ABSTRACT:
A lid for use on a drinking cup is provided having a central horizontal cover portion which has a vent means provided therein. The vent means comprise a circular, horizontal top portion having a vent opening therethrough. The top portion has a downwardly depending first wall which has terminal end below the surface of the cover portion. An upwardly extending second wall merges with the terminal end of the first wall and extends upwardly therefrom in an outwardly spaced apart position respect thereto so as to merge with the cover portion of the lid. A plurality of spaced apart ribs connect the first wall and the second wall so as to cooperate therewith the form downwardly depending arcuate wave dampening baffle means which encircle the vent means beneath the surface of the cover portion so as to prevent accidental spillage of the cup contents through the vent means.
