What is a lotion pump? How does it work? - Maypak

   Product Definition:   

Plastic Pump ( Lotion Pump / Treatment Pump)is the main type of cosmetic container

An accessory tool for removing the contents,

It is a method that uses the principle of atmospheric balance,

Pump out the liquid in the bottle by pressing,

A liquid dispenser that fills the bottle with outside air.

    Manufacturing Process:   

1. Structural components:

Conventional Plastic Pumps ( Lotion Pump / Treatment Pump)are often composed of nozzles/heads, upper pump columns, lock caps, gaskets, bottle caps, pump plugs, lower pump columns, springs, pump bodies, glass balls, straws and other accessories. According to the structural design requirements of different pumps, the relevant accessories will be different, but the principle is consistent with the ultimate purpose, that is, to effectively remove the contents.

2. Production process:

Most of the Plastic Pump accessories are mainly made of plastic materials such as PE, PP, LDPE, etc., and are molded by injection molding. Among them, glass beads, springs, gaskets and other accessories are generally purchased outside. The main components of the pump can be applied to electroplating, anodized aluminum cover, spray coating, injection molding color and other methods. Both the surface of the pump nozzle and the surface of the braces can be printed with graphics and text, and can be processed by printing processes such as bronzing/silver printing, silk screen printing, and pad printing.

    Product Structure:    

1. Product classification:

Conventional diameter: Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, Ф38, etc.;

According to the lock: guide block lock, thread lock, clip lock, no lock;

According to the structure: spring external pump, plastic spring, anti-water emulsion pump, high viscosity material pump ;

According to the pumping method: vacuum bottle and straw type ;

According to pump output: 0.15/ 0.2cc, 0.5/ 0.7cc, 1.0/2.0cc, 3.5cc, 5.0cc, 10cc and above;

2. Working principle:

Manually press down the pressure handle, the volume in the spring chamber decreases, the pressure rises, the liquid enters the nozzle chamber through the hole of the valve core, and then sprays out the liquid through the nozzle, at this time release the pressure handle, the pressure in the spring chamber The volume increases, forming a negative pressure, the ball opens under the negative pressure, the liquid in the bottle enters the spring chamber, at this time there is a certain amount of liquid in the valve body, when the handle is pressed again, the liquid stored in the valve body will be released Rush upwards and spray out through the nozzle;

3. Performance indicators:   

The main performance indicators of the Plastic Pump: air pressure times, pump output, downforce, pressure head opening torque, rebound speed, water intake indicators, etc.

4. The difference between inner spring and outer spring:

External spring, it does not touch the content, and will not cause contamination of the content due to spring embroidery.

   Cosmetic Application:   

Plastic Pumps ( Lotion Pump / Treatment Pump)are widely used in the cosmetic industry

It has applications in the fields of skin care, washing and perfume,

Such as shampoo, shower gel, body lotion, essence, sun protection milk,

BB cream, liquid foundation, facial cleanser, hand sanitizer, etc.

Product categories have applications.

   Key Point:   

1. Liquid effect:

The glass ball or steel ball under the spring, the seal here is very important, it is related to the strength of the liquid in the spring cavity, if there is leakage here, when the pressure handle is pressed, part of the liquid will leak into the bottle and affect In addition, if the sealing ring on the upper end of the valve body leaks here, when the pressure handle is released, the upward pumping force of the liquid will be reduced, resulting in a small amount of liquid stored in the valve body, which will also affect the pumping effect;

2. The cooperation between the pressure handle and the valve core:

If the fit here is loose and there is leakage, there will be a certain resistance when the liquid rushes up to the nozzle, and the liquid will flow back. If there is leakage here, it will also affect the spray effect;

3. Nozzle design:

The design of the Actuator is directly related to the effect of the liquid.

4. Mold cost:

Due to the large number of Plastic Pump components, the cost of mold opening is high.
