<Embodiment 1>
A diaper according to Embodiment 1 of the present invention will be described below with reference to the drawings. The configurations of the following embodiments are examples, and the present invention is not limited to the configurations of these embodiments.

FIG. 1 is a perspective view of an adult underpants-type disposable diaper (hereinafter simply referred to as "diaper") according to the embodiment. In the diaper, the longitudinal direction is the direction connecting the front body arranged to face the abdomen of the wearer and the back body arranged to face the back of the wearer. Between the front body (one side in the longitudinal direction) and the back body (the other side in the longitudinal direction) (center in the longitudinal direction), there is an inseam that is placed in the wearer's crotch (placed facing the crotch) department is located. In addition, when the diaper is worn by the wearer, the side facing the wearer's skin is the skin side, and the side opposite to the skin side is the non-skin side. Furthermore, the direction connecting the skin surface side and the non-skin surface side is defined as the thickness direction, and the direction orthogonal to both the longitudinal direction and the thickness direction is defined as the width direction. In addition, viewing from the thickness direction is defined as planar view. The diaper 1 has a length along the longitudinal direction and a lateral width along the width direction orthogonal to the longitudinal direction, and is worn around the wearer's crotch. In addition, the terms used in the present application regarding directions mean directions corresponding to the front, back, left, and right of the wearer when the diaper 1 is worn by the wearer. For example, in the present application, the lateral direction means a direction corresponding to the lateral direction of the wearer when the diaper 1 is worn by the wearer.

In the present embodiment, as an example of an absorbent article, a pants-type disposable diaper having a cylindrical structure having an opening for receiving the wearer's abdominal circumference and a pair of left and right openings through which the wearer's left lower leg and right lower leg are inserted. However, the "absorbent article" in the present application is not limited to pants-type disposable diapers for adults. As used herein, "absorbent articles" include pants-type disposable diapers for children. In addition, a tape fixed near one end of a sheet-shaped member that covers the wearer's crotch (genitals) from the front body to the back body is attached near the other end of the sheet-shaped member to form a cylindrical structure. Included are various forms of absorbent articles that can wrap around the waist and crotch, such as tape-type disposable diapers that form a .

The diaper 1 has a crotch region 1B, which corresponds to the crotch covering the pubic region (crotch) of the wearer when worn, and a region corresponding to the front body around the waist of the wearer, which is the abdominal side of the wearer. It has a front body region 1F for covering and a back body region 1R for covering the wearer's back side, which is a part corresponding to the back body around the waist of the wearer. Here, the front body region 1F is located on the front side of the crotch region 1B, and the back body region 1R is located on the rear side of the crotch region 1B. The diaper 1 in this embodiment is a pants-type disposable diaper, and the front body region 1F and the back body region 1R of the outer sheet are separated from each other in the width direction so as to form a waist portion 2D having a waist opening 2T. side seal portions SL and SR for joining the The left edge of the front body region 1F and the left edge of the back body region 1R are joined together by the side seal portion SL, and the right edge of the front body region 1F and the right edge of the back body region 1R are joined by the side seal portion SR. are joined together. Therefore, in the diaper 1, the upper edge of the front body region 1F and the upper edge of the back body region 1R form a waist opening 2T (an example of the "waist opening" of the present disclosure). In the diaper 1, a left leg opening 2L is formed on the left side of the crotch region 1B, which is not joined, and a right lower leg opening 2R is formed on the right side of the crotch region 1B. In the diaper 1, the wearer's left lower leg is inserted through the left lower leg opening 2L, the wearer's right lower leg is inserted through the right lower leg opening 2R, and the wearer's trunk is inserted through the trunk opening 2T. When worn, the front body region 1F is arranged on the abdomen side of the wearer, the back body region 1R is arranged on the back side of the wearer, and the left lower leg opening 2L and the right lower leg opening 2R are arranged on the wearer's thighs. It is fixed to the wearer's body in a state surrounding the part. Since the diaper 1 is fixed to the wearer's body in this manner, the wearer can move freely while wearing the diaper 1 .

In the diaper 1, an absorbent body capable of absorbing and retaining liquid is mainly arranged around the crotch region 1B. In addition, the diaper 1 has a left lower leg opening surrounding the thigh of the wearer's left lower leg in order to suppress formation of a gap serving as an outflow path for liquid between the diaper 1 and the wearer's skin. Three-dimensional gathers 3BL are provided in 2L, three-dimensional gathers 3BR are provided in the lower right leg opening 2R surrounding the thigh of the wearer's right leg, and waist gathers 3R are provided in the waist section 2D surrounding the waist circumference of the wearer. there is In addition, leg gathers 3LL and 3LR are provided at positions surrounding the roots of the wearer's legs. The three-dimensional gathers 3BL, 3BR and the waist gathers 3R are in close contact with the wearer's skin due to the elastic force of the thread rubber. Also, the leg gathers 3LL and 3LR prevent a gap from being created between the groin of the wearer's leg and the diaper 1.例文帳に追加Therefore, the excrement discharged from the wearer's pubic region is absorbed by the absorber of the diaper 1 without hardly leaking out of the diaper 1 .

The diaper 1 can be used in combination with an inner pad (not shown). The inner pad is a generally rectangular absorbent article with an absorbent body to absorb exuded liquids. When the diaper 1 and the inner pad are used in combination, the inner pad is placed on the skin surface side of the diaper 1 so as to be in contact with the discharge holes of the wearer. The discharged liquid is first absorbed by the inner pad, and only the discharged liquid that could not be absorbed by the inner pad reaches the absorber of the diaper 1 and is further absorbed. Therefore, even when the amount of discharged liquid is large, leakage of the discharged liquid from the diaper 1 can be prevented. In addition, when the amount of discharged liquid is small and can be completely absorbed by the inner pad, only the inner pad needs to be replaced even if the discharged liquid is generated, which reduces the assistance cost. Moreover, the diaper 1 can be used for a long time.

