Unlike dispensers that usually use pipes or straws to pump the product out, Cream Pump Dispensers's an airless pump bottle is used in conjunction with a vacuum mechanism.

The airless pump bottle is divided into three parts:

Base: There is a small hole in the base to provide power for the vacuum effect and make it possible for air to enter
Plate: There is a plate (or disc) in the bottle, and your skin care products are placed on the plate.
Pump: A vacuum effect is generated by the suction action to extract the product.
With each suction action, the product on the plate (in the bottle) will be pushed upward by the vacuum effect-air enters the hole at the bottom of the bottle, pushing the plate holding the product, and pushing it upward.
