CZ48898A3 - Absorption article used in case of incontinence - Google Patents

Abstract

An elongate sanitary pad comprises a fluid-permeable topsheet (1), a core (4), a secondary topsheet (5) located between the topsheet (1) and the core (4), and elastication means in the form of at least one longitudinally extending thread (7) located between the core and the secondary topsheet. At least one transverse elastic thread may also be provided.

Description

Absorbent article for incontinence

Technical field

The present invention relates to an absorbent article. In particular, it relates to an absorbent article, for example, in the form of a sanitary napkin that can be used by women suffering from cases of mild and mild incontinence. Thus, the invention will be further described. However, the invention has general applicability in relation to the absorption of body fluids such as urine and menses.

BACKGROUND OF THE INVENTION

One problem associated with these articles is that urine need not flow into and be absorbed directly into the article, but can flow along the user's body in the rearward direction and escape without ever entering the absorbent material of the article. This is particularly true in the case of urine outflows with low volume and low flow rates.

It is an object of the present invention to provide an absorbent article that is so shaped that these problems are eliminated or at least reduced.

SUMMARY OF THE INVENTION

According to the present invention, there is provided an elongated absorbent article that comprises a fluid-permeable topsheet, a fluid storage core, a receiving

2 a fluid layer disposed between the topsheet and the core for transferring to the fluid core passing through the topsheet, and elastic means disposed between the core and the fluid acquisition layer, wherein when the product is in its generally flat state the elasticizing means are stretched.

The fluid acquisition layer is hereinafter referred to as the secondary topsheet.

DETAILED DESCRIPTION OF THE INVENTION

In the embodiment shown in FIG. 1 to 3 is an absorbent sanitary napkin for use by women suffering from low incontinence. It comprises a fluid-permeable topsheet 1, a fluid-impermeable backsheet 2, which is sealed thereto by a gasket 3 at the periphery of the article, for example by heat sealing or adhesive. The article further comprises an absorbent core 4, for example one comprising absorbent gelling material (AGM), and a secondary topsheet 5, which serves to receive fluid and transfer it to the core.

The absorbent core may be those traditionally used for absorbent sanitary products. However, attention is paid to International Patent Publication WO94 / 28838 which describes an absorbent article having a high volume secondary topsheet, and to WO94 / O1O69 and PCT / EP94 / O4215 which describe AGM containing cores for further details of some suitable materials .

The product further includes an elasticization system whose function is to cause the product to curvature in a manner that allows it to closely conform to the body of the user and at least substantially prevent or reduce the risk of leakage of urine outside the user. In FIG. 1 to 3, the elastic system comprises an elastic fiber 6 which extends at least over a major part of the length of the article, preferably substantially the entire length of the article, below the secondary topsheet 5 and is attached at its ends or along its entire length or in selected points along its length, to the secondary topsheet and / or to the core. As can be seen, this causes the insert to accept a configuration that is upwardly concave as seen in the longitudinal section (Fig. 2) and convex upwardly as seen in the cross-section (Fig. 3). Thus, the pad is resiliently lifted towards the user ' s body and maintained in close contact with it, thus providing better fit and better ability to receive the smallest urine outflows. The core is relatively rigid and remains relatively flat in cross-sectional view, thereby allowing good contact with the wearer's panties.

Giant. 4 shows a modified embodiment which additionally comprises an elastic fiber 7 that extends transversely above the core and below the secondary topsheet 5 with the fiber 6. The transverse elastic thread affixed to the secondary topsheet 5, although if slightly longer could alternatively or additionally be attached to In each case, it is preferably fixed only at its ends. By pulling the sides of the secondary topsheet and / or the primary topsheet by its elastic 7, 4 is shown. · · · «A a a a a a a a a a a a

4 inwards, the transverse elastic thread aids in delivering the article, as seen in the transverse cut, desirable in the upward convex shape.

Various other treatments are also possible. For example, a plurality of transverse fibers could be provided, a plurality arranged closely to each other or spaced along the length of the article, and one longitudinal fiber may be. replaced by a plurality of longitudinal fibers arranged closely to one another.

Claims (7)

PATENT CLAIMS An elongated absorbent article comprising a fluid-permeable topsheet, a fluid storage core, a fluid acquisition layer positioned between the topsheet and a core for transferring to the fluid core passing through the topsheet, and elastic means disposed between the core and the fluid acquisition layer, the means the elastics are stretched when the article is in its generally flat state.
