When purchasing vacuum bottle containers, you need to understand these basics

Introduction: Many cosmetics on the market contain amino acids, proteins, vitamins and other substances. These substances are very afraid of dust and bacteria and are easily contaminated. Once contaminated, not only will it lose its intended effect, but it will also become harmful! Vacuum bottles can prevent the contents from contacting the air, effectively reducing product deterioration and bacterial growth due to contact with air. It also allows cosmetics manufacturers to reduce the use of preservatives and antibacterial agents, giving consumers higher protection.

Product definition

The vacuum bottle is a highend packaging composed of an outer cap, a pump set, a bottle body, a large piston inside the bottle, and a base. Its launch complies with the latest development trend of cosmetics and can effectively protect the quality of the contents. However, due to the complex structure of vacuum bottles and high production costs, the use of vacuum bottles is limited to a few high-priced and high demand products, making it difficult to fully roll out in the market to meet the needs of different grades of cosmetic pack aging.

Manufacturing Process

1, Design principle

The design principle of the vacuum bottle is based on atmospheric pressure and relies heavily on the pump output of the pump unit. The pump unit must have excellent oneway sealing performance to prevent air from flowing back into the bottle and causing a low pressure state inside the bottle. When the difference between the low pressure area in the bottle and the atmospheric pressure is greater than the friction between the piston and the inner wall of the bottle, the atmospheric pressure will push the large piston in the bottle to move. Therefore, the large piston cannot be too tightly attached to the inner wall of the bottle, otherwise the large piston will be unable to move forward due to excessive friction; conversely, if the large piston is too loosely attached to the inner wall of the bottle, leakage will easily occurso the vacuum bottle has a negative impact on the production process. The professional requirements are very high.

2, Product Features

The vacuum bottle also provides precise dosage control. Once the diameter, stroke, and elasticity of the pump set are set, the dosage will be accurate and quantitative each time regardless of the shape of the matching button. Moreover, the discharge volume of the pump can be adjusted by changing the parts of the pump set, with an accuracy of 0.05 ml, depending on the needs of the product.

Once the vacuum bottle is filled, almost minimal air and moisture can enter the container from the production factory to the end of use in the hands of consumers, effectively preventing the content from being contaminated during use and extending the effective life of the product. In line with the current trend of environmental protection and the call to avoid adding preservatives and antibacterial agents, vacuum packaging is even more important to extend the shelf life of products and protect the rights of informants.

Product Structure

1,Product classification

According to structure: ordinary vacuum bottle, single-bottle composite vacuum bottle, double bottle composite vacuum bottle, non-piston vacuum bottle. According to shape: cylindrical, square, cylindrical is the most common.

Vacuum bottles are usually cylindrical or oval, with common specifications of 10ml-100ml, and a small overall capacity. They rely on the principle of atmospheric pressure to avoid contamination of cosmetics during use. Vacuum bottles can be used with anodized aluminum, plastic plating, spraying, and colored plastics for appearance treatment. The price is more expensive than other ordinary containers, and the minimum order requirementis not high.

3, Reference to structural supporting drawings

The main accessories of the vacuum bottle include: pump set, cap, button, jacket, thread, gasket, bottle body, large piston, bottom bracket, etc. Appearance parts can be decorated, including electroplating, anodized aluminum coating, spray coating, silk screen printing, etc., depending on the design requirements. The molds involved in the pump set are relatively sophisticated, and customers rarely open the molds themselves. The main accessories of the pump set include: small piston, connecting rod, spring, body, valve, etc.

4, Other types of vacuum bottles

The all-plastic self-closing valve vacuum bottle is a vacuum bottle containing skin care products.The lower end of the vacuum bottle is a carrying disc that can move up and down in the bottle body. There is a round hole at the bottom of the vacuum bottle. The bottom of the disc is air and the top is skin care products. The skin care products are sucked out from the top by the pump, and the carrying disc continues to rise. When the skin care productare used up, the disc rises to the top of the bottle.
