Abstract
A method and apparatus are provided for removing closures from containers that are assembled in cases which are moved seriatum into position below multiple spindles arranged with respect to the container positions in the case. Each spindle has a non-rotatable internally threaded nut with a freely rotatable externally threaded screw therethrough, and a head unit for gripping a closure on the container. Axial displacement of the multiple spindles with respect to the containers causes the head unit of each spindle to grip a container only by its closure, if it has one thereon. Axial displacement of the screw with respect to the nut rotates the screw with sufficient torque to break any bond or seal securing the closure without need of holding the container to prevent its rotation.
