  • Power driven bottle cap remover
    Patent number: 4358970
    Abstract: A power driven device for twisting a crown cap from a neck of a bottle as the cap and neck are inserted into a cup shaped driven head that pivotally supports a number of cap engaging knives. The head contains a spring loaded member that moves the loosened cap outwardly with the neck, as the latter is withdrawn from the head. A sring mounted on the interior of the head separates the cap from the neck should the cap tend to cling to the latter.
