Basic knowledge of airless bottles

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 placed at the bottom. 

Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, resulting in 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 force, 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 move forward easily and it is prone to material leakage, Therefore, airless bottles have very high requirements for the professionalism of manufacturers.

Vacuum packaging technology is a new concept with absolute advantages. This packaging technology has helped many new brands and new formulas go on the market smoothly. Once the vacuum packaging is assembled, from filling the packaging to the consumer's use process, almost minimal air can enter the container, contaminate or decompose the contents. This is the advantage of vacuum packaging. It provides a safe packaging empty for the product to avoid contact with air and reduce the possibility of changes and oxidation. Especially for the delicate natural ingredients that need to be protected, it is necessary to avoid adding preservatives. Among the calls, vacuum packaging is more important to extend the shelf life of products.

Vacuum-packed products are different from standard pumps or spray pumps with common straws. Vacuum packaging uses the principle of separating the inner cavity to squeeze out the contents. When the inner diaphragm moves up to the inside of the bottle, a pressure is formed, and the contents are present in a vacuum state close to 100% at this time. Another way to vacuum is to use a vacuum soft bag, which is placed inside a rigid container. The concept of use of the two is almost the same. The former is widely used and is a very important selling point for brands, because it consumes less resources and can also be regarded as "green".

Vacuum packaging also provides precise dosage control. When the discharge hole and specific vacuum pressure are set, regardless of the matching head shape, each dosage is accurate and quantitative. Therefore, the dosage can be adjusted by changing a certain part, from a few microliters or a few milliliters, all according to the needs of the product.

Product preservation and hygiene are the key values of vacuum packaging. Once the contents are taken out, there is no way to put them back into the original vacuum packaging. Because the design principle is to ensure that every use is fresh, safe, and worry-free, the internal mechanism of our products does not have the doubt of spring rust, and will not contaminate the contents.

Consumers' cognition also affirms the value of vacuum products invisibly. Compared with general standard pumps, sprays, straws, and other packaging components, vacuum packaging is smoothly used, with a fixed dosage and high-end appearance, making it occupy a large market for luxury products.
