Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an absorbent article for use in conjunction with other retention means for receiving body waste. More specifically, it relates to absorbent materials for use in diapers that can be used multiple times with other retention means, specifically, disposable diapers that require other retention means, and diapers for female sanitary use. The present invention relates to absorbent materials used as napkins, incontinence pads, and the like.

Generally known absorbent bodies such as disposable diapers have adhesive tape integrally installed as a fixing means, but absorbers of the type that use other holding means such as diaper covers are also known. ing.

The former type of fixation means can be used single-handedly, so
Although it is convenient for users such as mothers, it is difficult to be economical because it wraps around the waist of the wearer, requiring a large area, and the cost of the fixing means and the production loss when installing the fixing means are large. On the other hand, absorbent bodies that require holding means such as diaper covers are superior in terms of economy. However, in known absorbent bodies combined with a diaper cover, although excrement leaks to the outside through the diaper cover, it often leaks from the absorbent body and stains the diaper cover.

For this reason, the mother must wash the diaper cover separately, giving the impression that the intended convenience of use is not much different from when using cloth diapers. If the excrement is completely absorbed by the absorber.

The diaper cover can be used multiple times and is superior in terms of economy while being almost the same in convenience as a single-use disposable diaper. (For reference, in the case of cloth diapers, the diaper cover is changed 2 to 3 times on -day, so it is necessary to prepare a diaper cover for replacement.)

In the conventional technology, in order to prevent excrement from leaking out from the diaper cover, an elastic body is installed at the leg opening of the cover, and both ends of the elastic body are fixed in the stretching direction V, and the elastic body expands and contracts. A sole is formed around the legs to prevent the leakage of excrement2, and similar measures are taken in the case of integrated disposable diapers. However, with disposable diapers that are combined with a diaper cover, no measures have been taken to prevent leakage from the disposable diaper, perhaps because of the sense of security provided by the diaper cover's 4-bar effect, and excrement is absorbed. It has the disadvantage that it leaks from the body and stains the diaper cover.

The present inventors have developed diaper covers and the like that have improved these drawbacks.
As a result of intensive research to find an absorbent body that can be used in combination with other retention means, the present invention has been developed. Namely, the present invention is based on a liquid absorbing pad and a flexible structure that extends outward and is provided on both sides of the liquid absorbing pad. In an absorbent body including a lip, the lip is fixed to the optical surface of the absorbent body near both ends in the longitudinal direction, and an elastic member is fixed to the lip in a stretched state. The present invention provides an absorbent body.

In the absorbent body of the present invention, the part corresponding to the wearer's crotch area can be expanded and contracted by the elastic part fixed to the flexible edge, and the flexibility of the elastic member installed! , l are folded over the surface of the absorbent body and fixed near both ends in the longitudinal direction by fixing means such as adhesive, so that the elastic part of the elastic member is always stretched inside the absorbent body, It has the effect of covering the liquid absorbent pad including the flexible part and the excrement on the surface. Therefore, there is less contamination of the holding means such as the diaper cover due to leakage of urine, loose stool, diarrheal stool, etc., and there is an advantage that the convenience of disposing of the diaper is not impaired.

The present invention will be explained in detail below with reference to embodiments shown in the drawings. In these figures, a preferred embodiment of the absorbent article of the present invention having a liquid-absorbing pad and a flexible hem equipped with an elastic member, combined with other retention means, is shown for a disposable diaper. However, the present invention is not limited to these examples. FIG. 1 is a partially cutaway plan view of the elastic member of the disposable diaper in a stretched state, FIG. 2 is a cross-sectional view taken along the line A-A, and FIG. 3 is a cross-sectional view taken along the line B-B.

The male pair 21 according to the present invention has a back sheet 22
and two liquid absorbing pads sandwiched between the top sheet 23 and the back sheet 22 on both sides of the pad 24.
and a top sheet 23.
5 and is fixed to the surface of the absorbent body by adhesive means 27 near both ends. The position of the adhesive means 27 may be 5 or more distances from the side of the liquid absorbing pad 24 to the inside.
Preferably it is 10-50 mm.

Further, the adhesive is bonded along the elastic member from the end of the disposable diaper to the top of the liquid absorbing pad 24, and the length of the bonding line from the end of the diaper is preferably 5 mm to 100 mm. Further, it is not necessary to apply an adhesive means to the flexible portion of the diaper at the longitudinal end.

Before wearing the diaper 21 having such a structure, a recess is formed for receiving body fluids, etc., as shown in FIG. 4. When worn, other holding means, such as the diaper cover 28, can be used as shown in FIG. An absorbent cover that has a means for attaching the absorbent material to the body, such as absorbent covers that use durable materials such as wool diaper covers, materials that have been processed to provide a durable material, and moisture-permeable films such as VORE-TEX. .

In the present invention, the surface sheet 23 is generally
0-25? , /m' are used.

As the backsheet 22, a low-density polyethylene film with a thickness of about 25 tt is used, and a vapor-permeable, liquid-impermeable porous film is particularly preferred. The liquid-absorbing pad 24 is generally made of a cotton-like material obtained by crushing coniferous kraft pulp and wrapped in water-absorbing paper, and can contain a super-absorbent polymer if desired. Further, there is no particular restriction on its shape, and examples thereof include a rectangular shape as shown in FIG. 1 and an hourglass shape as shown in FIG. Generally, the adhesive used as the adhesive means 27 is preferably a hot melt type. Examples of the elastic member 26 include rubber strings, such as polyurethane threads of 1,000 to 2
000 denier is also available, but in order to achieve the purpose of the present invention, one with a tension of 50 to 80 F at 100% elongation is most suitable. When fixing the elastic member to the edge, both ends are glued while the elastic member is kept stretched.

The elongation rate at this time is preferably 50 to 100%, and is adjusted by the tension of the elastic member. For example, the tension at 100% extension is 5
In the case of 02, it is recommended to stretch it 100% and fix both ends with adhesive.
