For over fifty years, THERMOS has been the standard of perfection for keeping hot or keeping cold. To insure fillers which will withstand wide temperature ranges and the terrific pressure of a vacuum, THERMOS manufactures its own crystal-pure glass especially for this purpose. Each filler must pass a rigid test for temperature retention before it is assembled into a vacuum bottle. These bottles have such exclusive features as the non-drip pouring lip and patented Polly Red Top® insulated stopperi, and a new plastic closure which even a child can remove easily. Be a smart shopper. For the finest vacuum bottle, be sure to look for the THERMOS name.
