  • Patent number: 5715772
    Abstract: An absorbent pad for animal accessories. The absorbent pad includes an absorbent layer having first and second sides. A one-way moisture barrier in the form of driweave is positioned proximate to at least one side of the absorbent layer. The barrier allows moisture to pass toward the absorbent layer and resists passage of moisture away from the absorbent layer. The several layers are encased in a mesh that protects the pad and provides support thereto for maintaining its shape. The layers may be stitched together to maintain their orientation. Optionally, deodorizer and disinfectant may be applied to the absorbent layer for neutralizing odors created by absorbed animal waste, as well as sanitizing it.
