In 1892, James Dewar, a Scottish born scientist, working at
Cambridge University, invented the vacuum-insulated flask,
a scientific vessel for storing liquefied gases. It was not a
household item fit for everyday use like carrying warm coffee.
In 1903, the German glass blower Reinhold Burger received
a German patent for an isolating vessel for everyday use. In
1904, Burger registered the trademark Thermos for his patent.
In 1906, the company Thermos GmbH was formed by Burger
with Albert Aschenbrenner and Gustav Robert Paalen. The
production of Thermos-branded bottles in the United States
was based on US patent 13,093 by Burger and Aschenbrenner.
