Benefits of airless bottles

A vacuum flask refers to a container that can isolate gas from the outside temperature or a container that isolates external bacteria.
Airless Bottle-Cosmetics
The contents of the airless bottle can be completely isolated from the air to prevent the product from being oxidized and deteriorated due to contact with the air, and the breeding of bacteria, and its high-tech concept is used to upgrade the product. The vacuum bottle in 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 to prevent air from entering the bottle, creating a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough power, the piston cannot be too tightly attached to the bottle wall, otherwise the piston will not be able to move forward due to excessive resistance; on the contrary, if the piston is to be moved forward easily and material leakage is likely to occur, Therefore, airless bottles have very high requirements for the professionalism of manufacturers.

The introduction of the airless bottle conforms to the latest development trend of skin care products and can effectively protect the freshness and quality of the products. However, due to the complex structure of the vacuum bottle and the high cost, the use of vacuum bottle packaging is limited to a limited number of categories of products and cannot be fully deployed in the market to meet the needs of different grades of skin care products.
While attaching importance to the protection and decoration of skin care product packaging, manufacturers began to focus on the functionality of skin care product packaging, making the concept of "fresh", "natural" and "preservative-free" worthy of the name.

Airless bottle-environmentally friendly fresh bottle
Environmentally friendly fresh bottle
The pressure head of the eco-friendly fresh bottle is different from that of the vacuum pump type bottle presser. The patented "environmentally-friendly fresh bottle" design concept is to simplify the complexity. The structure is mainly composed of the bottle body and the piston, which can hold skin care products of different viscosities. Liquid creams are all fine. The piston is directly propelled from the bottom of the bottle like a syringe, which prevents the product from contacting air during use, making the concept of "fresh", "natural" and "preservative-free" worthy of the name.
The environmentally friendly fresh bottle omits the spring pressure head in the vacuum system, so that the entire bottle holder is formed in one piece, which not only guarantees the vacuum inside the bottle holder, but also simplifies many parts. The cost is much lower than the vacuum bottle, and the PP material used is also easy to recycle , And achieve sustainable development in environmental protection. As the structure is relatively simple and the corresponding failure rate is relatively low, the quality of the bottle packaging device is guaranteed.
The syringe-type bottom advancement ensures the vacuum inside the bottle holder, so that the product does not come into contact with air and bacteria during the use period without the addition of the product, so as to avoid contact with the air to oxidize and deteriorate the product, and to maintain the freshness of the product for a long time; and It is convenient to quantify the taken-out cosmetics. Cosmetic manufacturers can safely and boldly manufacture pure natural skin care products without adding a lot of preservatives and antioxidants.
The skin care cosmetic packaging with the design concept of preservation can not only effectively protect the quality of cosmetics, but also meet the needs of luxurious and novel appearance products. Therefore, environmentally-friendly fresh bottles have naturally become a substitute for airless bottle packaging.
