What is a vacuum bottle? How to use it?
What is a vacuum bottle? A so-called vacuum bottle actually utilizes the principle of vacuum negative pressure, using atmospheric pressure to push the piston at the bottom forward, and thereby pushing the contents upwards This design can block the entry of air and external bacteria to achieve a vacuum state Therefore, cosmetic products can avoid contamination through this special container And how to use a vacuum bottle? Since vacuum bottles do not have a straw like ordinary containers, they use atmospheric pressure to push the contents out Therefore, when used for the first time, it usually requires 5 to 10 presses to expel the air inside the bottle before the contents can be successfully squeezed out
Two disadvantages of vacuum bottles and how to deal with them

When using a vacuum bottle, sometimes the contents cannot be squeezed out This is because a small amount of air enters the bottle during filling At this time, just press a few more times, and the vacuum bottle will successfully expel the air and push out the contents! In addition, when the contents are oily or waxy, due to their larger expansion coefficient, they are prone to thermal expansion and contraction due to temperature changes, causing the volume of the oil and wax to shrink, creating air in the bottle and making it difficult to squeeze out the contents At this time, just press a few more times to expel the air, or use a thin needle to poke a small hole at the bottom of the bottle to promote the piston upward!
