Description

  The present invention relates to a container including a transport container and a cold and warm container stored in the transport container, and a cool and warm container used by being stored in the transport container.

  In recent years, global warming has become a serious problem. Along with this, energy saving is being promoted in the logistics field such as airplanes, railways, and trucks as well as other fields. Therefore, in containers used in the physical distribution field, weight reduction to reduce the weight and space saving to expand the internal space are extremely important issues.

  However, in the physical distribution field, it may be required to transport fresh products while maintaining freshness. In such a case, a transport container in which a cold insulated container is housed is used as a container.

  In general, a cold insulated container has a panel having a heat insulating member, thereby suppressing the movement of heat inside and outside the container. A conventional heat insulation container panel uses a foam heat insulating material as a heat insulating member. Recently, a cold insulation container using a vacuum heat insulating material for a panel has been proposed. Since the heat insulating performance per unit thickness of the vacuum heat insulating material is significantly higher than that of the foam heat insulating material, it is possible to reduce the weight and space of the cold insulating container while ensuring a desired cold insulating function.

  Patent Document 1 describes a housing panel that forms a rectangular parallelepiped sealed container in combination with a front panel and a top panel, and a vacuum heat insulating material is provided inside the housing panel.

  In Patent Document 2 and Patent Document 3, a cylindrical wall body having four wall surfaces having a vacuum heat insulating material, a lid body fitted to one edge portion of the wall body, and the other edge portion of the wall body. And a base that fits into the wall, the wall, the lid, and the base are separable from each other. Furthermore, Patent Document 2 and Patent Document 3 describe that a pair of opposing wall surfaces of the wall body can be folded into valley folds.

  By the way, the thing of patent document 1 thru | or patent document 3 is not all suitable for using with a container. In other words, when transporting cargo that does not require internal temperature control, if the cold insulated container is stored in the transport container in an assembled state, it may interfere with loading and unloading of cargo and hinder loading efficiency. There is a risk. Therefore, it is important that the cold and warm container used in the container can be assembled and folded as necessary. As a result, when transporting cargo that requires internal temperature control, the cool insulation container is stored in the transport container in an assembled state. On the other hand, when transporting cargo that does not require internal temperature control, The heat insulating container can be stored in the transport container in a folded state.

  Furthermore, since the cost reduction is important for the cold and warm container used in the container, it is important that the workability is good and a large work space is not required when performing assembly work and folding work. For example, it can be said that it is easy if a small number of people, such as two people, can perform most of the assembly work and folding work in the transport container. However, conventional cold insulated containers are not considered for enabling assembly and folding and for facilitating these operations for the purpose of use in containers.

  In Patent Document 1, the housing panel is composed of a rear panel part, a right side panel part, a left side panel part, and a bottom panel part, but the connection parts of these panel parts maintain airtightness. It is welded to. For this reason, it is impossible to fold the casing panel, and there is a problem that a considerably large storage space is required even when not in use.

  Moreover, in patent document 2 and patent document 3, there is no specific description regarding the dimension of a box body, and opening / closing is limited to a top | upper surface in the state which stood the wall body on structure. In order to expand the folded wall body into a cylindrical shape, it is necessary for the operator to enter the inside of the wall body and push the wall wall that has been folded into the valley to the outside. When the size of the wall is increased, it is difficult for an operator to enter the inside of the wall because the opening and closing is limited to the top surface when the wall is standing. In addition, the worker can enter the inside of the wall body while the wall body is laid down, but the work of standing the wall body expanded in a cylindrical shape requires an excessive amount of labor, and the surrounding area is sufficient. There is a problem that a work space is required. Further, in the folding work, it is necessary to disassemble the cover body, the base, and the wall body, and the number of parts is large and the workability is poor. Further, in the assembly work, it is necessary to appropriately position the lid and the base separated from the wall body with respect to the wall body without mistakes in the direction and the front and back, and the burden on the operator is great. Moreover, since it can be decomposed | disassembled into a cover body, a base, and a wall body, there also exists a problem that heat enters / exits easily between a cover body and a wall body and between a wall body and a base.

