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 absorbent surface of the planar absorbent main body containing the absorber is covered with the inner surface side sheet, and leads to a penis insertion space between the absorbent surface and the inner surface side sheet at a predetermined portion of the inner surface side sheet. A circular penis insertion opening is formed (see Patent Document 1), and a portion on one side and a portion on the other side with respect to the center in the width direction of the absorption surface are covered with separate inner side sheets, respectively, 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 side sheets (see Patent Document 2). The inner sheet serves to wrap the penis and keep it damaging without leaking urine.
Such a male absorbent pad is used by being attached to the inner surface of the undergarment through an adhesive layer provided on the outer surface of the absorbent main body. At the time of urination, with the male absorbent pad attached to the underwear, as shown in FIG. 1, (a) the waist rubber 101 of the underwear 100 is pulled down, and the penis is taken out from above (b) the front opening of the underwear 100 The part 102 is widened and opened, and the penis is taken out from the opening, or (c) the front part 103 of the leg opening of the underwear 100 is widened and opened, and the penis is taken out from the opening. At this time, the underwear is expanded and contracted as indicated by arrows in FIG.

As described above, the upper end means the upper end in a state where the pad is attached to the underwear.

  As described above, according to the present invention, there are advantages such as an absorbent pad for men that can be fixed to the underwear but hardly obstructs the expansion and contraction of the underwear accompanying the insertion and removal of the genitals.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 2 shows Example 1 of a male absorbent pad according to the present invention, FIG. 3 shows a 3-3 cross section thereof, and FIG. 4 shows a 4-4 cross section thereof. The absorbent pad 1 includes a planar outer portion 10 facing the inner surface of the undergarment, and a planar inner portion 20 integrated on the body side of the outer portion 10. As long as the shape of the outer portion 10 is a plane shape, an appropriate shape can be adopted. For example, as shown in the drawing, the width becomes narrower on the lower side (in the crotch side) in consideration of fitability around the legs. It can be an inverted trapezoidal shape, a rectangular shape, or an elliptical shape. The dimensions of the outer portion 10 can be determined as appropriate, for example, the length can be about 180 to 250 mm, and the width can be about 80 to 160 mm.

  The inner part 20 forms a genital insertion space 1 s between the outer part 10 and is smaller than the outer part 10 if it has a size and shape that can cover the genital arrangement site X in the outer part 10. Or large or the same size. In the present embodiment, the genital arrangement part X (which can be determined as appropriate) is a longitudinally intermediate part and a central part in the width direction of the outer part 10, and the inner part 20 is the entire lower half of the outer part 10. The upper portion of the outer portion 10 is not covered by the inner portion 20. Moreover, the peripheral part of the inner part 20 is integrated with the body side surface of the outer part 10 except for the upper edge part. Thus, when covering the lower part of the outer part 10 with the inner part 20, the length of the inner part 20 is about 40 to 60% of the outer part 10, and the width is about 80 to 100% of the outer part 10. Is one preferred form. The opening between the upper edge of the inner portion 20 and the outer portion 10 serves as a genital insertion port into the genital insertion space 1s.

  Further, as a fixing portion for fixing the outer portion 10 to the underwear, an adhesive material layer 11 is provided over almost the entire underwear side surface (outer surface) of the outer portion 10, and a release sheet 12 is provided so as to cover the adhesive material layer 11. It is pasted. Instead of the adhesive material layer 11, a male material of a mechanical fastener or the like can be used. The arrangement and size of the adhesive material layer 11 can be determined as appropriate, but those that do not hinder the expansion and contraction of the underwear are preferable. For example, it is preferable that the adhesive layer 11 is not provided as much as possible in a portion overlapping with a portion where the underwear greatly expands and contracts. Moreover, when providing the adhesive material layer 11, it is preferable to provide the dotted | punctate and linear adhesive material layer 11 at intervals as much as possible.

  FIG. 5 shows various forms of the adhesive material layer 11. In the example of FIG. 5A, the linear adhesive material layers 11 along the width direction are provided in a plurality of rows at intervals in the longitudinal direction. The part which does not have the adhesive material layer 11 in both sides is comprised so that it may become larger in a longitudinal direction intermediate part. In this case, there is an advantage that the expansion and contraction when the front opening portion of the underwear is expanded sideways or the front portion of the leg opening of the underwear is expanded sideways is hardly obstructed. FIG. 5B is an example in which the width of the adhesive material layer 11 in FIG. 5A is extremely shortened, and a plurality of substantially dotted adhesive material layers 11 are spaced apart in the longitudinal direction along the center in the width direction. It is provided. FIG. 5C shows an example in which the distance between the adhesive material layers 11 in FIG. 5A is extremely widened, and linear adhesive material layers 11 along the width direction are provided only at both ends in the longitudinal direction. In FIG. 5D, in order to improve the stretchability in the width direction further than in FIG. 5C, the dotted adhesive layer 11 is provided on both sides of the upper end portion, and the dot shape is formed in the center in the width direction of the lower end portion. Only the adhesive material layer 11 is provided. Further, FIG. 5 (e) shows that a plurality of dot-like adhesive material layers 11 are provided only at the upper end portion with an interval in the width direction, and the expansion and contraction of the underwear in the lower part of the pad is hardly hindered. Since the adhesive material layer 11 is also provided in the upper end portion with a gap in the width direction, the expansion and contraction of the underwear is not hindered rather than simply continuing linearly.

