Description

Absorbent article

Technical Field

The present utility model relates to an absorbent article.

Background

Absorbent articles such as disposable diapers, diaper pads, and physiological products have been developed (for example, refer to japanese patent application laid-open publication No. 2019-115459). Japanese patent application laid-open No. 2019-115459 discloses a disposable diaper provided with a stretchable member around a portion of a wearer's leg. The disposable diaper is brought into close contact with the leg of the wearer by contraction of the stretchable member.

Disclosure of Invention

When the stretchable member disposed on the absorbent article is contracted, a force in a contraction direction acts on the absorber of the absorbent article, and the absorber is deformed in the contraction direction by the contraction force of the stretchable member. Deformation of the absorbent body in the absorbent article may deteriorate the close fitting property of the absorbent body with respect to the body of the wearer, or may deteriorate the absorption performance of the absorbent body, and is thus undesirable.

The present utility model aims to provide a technique capable of suppressing deformation of an absorber.

Detailed Description

< embodiment 1>

Hereinafter, a diaper according to an embodiment of the present utility model will be described with reference to the drawings. The following embodiments are examples, and the present utility model is not limited to these embodiments.

Fig. 1 is an example of a perspective view of a pants-type disposable diaper for adults (hereinafter, simply referred to as "diaper") according to embodiment 1. In a diaper, a direction connecting a front body disposed to face an abdomen of a wearer and a rear body disposed to face a back portion is referred to as a longitudinal direction (also referred to as a front-rear direction). The crotch portion disposed in the crotch (disposed opposite the crotch) of the wearer is located between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (the center in the longitudinal direction). In addition, when the diaper is worn on a wearer, the side facing the skin of the wearer is referred to as the skin surface side, and the opposite side to the skin surface side is referred to as the non-skin surface side. The direction connecting the skin surface side and the non-skin surface side is referred to as a thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is referred to as a width direction (also referred to as a left-right direction). In addition, the thickness direction is defined as a planar view. The diaper 1 has a length along the longitudinal direction and a width along the width direction orthogonal to the longitudinal direction, and is worn on the crotch of the wearer. The term "direction" used in the present application means a direction which coincides with the front, rear, left, and right of the wearer in a state where the diaper 1 is worn on the wearer. For example, in the present application, the term "right-left direction" means a direction which coincides with the right-left direction of the wearer when the diaper 1 is worn on the wearer.

In the present embodiment, as an example of the absorbent article, a pants-type disposable diaper having a tubular structure with a waist opening through which the abdomen of the wearer can be inserted and a pair of left and right leg openings through which the left and right lower limbs of the wearer can be inserted is exemplified. In the present embodiment, a pants-type disposable diaper for adults is exemplified, but the "absorbent article" as referred to in the present application is not limited to the pants-type disposable diaper for adults. The term "absorbent article" as used herein includes pants-type disposable diapers for children.

The diaper 1 has: the crotch region 1B is a portion corresponding to a crotch region that covers the pudendum (crotch) of the wearer in a worn state; the front body region 1F is a region corresponding to a front body in the waist of the wearer, and covers the abdomen side of the wearer; and a back region 1R, which is a portion corresponding to the back of the waist of the wearer, for covering the back side of the wearer. Here, the front body region 1F is located on the front side of the crotch region 1B, and the rear body region 1R is located on the rear side of the crotch region 1B. Since the diaper 1 in the present embodiment is a pants-type disposable diaper, the left edge of the front body region 1F and the left edge of the rear body region 1R are joined to each other, and the right edge of the front body region 1F and the right edge of the rear body region 1R are joined to each other. Thus, in the diaper 1, the trunk opening 2T (an example of the "waistline opening" in the present disclosure) is formed by the upper edge of the front body region 1F and the upper edge of the back body region 1R. In the diaper 1, a left leg opening 2L is formed in a left portion of the crotch region 1B where the above-described joining is not performed, and a right leg opening 2R is formed in a right portion of the crotch region 1B. When the diaper 1 is worn with the left lower limb of the wearer inserted into the left lower limb opening 2L, the right lower limb of the wearer inserted into the right lower limb opening 2R, and the trunk of the wearer entering the trunk opening 2T, the front body region 1F is disposed on the abdomen side of the wearer, the rear body region 1R is disposed on the back side of the wearer, and the left lower limb opening 2L and the right lower limb opening 2R are fixed to the wearer's body in a state surrounding the thigh of the wearer. Since the diaper 1 is fixed to the body of the wearer in this manner, the wearer can freely move in a state where the diaper 1 is worn. The left lower limb opening 2L and the right lower limb opening 2R are examples of the "two leg hole openings" of the present disclosure.

In the diaper 1, an absorber capable of absorbing and retaining liquid is mainly disposed around the crotch region 1B. In the diaper 1, in order to suppress formation of a gap which is a flow-out path of liquid between the diaper 1 and the skin of the wearer, a three-dimensional gather 3BL (an example of "leakage preventing wall" in the present disclosure) is provided in a left leg opening 2L surrounding the thigh of the left leg of the wearer, a three-dimensional gather 3BR (an example of "leakage preventing wall" in the present disclosure) is provided in a right leg opening 2R surrounding the thigh of the right leg of the wearer (not shown in fig. 1), and a waist gather 3R and a abdomen gather 12 are provided in a portion surrounding the abdomen of the wearer. Further, leg gathers 3LF, 3LR (leg gathers 3LR are not shown in fig. 1) are provided at positions surrounding the root portions of the legs of the wearer. Further, the leg gathers 3LF are provided in the front body region 1F, and the leg gathers 3LR are provided in the rear body region 1R. In fig. 1, only the leg gathers 3LF are illustrated. The three-dimensional gathers 3BL, 3BR and the waist gathers 3R are contracted by the elastic force of the stretchable member, and are thereby brought into close contact with the skin of the wearer. Further, the leg gathers 3LF, 3LR prevent the occurrence of gaps between the root portions of the legs of the wearer and the diaper 1. Thus, the discharged liquid discharged from the pudendum of the wearer hardly leaks out of the diaper 1 and is absorbed by the absorber of the diaper 1.

