Technical Examples

A beverage bottle holder is adapted to hold a plastic beverage bottle and comprises a bottom collar adapted to accept the bottom surface of the beverage bottle; a top grasping member adapted to exert compressive forces against the outside surface of the beverage bottle to firmly holding the bottle in a stable configuration within the bottle holder; a handle and at least one sinusoidal cusp within the inner surface of the bottom collar. The cusp is adapted to mesh with concavities within the bottom of the plastic bottle. The bottle holder is specifically designed for use in combination with plastic beverage bottles by persons with reduced hand strength and motor skills due to age, infirmities and disease.
