What is an airless pump bottle of Cream Pump Dispensers?
As the name suggests, these lightweight, leak-proof bottles are designed to eliminate air from entering the packaging.

When the user presses on the pump itself, the movement initiates a vacuum effect. The air inside the bottle is pumped out together with the product (e.g. lotion, serum, cream).

Pushing from the bottom is a plastic plate located under the product. This plate replaces the traditional dip tube found in most standard lotion pumps.

Therefore, the product is pulled up by the pump and pushed up by the diaphragm below. Then, air refills under the plastic plate to rebalance the bottle. For this reason, you will notice a small hole at the bottom of these bottles that allows air to enter from below.