FIG. 2 is an exploded perspective view of the diaper 1 according to Embodiment 1. FIG. The diaper 1 has a cover sheet 4 (an example of the “outer cover sheet” referred to in the present application) and an inner cover sheet 5 .
The cover sheet 4 and the inner cover sheet 5 are substantially hourglass-shaped (gourd-shaped) sheets that are bonded together to form the outer surface of the diaper 1, and have an end on the front body region 1F side and an end on the back body region 1R side. Other than that, they have the same shape. When worn by the wearer, the cover sheet 4 is laminated on the non-skin side of the wearer, and the inner cover sheet 5 is laminated on the skin side. Thread rubbers are provided between the cover sheet 4 and the inner cover sheet 5 to form the waist gathers 3R and the leg gathers 3LL and 3LR. It should be noted that a stretchable member such as belt-like rubber can be appropriately selected instead of the thread rubber.

The cover sheet 4 and the inner cover sheet 5 can be made of, for example, a non-woven fabric made of a liquid-impermeable thermoplastic resin, in order to suppress leakage of discharged matter. Examples of liquid-impermeable thermoplastic resins include polyethylene (PE) and polypropylene (PP).

The diaper 1 has a back sheet 6, an absorbent body 8, and a top sheet 9 which are laminated in order on the wearer-side surfaces of the cover sheet 4 and the inner cover sheet 5. As shown in FIG. The back sheet 6 is a substantially rectangular sheet having a length extending from the wearer's front body to the back body via the crotch in the longitudinal direction and having a predetermined width in the width direction orthogonal to the longitudinal direction. . Both the absorbent body 8 and the top sheet 9 are sheet-like members having a substantially rectangular appearance like the back sheet 6 . are stacked in order. The back sheet 6 is a sheet made of a liquid-impermeable thermoplastic resin in order to suppress leakage of discharged matter. Moreover, the top sheet 9 is a sheet-like member arranged on the wearer's skin surface side so as to cover the absorbent surface of the absorbent body 8 . This top sheet 9 has liquid permeability in part or in its entirety. Therefore, in the state in which the diaper 1 is worn, the liquid discharged from the wearer passes through the topsheet 9, which may come into contact with the wearer's skin, and enters the absorbent body 8, where it is absorbed. Examples of liquid-permeable sheets include woven fabrics, non-woven fabrics, and porous films. Moreover, the top sheet 9 may have hydrophilicity.

The absorbent body 8 has an absorbent core 8c made of one mat and a core wrap sheet 7 (an example of the "water-permeable sheet" of the present disclosure) that wraps the absorbent core 8c. The absorbent core 8c has a substantially hourglass shape with a constricted portion. The absorbent core 8c contains short fibers of cellulose fibers such as pulp fibers, rayon fibers, or cotton fibers, or short fibers obtained by hydrophilizing synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate. It has a structure in which a granular absorbent resin (polymeric absorbent) such as SAP (Super Absorbent Polymer), which is a hydrophilic polymer having a crosslinked structure capable of absorbing and holding the , is held. When the absorbent core 8c absorbs the liquid discharged from the wearer, it swells the absorbent resin held in the gaps in the short fibers and holds the liquid in the short fibers. In this embodiment, the absorbent core 8c has a substantially hourglass shape constricted near the center. The absorbent core 8c can have an appropriate shape according to the purpose. Examples of the shape of the absorbent core 8c include a rectangular shape, an elliptical shape, and various other shapes.

The core wrap sheet 7 is a thin liquid-permeable sheet, and by wrapping the absorbent core 8c with the core wrap sheet 7, the SAP of the absorbent core 8c described above is less likely to mix with other structures. Also, the shape loss of the absorbent core 8c is suppressed. The core wrap sheet 7 can be made of pulp fibers, and tissue paper can be used as an example. Although the core wrap sheet 7 may be a single sheet, it consists of an upper sheet arranged on the wearer's skin side and a lower sheet arranged on the wearer's non-skin side and wrapping around the sides and the skin side of the absorbent core. It may be composed of two sheets of side sheets. When the core wrap sheet 7 is composed of two sheets, the width direction end of the upper sheet is wrapped by other sheets (for example, the side sheets 10L and 10R, the back sheet 6, and the top sheet 9, which will be described later). can be Note that the absorbent body 8 is wrapped by the back sheet 6 and the top sheet 9, and these sheets can also prevent the absorbent body from losing its shape, so the core wrap sheet 7 can be omitted.

The backsheet 6, absorbent body 8, and topsheet 9 all extend from the front body region 1F to the back body region 1R. Therefore, when the back sheet 6, the absorbent body 8, and the top sheet 9 are laminated to cover the pubic region (crotch) of the wearer, both longitudinal ends of the back sheet 6, the absorbent body 8, and the top sheet 9 can be It is positioned on the ventral and dorsal sides of the In other words, the wearer's pubic region is covered with the absorber 8 from the wearer's ventral side to the dorsal side. Therefore, regardless of whether the wearer discharges the liquid to the outside of the body with the stomach facing downward or the posture with the back facing downward, the discharged liquid comes into contact with the absorbent body 8 via the top sheet 9 . will do.

