  • Patent number: 5916337
    Abstract: A pull ring to facilitate opening of pop-top or pull-top cans. The pull ring consists of a flat portion with two attached arms. The two arms defining an opening large enough to accommodate entry of a portion of the tab of the closure of the pull-top or pop-top can. The two arms and the flat portion define a aperture in communication with the opening which is large enough to contain the handle portion of the tab. The ring has one or more protrusions on the arms, opposite the flat portion, to aid gripping. The ring is movable from a down position, where it protrudes minimally from the can surface, to a deployed position, where it remains in place by means of a flat outer surface of the flat portion resting on the can's surface.
