ABSTRACT:
A thin plastic disposable lid for use with a cup, typically a disposable plastic styrofoam or paper container, is disclosed. The lid includes a small foldback portion that is partially removed from the remainder of the lid by tearing it along tear lines that are coincident with the oriented fibers of the plastic material, thus creating an opening in the lid. No pre-formed score lines, slits or notches are required to facilitate proper tearing of the lid. Further, the foldback portion is hinged and retained in intimate engagement by the lid when it is fully open. A specific feature of the lid is that the foldback portion is easy to fold back and to engage. The foldback portion is also resealable over the opening in the lid.
