A container body 1 has a rim profile formed by folding sheet metal material. The profile defines at least two separate zones 14, 15 which are completely enclosed by the folded material and two runs of the material 5, 10 meet at the junction 16 between the two zones 14, 15 and are welded to one another at that junction. A lid 2 also has a rim profile folded from sheet material.
