Abstract (en)
[origin: EP0980726A2] The container has body (1) and intermediate ring (3) of esp. aluminum or tinplate, and an edge flange and lid (4) of esp. aluminum foil. A common blank for intermediate ring and container body is punched out, and deep-drawn. The size of the overall impression is a result of ring width and body height. A cut is made in the vertical section of the wall between ring and body. The edge flange of the container body, the inner edge of the ring, and/or a rolled part are formed from the step. The deep-drawn container is then widened.
