So that the second connecting portion of the edge of the first connection portion, the second connection portion is not only congruent with the first connection portion, but is also congruently arranged on the one or more wall members which together constitute the container.
  • the cover by the second connecting portion can be made depending on the manner of bending the first connecting portion. For the angling of the first connecting portion, it is preferred that the peripheral edge of the first connecting portion is angled at least approximately at 90 ° with respect to the plane of the flat material of the wall element.
