ABSTRACT:
A can having a closure defined at least in part by a rupturable weakening line is provided with a finger-movable tab-like tool for safely opening the closure. The tool is a sheet metal lever pivotally attached to a can end in which the closure is deflectible and preferably non-severable. A depressor portion of the lever is raised from its prone or inoperative position and, in part, twisted about 90.degree. to locate its pressure-directing beak adjacent to a point along the weakening line, whereupon downward finger pressure on the depressor portion disrupts the line and deflects the closure inwardly. The lever is so shaped that depression of the twistable portion is limited by engagement therewith of an edge of the opening thus barring finger entry into the can opening as a safety measure. The lever may be provided at its opposite end with a handle whereby, when the closure has been opened as explained, the lever may be swung to clear the depressed end portion substantially from the can opening.
