(Display part of packaging box)
In this packaging box 1, the front side outer flap 61 and the front portion 10 are formed with openings 70 in the top surface portion 60 and the front surface portion 10, and a part of the packaging box 1 is raised above the top surface portion 60 to provide article information (product information). Has a display unit forming region 81 that can be used as the display unit 80 for displaying. Further, notches 63a and 64a are formed in the portions of the first side surface side inner flap 63 and the second side surface side inner flap 64 that overlap with the display portion forming region 81 of the front side outer flap 61.
Although the article information (product information) is not specifically illustrated, it is, for example, a display for appealing the product to consumers, and includes a product name, a mark related to the product, an explanation about the product, and the like.

The display portion forming region 81 is roughly formed in a rectangular shape by the first bending ruled line 82 and the breaking cut line 83 in the front side outer flap 61 and the front portion 10.
The first bending ruled line 82 extends in a straight line along the width direction (and therefore parallel to the folding line 13r) at each intermediate portion in the width direction and the depth direction of the front side outer flap 61. .. In the present embodiment, a linear cut line 82a is intermittently formed along the first bending ruled line 82 (overlapping the first bending ruled line 82).

The breaking cut line 83 includes a pair of left and right first cut lines 84L and 84R extending linearly in the depth direction and the height direction from both ends of the first bending ruled line 82 to the inside of the front portion 10. It is composed of a second cut line 85 extending along the width direction so as to connect the tips of the first cut lines 84L and 84R of the above.

Further, a hole-drilling cut line 86 for guiding the drilling of the finger insertion hole 87 is formed in the intermediate portion (here, the central portion) in the extending direction of the second cut line 85.
The second cut line 85 is formed so as to be inclined upward in the height direction by a small angle from the central portion where the cut line 86 for drilling is formed to the left and right, and the tips of the first cut lines 84L and 84R. The upward tilt angle is large in the region close to.

The second cut line 85 and the cut line 86 for drilling are formed by intermittently forming a plurality of linear cuts. On the other hand, the first cut lines 84L and 84R are a linear inclined notch extending outward in the width direction and upward in the height direction, and a linear notch connected to the tip of the inclined notch and extending in the height direction and the depth direction. A key-shaped notch consisting of is composed of zipper cut lines formed intermittently.

The display portion forming region 81 can be divided into a top surface region 81T in the front side outer flap 61 and a front surface region 81F in the front portion 10 with the polygonal line 13r as a boundary.
A second bending ruled line 88 is formed along the width direction (parallel to the folding line 13r) at a position symmetrical to the first bending ruled line with respect to the folding line 13r in the middle portion in the height direction of the front region 81F. Has been done. As a result, the front region 81F can be divided into a base region 81Fb between the polygonal line 13r and the second folding ruled line 88 and a tip region 81Ft on the tip side of the second folding ruled line 88. .. In the present embodiment, a straight cut line 89 that facilitates bending is intermittently formed along the polygonal line 13r, that is, on the ruled line 13.

When a finger is inserted into the region 87a forming the finger insertion hole 87 in the central portion of the second cut line 85 that partitions the lower edge of the front region 81F, the finger insertion hole 87 is relatively easily drilled by the hole opening cut line 86. If you pinch the lower edge of the front area 81F with your finger inserted into the finger insertion hole 87 and pull it outward and upward of the packaging box 1, the front part will be along the second cut line 85. When 10 is broken and the lower edge of the front region 81F is further pulled up, as shown in FIG. 3A, the front portion 10 is further broken along the first cut lines 84L and 84R, and then further breakage occurs. As it proceeds, it breaks until it reaches the first bending rule line 82.

As a result, the display portion forming region 81 can be bent at each of the first folding ruled line 82, the folding line 13r, and the second folding ruled line 88. When the display portion forming region 81 is folded about 180 degrees along the polygonal line 13r and about 90 degrees valley folds along the first folding ruled line 82, as shown in FIG. 3B, the base region 81Fb of the front region 81F and the sky are folded. The surface region 81T is overlapped back to back, and these are raised above the top surface portion 60. As a result, one surface of the base region 81Fb can be directed to the front side.

Further, when the display portion forming region 81 is folded about 90 degrees along the second bending ruled line 88, as shown in FIG. 3C, the front end region 81Ft of the front region 81F is combined with the back side outer flap 62. It can be inserted between the side inner flaps 63 and 64 that overlap with the rear side inner flaps 63 and 64, whereby the tip region 81Ft can be locked between the back side outer flap 62 and the side surface inner flaps 63 and 64. can.

(Action and effect)
Since the packaging box 1 according to the present embodiment is configured as described above, a plurality of articles (commodities) of the packaging box 1 are accommodated and transferred in a state of being packed with adhesive tape, and after the transfer, the packaging box 1 is transferred. The display portion forming region 81 of the above can be partially broken and opened so that the article inside can be taken out, and the article (commodity) can be displayed and used while being housed in the packaging box 1. ..

