The lotion(emulsion) pump is a kind of supporting tool to take out the contents in the cosmetic container, it is a kind of liquid dispenser that utilizes the principle of atmospheric balance, pumps out the material liquid in the bottle by pressing, and replenishes the outside atmosphere into the bottle.
1、Structural components
Conventional emulsion head often consists of push nozzle/push head, upper pumping column, locking cap, gasket, bottle cap, pump stopper, lower pumping column, spring, pump body, glass ball, suction tube and other accessories. According to the structural design requirements of different pumps, the relevant accessories will be different, but the principle and the ultimate purpose are the same, that is, to effectively remove the contents.
2、Production process
Most of the accessories of the pump head are mainly made of PE, PP, LDPE and other plastic materials through injection molding. Among them, glass beads, springs, gaskets and other accessories are usually purchased externally. The main components of the pump head can be applied to electroplating, electrified aluminum cover, spraying, injection molding color and other ways. The pump head can be graphically printed on both the surface of the presser nozzle and the surface of the bushing, which can be processed by utilizing printing processes such as hot stamping/silvering, silk-screen printing, pad printing, and so on.
Second, the product structure
1、Product classification
Conventional diameter: Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, Ф38 and so on.
According to the lock: guide block lock, threaded lock, card lock, no lock
According to the structure: spring external pump, plastic spring, anti-water emulsion pump, high viscous material pumps
According to the pumping method: vacuum bottle and suction tube type
Pumping volume: 0.15/ 0.2cc, 0.5/ 0.7cc, 1.0/2.0cc, 3.5cc, 5.0cc, 10cc and above.
2、Working Principle
Manually press the handle down, the volume in the spring chamber decreases, the pressure rises, the liquid through the hole in the valve core into the nozzle chamber, and then through the nozzle to spray the liquid outward, then release the handle, the volume in the spring chamber increases, the formation of negative pressure, the ball opens under the action of negative pressure, the liquid in the bottle enters the spring chamber, the valve body has been stored in a good certain amount of liquid, when the handle is pressed again when the liquid stored in the valve body will be rushed upward, through the nozzle to spray outward. When the handle is pressed again, the liquid stored in the valve body will rush upward and spray outward through the nozzle;
3、Performance indicators
The main performance indicators of the pump: the number of times of empty pressure, pumping volume, lower pressure, pressure head opening torque, rebound speed, water intake indicators.
4, the difference between the built-in spring and external spring
External spring, which does not contact the contents, will not cause contamination of the contents due to spring rust.
Lotion Pumps are widely used in the cosmetic industry, in the field of skincare and toiletries, perfumery, such as shampoo, body lotion, moisturizer, serum, sun screen, BB cream, foundation, face wash, hand sanitizer and other product categories are used.
