    Description

    RELATED ART



    [0001] The invention relates to the field of thermal insulation, namely to thermo-insulating products, and can be used to create liners that use material that provides resistance to external temperature, as well as capable of providing an indicator that is acceptable for transporting wine and other products to ensure thermal stability inside the liner in summer and winter.

    BACKGROUND OF THE INVENTION



    [0002] Perishable products are transported by road, sea, rail, and air transport using different technologies. When transporting expensive perishable goods, a controlled atmosphere, which is most suitable for the freshness retention, is usually used. By The controlled atmosphere refers to the creation, purification, and the like of a sealed or controlled atmosphere around products and usually includes the regulation of the content of at least one of the gases: nitrogen, oxygen, carbon dioxide, and ethylene.

    [0003] A device for storing biological objects in vacuum and at low temperatures is known; see RF patent No. 2132522, F 25 D 3/00, in 1999. The device contains two concentrically mounted cups of a vacuum-tight material, and vacuum-powder thermal insulation is placed between them. The gap between the cups is closed from the top with a spacer ring provided with a check valve. The cover of the device has a connection pipe for connecting a vacuum. In the pipe is installed a check valve. The check valve is installed in the pipe.

    [0004] A thermo-insulating product, which contains an insulating material, and its components are hermetically connected, is closest to the claimed invention on the technical essence, purpose, and the achieved result chosen as the prototype. The product also includes a covering foil, which is evacuated and hermetically welded [RF patent No. 2156914, IPC: F16L 59/06, F16L 59/02, BI No. 27, in 2000].

    [0005] The disadvantage of the product is a relatively high coefficient of thermal conductivity. In addition, during operation, it is impossible to periodically monitor its value.

    [0006] A lining bag for containers is known from CN205381588U. This lining bag has connectors as hooks and support members as magnets arranged on the top side of the lining bag. The lining bag is made of layered material comprising of four layers: outer emission layer of aluminium foil, enhancement layer of nylon, intermediate layer of plastic bubble film and internal reflective layer of aluminium foil. This lining bag does not provide UV protection of the cargo.

    [0007] A heat-insulated dampproof lining bag for container is known from CN202880199U. The lining bag comprises a bag body, a connection structure and a support structure. The bag body comprises at least four layers, wherein an inner layer and an outer layer are made of heat-reflecting materials - aluminium foil, a middle layer comprises a fabric layer that is fabric cloth and at least one layer of a plastic film with dampproof effect being PE or nylon. This lining bag does not provide UV protection of the cargo.

    SUMMARY IF THE INVENTION



    [0008] The basis of the invention is the object of reducing the thermal conductivity of the product.

    [0009] The problem is solved by the thermal liner according to claim 1. The thermal liner contains a thermal insulating material, and its components are hermetically connected. In accordance with the invention, the liner is configured to repeat the inner shapes of a metal container; it has a front wall that is openable, and its fastening elements are made along the upper perimeter with the possibility of fixing the liner in the container using a mounting cord and the inner lugs of the metal container. The thermal liner is made of a set of materials, and laminated metallized polyethylene foam (PE foam) with light-reflecting and heat-shielding ability as the thermal insulating material and a black polyethylene film with the possibility of avoiding ultraviolet rays through the liner are used.

    [0010] In accordance with another form of the invention, the thickness of the polyethylene foam ranges from 2 mm to 10 mm.

    [0011] In accordance with another form of the invention, eyelets are used as fastening elements.

    [0012] In accordance with another form of the invention, the polyethylene foam can have unilateral and bilateral lamination.

    [0013] In accordance with another form of the invention, the lamination is made of metallized film or covered with a thin layer of aluminium.

    [0014] In accordance with another embodiment of the invention, the bottom of the liner on the inside can be protected from damage during loading with an additional layer of woven polypropylene.

    [0015] In accordance with another embodiment of the invention, hinges, ties, or hooks are used as fastening elements of the liner inside the metal container.

    [0016] In accordance with another embodiment of the invention, the appliance cord is made in the form of tape, twine.

    [0017] In accordance with another embodiment of the invention, the liner component parts are heat sealed together.

    [0018] In accordance with another embodiment of the invention, the front wall can be opened with a zipper, as well as with a hook-and-loop fastener or polymer fastener.

    [0019] The invention achieves the task of reducing the thermal conductivity of the product due to the fact that the liner repeats the inner shapes of the container; it has a front wall that opens, and the eyelets are made along the upper perimeter with the possibility of fixing the liner in the container using a mounting cord and the inner lugs of the metal container. At that, the thermal liner is made of a set of materials, and laminated metallized polyethylene foam (PE foam) with light-reflecting and heat-shielding ability as the thermal insulating material and a black polyethylene film to ensure that the cargo in a metal container does not respond to ultraviolet radiation, sunlight, so that it is isolated from the penetration of cold or hot air, and does not subjected to sudden temperature changes that occur during container transportation across different continents, as well as temperature differences day/night, are used.

    [0020] After conducting tests with different materials in a thermal chamber, a complex of materials was developed that provide acceptable indicators of temperature differential, the difference of which is at least 9 degrees and above.

    [0021] Due to the fact that the liner material should be provided with a light-reflecting layer, an air barrier occurs that will not allow the external temperature to penetrate with the primary indicators inside the liner, as well as a layer that does not transmit UV rays.

    BRIEF DESCRIPTION OF THE DRAWINGS



    [0022] The invention is illustrated by drawings as follows:

    Fig. 1 shows a general view of the liner

    Fig. 2-the composition of the liner material.


    DETAILED DESCRIPTION OF THE INVENTION



    [0023] The liner 1 repeats the inner shapes of the container 2; it has a front wall that opens 3, and the eyelets 4 are made along the upper perimeter with the possibility of fixing the liner in the container using a mounting cord 5 and the inner lugs 6 of the metal container. At that, the thermal liner is made of a set of materials, and laminated metallized polyethylene foam (PE foam) 7 with light-reflecting and heat-shielding ability 8 as the thermal insulating material and a black polyethylene film 9 to ensure that the cargo in a metal container does not respond to ultraviolet radiation, sunlight, so that it is isolated from the penetration of cold or hot air, and does not subjected to sudden temperature changes that occur during container transportation across different continents, as well as temperature differences day/night, are used.

    [0024] The thermal liner is used in this way. In order to install the liner, you must unfold the liner and fix the upper part of the side walls with angular cords (tapes, twine) at the lugs (loops) of the container. After that, it is necessary to fix the lower part of the side walls of the liner with the help of angular and longitudinal cords (tapes, twine) in the lugs (loops) of the container. After fixing the angular and longitudinal tapes, you must insert the mounting cords (tapes, twine) into the lugs (loops) of the container and the grommet of the liner and fix them on the last lug (loop) of the container.

    [0025] Thermal insulation is achieved in this way. The metallized film with a reflective effect (a film deposited with aluminium or light-reflecting paint, or by using a thin layer of aluminium) is a light-reflecting layer.

    [0026] Polyethylene foam serves as an air barrier with a heat-shielding function, slowing down the action of sudden heating or cooling the temperature inside the container.

    [0027] The black plastic film serves as UV protection. One of its properties is also thermostability.

    [0028] The outer layer of the liner is made of polyethylene foam, laminated on one side with a reflective PET film, and a black opaque film is used as the inner layer.

    [0029] In order to prevent the penetration of air and the formation of condensate inside the liner during transportation, the thermal liner is produced by heat sealing of the material.

    [0030] Thus, the invention provides the composition of the material for the thermal liner, which provides the desired temperature difference between the external and internal temperatures and reduces the thermal conductivity of the product.
