FIG. 1 is a perspective view showing a cold insulation container 10 according to an embodiment of the present invention. FIG. 2 is a perspective view showing a state in which the openable and closable front panel 12 is opened in the cold and warm container 10 of FIG. FIG. 3 is a perspective view showing a state where one partial panel 11a of the top panel 11 is opened in the cold insulation container 10 of FIG. FIG. 4 is an internal plan view of the cold insulation container 10 of FIG. 1 in which the top panel 11 is not shown. FIG. 10 is a perspective view showing a cold and warm container composite 1 according to an embodiment of the present invention, in which two or more (two in the illustrated example) of the cold and warm containers 10 of FIG. 1 are stacked.

As shown in FIGS. 1 to 4, the cold insulation container 10 according to the present embodiment includes a top panel 11, a front panel 12, a left panel 13, a back panel 14, and a side panel 12 having a

right panel

15, 13, 14, 15 and a bottom panel 16, and stores articles to be kept cold or warm inside. As shown in FIG. 10, two or more cold-insulated containers 10 having such a configuration are stacked and placed on a cart (not shown) (also referred to as a roll box pallet), for example, as shown in FIG. Then, it is transported by a cage car in a stacked state.

The structure of the cold insulation container 10 will be described. The

side panels

12, 13, 14, and 15 of the cold insulation container 10 have a heat insulating member 20 including a vacuum heat insulating material 21 as described later. By using the vacuum heat insulating material 21 for the

side panels

12, 13, 14, and 15, the panel itself is made thinner and lighter while achieving high heat insulation. Moreover, the weight reduction of the

side panels

12, 13, 14, 15 can be achieved, so that two or more cold insulation containers 10 can be easily stacked.

In the present embodiment, a reinforcing body 31 extending in the entire height direction of the front panel 12 and the right panel 15 is provided between the

adjacent side panels

12, 13, 14, 15, for example, between the front panel 12 and the right panel 15. Is provided. The reinforcing body 31 is made of a rigid material and has higher load resistance (compressive strength) than each of the

side panels

12, 13, 14, 15.

Adjacent side panels

12, 13, 14, 15 are connected to each other via a reinforcing body 31.

Further, each

side panel

12, 13, 14, 15 and the reinforcing body 31 are supported with their end surfaces being in contact with the upper surface of the bottom panel 16. On the other hand, the top panel 11 is supported by the peripheral edge of the bottom surface being in contact with the

side panels

12, 13, 14, 15 and the end surfaces of the reinforcing bodies 31.

Thus, the four reinforcing bodies 31 are erected so as to be spanned between the top panel 11 and the bottom panel 16, thereby acting between the top panel 11 and the bottom panel 16. The compressive load is supported by the reinforcing body 31, and unless the reinforcing body 31 is deformed, a large load is not applied to the

side panels

12, 13, 14, and 15. Thereby, sufficient load resistance is ensured, without increasing the thickness of the

side panels

12, 13, 14, and 15.

As shown in FIGS. 2 and 3, in the cold and warm container 10, both the front panel 12 and the top panel 11 can be opened and closed.

In the present embodiment, the openable front panel 12 has a pair of

partial panels

12a and 12b. The pair of

partial panels

12a and 12b of the front panel 12 are connected to the adjacent left side panel 13 and right side panel 15 via a reinforcing body 31, respectively, and are connected to the outside of the reinforcing body 31 via folding lines extending in the entire height direction. Can be bent. Thereby, a pair of

partial panel

12a, 12b of the front panel 12 comprises the double door of the cold insulation container 10. Since the pair of

partial panels

12a and 12b of the front panel 12 constitute a double door, the space in the front-rear direction (depth direction) required when the front panel 12 is opened can be reduced. Although not shown, the front panel 12 may be provided with a reinforcing member that covers the folding line on the outer surface side to increase the strength. Alternatively, from the viewpoint of further increasing the strength, the front panel 12 may be connected to the outside of the reinforcing body 31 so as to be openable and closable via a hinge.

In the illustrated example, a flap 51 with a male surface fastener is provided on the outer surface of the side edge of one partial panel 12b of the front panel 12, and on the outer surface of the side edge of the other partial panel 12a. A female surface fastener (not shown) that can contact the flap 51 with the male surface fastener is provided. In the present specification, “inner surface” means a surface facing the inside of the cold insulated container 10, and “outer surface” means a surface facing the outer side of the insulated container 10. As shown in FIG. 1, when the pair of

partial panels

12a and 12b of the front panel 12 are closed, the flap 51 with the male surface fastener is brought into contact with the female surface fastener, thereby the pair of partial panels 12a. , 12b are closed and locked. Instead of the hook-and-loop fastener, a fastener, a double door lock, a stopper, or the like can be used.

