## Claims

### Claim 1

A one piece molded polymeric device for removing removable portions of tops from receptacles comprising a substantially cylindrical ring portion for engaging the finger of a user, the cylindrical ring being open at both ends such that the finger of the user passes completely through the ring and frictionally engages the finger past the first joint, and an integral stem and hook for engaging a ring on the removable portion of the receptacle top, the stem extending parallel to the centerline of the cylinder and back toward the hand of the user and being tangent to the ring, and the hook depending from the stem outside the cylinder formed by the ring, the hook having a reversely curved portion extending backwardly toward the ring portion and aligned with the stem, the reversely curved portion of the hook being relatively flat and terminating in a tapered flat nose, the nose being the end of the device, the ring being provided with a cutout section along its length circumferentially opposed to the stem and hook so as to be semi-cylindrical in cross section to accommodate the user's fingers of differing thickness and diameter, the end of the user's fingers being completely exposed and uncovered.
