Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a diaper cover for an absorbent pad.

[Background of the invention]

As a well-known diaper cover for diapers or smoke-absorbing pads, waterproof cloth diaper covers are commercially available, but these are not expensive and are not suitable for children. There are problems such as the need to replace them as the product grows.

In addition, disposable diaper covers made of synthetic resin film are used in Europe and other countries (for example, Japanese Patent Application Laid-Open No. 51-19645). There was a problem.

On the other hand, recently, paper diapers that do not require a diaper cover (a diaper and a diaper are integrated) have come into use. It is made up of a permeable nose sheet and an absorbent material in between (fluff pulp, tissue, polymeric material, etc., which is dangerous because it absorbs water), and the whole thing has to be thrown away every time a diaper is changed, which increases costs. This is a big problem not only in terms of storage, but also in terms of disposal.In addition, disposable diapers that are integrated with pants are bulky and require improvement in terms of portability.

[Purpose of the invention]

The purpose of the present invention is to solve the problems of conventional diaper covers as described above or disposable disposable diapers that combine diapers and pants, and to provide a disposable diaper cover for absorbent pads that is inexpensive and easy to wear. It is to provide fr.

[Structure of the invention]

The present invention is a diaper cover for an absorbent pad made of a liquid-impermeable sheet selected from a synthetic resin film such as polyethylene or polypropylene, or a sheet made of nonwoven fabric or paper laminated with a synthetic resin such as polyethylene. Foamed urethane film in the longitudinal direction of the surface,
When attaching an elastic member such as urethane rubber film, rubber thread, or elastic synthetic resin film, the entire surface of the liquid-impermeable sheet containing the elastic member must be covered with a surface sheet made of non-woven fabric. This is a diaper cover for absorbent pads that is characterized by a significantly improved fit in the crotch area, and the effect of preventing urine leakage. By attaching an elastic member made of the same material as above to the center of the upper side,
It is also possible to further improve the fit.

The elastic member, the liquid-impermeable sheet, and the top sheet may be bonded together by any bonding means such as hot-melt bonding or heat-sealing bonding that is used in ordinary diapers.

The diaper cover for the absorbent pad of the present invention is much cheaper than conventional cloth diaper covers and can be used as a disposable diaper. However, from the viewpoint of resource conservation, it is desirable to use it several times.

In other words, it is different from the conventional pants and paper diapers that come in one package, and the diaper cover can be used several times by replacing only the pads, so it is not a fool's errand, it saves resources. It also brings about desirable effects from the viewpoint of waste disposal and other aspects. Furthermore, compared to conventional disposable diapers, they can be made much more compact, making them much more convenient to carry. Furthermore, the elastic member attached to the crotch area improves the adhesion to the crotch, so compared to the European type diaper cover with a synthetic resin film surface, it is greatly improved in terms of adhesion and appearance. Since the surface that touches the skin is made of non-woven fabric, it feels good on the skin and absorbs moisture, making it less prone to dry spots and stuffiness compared to film. Of course, it can be used in exactly the same way as commercially available disposable diapers that are integrated with pants.

Embodiments of the present invention will be described below based on the drawings.

FIGS. 1, 2, and 5 are partially cutaway exploded views of the diaper cover of the present invention, and are perspective views showing the state in which the diaper cover No. 41 (shown in factor 1) is attached. Furthermore, FIGS. 5, 6, and 7 are cross-sectional views taken along the line x-x' of the general lower part of the diaper cover shown in FIGS. 1 to 3.

In the drawings, 1 is a liquid-impermeable sheet, 2 is the front side of the diaper cover, 5 is the inseam area, 4 is the torso area, 5 is the thigh area, 6 is the body area, 7 is the length, and 8 is the body area. Mounting tape, 9
．． 10 is a stretchable elastic member, 11 is an adhesive portion, 12 is a nonwoven fabric, 13 is a nonwoven fabric layer of a laminate sheet, and 14 is a film layer of a laminate sheet.

Diaper cover〇As the material for the liquid-impermeable sheet 1, a synthetic resin film such as polyethylene or polypropylene, or a sheet made of non-woven fabric or paper laminated with a synthetic resin such as polyethylene can be used, but it does not allow liquids such as urine to pass through. Even if the thickness of the film or the thickness of the laminate layer is thin, there is no problem with the percentage.

The inner nonwoven fabric 12 is preferably a wet or dry nonwoven fabric made of one or more types of fibers such as polyester, polypropylene, or rayon, and among them, one made of hydrophobic polyester or polypropylene is preferable. Also, the basis weight of non-woven fabric is 20
~100p 77112 is sufficient, and a suitable one should be selected from the viewpoint of durability and ease of use.As for the shape of the diaper cover, there are various shapes as shown in Fig. 1, Fig. 2, and Fig. 5. There are many options, but it is sufficient if the waist circumference 6, thigh circumference 5, length 7, etc. comply with JIS L-4211.

As the stretchable elastic member 9, a foamable urethane film,
It is possible to use urethane rubber film, rubber thread, or elastic synthetic resin film.These elastic members are stretched to a desired ratio, for example, about 1.5 times, and then hot-melted or heat-sealed in place. Adhesion 11
You can attach it using something like this. It is desirable to attach the elastic member to the outer longitudinal direction of the crotch area at a length of about 50% or more of the longitudinal length of the diaper cover in order to ensure a good fit to the child's crotch. The width of the elastic member 9 varies depending on the material, but in the case of a film, it is 5 to 5()a.
+, preferably 10 to 25 m5; if the width is less than 5 m, the desired effect will not be fully exhibited. Further, the desired effect can be sufficiently exhibited if the thickness is about 0.5 to 5 h6, but it is not particularly limited to this.

Furthermore, it is possible to further improve the fit by attaching an elastic member 10 to the back rest of the torso 9. As this member, the same one as the lowest elastic member can be used, but there is no need to attach it to this part. Also.

The present invention is characterized in that by covering the elastic member 9 attached to a liquid-impermeable sheet with a surface material 12 made of nonwoven fabric, the fit on the skin and the comfort on the body are greatly improved.

Figure 5 shows a cross section of the diaper cover of the present invention, which shows a case where a synthetic resin film such as polyethylene or polypropylene +5 is used as a liquid-impermeable sheet, and Figures 6 and 7 show a cross section of the diaper cover of the present invention. In this case, the laminated surface 14 may be on the inside as shown in Fig. 6, or the nonwoven fabric or paper surface 13 may be on the inside as shown in Fig. 7. You can also do this. In either case, the effects of the present invention are not affected in any way.

In addition, various commercially available absorbent pads can be used for the diaper cover for the absorbent pad of the present invention, but the present inventors have proposed a method from the viewpoint of ease of attaching the absorbent pad to the diaper cover. It is preferable to use a structure in which a pressure-sensitive adhesive is applied to an arbitrary position on the back surface of the absorbent pad, so that it can be temporarily attached to a diaper cover.
