  In the pants-type wearing article disclosed in Patent Document 1, the width of the absorbent body is increased in order to ensure a sufficient amount of absorption of bodily fluid, and even if the absorbent absorbs bodily fluid after excretion and the weight increases, the position is increased. The vertical dimension around the waist was formed larger than that of the body so as not to slip. However, when such a wearing article is worn, when the leg opening becomes relatively small, the leg tip may get caught in the leg opening, or the upper end of the diaper may protrude from the upper end of clothing such as underwear. . In addition, the crotch part is stiff, part of it is bent, and a stepped outer shape line appears on the clothes, so that another person may recognize that he is wearing a diaper in appearance. Especially for female wearers who wear diapers for light incontinence for the first time, it may be difficult for them to wear them, and they may make it difficult for others to know that they are wearing diapers. May feel resistance.

  An object of the present invention is an improvement of the prior art, which is provided with a relatively slim liquid-absorbent core and can temporarily diffuse and retain body fluids in excess of the water retention capacity of the liquid-absorbent core. An object of the present invention is to provide a pants-type wearing article for adults that women can wear without resistance.

  The present invention has a longitudinal direction and a lateral direction, and is located between a front waist panel that forms a front waist region, a rear waist panel that forms a rear waist region, and a front and rear waist panel, and forms the crotch region. The present invention relates to a pants-type wearing article for adults including an absorbent panel having an absorber.

Various known fiber nonwoven fabrics such as a spunbond fiber nonwoven fabric of ~ 0.1 g / cm ³ , an SMS (spunbond / meltblown / spunbond) fiber nonwoven fabric, and an air-through fiber nonwoven fabric can be used.

  In the front and rear waist elastic bodies 20 and 23, as the front and rear upper waist elastic bodies 20A and 23A, for example, the fineness is about 600 to 1200 dtex, and the front and rear waist elastic bodies 20 and 23 can be contracted in an extended state about 2.5 to 3.5 times. An arranged string-like or strand-like elastic material can be used. Further, as the front and lower waist elastic bodies 20B and 23B, for example, a string shape or a strand having a fineness of about 400 to 800 dtex and arranged to be contractable in a state of being stretched about 1.5 to 3.0 times An elastic material can be used. It is preferable that the extension stress of the stretchable region where the front lower waist elastic body 20B is disposed is higher than the stretch stress of the stretchable region where the rear lower waist elastic body 23B is disposed.

  Various conditions such as the fineness of the front and rear waist elastic bodies 20 and 23, the expansion ratio, and the separation dimension (pitch) between the elastic bodies can be appropriately changed as necessary. In order to be worn stably, the condition of each elastic body is such that the stretching stress in the stretchable region by the front and back waist elastic bodies 20A and 23A is higher than the stretching stress in the stretchable region by the front and bottom waist elastic bodies 20B and 23B. Is preferably set. Moreover, as long as a required elastic force can be applied to the front and rear waist regions 11 and 12, instead of or along with the front and rear waist elastic bodies 20 and 23, the elastic elastic sheet is attached to the inner surface side of the front and rear waist regions 11 and 12, or You may arrange | position to an outer surface side. By arranging the front and rear waist elastic bodies 20, 23 on the entire outer surface of the diaper 10, a plurality of gathers are formed on the outer surface and gathered as a whole.

  The absorbent panel 16 has a vertical rectangular shape defined by front and rear end edges 16a and 16b and both side edges 16c and 16d, and the front and rear end portions 19A and 19B are formed on the skin facing surfaces of the front and rear waist panels 14 and 15, for example. They are joined to each other via a front and rear joining region (not shown) formed by applying a hot melt adhesive. As the application pattern of the hot melt adhesive in the front-rear joining region, for example, various known shapes such as an Ω shape, a spiral shape, and a wave shape can be adopted in addition to a plurality of line shapes extending in the longitudinal direction Y.

