The spray pump, also known as the push-type emulsion pump, is a liquid distributor that uses the principle of atmospheric balance to draw out the raw material liquid in the bottle and replenish the atmosphere inside and outside the bottle. The main performance indicators of the spray pump include air pressure times, pump displacement, low pressure, nozzle opening torque, rebound speed, water intake index, etc.
The spray pump dispenser is divided into sleeve type and screw type, and functionally divided into sprayer, foundation, emulsion pump, aerosol valve and vacuum bottle.
The size of the spray pump is determined by the corresponding diameter of the bottle. The spray specifications are 12.5mm-24mm-24mm, and the water output is 0.1ml/time-0.2ml/time. It is generally used for the packaging of perfume, gel water and other products. . In the case of the same caliber, the handover length can be determined by the height of the bottle.
The specifications of the spray pump range from 16ml to 38ml, and the water output is 0.28ml/time to 3.1ml/time, generally used for cream and washing products.
Special spray pump dispensers such as foam pump heads and hand pump heads. The Foam Spray Pump is a non-pneumatic hand pump that produces quantitative, high-quality foam with only light pressure and no inflation. There are usually special bottles. Snap ring nozzles are commonly used for detergents and other products.
The structure of the spray pump distributor is very complex, generally including dust cover, piston, tapping head, gasket, spring, valve, tapping rod, pump body, cover, suction tube and valve ball (with steel ball and glass ball). Covers and dust caps are available in coloured, galvanised or inlaid anodised aluminium.
The vacuum bottle is usually cylindrical, the specification is 15ml-50ml, each bottle is 100ml, and the overall capacity is small. Relying on the principle of atmospheric pressure, the pollution of cosmetics in use can be avoided. The vacuum bottle is made of electrolytic aluminum, plastic electroplating and colored plastic. The price is higher than other ordinary containers, and the ordinary order volume is not high. Customers rarely open molds by themselves, and they need a lot of molds, which are very expensive.
