The rising pieces 23 and 24 are formed by the outer bending lines 15 and 16, respectively, and the second rising pieces 23 and 24 include the outer bending lines 15 and 16 between the second rising pieces 23 and 24 and the lid 5, respectively. Perforation line 2 inclined from both ends of 16 to the outer bending line
6, 27, 28, 29 are formed respectively, and the first and second joint pieces 19, 20, 21, 22
and the first and second rising pieces 17, 18, 23, 24
and are configured such that they can be fixed to each other with the first and second joint pieces facing inside.

<Embodiment> FIG. 1 is a developed view of an embodiment of the present invention, and FIG. 2 is a perspective view showing the embodiment of FIG. 1 in a semi-assembled state. The packaging container 33 is made of cardboard or the like, and includes a bottom plate 3, first and second side plates 2, 4 connected to the bottom plate 3, a lid 5 connected to the second side plate 4, first and second joining pieces 19, 20, 21, 22 and first and second rising pieces 17, 18, 23, 24. The first side plate 2, the bottom plate 3, the second side plate 4, and the lid 5 are arranged in a straight line with a straight outer bending line 6,
7 and 8 in succession. First side plate 2
First joint pieces 19 and 20 are formed at both ends of the joint member 19 and 20, which are opposed to each other by outer bending lines 9 and 10.
The outer bending line 34 forms the lid joining piece 25. At both ends of the second side plate 4 there is an outer bending line 1.
1 and 12, the second joining piece 2 faces each other
1 and 22 are formed. At both ends of the bottom plate 3, first rising pieces 17 and 18 are formed which face each other along outer bending lines 13 and 14. Also, at both ends of the lid 5, second upright pieces 23 and 24 are formed by outward bending lines 15 and 16 to face each other.

The second rising pieces 23, 24 have perforated lines 26, 27 at both ends thereof, which pass through both ends of the outer bending lines 15, 16 and have an inclination θ (for example, 45 degrees) with respect to the outer bending lines. , 28, 29 are formed, and these sewing machine cut lines 26, 27, 28,
A non-sealed portion 23 is provided on the inner side divided by 29.
a, 24a has seal parts A, B, C, on the outside thereof.
D and are provided respectively.

The first rising pieces 17 and 18 of the bottom plate 3 are provided with seal portions E, F, G, and H at both ends, respectively.
At both ends of the first joint pieces 19 and 20, there are seal parts A' and B corresponding to the seal parts A and B of the second rising piece 23, respectively.
B′ and the seal portion G of the first rising piece 17, 18,
Sealing portions G′ and H′ corresponding to H are provided, and a second
A second rising piece 23 is provided at both ends of the joining pieces 21 and 22.
Seal parts C', D' corresponding to seal parts C, D',
Seal portions E' and F' corresponding to the seal portions E and F of the first rising pieces 17 and 18 are provided.

Punched holes 30 for joining are provided at both ends of the lid joining piece 25.
The lid 5 is provided with a joining punching hole 31 that is paired with the joining punching hole 30.

When assembling the packaging container 33, after placing the stored items on the base 3, the first and second side plates 2, 4 are assembled.
along the outer bending lines 6 and 7 so as to be perpendicular to the base 3 and facing each other, and the lid joint piece 25 is bent along the outer bending line 34 to the first side plate 2. Fold perpendicularly to the
Fold the lid 5 perpendicularly to the second side plate 4 along the outer bending line 8, stack it on the lid joint piece 25, and insert the joining punch holes 30, 31 provided in the lid 5 and the lid joint piece. By inserting and fixing the PP joint 32 shown in FIG. 6, the stored articles are surrounded.

Next, the first and second joint pieces 19, 20, 2
1 and 22 along the outer bending lines 9, 10, 11, and 12 in the vertical direction with respect to the first and second side plates 2 and 4, the first and second rising pieces 1
7, 18, 23, 24 to the outside bend line 13, 1
4, 15, and 16 in a direction perpendicular to the bottom plate 3 and the lid 5, and so as to face each other. After that, the first and second joint pieces 19, 2
0, 21, 22 seal parts A', B', C', D',
E', F', G', H' are the first and second rising pieces 17,
Each seal part A, B, C, D of 18, 23, 24,
Attach E, F, G, and H to each other with adhesive. This adhesive is preferably a hot melt adhesive, for example. Note that a large stapler may be used instead of the adhesive. In this way, as shown in FIG.
A side surface surrounded by the side plates 2 and 4 and the lid 3 and formed by the first joint piece 19, the second joint piece 21, the first rising piece 17 and the second rising piece 23;
Joint piece 20, second joint piece 22, and first rising piece 18
and the side surface formed by the second rising piece 24 prevents stored articles from falling out.

After assembly, when unpacking, please
Non-sealed portions 23a, 24a of rising pieces 23, 24
along sewing machine cut lines 26, 27, 28, 29,
By cutting and removing the PP joint,
The state will be as shown in Figure 4.

Next, in order to reseal the package, as shown in FIG.
Similarly, the non-sealed portions 23 of the second rising pieces 23, 24 are placed in a state where the ends overlapping the second joint pieces 21, 22 of a are applied to the outer surfaces of the joint pieces 21, 22.
Insert the ends of a and 24a that overlap the first joint pieces 19 and 20 into the inner surfaces of the joint pieces 19 and 20, and
By removing the joint 32, the package can be resealed.

<Effects of the Invention> According to the present invention, the area of the overlapping portion of the cardboard is small and the developed view is a nearly rectangular strip, so the amount of cardboard used can be reduced. In addition, since the stored items are wrapped in a band-shaped corrugated sheet and pasted on both sides,
Packing work can be easily automated on the production line, and since openings are formed on two of the six sides of the case, it is easier to take out stored items.
Furthermore, after sealing, there is no need to use adhesive tape, etc.
It is convenient because it can be resealed simply by inserting the unsealed part into the gap in the container.
