Foaming Pump Head Manufacturers introduced that the contents of the vacuum bottle can be completely isolated from the air, to prevent the product from being oxidized and deteriorated due to contact with the air, and breed bacteria, and upgrade the product file with its high-tech concept. The vacuum bottle in the market is composed of a cylinder into an ellipsoid container and a piston at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, creating a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough power, the piston cannot be too tightly attached to the bottle wall, otherwise, the piston will not be able to move forward due to excessive resistance; on the contrary, if the piston is to be moved forward easily and material leakage is likely to occur, Therefore, airless bottles have very high requirements for the professionalism of manufacturers.
The introduction of the airless bottle conforms to the latest development trend of skincare products and can effectively protect the freshness and quality of the products. However, due to the complex structure of the vacuum bottle and the high cost, the use of vacuum bottle packaging is limited to a limited number of categories of products, which cannot be fully deployed on the market to meet the needs of different grades of skincare products. While paying attention to the protection and decoration of skincare product packaging, we began to focus on the development of skincare product packaging functionality, making the concept of "fresh", "natural" and "preservative-free" worthy of the name.
