On the bag, a carrying handle or a lanyard may be attached. That ’s how the cool bagcomfortable to wear. Another use is the transport of hot food, so that there are different uses for the products.

The coolbags: Perfect for cold and hot dishes

Most coolers are not only used for food cooling but also for keeping food warm. The „Aosbos Waterproof Lunchtasche“ is suitable for both cold and warm dishes. Thanks to the dimensions of 24 cm x 15.5 cm x 18 cm, lunch will take place in the interior. The bag is equipped with a practical handle and a zipper. In the selection, the size is an important criterion. The „MIER Portable Heat Insulated Cooler Bag“ has an internal volume of 9.45 cm x 5.91 cm x 3.15 cm. You can store a small lunch box and a beverage can indoors. The all-round closure allows the bag to open, with a particularly large opening. Filling the cooler bag is straightforward. The cooling batteries must often be purchased separately. However, they can already be included in a set. The classic shape of the batteries is cuboid. The interior of the rechargeable batteries is filled with a gel or salt water. The gel must have a high heat storage coefficient. You put the battery before use in the freezer compartment of the refrigerator or in the freezer, During the cooling process, the coolant freezes and the battery puffs up slightly. Since the water is not replaced, a preservative was added. It prevents the rotting of the water and the battery can be used for years.

The functional principle of the refrigerated bags

The basic idea of ​​the cooler bag is that there is no temperature exchange between the interior and the exterior. Once a certain temperature has been established in the interior of the bag, it is retained. If you would like to transport cool food, it will be put into the bag in a cooled state and a cooling battery will additionally ensure the stability of the temperature. As a rule, the temperature is cooled down even further by the battery. If you are transporting hot food, the food will give off heat that warms up the interior. Since the heat can not escape to the outside, the food stays warm. Please note, however, that despite good heat insulation there is always a small exchange of temperatures. The quality of the insulation determines how long the food is kept at the desired temperature. Larger coolers or coolers are provided with automatic cooling and can be connected, for example, to the cigarette lighter in the car. The built-in cooling system ensures reliable cooling of the food while driving.

Why do I need a mini cooler?

Food must be kept cool so that no harmful substances form. Sausage should have a temperature of +4 to +7 degrees Celsius. Outside the refrigerator, this temperature can not be maintained. Cheese, sausages and other sensitive foods can not be taken to work or school. In the mini cooler, however, the food is well kept and tastes perfect as a snack. They use the bag not for the daily lunch but also for the trip to the lake. After a refreshing dip in the water, hunger increases and it’s time for a small meal. Thanks to the compact shape of the mini cooler bags, they are used on bike rides, on hikes and for the weekend trip. When using, please note that the food must always be sufficiently cooled, which is why the bags should not remain in the parked car, for example, on hot summer days. Before you use the containers for hot food, you must make sure that the bag is suitable for this use. The material must be heat-resistant, then this twofold use is nothing in the way.
