Detailed Description

Embodiment 1 >

Hereinafter, a diaper according to embodiment 1 of the present utility model will be described with reference to the drawings. The following configurations of the embodiments are examples, and the present utility model is not limited to these configurations.

Fig. 1 is an example of a perspective view of an adult pants-type disposable diaper (hereinafter, simply referred to as "diaper") according to embodiment 1. In a diaper, a direction in which a front body disposed to face an abdomen of a wearer and a rear body disposed to face a back are connected 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, in a state where the diaper is worn by the 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 the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is referred to as the width direction (also referred to as the left-right direction). Further, the thickness direction is to be viewed as a plane. The diaper 1 has a length along the longitudinal direction and a width along the width direction orthogonal to the longitudinal direction, and is put on the crotch of the wearer. The term "direction" used herein means a direction which coincides with the front, rear, left, and right of the wearer in the state where the wearer wears the diaper 1. For example, in the case of the right-left direction as referred to in the present application, this means a direction which coincides with the right-left direction of the wearer in a state where the wearer wears the diaper 1.

In this 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 opening portions through which the left and right lower limbs of the wearer can be inserted is illustrated. In the present embodiment, a pants-type disposable diaper for adults is illustrated, but the "absorbent article" described 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 a crotch region 1B which is a region corresponding to a crotch region covering the pudendum (crotch) of a wearer in a worn state, a front body region 1F which is a region corresponding to the front body at the waist of the wearer and is used to cover the abdomen side of the wearer, and a back body region 1R which is a region corresponding to the back body at the waist of the wearer and is used to cover 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 a "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 through the left lower limb opening 2L, the right lower limb of the wearer inserted through the right lower limb opening 2R, and the trunk of the wearer entering the trunk opening 2T, the diaper 1 is fixed to the wearer's body in a state in which 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 disposed around 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 while wearing the diaper 1. 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 becomes a flow-out path of liquid between the diaper 1 and the skin of the wearer, a three-dimensional gather 3BL is provided in a left leg opening 2L around the thigh of the left leg of the wearer, a three-dimensional gather (not shown) is provided in a right leg opening 2R around the thigh of the right leg of the wearer, and a waist gather 3R and an abdomen gather 12 are provided in a portion around the abdomen of the wearer. Leg gathers 3LF, 3LR (leg gathers 3LR are not shown in fig. 1) are provided at positions around the root portions of the legs of the wearer. Further, leg gathers 3LF are provided in the front body region 1F, and leg gathers 3LR are provided in the rear body region 1R. In fig. 1, only the leg gather 3LF is illustrated. The three-dimensional gathers 3BL, 3BR and the waist gathers 3R contract by the elastic force of the stretchable members and are 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 is absorbed by the absorber of the diaper 1 almost without leaking out from 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 having an absorber, and absorbs discharged liquid of a wearer. When the combined diaper 1 and inner pad is used, the inner pad is placed on the skin surface side of the diaper 1 so as to abut against 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 then absorbed. Therefore, 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 all of the inner pad, only the inner pad needs to be replaced even if the discharged liquid is generated, so that the intervention 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 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 (outer 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 that are attached together to form the outer surface of the diaper 1, and are substantially 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 wearing the 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, a linear rubber is used as the expansion member. Further, as the expansion and contraction member, a belt-shaped expansion and contraction member such as rubber may be appropriately selected instead of the linear rubber.

For example, in order to suppress leakage of discharged material, nonwoven fabrics composed of a liquid-impermeable thermoplastic resin may be used as the material of the cover sheet 4 and the inner cover sheet 5. 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 and 10R are combined with each other to form an inner body, and as a concept corresponding to the inner body, the cover sheet 4 and the inner cover sheet 5 each provided with a linear rubber may be collectively referred to as an outer body (an example of an "outer body" in the present disclosure).

The diaper 1 has a back sheet 6, an absorber 8, and a top sheet 9 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 through the crotch in the longitudinal direction and a predetermined width in the width direction orthogonal 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 formed of a liquid impermeable thermoplastic resin as a material to suppress leakage of discharged material. Further, the back sheet 6 is provided with minute holes. The holes can be ventilated while preventing liquid penetration. 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. Part or all of the top sheet 9 has liquid permeability. Therefore, in a state where 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 and absorbed therein. Examples of the liquid-permeable sheet include woven fabrics, nonwoven fabrics, and porous films. In addition, the topsheet 9 may have hydrophilic properties.

The absorbent body 8 has a core wrap sheet 7 (an example of the "water-permeable sheet" of the present disclosure) wrapped by an absorbent core 8c and a core wrap sheet 8c. The absorbent core 8c is of a substantially hourglass shape with narrowed portions. The absorbent core 8c has the following configuration: in the gaps between the short fibers of cellulose fibers such as pulp fibers, rayon fibers, and cotton fibers and/or the short fibers obtained by hydrophilizing synthetic fibers such as polyethylene, polypropylene, and polyethylene terephthalate, a particulate absorbent resin (high molecular absorbent material) such as SAP (superabsorbent polymer: super Absorbent Polymer), which is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining water, is held. 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. In the present embodiment, the absorbent core 8c is formed of 1 pad, but the absorbent core 8c may be formed of a plurality of pads.

