IMPROVEMENTS IN COOKING UTENSILS

摘要

A cooking vessel comprises a container (1) having a close fitting lid (2) in which said lid has valve or vent means (6) therein adapted to allow steam and air to be expelled from the cooking vessel such that the interior thereof can be maintained under conditions of a partial vacuum. The valve or vent means can be associated with an audible indicator, such as a whistle (7, 8), to indicate the passage of air or steam therethrough.
