Abstract:
A container is produced from a single-layered, helically bent sheet-metal trip (20). A first, helically running peripheral portion (22) of the sheet-metal strip (20) is bent out in the direction of the outside of the container (10) to form a helically running bent out edge (24). A second, helically extending peripheral portion (26) of the sheet-metal strip (20) overlaps a third portion (28) of the sheet-metal strip (20) on the inside of the container (10). The third portion is adjacent to the bent-out edge (24) and extends in the direction of the second peripheral portion (26) from the bent out edge (24). The second peripheral portion (26) is connected in a fluid-tight manner to the third portion (28) of the sheet-metal strip (20) on the inside of the container (10).
