What is the difference between a thermos flask and a vacuum flask?

Insulated bottles and vacuum bottles are the same type of product, with the same framework and principle. The traditional inner wall of early vacuum bottles was made of glass. With the passage of time, advances in science and technology, and product innovation, most thermos bottles are made of stainless steel. Vacuum bottles inside glass are becoming increasingly scarce.

In fact, the functions of various vacuum bottles are almost the same. They are all vacuum structures that can maintain the temperature of the components for a longer period of time. It can accommodate both cold and hot drinks.

What is a thermos bottle?

A thermos is a container that can keep liquids refrigerated or heated for hours or even a whole day. They are made of stainless steel, heat-resistant glass, or plastic. This design can prevent condensation inside the flask and allow for gradual temperature changes. Insulated bottles usually have a lid with a sealing gasket, which makes it easier to open the container.

Vacuum insulation

A vacuum bottle can hold hot or cold water or firewood for several hours. This occurs due to the vacuum effect of the double walls. The inner and outer walls of the bottle consist of two layers, with a space between them to expel air. This reduces the possibility of heat loss. In other words, it can help you avoid transmission.
