What is an airless pump bottle

Airless pump bottle refers to a container that can isolate the air from the outside 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 design.

The airless pump bottle commonly used in the market is composed of a cylindrical or ellipsoid container with 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 to create 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 attached to the bottle wall too tightly, 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, airless dispenser bottles have very high requirements on the professionalism of manufacturers, and not all manufacturers can produce airless pump bottles.

How we benefit from airless pump bottle

Cosmetic airless bottle prevents sensitive products (such as natural skin creams, serums, foundations and other paraben-free formulas) from being exposed to the air, thereby protecting their lifespan by up to 15 %. Also, through the physics of squeezing air, no residue is left inside the bottle. So is it worth having a airless pump bottle that can prevent bacteria from contacting the emulsion, preserve freshness and prolong the freshness of the product?
