BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a development view of a corrugated board case 1 according to the present invention, which includes an upper surface 2, a lower surface 3, left and right side surfaces 4,
5, an adhesive piece 6 formed by horizontally extending the upper surface 2, upper outer flaps 7 and 7a on both sides of the upper surface 2, lower outer flaps 8 and 8a on both sides of the lower surface 3, and inner left sides on both sides of the left side surface 4. Inner right flaps 10 and 10 on both sides of the right side 5 and the flaps 9 and 9a
A fold curve indicated by an alternate long and short dash line in the drawing is formed between each of the constituent surfaces constituted by a.

The upper outer flaps 7 and 7a are provided with perforations 12 for forming extrusion holes in a U-shape, an inverted U-shape or the like from a folding curve 11 between the upper outer flap 7 and the upper surface 2. This perforation 12 does not necessarily have to be a finely broken line.
It is also possible to connect only one or two points in a dot shape. The same applies to perforations, which will be described later.

When the perforation 12 is inserted, the perforation 1
The corners of the inner left flaps 9 and 9a and the inner right flaps 10 and 10a, which come inside the perforation 12 forming portion during assembly, are removed to allow inward punching along 2 (removal) Part 12a).

The inner left flaps 9 and 9a and the inner right flaps 10 and 10a are provided with perforations 13 and 14 which vertically divide into two in FIG. Then, the opening forming sewing machine extending from the middle of the perforations 13 toward the upper surface 2 and extending from the middle of the perforations 14 to the outer end (the end on the upper surface side during assembly) in FIG. Eyes 15 and 16 are inserted respectively.

Generally, folding curves 17 are obliquely provided at both corners of the upper outer flaps 7, 7a. This curve 17
The triangular portion formed by putting in is a holding piece 23 at the time of unpacking work described later. In addition, the bending curves 17a are also similarly formed at both corners of the lower outer flaps 8 and 8a.
May be provided.

In order to assemble the above pattern, each folding curve may be mountain-folded (or valley-folded). The inner left flaps 9 and 9a and the inner right flaps 10 and 10a are respectively upper outer flaps 7 and 7a. And the lower outer flaps 8 and 8a, and the back surfaces of the upper outer flaps 7 and 7a and the lower outer flaps 8 and 8a are respectively the inner left flaps 9 and 9a and the inner right flaps 10 and 10a. The inside of the perforation forming perforations 15 and 16 existing in the upper half of the surface is glued, and the sticking piece 6 is glued to the upper part on the front side of the right side surface 5, and the assembling is completed.

Needless to say, the upper outer flaps 7 and 7a and the lower outer flaps 8 and 8a are lapped as follows.
This is performed after the PPC paper volume 25 is stored.

In that state, the inner left flaps 9, 9
The outer side 18 of a and the outer side 19 of the inner right flaps 10 and 10a are in a butted state, and the outer side 20 of the upper outer flaps 7 and 7a and the outer side 21 of the lower outer flaps 8 and 8a project. The combined state is obtained (see FIG. 2).

Unpacking for taking out the PPC sheet 25 can be performed by the same operation from both the outer flaps 7 and 8 side and the outer flaps 7a and 8a side. The case of opening the unpacking operation from the side of the outer flaps 7 and 8 will be described. First, in unpacking, both corners of the upper outer flap 7 are bent along folding curves 17 to form a triangular gripping piece. 23 is formed (see FIG. 2).

Next, the gripping piece 23 is gripped and strongly pulled upward. Then, the inner left flap 9 and the inner flap 1
0 breaks from the perforations 13 and 14 in the horizontal direction to the perforations 15 and 16 in the vertical direction that are continuous with the perforations 13 and 14, respectively. As a result, the upper outer flap 7 is divided into the inner left flap 9 and the inner right flap 10. In the upper half portion, the inner half portions of the perforations 15 and 16 for forming the opening portions are integrally pulled up, so that the upper half portion of one side surface of the cardboard case 1 is opened.
The PPC sheet 25 can be taken out (see FIG. 3).

As a result of this breaking opening, the outer parts of the perforations 15, 16 of the inner left flap 9 and the inner right flap 10 remain as the remaining pieces 24 integrally on the left side surface 4 and the right side surface 5, respectively. The remaining piece 24 serves to maintain the strength of the entire case during handling, and when the opening is once opened and then re-sealed, the fractured side surfaces thereof are attached to the fractured side surfaces of the inner left and right flaps 9 and 10, and thus, the It serves to hold down the flap 7 from opening.

If the PPC sheet 25 is too tight to take out, the perforation 12 on the surface opposite to the opening is pressed with a finger to break it, and if it is pushed in as it is, the removing portion 12 is removed.
Since there is a, the fractured part abuts the PPC paper book 25,
Since the rear surface of the PC sheet book 25 is pushed and the front surface side protrudes from the opening surface (the state shown in FIG. 4), it is easy to pull it out. When resealing, the outer flap 7 may be returned to the original state.

Since the corrugated board case according to the present invention is provided with the paper ejection opening only in the upper half portion, the PPC in the lower half portion is provided.
The case 1 is turned over to take out the paper sheet 25. Alternatively, when the folding curve 17a is provided, it is folded from there to form a gripping piece, and the gripping piece is held to hold the outer flaps 8, 8
a is peeled from the lower half portions of the inner left and right flaps 9, 9a, 10, 10a to open the entire surface.

Although one embodiment of the corrugated cardboard case for PPC paper according to the present invention has been described above in detail, the present invention is not limited to the above embodiment, and various other design changes can be made. For example, the perforation in the above-described embodiment may have a structure such as a semi-thick cut line in addition to the above-described one.

[0020]

The present invention is as described above. According to the present invention, it is possible to form a gripping portion on the upper outer flap, and to pull up the gripping portion, and to pull the upper half portion at a stroke without requiring much force. Can be opened, and because the dust that separates from the main body such as broken pieces does not occur when unpacking, it can be folded and collected collectively, and since plastic tape is not used, problems in waste disposal Moreover, since re-sealing is possible and there is no opening or notch before opening, there is an effect that it is possible to meet the requirements of dust-proof and moisture-proof during storage.

In the second aspect of the invention, the PPC
At the time of taking out the sheet of paper, a rupture portion is formed which makes it possible to press the rear surface, so that there is an effect that the taking out becomes easy.
