Kan already knows certain attempts to increase the 11 derstandsfähigkeit of Fassern with respect to axial constrictions. For this purpose, it was proposed that a number of cavities should be formed in these transition areas by pushing the metal back from the outside inwards in such a way that these transitional cavities always lie within the normal fitting diameter. However, these attempts yielded not the desired reinforcement, would make it possible to use a noticeably thinner sheet metal for a predetermined strength,

In terms of the solution to this problem, the invention is based on a metal case with a cylindrical Esit jacket, the generatrix of which has at least one "lamellar line" which merges into a straight line via roergangiT.vellen.

■ The corrugations according to the invention are advantageous in each case with equal center of curvature distances in the axial direction arranged to one another. Their presence ensures in any case that the transition areas between the areas with stiffening corrugations and the respective adjacent cylindrical areas have the shape of corrugation areas, their ', bulge in the direction of these stiffening corrugation areas are carried out according to the invention with progressively larger, based on the barrel cuts radius of curvature.

Such an arrangement also allows progressive transmission of axial forces. These vertical axial forces come either from the lower or from the upper part of the barrel and become progressively without cracking from the part forming the resistant part of the barrel

Cylindrical inner area to the or \ v ₀ den '. Vellungsbereich of the jacket, which give the jacket the desired flexibility. The direction of transmission of the axial forces enforced in this way avoids the local accumulation of deformations in the outermost regions of the veil, which form the weak zones mentioned at the beginning. · - -;
