A lid for beverage container having a top rim portion, comprising:

• (a) a cover section which is of a dimension to overlie said top rim section and having an outer periphery, an underside surface and an opening therethrough, said opening being defined by a leading edge, sides which intersect said leading edge and a rear edge;
• (b) means on said outer periphery for releasably engaging said cover section to said top rim portion;
• and
• (c) a bottom section having an outer end that is in engagement with said engaging means and being secured to said underside surface adjacent said sides and rear edge, said bottom section normally underlying and being in sealing engagement with said opening along said leading edge, sides and rear edge and including a passage therethrough which is movable between a normally closed position and an open position in flow communication with the interior of said beverage container and said opening, said passage comprising a slit disposed toward said outer periphery of said lid adjacent said leading edge and conforming to the contour of said outer periphery, said bottom section being elastically depressible to move said passage to said open position when force is applied to said bottom section so that said slit is moved out of engagement with said cover section along said leading edge while said bottom section remains in contact with said underside surface adjacent said sides and rear edge and to cause said passage to return to said closed position when said force is removed therefrom.