Specifically, as shown in FIG. 3A, a finger insertion hole 87 is formed and a finger is inserted to break the second cut line 85 and the first cut lines 84L and 84R of the display portion forming region 81. An opening 70 is formed in the display portion forming region 81 of the top surface portion 60 and the front surface portion 10. The display portion forming region 81 can be easily broken from the front portion 10 and the front side outer flap 61 by the second cut line 85 and the first cut lines 84L and 84R. When forming the finger insertion hole 87, the hole-drilling cut line 86 facilitates the formation.

In a general A-type box, the portion corresponding to the display portion forming region 81 of the top surface portion 60 is a top surface provided on the front side outer flap because the front side outer flap and the side surface side inner flap are overlapped. If only the area is opened, a part of the inner flap on the side surface side interferes with the opening 70. However, in the present packaging box 1, notches 63a and 64a are formed in the portion overlapping the display portion forming region 81 (top surface region 81T) of the side inner flaps 63 and 64 and the front side outer flap 61. Therefore, the side inner flaps 63 and 64 do not interfere with the opening 70, and the opening 70 can be reliably formed.

Then, as shown in FIG. 3B, the display portion forming region 81 is mountain-folded by 180 degrees along the polygonal line 13r and valley-folded by 90 degrees along the first folding ruled line 82 to form the base region of the front region 81F. The 81Fb and the top surface region 81T are overlapped back to back, and these are raised above the top surface 60 so that one surface of the base region 81Fb faces the front side. One surface of the base region 81Fb facing the front side can be used as a display unit 80 for displaying article information (product information). For example, the product can be appealed to the consumer by the product information (product information) displayed on the display unit 80.

Further, as shown in FIG. 3C, the display portion forming region 81 is folded by 90 degrees along the second bending ruled line 88, and the front end region 81Ft of the front region 81F is combined with the rear outer flap 62. It is inserted between the side inner flaps 63 and 64 that overlap with. As a result, as shown in FIG. 4, the tip region 81Ft is sandwiched between the back side outer flap 62 and the side surface side inner flaps 63 and 64, and is engaged with the back side outer flap 62 and the side surface side inner flaps 63 and 64. It can be stopped.

Further, as shown in FIG. 5A, the display portion forming region 81 is separated from the front side outer flap 61 and removed by using the cut line 82a intermittently formed along the first bending ruled line 82. Alternatively, as shown in FIG. 5B, the base region 81Fb and the top region 81T of the front region 81F polymerized back to back are laid down along the top 60 without rising from the top 60. Therefore, the top surface portion 60 can be flattened. In this case, the tip region 81Ft is sandwiched between the back side outer flap 62 and the side side inner flaps 63 and 64.

By preventing the top surface portion 60 from protruding upward in this way, as shown in FIG. 6, another packaging box 1 can be stacked and displayed above the packaging box 1 in which the opening 70 is formed. .. Articles can be taken out not only from the uppermost packaging box 1 but also from the lower packaging box 1.
Further, when the base region 81Fb and the top surface region 81T of the front region 81F polymerized back to back as shown in FIG. 5B are laid down along the top surface portion 60, the upper packaging box 1 is subsequently eliminated. If this is the case, the display unit 80 can be used by raising these overlapping portions from the top surface portion 60. In this case, since the display portion forming region 81 is not separated, there is no problem even if the cut line 82a is omitted.

[Second Embodiment]
The second embodiment will be described with reference to FIGS. 7 and 8. In addition, in FIGS. 7 and 8, the same reference numerals as those in FIGS. 1 to 6 indicate the same ones.
As shown in FIG. 8, the present packaging box 1 stands above the top surface portion 60 in the base region 81Fb and the top surface region 81T of the front region 81F of the display portion forming region 81 in the first embodiment. A locking structure 90 is additionally formed for holding the state of being raised and superposed on each other. Therefore, only the locking structure 90 will be described.

As shown in FIG. 7, the directions (here, right angles) intersecting the first cut lines 84L and 84R at positions where the left and right edges of the base region 81Fb and the top surface region 81T are substantially the same when they are overlapped with each other. ), The locking pieces 91 and 92 formed by processing a pair of notches are formed. Here, the pair of notches are formed in a straight line parallel to each other.

When the display portion forming region 81 is broken along the first cut lines 84L and 84R, the locking pieces 91 and 92 can be bent in a direction deviating from each surface of the base region 81Fb and the top surface region 81T. As shown, one of the locking pieces 91 and 92 is locked by bending the locking pieces 91 and 92 together in one deviation direction in a state where the base region 81Fb and the top surface region 81T are overlapped with each other. A locking structure in which the cut cross section or cross section edge portion 91a of the above is locked to the cut cross section or cross section edge portion 92a exposed on the main body side of the base region 81Fb or the top surface region 81T by bending the other locking piece. 90 is formed.

Since the locking structure 90 is additionally formed, the effect of maintaining the shape of the display unit 80 in the raised state can be obtained, the rigidity of the display unit 80 is increased, and the display unit 80 is less likely to fall down. In particular, when the sheet material 2 of the packaging box 1 is a corrugated cardboard sheet, the locking pieces 91 and 92 are locked with sufficient frictional force because they are thick and the cut section has a certain roughness.
