Abstract:

A trash can wherein the open top of the container is surrounded by a ring-shaped rim having two inwardly extending prongs forming part of a bayonet mount. The lid of the can has a top portion and a depending annular skirt which can be inserted into the rim preparatory to activation of the bayonet mount which further comprises two inverted L-shaped slots in the external surface of the skirt. The lower ends of the slots are open to permit entry of prongs in response to placing of the lid onto the rim, and the lid is then turned relative to the container in order to cause the prongs to enter the substantially horizontal portions of the respective slots. The bayonet mount ensures that the lid cannot be separated from the container by dogs, bears, raccoons and/or other animals. In addition, the bayonet mount can maintain the top portion of the lid in substantial sealing engagement with the rim to prevent the escape of odors and/or flowable substances. The slots are disposed at the ends of a substantially diametrically extending grip at the upper side of the top portion of the lid to thus facilitate proper orientation of the lid prior to its connection to the container.
