DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for packing, for example, electric equipment.

[0002]

2. Description of the Related Art FIG. 7 is a perspective view showing an example of a conventional container. The container 10 includes, for example, a carton (box) 11 for storing items such as electric devices, and a carton 11.
And two cushions (buffers) 12 which are arranged on both sides of the bottom portion of the housing and which support and buffer the stored items. The carton 11 is formed in a rectangular parallelepiped shape by, for example, a cardboard material. The size of the carton 11 is made slightly larger than the size of the electric equipment to be stored.

The cushion 12 is formed, for example, of a styrofoam material into a prismatic shape. The length 1 of the cushion 12 is made to be the same as the width L of the carton 11. A wedge-shaped projection 12 a is provided on one end surface of the cushion 12. When the cushion 12 is inserted into the carton 11 in the direction of the arrow shown in the drawing, the projection 12a is compressed on the inner surface of the carton 11 and serves to fix the cushion 12 at the bottom of the carton 11 at the position indicated by the cross line shown in the figure. .

[0004] By the way, from the viewpoint of environmental protection in recent years, containers using less cushion material have been developed. FIG. 8 is a perspective view showing a conventional example of such a container. The container 20 includes, for example, a carton (box body) 21 for storing a storage item such as an electric device and four corner portions at the bottom of the carton 21 for mounting and buffering the storage item. And a cushion (buffer) 22.

The carton 21 is formed of, for example, a cardboard material in a rectangular parallelepiped shape. The size of the carton 21 is made slightly larger than the size of the electric equipment to be stored. The cushion 22 is formed in a rectangular parallelepiped shape using, for example, a polystyrene foam material. The cushion 22 may be of a size that can be arranged at the four corners at the bottom of the carton 21. For example, the cushion 22 is formed to have a size obtained by dividing the end of the cushion 12 shown in FIG. . Therefore, according to such a cushion 22, the amount of cushion material used can be reduced by the amount corresponding to the central portion of the cushion 12 shown in FIG.

However, as in the case of the cushion 12 shown in FIG. 7, the projection 12a cannot be provided and fixed to the bottom of the carton 11. Therefore, a rectangular parallelepiped projection 22a is provided on the bottom surface of the cushion 22.
The bottom of the carton 21 is provided with a rectangular hole 21a into which the projection 22a fits when the cushion 22 is arranged. The projection 22a is inserted into the hole 21a when the cushion 22 is inserted into the carton 21 in the direction indicated by an arrow, and serves to fix the cushion 22 at a position indicated by a cross line on the bottom of the carton 21.

[0007]

As described above, in the latter container 20, the amount of cushion material used can be reduced. However, by inserting the projection 22a of the cushion 22 into the hole 21a of the carton 21,
Is simply fixed to the carton 21 so that the carton 2
When an impact is applied to 1 or the carton 21 is inverted, the projection 22a may come off from the hole 21a, and the usability is poor.

The present invention has been made in view of the above circumstances, and provides a container that can reduce the amount of material used for a buffer and that can securely fix the buffer in a box. The purpose is to:

[0009]

SUMMARY OF THE INVENTION The object of the present invention is to provide a container for accommodating stored items, and a box disposed at each corner of the bottom of the box to support the stored items. A convex portion provided on a bottom portion of the buffer portion, and a concave portion in which the convex portion can be fitted is provided on a bottom portion of the box body. The distance between the outer surface and the other outer surface of the buffer body on the opposite side is determined by the distance between the inner surface of the concave portion that contacts the one outer surface and the inner surface of the box that contacts the other outer surface. This is achieved by making it larger.

According to the above configuration, the convex portion and the concave portion are formed so that the position of the convex portion of the buffer and the position of the concave portion of the box when the buffer is fixed to the box are shifted. In order to fit the convex portion into the concave portion, it is necessary to push the buffer into the box. For this reason, even if the buffer is divided into four parts, the buffer and the box are held together by the elastic force, so that the buffer can be firmly fixed to the box.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Note that the embodiments described below are preferred specific examples of the present invention,
Although various technically preferable limits are given, the scope of the present invention is not limited to these modes unless otherwise specified in the following description.

FIG. 1 is a perspective view showing an embodiment of the container of the present invention. The container 30 includes, for example, a carton (box body) 31 for storing a storage item such as an electric device, and four corner portions at the bottom of the carton 31 for mounting and buffering the storage item. And a cushion (buffer) 32. The carton 31 is formed in a rectangular parallelepiped shape by, for example, a cardboard material. The size of this carton 31 is
It is made to be slightly larger than the size of the electrical equipment etc. to be stored.

