Abstract

PROBLEM TO BE SOLVED: To provide a cushioning material made of cardboard capable of being rapidly assembled from a state of low bulk. SOLUTION: Edge panels 6 are connected to the respective peripheral edge sides of a square bottom panel 5 and erected from the bottom panel 5 to be mutually joined in an outwardly inclined state to form each of trays 1-4. These trays 1-4 are joined and, at the time of transport or keeping, they are arranged flatly and, when used, the adjacent trays 1-4 are bent to abut the edge panels 6 thereof to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material made of cardboard for packing.

[0002]

2. Description of the Related Art For example, when packing a computer main body, a video deck, or the like, conventionally, cardboard or other cardboard is wound into a tubular shape instead of a molded cushioning material such as styrofoam which has an adverse effect on the environment due to disposal. A fixed cushioning material is used.

[0003]

However, the cardboard cushioning material as described above cannot be quickly assembled at the time of use, and must be assembled in advance.
There is a problem of bulkiness during transportation and storage.

Accordingly, an object of the present invention is to provide a cardboard cushioning material that can be quickly assembled from a low bulk state.

[0005]

In order to solve the above-mentioned problems, a cardboard cushioning material according to the present invention is characterized in that an edge plate is continuously provided on each side of a peripheral edge of a rectangular bottom plate, and each edge plate is erected from the bottom plate. Adjacent edge plates are joined in an outwardly inclined state to form a tray, a plurality of trays are joined, these trays are arranged flat during transportation and storage, and the adjacent trays are bent by bending when used. The edge plates were to be abutted.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a blank of a cardboard cushioning material M is composed of four trays 1 to 4 connected in a T-shape. Are arranged in a line, and the portion of the tray 4 is located beside the portion of the tray 2.

In each of the trays 1 to 4, an edge plate 6 is continuously provided on each side of the peripheral edge of the bottom plate 5, and sticking pieces 7 are provided at both ends of one opposed edge plate 6. The bottom plate 5 of each of the trays 1, 3, and 4 is provided with a locking piece 8 by cutting an inner portion, and the bottom plate 5 of the tray 2 is provided with an engagement hole 9 by cutting out three sides.

In order to assemble the cushioning material M from this blank, as shown in FIG. 2, each edge plate 6 is erected from the bottom plate 5 and the sticking pieces 7 are adhered to the adjacent edge plates 6, and these edges are attached. The trays 1 to 4 are formed by joining the plates 6 in a state inclined outward.

Here, since the sticking piece 7 is easily stuck by a machine, the cushioning material M can be efficiently produced and supplied.

Further, in this state, the trays 1 to 4 are lined up flatly, and the trays 1 to 4 have a tapered shape of constriction. And storage can be performed efficiently.

When packing the product, as shown in FIG.
The cushioning material M is quickly assembled by bending by 0 °, butting the edge plates 6 and pushing the locking pieces 8 into the locking holes 9 to fix the trays 1 to 4.

Then, as shown in FIGS. 4 and 5, the product G is placed so that the bottom plate 5 of the trays 1 to 4 comes into contact with the product G.
When the cushioning material M is set at each of the four corners and stored in the outer box, the product G is held in a state where a space is secured around the cushioning material M and is protected from impact.

In place of the engagement between the locking pieces 8 and the locking holes 9, a pre-seal adhesive is applied to the outer surface of the edge plate 6, which is bonded only by abutting the applied surfaces, and this adhesive is used. May be used to fix the trays 1 to 4.

In this example, four trays 1 to 4
Although one having two or three trays is shown, it is also possible to connect two or three trays along the edge or corner of the product.

[0015]

As described above, the cardboard cushioning material according to the present invention has a structure in which a plurality of trays are connected, so that the trays can be efficiently transported and stored in a low-volume state in which the trays are arranged flat, and the trays can be placed adjacent to each other. By bending the tray to be bent and abutting its edge plates, it can be assembled quickly in use.
