DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an industrial technical field of a cardboard box for storing articles such as electronic components, and more particularly to a free-spaced cardboard box whose internal volume can be freely changed.

[0002]

2. Description of the Related Art Cardboard boxes are widely used in various industries such as electronic components such as quartz oscillators for storing, packing and transporting articles. In recent years, there has been a demand for a cardboard box whose internal volume can be varied according to the number of quartz resonators and which can be easily managed.

FIG. 4 is a diagram of a cardboard box for explaining a conventional example. The cardboard box 1 is made of a single sheet of corrugated paper (not shown) having a wavy portion in the middle,
This can be folded and assembled. After assembly, box body 2
The other end (lower surface) is a closed surface, and the one end (upper surface) is an open surface. Tongue pieces 3 serving as lids extend from four sides on one end side of the box body 2.

[0004] Then, for example, corner pads (not shown) are arranged at the four corners of the bottom, and a plurality of small boxes 4 containing crystal oscillators or the like are stacked and stored in the box body 2 (fifth).
Figure). In the gap between the inner periphery of the box body 2 and the small box 4, a cushioning material (not shown) such as styrene foam made of small pieces is embedded. The quartz oscillator is held, for example, by a transfer embossed tape and wound around a reel (not shown). One reel holds, for example, thousands or more crystal oscillators.

[0005] In such a case, cardboard boxes 1 of different sizes are prepared (assorted) in accordance with the number of ordered quartz resonators (the number of small boxes 4). For example, one small box 4
Three types of cardboard boxes 1 for 10 and 10 pieces are prepared.
If the number of small boxes 4 in the order number is, for example, six, 10
The individual cardboard boxes 1 were sequentially stacked, and the above-described cushioning material 5 was buried and stored in the upper space (the sixth space).
Figure).

[0006]

[Problems to be Solved by the Invention]
However, if the number of small boxes 4 and the size of the cardboard box 1 do not match, the cushioning material 5
Uselessly and increase the volume at the same time. And since the buffer material 5 is usually made of resin such as styrene foam,
It is not suitable for the global environment. In addition, making the volume larger than necessary increases the transportation cost and also causes an increase in cost.

[0007] In recent years, many users use quartz oscillators, and the number of orders varies widely. From this, it is conceivable to prepare the cardboard boxes 1 according to the number of the small boxes 4. However, in this case, the number of types of the cardboard boxes 1 is too large, which is complicated and maintenance is difficult. And it goes against standardization.

(Object of the Invention) An object of the present invention is to provide a cardboard box of free capacity which promotes standardization, facilitates management, and improves productivity.

[0009]

According to the present invention, a first horizontal cut is formed on the outer periphery of the box body from the other end side, which is the closed surface of the box body, toward the opening surface on one end side. A basic solution is to provide a second cut at a vertical ridge line from the front to the closed surface.

[0010]

According to the present invention, a first cut in the horizontal direction is provided on the outer periphery of the box main body from the opening surface on one end side, and a second cut is formed on the ridge portion, so that the first cut is cut or bent. The volume of the box body is varied by cutting the second cut. Hereinafter, an embodiment of the present invention will be described.

[0011]

1 and 2 are views for explaining an embodiment of the present invention. FIG. 1 is a view of a cardboard box, and FIG. 2 is an expanded view of the same. The same parts as those in the prior art are denoted by the same reference numerals, and description thereof will be omitted or simplified. The corrugated cardboard box 1 is formed by assembling a piece of corrugated paper as described above. The other end of the box body 2 is a closed surface, and a continuous tongue piece 3 serving as a lid is formed from the four sides of the open end. Extends. In this embodiment, a first cut 6 such as a perforation is formed on one piece of corrugated paper 1a forming the corrugated cardboard box 1 in the horizontal direction from the upper end side including the tongue piece 3 to the lower end side.
a is formed. Conversely, the first cuts 6a are formed in the horizontal direction at a predetermined distance from the closed surface and at regular intervals. In this case, however, the boundary between the tongue piece 3 and the box body 2 is a fold 6c. Then, a second cut 6b is formed at four ridges in the vertical direction from the opening surface to the closing surface.

In such a case, the height from the closed surface to the fold 6c of the tongue piece 3 is set to a normal height, for example, ten small boxes 4. If the order number of the small box 4 is 6, the second

Remove along A and adjust the length from the opening surface.

With such a configuration, the height can be set according to the number of small boxes 4. Therefore, as described above, the use of the unnecessary cushioning material 5 is minimized. In addition, the amount of resin such as styrene foam is reduced, which is good for the global environment. Further, the volume is not increased unnecessarily, the transportation cost is suppressed, and the cost is reduced. Since the product lineup of the cardboard boxes 1 (cardboard paper 1a) is reduced, management can be facilitated and standards can be standardized.

[0014]

In the above embodiment, the first cut 6a is also provided in the tongue piece 3 and the tip is cut off in accordance with the height. However, for example, the tongue pieces 3 facing each other may be overlapped during assembly.
The tongue piece 3 does not necessarily need the first cut. In addition, the first and second cuts 6 (ab) are provided on one end side as an opening surface, but may be provided from both end sides as shown in the plan view of FIG. 3, for example. In this case, since there is no direction, the assembling work is facilitated.

[0015]

According to the present invention, a first horizontal cut is formed on the outer periphery of the box body from the other end side, which is the closing surface of the box body, to the opening surface on one end side, and from the opening surface to the closing surface. Since the second cut is provided at the ridge portion in the vertical direction toward the head, it is possible to provide a freely movable cardboard box which promotes standardization, facilitates management, and improves productivity.
