Abstract
A disposable cup lid is provided for covering the open end of a beverage cup, especially a hot drinks cup for beverages such as coffee. The cup lid is a foldback lid, whereby an opening is formed in the lid by lifting and tearing the material of the cup lid at a designated portion of the rim thereof, then peeling back the drink-through portion of the lid, with the edges of the drink-through portion of the lid being defined by an orientation grain in the lid caused by extrusion of the sheet material from which it is formed. Two additional tab portions are formed into the rim of the lid, one at either side of the position where the grasp tab is located, so as to present forwardly extending tabs which are gently rounded at each edge of the drink-through portion of the lid after it has been formed, and thereby so as to preclude sharp edges at each edge of the drink-through portion being presented to the lips and tongue of the user.
