Abstract

The invention relates to a pressure cooker with a container that can be airtightly closed with the aid of a cover, which can be placed upon a container edge and locked with it. A closing mechanism is provided on the cover. The closing mechanism includes a total of four arcuate closure members, acting distributively over the periphery of the cover and pivoted on the periphery of the cover. The closing mechanism can be moved by an actuating device from an open position, in which the cover can be removed from the container, into a locked position to extend underneath the container edge. In the locked position, the cover is pressed at its periphery against the container edge by interspacing an encircling ring. The total (for example four) closure members are combined into (for example two) groups of two closure members each of which are connected with hinges. Two adjacent ends of the (for example two) groups of closure members with the aid of the closing mechanism are simultaneously guided obliquely inwardly toward one another during closing, and during opening, obliquely outwardly away from each other.