The diaper 1 can be used in combination with an inner pad, not shown. The inner pad is a substantially rectangular absorbent article provided with an absorber, and absorbs discharged liquid of a wearer. 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 abut on the discharge hole of the wearer. The discharged liquid is first absorbed by the inner pad, and only the discharged liquid which cannot be absorbed by the inner pad reaches the absorber of the diaper 1 and is further absorbed. Thus, even when the amount of discharged liquid is large, leakage of discharged liquid from the diaper 1 can be prevented. In addition, when the amount of discharged liquid is small and the discharged liquid can be absorbed by the inner pad, only the inner pad needs to be replaced even if the discharged liquid is discharged, so that the intervention (nursing) cost can be reduced. In addition, the frequency of changing the diaper 1 can be reduced, and the diaper 1 can be used for a long period of time.

Fig. 2 is an example of an exploded perspective view of the diaper 1 according to embodiment 1. The diaper 1 has a cover sheet 4 and an inner cover sheet 5. The cover sheet 4 and the inner cover sheet 5 are substantially hourglass-shaped (gourd-shaped) sheets bonded together to form the outer surface of the diaper 1, and have the same shape and substantially the same size except for the front region 1F-side end and the rear region 1R-side end. In a state of being worn on a wearer, the cover sheet 4 is laminated on the non-skin surface side of the wearer, and the inner cover sheet 5 is laminated on the skin surface side of the wearer. Between the cover sheet 4 and the inner cover sheet 5, stretchable members for forming the waist gathers 3R, the abdomen gathers 12, and the leg gathers 3LF, 3LR are provided. In the present embodiment, linear rubber is used as the expansion and contraction member. Further, as the expansion and contraction member, a belt-shaped expansion and contraction member such as rubber can be appropriately selected instead of the linear rubber.

For example, nonwoven fabrics made of a liquid impermeable thermoplastic resin may be used as the material of the cover sheet 4 and the inner cover sheet 5 in order to suppress leakage of discharged materials. Here, examples of the liquid-impermeable thermoplastic resin include Polyethylene (PE) and polypropylene (PP). Hereinafter, the absorber 8 and the back sheet 6, the top sheet 9, and the side sheets 10L, 10R are sometimes combined with each other to form an inner body, and the cover sheet 4 and the inner cover sheet 5 each provided with a linear rubber are sometimes referred to as an outer body (an example of an "outer body" in the present disclosure) as a concept corresponding to the inner body.

The diaper 1 has a back sheet 6 (an example of a "sheet-like member" in the present disclosure), an absorber 8, and a top sheet 9 (an example of a "water permeable sheet" in the present disclosure) laminated in this order on the wearer-side surfaces of the cover sheet 4 and the inner cover sheet 5. The back sheet 6 is a substantially rectangular sheet having a length extending from the front body to the rear body of the wearer through the crotch in the longitudinal direction and a predetermined width in the width direction perpendicular to the longitudinal direction. The absorber 8 and the top sheet 9 are sheet-like members having a substantially rectangular appearance like the back sheet 6, and are sequentially laminated on the back sheet 6 in a state where the longitudinal direction matches the longitudinal direction of the back sheet 6. The back sheet 6 is a sheet made of a liquid impermeable thermoplastic resin for suppressing leakage of discharged material. Further, the back sheet 6 is provided with minute holes. The holes can be ventilated while preventing liquid permeation. The holes are provided, for example, in the region overlapping the absorber 8. The top sheet 9 is a sheet-like member disposed on the skin surface side of the wearer so as to cover the water absorbing surface of the absorber 8. The top sheet 9 has liquid permeability in part or all of it. Thus, in a state in which the diaper 1 is worn, liquid discharged from the wearer is immersed in the absorbent body 8 through the topsheet 9 which may come into contact with the wearer's skin, where it is absorbed. Examples of the liquid-permeable sheet include woven fabrics, nonwoven fabrics, and porous films. In addition, the top sheet 9 may have hydrophilicity.

The absorber 8 has an absorbent core 8c constituted by a pad and a core wrap sheet 7 wrapping the absorbent core 8 c. The absorbent core 8c is of a substantially hourglass shape with narrowed portions. The absorbent core 8c has a structure in which a particulate absorbent resin (high molecular absorbent material) such as SAP (super absorbent polymer: super Absorbent Polymer) which is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining water is held in the interstices of a short fiber of cellulose fibers such as pulp fibers, rayon fibers or cotton fibers, or a short fiber obtained by hydrophilizing a synthetic fiber such as polyethylene, polypropylene or polyethylene terephthalate. When the absorbent core 8c absorbs liquid discharged from the wearer, the absorbent resin in the gaps held in the short fibers is swelled, and the liquid is held in the short fibers. In the present embodiment, the absorbent core 8c is substantially hourglass-shaped with a narrowed central portion. The absorbent core 8c can take 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 is less likely to be mixed into other structures. In addition, the absorbent core 8c is suppressed from running out. The core wrap sheet 7 can be formed of pulp fibers, and as an example, a tissue can be used. The core wrap sheet 7 may be 1 sheet, or may be composed of 2 sheets, that is, an upper sheet disposed on the skin surface side of the wearer and a lower sheet disposed on the non-skin surface side of the wearer and wound around the side surface of the absorbent core and the skin surface side. When the core wrap sheet 7 is formed of 2 sheets, the width direction end portion of the upper side sheet may be covered with another sheet (for example, side sheets 10L and 10R, back sheet 6, and top sheet 9 described later). The absorbent body 8 is enclosed by the back sheet 6 and the top sheet 9, and the sample can be prevented from being removed by these sheets, so that the core wrap sheet 7 may not be provided.

Further, between the back sheet 6 and the core wrap sheet 7, a linear rubber 4F7 (an example of the "3 rd stretchable member" of the present disclosure) is provided in the central portion in the width direction in an elongated state in the longitudinal direction from the front body region 1F to the crotch region 1B. A linear rubber cover piece 13 (telescopic member cover piece) is provided on the skin surface side of the linear rubber 4F 7. The linear rubber cover sheet 13 is adhered to the back sheet 6 while covering the linear rubber 4F7 from the skin surface side. The linear rubber cover sheet 13 is disposed between the linear rubber 4F7 and the absorber 8. The linear rubber cover sheet 13 is not bonded to the core wrap sheet 7 of the absorber 8. The linear rubber 4F7 is disposed between the absorber 8 and the back sheet 6, and is bonded to the back sheet 6 and is non-bonded to the absorber 8. This prevents the elastic force (contraction force) of the linear rubber 4F7 from acting on the absorber 8, and prevents the absorber 8 from being deformed. In addition, in the case of using a band-shaped stretchable member instead of the linear rubber 4F7, the stretchable member and the core wrap 7 can be made non-adhesive without providing the linear rubber cover sheet 13. In the present embodiment, the linear rubber cover sheet 13 is formed to have the same length as the back sheet 6. The linear rubber cover sheet 13 may be formed to have a length corresponding to the extension region of the linear rubber 4F7, or may be formed to be longer than the extension region of the linear rubber 4F7 and shorter than the back sheet 6. The linear rubber 4F7 may be provided between the cover sheet 4 and the inner cover sheet 5.

