How to open canned glass bottles, how to open glass jars of canned fruit

We usually need to use sealed jars to store jam and pickle some cooked food, sometimes we need to store it for several months before opening, but once the time has passed, our sealed tubes are not easy to open. So what should we do if we encounter a situation where the sealed jar cannot be opened? Next, I will give you a support and teach you how to open it.

Method 1: We can pry along the edge of the bottle cap and use a sharp object such as a knife or scissors to keep the atmospheric pressure inside and outside the can balanced.

Method 2: Then we can wrap a paper towel with stainless steel and keys to increase friction, and then pry the cap along the edge of the bottle mouth to let the air enter the can and it can be opened.

Method 3: We can find a sharp object or a knife, poke a hole in the lid, and once the air pressure inside and outside the bottle can be balanced, it will be easy to open.

Method 4: We can tilt the sealed jar upside down and then grab the sealed jar and slap the bottom of the jar, and knocking the lid also has the effect of breaking the intermolecular force between the jars.

Method 5: We can use the hot hair dryer at home to repeatedly heat the cap from far to near, or we can open the sealed can.

Method 6: I can soak the sealed jar in the pot, and then heat it with 80 degrees of hot water for half a minute, but pay attention to the heating time should not be too long or you can pour the lid with hot water for a few minutes and then pull the lid hard, and the lid can be opened.

Tips for opening the lid of a can easily:

1. Hot water:Because cans are kept for a longer period of time, they are usually very tightly sealed, so they are not easy to open. We can open the can lid according to the principle of thermal expansion and cold contraction.

Pour some boiling water into a bowl so that it is deep enough to cover the cap. Then put the canned bottle cap down into the water, wait for about half a minute to take it out, the bottle mouth is not tight after the heat expands, and you can easily unscrew the cap.

2. Slapping:This is one of the most common and easiest ways for us to turn the can upside down, pat the bottom of the can with the palm of our hand, and after a few consecutive beats, the can will loosen, and then we bring a rag or gloves to twist the can lid to easily unscrew it.

3. Sharp knife:When you really can't open it, we can also use violence, otherwise you won't be able to eat delicious things. We can pry it with something.

Than a sharp knife, slowly pry along the edge of the cap to let air in, and it will be easy to open the cap. If the lid of the can is not very thick, we can find a needle and puncture it, so that after the air is released, the air pressure inside and outside is equal, and we can easily open it. However, the canned food opened in this way should be eaten immediately.

4. Tape:I can't imagine that you can open the lid of a can without any weight tape, and the specific way to do this is to choose about 25-30 cm of tape. Then glue the tape to the cap of the canned bottle, paste it counterclockwise here to remind not to stick the glass bottle together, about halfway through, fold the tape in half to make a handle.

Then hold the upper edge of the glass bottle with your left hand and the handle with your right hand, and with a horizontal force, the can will be opened. Isn't it amazing, you can try this method next time you can't open the can.

Pat the bottom of the jar and open it again.

There are a few principles and steps required to open a canned glass bottle:

1.First of all, take a rag with a thick handle and cover the mouth of the glass bottle to make the temperature on and around the glass bottle more even, and prevent the glass bottle from bursting when opened.

2.Use a professional can opener, place it on the mouth of the can, hold the vertical ruler can opener so that it is perpendicular to the glass bottle, and then turn it so that its blade rotates along the glass bottle, as long as its blade is smoothly rotated along the edge of the glass bottle, the glass bottle can be broken.

3.If the can opener malfunctions, a small plier or adjustable wrench can be used to grip the lid of the glass bottle tightly and twist slowly until the cap is removed.

4.Finally, slowly pull the cap apart by hand to prevent the cap from popping out and causing damage.

In conclusion, it is important to be careful when opening canned glass bottles, to take your time, and with the proper tools and steps, it can be done easily.

If you want to open the glass bottle easily, you can turn the bottle upside down and pat the bottom of the bottle with the palm of your hand.

Turn the bottle upside down and slap the bottom of the bottle with your palm, the bottle body will be impacted, the air inside will **, and the cap will be loosened. In this case, in order to prevent your hands from slipping, cover the bottle cap with a dry towel and twist it in a counterclockwise direction. If you encounter a can that is difficult to open, you can use a professional can opening tool that simply attaches the cap opener of the appropriate cap size to the lid and rotates it counterclockwise.

Glass bottles and jars are transparent, easy to clean, chemically stable, do not pollute the contents, high air tightness, good storage performance, rich and colorful decoration, can be used many times, and the raw materials are abundant. However, glass bottles and jars are easy to break, and the weight-to-volume ratio is large.

Other ways to open the lid

1. Soak in hot water.

Use the principle of thermal expansion and cold contraction to open the cap, and place the canned bottle upside down in a bowl with hot water, so that the water engulfs the entire cap. After 20 seconds, take out the canned bottle, wipe the cap dry, and easily open the cap with a little force.

2. Open the cover with adhesive tape.

Stick about 25-30 cm of tape to the cap of the canned bottle, taking care not to stick the glass bottle together. When you are halfway through the conversation, fold the tape in half to make a handle. Then hold the upper edge of the glass bottle with your left hand and pull the handle firmly with your right hand to open the can.

The glass jar has the following ways to open the bottle with a head

1. To open a delicious can, you can first turn the can upside down, pat the rest of the food twice, and then open it again.

2. Blanch the cap with hot water, put the cap of the canned food and bottle downward, use the kettle or put it into a small basin or other utensils, use the air in the canned bottle to expand, and take it out after about 3 minutes to unscrew.

