ABSTRACT:
A non-spill drink-through lid for use on a drinking cup having a depressible tab portion defined therein which is selectively depressible to provide a drink-through opening in the lid and which is biased to return to its normally closed position within the plane of the lid upon removal of lip pressure thereagainst. A raised hollow lip-engaging buttress member is integrally formed in the tab portion. The buttress member is configured to provide increased heat dissipating surfaces thereon so as to insulatively engage the upper lip of a user drinking from the cup through the drinking opening in the lid. A downwardly depending outwardly curved elongate annular skirt portion is provided on the lid which is configured to make sealing insulative engagement with the lower lip of the user drinking therefrom so as to prevent spillage and to avoid contact of the user's lower lip with the cup itself.