The back sheet 6, the absorber 8, and the top sheet 9 all extend from the front body region 1F to the back body region 1R. Thus, when the back sheet 6, the absorber 8, and the top sheet 9 are laminated to cover the wearer's pudendum (crotch), both ends in the longitudinal direction of each of the back sheet 6, the absorber 8, and the top sheet 9 are positioned on the wearer's abdomen side and back side. That is, the pudendum of the wearer is covered with the absorber 8 from the abdomen side to the back side of the wearer. Therefore, regardless of the posture of the wearer in which the wearer is facing the abdomen down and the posture of the wearer in which the wearer is facing the back down, the discharged liquid is discharged outside the body, and the discharged liquid is brought into contact with the absorber 8 via the top sheet 9.

The diaper 1 has elongated belt-shaped side panels 10L and 10R (an example of a "leakage preventing sheet" in the present disclosure) for forming the above-described three-dimensional gathers 3BL and 3BR. The side sheets 10L and 10R are provided on the long side of the top sheet 9. The linear rubbers 10L1 and 10R1 (an example of the "5 th stretchable member" in the present disclosure) are bonded to the side sheets 10L and 10R in a state of being elongated in the longitudinal direction. Thus, when the edge 4F4 of the cover sheet 4, which is the left edge of the front body region 1F, and the edge 4R4 of the rear body region 1R are joined to each other, and the edge 4F5 of the cover sheet 4, which is the right edge of the front body region 1F, and the edge 4R5 of the right edge of the rear body region 1R are joined to each other, the side sheets 10L, 10R are pulled up in the longitudinal direction by the contraction force of the linear rubbers 10L1, 10R1, and stand up from the top sheet 9 along the folding lines 10L2, 10R2, as shown in fig. 1, in the finished state of the diaper 1. As a result, three-dimensional gathers 3BL, 3BR are formed which prevent the outflow of liquid from the left and right lower limb openings 2L, 2R.

Here, regarding the side sheets 10L, 10R, when the three-dimensional gathers 3BL, 3BR are formed, the interval in the width direction between the standing lines of the three-dimensional gathers 3BL, 3BR is set to the extent that the inner pad enters. The bonding method of the edges 4F4 and 4R4, and the edges 4F5 and 4R5 is not particularly limited, but may be performed by, for example, heat sealing, high-frequency sealing, ultrasonic sealing, or the like.

The diaper 1 further includes an end sheet 11F that is laminated on the wearer side surface in the front region 1F of the cover sheet 4, and an end sheet 11R that is laminated on the wearer side surface in the back region 1R of the cover sheet 4, with the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R interposed therebetween. The end sheets 11F and 11R are long sheets that overlap the cover sheet 4 and the inner cover sheet 5 at one end side in the longitudinal direction of the top sheet 9. The end pieces 11F, 11R are non-water-impermeable nonwoven fabrics, and reinforce the cover piece 4 and the inner cover piece 5 mainly at the waist abutment portion of the diaper 1. The end pieces 11F and 11R are coated with an adhesive, and bonded to the inner cover piece 5 by the adhesive. The end sheets 11F, 11R are disposed closer to the skin surface than the laminate formed by the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R, and prevent the end portions of the laminate from directly contacting the skin surface to give the wearer a feeling of discomfort.

Fig. 3 is an example of a schematic view showing a state in which the diaper 1 according to embodiment 1 is unfolded and stretched. The left view of fig. 3 schematically shows the internal configuration of the diaper 1 in the developed and elongated state when viewed from the left side. The right-hand view of fig. 3 is a plan view of the diaper 1 in an unfolded and extended state.

As shown in fig. 3, the linear rubber 4F3 (an example of the "1 st stretchable member" of the present disclosure) forming the leg gathers 3LF is provided along the edges of the front body region 1F side of the right and left lower limb openings 2R and 2L into which the legs of the wearer enter when the diaper 1 is assembled. The linear rubber 4F3 is disposed in the crotch region 1B on the front side so as to cross in the lateral direction. At the portion where the linear rubber 4F3 is provided so as to traverse in the left-right direction in this way, the linear rubber 4F3 and the absorber 8 overlap in the thickness direction of the diaper 1. The widthwise central portion of such a transverse region is a region corresponding to the urethral orifice of a female wearer when the diaper 1 is worn. In the region overlapping the absorber 8 in the thickness direction, the arrangement of the linear rubber 4F3 is not limited to the crossing as shown in fig. 3. The linear rubber 4F3 may have a component in the width direction, and the linear rubber 4F3 may preferably have a component in the width direction larger than a component in the length direction.

On the other hand, the linear rubber 4R3 forming the leg gathers 3LR is provided along the edges of the rear body region 1R side of the right and left lower limb openings 2R and 2L. In the crotch region 1B on the rear body side, the tip end portion of the linear rubber 4R3 faces the width direction. However, the linear rubber 4R3 is cut at the center in the width direction, and the left linear rubber 4R3 and the right linear rubber 4R3 are not connected.

The inner cover sheet 5 and the absorber 8 are appropriately bonded by an adhesive through the back sheet 6 from the front region 1F to the back region 1R. However, as shown in fig. 3, in the region where the linear rubber 4F3 crosses, the inner cover sheet 5 and the absorber 8 are non-bonded (set as a non-bonded region 15). In fact, in the non-bonded region 15, the inner cover sheet 5 and the back sheet 6 are non-bonded. In the present embodiment, the non-adhesive region 15 is provided over the entire overlapping region of the crotch region 1B where the linear rubber 4F3 and the absorber 8 overlap.

As shown in fig. 3, the linear rubber 4F7 is provided in a state extending in the longitudinal direction from the front body region 1F to the crotch region 1B at the widthwise central portion between the back sheet 6 and the linear rubber cover sheet 13. The end portion side of the linear rubber 4F7 on the crotch region 1B side corresponds to the anus side of the wearer when the diaper 1 is worn by the wearer.