  The present invention has been made in consideration of the above points. An object of the present invention is to provide a cold and warm container that can easily perform an assembling operation and a folding operation and can maintain an internal temperature well, and a container including the same.

  The present invention is a container comprising a transport container and a cold and warm container stored in the transport container, wherein the cool and warm container is a top panel, a front panel that can be opened and closed, a left panel, and a rear panel. , And a side panel and a bottom panel, which are connected to each other via a connecting part so as to be bendable, and the top panel, the side panel, and the bottom panel are bent together via the connecting part. It is connected so as to form a flat connection panel at the time of deployment, the cold insulation container can be assembled in the transport container, and the top panel, the side panel, and the bottom panel have heat insulating members. It is a featured container.

  Further, the present invention is a cold insulation container that is used by being housed in a transport container of a container, wherein the top panel, the front panel that can be opened and closed, the left panel, the back panel, and the right panel via the connecting portion. The side panel and the bottom panel are connected to each other in a foldable manner, and the top panel, the side panel, and the bottom panel are connected to each other via a connecting portion so as to be foldable, and are flat when deployed. The top panel, the side panel, and the bottom panel have a heat insulating member.

  In the present embodiment, the bottom panel 16 has a pair of heat insulating members 20B for the bottom with an outer bag corresponding to the pair of partial panels 16a and 16b.

  The exterior bag 25 of the bottom surface heat insulating member 20B with the exterior bag is the same as the exterior bag 25 of the above-described heat insulating member 20A with the exterior bag, and the description thereof is omitted.

  On the other hand, the bottom heat insulating member 20 ′ includes a foam heat insulating material 26 and a bottom surface protective material 27 laminated on the foam heat insulating material 26.

  Next, constituent materials of each part will be described.

(Insulating member 20)
First, the material of the heat insulating member 20 will be described. As described above, the heat insulating member 20 includes the vacuum heat insulating material 21, the pair of additional heat insulating materials 22, and the protective material 23.

  Among these, the vacuum heat insulating material 21 consists of the core material 21a and the gas barrier outer covering material 21b covering the core material 21a.

  Further, as the additional heat insulating material 22, a general foam material can be used. Specifically, foamed plastic heat insulating materials such as extruded foamed polystyrene, beaded polystyrene, urethane foam, highly foamed polyethylene, and phenol foam can be used.

  Further, the protective material 23 is as follows. In other words, the vacuum heat insulating material 21 is prone to cracks, wrinkles and penetration due to external damage, etc., and when used alone, it is particularly easy to damage during the physical distribution process. Once the exterior is destroyed, the degree of vacuum is lowered and sufficient heat insulation is maintained. It may not be possible. Therefore, in the present embodiment, the front and back surfaces of the vacuum heat insulating material 21 are covered with the additional heat insulating material 22, and the vacuum heat insulating material 21 is protected by covering the outside of the container of the additional heat insulating material 22 with the protective material 23. The material 21 can be used repeatedly.

  The protective material 23 is not particularly limited as long as it has rigidity with a protective function. For example, a plywood, a steel plate, a foamed material, a rigid resin plate, an embossed resin sheet, a paperboard or the like may be used. In particular, since the transportation cost can be reduced by reducing the volume, it is particularly preferable in terms of cost and weight to use a so-called curing material, Pradan (plastic cardboard), or a composite material thereof.

The thermal conductivity of the material forming the heat insulating member 20 is not particularly limited as long as the desired heat insulating property can be exhibited. For example, it is 100 mW · m ⁻¹ · K ⁻¹ or less, especially 50 mW · m ⁻¹ · It is preferably K ⁻¹ or less, particularly 35 mW · m ⁻¹ · K ⁻¹ or less. This is because if the thermal conductivity of the heat insulating member 20 is large, it is difficult to exhibit a sufficient heat insulating function.

