Foldable container having corner locking structure

Abstract

The present invention relates to a foldable container which can be folded or unfolded through application of torsion bars, the foldable container having a structure for rigidly coupling the edge portions of an upper plate, wherein the upper plate is completely detachably coupled to side panels. The foldable container according to the present invention comprises: posts provided in a vertical direction at both sides of a front panel and a rear panel to bear the load of the container; a torsion bar provided at each of the lower ends of the side panels, the front panel, and the rear panel; and a corner locking structure which couples the upper plate to the rear panel and the side panels at upper corner portions, so that the corner portions are rigidly coupled in an unfolded state of the container.

Description

Technical field [0001] The present invention relates to a folded folding container that can be used in a torsion bar, which is used to firmly bind the structure of the upper plate corner portion, in particular, to the following technique, that is, the lower end of the side wall panel of the container The rod can easily fold the side wall panel while removing the upper plate and recombined with the upper plate, and firmly lock the corner portion in order to firmly maintain the container settlement in the foldable container. Background technique [0002] Typically, the container is formed by a large box formed by the iron plate, mainly for transporting goods. The above container is widely used because of the following advantages, that is, is formed from a size having a predetermined specification, thereby easily saving and handling the goods, but not only, it is also possible to protect the goods being loaded inside. A single container is transported by specialized large cargo vehi...
