Further, as shown in FIG. 5, the lower frame member 23 is formed in a substantially U-shaped cross section having a concave strip 5 </ b> A having an opening taper on one side. As shown in FIGS. 3 and 5, the vertical frame member 24 and the upper frame member 25 are formed in a substantially hat-shaped cross section in which the flange portions 4 a extend at both ends of the narrow taper-shaped protruding strips 3 A and 3 B toward the tip. Has been.

  In the front and rear panels 21, 22, the ridges that connect the ridges 3 </ b> A of the vertical frame member 24 and the ridges 3 </ b> B of the upper frame member 25 to the joints between the vertical frame member 24 and the upper frame member 25. A corner frame member (not shown) having a gap is interposed.

  The other parts of the front and rear panels 21 and 22 are the same as those of the floor panel 10, so the same parts are denoted by the same reference numerals and description thereof is omitted.

  The side panel 30 includes a pair of rectangular surface plates, that is, an inner surface plate 1 and an outer surface plate 2, and three types of frame members that are mounted between the side portions of the surface plates 1 and 2, that is, the lower side, A lower frame member 31 having a recess 5B on the inner surface of the lower side, and a vertical line 3A provided on the inner surface of both vertical sides on the vertical side perpendicular to the lower frame member 31 and on the end surfaces of the front and rear panels 21, 22 A pair of vertical frame members 32 having recesses 5C that can be slidably fitted to each other, an upper frame member 33 having protrusions 3C on an end surface of the upper side, upper surface plates 1 and 2, frame members 31, 32, And the heat insulating material 7 made of, for example, foamed polyurethane, which is filled in the space formed by 33.

In this case, the length of the one piece 34 a on the vertical frame member 32 side constituting the reinforcing member 34 is formed to be greater than the thickness of the side panel 30. Thus, by forming the one piece 34a of the reinforcing member 34 to be equal to or greater than the thickness of the side panel 30, when the panels 10, 21, 22, 30, 40 are stacked after disassembly, the panels stacked on the side panel 30, for example, The front and rear panels 21 and 22 can be housed inside the reinforcing member 34, and the side panel 30 and the front and rear panels 21 and 22 can be integrated in a stacked state.

  In addition, since the other part in the side panel 30 is the same as the floor panel 10, the same code | symbol is attached | subjected to the same part and description is abbreviate | omitted.

  On the other hand, the lid panel 40 is mounted between a pair of surface plates, i.e., the inner surface plate 1, the outer surface plate 2, and the side portions of the surface plates 1 and 2, and the front panel and the rear panel are disposed on the lower surfaces of the four sides.

Is longer than the thickness of the lid panel 40. Thus, by forming the length of the hanging piece 44 to be equal to or greater than the thickness of the lid panel 40, when the panels 10, 21, 22, 30 and 40 are stacked after disassembly, A panel, for example, the rear panel 22 stacked in the lower stage by the corner reinforcing member 42 can be accommodated on the inner side of the corner reinforcing member 42, and the lid panel 40 and the rear panel 22 can be integrated in a stacked state. For example, a packing 45 made of synthetic rubber is fixed to the inner peripheral side of the adjacent portion between the fixed piece 43 and the hanging piece 44 (see FIGS. 4 and 5).

  In addition, since the other part in the cover panel 40 is the same as the floor panel 10, the same code | symbol is attached | subjected to the same part and description is abbreviate | omitted.

  The heat insulation container is assembled by assembling the floor panel 10 configured as described above, the front and rear panels 21 and 22, and the pair of side panels 30 and the lid panel 40.

