In our daily life, we all encounter the situation that the tin can cannot be opened. Why is this? What should I do if it can't be opened? Is there a way that does not damage the tin can and does not require a messy method? The editor will tell us about this problem today. Generally, there are three reasons why the tin can not be opened. One is that the screw is too tight, and the lid and the can are very tightly engaged, and the other is that the box has not been opened for a long time. However, the surface of the iron can is rusty, and the final situation is that there is a pressure difference between the pressure inside the iron and the outside, and the lid is adsorbed and cannot be opened. There is no way to open it. Now, the can manufacturer will tell us how to open the tin can.
If it is too tight and the pressure difference between the surface of the can, we can use a very simple method to open the bottle cap, turn the bottom of the can over and pat a few times, and then open it from the beginning. Then take a few more shots and take a little harder. Another way is to put the tin can in hot water, but it should be noted that only the lid part is placed in the water for a few minutes, using the principle of thermal expansion and contraction. , Can manufacturers are also able to open tin cans. If you encounter a situation where the iron can is rusty and cannot be unscrewed, try to remove the rust and put it in hot water. The effect is the same as the former. Humane.
