FIG. 8 is a cross-sectional view (corresponding to FIG. 3) showing still another embodiment of the male incontinence pad of the present invention.

  The present invention will be described below based on preferred embodiments with reference to the drawings. The incontinence pad 10 of the embodiment shown in FIGS. 1 and 2 is preferably used as, for example, a male incontinence pad, and is a vertically long one having a longitudinal direction X and a width direction Y orthogonal thereto. The male incontinence pad 10 has a central area C located at the center along the longitudinal direction X thereof. Moreover, it has the front area A and the back area B which each extend before and after the longitudinal direction X from the center area C. The front area A is a part located on the abdomen side of the wearer in the state where the male incontinence pad 10 is worn. The rear region B is a part located on the back side of the wearer in the state where the male incontinence pad 10 is worn. The central area C is located at the center when the male incontinence pad 10 is divided into three equal parts along the longitudinal direction. The front area A and the rear area B are portions that are adjacent to the central area C and located at end portions along the longitudinal direction X when the male incontinence pad 10 is divided into three equal parts along the longitudinal direction. .

  A top sheet 11, a back sheet 12, and an absorber 13 are provided. The top sheet 11 is located on the surface facing the wearer's skin when the male incontinence pad 10 is worn. The back sheet 12 is located on the side far from the wearer's skin when the male incontinence pad 10 is worn. The top sheet 11 is liquid permeable. The back sheet 12 is liquid-impermeable or liquid-impermeable. An adhesive (not shown) or hook-and-loop fastener for fixing the male incontinence pad 10 to the inner surface of the underwear, the diaper or the diaper cover may be applied to the outer surface of the back sheet 12. When this pressure-sensitive adhesive is applied, it is preferable to protect the pressure-sensitive adhesive by covering it with a protective sheet (not shown) subjected to a peeling treatment until the male incontinence pad 10 is used. In addition, when a male material of a hook-and-loop fastener is applied, the male material may be covered and protected by a female material of the hook-and-loop fastener until the male incontinence pad 10 is used.

  As the top sheet 11 and the back sheet 12, the same materials as those conventionally used for this type of absorbent article can be used. For example, as the surface sheet 11, a nonwoven fabric or a perforated film having liquid permeability can be used. As the back sheet 12, a synthetic resin film that is liquid impermeable, a nonwoven fabric that is liquid impermeable, or the like can be used. Or the laminated sheet material of the film made from the synthetic resin which is liquid-impermeable, and a nonwoven fabric can also be used.

  An absorber 13 is disposed between the top sheet 11 and the back sheet 12. The absorber 13 is liquid retaining. The top sheet 11 and the back sheet 12 extend outward from the periphery of the absorber 13, and the extension portions of these sheets are joined to each other so that the absorber 13 is sandwiched between these sheets. . The absorber 13 has the absorptive core 14 which is a main liquid holding part. For the absorbent core 14, for example, a hydrophilic fiber material, for example, a laminate of cellulosic fibers such as fluff pulp, or a mixed laminate of the hydrophilic fiber material and a superabsorbent polymer such as a hydrogel material is used. Can do. The absorbent core 14 may be formed by partially or entirely covering the absorbent core 14 with a core wrap sheet made of a liquid-permeable sheet such as tissue paper. In this embodiment, as shown in FIG.3 and FIG.4, the core wrap sheet | seat 23 is distribute | arranged only to the surface sheet 11 side of the absorptive core 14, and the absorber 13 is formed, and this core wrap sheet | seat 23 is width direction. In Y, it has the same width as the core center region 14C described later, and the overhanging portion 17 is not covered with the core wrap sheet 23.

It is preferable that the absorbent body 13 is thin so as not to cause an uncomfortable feeling when the male incontinence pad 10 is worn. For example, the thickness of the absorber 13 under a pressure of 196 cN / cm ² is preferably 5 mm or less, more preferably 4 mm or less, and even more preferably 3 mm or less. The lower limit value of the thickness is preferably 1.5 mm. When the absorbent core 14 in the absorbent body 13 includes a hydrophilic fiber material and a superabsorbent polymer, the basis weight of the fiber material is preferably 100 g / m ² or more and 240 g / m ² or less, and 120 g / m ^2. and still more preferably m is ² or more 220 g / ^{m 2} or less. On the other hand, the basis weight of the superabsorbent polymer, more preferably it is 40 g / ^{m 2} or more 150 g / ^{m 2} or less is preferable, 40 g / ^{m 2} or more 120 g / ^{m 2} or less.

