SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a bottom plate is connected to a lower edge of each pair of side plates, and a lid plate is connected to an upper edge thereof. An outer bottom piece is provided at the lower edge, and a lid receiving piece is connected to the upper edge to form a box body, a lower cushioning material from the bottom plate, an upper cushioning material from the lid plate, and an end cushioning material from the lid receiving piece. Each extends into the inside of the box, the lower cushioning material is a bottom piece connected sequentially from the bottom plate side,
The inner bottom piece, the inner piece and the side piece are bent in a step-like manner, and the sticking piece extending from the leading edge of the side board is bent upward and stuck on the inner surface of the side board, and the bottom plate, inner bottom piece, side plate and inner piece The upper cushioning material is formed by mountain-folding the inter-lid piece and the inner lid piece that are sequentially connected from the lid plate side, and the adhesive piece extending from the leading edge of the inner lid piece faces downward. And affixed to the inner surface of the side plate to form a buffer space between the lid plate and the inner lid piece.The end cushioning material is formed by folding the inner end piece and the end-to-end piece that are sequentially connected from the lid receiving side. The sticking piece extending from the leading edge of the end piece is bent downward and stuck to the inner surface of the end plate to form a buffer space between the end plate and the inner end piece. The plate, the outer bottom piece and the lid receiving piece are respectively erected with respect to the end plate, and each cushioning material is stretched, and the end plate, the outer bottom piece, the lid receiving piece and the end cushioning material are removed. It was to be folded in a flat and folded.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The blank shown in FIG. 1 consists of corrugated cardboard, in which each pair of side plates 1, 1
The end plates 2 and 2 are alternately connected to each other, and a passage piece 3 is provided on the open side edge of one of the side plates 1. A bottom plate 4 is connected to a lower edge of the side plate 1, a lid plate 5 is connected to an upper edge thereof, an outer bottom piece 6 is connected to a lower edge of the end plate 2, and a lid receiving piece 7 is connected to an upper edge. ing. In addition, from the bottom plate 4 to the lower cushioning material 8
However, an upper cushioning material 9 extends from the lid plate 5, and an end cushioning material 10 extends from the lid receiving piece 7.

The lower cushioning material 8 is formed from the bottom plate 4 in order from the bottom plate 4.
1, inner bottom piece 12, inner piece 13, side piece 14, and sticking piece 1
5 are continuously provided. A tongue piece 16 formed by cutting the inner piece 13 protrudes from the center of the distal end of the inner bottom piece 12, and leg pieces 17 are provided on both sides of the base end of the inner piece 13.
The upper cushioning material 9 is provided in order from the lid plate 5, in the order of the lid piece 18, the inner lid piece 1.
9 and the sticking piece 20 are connected. The end cushioning material 10 includes an inner end piece 21 and an end piece 22 in order from the lid receiving piece 7.
And the sticking piece 23 is provided continuously. End plate 2,
A fold line 24 is formed in the outer bottom piece 6 and the end cushioning material 10 in the longitudinal direction, and the fold line 24 forms a cut groove at the inner end piece 21 and the end piece 22.

In order to assemble the blank, as shown in FIG. 2, the side plate 1 and the end plate 2 are bent mutually, and the lower cushioning material 8 is moved upward, the upper cushioning material 9 and the end cushioning material inside. 10 is bent downward, and the adhesive piece 1
5 and 20 are adhered to the inner surface of the side plate 1, and the sticking pieces 23 are adhered to the inner surface of the end plate 2. Further, the passage piece 3 is connected to the end plate 2 on the opposite side.
To form a peripheral wall. These attachments can be easily performed by a machine. In addition, for convenience of assembly, the bottom-to-bottom pieces 11 may be abutted and adhered to each other.

In this manner, with the bottom plate 4 and the lid plate 5 standing against the side plate 1 and the outer bottom piece 6 and the lid receiving piece 7 standing upright with respect to the end plate 2, respectively, the end plate 2, When the outer bottom piece 6, the lid receiving piece 7, and the end cushioning material 10 are folded in two on the mountain fold side, they can be folded flat as shown in FIG. In this state, it does not become bulky during storage, and
It can be efficiently transported to the packaging work place.

At the time of use, the end plate 2, the outer bottom piece 6,
The lid receiving piece 7 and the end cushioning material 10 are restored to a flat plate shape, and as shown in FIGS. 4 to 7, the bottom plate 4 of the lower cushioning material 8, the inner bottom piece 12, Inner piece 1
3 and the side piece 14 are bent in a step-like manner, and the bottom plate 4 and the inner bottom piece 1 are bent.
2 and a buffer space is formed between the side plate 1 and the inner piece 13. This interval is the length of the leg piece 1 protruding with the above-mentioned bending.
It is securely held by the tongue 7 and the tongue piece 16. Further, the outer bottom piece 6 is overlaid and adhered to the lower surface of the bottom plate 4 to form a box having a bottom wall.

In this state, the article is placed on the inner bottom piece 12 and the end cushioning material 1 is bent while the cover receiving piece 7 is bent in the horizontal direction.
The inner end piece 21 and the end-to-end piece 22 at 0 are mountain-folded to form a buffer space between the end plate 2 and the inner end piece 21.

Thereafter, while the cover plate 5 is bent in the horizontal direction, the inter-cover piece 18 and the inner cover piece 19 of the upper cushioning material 9 are mountain-folded to form a buffer space between the cover plate 5 and the inner cover piece 19. At the same time, close the top of the box.

If the ridges of the cushioning members 8, 9 and 10 are creased in advance, they can be quickly assembled from the flat state shown in FIG.

[0014]

As described above, in the packaging box according to the present invention, the lower cushioning material is connected to the lower edge of each pair of side plates via the bottom plate, and the upper cushioning material is connected to the upper edge via the cover plate. At the same time, an end cushioning material is connected to the upper end edge of each pair of end plates via a lid receiving piece, and each cushioning material is bent upward or downward, and the sticking piece at the tip end is attached to the side plate or the end. Since it is attached to the inner surface of the plate, it can be easily manufactured by mechanical attachment.

Further, the bottom plate, the cover plate, the outer bottom piece, and the lid receiving piece connected to the side plate and the end plate are respectively erected to extend the respective cushioning materials, and the end plate, the outer bottom piece, the lid receiving piece, and the end cushioning material are provided. Since it is folded in two and folded flat, it can be assembled quickly from this folded state without bulkiness during transportation and storage.
