Buffering member

1. A buffering member interposed between a packaging box having a bottom plate and side plates stood along peripheral edges of the bottom plate and a first packed article, the buffering member comprising:

a placement section on which the first packed article is to be placed; and

at least one pair of leg pieces to be connected to a pair of opposing edges of the placement section via folding lines,

wherein the at least one pair of leg pieces is folded downward along the folding lines with an obtuse angle with respect to the placement section and then lower edges of the at least one pair of leg pieces are engaged with boundaries between the bottom plate and the side plates of the packaging box,

wherein the at least one pair of leg pieces includes a pair of holding pieces which are raised in a direction opposite to a folding direction of the at least one pair of leg pieces when the at least one pair of leg pieces is folded downward along the folding lines, and

the pair of holding pieces is provided such that the first packed article abuts against opposing faces of the pair of the holding pieces.

2. The buffering member according to claim 1 ,

wherein the placement section has a substantially rectangular shape, the placement section includes:

a first end part provided at one end side in a long-side direction;

a second end part provided at another end side in the long-side direction; and

a central part provided between the first end part and the second end part and

wherein the first packed article is placed on the first end part and the second end part.

3. The buffering member according to claim 2 ,

wherein the central part of the placement section is formed with a recessed part configured to store a second packed article by being folded downward.

4. The buffering member according to claim 2 ,

wherein the at least one pair of leg pieces is connected to each of the first end part and the second end part.

5. The buffering member according to claim 2 ,

wherein the central part has a width equal to a width of the bottom plate of the packaging box in a direction perpendicular to the long-side direction and

the first end part and the second end part each have a width smaller than the width of the central part.

6. The buffering member according to claim 1 ,

wherein the first packed article is a toner cartridge to be attached to an image forming apparatus and

the buffering member includes a pair of holding pieces which are raised in a direction opposite to a folding direction of the at least one pair of leg pieces when the at least one pair of leg pieces is folded downward along the folding lines,

a space interposed by the pair of holding pieces is formed between an end face in the long-side direction of the toner cartridge and the side plate of the packaging box opposing to the end face in the long-side direction of the toner cartridge and

a movable part and a protrusion provided on the end face in the long-side direction of the toner cartridge is stored in the space.

7. The buffering member according to claim 1 ,

wherein the placement section has a rectangular shape and

the at least one pair of leg pieces is connected to a pair of opposing long edges of the placement section via the folding lines.

8. The buffering member according to claim 1 ,

wherein the packaging box has flaps which are connected via folding lines along upper edges of opposing side plates opposing in a long-side direction of the placement section, the flaps being folded inward along the folding lines so as to overlap on the corresponding side plates.

9. A buffering member interposed between a packaging box having a bottom plate and side plates stood along peripheral edges of the bottom plate and a first packed article, the buffering member comprising:

a placement section on which the first packed article is to be placed; and

at least one pair of leg pieces to be connected to a pair of opposing edges of the placement section via folding lines,

wherein the first packed article is a toner cartridge to be attached to an image forming apparatus, and

the buffering member includes a pair of holding pieces which are raised in a direction opposite to a folding direction of the at least one pair of leg pieces when the at least one pair of leg pieces is folded downward along the folding lines,

a space interposed by the pair of holding pieces is formed between an end face in the long-side direction of the toner cartridge and the side plate of the packaging box opposing to the end face in the long-side direction of the toner cartridge and

a movable part and a protrusion provided on the end face in the long-side direction of the toner cartridge is stored in the space.

10. A buffering member interposed between a packaging box having a bottom plate and side plates stood along peripheral edges of the bottom plate and a first packed article, the buffering member comprising:

a placement section on which the first packed article is to be placed; and

at least one pair of leg pieces to be connected to a pair of opposing edges of the placement section via folding lines,

wherein the at least one pair of leg pieces is folded downward along the folding lines with an obtuse angle with respect to the placement section and then lower edges of the at least one pair of leg pieces are engaged with boundaries between the bottom plate and the side plates of the packaging box,

wherein the placement section has a substantially rectangular shape, the placement section includes:

a first end part provided at one end side in a long-side direction;

a second end part provided at another end side in the long-side direction; and

a central part provided between the first end part and the second end part, and

wherein the first packed article is placed on the first end part and the second end part,

the central part of the placement section is formed with a recessed part configured to store a second packed article by being folded downward, and

the first end part, the second end part and a bottom face of the recess are flat parallel to the bottom plate.
