Cosmetic Pump Head Analysis And Inspection Standards

Cosmetic Pump Head Analysis And Inspection Standards

Today I mainly talk to you about the difference between the external pump and the built-in pump involved in the nozzle and pump head that we often talk about.

External pump: For nozzles and pump heads, everyone should know that springs need to be placed inside the product center. The external pump, that is, the spring in the center of the nozzle/pump head is visible from the outside, and is usually placed on the Above the pump core, the assembly is directly connected to the nozzle/pump head cap. The advantage of the external pump is that it does not come into direct contact with the liquid in the bottle, which is environmentally friendly and hygienic, and can avoid rust on individual springs and affect the quality of the product in the bottle. Of course, this problem is rare, because most of the springs are passed through processed. In addition, the power of the external pump is greater than that of the built-in pump, so the general pump head uses more external pumps, which are suitable for relatively viscous liquids such as emulsion stock solutions.

Built-in pump: Opposite to the external pump, the built-in pump, that is, the spring in the center of the nozzle/pump head is built-in and invisible, and is generally located in the middle of the pump body. The internal spring can directly contact the liquid, and the pressure channel is relative to the external The pump is slightly smaller, and is generally used for health care products such as essential oils, perfumes, and skin care water, which are closer to water.

What are the inspection standards for cosmetic pump heads?

1. Quality Standards

The pump body of the pump head must ensure integrity. There is no crack or deformation, the pump mouth and the bottle mouth should maintain complete tightness, the part of the pump head exposed to the bottle body should have a smooth surface, no bubbles, no spots, no scratches, no burrs, and the pump head with a lock should be locked state.

2. Appearance

The outer packaging should be clean and tidy, without any stains. The color of the pump head should be consistent with the bottle body. The color that meets the requirements should not be different. The tube of the pump head should be kept unobstructed.

Regardless of the quality, appearance or other aspects of the pump head, there must be a qualified quality inspection certificate from the corresponding manufacturer to prove that the inspection of the cosmetic pump head has passed the standard before it can be put into use.
