Abstract
Abstract A disposable nursing pad is provided which comprises a flat but stretchable and conformable body constructed of a plurality of substantially coextensive layers and having a fibrous facing layer, an absorbent inner layer and a moisture-impervious backing layer. The coextensive layers may be constructed of compressively shrunk fabrics. The several layers of the pad are secured together at a plurality of circumferentially spaced zones by means of solidified, flexible strands of resin containing fibers therein, introduced by liquid stitching; or by sonically welding the layers of the pad together at the spaced zones.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
125 words
A disposable nursing pad in the form of a stretchable and conformable body having an inner surface adapted to conform to the contour of a human breast and an outer surface adapted to be received within a brassier which comprises a fibrous, fabric facing layer defining said inner surface, an absorbent layer substantially coextensive with said facing layer, a moisture-impermeable backing overlying said absorbent layer, and securement means for binding said facing layer, said absorbent layer and said backing layer forming a unitary pad, at least one of said layers being constructed from an extensible compressively shrunk fabric web providing stretchability and conformability, said securement means being defined by a plurality of securement zones spaced from one another circumferentially about the periphery of the pad.
Claim 2
Dependent Claim
125 words
A disposable nursing pad in the form of a stretchable and conformable body having an inner surface adapted to conform to the contour of a human breast and an outer surface adapted to be received within a brassier which comprises a fibrous, fabric facing layer defining said inner surface, an absorbent layer substantially coextensive with said facing layer, a moisture-impermeable backing overlying said absorbent layer, and securement means for binding said facing layer, said absorbent layer and said backing layer forming a unitary pad, at least one of said layers being constructed from an extensible compressively shrunk fabric web providing stretchability and conformability, said securement means being defined by a plurality of securement zones spaced from one another circumferentially about the periphery of the pad.
