Abstract

A pressure cooker includes a container intended to hold cooking produce and which can be closed pressure tight with a cover that can be set on a rim of the container and locked thereto. The cover includes closing members movable between radially inward open positions, whereat the cover can be removed from the container, and radially outward locking positions, whereat the circumference of the cover is pressed against a region of the container rim with a circumferential sealing ring therebetween. The inside of the wall of the container in the region of the container rim includes a locking shoulder directed, for example, toward the container bottom, and a sealing shoulder directed, for example, toward the container opening. In the radially outward locking positions, the closing members are braced against the locking shoulder, thus pressing the sealing ring against the sealing shoulder.
