The contents of the vacuum flask can be completely isolated from the air to prevent oxidative deterioration of the product due to exposure to air, to breed bacteria and to enhance the product profile with its high-tech concept. A commercially available vacuum bottle consists of a cylindrical, ellipsoidal container plus a piston mounted to the bottom. Its design principle is the contraction force of the spring, and does not allow air into the bottle, resulting in a vacuum state, and the use of atmospheric pressure to promote the bottle bottom piston forward. However, due to the spring force and atmospheric pressure can not give enough force, so the piston can not be too tight fit with the bottle wall, or the piston will not be able to rise due to excessive drag forward; the other hand, if you want to make the piston easy to advance and prone to leakage, Therefore, the vacuum flask on the manufacturer's professional requirements are very high.
The introduction of vacuum bottles conforms to the latest development trend of skin care products, which can effectively protect the fresh quality of the products. However, due to the complicated structure and high cost of the vacuum bottle, the use of the vacuum bottle packaging is limited to a limited number of categories and can not be fully rolled out in the market to meet the needs of different grades of skin care products.
While valuing the protection and decoration of skin care and skin care products, manufacturers have begun to focus on developing the functionality of skin care products packaging so as to make the concept of "fresh", "natural" and "preservative free" worthy of the name.
