Composition Principle of Cosmetic Pump Head

Composition Principle of Foam Pump Head on Cosmetic Bottle Dispenser.

1. Dispensers are divided into two types, i.e. pierced type and screw type. Functionally, they are also divided into spray, foundation cream, emulsion pump, aerosol valve and vacuum bottle.

2. The size of the pump head is determined by the caliber of the matching bottle body. The spray size is 12.5mm—24mm-24 mm, and the water yield is 0.1ml/ time-0.2 ml/time. It is generally used for packaging perfume, gel water and other products. The length of the connecting pipe with the same caliber can be determined according to the height of the bottle body.

3. The emulsion pump has a larger specification range of 16ml to 38ml and a water yield of 0.28ml/ time-3.1 mL/time. It is generally used for cream and washing products.

4. Special dispensers such as foam pump head and hand-held nozzle. Foam pump head is a non-pneumatic hand-held pump head, which does not need to be filled with air to generate foam, and only needs light pressing to generate quantitative high-quality foam. Generally, there are special bottles. Hand-held sprinklers are usually used on products such as detergents.

5. The composition of the distributor is relatively complex, generally including: dust cover, press head, press rod, gasket, piston, spring, valve, bottle cap, pump body, suction pipe, valve ball (steel ball, glass ball). It can be colored, electroplated, and covered with anodized aluminum rings.

6. Vacuum bottles are usually cylindrical in shape, with specifications ranging from 15 mL to 50 mL, with 100ml in each case. The overall capacity is relatively small. The principle of atmospheric pressure is used to prevent cosmetics from causing pollution during use.

Detecting whether the thickness of the piston is attached to the body

Why can’t lotion pump rebound after pressing?

In order to avoid this kind of situation, in the production process, we should check the following points:

First, check whether the spring length is standard.

The difference is very small, and the effect of length on the piston cannot be ignored. If it is short, it will cause the piston to miss its return stroke, directly causing the piston to not rebound or rebound slowly after pressing down the head.

Secondly, check whether the thickness of the piston fits the body.

In the movement of the piston, any slight gap will result in weak suction and unable to press the discharge body. Because plastic has the property of expanding with heat and contracting with cold, normal piston is very important to ensure the quality of emulsion pump.

Finally, let’s analyze ontology.

Due to the stretchability of plastic, if improper operation is done during injection molding, insufficient injection will cut off a thin layer of the body, resulting in uneven inner wall, and inevitably leaving gaps in the piston stamping process, resulting in no discharge.

The waterproof capability of the hose cover is relatively strong

The development speed of cosmetic covers has exceeded people’s imagination. In our daily life, we can see the application of hose covers everywhere, such as shampoo, cosmetics, detergent, etc. We can see the effect of hose covers in our daily life.

From simple plastic round caps to diversified spray pumps and hose caps, this process changes according to people’s overall needs. Round caps are not as leak-proof as hose caps for cosmetics.

The hose cover can prevent water outside from directly entering the bottle. For the storage of cosmetics, the hose cover can better prevent water outside and bacteria from entering the cosmetics. But also has excellent gas barrier performance, can effectively prevent the infiltration of oxygen and peculiar smell gas, and simultaneously prevent the exudation of fragrance of contents and effective components.

Therefore, the waterproof capability of the hose cover is relatively strong, and it can also directly improve the grade of cosmetic packaging and the use experience of users.

Foam pump can save a certain amount of time and water

Gently press the plastic head on the top of the hand sanitizer bottle to eject foam instead of liquid-this foam design is in vogue.

Because compared with the liquid design, the time people spend washing their hands and the amount of water they consume can be reduced by about 1/3.

This kind of plastic head is called foam pump. Ningbo KeXon Plastic Co., Ltd is a well-known foam pump manufacturer in China. it can spray bath lotion and shampoo in foam form, breaking the monopoly of Japanese enterprises.

The main application of foam pump: washing products (hand sanitizer, shampoo, shower gel, disinfectant, etc.), bio-medicine, cosmetic bags, cosmetics, chemical and other industries.

KeXon Plastic has a highly skilled and experienced research and development team, which has long been committed to independent research and development of new products. It can also customize various types of cosmetic packaging and daily packaging according to customer requirements.

Main Performance Indexes of lotion Pump

Lotion Pump is also called pressing lotion pump. It is a liquid distributor that uses the principle of atmospheric balance to pump out the material liquid in the bottle by pressing and replenish the outside atmosphere into the bottle.

Main performance indexes of lotion pump: air pressure times, pump output, down force, head opening torque, rebound speed, water intake index, etc.

When the pressing handle is pressed down manually, the volume in the spring chamber decreases and the pressure increases. The liquid enters the nozzle chamber through the hole of the valve core and then ejects the liquid out through the nozzle. When the pressing handle is released, the volume in the spring chamber increases and negative pressure is formed. The ball is opened under the negative pressure, and the liquid in the bottle enters the spring chamber. At this time, a certain amount of liquid is already stored in the valve body. When the handle is pressed again, the liquid stored in the valve body will be flushed upward and sprayed out through the nozzle.

Judging from the above working principle, the key to a good pump head is to pay special attention to the following areas:

1. Glass beads or steel balls under the spring.

2. Look at the sealing ring at the upper end of the valve body.

3. The matching of the pressing handle and the valve core.

4. The design of the nozzle depends on the atomization effect.

Therefore, the function of the general pump head also detects these four positions, and other appearance and coordination problems are detected conventionally.
