How to open a canned jar. How to open a tin can without an opener: description of methods. How to open canned food with a flat stone

It is common for every person to face difficulties. Sometimes obstacles arise that can only be overcome if you have some available means of assistance. But what to do if you don’t have the necessary helpers?

For example, there are cases when a person is far from civilization and because of this finds himself in a hopeless situation. How to open a tin can in this case? There are several proven methods. It is necessary to know about each one so as not to be left without food later. It is worth considering these methods in as much detail as possible.

First way

Perhaps the simplest method that humanity could come up with is the use of a special opener. Probably everyone knows how to open a jar with its help.

This method does not require much effort. All you need is the target itself and a regular bottle opener. The tin can must be placed on a hard, level surface. Insert the opener into the top and use a circular motion to open the can.

Second way

If you don't have an opener or it's simply broken, don't despair. This method will tell you how to open a jar. All you need is a regular table knife. It will be better if its blade is not long, but it itself is wide and has a comfortable handle.

Many people make the mistake of trying to use a table knife as a can opener. If you try to open the jar using the previous method, you will only break the knife and waste your energy.

And yet, how to open the lid of a jar with an ordinary knife? Place the object of influence on a flat surface and, with a sharp movement of your hand, insert the tip of the knife blade into the middle of the lid. Next, making forward movements with your hand, cut a line to its side. After this, put the knife in its original position and draw a line in the opposite direction. The next step is to make a cut perpendicular to the existing one. To do this, also place the blade in the middle and make slits in one direction and then in the other direction.

As a result, you will get a kind of cross made of cuts. All you need to do is peel back the petals and the jar is open!

Third way

If you are far from civilization and don’t even have an ordinary knife at hand, a stone will come to your aid. Travelers and people whose profession involves long-distance business trips probably know how to open a jar in this way.

Take the jar and place the bottom on your palm. Holding it tightly with your hands, begin to move along the base of the stone, as if erasing the lid. Within a few minutes you will notice that the aluminum surface has begun to wear off. The main thing in this case is to prevent the contents from falling out of the container.

Fourth method

If you don’t even have an ordinary stone on hand, don’t despair, you won’t have to go hungry. Similar to the previous method, this method involves partial erasing of the aluminum surface, only you will have to use ordinary asphalt or concrete rather than stone.

Place the target directly on the asphalt and step on it with your foot. With little effort, begin to rotate your foot as if you were dancing a twist. Within a few minutes the lid will begin to wear off. In this case, the main thing is also not to overdo it, otherwise the entire contents of the jar will end up on the ground.

Fifth method

There is another very popular method for opening canned food. To use it you will need fire. This can be either a regular fire or a simple lighter or matches.

Heat the jar on one side. Surely, everyone remembers from their school days that bodies tend to expand under the influence of heat. This is elementary physics. Due to the fire, the aluminum walls will begin to expand and pull the bottom and lid along with them. This way the jar will simply crack, and all you have to do is carefully unpack it.

However, when using this method, you must protect your hands. You can wrap them in a towel or wear thick gloves. Make sure that the fire does not spread to the fabric and start a fire. For greater safety, it is better to place the can in the fire or hold it with the help of some devices at a considerable distance from the hands.

To summarize, we can say that there are a lot of different ways to open a can of canned food. Which one is best for you depends on the initial situation, the size of the jar, its contents and the availability of available equipment.

Recently, manufacturers often produce canned food with existing opening rings. You just need to pull it and the lid will open smoothly. Give preference to this type of canned food, and you will not find yourself in an awkward situation when you need to solve the question: “How to open aluminum can with your own hands?"

Our magazine continues to sprinkle camp romance from bright monitors. And why? But because it’s summer, mosquitoes, a fire, “The bend of a yellow guitar” in drunken voices and the romance of summer nights. What do you want most of all in the oxygen-enriched fresh air? That's right, have a snack. Well, or just eat. And the most popular food is, as you know, stew. But bad luck, it’s impossible to take everything into account, and you will definitely forget the knife. Or a bottle opener. And since hunger is putting more and more pressure on the morale of the team, something needs to be decided. You can just throw the can as hard as you can against the stones, but not everyone likes sandy meat. And licking pieces from the mortal earth is not very pleasant. Fortunately, human ingenuity has come up with other ways.
In general, these methods will be useful not only on a hike, but in any place where hunger overtakes you.

