Abstract:
A container is produced from a single-layered, helically bent sheet metal strip. In the strip's upper or lower border region a first helically running border portion of the strip is bent out via a helically running outwardly bent edge with a curved region toward the outside of the container as a protruding flange. A second helically running border portion is in the lower/upper border region. The border regions each border one another adjacently height-wise and are connected to one another in a fluid-tight manner via a continuous, helically running welded joint. The second border portion runs rectilinearly in the plane of the strip and the welded joint has a first and a second weld seam. The first and second weld seams are applied from the outside and the inside of the container, respectively, and the two weld seams are fused to each other in the weld route thereof.
