<p>The invention relates to a pressurised container, particularly a battery canister (1), having a safety weak point in the form of a weakened line on the housing which breaks in the event of an increased internal pressure. In order to ensure defined, rapid opening, and to produce a greater opening, with simple manufacture, a single weakened line is provided in the form of a tongue-shaped curved line (17), the tongue pivoting outwards about the imaginary connecting line (20) between the free ends of the curved line (17) when it is activated. <IMAGE></p> |