The cover sheet 4 is folded back at one end side at the folding lines 4FF and 4RF shown in fig. 2. The above-described waist gather 3R is formed by bonding the linear rubber 4F1 in an elongated state in the front region of the cover sheet 4 and bonding the linear rubber 4R1 in an elongated state in the rear region of the cover sheet 4. The linear rubbers 4F1, 4F2 (an example of the "2 nd stretchable member" of the present disclosure) are provided in order of the linear rubbers 4F1, 4F2 from the side of the folding line 4FF along the folding line 4FF that forms the upper edge of the precursor region 1F when folded back. Similarly, the abdominal gathers 12 are formed by bonding the linear rubber 4F2 in an elongated state in the front region 1F of the cover sheet 4 and bonding the linear rubber 4R2 in an elongated state in the rear region 1R of the cover sheet 4. The linear rubbers 4R1, 4R2 (an example of the "2 nd stretchable member" of the present disclosure) are also provided in the order of the linear rubbers 4R1, 4R2 from the side of the folding line 4RF along the folding line 4RF which forms the upper edge of the rear body region 1R when folded back, like the linear rubbers 4F1, 4F 2.

Thus, the linear rubbers 4F1, 4F2 are provided on the cover sheet 4 in such an orientation that the longitudinal direction, which is the expansion and contraction direction, is the lateral direction of the diaper 1. The linear rubbers 4R1, 4R2 are provided on the cover sheet 4 in such a manner that the longitudinal direction, which is the extension and contraction direction, is the lateral direction of the diaper 1. Thus, 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 linear rubbers 4F1, 4F2 and the linear rubbers 4R1, 4R2 form a substantially annular stretchable member surrounding along the trunk opening 2T, and function to shrink the trunk opening 2T in the trunk-surrounding direction. That is, the linear rubbers 4F1 and 4F2 and the linear rubbers 4R1 and 4R2 exert a contraction force to bring the diaper 1 into close contact with the wearer, thereby preventing a gap from being formed between the diaper 1 and the abdominal circumference of the wearer. The linear rubber 4F2 and the linear rubber 4R2 overlap the absorber 8 at a part of the crotch region 1B side thereof (details will be described later).

The linear rubbers 4F1 and 4R1 are provided so as to extend in the left-right direction along portions that are upper edges of the front body region 1F and the rear body region 1R shown in fig. 1. The linear rubbers 4F2 and 4R2 are disposed in parallel with a predetermined interval therebetween. The linear rubbers 4F1 and 4R1 fasten the abdomen of the wearer relatively strongly above the linear rubbers 4F2 and 4R2 in a state where the diaper 1 is worn. The linear rubbers 4F1 and 4R1 serve to prevent the diaper 1 from being brought into close contact with the wearer, thereby preventing the wearing position from being shifted, and preventing discharged liquid from leaking from the abdomen and back. The linear rubbers 4F2 and 4R2 alleviate the sense of compression to the wearer caused by the contraction force of the linear rubbers 4F1 and 4R 1.

The cover sheet 4 is folded back at the folding lines 4FF and 4RF to extend to the arrangement regions of the linear rubbers 4F1 and 4R1, and the arrangement regions of the linear rubbers 4F1 and 4R1 are reinforced by the folded back portions. The end pieces 11F and 11R (see fig. 2) are provided in the arrangement regions of the linear rubbers 4F2 and 4R2 where the cover piece 4 folded back at the folding lines 4FF and 4RF does not extend, and reinforce the arrangement regions of the linear rubbers 4F2 and 4R 2.

In the present application, the state in which the sheets overlap is not limited to a state in which the sheets overlapped with each other are overlapped with each other in a state of being entirely in contact with each other, and is a concept including a state in which a part of the sheets are overlapped with each other. For example, a portion of the end piece 11F on one end side in the longitudinal direction of the back piece 6 overlaps with a portion of the cover piece 4 in a contact state. In the diaper 1, the cover sheet 4, the end sheets 11F, 11R, the inner cover sheet 5, and the side sheets 10L, 10R are stacked in addition to the back sheet 6 and the top sheet 9 sandwiching the absorber 8, and therefore, it can be said that a laminate in which these multiple sheets are stacked is provided.

According to the diaper 1 described above, as shown in fig. 3, the inner cover sheet 5 and the absorber 8 are non-bonded in the non-bonded region 15 traversed by the linear rubber 4F3 in the crotch region 1B on the front body side. Thereby, the absorber 8 is pressed against the skin so as not to be contracted in the width direction by contraction of the linear rubber 4F3 provided between the cover sheet 4 and the inner cover sheet 5. In addition, such non-adhesive region 15 corresponds to the urethral orifice of a female wearer. This makes it easy for the diaper 1 to contact the absorber 8 in a flat state without wrinkles or the like against the urethral orifice of the wearer while suppressing deformation of the absorber 8. This can immediately absorb urine excreted from the wearer, and can prevent urine excreted from the wearer from leaking out of the diaper 1. In addition, when the inner pad is used in combination, the inner pad is pressed against the urethral orifice by the absorber 8 which does not generate wrinkles or the like, so that leakage of urine to the outside of the diaper 1 can be similarly prevented.

Further, since wrinkles and the like are suppressed from occurring in the absorber 8, when the wearer is a male, the male sexual organ is held by the absorber 8, so that the male sexual organ can be pressed against the skin side, and the urination direction can be kept constant. This can suppress leakage of urine to the outside of the diaper 1.

In addition, according to the diaper 1 described above, as shown in fig. 3, the linear rubber 4R3 is cut at the widthwise central portion. As a result, the elastic force of the linear rubber 4R3 does not act on the cover sheet 4 and the inner cover sheet 5 in the region where the linear rubber 4R3 is cut, and the cover sheet 4 and the inner cover sheet 5 in the region do not shrink. Further, since the diaper 1 suppresses deformation of the absorber 8, deterioration of the absorption performance due to deformation of the absorber 8 does not occur.

