Abstract (en)
[origin: EP0318657A1] Beverage containers made of metal can be subjected during faulty operation of the pressure system to such a high pressure that they rupture. In order to provide a safeguard for this case, a tearing groove (14), which at least partially surrounds a surface region, is preferably worked into the top outwardly curved end wall (5). In the case of impermissible overpressure, transverse expansions occur in the material which lead to a crack beginning in the tearing groove (14), with the result that the bounded surface region folds outwards and the pressure medium can escape. <IMAGE>
