Buying lotion pumps, these basic knowledge should be understood

Introduction: Whether it is a plastic bottle or a glass container, how to effectively take out their contents requires a tool component that matches the container. The lotion pump is such a matching tool. It can be said that it is the most important component in the cosmetic container. The way to take out the contents also directly determines the consumer's experience and satisfaction with the product. In this article, we mainly introduce the lotion pump product, and the content is only for reference by purchasing friends:

Pump head definition

The lotion pump is a major tool for taking out the contents of cosmetic containers. It is a liquid dispenser that uses the principle of atmospheric balance to pump out the liquid in the bottle by pressing and replenish the outside atmosphere into the bottle.

Product structure and manufacturing process

1. Structural components

Regular lotion heads are usually composed of a nozzle/head, upper pump column, lock cap, gasket, bottle cap, pump plug, lower pump column, spring, pump body, glass ball, straw and other accessories. Depending on the structural design requirements of different pumps, the related accessories will be different, but the principle andultimate purpose are the same, that is, to effectively remove the contents.

2. Production process

Most of the pump head accessories are 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 from outside. The main components of the pump head can be applied to electroplating, electroplated aluminum cover, spraying, injection molding, etc. The surface of the nozzle and the surface of the braces of the pump head can be printed with graphics and texts, and can be processed by printing processes such as hot stamping/silver, silk screen printing, and pad printing.

Pump head structure description

1. Product classification

Regular diameters: Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, Ф38, etc. According to the lock head: guide block lock head, thread lock head, clip lock head, no lock head According to the structure: spring external pump, plastic spring, water-proof emulsion pump, high viscosity material pump According to the pumping method: vacuum bottle and straw type According to the 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 pressure handle downward, the volume in the spring cavity decreases, the pressure increases, the liquid enters the nozzle cavity through the hole of the valve core, and then sprays out through the nozzle. At this time, release the pressure handle, the volume in the spring cavity increases, forming a negative pressure. The ball opens under the action of negative pressure, and the liquid in the bottle enters the spring cavity. At this time, a certain amount of liquid has been stored in the valve body. When the handle is pressed again, the liquid stored in the valve body will rush upward and spray out through the nozzle.

3. Performance indicators

The main performance indicators of the pump: air compression times, pump output, downward pressure, pump head opening torque, rebound speed, water inlet index, etc.

4. The difference between internal spring and external spring

The external spring does not contact the contents and will not cause the contents to be contaminated by spring rust.

Pump head purchase precautions

1. Product Application

Pump heads are widely used in the cosmetics industry, in the fields of skin care, washing, and perfume, such as shampoo, shower gel, lotion, essence, sunscreen, BB cream, liquid foundation, facial cleanser, hand soap and other product categories.

2. Purchase considerations

Supplier selection: Choose an experienced and reputable pump head supplier to ensure that the supplier can provide pump heads that meet quality standards and product requirements.

Product adaptability: Ensure that the pump head packaging material matches the cosmetic container, including caliber size, sealing performance, etc., to ensure that the pump head can work properly and prevent leakage.

Supply chain stability: Understand the supplier's production capacity and delivery capacity to ensure that the pump head packaging material can be supplied on time to avoid production delays and inventory backlogs

3. Cost structure:

Material cost: The material cost of pump head packaging usually accounts for a considerable proportion, including plastic, rubber, stainless steel and other materials.

Manufacturing cost: The manufacturing of pump heads includes mold manufacturing, injection molding, assembly and other links, and manufacturing costs such as labor, equipment and energy consumption need to be considered.

Packaging and transportation costs: The cost of packaging and transporting the pump head to the terminal, including packaging materials, labor and logistics costs.

4. Key points of quality control:

Raw material quality: Ensure that high-quality raw materials that meet the requirements are purchased, such as the physical properties of plastics, chemical resistance, etc.

Mold and manufacturing process control: Strictly control the mold size and structure to ensure that the pump head manufacturing process meets the technical requirements.

Product testing and verification: Perform necessary functional tests on the pump head, such as pressure testing, sealing testing, etc., to ensure that the performance of the pump head meets the requirements.

Process control and quality management system: Establish a complete production process control and quality management system to ensure the stable quality and consistency of the pump head.
