Thermos vacuum flask or bottle

Thermos is the pioneer and leading global manufacturer of vacuum-insulated products. The brand originated in Germany in 1904, based on technology invented by Sir James Dewar. While the brand has historic roots in Europe and the United States, it has been under Japanese ownership since the late 20th century.

Today, Thermos products are manufactured primarily in China, as indicated by the 'Made in China' label on the bottom of this unit. The brand is managed globally through several regional subsidiaries, with the ultimate parent company being the Taiyo Nippon Sanso Corporation, a major industrial gas company headquartered in Tokyo, Japan. The brand remains synonymous with temperature retention technology worldwide.