Next, the other side panel 30 is assembled by slidingly fitting the concave strip C of the other side panel 30 to the convex strip 3A on the other side of the front and rear panels 21 and 22. At this time, the packing 8 of the floor panel 10 and the packing 8A of the side panel 30 are elastically deformed and brought into close contact with the sliding of the side panel 30 (step 14-5: see FIG. 12). After assembling the front and rear panels 21, 22 and the both side panels 30, the four rounds of the lid panel 40 are formed on the convex strips 3 B on the upper side of the front and rear panels 21, 22 and the convex strips 3 C on the upper side of the side panel 30. The concave strip 5D provided on the lower surface is fitted to close the lid panel 40 (step 14-6: see FIG. 13). Then, the front and rear panels 21 and 22 and the side panel 30 are fixed by engaging the surface fastener engaging body 63 and the surface fastener engaging receiving body 64 of the first surface fastener 61, and the second surface fastener. The surface fastener locking body 65 and the surface fastener locking receiving body 66 of 62 are engaged to fix the lid panel 40 and the front and rear panels 21 and 22 (step 14-7: see FIG. 2). Before closing the lid panel 40, the front and rear panels 21, 22 and the side panel 30 are fixed by engaging the surface fastener engaging body 63 and the surface fastener engaging receiving body 64 of the first surface fastener 61. You may do (refer FIG. 13).

  According to the heat insulating container assembled as described above, the ridges 3, 3A, 3B, 3C provided on the floor panel 10, the front and rear panels 21, 22, the side panel 30, and the lid panel 40 having heat insulating properties, respectively. And the concave strips 5, 5A, 5B, 5C, 5D are assembled and assembled, so that they can be easily assembled and the heat insulation can be improved. Further, after the article 80 is transported, it can be disassembled by performing the reverse operation of the above assembling procedure. The disassembled floor panel 10 (the pallet 15 remains fixed integrally), the front and rear panels 21, 22, the side panel 30 and the lid panel 40 can be stacked and transported or stored.

  Next, the stacking procedure of the floor panel 10, the front and rear panels 21, 22 after being disassembled, the side panel 30, and the lid panel 40 will be described with reference to the flowchart shown in FIG. 15 and FIG. First, the inner surface plate 1 of one side panel 30 is placed on the floor panel 10 (the pallet 15 remains fixed integrally) (step 15-1). Next, the inner surface plate 1 of the front panel 21 is placed on the side panel 30 (step 15-2). Next, the inner surface plate 1 of the other side panel 30 is placed on the front panel 21 (step 15-3). Next, the inner surface plate 1 of the rear panel 22 is placed on the side panel 30 (step 15-4). Finally, the outer surface plate 2 of the lid panel 40 is placed on the rear panel 22 (step 15-5). At this time, the plate-like packing 90 is interposed on the four peripheral sides between the rear panel 22 and the lid panel 40 (see FIG. 16). In this way, by interposing the plate-like packing 90 on the four peripheral sides between the rear panel 22 and the lid panel 40, the “adhesion” caused by the contact between the inner surface plates 1 formed of galvalume steel plates having smooth surfaces. Therefore, it is possible to prevent damage due to a situation that is difficult to be fixed and separated, such as “displacement” and “rubbing”.

  As described above, the front panel 21, the one side panel 30, the rear panel 22, the other side panel 30, and the lid panel 40 are stacked in this order on the floor panel 10, so that the reinforcing member 34 provided on the side panel 30 becomes an obstacle. It can be stacked without becoming. Further, the front and rear panels 21, 22, the side panel 30 and the lid panel 40 are accommodated inside the panel holding pillars 18 arranged upright at the four corners of the floor panel 10 and are stacked on the top panel. Since the provided corner reinforcing member 42 covers the outer side of the upper end of the panel holding column 18, the stacked floor panel 10, front and rear panels 21, 22, side panel 30 and lid panel 40 are connected to the reinforcing member 34. Protected by the corner reinforcement member 42, there is no risk of damage even if it collides with an obstacle during transportation.

  In the above description, the front panel 21, the one side panel 30, the rear panel 22, the other side panel 30, and the lid panel 40 are stacked on the floor panel 10 in this order. Instead, the order of the front and rear panels 21 and 22 may be reversed as long as the front and rear panels 21 and 22 and the inner surface plate 1 of the side panel 30 are placed on top.
