Abstract: The capsular heat-radiating base for a stainless steel cooking utensil is characterised in that a lateral wall of the external stainless steel covering of the capsular base which faces the utensil is perforated to allow the metal of good conductivity contained within the capsular base to be seen, the perforations having a configuration such as to form on the outer lateral surface of the capsular base the required graphic elements.

Abstract: The method enables a stainless steel cooking utensil to be formed with a decorated base, the base being of the type comprising three layers, of which one is an intermediate layer of a good heat conducting metal and the other two layers are of stainless steel. Compared with traditional methods for forming normal utensils of the aforesaid type, there is a further step of positioning on the outer stainless steel layer at least one sheet portion of a metal having a melting point not less than that of the metal forming the intermediate layer. An aluminum foil is interposed between the sheet portion and the outer stainless steel layer if the metal of the sheet portion does not enable a direct permanent connection to be achieved between the sheet portion and the outer layer. A decoration can also be obtained on the inside of the utensil base in a similar manner.

Abstract: In a cooking pan with a capsular base the lateral wall of the protection covering of the capsular base is shaped with raised portions and/or depressions obtained by providing corresponding recesses and/or projections in the relative region of the die of the mould used to produce the capsular base.

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.

Abstract: A container is equipped at the bottom thereof with an aluminum layer of considerable thickness, as compared with the thickness of the said bottom, the said layer incorporating a plate of rolled steel, thoroughly anchored in the said layer, in such a way that at least part of the surface thereof projects from the face of the said aluminum layer. To ensure the anchorage of the rolled steel plate, the latter is provided with openings through which the aluminum penetrates and wherein it anchors.
