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.

A lid for mounting on the rim of a drinking cup comprising: a circular disk-like body having a circumferentially continuous, down-turned peripheral channel section engageable with the rim of the drinking cup; the body having a stiffening arcuate rib spaced inwardly of the peripheral channel section, extending less than a full circle therewithin, and having circumferentially spaced opposite ends; the body having a pair of circumferentially spaced stiffening transverse ribs extending transversely from the ends of the arcuate rib to the peripheral channel section; the body having a tear-out drink tab between the transverse ribs, the sides of the tab being defined by weakened lines extending along the insides of the transverse ribs, the outer end of the tab being defined by a weakened line extending along the inside of the peripheral channel section between the transverse ribs, and the inner end of the tab comprising a manually liftable portion defined by intersecting weakened lines of a perforatable straw aperture; whereby the intersecting weakened lines are common to the drink tab and the perforatable straw aperture; and whereby further the lid is optionally usable in one mode in which a straw is inserted through the straw aperture while the straw engages the inner end portion of the tab, and in another mode in which the tab is removed to provide a larger, reinforced drink opening including part of the straw aperture.
