Next, the first fixing tab 15 and the second fixing tab 16 are bent inward along the fifth fold line 17 and the sixth fold line 18, respectively. Next, the first fixing tab 15 and the second fixing tab 16 are inserted into the hole 23 of the intermediate sheet 3 and the hole 19 of the bottom wall 4. Thereby, the assembly of the tray 1 is completed.

When the tray 1 is assembled, it is as follows. The first side wall 5 and the second side wall 6 are perpendicular to the bottom wall 4. The first upper wall 7 and the second upper wall 8 are parallel to the bottom wall 4. The first fixing tab 15 and the second fixing tab 16 come out of the hole 23 and the hole 19 due to the frictional force between the outer periphery of the first fixing tab 15 and the second fixing tab 16 and the inner periphery of the hole 23 and the hole 19. It is prevented. The first fixing tab 15 and the second fixing tab 16 are in contact with each other.

In the case of this embodiment, the following effects can be obtained at the time of logistics transportation or cargo handling. Since the intermediate sheet 3 is wrapped by the outer sheet 2, the position of the intermediate sheet 3 is regulated by the first side wall 5 and the second side wall 6. For this reason, it can prevent reliably that the position shift of the intermediate sheet 3 arises. Therefore, the deformation of the tray 1 can be reliably suppressed. Therefore, it can suppress reliably that a to-be-packaged object, ie, a product, mutually contacts and is damaged.

The first fixing tab 15, the second fixing tab 16, the hole 19 and the hole 23 are examples of fixing means for fixing the first upper wall 7 and the second upper wall 8. In the present embodiment, the first upper wall 7 and the second upper wall 8 can be reliably fixed with a simple configuration. If it is this Embodiment, the position of the intermediate sheet 3 can also be fixed because the 1st fixing tab 15 and the 2nd fixing tab 16 will be in the state fitted to the hole 23 of the intermediate sheet 3. FIG. In the present embodiment, the first fixing tab 15 and the second fixing tab 16 are fitted not only into the hole 23 of the intermediate sheet 3 but also into the hole 19 of the bottom wall 4, so that the first upper wall 7 And the 2nd upper wall 8 can be fixed more reliably. Instead of such a configuration, the bottom wall 4 may not have the holes 19. That is, the first fixing tab 15 and the second fixing tab 16 may be fitted only in the hole 23 of the intermediate sheet 3. Further, instead of the configuration in which all the intermediate sheets 3 are provided with the holes 23, only some of the intermediate sheets 3 on the upper layer side may be provided with the holes 23.

In the present embodiment, the first fixing tab 15 and the second fixing tab 16 are fitted together in the hole 19 and the hole 23. Instead of such a configuration, the first fixing tab 15 and the second fixing tab 16 may be fitted in separate holes.

The fixing means in the present invention is not limited to the above configuration. For example, the following fixing means may be used. The lower surfaces of the first upper wall 7 and the second upper wall 8 may be bonded to the upper surface of the uppermost intermediate sheet 3 with an adhesive or a double-sided adhesive tape. The first fixing tab and the second fixing tab each having a flange portion are connected to the first upper wall 7 and the second upper wall 8, respectively, and the flange portions of the first fixing tab and the second fixing tab are connected to the lower surface of the bottom wall 4. It may be engaged. On the contrary, the first fixing tab and the second fixing tab having the flange portion are connected to the bottom wall 4, and the flange portions of the first fixing tab and the second fixing tab are connected to the first upper wall 7 and the second upper wall 8. You may engage with the upper surface of each.
