Abstract

Damage to a packing device and a packed object caused by a load is prevented, and a box and the packed object are protected stably. A box of the packing device includes side surface portions, upper flaps, lower flaps, a protrusion, a fixing portion, and interior cushions. The protrusion is formed by folding part of an upper flap. The fixing portion fixes the protrusion such that the protrusion projects from the upper flap. In a state where an object is accommodated in the box, the protrusion is interposed between the upper flap and the packed object, and disperses the load applied to the box.

First claim

The invention claimed is:

1. A packing device for packing an object, comprising:
a box formed of at least one corrugated board sheet for accommodating the object, the box having a top surface portion, a bottom surface portion opposite to the top surface portion and a side surface portion connecting the top surface portion and the bottom surface portion to each other;
wall surface portions being the top surface portion and the bottom surface portion respectively,
each wall surface portion respectively having a protrusion formed by partially folding the corrugated board sheet toward an inside of the box, the protrusion abutting on the object accommodated in the box, wherein the protrusion includes at least two leg portions rising perpendicularly from the wall surface portion in a state where the leg portions oppose each other and a protrusion end coupling tip sides of the leg portions to each other,

wherein a first protrusion and a second protrusion are the protrusions of the top surface portion and the bottom surface portion respectively,
wherein the protrusion ends of the first protrusion and the second protrusion abut on a top surface and a bottom surface respectively of the object,
wherein the first protrusion and the second protrusion are located at the same position with respect to a position in a direction parallel to the top surface portion and the bottom surface portion, and
wherein the first protrusion and the second protrusion are configured to support a part of a load applied to the top surface portion.

2. The packing device for packing an object according to claim 1 , further comprising a fixing portion fixing the protrusion such that the protrusion projects from the wall surface portion.

3. The packing device for packing an object according to claim 2 , wherein
the fixing portion is formed integrally with the protrusion, and abuts on the wall surface portion in a state where the fixing portion is folded from the protrusion.

4. The packing device for packing an object according to claim 2 , wherein
the fixing portion is formed integrally with the wall surface portion, and prevents the protrusion from falling in a state where the fixing portion is folded from the wall surface portion.

5. The packing device for packing an object according to claim 4 , wherein the wall surface portion is formed with
a first incised piece formed into a quadrangular strip-like shape and serving as the protrusion by being folded from the wall surface portion along one side of the quadrangle, and
a second incised piece formed by folding part of the wall surface portion and projecting over an opening formed after the first incised piece is folded to serve as the fixing portion.

6. The packing device for packing an object according to claim 2 , wherein
the fixing portion is formed integrally with the protrusion and abuts on the wall surface portion in a state where the fixing portion is folded from the protrusion, and part of the fixing portion is hooked on an outside of the wall surface portion via a notch formed in the wall surface portion.

7. The packing device for packing an object according to claim 2 , wherein
the wall surface portion is formed with a T-shaped incised piece having a base end side integral with the wall surface portion and a bifurcated tip side, and
the protrusion and the fixing portion are formed by folding the incised piece from the wall surface portion.

8. The packing device for packing an object according to claim 1 , further comprising a cushioning material accommodated in the box together with the object, the cushioning material holding or protecting the object at a position different from a position of the protrusion.

9. The packing device for packing an object according to claim 1 , wherein
the object is an article wrapped in a storage bag.

10. The packing device for packing an object according to claim 1 , further comprising a cushioning material accommodated in the box, the object being fitted in the cushioning material.

11. The packing device for packing an object according to claim 1 , wherein
the wall surface portion is formed with an incised piece.

12. A packing device for packing an object, comprising:
a box formed of at least one corrugated board sheet for accommodating the object, the box having a top surface portion, a bottom surface portion opposite to the top surface portion and a side surface portion connected to the top surface portion and the bottom surface portion;
wall surface portions being of the top surface portion and the bottom surface portion respectively,
each wall surface portion respectively having a protrusion formed by partially folding the corrugated board sheet toward an inside of the box, and a fixing portion fixing the protrusion such that the protrusion projects from the wall surface portion, wherein the protrusion includes at least two leg portions rising perpendicularly from the wall surface portion in a state where the leg portions oppose each other and a protrusion end coupling tip sides of the leg portions to each other,

wherein a first protrusion and a second protrusion are the protrusions of the top surface portion and the bottom surface portion respectively,
wherein the protrusion end of the first protrusion and the second protrusion abut on a top surface and a bottom surface respectively of the object,
wherein the first protrusion and the second protrusion are located at the same position with respect to a position in a direction parallel to the top surface portion and the bottom surface portion, and
wherein the first protrusion and the second protrusion are configured to support a part of a load applied to the top surface portion.

13. The packing device for packing an object according to claim 12 , wherein
the fixing portion is formed integrally with the protrusion, and abuts on the wall surface portion in a state where the fixing portion is folded from the protrusion.

14. The packing device for packing an object according to claim 12 , wherein
the fixing portion is formed integrally with the wall surface portion, and prevents the protrusion from falling in a state where the fixing portion is folded from the wall surface portion.

15. The packing device for packing an object according to claim 14 , wherein the wall surface portion is formed with
a first incised piece formed into a quadrangular strip-like shape and serving as the protrusion by being folded from the wall surface portion along one side of the quadrangle, and
a second incised piece formed by folding part of the wall surface portion and projecting over an opening formed after the first incised piece is folded to serve as the fixing portion.

16. The packing device for packing an object according to claim 12 , wherein
the fixing portion is formed integrally with the protrusion and abuts on the wall surface portion in a state where the fixing portion is folded from the protrusion, and part of the fixing portion is hooked on an outside of the wall surface portion via a notch formed in the wall surface portion.

17. The packing device for packing an object according to claim 12 , wherein
the wall surface portion is formed with a T-shaped incised piece having a base end side integral with the wall surface portion and a bifurcated tip side, and
the protrusion and the fixing portion are formed by folding the incised piece from the wall surface portion.

18. The packing device for packing an object according to claim 12 , further comprising a cushioning material accommodated in the box together with the
