Anti-spill lid for a drinking cup

Abstract

A lid for a drinking cup comprises a circular disk-like body having a down-turned channel section formed continuously about the periphery for engagement with the rim of a drinking cup. The body has a stiffening arcuate rib spaced inwardly of the peripheral channel section. The rib extends less than a full circle about the body and has circumferentially spaced opposite end portions. A pair of stiffening ribs extend transversely from the ends of the arcuate rib to the peripheral channel section providing a reinforced space for a tear-out tab between them. The sides of the tab are defined by weakened lines extending along the insides of the transverse stiffening ribs and the outer end of the tab is defined by a weakened line consisting of a through-slit extending along the inside of the peripheral channel. The inner end of the tab is an open, manually liftable point defined by intersecting weakened lines comprising through-slits of a perforatable straw aperture. The intersecting through-slits are common to both the drink tab and the perforatable straw aperture. The lid is optionally usable in one mode in which a straw is inserted through the straw aperture while the straw itself is partially supported by the inner end of the drink tab and in another mode after the tab is removed to provide a larger, reinforced drink opening including part of the straw aperture.
