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, they not only lose their effectiveness, but also become harmful! Vacuum bottles can prevent the contents from contacting the air, effectively reducing the product from deteriorating and breeding bacteria due to contact with the air. It also allows cosmetics manufacturers to reduce the use of preservatives and antibacterial agents, so that consumers can get higher protection.
Product definition
The vacuum bottle is a high-end package composed of an outer cover, a pump set, a bottle body, a large piston inside the bottle and a bottom support. Its launch conforms to the latest development trend of cosmetics and can effectively protect the quality of the contents. However, due to the complex structure of the vacuum bottle and the high production cost, the use of vacuum bottles is limited to individual high-priced and high-requirement products, and it is difficult to fully roll out the vacuum bottle in the market to meet the needs of cosmetic packaging of different grades.
Manufacturing process
1. Design principle
The design principle of the vacuum bottle is based on atmospheric pressure and is highly dependent on the pump output of the pump group. The pump group must have excellent one-way sealing performance to prevent air from flowing back into the bottle, causing a low-pressure state in the bottle. When the pressure 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 fit too tightly against the inner wall of the bottle, otherwise the large piston will not be able to move forward due to excessive friction; on the contrary, if the large piston fits too loosely against the inner wall of the bottle, leakage is likely to occur. Therefore, the vacuum bottle has very high requirements for the professionalism of the production process.
2. Product features
The vacuum bottle also provides precise dosage control. When the diameter, stroke, and elastic force of the pump group are set, no matter what the matching button shape is, each dosage is accurate and quantitative. Moreover, the discharge volume of the press can be adjusted by changing the pump group parts, with an accuracy of up to 0.05 ml, depending on the product requirements.
Once the vacuum bottle is filled, only a tiny amount of air and water can enter the container from the production factory to the consumer's hands, effectively preventing the contents from being contaminated during use and extending the effective use period of the product. In line with the current environmental protection trend and the call to avoid adding preservatives and antibacterial agents, vacuum packaging is even more important for extending the shelf life of products and protecting the rights of consumers.
Product structure
1. Product classification
By structure: ordinary vacuum bottle, single-bottle composite vacuum bottle, double-bottle composite vacuum bottle, non-piston vacuum bottle
By shape: cylindrical, square, cylindrical is the most common
Vacuum bottles are usually cylindrical or oval, with common specifications of 10ml-100ml. The overall capacity is small, relying on the principle of atmospheric pressure, which can avoid contamination of cosmetics during use. Vacuum bottles can be processed with electroplated aluminum, plastic electroplating, spraying, and colored plastics for appearance treatment. The price is more expensive than other ordinary containers, and the minimum order quantity requirement is not high.

3. Structural supporting drawings for reference
The main accessories of vacuum bottles include: pump set, lid, button, outer cover, screw thread, gasket, bottle body, large piston, bottom bracket, etc. The appearance parts can be decorated by electroplating, electroplating aluminum, spraying and silk screen hot stamping, etc., depending on the design requirements. The molds involved in the pump set are more precise, and customers rarely make their own molds. 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-sealing valve vacuum bottle is a vacuum bottle that holds skin care products. The lower end is a bearing disc that can move up and down in the bottle body. There is a round hole at the bottom of the vacuum bottle body. There is air below the disc and skin care products above. The skin care products are sucked out from the top by the pump, and the bearing disc continues to rise. When the skin care products are used up, the disc rises to the top of the bottle body.
Applications
Vacuum bottles are widely used in the cosmetics industry,
mainly suitable for creams, water-based agents,
lotions, and essence-related products.
