Abstract

An absorbent article is provided for use in the perineal area of the body. Compliant sealing gaskets are pre-formed to extend outward from the central portion of the article. The gaskets may be formed by looping a strip of material so as to form a compliant cuff which bears against the user'"'"'s body in a comfortable manner. An elastic member placed in tension so as to impart an arcuate shape to the article may be placed inside a cavity formed by the cuff. The gaskets may be applied to an article having wings attached to the central portion so as to form pockets for retaining the elasticized portions of the panty crotch. The proximal ends of the gaskets are disposed outward of the pockets and the distance between the pockets is less than the width of the panty crotch so that the body facing said of the article is placed in tension.

Claims

1. An absorbent article adapted to be worn in a crotch portion of a user'"'"'s undergarment for use in the perineal area of the user'"'"'s body to absorb fluid, comprising:

a) a longitudinally extending central portion having (i) an absorbent core, (ii) a first layer covering at least a portion of said absorbent core and forming a body facing surface, said first layer having right and left approximately longitudinally extending edges, and (iii) a second layer covering at least a portion of said absorbent core and forming a second surface opposite said body facing surface, said second layer having right and left approximately longitudinally extending edges; and

b) right and left hand approximately longitudinally extending gaskets for preventing lateral leakage of said fluid, each of said gaskets comprising (i) a longitudinally extending portion of said first layer adjacent one of its said edges, (ii) a longitudinally extending portion of said second layer adjacent one of its said edges joined to said portion of said first layer so as to form a flange, and (iii) a strip of material enclosing at least a portion of said flange;

wherein said strip of material comprises a layer of flexible fabric and a layer of elastic foam laminated to said layer of flexible fabric and wherein said gaskets are pre-formed to extend outward from said central portion.

2. The absorbent article according to claim 1, wherein said first layer is formed from an apertured plastic film and said strips of material comprise a layer of fibrous non-woven material.

3. The absorbent article according to claim 1, wherein each of said strips of material forms a cavity between said strips of material and said longitudinally extending edges of said first and second layers.

4. The absorbent article according to claim 3, wherein each of said cavities forms a compliant portion of its respective gasket that is configured to deform in response to compressive forces imparted by said user'"'"'s body.
