TESTING METHOD closed containers for leaks, METHOD FOR PRODUCING A hermetically sealed container and apparatus for leak testing

摘要

1. A method for testing a closed container for leaks, wherein the container has a flexible wall zone and an opening closed by a flexible sealing element, the method comprising applying of force to said flexible wall of said container and measuring the resulting force using a force sensor located adjacent to said flexible a closing element or in contact with it, and determining whether said container having a sealed or leak, as a function of said sensor output signal ly. ! 2. The method of claim 1, further comprising! sampling the first value indicative of the strength of the signal dependent from the output signal at a first time,! sampling a second value indicative of the strength of the signal depending on the output signal for the second consecutive point in time! forming a difference signal based on said first and second signals indicative of force as a signal indicating a leak, and viewing of said sealed container when said difference signal meets the criterion for the test. ! 3. The method of claim 1, further comprising attachment of said forces by moving the displacement member to said flexible wall zone on it. ! 4. The method of claim 2, further comprising attachment of said forces by moving the displacement member to said flexible wall area and to it and the termination of said movement of at least said first time. ! 5. The method of claim 2, further comprising monitoring a signal indicative of the force on the
