Abstract
An opener aid for pop-top containers and twist-off bottle caps is worn as a ring on the second joint of either right or left index finger and has a wedge-shaped spur or lug for insertion under the lifter or a pop-top can. The outside surface forms an engagement surface which may be knurled or corrugated to engage the adjoining corrugations of a twist-off bottle cap while applying torque thereto.
Claims8
An opener aid comprising:
- a ring, and
- a lug on said ring shaped to provide a wedge-shaped projection for insertion under the lifter of a pop-top container,
- whereby the user may conveniently actuate the lifter in response to an upwardly directed force applied by the user, and a circumferentially extending engagement surface on the outer periphery of said ring made of a material sufficiently resilient to obtain a firm purchase with the adjoining corrugations of a twist top removable in response to the application of torque.
An opener aid comprising:
- a ring-shaped member sized to be received on the index finger of a user, and
- a lifting lug on said ring projecting out of the circle loop of the ring to engage the lifter of a pop-top can,
- said lifting lug comprising a wedge-shaped element converging to a sharp edge to facilitate insertion of the edge under the lifter of a pop-top can,
- said ring-shaped member having a circumferentially extending external surface formed with knurling to provide an knurled engagement surface for engagingly abutting the corrugations of the twist-off container cap.

A container opener aid assisting a user to open containers comprising:
- a body member having a generally circular through opening sized to receive a selected digit of a user's hand, and
- a circumferentially extending surface on said body spaced radially outwardly of said through opening and forming a cap engaging surface,
- said cap engaging surface being formed of a material sufficiently resilient and elastic to facilitate a firm purchase with the adjoining knurled or corrugated surface of a twist-off container cap removable in response to the application of torque, and
- a lug on said surface extending circumferentially into a projecting relationship relative to said body and forming a wedge-shaped spur converging to a knife thin edge for insertion under the lifter of a pop-top container for convenient actuation of the lifter,
- said lug being formed as part of an enlarged portion on said body member and providing a flat surface suitable for containing indicia thereon,
- whereby said opener may be worn on the finger of a user to assist in opening pop-top cans and twist-off bottle caps without injury to the fingers or the hand.

An opener aid comprising:
- a ring-shaped unitary body member prescribing a single through opening sized to fit over the finger joints of a user,
- a lug formed as an integral projection from an enlarged portion of said body member and which extends across the width of the opener aid to form a pair of angularly intersecting flat surfaces,
- one of said flat surfaces together with a converging tangentially disposed portion projecting circumferentially out of the loop of the ring forming a converging wedge-shaped spur which tapers to a chisel point particularly adapted for insertion under the lifter element of a pop-top can,
- said flat surfaces forming indicia-bearing surfaces on which may be reproduced selected signal intelligence,
- whereby a user wearing the ring-shaped body member may conveniently actuate the lifter in response to an upwardly directed force applied by the user, and a circumferentially extending engagement surface on the outer periphery of said ring having knurling corrugations formed thereon to facilitate engagement with the adjoining corrugations of a twist top.
