A sanitary napkin including a stiffening means which because of its resilient properties enables the napkin to lie flat and help it to retain a large degree of its original configuration even after it is subjected to the type of compressive forces that occur during use, is disclosed. The sanitary napkin comprises an absorbent core; a liquid pervious material surrounding the core; a sheet of a liquid impervious material forming a moisture barrier and substantially covering the bottom portion of the napkin, the barrier being positioned between the core and the liquid pervious material; stiffener means located between the core and the liquid impervious material, and a plurality of track adhesive means disposed on the bottom portion of the napkin to secure the napkin to the crotch area of an undergarment, the stiffening means consisting of a material having a high enough level of resiliency and stiffness to resist side compression of the napkin to a sufficient degree to aid in retaining the multi-track adhesive means in place on the undergarment when compressive forces are applied to the napkin during use.

A sanitary napkin comprising an absorbent core; a liquid pervious material surrounding said core; a sheet of a liquid impervious material forming a moisture barrier and substantially covering the bottom portion of said napkin, said barrier being positioned between said core and said liquid pervious material; a plurality of track adhesive means disposed on the bottom portion of said napkin and spaced from the lateral edges thereof for securing said napkin to an undergarment; and stiffener means positioned between said core and said liquid impervious material the width of said stiffener means being at least equal in dimension to the distance between said track adhesive means but less than the width of said napkin, said stiffener means consisting of a material having a high enough level of resiliency and stiffness to resist side compression of said napkin to a sufficient degree to aid in retaining said adhesive means in place on said undergarment when compressive forces are applied to said napkin during use.