In addition, according to the diaper 1 described above, the linear rubber 4F3 extending in the width direction contracts, and a contraction force acts on the cover sheet 4 and the inner cover sheet 5 in the width direction. The cover sheet 4, the inner cover sheet 5, and the absorber 8, which are subjected to the contraction force in the width direction, are non-bonded. As a result, the regions 55L and 55R (see fig. 3) of the cover sheet 4 and the inner cover sheet 5 that are located on the outer side in the width direction than the absorber 8 are contracted so as to overlap the absorber 8 in the thickness direction. In the diaper 1, the linear rubbers 4F3 and 4R3 have a contraction force that causes the regions 55L and 55R on the outer side in the width direction than the overlapping region of the crotch region 1B overlapping the absorber 8 to contract on the inner side in the width direction than the overlapping region in the state where the waist opening is extended. Thus, when the waist opening is extended and the diaper 1 is worn, the wearer can prevent the wearer's thumb from getting caught in the regions 55L and 55R when putting the legs into the left and right lower limb openings 2L and 2R in order to wear the diaper 1. Thereby, the possibility of the wearer getting out of balance by hooking his/her feet to the diaper 1 and falling down is reduced.

The linear rubber 4R3 is cut at the widthwise central portion and does not extend in the widthwise direction. In the crotch region 1B on the back side, the cover sheet 4, the inner cover sheet 5, and the absorber 8 are bonded via the backsheet 6. As a result, in the back region 1R, the regions 56L, 56R (see fig. 3) of the cover sheet 4 and the inner cover sheet 5 existing on the outer side in the width direction than the absorber 8 can be restrained from shrinking so as to overlap with the absorber 8 in the thickness direction. This brings about the following states: on the front body side, the regions 55L and 55R overlap the absorber 8 in the thickness direction, and on the rear body side, the regions 56L and 56R extend toward the left lower limb opening 2L and the right lower limb opening 2R, respectively. This facilitates the front-rear distinction of the diaper 1, and thus improves the convenience of the wearer.

Further, according to the diaper 1 described above, as shown in fig. 2, minute holes are provided in the backsheet 6. The portion where the hole is provided is a region overlapping with the absorber 8. The back sheet 6 is provided with an inner cover sheet 5 on the non-skin surface side, and the inner cover sheet 5 and the absorber 8 are non-bonded in the non-bonded region 15. Thus, the air inside the diaper 1 communicates with the outside through the minute holes of the backsheet 6 and the non-adhesive region 15 between the absorber 8 and the inner cover sheet 5. This improves the ventilation in the diaper 1. In addition, according to the diaper 1 of the present embodiment, the cover sheet 4 and the inner cover sheet 5 contract with respect to the absorber 8 by contraction of the linear rubber 4F 3. Thereby, the space between the absorber 8 and the inner cover sheet 5 is enlarged in the non-bonded region 15. This improves the ventilation in the diaper 1. The linear rubber 4F3 is provided so as to include a region corresponding to the urethral orifice of the female wearer. This expansion of the space is thereby achieved in the region corresponding to the urethral orifice. This ensures ventilation in the region corresponding to the urethral orifice that is easily wetted. Thus, problems with the skin around the urethral orifice are suppressed.

The portion where the linear rubber 4F7 is provided includes a non-bonded region 15 where the absorber 8 and the inner cover sheet 5 are not bonded. As a result, the absorber 8 is pressed in the direction of the urethral orifice, and the non-adhesive region 15 between the absorber 8 and the inner cover sheet 5 spreads in the thickness direction. By expanding the non-adhesive region 15, the air permeability of the non-adhesive region 15 can be further improved.

Further, the contraction force of the linear rubber 4F7 in the longitudinal direction is transmitted to the inner cover sheet 5 via the back sheet 6. The holes provided in the back sheet 6 bonded to the inner cover sheet 5 are enlarged in the longitudinal direction. This improves the ventilation of the diaper 1. The holes of the back sheet 6 are provided in the region overlapping the absorber 8 in the thickness direction, and are therefore provided in the center in the width direction in bilateral symmetry. This makes it possible to spread the holes uniformly in the width direction and in the length direction. This can uniformly improve the air permeability. The same effect is also achieved when the linear rubber 4F7 is provided in the absorber 8.

< embodiment 2>

Next, a diaper 1 according to embodiment 2 will be described. Fig. 4 is an example of a plan view schematically showing a state in which the diaper according to embodiment 2 is developed and extended. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof will be omitted.

In the present embodiment, as shown in fig. 4, the non-adhesive region 15 extends toward the front body region 1F and toward the rear body region 1R at a position that is wider than the linear rubber 4F3 across the crotch region 1B in the width direction (hereinafter, this position may be referred to as a "crossing portion of the linear rubber 4F 3"). In fig. 4, the non-adhesive region 15 is shown by painting. As shown in fig. 4, the linear rubber 4F3 has a component in the longitudinal direction of the diaper 1 on the outer side of the absorber 8 in the width direction of the diaper 1. Here, the longitudinal component is a component that extends and stretches along the longitudinal direction of the diaper 1, and even if the linear rubber 4F3 extends obliquely to the longitudinal direction, the linear rubber 4F3 has a longitudinal component. The non-adhesive region 15 is provided over the entire width of the diaper 1.

The non-adhesive region 15 is formed so as to include the front region 1F side of the extension region of the linear rubber 4F3, and the linear rubber 4F3 has a component that stretches and contracts in the longitudinal direction of the diaper 1 on the outer side in the width direction of the portion crossing the absorber 8. Therefore, the outer body (the cover sheet 4 and the inner cover sheet 5) in the non-adhesive region 15 is pulled toward the front body region 1F by the linear rubber 4F3, and the inner body including the absorber 8 is also lifted toward the front body region 1F by the outer body. In the diaper 1 having this structure, the absorber 8 on the skin surface side of the non-adhesive region 15 is lifted toward the front body region 1F, so that the absorber 8 can be prevented from being separated from the skin surface of the wearer. Further, if the non-adhesive region 15 is formed so as to be located closer to the front body region 1F than the extension region of the linear rubber 4F3, the linear rubber 4F3 pulls the front body region 1F, and the inner body including the absorber 8 can be lifted up toward the front body region 1F.

Here, a case where the wearer of the diaper 1 is a female will be described. The design is as follows: when the diaper 1 is worn by a female, the urethral orifice is located approximately at the crossing portion of the linear rubber 4F 3. Thus, the crossing portion of the linear rubber 4F3 includes an area corresponding to the urethral orifice of the female wearer. As described above, by lifting the outer body on the non-adhesive region 15 and the inner body including the absorber 8 toward the front body region 1F by the linear rubber 4F3, the absorber 8 is brought closer to the urethral orifice of the female, and urine discharged from the urethral orifice easily enters the absorber 8. Thereby, the diaper 1 can suppress leakage of urine.

