Lipstick Tube Lip balm is a personal care product that is usually applied to the lips. After applying the lip balm on the lips, it can effectively prevent the lips from cracking and peeling due to the dry weather. The main ingredients of lip balm include beeswax, petroleum jelly, menthol and camphor. In addition, in order to enhance the moisturizing function of the current lip balm, vitamins, salicylic acid and other ingredients are added. The introduction of the airless bottle conforms to the latest development trend of cosmetics and can effectively protect the quality of the contents of the website. However, due to the complicated structure of the Airless  bottle and the high production cost, the use of the Airless  bottle is limited to individual high-priced and demanding types of products, which is difficult to fully spread on the market to meet the needs of cosmetics of different grades.

1.Airless bottle design principle (basic rule): The design principle of the Airless bottle is based on atmospheric pressure, and it is very dependent on the pump output of the pump set. The pump set must have excellent one-way sealing performance and block air (AIR) from returning to the bottle. Cause low pressure in the bottle. When the difference between the low-pressure area in the bottle and the atmospheric pressure is greater than the friction between the piston and the inner wall of the bottle, the atmospheric pressure will push the large piston in the bottle to move. Therefore, the large piston cannot be attached too tightly to the inner wall of the bottle, otherwise the large piston will not be able to advance due to excessive friction; on the other hand, if the large piston and the inner wall of the bottle are too loosely attached, leakage will occur, so the Airless  bottle is important for the production process The professional requirements are very high.

2.Airless bottle product characteristics: The Airless bottle also provides precise (precise) dosage control. When the diameter, stroke and elasticity of the pump set are set, regardless of the shape of the matching button, each dosage is accurate and quantitative . Moreover, the displacement of the pressing can be adjusted by changing the parts of the pump set, with an accuracy of 0.05 ml, depending on the needs of the product.

Once the Airless  pump bottle is filled, almost no air or water can enter the container from the production plant to the end of the consumer's use, which effectively prevents the contents from being infected during use and prolongs the effective use of the product.