Friction

If you are not bothered by aluminum shavings in your food and leaked liquid, we recommend using this method, as old as the Earth itself.
1. Find a large rock or just any other very hard surface (concrete bunker).
2. U modern cans(and we hope that you eat modern canned food), sealed using a seaming machine, there is a protrusion on top, which is the place connecting the lid and the jar itself. You take it and start rubbing this protrusion on the stone
4. As soon as you see liquid starting to flow out of the jar, stop and turn the jar over.
5. Pry the tattered jar with something - the lid will fall off without difficulty.
6. Enjoy!

Spoon

And again the great force of friction saves you from hunger!
If you don’t have a bottle opener, you can use a simple spoon. It's always there, unless you eat with your hands, of course. The main thing is that the spoon is not aluminum, otherwise it is unknown who will emerge victorious from the duel - the jar or the spoon.
1. Take a simple tablespoon.
2. Using the side of a spoon, rub the lid of the jar at the side. You won't have to rub it for long. You yourself will feel the moment when you need to stop.
3. Press the edge of the spoon onto the places you just rubbed.
4. The jar will be pressed, and you can take out the food.

With bare hands

The next method is for real men with big hands without traces of a pedicure and a great desire to show off in front of others. The main thing is to have considerable strength in your hands and practical experience. By the way, if you haven’t forgotten, cans can be elongated and flat. With the right technique, you can open both.
1. Take a jar. You squeeze it at both ends with your palms.
2. Place your big powerful fingers in the middle of the can, squeeze it with your palms and press a dent with your fingers.
3. Bend the can in the other direction.
4. You bend it until the flimsy aluminum breaks.
By the way, it is better to take an aluminum can. She is, so to speak, more pliable. But this is not the only nuance. As you understand, the raging juices will frantically burst out of the tin, staining everything around. So it’s a good idea to put it in a bag.

Saw

The option is terribly simple and banal. If you have nothing to open it with, but you have a saw lying around, use it.
1. Take a hacksaw.
2. Cut off the top of the can.
3. That's it. Did you think it would be something fantastic?

Hammer and knife/chisel/screwdriver

This method is very, very risky. The fact is that both the hammer and the chisel can bounce off and injure something like that. But we believe in you. In addition, on a hike, in the absence of an ax and a chisel (well, who carries a chisel with them on a hike!), you can use a knife and a stone. But here the stakes are higher. A hammer and chisel (or a flat-head screwdriver) is more of a garage option when you decide to have a snack in your workshop, but, as always, you don’t have a bottle opener at hand.
1. Take a hammer and chisel.
2. Place the chisel on the top edge of the jar.
3. Gently tap the tool to make the first hole. Keep the chisel straight, not at an angle, otherwise there is a risk that it will slip.
4. Rotate the can a little, then position the chisel for the new hole. Strike again. Continue hitting the top of the jar until the lid is completely open.

Live and learn. This statement is true for absolutely all areas of our lives. You can live a certain number of years, but still not learn how to open, for example, portioned cream.

This post contains 10 products that can be opened quickly and conveniently, but we didn’t know about it. Well now we know.

Sugar packet

This type of sugar packaging was invented by Benjamin Eisenstadt. The idea is simple: break the bag in half, and do not tear off a corner. Thus, all the sugar ends up in the cup, and the person has one neat candy wrapper in his hand.

Pringles chips

It’s much easier to eat them if you put a folded piece of paper in the jar.

Plain chips

You will need to pierce the packaging with scissors or another sharp object.

Tic tac

It is enough to turn the jar over, and the dragee itself will fall into a special hole in the lid. Yes, we didn't know either.

Portioned cream

You need to pull the “tab” (in the photo on the right it is at the bottom of the container) and move it across the jar. The cream easily pours into the cup and mixes with the coffee.

Coffee at McDonald's

This is the story with coffee: there is no need to suffer and completely tear off the lid. There is a special plug on it that closes the drinking hole in the lid - you just need to bend it all the way, and it will remain fixed in the recess.

Pour juice from the package

The neck of a juice pack is usually located closer to one edge. If you pour juice so that it is at the bottom, air does not enter the bag, the juice gurgles and splashes. The correct way to pour is the same as pouring gasoline from a canister - hold the juice pack so that the neck is higher. Then the juice will flow smoothly and without splashing.

Coconut

Carefully inspect the coconut and find 3 black dots located nearby. Pierce one of the points with a screwdriver or a sharp thin knife, insert a straw and drink. To open a coconut, you need to mentally draw a circle, which should be located a little closer to those same black eyes from the middle. Tap the entire fruit along an imaginary line and it will split open.

Canned food

How to open a tin can with an opener. We hold and move the opener towards us and at the same time turn the can. We will get a clear, perfect cut without distortion.

