For example, in the following Patent Document 1, a fold extending in the first direction is folded with the topsheet facing inward, and the outer surface of the absorber crosses the fold at both ends in the first direction. A male incontinence pad is disclosed that has an elongated elastic member attached thereto.

Moreover, in the following Patent Document 2, the outer shape of the absorbent article is formed in a substantially inverted triangular shape in a plan view as viewed from the user side, the absorber has an upper layer absorber and a lower layer absorber, and the upper layer absorber However, there is disclosed an absorbent article that is formed in a substantially V shape in plan view, is formed in a substantially V shape along the upper layer absorbent body, and has channel embossing from the top sheet to the lower layer absorbent body. ing.

JP 2016-116722 A Japanese Unexamined Patent Publication No. 2016-42946

Since the absorbent article for men is attached to the lower side of the front surface of the undergarment due to the relationship with the urination site, the skin contact surface is almost parallel to the vertical direction in the worn state. For this reason, the discharged urine has a problem that it tends to flow downward due to gravity and easily leaks from the lower end of the absorbent article for men.

In the incontinence pad for men described in Patent Document 1, the incontinence pad for men is formed in a cup shape that bulges outward due to the contraction force of the elastic member. The urine thus produced tends to flow downward due to gravity, easily leaks from the lower end, and the absorber above the urination site cannot be effectively utilized.

In addition, the absorbent article described in Patent Document 2 has a substantially V-shaped upper layer absorbent body to prevent lateral leakage in the left-right direction and transmission leakage to the rear side, corresponding to a male urination position that is difficult to determine in underwear. Although it is to prevent, when the thick part of the absorber is provided by the upper-layer absorber, a sense of incongruity at the time of wearing tends to occur. In addition, since a substantially V-shaped channel embossing is formed, the flow of urine downward is considered to be blocked to some extent, but since only one channel embossing is provided, the surface is The blocking effect of flowing urine and urine diffusing in the absorbent body was not sufficient, and there was a risk of leakage from the lower end.

Therefore, a main problem of the present invention is to provide a male absorbent article that prevents leakage of urine without giving the wearer a sense of incongruity.

In order to solve the above-mentioned problem, as the present invention according to claim 1, in the absorbent article for men in which an absorbent body is interposed between the liquid-permeable surface sheet and the liquid-impermeable back sheet,
An absorbent article for men, wherein a plurality of embossing embossments having a shape projecting downward in a plan view are provided in the lower half region of the absorbent article for men. Is provided.

As described above in detail, according to the present invention, it is possible to provide a male absorbent article that does not feel uncomfortable at the time of wearing and can reliably prevent leakage of urine.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First embodiment]
(Basic configuration of male incontinence pad 1)
As shown in FIGS. 1 and 2, the male incontinence pad 1 according to the first embodiment is a liquid-impermeable back sheet 2 made of a polyethylene sheet, a polypropylene sheet, or the like, and a liquid-permeable material that quickly permeates urine and the like. The absorbent surface sheet 3, the absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the both

sheets

2 and 3, and the absorbent body 4 for maintaining the shape and improving the diffusibility of the absorbent body 4 It is comprised from the wrapping sheet | seat 5 which consists of a crepe paper or a nonwoven fabric etc. which covers at least a skin side surface and a non-skin side surface. In addition, the outer edge portion of the liquid-impervious back sheet 2 and the liquid-permeable top sheet 3 is bonded around the absorber 4 by an adhesive such as hot melt, or an adhesive means such as heat seal or ultrasonic seal. The flap part which does not have the absorber 4 is formed in the outer periphery.

Hereinafter, the structure of the male incontinence pad 1 will be described in detail. As the liquid-impermeable back sheet 2, a sheet material having at least a water shielding property such as an olefin resin sheet such as polyethylene or polypropylene is used. In addition, a laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, and further, a waterproof film is provided to ensure substantially liquid impermeability, and then a nonwoven fabric sheet (in this case, the waterproof film and the nonwoven fabric are impermeable to liquid. Can be used. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. This water- and moisture-permeable sheet material is a microporous sheet obtained by forming a sheet by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretching in a uniaxial or biaxial direction. It is.

