Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to disposable hygiene absorbent articles such as diapers, training pants for infants, and incontinence pads.

[0002]

[Prior art]

 BACKGROUND ART Heretofore, there have been known some articles of this type in which a stool holding portion is provided in a region where a wearer's buttocks are located. The known stool holding portion is provided with a recess in a liquid-absorbent panel of an article, and the opening surface of the recess is flatly covered with a liquid-permeable surface sheet of the article, or the surface is provided along the inner surface of the recess. The seat is dented.

[0003]

[Problems to be solved by the device]

 However, in general, as the surface sheet, a non-woven fabric that allows stool liquid content to permeate but does not allow stool solid content to permeate is used. The amount does not flow in, and the effect of providing the concave portion cannot be obtained. Also, in the case where the surface sheet is recessed along the inner surface of the recess, the stool solid content flows into the recess, but excrement solid content is transferred to the upper surface of the surface sheet by the wearer's movement and body pressure. It easily flows backwards and spreads to stain the wearer's skin. This dirt not only increases the time and effort required to replace the article, but also causes skin diseases.

An object of the present invention is to solve a stool holding portion which does not have the above-mentioned drawbacks by an extremely simple means.

[0005]

[Means for Solving the Problems]

 An article body is formed from a liquid-absorbent panel interposed between a liquid-permeable top sheet and a liquid-impermeable back sheet, and a stool holding portion is provided in the body in the region where the wearer's buttocks contact. Assuming a disposable wearable absorbent article, it is characterized by the following points.

That is, the holding portion has a recess extending from the top surface of the panel with which the topsheet is in contact with the bottom surface of the panel, and the opening of the recess in the topsheet located on the opening surface of the recess. And a valve portion formed by extending the surface sheet portion from the opening edge of the recess toward the center of the opening of the recess.

In a preferred embodiment, the valve portion is divided into a plurality of portions around the opening edge of the recessed portion, and the recessed portion is tapered from the opening surface to the bottom surface.

[0008]

[Action]

 Excreted stool pushes away the valve portion of the holding portion and flows into the recess. At this time, the valve portion is inclined toward the bottom surface side of the recess to introduce stool into the recess. After the stool has passed through the valve portion, the stool shows a tendency to restore if the stool is soft such as an infant, depending on the nature of the stool. The backflow to the upper surface of the is suppressed as much as possible.

[0009]

【Example】

 An embodiment of an article according to the present invention will be described below with reference to the drawings by taking a disposable diaper as an example.

In FIG. 1, the diaper comprises a liquid-permeable top sheet 1, a liquid-impermeable back sheet 2, a liquid-absorbent panel 3 interposed between front and back sheets 1 and 2, and front and back surfaces on both sides. It comprises a leg elastic member 4 interposed between the seats 1 and 2 and a waist fastening piece 5.

When the diaper is worn, the stool holding portion 6 is provided in a region where the buttocks of the wearer come into contact, more specifically, in a region where the anus faces.

2 (A) and 2 (B), the stool holding portion 6 includes a concave portion 7 formed in the panel 3, an opening portion 8 formed in the surface sheet 1 located on the opening surface of the concave portion 7, and a valve. It is composed of part 9 and.

The recess 7 is enlarged in a tapered shape from its opening surface to its bottom surface. However, in some cases, the opening may be as large as or larger than the bottom surface. The space volume of the recess 7 is preferably 100 to 10,000 mm ³ under a pressure of 100 g / cm ² or less. Such a recess 7 can be formed by squeezing or removing a part of the panel 3 in the thickness direction thereof.

The opening 8 is formed smaller than the opening of the recess 7. The valve portion 9 is divided into a plurality of pieces in the circumferential direction around the opening edge of the recess 7. When the surface sheet 1 is made of a non-woven fabric by the melt-blowing method, the openings 8 and the valve parts 9 can be formed by molding at the same time, but the non-woven fabric or other non-woven fabric is processed after the production. You can also buy it.

3 (A) and 3 (B), another embodiment of the stool holding portion 6 is shown. In this case, the opening portion 8a is larger than the opening portion 8 and has an elliptical shape, and the valve portion 9a is different from the opening portion 9 in the circumferential direction around the opening edge of the recess 7. It is formed continuously.

A non-woven fabric can be used for the top sheet 1, a plastic sheet for the back sheet 2, and a mixture of fluff pulp, a thermoplastic fiber, and a superabsorbent polymer which is compression-molded under heating can be used for the panel.

Although the valve portions 9 and 9a are shown slanted in the figure, it is not necessary to intentionally slant them in a state before stool passes through them. Then, apart from the case where the surface sheet 1 is inclined by its own weight, the surface sheet 1 may be substantially in the same plane as the other portions.

[0018]

[Effect of device]

 According to the article of the present invention having the above-mentioned configuration, the valve portion forming the stool holding portion is pushed away by the stool and inclines toward the bottom surface side of the concave portion forming the stool holding portion, so that the valve portion is funnel-shaped. The function can be achieved, and stool can be smoothly and promptly introduced into the recess. Also, after relatively soft stool stays in the recess after passing through the valve portion, the above-mentioned valve portion shows a tendency to restore, so that the staying stool flows back to the upper surface of the surface sheet and diffuses. Less is.

In the case where the valve portion is divided into a plurality of parts, the inclination is so easy, and when the concave portion is tapered from its opening face to its bottom face, Prevention of backflow becomes more effective.
