Abstract

A disposable absorbent garment includes a moisture impervious outer layer, a nonwoven moisture pervious inner layer, an absorbent layer sandwiched and encased between the inner and outer layers, with the sandwiched layers having opposed first and second waist edges and two opposed side margins. The garment further includes a fastener or closure system comprising a pair of gripping strips or extensions from each of the side margins along the second waist edge, each gripping strip having a plurality of first resiliently deformable connectors integrally formed therein. The fastener system further includes a pair of targets located on the outer layer along the first waist edge adjacent each side margin, each target having a plurality of second connectors integrally formed thereon which are adapted to engage the first connectors of the gripping strips. The first and second connectors comprise interlocking means of the fastener system and include a plurality of interlockable projections and receptacles. The projections and receptacles may be circular or of any polygonal shape or they may comprise interlocking ridges and grooves. In one embodiment, each of the first connectors is a receptacle comprising a throat which extends through the gripping strip, and each of the second connectors comprise a projection which projects through and interlocks with a gripping strip throat.

Dependent claims

A disposable absorbent garment comprising:

a liquid impervious outer layer;
a nonwoven liquid pervious inner layer;
an absorbent layer sandwiched and encased between the inner and outer layers, the sandwiched layers having opposed front and back laterally extending waist edges with a crotch region therebetween, and two opposed side margins extending generally in an axial direction between the front and back waist edges, the front and back waist edges for extending along the respective front and back waist edges for extending along the respective front and back waist portions of a wearer;
resiliently deformable gripping connectors extending from each of the side margins along the back waist edge, the gripping connectors comprising a plurality of projections and recesses formed by deformations of both the inner and outer layers;
and
target connectors along connectors along the front waist edge for engaging and securing the gripping connectors, the target connectors comprising a plurality of projections and recesses formed by deformation of both the inner and outer layers for engaging the gripping connectors, said target connectors adapted each to receive at least one of said gripping connectors by pressing the gripping connectors substantially perpendicularly toward the target connectors form either the inner layer or the outer layer, said gripping and target connectors being sized such that upon interengagement, at least one of said gripping and target connectors are deformed and said gripping and target connectors resiliently grip one another to maintain interconnection.
