In life, we often have such a phenomenon that the cup cannot be opened when drinking water, that is, the lid of the cup or bottle cannot be opened. Many people will be very troubled at this time. The following glass cup manufacturers will talk about the situation that the glass water cup cannot be opened, how to prevent and solve this problem?
Generally, the lid of the bottle cannot be opened because it has been left for a long time after pouring hot water. Sometimes I worry about water leakage, so the lid of the cup is screwed a little bit tight, and the result is that it cannot be opened. This phenomenon occurs because of the pressure. To prevent this situation, fill the glass cup with water close to room temperature; the lid of the water cup does not need to be tightened too tightly, as long as it does not leak.
Sometimes the lid still cannot be opened, what should I do?
1. Shake the water glass vigorously, and the lid can basically be unscrewed.
2. Put the cup in slightly higher temperature water, let it sit for a while, and then open it. Remember not to let the water temperature be too high to prevent the cup from bursting.
3. Stand the water glass upside down, tap the bottom of the water glass, and then unscrew the lid.
So when you encounter the situation that the lid of the glass or thermos cup cannot be opened, you can use the method mentioned above, which can help you solve the problem well, but pay attention to safety when opening it.