Next, a case where the wearer of the diaper 1 is a male will be described. The design is as follows: when the diaper 1 is worn by a male, the crossing portion of the linear rubber 4F3 is located closer to the crotch region 1B than the penis (male sexual organ) of the male. In other words, the penis of the male is located on the front region 1F side of the crossing portion of the linear rubber 4F 3. Thus, the crossing portion of the linear rubber 4F3 is located closer to the crotch region 1B than the region corresponding to the penis. In the diaper 1, the outer body in the non-adhesive region 15 and the inner body including the absorber 8 are lifted toward the front body region 1F by the linear rubber 4F3, so that the absorber 8 is pressed against the rear side of the testis, and a space for holding the penis is formed in the region corresponding to the penis. Since the male wearer urinates from the urethral orifice of the penis, the diaper 1 can control the direction of urination and suppress leakage of urine by holding the penis.

In addition, it is designed to: when the diaper 1 is worn by a male, the testes are positioned approximately where the linear rubber 4F3 crosses the crotch region 1B. Thus, the portion of the linear rubber 4F3 crossing the crotch region 1B includes a region corresponding to the testes of the male wearer. Along the swelling of the testis, the absorber 8 also swells, but the testis can be held by lifting the absorber 8 with the linear rubber 4F 3. In addition, even if the position of the testis is deviated or the position of the testis with respect to the diaper 1 is different depending on the wearer, by providing the non-adhesive region 15, the crossing portion of the linear rubber 4F3 can be moved relative to the testis, and the absorber 8 at the portion where the testis is located can be lifted by the linear rubber 4F3, thereby holding the testis.

Further, by providing the non-adhesive region 15 in the diaper 1, shrinkage of the absorber 8 at the crossing portion of the linear rubber 4F3 can be suppressed. If the absorber contracts to contact the skin of the wearer, the wearer is surprised and the wearing sensation is reduced. The diaper 1 of the present embodiment can suppress the decrease in the wearing sensation by suppressing the shrinkage of the absorber 8. In addition, if the absorber shrinks after absorption of urine, pulp may be lost. The diaper 1 of the present embodiment can suppress the deformation of the absorber 8 by suppressing the shrinkage of the absorber 8.

The diaper 1 further includes a linear rubber 4F2 (an example of the "2 nd stretchable member" of the present disclosure) disposed on the front region 1F side of the region corresponding to the penis of the wearer. As described above, the linear rubber 4F2 stretches in the width direction of the diaper 1, and overlaps the absorber 8 at a part of the crotch region 1B side thereof. Thus, the linear rubber 4F2 pulls the absorber 8 in the width direction in the wearing state of the diaper 1. Specifically, the linear rubber 4F2 pulls the end portion of the absorber 8 on the front body region 1F side in the width direction in the wearing state of the diaper 1. Thereby, the front edge of the space for holding the penis of the male is formed on the front region 1F side of the absorber 8. In the present embodiment, the absorbent body 8 is pulled in the width direction by the linear rubber 4F2 forming the abdominal gathers 12 (see fig. 1), but a linear rubber may be provided separately. The linear rubber may be directly bonded to the absorber 8 or may be bonded to the outer body.

In addition, a plurality of (e.g., 3) linear rubbers 4F7 are provided in an elongated state along the longitudinal direction of the diaper 1. Here, the end portion of the linear rubber 4F7 on the front body region 1F side is located closer to the crotch region 1B than the arrangement region of the linear rubber 4F 2. The linear rubber 4F7 is not extended to the arrangement region of the linear rubber 4F2 so that the front edge of the space holding the penis is not contracted or broken by the linear rubber 4F 7. The diaper 1 of the present embodiment can maintain a space for holding the penis satisfactorily.

As described above, the absorber 8 has a substantially hourglass shape narrowed in the crotch region 1B. More specifically, the absorbent core 8c has a shape that narrows in the crotch region 1B and is wider in the width direction than the narrowing portion of the crotch region 1B on the side of the front body region 1F than the crossing portion of the linear rubber 4F 3. Since the outer body in the non-adhesive region 15 is lifted up toward the front body region 1F by the linear rubber 4F3 and the linear rubber 4F3 is contracted toward the inside in the width direction of the diaper 1, the outer body ( regions 55L, 55R shown in fig. 3) on the outside in the width direction of the absorbent body 8 in the non-adhesive region 15 is in a range overlapping the absorbent body 8, or at least the amount of extension of the outer body toward the outside in the width direction of the absorbent body 8 is smaller than that in the case where the linear rubber 4F3 is not provided. For example, if the width of the absorber 8 in the non-adhesive region 15 lifted up toward the front body region 1F by the linear rubber 4F3 is wider than the position before being lifted up, the outer cover is more likely to be more reliably positioned within the width of the absorber 8. Thus, the left and right leg openings 2L, 2R are less likely to be blocked by the outer body when the diaper 1 is worn. Accordingly, when the wearer wears the diaper 1 by self-force, the left and right lower limb openings 2L and 2R are easily observed from the trunk opening 2T, and when the wearer wears the diaper 1 by a caregiver (care giver) or the like, the left and right lower limb openings 2L and 2R are easily found from the outside, so that the diaper 1 is easy to wear. In addition, when the wearer puts the legs into the left and right lower limb openings 2L, 2R, the thumb is less likely to be hooked on the outer body.

The diaper 1 further includes a pair of linear rubbers 4R3 (the "4 th stretchable member" in the present disclosure) provided in the outer body in an elongated state along the left and right lower limb openings 2L, 2R on the back side of the wearer. The linear rubber 4R3 is adhered to the outer body. In addition, in the case where the linear rubber 4R3 is non-bonded to the outer body in the crotch region 1B, the shrinkage degree may be smaller than that of the linear rubber 4F 3. By configuring the linear rubber 4R3 in this way, the outer package of the arrangement region of the linear rubber 4F3 can be further contracted, and the degree of contraction of the outer package of the arrangement region of the linear rubber 4R3 can be reduced, thereby facilitating the front-rear distinction of the diaper 1.

