The contents of the cosmetic airless bottle can be completely isolated from the air, preventing the product from being oxidized and deteriorating due to contact with the air, breeding bacteria, and improving the product quality with its high-tech concept. The vacuum bottle commonly used in the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom.

Its design principle is to use the contraction force of the spring to prevent the air from entering the bottle, resulting in a vacuum state, and to use the atmospheric pressure to push the piston at the bottom of the bottle forward. However, since the spring force and atmospheric pressure cannot give enough force, the piston cannot fit too tightly with the bottle wall, otherwise the piston will not be able to rise and move forward due to excessive resistance. Therefore, the vacuum bottle has very high requirements for the professionalism of the manufacturer.

The modern thermos was invented in 1892 by British physicist Sir James Dewar. At that time, he was conducting a research work on liquefying gas. To liquefy gas at low temperature, he first needed to design a container that could isolate the gas from the outside temperature. So he asked glass technician Berg to blow a double-layered glass for him. Glass container with two layers coated with mercury.

The air between the two layers is then evacuated, creating a vacuum. This kind of vacuum bottle is also called "Du bottle", which can keep the liquid contained in it unchanged for a certain period of time, regardless of the temperature or temperature.

Because the thermos bottle is mainly used for hot water insulation in the family, it is also called the thermos. The construction of the thermos is not complicated. The middle is a double-layer glass bottle, and the two layers are evacuated and plated with silver or aluminum. The vacuum state can avoid thermal convection.

Glass itself is a poor conductor of heat, and silver-coated glass reflects back heat radiated from the interior of the container. In turn, if the bottle stores cold liquid, the bottle can prevent the external heat from radiating into the bottle.
