The rucksack, bag or container is made of flexible, coated, watertight and/or non-watertight materials and consists of parts made by overlap welding welded with a tool whose outer contour spans the periphery of the base and the edge by passing round part of the overlapping weld seam (2). The overlapping weld seam lies along the edge of the periphery (3), whereby at least one region of the edge is longer and the seam is further from the periphery in this region (4). |
