Description

[Technical Field]

[0001] The present disclosure relates to an absorbent article for men that is excellent at preventing displacement of the male genitalia. [Background technology]

[0002] Absorbent articles are commercially available for mild incontinence and moderate to severe incontinence. These products are appropriately selected according to the wearer's condition and are used at home, in nursing homes, hospitals, etc.

[0003] However, in nursing care settings for elderly men, urinary incontinence, a problem unique to men, is becoming a problem. For example, because the male genitalia of elderly men shrink with age, when outerwear such as pants or tape is worn directly on the body, a gap may form between the outerwear and the body. In this case, the male genitalia may protrude from the gap between the outerwear and the body, and the outerwear may not be able to absorb urine discharged from the male genitalia. Alternatively, urine discharged from the male genitalia, which is held inside the outerwear, may leak out of the outerwear through the gap between the outerwear and the body.

[0004] To solve this problem, a common approach is to use an inner layer inside the outer layer. For example, Patent Document 1 discloses a method in which the genitals (male genitalia) are wrapped in an inner pad, such as a urine absorption pad, inside the outer layer.

[0005] However, because the inner pad is thick, this thickness creates a gap between the inner pad and the outer disposable diaper, causing the problem of urine leaking out through the gap. As a solution to this problem, an additional inner pad is sometimes added to fill the gap, but this is not efficient as it consumes more padding than necessary.

[0006] Meanwhile, another solution to these urinary leakage problems has been disclosed, which uses a tubular product. For example, Patent Document 2 discloses a disposable diaper for men in which the absorbent main body is folded in half lengthwise, with the longitudinal center as the folding part, and the abutting side flaps are fixed together to form a bag-like shape. This allows the diaper to be assembled correctly when put on, and also reduces the risk of urinary leakage.

[0007] However, Patent Document 2 had the problem that the male genitalia was prone to slipping on the flat absorbent body inside the tube, causing it to easily shift. This instability in maintaining its position led to the male genitalia shifting out of the tube, resulting in urinary leakage when worn.

[0008] As described above, cylindrical absorbent articles for men have the problem of urine leakage due to misalignment of the male genitalia, and there has been a need to solve this problem. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 11-019109 [Patent Document 2] Japanese Patent Application Publication No. 09-019452 Summary of the Invention [Problem to be solved by the invention]

[0010] Therefore, an object of the present invention is to provide a male absorbent article that can prevent the male genitalia from shifting relative to the absorbent main body when worn. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, embodiments of the present invention (hereinafter referred to as "embodiments") will be described in detail with reference to the accompanying drawings. These embodiments are provided for illustrative purposes and are not intended to limit the present invention. Note that the same elements are designated by the same reference numerals throughout the description of the embodiments.

[0019] In this specification, the following definitions are used. The up-down direction refers to the direction in which the head side of the wearer of the male absorbent article 10 (hereinafter simply referred to as the "wearer") is upward and the feet side is downward. The front-rear direction refers to the direction in which the wearer's ventral side is forward and the back side is backward. The state in which the male absorbent article 10 is worn refers to the state in which the wearer puts the male absorbent article 10 on his male genitalia 1, regardless of whether urine is absorbed before, during, or after absorption. The longitudinal direction of the male absorbent article 10 refers to the direction along the insertion direction of the wearer's male genitalia 1 when the male absorbent article 10 is worn (the direction along arrow X in the figure). The width direction of the male absorbent article 10 refers to the lateral direction (the direction along arrow Y in the figure) that is perpendicular to the longitudinal direction of the male absorbent article 10 in its unfolded state. The thickness direction of the male absorbent article 10 refers to the direction approximately perpendicular to the plane containing the longitudinal and width directions (the direction along arrow Z in the figure). Furthermore, the skin side refers to the direction of the insertion space 13 into which the male genitalia 1 is inserted in the thickness direction of the male absorbent article 10 (the direction along the arrow Z in the figure), and the non-skin side refers to the direction opposite the skin side in the thickness direction of the male absorbent article 10.

[0020] FIG. 1 is a diagram schematically illustrating the appearance of a men's absorbent article 10 according to a first embodiment of the present invention. FIG. 2 is an explanatory diagram illustrating the men's absorbent article 10 being worn by a wearer. FIG. 3 is a plan view of the men's absorbent article in an unfolded state. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3. FIG. 5 is a cross-sectional view taken along line VV in FIG. 3. Note that FIG. 2 illustrates the men's absorbent article 10 being worn as an inner layer, with an outer layer 2 such as underwear or a disposable diaper worn over it.

