Despite the variety of food packaging and their constant evolution, the tin can remains one of the most reliable. Everything in it is good: the products are tightly packed and stored for a long time. One problem – it’s not that easy to open it.
Can knives
The easiest way to open canned food is with a can opener, or, as it is also called, a bottle opener or bottle opener. Can openers are different. A simple knife has two blades, straight and rounded. Using a straight line, the lid is pierced, and then, leaning on the rounded blade and moving clockwise, you need to cut the entire lid.
The hand can opener is a bit like scissors in construction. Its legs must be diluted, the wheel should be placed on the edge of the can and the legs must be squeezed to pierce the lid. Then, turning the key and moving clockwise, you need to cut the cover.
Automatic knives are very convenient. They operate on mains or batteries. All you need to do is to pierce the edge of the can with a knife and hold it by the bottom, and the knife, having made a circle around the can, will cut off the lid completely and without chipping.
Be extremely careful: sharp jagged edges can easily cut yourself. Do not bend the lid with your fingers, use a spoon or knife
If you need to open a tin can, but you don’t have an opener at hand, but you have a sharp knife, you can solve the problem with it. First you need to pierce the lid with a knife – put the tip on the edge of the lid and hit it from above. Further, many try to cut the lid along the edge, just as it is done with the opener, but this way you can ruin the knife and cut yourself severely. Therefore, it is better to cut the lid with a knife so that you get “petals” – you can bend them and get the contents of the jar. The easiest way to do this is cans with condensed milk.
But, suppose you do not have a knife at hand, and you find yourself in nature. To open the jar, you need a stone, concrete or stone surface, or some large metal structure. You need to press the jar against this surface and rub for a while. If you have a stone in your hands, just run it around the edges of the jar for a long time – the lid will fall out by itself. This is because the cans are sealed at the factory using conventional folding. Therefore, by erasing the folded edges, you can remove the cover.
Make sure that metal chips and dust do not get into the canned food, constantly blow them off the surface, and pry off the lid with a spoon or fork so as not to cut yourself
With spoons
Imported canned food is usually packed in cans made of metal much more plastic than domestic ones. Therefore, if you have a foreign-made jar, try opening it with a regular spoon. Just like a knife, place a spoon on the edge of the can and poke it through the lid, then use the spoon like a regular can opener.
However, domestic jars, for example with sprat, can also be opened with a spoon, or rather two or two spoons and a slipper. Do the following: attach one teaspoon to the edge of the head with a sharp end, and on top hit it with the edge of a sneaker or boot. The spoon will break through the lid. Now try to widen the hole in the jar a little so that the handle and the second spoon can go there. If you succeed, try to “break” the tin lid with a spoon, using the other as a lever.
