PROBLEM TO BE SOLVED: To provide a connected structure of laminated corrugated boards, which can be easily assembled from a flat state to a various use state with a reduced area of material for use.SOLUTION: A border 2 is placed on a laminated corrugated board 1 formed of a lamination of corrugated boards 1a at a distance away from the edge. The laminated corrugated boards 1 are connected to each other by bonding the surfaces of each portion between the edge and the border 2, so that a connected structure of the laminated corrugated boards can be folded along the border 2. The corrugated boards 1a of the laminated corrugated board 1 are off-set stacked to form a single layer part 3 formed of one sheet of corrugated board 1a only in the range from the edge of the laminated corrugated board 1 to the border 2. The single layer parts 3 of the laminated corrugated board 1 are bonded to each other at the opposite side of the lamination of the corrugated boards 1a so that the laminated corrugated boards 1 are connected to each other, allowing for easy folding along the border 2 to an angle of 90°, 180°, or even 270° for assembling into a square cylindrical shape or a U-shape. |
