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 publication 2019-115459 discloses a pants-type diaper having a stretchable member provided at a portion surrounding a leg portion of a wearer.

Disclosure of Invention

The absorbent article is often formed entirely of the same color. For example, most of underpants type diapers are formed of white as a whole. In addition, in the pants-type diaper, the front and rear shapes and structures are almost the same, and it is sometimes difficult to distinguish between the front and rear.

The present utility model provides a technique for facilitating the distinction between front and rear of an absorbent article.

The absorbent article according to an aspect of the present utility model has a length along a longitudinal direction and a width along a width direction orthogonal to the longitudinal direction. The absorbent article is provided with: an absorber provided at a position including a crotch portion and configured to absorb discharged liquid of a wearer; a waist opening configured to allow insertion of the abdomen circumference of the wearer; two leg-surrounding openings configured to allow the legs of the wearer to be inserted therethrough; an outer body disposed on a non-skin surface side of the wearer than the absorber; a 1 st stretchable member having a color different from that of the outer body, the stretchable member being provided on the outer body along the leg hole opening portion on the abdomen side of the wearer; and a 2 nd stretchable member having the same color as the outer body and provided on the outer body along the leg hole opening portion on the back side of the wearer.

In the absorbent article according to one aspect of the present utility model, the 1 st stretchable member may be provided in the outer body in an elongated state so as to extend along the leg hole opening on one side, to extend across the crotch portion, and to extend along the leg hole opening on the other side.

In one aspect of the present utility model, the absorbent article may further include a 3 rd stretchable member disposed on the non-skin surface side of the absorbent body and extending in the longitudinal direction. The 3 rd stretchable member may be provided at a central portion in the width direction, and may have a different color from the outer body and the absorber, and may be visually checked from the outside of the outer body. The 1 st stretchable member may extend in the crotch portion in such a manner as to pass through a region corresponding to the urethral meatus.

In one aspect of the present utility model, the absorbent article may further include a 4 th stretchable member provided in the outer body in an elongated state along the waist opening and stretchable in the width direction. The 4 th telescoping member may have a different color than the outer body on the ventral side of the wearer.

In the absorbent article according to an aspect of the present utility model, a non-adhesive region where the absorbent body and the outer body are non-adhesive may be provided in an overlapping region of the crotch portion where the 1 st stretchable member and the absorbent body overlap.

In one aspect of the present utility model, the absorbent article may further include a pair of left and right grooves provided in the absorbent body and extending in the longitudinal direction. The groove may be configured to overlap with the 1 st expansion member when viewed in the thickness direction.

An absorbent article according to an aspect of the present utility model may include: a water-permeable sheet which is disposed on the skin surface side of the absorber and has water permeability; and a pair of leakage preventing sheets adhered to the left and right end sides of the water permeable sheet in the width direction. The leakage preventing sheet may have a free end disposed on a distal end side of an end portion of the adhesive portion with the water permeable sheet, and a 5 th stretchable member disposed on the free end side and extending in the longitudinal direction and being adhered in an elongated state, and may be configured to form a leakage preventing wall rising from the end portion of the adhesive portion with the water permeable sheet to the wearer side by contraction of the 5 th stretchable member. The 5 th telescoping member may have the same color as the 1 st telescoping member.

According to the absorbent article of the first aspect of the present utility model, the front-rear distinction of the absorbent article becomes easy.

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 disposable diaper for adult use (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 disposed 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 a wearer. The term "direction" used in the present utility model 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 utility model, 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" 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 portion that covers the pudendum (crotch) of the wearer in a worn state; a front body region 1F, which is a region corresponding to a front body at the waist of the wearer, for covering 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 8 capable of absorbing and retaining liquid is arranged mainly 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 is provided in a left leg opening 2L surrounding the thigh of the left leg of the wearer, a three-dimensional gather (not shown) is provided in a right leg opening 2R surrounding the thigh of the right leg of the wearer, 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 (in fig. 1, leg gathers 3LR are not shown) 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 and 3BR (an example of "leakage preventing wall" of the present disclosure) and the waist gathers 3R are contracted by the elastic force of the stretchable member, and thereby 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 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 that has not been 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 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 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 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 absorber 8, and a top sheet 9 (an example of "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 are both liquid-permeable and breathable. 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 absorption 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 skin of the wearer, and is absorbed therein. 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 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. 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 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, 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. 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.

