Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a bookcase-type container such as a video cassette case.

<Prior art> Conventionally, as shown in FIG. 1, for this type of container, side plates 1 and 3 of approximately the same size are provided on both sides of a back plate 2 with a line ₀ interposed therebetween, and the upper and lower sides of one side plate 3 are Outer folding pieces 5, 5 are attached to the edges via the press line ₂ , and inner fold pieces 4, ₄ are attached to the upper and lower ends of the other side plate 1 via the press line 1.
are arranged in series, and the upper and lower ends of the back plate 2 are provided with pressed lines.
₁ , and the opposing ends of the inward folding piece 4 and the tongue piece 6 are provided with oblique sides 7 and 8 that abut each other. What is possible is known. However, in this conventional container, the second
As shown in the figure, the intersection A between the oblique sides 7 and 8 is
Since it is located near the center C of the width W of the pressed line ₀ , when assembled, there is a gap between the oblique side 8 of the tongue piece 6 and the oblique side 7 of the inner folding piece 4, as shown in FIG. A gap 9 is created.

Therefore, dust or the like may enter the container from the outside through the gap 9, staining the package such as a video cassette case, and degrading the quality.
It also has the disadvantage of spoiling the appearance.

<Problems to be solved by the invention> The present invention solves the above-mentioned problems of the prior art, eliminates gaps during box manufacturing, prevents dust from entering, and prevents contamination of packaged items such as video cassette cases. It is an object of the present invention to provide a bookcase type container that does not deteriorate quality or damage appearance.

<Means for solving the problem> The present invention was conceived in view of the above points, and is a container that can be assembled from a single piece of material, with side plates of approximately the same size attached to both sides of the back plate. , with outer folding pieces connected to the upper and lower ends of one side plate, inner folding pieces connected to the upper and lower ends of the other side plate, and tongue pieces connected to the upper and lower ends of the back plate. Opposite ends of the inner folding piece and the tongue piece are respectively provided with oblique sides that abut each other, and the intersection of these oblique sides is the intersection between the side plate and the back plate, the inner folding piece and the tongue piece. It is located 0.2 to 0.5 mm outward from the widthwise center of the pressed line that is the boundary between be.

<Function> The present invention has the above-mentioned structure, and the intersection of the opposing hypotenuses of the inner folding piece and the tongue piece is the boundary between the side plate and the back plate, and the inner folding piece and the tongue piece. Since it is located 0.2 to 0.5 mm outward from the center in the width direction, there is no gap at the intersection of the oblique sides, and they abut accurately.

<Example> Hereinafter, a detailed description will be given based on embodiments shown in the drawings.

In the present invention, the shape of the blank is basically the same as that in the prior art, so it will be explained based on FIG. 1 using the same numbers.

First, the present invention is a bookcase-type container assembled from a material made of paper laminated with thermoplastic synthetic resin such as polyethylene on both sides, or a flexible and rigid thermoplastic synthetic resin sheet such as polypropylene. , side plate 1 of almost the same size,
3 are provided on both sides of the back plate 2 via a press line ₀ , outer folding pieces _5, 5 are provided at the top and bottom ends of one side plate 3 via a press line 2, and press lines are provided at the top and bottom ends of the other side plate 1. ₁ , and tongue pieces 6, 6 are connected to the upper and lower ends of the back plate 2 through a press line ₁ . Opposite sides 7 and 8 are provided at opposing ends of the piece 6, respectively, and as shown in _FIG . It is a bookcase type container, which is characterized by being shifted outward by 0.2 to 0.5 mm from the center C, and is made by folding an inner folding piece 4 and a tongue piece 6, and then folding and fixing an outer folding piece 5 thereon.

Note that the shape of the blank is not limited to that shown in FIG. 1, and it goes without saying that it may be any shape as long as it has oblique sides 7 and 8 that abut the inner folding piece 4 and the tongue piece 6.

<Effects of the invention> Since the invention has the above structure,
As shown in FIG. 5, the tongue piece 6 and the oblique side parts 7 and 8 of the inner folding piece 4 abut each other accurately without creating a gap, preventing the infiltration of dust etc. as in the conventional case. There is no need to worry about this, and the container has an excellent protective function and appearance.
