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

  FIG. 7 is an enlarged cross-sectional view of a portion surrounded by a one-dot chain line denoted by reference symbol A in the heat insulating container body 10A of FIG. FIG. 8 is an enlarged cross-sectional view of a portion surrounded by an alternate long and short dash line with a symbol B in the heat insulating container body 10A of FIG.

  As shown in FIGS. 7 and 8, 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. 7 and 8, 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. 11A and FIG. 11B are cross-sectional views showing the vacuum heat insulating material 21.

  As shown in FIGS. 11A and 11B, 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. 11 (a), spaces are formed at both ends of the core material 21a in the jacket material 21b. However, as shown in FIG. 11 (b), the core in 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. 7 and FIG. 8, 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 it can exhibit a desired heat insulating property. 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.

  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 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 heat insulating container body 10A as a whole becomes heavy, and it may be difficult to handle the heat insulating container body 10A. 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 heat insulating 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 insulating function of the vacuum heat insulating material 21 can be further exhibited, and the weight and dimensions of the heat insulating container main body 10A. 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 heat insulating container body 10A 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. 7 and 8, the protective material 23 is formed such that each side is larger than each side of the additional heat insulating material 22. 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.

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.

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. 8, 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. 7 and 8, 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. 7 and 8, 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, and 15 are connected to each other. The corner foam heat insulating material 222 covers the inner surfaces of the four corners of the heat insulating container body 10A. Thereby, the heat insulation of four corners of the heat insulation container main body 10A 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.
