On the inside of the lid there is a special polymer coating that acts as a gasket. Under influence high temperature it expands and seals the jar tightly. As the temperature decreases and as it cools, the top of the lid pulls inward, which is accompanied by a slight click. As a result, a vacuum effect is created in the jar.

Many housewives know how to roll up jars. During the season of ripening vegetables and fruits, the production of pickles, jams, and various dishes begins, which are rolled up with iron lids. This increases the shelf life of products and allows you to eat delicious food from independently grown fruits. But not everyone knows how to close jars correctly.
How to roll up jars correctly: basic methods
Sealing uses metal lids that are tightly screwed to the jar. There are 3 options for closing with different devices.
Manual mechanism
The manual seaming machine was one of the first to appear. It is found in most homes, where it has often been stored and used since Soviet times. When using a screw device, the process is completely controlled by a person, but requires force to be applied to the lid. This option is one of the most difficult, since practical knowledge is required.
How to properly roll a can with a manual machine:
- It is necessary to place the lid on the jar, press it with the device, and roll it up in a clockwise circular motion.
- Making several turns, the handle is rotated to reduce the diameter of the roller, then the process is repeated.
- Care must be taken not to damage the jar, but it must be screwed tightly to ensure a tight seal.
The main advantage is low cost and ease of use. The work requires a lot of effort. Among the disadvantages is the need to expend energy, since there are modern models that do not require this.
Snail key
It is an ordinary screw machine, but does not rotate along the central axis. Instead, a spiral is created on the plane of the device. The mechanism of operation is similar: the lid is pressed tightly with one hand, and rolled up with the other, guiding the device in a spiral. For a tighter twist, the handle is rotated clockwise, reducing the diameter along which the mechanism moves. When the probe moves the shortest distance to the center, the handle is unscrewed counterclockwise and the machine is removed.
The advantages are ease of use, but the main disadvantage is the time required to seal one can. Despite the ease of use, it is necessary to check the quality of the work performed to avoid loss of products.
Semi-automatic
It is a regular seaming machine with horizontal and vertical handles designed for holding and screwing the lids. The latch has a thread along which the mechanism rotates, pressing the metal against the glass. To tighten it, just install the device and turn it until it stops.
The advantage of semi-automatic machines is the speed of processing cans: less than one minute is enough for each one. Disadvantages - high cost, need for adjustment. Although the devices are sold adjusted, the balance is lost after 200–250 cans. Re-tuning takes a lot of time, but is not always successful, which makes it necessary to purchase a new machine.
Machine
A fully automatic machine is an easier-to-use version of a semi-automatic machine with a more complicated mechanism. Has two handles used for twisting. How to seam cans with a seamer:
- The device presses the lid tightly.
- The key is turned 7–9 times until a characteristic click is heard. There is no need to turn the screw during seaming.
- To remove the device, you must turn the key completely in the opposite direction.
The advantage of an automatic machine is its ease of use, long-term operation without breakdowns. Disadvantages - high cost, the need to unwind the device for a long time in both directions.
Seaming Vacuum Pump
The vacuum pump allows you to roll up the lid without using a special machine. To use the device, you need special covers that are inserted from below. Then the mechanism is put on the jar so that the lid clearly coincides with the neck. To complete the process, just pull the piston: the lid will press tightly, pushing away the air.
The advantage of the pump is its quality and speed of work. Disadvantages include cost and the need for skill.
How to check for leaks
To ensure the quality of the seaming, you must perform the following steps:
- After rolling up the jar, turn it over and check if the lid is leaking.
- Take the jars to the room with room temperature, place it upside down on a blanket, towel or blanket.
- Leave the containers for two days. Check periodically for any wet marks on the fabric.
- After 48 hours, make sure that the lids are not swollen and that cracks or chips do not form on the jar.
If everything is in order, send the jars for storage.
How to Seam a Can without a Seamer
To roll up a can, you don't have to use a machine. The first option: use the vacuum pump described above to store food, although it is more expensive than conventional devices.
The second option is to use jars and screw caps. The sterilized container is filled with the necessary products, covered with a lid, which is tightly screwed until it stops. This option is not so reliable, but easy to implement. But is it possible to seal jars with screw caps? Technically, no, since special machines are used for seaming. Despite this, the result is almost the same.
How to properly seal jars with screw caps
To properly twist pickles or jam you need:
- Make sure the quality of the lids and jars, the absence of mechanical defects and other undesirable factors.
- After checking the parts, sterilize them to prevent uninvited guests in banks.
- While the lids and jars are sterilizing, prepare the dish you plan to store.
- Fill the containers with food, close the lids, screw tightly.
After checking the tightness, send the jars for storage.

How to close screw top jars
Screw caps are perhaps the fastest and most reliable way close home preparations for the winter. But there is a small drawback - not every jar is suitable for such a lid. A mandatory condition is the presence of a special thread on the neck, on which, in fact, the lid will be attached. Such carvings, for example, are found on jars of store-bought preserves. How to properly close jars with screw caps? The technology itself is incredibly simple. To begin with, like regular ones, these caps need to be thoroughly boiled. Otherwise, mold may appear on the workpiece during storage, for example, on jam. Then place the cooled, dry lid on the jar and press down lightly. Turn it clockwise several times until it stops.

How to close jars without lids
Today it’s hard to believe, but tin and especially plastic lids became common among housewives not so long ago. But home preservation, as you understand, existed long before their appearance. What did they do to prepare for the winter in those distant times? As a rule, in Rus', vegetables were pickled and fermented in large wooden barrels, which were stored in cold cellars. Therefore, there was no need for tin lids as such then. But with the development of industry and urbanization, many housewives were faced with the question of how to close jars without lids. For a long time, wax paper soaked in alcohol and thin twine were used for this purpose. This knowledge can also be useful for modern women, since sometimes ordinary lids are not at hand, and vegetables/fruits for preparations begin to quickly deteriorate.
How to cover jars with paper
To begin with, we note that the paper method is short-lived and at the first opportunity it should be replaced with canning with tin lids. First of all, you need to take very thick paper and cut out a circle from it, the diameter of which will coincide with the diameter of the neck. This paper must be soaked in rum or pure alcohol and covered with it. This method is good for boiled jam or preserves. But it is better to cover cucumber-tomato preparations with paper and cellophane. Cellophane can also be replaced with cling film folded in several layers. First, we wrap a piece of plastic bag around the neck, pulling it quite tightly to achieve a tight seal. We secure it on top using a rubber band or regular thread. After this, put a sheet of thick paper and form a lid from it. The paper is needed in order not to tear the cellophane during transportation of the workpieces. The paper cap should also be secured with thread or an elastic band.
