DIY cooler bag and thermos bag

Summer is a wonderful time when many people go out in nature with their families or friends. Many people face one problem: how to save products. A thermos bag and a cooler bag can easily cope with such a task.

Summer residents are not used to leaving all their salaries in stores. Many things in the countryside are done by hand. Here you can make a refrigerator bag yourself. However, it is first worthwhile to understand what a miracle refrigerator is that can help many vacationers.

A refrigerator bag is an item that will help keep food fresh for 12 hours. Externally, the bag is no different from its other "brothers". However, this product still has a little trick.

For many people, with the mere mention of the phrase “cold accumulator”, one picture arises in the head: you need a special device that will perform the function of producing frost.

However, the cold accumulator can be made from improvised materials that are present in all homes.

To get it, you need to pour water into ice molds and put them in the freezer. As soon as the water hardens, it will be possible to start making ice packs.

Put ice cubes in the latch bag, close the bag. The second package will protect against leakage, so the first package will have to be put in another one.

For their manufacture you will need the following:

• empty packagingwhere there were carbonated drinks;
• water (the amount of liquid depends on the size of the bottle);
• salt (6 tablespoons per 1 liter of water).

It is necessary to make a strong solution with salt. The salt must be dissolved in water, after which the resulting solution should be frozen. Salt will not allow ice to melt quickly. This means that the bag will hold the cold in itself for much longer.

This method of creating a refrigeration unit is recommended for families with small children. In the inside of the diaper, pour water. You should wait until the liquid is well absorbed in the diaper itself. A baby hygiene product will need to be cut. The gel mass should be laid out in a plastic bag with a fastener and put in the second bag. After that - send the finished package to freeze.

It is created on the basis of saline solution. The solution should be concentrated, which subsequently will increase its volume to 3 liters. In the diluted 3-liter liquid, add wallpaper glue or gelatin. Place the gel mass in the prepared container and put into the freezer. The gel battery melts much longer than regular ice.

Knowledgeable summer residents in their suburban areas use such a tool as fertilizer. From such an assistant in the country, it is easy to get a high-quality cooling element.

From nitrate, air temperature can drop by twenty-three degrees.

Two ingredients (water and ammonium nitrate) are taken in equal proportions. Pour fertilizer into the prepared bottle and dilute with water. The battery is ready.

There is a second option for creating this cooling element. Nitrate is added to frozen water. The cooling effect of the battery on the fertilizer thus increases in time several times.

Chilled foods will not warm in the foil bag, and hot snacks will not cool. Any building materials store always has it in its assortment.

Aluminum or metallized foil and keeps the temperature in the bag. Such polyethylene is available with single or double-sided coating. Double-sided foil polyethylene has the best characteristics.

Based on the listed refrigeration tools, you can make a portable refrigeration chamber.

The insulating properties of the foam allow many craftsmen to use it to create a portable refrigerator. Polyfoam is produced in different types, so some characteristics are different. DTo create a thermal container, a regular foam plastic consisting of pressed small granules is suitable.

It will not replace foil polyethylene due to its thickness and lack of plasticity, but it is quite possible to make a container for provisions that can fit in the trunk of a car.

So, you need to prepare the following:

• Styrofoam;
• plywood;
• aluminum tape;
• furniture hinges for a cover;
• necessary locksmith tools.

First you need to make a box of plywood. What size and shape the box will be - it is up to the master to decide. You will need to attach the lid to the drawer with hinges. The corners and ends of the resulting box are places that must be processed with aluminum tape.

Polyfoam is cut to the size of the future container. You will need to insert the finished part inside the box and stick it. Cover the box with foil and reinforce with tape.

On the box lid - apply polystyrene and stick it. The dimensions of the finishing material on the lid should be determined taking into account the walls of an almost finished box.

Window insulation tape will make the product airtight if laid along the perimeter of the lid.

At the bottom of the finished box you need to put the cold accumulators (which were already mentioned above).

A personal car has long been considered not a luxury, but a convenient means of transportation.If the summer cottage is located not very far from the city or the family is small, then they do not make large stocks of products for a country house. It is more difficult for those families who have children, elderly parents, if vacation in the country is planned for a certain period.

How to make a refrigerator box, you can learn from the previous part. It is worthwhile to dwell in more detail on a portable refrigeration device.