[0021] As shown in Figures 1 and 2, a male absorbent article 10 according to this embodiment is formed in a bag shape extending in the longitudinal direction. An opening 11 is provided on one longitudinal side (the upper side in Figure 1) of the male absorbent article 10. The male absorbent article 10 defines an insertion space 13 on its interior that extends from the opening 11 to a bottom 12 on the other longitudinal side (the lower side in Figure 1). The male absorbent article 10 is worn by inserting the male genitalia 1 into the insertion space 13 through the opening 11 (see Figure 2). In the following description, it is assumed that the male absorbent article 10 is worn in a state in which the opening 11 of the male absorbent article 10 is located on the upper side, the male absorbent article 10 extends in the longitudinal direction from the front of the wearer toward the crotch area, and the width direction of the male absorbent article 10 is aligned with the left-right direction of the wearer, as shown in Figure 2.

[0022] 1 to 5, the men's absorbent article 10 includes an exterior body 20 that forms the bag-shaped outer shape of the men's absorbent article 10, and an absorbent main body 30 that is attached to the inner surface (skin side) of the exterior body 20. As will be described later, the men's absorbent article 10 is formed into a bag shape by folding the sheet-like exterior body 20 and absorbent main body 30 in an unfolded state.

[0023] As shown in Figures 3 to 5, the exterior body 20 is a component that constitutes the outer shape of the men's absorbent article 10, and is formed by laminating nonwoven fabrics and stretchable members. In this embodiment, the exterior body 20 is formed by laminating an outer nonwoven fabric sheet 21 that faces away from the skin, an inner nonwoven fabric sheet 22 that faces the skin of the outer nonwoven fabric sheet 21, and a plurality of elastic members 23 that are interposed between the outer nonwoven fabric sheet 21 and the inner nonwoven fabric sheet 22. In addition to the outer nonwoven fabric sheet 21 and the inner nonwoven fabric sheet 22, an auxiliary sheet that covers the periphery of the absorbent main body 30 may be provided in the exterior body 20, and the auxiliary sheet may be laminated on the inner nonwoven fabric sheet 22.

[0024] The outer nonwoven fabric sheet 21 and the inner nonwoven fabric sheet 22 can be made of a nonwoven fabric such as a thermal bonded nonwoven fabric, an air-through nonwoven fabric, or a spunbonded nonwoven fabric, preferably an air-through nonwoven fabric or a spunbonded nonwoven fabric made of a thermoplastic resin such as polypropylene, polyester, or polyethylene. When such a nonwoven fabric is used, its basis weight is 10 g / m 2 More than 40g / m 2 The following would suffice.

[0025] As shown in Fig. 3, the exterior body 20 in an unfolded state before being formed into a bag shape is formed into a sheet shape extending in the longitudinal direction. An absorbent main body 30, which will be described later, is fixed to the skin-facing surface of the exterior body 20 in an unfolded state (the surface on the near side in Fig. 3). Multiple elastic members 23 (six in total, three on each side in Fig. 3) are stretchable elastic members that are arranged at both longitudinal ends of the exterior body 20 in an unfolded state and extend in the width direction. Side flaps 14 that extend along the length are provided at both widthwise ends of the exterior body 20 in an unfolded state. The exterior body 20 in an unfolded state is folded in half along a longitudinal center line CL so that the absorbent main body 30 is on the inside, and the side flaps 14 on both opposing widthwise sides are fixed to each other, thereby forming the exterior body 20 into a bag shape. Region 20a on one side of center line CL in the longitudinal direction of outer body 20 in the unfolded state and region 20b on the other side face each other in a direction intersecting the longitudinal direction (front-to-back direction when worn) when outer body 20 in the unfolded state is folded in half along center line CL. Both longitudinal edge portions of outer body 20 in the unfolded state function as opening 11 of men's absorbent article 10 when outer body 20 is formed into a bag shape. That is, the end portion of opening 11 of men's absorbent article 10 is stretchable in the circumferential direction by elastic member 23. Furthermore, the central portion of outer body 20 in the unfolded state, including center line CL in the longitudinal direction, functions as bottom portion 12 of men's absorbent article 10 when outer body 20 is formed into a bag shape. In the following description, of regions 20a and 20b of outer body 20, the one located on the front side when worn will be referred to as front outer body 20a, and the one located on the rear side will be referred to as rear outer body 20b.