Next, the liquid-permeable surface sheet 3 is preferably a porous or non-porous nonwoven fabric or a porous plastic sheet. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and the spunbond method is excellent in drapeability, and the thermal bond method and the air-through method are excellent in terms of being bulky and having high compression recovery properties. The non-woven fiber may be either a long fiber or a short fiber, but preferably a short fiber is used in order to give a towel texture. In order to facilitate the embossing treatment, it is preferable to use an olefin fiber such as polyethylene or polypropylene having a relatively low melting point. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can be suitably used.

(Absorber 4)
The absorbent body 4 interposed between the liquid-impermeable back sheet 2 and the liquid-permeable surface sheet 3 is, for example, a mixture of a superabsorbent resin in pulp or a mixture of chemical fibers in the pulp. In addition, those mixed with a superabsorbent resin are used. As shown in the figure, it is desirable that the absorbent body 4 is covered with an encapsulating sheet 5 in order to maintain its shape and to quickly diffuse urine and to prevent the urine once absorbed from returning. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as molten pulp, and those made of artificial cellulose fibers such as rayon and acetate. It is preferably used in terms of price. Moreover, as the absorbent body 4, an airlaid absorbent body that can reduce the volume, or a polymer sheet in which a superabsorbent resin is disposed between two nonwoven fabric layers may be used.

Further, synthetic fibers may be mixed in the absorber 4. As the synthetic fiber, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It may be a mixture. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can be used. In the case of a hydrophobic fiber, it is desirable to use a synthetic fiber that has been surface-treated with a hydrophilizing agent so as to have an affinity for body fluids.

Examples of the superabsorbent resin include cross-linked polyacrylate, self-crosslinked polyacrylate, saponified acrylate-vinyl acetate copolymer cross-linked, isobutylene / maleic anhydride copolymer cross-linked, Examples include cross-linked polysulfonates, and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. Among these, those based on acrylic acid or acrylate that are excellent in water absorption and water absorption speed are preferred. In the production process of the highly water-absorbent resin having the water absorption performance, the water absorption force and the water absorption speed can be adjusted by adjusting the crosslinking density and the crosslinking density gradient. The content of the highly water-absorbent resin is desirably 5 to 60% of the weight of the absorber. When the content of the superabsorbent resin is less than 5%, sufficient absorbability cannot be provided, and when it exceeds 60%, the entanglement between the pulp fibers disappears, the sheet strength decreases, and tears, cracks, etc. Is likely to occur.

At least the skin side and the non-skin side of the absorbent body 4 are covered with an encapsulating sheet 5 made of crepe paper or nonwoven fabric. As a method of covering the absorbent body 4 with the encapsulating sheet 5, a known method can be adopted. (1) As shown in FIG. 3 (A), both sides of the continuous absorbent body before cutting are cut before cutting. (2) Absorber 4 stacked in a predetermined planar shape as shown in FIG. 3 (B), in which the continuous encapsulated sheets are laminated and these laminated bodies are integrally cut into a predetermined shape. The encapsulating sheet 5 having a planar shape larger than the absorbent body 4 (size and shape so that the absorbent body 4 does not protrude in a plan view) is laminated on both sides of the absorbent body 4, and encapsulated at a portion extending outside the absorbent body 4 A form in which the

sheets

5 and 5 are joined to each other, and the periphery thereof is cut out into a predetermined shape. (3) As shown in FIG. It can be any one of the forms that surround the frame. When the shape of the absorber 4 in plan view is a circular shape or an inverted triangle shape, the form (1) or (2) can be adopted, and when the shape of the absorber 4 in plan view is a square shape or the like. The above-mentioned form (3) can also be adopted.

As in this example, when the encapsulating sheet 5 covering the absorber 4 is provided, the encapsulating sheet 5 is interposed between the liquid-permeable surface sheet 3 and the absorber 4 as a result. In the case where the encapsulating sheet 5 is made of crepe paper, the urine is quickly diffused by the encapsulating sheet 5 having excellent absorbability, and reversion of the urine is prevented.

In the absorbent body 4, it is preferable that the lower half of the male incontinence pad 1 has a larger amount of the pulp and the superabsorbent resin than the upper half. Thereby, the leakage prevention effect can be promoted by increasing the absorption capacity of the lower half and increasing the amount of urine that can be absorbed and held in the absorbent body 4. This configuration is particularly effective when the absorber 4 has a vertically symmetric plan view shape, and as shown in FIG. 5A, when the absorber 4 has a vertically asymmetric plan view shape, the lower half plane is particularly effective. When the visual shape is small, it is not preferable that the amount of the pulp and the superabsorbent resin is excessively increased because the absorbent body 4 becomes thicker or harder and the wearing feeling may be lowered. The rate of increase in the amount of pulp and the amount of superabsorbent resin is about 120% to 200%, preferably about 120% to 150% in weight ratio compared to the upper half.

