ABSTRACT:
An apparatus is provided for non-destructively testing for a predetermined minimum release torque of container caps on containers that are sequentially delivered to a torque testing station in the apparatus. The apparatus includes a device for delivering capped containers to the torque testing station; a device for clamping the containers at the torque testing station; a device for grasping the caps of the containers at the torque testing station; a device connected to the cap grasping device for applying a release torque to the container caps; and, a device including a strain gage coupled to the release torque applying device for sensing the level of release torque applied to the caps and providing a signal indicative of such level. Capped containers that pass the test are sequentially passed along for further processing (e.g., packaging and shipping) by the user, and those that fail the test are segregated in a reject area for reprocessing or destruction. The apparatus also includes selectively operable controls for destructively testing selected capped containers, on a sampling basis, to determine the actual release torque of the container caps on such containers.
