Claim 1
Independent Claim
260 words
A container screw-on cap remover, comprising (a) a split ring having a cap gripping inner surface about a central aperture adapted to receive a bottle cap, (b) and a pair of handles attached to said ring and extending in generally the same direction away from said ring, said handles being manually graspable and movable relatively toward one another to draw said ring surface into forcible gripping engagement with the cap, whereby the handles may then be rotated to rotate and loosen the cap, (c) the split ring consisting of an elastomer, and including a U-shaped integral extension of the handles extending part way about said elastomer split ring to provide a hinge and transfer torque to the split ring, the handles and U-shaped extension comprising a one-piece unit consisting of molded synthetic resin, (d) said U-shaped extension of said handles being integrally attached to said split ring, to transfer handle torque to the ring, the handles and U-shaped extension defining a single web which in turn defines a plane normal to an axis of said ring, (e) the handles being elongated and the web having flat sides for displaying indicia, the handles each having an I-shaped cross section in planes normal to the handle length dimension, and substantially throughout handle length, (f) said split ring interior surface being corrugated, the handles and ring defining cusps that project relatively toward one another proximate the split defined by the ring, (g) the handles and U-shaped extension having outer flanges that merge and define similar convex curvatures at opposite ends of the remover.
