[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box for storing flat articles in a stacked state.

[0002]

2. Description of the Related Art As a packaging box of this kind,
There is one shown in FIG. This packaging box has a top plate 5
1, flaps 54 are continuously provided at both ends of a rectangular cylinder formed by a bottom plate 52 and a pair of side plates 53 facing each other;
By folding the flap 54, the packaging box is closed.

[0003] At one end, a cut tape 55 is provided over the entire circumference of the rectangular cylinder, as shown in FIG.
As shown in FIG. 7, the cut tape 55 cuts off the end and takes out the stored article.

By the way, in such a packaging box,
The stored articles can be easily taken out, but after opening, the packaging box is separated into two parts, so it is troublesome to attach and detach the cut-off lid part. In addition, when the lid is discarded, a part of the stored article is exposed, and the appearance of the stored article is poor, and the stored article may be stained or damaged.

An object of the present invention is to provide a packaging box which can be easily taken out and can be resealed after opening.

[0006]

In order to solve the above-mentioned problems, the present invention is to form a rectangular cylinder by a top plate 14, a bottom plate 12 and a pair of side plates 11 and 13 facing each other. , 13 are provided with inner flaps 21, 23 via fold lines 35, 37, and outer flaps 24, 22 which are not overlapped with each other are provided at both ends of the top plate 14 and the bottom plate 12. The side plate 13 is provided with rupture means extending from one inner flap 23 to the other inner flap 23 along the leading edge of the outer flaps 24 and 22 folded on the inner flap 23. 1
2 is provided with fold lines 14a, 12a from one end to the other end, and discontinuous cuts 24a, 22 from the ends of the fold lines 14a, 12a to the tips of the outer flaps 24, 22.
a, and the inner flaps 2 adjacent to both sides of the outer flaps 24 and 22 at the cuts 24a and 22a, respectively.
Thus, a cardboard packaging box made of cardboard or the like, which is fixed to the first and the second 23, is provided.

[0007]

In the packaging box constructed as described above, flat articles are accommodated so as to be stacked on the bottom plate 12, and then the outer flaps 24, 22 and the inner flaps 21, 23 are fixedly packed.

[0008] When taking out the stored articles, the side plate 11 without the rupture means is placed on the lower side, and the side plate 13 and the inner flap 23 connected thereto are cut open by the rupture means, and the outer flaps 24, 22 are cut. When cut open by 24a, 22a, the upper part of the packaging box becomes crease lines 14a, 12
It completely opens outward from the center a, and all the articles appear in a protruding state.

[0009] When only a part of the stored articles is to be taken out, the upper part of the opened packaging box is closed and then resealed.

[0010]

Embodiments will be described below with reference to the drawings. The packaging box shown in FIG. 1 is assembled from the cardboard blank shown in FIG.

The blank comprises a side plate 11 and a bottom plate 1
2, the side plate 13, the top plate 14, and the seam allowance 15 are sequentially connected via fold lines 31, 32, 33, 34,
Inner flaps 21 and 23 are provided at both end edges of the side plates 11 and 13 via fold lines 35 and 37, and outer flaps are provided at both end edges of the top plate 14 and the bottom plate 12 via fold lines 38 and 36. Flaps 24 and 22 are respectively provided continuously.

The inner flaps 21 and 23 have a length that does not overlap each other when bent, and the outer flaps 22 and 24 have a length that abuts each other when bent.

A cut tape 13a extending from the front end of one inner flap 23 to the front end of the other inner flap 23 is attached to the rear surface of the side plate 13 at the center in the width direction. A tab 13b is formed at the center by a cut 13b.

A fold line 14a extending from one end to the other end is provided at the center of the top plate 14 and the bottom plate 12 in the width direction.
12a is provided, and the outer flaps 24 and 22
Discontinuous cuts 24a and 22a are formed which are inclined toward the side plate 13 from both ends of the fold lines 14a and 12a toward the ends. In addition, fold lines 24b and 22b extending from the side edges on the side plate 13 side to the cuts 24a and 22a are provided at the distal ends of the outer flaps 24 and 22, respectively.

In the blank constructed as described above, a glue allowance 15 is adhered to the side plate 11 to form a rectangular cylinder, and the flat articles A are stacked and stored on the bottom plate 12, and then the outer flaps are formed. When the both sides of the cuts 24 and 22 at the cuts 24a and 22a are fixed to the adjacent inner flaps 21 and 23, respectively, the packing state as shown in FIG. 1 is obtained.

When taking out the stored articles, as shown in FIG. 3, the packaging box is placed with the side plate 11 down, and the side plate 13 and the inner flap 23 are broken by the cut tape 13a. At this time, the fold line 2 of the outer flaps 24 and 22
The distal end side is bent outward from 4a, 22a to form a passage for the cut tape 13a, and the inner flap 23 can be easily broken.

Then, put a finger on the broken portion of the side plate 13 and
When the upper portions of the packaging boxes are rotated outward about the fold lines 14a and 12a, the cuts 24a and 22a are cut open, and the packaging box is opened as shown in FIG.
In this state, all the stored articles A project vertically and are very easy to take out.

When a part of the stored article A is taken out and stored as it is, it can be resealed by closing the opened upper part of the packaging box. At this time, the inner flaps 23 protruding from the upper portions of the cut out outer flaps 24 and 22 are sandwiched between the lower outer flaps 24 and 22 and the article A as shown in FIG. The reseal state is reliably maintained by the frictional force.

By inclining the cuts 24a and 22a, the top plate 14 and the bottom plate 12 are hardly bent by the fold lines 14a and 12a when the top plate 14 and the bottom plate 12 are raised by automatic packing. There is also an advantage.

[0020]

As described above, in the packaging box of the present invention, the rupture means is provided on one side plate 13 and the inner flap 23 connected thereto, and the fold line 14 is provided on the top plate 14 and the bottom plate 12.
a, 12a and the discontinuous cuts 24a, 22a provided in the outer flaps 24, 22 connected to each other. When the top of the packaging box is cut open by the breaking means and the cuts 24a and 22a, all the stored flat articles appear in a protruding state, and the articles can be easily taken out.

When a part of an article is taken out and stored, it can be easily resealed simply by closing the upper part of the opened packaging box, so that the inside article is not stained or damaged. Appearance is also good.
