PROBLEM TO BE SOLVED: To provide a folded type multilayer box for export packaging which enables improvement rigidity by adding banding grooves of a cover, a form of vertical plates, and circular guides to improve the operability and indexing ability of a fastening device.SOLUTION: In a packaging box, a folded type division wall 20 includes: two vertical flat plates 23 facing each other; vertical plates 21 fastened to both end parts of each vertical flat plate by hinges; connectors 40, each of which connects the vertical plate with the other vertical plate by a hinge; and pins 41 for fastening the hinges. The vertical plate and the connector form a corner part at one side part so that a fold is made only in one direction. Fastening protrusion plates 25 and fastening protrusion grooves, which are fitted in the fastening protrusion plates, are respectively formed at lower end parts of the vertical flat plates and the vertical plates and upper end parts of the vertical flat plates and the vertical plates. Circular guides 26 are formed at the lower end parts of the vertical plates. Each pin fastening the vertical plate to the connector through the hinge is positioned in the circular guide.SELECTED DRAWING: Figure 3 |
