  When disassembling the container C1 assembled in a box shape, first, the locking projection b1a of the elastic tongue b1 constituting the fitting block member B1 formed on the long wall member 2 and the short wall member 3 is firstly applied. The rod S is inserted into the formed recess b1a ″, and the free end of the elastic tongue b1 is elastically deformed in the direction of the peripheral wall 1b of the bottom member 1 as shown in FIG. The locking projection b1a formed on the elastic tongue b1 is discharged from the locking through hole 1g4 ′ formed in the partition plate portion 1g4 constituting the fitting member 1g formed on the bottom member 1, and thereafter The container body C1 ′ is raised to release the connection state between the container body C1 ′ and the bottom member 1. For the operation of releasing the connection state between the bottom member 1 and the container body C1 ′, an elastic tongue piece is used. The free end portion of b1 is elastically deformed in the direction of the peripheral wall portion 1b of the bottom member 1. As described above, the elastic tongue b1 is provided with the elastic deformation suppressing projection b1b ′ so as to prevent the elastic tongue b1 from being excessively elastically deformed and damaged, as shown in FIG. As described above, the elastic deformation suppressing projection b1b ′ is brought into contact with the peripheral wall portion 1b of the bottom member 1 so that excessive elastic deformation of the elastic tongue b1 is suppressed and the elastic tongue b1 is not damaged. Yes.

  The disassembly work of the long wall member 2 and the short wall member 3 constituting the container main body C1 'can be performed by the reverse process of the assembly work of the long wall member 2 and the short wall member 3 described above. That is, the fitting block member formed in the short wall member 3 by lowering the short wall member 3 with respect to the long wall member 2 or by raising the long wall member 2 with respect to the short wall member 3. The vertical portion 3e2 of 3e is discharged from the fitting space A2 located in the sub space portion A1 ′ formed in the vertically long connecting portion 2b of the long wall member 2, and then, from the sub space portion A1 ′ of the long wall member 2, By pulling out the fitting block member 3e of the short wall member 3, the long wall member 2 and the short wall member 3 can be disassembled. In this way, the container C1 is disassembled into five members, that is, one bottom member 1, two long wall members 2, and two short wall members 3.

  As described above, the assembling / disassembling container C1 is composed of five members, that is, one bottom member 1, two long wall members 2, and two short wall members 3. First, A cylindrical container body C1 ′ is formed by the two long wall members 2 and the two short wall members 3, and then the cylindrical container body C1 ′ is connected to the bottom member 1 to assemble and disassemble. The container C1 is assembled into a box shape, and the cylindrical container body C1 ′ is pulled out from the bottom member 1 of the assembling / disassembling container C1 in a state of being assembled into a box shape. By releasing the engaged state with the wall member 3, the assembling / disassembling container C1 is disassembled into five members including one bottom member 1, two long wall members 2, and two short wall members 3. Assembling and disassembling of the assembling / disassembling container C1 can be performed in a short time and It can be carried out easily.

  Further, since the assembling / disassembling container C1 is constituted by five members, that is, one bottom member 1, two long wall members 2, and two short wall members 3, the assembling / disassembling in an assembled state. Compared with the storage space of the possible container C1, the storage space of the disassembled members 1, 2, and 3 can be greatly reduced.

  When the width of the long wall member 2 of the assembling / disassembling container C1 is widened or narrowed and the width of the assembling / disassembling container C1 on the long wall member 2 side is changed, It is not necessary to change the short wall member 3 only by changing the width of the long side peripheral wall 1b1 of the peripheral wall portion 1b constituting the bottom member 1.

  A plurality of assembling / disassembling containers C1 in the assembled state having the above-described configuration are placed on the pallet P as shown in FIG. 25, and then the plurality of assembling / disassembling containers C1 are banded. When tightening with T, the band T is not the periphery of the long wall member 2 and the short wall member 3, but the band plate-shaped corner vertical ribs formed on the bottom member 1 as shown in FIG. 1e and the vertical rib 1f between the corners.

  As described above, the strip-shaped corner vertical ribs 1e and the corner-to-corner vertical ribs 1f formed on the bottom member 1 of the assembled and disassembled container C1 in a plurality of assembled states placed on the pallet P are provided. Since the band T is configured to be hung, the side wall is deformed or the hinge part between the bottom bank and the side wall as compared with the folding container that tightens the side wall by the band as in the conventional folding container. Can be prevented from being damaged.

  In addition, as described above, the strip-shaped corner vertical ribs 1e and the corner-to-corner vertical ribs formed on the bottom member 1 of the plurality of assembled and disassembled containers C1 placed on the pallet P are assembled. Since the band T can be hung on the 1f, the band takes care of the deformation of the side wall and the damage of the hinge part between the bottom bank and the side wall, like a conventional folding container that tightens the side wall. Since the band T can be tightened without doing so, the workability of the band T tightening work is improved.

  Further, of the vertical ribs 1f between the corners formed on the opposing long side peripheral wall 1b1 and the opposing short side peripheral wall 1b2 constituting the peripheral wall portion 1b of the bottom member 1, the long side peripheral walls 1b1 and the short side peripheral walls 1b2 are formed. It is preferable that at least one formed in the above is composed of the intermediate band-shaped portion 1f1, the upper triangular portion 1f2, and the lower triangular portion 1f3 as described above. With this configuration, when the band T is hung on the bottom member 1, even if the band T is displaced in the vertical direction of the bottom member 1, the band T extends along the upper triangular portion 1f2 or the lower triangular portion 1f3. Therefore, the band T is guided to the intermediate band-shaped portion 1f1, so that the band T can be surely arranged substantially in parallel.
