Genuine Thermos vacuum-insulated bottle

Thermos is the pioneer brand that commercialized vacuum flask technology. It was originally founded in Germany in 1904 by Reinhold Burger and Albert Aschenbrenner, evolving from the scientific inventions of Sir James Dewar. The brand name became so popular that it eventually became a generic trademark in many jurisdictions.

Today, the brand is owned by the Taiyo Nippon Sanso Corporation based in Japan. While it traces its origins to German engineering and had major production historical hubs in the United States and England, contemporary manufacturing is largely centralized in China and Malaysia to meet global demand. Despite its international ownership and production, the brand remains a global household name for temperature retention technology.
