If you are not careful, you will cut your hand. Mastering skills is very important. How to open a can?

Many foods and drinks that we come into contact with every day are packed in cans. Like the cola we usually drink, canned fish with tomato sauce, canned fruit, eight-treasure porridge and so on, they are all packaged in this way. Moreover, in the emerging take-away industry, some merchants also use canned food for packaging, so that no one will touch the food during transportation, which is hygienic and not easy to spill. This kind of packaging will make customers feel very at ease about the hygienic condition of food. But this kind of packaging also has a big disadvantage, that is, you will accidentally scratch your hand when you open it. Just like the cola we usually drink, this can is relatively easy to open. One is that you need to remove the tab along the fingerprint. Generally, you need to pull skillfully, otherwise it is easy to break the pull ring. There is also a lower push-pull ring, which is relatively simple. Just pull the pull ring up, and the lower part of the pull ring will push the marked part of the bottle mouth down, and the bottle mouth will open naturally. If you drink coke through a straw, just turn the pull ring to the opening and insert the straw into the pull ring. When opening a can of eight-treasure porridge, you need to hold the bottle of eight-treasure porridge with one hand, put the index finger of the other hand into the pull ring, press the position below the pull ring with your thumb, and then pull the index finger appropriately. After slowly pulling out an opening, start to adjust the direction of force, and slowly pull back along the force. Of course, you must be careful not to touch the edge of the lid with your fingers. Most cans are made of aluminum or tinplate, so they are very sharp and easy to cut your fingers. Be sure to pay attention Then open the canned fish with tomato sauce, because the canned fish with tomato sauce belongs to flat round packaging, and the lid area is relatively large when opening, so it is difficult to open. Generally speaking, other tools are needed to open cans. After opening the opening with the pull ring, slowly open the can along the edge with a kitchen knife or scissors, and pull down the lid with the help of tools. If you pull it hard, it will break the pull ring and make it impossible to open, so it takes methods and skills to open different cans.
