DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pants-type absorbent article, and more particularly to an absorbent article which can be easily attached to and detached from a human body.

[0002]

2. Description of the Related Art Absorbent articles in the form of pants have been conventionally known, and are disclosed, for example, in JP-A-2-4364. However, this known absorbent article,
Because it has a complete pants form sealed on both sides, when using it must pass the legs through the leg holes,
At least there was the inconvenience of having to take off clothes such as pants and pants worn on the lower body. Both sides are fixed with adhesive tape or touch-closed surface fasteners to open and close, but it has been troublesome to fix both sides using adhesive tape or touch-closed surface fasteners. In addition, there is a possibility that the adhesive tape may adhere to the clothes while the clothes are worn.

SUMMARY OF THE INVENTION The present invention solves the problems conventionally encountered in pants-type absorbent articles, and does not provide an absorbent article which can be easily attached or detached while wearing clothes. It is assumed that.

[0004]

Means adopted by the present invention to solve the above-mentioned problems are a water-permeable top sheet, a back sheet, and an absorber interposed between the two sheets. A pants-shaped absorbent article having a back body and a crotch portion, wherein a front portion and a front body of the crotch portion are separated from each other, and can be connected by detachable fastening means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. Referring to the drawings, (1) is a disposable diaper formed in the form of pants according to the present invention, and as is well known in the art, a water-permeable top sheet (2), a water-impermeable back sheet (3), and both. A front body (5) covering the waist of the user, a back body (6), and a crotch part (7) covering the crotch part, which comprises an absorber (4) arranged between the sheets (2) and (3). including. The front body (5) and the back body (6) are fixed on both sides by heat sealing means and integrated. The rear part of the crotch part (7) is integrally connected to the back body (6), but the front part is separated from the front body (5), and the front body (5) is detachably attached to the front body (5). ) And can be connected freely. A leg hole (9) is defined by the front body (5), the back body (6) and the crotch part (7). The top sheet (2) is located in contact with the body when worn, has water permeability that allows the discharged body fluid to pass through, and preferably does not give the user a feeling of wetting when the body fluid passes. It has water-like properties and is preferably made of a synthetic resin nonwoven fabric or a porous film. Backsheet (3) is an absorber
It is made of a water-impermeable material that can prevent the liquid held in (4) from leaking to the outside, for example, a synthetic resin film that is water-impermeable to liquid but allows air to pass through.
The absorber (4) is preferably made of crushed wood pulp or a composite of a high-molecular-weight water-absorbing substance, and is preferably formed in a relatively thin shape and capable of absorbing and retaining a large amount of water.

The fastening means (8) for fastening the front part of the crotch part (7) and the front body (5) can be easily attached and detached like a touch-close type surface fastener or a pressure-sensitive adhesive tape. And means capable of maintaining a relatively strong fastening state. In the illustrated embodiment, the fastening means (8) employs a touch-closed surface fastener and is fixed to the inner surface (body side) of the front body (5) and the outer surface of the crotch portion (7),
The front body (5) is pressed against the crotch part (7) to fix it, but conversely, the outer surface of the front body (5) and the crotch part (7)
It is needless to say that the crotch portion (7) may be pressed against the front body (5) by being attached to the inner surface of the vehicle. The pressure-sensitive adhesive tape may be attached to either the front body or the crotch portion, and is covered with an easily peelable protective film before use.

[0007] Around the leg hole (9), an elastic body capable of shrinking the diameter of the leg hole (9) is attached to enhance the adhesion around the leg and enhance the fit of the article.
The elastic body may be arranged in a curved line along the arc shape of the leg hole, or may be arranged in a straight line, and if necessary, the curved arrangement and the linear arrangement may be combined. Further, it is preferable that an elastic body is disposed on one or both of the front body (5) and the back body (6) to enhance the adhesion to the body and the fit. Absorber (4)
May be in a flat form, but it is desirable to adopt a structure in which a middle part is bulged at a central portion corresponding to the depression of the buttocks to enhance the fit.

Although the illustrated embodiment is directed to a disposable diaper for infants, the invention is not limited to disposable diapers. Of course, the present invention can be applied to disposable diapers for adults and sanitary pants for women. When the absorbent article according to the present invention is worn, the crotch portion may be opened and moved to the torso portion through both feet, and then the crotch portion may be connected to the front body.

[0009]

According to the present invention, the crotch portion can be opened and moved to the torso through both feet, so that it can be worn without taking off clothes, easy to wear and remove, and easy to mount. There is an advantage that time is not required.
