What should I do if the mug lid of the vacuum mug cannot be opened?
In daily life, do you often encounter such problems? When you put a mug of hot water for a period of time, even if you use the strength of breastfeeding, you still can’t open the lid.
This kind of situation often happens in life, so why is this? When we encounter this situation, how should we solve it? Let the water mug network tell you!
When you pour hot water into the mug, the air and water in the mug are soaring. After being placed for a while, they all become cold and shrink, causing a large pressure difference between the inside and outside of the mug. Under this pressure, it is very difficult for us to unscrew the lid.
Since the pressure difference caused by this temperature difference makes us unable to open the lid, it is necessary to overcome this pressure difference in order to unscrew the lid. The specific measures are as follows:
1. Turn the mug upside down, slam the bottom of the mug a few times, and then screw the lid. .
2. Use a strong screw. When the force we use is large enough (that is, when the friction between the force we generate and the lid is greater than the pressure created by the temperature difference), the lid is unscrewed.
3. Use the key (other flaky metal is also OK, insert it wider, do not hurt the lid). Gently lick it in the gap between the lid and the mug, and the air will go in. It is easy to screw it. opened.
4, can not open is generally a negative pressure inside the mug, you can put the mug in the hot water bubble, wait for the water in the mug to heat up, when the volume expands, it is easy to open.
5, first put into the refrigerator to freeze, take it out and use hot water on the lid (just cover), to ensure that you can open.
6. Heat the lid quickly to create a gap between it and the mug.
7, can not open is generally a negative pressure inside the mug, you can put the mug in the hot water bubble, wait for the water in the mug to heat up, when the volume expands, it is easy to open. .coffee mug manufacturer
