The top of a metal beverage container, opened with a non-removable fulcrum-type lift tab, is modified, by the inclusion of a shallow channel, in order to facilitate initial lifting of the tab. The channel is positioned directly adjacent the pushing end of the tab and configured such that operative lifting of the tab causes the pushing end of the tab to fit within the channel and into pushing engagement with the container top at the base of the channel. The channel is configured into mirrored conformity with the pushing end of the tab, with the depth of the channel conforming to the shape of the pushing end of the tab to maintain full pushing engagement. The initial engagement of the lift tab with the channel results in a delay in container top opening and substantially less lifting pressure being needed to elevate the tab end for a finger to be more easily inserted for completion of the opening of the container. The maximum depth of the channel is such that it does not perceptibly impede container top stacking or prevent opening of the container.

A container comprising a container top and a lift tab non-detachably connected to the container top, wherein said container top has a dished section, of sufficient dimension to accommodate said lift tab therein, said dished section having a flat surface on which said lift tab is positioned in adjacent contact therewith, whereby the lift tab comprises a lifting end and a pushing end, with the lift tab being connected to the container top, between said pushing and lifting ends, whereby lifting of the lifting end causes fulcruming movement of the pushing end into pushing contact with a weakened section of the container top, within the dished section, and opening of the weakened section for access to the container contents, and wherein said pushing end and said lifting end each have lower flat portions which are aligned with each other in a common plane and wherein the lower flat portions of the pushing end and lifting end are each in adjacent contact with the flat surface, with the flat surface also being aligned in said plane, whereby access to and lifting of the lifting end is impeded prior to the opening of the weakened section; the improvement comprising a channel being formed in the container top, directly adjacent said pushing end, with said pushing and being aligned in said plane, and with said channel being positioned and configured such that, upon initial lifting of the lifting end, the pushing end enters into the channel, without impedance, thereby delaying said pushing contact for a distance sufficient to enable the lifting end to be raised, with reduced resistance, to enable finger insertion thereunder for continued lifting and opening of the weakened section, wherein said channel is positioned substantially perpendicularly across a longitudinal axis extending through said lift tab and wherein said channel is congruent with said pushing end, and whereby said channel extends sufficiently away from said axis whereby said pushing end fits into said channel, without impedance, and wherein said channel has a base, with said pushing end coming into substantially complete pushing contact with said base, wherein said channel comprises two opposing walls, with one of said walls being closely adjacent to said tab; and wherein said wall closely adjacent to said tab is formed with a reduced edge with the flat portion to permit said pushing end to enter into the channel without impedance thereby.
