Description

The utility model relates to backpacks and is intended for transporting goods, including foodstuffs, including foodstuffs and drinks, and other household goods.

A portable storage box is known (CN 0111674679 A, 09/18/2020), which contains a box body, a strap, a top cover. In one of the walls of the drawer body there are grooves used for the installation of drawers, and the ends of the drawers are movably located in the grooves in a plug-in manner. The number of grooves and the number of drawers match. The disadvantage of this device is that it does not provide the ability to simultaneously transport objects with different temperature conditions, such as hot and cold objects. Since the device is not capable of maintaining a certain temperature inside for a long time, and isolation from each other of at least two zones is not provided, in each of which it would be possible to maintain its own temperature regime.

Also known is a food delivery box (CN 209777246 U, 12/13/2019), which refers to transportation equipment. The food delivery box includes a body, a lid, the body has an interior space for storing food and an opening to allow food to enter and exit (the cover of the box can cover the opening), a removable heat preservation box is additionally located in the body of the box, and a heat storage material and the heating device is placed in the boxes to keep warm. The disadvantage of this device is that it does not provide the ability to transport both hot and cold goods at the same time. This appliance is only designed to transport hot food. The temperature is maintained by the heating device, which complicates the design, increasing the number of assembly operations. In addition, the product itself is not capable of maintaining a negative temperature inside for a long time. In addition, at least two zones are not isolated from each other, in each of which it would be possible to maintain its own temperature regime.

The prototype is a backpack for transporting products (CN 0201512184 U, 06/23/2010) of various temperature conditions and maintaining the temperature of products as part of the delivery, consisting of a thermal insulating box made of expanded polypropylene (EPP), which consists of compartments with internal heat-insulating shelves formed for carrying hot containers at the top, and cold ones at the bottom, while a partition is placed in the compartment, while the cold and heat compartments are separated by an insulating layer, and are closed with a lid until it stops, while the box is covered with a frame of slings that fasten on the lid and fix it with fastexes. This device provides the ability to simultaneously transport objects with different temperature conditions. However, this product limits the size of the objects that can be transported because the thermal insulation shelves cannot be moved. It is not possible to adjust the location of the shelves and carry objects of different sizes at the same time, including extra large or extra small objects. As a result, the range of transported objects is reduced and the volume available for filling is reduced.

The technical result of the claimed device is an increase in the number of goods of different temperatures of different sizes that can be simultaneously transported in the device.

The claimed device provides the ability to simultaneously transport goods of different sizes with different temperature conditions. That is, the efficiency of spending space inside the device is increased while allowing objects of different temperatures to be transported.

The achievement of the technical result is ensured by the fact that the device for transporting goods, which includes a body made of expanded polypropylene (EPP), a cover fixed on the body, and at least one partition for separating temperature zones, is characterized in that the partition for separating temperature zones is placed inside the body in guide projections made in three walls of the body.

The claimed device includes a housing made of expanded polypropylene (EPP), consisting of a bottom wall, top wall, two side and one back wall.

On the inner surfaces of the side walls opposite each other, elongated supports can be made, made in the form of protruding elements and placed parallel to the bottom. On the supports, boxes or shelves are movably placed to accommodate transported goods in them or, accordingly, on them.

In addition to the body, the device includes a lid made of expanded polypropylene (EPP), made with the ability to fix it on the body due to a tongue-and-groove lock.

The device differs from the prototype in that guide projections are made on the inner surfaces of the side walls and the inner surface of the rear wall at the same level parallel to the bottom. On the guide ledges there is a flat partition for separating the temperature zones, made of expanded polypropylene (EPP).

Case size: height from 500 to 700 mm, depth from 250 to 400 mm, width from 300 to 500 mm. When making a case of this size, it does not deform when fully loaded and retains its integrity, that is, it allows the transport of goods of various sizes, including goods of the largest size allowed for such a device. The size of the goods is limited by the possibility of carrying them on the back of a person in the form of a backpack.

On the outer surface of the bottom wall can be placed guides in the form of ledges for stacking. Reciprocal stacking slots may be provided on the outer surface of the top wall, which can accommodate the same protrusions as the stacking protrusions on the bottom wall of the housing. Stacking the device allows you to stably arrange several devices on top of each other, as a result of which even more goods with different temperatures and different sizes can be transported in them at the same time.

The body can be covered with a frame of slings, which are made with the ability to fasten on the lid and fix it with fastexes. The frame of the straps is connected to the straps and the back, designed to place the claimed device on the back of a person. The presence of a frame made of straps allows you to fix the lid most tightly, avoid its unexpected opening and ensure the tightest fit of the lid to the body and partitions to separate temperature zones. This provides an opportunity to increase the number of transported objects with different temperature conditions of different sizes. Since the tight fit of the lid ensures compliance with the temperature regime and prevents even the smallest of transported objects from falling out.

