Do you know the disassembly steps of cosmetic airless bottle? Let's talk about the disassembly steps of the cosmetic airless bottle together.
Cover it with warm water and a hot towel, even if it is cold and the negative pressure absorbs it, the volume of the gas inside becomes smaller. After covering it with heat, the volume of the gas inside becomes larger, the negative pressure will be smaller, and it is easy to unscrew. Vacuum bottles are different from ordinary containers that use long tubes to absorb skin care products, or simply use a lid to cover. The vacuum bottle uses the vacuum short tube and the bottom piston to remove the air in the bottle, and the internal vacuum is made by pressing. This technology can prevent the contents from coming into contact with the air, remove doubts about product oxidation and deterioration, and achieve the benefits of anti-oxidation, anti-pollution, and no residue. Do not open the bottle body during the use of the vacuum bottle. If it is accidentally opened, cover it back as soon as possible, so as not to affect the use of the vacuum pump due to the pressure difference between the inside and outside of the bottle.
How to restore the vacuum bottle when it is used up
You can first disassemble the pump head, etc., and then poke the tray down with a hard object a little longer than the bottle, and the vacuum bottle will be restored. After the pump head of the vacuum bottle is restored, the vacuum bottle can be filled with cosmetics again for repeated use. But wash the bottle before filling. Generally speaking, when the vacuum bottle is pressed, the bottom tray will run up to squeeze out the contents. When the contents are used up, the tray has already run to the top. Reuse is to press down the tray that ran to the top again, and that's it. In cosmetics, the vacuum bottle is very beneficial, which can completely isolate the cosmetics in the vacuum bottle from external bacteria. The contents of the vacuum bottle can be completely isolated from the air, so as to prevent the product from oxidative deterioration and bacteria breeding due to contact with the air. The vacuum bottle commonly used in the market is composed of a cylindrical or ellipsoidal 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. The vacuum bottle is the best bottle to solve the oxidation/qualitative change of the skin care product paste due to contact with air/bacteria. The vacuum bottle uses the vacuum short tube and the bottom piston to remove the air in the bottle, and the internal vacuum is made by pressing. This technology can prevent the contents from coming into contact with the air, remove doubts about product oxidation and deterioration, and achieve the benefits of anti-oxidation, anti-pollution, and no residue.
