Abstract

PURPOSE:To prevent leakage which possibly occurs around a substantially front half part of each of legs of a user by positioning both side parts of a first member the substantially front half parts of both legs and both side parts of a second member around the substantially rear half parts of both legs, and by setting the elastically resilient strength of the first member to a value which is greater that of the second member. CONSTITUTION:A resilient member 4 around each of legs is composed of a first member 4A and a second member 4b. The elastically resilient strength of the first member 4A is greater than that of the second resilient member 4B. Concave edges 13, 14 are formed along both side edges of a inside leg zone 12 located between the front and rear zones 10 of top and back sheets 6, 7. A water-nonpermeable plastic film having an elastically resilient strength which is greater than that of the top and back sheets 6, 7 may be applied over at least the center zone of the back sheet 7, intermittently by adhesive or preferably dot-likely by dots which are suitably separated from each other. With this arrangement, it is possible to completely urine to transmitting through the back sheet 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to disposable wearing articles, and more specifically:
Concerning wearable items such as diapers, incontinence pants, and training pants.

(Prior Art and Its Problems) Conventionally, this type of wearing article has been known to have an elastic member attached around the legs and an absorbent core interposed inside.

Depending on the product, for example, disposable diapers, regardless of whether the wearer is male or female, generally have more urine excreted from the front half around the legs than from the back half due to the position and orientation of the urinary organs. leaks easily.

However, in conventional articles, no improvement measures have been proposed regarding the elastic member in response to this problem.

An object of the present invention is to provide an article that can minimize or prevent leakage of excrement by taking the above-mentioned improvement measures.

(Means for Solving the Problems) In order to achieve the above object, the article of the present invention comprises a first and a second member as elastic members around both legs.

The central portions of the first and second members are located approximately at the center of the crotch area, and the opposite side portions of the first member are located approximately in the front half of the circumference of the legs, and the both side portions of the second portion are located approximately in the front half of the circumference of the legs. They are located approximately in the rear half of the

The elastic strength of the first member is made greater than that of the second member.

(Operations and Effects) In the article of the present invention having the above configuration, when worn, both side portions of the first member of the elastic member located approximately in the front half around the wearer's legs are located approximately in the rear half around the wearer's legs. The elastic member presses against the skin more strongly than both side portions of the second member. Therefore, it is possible to minimize or prevent leakage, which conventionally often leaked from approximately the front half of the wearer's legs.

Further, the central portion of the leg elastic member lifts the crotch area of the article to bring it into close contact with the corresponding body part. Moreover,
Since the central portion of this elastic member is continuous with both side portions of the elastic member located along the circumference of the legs, it is linked to the tension and contraction of the both side portions, even when the wearer does exercises such as walking. , the state of conformity is maintained. These benefits can be achieved by adding a water-absorbing core to the article.

This is particularly effective. When the core absorbs urine, it increases in weight,
This is because the inseam area of the article will sag.

By the way, by constructing the leg elastic member from the first and second members and positioning these members across the crotch area of the article and around both legs, it is possible to reach almost the front half of the leg elastic member as described above. It is possible to make the stretch elasticity stronger.

(Example) An example of an article of the present invention will be described below with reference to the drawings.

Leg circumference 2 and I! It has a (torso) circumference 3, and elastic members 4 and 5 are attached to each.

FIG. 2 shows an exploded perspective view of the article 1. The article 1 includes a stretchable/water-permeable top sheet 6, a stretchable/water-permeable backsheet 7, a mat or sheet-like water-absorbing core 8, and the surroundings of the legs. and a waist elastic member 4.5.

The leg circumference 2 is located on both side edges of the inseam area 12 located between
Although not shown, an impermeable plastic film with stronger elasticity and elasticity than the top and backsheets 6 and 7 is glued to at least the central area of the backsheet 7. In this way, urine can be completely prevented from permeating through the back sheet 7, and the elasticity of the fabric of the article can be strengthened. This can further improve the fit of the article to the body.

The leg elastic member 4 is composed of a first member 4A and a second member 4B. The elastic strength of the first member 4A is greater than that of the second member 4B. To make the elasticity strong, for example, the first member 4A is the second member 4B.
If the material, number, and cross-sectional area of the first and second 2
The members 4A, 4B have portions 4A, 4B that intersect near the center of the recessed edges 13 and 14 for forming the leg circumference, and extend from this intersection to the outer end, as the top and/or back. Adhesive 17 applied to the inner surface of the sheet
At the same time, the core 8 is inserted into the central area of the top and back sheet 6.7 without being fixed to any member such as the central portions 4A2, 4B. It is located at the bottom of the central area. However, the central portions 4Affi, 4B can also be fixed to the backsheet with adhesive. The waist elastic member 5 is adhered to the inner surface of the top and/or backsheet along the waist circumference 16 with an adhesive (not shown).

The outer peripheral edges of the top and backsheets 6.7 are bonded by heat sealing or adhesive. Although not shown, the core 8 has its upper and/or lower surfaces bonded to the topsheet 6 and/or backsheet 7 with adhesive. They are joined intermittently, preferably in the form of appropriately spaced dots. The thus constructed laminate is folded in half vertically at the center and joined at both sides using heat sealing means.
The article is constructed as shown in FIG.

Such an article 1 can be manufactured, for example, by the method for manufacturing disposable briefs disclosed in Japanese Patent Application No. 1-167224 filed by the applicant. However, the present invention is not limited to forming the article in the shape of pants or briefs, and as described above, the laminate is folded in half vertically at the center and both edges are heated. Fastening pieces, such as pressure-sensitive tape fasteners, are attached to both sides of the rear region 11 of the laminate, without joining with sealing means, as in conventional open disposable diapers, and the fastening pieces close the 81-layer body (fs product). ) may be fastened around the waist 16. Also, depending on the article, the core 8 may not be provided.

The top and back sheets 6.7 are made of stretchable and water-permeable nonwoven fabric, the core 8 is made of a molded mixture of fluff pulp and water-absorbing bomber particles, and the elastic member 4.5 is made of one or more strings or strips of rubber or plastic. Each film can be used.
