ABSTRACT:
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.
