DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a male urine absorbing pad which is used by male bedridden persons or incontinent persons in combination with a disposable diaper or through underwear.
More specifically, the present invention relates to a male urine absorption pad that has a high leakage prevention effect and is easy to wear.

[0002]

2. Description of the Related Art An example of a conventional urine-absorbing pad used by male bedridden persons or incontinent persons is Japanese Utility Model Application Laid-Open No. 2-6.
No. 024, JP-A-9-173370 and the like. A liquid-permeable top sheet, a liquid-impermeable back sheet, and a rectangle composed of an absorber disposed between these two sheets, and the back sheet is coated with an adhesive for forming a funnel shape. ing. When using for men,
One end of the end flap portion of the urine absorbing pad is bent toward the top sheet, and the other end flap portion is further folded over the back sheet at one end, and bonded to the adhesive applied to the back sheet to form a funnel. Formed and used to wrap the male genitalia.

[0003] As one example of this type of urine collecting pad for men, Japanese Utility Model Publication No. 61-30653 discloses a urination bag for men. The disclosed urination bag has a liquid-permeable front inner sheet, a liquid-impermeable outer sheet, and two pads composed of an absorber disposed between these two sheets, and the periphery of the pad is sealed. It is shaped like a bag. One of the stacked pads has an opening for inserting a male genitalia into the bag.

A urine pad for men disclosed in Japanese Patent Application Laid-Open No. 10-234765 is composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between these two sheets. Adhesive is applied to the longitudinal side edge, and in order to insert the male genitalia, it starts with a circular hole penetrating the thickness direction on one of the pads or one end flap part of the pad A substantially U-shaped notch toward the other end flap, or a U-shaped notch beginning at one side edge and extending toward the other side edge. . When used, it is folded along a straight line perpendicular to the longitudinal direction at a required portion in the longitudinal direction and overlapped, and is formed into a bag shape by bonding with an adhesive material, and the male genital is the circular hole,
Alternatively, it is disclosed to insert and use from a U-shaped notch.

[0005]

SUMMARY OF THE INVENTION
No. 4, JP-A-9-173370, and the like, the male urine absorbing pad is formed in a funnel shape, so that it is effective when the urination volume is small, but is effective when the urination volume increases. Urine leaks from the lower end. Also, if the funnel could not be formed well, there would be a gap at the bottom of the funnel,
Urine leaks out even when urination is low. In addition, the shape of the male genital root is widened, it is not stable when worn, and easily falls off. In some cases, an adhesive is applied to the back sheet to prevent falling off, but this is not very effective.

[0006] The urination bag known from Japanese Utility Model Publication No. 61-30653 has to be inserted so that the male genitalia is pushed from the outside to the inside of the bag, so that the urination bag may not be fitted smoothly. Especially in the case of elderly people, insertion becomes difficult. Although it is possible to make the opening large and easy to attach, it is easy to fall off.

[0007] The male urine absorption pad disclosed in Japanese Patent Application Laid-Open No. H10-234765 has a male genital insertion portion having a circular hole.
It is relatively easy for the person to wear it while standing, but it is very difficult for the caregiver to wear it, and even if it is done, it takes time. When the insertion opening is U-shaped, mounting is easier than that of a circular shape, but it is not stable at the time of mounting and easily falls off.

Accordingly, an object of the present invention is to overcome the problems of the above-mentioned conventional products, and when used together with a diaper, or when worn via underwear, has a high urine leakage preventing effect and is easy to wear. It is to provide a sometimes stable urine collection pad for men.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a male urine absorbing pad having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between these sheets. A water-repellent cover sheet is disposed on the top sheet, and the cover sheet has an elongated opening formed in the center in the longitudinal direction of the cover sheet, and
The peripheral edge of the outer periphery is joined to the topsheet, and furthermore, elastic members are arranged in an extended state on both side edges along the longitudinal direction of the coversheet opening, whereby the coversheet around the opening is exposed to the surface. A male urine absorption pad characterized by being separated from a sheet and having the opening serving as a male genital insertion port.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the male urine absorbing pad of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these embodiments. FIG. 1 is a perspective view of a male urine absorbing pad of the present invention. FIG. 2 is a sectional view taken along line XX ′ of FIG. 1 and 2, the male urine absorbing pad is basically composed of a liquid-permeable top sheet 1, a liquid-impermeable back sheet 2, and an absorber 3 disposed between these two sheets. Further, a water-repellent cover sheet 6 is arranged on the liquid-permeable top sheet 1, and an opening 4 for inserting a male organ is formed in the center of the cover sheet 6, which is elongated in the longitudinal direction. The elastic members 5 are arranged in an extended state on both side edges along the longitudinal direction of the opening 4. In addition, cover sheet 6
Is joined to the topsheet 1.

The topsheet used in the present invention is:
Hydrophilic non-woven fabric, woven fabric, porous plastic film, etc., whose constituent fibers are monofilaments such as polypropylene, polyethylene, polyester and nylon, or composite fibers composed of two or more components such as polyester, polypropylene, polyethylene and nylon And the like, in particular, polyester / polyester, polyester / polyethylene,
Polypropylene / polyethylene composite fibers are preferred in terms of strength, but are not particularly limited.

The back sheet used in the present invention comprises:
A liquid impermeable film such as polyethylene, a material in which a liquid impermeable film is bonded to a nonwoven fabric or a woven fabric, or the like. More preferably, in order to prevent stuffiness, a polyethylene film provided with a large number of micropores that do not allow liquid to permeate, a moisture-permeable film stretched by adding a filler to a thermoplastic resin, or a film of these films When using a composite sheet with a nonwoven fabric and a woven fabric attached to the outside,
Since excess water in the pad is released to the outside of the pad in a gaseous state, stuffiness and rash are less likely to occur, and moisture permeability and feel can be made comfortable.

