Abstract

Abstract An elongated lever member is provided including first and second ends. The first end of the lever member defines a handle and the second end includes structure defining an endwise outwardly opening recess having a first narrow transverse dimension and a second wide transverse dimension several times as great as the first transverse dimension, the recess being provided to receive therein the left tab of a lift top can to thereby enable the lever member to be subsequently used as an operating lever to assist in lifting the lift tab. In addition, one side portion of the second end of the lever member includes structure defining a laterally outwardly offset hook opening toward the first end of the lever member, which hook may be engaged with a pop top tab in order to enable the latter to be subsequently at least initially displaced outwardly of the associated can end.