In the present embodiment, the openable and closable top panel 11 has a pair of

partial panels

11a and 11b that can be folded via a fold line 33. As shown in FIG. 3, the folding line 33 extends in the full width direction (left-right direction) parallel to the front panel 12 in the vicinity of the center of the top panel 11 in the front-rear direction (depth direction). While one partial panel 11b of the top panel 11 is in contact with and supported by the end surfaces of the left panel 13, the back panel 14, and the right panel 15, the other partial panel 11a is folded via the fold line 33. As a result, the other partial panel 11a is opened.

As described above, since both the front panel 12 and the top panel 11 can be opened and closed, articles can be easily put in and out regardless of the height position of the place where the cold and warm container 10 is installed. Specifically, for example, when the cold and warm container 10 is installed at a relatively high position with respect to the worker, by opening the front panel 12, the worker can remove the article without using a stepladder or a step ladder. Easy to put in and out. On the other hand, for example, when the cold and warm container 10 is installed at a relatively low position with respect to the worker, by opening the top panel 11, the worker can easily put in and out articles without squatting. .

In addition, since the front panel 12 can be opened and closed, articles can be taken into and out of any container while two or more cold and warm containers 10 are stacked.

As shown in FIGS. 2 and 3, in the present embodiment, pocket shapes for storing a cold insulation material or a thermal insulation material on the inner surfaces of the top panel 11, the left panel 13, the back panel 14, and the right panel 15, respectively. The storage part 41 is provided. Such pocket-shaped storage portions 41 are not necessarily provided on the inner surfaces of the top panel 11, the left panel 13, the back panel 14, and the right panel 15, for example, on the inner surface of the front panel 12 or the bottom panel 16. It may be provided.

As shown in FIG. 11, in the present embodiment, the top panel 11, the

side panels

12, 13, 14, 15 and the bottom panel 16 can be separated from each other. Further, the front panel 12, the left panel 13, the back panel 14, and the right panel 15 of the

side panels

12, 13, 14, and 15 can be separated from each other. Note that “separable to each other” means that adjacently connected panels can be separated. For example, “The top panel, side panel, and bottom panel are separable from each other” means that the top panel and side panel are connected side by side, and the side panel and bottom panel are connected side by side. In this case, the top panel and the side panel are separable from each other, and the side panel and the bottom panel are separable from each other. In addition, in FIG. 11 thru | or FIG. 13 demonstrated below, illustration of the reinforcement body 31 and the accommodating part 41 is abbreviate | omitted.

When each

panel

11, 12, 13, 14, 15, 16 of the cold insulation container 10 is separable, when the panel including the vacuum heat insulating material 21 is damaged, only the damaged panel is replaced. Can be repaired easily. Hereinafter, the separated set of

panels

11, 12, 13, 14, 15, 16 of the cold insulation container 10 is also referred to as “assembled type cold insulation container panel set”.

In the present embodiment, as shown in FIG. 12, in the assembly-type cold insulation container panel set, the

side panels

12, 13, 14, and 15 are stacked between the top panel 11 and the bottom panel 16. It can be stored. Thereby, during storage of the panel set, the

side panels

12, 13, 14, and 15 are protected by the top panel 11 and the bottom panel 16, and the vacuum heat insulating material 21 included in the

side panels

12, 13, 14, and 15 is damaged. Is prevented.

[Correction based on Rule 91 17.06.2015]
In the illustrated example, a fixture 60 that temporarily fixes the top panel 11 and the bottom panel 16 is provided. As the fixture 60, for example, a binding band, a fastener, a hook-and-loop fastener, or the like is used. The top panel 11 and the bottom panel 16 are temporarily fixed by the fixture 60, so that the

side panels

12, 13, 14, and 15 are securely secured by the top panel 11 and the bottom panel 16 during storage of the panel set. Can be protected. Further, the top panel 11 and the bottom panel 16 are temporarily fixed by the fixture 60, so that each

panel

11, 12, 13, 14, 15, 16 is integrated, and the thickness of the entire panel set 10 is reduced. Therefore, the panel set 10 can be stored in an upright state.

