Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a disposable absorbent article that absorbs and retains excrement, and can be suitably used as an incontinence pad, a diaper, or a sanitary napkin.

(Prior Art) In a disposable incontinence protector or diaper, an elastic member is attached to the outer edge of a side flap that extends outward from both lateral edges of an absorbent body, and the side flap is folded back to the upper surface and the folded portion is bent vertically. A device with both ends joined together and pockets provided on both sides to catch excrement was developed in JP-A-59.
-Disclosed in Publication No. 25741.

Sanitary napkins in which elastic members are attached to side flaps extending outward in the same direction from both lateral edges of the absorbent body are disclosed in JP-A-60-193461, JP-A-59-184820, and JP-A-59-184820. It is disclosed in 61-36618 and 61-51812.

(Problems to be solved by the invention) The above-mentioned known diapers and napkins are still insufficient in preventing the leakage of excretory fluid, and the insides of the diapers and napkins get stuffy while being worn, causing discomfort to the user. , which can cause diseases such as eczema on the skin.

The main objective of the present invention is to provide an absorbent article that can effectively solve the above problems.

(Means for Solving the Problems) The present invention comprises a water-permeable top sheet, a water-impermeable bottom sheet, a semi-rigid absorbent body interposed between the two sheets, and both lateral side edges of the absorbent body. an absorbent article comprising a flexible side flap extending outward in the same direction from the top sheet and having an elastic member attached thereto, the side flap being folded back to the upper surface of the top sheet, and both longitudinal ends of the folded portion being joined. It is based on the following premise and is characterized by the following points.

That is, the lateral outer part of the side flap is formed of a breathable and waterproof sheet separate from the upper sheet and the lower sheet, and the elastic member is attached within the outer edge of the outer part.

(Function) When the article of the present invention is held between the wearer's crotch, the side flaps in the crotch area are pushed outward by the vicinity of the base of the thigh. Since the side flap is fixed by joining its longitudinal ends, the elastic force of the elastic member located at the free edge, which is the outer edge of the side flap, is directed laterally inward, causing the side flap to rise. As a result, the non-fixed portion of the side flap expands the opening of the pocket for receiving excrement laterally outward.

(Example) Referring to the drawings and taking an incontinence pad as an example,
The present invention will be further explained as follows.

As shown in FIGS. 1 to 4, absorbent article A
, a water-permeable top sheet 1 , a water-impermeable bottom sheet 2 , a semi-rigid absorbent body 3 , and an elastic member 4 extending outward in the same direction from both lateral edges of the absorbent body 3 .
and a flexible side flap 5 with attached.

The top sheet 1 and the bottom sheet 2 extend outward from the outer peripheral edge of the absorbent core 3. The outer end 1a of the upper sheet and the outer end 2a of the lower sheet extending in the same direction from both ends in the longitudinal direction are joined to each other. The lower sheet 2 has a narrow width in the crotch area by cutting out a part of the outer part 2b to provide a recess 6. The inner side of a breathable and waterproof belt-like sheet 7, which is folded in half in the width direction and has an elastic member 4 stretched in the longitudinal direction within the fold, is joined to the outer side 1b of the top sheet and the outer side 2b of the bottom sheet. It has been done. In this way, the side flap 5 is formed, which is folded back inward to form the fold line 5a.
and the outer edge of the recess 6 are substantially aligned.
Preferably, the width from the folding line 5a to the outer edge of the side flap 4 is at least 2 mm.

The absorbent body 3 consists of a first absorbent member 3a and a second absorbent member 3b. The first absorbent member 3a has both lateral sides 3c folded inward in the crotch area,
In this part, the width is narrowed. The second absorbent member 3b is formed to have substantially the same width as the first absorbent member 3a, and is overlapped with the latter. Therefore, in the crotch area of the absorbent body 3, the area formed by the folding line of the folded side portion 3c, that is, the outer edge 8, and the longitudinal ends 9a, 9b cut for folding the folded side portion 3c. The rigidity is low, and a stepped line of the rigidity is formed by the side edge 8 and both longitudinal ends 9a, 9b, and the stepped line serves as a bending guide line 10. As shown in the figure, it is preferable that the position of the folded side portion 3c is biased toward the front end side in order to make the buttocks wider than the front portion.

The top sheet 1 and the strip sheet 7 are made of known non-woven fabrics, the bottom sheet 2 is made of plastic film, etc., and the absorbent material 3 is made of cotton-like pulp, paper cotton, alone or in combination, or mixed with super-absorbent polymer particles. , publicly known materials can be used.

Furthermore, as shown in FIG. 5, when the article A is an incontinence pad, a fastening sheet 11 attached to the lower surface of the article (see FIG. 2, (see FIG. 3), for example, by placing it on a urethane foam with a high friction coefficient or an adhesive sheet.

(3) Effects of the invention According to the article of the invention, which has the above-mentioned structure and the above-mentioned functions, excrement is sufficiently received in the pocket formed in the crotch area when worn, and does not come into contact with the wearer's skin. Since the lateral outer portions of the side flaps have breathable and waterproof properties, leakage of excrement and stuffiness can be effectively prevented.

Moreover, even if only the outer side portion of the side flap is formed of a narrow breathable and waterproof sheet, the above effect can be sufficiently achieved. This is because the outer part is the most important part in terms of breathability and waterproofing. Therefore, in order to obtain the same effect, it is not necessary to use, for example, a similar breathable and waterproof sheet for the entire bottom sheet, and the cost will not be higher than in the case of doing so.
