Nowadays the airless cosmetic containers
we often see is composed of an ellipse container and a piston, which is driven by the force of the spring. It uses the force of contraction to prevent air from entering the bottle, and then use atmospheric pressure to push the piston forward. However, we must pay attention to the fact that the contraction force between the piston and the bottle wall is not too large, which will make the push become not easy. Of course, if only special efforts can be made to go forward, which will also affect the normal use, taking place the leakage situation.
The introduction of airless cosmetic containers has brought us great convenience, especially for women's cosmetics industry. It can effectively guarantee the quality and freshness of products. But the price is relatively high for the sake of the complex structure of vacuum.
The contents of airless cosmetic containers of our factory can be completely separated from air, so as to avoid oxidation deterioration and bacterial growth of products due to their exposure to air.
Because vacuum saves a lot of parts, which saves a lot of resources so as to do a good job in the environmental protection. The requirement of the container structure is relatively high, which also puts forward higher requirements for manufacturers. Using airless cosmetic containers to pack cosmetics can not only ensure the quality of cosmetics, but also make cosmetics look generous.