In the cold and warm container 10 of the present embodiment, it is preferable to attach distinguishable marks to the top panel 11, the bottom panel 16, and the

side panels

12, 13, 14, and 15, respectively. As the mark, letters, numbers, symbols, colors, and the like can be used. For example, the name of “XX panel”, serial numbers such as 1, 2, 3, etc., different symbols such as XX may be displayed on the surface of the panel, or the color of the surface of the panel may be changed. Thereby, the work efficiency of the worker who performs the assembly work is improved. Further, the disassembled cold and warm insulation container can be stored in such a state and order that it is easy to assemble. Further, when the

side panels

12, 13, 14, and 15 can be separated through the separation unit, the top panel 11, the bottom panel 16, and the separated

side panels

12, 13, 14, and 15 are respectively separated. It is more preferable to attach a distinguishable mark. When the

side panels

12, 13, 14, and 15 are separable via the separating portion, the number of parts increases during assembly, and the shape of each part is similar, so that the operator is more likely to get lost. It is.

Next, the structure of the

side panels

12, 13, 14, 15 will be described in detail.

FIG. 5 is an enlarged cross-sectional view showing a portion surrounded by a one-dot chain line denoted by reference symbol A in the cold insulation container 10 of FIG. FIG. 6 is an enlarged cross-sectional view of a portion surrounded by an alternate long and short dash line with a symbol B in the cold and warm container 10 of FIG.

As shown in FIG. 5 and FIG. 6, in this embodiment, each of the

side panels

12, 13, 14, 15 has a heat insulating member 20 including a vacuum heat insulating material 21. However, if the desired cold insulation function can be ensured, it is not always necessary that all of the

side panels

12, 13, 14, and 15 have the heat insulating member 20 including the vacuum heat insulating material 21. It is sufficient that at least one of 12, 13, 14, and 15 has the heat insulating member 20 including the vacuum heat insulating material 21. For example, the left panel 13, the back panel 14, and the right panel 15 have a heat insulating member 20 including a vacuum heat insulating material 21, but the front panel 12 has a heat insulating property including the vacuum heat insulating material 21 in order to increase the strength. The aspect of not having the member 20 may be sufficient. Since the front panel 12 often comes into contact with people and luggage during opening and closing operations and loading and unloading operations, according to such an aspect, the risk of the vacuum heat insulating material 21 being damaged can be reduced. Or when connecting the front panel 12 through a hinge so that opening and closing is possible, it is necessary to fix a hinge to the front panel 12 using a screw, a nail, etc., and there exists a risk that the vacuum heat insulating material 21 will be damaged by this screw or nail. Therefore, it can be considered not to provide the vacuum heat insulating material 21 on the front panel 12.

As shown in FIGS. 5 and 6, the heat insulating member 20 includes at least a vacuum heat insulating material 21, an additional heat insulating material 22 stacked on the inner surface of the vacuum heat insulating material 21, and a protection stacked on the outer surface of the vacuum heat insulating material 21. And a material 23. Moreover, between the additional heat insulating material 22 and the protective material 23, the peripheral part foam heat insulating material 221 is filled so that the peripheral part of the vacuum heat insulating material 21 may be enclosed.

9A and 9B are cross-sectional views showing the vacuum heat insulating material 21. FIG.

As shown in FIGS. 9A and 9B, the vacuum heat insulating material 21 includes a core material 21a made of any one of a fiber material, a resin foam material, and a granular material, and covers the core material 21a and has a gas barrier property. A heat insulating material obtained by reducing the pressure inside the jacket material 21b to a vacuum state. In this case, as shown in FIG. 9A, spaces are formed at both ends of the core material 21a in the jacket material 21b. However, as shown in FIG. 9B, spaces are formed at both ends of the core material 21a in the jacket material 21b. The outer covering material 21b may be brought into close contact without forming.

5 and 6, a general foam material can be used as the additional heat insulating material 22 and the peripheral portion foam heat insulating material 221. Specifically, foamed plastic heat insulating materials such as extruded foamed polystyrene, beaded polystyrene, urethane foam, highly foamed polyethylene, and phenol foam can be used.

Moreover, 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 this embodiment, the additional heat insulating material 22 and the peripheral edge foamed heat insulating material 221 cover the inner surface and the peripheral edge of the vacuum heat insulating material 21, and the protective material 23 covers the outer surface of the vacuum heat insulating material 21. The heat insulating material 21 is protected, and the vacuum heat insulating 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.

Further, the specific heat of the material constituting the heat insulating member 20 is not particularly limited as long as the desired heat insulating property can be exhibited. For example, 0.5 kJ · g ⁻¹ · K ⁻¹ to 2.0 kJ · g ⁻¹・ K- ¹ or so, in particular, within the range of 0.8 kJ · g ⁻¹ · K ⁻¹ to 1.5 kJ · g ⁻¹ · K ⁻¹ , especially 1.0 kJ · g ⁻¹ · K ⁻¹ It is preferably 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 has a desired heat insulating property and can be appropriately selected according to various applications. Preferably, for example, it is preferably in the range of 0.1 mm to 100 mm, more preferably in the range of 1 mm to 80 mm, and particularly preferably in the 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 become 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 the weight be reduced, but the heat insulation function of the vacuum insulation material 21 can be further exerted. Dimension 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, it is possible to reduce the burden on the operator in the work of stacking two or more.

