A large number of fixed walls 17 are integrally molded on the outside of the support step 9 in accordance with the latching recesses 15, and through holes 19 are formed in the fixed wall 17 so as to substantially coincide with the latching recesses 15. It is formed.
In the frame 3, the length of one frame side 3a is set to l1, and the length of the other frame side 3b is set to l2. A box member 4 is attached to the frame 3, and the box member 4 is formed of a resin corrugated board 5 having a large number of hollow parts. The resin corrugated board 5 has a substantially rectangular shape, and each corner is cut out according to the height of the box shape. When the resin corrugated board 5 is bent at the broken line position shown in FIG.
It is formed into a box shape consisting of a, 5b, 5c, 5d and a bottom plate 5e. Among them, one side plate 5a, 5b has a lateral length l1 corresponding to one frame side 3a of the frame 3, and the other side plate 5c, 5d has a length l2 corresponding to the other frame side 3b of the frame 3. It is formed to have a slightly longer lateral length l3. A large number of through holes 21 are formed at the upper end of each of the side plates 5a, 5b, 5c, and 5d in correspondence with the through holes 19. The through hole 21 is integrally punched out using a press device (not shown).

The fixing pin 7 inserted into the through hole 19 and the through hole 21 has a shaft portion 7a having an outer diameter corresponding to the inner diameter of the through hole 21, and a protrusion 7b that engages with the inner surface of the fixing wall portion 17. and a head 7c that comes into contact with the outer surface of the fixed wall 17. When the fixing pin 7 is inserted into the through hole 19 and the through hole 21, the shaft end of the shaft portion 7a is latched in the latching recess 15. Further, the protrusion 7b engages with the inner surface of the fixing wall 17, and the fixing pin 7 is prevented from coming out from the through hole 19 and the through hole 21.

The second method for assembling the container 1 having the above configuration is as follows.
This will be explained with reference to FIGS. 4 to 4.

In FIG. 3 and FIG. 4 showing an enlarged view of the corner of the assembled resin corrugated board 5, the resin corrugated board 5 with the corner notched is bent at the broken line position shown in FIG. side plates 5a, 5b, 5c, 5
d and a bottom plate 5e. At this time, the horizontal length of the side plates 5a and 5b is a length l1 corresponding to the long side of the corresponding frame 3, and the side plates 5c and 5d are
The horizontal length of the frame 3 is slightly longer than the short side of the corresponding frame 3, l3.

As shown in FIG. 2, the upper ends of each of the side plates 5a, 5b, 5c, and 5d bent as described above are inserted between the hanging part 13 and the fixed wall part 17, and then attached to the frame 3. , the resin corrugated board 5 is temporarily fixed. At this time, since the lengths of the side plates 5c, 5d are set longer than the lengths of the corresponding frame sides 3a, when the side plates 5a, 5b, 5c, 5d are temporarily attached to the frame 3, one side plate 5a, The upper end of the side plate 5b stands up in an inclined state so as to be located slightly inside the upper ends of the other side plates 5c and 5d. In addition, the through hole 19, the through hole 21, and the latching recess 1
5 are almost the same. Then, the fixing pin 7 is inserted through the through hole 19 of the fixing wall part 17 to the frame 3 and the resin corrugated board 5 which are temporarily fixed as described above.
When the head part 7c is inserted into the through hole 21 until it comes into contact with the outer surface of the fixed wall part 17, the shaft end of the shaft part 7a is caught in the latching recess 15, and the protrusion 7b is inserted into the inner part of the fixed wall part 17. Engage with the sides. As a result, the resin corrugated board 5 is supported by the frame 3 via the shaft portion 7a, and the fixing pin 7 is prevented from coming off by the protrusion 7b, thereby forming the box-shaped container 1.

Therefore, when each side plate 5a, 5b, 5c, 5d of the box member 4 is fixed to the frame 3, the other side plate 5a, 5b has its upper end above the side plate 5c, 5d that stands up almost vertically. Side plates 5c, 5d
It is tilted so that it is located inward from both upper ends of. Therefore, both end surfaces of one side plate 5a, 5b are brought into contact with the inner surface of the other side plate 5c, 5d.
It has high assembly strength. Furthermore, even when the side plates 5a, 5b swell outward due to an external force acting on the side plates 5a, 5b from the inside when a product is stored in the container 1, the side plates 5a, 5b and the side plates 5
This prevents a gap from forming between c and 5d.
Intrusion of foreign matter such as dust can be avoided. This allows products to be transported or conveyed with superior quality.

In the above explanation, the resin corrugated board 5 is attached to the frame 3 via a separate fixing pin 7, but as shown in FIG. The resin corrugated board 5 may be fixed to the frame 31 by inserting the through hole 21 of the resin corrugated board 5 into a fixing pin 35 having a pair of claw portions 35b facing each other via the fixing pin 35a.
