Feminine hygiene pad with foam absorbent and reservoir spacer layer

Abstract

Disclosed is a feminine hygiene pad with an absorbent system including: an absorbent foam layer having a wearer-facing surface and an outward-facing surface, having a plurality of apertures providing z-direction passageways from the wearer-facing surface to the outward-facing surface; and a porous spacer layer beneath the foam layer and underlying a majority of openings of the apertures in an outward-facing surface of the foam layer. The spacer layer functions to provide structure, beneath the absorbent foam layer, that holds open a desired amount of unoccupied space between the absorbent layer and a backsheet of the pad, into which unabsorbed menstrual fluid may flow and temporarily reside, during the time required for the absorbent layer to effectively imbibe the fluid.
