Abstract
The opening device is for aiding the opening of containers having either the non-detachable, component type opening system or the twist-off type cap. The former system being characterized as having a scored section at the top of the container with an empaling tab in fulcrum alignment attached thereto. The opening device includes a unitary body member which has a leading end portion for sliding beneath the empaling tab and a trailing handle portion for grasping by the user, and tab restraining means for engaging the top of the empaling tab as the leading end portion is placed beneath the tab. The tab restraining means project upward from the side edges of the body member and then projects spacially parallel to at least a portion of the upper surface of the body member. After placement of the device with the leading end portion beneath and the tab restraining means above the empaling tab the user grasps the handle portion and lifts it upward and in a forward direction, thereby, easily separating and pushing downward the scored section of the opening system. Thus, access is gained to the container by the leveraged, mechanical advantage of the opening device. At the trailing handle por…
