Abstract
Abstract A sanitary napkin is provided with inwardly arcuate sides and elastic positioned centrally longitudinally along each of the sides and outward from the seal which attaches a fluid permeable cover directly to a fluid impermeable baffle. The elastic constricts the sides of the napkin to provide a cup-shaped profile with the bottom of the profile corresponding generally to the perineal area of the wearer.
