PRESSURE COOKING KETTLE HAVING SEAL CERTAINLY PREVENTING PRESSURE DROP IN INTERNAL SPACE OF KETTLE

摘要

The invention concerns a steam pressure cooking pot consisting of a container accommodating the product to be cooked, a cover with safety valve capable of being placed thereupon, a locking means clamping container and cover to one another in the closed condition, and a seal disposed between cover and container securing the inside space of the pot against a drop in pressure in the closed condition, with a sealing lip of the seal pointing radially inwardly lying against the cover or the container which, upon pressing down on the cover in the direction toward the container, lifts off from the sealing emplacement on the cover or on the container, and with the cover or container, upon subsequent movement of the cover into the opening condition, executing a relative movement toward the sealing lip. Disposed radially outside the edge of the sealing lip, between the sealing lip and the cover or the container, is a slide element that acts as a levered support for the lifting movement of the sealing lip.