  Characteristically, in the form shown in FIGS. 2 to 4, the absorber 30 is not provided in the entire outer portion 10, and the absorber 30 is provided only in the inner portion 20. Thereby, the rigidity of the outer part 10 to which the undergarment is fixed is suppressed to be low, and the expansion and contraction of the undergarment is hardly hindered, and the absorption performance is secured by the absorber 30 in the inner part 20. When emphasizing the absorption performance, as shown in FIG. 6, the adhesive material layer 11 is provided only on the upper portion of the outer portion 10, and the absorber 30 is not only the inner portion 20 but also the lower portion (adhesive). It is also possible to provide a portion that does not have the material layer 11. When the absorber 30 is provided in the lower portion of the outer portion 10, the size of the absorber 30 can be determined as appropriate, but the length is about 5 to 50% of the outer portion 10, and the width is 60 to 95 of the outer portion 10. One preferred form is about%.

  The cross-sectional structure will be described in more detail. The entire inner surface (body side surface) of the outer portion 10 and the entire outer surface (underwear side surface) of the inner portion 20 are formed by the liquid-permeable top sheet 31. The entire underwear side surface and the entire body side surface of the inner portion 20 are formed by a liquid-impermeable sheet 32, and the absorber 30 is interposed at a predetermined portion between the top sheet 31 and the liquid-impermeable sheet 32. Yes. The top sheet 31 and the liquid impermeable sheet 32 are preferably not fixed to the absorber 30.

As materials for these parts, known materials can be appropriately used. For example, as the liquid-permeable top sheet 31, 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 absorbent body 30, a pulp fiber stack, an aggregate of filaments such as cellulose acetate, or a non-woven fabric can be used, and a superabsorbent polymer can be mixed and fixed as necessary. . Further, as the liquid-impermeable sheet 32, a non-breathable film or a breathable porous film made of a polyethylene film or the like is used alone, or on the outer surface side (the underwear side in the outer portion and the body side in the inner portion). A laminate of various nonwoven fabrics having a basis weight of about 15 to 17 g / m ² (particularly, a laminated nonwoven fabric such as an SMS nonwoven fabric or an SMMS nonwoven fabric is preferable from the viewpoint of achieving both strength and flexibility) can be used. In particular, it is preferable to use a material having a high elasticity such as a stretchable polysheet as the material for the outer portion 10 because the expansion and contraction of the underwear at the fixed portion by the adhesive 11 is hardly inhibited.

  Further, as shown in FIGS. 7 and 8, a plurality of slits 32s extending in the vertical direction are formed at intervals in the width direction on at least the upper end portion of the underwear side in the outer portion 10, that is, the liquid-impermeable sheet 32. At the same time, it is also preferable to attach a liquid-impermeable stretchable sheet 13 such as a separate urethane sheet to the underwear side surface of the portion having the slit 32s, and to provide the adhesive material layer 11 on the underwear side surface (outer surface). In this case, opening and closing of the slit 32 s causes the upper end portion of the liquid impermeable sheet 32 to expand and contract significantly, and liquid leakage through the slit 32 s is blocked by the liquid impermeable elastic sheet 13. In particular, as shown in the drawing, a plurality of rows of slits 32s arranged in the width direction are provided at intervals in the longitudinal direction, and the longitudinal direction range of the slits 32s in each row is the longitudinal direction of the slits 32s in the adjacent row. It is preferable that the slits 32s in each row are alternately arranged so as to partially overlap the range.

  On the other hand, in the cross-sectional structure as described above, for example, the absorber 30 is sandwiched between the liquid-permeable top sheet 31 and the liquid-impermeable back sheet 32, and the top sheet 31 and the liquid-impermeable sheet 32 are hot at the peripheral portion. After a laminated structure is formed by bonding with a melt adhesive, heat seal, ultrasonic seal, or the like, the side surface of the top sheet 31 is overlapped with one side of the laminated structure as an inner portion 20 and the other side as an outer portion 10. In this way, the side edges E and E in the width direction of the top sheet 31 of the inner part 20 are joined to the top sheet 31 of the outer part 10 by hot melt adhesive, heat sealing, ultrasonic sealing or the like. be able to. In this case, the configuration shown in FIGS. 2 to 4 is obtained by providing the absorbent body 30 only on the inner portion 20, and the configuration shown in FIG. 6 is extended from the inner portion 20 to the outer portion 10 through the folded portion. It becomes. In these forms, the top sheet 31 and the back sheet 32, and in the form of FIG. 6, even the absorber 30 can be formed of an integral material continuous from the outer part 10 to the inner part 20. That is, since the outer portion 10 and the inner portion 20 are seamlessly continuous at the lower end portion (mounted state) of the genital insertion space 1s, there are advantages such as excellent absorption performance and no fear of urine bleeding.

  Further, as shown in FIG. 9, after the outer portion 10 and the inner portion 20 are separately formed by the separate top sheet 31, back sheet 32, and absorber 30, the inner portion 20 is formed on the body side of the outer portion 10. Can also be integrated. In this case, each of the outer portion 10 and the inner portion 20 is formed by joining a top sheet and a liquid-impermeable sheet at the peripheral edge by a hot melt adhesive, heat sealing, ultrasonic sealing, or the like. When the outer portion 10 and the inner portion 20 are integrated, the peripheral portion of the inner portion 20 in the top sheet 31 is hot-melt adhesive or heat sealed with respect to the top sheet 31 of the outer portion 10 except for the upper edge portion. Bonded by ultrasonic sealing or the like. The form shown in FIG. 9 is a form in which the absorber 30 is not provided between the top sheet 31 and the back sheet 32 in the outer part 10, but the lower part of the outer part 10 follows the form shown in FIG. 6. An absorber can also be provided between the top sheet 31 and the back sheet 32 in the portion. With such a configuration, it is possible to select a material having a good touch for each of the outer top sheet and the inner top sheet. In addition, it is possible to select a material that does not obstruct expansion and contraction of the underwear with respect to the outer back sheet, and a material that has a good touch with respect to the inner back sheet.
