BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a coupling tool that joins side plates of a container-like container having an open top surface.
[0002]
[Prior art]
Generally, plastic containers formed by injection molding are used as container containers for storing industrial equipment products such as motors and pumps, and other industrial equipment products, as well as pottery and glass products for transportation, transportation, storage, etc. A container made of plastic is used. Recently, container-like containers formed by folding low-cost corrugated cardboard sheets are also seen.
[0003]
By the way, this type of container can be stacked in multiple stages (hereinafter referred to as stacking) even when the articles are stored, and the container is unloaded so that it does not become bulky when it is emptied, that is, when not in use. Is desired to be low (hereinafter referred to as nesting).
[0004]
This type of transport container is well known by Japanese Utility Model Laid-Open No. 4-10015. Hereinafter, this conventional technique will be described with reference to the drawings.

[0006]
As shown in FIG. 16, a conventional container-like container has four side plates 2, 3, 4, 5 standing from the outer edge of the bottom plate 1 so as to have a taper that gradually expands upward, and has an opening edge at the top. The continuous flange portion 6 is integrally connected. The side plates 2 and 3 are symmetrically formed with bulging portions 7, 8, 9, and 10 connected to the opening edge, and the support legs 11 and 12 are projected on the outer surfaces of the side plates 2 and 3, respectively. 15 and 16 are provided with steps. The support legs 11 and 12 have different shapes, that is, the support legs 12 are formed wider than the width of the support legs 11.
[0007]
In the above-described configuration, as shown in FIG. 17, the upper container-like container 14 is rotated by 180 ° with respect to the lower container-like container 13 so that the above-mentioned support legs 15 and 16 become the lower container-like container 13. The bulging portions 7, 8, 9, and 10 are fitted into the inner recesses, and the support legs 11 and 12 are supported by the flange 17 of the lower container 13 and can be nested. And the height dimension at the time of nesting can be made into about 1 / 2H.