  Referring to FIGS. 2 to 4, the absorbent panel 16 includes a liquid absorbing structure 30 composed of a hydrophilic / liquid permeable inner surface sheet (body side liner) 31 and an absorbent body 33 located on the skin facing surface side. A hydrophobic coating sheet 32 positioned on the non-skin facing surface side of the liquid absorbing structure 30, and a hydrophobic or hydrophobic sheet having a size covering at least the bottom surface on the non-skin facing surface side of the liquid absorbing structure 30. And a liquid-impervious leak-proof plastic film 34. The absorber 33 includes a liquid absorbent core 35 and a core cover sheet 36 that covers the entire liquid absorbent core 35.

  The liquid-absorbent core 35 has a semi-rigid panel shape shaped into a required shape, and extends toward the longitudinal center line P between the front and rear end edges extending in the lateral direction X and the front and rear end edges (lateral direction X And both side edges 35c and 35d extending in a convex manner. The liquid absorbent core 35 includes wood fluff pulp and superabsorbent polymer particles (SAP) commonly used in the industry. When the wearing article 10 is used as a diaper for adults and light incontinence, it is preferable that the thickness of the liquid-absorbent core 35 is relatively small. For example, the mass of SAP is changed to the mass of wood fluff pulp. On the other hand, by making it relatively small, the thickness dimension may be reduced while maintaining a required water absorption amount, or the liquid-absorbing core 35 may be formed only from SAP.

The inner surface sheet 31 and the core cover sheet 36 are formed from a sheet material having lyophilicity (hydrophilicity) and liquid diffusibility, and examples of the material include a mass of about 15 to 25 g / m ^2. Spunbond fiber nonwoven fabrics, SMS fiber nonwoven fabrics, and the like that have been hydrophilized can be used. The material of the core cover sheet 36 may be the same type of sheet material as the inner surface sheet 31, but is preferably tissue paper. Moreover, the thickness dimension should just be a thickness dimension which implement | achieves the intensity | strength which is small compared with that of the inner surface sheet 31, and can hold the liquid-absorbing core 35 in a required shape. The covering sheet 32 is formed from a hydrophobic or substantially liquid-impervious sheet material, and is formed from, for example, an SMS fiber nonwoven fabric or a spunbond nonwoven fabric having a mass of about 15 to 30 g / m ² . The leak-proof film 34 is preferably formed from a hydrophobic sheet material having air permeability, for example, a moisture-permeable plastic film having a mass of about 10 to 25 g / m ² .

  In the liquid absorbing structure 30, the inner surface sheet 31 extends further outward in the lateral direction X from both side edges 35 c and 35 d of the liquid absorbing core 35. Specifically, the inner surface sheet 31 that covers the skin facing surface side of the liquid-absorbent core 35 is along a bent line (not shown) extending in the longitudinal direction Y along both side edges 16c and 16d of the absorbent panel 16. The outer edge 31b is located on the non-skin facing surface side of the liquid absorbent core 35. The core cover sheet 36 that encloses the liquid-absorbent core 35 has an outer shape that is slightly larger than the external dimensions of the liquid-absorbent core 35. The inner surface sheet 31 and the core cover sheet 36 have extended portions 31A and 36A extending from both side edges 35c and 35d of the liquid-absorbent core 35 to the outside in the lateral direction, respectively, and by these extended portions 31A and 36A, A hydrophilic layer (liquid absorbing layer) 50 is formed outside the liquid absorbing core 35 in the lateral direction X.

  The hydrophilic layer 50 has a four-layer structure because it is formed from the extended portions 31 </ b> A and 36 </ b> A formed by folding the inner surface sheet 31 and the core cover sheet 36. However, as long as it has the required liquid retention performance, the extending portion 31A of the inner surface sheet 31 and the extending portion 36A of the core cover sheet 36 may have a single-layer structure instead of a two-layer structure, or may be hydrophilic. The layer 50 may be formed only from the extending portion 31 </ b> A of the inner surface sheet 31. Further, since both side edges 35c and 35d of the liquid-absorbent core 35 are concavely curved, the hydrophilic layer 50 has the largest dimension in the lateral direction X in the central portion of the crotch region 13, and the front and rear waist regions 11 and 12, the dimension is the smallest.

