Abstract
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.

A method of producing a rigid container for a product, the container (2) comprising two end walls (5, 6) and a lateral wall (7), and being formed from a flat blank (3) comprising two first portions (16, 24;
- 17, 24), each of which comprises a respective panel (16;
- 17) defining a respective said 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 (16;
- 17);
- and three second portions (12, 13, 14) alternating with said two panels (16, 17), one (13) of said second portions (12, 13, 14) being an intermediate second portion with respect to said two panels (16, 17);
- the method comprising the steps of folding each said panel (16;
- 17) squarely with respect to the second portions (12, 13;
- 13, 14) adjacent to it, and wrapping said second portions (12, 13, 14) about and onto said rims (24) to form said lateral wall (7);
- and being characterized by comprising the further step of stiffening each said panel (16;
- 17) at least during said step of wrapping to form said lateral wall (7).
