A sipper cup including a cup assembly having a plurality of threaded grooves formed adjacent a top opening thereof. Further provided is a cap assembly having a spout integrally formed on an upper surface thereof. The cap assembly is equipped with a plurality of threaded grooves for allowing the screwable coupling of the cap assembly with the cup assembly. Such threaded grooves of the cap assembly and the cup assembly are adapted to allow air to pass therethrough. Also included is an elastomeric insert including a spout valve for allowing fluid to exit the spout of the cap assembly only upon the application of suction. In use, air is allowed to enter the cup through the threaded grooves thus compensating for the vacuum formed in the cup assembly upon the exiting of fluid from the spout.

[ What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows:] [9.] A sipper cup comprising:a cup assembly having a plurality of threaded grooves formed adjacent a top opening thereof;a cap assembly having a spout integrally formed on an upper surface thereof and a lip integrally coupled to a periphery of the upper surface which depends downwardly therefrom, the lip further having a plurality of threaded grooves for allowing the screwable coupling of the cap assembly with the cup assembly, the threaded grooves of the cap assembly and the cup assembly shaped to allow air to pass therethrough; andan elastomeric insert including a spout valve for allowing fluid to exit the spout of the cap assembly upon application of a suction thereto and a generally rectangular cutout formed in a central extent thereof with a periphery having a semicircular tab integrally coupled thereto and residing in a coplanar relationship with the insert for allowing a user to selectively place the spout valve in the spout of the cap assembly and whereby air is allowed to enter the cup through the threaded grooves thus compensating for a vacuum formed in the cup assembly upon the exiting of fluid from the spout.