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 be mixed into other structures. In addition, the deformation of the absorbent core 8c can be suppressed. The core wrap 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, but may be composed of 2 sheets, that is, an upper sheet disposed on the skin side of the wearer and a lower sheet disposed on the non-skin side of the wearer and wound around the side surface and the skin side of the absorbent core 8 c. In the case where the core wrap sheet 7 is formed of 2 sheets, the width-direction end portion of the upper side sheet may be formed of another sheet (for example, side sheets 10L and 10R, back sheet 6, and top sheet 9 described later). Further, since the absorber 8 is wrapped with the back sheet 6 and the top sheet 9, the shape of the absorber can be suppressed by these sheets, and therefore, the core wrap sheet 7 may not be provided.

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 longitudinal ends 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 whether the wearer discharges the liquid in the abdomen-down posture or the back-down posture, the discharged liquid is brought into contact with the absorber 8 via the top sheet 9.

Further, a linear rubber 4F7 (an example of the "1 st stretchable member" of the present disclosure) is provided between the back sheet 6 and the core wrap sheet 7 at the widthwise central portion in an elongated state in the longitudinal direction. The linear rubber 4F7 is bonded to the back sheet 6, and is bonded to the inner cover sheet 5 and the cover sheet 4 via the back sheet 6. The linear rubber 4F7 exerts a force that contracts the inner cover sheet 5 and the cover sheet 4 in the longitudinal direction. The region where the linear rubber 4F7 is provided is preferably a region where the absorber 8 and the inner cover sheet 5 are not bonded, but may be a region where the absorber 8 and the inner cover sheet 5 are bonded. The linear rubber 4F7 may be provided between the cover sheet 4 and the inner cover sheet 5.

Further, a linear rubber cover piece 13 (an example of the "telescopic member cover piece" of the present disclosure) is arranged on the skin surface side of the linear rubber 4F 7. The linear rubber cover sheet 13 is adhered to the back sheet 6 so as to cover 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 integrally bonded to the core wrap sheet 7 of the absorber 8. The linear rubber cover sheet 13 is disposed between the absorber 8 and the backsheet 6, is bonded to the backsheet 6, and is partially non-bonded to the core wrap sheet 7 of the absorber 8. This can prevent excessive elastic force (contraction force) of the linear rubber 4F7 from acting on the absorber 8, and can prevent excessive deformation of the absorber 8. In addition, when a band-shaped stretchable member is used instead of the linear rubber 4F7, the stretchable member and the core wrap 7 may be partially non-bonded so that the linear rubber cover 13 is not provided. 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. Further, a part of the linear rubber cover sheet 13 and the absorber 8 are non-bonded. The linear rubber cover sheet 13 may be integrally non-bonded to the absorber 8.

The diaper 1 has elongated belt-shaped side panels 10L and 10R 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 are bonded to the side sheets 10L and 10R in a state of being elongated in the longitudinal direction. Thus, 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, so that the diaper 1 in the finished state shown in fig. 1 is obtained, and thus the side sheets 10L, 10R are pulled in the longitudinal direction by the contraction force of the linear rubbers 10L1, 10R1 and rise from the top sheet 9 along the folding lines 10L2, 10R 2. As a result, three-dimensional gathers 3BL, 3BR are formed which prevent liquid from flowing out of 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 such an extent that the inner pad enters. The bonding method of the edge 4F4 and the edge 4R4, and the edge 4F5 and the edge 4R5 is not particularly limited, and can be performed by, for example, heat sealing, high-frequency sealing, ultrasonic sealing, or the like.

The diaper 1 further includes an end sheet 11F laminated on the wearer-side surface in the front region 1F of the cover sheet 4 and an end sheet 11R laminated on the wearer-side surface in the back region 1R of the cover sheet 4 with the backsheet 6, the absorber 8, the top sheet 9, and the side sheets 10L and 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 are bonded to the inner cover piece 5 by the adhesive. The end sheets 11F, 11R are disposed closer to the skin surface side 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. 3A and 3B are an example of a diagram schematically showing a state in which the diaper 1 of embodiment 1 is unfolded and elongated. Fig. 3A schematically shows an internal configuration in the case of the diaper 1 in an unfolded and elongated state as viewed from the left side. Fig. 3B schematically shows a plan view of the diaper 1 in an unfolded and extended state.

