<p>DISPOSABLE LID FOR DRINKING CUPS A disposable lid for a drinking cup is provided, where the lid has a generally circular cavity formed around the periphery thereof to accommodate the lip of the circular mouth of a cup, and so as to fit snugly thereover. The central portion of the lid is generally planar, and there is a skirt portion which depends downwardly and outwardly from the cavity, and has a pair of cuts formed therein at the rim and through the thickness thereof, the cuts being spaced apart from each other a distance less than 25% of the circumference of the rim -- generally they are spaced about 30 to 60 degrees apart. The rim cuts may be either notches or slits. A second cut is made in the central portion of the lid through the thickness thereof, in a place radially inwardly from the cavity but at a distance less than the radius of the lid, and has a length so as to extend at least between imaginary diameters that are drawn through the rim cuts.
