Whether it is a plastic bottle or a glass container, if you want to effectively take out the contents, you must have matching tool components. The lotion pump is such a matching tool. It can be said that this is the most important component in a cosmetic container. The way the content is taken out also directly determines the consumer's experience satisfaction with the product. Today we will briefly introduce the product of lotion pump.
The lotion pump is also called the press type lotion pump. It is a kind of liquid dispenser that uses the principle of atmospheric balance to pump out the material and liquid in the bottle by pressing and fill the outside atmosphere into the bottle. The main performance indicators of the lotion pump are: air pressure times, pump output, down pressure, push head opening torque, rebound speed, water intake indicators, etc.
Distributors are divided into two types: tie-type and screw-type. In terms of function, they are divided into spray, foundation cream, lotion pump, aerosol valve, vacuum bottle, and the size of the pump head is determined by the caliber of the bottle. The specification is 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time.
It is generally used for packaging perfumes, gel water and other products. The length of the nozzle with the same diameter can be determined according to the height of the bottle. The lotion pump head has a wide range of 16ml to 38ml, with a water output of 0.28ml/time-3.1ml/time, and is generally used for creams and washing products.
Special dispensers such as foam pump heads and hand-button sprinklers. The foam pump head is a non-gas-filled hand-pressure pump head. It does not need to be filled to produce foam. It can produce quantitative high-quality foam with light pressure. Usually comes with a dedicated bottle. Hand-button sprinklers are usually used in products such as detergents.
The composition of the dispenser is more complicated, generally including: dust cover, snap head, snap rod, gasket, piston, spring, valve, bottle cap, pump body, straw, valve ball (with steel ball, glass ball). Bottle caps and dust caps can be colored, electroplated, and can be covered with anodized aluminum rings.
Airless bottles are usually cylindrical, with specifications ranging from 15ml to 50ml, and some have 100ml. The overall capacity is small. It relies on the principle of atmospheric pressure to avoid pollution caused by cosmetics during use. Airless bottles have anodized aluminum, plastic plating and colored plastics. The price is more expensive than other general containers, and the general order quantity requirement is not high. Distributor customers seldom open molds by themselves, they need more molds, and the cost is higher.
The main accessories are press nozzle/press head, upper pump column, lock cap, gasket, bottle cap, pump plug, lower pump column, spring, pump body, glass ball, straw, etc.
1. 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, part of the liquid will leak into the bottle when the pressure handle is pressed. And affect the effect of liquid spray;
2. The sealing ring at the upper end of the valve body, if there is leakage, the liquid pumping force will decrease when the pressure handle is released, resulting in a small amount of liquid stored in the valve body, which will also affect the spray effect;
3. The fit between the pressure handle and the valve core. If the fit here is loose and leaks, there will be a certain resistance when the liquid rushes up to the nozzle, and the liquid will flow back. If there is leakage, it will also affect the spray effect;
4. The design of the nozzle is directly related to the spray effect.
When purchasing, pay attention to: the pumping effect, the fit between the pressure handle and the valve core, the design of the nozzle, etc., which are related to the spray effect and the required cost.
