Lid for a container

A non-spill drink-through lid is provided with a retainer support wall defined in a chord position across the central cover portion thereof. The retainer support wall merges with the raised outer peripheral edge of the lid to define a well portion which encompasses a depressible tab portion defined by a slit provided in the central cover portion. The well portion is adapted to retain excess liquid above the slit so as to permit the excess liquid to drain back into the interior of the cup upon which the lid is mounted. Another embodiment of the invention consists of the non-spill drink-through lid having a pair of identical parallel spaced-apart cup support walls defined in the central cover portion of the lid and extending thereacross to merge at the ends thereof with the raised outer peripheral edge of the lid. Thus positioned, the cup support walls are adapted to stackably support another cup positioned thereon.

Non-spill drink-through lid

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.
