CANISTER WITH A SEALED LID

摘要

A canister has a base with a bottom, a side wall extending up from a perimeter of the bottom, and a top opening near a top end of the side wall. The canister can have a handle formed as a part of the back wall extending upward from the base above the side wall and around at least part of the top opening. The canister can also have one or more seals created at different points of contact between the lid and the base with the lid installed on the base. One of the seals can be formed between an upward facing ledge on the base and a downward facing shoulder on the lid. Another of the seals can be formed between an outward facing projection on a skirt wall of the lid and an interior surface of the base side wall. Another seal can be created between a gasket that is carried on an exterior surface of a lid skirt wherein a portion of the gasket bears against the interior surface of the base side wall. The canister can also have a positive lid retention structure. The structure can include one or more ribs that project inward from the base interior side wall and a snap projection extending outward from a skirt wall of the lid. The projection can snap downward over the one or more ribs with the lid installed on the base.
