ABSTRACT:
A pressure tester (50) is provided for safely and efficiently buckle testing a container (120). A housing (52) encloses a test chamber (54) and the related operating equipment. The chamber (54) includes a neck block (80) and a cradling assembly (82) for holding the container (120) therein. Upon activation of a test cycle, the container (120) is punctured on a domed end (124) by a hollow needle (100) which fits within a domed pedestal (94). The container (120) is pushed into the neck block (80) where an outwardly sloping surface (130) generally matches a neck (126) of the container (120). A flexible seal (134) is fitted within a groove (132) in the surface (130) which provides flex without support if the container (120) expands during the test.
