Abstract
An absorbent composite panel comprising a liquid-absorbent panel and a liquid-impermeable backsheet, wherein the top surface of the absorbent panel is partially covered along its peripheral edges with a liquid-impermeable overflow barrier strips which are then bonded integrally to the backsheet along their outer side edges and each inner side edge of the overflow barrier strips is spaced by each spacer from the top surface of the absorbent panel by a desired distance.
Claims5
An absorbent composite panel for pet animal waste comprising:
- an absorbent panel having peripheral edges;
- a liquid-impermeable backsheet covering the bottom surface of said absorbent panel;
- a plurality of liquid-impermeable overflow barrier strips, each one of said plurality of barrier strips being disposed along one of the peripheral edges and bonded integrally to said backsheet along an outer side edge thereof to provide a water-tight seal along the peripheral edges of said absorbent panel;
- and
- spacer means disposed between an inner side edge of each of the plurality of barrier strips and the top surface of said absorbent panel and attached to said panel for spacing each inner side edge of said overflow strips upward from the top surface of said absorbent panel by a desired distance.

- an absorbent panel having peripheral edges;
- a liquid-impermeable backsheet covering the bottom surface of said absorbent panel;
- a plurality of liquid-impermeable overflow barrier strips, each one of said plurality of barrier strips being disposed along one of the peripheral edges of said absorbent panel and formed by folding portions of said backsheet extending outward beyond the peripheral edges of said absorbent panel back onto the top surface of said absorbent panel to provide a water-tight seal along the peripheral edges of said absorbent panel;
- and
- spacer means disposed between an inner side edge of each of the plurality of barrier strips and the top surface of said absorbent panel for spacing each inner side edge of said overflow strips upward from the top surface of said absorbent panel by a desired distance.
