Learn about vacuum bottles in one minute

The introduction of vacuum bottles conforms to the development trend of skin care products and can effectively protect the freshness and quality of products. However, due to the complex structure and high cost of vacuum bottles, the number of products used in vacuum bottle packaging is limited and cannot be fully rolled out in the market to meet the needs of different levels of skin care. Product packaging. While focusing on the protection and decoration of skin care product packaging, manufacturers have also begun to focus on developing the functionality of skin care product packaging, so that the concepts of "fresh", "natural" and "preservative-free" of the products are worthy of their names.

Vacuum packaging technology

Vacuum packaging technology is a new concept with advantages. Helped many new brands and formulations enter the market. Once the vacuum package is assembled and the consumer uses the self-filling package, little or no air can enter the container and contaminate or break down the contents. This is the advantage of vacuum bottles. It provides a safe empty container for the product, avoiding contact with air, reducing the possibility of change and oxidation, especially for delicate natural ingredients that need to be protected. Avoid added preservatives. Among the demands, vacuum bottles are more important to extend the shelf life of products.

Unlike ordinary standard pumps or straw spray pumps. The vacuum bottle uses the principle of dividing the inner cavity to squeeze out the contents. As the inner diaphragm moves up into the bottle, the pressure increases and the contents are brought to a near-vacuum state. Another method of vacuuming is to use a soft vacuum bag and place it in a rigid container. These two concepts are similar. The heavy use of the former is an important selling point for the brand, as it consumes fewer resources and can also be recognized as "green".

The vacuum bottle also provides precise dosage control. When the discharge port and specific vacuum pressure are set, no matter what shape the matching pressure head is, each dose is accurately measured. So depending on the needs of the product, the dosage can be adjusted by changing a certain part, from a few microliters to a few milliliters.

Product preservation and hygiene are the core values of vacuum packaging. Once the contents have been removed, they cannot be returned to the original vacuum packaging. Since the design principle is to ensure that every use is fresh, safe, and worry-free, there is no doubt about the internal mechanism of the product, and the springs will rust or contaminate the contents.

Commonly used vacuum bottles on the market consist of a cylindrical oval container and a piston at the bottom. The design principle is to use the contraction force of the metal spring to prevent air from entering the bottle to create a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, since the spring force and atmospheric pressure cannot give enough force, the piston cannot be too close to the bottle wall, otherwise the piston will be unable to rise and move forward due to too much resistance; therefore, the failure rate of vacuum bottles is very high. Moreover, the piston system leaves too little space for design, which is not conducive to shaping the brand's unique image through appearance and decoration.