3. Use a screwdriver to pry the edge of the cap loose, and it can be opened when there is a sound of air entering the bottle.

4. Using a lighter to burn the bottle cap is also the use of the principle of "thermal expansion and cold contraction". If you don't have hot water and hot water utensils around, you can use a lighter to heat the bottle cap, and as soon as the lighter is close to the bottle, the bottle will make a "swish" sound, and after more than ten seconds, put on a towel and unscrew the bottle cap. Reminder:

It is easy to burn your hands when you bake the bottle cap with fire, and the danger is high, so you should pay attention to safety.

There are two kinds of canned bottles, one is tinplate, the other is glass jar, the two opening methods are different, and the following tells you how to open two different cans.

Tinplate canned food opening method.

1.First, soak the tinplate canned fruit in hot water for 3-5 minutes, so that the temperature of the gas in the can increases, and the air pressure increases, which is the principle of thermal expansion and cold contraction. Turn the canned fruit bottle upside down for a while, wait for the liquid inside to destroy the vacuum of internal and external pressure, tap the bottom of it with the palm of your hand, and then gently pull the pull ring, it is easy to pull away.

2.To open the canner, separate the handle and clamp the fruit can to be opened with the head, and turn the knob to open the tin can. Remember, when you turn the knob, you can only rotate clockwise, not counterclockwise.

3.The Swiss Army Knife has a special tool for opening fruit cans, hook the outer edge of the can with a hook at the bottom, and press down the lid of the can with the front edge, as if there is a circle of grooves on the edge of the top cover. Press it in and push it forward, taking care not to press the head into it, otherwise there may be wear and tear.

The bottom hook hooks the outer edge of the can, and the front edge of the can is pressed down forcefully, as if there is a circle of dimples on the edge of the top lid. Press it in and push it forward, taking care not to press the head into it, otherwise there may be wear and tear. This tool is also very easy to use.

4.Household kitchen knives and pliers, use a kitchen knife close to the side of the handle, put it in the middle of the canned fruit, and then press down gently, it is the knife head into the can, gently push the handle, so that there will be a gap in the can, and then use pliers to pull the iron piece at the opening, so that it is opened, but be careful not to hurt your hand.

5.Screwdriver and hammer, find a household screwdriver, preferably flat, along the depression of the lid of the fruit can, gently hit the handle of the screwdriver with a hammer, and hit it round so that it opens.

Although the above opening method is really a small black jar of crystal jade, as long as it is a tinplate can, it can be opened, and the glass jar is opened.

How to open a sealed can (common sense).

1) Put some hot water in a bowl and turn the can upside down in the water. After about 10 minutes, take it out again and it will be easy to open!

2) Use a sharp object, pry under the lid, and hear a "flutter" sound, it is an air leak, and it is easy to open.

3) Turn the can upside down, and gently knock the lid on the ground with skill, and hear the click. After the sound, it means that the air inside has escaped out, and finally twist it in the opposite direction with both hands.

Tips for opening canned caps: knock the lid method, plastic wrap opening the cap method, pat the bottom of the bottle method, and hot water method.

The first trick is to knock the lid method.

This trick is very simple, but it is particularly effective, at this time we only need to hold the bottom of the bottle with our hands, and then turn the bottle upside down, knock it out a few times on the table, and then twist it with our hands, it is very easy to open the lid of the can, this method is that children can also open it, very easy, very simple.

The second trick is to open the cap with plastic wrap.

Place the can on the table, then take out the plastic wrap at home, wrap the lid completely with plastic wrap, and then twist it firmly so that the lid of the can is also clearly opened. The friction of plastic wrap is relatively large, and we use the friction between plastic wrap and the cap to make the cap easy to open.

The third trick is to pat the bottom of the bottle.

Let's turn the can upside down and hold it in our hands, and then pat the bottom of the bottle several times, this should be decided according to your actual situation, and you should also pay attention not to use too much force when shooting, so as not to hurt your hands, which will make the air pressure inside the bottle impact the bottle cap, so that the bottle cap becomes loose, so that it is easier to open it.

The fourth trick is the hot water method.

Prepare a small dish, pour an appropriate amount of hot water into the dish, and then turn the can upside down and put it in to soak for half a minute, that is, put the position of the cap in the hot water to soak. After waiting for a period of time, the surface moisture is dried, and then you can open it very easily with a slight twist of your hand, because of the principle of thermal expansion and cold contraction, the iron lid will expand faster, so the lid will become loose, and it will open as soon as you twist it.

Four ways to open the lid of a glass can:

1. Pry open with a tool: take a sharp tool and pry it at the cap, and then unscrew the cap when the air enters the can from the gap.

2. Pat with your hands: Place the glass can upside down, pat the bottom of the bottle with your hand, and then turn the glass can over and screw the cap.

3. Soak in hot water: take a basin and add an appropriate amount of hot water, soak the glass can upside down in hot water for about 1 minute, and then unscrew the cap.

4. Use a towel: put a towel at the cap of the bottle to increase friction, and twist the lid with your hand through the towel to unscrew it.

Detailed steps:

To open the cap of a can, you need to prepare: a bowl of warm water and a towel.

1. First pour an appropriate amount of warm water into a small bowl and wait for the cherry blossoms.

2. Next, take out the canned food and place the canned food upside down in warm water as shown in the figure below.

3. Take out the canned food after a few minutes of the hidden hunger bell, and use a rag to wipe the water on the can.

4. Next, unscrew the lid of the can counterclockwise as shown in the figure below.

5. Finally, you can open the lid of the can very easily.
