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.

- 10. A method for testing a container that has been filled with filling substance and that has been closed with a valve, said method comprising placing a bell-shaped test head over a mouth of said container, sealing said container against said test head, accommodating at least a portion of said container in a testing chamber within said test head, increasing a pressure difference between a pressure within said testing chamber and an internal pressure of said container, identifying evidence of matter exiting said container and entering said testing chamber, wherein said evidence comprises one of emergence of filling substance into said testing chamber and foaming of said filling substance in said testing chamber, and in response to identifying said evidence, providing a signal indicative of said data indicative of a leak, wherein identifying evidence of matter exiting said container and entering said testing chamber comprises using a camera to monitor at least one of said region of said container and said test chamber for said evidence.
- 21. An apparatus for testing tightness of container that is filled with filling substance and that is closed with a valve, said apparatus comprising a bell-like test head configured for placement on said container in a region of said valve, wherein said bell-like test head comprises a test chamber, wherein said test head if further configured to accommodates the container in the region of a container sleeve thereof and said valve, and wherein said test chamber is configured to be connected to a pressure source, and a camera in optical communication with said test chamber of said test head, said camera being oriented towards said container in said region of said valve.
