发明名称 Integral container made of metal which can be deep drawn, method for producing the latter and deep-drawing tool for carrying out the method
摘要 The container has a wall (2), shaped like the outer surface of a truncated cone, with a rolled edge (1). At the transition from the wall (2) to the bottom (3), there is a reinforcement in the form of a fold (5) pointing towards the interior (4) of the container. At this point, a reinforced point with triple material thickness is thus formed. The container is thus not susceptible to denting and has thin walls. The container can be produced, in particular, by deep drawing. <IMAGE>
