<p>The proposed excess pressure valve (10) for packaging containers (1) has a flexible valve diaphragm (11, 31) which is attached by its parallel edge regions (12, 13; 31, 32) and covers a hole in the packaging wall (2). In order to protect the packaging container (1) with the excess pressure valve (10) from theft, an alarm-triggering device (5) is incorporated in the excess pressure valve (10). The alarm-triggering device (5) is in the form of a strip which is glued to the valve diaphragm (11, 31) on one of the attachment edge regions (12, 13; 32, 33).</p> |
