Abstract
A new, novel device for holding a container while applying torque specifically to the closure in the direction of opening. This device is readily adaptable for use with an electric motor or ratchet to provide hands free operation. The device may be made small enough to serve as a counter-top appliance for home use. In addition, the device is self sizing to serve a wide array of container closures.