[0026] The absorbent main body 30 is a member for absorbing urine, formed in the shape of a sheet extending in the longitudinal direction, and laminated and fixed to the skin-facing surface of the inner nonwoven fabric sheet 22 of the exterior body 20. In the present embodiment, the absorbent main body 30 is laminated and fixed to the skin-facing surfaces of the inner nonwoven fabric sheets 22 of both the front exterior body 20a and the rear exterior body 20b, and is folded together with the exterior body 20 when the unfolded exterior body 20 is folded in half along the center line CL. The absorbent main body 30 integrally has a front region 30a that is fixed to the front exterior body 20a and located in front of the insertion space 13 when the garment is worn, and a rear region 30b that is fixed to the rear exterior body 20b and located in the rear of the insertion space 13 when the garment is worn. That is, the absorbent main body 30 is arranged on at least one side (both sides in the present embodiment) of the insertion space 13 in a direction intersecting the longitudinal direction (in the present embodiment, the front-to-rear direction when the garment is worn). Each of the front region 30a and the rear region 30b of the absorbent main body 30 extends in the longitudinal direction from the bottom 12 of the men's absorbent article 10 to the end on the opening 11 side (in this embodiment, near both longitudinal ends where the elastic members 23 of the exterior body 20 in the unfolded state are provided). Note that in this embodiment, an absorbent main body 30 having the front region 30a and the rear region 30b integrally therewith is provided, but this is not limited thereto, and two separate absorbent main bodies 30, a front region and a rear region, may also be provided.

[0027] The absorbent body 30 has a liquid-permeable top sheet 31 placed on the skin side, a liquid-impermeable back sheet 32 ​​placed on the non-skin side, and an absorbent body 33 placed between the top sheet 31 and the back sheet 32.

[0028] The top sheet 31 may be formed from a liquid-permeable substrate that allows urine to move toward the absorbent body 33. Examples of substrates include nonwoven fabrics such as air-through nonwoven fabrics, thermal-bonded nonwoven fabrics, and spun-bonded nonwoven fabrics; composite nonwoven fabrics that are thermal-bonded nonwoven fabric / spun-bonded nonwoven fabric laminates; foamed films such as urethane foam; and composite sheets that are laminates of two or more of these. Furthermore, the top sheet 31 may be embossed or perforated on its surface to improve liquid permeability. Such embossing or perforation may be achieved by any known method without limitation. Furthermore, the top sheet 31 may contain lotions, antioxidants, anti-inflammatory ingredients, pH adjusters, antibacterial agents, moisturizers, and the like to reduce irritation to the skin.

[0029] The basis weight of the top sheet 31 is set to 18 g / m from the viewpoints of strength, processability, and liquid return. 2 More than 40g / m 2 It is preferable that the thickness is 18 g / m or less. 2 If it is smaller than this, the top sheet 31 tends to be easily damaged during the production of the absorbent body 30. 2 If it is larger, the top sheet 31 tends to feel hard when it touches the skin, which is undesirable in either case. The shape of the top sheet 31 is not particularly limited, but it may be in a shape that covers the absorbent body 33 so as to guide urine to the absorbent body 33 without leaking.

[0030] As shown in FIGS. 3 to 5, the top sheet 31 has top sheet recesses 31a extending in the longitudinal direction while being recessed from the skin side to the non-skin side. The top sheet recesses 31a are formed, for example, by embossing, and are arranged to align with and overlap the positions of absorber recesses (recesses) 34 (described later) of the absorber 33. In this embodiment, the top sheet recesses 31a are arranged in the center in the width direction of the top sheet 31. The top sheet recesses 31a extend continuously between the front region 30a and the rear region 30b of the absorbent main body 30 via the bottom 12. In other words, the other longitudinal sides of the top sheet recesses 31a in both the front region 30a and the rear region 30b of the absorbent main body 30 extend to the bottom 12 of the male absorbent article 10 and are continuous with each other at the bottom 12. The one longitudinal side of the top sheet recesses 31a in both the front region 30a and the rear region 30b of the absorbent main body 30 is located closer to the bottom 12 (the other longitudinal side) than the ends 35 on the opening 11 side of the front region 30a and the rear region 30b of the absorbent main body 30. In this embodiment, the top sheet recesses 31a are provided in the top sheet 31, but the top sheet recesses 31a do not have to be provided.