Need to cook:

• foil polyethylene;
• aluminum tape;
• a sports bag.

A sports bag usually has a rectangular shape.

There are two ways to make parts from foil:

• Make one blank for the size of the bag (if the size of the polyethylene allows).
• Take the dimensions of all the walls of the bag separately and cut them out of foil.

The pattern of the cover of the refrigerator in size should be smaller than the bag. This will allow you to easily insert the cover into the bag.

In the first version of the manufacture of the refrigerator, you need to fold the finished parts - as a designer. You need to take ordinary or special tape and strengthen the corners of the foil cover.

The second version of the cut parts is folded in parts. Adhesive tape is applied to the side seams inside and out.

The walls of the container must be firmly in contact with each other, otherwise the "thermos" will not keep the created microclimate.

If the thermal foil does not bend well, then the lid can be made separately. You need to cut it from the base and attach it to the top of the bag with tape.

Given the recommendations, you can make a cooler bag at home without any problems.

However, few people know how to multiply the effectiveness of a portable refrigerator:

• The first tip is useful for those who travel a lot by car. The blanket will be a great helper, allowing you to keep the desired temperature in the bag. Just wrap a portable refrigerator in it.
• Direct sunlight will degrade the effectiveness of the bag. It should be kept away from sunlight.
• The best place for batteries is the bottom of the bag. If, in this position of the batteries, the products do not fit into the bag, then there is a fallback: they can cover the products.

• Perfect if the products are chilled.
• The denser the foods will lie to each other, the slower the temperature inside the refrigerator will rise. Empty space in the bag must be filled with any container with water or a folded blanket.
• Before arriving at the place of rest, it is often better not to open the bag (if this is not possible, you should do this as little as possible).

A bag designed to create a small refrigerator should be chosen first. The beach option is also suitable. Only then purchase material for a refrigerator cover in the store. Decide on the amount of thermal foil. Cutting out the details will need to be done without a pattern of pens.

After cutting it will turn out:

• walls - 2 parts;
• bottom - 1 part.

If the bag does not have a large round bottom, then the foil walls can be connected using a sewing machine (if the thickness of the finishing material allows). In other cases, you need to use tape.

An equally interesting version of the refrigerator where you can cool drinks is obtained from the following materials:

• A bucket where there was paint (from any material).
• Mesh of metal (carry out the calculation yourself).
• Small cable ties (approximately 30 pieces).
• Masking tape.

The sequence of all work:

• Eliminate old paint in a bucket and paint it white with a spray can.
• On the container body, draw three rows of circles with a diameter of 3-3.5 cm, you need to arrange them at a certain distance from each other.
• Using a hole saw, drill holes along the marked circle lines.
• Now you need to prepare compartments for drinks.An ordinary bottle (jar) 2-3 times wrap with a fine mesh, but not very tight. Layers need to be fastened with screeds. Outwardly, the mesh should resemble a cylinder - the size of a bottle.
• A towel made of terry cloth should be put in the cylinder. At the bottom you need to put a piece of foam or absorbent tissue.
• You can place several cells in the bucket. This will be the parameter by which you can determine how many bottles will be cooled. If you plan to use the bucket for cooling, you need to moisten it with water.

The white paint that covered the walls of the bucket will reflect the sun's rays, so that the temperature inside the dishes will not rise. Water will evaporate through the holes, due to which the desired microclimate will remain.

Most of all about karemat people know who are often on hikes. Karemat resembles a rug with good thermal insulation. It is used as bedding in a sleeping bag.

First you need to prepare a mixture of water and ammonium nitrate. The latter can be taken with you on a dry trip. The cap in the bottle must be tightened carefully.

Karemat will act as a heat insulator. It needs to be turned into a pipe. Inside, drinks and a cold battery should be put. The holes in the pipe should be plugged with clothing (this will keep the temperature in the interior of the refrigerator).

Accuracy in handling ammonium nitrate will prevent fires and explosions. Ingestion can cause severe poisoning.

A picnic in nature is an event that will relieve work fatigue in adults. Children will play enough in the fresh air and taste the delicious stocks made by mom and dad. And the refrigerator, made by hand from improvised means, will fulfill its functions and save the family budget.
