ABSTRACT:
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.
