What is the principle of vacuum bottle?

At present, people's requirements for bottle caps are getting higher and higher, and the sealing performance of vacuum bottle caps is good. Now the vacuum bottle has become an indispensable preservation item in people's life, especially for the preservation of cosmetics and food. We need to have a good understanding of the vacuum bottle, so that we can achieve good results in the process of use.

Vacuum bottles usually have an oval-shaped container with a freely moving piston at the bottom of the bottle. This is achieved by using the elasticity of the spring to draw air from the bottle, thus keeping the bottle in a vacuum state. In the state, we can use the pressure to move the piston, so as to keep the bottle in the best condition.

Because many cosmetics contain substances that are susceptible to infection, it is necessary to use a vacuum bottle in time to isolate the contents of the bottle from the air. These cosmetics usually contain amino acids, hyaluronic acid, etc., so you must pay attention to keeping them clean. If they are polluted, they will produce substances that are harmful to the human body. The content of the vacuum bottle is not easy to react with the air and lose its due effect, and the good effect of using the vacuum bottle will appear.

The rapid development of vacuum bottles allows cosmetic manufacturers to produce pure natural cosmetics and ensure the quality of cosmetics. The whole vacuum bottle is integrated, which can not only ensure the true vacuum degree, but also simplify the use of parts, save resources, and be particularly easy to recycle.
