How to restore the vacuum bottle when it is used up
1. Remove the pump head. First of all, we need to remove the pump head, because after the vacuum bottle is used up, its piston will push to the upper part, so that the product inside can be squeezed out. The only way to get the piston down is to open the pump head first.

2. Clean the bottle. Clean the bottle after disassembly, and then put in new cosmetics after it is convenient. Rinse the inside of the bottle and the pump head repeatedly with clean water, then pour out the water and put it in a ventilated place to air dry.

3. Press the plunger. Find the piston after drying. If the vacuum bottle is relatively small, you can press it down with your fingers. If the vacuum bottle has a large capacity, you should use a wooden stick or other hard objects to press the piston to the bottom. For the spring device, appropriate force may be required during the pressing process, and the piston needs to be temporarily fixed after pressing.

4. Install the pump head. After the piston reaches the bottom, put in new cosmetics or other products. Do not load too slowly, otherwise it will easily overflow, and then restore the pump head. It should be noted that the pump head of some vacuum bottles cannot be reinstalled after disassembly, but Some vacuum bottles can be restored, and the pump head can be turned back carefully to continue to use.

Are vacuum bottles disposable?
From a design point of view, the vacuum bottle is not disposable, but because of its special structure, it is usually difficult to restore it after one use. It is made of vacuum to prevent the products inside from contacting external bacteria. The vacuum effect has been lost in the restoration, so many people do not choose to restore it, but in fact, it can be reused if you master the restoration technique.