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), the respective longitudinal ends 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. Further, the linear rubbers 10L1, 10R1 (an example of the "5 th stretchable member" of the present disclosure) are bonded to the side sheets 10L, 10R in an elongated state along 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 which is the left edge 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 which is the right edge of the rear body region 1R are joined to each other, the side sheets 10L and 10R are pulled up in the longitudinal direction by the contraction force of the linear rubbers 10L1 and 10R1, and stand up from the top sheet 9 along the folding lines 10L2 and 10R2, as shown in fig. 1, the diaper 1 is completed. 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, but 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 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 laminated on the skin surface side of the laminate formed by the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R, and the end portions of the laminate are prevented from being in direct contact with 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 developed and extended. Part (a) of fig. 3 schematically shows an internal configuration in the case where the diaper 1 in the developed and elongated state is viewed from the left side. Part (B) 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 bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state. 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 the 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 component in the width direction in the extending direction of the linear rubber 4F3 may be preferably larger than the component in the length direction.

On the other hand, the linear rubber 4R3 (an example of the "2 nd expansion member" of the present disclosure) 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 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 in the precursor region 1F, 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.

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 a linear rubber (linear rubber) 4F1 in an elongated state in the front region of the cover sheet 4 and bonding a linear rubber (linear rubber) 4R1 in an elongated state in the rear region 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 gathers 12 (see fig. 1) 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 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, as with the linear rubbers 4F1 and 4F 2. The linear rubbers 4F1, 4F2, 4R1, and 4R2 are examples of the 4 th expansion and contraction member in the present disclosure.

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 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 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 after being folded back at the folding lines 4FF and 4RF is not extended, and the arrangement regions of the linear rubbers 4F2 and 4R2 are reinforced.

In the present application, the state in which the sheets overlap is not limited to the manner in which the sheets that overlap each other in a state in which the sheets are in full contact with each other, and is a concept including the manner in which a part of the sheets overlap 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.

As shown in fig. 3, the linear rubber 4F3 is provided on the outer body along the left and right lower limb openings 2L, 2R on the abdomen side (the front body region 1F side) of the wearer. The linear rubber 4R3 is provided on the outer body along the left and right lower limb openings 2L, 2R on the back side (the rear body region 1R side) of the wearer. The linear rubber 4F3 and the linear rubber 4R3 are expansion members for forming leg gathers.

The linear rubber 4F3 has a different color from the cover sheet 4 and the inner cover sheet 5 as the outer body. In the present embodiment, the entirety of the cover sheet 4 and the inner cover sheet 5 is white, and the entirety of the linear rubber 4F3 is colored (for example, blue, red, or the like) other than white. The whole of the linear rubber 4R3 is the same color as the outer body. Generally, diapers are mostly formed entirely of the same color. For example, most of underpants type diapers are formed of white as a whole. In addition, in the pants-type diaper, the front and rear shapes and structures are almost the same, and it is sometimes difficult to distinguish between the front and rear. On the other hand, in the diaper 1 according to the present embodiment, the linear rubber 4F3 provided on the abdomen side has a color different from that of the exterior body, and the linear rubber 4R3 provided on the back side has the same color as that of the exterior body. This makes it possible to easily distinguish the diaper 1 from each other in the front-rear direction. The linear rubber 4F3 may have only a part of a color different from that of the outer body. For example, the linear rubber 4F3 may have a color different from that of the outer body only in the portion extending in the width direction in the crotch region 1B.

Fig. 4 is a plan view showing the diaper 1 with the absorber 8 and a part of the linear rubbers 4F3 and 4R3 drawn out. In fig. 4, the non-adhesive region 15 is shown with a ground pattern. In the non-bonded region 15 where the linear rubber 4F3 crosses in the crotch region 1B on the front body side (abdomen side) as shown in fig. 4, the inner cover sheet 5 and the absorber 8 are non-bonded. Thus, the absorber 8 is abutted against the skin so as not to contract in the width direction by the contraction force of the linear rubber 4F3 provided between the cover sheet 4 and the inner cover sheet 5.

Here, the non-adhesive region 15 includes a region corresponding to the urethral orifice. The urethral opening corresponding region is a region where the urethral opening of the wearer is located in the wearing state of the diaper 1, and the center portion in the width direction of the non-adhesive region 15 corresponds to this. By providing the non-adhesive region 15, the absorber 8 is more likely to expand toward the non-skin surface side than the front and rear regions of the non-adhesive region 15 in the region corresponding to the urethral orifice. If the expansion of the absorber is completely restricted in the region corresponding to the urethral orifice, the absorption rate of urine by the absorber decreases. The decrease in absorption rate of the absorber may cause leakage of urine. Therefore, in the diaper 1 according to the present embodiment, the non-adhesive region 15 is provided in the region corresponding to the urethral orifice so that the absorber 8 can expand, and the contraction force of the linear rubber 4F3 lifts the absorber 8 on the skin surface side of the non-adhesive region 15 toward the skin surface side to bring the absorber 8 into contact with the urethral orifice, thereby making it easy for the absorber 8 to suck urine. In addition, when the wearer is a male, the absorber 8 is pushed up to the skin surface side to cover the male sexual organ, so that the absorber 8 easily sucks urine discharged from the tip of the male sexual organ. Since the absorber 8 of the diaper 1 according to the present embodiment easily sucks urine, leakage of urine to the outside can be suppressed.

