Metallic container partly openable by rupture of a line of reduced strength

A comprising a side constituting a partly openable lid having a fixed part, a line of reduced strength defining in said fixed part an opening panel, a connection zone remaining between said fixed part and said panel so that in exerting on said panel a pressure directed toward the interior of said container, said line of reduced strength is broken and said panel is swung toward the interior of said container about said connection zone, said fixed part of said lid being so shaped as to define a cavity extending toward the interior of said container, said cavity comprising a lateral wall and a bottom wall in which bottom wall said opening panel is formed at least partly, said container further comprising opening means which are movable relative to said panel in order to exert said pressure on said panel, said opening means comprising an element mounted to be rotatable on said fixed part of said cover about an axis oriented obliquely relative to said bottom wall of said cavity, an active part of said rotatable element extending inside said cavity in the vicinity of said opening panel.