As shown in fig. 3B, a linear rubber 4F3 (an example of the "2 nd stretchable member" of the present disclosure) forming the leg gathers 3LF is provided along 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 bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state. The linear rubber 4F3 is disposed transversely across the crotch region 1B on the front side in the left-right 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 the wearer when the diaper 1 is worn. The arrangement of the linear rubber 4F3 in the region overlapping the absorber 8 in the thickness direction is not limited to the case of crossing as shown in fig. 3B. The linear rubber 4F3 may have a component in the width direction, and the linear rubber 4F3 may have a component in the width direction larger than a component in the length direction in the extending 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. The linear rubber 4R3 is bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state. 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 suitably bonded by an adhesive through the back sheet 6 from the front region 1F to the back region 1R. However, as shown in fig. 3B, in the region where the linear rubber 4F3 crosses in the precursor region 1F, the inner cover sheet 5 and the absorber 8 are non-bonded (as non-bonded regions 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. 3A and 3B, the linear rubber 4F7 is provided in the crotch region 1B at the widthwise central portion between the backsheet 6 and the core wrap 7 in a state of being elongated in the longitudinal direction. In practice, the linear rubber 4F7 is provided between the back sheet 6 and the linear rubber cover sheet 13 (not shown in fig. 3B). Further, the rear side of the linear rubber 4F7 corresponds to the anus of the wearer when the diaper 1 is worn by the wearer. The absorber 8 is extruded in a linear shape so as to surround the linear rubber 4F7, and is shown as a line 14 in fig. 3B. The line 14 is provided 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 on the front body region 1F side. Such pressing of the absorber 8 is achieved by embossing by a roller, for example.

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 adhering the linear rubber (linear rubber) 4F1 in an elongated state to the front body region 1F of the cover sheet 4 and adhering the linear rubber (linear rubber) 4R1 in an elongated state to the rear body region 1R of the cover sheet 4. The linear rubbers 4F1 and 4F2 are provided in the order of the linear rubbers 4F1 and 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 gather 12 is formed by adhering the linear rubber 4F2 in an elongated state to the front body region 1F of the cover sheet 4 and adhering the linear rubber 4R2 in an elongated state to the rear body region 1R of the cover sheet 4. The linear rubbers 4R1 and 4R2 are also provided in the order of the linear rubbers 4R1 and 4R2 from the side of the folded-back line 4RF along the folded-back line 4RF that forms the upper edge of the rear body region 1R when folded back, similarly to the linear rubbers 4F1 and 4F 2.

Therefore, 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 and 4F2 and the linear rubbers 4R1 and 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 portion on the crotch region 1B side thereof.

The linear rubbers 4F1 and 4R1 are provided so as to extend in the left-right direction along the portions of the front body region 1F and the rear body region 1R that are the upper edges shown in fig. 1. The linear rubbers 4F2 and 4R2 are disposed in parallel with a predetermined interval. 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 put on the wearer by being brought into close contact with the wearer, and to prevent discharged liquid from leaking from the abdomen and back. The linear rubbers 4F2 and 4R2 alleviate the sense of compression to the wearer due to 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 and extends to the arrangement region of the linear rubber 4F1 and the linear rubber 4R1, and the arrangement region of the linear rubber 4F1 and the linear rubber 4R1 is reinforced by the folded back portion. The end pieces 11L, 11R (see fig. 2) are provided in the arrangement regions of the linear rubbers 4F2, 4R2 where the cover piece 4 folded back at the folding lines 4FF, 4RF does not extend, and reinforce the arrangement regions of the linear rubbers 4F2, 4R 2.

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

The line 14 formed in the absorber 8 will be described with reference to fig. 4 to 6. Fig. 4 is a plan view showing the absorbent body 8, a part of the linear rubbers 4F3, 4R3, and the linear rubber 4F7 extracted from the diaper 1. Fig. 5 is a sectional view in the case where the diaper 1 is cut in the width direction at the line V-V of fig. 3B. Fig. 6 is a sectional view in the case where the diaper 1 is cut in the width direction at the VI-VI line of fig. 3B.

As shown in fig. 4, the wire 14 has 5 slots. The 5 grooves are constituted by grooves 14AL, 14AR (an example of "the 2 nd groove" of the present disclosure), grooves 14BL, 14BR (an example of "the 1 st groove" of the present disclosure), and groove 14C (a high-rigidity portion). The grooves 14AL, 14AR are a pair of left and right grooves formed in the absorber 8 and extending from the crotch region 1B toward the outer side in the width direction center of the diaper 1 toward the front body region 1F side end portions in the region corresponding to the groin of the wearer. The grooves 14AL, 14AR are pressing grooves formed by pressing the absorber 8. The grooves 14AL and 14AR may be formed by pressing only the absorbent core 8c, or may be formed by pressing the absorbent body 8 including the core wrap sheet 7. In the present embodiment, the grooves 14AL, 14AR are formed by pressing the core wrap sheet 7 and the absorbent core 8c from the skin surface side. The absorber 8 is folded along the groin of the wearer by forming the grooves 14AL, 14 AR.