Champagne

Canned food has long been firmly established in our lives. They are used not only by those who are too lazy to cook on their own and prefer to only heat up semi-finished products from an iron can, but also by professional chefs who often add canned vegetables, green peas and other products to their original dishes. At the same time, some novice cooks may have problems opening a tin can. This question becomes especially relevant when you have to cook in unusual conditions and you don’t have the necessary tools at hand. What to do in such cases?

However, we’ll move on to extreme situations a little later; we’ll start this conversation with standard methods of opening cans.

Usually, special devices are used for this - can openers. The simplest design of products of this kind is a handle on which a cutting part in the form of a metal crescent with a pointed end is attached. By the way, this model, which first appeared in the USA in 1942, is still recognized as the simplest and most ingenious invention of mankind. The P-38 can opener was created by engineers at the Chicago Life Support Research Laboratory. It was intended for soldiers in the active army, whose main diet during World War II consisted of 80% dry rations. Despite the rapid technological progress of the second half of the 20th century, this knife remained in service with the American army until 1981, when cans with a special tongue on the lid appeared - as soon as you pulled it towards yourself, the cans opened by themselves.

So to regular can opener open a tin can, place it on a table or other flat and durable surface, place the tip of the cutting part close to the inside of the side, then, holding the knife by the handle with one hand, apply a gentle blow to it with the other. Next, you need to push the tip of the knife deeper into the hole formed, then rest the opposite end against the lid and gently press on the handle. As a result of this movement, a force is created at the end of the knife equal to a pressure of 3 tons per 1 square millimeter. Thanks to this, the thin sheet metal lid can be cut very easily. Having opened one section, you will need to move the knife a little forward and cut through the next fragment of the lid in the same way. Moving in this way in a circle, they cut through the entire lid, with the exception of a small section, after which the lid is folded up. During this operation, you should be very careful not to injure your hand on the sharp edge of the tin sheet.

There is a can opener of a more complex design, the use of which makes the task of opening a can easier. Back in 1878, the first device of this kind appeared. It was a kind of compass, which with one leg was stuck in the center of the can, and the second, equipped with a sharp cutting wheel, moved around the perimeter. It was difficult to use, so designers constantly improved such knives. The result was a knife with a gear, which was driven by a special handle. Its purpose is to rotate the jar as the lid is opened. They use it this way: the protruding rim of the can is securely fixed between the gear and the cutting part of the knife, and then they begin to rotate the handle. This method requires much less effort, and the cut is more even.

Not long ago another one appeared type of can openers - electric. With their help, you can open any jar in a matter of seconds. In this case, you don’t even have to worry about keeping the container in the desired position. Since this is achieved due to the built-in magnet, and the can itself is securely clamped between the gear wheel and the knife blade. When using such a household appliance, you need to be careful not to injure yourself. In addition, different models have their own characteristics, so before starting work it is better to carefully study the attached instructions.

But what if you don’t have a special device at hand? There are several ways to open canned food without using a can opener. The most basic one is to use with a regular knife. Using its tip, they punch a hole in the jar, and then simply cut the lid along the rim. This does not require a very sharp knife, but the steel from which it is made should preferably be hard, otherwise the product will have to be thrown away after the procedure.

There are more exotic options, the possession of which will be useful for lovers of travel and country walks. If even the most ordinary knife is not available far from civilization, then you can open canned food using a natural stone. To do this, you need to find a hard rock boulder with a sufficiently large and flat surface.

Great a concrete slab will do, if she is nearby, of course. So, turn the jar over, place the lid down on the stone and, pressing on it, make circular movements. After some time, the jar will open by itself. The main thing here is not to miss the right moment, otherwise the contents of the jar will end up on the stone. The point is that in the factory, the cans are closed by simply folding them over, resulting in the same rim around the perimeter of the can. If you grind it off, the lid will fall off by itself.

And finally, really primitive way– arm yourself with a stone, place the can on its edge, and deliver a gentle blow. As a result, the jar will bend and the lid will crack, after which it will be possible to use a flat object to widen the hole and remove the contents through it.

It would seem like a far-fetched problem to open a tin can with your bare hands. But, according to the law of meanness, there are always situations when just such a skill would be very useful. Although the videos in this post will seem a little strange, even epic, their usefulness cannot be ruled out. As they say, who knows?

The author of all videos is an experienced “survivalist” - Grigory Sokolov. He became famous for his simple video tips for those who are interested in the possibility of life in the forest. In addition to non-standard methods of making fire, options for making housing, obtaining food and drinking water, you can find life hacks that are quite useful in ordinary life. For example, how to open canned food without special kitchen tools, namely with your bare hands.
