Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular parallelepiped thin paper box that can be displayed in a stand-alone state at the time of sale and can be stored in a stand-alone state when used.

[0002]

2. Description of the Related Art Conventionally, many products in which contents such as foods contained in a bag are contained in a rectangular parallelepiped thin paper box are commercially available. This type of paper box allows the manufacturer to fill the paper box with contents such as food stored in various types of bags with one line, and these paper boxes filled with the contents etc. A single line is sufficient for the integrated packaging, and a cardboard box, etc. for integrated packaging can also be of a single size, and it is possible to grasp the number of items loaded on trucks, etc. Therefore, it is a very useful paper box.

However, since none of the paper boxes of this type can be displayed independently by themselves at the time of sale, they must be displayed flatly or in a column, and in the case of There was a problem that it was not effective for appealing to people, and in the case of, the column state was disturbed every time it was purchased, and the display state was bad. Also, it doesn't matter if the buyer uses up all the contents at once,
When it is used multiple times, it cannot be stored in a self-supporting state, so it has no presence, and sometimes forgets the paper box with unused contents and buys a new one. There was waste.

[0004]

And the creases 3 connected to the inclined plate 92.
A movable plate 93 which is narrower than the front plate 2 connected through
And the engaging projections 8 connected to each other through folding lines 35 provided with locking notches 11 on opposite sides of the movable plate 93.
The score line 1 that is made of
0a and 10b are two cuts parallel to the creases 21 and 22, and the end II of the crease line 10a and 10b on the crease 32 side is on the front plate 2 through the creases 32 and 33. The front when forming a triangular cross section in which the included angle between the front plate 2 or the rear plate 4 and the bottom plate 91 is a right angle or an obtuse angle close to a right angle by the bottom face forming plate 91 and the inclined plate 92 that are connected to each other The position of the apex of the face plate 2 or the back plate 4 and the inclined plate 92, and the cut lines 10a, 1
The other end III of 0b is the crease 32 to the crease 2
1, a position substantially equal to the length of the engaging projection 8 connected to the bottom plate 91, the inclined plate 92, and the movable plate 93 parallel to the top plate 6 side edge. It is the same as the paper box A of the first embodiment except that it is formed as described above.

As a method of assembling the paper box B shown in FIG. 7 from the blank plate B'shown in FIG. 9, first, the back surface of the side plate 1 and the adhesive margin piece 5 are adhered to each other, and the crease 21,
Each face plate is raised at 22, 23, and 24 to form a tubular body having a rectangular cross section, and then the bottom face forming plate 91, the inclined plate 92, and the movable plate 93 are folded back to the outside by the creases 32 and the engagement is performed. The cut line 10a in which the projecting piece 8 is formed on the front plate 2,
10b, and then fold the folding flaps 50 of the side plates 1 and 2 on the lower part of the front plate 2 (on the upper side of FIG. 9) into the inside respectively, and then fold the bottom plate 7 and the inserting flap 70 inside. Then, the lower opening is sealed, then the contents are stored from the upper opening, and then the hanging portion 13 is folded inward by the crease 37 and the upper portion of the front plate 2 (upper FIG. 9). By folding the folding flaps 50 of the side plates 1 and 2 inward and then folding the top plate 6 and the insertion flap 60 inward and sealing the upper opening, the paper box B shown in FIG. 7 can be obtained. it can.

In order to display or store the paper box B in a self-supporting manner, the movable plate 93 is slid downward (upper FIG. 7) from the state shown in FIG. As shown in FIG. 10, by locking the locking notch 11 (see FIG. 9) provided in the fold line 35 at the end II (see FIG. 9) of the fold line 32 side of each of 10a and 10b, as shown in FIG. The support portion 9 including the bottom surface forming plate 91, the inclined plate 92, and the movable plate 93 having the engaging projections 8 is formed, so that the paper box B can stand on its own.

In the embodiment, the supporting portion 9 used when the paper boxes A and B are independently displayed and stored has a triangular cross section. However, the supporting portion 9 is not limited to this. All the items that do not deviate from the gist of the present invention are included, and may be configured to have a quadrangular cross section, for example. Although not shown, the inclined plate 92 is provided with, for example, one or a plurality of U-shaped cuts or the like so that a measuring tool such as a spoon can be inserted when the tilted plate 92 is stored in a self-supporting manner. It's okay. Further, in the embodiment, the structure in which the hanging portion 13 having the hanging notch 12 and the zipper 14 are provided is shown, but these may be provided as necessary.
