The male urine absorbent article 1 according to the present embodiment is an auxiliary absorption that is attached to the wearer's penis 2 and absorbs urine inside an outer (exterior article such as a disposable diaper or pants) worn by the wearer. It is a tool. In the following description, for convenience of explanation, the top sheet 31 side is “upper” or “front”, and the backsheet 32 side is “lower” or “back”.

  The configuration of the male urine absorbent article 1 will be described with reference to FIGS. 1 and 2. FIG. 1 is a plan view illustrating a configuration of a male urine absorbent article 1 in a natural state (unused state) according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG. It is sectional drawing which cut | disconnected the male urine absorption article 1 by the surface perpendicular | vertical to the up-down direction. The male urine absorbent article 1 according to the present invention is a male urine absorbent article having a dimension P in the longitudinal direction larger than a dimension Q in the width direction perpendicular to the longitudinal direction. In the urine absorbent article 1 for men, the substantially sheet-like laminate 3 and the top sheet 4 are joined to each other at their outer peripheral edges by a hot melt adhesive or the like (the joined part is indicated as a joined part S in the figure). The bag-shaped auxiliary absorbent is configured to store the penis inserted through the opening 5 formed in the top sheet 4 in the internal space 7 a in the bag body 7. In the cross-sectional view of the male urine absorbent article 1 including FIG. 2, for convenience of explanation, the laminated body 3 and the internal space 7 a are illustrated as being expanded in the vertical direction, but in actuality, they are thin in the vertical direction.

<1. Laminate>
The laminate 3 includes a substantially sheet-like absorber 33 that absorbs and holds urine discharged from the penis, a liquid-permeable top sheet 31 that covers the upper surface of the absorber 33, and a liquid impermeable material that covers the lower surface of the absorber. And a permeable (including poorly permeable) back sheet 32. The top sheet 31 and the back sheet 32 are joined to each other around the absorbent body 33 by a hot melt adhesive. The top sheet 31 and the back sheet 32 may be joined (the joining portion is indicated as a joining portion T in the drawing) by a method such as thermal joining or ultrasonic sealing. For hot melt adhesives, select from hot melt adhesives such as rubber, polyolefin, vinyl acetate, etc., direct coater coating, indirect spiral coating, melt blow (curtain spray) coating, bead coating. Apply by the method.

  The top sheet 31 is a sheet that constitutes the upper surface of the laminate 3, and is a liquid-permeable sheet that opposes a surface sheet 4 to be described later via a space 7a. The space 7a is a space that constitutes the inside of the bag body 7 of the male urine absorbent article 1, and is a space in which the inserted penis 2 can be stored.

  As the top sheet 31, in order to directly touch the skin of the wearer (penis), a sanitary material suitable for this is selected in consideration of a good touch without damaging the skin more than necessary. A liquid-permeable sheet suitable for quickly capturing the urine and allowing the urine to quickly permeate the absorber 33 is used. For example, a nonwoven fabric using hydrophilic fibers such as cellulose, rayon and cotton is preferable. In addition, as the top sheet, it is also possible to use a non-woven fabric which is made liquid-permeable by treating the surface of hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, nylon and the like with a surfactant.

  The back sheet 32 is a sheet constituting the lower surface of the laminated body 3, and prevents urine that has passed through the top sheet 31 and urine that has been absorbed by the absorber 33 from exuding from the inside of the absorber 33 to the outside. It is a liquid-impermeable sheet. From the viewpoint of wearability, the surface area of the back sheet 32 is desirably the same as that of the top sheet 31.

  As the back sheet 32, a liquid-impermeable sheet made of a sanitary material is generally used. For example, a water-repellent nonwoven fabric using hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon is used. A water-repellent or liquid-impervious plastic film, a composite material of the nonwoven fabric and the plastic film, or the like may be used as the back sheet 32. In this case, from the viewpoint of the wearer's comfort, it is preferable to use a plastic film that has moisture permeability (that is, breathability), can permeate water vapor to prevent stuffiness, and has some flexibility. .

  The absorber 33 plays a role of absorbing and holding urine that has passed through the top sheet 31. Therefore, any material having excellent liquid absorbability can be used. As such an absorbent 33, a granular water-absorbing property is formed on an aggregate of hydrophilic fibers (for example, pulverized pulp fibers or cellulose fibers). It is formed by wrapping a mixture of polymers with a covering sheet such as tissue paper or a liquid-permeable nonwoven fabric, and absorbs urine that has passed through the top sheet 31 to quickly hold and fix it. The cover sheet that wraps the hydrophilic fiber is bonded to the hydrophilic fiber and the water-absorbing polymer with a hot-melt adhesive to prevent the hydrophilic fiber from losing its shape and the water-absorbing polymer from falling off (especially after water absorption). To do. Also, it is possible to use a substantially sheet-shaped absorbent body in which an adhesive or the like is applied to the opposing surfaces of two liquid-permeable sheets facing each other substantially in parallel, and a layered absorbent polymer (polymer layer) is sandwiched and fixed. it can. In this case, the polymer layer is a substantially rectangular layer extending in the longitudinal direction, and a plurality of polymer layers are arranged at intervals in the width direction. In the non-existing region of the polymer layer, the two liquid-permeable sheets are joined and sealed.