  By having such a configuration, the absorbent panel 16 has a pair of leak-proof cuffs 60 extending in the vertical direction Y, and a pair of side extension portions (gasket cuffs) 61 positioned outside the leak-proof cuff 60 in the lateral direction X. including. The leak-proof cuff 60 is fixed to the inner surface sheet 31 via the inner joint region 47 and the both-end fixing portion fixed to the inner surface sheet 31 via the end joint region 48 of the both side portions 42 of the covering sheet 32. A base end portion (proximal portion) 62 extending in the vertical direction Y, and a free portion (distal portion) 63 extending in the vertical direction Y between the both end fixing portions and extending in the vertical direction Y in parallel with the base end portion 62. And have. A cuff elastic body 64 is disposed in the free portion 63 so as to be contracted in an extended state. When the cuff elastic body 64 contracts in the wearing state, the edge portion is separated from the inner surface sheet 31 toward the wearer's body, and fits the wearer's thigh to prevent leakage of excrement.

  In the present embodiment, the leak-proof cuff 60 and the side extension 61 are formed from the cover sheet 32, but the leak-proof cuff 60 may be formed from a sheet material separate from the cover sheet 32. In such a case, the leak-proof cuff 60 mainly prevents leakage of excrement and therefore does not necessarily need to be formed from a liquid-impermeable sheet. Moreover, you may use an elastic elastic sheet as the free part 63 or the cuff elastic body 64 of the leak-proof cuff 60. FIG. The covering sheet 32 is bent toward the non-skin-to-rear side of the liquid absorbing structure 30, the main body portion 41 where the liquid absorbing structure 30 is disposed, both side portions 42 positioned on both sides in the lateral direction X of the main body portion 41. And an outer edge 42A.

  The side extension 61 of the absorbent panel 16 includes a hydrophilic layer 50 composed of an extension part 31A of the inner surface sheet 31 and an extension part 36A of the core cover sheet 36, and the hydrophilic layer 50 in the thickness direction Z. It has the hydrophobic layers 51 and 52 to cover. The hydrophobic layers 51 and 52 are a first hydrophobic layer (lower layer) 51 that covers the non-skin facing surface side of the hydrophilic layer 50 and a second hydrophobic layer that covers the skin facing edge side of the hydrophilic layer 50. (Upper layer) 52. The first hydrophobic layer 51 has a three-layer structure including a main body portion 41 of the covering sheet 32, an outer edge portion 42 </ b> A, and a leak-proof film 34, and the second hydrophobic layer 52 is formed on both sides of the covering sheet 32. It has a two-layer structure composed of part 42. Between the side edge part of the leak-proof film 34 which forms the 1st hydrophobic layer 51, and the outer edge part 42A of the coating sheet 32, the multiple leg | leg elastic body 65 is attached so that contraction is possible in the expansion | extension state. . The side extension 61 of the absorbent panel 16 has elasticity in at least the longitudinal direction Y due to the contracting action of the leg elastic body 65 located in the first hydrophobic layer 51.

  In the wearing state of the diaper 10, the leak-proof cuff 60 stands up toward the wearer's body due to the contraction action of the cuff elastic body 64, and the side extension 61 extends from the thigh by the contraction force of the leg elastic body 65. It is fitted near the base. As described above, the leg opening edge of the diaper 10 is brought into contact with the body in a relatively wide range by the leak-proof cuff 60 and the side extension portion 61, so that the side leakage of excrement is caused by the leak-proof cuff 60 alone. As compared with the case of preventing the excrement, the side leakage of excrement can be prevented more effectively.

