Vacuum bottle is a container that can isolate the gas from the outside temperature or isolate the external bacteria. Its contents can be completely isolated from the air to avoid oxidation and deterioration of the product due to exposure to air and the growth of bacteria, and to enhance the product grade with its high-tech concept. The common vacuum bottle on the market consists of a cylindrical oval container with a piston placed at the bottom.

Its design principle is to use the contraction force of the spring and not to let the air into the bottle, resulting in a vacuum state, while using atmospheric pressure to push the piston at the bottom of the bottle forward. But because the spring force and atmospheric pressure can not give enough force, so the piston can not fit too tightly with the wall of the bottle, otherwise the piston will be too much resistance and can not rise forward; on the other hand, if the piston is easy to advance and easy to leak material, so the vacuum bottle is very high requirements for the professionalism of the manufacturer.

The introduction of the vacuum bottle responds to the latest 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 the vacuum bottle, the use of vacuum bottle packaging is limited to a few categories of products and cannot be fully spread in the market to meet the needs of different grades of skin care packaging.


Manufacturers are focusing on developing the functionality of skincare packaging while emphasizing the protective and decorative aspects of cosmetic packaging, so that the concepts of "fresh", "natural" and "preservative-free" products are true to their names.


Vacuum packaging technology is a new concept that has definite advantages. This packaging technology has helped many new brands and formulas to launch successfully. Once vacuum packaging is assembled, from the time the package is filled to the time it is used by the consumer, very little air can enter the container and contaminate or break down the contents.

This is the advantage of vacuum packaging - it provides a safe container for the product, avoiding contact with air and reducing the likelihood of changes and oxidation, especially in the case of delicate natural ingredients that need to be protected, which is all the more important to extend the shelf life of products amidst the call to avoid adding preservatives.


Unlike standard pumps or spray pumps that are commonly used with straws, vacuum packaging uses the principle of separating the inner cavity to squeeze out the contents. When the inner diaphragm moves up to the interior of the bottle, a pressure is formed and the contents exist in a vacuum of nearly 100%. The other vacuum method is the use of a soft vacuum bag placed inside a rigid container. The former of being widely used is an important selling point for brands, as it consumes less resources and can be recognized as "green".
