Abstract
A commodity container is provided that includes a cylindrical body that is preferably open substantially the full diameter at the top with an outwardly extending flange and an inner sealing band extending to a height above the top of the flange. On the body sits a removable lid having a cylindrical side wall depending down and terminating with an outwardly extending, wherein the lid is adapted to sit on the open end of the body with the lid flange above the body flange and the sealing band overlapping the lid side wall. A channel is formed between the inner sealing band, the body flange and the lid flange. A gasket is placed in the channel and the gasket is compressed between the body flange and the lid flange for sealing the container. The large opening of this container facilitates having commodity residue cryogenically cleaned from the interior. To cryogenically clean the container, it is placed in an enclosure with an opening in the top of the enclosure to permit access to the interior of the container when a container lid is removed. The system includes a rotating base to turn the container to facilitate freezing and removal of the residue.
