A method and device for producing a rigid container, having two end walls and a lateral wall, from a flat blank having two flat first portions, each of which has a relative panel defining a relative end wall of the container, and a drawn rim integral with the panel, extending along at least one portion of an outer edge of the panel, and square with respect to the panel; and three flat second portions alternating with the two panels; each panel being folded squarely with respect to the flat second portions adjacent to it; the second portions being wrapped about and onto the rims to form the lateral wall; and each panel being stiffened by means of an external stiffening member, at least when forming the lateral wall.
