  • Patent number: 5071096
    Abstract: A drink container stabilizing device which normally rests upon a relatively horizontal surface for releasably holding various sized drink containers. One or more biased members, each of which are secured to the inner surface of a frame, releasably hold various sized drink containers within the frame's interior region. The frame has a top end and a bottom end which rests upon the relatively horizontal surface when the drink container stabilizing device is in a resting position. A retaining member may be used to further secure the one or more biased members proximate the top end of the frame, and a base plate may be attached to the bottom end of the frame so as to provide an underlying support for a drink container should the device be raised from its resting position. The base plate may further serve to secure the one or more biased members proximate to the bottom end of the frame.