In the present embodiment, as shown in FIGS. 5 and 6, the protective material 23 is formed such that each side is larger than each side of the additional heat insulating material 22, and both side edges and the upper end of the protective material 23 are These are extended so as to protrude from both side edge portions and upper end portions of the additional heat insulating material 22, respectively. On the other hand, the lower end portion of the protective material 23 is arranged at the same height as the lower end portion of the additional heat insulating material 22.

And the reinforcement body 31 extended in the full height direction of the protective material 23 is provided in the both-sides edge extended so that the protective material 23 might protrude. By doing in this way, the heat insulating member 20 can be fixed to the reinforcing body 31 without applying a load to the vacuum heat insulating material 21. That is, by providing the reinforcing body 31 in the portion of the heat insulating member 20 where the vacuum heat insulating material 21 does not exist, the tip of the reinforcing body 31 applies a strong pressure to the vacuum heat insulating material 21 when the heat insulating member 20 moves. It is possible to prevent the vacuum heat insulating material 21 from being damaged. Further, as described later, when the side edge portion of the heat insulating member 20 is inserted and fixed between the pair of leg portions of the reinforcing body 31, the pressure by the pair of leg portions of the reinforcing member 31 is increased by the heat insulating member 20. The vacuum heat insulating material 21 can be prevented from being applied.

In the present embodiment, as shown in FIGS. 5 and 6, the reinforcing body 31 corresponds to the male reinforcing body 31 a provided on the side edge of the left panel 13, and the adjacent front panel 12 and back panel 14. And a female reinforcement body 31b that engages with the male reinforcement body 31a provided on the side edge.

More specifically, as shown in FIG. 5 and FIG. 6, the male reinforcing body 31a has a protruding strip portion having a substantially square cross section and a pair of leg portions extending in a direction opposite to the protruding strip portion. ing. On the other hand, the female reinforcing member 31b includes a concave groove portion having a substantially square cross section that can engage with the convex portion of the male reinforcing member 31a, and a pair of leg portions extending in a direction of 90 ° with respect to the concave groove portion. ,have.

And the side edge part of the left surface panel 13 is crimped and fixed to the pair of leg parts while being inserted between the pair of leg parts of the male reinforcing body 31a. Although not shown, similarly, the side edge portion of the right panel 15 is also crimped and fixed to the pair of leg portions while being inserted between the pair of leg portions of the male reinforcing body 31a. .

On the other hand, the side edge portion of the front panel 12 is fixed by being crimped to the pair of leg portions while being inserted between the pair of leg portions of the female reinforcing body 31b. Similarly, the side edge part of the back surface panel 14 is crimped | fixed and fixed to the said pair of leg part in the state inserted between the pair of leg parts of the female-type reinforcement body 31b.

Then, as shown in FIG. 5, the protrusions of the male reinforcement 31 a fixed to the side edge of the left panel 13 are recessed grooves of the female reinforcement 31 b fixed to the side edge of the front panel 12. The left panel 13 is connected to the front panel 12 by being engaged. At this time, the male reinforcing member 31a and the female reinforcing member 31b function as a jig, so that the left panel 13 can be accurately and easily connected to the front panel 12 in a direction of 90 °.

Further, as shown in FIG. 6, the protrusions of the male reinforcement 31 a fixed to the side edge of the left panel 13 are recessed with the female reinforcement 31 b fixed to the side edge of the back panel 14. The left panel 13 is connected to the back panel 14 by being engaged with the groove. At this time, the male reinforcing body 31a and the female reinforcing body 31b function as a jig, so that the left panel 13 can be accurately and easily connected to the back panel 14 in a direction of 90 °.

Although not shown, similarly, the protruding strip portion of the male reinforcing body 31a fixed to the side edge portion of the right panel 15 is a concave groove portion of the female reinforcing body 31b fixed to the side edge portion of the front panel 12. As a result, the right panel 15 is connected to the front panel 12. At this time, the male reinforcing member 31a and the female reinforcing member 31b function as jigs, so that the right panel 15 can be accurately and easily connected to the front panel 12 in a direction of 90 °.

