A vacuum bottle refers to a container that can isolate the gas from the outside temperature or a container that isolates external bacteria.

The contents of the vacuum bottle can be completely isolated from the air, preventing the product from oxidative deterioration and breeding bacteria due to contact with the air, and enhances the product quality with its high-tech concept. The vacuum bottle commonly used in the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom. Its design principle is to use the contraction force of the spring to prevent the air from entering the bottle, resulting in a vacuum state, and to use the atmospheric pressure to push the piston at the bottom of the bottle forward. However, since the spring force and atmospheric pressure cannot give enough force, the piston cannot be attached too tightly to the bottle wall, otherwise the piston will not be able to rise and move forward due to excessive resistance; Therefore , the vacuum bottle has very high requirements for the professionalism of the manufacturer.

Many people are using vacuum bottle packaging, or because of curiosity or because there are fewer products to be pressed, if they want to unscrew the press pump to see, they will see that there is no straw on the press pump, thinking that the straw is broken. In fact, this is for the vacuum bottle. wrong operation.

When pressing the vacuum bottle , the bottom vacuum stopper is pushed up by the principle of pressure, and it can be pressed out smoothly after several more pressings to discharge the air.

If you are impatient, you can press the bottle upside down and down, so that it will not cause product backflow, and it can only go out but not in, and fundamentally prevent pollution and oxidation.

Therefore, the vast majority of skin care products that can assist in the treatment of sensitive skin, acne skin and other problematic skin are basically packaged in vacuum bottles , which fundamentally eliminates product contamination, thus ensuring the activity and safety of the product.