The absorber 8 and the inner cover sheet 5 are formed as non-bonded areas 15, and the non-bonded areas 15 are provided so as to overlap with the grooves 14AL, 14AR when the areas provided with the grooves 14AL, 14AR are seen in plan view. In fig. 4, the non-adhesive region 15 is illustrated as being full of ground pattern. If the non-adhesive region 15 is formed so as not to include the region overlapping the grooves 14AL, 14AR, and the absorber 8 and the inner cover sheet 5 are adhered to each other in this region, the outer body is expanded to be in a state of abutting against the skin side, and as a result, the state of the outer body is transmitted to the absorber 8, and a force approaching from a state of bending along the groin portion to a flat state acts on the absorber. On the other hand, the diaper 1 according to the present embodiment is configured as described above, and the absorber 8 can be brought into contact with the skin surface side while maintaining the folded state of the absorber 8 folded along the groin portion. This improves the close contact between the absorbent body 8 and the skin of the wearer in the diaper 1.

As shown in fig. 4, the non-adhesive region 15 extends in the width direction of the diaper 1 and has a substantially rectangular shape. Although not shown in fig. 4, the non-adhesive region 15 extends to the widthwise end of the outer body of the diaper 1. In the wearing state of the diaper 1, the absorber 8 is pushed up to the skin surface side by the outer body in a state where the outer body is pulled in the left-right direction, and the absorber 8 can be made to abut against the skin surface of the wearer. This improves the close contact between the absorbent body 8 and the skin of the wearer in the diaper 1.

In the case of the diaper 1 as seen in plan view as shown in fig. 4, the diaper 1 has the linear rubber 4F3 bonded to the inner cover sheet 5 and the cover sheet 4 in an elongated state in the region overlapping the unbonded region 15. As shown in fig. 3B, the end portions of the linear rubber 4F3 are disposed at the width-directional end portions of the left and right lower limb openings 2L and 2R. By inserting the legs into the lower limb openings 2L, 2R provided in the outer body, the outer body is pulled in the widthwise outer direction, and the linear rubber 4F3 is also pulled in the widthwise outer direction. In this way, in the region extending in the width direction across the crotch region 1B of the linear rubber 4F3, the outer body is lifted up toward the skin surface side, and a non-adhesive region 15 where the absorbent body 8 and the outer body are non-adhesive is provided. Therefore, the absorber 8 is lifted up so as to approach the skin surface side by the outer body while maintaining the state of bending along the groin portion. In the present embodiment, the linear rubber 4F3 for forming leg gathers extends in the non-bonded region 15 and is connected to each other in the left-right direction, but the linear rubber provided in the non-bonded region 15 and crossing the crotch region 1B and the linear rubber for forming leg gathers may be provided. The end portion of the linear rubber 4F3 may be bonded to the outer body, and the linear rubber may be bonded to another sheet disposed between the outer body and the back sheet in the non-bonding region 15 which is the widthwise central portion. Even with such a configuration, the diaper 1 can obtain the above-described effects as long as the backsheet and the other sheet are non-bonded in the non-bonded region 15.

Next, the grooves 14BL, 14BR will be described. The grooves 14BL, 14BR are a pair of left and right grooves formed in the absorber 8 and extending in the longitudinal direction in the region corresponding to the urethral orifice of the wearer. The grooves 14BL, 14BR are pressing grooves formed by pressing the absorber 8. The grooves 14BL, 14BR may be formed by pressing only the absorbent core 8c, or may be formed by pressing the absorbent body 8 including the core wrap sheet 7. In the present embodiment, the grooves 14BL, 14BR are formed by pressing the core wrap sheet 7 and the absorbent core 8c from the skin surface side. The absorber 8 has grooves 14BL and 14BR, and thus the absorber 8 between the grooves bulges toward the urethral orifice. In this way, the diaper 1 can bring the absorber 8 into contact with the urethral opening, and therefore, the adhesion of the absorber 8 to the skin of the wearer can be improved.

