Technical Field

The present invention relates to a diaper for a low-weight infant.

Background

Conventionally, open-type disposable diapers have been widely used. With an open-type disposable diaper, both end portions of tape members (e.g., fastening tapes or straps) disposed on both left and right sides of a diaper main body (e.g., an absorbent main body) are locked to the front and rear sides of the diaper main body so as to wear the diaper. Patent document 1 discloses a disposable absorbent article of clothing (diaper) having a belt strip (belt member) provided with fasteners (locking members) that can be removably attached to a rear side and a front side.

Technical problem

According to the disposable diaper in patent document 1, the belt members can be attached and detached on the front and rear sides, thereby facilitating the operation of putting on and taking off the diaper. For example, when a parent wears such a diaper on an infant, the diaper can be easily worn or removed on the front or rear side regardless of whether the infant sleeps in a prone or supine position.

However, if a part of the locking member provided on the belt member is peeled off from the diaper main body while wearing the diaper, the disengaged part of the locking member may be hooked on and engaged with, for example, clothes or pads of an infant (on which they sleep), and the belt member may then be completely separated from the diaper main body. Particularly in the case where the diaper is used for a low-weight infant, it is required to minimize the movement of the body of the low-weight infant in order to reduce the burden on the body of the low-weight infant when the diaper is worn, and therefore, if the belt member is easily separated from the diaper main body, it is difficult to wear the diaper.

The present invention has been achieved in view of the conventional problems such as those described above, and it is an aspect of the present invention to provide a diaper for a low-weight infant, which suppresses separation of a belt member from a main body portion when worn.

A main aspect of the present invention for achieving the above-described aspect is a low-weight infant diaper having a longitudinal direction, a width direction, and a thickness direction intersecting each other,

the diaper for low-weight infants comprises:

an absorbent body comprising at least an absorbent core;

an exterior sheet disposed on a non-skin side with respect to the absorbent body; and

a pair of belt members each including one-side locking members on one side in a longitudinal direction of the belt member and another-side locking members on the other side in the longitudinal direction of the belt member,

in a state where each of the belt members is locked to the non-skin side of the exterior sheet in the thickness direction by the one-side locking member at a position located inward in the longitudinal direction with respect to the longitudinal outer end portion of the exterior sheet,

the outer end portion of the absorbent core is located inward in the longitudinal direction with respect to an intermediate position between the longitudinal outer end portion of the outer sheet and the outer end portion of the one-side locking member.

Features of the present invention other than those described above will become apparent by reading the description of the present specification with reference to the accompanying drawings.

Advantageous effects of the invention

According to the present invention, it is possible to provide a diaper for a low-weight infant, which suppresses separation of the belt member from the main body portion when the diaper is worn.

Detailed Description

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

A low-weight infant diaper having a longitudinal direction, a width direction and a thickness direction intersecting each other,

the diaper for low-weight infants comprises:

an absorbent body comprising at least an absorbent core;

an exterior sheet disposed on a non-skin side with respect to the absorbent body; and

a pair of belt members each including one-side locking members on one side in a longitudinal direction of the belt member and another-side locking members on the other side in the longitudinal direction of the belt member,

in a state where each of the belt members is locked to the non-skin side of the exterior sheet in the thickness direction by the one-side locking member at a position located inward in the longitudinal direction with respect to the longitudinal outer end portion of the exterior sheet,

the outer end portion of the absorbent core is located inward in the longitudinal direction with respect to an intermediate position between the longitudinal outer end portion of the outer sheet and the outer end portion of the one-side locking member.

According to this diaper for low-weight infants, when the diaper is put on a low-weight infant, the portion of the outer sheet folded at a predetermined longitudinal position of the diaper covers the non-skin side of the outer end portion of the one-side locking member (inner locking member). This makes the one-side locking member less likely to be peeled off from the back sheet (main body portion). Therefore, this suppresses the belt member from being separated from the main body portion when the diaper is worn.

In such a diaper for a low-weight infant, it is desirable that,

the absorbent body includes a core wrap sheet covering the absorbent core, and

the outer end portion of the core wrap piece is located inward in the longitudinal direction with respect to the intermediate position, which is a position between the longitudinal outer end portion of the exterior piece and the outer end portion of the one-side locking member.

According to this diaper for low-weight infants, when the diaper is put on a low-weight infant, even if the outer sheet is folded at the outer end of the core wrap sheet, the longitudinal outer end of the one-side locking member (inner locking member) is covered on the non-skin side. This makes the one-side locking member less likely to be peeled off from the back sheet (main body portion). Therefore, this suppresses the belt member from being separated from the main body portion when the diaper is worn.