  The male incontinence pad 10 includes a core material 15. The core material 15 is disposed between the absorber 13 and the back sheet 12. The core material 15 is disposed along the longitudinal direction X at the center position in the width direction Y of the absorber 13. The core material 15 is a member used to give rigidity to the male incontinence pad 10. The core material 15 is comprised from the nonwoven fabric which has air permeability, such as a hydrophilic sheet material, a chemical bond nonwoven fabric, an air through nonwoven fabric, or an airlaid nonwoven fabric, a plastic thin plate, etc., for example. It is preferable that the core material 15 is made of a non-woven fabric having air permeability since the occurrence of stuffiness is effectively suppressed in the wearing state of the male incontinence pad 10. The core material 15 is preferably made of a hydrophilic sheet material in view of easiness of forming wrinkles described later. This sheet material includes a hydrophilic fiber material, for example, a cellulosic fiber such as fluff pulp, and may be a papermaking body manufactured by a wet papermaking method or a dry airlaid method. It is preferable to use a papermaking body as the core material 15 because the absorbed liquid easily diffuses back and forth along the longitudinal direction X.

When the core material 15 is made of the sheet material, the basis weight thereof is preferably 10 g / m ² or more and 80 g / m ² or less, and more preferably 13 g / m ² or more and 60 g / m ² or less. The thickness is preferably 0.2 mm or more and 2 mm or less. The thickness can be measured by using Ozaki Manufacturing Co., Ltd. dial gauge (Peacock model number: No. 207) or the like under 196 cN / cm ² . In this case, an acrylic plate having a length of 36 mm, a width of 36 mm, and a thickness of 3 mm is placed between the sample to be measured and the thickness gauge to perform measurement. The bending stiffness of the sheet material is preferably 5.0 cN or more and 200 cN or less as measured by a handometer (slit width 20 mm, sample size 200 mm × 200 mm). As the handometer, model number P360A manufactured by Daiei Kagaku Seiki Seisakusho can be used.

  The core material 15 is advantageously free of superabsorbent polymer. Because the core material 15 does not contain the superabsorbent polymer, the change in the partial rigidity of the core material 15 is small even when urine is absorbed during product use. The bending of the core material 15 that is not intended can be effectively suppressed, and the fit of the male incontinence pad 10 is improved.

  The sheet material can be used in one sheet or in a multilayer structure in which two or more sheets are overlapped. In the embodiment shown in FIGS. 3 and 4, the core material 15 has a multilayer structure in which a single sheet material is folded in three, and a plurality of sheets are apparently overlapped. Specifically, the sheet material constituting the core material 15 has a first direction that coincides with the longitudinal direction X and a second direction that is orthogonal to the longitudinal direction and coincides with the width direction Y, and a pair of sides along the first direction. It is comprised from the rectangular sheet | seat material which has an area. The core material 15 is configured by folding the sheet material in three along the first direction, that is, the longitudinal direction X so that both side regions overlap. By using such a core material 15, a width extending in the longitudinal direction of the core material 15 when an external force is applied from the outside in the width direction Y to the inside in the wearing state of the male incontinence pad 10. The overhanging portion 17 is easily bent in the width direction Y starting from the direction edge. As a result, the fit of the male incontinence pad 10 is improved.

  The core material 15 and the absorbent body 13 (specifically, the core wrap sheet disposed on the back sheet 12 side of the absorbent core 14 or the absorbent core 14 when no core wrap sheet is present) are joined. Or may be in a non-bonded state. When both are in a non-bonded state, when the male incontinence pad 10 is deformed in the wearing state of the male incontinence pad 10, the core material 15 is longitudinally extended along the width direction Y. A bellows-like wrinkle extending in the direction X is likely to occur, which is preferable. The formation of the ridge is advantageous because it contributes to increasing the rigidity of the core material 15. In particular, it is preferable that the core material 15 is tri-folded so that both side regions overlap each other, since the core material 15 is easily bent into a bellows shape starting from the overlapped portion, so that wrinkles are easily formed. Moreover, the front area A corresponds to the male part, and the rear area B corresponds to the crotch part. Therefore, in the crotch portion, the rear region B hangs down due to gravity, and a gap is easily generated between the wearer and the wearer. On the other hand, the core material 15 forms the above-mentioned ridges to increase the rigidity, so that the rear region B is prevented from sagging, and the gap between the crotch part and the wearer's body is reduced. The fit of the incontinence pad 10 is improved.

