Abstract
The invention relates to a metallic container particularly for foodstuff or beverages comprising a circumferential wall, a bottom and a lid, in which container is prevailing a lower pressure than the atmospheric pressure in the filled and closed state. The invention has for its object to construct a metallic container in a manner such that the desired mechanical strength can be obtained even with a very small wall thickness and hence at very low costs of material. The invention has furthermore for its object to design a metallic container in a manner such that the probability of undersirable deformation is substantially excluded. For the above-mentioned purposes the invention provides a metallic container the circumferential wall of which has at least one zone that can be pressed inwards by the effect of the difference between the atmospheric pressure and the pressure inside the container.
