Process and device for testing the tightness of evacuated packaging containers

摘要

Invention Patent: B "PROCESS AND DEVICE FOR TESTING THE SEALITY OF EVACUATED PACKAGING CONTAINERS" D. A device (10) for testing the tightness of evacuated packaging containers (1) has a bell-shaped housing (31, 36) with a distance sensor (20) which is connected with a pressure source (23). The distance sensor (20) and a pressure sensor (25) conduct their signals (U, P) to a control set (28) as input values that intertwine the two signals (U, P). The test processes that can be carried out with the device (10) make it possible, in addition to the indication on packaging containers (1) watertight or not, the possibility on the indication of the internal pressure (Pi) prevailing in the respective packaging containers (1) .
