Abstract
A system for sealing threaded containers. The system includes a clutch-free spindle assembly which is easily disassembled and cleaned. The special interface between the exterior surface of the cap an the gripping jaws of the chuck allow the system to operate without the moving parts and complications that attend the use of clutch. The spindle assembly features an easily adjustable stop arm and a quick release pin for removing and cleaning the chuck. The chuck has several passageways for the rapid infusion of cleaning fluid.
