ABSTRACT:
Container pressure testing apparatus includes a housing having an open portion for sealably engaging the container surface circumscribing a pour opening of the container. Pressurized air is issued from the housing through the pour opening into the container and, on preselected container pressurization, a closure member for the pour opening is displaced within the housing in the direction of the pour opening. On the occurrence of predetermined pressure-induced force on the enclosure member, the closure member is rotated into securement with the pour opening.
