ABSTRACT:
A vacuum operated container holder includes a support having a valve actuated vacuum source coupled thereto for selectively applying a vacuum to a resilient horizontally extending container support member for holding a container in place thereon. In a preferred embodiment of the invention, the container holder valve is actuated by the placement of a container on the support platform and rotating the container to activate or deactivate the valve which couples the support platform to a vacuum source using a natural wrist motion.