  The male incontinence pad 10 includes a pair of leak-proof cuffs 16 extending in the longitudinal direction X at positions on both sides in the width direction Y on the surface sheet 11 side. The leak-proof cuff 16 has a sheet material 16 </ b> A extending in the longitudinal direction X. As shown in FIGS. 3 and 4, the sheet material 16 </ b> A has a side region located on the outer side in the width direction Y among the pair of side regions extending in the longitudinal direction X and is joined to the topsheet 11. . Further, in the sheet material 16A, elastic members 16B are arranged in a stretched state along the side edge at the position of the side edge of the side region located on the inner side in the width direction Y. Thereby, a non-joining part with surface sheet 11 stands up by contraction of elastic member 16B among sheet materials 16A, and liquid resistance leak-proof cuff 16 is formed. The leak-proof cuff 16 extends at least over the region where the absorber 13 is present, and preferably extends over the entire length in the longitudinal direction X of the male incontinence pad 10. Accordingly, the sheet material 16 </ b> A extends over the entire length in the longitudinal direction X of the male incontinence pad 10. In addition, the elastic member 16B is arranged on both sides in the width direction Y of the male incontinence pad 10 in an extended state over at least the region where the absorber 13 exists in the longitudinal direction Y of the male incontinence pad 10. Yes. As the sheet material 16A, for example, a liquid non-permeable nonwoven fabric or the like can be used. The elastic member 16B extends over a length of 50% or more, preferably 80% of the total length in the longitudinal direction X of the male incontinence pad 10, and more preferably absorbs at least the longitudinal direction X of the male incontinence pad 10. It extends over the entire area where the body 13 is present.

  The absorbent core 14 in the absorbent body 13 described above is disposed over substantially the entire length, preferably 80 to 90% of the full length of the male incontinence pad 10, and has an outline in plan view of the absorbent body 13. . And corresponding to the male incontinence pad 10 being divided into the front area A, the central area C and the rear area B, the absorbent core 14 is also composed of the core front area 14A, the core central area 14C and the core rear area 14B. It is divided into. The core front region 14 </ b> A is a region located in the front region A of the male incontinence pad 10 in the absorbent core 14. The core central region 14 </ b> C is a region located in the central region C of the male incontinence pad 10 in the absorbent core 14. Similarly, the core rear region 14 </ b> B is a region located in the rear region B of the male incontinence pad 10 in the absorbent core 14.

  The core front region 14A, the core central region 14C, and the core rear region 14B are continuous with each other and are made of the same material. The thickness and basis weight are generally the same. However, the thickness and / or basis weight of each region may be varied for the purpose of adding an additional function to the male incontinence pad 10. For example, by making the basis weight of the hydrophilic fiber material and the superabsorbent polymer in the core front region 14A and the core center region 14C larger than those basis weights in the core rear region 14B, Absorption speed becomes faster and leakage becomes harder. Moreover, if it is unevenly distributed in the core front area 14A which is a male wearer's excretion part, there will be a further effect. Furthermore, you may form a groove part and a through-hole in at least 1 of each area | region. In particular, forming a groove and / or a through-hole in the core central region 14C is advantageous in that it increases the diffusibility of urine and improves the absorption capacity, thereby preventing leakage. On the other hand, in the core front region 14A, it is preferable not to form a groove and / or a through hole. This is because the core front region 14A is a region facing the excretion portion of the wearer, and therefore does not cause leakage even when urine is excreted vigorously. One or more grooves and / or through-holes can be formed so as to extend along the longitudinal direction X, for example.

