Abstract
A unitary opener device for tab-type cans, which is extremely inexpensive to fabricate, simple to use and reliable in operation. A first embodiment comprises a unitary member having a handle portion adapted to be gripped by a user, and a working end portion having a pair of relatively inflexible nose portions, the nose portions being separated by a slot dimensioned to receive the exposed portion of the can opening tab. One of the nose portions has a shorter length than the other, while each of the nose portions is provided with an external convex fulcrum surface adapted to engage the can surface bearing the tab to assist in raising the exposed portion of the tab away from the can surface and rupturing the seal between the tab and the can surface. A second embodiment comprises a unitary member having a handle portion adapted to be gripped by a user, and a working end portion having a single relatively inflexible nose portion dimensioned to be received in an aperture in the exposed portion of the can opening tab in frictional engagement therewith, so that insertion of the nose portion into the tab aperture, followed by rotation of the handle portion in a plane substantially perpendicular to the can surface, provides an opening force sufficient to rupture the seal between the tab and the can surface. The handle portion includes an inner surface with a portion adapted to contact the edge of the can, permitting the device to function as a handle.
