ABSTRACT:
An improved pressure cooker of the type having a container and a lid. The container has an open mouth with an outer rim having spaced, outwardly projecting rim portions. The lip includes a peripheral, depending lip provided with spaced, inwardly projecting lip portions. The lid is coupled to the container to cover the mouth by positioning and twisting the lid such that the lip portions engage the underside of the rim portions thereby coupling the lid to the container. A seal ring is interposed between the lid and rim. The lid further includes a pressure regulator. The improvement according to the present invention includes a safety valve formed by an aperture cut out of the lip between the lip portions and located to lie adjacent the seal ring. In response to overpressurization of the cooker, a portion of the ring is urged from between the rim and lid into the aperture to provide a passageway through which the pressure is allowed to escape.
