A brief history of the Thermos® Bottle goes back to 1892. The glass vacuum flask was invented by Sir James Dewar of Scotland. It was intended to keep chemical experiments at a constant temperature. William B. Walker obtained the patent rights and founded The American Thermos Bottle Company in 1907. The first bottles in the Brooklyn NY factory were double-glass vacuum bottles and protected by a metal cylinder. Then in 1966, a new design was introduced. The Thermos bottles were made with a double wall of stainless steel. No glass was used. Now you could drop the bottle and not be disappointed with a broken glass insert.
Today, the latest design is a hi-end replacement for the Koozie® sleeve. It holds a soft drink can or a beer bottle, and keeps it cold for much longer.
