outside the body in the width direction without disposing the front sheet. The side sheet may have a weight per unit area of 13g/m²The SMS nonwoven fabric (PP) of (1). The absorbent material of the absorbent core may be composed of softwood kraft pulp and a superabsorbent polymer. The ratio of the weight of the superabsorbent polymer to the weight of the absorbent material as a whole may be 10% of the total weight of the composition. The weight per unit area of the absorbent core in the region including the excretory opening opposing region S1 may be configured to be higher than the weight per unit area of the surrounding absorbent core. The absorbent core of the region comprising the excretory opening opposing region S1 may have a weight per unit area of 950g/m²The weight per unit area of the surrounding absorbent core may be 300g/m². The back sheet may have a basis weight of 23.5g/m²Is made of a polyethylene film (non-breathable type). The absorbent article may be formed with a compressed portion obtained by compressing the topsheet and the absorbent core in the thickness direction. The main body bonding part may be made of a rubber-based hot-melt adhesive. The weight per unit area of the main body bonding part may be 27g/m². The body bonding portion may be provided with 6 strips at intervals in the width direction. The length of each body bonding portion in the width direction may be 5mm, and the length of each body bonding portion in the front-rear direction may be 320 mm. The length of the absorbent article in the front-rear direction may be 420mm, and the length of the absorbent article in the width direction may be 200 mm. The belt member for post-treatment may be composed of a weight per unit area of 35g/m²The polyethylene film of (1). The length of the belt member in the longitudinal direction may be 45mm, and the length of the belt member in the short direction may be 25 mm. The belt member can use a weight per unit area of 100g/m²The rubber-based hot-melt adhesive is fixed to the main body. The adhesive may be applied in a range of 21mm in width and 5mm in length. The back sheet side of the tape member may be printed. For printing, a pink urethane ink can be used. Further, the extensible belt member may be constituted by a weight per unit area of 10g/m²Polypropylene layer of (2), weight per unit area 10g/m²Styrene-based rubber layer and a weight per unit area of 10g/m²Is laminated with the polypropylene layer of (a).

Next, the identification region RA and the adjacent region RB of the band member 60 configured as above will be described. The identification region RA and the adjacent region RB have a function that a user can easily identify the main body portion 20 and the band member 60 as separate bodies. For example, if the user does not recognize the presence of the belt member 60, the absorbent article cannot be cleanly discarded using the belt member 60. Further, if it is difficult for the user to recognize the presence of the belt member 60, the user needs to confirm the entire used absorbent article without a dead space, and the following disadvantages may occur: unpleasant feeling is generated, or hands are stained with body fluid. The user can easily recognize the main body portion 20 and the belt member 60 as separate bodies, so that the user can easily recognize the presence of the belt member 60 and cleanly discard the absorbent article 10 using the belt member 60.

The identification region RA may be configured to be easily conspicuous on the non-skin-facing surface of the main body portion 20 with respect to the adjacent region RB adjacent to the belt member 60. Specifically, the color difference Δ E between the identification region RA and the adjacent region RB may be 3.0 or more. As a result of various studies, the applicant found that, in general, when the color difference Δ E is 3.0 or more, a user can easily recognize two regions as different regions. Since the color difference Δ E between the adjacent region RB of the main body 20 and the identification region RA of the belt member 60 is 3.0 or more, the user can easily identify the main body 20 and the belt member 60 as separate bodies, and can easily identify the presence of the belt member 60. The adjacent region RB may be a region adjacent to the outer edge (including the one end 60A, the side edge 60B, and the other end 60C) of the belt member 60 on the non-skin-facing surface of the main body portion 20. The region is a region having a certain range from any outer edge of the belt member 60 toward the outer side of the belt member 60. In fig. 2, adjacent regions RB are indicated by diagonal lines. In a structure in which adjacent regions are provided on four sides of the belt member, the color difference Δ E between at least one adjacent region RB and the identification region RA may be 3.0 or more.

The color difference Δ E between the identification region RA and the adjacent region RB can be obtained by measuring the color of two points (two regions) to be measured using a commercially available color measuring instrument and comparing the values obtained by digitizing the CIE1976 (L a b) color space defined in japanese industrial standard JIS Z8729, specifically, when the difference between L a and b between the two points to be measured is Δ L, the difference between a and b is Δ b, the color difference Δ E is [ (Δ L) ]²+(Δa*)²+(Δb*)²]^1/2And (6) obtaining.

In the configuration in which the color difference is provided between the identification region RA and the adjacent region RB, the colored portion may be provided in the identification region RA of the belt member 60, the colored portion may be provided in the back sheet 22 constituting the non-skin-facing surface of the main body portion 20, the colored portion may be provided in a member (for example, the absorbent core 23) positioned closer to the skin-facing surface side T1 than the back sheet 22 of the main body portion 20, and the colored portion may be visually recognized through the back sheet 22, or the colored portion may be provided in both the belt member 60 and the main body portion 20. The colored portion may have at least one of a main body colored portion 91 provided in the main body portion 20 and a belt colored portion 92 (see fig. 5) provided in the belt member 60.

