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.
Claims20
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,
- the plurality of holding portions are a plurality of inter-slit portions to protrude inward of the packing box, and each of the plurality of inter-slit portions 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, and
- the two slits are inclined with respect to a direction perpendicular to the creases.
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,
- the packing box has a square tube shape, and
- the plurality of holding portions includes:
- two holding portions on the one end in the longitudinal direction at positions corresponding to two corners on a diagonal line among the plurality of corners;
- and
- two holding portions on the other end in the longitudinal direction at positions corresponding to two corners on a diagonal line among the plurality of corners, which are different from the two corners corresponding to the two holding portions on the one end.
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,
- each of the plurality of holding portions is at a position shifted from an edge on the one end or the other end in the longitudinal direction to a center of the packing box in the longitudinal direction, and
- the plurality of holding portions holds the object within a range between both edges of the packing box in the longitudinal direction.
