2017-07-17 12:27:55

The contents of the vacuum bottle and the air can be completely isolated, to avoid the product due to contact with the air oxidation and deterioration, breeding bacteria, and its high-tech concept to enhance product stalls. The vacuum bottles on the market are made up of a cylindrical oval container plus a piston at the bottom of the placement.

Its design principle is to use the spring of the contractile force, and not let the air into the bottle, causing a vacuum state, and the use of atmospheric pressure to promote the bottom of the piston forward. But because the spring force and atmospheric pressure can not give enough strength, so the piston can not fit too tight with the bottle wall, otherwise the piston will be too large to rise and can not rise; the other hand, to make the piston easy to advance and prone to leakage material situation, So the vacuum bottle on the manufacturer's professional requirements are very high.
The launch of the vacuum bottle conforms to the latest development trend of skin care products, can effectively protect the product fresh quality. However, due to the complexity of the vacuum bottle structure, high cost, the use of vacuum bottle packaging is limited to a limited number of categories of products, can not be fully rolled out in the market to meet the needs of different grades of skin care packaging.
Manufacturers in the emphasis on skin care skin care packaging protection and decoration at the same time, began to focus on the development of skin care packaging functional, so that the product "fresh", "natural", "preservative-free" concept worthy of the name.
