Abstract
An animal proof container is set forth. The container comprises a can having a bottom, a sidewall having an inside surface having a plurality of substantially flat portions each having a recess defined thereby, an outside surface having a corresponding plurality of holes communicating to the recesses and a rim defining an open top. A lid of the container has a cover portion adapted to cover the open top of the can and a plurality of members extending downwardly peripherally from the cover portion, fitting adjacent the inside surface of the can and having lower end portions adjacent the flat portions of the inside surface, the lower end portions being biased outwardly towards the flat portions sufficiently to proceed into the recesses when the lid is pushed fully downwardly onto the can. The lid is biased normally upwardly relative to the can sufficiently for preventing the lower end portions from entering the recesses. Food stored in such a container is protected from the attacks of animals, including large animals such as bears. Yet, a human can readily open the container. The container can also be made relatively light in weight.
