How To Use The Vacuum Bottle For Dispensing Cosmetics

When the cosmetic vacuum bottle is in use, press and hold the top, and the piston at the bottom will run up to squeeze the contents out. When the contents of the bottle are used up, the piston will go to the top. When the piston tops to the bottom, the vacuum bottle can be removed. The pump head and other parts can be removed and re-installed, and it can be used repeatedly.

The vacuum bottle uses the contraction force of the spring to prevent the outside air from entering the vacuum bottle. Atmospheric pressure is used to push the piston at the bottom of the bottle forward. The contents of the vacuum bottle can be completely isolated from the air, preventing the product from oxidative deterioration and breeding bacteria due to contact with the air, and enhances 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, due to the spring force and atmospheric pressure, sufficient force cannot be given.

Therefore, 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; on the contrary, if the piston is to be easy to move forward and material leakage is likely to occur, the vacuum bottle requires very high professionalism from the manufacturer .
