ABSTRACT:
A steam pressure cooker includes a pot having an outwardly directed horizontal pouring rim and formed with a V-shaped circumferential depression which points inwardly to define a conical surface in an upper rim area. A lid can be placed upon the pot for closing and includes a circumferential groove. Positioned between pot and lid is a rubberized elastic sealing element which is held in the circumferential groove. The sealing element has a sealing body of substantially U-shaped configuration to define two sealing lips in coaxial parallel relationship to the vertical pot axis. One sealing lip bears against an inner wall of the pot and interacts with the conical surface of the pot, when the lid is placed upon the pot. A locking mechanism embraces and thereby clamps the lid and the pouring rim, when the steam pressure cooker is closed, and clears the pouring rim, when the steam pressure cooker is opened.
