An Airless Bottle is a non-pressurized vacuum dispensing system which utilize a mechanical pump in a bottle. Once the bottle is filled, the material stored inside the bottle is preserved and maintain its integrity until used up.
Using a conventional pump bottle, when the content in bottle gets low, the common practice is to remove the pump and try to get the remaining material out with the use of a spatula type of tool. With the repeat opening of the pump and expose the content to air, some product will end up being oxidized and lose its effectiveness.
With the airless bottles, the material inside the bottles will be able to dispense completely which will not require the opening of the pump and therefore the integrity of the content can remain stable all throughout its use.
