Abstract: An apparatus for determining and displaying or monitoring at least one operating state, selected from the group of temperatures, pressure or air humidity, of a cooking vessel includes: an adjusting element for detecting the operating state, and a signaling apparatus having an acoustic signal transmitter and/or an optical signal transmitter and/or a display device. An actual value of the operating state can be displayed with the aid of the display apparatus, and an appropriate signal can be output when a setpoint of the operating state is reached. The adjusting element includes a pivotable measuring disc with a coded structure, and a sensor device is provided for sensing the pivoting path of the measuring disc.

Abstract: A cooking vessel has a handle, in particular for a pot or a pan, wherein the grip region of said handle is composed of metal. In this case, the handle has at least one first substantially metal fixing section for being fixed to the cooking vessel, a transition section and a substantially metal grip section. The transition section has a reduced metal cross section compared to the adjacent sections, wherein said transition section respectively comprises either a metal section, which is integrally connected to the adjacent sections, and a ceramic piece, or comprises only a ceramic piece, and the ceramic pieces are connected to the adjacent adjoining metal sections in an interlocking manner. The result of this is a reduction in thermal conductivity in the grip region without reducing the stability of the handle.

Abstract: A cooking vessel has a container having an encircling container margin bent outwardly and with a cover having an encircling cover margin bent outwardly. The container can be closed airtight by the cover with the aid of a closing mechanism acting on the container margin and cover margin. The closing mechanism comprises a closure ring extending over the container circumference with a C-profile cross section open radially inwardly, which, with the aid of an actuating mechanism, can be moved from an open position with greater diameter, in which the cover can be lifted from the container, into a closed position with lesser diameter, in which the container margin and the cover margin are clamped together by interspacing a sealing ring between a lower flank and an upper flank of the closure ring.

Abstract: The cover is intended for a container with an angled rim and has a sealing mechanism acting peripherally on the edge of the container. There is, around the edge of the cover, an open elastic metal sealing ring exerting a spring force which increases with the diameter of the sealing ring. In its position of rest the sealing ring is clamped between the end region of a part of the rim of the container and the end region of an annular angled section on the edge of the cover. The sealing mechanism comprises means for expanding the diameter of the sealing ring against said spring force.

Abstract: The cooking vessel comprises a container (1) and a lid consisting of an inner lid (3) and an outer lid (5). The container comprises a bent peripheral container rim (2) wherein twelve individual hook-like lock elements (21) are effective locking the cooking vessel. The lock elements (21) are arranged peripherically and swivellingly along the inner lid rim (4) so that through pressing the upper lid (5) against the lock elements (21) a swivel movement of said lock elements is obtained. The lock elements are C-shaped with a hook part (32), such that in the swivel position corresponding to the closed state, the ends of this hook part (32) grip under the outer container rim (2). In the swivel position corresponding to the opened state, the ends of said hook part (32) are in a distance from said container rim (2) allowing an unhindered lifting of the inner lid (3) from the container (1).

Abstract: A method of manufacturing a cooking utensil comprising a round container for the food. The container comprises a container, a plate made of heat-conducting material and a cap enclosing the plate, the cap being made from a sheet-metal disk and having a base provided with a convex curvature towards the container and also having collar which bears against the round container in a curved transition region between the container base and the container jacket. The container and the cap are made of stainless steel. The plate is intermetallically bonded to the container base and the cap. The plate, the sheet-metal disk and the container base are centered and connected by a central spot weld, using electric resistance welding. Next, the intermetallic bond is produced by single or multiple impulse pressure and permanent deformation and the cap collar is formed on the sheet-metal disk and its rim is placed around the container.

Abstract: A method of manufacturing a cooking utensil comprising a round container for the food, the container comprising a base, a plate of heat-conducting material and a cap enclosing the plate. A plate is inserted into the enclosing cap and leaves an annular flow space between it and a preformed collar on the cap. The assembly of the container base, the plate and the cap is centered between the ram and die of a press and intermetallically bonded by single or multiple impulse pressure, so as to form the convex curvature of the cap bottom and to mold the rim of the cap collar around the vessel. During impulse pressure, the plate is pressed by plastic deformation into the flow space, where it is intermetallically bonded to the cap bottom, the cap collar and the corresponding region of the container. Use is made of a plate having a base member which is circular in plan view and has at least three centering projections on its rim, around its circular periphery.

Abstract: A process for the application of twin layer bottoms on the pots, wherein the filling material of the hollow space is located on the bottom of the pot and kept at a certain distance from its profile, being a covering layer located above it, by operating them according to the Italian Pat. No. 965,732. The process is characterized in that the height of the filling material is at least 20% higher than the average thickness that the same material has at the end, and in that in the first phase of the deformation of this material a pressure is gradually applied from the center to the periphery, and in the second phase wherein the covering layer is kept in a mould and the filling material fills all the hollow space, said impact acts on said filling material in all the directions.
