Abstract

Abstract A disposable cat litter container having the animal litter material prepackaged in the container. The container has a rectangularly shaped top wall member having a central perforated tear-out portion. Extending upwardly from the lateral edges of the top member are a pair of inside side walls and a pair of inside end walls. The top edges of these respective inside walls have outside side walls and outside end walls attached to their top edges. The outside walls have a height greater than that of the inside walls and each of these have inwardly extending flanges along their bottom edges. A bottom cover member covers the chamber formed between the bottom surface of the top wall member and the inwardly extending flanges on the outside wall members. This chamber is filled with a predetermined amount of animal litter material. The container, with the exception of the bottom cover member, is formed from a single integral sheet of paperboard material.