In such a diaper for a low-weight infant, it is desirable that,

the longitudinal outer end portion of the absorbent core is located between the outer end portion of the one-side locking member and the intermediate position in the longitudinal direction, the intermediate position being a position between the outer end portion of the outer sheet and the outer end portion of the one-side locking member.

According to this diaper for low-weight infants, when the diaper is worn on a low-weight infant, there is a possibility that the outer covering sheet is folded at the longitudinal outer end portion of the absorbent core (or the core-wrapping sheet). The folded position of the exterior sheet can be adjusted, thus making it easier for the longitudinal outer end portion of the one-side locking member (inner locking member) to be covered. Therefore, this helps to suppress the belt member from being separated from the main body portion when the diaper is worn.

In such a diaper for a low-weight infant, it is desirable that,

the outer end portion of the absorbent core is located inward in the longitudinal direction with respect to the outer end portion of the one-side locking member.

According to this diaper for low-weight infants, the outer sheet is easily folded at the longitudinal outer end portion of the one-side locking member (inner locking member). The folded position of the exterior sheet can be adjusted, thus making it easier for the longitudinal outer end portion of the one-side locking member (inner locking member) to be covered. Therefore, this helps to suppress the belt member from being separated from the main body portion when the diaper is worn.

In such a diaper for a low-weight infant, it is desirable that,

the diaper for low-weight infants further comprises leg elastic members capable of stretching and contracting in the longitudinal direction, and

the one-side locking member does not overlap with a region in which the leg elastic member has stretchability in the longitudinal direction.

According to this low-weight infant diaper, in the region where the one-side locking member (inner locking member) is locked, the contraction force of the leg elastic member is less likely to act on the exterior sheet, and bending and wrinkling of the exterior sheet in such region are suppressed. Therefore, the one-side locking member is securely locked to the exterior sheet, and further, it is easy to suppress the separation of the band member from the main body portion.

In such a diaper for a low-weight infant, it is desirable that,

the one-side locking member does not overlap with the outer end portion of the absorbent main body in the width direction.

According to this low-weight infant diaper, the locking position of the one-side locking member (inner locking member) does not intersect with the portion in which there is a large height difference at the widthwise outer end portion of the absorbent main body, thus making it possible to suppress a situation in which the locking member is easily peeled off at such a portion. Therefore, it is further easy to suppress the separation of the belt member from the main body portion.

In such a diaper for a low-weight infant, it is desirable that,

the inner end portion of the one-side locking member is located outside in the width direction with respect to the outer end portion of the absorbent main body.

According to this diaper for low-weight infants, the one-side locking member (inner locking member) does not overlap with the absorbent main body. Therefore, when the diaper is inserted between the body of the infant and the pad in order to put the diaper on the low-weight infant, the one-side locking member is suppressed from being pressed against the pad by the rigid absorbent body. Therefore, this contributes to suppressing the one-side locking member from being peeled off from the exterior sheet.

In such a diaper for a low-weight infant, it is desirable that,

the sum of the thickness of each of the belt members and the thickness of the one-side locking member is smaller than the thickness of the absorbent main body.

According to the diaper for a low-weight infant, a space is formed between the body of the low-weight infant and the pad according to the thickness of the absorbent body when the diaper is worn, and the belt member and the one-side locking member are easily put into the space. Therefore, friction is not easily generated between the belt member and the cushion, and the one-side locking member (inner locking member) is easily suppressed from being peeled off from the exterior sheet.

In such a diaper for a low-weight infant, it is desirable that,

the low-weight infant diaper further includes leg elastic members capable of stretching and contracting in the longitudinal direction,

a widthwise distance between the outermost leg elastic member and a widthwise outer end portion of the exterior sheet is smaller than a width of the one-side locking member, an

The width-direction inner end portion of the one-side locking member is located inward in the width direction with respect to the outermost leg elastic member.

According to this diaper for low-weight infants, the one-side locking member (inner locking member) is less likely to protrude beyond the outermost outer end portion of the outer sheet. Therefore, the inner locking member is not easily brought into contact with the skin of a low-weight infant, and a situation that causes the low-weight infant to feel discomfort can be suppressed.

In such a diaper for a low-weight infant, it is desirable that,

the low-weight infant diaper further includes a pair of leakage preventing walls on respective widthwise sides of the absorbent main body,

each of the leakage preventing walls includes an LSG elastic member capable of stretching and contracting in the longitudinal direction, and

the one-side locking member is located outside in the width direction with respect to the LSG elastic member in a state where the low-weight infant diaper has been unfolded and stretched.

According to this low-weight infant diaper, the one-side locking member (inner locking member) is inhibited from being locked at a position too far inward in the width direction. Therefore, when the diaper is worn on a low-weight infant, it is possible to suppress the occurrence of problems such as the longitudinal length of the belt member being insufficient and the other-side locking member (outer locking member) not being locked to the outer sheet.