<2. Surface sheet>
The top sheet 4 has an opening 5 for inserting a penis. As the topsheet 4, when the wearer wears the male urine absorbent article 1, the top surface 4a of the topsheet 4 comes into contact with the wearer's lower abdomen 40, crotch and thigh 41 (see FIG. 8). That is, since the skin of the wearer is touched, it is desirable to use a flexible and liquid-impermeable sheet made of a sanitary material with a good touch feeling in consideration of a comfortable wearing feeling. For example, a water-repellent nonwoven fabric using hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon is used. A water-repellent or liquid-impervious plastic film, a composite material of the nonwoven fabric and the plastic film, or the like may be used as the top sheet 4. In this case, from the viewpoint of the wearer's comfort, it is preferable to use a plastic film that has moisture permeability (that is, breathability), can permeate water vapor to prevent stuffiness, and has some flexibility. . It is also possible to use water-repellent nonwoven materials such as spunbond nonwoven fabric, melt blown nonwoven fabric, and SMS nonwoven fabric.

<3. Folding part>
Next, a configuration for bending the male urine absorbent article 1 will be described with reference to FIGS. 1 to 3. FIG. 3 is a cross-sectional view of the male urine absorbent article when bent through the bent portion 10. The laminated body 3 is provided with a bent portion 10 extending in the width direction in the vicinity of the central region in the longitudinal direction of the laminated body 3. The bent portion 10 is a portion of the laminate that can bend the laminate 3 along the virtual bending axis O extending in the width direction in the vicinity of the central region in the longitudinal direction of the laminate 3. By folding the laminate 3 (and thus the urine absorbent article 1 for men) into a mountain fold along the portion 10, as shown in FIG. 3, the back sheet 32 can be folded in half. . In addition, when the male urine absorbent article 1 is folded in two with the folded portion 10 extending in the width direction as a center, the space 7a for storing the penis 2 is shown in FIG. 3 from the flat natural state of FIG. Is divided into two via the virtual bending axis O. At this time, the bag body which has the space divided into two is set as the 1st bag body 71 and the 2nd bag body 72, respectively. Therefore, when the male urine absorbent article 1 is attached, the male urine absorbent article 1 is folded in two along the bent portion 10, and the penis 2 is opened in the space in the first bag body 71 through the opening 5. 71a or the space 72a of the second bag body 72 can be selectively stored.

  Moreover, the male urine absorbent article 1 according to the present embodiment includes a bending guide portion 101 that concentrates bending stress on a portion corresponding to the bending portion 10 of the laminate 3 as shown in FIGS. 1 and 2. ing.

Specifically, a bending guide portion 101 in which bending stress is concentrated on the bending portion 10 is provided by forming a structurally weak region in the bending portion 10 extending in the width direction. The bending guide unit 101 according to the present embodiment is realized in various forms, for example, by slitting or embossing the stacked body 3 or the absorber 33 at a position corresponding to the bending unit 10. With such a configuration, the stacked body 3 can be easily bent and the bent state can be maintained stably and continuously. That is, since the bending portion 10 is structurally weak, the restoring force for returning from the bent state to the original natural state (substantially flat plate state) is weak, so that the shape retention of the bent state is improved. be able to. In addition, by providing the bending guide part 101, it is easy to visually recognize where to be bent, and it is easy to install / make it easy to attach.

  In addition, in the laminate 3, the absorber 33 is shifted from the region where the absorber 33 exists for some reason into the region where the absorber is missing, and the bending stress concentrated on the bent portion 10 is dispersed. In order to avoid this, it is desirable that the top sheet 31 and the back sheet 32 in the region where the absorber 33 is removed are joined in the vertical direction by a hot melt adhesive or the like (in FIG. It is indicated as a joint U).

  Further, the shape of the male urine absorbent article 1 can be substantially constant (for example, a rectangular shape in plan view) over almost the entire length in the longitudinal direction, but the following shape is desirable. Specifically, the length in the width direction of at least one of the first bag body 71 or the second bag body 72 of the male urine absorbent article 1 (the width direction of the laminate 3 and the top sheet 4 constituting the bag body). Is configured to gradually narrow from the bent portion 10 extending in the width direction toward one side in the longitudinal direction. In the present embodiment, the length in the width direction of the first bag body 71 (the length in the width direction of the laminated body 3 and the top sheet 4 constituting the first bag body 71) is one side in the longitudinal direction from the bent portion 10. It gradually narrows toward At this time, the shape of the first bag 71 is substantially trapezoidal in plan view as shown in FIG. This shape is in contact with the wearer's crotch and the inner surface of the thigh 41, and the male urine absorbent article 1 is easy to fit into the wearer's body shape. For this reason, the portion of the male urine absorbent article 1 to be applied to the crotch and thigh 41, that is, the first bag body 71 is formed in a substantially trapezoidal shape, so that The penis 2 is inserted and housed in the internal space 71a, the first bag 71 is placed against the wearer's crotch and thigh 41, and the second bag 72 is placed against the wearer's abdomen 40. When the urine absorbent article 1 is worn, it fits the wearer's crotch and thigh 41 and does not give the wearer a sense of incongruity and does not hinder the movement of the wearer's foot in the worn state. An effect can be obtained.

  The shape of the male urine absorbent article 1 may be within a range in which the above-described effects can be obtained and the extent that the absorption area of the absorbent body 33 in the first bag 71 is sufficiently secured. For example, in the above embodiment, the shape of the first bag body 71 applied to the wearer's crotch portion is a substantially trapezoidal shape in plan view, but may be a substantially triangular shape, a substantially elliptical shape, or the like.
