ABSTRACT:
A unitary absorbent structure is provided with an absorbent pad that includes at least an absorbing layer of absorbent material for absorbing and holding body fluids. A facing layer of body fluid-pervious material is placed the adjacent the absorbing pad. The facing layer and absorbing layer are positioned in face-to-face contact with the contacting faces bonded together over substantially the entire contact area. A fluid-distributing layer may be adhered to one surface of the absorbing layer. A backing sheet may be disposed adjacent the absorbent pad, and edge portions of the backing sheet may be wrapped around the edges of the structure and heat sealed to the facing layer.