One or both of the absorber 4 and the encapsulating sheet 5 preferably have a color other than white, preferably a color with a relatively low brightness such as black or gray. Since the present invention relates to an incontinence pad for men, a relatively dark color is used to give a calm impression for men, and it is less noticeable when worn on dark underwear, and traces of urination are less noticeable. . The coloring method is not particularly limited, and an appropriate dyeing method or a coloring material can be used. Moreover, you may give coloring by containing activated carbon in any one or both of the absorber 4 and the encapsulating sheet 5. FIG. Thereby, the deodorizing effect by activated carbon can also be added.

As a modification of the absorbent body 4, as shown in FIG. 4, it may be formed so that the thickness of the absorbent body 4 is thinner at the peripheral part than at the center part. In order to form the peripheral portion of the absorbent body 4 relatively thinly, when a raw material such as pulp is sucked with vacuum to pile up in an actual product, due to non-uniform vacuum pressure, etc. When the thickness of the portion close to the periphery is formed thin, and by applying a plurality of blocking embossing 10 described later, the width divided by the adjacent blocking

embossing

10 and 10 is relatively In a small region, since the restoring force of the absorbent body 4 after compression is small and the stretch of the liquid-permeable surface sheet 3 due to compression is small, the absorbent body 4 can be formed with a thin thickness or a combination thereof.

(Emboss 10 for blocking)
In the male incontinence pad 1 according to the first embodiment, as shown in FIG. 1, a planar view shape (planar shape may be referred to as a planar shape) protrudes downward in the lower half region of the male incontinence pad 1. In other words, a plurality of embossing embossing elements 10 having a shape protruding downward in plan view are provided. In this specification, “projecting downward” refers to being curved so as to be convex downward as a whole. In the male incontinence pad 1, the embossing 10 for blocking is provided only in the lower half region of the male incontinence pad 1, and the embossing is not provided in the upper half region, and the surface is substantially flat. Is formed.

By providing the embossing 10 for blocking in the lower half area of the male incontinence pad 1, the following effects can be obtained. Since the male incontinence pad 1 is attached to the lower side of the front surface of the undergarment in relation to the urination site H due to the structure of the male human body, the skin contact surface is arranged substantially parallel to the vertical direction in the worn state. The Therefore, the urine discharged to the urination site H diffuses downward due to gravity. At this time, there are urine that diffuses downward due to gravity, that flows on the surface of the liquid-permeable surface sheet 3, and urine that is absorbed by the absorber 4 diffuses in the absorber 4. The urine flowing on the surface of the former liquid-permeable surface sheet 3 enters the concave groove of the embossing 10 for blocking in the process of flowing downward, and the flow toward the lower side is blocked. Moreover, the urine diffusing in the latter absorber 4 is blocked by the embossing 10 for blocking, in which the absorber 4 is consolidated. Thus, since both the urine flowing on the surface of the liquid-permeable surface sheet 3 and the urine diffusing in the absorber 4 are blocked by the embossing 10 for blocking, leakage from the lower end portion is prevented. It can be surely prevented.

Furthermore, since a plurality of the embossing stoppers 10 are provided, the amount of urine that diffuses downward gradually decreases by being repeatedly blocked by the embossing stopper 10, and more reliably leaks. Can be prevented.

Moreover, it is the embossing 10 for blocking that blocks the urine flowing downward, and there is no thick part of the absorber as in the conventional male absorbent article. Can be greatly reduced.

Hereinafter, the embossing 10 for blocking will be described in more detail. The embossing 10 for blocking is provided only in the lower half region of the male incontinence pad 1 and is not provided in the upper half region. The lower half region of the male incontinence pad 1 is a region below the width direction center line Lh that bisects the vertical length of the male incontinence pad 1 in the wearing state (the wearer's crotch side). That is. Further, the upper half area of the male incontinence pad 1 is an area above (the abdomen side of the wearer) the width direction center line Lh. Thus, in the male incontinence pad 1, since the embossing 10 for blocking is not provided in the upper half area, the diffusion of urine to the upper area is not hindered, and the upper half area is It can be effectively used as a urine absorption region. In the lower half region, each embossing 10 for blocking extends so as to bulge in a direction away from the center line Lh in the width direction.

