PROBLEM TO BE SOLVED: To reduce the number of parts for packing materials and improve the packing workability, by integrally forming cushion materials protecting the top face and the back face of an article to be packed. SOLUTION: A cushion plate 7 is arranged in parallel with the top face of an article 3 to be packed so as to go across the upper external box 1 back and forth and further, it is bent at folding lines 9 positioned at the ridge line 8 of the top face and the rear face of the article 3 to continuously extend to the rear face side of the article 3 and cover the rear face of the article 3 with the extension 7a. In this way, not only the top face of the article but also the rear face can be protected. And the number of parts can be reduced and the workability can be improved well in comparison with the case in which the protective part of the top face and the protective part of the rear face are formed by different members respectively. |
