Acrylic cream bottle2020-08-20下載文件：暫時沒有下載文件
?Now we often see the vacuum bottle is made up of an ellipsoid container and a piston, which is driven by the force of the spring. The contraction force is used to prevent air from entering the bottle, and then the atmospheric pressure is used to make the piston move forward. However, we must pay attention to the fact that the contraction force between the piston and the bottle wall is not too large, otherwise we are particularly difficult to push forward. Of course, if the special force can move forward, it will also affect the normal use of leakage, so the requirements of manufacturers are high.
It can be said that the introduction of vacuum bottles has brought us great convenience, especially for the female cosmetics industry. It can effectively ensure the quality of products and keep freshness. But because the structure of vacuum is more complex, so the price is relatively high. At present, we are not using vacuum bottles very much. With the progress of different grades of skin care products, we believe that more and more consumers will meet their needs. Through the above introduction, I believe you have a good understanding of the vacuum bottle. We all know the function of this kind of bottle. I believe that it will be more widely used in the future.
Cosmetic packaging bottle manufacturer
The contents of vacuum bottles made by Nami cosmetic packaging bottle manufacturers can be completely isolated from the air, so as to avoid oxidative deterioration and bacteria breeding of products due to contact with air, and improve the product profile with its high-tech concept. The common vacuum bottle on the market is composed of a cylinder into an ellipsoid container and a piston at the bottom. Its design principle is to use the contraction force of the spring and prevent air from entering the bottle, resulting in a vacuum state, and using atmospheric pressure to push the piston at the bottom of the bottle forward. However, the spring force and atmospheric pressure can not give enough force, so the piston can not fit the bottle wall too tightly, otherwise the piston will not be able to rise and advance due to the excessive resistance; on the contrary, if the piston is easy to move forward, it is easy to leak material, so the vacuum bottle has very high professional requirements for the manufacturer.
The purpose of the vacuum bottle is to isolate the substances in it from the air, which can ensure that the substances are oxidized and produce bacteria, which will affect our normal use. It can be said that its high-tech concept can improve the quality of products, of course, the requirements for producers will be greatly improved, and professional production is needed.
Because the vacuum saves a lot of parts, which saves a lot of resources. It is also very good in environmental protection. Because the requirements of structure are relatively high, which also requires high requirements for manufacturers. I believe that the probability of problems in the process of use will be very low. The use of vacuum bottle packaging cosmetics can not only ensure the quality of cosmetics, but also make cosmetics look generous.