In the diaper, the urethral orifice corresponding region is a region that absorbs and retains water content of urine, and tends to sag downward due to the weight of urine. In the present embodiment, the linear rubber 4F3 lifts the region corresponding to the urethral orifice from the non-skin surface side to the ventral surface side, and prevents the skin of the wearer from being separated from the diaper more than necessary (excessively). Further, the diaper 1 is configured such that excessive expansion of the absorber 8 in the region corresponding to the urethral orifice is restricted by the linear rubber 4F3, that is, the absorption rate of urine in the region corresponding to the urethral orifice is made small, and the urine is moved outside the region corresponding to the urethral orifice, so that the urine in the entire region of the absorber 8 can be absorbed and held. In addition, in the diaper 1, when the absorber 8 sags due to the weight of excrement, the absorber 8 in the region corresponding to the urethral orifice is allowed to expand and sag to prevent excessive compression to the urethral orifice, and the contraction force of the linear rubber 4F3 is used to prevent the region corresponding to the urethral orifice from being away from the urethral orifice, thereby preventing leakage. The diaper 1 according to the present embodiment can suppress leakage of urine.

In the present embodiment, the linear rubber 4R3 for forming leg gathers is used as a stretchable member for pulling the absorber 8 to the outside in the width direction. By passing the legs of the wearer through the left and right lower limb openings 2L, 2R, the linear rubber 4R3 is pulled outward in the width direction, whereby the linear rubber 4R3 can pull the absorber 8 further outward in the width direction.

In the present embodiment, the linear rubber 4R3 for forming leg gathers is used as a stretchable member for pulling the absorber 8 outward in the width direction, but the present invention is not limited thereto. For example, a stretchable member in which the absorber 8 is pulled outward in the width direction may be directly adhered to the absorber 8, or a stretchable member other than the linear rubber for forming leg gathers may be provided to the outer body. Here, when a stretchable member such as the linear rubber 4R3 is provided in the outer case to pull the absorber 8 to the outside in the width direction, the inner cover sheet 5 and the back sheet 6 are brought into a bonded state in the extending region of the stretchable member, and the back sheet 6 and the absorber 8 are brought into a bonded state. Thereby, the absorber 8 can be pulled by the elastic force of the telescopic member.

The inner end portion of the linear rubber 4R3 in the width direction overlaps the absorber 8 when viewed in the thickness direction, and has a component in the width direction in the expansion and contraction direction. Thus, the linear rubber 4R3 can more reliably pull the absorber 8 outward in the width direction.

Further, the inner cover sheet 5 is bonded to the absorber 8 between the pair of linear rubbers 4R 3. Here, between the pair of linear rubbers 4R3 is an anus corresponding region 30 shown in fig. 4. By bonding the absorber 8 to the outer case, the bending rigidity between the pair of linear rubbers 4R3 increases, and the cross-sectional shape is less likely to be W-shaped. In contrast, since the non-adhesive region 15 is provided in the region corresponding to the urethral orifice on the abdomen side, the absorber 8 is more likely to bend than the anus region 30. In order to facilitate bending of the absorber 8 in the region corresponding to the urethral orifice than the region corresponding to the anus 30, the bonded portion between the absorber 8 and the inner cover sheet 5 may be narrowed or the bonded portion may be narrowed gradually toward the abdomen side as compared with the region corresponding to the anus 30.

Further, the diaper 1 is made to be close to the waist by the linear rubbers 4F1 and 4F2 on the abdomen side and to be close to the leg circumference by the linear rubber 4F3, and thus, the vicinity of the anus of the wearer on the back side can be lifted from the wearer to form a space in the vicinity of the anus, and feces can be stored in the space. This can also suppress the deterioration of the wearing sensation of the diaper 1. Further, by providing the non-adhesive region 15, the contraction force of the linear rubber 4F3 does not act to contract the absorber 8 in the left-right direction to deform the absorber 8 into a W shape, but acts to raise the absorber 8 toward the skin surface side to improve the adhesion between the absorber and the skin in the region corresponding to the urethral orifice.

