The lotion pump is also called a push-type lotion pump. It is a liquid distributor that uses the principle of atmospheric balance to pump out the material liquid in the bottle by pressing and supplement 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 index, etc.

Distributors are divided into two types: barbed type and screw type. From the function point of view, they are divided into spray, foundation cream, lotion pump, aerosol valve, and vacuum bottle.

The size of the pump head is determined by the diameter 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 packaging of perfume, gel water and other products. The same caliber takes over The length can be determined according to the height of the bottle.

Lotion pump head specifications range from 16ml to 38ml, and the water output is 0.28ml / time-3.1ml / time, generally used in creams and washing products.

Special dispensers such as foam pump head and hand-buckle spray head. The foam pump head is a non-inflation type hand pressure pump head. It does not need to be inflated to generate foam. Only a light press can produce quantitative high-quality foam. Generally equipped with special bottles. Hand button spray heads are commonly used in cleaning products and other products.

The composition of the distributor is relatively 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.

Vacuum bottles are usually cylindrical, with specifications of 15ml-50ml, individual 100ml, the overall capacity is small, relying on the principle of atmospheric pressure, to avoid pollution caused by cosmetics during use, vacuum bottles have anodized aluminum, plastic plating and colored plastic, The price is more expensive than other common containers, and the general order quantity is not high. Distributor customers rarely open their own molds, and need more molds to pay for, and the cost is higher.