  The side extending portion 61 includes a first hydrophobic layer 51 that covers the non-skin facing surface side of the hydrophilic layer 50 and a second hydrophobic layer 52 that covers the skin facing surface side of the hydrophilic layer 50. In the hydrophilic layer 50, it is possible to suppress the body fluid that has diffused and absorbed to both side edges from leaking to the outside. Further, in the side extension portion 61, the first and second hydrophobic layers 51, 52 are formed by bending the covering sheet 32 so as to cover the entire hydrophilic layer 50, and the lateral direction of the hydrophilic layer 50 Since the hydrophobic layer is located outside X, body fluid does not leak to the outside.

  The conventional diaper 110 has dimensions of an average adult diaper, and is a dimension in the longitudinal direction Y from the upper end edge 114b to the lower end edge 114a of the front and rear waist panel 114 in a non-stretched state. One dimension (vertical dimension of the upper portion 181) M1 is 150 to 170 mm. Further, a second dimension (lower part) that is a distance dimension from the lower end edge 114a of the front waist panel 114 to the lowermost end of the absorbent panel 116 (point T2 on the transverse center line that bisects the longitudinal dimension of the entire diaper 110). 182 (vertical dimension) M2 is 140 to 150 mm, and the third dimension M3, which is the length dimension in the lateral direction X of the lower panel edge 114a of the front waist panel 114 that overlaps the absorbent panel 116 (overlapping part), is 140 to 150 mm. 160 mm, a fourth dimension (leg) that is a dimension in the lateral direction X of one non-overlapping portion of the pair of non-overlapping portions located outside the overlapping portion of the lower end edges 114a of the front and rear waist panels 114 (Dimension of opening) M4 is 80 to 90 mm. The first dimension M1 and the second dimension M2 were measured along a longitudinal center line J that bisects the lateral dimension and extends vertically from the upper edge 114b to the lower edge 114a.

  Referring to FIG. 7 (a), a typical underwear 210 for women has front and rear waist regions 211, 212 and a crotch region 213, and the waist opening edge portion and the leg opening edge portion are the underwear body. Separate elastic sheets 220 and 221 are attached to be stretchable. The underwear 210 has an upper portion 281 extending from the upper end edge 214b of the front waist region 211 to the upper end edge of the leg opening, and a lower portion 282 located below the upper portion 281 in front view. Here, in the underwear 210, the lower end edge of the front waist region 211 means the lower end edge 214a that connects the upper ends of the pair of leg openings.

  In the underwear 210, the first dimension (vertical dimension of the upper portion 281) N1 that is a longitudinal dimension from the upper end edge 214b to the lower end edge of the front waist region 211 in a non-stretched state is 100 to 120 mm. A second dimension (vertical dimension of the lower portion 282) N2 that is a separation dimension from the lower end edge to the lowermost end of the crotch region 213 (a point T3 on the transverse center line that bisects the longitudinal dimension of the entire underwear 210) is: The dimension N3 in the lateral direction X of the portion located at the boundary with the crotch region 213 of the lower end edge of the front waist region 211 is 130 to 150 mm, and the width of the portion located outside the lateral direction X of the portion is 110 to 160 mm. The dimension in the direction X (width dimension of the leg opening) N4 is 72 to 88 mm. The first dimension N1 and the second dimension N2 were measured along a longitudinal center line J extending vertically from the upper end edge 214b to the lower end edge 214a, which bisects the lateral dimension.

  In recent years, there are an increasing number of clothes such as underwear and clothes that are relatively shallow on the crotch and that are worn mainly by women with their upper ends hooked on their hips. On the other hand, conventional pants-type diapers are designed with a relatively large vertical dimension in the waist area, and when wearing low-rise clothing, some of them may protrude from the clothing from above. was there. In addition, when the width of the crotch area of the diaper is relatively large, the inseam is stiff and uncomfortable, and a part of the crotch area is folded or folded and a stepped outline appears on the surface of the clothing, There is a risk that it is recognized that a diaper is worn in appearance. For younger women (40s-60s) who prefer low-rise clothing, such as wearing diapers for the first time for light incontinence, when they wear it, some of the diapers from low-rise clothing It has become a psychological burden to let other people know that a diaper is worn by protruding or forming a stepped outer shape line on the surface of clothing. Therefore, there is a demand for a diaper having a feeling of wearing such as an underwear, in which even when wearing a low-rise type garment, a part of the crotch is protruded or the inseam is stiff and a step-shaped outer shape line is not formed. .