The embossing 10 for blocking is a concave groove that is depressed from the liquid-permeable surface sheet 3 to the absorber 4 by being integrally compressed from the outer surface side of the liquid-permeable surface sheet 3 to the absorber 4. The embossing 10 for blocking can be processed using a known method. For example, in a state where the liquid-permeable surface sheet 3 is laminated on the upper surface of the absorbent body 4 covered with the encapsulating sheet 5, the permeable roll is provided with a convex roll provided with a convex portion corresponding to the embossing 10 for blocking. It can process by giving heat embossing from the upper surface side of the liquid surface sheet 3. FIG.

As shown in FIG. 1, each embossing 10 for blocking has end edges 10 a and 10 a arranged in line symmetry with respect to the center line Lv in the vertical direction of the male incontinence pad 1 in plan view. It is formed in the shape of a continuous line that protrudes downward from the

end edges

10a, 10a. That is, each embossing 10 for blocking is curved so that the end edges 10a and 10a are located at the uppermost position. Further, the plurality of

embossing bosses

10, 10... Are provided independently, and the end edges are not connected to each other. For this reason, the urine that goes around the edge of the inner embossing embossing 10 and diffuses to the outside can be blocked by the outer embossing embossing 10 to prevent leakage of urine more reliably. Has the advantage of being able to. The embossing 10 for blocking is preferably formed in a shape projecting downward in the vertical direction with the intersection with the vertical center line Lv of the male incontinence pad 1 as the top.

The plan view shape of the embossing 10 for blocking may be a shape that protrudes downward as a whole, but is preferably formed in a shape substantially along the outer shape of the absorbent body 4, and the urination site H is formed. It is also a preferable form that a plurality of

embossing embossings

10, 10... Are arranged concentrically at the center.

When the plan view shape of the embossing 10 for blocking is formed substantially along the outer shape of the absorber 4, it can be arbitrarily changed depending on the outer shape of the absorber 4. The male incontinence pad 1 may have an outer shape such as (A) inverted triangle or (B) square shown in FIG. 5 in addition to the circle shown in FIG. It is also possible to adopt a known shape. At this time, the outer shape of the absorber 4 is formed so as to substantially follow the outer shape of the male incontinence pad 1, and the embossing 10 for blocking is formed substantially along the outer shape of the absorber 4. Specifically, as shown in FIG. 1, when the absorber 4 is formed in a circular shape, the embossing 10 for blocking is formed in a substantially semicircular shape, and is shown in FIG. 5 (A). Thus, when the absorber 4 is formed in an inverted triangle shape, the embossing 10 for blocking is formed in a substantially V shape along the outer shape of the absorber 4 and is shown in FIG. Thus, when the said absorber 4 is formed in a rectangular shape, the embossing 10 for blocking | blocking is formed in the substantially U-shape or U-shape by which upper direction was open | released.

Further, the planar view shape of the embossing 10 for blocking may not be a shape along the outer shape of the absorber 4. For example, as shown in FIGS. 5 (C) and 5 (D), the absorber 4 may be formed in an arc shape on a substantially inverted triangle or quadrangle. Further, as shown in FIG. 6 (A), the circular absorbent body 4 may be formed in a semi-elliptical shape or an arc shape that is long in the width direction of the male incontinence pad 1. As shown in (B), it may be formed in a substantially V shape in which a curve or straight line with a large curvature radius extends obliquely upward on both sides from the vertical center line Lv. As shown in FIG. 6A, in the case of forming in a horizontally long plan view shape, the ratio (d / c) of the length d protruding in the width direction to the length c protruding in the vertical direction is 1.1. It is preferably about 1.5. Thereby, the spreading | diffusion to the width direction is promoted rather than the lower side, and the leak from the downward direction can be prevented.

As shown in FIGS. 1 and 6, the blocking emboss 10 includes an imaginary line S connecting the edge 10 a of the blocking emboss 10 and the intersection of the vertical center line Lv and the vertical center line. The angle α formed with Lv is 45 ° or more, preferably 45 ° to 80 °, more preferably 45 ° to 60 °. Thereby, it is possible to prevent the urine blocked by the embossing 10 for blocking from being rapidly concentrated on the central part by gravity along the embossing 10 for blocking, and it is difficult for leakage from the central part to occur. Become.