In addition, the specific heat of the material constituting the heat insulating member 20 is not particularly limited as long as desired heat insulating properties can be exhibited. For example, 0.5 kJ · g ⁻¹ · K ^{−1 to} 2.0 kJ · g ^−1. · ^K is about ^-1, inter alia ^{0.8kJ · g -1 · K -1 ~1.5kJ} · g -1 · K in the range of ^-1, particularly 1.0 kJ ^{· g} -1 · ^{K -1} ~ It is preferable to be within the range of 1.4 kJ · g ⁻¹ · K ⁻¹ .

  The thickness of the heat insulating member 20 is not particularly limited as long as it can have a desired heat insulating property, and can be appropriately selected according to various applications. Preferably, for example, it is preferably within a range of 0.1 mm to 100 mm, more preferably within a range of 1 mm to 80 mm, and particularly preferably within a range of 3 mm to 50 mm.

  When the thickness of the heat insulating member 20 is too thick, the heat insulating member 20 becomes heavy, the whole cold insulation container 10 becomes heavy, and the handling of the cold insulation container 10 may be difficult. On the other hand, if the heat insulating member 20 is too thin, it may be difficult to exhibit sufficient heat insulating properties, or the vacuum heat insulating material 21 of the heat insulating member 20 may be easily damaged. Moreover, in this Embodiment, it is more preferable that the thickness of the heat insulation member 20 is thin within the numerical range mentioned above.

  In the cold insulation container 10 according to the present embodiment, if the thickness of the protective material 23 is reduced, not only can it be quantified, but the heat insulation function of the vacuum insulation material 21 can be further exerted. The size can be suppressed. Moreover, the thickness as the heat insulation member 20 whole can be made thin, and weight reduction and compactization can be shown. In this case, since the cold insulated container 10 according to the present embodiment can be made light, the burden on the operator in the assembling work and the disassembling work can be reduced.

(Exterior bag 25)
Next, the material of the exterior bag 25 will be described.

  The outer bag 25 is made of a soft flexible material having heat insulation properties, and a bag made of PET, aluminum foil, polyethylene foam, or the like, or PET, aluminum foil, pef, or the like can be used. By using a soft bag as the outer bag 25, it is possible to prevent scratches and the like of the stored heat insulating member 20, and to extend the product life.

(Insulating member 20 ′ for bottom surface)
Next, the material of the bottom surface heat insulating member 20 ′ will be described. The bottom heat insulating member 20 ′ has the foam heat insulating material 26 and the bottom surface protective material 27 laminated on the foam heat insulating material 26 as described above.

  As the foam heat insulating material 26, as with the additional heat insulating material 22, a general foam material can be used. Specifically, examples thereof include foamed plastic heat insulating materials such as extruded foamed polystyrene, beaded polystyrene, urethane foam, highly foamed polyethylene, and phenol foam.

  As with the protective material 23, the bottom surface protective material 27 is not particularly limited as long as it has rigidity having a protective function. For example, a plywood, a steel plate, a foamed material, a rigid resin plate, an embossed resin sheet, a paperboard or the like is used. However, since the transportation cost can be reduced by reducing the weight and volume in terms of physical distribution, it is particularly preferable to use a so-called curing material, prada (plastic corrugated cardboard), or a composite material thereof, particularly in terms of cost and weight. preferable.

  Next, with reference to FIG. 9A to FIG. 9E, the operation of the present embodiment configured as described above will be described.

  First, as shown in FIG. 9 (a), the cold insulated container 10 in a state of being folded through the connecting portions 31a to 31e is, for example, in an aluminum transport container 2 (see FIG. 1b) of an air transport container. It is carried in. In the present embodiment, the top panel 11 and the side panels 12, 13, 14, and 15 are lightweight because they include a vacuum heat insulating material, and even if the length in the total height direction is 1 m or more, one person Or it can be easily carried in by a small number of workers.

  Next, in the transport container 2, as shown in FIG. 9 (b), the right panel 15 is expanded via the connecting portion 31c, and one partial panel 12b of the front panel 12 is connected via the connecting portion 31d. Can be spread.