  Referring to FIG. 7A, in the measurement of the doll 91 with the undergarment 210 pierced, the separation dimension R3 between the wall surface 90 and the closest position U3 is 18 mm, and a part of the undergarment 210 is seen from above the garment 92. It did not protrude. As described above, in the state where the garment 92 is attached to the doll 91 having the underwear 210 on, the underwear 210 is fitted to the doll 91, so that the doll 91 of the underwear 210 is not fitted to the back side. The raised portion is doubled to form a step and does not protrude rearward, giving an overall slim impression. When the underwear 210 is attached, the reason why a part of the underwear 210 does not protrude from above the garment 92 is that the first dimension N1 is smaller than the second dimension N2 in the underwear 210, so that the overall is a low-rise type. It can be considered to have a shape. In addition, since the total dimension of the first dimension N1 and the second dimension N2 is 230 to 270 mm, the lower portion 282 of the underwear 210 does not tab in the low-rise type garment 92 having a crotch dimension of 210 mm. It is considered that a step or the like due to a portion that fits on the doll 91 and is dubbed on the surface of the garment 92 is not formed. In addition, the applicant has performed the same measurement on a plurality of underwear 210 having different sizes, and as a result, when the total dimension of the first dimension N1 and the second dimension N2 is within a range of 250 to 290 mm. It has been found that the lower portion 282 does not fit on the doll 91 and does not rub.

  Therefore, the diapers 10 and 110 have a low-rise type shape like the underwear 210, and the lower portions 82 and 182 are not tabbed in the garment 92, the first dimensions L1 and L1 of the diapers 10 and 110, respectively. It is considered that M1 is smaller than the second dimensions L2 and M2, and the total dimension of the first dimensions L1 and M1 and the second dimensions L2 and M2 needs to be within a range of 250 to 290 mm.

  In the conventional diaper 110, the first dimension M1 is the first dimension M1 that is the vertical dimension of the upper portion 181 that is the front waist region 111 and the second dimension M2 that is the vertical dimension Y of the lower portion 182. Is smaller than the second dimension M2, and the first dimension M1 + the second dimension M2 is at least 290 mm or more. Referring to FIG. 6 (b), in the doll 91 in which the conventional diaper 110 is worn, a lower portion 182 that is doubling on the back side of the garment 92 appears in a stepped shape on the surface, and protrudes backward. It is an aspect. Therefore, the separation dimension R2 of the position U2 closest to the wall surface 90 of the doll 91 is 5 mm. In addition, since the first dimension M1 is larger than the second dimension M2, a part 110A of the diaper 110 protrudes from above the clothing 92. As described above, the conventional diaper 110 does not fit the doll 91, and the lower portion 182 is doubled on the back side so that the entire diaper 110 does not give a clean impression as a whole, and a part 110 </ b> A protrudes from the garment 92. Depending on the situation, the appearance may be greatly impaired.

  On the other hand, in the diaper 10 according to the present embodiment, in the first dimension L1 that is the vertical dimension of the upper portion 81 formed of the front waist region 11, and the second dimension L2 that is the dimension in the vertical direction Y of the lower portion 82. The first dimension L1 is smaller than the second dimension L2, and the first dimension L1 + the second dimension L2 is in the range of 250 to 290 mm. Referring to FIG. 5 (b), in the doll 91 in which the diaper 10 is worn, the separation dimension R1 between the wall surface 90 and the wall surface 90 at the closest position U is 15 mm, and the lower portion on the back side of the garment 92. 82 did not sag, and no step was formed by the lower portion 82. Further, a part of the diaper 10 did not protrude from above the clothing 92. In this way, when the diaper 10 is fitted to the doll 91, the portion of the garment 92 that has been dubbed does not appear as an outline line, and a clear impression is given, and a part of the diaper 10 is removed from the garment 92. It does not protrude and damage the appearance.