In the crotch region 1B, an intermediate region facing the pair of right and left linear rubbers 4R3 serves as an anus corresponding region 45 corresponding to the anus of the wearer. In fig. 4, the anus corresponding region 45 is shown surrounded by a broken line. The linear rubber 4R3 does not connect the linear rubbers 4R3 on both sides at the widthwise central portion of the diaper 1, and therefore does not have a stretching force at the widthwise central portion. In other words, the linear rubber 4R3 does not extend to the anus-corresponding region 45, and the anus-corresponding region 45 is pulled outward by the contraction force of the linear rubber 4R3, so that the anus-corresponding region 45 can be further separated from the skin surface. Thus, the diaper 1 can form a feces storage space for storing feces in the anus-corresponding region 45. By forming the feces storage space, the diaper 1 can suppress a decrease in wearing sensation caused by the feces adhering to the skin of the wearer or the feces entering the cleft of the buttocks.

Fig. 5 is a cross-sectional view of the diaper according to embodiment 2, taken in the widthwise direction at the center in the longitudinal direction. The absorbent core 8c is surrounded by a water permeable core wrap sheet 7. The core wrap sheet 7 is divided into an upper core wrap sheet 7f positioned on the skin side of the wearer when worn and a lower core wrap sheet 7b positioned on the non-skin side of the wearer when worn. The upper core wrap sheet 7f and the lower core wrap sheet 7b are bonded to each other at the skin-face side end portion of the absorbent core 8 c. The upper core wrap sheet 7f is bonded to the skin surface side of the absorbent core 8 c. The lower core wrap sheet 7b is bonded to the non-skin side of the absorbent core 8 c.

The backsheet 6 is a water impermeable film laminated on the non-skin surface side of the absorbent body 8, and prevents the discharged liquid that has permeated the absorbent body 8 from leaking out to the cover sheet 4 side. The back sheet 6 is wider than the absorbent core 8c, and the side surface of the absorbent core 8c is wrapped in the skin surface side. The diaper 1 further includes a plurality of adhesive portions HM3 for adhering the lower core wrap sheet 7b and the backsheet 6 on the non-skin surface side of the absorber 8. The plurality of bonding portions HM3 are formed separately from each other.

The top sheet 9 is a water permeable sheet that abuts the skin surface of the wearer. When discharged from the wearer, the discharged liquid permeates into the absorbent core 8c through the top sheet 9 and is absorbed. The top sheet 9 is also wider than the absorbent core 8c, and the side surface of the absorbent core 8c is wrapped so as to reach the non-skin surface side. On the skin surface side of the absorber 8, the top sheet 9 is laminated on the skin surface side of the back sheet 6.

The side sheets 10L and 10R are water impermeable nonwoven fabric sheets disposed on both sides in the width direction of the absorber 8, and constitute a pair of side sheets covering the side surfaces in the width direction of the absorber 8. The side sheets 10L and 10R further stand up toward the skin surface side at the skin surface side end portion of the absorbent body 8, and form three-dimensional gathers 3BL and 3BR for preventing lateral leakage of discharged liquid. The side sheets 10L, 10R are laminated on the skin surface side of the top sheet 9 on the skin surface side of the absorber 8.

In the side surface portion of the absorber 8 of the diaper 1 in the present embodiment, a top sheet 9 and side sheets 10L and 10R made of nonwoven fabric are laminated on the further outer side of the back sheet 6 as a water impermeable sheet. By covering the side surface of the absorber 8 with a plurality of nonwoven fabric sheets in this way, the backsheet 6, which is a water impermeable film at the side surface portion of the absorber 8, can be prevented from directly contacting the skin surface of the wearer and giving the wearer a feeling of strangeness. The side surface of the absorber 8 is reinforced by being covered with a plurality of sheets, and the absorbent core 8c is prevented from being deformed.

The back sheet 6 has a folded portion 6A that is folded back toward the skin surface side at the widthwise end portion of the absorber 8 and extends toward the skin surface side of the absorber 8. The back sheet 6 is folded back toward the skin surface side of the absorber 8 so that the folded back portion 6A covers the widthwise end portion of the absorber 8. Between the folded-back portion 6A and the top sheet 9, an adhesive portion HM1 is applied by a hot melt adhesive so as to extend in the longitudinal direction of the diaper 1. By applying the hot melt adhesive, the folded back portion 6A and the top sheet 9 are bonded.

The side sheets 10L and 10R for forming the three-dimensional gathers 3BR and 3BL are disposed outside the center in the width direction of the diaper 1 and on the skin surface side of the top sheet 9. Further, an adhesive portion HM2 (an example of the "adhesive portion" of the present disclosure) is applied between the top sheet 9 and the side sheets 10L, 10R by a hot melt adhesive so as to extend in the longitudinal direction of the diaper 1. By applying the hot melt adhesive, the top sheet 9 and the side sheets 10L, 10R are bonded. The adhesive parts HM1 and HM2 are integrally formed when viewed in the thickness direction. This is because: the hot-melt adhesive is applied from the skin surface side of the top sheet 9, and the adhesive parts HM1, HM2 are formed by the hot-melt adhesive cured between the top sheet 9 and the folded-back parts 6A of the back sheet 6 by penetrating the top sheet 9 and the hot-melt adhesive cured between the top sheet 9 and the side sheets 10L, 10R. In the diaper 1, the discharged liquid does not penetrate the top sheet 9 and reaches the non-skin surface side, and leakage of the liquid from the non-skin surface side can be suppressed.

The side sheets 10L and 10R cover the widthwise ends of the top sheet 9 and the back sheet 6. Thus, even when the liquid permeates to the width-direction end side of the adhesive portions HM1, HM2, the diaper 1 can suppress lateral leakage.

The side panels 10L, 10R are folded outward on the inner side in the width direction of the diaper 1 than the adhesive portion HM2, and have free ends 3BL1, 3BR1 at the distal ends. The free ends 3BL1, 3BR1 become the top ends on the rising side when the three-dimensional gathers 3BL, 3BR are rising. The side sheets 10L and 10R have linear rubbers 10L1 and 10R1 which extend in the longitudinal direction of the diaper 1 and are bonded in an elongated state. By contracting the linear rubbers 10L1, 10R1, three-dimensional gathers 3BL, 3BR are formed which rise up to the wearer side from the inside of the adhesive portion HM2 to the free ends 3BL1, 3BR1. Here, at least one of the 3 linear rubbers 10L1 is different in color from the linear rubber 4F 3. For example, 1 of the 3 linear rubbers 10L1 on the free ends 3BL1, 3BR1 side may be different in color from the linear rubber 4F 3.

