Abstract
Abstract A beverage container lid is disclosed whereby the contents of the container may be accessed via a foldable tear strip flap defined by two score lines directed radially on the lid surface, a lift tab at the peripheral sealing skirt which mates with the rim of the container, and a multi-grooved hinge that allows for easy folding of the flap into a recess in the lid surface. Each of the two side walls of the recess has a retaining lug whereby when the user desires access to the container the flap is torn free of the peripheral sealing skirt by means of the lift tab, folded back, and inserted into the recess so as to wedge the flap below the retaining lugs which secure the flap by its opposite edges.
