The refrigerator bag can help you in the summera period of time and will help out even in the hottest days. It will keep the cold of cool and alcoholic beverages, leave fresh food and will not let them spoil for a sufficiently long period of time. You can take it with you to the car if the trip is planned for a long time, or you can just take it with you to the beach. Often such bags take with them to rest on the nature with tents. This, without a doubt, is a necessary and useful thing for any person. And the most important thing is that such a wonderful refrigerator bag can be made from improvised materials. To make a bag-refrigerator with our own hands, we will need:
- A travel bag of any size (depends on what size you need);
- foamed polyethylene with a layer of foil, which is sold in almost all construction shops and buy it will not be a big problem;
- foam rubber;
- wide scotch;
- bottles of plastic;
- usual salt.
After you have prepared all the necessarymaterials can directly begin to manufacture a refrigerator bag. The first thing you need to do is measure the height, length and width of your chosen bag. Obtain the dimensions obtained and subtract from each of 4-6 cm. After that it will be necessary to tailor the basket to the dimensions of a polyethylene foam bag, which we place inside the bag. Tightly seal all joints and jointstape, so that the thermal effect is not lost! Be sure to take into account the fact that polyethylene is required for the cover of the box. To enhance the effect, you can make another box, but smaller and place it in the first one. Then we get a stronger effect and the cold in the bag will last longer. The box must be pressed tightly against the walls of the bag so that it does not hang in it and does not lose shape. The main part of the refrigerator bag is made. Now you need to make cold containers. They are also used in branded refrigerator bags, so we will do the same. Containers will serve us as plastic bottles. The capacity of the bottles depends on the size of your bag, so choose between 0.5-1 liter bottles. In the bottle, pour a very concentrated solution of common salt (6-8 tablespoons of salt per liter of water) and leave in the freezer until completely frozen. Instead of plastic bottles, rubber heaters can be used. After the bottles are completely frozen with saline solution, you can put them in a bag and use it for the intended purpose. Some tips when using1. Cold containers should be placed every 12-15 cm for better efficiency. With such an arrangement, food will remain cool for a long time. All products are individually wrapped in newspapers to increase thermal insulation. At the top of the food, put several frozen hot-water bottles with a solution of salt and a towel, and then cover it with a lid. The cooler bag, prepared by hands, can keep the cold for a whole day! It will be convenient to take it on a picnic or on a trip!
