    Abstract: A closure is provided for use with a beverage receptacle, such as a paper cup, having an open top. The closure comprises a planar lid having both an upper and lower side and conforming in shape to the open top of the receptacle. An annular rim extending outwardly from the lower side of the lid is dimensioned to frictionally engage the open top of the receptacle in order to secure the lid to the receptacle. The lid further includes a tubular spout extending outwardly from the upper side and adjacent the periphery of the lid. One end of the spout is open to the lower side of the lid while a cap integrally formed with the spout is secured to and closes the other end of the spout. A series of perforations between the cap and the spout permit the manual and permanent removal of the cap from the spout when consumption of a beverage within the receptacle is desired.
