US Patent 7591393 Disposable drinking cup lid

A disposable drink-through dome lid for disposable drinking cups used in the sale of hot or cold beverages. In order to extend the volume within the cup, the top surface of the lid is elevated above the top surface of the beverage cup when in place, and is encompassed by an annular ridge that includes a generally oval-shaped opening for drinking. In its preferred form the ridge is not continuous around its perimeter but is partially recessed on both sides of opening. In its preferred embodiment the generally oval-shaped opening includes a barrier that projects downward from the opening's perimeter thereby providing shielding against accidental spillage due to sloshing of the beverage while transporting or consuming in a moving vehicle.