  In addition, the underwear 210 is designed so that the leg opening has a relatively large width dimension so that the leg can be easily inserted through the leg opening when worn, even in a non-extended state. The fourth dimension N4 which is the width dimension of the opening has a size of about 45 to 80% of the third dimension N3 which is the width dimension of the crotch portion. In the diaper 10, the fourth dimension L4 is about 45 to 80% of the third dimension L3, and it can be said that the leg is easily inserted into the leg opening when the diaper 10 is worn, like the underwear 210. According to the applicant's knowledge, when the fourth dimension N4 is 45% or less of the third dimension N3, the leg opening is relatively narrow and it is difficult to insert the leg. On the other hand, when the size ratio is 80% or more, the leg opening becomes too large, and the crotch portion is relatively narrow, so that it may bite into the body during wearing.

  In addition, since the diaper 10 according to this embodiment is mainly intended for light incontinence of adults, the absorbent body 33 positioned on the absorption panel 16 is thinner than a diaper that is not used for light incontinence, and its diaper Even when the amount of water is relatively low and the body fluid is diffused throughout the absorber 33, the crotch portion does not hang downward due to its own weight. Specifically, the water retention amount of the absorber 33 is 150 to 400 g. On the other hand, in the conventional diaper 110, the absorbent body is relatively thick, the water retention amount is 500 to 1200 g, and the body part is diffused throughout the absorbent body. Since it becomes the distortion shape which hangs down, there exists a possibility that the external shape of the conventional diaper 110 may appear more clearly in the external appearance of the clothing 92. In addition, in the case of a general elderly person, the amount of urination at a time is about 100 to 200 g, and the diaper 10 can sufficiently absorb and hold the amount of urination.

<Measurement method of water retention amount of absorber>
First, both side edges where the side seam 25 is located are cut out from the diaper 10 and the front and rear waist elastic bodies 20 and 23 and the leg elastic body 65 are cut so that the contraction force of each elastic body is not applied. Get a sample. Next, the weight of the sample was measured (E), and the entire sample was immersed in physiological saline (0.9% NaCl solution) poured into a plate-like container for 30 minutes. Next, after 30 minutes had elapsed, both sides of the waist end of the sample were left on the clip fixed to the heel and left standing for 10 minutes. Finally, the weight (F) after putting the sample in the dehydrator (150G) and dehydrating for 90 seconds was measured. The water retention amount of the absorber was determined by the formula F (g) -E (g). In addition, about the conventional diaper 110, the water retention amount was calculated | required with the same measuring method.

  Moreover, in the diaper 10 of this embodiment, it is preferable that the extension stress of the expansion / contraction area | region where the back lower waist elastic body 23B is arrange | positioned is lower than the extension stress of the expansion / contraction area | region where the front lower waist elastic body 20B is arrange | positioned. The rear end portion 19B and the front end portion 19A of the absorbent panel 16 intersect with the front and rear lower waist elastic bodies 20B and 23B, and the size of the rear end portion 19B is reduced by the contraction force. Since the lateral dimension of the rear end part 19B becomes smaller than the lateral dimension of the front end part 19A, it is possible to cover the entire buttocks against the wearer before wearing. And it can be made to recognize visually that the bodily fluid excreted by the back waist area 12 side can fully be absorbed and held, and a sense of security can be given. Moreover, since the lateral dimensions of the front and rear end portions 19A and 19B seen through the front and rear waist panels 14 and 15 are different, the front and rear of the diaper 10 can be easily identified. Further, since the front end portion 19A seen through is narrower than the rear end portion 19B and the dimension in the lateral direction X of the absorbent panel 16 is relatively small, the diaper 10 has a clean impression when viewed from the front. Can be given. Therefore, even when the wearer wears a garment that fits the body, the outer shape of the diaper 10 is not clearly seen from above the garment, and the wearer wears the diaper 10 for the first time. It is possible to reduce a sense of resistance to doing.