The linear rubber 4F3 is disposed so as to include a region overlapping the precursor regions 1F of the grooves 14BL and 14BR when viewed in plan. With this configuration, the effect of the absorber 8 abutting against the skin surface side of the wearer by the linear rubber 4F3 in the folded state is improved. This is because: by providing the non-adhesive region 15 in the region where the linear rubber 4F3 and the absorber 8 overlap, the absorber 8 is not deformed by contraction of the linear rubber 4F3, and the absorber 8 having a shape bent by the grooves 14BL and 14BR can be made to abut against the skin side. In order to produce this effect, it is preferable that the linear rubber 4F3 is pulled in the left-right direction in a state in which the legs are inserted into the left and right lower limb openings 2L, 2R, thereby pressing the absorber 8 against the skin. Therefore, the linear rubber 4F3 is preferably a linear rubber for forming leg gathers, in which the end portions are disposed at the end portions in the width direction of the diaper 1. When the linear rubber 4F3 for forming leg gathers overlaps the grooves 14AL, 14AR as viewed in the thickness direction, the absorber 8 folded along the groin portion is preferably brought into contact with the skin surface side of the wearer by the contraction force of the linear rubber 4F 3. When the linear rubber 4F3 for forming leg gathers overlaps the grooves 14BL and 14BR as viewed in the thickness direction, the absorbent body 8 is preferably placed against the urethral orifice or an inner pad (pad) disposed on the top sheet 9 is preferably placed against the urethral orifice. As shown in fig. 4, the diaper 1 has 2 pieces of linear rubber 4F3 overlapped with the grooves 14AL and 14AR, and 1 piece of linear rubber 4F3 overlapped with the grooves 14BL and 14 BR. For example, the diaper 1 can be positioned on the abdomen side of the crotch center, at least on the abdomen side of the region corresponding to the urethral orifice, and the abdomen side ends of the grooves 14BL, 14BR can be lifted to the skin side by the linear rubber 4F3 at a minimum. The absorber 8 having a cross section in the width direction deformed to be convex by the grooves 14BL, 14BR is pressed against the skin, so that the convex shape is easily maintained in the entire areas of the grooves 14BL, 14 BR. The diaper 1 may have the following structure: the linear rubber 4F3 does not overlap the grooves 14AL, 14AR, and the linear rubber 4F3 overlaps the grooves 14BL, 14BR, so that if the linear rubber 4F3 for forming leg gathers overlaps the grooves 14BL, 14BR, it is suitable to bring the absorber 8 into abutment with the urethral meatus or bring the inner pad (diaper) disposed on the top sheet 9 into abutment with the urethral meatus. As in the present embodiment, the linear rubber 4F3 of the diaper 1 overlaps the grooves 14AL and 14AR and the grooves 14BL and 14BR, but it is needless to say that both of the above 2 suitable configurations may be employed. Further, if 3 pieces of linear rubber 4F3 are disposed on the back side of the area corresponding to the urethral orifice and the absorber 8 is disposed on the skin surface side, there is a possibility that the absorber will be convex and will sink into the gluteal cleft of the buttocks in the area corresponding to the anus, so that the 3 pieces of linear rubber 4F3 are suitably disposed in the position shown in fig. 4.

Further, the grooves 14AL, 14AR and the grooves 14BL, 14BR are not limited to the extrusion grooves. The grooves 14AL and 14AR and the grooves 14BL and 14BR may be formed by reducing the pulp distribution of the absorbent core 8c only in the groove forming portion, so long as the absorbent body 8 can be bent from the groove as a starting point. Further, by forming the grooves 14AL, 14AR and the grooves 14BL, 14BR as pressing grooves, the groove forming portion can be made highly rigid to prevent the groove forming portion from being deformed.

In the present embodiment, the groove 14AL is connected to the groove 14BL, and the groove 14AR is connected to the groove 14BR. Thereby, the grooves 14AL and 14BL, and the grooves 14AR and 14BR can be integrally formed. The grooves 14AL and 14BL may be adjacent to each other with a space therebetween, and the grooves 14AR and 14BR may be adjacent to each other with a space therebetween. In the case where the interval is provided between these grooves, the end of the groove 14BL may not be provided on the extension line of the groove 14AL, and the end of the groove 14BR may not be provided on the extension line of the groove 14 AR.

The non-adhesive region 15 includes a region overlapping the end of the grooves 14BL, 14BR on the precursor region 1F side in plan view. By inserting the legs into the lower limb openings 2L, 2R provided in the outer body, the outer body is pulled in the widthwise outer direction, and the linear rubber 4F3 is also pulled in the widthwise outer direction. In this way, in the region extending in the width direction across the crotch region 1B of the linear rubber 4F3, the outer body is lifted up toward the skin surface side, but a non-adhesive region 15 is provided in which the absorber 8 and the outer body are non-adhesive. Therefore, the absorber 8 is lifted up by the outer body so as to approach the urethral orifice side while being held in a state of being raised toward the urethral orifice side between the grooves 14BL, 14BR. In this way, the diaper 1 can bring the absorber 8 into contact with the urethral opening, and therefore, the adhesion of the absorber 8 to the skin of the wearer can be improved.

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 beyond the portion where the linear rubber 4F3 traverses the crotch region 1B (hereinafter, this portion may be referred to as a "traversing portion of the linear rubber 4F 3"). 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 refers to 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 formed so as to include the front region 1F side of the extension region of the linear rubber 4F3, and 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 cross section of the linear rubber 4F 3. 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 such a configuration, the absorber 8 is folded so as to protrude toward the skin side from the grooves 14BL and 14BR, and in this state, the absorber 8 on the skin side of the non-adhesive region 15 is lifted toward the front body region 1F side, whereby the absorber 8 can be prevented from leaving the skin surface of the wearer. Further, if the non-adhesive region 15 is formed closer to the front body region 1F than the extension region of the linear rubber 4F3, the non-adhesive region can be pulled toward the front body region 1F by the linear rubber 4F3, and the inner body including the absorber 8 can be lifted toward the front body region 1F.

