DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for an electronic device, and more particularly to an improvement in a packaging container (packing box) formed by assembling a single corrugated board for storing the electronic device.

[0002]

2. Description of the Related Art Recently, as a packaging material for packaging containers, from the viewpoint of environmental protection, a material which generates polluting gas when burned,
There is a tendency not to use materials that are difficult to reuse (recycle) and those that are reusable but difficult to separate.

[0003] Therefore, foamed polystyrene or a cushioning sheet with air bubbles (air cap), which has been frequently used as a cushioning material when packaging electronic equipment, is no longer used, and paper or processed paper is used as a packaging material. Corrugated board is considered useful. As the packaging container made of this paper material or corrugated cardboard, a paper material or corrugated cardboard plate assembled in a conventional box shape, pulp mold (compression molding), a corrugated cardboard pad or corrugated cardboard is bonded to a box shape. There are things.

[0004]

However, in the case where a paper material or a corrugated board is assembled in a conventional box shape, there is generally room for improvement in strength. For example, it is required that the packaged product containing the electronic device is not damaged even if it is dropped from a height of 1 m. However, if the cardboard is thin, it is easily broken or dented.

Although it can be considered that this problem can be solved by stacking several corrugated cardboard plates and making them thicker, it is actually difficult to sufficiently absorb the impact at the time of dropping, and this is not practical. In addition, pulp molds (compression molding), corrugated cardboard pats, and corrugated cardboard bonded to a box form tend to increase equipment costs and assembly costs for processing, are inferior in assembly workability, and require storage space. There is a disadvantage.

The present invention has been made under such circumstances, and it is preferable from the viewpoint of environmental protection, and provides an inexpensive packaging container in which protection of electronic equipment to be packaged is ensured, the structure and assembly are simple, and the cost is low. Aim.

[0007]

In order to solve such problems, the present invention provides a rectangular bottom plate made of a corrugated cardboard,
The bottom plate is provided with first and second side plate pairs that protrude from two opposite sides of the bottom plate and are integrally folded and assembled. The first side plate pair is formed by valley-folding upward from the opposing sides of the bottom plate, and is folded back in a state where a buffer space is formed inside the container on the way.

[0008] The second pair of side plates is provided with a first side plate from both sides.
Abutting pieces protruding from each other in the same direction as the side plate pair, and from the opposite side of the bottom plate, are folded downward in a mountain-like manner and then folded in a plurality of places to be valley-folded and raised inside the container. The first side plate pair is folded back in a state in which a buffer space is formed, and the contact pieces are brought into contact with the outer surface from both sides of the folded first side plate pair, and both ends are connected to the first side plate. Locked in pairs.

According to the present invention, the first pair of side plates may be formed such that the rising portions thereof are wide and cover the end portions of the second pair of side plates. Further, in the present invention, the second pair of side plates is provided with flaps projecting in the same direction as the contact piece from both sides on the tip side from the projecting position of the contact piece, and these flaps provide a buffer space inside. It is also possible to adopt a configuration in which the formed flaps are folded inward, and the tip ends of the flaps are further folded in a state in which a buffer space is formed on the inside, and the folded back flaps are locked.

[0010]

According to the present invention provided with such means, the first pair of side plates is valley-folded upwardly from each other to stand up, and then turned inward at a plurality of locations in the middle to form a buffer space inside the container. Is formed, the second side plate pair is mountain-folded downward from the bottom plate to each other and folded down, and then sequentially valley-folded at a plurality of locations to be raised and folded, so that the bottom plate rises and a buffer space is formed inside the container, When the contact piece of the second pair of side plates abuts on the outer surface of the first pair of side plates and is engaged with the outer surface, the box shape is maintained.

In the configuration in which the wide portion is partially formed in the first side plate pair, the end of the second side plate pair is covered with the wide portion. Further, in the second pair of side plates, in a configuration in which flaps are provided on both side portions on the tip side from the projecting position of the contact piece, a double buffer space is formed inside the second pair of side plates.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 9 are views showing an embodiment of a packaging container according to the present invention. In particular, FIGS. 1, 3 and 4 are assembly drawings of the packaging container, FIG. 2 is a development view, and FIGS. FIG. 8 and FIG. 9 are perspective views.

Are formed parallel to each other. Therefore, as shown in FIG. 1 and FIG. 3, each of the opposing first side plate pairs 3 is valley-folded upward at the boundary with the bottom plate 1 and rises, and the slit tip portion and the width-changed portion are valley-shaped. By folding and folding back to the bottom plate 1 side, and valley-folding the front end portion in the direction of the first pair of side plates 3 at the boundary portion with the bottom plate 1, as shown in FIGS. A flat buffer space A can be formed inside the container 3, that is, inside the container.

In this specification, the term "valley fold" refers to a state in which the paper surface has a valley shape in FIG. Therefore, the way of folding the first and second side plate pairs on the outer shape is different.

Returning to FIG. 2, the second pair of side plates 5 has contact pieces 17 extending in the direction of the first pair of side plates 3 from both sides on the way. A locking hole 19 is formed through the distal end near the side. In the second side plate pair 5, a stitch that can be mountain-folded is formed at a portion indicated by a dashed line, that is, at a boundary between both long sides of the bottom plate 1.

The opposing first and second side plate pairs 3 and 5 are also protected by the buffer areas A and B, and the five surfaces of the stored electronic device are protected from the outside. Therefore, for example, if the electronic device is housed so as to be sandwiched between the two packaging containers 21 according to the present invention and fastened with a tape or the like, the entire electronic device is protected, and the electronic device is protected in good condition against external pressure. it can. Of course, if the first and second side plate pairs 3 and 5 are formed to be long to form a deep packaging container 21 and also covered with a buffer such as cardboard and fixed with tape or the like, one packaging container 21 can be used. Electronic devices can be stored and protected.

For example, the packaging container 21 containing the product is
Even if it falls from the height, it does not damage the product, and can sufficiently absorb the impact at the time of falling. Moreover, since it is formed of a corrugated board which is inexpensive, reusable and easy to separate in the natural world, it is inexpensive and is preferable from the viewpoint of environmental protection.

Further, the assembling work is easy because it can be assembled from a single corrugated cardboard, and the left, right, front and rear are symmetrical, and can be easily assembled manually or by a machine. Further, the buffer space B of the second pair of side plates 5 is hidden by the wide portion 7 of the first pair of side plates 3 and the contact piece 17, and the ends of the first and second pair of side plates 3 and 5 are closed. Hard to crush.

However, when packaging an electronic device formed of a plurality of modules, as shown in FIG.
It would be better to wrap the electronic device in a suitable cushioning body 23 made of a cardboard board and put it in a cardboard box 25 sandwiched between two packaging containers 21 according to the present invention. In addition, the locking hole 15
Is a hole for accommodating the protrusion of the packaged object, and may be omitted if there is no protrusion, or may be formed in another place.

By the way, although the streaks for mountain folds and valley folds are not essential, assembling is easier if the streaks are formed.
