The contents of the vacuum bottle can be completely isolated from the air, avoiding the oxidative deterioration of the product due to exposure to air, breeding bacteria, and upgrading the product with its high-tech concept. The vacuum bottle that is used in the market consists of a cylindrical ellipsoidal container with a piston placed at the bottom. Its design principle is to use the contraction force of the spring, and not let the air enter the bottle, causing the vacuum state, and use the atmospheric pressure to push the piston of the bottom of the bottle to advance. However, due to the spring force and atmospheric pressure, sufficient force cannot be given, so the piston cannot be too tightly attached to the bottle wall, otherwise the piston will not be able to rise due to excessive resistance; on the contrary, if the piston is easy to advance and is prone to leakage, Therefore, vacuum bottles have very high requirements for the professionalism of the manufacturer.
The introduction of vacuum bottles conforms to the latest development trend of skin care products, which can effectively protect the fresh quality of products. However, due to the complicated structure of the vacuum bottle and the high cost, the use of the vacuum bottle packaging is limited to a limited number of products, and cannot be fully spread in the market to meet the needs of different grades of skin care packaging.
While paying attention to the protective and decorative nature of skin care products packaging, manufacturers began to focus on the development of the functionality of skin care packaging, so that the concept of "fresh", "natural" and "preservative-free" is worthy of the name.
