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.

A non-spill drink-through lid for use on a drinking cup comprising: a lid having a central cover portion, said lid adapted to matingly engage the upper peripheral edge of a drinking cup so as to selectively maintain said lid in a covering relationship on said cup; a tab portion defined in said central cover portion of said lid, said tab portion selectively depressible so as to provide a drinking opening in said lid, said tab portion biased so as to selectively return to its normally closed positon within the plane of said central cover portion upon removal of pressure thereagainst; and a hollow lip-engaging buttress member integrally formed in said tab portion, said buttress member configured to provide increased heat-dissipating surfaces thereon so as to insulatively engage the upper lip of a user drinking from said cup through said drinking opening in said lid, said buttress member having a corrugated configuration comprising a plurality of arcuate narrow spaced-apart ridges having corresponding arcuate grooves positioned therebetween so as to insulatively engage the upper lip of a user drinking from said cup through said drinking opening in said lid, said ridges comprising narrow raised portions which define corresponding pockets on the bottom surfaces thereof so as to provide increased heat-dissipating surfaces on said buttress member so as to insulatively engage the upper lip of a user drinking from said cup through said drinking opening in said lid.
