Back to The Thermos Bottle: The technical name of a thermos is a vacuum flask (you will know the reason why, shortly). To keep your drinks hot or cold, it minimizes heat transfer due to conduction and radiation. Convection is not included because convection keeps the temperature in a liquid even.Oct 27, 2014
