Abstract
Sanitary Napkins are disclosed having elastic means for providing a greater convex shape to the body-facing portion of the central absorbent and for enabling adhesive-free placement of the flaps of a winged napkin embodiment. The elastic means comprise one or more elastic strips disposed in tension across the transverse width of the napkin to exert compressive forces on the central absorbent element and cause the flaps to fold naturally inward on the undergarment facing side. Also disclosed is a winged napkin having longitudinally disposed elastic means in one or both wings to impart a concave shape to the undergarment facing side of the wings.
