[Blank sheet]
The blank sheet shown in FIG. 8 has a left side surface (end side surface) 1, a front side surface (joint side surface) 2, a right side surface (inner side surface) 3, a rear side surface 4, the back support piece 5 and the joint piece 6 connected in a row. Prepare.
In this example, the rear side surface 4 and the front side surface 2, and the left side surface 1 and the right side surface 3 are square shapes having substantially the same size and shape.

The left side surface 1 and the right side surface 3 of this example are provided with left and right flaps 7, 8, 9, and 10 along the upper and lower end edges, respectively, which are bent toward the opening formed by the four side surfaces and seal the opening. .
The flaps 7, 8, 9, 10 extending from the upper edge or the lower edge of the left side surface 1 and the right side surface 3 are each trapezoidal, and the lengths of the flaps 7, 8, 9, 10 are as follows: Each of the widths of the rear side surface 4 and the front side surface 2 is less than about half.
The left side surface 1 includes a rectangular tag portion T extending from the upper edge of the left side surface 1 to the lower portion of the left side surface 1 at the center thereof, and has a cut S that can be divided around the tag portion T. Prepare.

The cuts S surrounding the tag part T are composed of a double cut formed by alternately arranging two rows of intermittent cuts and a single cut formed by a single row of intermittent cuts.
The above-mentioned double cut has a cut length: intermittent length of 2: 3 to 3: 2 perforation, and the wavelength is 1.5 mm to 3.0 mm by parallel running in two rows with a half-cycle phase shifted. This is formed as a cut S having a square wave shape.
Even though the perforations are thin and short, each perforation can be satisfactorily broken, and there are few irregularities and the touch before breaking is smooth, so even if there is interference with other objects that touch it This is advantageous in that there is little catching.
By setting the distance between the two rows to be substantially equal to the paper thickness of the blank sheet (for example, a width increased or decreased by about 0.5 mm with respect to the paper thickness, etc.), it is difficult for breakage to occur during transportation or stacking. Sometimes it can be easily and visually ruptured.

The incision S in this example runs over the straight single incision (starting incision) s1 along the center of the boundary line between the left side surface 1 and the flap 7 and about 5 mm right below from both ends. Single cuts (conduction cuts) s2, s2 are cut in series, and the straight double cuts (breaking cuts) from the lower end of the left side surface 1 to the upper position of about 20 mm following the guide cuts s2, s2. Cut m and m in parallel.
Further, a series of single cuts (feed cuts) s3 and s3 that run about 10 mm below the break cuts m and m and the straight single cuts (end cuts) s4 connecting the lower ends thereof. By cutting, it becomes the cutting S which continues in a rectangular shape.
Furthermore, when it is desired to divide the tag portion T, a sub-cut s5 that can be divided may be appropriately provided in an intermediate portion in the longitudinal direction.

The front side surface 2 includes an opening break line p that divides the center portion of the upper end portion thereof, and includes the sealing piece 11 that constitutes the bottom portion B along the lower end edge thereof.
The opening break line p is a perforation cut into an inverted trapezoidal shape of a fingertip from the center of the upper edge of the front side surface 2 toward the center of the front side surface 2, and is surrounded by the opening break line p. Form an intrusion in the area.

The rear side surface 4 includes the lid piece 15 constituting the top portion A as an opening portion of the packaging box at an upper end edge thereof and the sealing piece 12 constituting the bottom portion B along a lower end edge thereof. .
The lid piece 15 is cut into a rectangular shape having the same shape as the opening formed on the four side surfaces, and the insertion piece 13 to be inserted along the front side surface 2 of the opening is inserted into the leading edge of the lid piece 15. Prepare along. The insertion piece 13 is preferably formed into a smooth taper toward the tip in order to facilitate insertion into the opening.

The sealing pieces 11 and 12 extend from the lower end edges of the front side surface 2 and the rear side surface 4 as described above.
In this example, the sealing pieces 11 and 12 extending from the front side surface 2 and the rear side surface 4 are both cut into a square shape that is slightly tapered. The length from the lower end edge of the rear side surface 4 to the end edge of the sealing piece 12 is set to a length corresponding to half of the depth (full width) of the left side surface 1 and the right side surface 3, and the front side surface The length from the lower end edge of 2 to the end edge of the sealing piece 11 is sufficiently longer than that and less than the depth (full width) of the left side surface 1 and the right side surface 3.

The back support piece 5 of this example is cut into a rectangular shape having a smaller size than the overlapping left side surface 1. It is desirable that the size difference between the left side surface 1 and the back support piece 5 is as small as possible.
The back support piece 5 extends from the edge of the start end side, and overlaps the back side of the flap 7 extended from the upper edge of the left side surface 1 where the back support piece 5 overlaps, and overlaps the entire width of the tag portion T. A flap 14 is provided.

