The process consists in the manufacture of a parallelepipedal metal box body, called a tin (small container), where the starting point is a blank in the form a Greek cross, the branches 14-17 of which are raised up along the sides of the bottom 13 and the edges which have become contiguous are fastened in order to form the lateral ridges, in forming a blank from a rectangular central element 12 which creates the bottom 13 and two lateral walls 15, 17 and from two rectangular wings 14 and 16 which are fastened by their sides 14a, 16a to the corresponding edges 14b, 16b of the central element. This enables metal scrap on cutting out the blanks to be reduced and the tooling for cutting out to be simplified, whilst completing the box body on a conventional tool. <IMAGE>
