Abstract
Abstract A sanitary napkin is provided which contains an absorbent core layer which is overlayed on its top and bottom surface with a secondary layer of reduced absorbency. The secondary layer has abutting faces adjacent each other on the bottom sides of the napkin. Adhesive is applied to a strip of nonwoven material which is positioned above the parallel faces of the bottom layer to maintain the napkin configuration.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A sanitary napkin comprising in combination: (a) an elongate absorbent core layer with a substantially planar body facing surface and an opposite substantially planar garment facing surface; (b) a wrapping layer overlying substantially both surfaces of said absorbent layer with said layer having two parallel longitudinally extending edge faces adjacent each other in butting or nearly touching, but not overlapping, arrangement of said parallel faces overlying said garment facing surface and essentially traversely, centrally disposed with respect to said garment facing surface, said wrapping layer having reduced absorbent capacity per unit weight relative to said absorbent layer; (c) an elongate strip of thin adhesive permeable nonwoven material overlying said adjacent parallel edge faces of said wrapping layer; and (d) pressure-sensitive adhesive strips which anchor said nonwoven strip to each of said parallel edge faces and provide for garment attachment when said napkin is used.
Claim 2