Further, the protrusions of the male reinforcement 31 a fixed to the side edge of the right panel 15 are engaged with the grooves of the female reinforcement 31 b fixed to the side edge of the back panel 14. Thus, the right panel 15 is connected to the back panel 14. At this time, the male reinforcing body 31a and the female reinforcing body 31b function as a jig, so that the right panel 15 can be accurately and easily connected to the back panel 14 in a direction of 90 °.

The material of the reinforcing body 31 is not particularly limited as long as it is a rigid material having a high load resistance, but is preferably lightweight, and for example, an organic material such as polypropylene is suitably used.

The size of the reinforcing body 31 is not particularly limited as long as it can have a desired load resistance, and can be appropriately selected according to various applications. Specifically, for example, a pair of male reinforcing bodies 31a The space | interval of a leg part is 7 mm, the length of each leg part is 33 mm, and the thickness is 3 mm. Further, the distance between the pair of leg portions of the female reinforcing body 31b is 7 mm, the length of each leg portion is 33 mm, and the thickness thereof is 3 mm. The load resistance of the reinforcing body 31 is 3 t, for example.

As shown in FIGS. 5 and 6, the reinforcing body 31 preferably has a substantially L-shaped cross section as a whole. In this case, not only the compressive strength in the vertical direction but also the strength against the external force in the horizontal direction can be improved.

In this embodiment, as shown in FIGS. 5 and 6, the corner foam heat insulating material 222 is laminated on the inner surface of each reinforcing body 31, and the four

side panels

12, 13, 14, 15 are connected to each other. In this case, the corner foam heat insulating material 222 covers the inner surfaces of the four corners of the cold insulation container 10. Thereby, the heat insulation of four corners of the cold insulation container 10 is further improved.

As the corner foam heat insulating material 222, a general foam material can be used as in the case of the additional heat insulating material 22 and the peripheral edge foam heat insulating material 221. 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, as shown in FIG. 5, a groove having a V-shaped cross section is formed in the inner surface of the protective member 23 of the front panel 12 corresponding to the side edge of the additional heat insulating material 22 so as to extend in the entire height direction. Has been. Accordingly, the pair of

partial panels

12a and 12b can be bent through the ridge line of the groove while being connected to the adjacent left panel 13 and right panel 15 via the rigid reinforcement body 31.

Next, the structure of the top panel 11 will be described in detail.

FIG. 7 is a cross-sectional view of one end portion of the top panel 11. As shown in FIG. 7, the top panel 11 includes a top panel main body 111 including the vacuum heat insulating material 21 and a heat insulating protrusion 112 provided on the periphery of the top panel main body 111. However, the structure of the top panel 11 is not limited to this, and the top panel 11 may be composed of only the top panel body 111.

The top panel body 111 includes at least a vacuum heat insulating material 21, a pair of additional heat insulating materials 22 that sandwich the vacuum heat insulating material 21 from both sides, and a protective material 23 laminated on the outer surface of one additional heat insulating material 22. Have. Further, between the pair of additional heat insulating materials 22, a peripheral portion foam heat insulating material 221 is filled so as to surround the peripheral portion of the vacuum heat insulating material 21.

The protective material 23 is formed so that the length of each side is larger than each side of the additional heat insulating material 22, and the outer edge portion of the protective material 23 is extended so as to protrude outward from the outer edge portion of the additional heat insulating material 22. ing. And as shown in FIG. 7, the bottom face of the outer edge part extended so that the protective material 23 may protrude is contact | abutted to the end surface of each

side panel

12, 13, 14, 15 and the reinforcement body 31, and is supported. It is like that.

The heat-insulating protrusion 112 is not particularly limited as long as it has a protective function, like the protective material 23. 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.

As shown in FIG. 7, when the bottom surface of the outer edge portion of the top panel body 111 is supported by being in contact with the end surfaces of the

side panels

12, 13, 14, 15 and the reinforcing body 31, the heat insulating protrusion 112 is The outer surfaces of the upper end portions of the

side panels

13, 14, 15 are covered. Thereby, the heat insulation of the upper end part of the

side panels

13, 14, 15 can be further improved.

Further, as shown in FIG. 1, a groove having a V-shaped cross section is formed on the inner surface of the protective member 23 of the top panel body 111 corresponding to the boundary between the pair of

partial panels

11a and 11b in the full width direction (front surface). The pair of

partial panels

11a and 11b can be bent via a ridge line of the groove. That is, the ridge line of the groove constitutes a fold line 33, and the pair of

partial panels

11 a and 11 b can be folded via the fold line 33. Since the pair of

partial panels

11a and 11b includes the vacuum heat insulating material 21, the pair of

partial panels

11a and 11b are lightweight and can be easily folded (that is, the top panel 11 is opened and closed).