Here, a case where the wearer of the diaper 1 is a female will be described. When the diaper 1 is worn by a female, the urethral orifice is designed so as to be located substantially 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 and the inner body including the absorber 8 in the non-adhesive region 15 toward the front body region 1F by the linear rubber 4F3, the absorber 8 bent so as to protrude toward the skin side from the grooves 14BL and 14BR approaches the urethral orifice of the female, and urine discharged from the urethral orifice is likely to enter the absorber 8. Thereby, the diaper 1 can suppress leakage of urine.

The end portions of the pair of parallel grooves 14BL, 14BR on the front side (front side) of the front region 1F overlap with the non-bonded region 15 when the diaper 1 is viewed in plan. Thus, the outer body does not hinder the absorbent body 8 from being folded so as to protrude toward the skin side from the grooves 14BL, 14BR, and the diaper 1 can fold the absorbent body 8 toward the skin side and contact the urethral orifice of the female wearer.

The non-adhesive region 15 extends to the front region 1F side (front side) of the region corresponding to the urethral orifice of the female wearer. This can more reliably prevent the outer body from being folded so that the blocking absorbent body 8 protrudes toward the skin from the grooves 14BL and 14 BR.

Next, the groove 14C will be described. The groove 14C is formed in the absorber 8, is disposed closer to the rear body region 1R than the grooves 14BL, 14BR, and extends in the width direction. The groove 14C is a pressing groove formed by pressing the absorber 8. The grooves 14C may be formed by pressing only the absorbent core 8C, or may be formed by pressing the absorbent body 8 including the core wrap sheet 7. In the present embodiment, the grooves 14C are formed by pressing the core wrap sheet 7 and the absorbent core 8C from the skin surface side.

The groove 14C is a pressing groove, and therefore is a high-rigidity portion as compared with the outside of the groove forming region. Further, since the grooves 14BL and 14BR are formed in the diaper 1, the absorber 8 is narrowed in the lateral direction by the legs of the wearer in the wearing state, and the absorber 8 is folded so as to protrude toward the skin side from the grooves 14BL and 14BR, thereby improving the adhesion to the urethral meatus. However, if the portion of the absorber 8 protruding toward the skin side from the grooves 14BL, 14BR extends to the anus of the wearer, the absorber 8 protrudes toward the anus, and the absorber 8 may enter the cleft (fissure) of the buttocks, causing discomfort to the wearer. When the absorber 8 enters the cleft of the buttocks, the feces discharged from the anus is pushed up to the skin surface side by the absorber 8, and the feces may be abutted against the skin. Therefore, the absorber 8 becomes convex toward the anus and the absorber 8 enters the natal cleft of the buttocks, which is undesirable.

In order to suppress the occurrence of this problem, the diaper 1 of the present embodiment is formed with the grooves 14C. The diaper 1 has the grooves 14C, so that the absorber 8 can be prevented from protruding toward the skin side in the area of the diaper 1 corresponding to the anus. The diaper 1 is provided with the groove 14C, which is a highly rigid portion extending in the left-right direction, in the area corresponding to the anus, thereby forming a space between the anus, the natal cleft, and the absorber 8, and suppressing the occurrence of the above-described problem. In fig. 4, the area corresponding to the anus (anus corresponding area) 30 is an area where the anus of the wearer is located in the wearing state of the diaper 1.

The grooves 14BL, 14BR can be bent in a W-shape when the absorber 8 is cut in the width direction, and can bring the skin surface side of the absorber 8 into abutment with the urethral orifice. If the grooves 14BL, 14BR are provided only in the region corresponding to the urethral orifice, and the absorber 8 is planar at the portion other than the groove region, the grooves do not function as bending means for the absorber 8. Therefore, the grooves need to be extended longer than the corresponding area of the urethral meatus. Therefore, in the present embodiment, the pair of right and left slits 14BL, 14BR extending in the longitudinal direction of the diaper 1 extend from the region corresponding to the urethral orifice on the abdomen side to the region corresponding to the anus 30 on the back side. The anus corresponding region 30 is a region where the anus of the wearer is located in the wearing state of the diaper 1. In the diaper 1 of the present embodiment, the grooves 14BL and 14BR are extended to the anus corresponding region 30, so that the absorber 8 can be bent in a W shape to improve the adhesion of the absorber 8 to the urethral opening of the wearer. However, if the grooves 14BL, 14BR are formed to the anus corresponding region 30 and the absorber 8 is bent along the grooves 14BL, 14BR, there is a possibility that the absorber 8 gets into the cleft (fissure) of the buttocks of the wearer. When the absorber is caught in the cleft of the wearer's buttocks, the wearer feels a sense of pressure, and the feces discharged from the wearer is abutted against the skin surface around the cleft of the buttocks, and the sense of wearing is reduced. Thus, the diaper 1 of the present embodiment has the groove 14C. In this way, the diaper 1 prevents the absorber 8 from being caught in the natal cleft of the wearer by suppressing the absorber 8 in the anus corresponding region 30 from being bent along the grooves 14BL, 14BR, and can suppress a decrease in the wearing feeling.

