Airless pump bottles cosmetic

The contents of a airless pump bottles cosmetic can be completely isolated from the air, avoiding the oxidation of the product due to exposure to air, causing bacteria to grow, and improving the product file with its high-tech concept. The vacuum flask in the market is composed of a cylinder with an ellipsoidal container and a piston at the bottom.Airless pump bottles cosmetic is designed to use the spring's contraction force without letting air into the bottle, creating a vacuum, and using atmospheric pressure to push the piston forward in the bottom of the bottle. But because the spring force and atmospheric pressure do not give enough force, the piston can't fit too tightly with the wall, otherwise the piston will not be able to rise because of the resistance. On the other hand, if the piston is easy to move forward and easy to leak, the airless pump bottles cosmetic is very high for the professional requirements of the manufacturer.
