Composition principle of foam pump head on cosmetic bottle dispenser
1. The dispenser is divided into two types, i.e. binding type and screw type. Functionally, it is divided into spray, foundation cream, lotion pump, aerosol valve and vacuum bottle.
2. The size of the plastic pump head is determined by the caliber of the matching bottle body. The standard of spray is 12.5-24mm, and the water output is 0.1-0.2ml/time. It is generally used on the packaging of perfume, gel water and other commodities. The receiving length with the same caliber can be determined according to the height of the bottle body.
3. The standard scale of lotion pump head is 16-38ml, and the water output is 0.28-3.1ml/time. It is generally used for cream and washing products.
4. Special dispensers such as foam pump head and hand button nozzle. The foam pump head is a non air filled hand pressure pump head, which does not need to be filled with air to generate foam. It can generate quantitative high-quality foam only by pressing lightly. Special bottles are usually provided. The hand button type nozzle is generally used for cleaning agents and other commodities.
5. The vacuum bottle is generally cylindrical, with a standard of 15-50ml and a single volume of 100ml. The overall capacity is small. It relies on the principle of atmospheric pressure, which can prevent the pollution of cosmetics in the process of use. There are electrochemical aluminum, plastic electroplating and colored plastics.
