In fact, in the face of this problem, we must first know the insulation principle of the vacuum flask, how does the vacuum flask keep it warm?

Generally speaking, a vacuum flask with a large capacity and a small mouth will have a longer holding time, while a vacuum flask with a small capacity and a large mouth will have a relatively shorter holding time.

Insulation cups with good insulation effect are generally double-layered cups and are made through a vacuum process. The purpose of this is to evacuate the air between the double layers of the cup material, so that the heat loss of the cup will be reduced to a lower level, resulting in an excellent thermal insulation effect. Generally speaking, the material of the vacuum flask is stainless steel, and only the vacuum-treated cup can be called a vacuum cup!