The abdomen-side linear rubbers 4F1 and 4F2 that are provided in the outer body in an elongated state along the trunk opening 2T and extend and contract in the width direction have a color different from that of the outer body (for example, a color such as red or blue). The diaper 1 according to the present embodiment can make the contour of the waist on the abdomen side clear by the linear rubbers 4F1 and 4F2 and the contour of the leg band on the abdomen side clear by the linear rubber 4F3, thereby greatly changing the impression on the abdomen side and the back side. Thereby, the diaper 1 can be more easily distinguished from each other in the front-rear direction.

In the present embodiment, a non-adhesive region 15 is provided in a region where the linear rubber 4F3 and the absorber 8 overlap. If the non-adhesive region 15 is not provided and the absorber 8 and the inner cover sheet 5 are adhered via the backsheet 6 in this region, the contraction force of the linear rubber 4F3 acts to contract the absorber 8 in the width direction, and therefore the outer cover is involved in the irregularities generated in the absorber 8, and there is a possibility that the linear rubber 4F3 cannot be visually confirmed from the outside at this position. In the present embodiment, since the non-adhesive region 15 is provided, the linear rubber 4F3 can be visually confirmed from the outside.

Fig. 5 is a schematic view of the diaper according to embodiment 1 when the trunk opening 2T is opened and viewed from the trunk opening 2T side. The side sheets 10L, 10R forming the three-dimensional gathers 3BR, 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. The side sheets 10L and 10R are bonded to the left and right end sides of the top sheet 9 in the width direction by a hot melt adhesive. The side sheets 10L, 10R are folded outward on the inner side in the width direction of the diaper 1 than the fold-back lines 10L2, 10R2, and have free ends 3BL1, 3BR1 at the distal ends. The side sheets 10L, 10R have linear rubbers 10L1, 10R1 disposed on the free ends 3BL1, 3BR1 side, and leak-proof walls rising from the fold-back lines 10L2, 10R2 toward the wearer are formed by contraction of the linear rubbers 10L1, 10R 1.

Here, at least one of the 3 linear rubbers 10L1, 10R1 is different in color from the exterior body. For example, the outer 1 of the 3 linear rubbers 10L1, 10R1 may be of a different color from the outer body. The diaper 1 can widely open the left and right leg openings 2L, 2R on the front region 1F side by contracting the outer body at the crossing portion of the linear rubber 4F3 by contracting the linear rubber 4F 3. Thus, when the left and right lower limb openings 2L, 2R are visually confirmed from the front body region 1F side, the three-dimensional gathers 3BL, 3BR can be visually confirmed, and the linear rubbers 10L1, 10R1 can also be visually confirmed. By providing the linear rubber 10L1 with a different color from the outer body, the diaper 1 can be recognized that the linear rubber 10L1 of a different color is visually recognized as being on the front side from the left and right lower limb openings 2L, 2R, and thus can be easily recognized as being on the back and forth side.

Here, as described above, the whole of the linear rubber 4F3 is colored (for example, blue, red, etc.) other than white, and the whole of the linear rubber 4R3 is white as in the case of the exterior body. The linear rubbers 10L1 and 10R1 are colored (for example, blue, red, etc.) other than white as a whole, and the linear rubbers 10L1 and 10R1 and the linear rubber 4F3 are the same color. The linear rubbers 10L1, 10R1 extending in the front-rear direction (longitudinal direction) and the linear rubber 4F3 forming the front leg gathers 3LF are the same color, and the linear rubbers 10L1, 10R1 and the linear rubber 4F3 of the same color appear to cross when the diaper 1 is viewed from the trunk opening 2T. Accordingly, when the wearer inserts the legs into the left and right lower limb openings 2L and 2R of the diaper 1, the wearer can recognize the appearance as: the side where the linear rubbers 10L1, 10R1 and the linear rubber 4F3 having different colors from the outer body and intersecting each other are arranged is the front side. This makes it easy to distinguish the diaper 1 from each other in the front-rear direction.

Further, since the linear rubber 4F3 extends in the direction (width direction) intersecting the linear rubbers 10L1, 10R1 extending in the front-rear direction, the boundary between the linear rubbers 10L1, 10R1 and the linear rubber 4F3 can be easily visually checked, and the edges of the left and right lower limb openings 2L, 2R can be easily grasped when the wearer inserts the legs, and the legs of the wearer can be prevented from getting caught on the edges of the lower limb openings 2L, 2R.

