ABSTRACT:
Containers having top head openings are inserted axially without prealignment into a test chamber which houses a sealing member having a sealing surface radially continuous about the container insertion axis. The container interior and the extent of the test chamber encircling the container are commonly pressurized and the sealing device is displaced to seal the container openings. The encircling test chamber extent is then vented to atmospheric pressure and pressure change in the test chamber is monitored.
