ABSTRACT:
A container holding apparatus is configured for use with an associated piece of testing equipment, such as a torque tester for applying torque to a closure on the container. The holding apparatus includes a pair of selectively positionable gripping members which are mounted on and extend between a pair of drive screws of the apparatus. One of the gripping members is operatively connected with a clamp mechanism, which in turn is mounted on the drive screws. By this arrangement, conjoint rotation of the drive screws moves the gripping members toward and away from each other, with the clamp mechanism facilitating convenient gripping and release of a container after the apparatus is adjusted, by rotation of the drive screws, for the particular size of container to be tested. In the preferred form, the apparatus includes a support plate upon which the container rests as it is releasably gripped and held by the gripping members.