The linear rubber 4R3 forming the rear leg gathers 3LR is the same color as each sheet of the outer body and the inner body. Specifically, the linear rubber 4R3 is white in color as the cover sheet 4, the inner cover sheet 5, the top sheet 9, and the side sheets 10L and 10R. As a result, when the diaper 1 is viewed from the trunk opening 2T, the linear rubber 4R3 is less visible than the linear rubber 4F3, and the wearer is concerned with the front side linear rubber 4F3. Generally, the colored and dark color is easier to visually confirm than the colorless (e.g., white) and light color, and therefore, the side of the linear rubber 4F3 disposed with a darker color than white is easily recognized as the front side by the wearer or the wearer of the diaper. This makes it easy to distinguish the diaper 1 from each other in the front-rear direction.

In addition, even if the edges of the left and right lower limb openings 2L, 2R are caught in the heel side of the wearer, the insertion of the leg lower limb openings 2L, 2R is not hindered, but if the edges of the left and right lower limb openings 2L, 2R are caught in the thumb of the wearer, the wearer may fall. Therefore, when the wearer wears the diaper by himself or herself, or when the wearer wears the diaper by a caregiver, attention is paid to avoid the edges of the left and right lower limb openings 2L and 2R from getting caught by the thumbs. In the diaper 1 according to the present embodiment, when the linear rubbers 10L1 and 10R1 provided on the inner sides of the left and right lower limb openings 2L and 2R in the width direction of the three-dimensional gathers 3BL and 3BR and the linear rubbers 4F3 intersecting the linear rubbers 10L1 and 10R1 are successfully visually checked, the positions where the linear rubbers 10L1 and 10R1 intersect the linear rubbers 4F3 can be recognized as the edges on the front sides of the left and right lower limb openings 2L and 2R, and therefore, the wearer and the carer can be made aware of the prevention of the thumb of the wearer from being caught on the edges. Further, since the side on which the colored linear rubber 4F3 is disposed is the front side of the diaper 1, the wearer and the caregivers can recognize the side on which the linear rubber 4F3 is disposed as the front side of the diaper 1, and thus the diaper 1 can be worn with the front and rear directions in a correct orientation.

As shown in fig. 3 and 4, a non-adhesive region 15 is provided in which the outer and inner members of the linear rubber 4F3 are non-adhesive at a portion that laterally crosses the absorber 8 on the non-skin surface side of the absorber 8. In the diaper 1, the non-adhesive region 15 is disposed on the non-skin surface side of the inner body, and the outer body of the portion where the non-adhesive region 15 is disposed is inflated to the outside (non-skin surface side), so that when the diaper 1 is viewed from the outside, it is easy to distinguish that the one of the inflation of the outer body is the front side. Thus, the diaper 1 can be easily distinguished from each other in the front-rear direction.

< embodiment 2>

Next, a diaper 1 according to embodiment 2 will be described. Fig. 6 is an example of an exploded perspective view of the diaper according to embodiment 2. 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. 6, a linear rubber 4F7 (an example of the "3 rd 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 from the front body region 1F to the crotch region 1B. 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 (telescopic member cover piece) 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 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 whole of the linear rubber cover sheet 13 is not 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 prevents the elastic force (contraction force) of the linear rubber 4F7 from being excessively applied to the absorber 8, and prevents the absorber 8 from being excessively deformed. In addition, when a band-shaped stretchable member is used instead of the linear rubber 4F7, the stretchable member and the core wrap 7 can be made non-adhesive at a part thereof 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. Further, a part of the linear rubber cover sheet 13 is not bonded to the absorber 8. The linear rubber cover sheet 13 may be non-bonded to the absorber 8 as a whole.

Fig. 7 is an example of a schematic view showing a state in which the diaper 1 according to embodiment 2 is developed and extended. Part (a) of fig. 7 schematically shows an internal configuration in the case where the diaper 1 in the developed and elongated state is viewed from the left side. Part (B) of fig. 7 is a plan view of the diaper 1 in an unfolded and extended state.

As shown in fig. 7, the linear rubber 4F7 is provided in a central portion in the width direction between the backsheet 6 and the core wrap sheet 7 in an elongated state in the longitudinal direction from the front body region 1F to the crotch region 1B. In practice, the linear rubber 4F7 is provided between the back sheet 6 and the linear rubber cover sheet 13. 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. 7. 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 portion on the precursor region 1F side. Such pressing of the absorber 8 is achieved by embossing with a roller, for example.

Next, the line 14 formed in the absorber 8 will be described with reference to fig. 8 to 9. Fig. 8 is a plan view showing the absorbent body 8 and a part of the linear rubbers 4F3, 4R3 drawn out from the diaper 1. Fig. 9 is a cross-sectional view of the diaper 1 taken at line IX-IX in part (B) of fig. 7 in the width direction.

