Invention and History of Disposable Paper Cup(2)

It was in 1930s that saw an era of new handled cups for hot beverages. Few of them who have filed patents are, Sydney R. Koons from Ohio who filed a patent application for a handle to attach to paper cups in 1933. Another was Walter W. Cecil in 1936 who invented a paper cup with handles that resembled mugs. Soon the disposable cups were popularly in use around the world, and eventually there were many inventors inventing lids specifically for the disposable coffee cups. Later William F. Dart and along with his son William A. Dart, had developed expanded polystyrene foam cups in 1957. They even assembled a machine that manufactured these cups. Toward the end of the decade, around 1967, Philadelphian Alan Frank filed a patent for a tearable coffee lid and based on Frank’s tearable lid, a pull-back tab was invented in 1975.