Since the top panel 11 often comes in contact with people and luggage during opening and closing operations and loading / unloading operations, it may be possible not to use a vacuum heat insulating material for the heat insulating member of the top panel 11. Thereby, the risk that the vacuum heat insulating material 21 is broken and the heat insulating performance is significantly reduced can be reduced. Moreover, the side panel using the vacuum heat insulating material can be protected by the panel set.

Next, the structure of the bottom panel 16 will be described in detail.

FIG. 8 is a cross-sectional view of one end portion of the bottom panel 16. As shown in FIG. 8, the bottom panel 16 includes at least a vacuum heat insulating material 21 and a pair of additional heat insulating materials 22 that sandwich the vacuum heat insulating material 21 from both surfaces. Further, between the pair of additional heat insulating materials 22, a peripheral portion foam heat insulating material 221 is filled so as to surround the peripheral portion of the vacuum heat insulating material 21.

As shown in FIG. 8, the

side panels

12, 13, 14, and 15 are supported by their end surfaces being in contact with the upper surface of the outer edge portion of the bottom panel 16. Here, the vacuum heat insulating material 21 of the bottom panel 16 is the inner surface of the

side panels

12, 13, 14, 15 so that the load of the

side panels

12, 13, 14, 15 is not directly applied to the vacuum heat insulating material 21 of the bottom panel 16. It is arranged further inside.

In addition, since the bottom panel 16 directly contacts when putting a load or is rubbed by vibration when moving the container, it may be considered not to use a vacuum heat insulating material for the heat insulating member of the bottom panel 16. It is done. Thereby, the risk that the vacuum heat insulating material 21 is broken and the heat insulating performance is significantly reduced can be reduced. Moreover, the side panel using the vacuum heat insulating material can be protected by the panel set.

In the present embodiment, as shown in FIG. 8, a handle portion 29 is attached to the bottom surface of the bottom panel 16. The handle portion 29 is made of, for example, a string-like member, and extends upward from the bottom surface of the bottom panel 16 along the outer surfaces of the left panel 13 and the right panel 15 (see FIG. 1). By grasping and lifting the handle portion 29, the entire cold insulated container 10 can be lifted without applying a load to the

side panels

12, 13, 14, 15.

Next, the operation of the present embodiment configured as described above will be described.

First, when the cold insulation container 10 is installed at a relatively high position with respect to the worker, as shown in FIG. 2, the pair of

partial panels

12a and 12b of the front panel 12 are opened, and this partial panel 12a is opened. , 12b, the article is stored inside the cold insulation container 10. Then, after the article is stored in the cold insulation container 10, the pair of

partial panels

12a and 12b of the front panel 12 are closed. At this time, the flap 51 with the male surface fastener provided at the side edge of the other partial panel 12b is brought into contact with the female surface fastener provided at the side edge of the one partial panel 12a. The pair of

partial panels

12a and 12b are locked while closed.

On the other hand, when the cold insulation container 10 is installed at a relatively low position with respect to the operator, one partial panel 11a of the top panel 11 is folded via the folding line 33 as shown in FIG. Then, the article is opened, and the article is stored from the partial panel 11 a into the cold insulation container 10. Then, after the article is stored in the cold insulation container 10, one partial panel 11 a of the top panel 11 is returned through the fold line 33 and closed.

Next, the cold insulation container 10 in which the articles are stored is grasped and lifted by the handle portion 29, and, as shown in FIG.

At this time, since the vacuum heat insulating material 21 is used for the

side panels

12, 13, 14, and 15 of the cold insulation container 10, the weight reduction is achieved, so that two or more cold insulation containers 10 can be easily stacked. . Moreover, the load concerning each

side panel

12, 13, 14, 15 is reduced by grasping the handle part 29 fixed to the bottom panel 16 and lifting the cold insulation container 10.

Further, in the present embodiment, the load of the upper cold insulation container 10 is supported by the reinforcing bodies 31 at the four corners of the lower cold insulation container 10, and the

side panels

12, 13, 14, 15 is further reduced.

After that, two or more of the cold and warm containers 10 are transported to the next process by a basket car while being stacked. Then, in the next step, as shown in FIG. 10, the front panel 12 is opened and articles are taken in and out from the front panel 12 while two or more cold insulation containers 10 are stacked. By opening the front panel 12 in this way, it is possible to put in and out the article with respect to the lower cold insulation container 10 while two or more are stacked. Note that the top panel 11 may be opened for the upper cold insulation container 10.

