Abstract

An easy opening container having an end panel with push-in section and a non-detachable tab secured to the end panel and formed with a uniquely shaped lift end portion having an aperture therein sufficient to admit the nodes of the user's grasping fingers but of a size less than would permit inserting a finger therethrough and the novel construction of the tab and presenting a finger placement limiting edge which is adapted to position the fingers of the user such as to prevent the user's fingernail from being broken in attempting to open said container.
