The vacuum insulated flask is generally a water container made of stainless steel and a vacuum layer, with a lid on the top and a tight seal. The vacuum insulation layer can delay the heat dissipation of liquids inside to achieve the purpose of heat preservation.


The stainless-steel vacuum flask is developed from the thermos. The principle of insulation is the same as the thermos, except that people make the bottle into a cup for convenience. There are three ways of heat transmission including radiation, convection and transmission. The silver cup inside the thermos can reflect the radiation of hot water, the vacuum of the cup and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection.
