Abstract
The invention relates to a pressure cooking utensil comprising a vessel, a lid with an annular skirt, and a gasket interposed between the lid and the vessel, said gasket including a ring and a first lip in sealing contact with the top wall of the lid, said utensil being characterized in that it includes a leakage opening formed through said top wall, the annular skirt forming a stop abutment for the ring, said first lip presenting flexibility that is suitable, when the pressure that exists inside the enclosure exceeds a safety threshold, for causing the inside of the enclosure to communicate with the outside through the leakage opening.
