Research - Essay Example One of his discoveries, that high vacuums can be created by using cooled charcoal, was quite useful in the field of atomic physics. The purpose behind the creation of the Dewar flask was to serve as an aid while working with liquid gases. The Dewar flask is a container to stores substances like liquid air in the hot or cold form. There is vacuum in between the two flasks it contains, which serves to prevent a change in temperature by reducing the transfer of heat. The glass walls are not strong heat conductors and the transfer of heat by radiation is further reduced by lining the walls with a reflective metal like silver. The flask is seated on a spring with a container made of metal or plastic to absorb shock. The air between the container and the flask serves to insulate the setup. Sir James Dewar had not manufactured the vacuum flask for commercial use. Two German glass blowers in 1904 formed Thermos GmbH (Bellis 2015). The concept of vacuum flask has been used in the making of insulated bottles. The well-known name Thermos was not registered until 1906 when William B. Walker learned of the innovation of Paalen, Burger, and Aschenbrenner and gained the rights of exclusive manufacturing and marketing of thermoses in the US (Bryk 2015). The thermos insulated bottle became popular all across the US in no time. The picture of the glass-lined aluminum vacuum sealed bottle is shown as follows: The bottle shown in the picture was made in 1915 by the â€Å"American Thermos Bottle Co. of Norwich, Connecticut† (Bryk 2015). In 1959, the company was named King Seeley Thermos (KST). The bottles were particularly used by outdoor laborers like construction crews who needed to keep the drinks hot or cold for extended periods of time. The raw materials mainly used to make thermos include stainless steel or plastic and glass. Stainless steel or plastic is used to make the outer cup whereas glass is used to make the inner cup. Nowadays, thermoses