Since articles can be taken in and out in any container while two or more cold insulation containers 10 are stacked, for example, the insulation containers 10 having different management temperatures (for example, refrigeration controlled at a temperature of 0 ° C. to 10 ° C.) Two or more refrigeration containers and refrigeration containers controlled at a temperature of −15 ° C. or lower), and an article can be taken in and out while sorting.

Next, the process of separating the cold and warm container 10 into each panel when not in use will be described.

First, two or more of the cold insulation containers 10 stacked are grasped by the handle 29 in order from the upper insulation container 10 in the state where each interior is emptied and lowered from the cart.

Next, in each cold insulation container 10, the top panel 11 is lifted from the end surfaces of the

side panels

12, 13, 14, 15 and separated.

Next, the

adjacent side panels

12, 13, 14, 15 are separated from each other via the reinforcing body 31. More specifically, for example, the left panel 13 is lifted upward. At this time, as shown in FIG. 5 and FIG. 6, the protrusions of the male reinforcing body 31 a fixed to the side edge of the left panel 13 are the side edges of the front panel 12 and the back panel 14 adjacent thereto. It is guided by the concave groove part of the female reinforcement 31b fixed to the part and translated upward. Then, when the lower end portion of the protruding portion of the male reinforcing member 31a is lifted upward from the upper end portion of the recessed groove portion of the female reinforcing member 31b, the male reinforcing member 31a and the female reinforcing member 31b are engaged. Is eliminated, and the left panel 13 is separated from the front panel 12 and the back panel 14 adjacent thereto. Similarly, when the rear panel 14 is lifted upward, it is separated from the right panel 15 adjacent thereto, and when the right panel 15 is lifted upward, it is separated from the front panel 12 adjacent thereto. Finally, the front panel 12 is separated from the bottom panel 16. Since the

side panels

12, 13, 14, and 15 are reduced in weight by using the vacuum heat insulating material 21, the work of lifting and separating is easy.

Thus, as shown in FIG. 11, the cold insulation container 10 is separated into the top panel 11, the front panel 12, the left panel 13, the back panel 14, the right panel 15, and the bottom panel 16. Then, as shown in FIG. 12, the separated

side panels

12, 13, 14, 15 are stacked and stored between the separated top panel 11 and the separated bottom panel 16. Thereby, the storage space when not in use becomes compact, and the vacuum heat insulating material 21 of the

side panels

12, 13, 14, 15 is sufficiently protected by the top panel 11 and the bottom panel 16. Further, the separated top panel 11 and bottom panel 16 are temporarily fixed by a fixing tool 60 such as a binding band, a fastener, and a hook-and-loop fastener. Thus, the

side panels

12, 13, 14, and 15 can be reliably protected by the top panel 11 and the bottom panel 16, and can be stored in an upright state.

When assembling the cold insulation container 10 from each panel, the above-described separation steps are performed in the reverse order, so that the top panel 11, the front panel 12, the left panel 13, the back panel 14, the right panel 15, And one cold insulated container 10 is assembled from the bottom panel 16. Here, when the

side panels

12, 13, 14, and 15 are connected in order, the male reinforcing body 31a and the female reinforcing body 31b of the reinforcing body 31 function as a jig, so that the adjacent side faces. The

panels

12, 13, 14, 15 can be accurately and easily connected via the reinforcing body 31.

As described above, according to this embodiment, since both the front panel 12 and the top panel 11 of the cold insulation container 10 can be opened and closed, articles can be easily put in and out regardless of the height position of the installation place. Can do. Further, since the front panel 12 can be opened and closed, articles can be taken in and out of any container with two or more stacked. Moreover, since the heat insulating material panel 20 including the vacuum heat insulating material 21 is used for the

side panels

12, 13, 14, and 15, the panel itself can be thinned and lightened while ensuring high heat insulating properties. . As a result, two or more cold insulation containers 10 can be easily stacked, and the load applied to the lower cold insulation container 10 when two or more are stacked can be reduced.

Moreover, according to this Embodiment, since the cold insulation container 10 is separable into the top | upper surface panel 11, each

side panel

12,13,14,15, and the bottom panel 16, the panel containing the vacuum heat insulating material 21 In case of damage, only the damaged panel can be replaced, and repair is easy.

Further, according to the present embodiment, the separated

side panels

12, 13, 14, and 15 can be stacked and stored between the separated top panel 11 and the separated bottom panel 16. During storage, the

side panels

12, 13, 14, and 15 are protected by the top panel 11 and the bottom panel 16, and the vacuum heat insulating material 21 of the

side panels

12, 13, 14, and 15 is prevented from being damaged. .

