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, aerosol valve, and vacuum bottle.
The size of the pump head is determined by the diameter of the matching bottle body, and the length of the nozzle with the same diameter can be determined according to the height of the bottle body. Lotion pumps have a wide range of specifications and are generally used for creams and washing products. Special dispensers such as foam pump head and hand button sprinkler head, foam pump head is a kind of non-air-filled hand-pressure pump head, which does not need to be filled 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.
The composition of the distributor is relatively complex, generally including: dust cover, pressing head, pressing rod, gasket, piston, spring, valve, bottle cap, pump body, straw, valve ball (steel ball, glass ball). Bottle caps and dust caps can be colored, electroplated, or covered with anodized aluminum rings.
- The vacuum bottle is usually cylindrical, with a specification of 15ml-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. The vacuum bottle has anodized aluminum, plastic electroplating and colored plastics. The price is more expensive than other ordinary containers.
