Abstract
Abstract An anatomically-contoured sanitary napkin whose shape blends in with female anatomy and which is adapted to be secured to the wearer without a supporting belt. The napkin is constituted by a backing formed of an impermeable film having a spoon-bowl shaped well therein whose opposite ends merge into flat, tapered extensions for connecting the napkin to body patches. Received within the well is a pad of absorptive material which conforms to the shape thereof. Marginally secured to the periphery of the well and to the extensions, is a porous facing sheet or lining.
