The invention relates to container produced from a single-layered, helically bent sheet-metal trip (20), wherein 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), characterized in that the second, helically running 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), said third portion being adjacent to the bent-out edge (24) and extending in the direction of the second peripheral portion (26) front the bent out edge (24), and in that 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).
A container (10), produced from a single-layered, helically bent sheet-metal strip (20), wherein a first, helically extending edge section (22) of the sheet-metal strip (2) is bent outward toward the outside of the container (10) while forming a helically extending outwardly bent edge (24), characterized in that the second, helically extending edge section (26) of the sheet-metal strip (20) overlaps a third edge section (28) on the inside of the container (10) adjacent to the outwardly bent edge (24) and extending from the outwardly bent edge (24) in the direction of the second edge section (26), and that the second edge section (26) is connected in a fluid-tight manner to the third section (28) of the sheet-metal strip (20) on the inside of the container (10).