The diaper 1 also has elongated band-like side sheets 10L and 10R for forming the three-dimensional gathers 3BL and 3BR described above. The side sheets 10L and 10R are provided on the long sides of the top sheet 9. As shown in FIG. Thread rubbers 10L1 and 10R1 are adhered to the side sheets 10L and 10R along the longitudinal direction. Therefore, the edge 4F4 of the cover sheet 4, which is the left edge of the front body region 1F, and the edge 4R4, which is the left edge of the back body region 1R, are joined together, and the cover sheet 4 is joined to the front body region 1F. When the diaper 1 in the completed state as shown in FIG. 10R is drawn in the longitudinal direction by the contractile force of the rubber threads 10L1 and 10R1, and rises from the top sheet 9 along folding lines 10L2 and 10R2 (an example of "raising lines"). As a result, three-dimensional gathers 3BL and 3BR are formed to prevent liquid from flowing out from the left leg opening 2L and the right lower leg opening 2R (details will be described later). Although the method of joining the edges 4F4 and 4R4 and the edges 4F5 and 4R5 is not particularly limited, for example, heat sealing, high-frequency sealing, ultrasonic sealing, or the like can be used.

Furthermore, the diaper 1 further includes an end sheet 11F laminated on the wearer-side surface of the front body region 1F of the cover sheet 4 with the back sheet 6, the absorbent body 8, the top sheet 9, and the side sheets 10L and 10R interposed therebetween; and an end sheet 11R laminated on the wearer-side surface of the back body region 1R of the cover sheet 4. As shown in FIG. The end sheets 11</b>F and 11</b>R are strip-shaped sheets that are overlapped with the cover sheet 4 and the inner cover sheet 5 at one end side of the top sheet 9 in the longitudinal direction. The end sheets 11F and 11R are made of water-impermeable non-woven fabric, and mainly reinforce the cover sheet 4 and the inner cover sheet 5 at the waist contact portion of the diaper 1 . Adhesive is applied to each of the end sheets 11F and 11R, and the end sheets 11F and 11R are adhered to the inner cover sheet 5 by the adhesive. The end sheets 11F and 11R are arranged closer to the skin than the laminate formed by the back sheet 6, the absorbent body 8, the top sheet 9 and the side sheets 10L and 10R, and the edges of the laminate are in direct contact with the skin when worn. prevent people from feeling uncomfortable.

FIG. 3 is a diagram schematically showing the state in which the diaper 1 according to Embodiment 1 is unfolded and stretched. FIG. 3(A) schematically shows the internal structure of the diaper 1 in the unfolded and stretched state when viewed from the left side. FIG. 3(B) is a plan view of the diaper 1 in an unfolded and stretched state. Note that the side seats 10L and 10R and the end seats 11F and 11R are not shown in FIG. 3(B). One end side of the cover sheet 4 is folded at folding lines 4FF and 4RF shown in FIG. The waist gathers 3R described above have rubber threads (rubber threads) 4F1 and 4F2 bonded to the front body region of the cover sheet 4, and rubber threads (rubber threads) 4R1 and 4R2 bonded to the back body region of the cover sheet 4. formed by The rubber threads 4F1 and 4F2 are provided in this order from the side of the folding line 4FF along the folding line 4FF that forms the upper edge of the front body region 1F when folded back. Similarly to the rubber threads 4F1 and 4F2, the rubber threads 4R1 and 4R2 are also stretched from the side of the folding line 4RF along the folding line 4RF that forms the upper edge of the back body region 1R when folded back. are provided in the order of

Therefore, the rubber threads 4F1 and 4F2 are provided on the cover sheet 4 in such a direction that the longitudinal direction, which is the stretching direction, is the left-right direction of the diaper 1 . Also, the rubber threads 4R1 and 4R2 are provided on the cover sheet 4 in such a direction that the longitudinal direction, which is the stretching direction, is the left-right direction of the diaper 1. As shown in FIG. Therefore, when the edge 4F4 and the edge 4R4 are joined to each other, and the edge 4F5 and the edge 4R5 are joined to each other, the rubber threads 4F1 and 4F2 and the rubber threads 4R1 and 4R2 are formed substantially in an annular shape around the trunk opening 2T. , and exerts the function of contracting the waist opening 2T in the waist circumference direction. That is, the rubber threads 4F1, 4F2 and the rubber threads 4R1, 4R2 exert a contractile force to bring the diaper 1 into close contact with the wearer, thereby preventing formation of a gap between the diaper 1 and the wearer's waist circumference. A portion of the plurality of rubber threads 4F2 and 4R2 on the side of the crotch region 1B overlaps the absorber 8. As shown in FIG.

The thread rubbers 4F1 and 4R1 are provided so as to extend in the left-right direction along the upper edges of the front body region 1F and the back body region 1R shown in FIG. The thread rubbers 4F2 and 4R2 are provided in parallel with a predetermined interval. When the diaper 1 is worn, the rubber threads 4F1 and 4R1 tighten the waist circumference of the wearer above the rubber threads 4F2 and 4R2 relatively strongly. The thread rubbers 4F1 and 4R1 have the function of keeping the diaper 1 in close contact with the wearer to prevent the wearer from slipping out of position and preventing discharge from leaking from the abdomen and back. The rubber threads 4F2 and 4R2 relieve the wearer's feeling of pressure caused by the contractile force of the rubber threads 4F1 and 4R1. Moreover, when an inner pad is used, displacement of the inner pad is suppressed.

Furthermore, a rubber thread 4F3 and a rubber thread 4R3 are adhered to the cover sheet 4. As shown in FIG. The rubber thread 4F3 and the rubber thread 4R3 are elastic members provided in the region of the cover sheet 4 closer to the crotch region 1B than the rubber thread 4F2 and 4R2. The rubber thread 4F3 is provided so as to traverse in the left-right direction on the front body region 1F side. In the region where the rubber thread 4F3 is provided so as to traverse in the left-right direction, the rubber thread 4F3 and the absorbent body 8 overlap each other in the thickness direction of the diaper 1 . Moreover, the width direction center part of such a crossing area|region becomes an area|region corresponding to a female wearer's urethral opening when the diaper 1 is worn. In addition, in the area|region where the absorber 8 has overlapped seen in the thickness direction, the arrangement form of the rubber thread 4F3 is not limited to crossing as shown in FIG. It is sufficient that the extending direction of the rubber thread 4F3 has a component in the width direction, and preferably the width component in the extending direction of the rubber thread 4F3 is larger than the longitudinal component. The rubber thread 4R3 is different from other rubber threads that are adhered from the left end to the right end of the cover sheet 4 without interruption, and is arranged in a curved manner toward the crotch region 1B. It overlaps with part of the absorbent core 8c. By configuring in this way, it is possible to cause the arrangement regions of the rubber threads 4F3 and 4R3 to function as leg gathers.

