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.