The embossing 10 for blocking is formed in a plurality of strips, preferably 2 to 6 strips on the outward side around the urination site H, and 3 strips in the illustrated example. The plurality of embossing bosses 10 for blocking are arranged independently without being connected to each other.

As shown in FIG. 1, the distance a between the adjacent embosses 10 and 10 for blocking is preferably 5 to 30 mm, particularly 7 to 15 mm. This interval may be substantially equal over the entire length of the embossing 10 for blocking, or may be partially different. For example, the interval between the embosses 10 and 10 adjacent on the inner side of the male incontinence pad 1 may be different from the interval between the embosses 10 and 10 adjacent on the outer side, and as shown in FIG. A portion with a narrow interval and a wide portion may be provided along the direction in which the embossing 10 extends, or these may be combined.

In the embodiment shown in FIG. 7, the distance between the central portions of the embossing stopper 10 (intersection with the vertical center line Lv) is larger than the distance between both end portions of the embossing stopper 10. Has been. That is, the density of the embossing 10 for blocking is relatively low at the center and relatively high at both ends. As a result, the urine that tends to flow downward due to gravity is reliably blocked in the central portion, and leakage can be prevented more reliably, and at both ends, the urine can be spread over a wider range, and the urine absorption capacity can be increased. It can be secured.

As shown in FIG. 1, it is preferable that the minimum separation distance b between the embossing 10 for blocking and the edge of the absorber 4 arranged on the outermost side is 5 to 20 mm. If it is smaller than 5 mm, urine leakage is likely to occur, and if it is larger than 20 mm, a plurality of embossing stoppers 10 are concentrated in the central portion, which is not preferable.

It is preferable that the end edge 10a of the embossing 10 for blocking is provided in the vicinity of the center line Lh in the width direction. That is, the embossing 10 for blocking is preferably provided over almost the entire lower half of the male incontinence pad 1. The distance in the vertical direction of the pad between the edge 10a of the embossing 10 for blocking and the center line Lh in the width direction is 0 to 20 mm, preferably 3 to 10 mm. In the example shown in FIG. 1, the separation distance between the edge 10 a and the center line Lh in the width direction is substantially the same in all the embossing elements 10 for blocking, but the blocking distance arranged on the inner side. The embossing 10 may be formed so that the separation distance gradually increases or decreases. When the inner embossing embossing 10 is formed so that the separation distance becomes larger, the urine diffused outward from the edge of the inner embossing embossing 10 is removed by the outer embossing embossing 10. It becomes easy to block. On the other hand, when the inner embossing embossing 10 is formed so that the separation distance becomes smaller, the urine is more securely blocked on the inner side, and the compression length by the outer embossing embossing 10 is greater. Since it is short, it is hard to be hard and the wearing feeling is advantageous.

The groove width of the embossing 10 for blocking is 1 to 4 mm, preferably 1.5 to 3 mm. When the groove width is smaller than 1 mm, a sufficient blocking effect cannot be obtained. If the groove width exceeds 4, the hardness may be increased and the wearing feeling may be deteriorated. The groove width may be constant, or may be partially different, for example, relatively thick at the center of the embossing 10 for blocking in order to enhance the blocking effect.

Further, the plurality of embossing

embossing elements

10, 10... Need not all have the same shape, and may be formed in partially different shapes. For example, as shown in FIG. 5 (A) or FIG. 6 (B), when the embossing 10 for blocking is formed in a substantially V shape as a whole, the blocked urine tends to concentrate on the central part. Since there is a possibility that urine leakage may occur through the central portion, it is preferable to form a part of the tip of the plurality of embossing embossments 10 in a W shape as shown in FIG. As a result, body fluid concentrated on the tip side by gravity can be dispersed in the two protrusions, and urine leakage can be prevented. It is more preferable to alternately arrange one having a V-shaped tip and one having a W-shaped tip.

