BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG.
1 is a perspective view of the present invention, FIG. 2 is a longitudinal sectional side view taken along line AA in FIG. 1, FIG. 3 is a cross-sectional plan view taken along line BB in FIG. 1, and FIG. FIG. 5 is a vertical sectional side view showing a portion of a reinforcing member in a use state of the present invention, and FIG. 6 is a perspective view of an assembled container using the present invention. As shown in FIG. 1, the present invention relates to a connecting member of an assembling container for connecting adjacent side walls of a box constituting an assembling container at a corner portion, and an assembling container assembled by the connecting member. The coupling member 1 includes an outer wall member 2 disposed on an outer peripheral surface of a corner portion of the side wall plates 12 and 13 adjacent to each other, and an inner wall member disposed on an inner peripheral surface of a corner portion of the side wall plates 12 and 13 adjacent to each other. 3 comprises a holding portion 4 formed so as to open downward, and a claw portion 6 provided on the inner surface of the outer wall member 2 and the inner wall member 3 of the holding portion 4. Adjacent side walls 12 and 13 of the assembling container 11 are fitted from above, and the claw portions 6 provided on the inner surfaces of the outer wall member 2 and the inner wall member 3 of the holding portion 4 are adjacent to each other. 12 Beauty 1
3 to fit into the recess 14 provided in the
Are fixed to each other at the corners of the assemblable container 11.

On the other hand, in the assembling type container 11, side wall pieces 12 and 13 are erected on four sides of a square bottom, and the side wall plates 12 and 13 are overlapped to form a box. Therefore, the holding portion 4 opened downward of the coupling member 1 is provided.
Is inserted from above (in the direction of the arrow in FIG. 1) into the corner of the assemblable container, and the holding portion 4 of the coupling member 1 is overlapped with the corner side wall plates 12 and 13 of the box constituting the assemblable container 11. The claw portions 6 provided on one or both of the outer wall member 2 and the inner wall member 3 of the holding portion 4 are attached to the side wall pieces 12 and 13 of the box constituting the assembling container 11. Engaging with the recessed portion 14 provided (see FIG. 4), the side walls 12 and 13 of the body are sandwiched by the elasticity of the holding portion 4 of the coupling member 1, and the side walls 12 and 1
By combining the three, a prefabricated container as shown in FIG. 6 is formed. At this time, the inclined surface 7 provided at the lower end of the claw portion 6 is fixed to the side wall plate 1 at the corner of the box by the connecting member 1.
When the overlapped portions 2 and 13 are sandwiched, the claw portions 6 are guided to the concave portions 14 of the side wall plates 12 and 13 of the box to facilitate engagement. Reference numeral 8 denotes a bent portion of the connecting member 1, and 9 denotes a flange of the connecting member 1, which serves as a guide member for stabilizing the containers when they are stacked. 16 is a side wall plate 12 of a box body
Alternatively, it is a handle provided in the unit 13.

Further, in the assembly type container, in order to increase the strength of the container, a U-shaped reinforcing member 15 is previously fitted over the entire length of the upper edge of the assembly type container 11. . However, when storing and transporting articles in an assemblable container, the handhold 16 provided on the side wall of the container may not be gripped, and the reinforcing member 15 may often be gripped. In some cases, the container containing the article may fall off from the side wall plate 12 or 13 of the box, causing an accident. However, in the present invention, the holding portion 4 of the coupling member 1 is fitted to both ends of the reinforcing member 15 and both ends of the reinforcing member 15 are fixed. When storing and transporting, the reinforcing member 15 cannot move upward even if the reinforcing member 15 is gripped, so that the reinforcing member 15 comes off the side wall plate 12 or 13 of the box. Thus, it is possible to reliably prevent an accident that the assembled container falls.

The distance 5 between the holding portions 4 of the coupling member 1 is set on the side wall plate 12 of the assemblable container 11.
3 is superposed, or the side walls 12 and 13
It is a matter of course that the thickness is changed so as to correspond to each of them according to the difference in the thickness of the joint members 1 and the gap between the joining member 1 and the side wall plate of the assembling container 11 so as not to form a gap.

In the present invention, the claws 6 provided on one or both of the inner surface of the outer wall member 2 and the inner surface of the inner wall member 3 of the holding portion 4 of the coupling member 1 may be provided on one side or both sides. In order to surely connect the side walls 12 and 13 of the box body to the concave portion 14, it is preferable to provide both the outer wall member 2 and the inner wall member 3 of the holding portion 4.

The recess 9 provided in the side wall plates 12 and 13 of the assemblable container 11 may be a simple depression or a through hole penetrating the side wall plate.

The above description is based on the assembly type container 11.
Although the description has been given of the case where the side wall plates 12 and 13 are overlapped with each other, the present invention can also be applied to a case where the side walls 12 and 13 are not overlapped and both ends thereof are butted.

[0014]

As described above, according to the present invention, when assembling a prefabricated container, the side wall plates can be connected by one-touch with a connecting member, and the connection by screws or metal fittings is not required. Can be achieved. In addition, since the joining member can be made of the same material as the container, the use as a container is abolished, and when recycled as a synthetic resin material, there is no dissimilar material. The effect is great, such as cost reduction.