The cover sheet 4 is folded back along folding lines 4FF and 4RF to extend to the arrangement area of the rubber thread 4F1 and the rubber thread 4R1, and the folded part reinforces the arrangement area of the rubber thread 4F1 and the rubber thread 4R1. . The end sheets 11F, 11R are provided in areas where the rubber threads 4F2, 4R2 are arranged, where the cover sheet 4 folded back at the folding lines 4FF, 4RF does not extend, and reinforces the areas where the rubber threads 4F2, 4R2 are arranged. ing.

In the present application, the state in which the sheets are overlapped is not limited to the state in which the sheets are entirely in contact with each other, but includes the concept in which the sheets partially overlap each other. For example, the end sheet 11</b>F is overlapped in such a manner that a portion of the back sheet 6 on one end side in the longitudinal direction touches a portion of the cover sheet 4 . Since the diaper 1 is formed by stacking the back sheet 6 and the top sheet 9 with the absorbent body 8 sandwiched therebetween, the cover sheet 4, the end sheets 11F and 11R, the inner cover sheet 5, and the side sheets 10L and 10R are stacked. , it can be said to have a laminate in which a plurality of these sheets are stacked.

Next, with reference to FIG. 4, the adhesion form of the exterior sheet of the diaper 1 according to the embodiment will be described. FIG. 4 is a diagram schematically showing the state in which the diaper 1 according to Embodiment 1 is unfolded and stretched. The diaper 1 has, as exterior sheets, a cover sheet 4 forming an exterior surface and an inner cover sheet 5 laminated on the skin surface side of the cover sheet 4 . The cover sheet 4 and the inner cover sheet 5 are bonded together at a plurality of bonding portions.

Specifically, a plurality of linear bonding portions 5L for bonding the cover sheet 4 and the inner cover sheet 5 are provided in the crotch region 1B. A plurality of linear bonded portions L5 are intermittently provided in the longitudinal direction of the diaper 1. As shown in FIG. In other words, each of the plurality of linear bonded portions L5 are separated from each other in the longitudinal direction. The plurality of linear bonded portions L5 extend to the ends in the width direction. The linear bonded portion L5 is formed by applying a hot-melt adhesive.

Also, the cover sheet 4 and the inner cover sheet 5 are bonded together by a plurality of bonding portions 40F, 40R, 41F, 41R, 42F, and 42R extending along the width direction of the diaper 1 . These adhesive portions are formed by hot-melt adhesive. A plurality of adhesive portions 40F are formed so as to be spaced apart from each other. A plurality of bonding portions 40F are formed along each of the plurality of rubber threads 4F1, and the rubber threads 4F1 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 40F. A plurality of adhesive portions 40R are formed to be spaced apart from each other. A plurality of bonding portions 40R are formed along each of the plurality of rubber threads 4R1, and the rubber threads 4R1 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 40R. A plurality of adhesive portions 40F are formed so as to be spaced apart from each other. The thread rubbers 4F1 and 4R1 are adhered to the cover sheet 4 and the inner cover sheet 5 in a stretched state, and form an annular elastic portion extending along the width direction of the diaper 1 at the waist portion 2D.

Moreover, the adhesion part 41F is spaced apart mutually, and is formed in multiple numbers. A plurality of bonding portions 41F are formed along each of the plurality of rubber threads 4F2, and the rubber threads 4F2 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 41F. A plurality of adhesive portions 41R are formed so as to be spaced apart from each other. A plurality of bonding portions 41R are formed along each of the plurality of rubber threads 4R2, and the rubber threads 4R2 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 41R. The thread rubbers 4F2 and 4R2 are adhered to the cover sheet 4 and the inner cover sheet 5 in a stretched state, forming an annular elastic portion extending along the width direction of the diaper 1 at the waist portion 2D. In the diaper 1, the waist gathers 3R shown in FIG. 1 are formed by adhering the rubber threads 4F1, 4R1, 4F2, 4R2 in a stretched state to the cover sheet 4 and the inner cover sheet 5 in the waist portion 2D.

A plurality of adhesive portions 42F are formed so as to be spaced apart from each other. The bonding portion 42F bonds the cover sheet 4 and the inner cover sheet 5 on the crotch region 1B side of the rubber thread 4F2. A plurality of adhesive portions 42R are formed so as to be spaced apart from each other. The bonding portion 42R bonds the cover sheet 4 and the inner cover sheet 5 on the crotch region 1B side of the rubber thread 4FR. The adhesive portion 42F is arranged closer to the front body region 1F than the linear adhesive portion 5L, and the adhesive portion 42R is arranged closer to the back body region 1R than the linear adhesive portion 5L. The bonding portions 42</b>F and 42</b>R bond the cover sheet 4 and the inner cover sheet 5 in areas where the rubber thread is not arranged between the cover sheet 4 and the inner cover sheet 5 .

In addition, in this embodiment, the absorbent core 8c has a shape constricted in the width direction at the center of the diaper 1 in the longitudinal direction. A region where the absorbent core 8c is constricted in the width direction is a region corresponding to the wearer's crotch and is a crotch region 1B. In addition, the widthwise end of the diaper 1 in the crotch region 1B extends along the longitudinal direction.

