Hou, innovative airless bottles consist of a bottle container, a plastic piston apparatus inside a diaphragm in the body, and a pump head at the mouth of the bottle. When the pump is depressed, the piston moves upward inside the diaphragm.
Pressure works to fill the empty cavity and then dispenses the contents uniformly. When your customers are using small quantities, the precision afforded by airless pumps can be extremely important, especially for treatment products that require a higher level of accuracy.
