Description

  The present invention relates to a cold insulation container using a vacuum heat insulating material.

  The cold insulation container is used for managing the internal temperature in the physical distribution field, for example. Generally, the cold insulation container is suppressing the movement of the heat | fever inside and outside a container because the panel has a heat insulation member.

  Recently, a cold insulation container using a vacuum heat insulating material for a panel has been proposed. Vacuum insulation material has significantly higher insulation performance per unit thickness than general-purpose foam insulation materials, so the panel can be made thin while ensuring the desired cold insulation function, reducing the weight of the cold insulation container and saving space. Can be achieved.

  Patent Document 1 includes four peripheral wall portions that are connected to each other so as to be bendable, two lid portions that are connected to bendable to upper ends of two opposing peripheral wall portions, and the lid portion. There are two bottom surfaces connected in a foldable manner to the lower ends of the two peripheral wall portions connected to each other, and a vacuum heat insulating material is included inside each surface. Further, Patent Document 1 describes that the two peripheral wall portions facing each other can be folded into valley folds.

  In Patent Literature 2 and Patent Literature 3, a cylindrical wall body having four wall surfaces having a vacuum heat insulating material, a lid body fitted to one end edge portion of the wall body, and fitted to the other end edge portion of the wall body. There is described a base having a mating base, in which the wall, the lid, and the base are separable from each other. 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 all the containers containing a vacuum heat insulating material, Comprising: A fixed heat insulation performance is realizable. In addition, space saving can be realized by folding when not in use.

  However, in Patent Document 1, there is not enough strength to stack two or more because of the structure of each surface. In addition, since the opening and closing direction is limited to the top surface, if two or more are stacked, articles cannot be taken in and out of the lower container.

  In Patent Document 2 and Patent Document 3, there is a description that two or more can be stacked, but since the wall body only holds the vacuum heat insulating material between the two cardboard materials, the container is enlarged. As the amount of storage increases, the strength of the wall of the lower container becomes insufficient. In addition, since the opening and closing direction is limited to the top surface, articles cannot be put in and out of the lower container with two or more stacked.

  However, when a vacuum heat insulating material is used for the side panel, there is a problem that the supporting force of the panel is reduced because the thickness is reduced. Furthermore, if the vacuum heat insulating material breaks and the vacuum breaks, the heat insulating performance will be abruptly lowered, so that an excessive load should not be applied. However, when the opening / closing direction of the container is set to the side, it is necessary to support the weight with the side panel other than the opened side panel. In addition, in a state where two or more containers are stacked, naturally, a considerable weight is applied to the lower container.

  The present invention has been made in consideration of the above points. It is an object of the present invention to be able to stack two or more side panels without using a large load on a side panel in which a vacuum heat insulating material is used. An object of the present invention is to provide a cold insulated container that can be used.

  The present invention is a cold insulation container comprising a top panel, a front panel, a left panel, a back panel, a side panel having a right panel, and a bottom panel, and the front panel is openable and closable. Each of the side panels has a heat insulating member including a vacuum heat insulating material, and a reinforcing body extending in the entire height direction of these side panels is provided between adjacent side panels.

  Preferably, the top panel, the side panel, and the bottom panel are separable from each other, and the front panel, the left panel, the back panel, and the right panel of the side panel are Each can be separated through a reinforcing body. More preferably, the separated side panels can be stacked and stored between the separated top panel and the separated bottom panel. Furthermore, it is preferable to further include a fixture for temporarily fixing the separated top panel and the separated bottom panel.

  Preferably, the reinforcing body is a male reinforcing body provided at a side edge of one side panel and a female mold engaging with a male reinforcing body provided at a corresponding side edge of an adjacent side panel. And a reinforcing body.

  According to the present invention, it is possible to stack two or more cold insulation containers without applying a load to the side panel in which the vacuum heat insulating material is used. Articles can be taken in and out.

  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.

  As shown in FIG. 2, one front panel 12 of the cold insulation container 10 can be opened and closed. In the present embodiment, the front panel 12 that can be opened and closed has a pair of partial panels 12a and 12b. The pair of partial panels 12a and 12b are connected to the adjacent left side panel 13 and right side panel 15 via a reinforcing body 31, respectively, and can be bent on the outside of the reinforcing body 31 via a folding line extending in the entire height direction. It has become. Thereby, a pair of partial panel 12a, 12b comprises the double door of the cold insulation container 10. Thereby, the space of the front-back direction (depth direction) required when opening the front panel 12 can be reduced.

  A female surface fastener (not shown) is provided on the outer surface of the side edge of one partial panel 12a, and the outer surface of the side edge of the other partial panel 12b is in contact with the female surface fastener. A possible male hook-and-loop flap 51 is provided.

Is provided. Such a pocket-shaped storage part 41 is not necessarily provided on the inner surface of the top panel 11 and the side panels 13, 14, 15, and the pocket-shaped storage part 41 is provided on the inner surface of the bottom panel 16. Also good.

  Next, the structure of the four side panels 12, 13, 14, 15 will be described in detail.

  FIG. 5 is an enlarged cross-sectional view of 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 FIGS. 5 and 6, the four side panels 12, 13, 14, and 15 each include a heat insulating member 20 including a vacuum heat insulating material 21.

  More specifically, 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 laminated on the inner surface of the vacuum heat insulating material 21, and an outer surface of the vacuum heat insulating material 21. And a laminated protective 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.

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

  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 the core material. A heat insulating material that is obtained by reducing the pressure inside the outer covering 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, the core of the jacket material 21b. The covering material 21b may be brought into close contact without forming a space at both ends of the material 21a.

  Returning to FIG. 5 and FIG. 6, as the additional heat insulating material 22 and the peripheral portion foam heat insulating material 221, 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 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.

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 has 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 disassembling work and the assembling work can be reduced.

  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.

  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.

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 an organic material such as polypropylene is preferably 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 h33mm of each leg part, and the thickness are 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.

  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 each side panel 12, 13, 14, 15 has the heat insulating member 20 including the vacuum heat insulating material 21, it is lightweight and easy to separate.

  In this way, the cold insulation container 10 is separated into the top panel 11, the four side panels 12, 13, 14, 15 and the bottom panel 16. 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. Further, the separated top panel 11 and bottom panel 16 are temporarily fixed with a fixing tool such as a binding band, a fastener, and a hook-and-loop fastener. Thereby, when it is carried in a non-use state, the vacuum heat insulating material of the side panel is sufficiently protected.

  Next, when the cold insulation container 10 is used, the above disassembly process is performed in the reverse order, so that the top panel 11, the four side panels 12, 13, 14, 15, and the bottom panel 16 One cold insulation container 10 is assembled. 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 the present embodiment, the reinforcing body 31 extending in the entire height direction of the side panels 12, 13, 14, 15 is provided between the adjacent side panels 12, 13, 14, 15; When stacking two or more containers 10, the load of the upper container 10 is supported by the reinforcing body 31 of the lower container 10, and the load on the side panels 12, 13, 14, 15 of the lower container 10 is significantly reduced. Is done. Therefore, two or more containers 10 can be stacked without imposing a large load on each side panel 12, 13, 14, 15. Moreover, it can be set as the structure which can open and close the front panel 12 by reducing the load to each side panel 12, 13, 14, 15 and, thereby, any container 10 remains in the state where two or more are stacked. It is also possible to put in and out articles. Moreover, the heat insulation panel 20 containing the vacuum heat insulating material 21 can be employ | adopted for each side panel 12,13,14,15 by reducing the load to each side panel 12,13,14,15. Thus, the internal temperature can be maintained satisfactorily.
