Process for the manufacture of cooking vessels and vessels obtained according to such process

A process for the manufacture of cooking vessels, in particular pots and/or pans in a relatively soft metallic material, characterised in that it comprises the following steps:

• providing a metallic semimanufactured vessel (A) of the cooking vessel in a relatively soft metallic material, comprising a hollow (21) and a bottom portion (20);
• providing a substantially disc-shaped plate member (1), in a metallic material of a relatively high hardness, comprising an edge (3), a first surface (4) apt to be adhered to said bottom portion (20) and a second surface apt to be exposed to the outside and a plurality of holes (7), said plate member (1) being provided with a plurality of projecting members (6a, 6b) substantially subdivided in first points (6a), annularly placed at said edge (3), and second points (6b) formed at said holes (7);
• said second points (6b) projecting from said first surface (4) to form, from the apex thereof to the plane of the plate member (1), a substantially piramidal or conical duct and forming an angle (α) equal to or greater than 90° with the plane of the plate member (1);
• inducing, by compression of the plate member (1) at the bottom portion (20), the penetration of said first and second points (6a, 6b) and the adhering of said first surface (4) of said plate member (1) on said bottom portion (20), whereby the respective end of each point (6a, 6b) is crimped by bending in the thickness of the bottom portion (20).