In the present embodiment, since the grooves 14BL and 14BR are also extrusion grooves, the grooves 14BL and 14BR and the groove 14C can be formed in the same step. In addition, the tank 14C may be connected to the tanks 14BL, 14 BR. Thereby, the grooves 14BL, 14BR and the groove 14C can be integrally formed. Further, even if the groove 14C is connected to the grooves 14BL, 14BR, the absorber 8 is convex toward the skin side between the grooves 14BL, 14BR, but the absorber 8 is suppressed from being convex in the back side thereof, that is, in the formation region of the groove 14C. The grooves 14BL and 14BR are arranged on the front region 1F side of a region corresponding to the anus of the wearer (anus corresponding region 30). This makes it possible to prevent the absorber 8 from protruding in the area corresponding to the anus (anus corresponding area 30) in the diaper 1.

The diaper 1 has a linear rubber 4F7 bonded in an elongated state in the longitudinal direction on the non-skin surface side of the absorber 8. The linear rubber 4F7 is disposed in a region overlapping with the pair of grooves 14BL, 14BR and stretches in the longitudinal direction. The linear rubber 4F7 contracts the inner cover sheet 5 and the cover sheet 4, which are the outer body, and pushes up the absorber 8 toward the skin surface side. In this way, the diaper 1 can lift the absorber 8 between the pair of grooves 14BL, 14BR toward the skin surface side at a portion protruding toward the urethral orifice side by the action of the outer body. Since the diaper 1 can bring the absorber 8 into contact with the urethral opening, the adhesion of the absorber 8 to the skin of the wearer can be improved.

The linear rubber 4F7 extends between the pair of left and right grooves 14AL and 14AR when the diaper 1 is viewed in plan. In the region where the absorber 8 is folded around the grooves 14AL, 14AR as the starting points and is in a state of being along the groin portion, the outer body is contracted in the longitudinal direction and is in a state of being floated on the non-skin side, and is easily deformed along the root portion of the leg. This can improve the wearing feeling of the diaper 1.

As described above, the linear rubber 4F7 extends between the grooves 14AL and 14AR and between the grooves 14BL and 14 BR. As shown in fig. 3A and 3B, the linear rubber 4F7 does not overlap with the linear rubber 4F2 for abdominal puckering in a state where the diaper 1 is viewed in plan. With this structure, the diaper 1 forms a space with the skin surface of the wearer on the crotch region 1B side of the abdominal gathers, and urine in the lateral direction reaching the front body region 1F side (abdominal side) is likely to pass to the other lateral direction. For example, in the case where the wearer is a male, when the wearer urinates with the distal end of the male genitals facing either the right or left direction, urine tends to pass around the other right or left direction, so that the diaper 1 can suppress leakage of urine.

The linear rubber 4F7 is disposed on the front body region 1F side of the region corresponding to the anus of the wearer (anus corresponding region 30). In other words, the linear rubber 4F7 is disposed on the precursor region 1F side of the groove 14C. With this configuration, the diaper 1 lifts the outer body toward the skin surface side by the contraction force of the linear rubber 4F7, thereby lifting the convex portion of the absorber 8 toward the skin surface side between the grooves 14BL, 14BR, and suppressing the lifting of the absorber 8 toward the skin surface side in the area corresponding to the anus (anus corresponding area 30). The diaper 1 can make the skin side of the diaper 1 easily leave the anus.

In the area corresponding to the anus of the wearer (anus-corresponding area 30), the linear rubber 4F7 and the absorber 8 are non-bonded. This configuration will be described with reference to fig. 5 and 6. As shown in fig. 6, the linear rubber cover piece 13 also extends in the area corresponding to the anus (the area where the groove 14C is formed). Therefore, since the non-skin surface side of the linear rubber cover sheet 13 and the core wrap sheet 7 is non-adhesive, a minute gap is formed between the linear rubber cover sheet 13 and the absorber 8 in the extending region of the linear rubber 4F7 as shown in fig. 5. The linear rubber 4F7 and the linear rubber 4R3 contract to pull the outer body, and the gap is widened. Thus, the diaper 1 is more likely to form a space between the absorbent body 8 and the anus of the wearer. In the anus-corresponding region 30, the cover sheet 4 and the inner cover sheet 5 are non-bonded. Thus, the diaper 1 is more likely to form a space between the absorbent body 8 and the anus of the wearer.

