Tervis Tumbler Company is an American manufacturer of double-walled, insulated tumblers. The double-wall insulation is made by inserting a liner inside an outer shell, creating a layer of air between them. The two liners are then permanently fused together. The insulation reduces condensation and keeps beverages hotter or colder longer than non-insulated cups and glasses.
The original technology was developed by two engineers, Frank Cotter and G. Howlett Davis, in Detroit, Michigan in 1946. They created the first permanently sealed double-walled tumbler. Cotter and Davis combined the last three letters of their surnames to come up with the name Tervis. John C. Winslow purchased the Tervis product rights in the 1940s. The Tervis Tumbler Company was incorporated in 1967. All Tervis drinkware is still made at the Venice, Florida manufacturing plant.
Tervis sells branded drinkware through licensing agreements with all five of the major American sports leagues (MLB, MLS, NBA, NFL, and NHL), nearly all major NCAA colleges and universities, all branches of the United States Armed Forces, and many companies such as John Deere, Coca-Cola, Disney, Hello Kitty, Marvel, Nickelodeon, Warner Bros. and Lucasfilm.
Tervis tumblers are top-rack dishwasher safe and can go in the freezer. Tervis drinkware has been BPA free since 2011.
