Abstract
A method for testing tightness of container includes placing a bell-shaped test head over a mouth of the container, sealing the container against the test head, accommodating at least a portion of the container in a testing chamber within the test head, increasing a pressure difference between a pressure within the testing chamber and an internal pressure of the container, identifying evidence of matter exiting the container and entering the testing chamber. Typical evidence includes emergence of filling substance into the testing chamber and/or foaming of the filling substance in the testing chamber. Identifying such evidence includes using a camera to monitor either the region of the container or the test chamber for the evidence.