  As shown in FIG. 2B, the core central region 14 </ b> C has the minimum width WC of the absorbent core 14 among the core front region 14 </ b> A, the core central region 14 </ b> C, and the core rear region 14 </ b> B constituting the absorbent core 14. The core front region 14A has the maximum width WA of the absorbent core 14. Furthermore, the core rear region 14B has an intermediate width WB that is an intermediate width between the minimum width WC and the maximum width WA. That is, WC <WB <WA. Therefore, when comparing the core front region 14A and the core central region 14C, the width in the core front region 14A is wider than the width in the core central region 14C. , A pair of projecting portions 17, 17 projecting outward in the width direction Y from the side edge in the core central region 14C. Paying attention to the core front region 14A, the core front region 14A includes a central portion 18 located at the center in the width direction Y and the above-described overhang portions 17 and 17 extending outward from the central portion 18 in the width direction. And. As another form, WB and WC may have the same width, that is, WC = WB <WA.

The core material 15 which is a member located on the lower surface side of the absorbent body 13 has a length in the longitudinal direction X substantially equal to or shorter than the length in the longitudinal direction of the absorbent core 14. . When the length of the core material 15 is shorter than the length of the absorbent core 14, the length of the core material 15 is preferably 50% or more, more preferably 60% of the length of the absorbent core 14. Or more, preferably 100% or less, more preferably 95% or less. Regarding the length in the width direction Y, the length of the core material 15 in the width direction Y substantially matches the minimum width WC in the core central region 14C of the absorbent core 14 as shown in FIG. Therefore, in the core front region 14A of the absorbent core 14 that is the portion having the maximum width WA, the core material 15 is located immediately below the central portion 18 of the core front region 14A. And the core material 15 does not exist in the area | region of the absorber 13 corresponding to the overhang | projection part 17 of 14 A of core front areas. Therefore, the front elastic member 20 and the core material 15 do not overlap. In other words, in the core front region, the absorbent body 13 has a central portion 18 having the absorbent core 14 and the core material 15, and extends outward from the central portion 18 in the width direction Y, and the absorbent core 14. And a pair of overhang portions 17 that do not have the core material 15. Even if the thickness of the hydrophilic fiber material that constitutes the absorbent core 14 is uniform in the width direction, the overhanging portion is compared with the central portion 18 because the core front region A has such a configuration. 17 has a small number of constituent members. As a result, the overhanging portion 17 has a bending rigidity lower than that of the central portion 18. The magnitude of the bending stiffness can be judged by comparing the measurement results using a handometer, for example. In this case, the handometer is a handometer made by Daiei Kagaku Seiki Seisakusho (model number: P360A), and the measurement conditions are a sample with a measuring instrument slit width of 30 mm and a length of 15 cm cut from the core front area A in the longitudinal direction. To measure. However, when the size of the male incontinence pad 10 is small and a sample of 15 cm or more cannot be taken, the length can be changed for measurement. The center portion 18 in the width direction Y (the portion including the core material 15 and the absorber 13) and the boundary between the core material in the longitudinal direction X and the overhang portion 17 are placed in parallel to the center portion of the slit width of the measuring instrument, and measurement is performed. be able to. If the slit width of the measuring instrument is too wide for the sample for evaluation, the slit width of the measuring instrument may be narrowed for evaluation. However, in order to measure and compare the bending stiffness of the overhang portion 17 and the bending stiffness of the central portion 18, the sample size and the slit width of the handometer are assumed to be the same. The thickness of the absorbent core 14 can be measured using, for example, Ozaki Manufacturing Co., Ltd. dial gauge (Peacock model number: No. 207). First, the adhesive is removed from the male incontinence pad 10 using an organic solvent, and materials other than the absorbent core 14 are carefully peeled off. Next, the removed absorbent core 14 is measured by applying a load of 36.6 mg / cm ² . At this time, in the core front region 14A, the thickness at any five points from the central portion 18 to the overhang portion 17 is measured to obtain an average value, and the thickness at each measurement point is 1.8 times or more of the average value. If it is 2 times or less, it is judged that the thickness is uniform. The load of 36.6 mg / cm ² is substantially no load, but if measured without any load, the measured value will be blurred because the pulp contained in the absorbent core 14 is fluffy. . Therefore, in order to suppress measurement fluctuation, measurement is performed with a slight load.

