The actual first producer of Styrofoam cups is unknown, but they were licensed by the Dow Chemical Company. One design for the cup was patented by Warren R. Price and Alexander S. Houston, of the Waxed Paper Company on May 9, 1957. A major manufacturer of these cups since the late 1950's is the Dart Container Corporation of Mason, Michigan. Dart also made foam bowls beginning in 1969.
Swedish inventor Carl Georg Munters first created closed-cell polyurethane foam in the early 1930's, and the process was rediscovered in 1941 by a Dow team led by Ray McIntire. Dow acquired the patents and trademarked the name Styrofoam.
