[ What is claimed is:] [1.]1. A pneumatic containerholder adaptable for attachment to a structure, comprising:container receiving means for receiving a container therein and adapted to be attached to the structure, said container receiving means having a generally vertical axis and side walls spaced about said axis;inwardly inflatable bladder means disposed generally circumferentially about said generally vertical axis along said side walls, wherein said bladder means has a maximum gripping width when minimally inflated and a minimum gripping width when maximally inflated, wherein said maximum gripping width is substantially equivalent to an interior width as measured within said side walls proximate said bladder means; andpump means for selectively adjusting air pressure within the bladder means so as to vary the gripping width thereof between said maximum and minimum gripping widths.
