thermos

Vacuum-sealed container

A thermos is an insulated container that keeps beverages hot or cold for extended periods.

The double-walled vacuum design prevents heat transfer, making it useful for coffee, soup, or cold drinks: She packed a thermos of hot cocoa for the hike.

Originally a trademark, the word has become generic for any vacuum flask. (Capitalized Thermos is the brand name.)