In the present embodiment, since the crotch region 1B is provided with a plurality of linear adhesive portions L5, the amount of hot-melt adhesive applied to the crotch region 1B is relatively small, and the cover sheet 4 and the inner cover sheet 5 are bonded together. The exterior sheet of the can be made flexible. In the diaper 1, the width direction end portions of the outer body, which are most likely to bite into the wearer's skin when worn, are softened by providing a plurality of linear adhesive portions L5 at the width direction end portions, thereby providing a feeling of wearing in the crotch region 1B. can suppress the decrease in

The adhesive portions 40F, 40R, 41F, 41R, 42F, and 42R linearly extend parallel to each other along the width direction of the diaper 1 . Hereinafter, the bonding portions 40F, 40R, 41F, 41R, 42F, and 42R may be collectively referred to as the second linear bonding portion 40F or the like. In order to bond the thread rubbers 4F1, 4F2, 4R1 and 4R2, it is preferable that the bonded portions extend along the width direction. In addition, in order to make the feel of the waist part 2D and other parts uniform, a second linear bonding part 40F or the like extending in the width direction is provided over the entire exterior sheet.

If the cover sheet 4 and the inner cover sheet 5 are adhered over the entire area, a hot-melt adhesive is used for the adhesion, resulting in poor contact with the wearer's skin. The diaper 1 according to this embodiment includes the second linear bonding portions 40F and the like for bonding the cover sheet 4 and the inner cover sheet 5, so that the cover sheet 4 and the inner cover sheet 4 are separated from the inner cover sheet 40F and the like between the second linear bonding portions 40F and the like. The cover sheet 5 is made non-adhesive to prevent the wearer from feeling poor against the skin. Thereby, the diaper 1 which concerns on this embodiment can suppress the fall of a wearing feeling.

In addition, if the shape of the adhesive portion and the extension direction of the adhesive portion differ for each region of the diaper 1, for example, the regions where the rubber threads 4F1 and 4R1 are arranged, and the regions where the rubber threads 4F2 and 4R2 are arranged, the outer sheet may be deformed. The wrinkles are formed differently in each area, and the appearance of the diaper is deteriorated. On the other hand, in the diaper 1 according to the present embodiment, since the extension direction of the second linear bonded portions 40F and the like is the same in all regions, the wrinkles of the outer sheet are uniform in each region, and the appearance is improved. is not lost.

Further, when the diaper 1 is partitioned into a plurality of regions in the longitudinal direction, the intervals between the second linear adhesive portions 40F and the like are the same in each region. For example, the diaper 1 has a region in which the rubber threads 4F1 and 4R1 are arranged (eg, an example of a "first region") and a region in which the rubber threads 4F2 and 4R2 are arranged (eg, an example of a "second region"). ), a region on the crotch side of the region where the rubber threads 4F2 and 4R2 are arranged (for example, an example of a “third region”). The first area is an area close to the trunk opening edge forming the trunk opening 2T shown in FIG. 1, and is an area where the rubber threads 4F1 and 4R1 are arranged. The second region is adjacent to the first region on the side of the crotch region 1B, and is a region where the thread rubbers 4F2 and 4R2 are arranged. The third region is adjacent to the second region on the crotch region 1B side, and is a region where no stretchable member such as rubber thread is arranged between the cover sheet 4 and the inner cover sheet 5 except for the crotch region 1B. .

In the regions where the rubber threads 4F1 and 4R1 are arranged, the intervals between the plurality of bonding portions 40F and 40R are the same. In other words, the plurality of rubber threads 4F1 and 4R1 are arranged at the same intervals. Also, in the regions where the rubber threads 4F2 and 4R2 are arranged, the intervals between the plurality of bonding portions 41F and 41R are the same. In other words, the plurality of rubber threads 4F2 and 4R2 are arranged at the same intervals. Also, in the area on the crotch side of the area where the rubber threads 4F2 and 4R2 are arranged, the intervals between the plurality of bonding portions 42F and 42R are the same. In the diaper 1, since the adhesive force required for design differs in each area, by making the distance between the second linear adhesive portions 40F and the like uniform for each area, the change in the feel and appearance as a whole can be made uniform. ,
In addition, it prevents the adhesive force from becoming excessive or insufficient in each region.

Further, the distance between the bonded portions 42F, 42R in the region on the crotch side of the region where the rubber threads 4F2, 4R2 are arranged is the distance between the bonded portions 40F, 40R in the region where the rubber threads 4F1, 4R1 are arranged. Wider and less than twice as large. Similarly, the distance between the bonding portions 42F and 42R in the region on the crotch side of the region where the rubber threads 4F2 and 4R2 are arranged is the distance between the bonding portions 41F and 41R in the region where the rubber threads 4F2 and 4R2 are arranged. It is wider than the interval and not more than twice as large. In summary, the distance between the bonded portions 42L and 42R in the regions where the rubber threads are not arranged is the distance between the bonded portions 40F and 40R in the regions where the rubber threads 4F1 and 4R1 and the rubber threads 4F2 and 4R2 are arranged. It is wider than the interval between the portions 41F and 41R and not more than twice as large. The area where the rubber threads 4F1, 4R1 and the rubber threads 4F2, 4R2 are arranged is the waist part 2D, and waist gathers are formed in the waist part 2D. The feel and appearance of the waist portion 2D are caused by the waist gathers, but the feel and appearance of the area where the gathers are not formed are caused by the bonding portions 42F and 42R. Therefore, the difference between the interval between the bonding portions 42F and 42R in the region where the gathers are not formed and the interval between the bonding portions 40F, 40R, 41F and 41R in the region where the waist gathers are formed is set to twice or less. Thus, the diaper 1 can reduce differences in feel and appearance between regions.