The colored portion may be formed of a sheet itself such as a tape member colored with a pigment or the like, or may be formed of a printed layer. In the present embodiment, the visually recognizable state is a state that can be visually recognized in an environment where the illuminance (lx) is from 100(lx) to 1000 (lx).

The absorbent article 10 of the present embodiment has the colored fastening portion 92 provided in the identification region RA. The belt member 60 has a base layer 66 and a printed layer 67 overlapping the base layer 66 in the thickness direction. The printed layer 67 constitutes a colored portion 92. The belt member 60 is provided with a belt colored portion 92 formed of the printed layer 67 over the entire area thereof. Thus, the identification region RA is provided over the entire region of the belt member 60. As in modification 1 described later, the identification region RA may be provided in a part of the belt member 60.

In addition, it is preferable that the printing layer 67 is not provided on the entire region of the side edge of the extensible belt member 60 in the extension direction D. Since the base material is affected by the printing ink, the elongation at the time of elongation is different between the region where the printing layer is disposed and the region where the printing layer is not disposed, and the elongation at the portion where the printing layer 67 is provided is reduced. Therefore, for example, if the printed layer 67 having a reduced extensibility is locally disposed on the side edge of the belt member 60 in the extension direction D, cracks may occur at the side edge of the belt member 60. In particular, the side edge of the belt member 60 in the extension direction is easily stressed during extension, and cracks are more likely to occur. However, by not providing the printed layer 67 over the entire region of the side edge of the belt member 60 in the extension direction D, a difference in the degree of ease of extension due to the presence or absence of the printed layer 67 does not occur, and cracks can be suppressed.

The print layer 67 may be disposed on the skin-facing surface side T1 of the base layer 66. Since the printed layer 67 is disposed on the skin-facing surface side T1 of the base layer 66, the printed layer 67 is not disposed toward the wearing article but is disposed toward the back sheet 22 when the absorbent article 10 is used. When the absorbent article 10 is used, the wearing article and the printed layer 67 are less likely to rub against each other, and the printed layer 67 is prevented from becoming unexpectedly hard to see.

The printed layer 67 may be configured to be visually recognizable from the non-skin-facing surface side of the absorbent article as being transmitted through the base layer 66. Preferably, the substrate layer 66 may be transparent or translucent. Since the base layer 66 is transparent or translucent, the printed layer 67 can be more easily visually recognized from the non-skin-facing surface side T2 of the absorbent article through the base layer 66.

In another embodiment, the printed layer 67 may be disposed on the non-skin-facing surface side T2 of the base layer 66. When the user visually confirms the absorbent article 10 from the non-skin-facing surface side T2 of the absorbent article, the printed layer 67 can be visually confirmed without interposing the base layer 66, and the recognition effect of the recognition area RA can be more easily exhibited.

The colored portion may be visually confirmed from the skin-facing surface side T1 of the absorbent article 10 so as to pass through the main body portion 20. When the absorbent article 10 is used, the skin-facing surface sheet 21 of the main body portion 20 faces the body of the wearer. Therefore, the user has many opportunities to visually confirm the skin-facing surface of the main body portion 20. Since the colored portion can be visually confirmed from the skin-facing surface side T1, the user can recognize the presence of the belt member 60 when wearing the garment.

The colored portion may be visually recognized as being transparent to the front sheet 21 and the back sheet 22 in a region where the absorbent core 23 is not disposed, and as being transparent to the front sheet 21, the back sheet 22, and the absorbent core 23 in a region where the absorbent core 23 is disposed. Preferably, the colored portion may be provided in a region not overlapping with the absorbent core 23. The skin-facing surface side T1 of the absorbent article 10 may be visually confirmed as being transmitted through the main body portion 20.

In addition, in the configuration in which the print layer 67 is disposed on the skin-facing surface side of the base layer 66 as in the present embodiment, the print layer 67 can be visually confirmed without interposing the base layer 66 when visually confirmed from the skin-facing surface side T1 of the absorbent article, and the presence of the belt member 60 can be more easily recognized when worn.

The identification region RA is provided over the entire area of the belt member 60 in a plan view, and is disposed in the grip portion 65. This makes the grip portion 65 more conspicuous to the region adjacent to the grip portion 65. The user can easily recognize the grip portion 65. The user can perform a smooth disposal operation by grasping the portion to be pinched at the time of the disposal operation.

More preferably, the grip portion 65 may be configured to be easily conspicuous with respect to an adjacent region adjacent to the one end 60A of the belt member 60 and an adjacent region adjacent to the side edge 60B of the belt member 60. The color difference with respect to the identification region RA may be Δ 3.0 or more in both the adjacent region adjacent to the one end 60A of the belt member 60 and the adjacent region adjacent to the side edge 60B of the belt member 60. Since the color difference Δ E between the grip portion 65 and 3 adjacent regions arranged so as to surround the grip portion 65 on the non-skin-facing surface of the main body portion 20 is 3.0 or more, the user can easily recognize the grip portion 65 and can perform a smooth disposal operation.

