An Airless Pump Bottle is a non-pressurized vacuum dispensing system that utilizes a mechanical pump in a bottle. As you push down on the pump, the disc in the bottle rises to push the product out of the pump. Once the bottle is filled, the material stored inside the bottle is preserved and maintain its integrity until used up. Airless packaging will help increase the shelf life of the final product.
Using a conventional pump bottle, when the content in the bottle gets low the tube in the bottle will no longer be able to pull the products to the pump, so 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 products 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 throughout its use.
