  • Patent number: 4207781
    Abstract: A device for opening a container having a ring-type opening tab secured to a removable section defined by a score line in one end panel of the container. The device comprises a main body portion provided with a generally curved surface for engagement with the one end panel and further having a handle extending in one direction from the main body portion and a projection extending in an opposite direction from the main body portion. In operation, the user grips the handle, inserts the projection into the tab, and wedges the projection between the tab and the one end panel of the container. A downward force is then applied to the handle such that the opening tab is lifted to remove the removable section.
