词汇	dewar flask
词源	dewar flask. The dewar flask, the original thermos bottle, is named for its inventor, Sir James Dewar (1842–1923), a Scot- tish chemist and physicist who devised the vacuum-jacketed vessel in 1892 for the storage of liquid gases at low tempera- tures. The thermos takes its name from the company that adapted Dewar’s invention commercially. Originally a trade- mark, the word is now spelled without a capital in most dictionaries.