As described above, the distance between the bonding portions 42F, 42R in the region on the crotch side of the region where the rubber threads 4F2, 4R2 are arranged is It is wider than the interval between 41R and not more than two times. Breathability is especially required on the crotch side. By reducing the areas of the adhesive portions 41F and 41R, the diaper 1 can reduce the non-breathable adhesive portions and obtain necessary breathability.

In addition, since the crotch region 1B of the diaper 1 is sandwiched between the wearer's thighs, the end portions of the exterior sheet bite into the thighs of the wearer in the crotch region 1B. On the other hand, the front body region 1F of the diaper 1 is in a state along the wearer's abdomen, and the back body region 1R of the diaper 1 is in a state along the wearer's buttocks and back, the front body region 1F and the back body region 1R. , the exterior sheet does not dig into the wearer's skin. Therefore, in the crotch region 1B, if the entire surface of the outer sheet, particularly the widthwise end portion, of the exterior sheet is adhered, the end portion becomes hard and the contact with the skin is poor. By spacing them apart from each other, it is possible to soften the skin contact.

In addition, the cover sheet 4 and the inner cover sheet 5 are arranged adjacent to the adhesive portions 42L and 42R at the end portions in the width direction of the diaper 1, and the cover sheet 4 and the cover sheet 4 are arranged on the width direction extension line between the adhesive portions 42L and 42R. It has full-surface bonded portions 43FL, 43FR, 43RL, and 43RR to which the inner cover sheet 5 is bonded. The full-surface adhesive portions 43FL, 43FR, 43RL, and 43RR are formed by applying a hot-melt adhesive to the entire formation regions thereof. The full-surface bonded portions 43FL, 43FR, 43RL, and 43RR are arranged adjacent to the front body region 1F side and the back body region 1R side of the linear bonded portion 5L on the width direction end side of the exterior sheet, and are arranged adjacent to the front body region 1F side and the back body region 1R side of the outer sheet. This is the area where the cover sheet 5 is entirely adhered. The crotch region 1B is located between the full-surface adhesive portions 43FL and 43RL on the left side of the diaper 1, and the crotch region 1B is located between the full-surface adhesive portions 43FR and 43RR on the right side of the diaper 1. Note that the full-surface adhesive portions 43FL and 43FR are integrally formed to be connected at the center in the width direction. In this way, the crotch region 1B is sandwiched between the full-surface adhesive portions when the diaper 1 is viewed in the longitudinal direction, so that the full-surface adhesive portions 43FL, 43FR, 43RL, and 43RR function as beams in the longitudinal direction of the diaper 1.
The crotch region 1B can be made difficult to shrink.

Further, the full-surface adhesive portions 43FL, 43FR, 43RL, and 43RR are arranged at the ends of the diaper 1 in the width direction. When the diaper 1 is viewed in the width direction, a linear adhesive portion 42F is arranged between the full-surface adhesive portion 43FL and the full-surface adhesive portion 43FR, and a linear adhesive portion 42F is arranged between the full-surface adhesive portion 43RL and the full-surface adhesive portion 43RR. A bonding portion 42R is arranged. In this way, by providing the full-surface adhesive portions at both ends of the diaper 1 in the width direction, it is possible to make the central portion in the width direction, which is between the full-surface adhesive portions, difficult to shrink.

The diaper 1 also includes a left lower leg opening 2L and a right lower leg opening 2R through which the wearer's lower legs are inserted, as shown in FIG. Leg opening edges 2KL and 2KR forming the leg openings 2L and 2R are formed including the cover sheet 4 and the inner cover sheet 5 . Further, as shown in FIG. 4, the full-surface adhesive portions 43FL and 43RL are formed along the leg opening edge 2KL up to the leg opening edge 2KL. Similarly, the full-surface adhesive portions 43FR and 43RR are formed along the leg opening edge 2KR up to the leg opening edge 2KR. As a result, the cover sheet 4 and the inner cover are partly formed at the leg opening edges 2KL and 2KR of the portions extending obliquely to the longitudinal direction of the diaper 1, that is, the leg opening edges 2KL and 2KR other than the crotch region 1B. A full-surface adhesive portion can be provided over the entire area without forming a non-bonded area with the sheet 5 . As a result, the feel of the widthwise end portions of the exterior sheet can be made uniform over the entire area.

The thread rubbers 4F3, 4R3 are adhered to the cover sheet 4 and the inner cover sheet 5 by full-surface adhesive portions 43FL, 43FR, 43RL, 43RR. The thread rubbers 4F3, 4R3 extend from the crotch region 1B side of the side seal portions SL, SR along the lower leg opening edges 2KL, 2KR. Leg gathers for contracting the leg openings 2L and 2R are formed by the rubber threads 4F3 and 4R3. In this embodiment, the rubber threads 4F3 and 4R3 for forming the leg gathers can be prevented from coming off by bonding the rubber threads 4F3 and 4R3 at the respective full-surface adhesive portions.

Further, the diaper 1 includes another stretchable member extending along a direction perpendicular to the linear bonded portions 5L, the second linear bonded portions 40F, and the like when viewed from above. As another elastic member, for example, the thread rubbers 10L1 and 10R1 for the three-dimensional gathers 3BL and 3BR shown in FIG. There may be. When the linear bonded portions 5L and the second linear bonded portions 40F and the like extending in the width direction of the diaper 1 are provided with an interval in the longitudinal direction, the outer sheet is stretched in the longitudinal direction by the other stretchable member. Wrinkles extending in the width direction can be formed by shrinkage and the outer sheet located in the non-bonded region between the linear bonded portion 5L and the second linear bonded portion 40F. Since the wrinkles line the entire area, the diaper 1 presents a uniform appearance. It should be noted that, in the case where the separate stretchable member is not provided, it is difficult to control the wrinkle direction of the outer sheet, and the absorber is twisted due to the wrinkle direction, and the wearing comfort of the diaper 1 is deteriorated. Sometimes you end up doing it. Since the diaper 1 according to the present embodiment is provided with the additional stretchable member described above, it is possible to suppress deterioration in wearing comfort.

