The packaging box 20 is formed, for example, by cutting corrugated cardboard or the like into an appropriately expanded shape and assembling it.

FIG. 3 shows an example of how cardboard is developed for manufacturing the packaging box 20. In addition, the development form of the corrugated board for manufacturing the packaging box 20 is not limited to this example.

In this expanded form, the side faces 26f, 2 are formed.
Four plate-like side members 2 corresponding to 7f, 28f, and 29f
6, 27, 28, 29. These plate-shaped side members 26, 27, 28, 29 are the plate-shaped side member 27, the plate-shaped side member 28, the plate-shaped side member 26, and the plate-shaped side member 29.
In this order, they are integrally formed in the form of being arranged in series in this order to form the integrally formed body 25a.

Further, a joining piece 25p is formed on one end edge of the series integrally formed body 25a. Then, the joining piece 25p is superposed on the other end edge portion of the series-integrally-formed body 25a, and joined by using a known stopper, or the like,
The series-integrated body 25a is formed into a trapezoidal cylinder.

The upper surface portion 21 has a first outer surface 21f.
It has a pair of upper surface part division plate-like bodies 22d which are divided by the one oblique side 21fc side and the other oblique side 21fc side.
Each of the upper surface portion divided plate-shaped bodies 22d has plate-shaped side surface members 28, 29 of the series integrally formed body 25a via the hypotenuse 21fc.

Then, regarding the development form shown in FIG.
The serially formed body 25a is formed into a trapezoidal cylinder, and the lower surface parting plate member 24d and the auxiliary plate members 24sa, 24s are folded inwardly to form the lower surface part 23 and the upper surface parting plate member. When the body 22d and the auxiliary plate-shaped bodies 22sa and 22s are folded inwardly to form the upper surface portion 21, the packaging box 20 having the shape shown in FIG. 1 is completed.

When the CRT display 10 is packed in the packing box 20, as shown in FIG. 2, a cushioning material 15 such as expanded polystyrene is usually interposed between the outer shape of the CRT display 10 and the inner surface of the packing box 20. Thus, a space having a predetermined size is formed between the outer surface of the packaging box 20 and the outer surface of the CRT display 10. This prevents the impact from being directly applied to the CRT display 10 when an external impact is applied to the packaging box 20.

The packing box 20 constructed in this way is shown in FIG.

b) The four packaging boxes 20 can be arranged side by side in a width dimension of ÷ 2.

Incidentally, the conventional packing box 20 shown in FIG.
Since 1 has the same width dimension a as the above a evenly before and after it, a width dimension of a × 4 is required to arrange four packaging boxes side by side. It is necessary to have a width dimension larger than that of the four packaging boxes 20 according to the above.

Therefore, in this packaging box 20, the packaging boxes can be stacked with a relatively high density.

Moreover, in this packing box 20, the packing box 20
Since the gap between the inner surface of the cushioning material and the outer surface of the CRT display 10 is almost the same, the amount of the cushioning material 15 used can be suppressed to the necessary minimum, and the resource saving and cost reduction of the cushioning material 15 are possible.

Furthermore, since the upper surface portion 21, the lower surface portion 23, and the plate-shaped side surface member 27 can be made smaller than the corresponding portions of the conventional packaging box 201, the development area of the packaging box 20 can be made small, and corrugated paper, etc. It is possible to save resources and reduce the cost of packaging materials.

In this packing box 30, the packing work and the taking-out work can be easily performed without lifting the heavy CRT display 10 high.

Note that only one of the upper surface portion 31 and the lower surface portion 33 may be formed separately from the side surface portion 35.

Third Embodiment Next, a packing box according to Embodiment 3 of the present invention will be described. The same components as those in the first embodiment will be designated by the same reference numerals, and the description thereof will be omitted. Differences from the same will be mainly described.

As shown in FIGS. 7 (a) and 7 (b),
In the packaging box 40, the upper surface portion 41 and the lower surface portion 43 are formed separately from the side surface portion 45. Then, the upper surface portion 41
The lower surface portion 43 is fixed to the side surface portion 45 by using a known fastener or a packing band or the like.

The upper surface portion 41 is similar to the upper surface portion 21 in that

The length dimension), the width dimension c of the plate-shaped side member 29 (the length dimension of the trapezoidal oblique side 21fc), and the plate-shaped side member 26.
And the sum of the width dimension a (the length dimension of the long side 21fa of the trapezoidal shape) are different. Therefore, the serially formed integrally formed body 25a formed in a tubular shape cannot be properly divided into two and cannot be folded in a plane shape.

The fourth embodiment is intended to improve this point.

In the description of the fourth embodiment,
Constituent elements similar to those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. Differences from the same will be mainly described.

FIG. 10 is a perspective view of the packaging box 50 according to the fourth embodiment, and FIG. 11 shows a developed form of the packaging box 50.

In this packing box 50, the side line portion 25 extends along a direction substantially perpendicular to the upper face portion 21 and the lower face portion 23, and is a guideline for a fold line when the side face portion 25 is folded in a plane. A reference line 55L is provided.

It is possible to divide into 29 spaces.

Here, the dividing line portion 60L is formed on one side of the plate-like side surface member 26 so as to extend in the vertical direction. As shown in FIG. 15, the dividing line portion 60L is preferably formed at the center position as much as possible in the longitudinal direction of the series integrally formed body 25a. This is because if the pieces after division are as large as possible, the subsequent discarding work will be easier.

Further, as shown in FIG. 14, the dividing line portion 60L is made of a resin or the like having excellent tensile strength to the extent that the constituent member can be divided inside the corrugated paper or the like which is a constituent member of the side surface portion 25. The tear tape 60T is embedded. Then, when the end portion of the tear tape 60T is pulled, the tear tape 60T divides the plate-shaped side surface member 26 into cut shapes, whereby the side surface portion 25 is divided vertically. .

According to the packaging box 60 thus constructed, the plate-shaped side member 26 can be divided along the dividing line portion 60L. Accordingly, the side surface portion 25 can be easily disassembled and easily folded into a flat shape. Further, the CRT display can be easily taken out from the packaging box 60.
