Claims: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A lid for drink cups and the like comprising a body, sealing means on the periphery of the body to hold the lid on the top of the cup, a drink flap of limited width in the body that may be pivotally opened to permit drinking and pivotally closed to recover the limited drink opening, a first slit in the body and a pull tab on the periphery of the drinking flap, said pull tab being inserted in said slit when said drinking flap is in its open position selectively to hold the same in such open position.

2. The lid of claim 1 further comprising a second slit in the lid, said second slit perpendicularly intersecting the first slit to form a straw orifice.

3. The lid of claim 1 wherein the drink flap is initially defined by two spaced frangible lines of weakness in the lid body that must be broken to open the drink flap.

4. The lid of claim 3 further including pull tabs on the periphery of the drink flap proximate each line of weakness.

5. A lid for open top fluid containers and the like comprising a body, sealing means on the periphery of the body selectively to engage the top of the container tightly to hold the body on the container, a pivotal drinking flap of limited arcuate extent laterally described by two frangible lines of weakness in said body and said sealing means, said drinking flap having a pull tab on its periphery, and a straw opening in the body to receive said pull tab selectively to hold the flap in an open position after the frangible lines of weakness have been broken.