[0031] The backsheet 32 ​​may be formed using a liquid-impermeable substrate to prevent leakage of urine held in the absorber 33 to the non-skin side, and may be formed from a material such as a resin film or a composite sheet formed by laminating a resin film and a nonwoven fabric. The nonwoven fabric used in the composite sheet may be made by any method, and examples thereof include various nonwoven fabrics such as air-through nonwoven fabrics, spunbond nonwoven fabrics, and meltblown nonwoven fabrics, composite nonwoven fabrics such as laminates of spunbond nonwoven fabrics / meltblown nonwoven fabrics and spunbond nonwoven fabrics / meltblown nonwoven fabrics / spunbond nonwoven fabrics, and composite materials thereof. Examples of resin films include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0032] The basis weight of the back sheet 32 ​​is set to 15 g / m from the viewpoint of strength and processability. 2 More than 60g / m 2It is preferable that the back sheet 32 ​​has a thickness of 1 / 4 mm or less. In addition, in order to prevent stuffiness during wear, it is preferable that the back sheet 32 ​​has breathability. To make the back sheet 32 ​​breathable, for example, a filler may be blended into the resin film of the base material or the back sheet 32 ​​may be embossed. Note that calcium carbonate can be used as the filler, and the blending method can be any known method without limitation. For example, a porous (breathable) resin film can be obtained by kneading a resin and a filler, forming the resulting kneaded product into a film, and removing the filler from the resulting film.

[0033] The absorbent body 33 contains absorbent fibers as a base material and a superabsorbent polymer. The absorbent fibers of the absorbent body 33 are not particularly limited as long as they are generally used in absorbent articles such as sanitary napkins, disposable diapers, and urine absorption pads, and examples thereof include fluff pulp and cellulose acetate tow. The superabsorbent polymer of the absorbent body 33 is not particularly limited as long as it can absorb body fluids and prevent backflow, and examples thereof include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponified products thereof. Among these, polyacrylates are preferred from the viewpoint of absorption capacity per weight, and sodium polyacrylate is more preferred.

[0034] In addition, when fluff pulp or cellulose acetate tow is used as the base material, the basis weight of the supported superabsorbent polymer is 100 g / m 2 More than 600g / m 2 Preferably, it is 245 g / m or less. 2 More than 445g / m 2 By keeping the value within the above range, gel blocking in the absorbent body 33 can be prevented and the absorbent body 33 can absorb a large amount of body fluid.

[0035] The cellulose acetate tow is preferably opened, and the basis weight of the opened cellulose acetate tow is 20 g / m 2 More than 120g / m 2 Preferably, it is 45 g / m or less. 2 More than 85g / m 2 By keeping the value within the above range, there is no problem in forming the absorbent body 33, and there is no problem in the bodily fluid retention performance of the highly absorbent polymer.

[0036] The absorber 33 has an absorber recess (recess) 34 extending in the longitudinal direction while recessed from the skin side to the non-skin side. The absorber recess 34 is located in the center of the absorber 33 in the width direction. In this embodiment, the absorber recess 34 is formed as a groove with a bottom and a U-shaped cross section recessed from the skin side to the non-skin side, extending in the longitudinal direction. In addition, in this embodiment, the non-skin side surface of the absorber 33 is formed in a substantially flat shape. That is, in this embodiment, the thickness of the absorber recess 34 of the absorber 33 is thinner than the thickness of other regions of the absorber 33. The absorber recess 34 extends continuously between the front region 30a and the rear region 30b of the absorbent main body 30 via the bottom 12. That is, the other longitudinal sides of the absorber recesses 34 in both the front region 30a and the rear region 30b of the absorbent main body 30 extend to the bottom 12 of the men's absorbent article 10 and are continuous with each other at the bottom 12. The longitudinal ends 36 of the absorber recesses 34 in both the front region 30a and the rear region 30b of the absorber 30 are located closer to the bottom 12 (the other longitudinal side) than the opening 11-side ends 35 of the front region 30a and the rear region 30b of the absorber 30. That is, the absorber recesses 34 extend from a position spaced from the opening 11 toward the other longitudinal side of the absorber 30 to the bottom 12. An area 37 in the absorber 33 where no recesses are provided is present on the longitudinal side of the absorber recesses 34. The depth (thickness direction) L1 of the absorber recesses 34 is preferably set to a depth equal to or greater than half the thickness L2 of the absorber 33. The position of the longitudinal end 36 of the absorber recesses 34, the depth L1 of the absorber recesses 34, and the width direction length L3 of the absorber recesses 34 are set to appropriate values ​​capable of holding the male genitalia 1. The appropriate value for holding the male genitalia 1 may be derived through experiments, simulations, etc. In this embodiment, the non-skin side surface of the absorber 33 is formed in a substantially flat shape, but this is not limited to this.

[0037] Next, the men's absorbent article 10 in a worn state will be described with reference to the drawings. Fig. 6 is a longitudinal cross-sectional view of the men's absorbent article 10 in a worn state, viewed from the rear. Fig. 7 is a longitudinal cross-sectional view of the men's absorbent article 10 in a worn state, viewed from the side.

