Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard package for packing objects to be packaged, such as electric appliances such as air conditioners.

[0002]

2. Description of the Related Art When shipping a completed product, a package is used for reasons such as convenience of transportation and protection of the product.
As a conventional package, when storing a packaged object, by providing both ends positioning members made of Styrofoam between the outer box made of cardboard and the packaged item, and fixing the packaged item, during transportation, etc. A package having a structure for protecting an internal packaged object from such an impact is known.

[0003] However, styrofoam used as a positioning member at both ends is generally expensive because a mold is required for its forming process. Further, when disposing of this package, it is necessary to separate the outer box made of corrugated cardboard from the positioning member at both ends made of styrene foam from the viewpoint of recycling resources of recent interest, which is complicated. Further, the cost and labor required for recycling the styrofoam are very large as compared with cardboard.

[0004] For this reason, a cardboard package having a positioning member at both ends made of the same cardboard as the outer box has been used, as disclosed in JP-A-2000-327037. In this package made of corrugated cardboard, a cushioning structure is formed by bending one corrugated cardboard several times, and protects the internal packaged object from impact. By using the cardboard packaging body of this configuration, it is possible to pack the product at a lower cost, and it is not necessary to separate it during recycling.

[0005]

However, the cardboard package using the positioning members at both ends having the above-mentioned structure has no buffer function in the vertical direction. Further, since the buffer effect is intended to be obtained by the space formed by bending the corrugated cardboard several times, the buffer effect is extremely small, and does not extend far to the buffer effect by the conventional both-side positioning members made of polystyrene. For this reason, it is not possible to sufficiently protect the internal packaged object from the impact at the time of transportation, and there is a possibility that the electrical product as the packaged item may be damaged.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a corrugated cardboard package using a corrugated cardboard both-end positioning member having the same effect as that of a conventionally used polystyrene foam both-end positioning member.

[0007]

According to the present invention, there is provided a cardboard packaging body in which an outer box made of cardboard in which an article to be packed is packed, and both ends of the article to be packed are positioned so as not to move in the outer box. A pair of corrugated cardboard both end positioning members, each of the pair of both end positioning members has a cylindrical shape having an opening on one surface, and an object to be packed is fitted into the cylinder of the both end positioning members from the opening. And is fitted into the outer box (claim 1).

According to this configuration, the article to be packed is inserted into the cylindrical positioning members at both ends and then inserted into the outer box, so that it has a buffering function in all directions, up, down, left, right, front and back. . In addition, since all the packages are made of cardboard, the packages can be manufactured at very low cost. Also, when the used corrugated cardboard package is discarded, there is no need to separate the cardboard, which saves time and effort, thereby promoting the reuse of resources.

The cardboard package of the present invention is formed, for example, in a rectangular tube shape by folding and assembling the cardboard at both ends, and further, the surface of the cardboard cardboard that comes into contact with the object to be packed is formed by folding the cardboard. It is preferable that a buffer function is exhibited by being superimposed (claim 2).

[0010] With this configuration, the cushioning function is ensured by stacking the cardboards, and the items to be packed are sufficiently protected. Also, by making both end positioning members each cylindrical shape,
Ease of assembly is achieved.

In the cardboard package according to the present invention, it is desirable that the positioning member at both ends is provided with a buffer member made of cardboard inside.

With this configuration, the assembling work is facilitated. This is a structure in which the both end positioning members include a buffer member that exhibits a buffer function, thereby improving workability and shortening the operation time as compared with the case where the both end positioning members themselves are folded back many times. That's why. It is also effective to further simplify the assembling work by separating the cushioning member into several members.

In the cardboard package of the present invention, for example, it is desirable that the cushioning member exerts a buffering function by folding and stacking the cardboard.

As in the present configuration, by corrugating the cardboard a plurality of times and superimposing it on multiple layers, a greater buffering effect can be obtained. As a result, it becomes possible to exhibit a much better shock-absorbing function as compared with the conventional cardboard package, and a buffer effect equivalent to that of the conventional styrene foam can be obtained.

In the cardboard package of the present invention, it is preferable that a handle for packing and unpacking is formed by, for example, forming a hole in the opening edge of the positioning member at both ends. .

With this configuration, during packing and unpacking operations,
The workability of fitting and taking out the positioning members at both ends into which the article to be packed is inserted into the outer box is improved, and at the same time, the work time is shortened.

In the cardboard package of the present invention, for example, it is preferable that a mark indicating the direction of fitting into the outer box is provided on one surface of the both-end positioning member (claim 6).

With the above configuration, packing in the wrong direction is prevented, and workability is improved. Furthermore, it leads to shortening of the time for the packing operation.
