1. A sanitary napkin having a substantially oblong body formed of a plurality of vertically stacked layers comprising an underply of fluid impervious material, an intermediate ply of absorbent material, an upperply of highly fluid pervious material, said intermediate ply being secured along uniformly spaced parallel lines so as to provide, in cross-section, a corrugated effect from which separate chambers are formed between the intermediate ply and said underply to minimize lateral flow of fluid, and a peripheral binding ply of fluid impervious material having an inner and outer peripheral edge and defining a central opening into the body, the body having one end larger than the other in the lateral direction such that, in plan view, the body generally resembles a figure eight configuration, said underply integrally formed with two planar projections one of which extends from the front edge of the last-mentioned ply and the other of which extends from the rear edge of such ply thus to define forward facing and rearward facing planar tabs that are aligned along the longitudinal axis of the body, each of said tabs including pressure sensitive adhesive means detachably to secure the same to an undergarment, said adhesive means including a removable protective cover, said plies being secured together about their outer peripheral edge and including an elastomeric member along each of the longitdudinal side edges of the body, which resiliently contracts the body in the longitudinal direction drawing the body in to a cup shape providing a deep compartment for retaining fluid between said underply and said intermediate ply and at the same time, raising the inner peripheral edge of said binding ply to form a continuous encircling wall against the flow of fluid from the compartment.
