BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case composed of one blank sheet.

[0002]

2. Description of the Related Art Conventionally, a corrugated cardboard packaging box includes:
There are various types, for example, types such as A-type and B-type are widely used as general-purpose products. These packaging boxes are generally assembled from one blank sheet to form a box, and are stored in a folded state before being used as a box.
That is, after fixing the joining margin provided at one end of the blank sheet to the side surface or the lug surface of the other end with glue or staples, etc., it is folded in two, and is appropriately assembled at the time of use, or in the box making process. It is supplied to form a packaging box. Further, as a packaging box having such a structure, there is a packaging box formed by connecting two blank sheets. This is a case formed for storing a long object, and is formed substantially in the same manner as described above, but a splice margin is provided for each of the two blank sheets. This is fixed to the side surface or the tab surface of another blank sheet. The reason why a box is formed using two blank sheets is that there is a limit to the size of a blank sheet that can be manufactured with a general corrugator machine, and a blank sheet is required to form a long case. Is necessary to be divided into two.

Here, as a conventional case for storing a long object, for example, as shown in FIG. 9A), a blank sheet having a lid surface 21, a side surface 22, and a tab surface 25, and a bottom surface 23, a side surface 2
4. There is a long case 20 formed by connecting blank sheets each having a tab surface 26 (FIG. 9B)]. These two blank sheets are provided with splices 27 on the side surfaces 22 and 24, respectively, and are fixed to the other tab surfaces 26 and 25 with staples 28, respectively.

[0004]

As described above, in the conventional packaging box, it is indispensable to fix the joint by stapling or the like when assembling from a blank sheet. For this reason, there have been drawbacks that extra cost, time and labor are required to increase the cost, and that the user cannot assemble at any time. Furthermore, since the joining portion has a double structure and is bulky, there is a disadvantage that a large space is required for storage, cargo handling, and transportation, and that the shape of the package is unstable. In addition, when used, the bottom surface must be fixed together with the lid surface by tape, etc., which requires extra labor and cost, and the bottom surface tape peels off due to the moisture in the stored items, causing various problems such as the occurrence of bottom loss. Had problems.

[0005] In particular, when forming a long case, two blank sheets have to be separately taken from the original sheet, and it is necessary to fix two splices.

A surface surrounded by a ridge in the length direction and a ridge in the height direction of a rectangular container. The tab surface means a surface surrounded by a ridge in the width direction and a ridge in the height direction of the rectangular container. The bottom surface is three surfaces in a rectangular container, that is, a surface corresponding to the bottom, and the lid surface is one surface in a rectangular container, that is, a surface corresponding to a lid or a ceiling (JIS-Z0201). In the present invention, a side surface continuously provided between the lid surface and the bottom surface is defined as a rear side surface, and a side surface continuously provided only on the bottom surface opposite to the rear side surface is defined as a front side surface. Also,
As for the knob surface, the one connected to the front side is the first knob surface,
What is continuously provided on the rear side surface is a second knob surface, and has a double knob surface structure. Therefore, the case according to the present invention is a case in which the lid surface, the rear side surface, the bottom surface, and the front side surface are successively provided in this order, and the front side surface and the rear side surface are respectively provided with the first and second knob surfaces. is there. In addition, a flap for supporting the lid surface may be continuously provided on the front side surface.

[0008] The "top flap" is one that is provided continuously on the side of the lid surface side of the second tab surface, and is provided with an insertion portion at a part of the base of the continuous portion.

The term "bottom flap" means one connected to the bottom surface side of either the first tab surface or the second tab surface.

The "insertion piece" means a piece provided on the side opposite to the bottom surface of the first tab surface. This insertion piece is provided on a part of the side of the first tab surface, and is inserted into a plug portion provided at a continuous portion between the top flap and the second tab surface to be assembled as a case. That form is maintained. The insertion into the insertion portion may be from either the inside or the outside of the second tab surface. That is, whichever of the first tabular surface provided with the insertion piece and the second tabular surface may be located outside. In order to hold the first tab surface in close contact with the second tab surface during engagement by the insertion tab, it is preferable to provide the insertion tab on the side of the first tab surface on the free end side. The shape of the insertion piece is generally formed in a rectangular shape, but may be formed in a ridge having a thin tip portion in consideration of the operation at the time of insertion, and is not particularly limited. Further, in order to more securely engage the insertion piece with the insertion part, a notch is provided at the base of the insertion piece, and the insertion piece is folded at the notch part, inserted into the insertion part, and then folded.

But,
As described above, it is preferable that the insertion piece is provided on the free end side of the first tab surface, and that the insertion part is formed by notch in consideration of the point that the insertion part is opened when the insertion piece is inserted and the insertion is easy. Is preferred. This means that the position where the insertion portion is provided does not always have to correspond exactly to the insertion piece. Even if the insertion piece is located at the center, the insertion portion is formed by the notch reaching one end of the continuous portion. It may be formed. In short, it is only necessary to provide a notch or hole having a width larger than the width through which the insertion piece can be inserted.

Also, in order to facilitate insertion of the insertion piece,
A cut may be provided in the top flap perpendicular to the end of the insertion portion. This cut is provided at the end of the insertion portion if it is notched, and at least one end if it is a hole. The length of the cut is preferably slightly longer than the height of the insert. Thereby, the insertion portion is opened when the insertion piece is inserted, and the assembling work of the case is simplified. Moreover, when the insertion piece is inserted into the insertion hole from the inside and folded on the upper surface of the top flap, there is an effect of absorbing the swelling due to the thickness of the insertion piece when covered with the lid surface.
