Understanding lotion pump

It is also called a push-type lotion pump. It is a liquid dispenser that uses the principle of atmospheric balance to pump out the material and liquid in the bottle by pressing and replenish the outside atmosphere into the bottle. The main performance indicators of the lotion pump: air pressure times, pump output, down pressure, head opening torque, rebound speed, water intake indicators, etc.
Distributors are divided into two types: tie-type and screw-type. In terms of function, they are divided into spray, foundation cream, lotion pump, aerosol valve, and airless bottle.

The size of the pump head is determined by the caliber of the matching bottle. The spray specification is 12.5mm-24mm, and the water output is 0.1ml/time—0.2ml/time. It is generally used for perfume, gel water and other product packaging. The length of the bottle can be determined according to the height of the bottle.

The lotion pump head has a wide range of 16ml to 38ml, with a water output of 0.28ml/time-3.1ml/time, and is generally used for creams and washing products.

Special dispensers such as foam pump heads and hand-button sprinklers. Foam pump heads are non-air-filled hand-pressure pump heads that do not need to be filled to produce foam, and can produce quantitative high-quality foam with light pressure. Usually comes with a dedicated bottle. Hand-button sprinklers are usually used in products such as detergents.

The composition of the dispenser is more complicated, generally including: dust cover, snap head, snap rod, gasket, piston, spring, valve, bottle cap, pump body, straw, valve ball (with steel ball, glass ball). Bottle caps and dust caps can be colored, electroplated, and can be covered with anodized aluminum rings.

Airless bottles are usually cylindrical, with specifications ranging from 15ml to 50ml, and some have 100ml. The overall capacity is small. It relies on the principle of atmospheric pressure to avoid pollution caused by cosmetics during use. Airless bottles include anodized aluminum, plastic plating, and colored plastics. The price is more expensive than other general containers, and the general order quantity requirement is not high. Distributor customers seldom open molds by themselves, and they need more molds, and the cost is higher.
