DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. 1 to 4 show an example of the carrying container of the present invention. FIG. 1 is a perspective view of the carrying container, FIG. 2 is a perspective view showing a state during a stacking operation, and FIG. Partial sectional front view, FIG. 4 is a partial sectional front view of a main part showing a stacking state.

First, as shown in FIG. 1, a container 11 for transportation.
Is a square bottom plate 12 and four side walls 20 on the four sides of the bottom plate.
30, 40, 50 and each side wall 20, 30, 4
Flange portions 21 and 3 at the upper opening edges of 0 and 50, respectively.
1, 41, 51 are provided and each side wall 20, 30,
The leg portions 22, 23,
42 and 43 are provided in a protruding manner, and further, the respective flange portions 21 and 3
The recesses 24, 25, 34, 35, 44, 45, 54 corresponding to the leg portions 22, 23, 42, 43 extend from 1, 41, 51 to the inner surfaces of the side walls 20, 30, 40, 50, respectively.
55 are provided respectively.

Further, step portions 26 and 36 for guiding the leg portions are provided on the inner peripheral sides of the flange portions 21 and 31 in the longitudinal direction, and on the inner peripheral sides of the flange portions 41 and 51 in the lateral direction. , And step portions 46 and 56 for fitting leg portions are provided, respectively.

The leg portion and the concave portion are formed in a positional relationship and a size such that the leg portion and the concave portion, which are located in point symmetry with respect to the container center point of the carrying container 11, coincide with each other, and have the same direction. When the shipping containers are stacked on top of each other, the legs and recesses do not match and the legs are placed on the upper surface of the flange (step), and the stacking state occurs, and one shipping container is placed horizontally. When the containers for transportation are stacked one on top of the other in the opposite direction after being rotated 180 degrees in a direction, the legs and the recesses are aligned with each other so that the legs fit into the recesses and become a nesting state. It is set.

The longitudinal flange portion 21,
On the upper surfaces of the stepped portions 26 and 36 provided in 31, there are provided protrusions 61 and 61 having slopes that rise toward the container end portion, respectively. As shown in FIG. 2, the protrusion 61 is a tip of the upper carrying container 11a that slides in a state of being guided by the step portions 26 and 36 when the carrying containers 11a and 11b are slid and stacked. Side transporting container 11 that abuts on the lower end of the leg 22 on the upper side
a is moved upward.

That is, in the projection 61, as shown in FIG. 3, the upper carrying container 11a advances with respect to the lower carrying container 11b, and the bottom tip 12a (leg portion) of the upper carrying container 11a. Immediately before the lower ends (42, 43) of the lower transportation container 11b come into contact with the flange portion 41 of the lower transportation container 11b, by moving the legs 22 of the upper transportation container 11a upward, the bottom end portion 12a of the transportation container 11a is moved. Is slightly raised to avoid contact between the bottom end portion 12a and the flange portion 41, and is formed in a position and shape.

Therefore, when stacking the upper carrying container 11a by sliding the upper carrying container 11a toward the protrusion 61 with respect to the lower carrying container 11b, the bottom end 12a of the upper carrying container 11a and the lower carrying container 11a are stacked. Transport container 1
Since it does not come into contact with the flange portion 41 of 1b, it can be advanced to a predetermined stacking position simply by sliding the upper transport container 11a and pushing it in.

After the leg portion 22 has passed over the protrusion 61, the leg portion 22 returns to the upper surfaces of the step portions 26 and 36 and the leg portions 42 and 43 in the lateral direction are moved as shown in FIG. Since the legs are fitted into the stepped portions 46, 46, respectively, a stable stacking state can be maintained.

When the step portion for guiding the leg portion is not provided on the inner circumference of the flange portion, the protrusion 61 may be provided so as to project upward on the upper surface of the flange portion. Further, the protrusion 61 is formed by a slope or a curved surface having an appropriate rising angle in the container sliding direction, but there is no problem even if the opposite side is a vertical wall as shown in the figure.

[0016]

As described above, the carrying container of the present invention can prevent the bottom end of the upper container and the inner periphery of the opening edge of the lower container from coming into contact with each other when sliding and stacking.
