Lotion Pump
It is a special tool for extracting contents in cosmetic packaging. It is designed based on the principle of atmospheric balance. It extracts the liquid in the bottle by applying pressure, and allows the outside air to enter the bottle to achieve the liquid distribution function.
1. The structure of the lotion pump head usually consists of a pressing head, an upper pump column, a locking cover, a gasket, a bottle cap, a pump core, a lower pump column, a spring, a pump body, a glass ball, and a straw. The surface treatment of the lotion pump head can be electroplated, anodized aluminum cover, spraying, injection molding and other methods.
2. The classification of lotion pump heads is subdivided according to the diameter size, lock type, structure type (such as spring external pump, plastic spring pump, etc.), pumping method (vacuum bottle and straw type) and pumping volume (such as 0.15/0.2cc, 0.5/0.7cc and other specifications). Its main performance indicators include air compression times, pumping volume, down force, opening torque, rebound speed and waterproof performance.
3. The external spring design avoids direct contact with the contents, effectively preventing the contamination of the contents caused by rusting of the spring. Lotion pumps are widely used in the cosmetics industry. They are not only suitable for skin care and cleaning products, such as shampoo and shower gel, but also widely used in essences, sunscreens, BB creams, foundation liquids, facial cleansers, hand sanitizers and other cosmetics.