[0038] 2, 4, 6, and 7, when worn, the male genitalia 1 extends longitudinally within the insertion space 13, with part of the side of the male genitalia 1 fitting into the absorber recess 34 of the absorber 33. An area 37 of the absorber 33 on the one longitudinal side of the absorber recess 34 where no recess is provided is located closer to the base than the glans penis 1a of the male genitalia 1. The other side of the absorber recess 34 of the absorber 33 extends further toward the other longitudinal side than the male genitalia 1.

[0039] In the male absorbent article 10 configured as described above, the absorbent main body 30 is disposed on at least one side (both sides in this embodiment) of the insertion space 13 in a direction intersecting the longitudinal direction, and extends longitudinally from the bottom 12 to the end on the opening 11 side. The absorber 33 of the absorbent main body 30 has an absorber recess 34 that extends longitudinally and is recessed from the skin side to the non-skin side. Therefore, when worn, part of the side of the male genitalia 1 fits into the absorber recess 34 of the absorber 33 (see Figures 4 and 7), allowing the male genitalia 1 to be stably accommodated in the absorber recess 34, which holds the male genitalia 1 and prevents it from moving widthwise relative to the absorbent main body 30.

[0040] Furthermore, the top sheet 31 has a top sheet recess 31a that extends in the longitudinal direction while being recessed from the skin side to the non-skin side, and the top sheet recess 31a is arranged to align with and overlap the position of the absorber recess (recess) 34 of the absorber 33. Therefore, when worn, the male genitalia 1 can be held not only by the absorber recess 34 but also by the top sheet recess 31a, which further suppresses movement of the male genitalia 1 in the width direction relative to the absorbent main body 30.

[0041] In this way, according to this embodiment, it is possible to suppress the male genitalia 1 from shifting relative to the absorbent main body 30 when worn, thereby preventing urine leakage caused by the male genitalia 1 shifting relative to the absorbent main body 30.

[0042] In addition, a part of the side of the male genitalia 1 is inserted into the absorber recess 34 of the absorber 33, and the male genitalia 1 can be stored in the absorber recess 34, so that the gap between the male genitalia 1 and the absorbent main body 30 can be reduced and urine leakage can be prevented.

[0043] Furthermore, because the male genitalia 1 can be held in a state aligned with the absorbent recess 34, the direction of urine discharge from the male genitalia 1 (the orientation of the male genitalia 1) can be held in a state directed toward the bottom 12 of the male absorbent article 10. This minimizes the distance between the urinary excretion portion of the male genitalia 1 and the bottom 12 of the male absorbent article 10, making it easier for urine to be absorbed by the absorbent 33 of the bottom 12 of the male absorbent article 10.

[0044] Furthermore, because the other side of absorber recess 34 of absorber 33 extends to bottom 12 of men's absorbent article 10, urine can be guided by absorber recess 34 to bottom 12 of men's absorbent article 10. Therefore, urine can be absorbed not only by absorber 33 in the vicinity of the urinary excretion portion of male genitalia 1, but also by absorber 33 at bottom 12 of men's absorbent article 10, so urine can be efficiently absorbed using the entire absorber 33 rather than just a portion of it.

[0045] Furthermore, because the other side of the absorber recess 34 of the absorber 33 extends to the bottom 12 of the male absorbent article 10, even if the absorber 33 near the urinary excretion portion of the male genitalia 1 swells to form a dam 38, the height (length in the thickness direction) of the portion where the dam 38 occurs can be reduced. Figure 8 is an explanatory diagram of the formation of the dam 38, where (a) shows the male absorbent article 10 according to this embodiment and (b) shows a conventional male absorbent article. For example, as shown in Figure 8(a), in the male absorbent article 10 according to this embodiment, the male genitalia 1 is held in a state aligned with the absorber recess 34, and because the absorber recess 34 extends to the bottom 12 of the male absorbent article 10, urine excreted from the urinary excretion portion of the male genitalia 1 flows through the absorber recess 34. Even if urine discharged from the male genitalia 1 into the absorbent recess 34 causes the absorber 33 inside the absorber recess 34 to swell, forming a dam 38 near the male genitalia 1 (see FIG. 8(a)), the height of the part where the dam 38 has formed can be reduced, unlike when the dam 38 has formed in the absorber 33 of a conventional male absorbent article that does not have a recess in the absorber 33 (see FIG. 8(b)). This makes it possible to prevent urine from being blocked, and since urine is more likely to move to the other side in the longitudinal direction than the dam 38, the urine can be guided toward the bottom 12 of the male absorbent article 10, and urine can be efficiently absorbed using the entire absorber 33 rather than just a part of it.

