Flaps 20, 22, and 23 are formed on the four sides of the rectangular side plate portion 19, a flap 21 is further formed at the tip of the flap 20, a flap 24 is further formed at a tip of the flap 23, and both sides of the flap 24 are formed. The flap 25 is formed. The flap 20 is folded along a curve T12.
At the fold curve T13 formed substantially at the center of the flap 20, and further folded back at the first elastic leg 26.
To form The flap 21 is bent substantially at right angles to the near side at a folding curve T14. The flaps 22 and 23 are bent at right angles to the near side at the folding curves T15 and T16, the flap 24 is folded back at the folding curve T17, the flap 25 is folded at the folding curve T18, and the second elastic legs The part 27 is formed. The flap 19 is formed with a slot H4 for inserting a convex portion 13 of a first cushioning material 2a, which will be described later. Holes H3 and H5 are formed.

Next, the structure of the first cushioning member 2a and the cushioning member 2 shown in the development view of FIG. 4 and the perspective view of FIG. 2 will be described. Flaps 5, 1 on the four sides of the rectangular side plate 4
1 and 15 are formed, and flaps 12 and 16 are formed on both sides of the flaps 11 and 15. The flaps 5, 11, 1
At the end of the flap 5, convex portions 6, 13, 17 are formed. On one side of the flap 5, a slot H formed in the flap 11 is formed.
2 is formed so that the slot H2 does not become a notch on both sides of the tip of the flap 11.
A flap 14 is formed and folded back toward the user so as not to obstruct the insertion of the projections 10 and 13. A handle hole H1 is formed in the side plate portion 4, and a reinforcing flap 4a is formed on one side of the handle hole H1 so as to be folded back toward the front side at a folding curve T4 to be reinforced. The flap 5 is formed with a notch 7 for inserting and locking the partial cushioning material 2c and notches 8 and 9 for preventing interference with other parts when assembled to the cushioning material 2. The flap 15 is formed with a notch 18 so that the second elastic leg 27 can easily absorb an impact.

The second cushioning material 2b is replaced with the first cushioning material 2b.
a on the front side of the side plate portion 4 of FIG.
1 and 15 are bent at right angles to the near side at folding curves T1, T5 and T20, and the flaps 12 and 16 are folded at folding curves T8 and T8.
At T19, the second cushioning material 2b is bent at substantially right angles to the outside of the flap 21 to form two folding curves T2, T3, T6, T7, T formed substantially at the center of the flaps 5, 11, and 15.
10 and T11, each of which is bent toward the near side by approximately 90 ° and turned back to the side plate portion 19 side of the second cushioning material 2b, and inside the turned back, the flaps 12, 16, 21 and the first elastic leg portions 26 are provided. And the second elastic leg 27, and the partial cushioning material 2c is provided in the cutouts 7 on both sides of the flap 5.
Of the flaps 5, 11, 15 and the protrusions 6, 13, 17 formed at the tips of the flaps 5, 11, 15 are inserted into the slots H3, H
4. The buffer material 2 is assembled by inserting it into H5. A slit H6 for inserting a guarantee 28 is formed between the fold curve T6 of the flap 11 of the first cushioning material 2a and the side plate portion 4. The warranty card 28 inserted through the slit H6 indicates the thickness of the first elastic leg 26 formed between the side plate 4 of the first cushioning material 2a and the side plate 19 of the second cushioning material 2b. Is securely stored in the minute gap. Also, by attaching the stored flap 29 of the warranty card 28 to the upper surface of the flap 11 of the first cushioning material 2a, it is possible to clearly indicate that the warranty card 28 is stored when unpacked.

In the above configuration, the buffering action of the buffer 2 will be described. In the packaging of products, it is necessary to consider three-dimensional impacts of up, down, left, right, front and back as drop impact directions. The upward direction is mainly the flap 11
Is folded back at the folding curves T6 and T7, and the presence of a cavity inside causes a buffering action. In the downward direction, a buffering action is generated mainly by the elasticity of the folded portion of the second elastic leg 27. In the left and right side directions, a buffering action is generated mainly by the elasticity of the folded portion of the first elastic leg 26. The front-rear direction is mainly the flaps 5, 12, 16, 2
The folding action of 1 causes a buffer action. Further, the partial cushioning material 2c abuts the stepped portion 1a on the rear side of both sides of the indoor unit 1 to evenly buffer the entire side surface, thereby improving the buffering performance mainly in the left and right side direction.

[0017]

As described above, according to the present invention,
A packing device which is easy to dispose of and has a buffering performance which is not inferior by holding it in accordance with the shape of the cushioning surface of the packaged object, and which can easily store a warranty card or the like.
