Abstract:
1. A packing implement for goods transportation comprising: a baseboard and a holding sheet adapted for storing an article in an outer casing, wherein: the baseboard is a rectangular board for supporting the article to be transported at a fixed position, the baseboard including: a center part, the center part having parallel first sides and parallel second sides, and wherein: the baseboard has folding parts demarked by fold lines marked on an upper surface of the base board at both ends and both side parts of the center part of the base board, respectively; the folding parts include rising parts, falling parts, and shape retaining parts; the rising parts comprise parts folded upward from both end edges of the second side of the baseboard and the falling parts comprise parts folded back downward from both side edges of the first side of the baseboard respectively, each falling part has a free edge to which the holding sheet is secured so that downward folding of the falling parts draws the holding sheet taut across the upper surface of the center part, and is constituted by a leg part orthogonal to the center part and a bottom part which is bent parallel with the center part, and a buffer space corresponding to a rising height of the leg part of the falling part, is formed by the leg part bent so as to be orthogonal to the center part and the bottom part bent parallel with the center part; both ends of the leg part are at acute angles and contiguous with the rising parts, respectively, both end parts of the baseboard being contiguous with the rising parts are wider than a center part of the baseboard, respectively, triangular parts of both ends of the leg parts are projected to side of the baseboard, respectively, and buffer spaces are formed below a lower surface of the center part, when the falling parts are folded downward and the rising parts are folded back upward, respectively; the shape retaining parts comprise four corner parts which remain between end edges of the rising parts and end edges of the falling parts, respectively, which are contiguous with the rising parts and the falling parts, respectively, are folded parallel with the rising parts when the falling parts are bent downwardly, respectively, and are erected to hold the falling parts bent when the rising parts are folded upwards, respectively, and polygonal openings are formed in the base board, each polygonal opening being located at a front end of the triangle part of the end of the leg part where the fold lines for the rising part, the falling part, and the shape retaining part, join, each polygonal opening having each of its vertices intersectively coincident with a fold line, and each polygonal opening serves as a starting point when folding the baseboard to prevent the folding parts from deviating from the fold lines, and after folding, eliminates a pointed portion to prevent the outer casing from damage.
