Abstract
Abstract A base is securable to the lid of a conventional container assembly which also includes a vessel. The base includes an inwardly directed flange which abuts the top panel of the lid and a downwardly directed flange which encircles the skirt of the lid. Upstanding from the base are lugs which provide diametrically opposed shoulders for receiving a leverage tool for the purpose of rotating the lid relative the vessel.
