FIELD: packaging industry.SUBSTANCE: development of the workpiece of folding carton designed for placement of large articles. The workpiece of folding carton comprises a plurality of the bottom sections and at least four sections of side walls articulated with them. Every two bottom sections are located symmetrically to each other with the line of symmetry, which is the bottom fold line. In the longitudinal direction of the bottom fold line several sections of the bottom are provided. The sections of the side walls are located symmetrically to the bottom fold line. The outer bottom sections have a contour in the shape of a circular segment or a wedge directed toward the bottom inner sections, and in them the fold lines are formed, extending from the point of intersection of the contour having a shape of the circular segment or wedge, with the bottom fold line to the outer edges of the outer sections of the side walls.EFFECT: inventions provide improved folding for easy and compact transportation of the box, while maintaining the bottom rigidity of the box in the assembled position.9 cl, 3 dwg |
