Abstract:

The present invention is directed at a lid for a cup. The lid comprising a disc having a periphery, a first face and a second face. The disc is corrugated to form a series of concentric, receiving channels having an opening and walls. The receiving channels are spaced apart so that both the first face and the second face can receive a cup wall of varying cup diameter. Additionally, the receiving channels have perforations to facilitate the removal of unused portions of the lid which extend radially outward from the cup wall. The lid has a tab which extends radially inward from the periphery of the disc and is formed by tab perforations on the disc. The tab hinges to the disc at a medial portion of the disc, and the tab can be opened by pivoting around the hinge and laying against the disc. Furthermore, the tab provides a starting point to tear along the perforations.