The identification region RA may be disposed at a position further outward in the front-rear direction than the outer edges of the adhesive portions 70, 42, 52 in the front-rear direction. Preferably, the identification region RA may be disposed at a position further outward in the front-rear direction than the outer end edge of the main body bonding portion 70 in the front-rear direction. The region provided with the adhesive portion is fixed to the wearing article during wearing, and is difficult to visually confirm from the skin-facing surface side of the absorbent article. On the other hand, the region on the outer side in the front-rear direction than the region where the adhesive portion is provided is not fixed to the wearing article when worn, and the absorbent article is rolled or floated, and thus the region may be visually recognized from the skin-facing surface side. Since the identification region is disposed at a position further outward in the front-rear direction than the outer end edge of the adhesive portion in the front-rear direction, the user can easily visually confirm the band member 60 when wearing the band member, and can easily identify the presence of the band member 60.

Next, an absorbent article according to another embodiment will be described. In the following description, the same reference numerals are used for the same portions as those of the above-described embodiment, and the description thereof is omitted. Fig. 5 shows a part of a plane viewed from the non-skin-facing surface side of the absorbent article 10A of modification 1 and the absorbent article 10B of modification 2. Fig. 5 (a) shows an absorbent article 10A according to modification 1, and fig. 5 (B) shows an absorbent article 10B according to modification 2.

The absorbent article 10A according to modification 1 and the absorbent article 10B according to modification 2 are configured such that the identification region RA is not disposed in the entire belt member, but is disposed in a part of the belt member 60. Specifically, the recognition area RA is disposed in the grip portion 65 of the belt member 60. When the user operates the band member 60, the user cannot grip the fixing portion 62 and operates it, but grips the grip portion 65. More preferably, the user operates the one end 60A (end opposite to the fixed portion) of the band member by holding it. The user can easily recognize the grip portion 65, and can smoothly grip the grip portion during operation, thereby cleanly disposing of the absorbent article using the belt member 60.

As a configuration for making the grip portion of the belt member more conspicuous, the belt-colored portion 92 may be provided only in the region where the grip portion 65 is disposed, as in the absorbent article 10A of modification 1. As in the absorbent article 10B of modification 2, the body colored portion 91 may be provided in the adjacent region RB adjacent to the grip portion 65, and the belt colored portion 92 may be provided in the region R3 of the belt member 60 other than the grip portion 65. In the absorbent article 10B of modification 2, the region R3 of the belt member 60 excluding the grip portion 65 may be less conspicuous to the non-skin-facing surface of the main body portion 20 and more conspicuous to the grip portion 65. Specifically, the color difference between the region R3 other than the grip portion of the belt member and the grip portion 65 (recognition region RA) may be higher than the color difference between the region R3 other than the grip portion of the belt member and the adjacent region RB. With such a configuration, the user can grasp not only the target member (belt member) to be operated, but also a portion of the target member to be operated. The user can smoothly perform the disposal operation by grasping the portion to be pinched at the time of the disposal operation.

Next, absorbent articles according to modifications 3 and 4 will be described with reference to fig. 6. Fig. 6 shows a part of a plane viewed from the non-skin facing surface side T2 of the absorbent article 10C of modification example 3 and the absorbent article 10D of modification example 4. Fig. 6 (a) shows an absorbent article 10C according to modification 3, and fig. 6 (B) shows an absorbent article 10D according to modification 4.

The absorbent article 10C according to modification 3 and the absorbent article 10D according to modification 4 are configured such that the identification region RA is not disposed in the entire belt member 60, but is disposed in a part of the belt member 60. The identification region RA is provided with a colored portion 92. The belt coloring portion 92 may have a guide portion 95 for guiding the operation of the belt member 60. The guide portion 95 may guide the operation of the belt member 60. Specifically, in the absorbent article used by pulling the belt member 60, an arrow indicating the direction of pulling may be used as in the absorbent article 10C of modification 3. In the absorbent article used in a state in which the belt member 60 is extended, the absorbent article may be configured to urge the user to perform an operation of stretching the belt member 60, as in the absorbent article 10D of modification 4, by a character of "extension" indicating that the belt member 60 has a property of being extended.

The colored portion may constitute only the guide portion 95, or may have a portion other than the guide portion 95. The coloring portion 92 of modification 4 may have a guide portion 95 and a background portion 96. By providing the guide portion 95 and the background portion 96, the guide portion 95 can be made more conspicuous, and smooth operation can be promoted. In such a configuration, the color difference between the guide section 95 and the adjacent region RB may be Δ 3.0 or more, or the color difference between the background section 96 and the adjacent region RB may be Δ 3.0 or more. In another embodiment, the body coloring portion 91 may have a guide portion.
