Abstract
A gimbal-type anvil for apparatus for testing in the integrity of a sealed container closure assembly. These assemblies generally comprise a container, a resilient sealing element mounted in the discharge opening in the container and a cup-like cap engaging over the stopper and seating it in place over the discharge opening in the container. The apparatus includes a force applicator for applying an external force to the cap in a direction to further compress the resilient stopper and a microscope to detect initial displacement of the cap relative to the container when the externally applied force exceeds the residual static force in the stopper. The gimbal-type anvil is operatively associated with the force applicator and consists of a housing and at least a pair of annular ring members pivotally connected to the housing about axes transverse to the longitudinal axis of the container closure assembly. The intersection of the pivot axes of the rings of the anvil define a pivot point disposed closely adjacent a feeler wall which engages the cap to apply a displacement force in the direction opposing the residual static force in the stopper.
