Vintage Eagle Brand vacuum bottle thermos history is tied to the broader
development of vacuum insulation technology and the rise of the Thermos
brand. While Eagle Brand itself is a specific manufacturer, its
vacuum bottles are part of this larger narrative. The technology
was invented in 1892 by James Dewar, and the commercial pro-
duction of vacuum-insulated bottles for everyday use, under the
brand name Thermos, began in 1904 in Japan.