The diaper 1 can be visually confirmed by contracting the outer body at the crossing portion of the linear rubber 4F3 by contracting the linear rubber 4F3, and opening the left and right lower limb openings 2L, 2R widely on the front region 1F side, whereby the three-dimensional gathers 3BL, 3BR can be visually confirmed by visually confirming the left and right lower limb openings 2L, 2R from the front region 1F side, and the linear rubbers 10L1, 10R1 can also be visually confirmed. Since the linear rubber 10L1 is marked with a different color from the linear rubber 4F3, the diaper 1 can be identified that the linear rubber 10L1 of a different color is visually recognized from the left and right lower limb openings 2L, 2R to be the front side, and the front and rear identification can be made easy. For example, the linear rubbers 10L1, 10R1 of the free ends 3BL1, 3BR1 may be labeled with a different color from the side sheets 10L, 10R. This can improve the visibility of the linear rubbers 10L1 and 10R1.

< embodiment 3>

Next, a diaper 1 according to embodiment 3 will be described. Fig. 6 is an example of a plan view schematically showing a state in which the diaper according to embodiment 3 is developed and extended. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof will be omitted.

As shown in fig. 6, the absorber 8 is linearly extruded so as to surround the linear rubber 4F7, and is shown as a line 14 (an example of a "high rigidity portion" in the present disclosure) in fig. 6. The line 14 is disposed at the end portion on the crotch region 1B side in the width direction. The wire 14 is bent outward in the width direction at the end portion on the precursor region 1F side. Such pressing of the absorber 8 is achieved by embossing with a roller, for example. The absorbent body 8 has a line 14 extending in the longitudinal direction of the diaper 1 in the non-bonded region 15. Since the absorber 8 is lifted up by the linear rubber 4F3 and is easily creased in the width direction of the absorber 8 to protrude toward the skin side, a line 14 extending in the longitudinal direction is formed to prevent the absorber 8 from deforming into a convex shape. In addition, in addition to the wires 14, the high rigidity portion may also be provided by increasing the pay-per-view of the pulp, stacking the materials much more, or applying a hot melt adhesive.

According to the diaper 1 of the present embodiment, as shown in fig. 6, the linear rubber 4F7 is provided between the back sheet 6 and the linear rubber cover sheet 13 in a state of extending in the longitudinal direction from the front body region 1F to the crotch region 1B. Thereby, the cover sheet 4 and the inner cover sheet 5 shrink in the longitudinal direction. Further, since the thread 14 as a pressing region is provided in the absorber 8, the bending of the thread 14 induces the absorber 8 to bulge toward the skin surface side. This allows the absorber 8 to reliably contact the urethral orifice. This can prevent urine excreted from the wearer from leaking out of the diaper 1. The same effect is also achieved when the linear rubber 4F7 is provided in the absorber 8.

In addition, according to the diaper 1 of the present embodiment, the centerline 14 extends in the width direction in the region corresponding to the anus in the crotch region 1B. Since the wire 14 has higher rigidity than other regions, the absorber 8 can be restrained from being deformed in the width direction. This prevents the absorber 8 from sinking into the buttocks of the wearer, and suppresses the decline of the wearing feeling.

< embodiment 4>

Next, a diaper 1 according to embodiment 4 will be described. Fig. 7 is an example of an exploded perspective view of the diaper 1 according to embodiment 4. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof will be omitted.

In the present embodiment, the absorber 8 has a plurality of pads. The absorber 8 has an absorbent core 8c composed of a plurality of pads and a core wrap sheet 7 wrapping the absorbent core 8c. In the present embodiment, as shown in fig. 7, the absorbent core 8c has an upper absorbent pad 8a and a lower absorbent pad 8b. The upper layer absorbent pad 8a is substantially hourglass-shaped with narrowed portions, and the lower layer absorbent pad 8b is rectangular. The width of the lower absorbent pad 8b is substantially the same as the width of the narrowed portion of the upper absorbent pad 8 a. Thus, the absorbent pad can be laminated with 2 layers to form the absorbent core 8c.

< modification >

In the above-described embodiment, the absorber 8 and the inner cover sheet 5 are non-bonded in the non-bonded region 15 where the linear rubber 4F3 crosses in the width direction, but the absorber 8 and the inner cover sheet 5 may be partially bonded in the non-bonded region 15. In this case, the absorber 8 can be prevented from being displaced relative to the inner cover sheet 5. The partial bonding portion may be, for example, a widthwise central portion.

In embodiment 1 described above, the regions 55L and 55R of the cover sheet 4 and the inner cover sheet 5 are contracted in the width direction by contraction of the linear rubber 4F3, and the regions 56L and 56R are respectively extended to the left lower limb opening 2L and the right lower limb opening 2R, but all of the regions 55L and 55R and the regions 56L and 56R may be contracted in the width direction so as to overlap the absorber 8 by contraction force of the linear rubber 4F 3.

The arrangement of the linear rubber 4F7 is not limited to the above embodiment, and may be provided so that the minute holes of the back sheet 6 and the non-adhesive region 15 between the absorber 8 and the inner cover sheet 5 can be enlarged. For example, the linear rubber 4F7 may be disposed at the end in the width direction symmetrically with respect to a center line disposed at the center in the width direction and extending in the length direction. In addition, in the case where the linear rubber 4F7 is provided on the end portion side in the width direction in addition to the above-described embodiment, the skin surface side and the non-skin surface side of the minute hole can be opened more widely. This can improve the ventilation.

In the above-described embodiments, the effect of preventing leakage of urine excreted from the wearer has been described, but leakage of water, feces, or sweat contained in watery feces excreted from the wearer can be similarly prevented.

The linear rubber 4R3 may be formed continuously in the crotch region 1B so as to traverse the absorber 8, similarly to the linear rubber 4F 3. In this case, a non-adhesive region similar to the non-adhesive region 15 is also provided at the crossing portion of the linear rubber 4R3, and the outer body in the non-adhesive region is pulled toward the rear region 1R by the linear rubber 4R3, so that the inner body including the absorber 8 can be lifted toward the rear region 1R by the outer body. For example, when the wearer is not prone to get up, and urine flows into the back region 1R to form a urine pool, the linear rubber 4R3 lifts the absorber 8, so that the gap between the absorber 8 and the skin due to the formation of the urine pool can be suppressed.

The embodiments and modifications disclosed above can be combined separately.
