There may be many people who have seen airless bottles but do not know how to use them. Some people may also ask whether the airless bottle can be used repeatedly, which is actually possible.
1. The airless bottle is a container for cosmetic packaging, which refers to a container that can isolate gas from the outside temperature, and a container that isolates external bacteria.
2. The contents of the airless bottle can be completely isolated from the outside world. Avoid products that are oxidized and breed bacteria due to contact with air, which may cause skin infections.
3. When the airless bottle is pressed, the bottom piston will run up, squeezing the contents out. When the contents of the bottle are used up, the piston will go to the top.
4. When the bottom piston reaches the top, you can push the piston to the bottom. A small hole on the bottom can adjust the altitude of the piston.
