In order to attach the slope member 70A to the container 10A, for example, as shown in FIG. 13, the lid portion 55 of one of the first side walls 40 is opened, and the grip portion 78P behind the slope member 70A is held by hand as described above. It is sufficient to lift the slope member 70A by hanging it, and insert it into the container 10A from the baggage outlet 99. As shown in FIG. Here, although the width of the slope member 70A is slightly larger than the width of the baggage outlet 99, it can be inserted by tilting the slope member 70A slightly in the horizontal direction.

When the slope member 70A is lowered with the lower surface of the slope member 70A substantially horizontal in the container 10A, the slope member 70A is positioned from all sides by the pair of second side walls 30, the pair of base portions 14, the corner reinforcing portions 15, and the like. to the bottom wall 12. As shown in FIG. 14, the lower surface of the contact rib 77 of the slope member 70A contacts the bottom surface 12A of the container 10A, and the plurality of lower surface protrusions 79 of the slope member 70A penetrate the bottom wall 12 vertically. The recesses and protrusions are fitted into the grid-shaped bottom hole 12K. Thus, the assembly of the slope member 70A in the container 10A is completed. By locking the pair of lids 55 in the closed state, the container 10A can be loaded with cargo from above.

The slope member 70A may, for example, be gripped from the top and bottom at the front end and inserted into the luggage outlet 99 from the rear end side. may be inserted into the container 10A from the top opening of the container 10A.

As described above, in the container 10A in which the slope member 70A is superimposed on the bottom surface 12A, the top plate 71 of the slope member 70A becomes a substantial bottom wall, and the top surface 71J of the top plate 71 becomes a substantial bottom surface. As a result, when cargo is stored in the container 10A, as shown in FIG. 9, the lid 55 on the front end side of the slope member 70A is opened to open one cargo outlet 99, and the top plate 71 is tilted. The upper surface 71J guides the baggage to one of the baggage outlets 99 for easy discharge.

The lid portion 55 can be rotated approximately 180 degrees outward from the closed state shown in FIG. If the lid 55 is connected to the upper wall 41 with a string or an S-shaped hook, the lid 55 does not interfere with the work of taking out the luggage.

Further, when the lid portion 55 is closed after the cargo is discharged, the lower end portion of the lid portion 55 faces the horizontal rib 77B at the front end of the slope member 70A as shown in FIG. 15(A). In this case, it is prevented from entering the inside of the container 10A, and an excessive load is prevented from being applied to the hinge member 46 on the upper portion of the lid portion 55.例文帳に追加

When the slope member 70A is not used, as shown in FIG. 17, a plurality of slope members 70A can be stacked and accommodated in one container 10A. Specifically, if the upper slope member 70A on the bottom wall 12 of the container 10A is turned upside down and the top plates 71 are overlapped with each other, the upper slope member 70A will move upward. The bent lower surface becomes horizontal. Then, another slope member 70A can be stacked thereon, and a plurality of slope members 70A can be stacked in the same manner.

Moreover, if at least one of the first side walls 40 is removed from the container 10A, the stacking operation of the slope members 70A within the container 10A can be easily performed. Also, a plurality of slope members 70A may be stacked outside the container 10A in the same manner as inside the container 10A.

In addition, since the slope member 70A has the rear horizontal portion 71Y, when the top plates 71 of the pair of slope members 70A are overlapped with each other, the front end portion and the rear end portion are separated between the top plates 71. A gap 71Z is formed between the two parts. By inserting a finger into the gap 71Z, the overlapping top plate 71 can be easily separated, and the operation of lifting and moving a part of the slope members 70A from the plurality of slope members 70A in a stacked state is facilitated. can be done.

As described above, the container 10A of the present embodiment includes the slope member 70A superimposed on the bottom surface 12A, so that the top surface 71J of the slope member 70A becomes the substantial bottom surface of the container 10A and serves as the baggage outlet 99. Since it is in a downward state, the baggage is guided to the baggage outlet 99 and can be easily discharged. In addition, since the container 10A has a pair of baggage unloading openings 99 through which the slope member 70A can be taken in and out on a pair of side surfaces, the slope member 70A can be attached to and detached from the container 10A with a high degree of freedom. Furthermore, since the slope member 70A has the handle portion 78P at the rear end portion, the slope member 70A can be easily moved using the handle portion 78P. Further, since the slope member 70A has a lower surface protrusion 79 that engages with the bottom surface hole 12K of the container 10A in an uneven manner, displacement within the container 10A is prevented.
