How Does Perfume Atomizer Form Vacuum State

  •  


    Perfume Atomizer is one of the main packaging materials in cosmetics. The popular perfume atomizer in the market consists of an ellipsoidal container with a piston at the bottom. Its design principle is to use the contraction force of spring and prevent air from entering the bottle, thus creating a vacuum state, while using atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure can not give enough force, the piston can not be attached to the bottle wall too tightly, otherwise the piston will not rise and move forward because of excessive resistance; On the contrary, if the piston is easy to move forward and leakage occurs easily, the perfume atomizer has very high professional requirements for manufacturers.
