ABSTRACT:
An article (20) which is adapted to be positioned adjacent, for example, to the body of an animal or of a human being is a layered structure which includes a liquid pervious layer (22) and a liquid impervious layer (26). The article is applied to cause the liquid pervious layer to be contiguous with the body of the animal or of the human being. Interposed between the liquid pervious and impervious layers is an absorbent core (24). The absorbent core includes at least one absorbent member (35) which comprises a relatively porous substrate portion (37) which has been impregnated with a superabsorbent material. Waste liquid given off by the animal of the human being passes through the liquid pervious layer and into the absorbent core. This causes the absorbent core to swell, absorbing the liquid uniformly and preventing pass-through of further liquid toward the outside as well as preventing flow back of the liquid into contact with the body.
