DE 19527139 A UPAB: 19970512 One or more flat sheets are provided for the inner and outer section of the container. Stiffening elements are spaced apart and welded to the sheets, with the welding taking place on the inner or outer section side facing the corresponding outer or inner side. The depth of the weld seam in the flat sheet is less than the thickness of the sheet. The stiffening elements in the longitudinal direction have a variable height, especially with a constant pitch, so that the space from the inner and outer sections has a gradient. ADVANTAGE - The containers have increased rigidity
