The lotion pump, also known as the push-type lotion pump, is a liquid dispenser that uses the principle of atmospheric balance to pump out the liquid in the bottle by pressing and replenishing the external atmosphere into the bottle. The main performance indicators of the lotion pump are the number of air pressures, the pump output, the down pressure, the opening torque of the pressing head, the rebound speed, and the water intake index.

    The dispenser is divided into two types: tie type and screw type. In terms of function, it is divided into spray, foundation cream, lotion pump, and aerosol valve. The size of the pump head of the vacuum bottle is determined by the diameter of the matching bottle body. The specifications of the spray are 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time, generally used for perfume, gel water, and another product packaging. The length of the nozzle with the same diameter can be determined according to the height of the bottle. The specifications of the lotion pump head range from 16ml to 38ml, and the water output is 0.28ml/time to 3.1ml/time. It is generally used for creams and washing products.​​

    Special dispensers such as foam pump heads and hand button sprinkler heads, the foam pump head is a kind of non-air-filled hand pressure pump head, which does not need to be filled with air to generate foam, and can produce quantitative high-quality foam only by pressing lightly. Usually comes with a dedicated bottle. Hand-on applicators are often used on products such as cleaners.