The cushion 32 is formed in a rectangular parallelepiped shape by, for example, a polystyrene foam material. This cushion 32
Is made to be substantially the same size as the cushion 22 shown in FIG. 8, for example. According to such a cushion 32, as in the cushion 22 shown in FIG. 8, the amount of cushion material used can be reduced.

Further, a rectangular parallelepiped convex portion 32a is provided at one corner of the bottom surface of the cushion 32.
On the bottom surface of the carton 31, there is provided a substantially L-shaped concave portion 31a into which the convex portion 32a fits when the cushion 32 is arranged. The cushion 32 having the convex portion 32a and the carton 31 having the concave portion 31a are shown in FIG.
As shown in FIG.
One outer surface 32b on the side a and the other outer surface 32c on the opposite side
Is smaller than the distance d, the concave portion 31 in contact with the outer surface 32b.
The distance d is larger than the distance D between the inner side surface 31b of the carton 31 and the inner side surface 31c of the carton 31 which contacts the other outer side surface 32c.

That is, the other outer surface 32c of the cushion 32 and the outer surface 32d perpendicular to the outer surface 32c are connected to the inner surface 3 of the carton 31.
Even if the cushion 32 is inserted in the direction indicated by the arrow in the drawing in a state where the cushion 32 is in contact with the inner surface 1d and the inner surface 31d perpendicular thereto, the projections 32a and the depressions 31a are displaced by Δd (= d−D), so they are fitted. I am not able to do it. In order to fit the projection 32a and the recess 31a, as shown in FIG. 2B, the cushion 32 is once inclined toward the projection 32a, and the outer surface 32b of the projection 32a is turned into the inner surface 31b of the recess 31a. Contact.

The projection 32a is fitted into the recess 31a by rotating the cushion 32 in the direction of the arrow shown in the figure around the contact portion 30a. As a result, the cushion 32 is slightly compressed, and the carton 31 is held in a slightly stretched state, that is, in a state where mutual restoring force is built in. As shown in FIG.
1 can be firmly fixed to the bottom.

When the shape of the concave portion 31a is a rectangular shape corresponding to the shape of the convex portion 32a, the convex portion 32a
When fitted in the recess 32, the recess 31a may be torn by the restoring force of the cushion 32 described above. For this reason, the shape of the concave portion 31a is substantially L-shaped, and the concave portion 31a is deformed at a portion where the convex portion 32a is not fitted to prevent the concave portion 31a from being torn.
Therefore, as shown in the developed view of the carton 31 in FIG. 4, a portion 31a of the concave portion 31a where the convex portion 32a is not fitted.
a is parallel to the inner side surface 31b of the concave portion 31a,
It is desirable to provide the cardboard material at right angles to the direction of the eye 31e.

When the container 30 is used repeatedly, the restoring force of the cushion 32 described above causes the protrusion 3
2a may be broken. In order to cope with such a case, as shown in FIG. 5, a part (cross-line part) 31f of the bottom of the carton 31 forming the recess 31a is formed in advance so as to be able to rise, and FIG. As shown in
The rising portion (cross line portion) 31f is cushion 3
The cushion 32 may be firmly fixed to the bottom of the carton 31 by being brought into contact with the outer surface 32b on the side of the convex portion 32a in FIG.

That is, as shown in FIG. 5, two cuts (thick lines in the drawing) 31g and 31h are made in advance in a direction orthogonal to the inner side surface 31b of the concave portion 31a.
Form f. Then, as shown in FIG. 6, the cushion 32 is pressed down by the rising portion 31f by bending the cutting incision at a broken line (dotted line in the drawing) 31i. Thereby, even if the convex portion 32a is broken, the container 30
Can be used, so that the life of the container 30 can be extended.

In the above embodiment, the cushion 3
Although the formation position of the second convex portion 32a is a corner portion, the present invention is not limited to this, and the same effect can be obtained by forming one or a plurality of portions at an arbitrary position on the bottom surface of the cushion 32. it can. Also, the projection 32a of the cushion 32
Is a rectangular parallelepiped shape, but the shape is not limited to this, and the same effect can be obtained by forming the cushion 32 and the carton 31 into an arbitrary shape as long as the cushion 32 and the carton 31 can be locked.

[0021]

As described above, according to the present invention,
The amount of material used for the buffer can be reduced,
The buffer can be securely fixed in the box.