Also, the lower leg opening edges 2KL and 2KR have curves with a plurality of inflection points. At the inflection points of the leg opening edges 2KL and 2KR, the cutting direction of the blade of the cutting device when forming the leg openings 2L and 2R changes, so it may be difficult to cut the cover sheet 4 and the inner cover sheet 5 of the diaper 1. have a nature. In this embodiment, the full-surface adhesive portions 43FL, 43FR, 43RL, 43RR are provided including the inflection points of the lower leg opening edges 2KL, 2KR. As a result, the sheet can be easily cut along the leg opening edges 2KL and 2KR even at the inflection point, and the forming regions of the leg openings 2L and 2R can be cut out with high accuracy.

<Embodiment 2>
Next, the diaper 1 according to Embodiment 2 will be described. FIG. 5 is an example of an exploded perspective view of the diaper 1 according to Embodiment 2. FIG. In addition, the same code|symbol is attached|subjected about the component same as the component of Embodiment 1 mentioned above, and the description is abbreviate|omitted.

In this embodiment, the absorbent body 8 has a plurality of mats. The absorbent body 8 has an absorbent core 8c composed of a plurality of mats and a core wrap sheet 7 wrapping the absorbent core 8c. In this embodiment, as shown in FIG. 5, the absorbent core 8c has an upper absorbent mat 8a and a lower absorbent mat 8b. The upper absorbent mat 8a has a substantially hourglass shape with constrictions, and the lower absorbent mat 8b has a rectangular shape. The width of the lower absorbent mat 8b is substantially the same as the width of the constricted portion of the upper absorbent mat 8a. Thus, the absorbent core 8c may be formed by laminating two layers of absorbent mats. Note that the rubber threads 4F3 and 4R3 may be arranged on both the left and right sides and cut at the central portion in the width direction.

<Embodiment 3>
Next, the diaper 1 according to Embodiment 3 will be described. FIG. 6 is an example of a plan view schematically showing an unfolded and extended state of the diaper according to Embodiment 3. FIG. In addition, the same code|symbol is attached|subjected about the component same as the component of Embodiment 1 mentioned above, and the description is abbreviate|omitted.

A rubber thread 4F3 (an example of the "stretchable member" of the present disclosure) is provided so as to traverse in the left-right direction in the crotch region 1B on the front body side. More specifically, the rubber thread 4F3 is provided along the lower leg opening 2L on the front body region 1F side, crosses the crotch region 1B side in the width direction, and extends along the lower leg opening 2R, It is provided on the exterior sheet in a stretched state.

In the area crossed by the rubber thread 4F3, the inner cover sheet 5 and the absorbent body 8 are non-bonded (referred to as non-bonded area 15). Actually, the inner cover sheet 5 and the back sheet 6 are non-bonded in the non-bonded area 15 . In the present embodiment, a non-bonded region 15 is provided in the entire overlapping region of the crotch region 1B where the rubber thread 4F3 and the absorbent body 8 overlap. In addition, in FIG. 6, the non-adhesion area|region 15 is painted out and illustrated. The non-bonded area 15 is provided over the entire width of the backsheet 6 .

In the present embodiment, as shown in FIG. 6, the non-adhesive region 15 is formed from a portion where the rubber thread 4F3 crosses the crotch region 1B (hereinafter, this portion may be referred to as a "crossing portion of the rubber thread 4F3"). also extend to the front body region 1F side and the back body region 1R side. Further, as shown in FIG. 6 , the rubber thread 4F3 has a component in the longitudinal direction of the diaper 1 outside the absorber 8 in the width direction of the diaper 1 . Here, the longitudinal component is a component that extends and contracts along the longitudinal direction of the diaper 1. Even if the rubber thread 4F3 extends diagonally with respect to the longitudinal direction, has a longitudinal component.

The non-adhesive region 15 is formed to include the front body region 1F side of the extension region of the rubber thread 4F3. It has an elastic component. Therefore, the outer sheet (the cover sheet 4 and the inner cover sheet 5) in the non-bonded area 15 is pulled toward the front body area 1F by the rubber thread 4F3, and the inner body including the absorbent body 8 is also pulled by the outer sheet. It is pulled up to the 1F side. The diaper 1 having this configuration can suppress separation of the absorbent body 8 from the skin surface of the wearer by pulling up the absorbent body 8 on the skin surface side of the non-bonded region 15 toward the front body region 1F. In addition, if the non-bonded region 15 is formed to include the front body region 1F side from the extension region of the rubber thread 4F3, it is pulled toward the front body region 1F side by the rubber thread 4F3, and the interior including the absorbent body 8 is pulled. The body can also be pulled up to the front body area 1F side.

The non-adhesive region 15 is located at the front adjacent portion of the crotch. More specifically, the non-bonded region 15 is provided at a position corresponding to the female wearer's urethral opening or at a position corresponding to the wearer's groin.

Here, the case where the wearer of the diaper 1 is a woman will be described. When a woman wears the diaper 1, it is designed so that the urethral opening is generally located in the crossing portion of the rubber thread 4F3, that is, in the non-adhesive region 15. As shown in FIG. Thus, the non-bonded region 15 includes a region corresponding to the female wearer's urethral meatus. As described above, by pulling up the inner body including the outer sheet on the non-bonded area 15 and the absorbent body 8 to the front body region 1F side by the rubber thread 4F3, the absorbent body 8 is brought closer to the female urethral meatus, and urination is performed from the urethral meatus. It becomes easier for the urine to be absorbed to enter the absorbent body 8. Thereby, the diaper 1 can suppress leakage of urine.

