<p>PROBLEM TO BE SOLVED: To provide a buffer structure for a packed article having a high strength against a fall from a corner part without increasing the used amount of a packing material.SOLUTION: A packed article is formed by folding adjoining side walls 2 and 3 formed to merge into a bottom wall 1 individually from the bottom wall 1 so as to wind sequentially continued outside panels 21 and 31, top plates 22 and 32 and inside panels 23 and 33. From the end part of the inside panel 23 of one side wall 2 of the adjoining side walls 2 and 3, a diagonal plate 27 extends through an oblique valley fold line 26. The diagonal plate 27 is folded back on the valley fold line 26 and is wound in an inclined state by the other side wall 3, so that the diagonal plate 27 extends to the diagonal inside of the other side wall 3. The adjoining side walls 2 and 3 are connected to each other, and the other side wall 3 is reinforced by the diagonal plate 27, so that the shape retention against the fall from the corner part is improved to suppress the increase of the used amount of the packaging material is suppressed more than that of the case where another cushioning material is used.</p> |
