Cosmetic vacuum bottle refers to a container that can isolate the gas from the outside temperature or outside bacteria. Its contents can be completely isolated from the air, preventing the product from oxidative deterioration and breeding bacteria due to contact with the air, and improving the product grade with its high-tech concept. The popular thermos on the market consists of a cylindrical ellipsoid container with a piston at the bottom. The design principle of the cosmetic vacuum bottle is to use the contraction force of the spring to prevent the air from entering the bottle, resulting in a vacuum state, and at the same time use the atmospheric pressure to push the piston at the bottom of the bottle to move forward. However, since the spring force and atmospheric pressure cannot give enough force, the piston cannot be too tightly attached to the bottle wall, otherwise the piston will not be able to rise and move forward due to excessive resistance; on the contrary, if the piston is easy to move forward, it is easy to leak material, therefore, the thermos bottle The professional requirements for manufacturers are very high.

The launch of cosmetic vacuum bottles conforms to the newer development trend of skin care products and can effectively protect the fresh quality of products. However, due to the complex structure and high cost of cosmetic vacuum bottles, the use of vacuum bottle packaging is limited to a limited number of products, which 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 cosmetic packaging materials, vacuum bottle manufacturers have begun to focus on developing the functionality of skin care product packaging, so that the concepts of "fresh", "natural" and "preservative-free" of products are worthy of their names.

Vacuum bottle packaging technology is a new concept with absolute advantages. This packaging technology has helped many new brands and formulations go to market. Once a vacuum bottle package is assembled, from the filling of the package to use by the consumer, little air can enter the container and contaminate or decompose the contents. This is the advantage of vacuum bottle packaging - providing a safe packaging container for the product, avoiding contact with air and reducing possible changes and oxidation, especially for delicate natural ingredients that are in desperate need of protection. To avoid calls for added preservatives, vacuum bottle packaging is even more important for extending product shelf life.

Products packaged in vacuum bottles are different from ordinary standard suction or spray pumps. Vacuum-packed products use the principle of dividing the inner cavity to extrude the content. As the inner membrane sheet moves up into the bottle, pressure builds up and the contents are in a near 100% vacuum. Another vacuum method is to use a soft vacuum bag, placed inside a hard container. The concepts of both methods are almost the same. The former is widely used, which is a very important selling point for the brand, because it consumes less resources and can be recognized as "green".

Vacuum bottle packaging also provides precise dose control. With a set discharge port and a specific vacuum pressure, the dosage is precisely dosed every time, regardless of the matching head shape. Therefore, the dosage can be adjusted by changing a certain portion, from a few microliters to a few milliliters, according to the needs of the product. Product preservation and hygiene are the core values ​​of vacuum packaging.