Next, the case where the wearer of the diaper 1 is a man will be described. When the diaper 1 is worn by a man, the crossing portion of the rubber thread 4F3, that is, the non-adhesive region 15 is designed to be closer to the crotch region 1B than the man's penis (male genitalia). In other words, the male penis is positioned closer to the front body region 1F than the non-adhesive region 15 is. Thus, the non-bonded area 15 is closer to the crotch area 1B than the area corresponding to the penis. In the diaper 1, the inner body including the outer sheet on the non-bonded area 15 and the absorbent body 8 is pulled up to the front body region 1F side by the rubber thread 4F3, so that the absorbent body 8 is pressed against the back side of the testicles and corresponds to the penis. A space to hold the penis can be formed in the area to be held. Since the male wearer urinates through the urethral opening of the penis, the diaper 1 holds the penis to control the direction of urination and suppress leakage of urine.

In addition, when a man wears the diaper 1, it is designed so that the testicles are generally located at the site where the elastic thread 4F3 crosses the crotch region 1B. Therefore, the portion where the rubber thread 4F3 crosses the crotch region 1B includes a region corresponding to the testicles of the male wearer. The absorber 8 also swells along with the swelling of the testicles, but the testicles can be held by lifting the absorber 8 with the rubber thread 4F3. In addition, even if the position of the testicles is shifted or the position of the testicles with respect to the diaper 1 varies depending on the wearer, the non-bonded area 15 is provided so that the relative position of the crossing portion of the rubber thread 4F3 with respect to the testicles can be adjusted. It can be moved, and the testicle can be held by lifting the absorbent body 8 at the part where the testicle is located by the rubber thread 4F3.

Moreover, the diaper 1 can suppress contraction of the absorber 8 at the transverse portion of the rubber thread 4F3 by providing the non-bonded region 15 . If the absorber were to contract and come into contact with the wearer's skin, it would give the wearer a sense of discomfort and reduce wearing comfort. The diaper 1 according to the present embodiment can suppress deterioration in wearability by suppressing contraction of the absorbent body 8 . Moreover, if the absorber shrinks after absorbing urine, the pulp may collapse. The diaper 1 according to this embodiment can suppress the loss of shape of the absorbent body 8 by suppressing the shrinkage of the absorbent body 8 .

Further, the diaper 1 includes thread rubbers 4R3 provided on the exterior sheet in a stretched state along the left and right leg openings 2L and 2R on the back side of the wearer. A region between the right and left rubber threads 4R3 facing each other in the crotch region 1B is an anus-corresponding region 45 corresponding to the wearer's anus. In FIG. 6, the anus-corresponding region 45 is shown surrounded by a dotted line. Since the rubber thread 4R3 on both sides of the central portion in the width direction of the diaper 1 is not connected, the rubber thread 4R3 does not have stretchability in the central portion in the width direction. In other words, the rubber thread 4R3 does not extend to the anus-corresponding region 45, and the contractile force of the rubber thread 4R3 pulls the anus-corresponding region 45 outward, so that the anus-corresponding region 45 can be further separated from the skin surface. . Thereby, the diaper 1 can form a stool accommodating space for accommodating stool in the area corresponding to the anus 45 . By forming a feces accommodation space, the diaper 1 can suppress deterioration of wearing feeling caused by feces sticking to the wearer's skin or entering the gluteal cleft of the buttocks.

Here, the positional relationship between the non-bonded area 15 and the linear bonded portion 5L will be described. FIG. 6 shows the non-adhesive region 15 between the inner cover sheet 5 (exterior sheet) and the back sheet 6 (interior body). Bonded portions 40F and the like and full-surface bonded portions 43FL, 43FR, 43RL, and 43RR are formed. Thread rubber 4F3
, 4R3 are entirely adhered to the exterior sheet by full-surface adhesive portions 43FL, 43FR, 43RL, and 43RR.

The non-bonded area 15 substantially overlaps with the inner side (crotch side) in the width direction of the full-surface bonded portions 43FL and 43FR shown in FIG. there is The rubber thread 4F3 contracts on the non-skin surface side of the non-bonded area 15, pulling the exterior sheet inward in the width direction. On the crotch side (rear side) of the non-adhesive region 15, the exterior sheet and the interior body including the back sheet 6 and the absorbent body 8 are bonded by the linear bonding portion 5L with a predetermined width from the center of the width direction of the back sheet 6. Therefore, the exterior sheet is bent downward (non-skin surface side) starting from the frontmost linear adhesive portion 5L. When the diaper 1 in this state is worn, the widthwise end portions of the crotch portion are in a state along the inner thighs of the wearer. In the diaper 1, the linear adhesive portions 5L are spaced apart from each other in the longitudinal direction in the crotch portion, so that the diaper 1 can soften the contact with the skin. To prevent a sheet from biting into the skin. Thereby, the diaper 1 can suppress the deterioration of the wearing feeling in the crotch region 1B. After forming the linear adhesive portion 5L, the outer sheet is cut along the lower leg opening edges 2KL and 2KR (see FIG. 4) to form the left and right lower leg openings 2L and 2R. By cutting the outer sheet, the outer sheet is fluffed and bulky at the ends in the width direction where the linear bonded portions 5L are formed. As a result, in the diaper 1, when the widthwise ends of the crotch portion are placed along the inner thighs, the outer sheet can be soft against the skin.

<Other embodiments>
Next, another embodiment will be described. In Embodiments 1 and 3, the linear bonding portion 5L, the second linear bonding portion 40F, and the like are formed in a linear shape that is continuous in the width direction, but are formed in a dotted line shape that is discontinuous in the width direction. may
