home / news / industry news / What are the functions of vacuum bottlesThe contents of the vacuum bottle can be completely isolated from the air, preventing the product from oxidative deterioration and breeding bacteria due to contact with the air, and enhances the product quality with its high-tech concept. The vacuum bottle commonly used in the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom.
Its design principle is to use the contraction force of the spring to prevent air from entering the bottle to create a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, since the spring force and atmospheric pressure cannot give enough force, the piston cannot be attached too tightly to the bottle wall, otherwise the piston will not be able to rise and move forward due to excessive resistance; Therefore, the vacuum bottle has very high requirements for the professionalism of the manufacturer.
The launch of the vacuum bottle conforms to the latest development trend of skin care products, which can effectively protect the freshness and quality of products. However, due to the complex structure and high cost of vacuum bottles, the use of vacuum bottle packaging is limited to a limited number of categories of products, and cannot be fully rolled out in the market to meet the needs of different grades of skin care product packaging.
While attaching importance to the protection and decoration of skin care product packaging, it began to focus on developing the functionality of skin care product packaging, so that the concept of "fresh", "natural" and "preservative-free" of the product is worthy of its name.
