A cooler bag is an indispensable thing, especially for those who love to travel. In stores, such a pleasure costs a lot, but there is a very affordable alternative - a do-it-yourself thermal container. You can make such a bag quickly, and most importantly, for free. Outwardly, it will look like a regular one, and from the inside it is sheathed with a heater that will not let the cold out and not let the heat in. A little time and effort spent - and you have in your hands a thermal refrigerator that is not inferior in quality to purchased models.
Refrigerated portable compartment: what is it?
The cooler bag is a relatively modern product. This is a container or bag in which a cold accumulator is placed to maintain a low temperature inside the container and preserve perishable products.
The difference between a thermal container and a conventional refrigeration unit, which is in almost every home, is the absence of a special cooling device. Therefore, it will not work to store food in a thermal container for a long time, they will still deteriorate. Youyou can put a chilled product in such a bag, and it will be able to maintain its temperature for quite a long time. The foam and thermal reflective layer will help slow down the cooling process.
It's good if you have a large cooling bag where you can transfer all the food from the refrigerator when you defrost it in the summer. Do-it-yourself foam container does its job perfectly, and you can place not only cold foods, but also hot foods in such a container in order to slow down cooling.
Thermal bag from scratch
You can assemble a thermal container with your own hands from improvised materials.
When examining the finished product in the store, you should have noticed that the bag itself is soft, and its inner half is covered with insulation. Regardless of the type of mini-refrigerator, be it a fabric bag or a plastic container, its inside is lined with foam or its analogues, which plays the role of a layer that saves heat or cold.
Let's figure out how to make a thermal container and what is needed for this.
Materials and tools for construction
What do you need to work? To make a thermocontainer with your own hands, you will need:
- box or bag;
- foam;
- foam;
- adhesive tape;
- threads;
- scissors;
- cardboard.
Step by step guide to making
Getting started, prepare your bagor a box that you transform into a thermal refrigerator. It is better to take a light-colored bag or box as a container: it will heat up less. Cut out the desired shape and size of foam pieces that will serve as the heat-retaining layer.
After cutting out the foam blanks, put them in a bag and fasten them together with double-sided tape. All parts must fit snugly together, otherwise heat will flow inside the mini-fridge. Before inserting the foam sheets into the box, it is better to wrap them with tape, so the material will not crumble, and it will be easier to insert it into the bag.
Additionally, the styrofoam cube can be turned with a thermal reflective sheet, which will help keep the cold inside longer. This bag can carry not only chilled food, but also warm prepared meals to keep them fresh and looking good.
Do not forget that in such a container, in addition to the walls and bottom, there must also be a lid. It should fit snugly into the foam box. It is not advisable to make cuts for fingers in such a cover, because warm air from outside will flow through them. In this case, it is better to stretch the thread through the foam, attaching pieces of cardboard to the surface of the foam at the intended puncture points. Such a move will prevent rapid damage to the foam. This is how you can easily make a good thermal container with your own hands. The photo clearly illustrates the success of the work.
Functional bag as a result of work
Assemble such a thermal bag really in just 10 minutes. The thermal bag works on the principle of a thermos - it retains heat (cold). It cannot produce cold on its own, for this it will be necessary to place cold-producing cold elements for thermocontainers made by oneself inside the bag.
Even a child can cope with such work, but in the end you have a mobile product cooling device. True, this does not work for long, over time the container still loses its tightness, so if you are going on a long journey, you cannot do without coolers, or buy a mini-fridge in a specialized store.
Design nuances
If you glued cubes or boxes as a child, then you will be able to cope with the task and figure out how to make a thermal container with your own hands without any problems. By following the instructions and making the portable mini-fridge right, you will be able to get a full-fledged storage space for perishable products that keeps cold (warm) up to 24 hours.
You can design a large thermal bag if you go on a long journey and are worried about the quality of the products. The handmade thermal container exceeds all expectations, especially if you pay attention to the discrepancy between the price and quality of purchased models of coolers for food and drinks.
By making such a container, you will always have a supply of fresh and chilled food on hand, and save money.
This bag is convenient to take with you on the road, leavingnature or lake. Even going to the beach, you will always have cool, and most importantly, fresh and edible food and drinks.