In the male incontinence pad 10, another sheet 19 may be disposed between the top sheet 11 and the absorber 13. Hereinafter, the sheet 19 is referred to as a “sublayer sheet 19”. The sublayer sheet 19 is used to give an additional function to the male incontinence pad 10. Examples of additional functions include a deodorizing function for odors generated from absorbed urine and a function for preventing reversion of absorbed urine. In order to impart a deodorizing function, the sublayer sheet 19 may contain a deodorant such as activated carbon. In order to provide the function of preventing the return of urine, for example, a fiber sheet having a low fiber presence density and a bulky structure may be used as the sublayer sheet 19 so that the top sheet 11 and the absorber 13 are separated from each other. As the sublayer sheet 19, for example, an air-through nonwoven fabric, a spunbond nonwoven fabric, a three-dimensionally shaped nonwoven fabric, or an apertured film can be used as a hydrophilic sheet material. Moreover, it is preferable that the basic weight of the sublayer sheet 19 is 20 g / m ² or more and 60 g / m ² or less.

  The sublayer sheet 19 can be disposed over the entire area of the absorbent body 13 facing the surface sheet 11, or can be disposed only on a part of the opposed surface. When the sub-layer sheet 19 is disposed only on a part of the opposing surface, for example, as shown in FIGS. can do. In this case, it is preferable to dispose the sublayer sheet 19 in at least the central region C, more preferably to dispose the sublayer sheet 19 in the central region C and the front region A, and the sublayer sheet over the entire longitudinal direction in the absorber 13. More preferably, 19 is disposed.

  In the male incontinence pad 10, as shown in FIGS. 3 and 5, a thread shape extending in the longitudinal direction X at the position of each overhanging portion 17 of the core front region 14 </ b> A in the absorbent core 14 of the absorbent body 13 described above. The elastic members 20 are arranged in an extended state. Hereinafter, the elastic member 20 is referred to as a “front elastic member 20” for the purpose of distinguishing it from other elastic members. The front elastic member 20 is located closer to the back sheet 12 than the top sheet 11. Specifically, in the present embodiment, the front elastic member 20 is disposed at a position directly below the absorbent core 14 in the absorbent body 13 and between the absorbent core 14 and the back sheet 12. . By disposing the front elastic member 20 at the position of the overhanging portion 17, each overhanging portion 17 of the core front region 14 </ b> A stands up toward the wearer's body due to contraction of the front elastic member 20 to form a weir. To do. Thereby, the front area A of the male incontinence pad 10 is deformed into a cup shape, and the fit is improved. When the male incontinence pad 10 does not have the leak-proof cuff 16, the surface of the dam portion on the body side of the wearer is covered with the top sheet 11. Therefore, the weir part is liquid-absorbing, and side leakage of urine is effectively prevented. Moreover, since the overhanging portion 17 is composed of the absorbent core 14, the excreted urine reaches the overhanging overhanging portion 17 and is immediately absorbed by the overhanging portion 17 when it is dammed up. Therefore, even when a large amount of urine is excreted at once, the disadvantage of the prior art that the absorption rate cannot catch up with the rate of urination due to absorption of urine by both the central portion 18 and the overhanging portion 17 is solved. . Note that “the elastic member 20 is disposed at the position of the overhanging portion 17” means that the elastic member 20 is disposed at an outer position in the width direction Y from the boundary between the overhanging portion 17 and the central portion 18. This is intended to include not only the case but also the case where the elastic member 20 is arranged at the position of the boundary.

  In particular, by disposing the front elastic member 20 closer to the back sheet 12 than the top sheet 11, the contraction force of the front elastic member 20 is easily transmitted to the absorbent core 14 and has a shape covering the male genitals. The liquid receiving area can be secured. From the viewpoint of preventing the front elastic member 20 from inhibiting liquid absorption, the front elastic member 20 is formed between the absorbent core 14 and the back sheet 12 rather than between the top sheet 11 and the absorbent core 14. It is preferable to arrange | position in the position of between. By disposing the front elastic member 20 at a position between the absorbent core 14 and the back sheet 12, the overhanging portion 17 contracts due to the contraction of the front elastic member 20, and the contraction force of the elastic member 16B. The surface sheet 11 that is the liquid receiving surface can easily form a concave shape (so-called cup shape) by this synthesis, thereby covering the excretory part, improving the fit at the time of wearing, and preventing displacement and liquid leakage. I can do it.