The execution of the case and cover of the device, as well as partitions for separating temperature zones from expanded polypropylene (EPP) makes it possible to maintain a certain temperature inside the case for a long time without additional heating or cooling due to low thermal conductivity and porous structure of the material. Expanded polypropylene (EPP) has the properties of shock absorption and shock absorption, has a low weight (60 kg\m3), high strength, it is resistant to aggressive environments and the atmosphere - it does not fade, does not melt, does not get wet, does not pass water, is resistant to temperature changes and humidity inside and outside. This material is elastic, returns its shape after pressing. Easy to clean with water. This makes it possible to make the case larger in comparison with other devices for transporting goods (case size: height from 500 to 700 mm, depth from 250 to 400 mm, width from 300 to 500 mm) without the threat of destruction or deformation of the case. These properties of the material also make it possible to place completely different goods in it (heavy, bulky, hot, cold, wet, loose, etc.), that is, it allows you to expand the range of transported goods and increase the number of transported objects with different temperature conditions.

Fixing the lid using a tongue-and-groove mechanism ensures a snug fit of the lid to the body. Due to this, the heat exchange of goods inside the device with the external environment is blocked, and the goods retain their temperature for a long time.

Placing boxes or shelves for goods on supports allows you to change the position of the shelf depending on the size of the goods that need to be placed on it. Thus, the space inside the device is distributed most efficiently. This makes it possible to place the largest number of objects of different sizes at different temperatures inside the device.

The presence of supports for placing boxes and their implementation in the form of protruding elements makes it possible to place objects of greater weight in the boxes. That is, it makes it possible to increase the range and number of objects of different sizes that can be transported in the device. There can be several such pairs of supports inside one housing. In this case, several boxes can be placed inside the device at the same time.

If you place boxes or shelves on which goods will lie inside the case in grooves made in the form of recesses in the walls of the case, this will lead to gradual deformation and destruction of the grooves and walls of the case, as a result of which the device will become unusable.

The presence on the inner surfaces of the side walls and the inner surface of the rear wall at the same level parallel to the bottom of the guide projections allows you to place a partition on them to separate the temperature zones. The fixation of the baffle prevents heat exchange of goods from different temperature zones with each other, and also prevents air exchange between these temperature zones and the spread of odors.

The partition is tightly fixed on the guide projections due to the fact that at least three of its edges have a protruding part, which is located on the guide projections with an overlap. The part of the baffle located under the protruding part fits snugly against the guide ledge. As a result, air from one temperature zone cannot penetrate into another temperature zone. If the guide lugs were provided on only two walls, then along the third wall, air or moisture from one temperature zone could enter another temperature zone, thereby affecting and changing the temperature, humidity, and odor in that zone.

Placing the baffle on the guide ledges allows, if necessary, to remove it for the most efficient use of space in the device case. There may be several such guides inside one housing. In this case, several partitions can be placed inside the device at the same time.

The claimed device expands the arsenal of technical means for transporting goods, including food, including food and drinks, and other household goods.

The essence of the device is illustrated by drawings, where in Fig. 1 shows the body of the device without a lid and without partitions, containing a top wall 1, side walls 2, a bottom wall 3, supports 4 for placing boxes, guide projections 5 for placing a partition. In FIG. 2 shows the body of the device without a cover and with partitions, containing a top wall 1, side walls 2, a bottom wall 3, supports 4 for placing boxes, guide projections 5 for placing a partition, a partition 6 with protruding parts 7.

The device is used as follows: based on the quantity, size, shape and temperature of the goods to be transported, shelves or boxes are placed on the supports, and partitions are placed on the guide ledges. Fill the case with goods, distributing goods with different temperatures and humidity to different temperature zones. Close the box with a lid and fix the lid tightly on the body due to the thorn-groove mechanism. The device can then be placed in a vehicle or can be carried as a backpack if a webbing frame connected to the shoulder straps and backrest is used.

During testing, the device was found to be able to simultaneously transport hot food and frozen food, such as berries or ice cream. At the same time, for an hour in the device, the frozen berries did not have time to melt, and the temperature of the ice cream dropped by only 1.5 degrees C. It was also experimentally established that when a body of a certain size is made (height from 500 to 700 mm, depth from 250 to 400 mm, width from 300 to 500 mm) it does not deform when fully loaded and retains its integrity.
