when were the first thermos flasks produced for commercial use
Thermos L.L.C. Invented in 1892 by Sir James Dewar, a scientist at Oxford University, the "vacuum flask" was not manufactured for commercial use until 1904, when two German glass blowers, Reinhold Burger and Albert Aschenbrenner, formed Thermos GmbH. They held a contest to name the "vacuum flask" and a resident of Munich submitted "Thermos," which came from the Greek word therme, meaning "heat."
