Description

  The present invention relates to a male absorbent pad.

As an absorbent article for dealing with urine leakage of adult males, male absorbent pads have been proposed and are commercially available. Specifically, the entire absorption surface of the planar absorption main body portion that absorbs urine is covered with an inner surface side sheet, and a circular shape that leads to a penis insertion space between the absorption surface and the inner surface side sheet at a predetermined portion of the inner surface side sheet. A penis insertion opening (see Patent Document 1), and a part on one side and a part on the other side with respect to the center in the width direction of the absorption surface are respectively covered with separate inner side sheets, There has been known one in which a penis is inserted into a penis insertion space between an absorbing surface and an inner surface side sheet from a slit-like opening between sheets (see Patent Document 2).
Such a male absorbent pad is used by being attached to the inner surface of the pants. The inner sheet serves to wrap the penis and keep it damaging without leaking urine.

  As described above, according to the present invention, there are advantages such as easy removal of the penis in the lateral direction and easy insertion of the penis from the lateral direction.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows Example 1 of a male absorbent pad according to the present invention, and FIG. 2 shows a 2-2 cross section thereof. The absorption pad 1 includes a planar absorption main body 10 having an absorption surface that absorbs urine, and an inner surface side sheet 20 that covers the absorption surface. The absorption main body 10 has a shape in which the right side bulges outward in the width direction with respect to the lower side (crotch side) of the absorption main body 10 based on a rectangle. The shape of the absorbent main body 10 is not limited to this, and an appropriate shape can be adopted as long as it is planar. For example, it is rectangular as shown in FIG. As shown in FIG. 5, it is possible to form an inverted trapezoidal shape whose width is narrower toward the lower side (the crotch side). The example of FIG. 5 is basically the same as the example of FIG. 4 except for the shape. Furthermore, as shown in FIG. 6, a recess 19 that is recessed inward in the width direction can be formed in accordance with the opening edge 31 </ b> E on the outer surface side of the front opening 31 of the underwear 30. In this case, the hand and the penis can be easily put in and out of the inner surface side of the absorbent pad 1 through the front opening 31. The example of FIG. 6 is basically the same as the example of FIG. The dimensions of the absorbent main body 10 can be appropriately determined. For example, the length can be about 180 to 250 mm, and the width can be about 80 to 160 mm.

  As shown in FIG. 2, the structure of the absorbent main body 10 includes a liquid-permeable top sheet 11 located on the skin side, a liquid-impermeable sheet 14 located on the outer surface side, and an absorption interposed therebetween. And a body 13. The top sheet 11 and the liquid-impermeable sheet 14 are bonded to each other at the peripheral edge portion 10E by a hot melt adhesive, heat seal, ultrasonic seal or the like, and the absorber 13 is accommodated in a space surrounded by the bonded portion.

  Further, in the illustrated form, an intermediate sheet 12 is interposed between the top sheet 11 and the absorber 13, and an exterior sheet 15 that forms the outer surface of the product is attached to the outer surface of the liquid-impermeable sheet 14, An adhesive material layer 16 for fixing the product to the pants is provided on the outer surface of the exterior sheet 15, and a release sheet 17 is attached so as to cover the adhesive material layer 16. Among these components, the intermediate sheet 12, the exterior sheet 15, the adhesive material layer 16, and the release sheet 17 can be omitted as necessary.

As materials for these parts, known materials can be appropriately used. For example, as the liquid-permeable top sheet 11, in addition to various nonwoven fabrics having a basis weight of about 17 to 21 g / m ² , a perforated film having a large number of holes can be used. As the liquid-impermeable sheet 14, polyethylene is used. A non-breathable film made of a film or the like or a breathable porous film can be used. Further, as the absorbent body 13, a pulp fiber stack, an aggregate of filaments such as cellulose acetate, or a non-woven fabric is used, and a superabsorbent polymer is mixed and fixed as necessary. Can do. The intermediate sheet 12 has a function of quickly transferring the absorbent liquid to the absorbent body 13 and a function of preventing the reverse from the absorbent body 13, and as the material, various nonwoven fabrics having a basis weight of about 17 to 40 g / m ^2. In particular, an air-through nonwoven fabric and a spunbond nonwoven fabric can be suitably used. The exterior sheet 15 has a function of reducing the touch and frictional sound on the outer surface of the product, and the material thereof is various nonwoven fabrics having a basis weight of about 15 to 17 g / m ² , particularly from the viewpoint of both strength and flexibility. Laminated nonwoven fabrics such as nonwoven fabrics and SMMS nonwoven fabrics can be suitably used.

  On the surface (absorbing surface) of the top sheet 11 of the absorbent main body 10, an upper edge 21 that obliquely crosses the penis arrangement site X and is not joined to the surface of the top sheet 11, and both the left and right sides and the lower side of the penis arrangement site X And a non-joined portion that is surrounded by the upper edge 21 and the lower peripheral edge portion 22 and is not joined to the surface of the top sheet 11 ( That is, an inner surface side sheet 20 having a free portion 23 is provided.

