Abstract
A packing box of a polygonal tube shape to pack an object includes a plurality of corners and a plurality of holding portions. The plurality of corners are creases along which a flat plate is folded. The plurality of holding portions protrude inward of the packing box, hold the object, and are disposed at positions corresponding to at least two corners of the plurality of corners on one end in a longitudinal direction of the packing box and at positions corresponding to at least two corners of the plurality of corners on the other end in the longitudinal direction of the packing box that is a direction in which the polygonal tube shape extends. The at least two corners on the one end are different from the at least two corners on the other end.
Claims11
A packing box of a polygonal tube shape to pack an object, the packing box comprising:
- a plurality of corners that are creases along which a flat plate is folded;
- and
- a plurality of holding portions to protrude inward of the packing box and hold the object, the plurality of holding portions disposed at positions corresponding to at least two corners of the plurality of corners on one end in a longitudinal direction of the packing box and at positions corresponding to at least two corners of the plurality of corners on another end in the longitudinal direction of the packing box that is a direction in which the polygonal tube shape extends,
- wherein the at least two corners on the one end are different from the at least two corners on said another end.
A method of assembling a packing box to pack an object, the method comprising:
- folding a flat plate along creases of the flat plate to form the flat plate into a polygonal tube shape having a plurality of corners;
- and
- protruding a plurality of inter-slit portions, each of which is interposed between two slits in parallel with each other in a direction intersecting the creases when the packing box is in a state of the flat plate, inward of the polygonal tube shape to form a plurality of holding portions to hold the object,
- wherein the plurality of holding portions are at positions corresponding to at least two corners of the plurality of corners on one end in a longitudinal direction of the packing box that is a direction in which the polygonal tube shape extends, and at positions corresponding to at least two corners of the plurality of corners on another end in the longitudinal direction, and the at least two corners on said another end are different from the at least two corners on the one end in the longitudinal direction.
