The invention relates to an insulated bag which is used for long-term preservation of the initial degrees of pre-chilled alcoholic and non-alcoholic beverages in metal kegs (kegs) made of stainless steel or aluminum and for carrying these kegs and which, with the further development of insulating materials, has highly resistant outer and inner insulating layers and for Beverage barrels (keg) was developed.

State of the art

Portable insulated containers of various shapes and sizes that are used to maintain the temperature of cold beverages and ready-to-eat foods are now in widespread use. Products used in outdoor activities such as picnics and referred to as "cooler bags" are made from a hard composition such as styrofoam in the casing or in the form of an enveloping bag or pouch with a soft exterior composition. Generally, such products are designed to hold the prepared food and beverage products and maintain their temperature for a period of approximately 6-8 hours. To maintain the condition of pre-chilled food and beverages, a common practice is to place ice packs inside the container to increase and prolong the thermal benefits.

Comparable products on the market that are used to maintain temperature, particularly in the field of beverage consumption, are made of neoprene or injected polyurethane materials that contain synthetic fabrics, soft or hard covers, or Styrofoam insulation materials. The heat retention time of products made of such insulating materials is short. The internal parts or compartments of the products used to keep the pre-chilled beverages cold in the kegs are supported by external cooling modules or chemical or natural ice. Due to the melting of the cold packs used to keep cold and the ice, the temperature is only maintained for a short time. In addition, the use of ice packs or ice packs to keep cool during transport also adds extra weight. Ensuring such cooling is a disadvantage in terms of both time and user friendliness.

A utility model application was found in the literature under the title "Carrying bag developed for drinks" and the number TR 2015/03795. This invention relates to a carrier bag designed to make the beverages sold in packages made of glass, plastic, metal, etc. more convenient and easy to carry while also keeping them cold when needed. The designated tote consists of a main body made of styrofoam (foam) material in which the beverage cans/bottles are positioned and the cover made of styrofoam (foam) material over the main body and carrying straps that allow for transportation. The heat resistance of products made of Styrofoam is short.

Another invention is the European patent application DE 102009048164 (B4 ) entitled "Box for the transport of refrigerated products". The invention referred to relates to a dry ice refrigerated container for transporting foodstuffs with a storage area for accommodating the refrigerated products and a refrigerated space which is in thermal contact with the storage area for accommodating the storage area, characterized in that between the storage area and the refrigerated space, between the refrigerated space and the Storage area is a thermal mat made of a flexible plastic, especially neoprene. The fact that products made of neoprene material have a low heat retention time and the use of chilled ice to extend the cold retention time is disadvantageous in terms of both time and user-friendliness.

Proceeding from this, due to the disadvantages described above and the inadequacy of the existing solutions in this respect, it is considered necessary to carry out a further development in the respective technical field.
