Is the inner tank of a pressure thermos bottle easy to explode?

It is not easy to explode, and the performance of the air pressure thermos is still very good

There are usually two reasons for the explosion:

First, uneven heating, cold Thermal temperature difference is too large. For example, the weather is hot and the air pressure is high; or in the colder winter, the temperature of the bottle is too low, and the bladder of the boiled water bottle is partially heated after contact with hot water, causing a sudden explosion.

The second is that the air expands and the pressure is too high. This is why most thermoses explode. When the bottle is filled with hot water, if the stopper is too tight, it will cause the pressure inside the bottle to explode. Therefore, sometimes the boiling water bubbles we carry filled with water will burst suddenly on the road.
