What is a vacuum bottle? How to use it?
What is a vacuum bottle? The so-called vacuum bottle actually uses the principle of vacuum negative pressure, and pushes the piston at the bottom forward through atmospheric pressure, and uses this to push the contents upwards This design can block the entry of air and external bacteria to achieve a vacuum state Therefore, cosmetics can avoid contamination of their contents through this special container And how to use a vacuum bottle? Because a vacuum bottle does not have a straw like a regular container, it uses atmospheric pressure to push the contents out, so it usually takes 5 to 10 presses when used for the first time to expel the air in the bottle before the contents can be successfully squeezed out
Two disadvantages of vacuum bottles and how to deal with them
Disadvantage 1 of vacuum bottles: If there is air in the bottle, it needs to be pressed a few more times to expel the air
When using a vacuum bottle, sometimes you can’t squeeze out the contents This is because a small amount of air enters the bottle when the contents are filled At this time, just press a few more times, and the vacuum bottle will smoothly expel the air and push the contents out! In addition, when the contents belong to oil and wax, because its expansion coefficient is relatively large, it is easy to cause thermal expansion and contraction due to temperature changes, which reduces the volume of oil and wax, causing air to be generated in the bottle and the contents cannot be squeezed out At this time, just press a few more times to expel the air, or poke a small hole in the bottom of the bottle with a needle to promote the piston to move upwards!