<Measurement method of stretching stress in stretch zone>
The elongation stress in each stretch region was measured by the following method using a tensile tester (manufactured by Shimadzu Corporation). First, in the diaper 10 (M size of a normal adult diaper, the lateral dimension W1 is 600 mm), the seam 25 is peeled to separate the front and rear waist panels 14 and 15, and the front and rear waist panels 14 and 15 are separated. After the front and rear end portions 19A and 19B of the absorbent panel 16 joined to the inner surface with an adhesive are removed from both the waist panels 14 and 15, the front and lower waist elastic bodies 20B and 23B are respectively extended from the front and rear waist panels 14 and 15. Each stretched area was cut out with a width of 140 mm to obtain each sample. Next, in a state where one end of the sample is held by the movable jig (upper chuck) and the other end is held by the fixed jig (lower chuck), the distance between the chucks is 300 mm and the speed of the movable jig is 300 mm. The distance between chucks is separated up to 425 mm, the movement is reversed, and the distance between chucks is brought close to 300 mm, and then the movement is reversed again until the distance between chucks is 425 mm. The elongation stress (N) at the time of being made was measured.

  As a result of the measurement, the extension stress of the stretch region where the rear lower waist elastic body 23B is arranged is about 16 N / m, and the extension stress of the stretch region where the front lower waist elastic body 20B is arranged is about 21 N / m. . As a result of the same measurement method, in the L size diaper 10, the former is about 3.5 N / m, the latter is about 10 N / m, and in the XL size diaper 10, the former is about 18 N / m and the latter is about 23 N. / M.

  In the conventional diaper 110, since the front lower waist elastic body 120B is cut and removed in the region where the front end portion 119A of the absorbent panel 116 is present, the technical effect of the diaper 10 cannot be obtained. In the conventional diaper 110, the front lower waist elastic body 120B intersects the front end portion 119A of the absorbent panel 116, and the rear lower waist elastic body disposed on the rear waist panel intersects the rear end portion of the absorbent panel 116. However, when they have the same elongation rate, the same effect as the diaper 10 cannot be obtained.

  Referring to FIG. 2 again, as described above, both side edges 35c and 35d of the liquid-absorbent core 35 have a shape that is curved inward in the lateral direction X, and are prevented at the center of the crotch region 13. It is farthest from the base end 62 of the leakage cuff 60. The liquid absorbent core 35 is semi-rigid, which is higher in rigidity than the sheet member, and when the liquid absorbent core 35 is positioned in the vicinity of the base end portion 62, the base end portion 62 is raised by the influence of the rigidity. However, since the base end 62 and the liquid-absorbent core 35 are farthest apart from each other in the central portion of the crotch region 13 where body fluid is most accumulated, standing of the leak-proof cuff 60 is inhibited. No, it is possible to prevent side leakage of body fluid.

  Further, in the present embodiment, the outer joint region 46 located in the side extension portion 61 and the inner joint region 47 that forms the base end portion 62 of the leak-proof cuff 60 are separated from each other in the lateral direction X. As described above, the outer joint region 46 and the base end portion 62 are separated from each other, so that the side extension portion 61 and the leak-proof cuff 60 are not affected by the mutual expansion and contraction action, and are independent. You can stand up. However, as long as the side extension part 61 and the leak-proof cuff 60 stand up independently of each other, the outer joining area 46 and the inner joining area 47 are made continuous in order to simplify the manufacturing process of the diaper 10. It may be applied to the covering sheet 32.