The absorbent used in the present invention comprises cotton-like pulp, superabsorbent polymer (hereinafter abbreviated as SAP), hydrophilic sheet and the like, and is not particularly limited. Further, the absorber used in the present invention,
It is made from known absorbent materials commonly used in conventional male urine absorption pads and other absorbent articles. That is, absorbent fibers such as floc pulp and rayon and SAP
May be used. A single-layer or multi-layer mat obtained by mixing the above-mentioned materials, a material in which SAPs are uniformly arranged between layers of a mat made of absorbent fiber, and the like formed by wrapping with a hydrophilic sheet can be used. Further, if necessary, 3 to 60% by weight of a heat-fusible substance may be mixed with the cotton-like pulp and thermocompression-bonded. Alternatively, only the SAP may be wrapped by the hydrophilic sheet.

As the cotton-like pulp, a chemical pulp sheet or a pulp sheet obtained by defibrating a mechanical pulp sheet with a crusher and having a fiber length of 5 mm or less is used. The pulp raw material is not limited to softwoods, but hardwoods, straws, bamboos, and kenafs are also applicable. Also, used paper pulp may be used. The amount of the cotton-like pulp used varies depending on the intended absorber, for example, depending on whether it is used alone, a plurality of layers are used, or another absorbent is used in combination. 400 g / m ² .

[0015] Examples of SAP include starch, cellulose and synthetic polymer. That is, starch-acrylic acid (salt) graft copolymer, saponified starch-ethyl acrylate graft copolymer, starch-
Saponified product of methyl methacrylate graft copolymer, starch-acrylonitrile graft copolymer, saponified starch-acrylamide graft copolymer,
Acrylic acid (salt) polymer, polyethylene oxide cross-linked with acrylic acid, cross-linked product of sodium carboxymethyl cellulose, cross-linked product of polyvinyl alcohol-maleic anhydride reactant, etc. can be used.
It absorbs urine, body fluid and water more than 20 times its own weight,
Sodium polyacrylate is most suitable from the viewpoint of absorption performance. The amount of the SAP used is 10 to 500 parts by weight, preferably 15 to 300 parts by weight, based on 100 parts by weight of the dried floc pulp, and such an amount of the SAP is substantially uniformly distributed in the floc pulp. When SAP absorbs and swells urine and bodily fluids, the particles have minimal interference with each other and are less likely to form a permeation barrier by continuous contact. Transmits and absorbs quickly in the direction.

The hydrophilic sheet may be any hydrophilic sheet such as a tissue, an absorbent paper, a hydrophilic nonwoven fabric, or the like. As a method of compressing the absorber, the absorber may be compressed into a continuous surface by a roll or the like having a smooth peripheral surface so that the density of the absorber becomes substantially uniform over the entire surface, or the peripheral surface may be formed in an uneven shape. The density of the absorber may be partially different depending on the roll or the like, and the absorbent may be compressed so as to be embossed in a pattern arrangement for guiding urine and body fluid in the vertical and oblique directions. In the case of embossing, the compression section and the non-compression section may be continuous or discontinuous.

The shape of the absorber is not particularly limited, as long as it is a known shape generally used in conventional urine absorbing pads for men and other absorbent articles. Further, a diffusion layer may be provided on at least a part of the absorber. By providing the diffusion layer, even when the space under the top sheet is not sufficiently provided due to the posture of the wearer or the like, it is possible to prevent leakage of urine, body fluid, and the like without reducing the absorption rate of urine, body fluid, and the like. It becomes possible.

The diffusion layer is a hydrophilic liquid-permeable nonwoven fabric, woven fabric, cotton-like pulp, or the like, and its component may be polypropylene, polyethylene, polyester, rayon, pulp, or a composite fiber thereof. It is not what you receive. The diffusion layer is provided between the topsheet and the absorber, and is fixed to the absorber with an adhesive or the like.

The water-repellent cover sheet used in the present invention may be a non-woven fabric, a woven fabric, a liquid impermeable film such as polyethylene, a material in which a liquid impermeable film is bonded to a non-woven fabric or a woven fabric, or the like. When using a liquid-impermeable film, a polyethylene film with a large number of micropores that do not allow liquid molecules to pass through to prevent stuffiness, or a moisture-permeable film that has been stretched by adding a filler to a thermoplastic resin Films are preferred. When a non-woven fabric or a woven fabric is used, its constituent fibers are monofilaments such as polypropylene, polyethylene, polyester, and nylon, or composite fibers composed of two or more components such as polyester, polypropylene, polyethylene, and nylon. Polyester / polyester, polyester / polyethylene, and polypropylene / polyethylene composite fibers are preferred from the viewpoint of strength, but are not particularly limited.

The elastic members provided on both side edges of the opening portion of the water-repellent cover sheet are thread-shaped, string-shaped, net-shaped, and flat-shaped ordinary urine-absorbing pads for men, such as natural, synthetic rubber, and urethane. Stretchable elastic bodies used in absorbent articles can be used. The number of elastic members used may be one or more. The elastic body is placed in the stretched state and can be hot melt, starch based or CMC
The adhesive is fixed to the water-repellent material by a water-soluble glue such as (carboxymethylcellulose), a highly fluid adhesive, or welding by heat or ultrasonic waves.

The topsheet and the water-repellent coversheet have a hot-melt, starch-based or C
The bonding is performed by a water-soluble glue such as MC (carboxymethyl cellulose), a highly fluid adhesive, or welding by heat or ultrasonic waves.
