How To Use Vacuum Bottles For Dispensing Cosmetics

When using the vacuum bottle, press and hold the top, and the piston on the bottom will run upward to squeeze out the contents. When the contents of the bottle are used up, the piston will move to the top. When the piston reaches the bottom, the vacuum bottle can be removed. The pump head and other parts can be used repeatedly by disassembling and reinstalling them.

The vacuum bottle uses the contraction force of the spring to prevent outside air from entering the vacuum bottle. Use atmospheric pressure to push the piston at the bottom of the bottle forward. The contents of the vacuum bottle can be completely isolated from the air, preventing the product from oxidizing, deteriorating, and breeding bacteria due to exposure to air, and using its high-tech concept to enhance product quality.

The popular vacuum bottles on the market are composed of a cylinder-shaped 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 and create a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, the spring force and atmospheric pressure cannot provide sufficient force.

Therefore, the piston cannot be too tightly attached to the bottle wall, otherwise the piston will be unable to rise and move forward due to excessive resistance; on the contrary, if the piston is to move forward easily, material leakage will occur, so vacuum bottles require very high professionalism from the manufacturer.