As shown in fig. 8, the wire 14 has 4 slots. The 4 grooves are constituted by grooves 14AL, 14AR, and grooves 14BL, 14BR (an example of "a pair of left and right grooves" in the present disclosure). 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 front body region 1F side end in the region corresponding to the groin of the wearer from the widthwise center of the diaper 1 toward the outside. 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 non-adhesive region 15 is provided so as to overlap with the grooves 14AL and 14AR when the region in which the grooves 14AL and 14AR are provided is viewed in plan. If the non-adhesive region 15 is formed so as not to include the region overlapping the grooves 14AL, 14AR, and the absorber 8 is adhered to the inner cover sheet 5 in this region, the outer body is expanded to be in contact with 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 inguinal portion to a flat state acts on the absorber. In contrast, the diaper 1 according to the present embodiment is configured as described above, and the absorber 8 in a state of being folded along the groin portion can be held in a folded state and can be abutted against the skin surface side. This improves the close contact between the absorbent body 8 and the skin of the wearer in the diaper 1.

As shown in fig. 8, the non-adhesive region 15 extends in the width direction of the diaper 1 and has a substantially rectangular shape. In fig. 8, although not shown, the non-adhesive region 15 extends to the widthwise end of the inner body of the diaper 1. In the wearing state of the diaper 1, the absorber 8 can be 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 brought into contact with 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. 8, the diaper 1 includes 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. 7, the end portions of the linear rubber 4F3 are disposed at the width-direction end portions of the left and right lower limb openings 2L and 2R. By inserting the legs into the left and right 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 in this region, a non-adhesive region 15 where the absorber 8 and the outer body are non-adhesive is provided. Thus, the absorber 8 is lifted up by the outer body so as to approach the skin surface side while being kept in a state of being bent 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 the left and right, 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 portions 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, if the backsheet and the separate sheet are non-bonded in the non-bonded region 15, the diaper 1 can obtain the above-described effects.

Next, the grooves 14BL, 14BR will be described. The grooves 14BL and 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 formed therein, so that the absorber 8 between the grooves is in a state of bulging toward the urethral orifice side. Thus, the diaper 1 can bring the absorber 8 into contact with the urethral opening, and thus can improve the adhesion of the absorber 8 to the skin of the wearer.

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 bringing the absorber 8 into contact with the skin surface side of the wearer in a folded state by the linear rubber 4F3 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 having a shape bent by the grooves 14BL and 14BR can be lifted up toward the skin surface side by the linear rubber 4F3 without deforming the absorber 8 due to contraction of the linear rubber 4F3, and the absorber 8 can be brought into contact with the skin surface side. In order to achieve 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, and thereby the absorber 8 is brought into contact with 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 absorbent body 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 (urine pad) disposed on the top sheet 9 is preferably placed against the urethral orifice. The diaper 1 may be configured as follows: the linear rubber 4F3 is overlapped with the grooves 14AL, 14AR, and the linear rubber 4F3 is not overlapped with the grooves 14BL, 14BR, whereby the absorber 8 bent along the groin portion is suitably abutted against the skin surface side of the wearer by the contraction force of the linear rubber 4F 3. The diaper 1 may be configured as follows: 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, the absorbent body 8 is preferably brought into contact with the urethral orifice or the inner pad (diaper) disposed on the top sheet 9 is brought into contact with the urethral orifice. As in the present embodiment, the diaper 1 may be configured such that the linear rubber 4F3 overlaps the grooves 14AL and 14AR and the grooves 14BL and 14BR, and both of the above-described 2 suitable configurations may be adopted.

The grooves 14AL, 14AR and the grooves 14BL, 14BR are not limited to extrusion grooves. The grooves 14AL, 14AR and the grooves 14BL, 14BR may be formed by reducing the pulp order of the absorbent core 8c only in the groove forming portion, so long as the absorbent body 8 can be folded with the grooves as the starting points. In addition, by making the grooves 14AL, 14AR and the grooves 14BL, 14BR as extrusion grooves, the groove forming portion can be made highly rigid, and the deformation of the groove forming portion can be prevented.

In the present embodiment, the groove 14AL is connected to the groove 14BL, and the groove 14AR is connected to the groove 14 BR. Thus, the groove 14AL and the groove 14BL can be formed integrally, and the groove 14AR and the groove 14BR can be formed integrally. 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 grooves are spaced apart from each other, the end of the groove 14BL may not be disposed on the extension line of the groove 14AL, or the end of the groove 14BR may not be disposed 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 left and right 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. Thus, the absorber 8 is pushed 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, 14 BR. In this way, the diaper 1 can bring the absorber 8 into contact with the urethral orifice, and therefore, the adhesion of the absorber 8 to the skin of the wearer can be improved.

