Abstract
A disposable dome lid is provided for use with a drinking cup such beverage cups used for the sale of hot and cold beverages. The top surface of a dome lid is elevated above the top surface of the beverage cup rim, when in place. The dome lid is configured so as to make a plug fit onto the beverage cup by the beverage cup rim extending into a downwardly facing recess formed for that purpose. A side surface depends downwardly from a substantially planar top surface of the lid, and is inset from the cup rim engaging recess. A portion of the side surface is displaced outwardly towards the outer periphery of the dome lid, and thus provides a surface for engaging the lower lip of the mouth of the user. A tear-back flap is defined by fault lines stamped into the top surface and a "U"-shaped hinge formed in the top surface. When the tear-back flap is folded back, a locking stub extends downwardly into a locking recess formed in the top surface of the lid, and a drink-through opening is thereby created in the top of the dome lid near the outer periphery thereof, for easy drinking access to the beverage in the cup.