The joining piece 6 is provided so as to extend in a trapezoidal shape from the side end of the back support piece 5.
The maximum width of the joining piece 6 is made equal to the entire width of the front side surface 2 and the rear side surface 4 in order to improve the shape retaining property, and the upper end portion does not touch the fingertip that enters the penetration portion. A notch is formed such that the position substantially equal to the lower edge of p is the upper edge.
The vicinity of the opening that is not opened may be appropriately cut out while keeping in mind the connection strength of the back support piece 5 (see FIG. 8).

[assembly]
The assembly (three-dimensionalization) of the blank sheet is performed by first connecting the left side surface 1, the front side surface 2, the right side surface 3, the rear side surface 4, the back support piece 5 and the joining piece 6 of the blank sheet. A three-dimensional process is performed in which each of the boundaries is bent at a right angle in the same direction, glue is applied to the joining piece 6, bonded to the front side surface 2, and formed into a cylindrical shape as a whole. The back support piece 5 and the left side surface 1 are not necessarily bonded.

  Next, the flaps 9 and 10 extending from the lower end edges of the left side surface 1 and the right side surface 3 are folded at a substantially right angle toward the lower opening, and the sealing extending from the lower end edge of the rear side surface 4 is performed. The piece 12 is folded on the flaps 9 and 10 at a substantially right angle, and the sealing piece 11 extending from the lower end edge of the front side surface 2 is folded on the flaps 9 and 10 and the tip. A bottom sealing process is performed in which the sheet is folded at a substantially right angle onto the sealing piece 12 and bonded by gluing. The bottom part B is completed by the bottom sealing process.

After filling the contents, finally, the flaps 7 and 8 and the auxiliary flaps 14 extending from the upper end edges of the left side surface 1 and the right side surface 3 are folded substantially at right angles toward the upper opening, and the rear The lid piece 15 extending from the upper end edge of the side surface 4 is folded at a substantially right angle onto the flaps 7 and 8, and the insertion piece 13 extending from the edge of the lid piece 15 is folded to the front side surface. Insert along 2 and glue.
Thus, the packaging box filled with the contents and sealed is completed.
When the flap 7 existing above the tag portion T is bent toward the upper opening, the end portion of the tag portion T facing the start-end notch s <b> 1 is flattened from the flat surface of the flap 7. It protrudes slightly (see FIG. 1B or FIG. 2B).

[Opened]
The packaging box sealed as described above is formed by inserting the penetration portion provided at the upper end portion of the front side surface 2 with a fingertip, and further pulling up the opening break line p provided above the front side surface 2. Is opened and the lid piece 15 is opened in a state of standing rearward (see FIG. 3).

[Separation of tag part]
For example, the packaging box is formed by pressing the front side surface 2 and the rear side surface 4 at the same time to lift the lid piece 15 slightly (see FIG. 1B) and then flattening the flap 7. By hooking a fingertip or the like on the tip portion of the tag portion T slightly protruding from the surface, the vicinity thereof is lifted from the surface of the left side surface 1 (see FIG. 2A), and the raised portion is picked and peeled off. The notch S around the tag portion T is broken, and the tag portion T can be easily separated (see FIG. 2B).

The packaging box has a structure in which the flap 7 supporting the lid piece 15 and the tag portion T are integrated with the left side surface 1 which is the outermost layer, and the packaging box slightly protrudes from the surface of the flat flap 7. The front end portion of the tag portion T is sufficiently covered by the lid piece 15 (see FIG. 1A), and has an effect of preventing unnecessary force from being applied to the front end portion during transportation or packaging (cue protection). function).
In addition, by adopting the double cut as the cut S provided at the place most susceptible to interference from the outside, the surface becomes smooth and necessary while obtaining the effect of preventing unexpected breakage due to the interference. The corresponding breakage is facilitated, and even the cut surface after the breakage has a good appearance (convenient function).

The separated tag portion T becomes a strip-shaped tag that can be viewed at a glance by the display portion D on which the contents information is written (see FIG. 7).
The packaging box according to the present invention lacks the portion where the tag portion T is present and the back support piece 5 is exposed, but the exposure of the contents can be avoided (blind function).
Moreover, if the design etc. which are the same as the part isolate | separated on the surface of the said back support piece 5 are printed, the appearance after isolation | separation will also become favorable.

The present invention is not limited to the above embodiment, and the form of the tag portion T or the configuration of the four side surfaces, the top portion A, or the bottom portion B is not limited to the clue protection function, the convenience function, and the blindfold. As long as the function is not impaired, it can be changed as appropriate.
The material of the packaging box can be selected freely such as paper or plastic. The shape of the fold line and the notch can be changed as appropriate as long as the function is not impaired.