  When the male incontinence pad 10 has the leak-proof cuff 16, when the male incontinence pad 10 is extended flat and viewed in plan, the front elastic member 20 is the elastic member of the leak-proof cuff 16 described above. It is preferable to be located outward in the width direction Y rather than 16B. By adopting such an arrangement relationship, the core front region 14A is more easily deformed into a cup shape by the synergistic effect of the contraction stress of the front elastic member 20 and the contraction stress of the elastic member 16B of the leak-proof cuff 16. . Even when the front elastic member 20 has a weak contraction stress, the overhanging portion 17 is easily deformed with the assistance of the contraction stress of the elastic member 16B of the leak-proof cuff 16, and the core front region 14A is deformed into a cup shape. It becomes easy to do. As a result, two leak-proof gathers are formed by the weir portion and the leak-proof cuff 16 formed by the overhanging portion 17 erected by the elastic member 16B. Therefore, even when a large amount of urine is excreted at one time and the urine cannot be blocked by the leak-proof cuff 16, the urine is blocked by the overhanging portion 17, and from the portion sandwiched between the pair of leak-proof cuffs 16 and 16. Urine flows to the central portion 18 and immediately flows from the central portion 18 to the overhang portion 17 and is absorbed.

  Further, the projecting portion 17 is formed with one or more streak-like embossed portions extending along the longitudinal direction X, or a streak-like embossed portion extending obliquely so as to intersect the longitudinal direction X. The core front region 14A can be easily deformed into a cup shape by forming it in one or multiple lines.

  Furthermore, as described above, the core front region 14A is composed of the central portion 18 and the overhanging portion 17 extending outward in the width direction Y from the central portion 18, and the bending rigidity of the overhanging portion 17 is By making it lower than the bending rigidity of the central portion 18, the core front region 14A itself is easily deformed at or near the boundary between the overhanging portion 17 and the central portion 18. It becomes easy to deform into a cup shape. From the viewpoint of making this effect even more prominent, it is advantageous to increase the rigidity of the core material 15 disposed at a position overlapping the central portion 18 of the absorbent core 14 in the thickness direction. From this point of view, as shown in FIGS. 6A to 6C, the core material 15 formed by folding the sheet material in three is folded in three and the regions facing each other are bonded by an adhesive 21. It is preferable.

  The elastic member 16B disposed on the front elastic member 20 and the leak-proof cuff 16 described above can be made of, for example, thread rubber, flat rubber, or film-like rubber. When these elastic members are made of thread rubber, the fineness of the thread rubber is preferably 400 dtex or more and 1000 dtex or less, and more preferably 500 dtex or more and 950 dtex or less. Further, the fineness of the rubber thread used as the elastic member 16 </ b> B disposed in the leak-proof cuff 16 is preferably 1.2 to 2.0 times the fineness of the rubber thread used as the front elastic member 20.

  The elastic member 16B disposed on the front elastic member 20 and the leak-proof cuff 16 is preferably disposed at an expansion ratio of 1.4 to 2.2 times, particularly 1.5 to 2.0 times. . Adopting an expansion ratio in this range produces a sufficient contractile force. In addition, the residual strain when these elastic members expand and contract is prevented from becoming excessively large, and a gap is formed between the male incontinence pad 10 and the wearer's body when the male incontinence pad 10 is worn. It becomes difficult to occur.

  In the form shown in FIG. 6A, the adhesive 21 is applied in a wide spiral shape or stripe shape over the entire region in the width direction Y. The spiral adhesive 21 extends in the longitudinal direction, which is a direction orthogonal to the paper surface. In the form shown in FIG. 6B, a plurality of adhesives 21 are applied at intervals in the width direction Y. Each strip of adhesive 21 is applied in a narrow spiral shape and extends in the longitudinal direction, which is a direction perpendicular to the paper surface. In the form shown in FIG. 6C, the adhesive is applied to almost the entire width between the regions that are folded in three and face each other. The rigidity of the core material 15 can be adjusted by the application pattern of the adhesive 21 as shown in FIGS. Instead of or in addition to this, the amount of adhesive 21 can be adjusted.

