Airless Pump Bottle

Airless Pump Bottle refers to a container that can isolate gas from external temperature or isolate external bacteria.

The contents of the airless pump bottles can be completely isolated from the air, so as to prevent the product from being oxidized and deteriorated due to contact with the air, and the breeding of bacteria. It also improves the product level with its high-tech concept. The Airless Bottle prevailing on the market is made up of a cylinder into an ellipsoidal container plus a piston placed at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, resulting in a vacuum state, and to use 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 too tightly attached to the bottle wall, otherwise the piston will not be able to rise and move forward due to excessive resistance; Therefore, vacuum bottles have very high requirements on the professionalism of manufacturers.
