Very often in everyday life, a device such as a thermos bottle is required. It is used to store food in hot or cold.

Refrigerator bag with own hands

You can, of course, buy this little thing in the store. However, this may not be possible for others. But there is a way out! The sewn bag-refrigerator by its own hands is almost inferior in functionality to the factory product. After all, the main element of this device is the isolation of the interior of the object from the effects of external temperatures. And an excellent material for achieving these goals can serve as a foam plastic, which lays out an ordinary shoebox with a lid or a cardboard case from the laptop. It is made such a bag-refrigerator with their own hands quite quickly and without financial costs. One drawback of this little thing is a small inner volume.

In order to be able to take out more products on the nature, you can use another way of making it. The master needs a capacious bag, you can take a normal sports or backpack. Then, from the old down jacket or blanket, a backing heat insulator is cut out and sewn, which should easily fit in.

How to make a bag-refrigerator with your own hands

For greater aesthetics and improving the quality of things one should buy foam polyethylene with glued foil. From the insulation cut "cross", consisting of four connected rectangles. The bottom of the bag is laid in the base, the sides adjoin its sides. The pattern is made a bit less than the volume of the bag itself so that the inner box of the heater can easily enter into it. The lid is best cut individually, pasting it at the very end, since the foamed polyethylene badly bends. The remaining rectangles are folded in half and installed on the corners-joints, thereby creating a second layer of insulation.

The fastest and easiest way to make "thermoprene"

Our grandmothers offer in the old books of advice for young housewives its own version of how a refrigerator bag is made by oneself. Two containers are put in the bag, you can take even ordinary pots. One must easily enter the other in such a way that a hollow space remains between the walls. Between the bottom and the walls of the inner tank and the outside, a gasket is made of insulating materials: wood, polystyrene, fluff. Previously, conventional sawdust or shavings, hay or straw, crumpled paper were widely used . The products are already frozen or heated up to the desired temperature (either one or the other). For better effect, it is recommended to put inside the "refrigeration unit" - a piece of ice in a dense package. And it is best to use metal cans from under beer or Coca-Cola, in which metal parts are pre-placed: nails, bolts, nuts. Then water is poured and the whole structure is frozen. Such a device will give its cold for a long time, and even during defrosting it will not flow.