[0046] Furthermore, the absorber recess 34 of the absorber 33 extends from a position spaced from the opening 11 toward the other longitudinal side of the male absorbent article 10 to the bottom 12. That is, a region 37 where no recess is provided exists on the one longitudinal side of the absorber recess 34 of the absorber 33. Therefore, by appropriately setting the position of the end 36 on the one longitudinal side of the absorber recess 34, the depth L1 of the absorber recess 34, and the widthwise length L3 of the absorber recess 34, as shown in FIGS. 7 and 8(a), the region 37 where no recess is provided of the absorber 33 can be positioned closer to the base of the glans 1a of the male genitalia 1 when the absorber 33 is worn. As a result, if a dam 38 is formed in the absorber 33, the height of the absorber 33 at the portion where the dam 38 is formed can be reduced, as described above.

[0047] Furthermore, since there is an area 37 of the absorber 33 on the one longitudinal side of the absorber recess 34, even if excreted urine hits the bottom 12 of the male absorbent article 10 and returns to the one longitudinal side, there is no portion that serves as a urine flow path from the absorber recess 34 to the opening 11. Therefore, the absorber 33 in the area 37 on which no recess is provided can suitably absorb the urine that returns from the bottom 12 side, and urine leakage from the opening 11 can be prevented.

[0048] Furthermore, since the region 37 of the absorber 33 where no recesses are provided can be positioned closer to the base than the glans 1a of the male genitalia 1 when worn, the bulge of the glans 1a of the male genitalia 1 can be fitted into the end 36 on one side in the longitudinal direction of the absorber recess 34 (the step between the region 37 where no recesses are provided and the absorber recess 34) (see Figure 7). Therefore, the glans 1a of the male genitalia 1 can prevent urine from moving from the absorber recess 34 side to the gap between the region 37 of the absorber 33 where no recesses are provided and the male genitalia 1, thereby preventing urine leakage from the opening 11.

[0049] Furthermore, the absorber recess 34 of the absorber 33 extends in the longitudinal direction, recessed from the skin side to the non-skin side, allowing a portion of the side of the male genitalia 1 to fit into the absorber recess 34 of the absorber 33 when worn (see FIGS. 4 and 7). The non-skin side surface of the absorber 33 is formed in a substantially flat shape, and the thickness of the absorber recess 34 of the absorber 33 is thinner than the thickness of other areas of the absorber 33. This prevents the male absorbent article 10 from expanding (in the front-to-back direction) within the outer 2 when worn, thereby preventing the outer 2 from floating (from the body) due to the expansion of the male absorbent article 10 and reducing the occurrence of gaps between the outer 2 and the body. For example, the floating of the disposable diaper (outer 2) due to the expansion of the male absorbent article 10 can be kept within the height range of the three-dimensional gathers of the disposable diaper, thereby reducing the occurrence of gaps between the disposable diaper and the body. This allows the outer garment 2 to fit snugly against the body, so that even if urine leaks from the men's absorbent article 10, the urine can be prevented from leaking outside the outer garment 2.

[0050] Furthermore, it is preferable that the depth L1 of the absorber recess 34 is set to a depth equal to or greater than half the thickness L2 of the absorber 33. This allows the depth L1 of the absorber recess 34 to be set deep so as to suitably hold the male genitalia 1. Furthermore, the depth L1 of the absorber recess 34 can be set deep in order to suppress the height of the portion where the dam 38 occurs.

[0051] In this embodiment, the longitudinal end 36 of the absorbent recess 34 of the absorbent 33 is positioned closer to the bottom 12 (the other longitudinal side) than the longitudinal end 35 of the absorbent main body 30, but this is not limited to this, and the longitudinal side of the absorbent recess 34 of the absorbent 33 may be extended to the longitudinal end 35 of the absorbent main body 30.

[0052] In the present embodiment, the other longitudinal sides of the absorber recesses 34 in both the front region 30a and the rear region 30b of the absorbent main body 30 are connected to each other at the bottom 12, but this is not limitative. For example, separate absorber recesses 34 that are not connected to each other at the bottom 12 may be provided in each of the front region 30a and the rear region 30b of the absorbent main body 30, and no absorber recess 34 may be provided in the central portion of the bottom 12 in the width direction.

[0053] Furthermore, in this embodiment, the absorber recess 34 is formed as a groove having a U-shaped cross section and a bottom, but the cross-sectional shape of the absorber recess 34 is not limited to a U-shaped cross section. Fig. 9 is a cross-sectional view in the width direction of the absorber 33 showing a modified example of the cross-sectional shape of the absorber recess 34. For example, as shown in Fig. 9, the absorber recess 34 may be formed as a groove having a V-shaped cross section and a bottom.