  More specifically, the penis arrangement portion X in the present example is an intermediate portion in the longitudinal direction and an intermediate portion in the width direction in the absorption main body portion 10, but this portion can be appropriately changed in design. The upper edge 21 of the inner surface side sheet 20 extends from the upper edge 10u at one side (right side toward the surface of the top sheet 11 in the example of FIG. 1) on the other side (in the example of FIG. 1). It extends linearly to the lower side of the center in the longitudinal direction of the side edge 10s on the left side) toward the top sheet 11 surface. The portion below the upper edge 21 of the inner surface side sheet 20 extends to both side edges and the lower edge of the top sheet, and the hatched lower peripheral edge portion 22 is joined to the surface of the top sheet 11. A penis insertion space is formed between the joint portion 23 and the top sheet 11 surface. Further, along the upper edge 21 of the inner surface side sheet 20, an elongated elastic elastic member 25 is fixed in an extended state over substantially the whole (or a part such as an intermediate portion).

  On the other hand, the surface of the top sheet 11 is exposed on the upper side of the upper edge 21 of the inner surface side sheet 20 without providing another inner surface side sheet, and the upper edge 21 of the inner surface side sheet 20 and the surface of the top sheet 11 are exposed. The space between the two becomes an opening for inserting the penis into the penis insertion space (between the non-joined portion 23 of the inner sheet 20 and the surface of the top sheet 11).

  In the male absorbent pad 1 thus configured, the penis inserted into the penis insertion space can be taken out from the diagonally upward opening in the lateral direction (left side in the example of FIG. 1), and the penis is attached to the inner surface side sheet 20. It is difficult to catch and easy to take out. Further, even when penis is inserted, it can be easily inserted by sliding the penis from the lateral direction with respect to the opening facing diagonally upward. Further, as shown in FIG. 3, the upper edge 21 of the inner surface side sheet 20 contracts along the extending direction due to the expansion / contraction force of the elongated elastic expansion / contraction member 25, and the absorption main body 10 is reduced by the contraction. The surface of the top sheet 11 is deformed so as to be depressed, and the inner side sheet 20 and the surface of the top sheet 11 are separated to form a penis insertion space S. Therefore, it becomes easier to put in and out the penis. In addition, the absorbent main body 10 has a three-dimensional shape that wraps around the penis, so that the fit to the penis is improved and the presence of the absorbent pad 1 hardly appears on the outer surface of the clothing.

As a material of the inner surface side sheet 20, various nonwoven fabrics having a weight per unit area of 15 to 20 g / m ² , a liquid impervious film such as polyethylene, and a material obtained by bonding the liquid impervious film and the nonwoven fabric together. Etc. can be used. The liquid-impermeable film is preferably a breathable porous film, but may be a non-breathable film.

  As the elongated elastic elastic member 25, natural or synthetic rubber formed in a thread shape, a string shape, or a belt shape can be suitably used.

  The shape of the inner surface side sheet 20 is not particularly limited. For example, as shown in FIGS. 4 to 6, the direction of the upper edge 21 of the inner surface side sheet 20 may be reversed left and right with respect to the configuration of FIG. 1. Various forms as shown in FIG. 7 can also be adopted. That is, as shown in FIG. 7 (a), the upper edge 21 of the inner surface side sheet 20 may have the upper end 21u positioned at the corner between the upper edge and the side edge of the absorbent main body 10, As shown in FIG. 7 (b), the lower end 21b may be positioned at the corner between the lower edge 10b and the side edge of the absorbent main body 10, and as shown in FIG. 7 (c), The lower end portion 21 b may be positioned on the lower edge 10 b of the absorption main body portion 10.

  Further, as shown in FIG. 7D, in the portion below the upper edge 21 of the inner surface side sheet 20, the entire surface of the top sheet 11 is not covered with the inner surface side sheet 20, and a part 11e is exposed. May be. Moreover, as shown in FIG.7 (e), the upper edge 21 of the inner surface side sheet | seat 20 may be curvilinear, and although not shown in figure, it may be the bending line | wire shape which bends in an intermediate part.

  On the other hand, the male absorbent pad according to the present invention can be manufactured, for example, as follows. That is, after the liquid impermeable sheet 14, the absorber 13, the top sheet 11 and the like are laminated in advance and cut into a predetermined shape to produce the absorbent main body 10 (not shown), the absorbent main body 10 is As shown in FIG. 8 (a), the longitudinal direction 10L is sequentially supplied and conveyed on the line so that the longitudinal direction 10L is inclined with respect to the MD direction (transfer direction). On the other hand, the belt-shaped inner surface side sheet 20 is continuously supplied and fixed so that the longitudinal direction 20L thereof is along the MD direction, and then the continuous inner surface side sheet 20 is superposed at a predetermined interval in the MD direction. It is possible to manufacture an individual absorbent pad for men by cutting including the.

  In this case, as shown in FIG. 8B, the two absorption main body portions 10 and 10 are shifted in phase with respect to one line in the CD direction (direction orthogonal to the MD direction), and 2 By making two absorption main body portions 10 and 10 close to each other so as to be point-symmetric, it is possible to take two pieces with a narrower line width.
