The working principle of cosmetic airless bottles

Recently, many brands have successively used cosmetic airless bottle packaging. Following are the brief description of the working principle and function of cosmetic airless bottles.


What is a cosmetic airless bottle

  cosmetic airless bottle

Cosmetic airless bottle refers to a container that can isolate the gas from the external temperature or a container that isolates external bacteria. Its contents 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 grade with its high-tech concept.


How cosmetic airless bottles work

The popular cosmetic airless bottle on 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 be attached too tightly to 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, Therefore, cosmetic airless bottles have very high requirements for the professionalism of manufacturers.


Function of cosmetic airless bottles

The launch of cosmetic airless bottles conforms to the latest development trend of skin care products, which can effectively protect the freshness and quality of products.However, due to the complex structure and high cost of the airless bottle, the use of airless bottle packaging is limited to a few categories of products and cannot be fully spread in the market to meet the needs of different grades of skin care products packaging.
