  • Can opening device
    Patent number: 5095777
    Abstract: A one-piece elongated body has a widened handle end portion at one end and a sharpened nose end portion at the other end. A slot extending lengthwise of the body opens generally centrally of the nose end portion. A can of the type having an opening ring attached to a lid separable from the base of the can by manipulation of the opening ring can be opened easily by use of the device by either: (1) inserting the nose of the device through the aperture of the opening ring until the ring engages in a notch adjacent to the nose portion, whereupon the device can be pulled for separating the lid from the can; or (2) sliding the device toward the opening ring such that the ring is fitted in the slot, wedging the ring upward by upward-swinging of the device, followed by turning the device such that the ring is fitted sideways in the slot and rotating the device in a screwing motion for peeling the lid from the can.