As shown in FIGS. 1 and 5, the male incontinence pad 1 has an elastic elastic member 11 stretched and fixed to the flap portion in the lower half region, thereby, as shown in FIG. In a state in which the contraction force of the elastic elastic member 11 is applied, at least the lower half region of the male incontinence pad 1 bulges outward from the center of the male incontinence pad 1 by the contraction force of the elastic elastic member 11. It is preferable that it is formed in a cup shape. In particular, as shown in FIG. 4, in the case of the absorbent body 4 having a relatively thin peripheral edge, the outer peripheral part of the absorbent body 4 is easily deformed by the contraction force of the elastic elastic member 11. Thus, the lower half region of the male incontinence pad 1 is easily formed in a cup shape.

By forming the male incontinence pad 1 in a cup shape by the contraction force of the elastic elastic member 11, the speed at which the discharged urine flows downward due to gravity is reduced, and leakage of urine can be prevented. When the incontinence pad 1 is taken out and attached to the undergarment, it becomes easy to distinguish the upper and lower sides, and errors in the direction of attachment to the undergarment are reduced.

The direction in which the elastic elastic member 11 is disposed is preferably a direction substantially along the outer shape of the male incontinence pad 1 as shown in FIGS. As shown in FIG. 1, in the male incontinence pad 1 having a circular outer shape, an arc shape substantially parallel to the circular outer shape line at the lower end flap portion or a straight shape along the width direction of the male incontinence pad 1 (FIG. 1). In the example). The male incontinence pad 1 having a substantially inverted triangle shape shown in FIG. 5 (A) can be arranged on the flap portions on both sides of the lower half region, and the rectangular male shape shown in FIG. 5 (B). The incontinence pad 1 can be disposed at the lower end of the lower half region and the flap portions on both sides.

The elastic elastic member 11 may be disposed only in the flap portion, or may be disposed in a position where a part or all of the elastic elastic member 11 overlaps the side edge of the absorber 4. The elastic elastic member 11 can be arranged in one or a plurality of strips.

As the elastic elastic member 11, a rubber thread, a tape-like elastic member, or the like can be used. The elongation rate when fixed (meaning the natural length as 100%) is 120 to 300%
It is preferable to set the degree.

[Second embodiment]
Next, a male incontinence pad 1A according to a second embodiment will be described with reference to FIGS. For simplification of description, the same reference numerals are given to the same configurations as those in the first embodiment, and detailed description thereof is omitted.

As shown in FIGS. 10 and 11, the male incontinence pad 1A according to the second embodiment is provided with embossing embossing similar to the male incontinence pad 1 according to the first embodiment in the lower half region. 10 and a plurality of liquid diffusion embosses 12 having a plan view shape extending radially from the urination site H, that is, a shape extending radially from the urination site H in plan view, are provided in the upper half region. It has been.

By providing the liquid diffusion emboss 12, the urine absorbed by the absorbent body 4 at the urination site H is the upper half region of the male incontinence pad 1A along the liquid diffusion emboss 12 that is consolidated by capillary action. It becomes easy to diffuse, and it becomes possible to effectively utilize the upper half region from the urination site H. Further, by guiding upward the urine that tends to flow downward from the urination site H due to gravity, the amount of urine flowing to the lower region can be reduced, and leakage of urine can be prevented.

The liquid diffusion emboss 12 has an intersection 12a where all the liquid diffusion embosses 12 intersect within the urination site H, and extends radially from the intersection 12a. The direction in which the liquid diffusion emboss 12 extends is one or both of the width direction and the upper direction of the male incontinence pad 1A from the intersection point 12a, and does not extend in the direction below the intersection point 12a. .

The liquid diffusion emboss 12 is preferably a continuous straight line so that urine can easily diffuse along the emboss. It is preferable that the side edge exists inside the outer edge of the absorbent body 4. The minimum separation length e between the edge of the liquid diffusion emboss 12 and the outer edge of the absorber 4 is arbitrary, but is preferably 3 to 10 mm.

The liquid diffusion emboss 12 is provided only in the upper half area of the male incontinence pad 1A, and is not provided in the lower half area. Assuming that the liquid diffusion emboss 12 is provided in the lower half region from the urination site H, the liquid diffusion emboss 12 makes the urine that easily flows downward due to gravity easily flow downward. Therefore, the amount of liquid absorbed in the lower half is further increased, and leakage is likely to occur.

The liquid diffusion emboss 12 is provided at a predetermined interval from the embossing 10 without being connected to the embossing 10 formed on the lower half.
