  • Patent number: 11517925
    Abstract: A vessel for frying, baking or cooking foodstuffs, includes at least one visible first material and one visible second material, wherein at least the first material reversibly changes color thermochromically when heated. The coloring of the two materials is selected in order for a color difference between the two materials to change visibly when the vessel is heated.

  • Patent number: 9177460
    Abstract: The invention describes a pressure detection system for a pressure cooker, having a sensor (17) for detecting a pressure prevailing inside the pressure cooker by means of measured values, a computer unit (16) connected to the sensor (17), and a display (3, 4), wherein the computer unit (16) is designed to evaluate the measured values supplied by the sensor (17) and to establish whether at least one first threshold value (S1) has been reached. In order to indicate use-related wear, the computer unit (16) is further designed to continue a counter when the measured value reaches the first threshold value (S1) and to output a notification on the display (3, 4) when a predefined value of the counter is reached.

  • Patent number: 8820220
    Abstract: A pressure vessel includes a pot-like receptacle and a lid for placing thereon, the two being detachably locked together and including a circumferential sealing ring made of elastically yielding material which is located in the region of a circular edge of the lid and a circular edge of the pot for the purpose of sealing the interior against a drop in pressure. Sealing lips of the sealing ring come into close contact with the edge of the lid and the edge of the receptacle, in which case, for producing an automatic pressure-control mechanism, the sealing ring is formed over at least one portion of its circumference in such a way that it is deformed, under a pressure inside the vessel which exceeds a given value (response pressure), so as to form a venting gap between the receptacle and the lid.

  • Patent number: 8813989
    Abstract: The invention relates to a steam pressure vessel consisting of a receptacle and a lid, said receptacle and lid each having a long handle and being designed to be tightly joined together by way of overlapping peripheral segments along the lines of a bayonet catch, with the interposition of a sealing ring between the edge of the pot and the edge of the lid, characterized by the combination of at least two closing and opening safety devices, in which case a first safety device comprises a safety valve, the body of which is held in the open position by a spring-biased slide (10) until receptacle and lid are brought into the locked position by turning the two handles (1, 11) so that they lie one on top of the other with the coordinating peripheral segments completely overlapping, and a second safety device raises the sealing ring from the edge of the lid by means of a safety element (safety cam 7) spring-biased in the open position until receptacle and lid are brought into the locked position.

  • Patent number: 8733574
    Abstract: The invention relates to a valve unit for a pressure vessel, the latter consisting of a receptacle and a lid which can be placed on said receptacle in such a way as to make it pressure-tight and said valve unit including: a safety function, pressure-relief function and pressure indicator function; adjustable indicator levels and pressure levels; an indicator pin (4) or indicator piston (10) which is supported against an indicator spring (7), can move in axial direction and bears on its portion becoming visible upon pressurization, due to its emergence from a valve housing (12), indicator rings, for example, for indicating the pressure inside the vessel; and comprising a valve body (5) which is movable in axial direction against the action of an exhaust steam spring (6) and, in the closed position, rests against a seal seat (19), lifting off from this, when a given pressure inside the vessel is exceeded, to uncover a pressure-relief aperture (20), in which case both the indicator spring (7) and the exhaust ste

  • Patent number: 8517205
    Abstract: A pressure vessel including a container and a lid for placing thereon. By twisting the lid and container relative to each another, the container and lid can be detachably locked together by a peripheral locking segments configured along the lines of a bayonet fastening. A circumferential sealing ring is in the region of the lid edge and the container edge for sealing the interior of the container against a drop in pressure when said container and lid are in the locked position. The pressure vessel including an auxiliary device or aid for correct positioning of the lid on the container. The positioning aid comprising a downward-projecting positioning element in the region of the lid edge which, when the lid is correctly positioned on top of the container, can be inserted into a recess which is open towards the top and in the region of the container edge.
