Application of vacuum pump

Vacuum pumps are increasingly used in cosmetic products, especially in the field of skin care products. Although consumers do not necessarily know what a vacuum pump is, for them, they can feel the various conveniences in the process of using the product. With its unique design features, vacuum pumps have the following advantages:

The contents are not in contact with air. This is one of the biggest advantages of vacuum pump products. Since the content of the product does not come into contact with the air, oxidation of the product can be avoided, and on the other hand, less preservatives are added to the product.

Because the bottle body of the vacuum pump uses a scraper-type piston design, the residual rate of the product is relatively low, generally below 5%. For more expensive products, such as serum and eye cream, it can undoubtedly reduce waste. Especially when choosing a transparent bottle body, the bottle wall of the vacuum bottle is always kept relatively clean during use, while when choosing a general lotion pump with a straw, the product does not look very beautiful because the product remains on the bottle wall.

It can be used without any limitation of angle. The vacuum pump can be used 360 degrees. This feature can be used in many applications. For example, in the American market, it has been used as a collar net product.

However, due to the design limitations of the piston technology, the vacuum pump also restricts the design limitations of the shape of the bottle body, which are generally circular or elliptical. More and more products have begun to use double-layer bottle design to overcome this limitation.

There is no big difference between the vacuum pump and the general lotion pump in the pump body, that is to say, the general lotion pump can theoretically be converted into a vacuum bottle. The difficulty of the vacuum pump lies in the sealing performance of the various parts. Since the air tightness is required to be extremely high, the requirements for the mold and parts are relatively high. Otherwise, it is easy to cause the material body to not be pumped out.
