An airless bottle is a container that isolates the gas from the outside temperature or a container that isolates the external bacteria. Its contents can be completely isolated from the air, avoiding oxidative deterioration and bacteria growth due to exposure to air, and upgrading its product quality with its high-tech concept. The airless bottle that is used in the market consists of a cylindrical ellipsoidal container plus a piston placed at the bottom. Its design principle is to use the contraction force of the spring, and does not allow air to enter the bottle, causing a airless state, and using atmospheric pressure to push the piston of the bottom of the bottle to advance. However, due to the spring force and atmospheric pressure, sufficient force cannot be given, so the piston cannot fit too tightly with the bottle wall, otherwise the piston will not be able to rise and advance due to excessive resistance; on the contrary, if the piston is easy to advance and is prone to leakage, Therefore, airless bottles have very high requirements for the professionalism of the manufacturer.
The introduction of airless bottles conforms to the latest development trend of skin care products, which can effectively protect the fresh quality of products. However, due to the complicated structure of the airless bottle and the high cost, the use of airless bottle packaging is limited to a limited number of products, and cannot be fully spread in the market to meet the needs of different grades of skin care packaging.
While paying attention to the protective and decorative properties of cosmetic packaging materials, manufacturers have begun to focus on the development of the functionality of skin care packaging, so that the concept of "fresh", "natural" and "preservative-free" is worthy of the name.
Airless packaging technology is a new concept with an absolute advantage. This packaging technology has helped many new brands and new formulations go on the market. Once the airless packaging is assembled, from the filling of the packaging to the consumer's use, almost minimal air can enter the container, contaminating or decomposing the contents. This is the advantage of airless packaging - it provides a safe packaging for the product, avoiding contact with air, reducing the possibility of changes and oxidation, especially the need to protect and delicate natural ingredients, avoiding the addition of preservatives In the call for sound, airless packaging is even more important for extending the shelf life of the product.
Airless-packed products are different from the standard suction pump type or spray pump. The airless packaging uses the principle of separating the inner cavity to squeeze out the contents. When the inner membrane moves up to the inside of the bottle, a pressure is created, at which point the contents are present in a airless close to 100%. Another way to airless is to use a airless pouch that is placed inside a rigid container and the concept of use is almost the same. The former is widely used and is an important selling point for brands because it consumes less resources and can be considered as“green”.
Airless packaging also provides precise dose control. When the discharge orifice and the specific airless pressure are set, the amount is accurate and quantitative regardless of the matching head shape. Therefore, the dosage can be adjusted by changing a part, from a few microliters or a few milliliters, depending on the needs of the product. Product preservation and hygiene are the key values of airless packaging. Once the contents are taken out, there is no way to replace the original airless packaging. Because the design principle is to ensure that every use is fresh, safe, and careless, the internal structure of our products, there is no doubt that the spring is rusty, and it will not pollute the contents.
Airless bottles are available in different styles. Each customer's preferences are different. Customers can choose the corresponding airless bottle style according to the consumption level of the brand positioning and the crowd. The price of airless bottles will be relatively high, and there will be different styles. The difference, customers can choose according to the brand positioning!