  The core material 15 in the form shown in FIG. 6 (d) is different from the core material described so far, and when the sheet material constituting the core material 15 is folded in three, both side areas are not overlapped. The edge is in a state of being abutted. In FIG. 6 (d), the adhesive is not shown between the three folded regions facing each other, but the adhesive is applied in the patterns shown in FIGS. 6 (a) to 6 (c) or other patterns. May be.

  As shown in FIGS. 6 (a) to 6 (c), the sheet material is folded in three so that both side regions overlap, and as shown in FIG. 6 (d), both side edges are overlapped without overlapping both side regions. In any form in which the sheet material is folded in three so as to be in an abutted state, the core material 15 so that the overlapped part or the abutted part faces the absorbent core 14 May be arranged.

  As described above, in the male incontinence pad 10, the overhanging portion 17 that is a liquid-absorbing standing weir is formed by increasing the width of the core front region 14 </ b> A of the absorbent core 14. However, if the width of the absorbent core 14 is increased to simply increase the absorption capacity, the feeling of fitting and fit of the male incontinence pad 10 will be diminished. Therefore, in the present invention, by reducing the width of the core central region C of the absorbent core 14 to be smaller than the width of the core front region 14A, without reducing the wearing feeling and fit of the male incontinence pad 10, The urine absorption performance and side leakage prevention performance in the core front region 14A are enhanced.

  On the other hand, the width of the core rear region 14B is desirably widened from the viewpoint of enhancing the absorption performance in the core rear region 14B. However, the core rear region 14B has a lower urine output than the core front region 14A, and the width of the core rear region 14B is reduced in order not to reduce the fit and fit of the male incontinence pad 10. There is no need to make it as large as the width of 14A. Therefore, the width of the core rear region 14B is the same as the width of the core central region 14C, or larger than the width of the core central region 14C, but preferably smaller than the width of the core front region 14A. Since the width of the core rear region 14B is smaller than the width of the core front region 14A, it is possible to prevent a sense of incongruity during mounting. In addition, since the male incontinence pad 10 is worn with a bias toward the wearer's front, the pad hangs down due to gravity and is likely to be displaced. However, since the core rear region 14B is located at the crotch part of the wearer, if the width of the core rear region 14B is wider than the width of the core central region 14C, the width direction Y received from the wearer's legs Due to the pressure toward the inner side, it becomes easy to bend along the vertical direction starting from the side edge of the core material 15. Thereby, the contact area between the pad and the wearer is increased, and deviation is prevented. Furthermore, the absorbability of the core rear region 14B is improved, and leakage due to the liquid flowing along the longitudinal direction X can be prevented.

  From the viewpoint of further ensuring that the front area A of the male incontinence pad 10 is deformed into a cup shape, the front elastic member 20 is disposed over the entire region in the longitudinal direction X of the overhang portion 17 or substantially the entire region. preferable. In this case, the length in which the front elastic member 20 is disposed may be the same as the length of the overhanging portion 17 in the longitudinal direction X, or may be longer on the core central region 14C side. When the front elastic member 20 extends outward in the longitudinal direction X from the overhanging portion 17, wrinkles occur in the end flap (portion where the absorbent core 14 does not exist) on the front region A side, and the appearance and appearance look great. From the viewpoint of avoiding deterioration, the length of the extended portion of the front elastic member 20 beyond the overhang portion 17 is preferably 0 mm or more and 20 mm or less, although it depends on the size of the male incontinence pad 10.

  When the length in which the front elastic member 20 is arranged is the same as the length of the overhanging portion 17 in the longitudinal direction X, the contraction stress of the front elastic member 20 acts only on the overhanging portion 17 and acts on other portions. As a result, unnecessary contraction sites do not occur. As a result, an unintended decrease in the liquid receiving surface due to contraction can be effectively prevented. This effect is that the front elastic member 20 is arranged only at the position of the overhanging portion 17 even when the length in which the front elastic member 20 is arranged is shorter than the length of the overhanging portion 17 in the longitudinal direction X. If played, it will be played. In that case, from the viewpoint of reliably expressing the effect, the length in which the front elastic member 20 is disposed is preferably 80% or more of the length in the longitudinal direction X of the overhang portion 17 and is 90% or more. More preferably it is. Moreover, it is preferable that it is 100% or less from a viewpoint of preventing the reduction | decrease of the liquid receiving surface by shrinkage | contraction.

