Thermo vacuum flask, also known as a thermos, is a type of insulated container designed to keep liquids hot or cold for extended periods of time. It consists of a double-walled container, typically made of stainless steel, with a vacuum layer in between the walls. The vacuum layer creates an insulating barrier that minimizes heat transfer between the inside and outside of the flask, keeping the contents at the desired temperature.
