Abstract

A bicomponent material which allows liquids to pass in a first direction, but substantially prevents the liquids from passing in the opposite direction, is disclosed. The material also exposes any gases attempting to pass in the direction opposite to that of the liquid transmission to an odor control lamina. The material is especially suitable for use with articles which deal with bodily fluids and the gases generated therefrom.