The grooves 14BL and 14BR can bend the absorber 8 in a W shape when the absorber 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 and 14BR are provided only in the region corresponding to the urethral orifice, and the absorber 8 is formed in a planar shape in a portion other than the groove forming region, the grooves do not function as bending means of the absorber 8. Thus, the groove needs to be extended longer than the region corresponding to the urethral orifice. Thus, 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. The diaper 1 according to the present embodiment can improve the close contact between the absorber 8 and the wearer's urethral opening by extending the grooves 14BL and 14BR to the anus corresponding region 30 and bending the absorber 8 in a W shape.

However, if the grooves 14BL, 14BR are formed in the anus corresponding region 30, and the absorber 8 is bent along the grooves 14BL, 14BR, the absorber 8 may be caught in the cleft (fissure) of the buttocks of the wearer. If the absorber is caught in the gluteal cleft of the wearer, the wearer feels a sense of compression, and the feces discharged from the wearer will come into contact with the skin surface around the gluteal cleft, and the sense of wearing will be reduced. Then, the diaper 1 according to the present embodiment includes a pair of linear rubbers 4R3 disposed on both sides in the width direction of the grooves 14BL, 14 BR. The linear rubber 4R3 pulls the absorber 8 outward in the width direction of the diaper 1. In this way, the diaper 1 prevents the absorber 8 from sinking into the gluteal cleft of the wearer by suppressing the absorber 8 of the anus corresponding region 30 from bending along the grooves 14BL, 14BR, and can suppress the deterioration of the wearing feeling.

The inner end portion in the width direction of the linear rubber 4R3 overlaps the grooves 14BL, 14BR when viewed in the thickness direction. By overlapping the grooves 14BL, 14BR and the linear rubber 4R3, the grooves 14BL, 14BR can be pulled outward in the width direction from immediately below the grooves 14BL, 14BR, and the widthwise cross-sectional shape of the absorber 8 in the anus-corresponding region 30 can be suppressed from becoming W-shaped, and the absorber 8 can be suppressed from sinking into the buttock-thigh grooves of the buttocks. By pulling the grooves 14BL, 14BR from directly below, a force acts in a direction of peeling the absorber 8 from the top sheet 9, so that the grooves 14BL, 14BR are easily deformed, that is, the rigidity (hardness) of the pressing grooves is reduced, and the force of deforming the absorber 8 into a W shape by the grooves 14BL, 14BR can be reduced in the anus-corresponding region 30.

The inner end portion of the linear rubber 4R3 in the width direction may be disposed outside the grooves 14BL, 14BR when viewed in the thickness direction. In contrast to pulling the grooves 14BL, 14BR from directly below, the adhesion between the absorbent body 8 and the skin-side material (e.g., the topsheet 9) at the portions of the grooves 14BL, 14BR is made difficult to peel, and peeling of the skin-side material is suppressed over the entire areas of the grooves 14BL, 14BR starting from the portions. This can prevent the absorber 8 from being deformed into a W-shape in the region corresponding to the urethral orifice by the grooves 14BL and 14 BR. Furthermore, it is possible to provide a device for the treatment of a disease. In this case, too, the vicinity of the grooves 14BL, 14BR is preferably pulled outward by the linear rubber 4R 3.

In the present embodiment, the grooves 14BL and 14BR are provided so as to include the urethral orifice corresponding region to the anus corresponding region 30. The rear ends of the grooves 14BL, 14BR are anus corresponding regions 30. If a groove is formed on the back side of the anus-corresponding region 30, a force may act on the front and rear sides of the anus-corresponding region 30 to deform the absorber 8 into a W-shaped cross section even if the absorber 8 is pulled outward in the width direction by the stretchable member. In the present embodiment, by disposing the rear end portions of the grooves 14BL, 14BR in the anus-corresponding region 30, it is possible to avoid a force deforming the absorber 8 into a W-shaped cross section in the front-rear direction of the anus-corresponding region 30 from acting on the absorber 8.

The linear rubber 4F7 is disposed in a region overlapping between 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 as the outer body, and pushes up the absorber 8 toward the skin surface side. Thus, the diaper 1 can lift the portion of the absorber 8 protruding toward the urethral orifice side between the pair of grooves 14BL, 14BR toward the skin surface side by the outer body. Since the diaper 1 can bring the absorber 8 into contact with the urethral orifice, the adhesion of the absorber 8 to the skin of the wearer can be improved.