[0054] Furthermore, in this embodiment, the absorbent recess 34 is formed as a groove with a bottom, but this is not limited thereto. The recess may extend in the longitudinal direction while recessed from the skin side to the non-skin side. Here, "recessed from the skin side to the non-skin side" simply means that there is a step recessed from the skin side to the non-skin side, and does not limit the presence or absence of a bottom. FIG. 10 is a widthwise cross-sectional view of the men's absorbent article 10 in an unfolded state, showing a modified absorbent recess 34. FIG. 11 is a longitudinal cross-sectional view of the men's absorbent article 10 in an unfolded state, showing a modified absorbent recess 34. For example, as shown in FIGS. 10 and 11, the absorbent recess 34 may be formed as an elongated hole that penetrates the absorbent 33 in the thickness direction, extends in the longitudinal direction, and recesses from the skin side to the non-skin side.

[0055] In addition, in this embodiment, the absorbent recess 34 is provided in both the front region 30a and the rear region 30b of the absorbent main body 30, but this is not limited to this, and the absorbent recess 34 may be provided in only one of the front region 30a and the rear region 30b.

[0056] Furthermore, in this embodiment, the absorbent main body 30 (front region 30a and rear region 30b) is provided on both sides of the insertion space 13 in a direction intersecting the longitudinal direction, but this is not limited thereto, and the absorbent main body 30 may be provided on at least one side of the insertion space 13 in a direction intersecting the longitudinal direction. FIG. 12 is an explanatory diagram showing a modified example of the male absorbent article 10. FIG. 13 is a plan view showing a modified example of the male absorbent article 10 in an unfolded state. As shown in FIGS. 12 and 13, the absorbent main body 30 may be provided only on one side of the insertion space 13 in a direction intersecting the longitudinal direction (the front side in the drawings). In this case, it is preferable to wear the male absorbent article 10 so that the absorbent main body 30 is located in front of the male genitalia 1, as shown in FIGS. 12 and 13.

[0057] Next, a second embodiment of the present invention will be described with reference to the drawings. Men's absorbent article 40 of this embodiment differs from the first embodiment in that absorber 33 has branch recesses 41 in addition to absorber recesses 34. Note that components similar to those of the first embodiment are designated by the same reference numerals and will not be described again.

[0058] Figure 14 is a plan view of a men's absorbent article 40 according to a second embodiment of the present invention in an unfolded state, with (a) showing a state in which the branch recessed portions 41 are inclined and (b) showing a state in which the branch recessed portions 41 extend in the width direction. Note that although Figure 14 shows men's absorbent article 40 in an unfolded state, men's absorbent article 40 is formed in a bag shape, similar to the first embodiment described above.

[0059] The men's absorbent article 40 of this embodiment comprises an outer body 20 that forms the bag-shaped outer shape of the men's absorbent article 40, and an absorbent main body 30 that is attached to the inner surface (skin side) of the outer body 20.

[0060] As shown in Figures 14(a) and (b), the absorbent body 33 of the absorbent main body 30 has an absorbent body recess (recess) 34 and multiple branch recesses 41 extending in the longitudinal direction while recessed from the skin side to the non-skin side. In this embodiment, each branch recess 41 is formed as a groove with a bottom and a U-shaped cross section recessed from the skin side to the non-skin side. The multiple branch recesses 41 extend continuously from the absorbent body recess 34 toward the outside on both sides in the width direction (in directions intersecting with the absorbent body recess (recess) 34). The multiple branch recesses 41 are arranged symmetrically in the width direction with the absorbent body recess 34 as the center.

[0061] 14(a), in one aspect of a men's absorbent article 40 according to this embodiment, the branch recesses 41 extend from the absorber recess 34 outward in the width direction and toward the one longitudinal side (the opening 11 side) at an angle relative to the longitudinal direction. In this embodiment, the branch recesses 41 include a pair of branch recesses 41a, 41b extending outward in the width direction and toward the one longitudinal side from a position spaced from the one longitudinal end 36 of the absorber recess 34 toward the other side, and a pair of branch recesses 41c, 41d extending outward in the width direction and toward the one longitudinal side from a position spaced from the other longitudinal side from the pair of branch recesses 41a, 41b of the absorber recess 34. The tip ends of the pair of branch recesses 41a, 41b are located on the one side of the one longitudinal end 36 of the absorber recess 34. The pair of branch recesses 41c, 41d are arranged on the one longitudinal side of the bottom 12. The distal ends of the pair of branch recesses 41c, 41d are arranged at approximately the same position in the longitudinal direction as the proximal ends of the pair of branch recesses 41a, 41b. The branch recesses 41a-41d are provided in both the front region 30a and the rear region 30b of the absorbent main body 30.

