  • Patent number: 6877633
    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.

  • Patent number: 6604453
    Abstract: A steam pressure cooker, includes a pot with a horizontal pouring rim, a lid for closing the pot, and an elastic seal positioned between the lid and the pot. At least two moveable clamps are arranged peripherally in even spaced-apart relationship, for clamping the lid and the pouring rim, when the steam pressure cooker is closed, and clearing the pouring rim, when the steam pressure cooker is opened. The clamps and the lid are covered by a cap which supports a handle comprised of two handle parts, which are respectively connected to the cap and the lid. Actuation of the handle effects a coaxial rotation of the cap relative to the lid between two end positions, whereby in one end position the clamps are moved outwards, until the pouring rim is cleared. A tip clamping mechanism secures the cap relative to the lid in the end positions.
