A valved closure for a disposable drinking receptacle containing a consumable beverage is disclosed. The valved receptacle closure comprises a thin plastic cover having a peripheral groove adapted to sealingly engage with the rim of a drinking receptacle and a drinking opening therein through which the beverage is consumed. A slide valve is received in a recess formed in the cover and is movable into a closed position over the drinking opening. A releasable latch mechanism cooperates with the valve to secure the valve in its closed position against the force of a resilient member, such as a spring. When the latch is released, the resilient member urges the valve into its open position exposing the drinking opening to permit drinking therefrom.