In addition, in the example mentioned above, although the reinforcement body 31 was being fixed to the peripheral part of each

side panel

12,13,14,15, it is not limited to this, The reinforcement body 31 is each

side panel

12,13,14, It may be provided in the peripheral part of 15 so that attachment or detachment is possible. Further, when the

side panels

12, 13, 14, 15 themselves have sufficient load resistance, the reinforcing body 31 may be omitted. In this case, the

adjacent side panels

12, 13, 14, and 15 may be appropriately connected by connecting means such as fasteners, hook-and-loop fasteners, and fasteners.

FIG. 13 is a perspective view showing a panel set for an assembly-type cold insulated container according to the second embodiment of the present invention.

As shown in FIG. 13, the assembly-type cold insulation container panel set according to the second embodiment includes a heat insulating member 20 including a vacuum heat insulating material 21 as compared with the first embodiment shown in FIG. It differs in that it further includes a spare side panel 61 that can be exchanged with the right side panel 15.

The side spare panel 61 has the same structure as the right panel 15 having the heat insulating member 20 including the vacuum heat insulating material 21. That is, the side spare panel 61 also has the heat insulating member 20 including the vacuum heat insulating material 21 and can realize a certain heat insulating performance.

In FIG. 13, the same parts as those of the first embodiment shown in FIG.

In the assembly-type cold insulation container panel set shown in FIG. 13, when the vacuum insulation material 21 of the right panel 15 is damaged and the heat insulation cannot be maintained during use of the assembled cold insulation container 10, the insulation is not possible. The right panel 15 can be exchanged with the side spare panel 61 on the spot. Thereby, the fluctuation | variation of the internal temperature of the cold insulation container 10 can be reduced, and deterioration of the quality of the accommodated goods can be suppressed.

In FIG. 13, the side spare panel 61 that can be replaced with the right panel 15 has been described. However, the side spare panel provided in the cold insulation container set is not limited to that for the right panel 15. Although not shown, the cold-insulated container panel set can include at least one side spare panel that can be replaced with any one of the

side panels

12, 13, 14, and 15. In consideration of the use and mode in which the cold and warm container is used, it is preferable to prepare a side spare panel for the side panel that is likely to be damaged. Further, when the top panel 11 or the bottom panel 16 includes the heat insulating member 20 including the vacuum heat insulating material 21, the top panel spare panel replaceable with the top panel 11 or the bottom panel replaceable with the bottom panel 16 is used. A spare panel may be provided.

FIG. 14 is a perspective view showing a panel set for an assembly type cold insulated container according to the third embodiment of the present invention.

As shown in FIG. 14, the assembly-type cold insulation container panel set according to the third embodiment has a front panel 12 that can be exchanged with the front panel 12 as compared with the first embodiment shown in FIG. 11. It is different in that it further includes a replacement panel 63 for the surface and / or a replacement panel 62 for the top surface that can be exchanged with the top panel 11 and cannot be opened and closed.

The front panel 12 that can be opened and closed has a small thickness at a portion related to the opening and closing (in the illustrated example, a portion between the pair of

partial panels

12a and 12b), and heat easily moves. On the other hand, in the front replacement panel 63 that cannot be opened and closed, since there is no portion related to such opening and closing, it is possible to achieve higher heat insulation performance than the front panel 12.

Similarly, in the top panel 11 that can be opened and closed, the portion related to the opening and closing (in the illustrated example, the portion between the pair of

partial panels

11a and 11b) is thin, and heat easily moves. On the other hand, in the top panel replacement panel 62 that cannot be opened and closed, since there is no portion related to such opening and closing, it is possible to achieve higher heat insulation performance than the top panel 11.

14, the same parts as those of the first embodiment shown in FIG. 11 are denoted by the same reference numerals, and detailed description thereof is omitted.

In the assembly-type cold insulation container panel set shown in FIG. 14, for example, when two or more assembled cold insulation containers 10 are stacked or used, or the assembled cold insulation containers 10 are compared with an operator. When installing and using in a high position, the top panel 11 that can be opened and closed of the cold insulation container 10 is replaced in advance with a top panel replacement panel 62 that cannot be opened and closed, thereby ensuring the convenience of putting in and out the article. However, the cold insulation performance can be further improved. Further, for example, when the assembled cold insulation container 10 is used at a relatively low position with respect to the operator, the front panel 12 that can be opened and closed of the cold insulation container 10 is changed to the front replacement panel 63 that cannot be opened and closed. By exchanging in advance, it is possible to further improve the cold insulation performance while ensuring the convenience in taking in and out the article.