  On the other hand, when the length in which the front elastic member 20 is arranged is longer than the length of the overhanging portion 17 in the longitudinal direction X, an overhanging portion in which the front elastic member 20 protrudes from the overhanging portion 17 occurs. This protruding portion can exist either before or after the overhanging portion 17 in the longitudinal direction X, or can exist both before and after. In the case where the protruding portion occurs, the front elastic member 20 extends beyond the end on the central region C side of the overhanging portion 17 and reaches the core rear region 14B. Since the top sheet 11 side is inwardly deformed into a cup shape, the male incontinence pad 10 can be further fitted to the wearer's body even in the region from the central region C to the rear region B. When the elastic member 20 extends beyond the end of the central region C but does not reach the core rear region 14B, a cup shape is formed only in the core front region 14A and the core central region 14C to fit the wearer. In the core rear region 14B, there is no contraction along the longitudinal direction X of the male incontinence pad 10, and the uncomfortable feeling during wearing can be reduced.

  The front elastic member 20 is joined to a member sandwiching the front elastic member 20 at at least two positions separated along the extending direction. For example, when the length in which the front elastic member 20 is arranged is the same as the length in the longitudinal direction X of the overhanging portion 17, the front elastic member 20 is disposed at the both end portions thereof at the absorbent core 14 and the back surface. The sheet 12 can be fixed. On the other hand, when the length in which the front elastic member 20 is disposed is longer than the length in the longitudinal direction X of the overhanging portion 17, in addition to fixing the front elastic member 20 at the position of the overhanging portion 17, or Instead, the protruding portion that protrudes from the front and back in the longitudinal direction X of the overhang portion 17 can be fixed by being sandwiched between the top sheet 11 and the back sheet 12.

  In particular, when the members sandwiching the front elastic member 20 are joined via the front elastic member 20 over the entire length of the front elastic member 20, the contraction stress of the front elastic member 20 is effectively transmitted to the member. This is preferable because the above-described cup shape is more reliably formed. For example, when the front elastic member 20 is arranged as shown in FIG. 3, it is preferable that the absorbent core 14 and the back sheet 12 are joined via the front elastic member 20.

  In the above-described embodiment shown in FIG. 5, one front elastic member 20 is arranged on one overhanging portion 17. However, as another embodiment, as shown in FIG. Two or more front elastic members may be arranged. By adopting such an arrangement, the uprightness of the overhanging portion 17 can be further improved, and the core front region 14A is more reliably deformed into a cup shape.

  When the embodiment shown in FIG. 7 is adopted, it is preferable that the front elastic members 20 are separated from each other along the width direction Y from the viewpoint that the contraction stress can be effectively applied. For the same reason, when attention is paid to any two front elastic members 20, the front elastic member 20 located on the outer side in the width direction Y is more than the front elastic member 20 located on the inner side. It is preferable that the tensile stress is large. The extension stress of the front elastic member 20 can be adjusted by, for example, the thickness of the front elastic member 20, the degree of stretching, the material, and the like.

  FIG. 8 shows yet another embodiment. This figure corresponds to FIG. 3 described above, and shows a cross section in the width direction Y of the front area A of the male incontinence pad 10. This embodiment is different from the embodiment shown in FIG. 3 in that the absorber 13 does not include a core material. For the other points, the description of the embodiment described so far applies similarly. Also in the embodiment shown in FIG. 8, the core front region 14 </ b> A is deformed into a cup shape, and urine side leakage is effectively prevented.

  The male incontinence pad 10 as described above is particularly suitable as a male incontinence pad for urine absorption that is attached to the inner surface of an undergarment or attached to the inner surface of a diaper or a diaper cover.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this embodiment is not restrict | limited to the said embodiment. For example, although the front elastic member 20 is disposed at a position between the absorbent core 14 and the back sheet 12 in the embodiment, the front elastic member 20 is positioned on the back sheet 12 side with respect to the top sheet 11. For example, it may be arranged at a position between the topsheet 11 and the absorbent core 14.

  In the embodiment, a thread-like elastic member is used as the front elastic member 20, but a film-like elastic member having a width and a length may be used instead.