  Referring to FIG. 4 again, since the amount of water retained by the absorbent body 33 is relatively small, the absorbent body 16 is relatively thin, and the side panel having a multilayer structure on both sides of the absorbent panel 16 where the leg elastic bodies 65 are disposed. Since the protruding portion 61 is positioned, the thickness dimension of both side portions of the absorbent panel 16 is larger than the thickness size of the central portion. Specifically, the thickness D1 of the central portion of the absorption panel 16 is about 2.0 to 4.0 mm, and the thickness D2 of both sides is about 5.0 to 7.0 mm. Here, the central portion of the absorbent panel 16 is a region where the absorber 33 is disposed, and means a portion located between both side portions (portions where the side extension portions 61 are disposed), and at least longitudinally cut. It means a region including a point where the center line P and the transverse center line Q intersect.

  Thus, since the thickness dimension D2 of the both side parts of the absorption panel 16 is larger than the thickness dimension D1 of the center part, the leak-proof cuff 60 is laid on the skin facing surface side of the front and rear waist regions 11 and 12. Since the space surrounded by both sides is formed between the body and the central portion of the absorbent panel 16 at the front and rear end portions 19A and 19B, the air is flown, so that the inside of the diaper 10 is prevented from being steamed. Can do. In addition, the underwear 210 is attached to the leg opening edge with an elastic sheet 221 that is separate from the underwear main body, so that the thickness dimension of the leg opening edge is larger than the thickness dimension at the center of the crotch region. . Specifically, the thickness dimension of the center part of the crotch region is 0.8 to 1.2 mm, and the thickness dimension of the leg opening edge is 1.2 to 1.9 mm. Therefore, since both the diaper 10 and the underwear 210 are thicker at the leg opening edge than the center portion in the crotch region, it can be said that the diaper 10 is easily adapted to the underwear and easily adapted to its movement.

  On the other hand, in the conventional diaper 110, since the water retention amount of an absorber is comparatively large, it is comparatively thick and does not have a structure like the side extension part 61 of the diaper 10. In the absorption panel 116, the thickness dimension of the central portion of the crotch region 113 where the absorber is disposed is larger than the thickness dimension of both side portions located on both sides in the lateral direction of the central portion where the absorber is not disposed. It has become. Specifically, the thickness dimension of the central part in the crotch region 113 of the absorption panel 116 is 7.0 to 10.0 mm, and the thickness dimension of both side parts is 1.0 to 3.0 mm. Thus, in the conventional diaper 110, unlike the underwear 210, since the center part of the absorption panel 116 is thicker than both sides, it can be said that it is hard to adjust to the underwear 210 and to adapt to the movement.

  In the case of a diaper for adults, in order to minimize the thickness of the diaper 10 from the viewpoint of preventing the appearance of wearing a diaper on the inside of the clothes in daily life, It is preferable to reduce the thickness dimension and / or the width dimension of the conductive core. However, when the thickness dimension of the liquid-absorbent core is reduced, the amount of the body fluid absorbed may decrease, and the body fluid may not be sufficiently retained. The diaper 10 according to the present embodiment includes an extending portion 31 </ b> A of the inner surface sheet 31 and an extending portion 36 </ b> A of the core cover sheet 36 that extend outward in the lateral direction X from both side edges 35 c and 35 d of the liquid absorbent core 35. Since the hydrophilic layer 50 thus formed extends to the side extending portions 61 along the side edges 16c and 16d of the absorbent panel 16, the body fluid absorbed in the liquid absorbent core 35 in the hydrophilic layer 50 is absorbed. The body fluid that has diffused or has not been absorbed into it can be directly absorbed, and the body fluid that exceeds the liquid absorption amount of the liquid absorbent core 35 can be temporarily retained. Further, since the side extension 61 is stably brought into contact with the body, both side edges of the crotch region 13 are not sandwiched between the cracks during wearing, and the buttock is not exposed.

<Measurement method for thickness of absorbent panel>
The thickness dimension D1 of the center part of the absorption panel and the thickness dimension D2 of both side parts were measured by a thickness meter (PEACOCK DIAL THICKNESS GAUSE diameter 50 mm, measurement pressure 3 g / cm ² ).