The linear rubber 4F7 is disposed on the non-skin surface side of the absorber 8. The linear rubber 4F7 is provided at the widthwise central portion of the diaper 1, and the linear rubber 4F3 extends in the crotch region 1B so as to pass through the region corresponding to the urethral orifice. The linear rubber 4F7 has a color (for example, a color such as red or blue) different from that of the outer body and the absorber 8, and can be visually confirmed from the outside of the outer body, that is, the outside of the cover sheet 4. The diaper 1 according to the present embodiment can visually confirm the intersection point of the linear rubber 4F7 and the linear rubber 4F3 from the outside on the abdomen side and cannot visually confirm the intersection point on the back side, and thus can make the distinction between front and back easier. The linear rubber 4F7 may be bonded to the non-skin surface side of the absorber 8.

In the present embodiment, the grooves 14BL, 14BR overlap the linear rubber 4F3 when viewed in the thickness direction. Even when the absorber 8 is bent in a W shape along the grooves 14BL, 14BR, the non-adhesive region 15 is provided, so that the linear rubber 4F3 cannot be visually confirmed from the outside because the outer covering is not involved in the irregularities generated in the absorber 8.

When viewed in the thickness direction, the abdomen-side grooves 14AL, 14AR, 14BL, 14BR are provided so as to overlap the non-adhesive region 15. By providing the non-adhesive region 15, when the diaper is visually checked from the outside of the exterior body, the lines of the grooves 14AL, 14AR, 14BL, 14BR on the skin surface side of the non-adhesive region are hardly visible or are not visible. On the other hand, since the non-adhesive region is not provided on the back side, when the diaper is visually confirmed from the outside of the exterior body, the lines of the grooves 14BL, 14BR on the back side are easily visible or the lines are clearly visible. This makes it possible to easily distinguish the diaper 1 from each other in the front-rear direction.

The linear rubber 4F7 may be bonded to the absorber 8 without providing the linear rubber cover sheet 13 shown in fig. 6 and 9. This causes the absorber 8 to contract in the front-rear direction, and the absorber 8 in the region corresponding to the urethral orifice is easily deformed so that the cross section becomes W-shaped. The linear rubber 4F7 may be disposed in a region where the inner cover sheet 5 and the absorber 8 are bonded via the back sheet 6. In the case where the linear rubber 4F7 is provided in this way, the absorber 8 is easily deformed in a W shape, but in the present embodiment, the absorber 8 is prevented from being deformed in the anus-corresponding region 30 by pulling the absorber 8 outward by the linear rubber 4R 3.

The linear rubber 4F7 extends between the pair of left and right grooves 14AL, 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 lifted to 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, 14AR and between the grooves 14BL, 14 BR. As shown in fig. 7, the linear rubber 4F7 is not overlapped with the linear rubber 4F2 for abdominal puckering in the state where the diaper 1 is viewed in plan. With this structure, the diaper 1 forms a space between the crotch region 1B side of the abdominal gathers and the skin surface of the wearer, and urine in the lateral direction reaching the front body region 1F side (abdominal side) is likely to pass around 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 sexual organ facing either the left or right direction, urine tends to pass around the other in the left or right direction, and thus 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. With this configuration, the diaper 1 lifts the outer body toward the skin surface side by the contraction force of the linear rubber 4F7, and thereby lifts the portion of the absorber 8 protruding between the grooves 14BL, 14BR toward the skin surface side, but in the anus corresponding region 30, the lifting of the absorber 8 toward the skin surface side is suppressed. The diaper 1 can easily separate the anus from the skin surface side of the diaper 1.

< embodiment 3>

Next, a diaper 1 according to embodiment 3 will be described. Fig. 10 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 will be omitted.

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. 10, the absorbent core 8c has an upper absorbent pad 8a and a lower absorbent pad 8b. The upper layer absorbent pad 8a has a substantially hourglass shape with narrowed portions, and the lower layer absorbent pad 8b has a rectangular shape. 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 central portion. In this way, the absorbent core 8c may be formed by stacking 2 layers of absorbent pads.

< other modifications >

The present embodiment has been described above, but the content of the present utility model is not limited to the above embodiment. In the above embodiment, the underpants type disposable diaper has been described as an example, but the present utility model is not limited to this, and the present utility model can be applied to an absorbent article such as a belt type disposable diaper.

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 and 8. In this case, the absorber 8 can be prevented from being displaced from the inner cover sheet 5. The partial bonding portion may be, for example, a widthwise central portion.

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.