Next, a case where the wearer of the diaper 1 is a male will be described. When the diaper 1 is worn by a male, the crossing portion of the linear rubber 4F3 is designed to be positioned closer to the crotch region 1B than the penis (male genitals) of the male. In other words, the penis of the male is positioned 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 on the crotch side of the region corresponding to the penis. By lifting the outer body and the inner body including the absorber 8 in the non-adhesive region 15 toward the front body region 1F by the linear rubber 4F3, the absorber 8 is abutted against the rear side of the testis, and a space for holding the penis can be 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 urination direction by holding the penis, and can suppress urination.

When the diaper 1 is worn by a male, the testis is designed so as to be located substantially at a portion where the linear rubber 4F3 crosses the crotch region 1B. Therefore, the portion of the linear rubber 4F3 crossing the crotch region 1B includes a region corresponding to the testes of the male wearer. The absorber 8 also bulges along with the bulge of the testis, but the testis can be held by lifting the absorber 8 by the linear rubber 4F 3. Even if the position of the testis is shifted or the position of the testis relative to the diaper 1 is different depending on the wearer, the non-adhesive region 15 is provided, whereby the relative position of the crossing portion of the linear rubber 4F3 relative to the testis can be moved, 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, the diaper 1 is provided with the non-adhesive region 15, whereby shrinkage of the absorber 8 at the crossing portion of the linear rubber 4F3 can be suppressed. If the absorber contracts and contacts the skin of the wearer, the wearer is given a sense of discomfort and the wearing sensation is reduced. The diaper 1 of the present embodiment can suppress the reduction of the wearing sensation by suppressing the shrinkage of the absorber 8. In addition, there is a possibility that pulp may be scattered when the absorber contracts after absorption of urine. The diaper 1 of the present embodiment can suppress the shape of the absorber 8 by suppressing the shrinkage of the absorber 8.

As shown in fig. 3A and 3B, the diaper 1 has a linear rubber 4F2 (an example of a "3 rd stretchable member" of the present disclosure) disposed on the front region 1F side of a 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. Therefore, 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 absorber 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.

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. In order to prevent the front edge of the space holding the penis from being contracted by the linear rubber 4F7 and being broken, the linear rubber 4F7 does not extend to the arrangement region of the linear rubber 4F 2. The diaper 1 of the present embodiment can maintain a space for holding the penis satisfactorily.

< 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 shown in fig. 4. In this case, the absorber 8 can be prevented from being displaced with respect to the inner cover sheet 5. The partially bonded portion may be, for example, a widthwise central portion.

Embodiment 2 >

Next, a diaper 1 according to embodiment 2 will be described. Fig. 7A and 7B are an example of a diagram schematically showing a state in which the diaper 1 of embodiment 2 is unfolded and elongated. Fig. 7A schematically shows an internal configuration in the case of the diaper 1 in an unfolded and elongated state as viewed from the left side. Fig. 7B is a plan view of the diaper 1 in an unfolded and extended state. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof is omitted.

As shown in fig. 7A and 7B, the linear rubber 4F7 extends in the longitudinal direction from the front body region 1F side to the crotch region 1B. More specifically, the linear rubber 4F7 extends to the front side (the abdomen side of the wearer) of the grooves 14AL, 14 AR. The grooves 14AL and 14AR are grooves along the groin of the wearer, and when the wearer is a male, the penis is housed on the front side of the grooves 14AL and 14 AR. The diaper 1 forms a space for accommodating the penis of the wearer on the front side of the grooves 14AL, 14AR, and the linear rubber 4F7 is disposed on the non-skin surface side of the space, whereby the absorber 8 is lifted toward the skin surface side by the action of the linear rubber 4F7 in the space. Thus, the diaper 1 can prevent the absorber 8 from being excessively separated from the skin of the wearer in the space accommodating the penis, maintain the orientation of the penis in a predetermined direction (toward the widthwise center of the diaper 1), and prevent urine leakage during urination.

Embodiment 3 >

Next, a diaper 1 according to embodiment 3 will be described. Fig. 8 is an example of an exploded perspective view of the diaper according to embodiment 3. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof is omitted.

The absorbent body 8 has an absorbent core 8c composed of a plurality of pads and a core wrap sheet 7 wrapped around the absorbent core 8c. In the present embodiment, as shown in fig. 8, 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. In the present embodiment, the upper absorbent pad 8a is substantially hourglass-shaped with a narrowed portion near the central portion. Thus, two layers of absorbent pads may be laminated to form the absorbent core 8c.

In the above-described embodiment, the outer body on the front body region side and the outer body on the rear body region side are integrally formed, but the outer body on the front body region side and the outer body on the rear body region side may be separately provided.

The embodiments and modifications disclosed above can be combined separately.