[0062] As shown in FIG. 14(b), in another aspect of the men's absorbent article 40 according to this embodiment, the branch recesses 41 extend outward in the width direction from the absorber recess 34, perpendicular to the longitudinal direction. In this embodiment, the branch recesses 41 include a pair of branch recesses 41e, 41f extending outward on both width directions from the end 36 on one longitudinal side of the absorber recess 34, and a pair of branch recesses 41g, 41h positioned at a distance from the pair of branch recesses 41e, 41f to the other longitudinal side. The pair of branch recesses 41g, 41h are positioned on the one longitudinal side of the bottom 12. The branch recesses 41e-41h are provided in both the front region 30a and the rear region 30b of the absorber main body 30.

[0063] In the male absorbent article 40 configured as described above, the absorber 33 of the absorber main body 30 has a plurality of branch recesses 41 that extend outward on both sides in the width direction (in directions that intersect with the absorber recess (recess) 34) continuously from the absorber recess 34. Therefore, the branch recesses 41 can suppress longitudinal movement of the male genitalia 1 relative to the absorber main body 30.

[0064] In this way, according to this embodiment, it is possible to suppress the male genitalia 1 from shifting relative to the absorbent main body 30 when worn, thereby preventing urine leakage caused by the male genitalia 1 shifting relative to the absorbent main body 30.

[0065] Furthermore, the absorber 33 of the absorber main body 30 has a plurality of branch recesses 41 that are continuous from the absorber recess 34 and extend outward on both sides in the width direction, so that urine can be guided from the absorber recess 34 to the widthwise outer side of the absorber 33 by the plurality of branch recesses 41. Therefore, urine can also be absorbed by the absorber 33 on the widthwise outer sides of the absorber main body 30, so that urine can be efficiently absorbed by utilizing the entire absorber 33, rather than just a portion of it. Furthermore, urine can be guided from the widthwise outer sides of the absorber 33 to the absorber recess 34 in the widthwise center by the plurality of branch recesses 41. Therefore, urine can be guided from the widthwise outer sides of the absorber 33 to the bottom 12 via the plurality of branch recesses 41 and the absorber recess 34, so that urine can be efficiently absorbed by utilizing the entire absorber 33, rather than just a portion of it.

[0066] Furthermore, as shown in Figure 14(a), when multiple branch recesses 41 are inclined relative to the longitudinal direction, the length of the branch recesses 41 can be increased, which allows urine to be guided to a wider area of ​​the absorber 33, and urine can be efficiently absorbed by utilizing the entire absorber 33 rather than just a part of it.

[0067] The number of branch recesses 41 provided is not limited to the above, and it is sufficient that at least one branch recess 41 is provided.

[0068] In addition, in this embodiment, the branch recess 41 is formed as a groove with a U-shaped cross section and a bottom recessed from the skin side to the non-skin side, but the cross-sectional shape of the branch recess 41 is not limited to a U-shaped cross section and may be, for example, a V-shaped cross section. Alternatively, the branch recess 41 may be formed as an elongated hole that penetrates the absorbent body 33 in the thickness direction and extends in a recessed state from the skin side to the non-skin side.

[0069] Furthermore, in this embodiment, the branch recesses 41 are provided symmetrically in the width direction with the absorber recess 34 at the center, but this is not limitative, and they may be provided asymmetrically in the width direction.

[0070] In addition, in this embodiment, the absorbent body recess 34 and multiple branch recesses 41 are provided in both the front region 30a and the rear region 30b of the absorbent main body 30, but this is not limited to this, and the absorbent body recess 34 and multiple branch recesses 41 may be provided in only one of the front region 30a and the rear region 30b.

[0071] Furthermore, as in the first embodiment described above, the absorbent body 30 only needs to be provided on at least one side in the direction intersecting the longitudinal direction of the insertion space 13, and if it is provided on only one side, it is preferable to wear the male absorbent article 10 so that the absorbent body 30 is positioned in front of the male genitalia 1.

[0072] Furthermore, in the first and second embodiments, the unfolded outer body 20 is folded in half along the longitudinal center line CL so that the absorbent main body 30 is on the inside, and the side flaps 14 on both sides in the width direction are fixed to each other to form the men's absorbent article 10, 40 into a bag shape, but the manufacturing method of the men's absorbent article 10, 40 is not limited to this.

[0073] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
