A method and device for producing a rigid container, having two end walls and a lateral wall, from a flat blank (3) having two flat first portions (16,24,17,24), each of which has a relative panel (16,17) defining a relative end wall (5,6) of the container (2), and a drawn rim (24) integral with the panel (16,17), extending along at least one portion (22) of an outer edge of the panel (16,17), and square with respect to the panel; and three flat second portions (12,13,14) alternating with the two panels (16,17); each panel being folded squarely with respect to the flat second portions (12,13;13,14) adjacent to it; the second portions (12,13,14) being wrapped about and onto the rims (24) to form the lateral wall (7); and each panel (16,17) being stiffened by means of an external stiffening member, at least when forming the lateral wall (7). <IMAGE> |
