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.
Claims21
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.
