  And in this embodiment, while providing the display part 25 which can stand upright on the top wall 12, the latching | locking part 28 for hold | maintaining this display part 25 in the standing-up state is provided in the sticking wall 13. FIG. Further, in the present embodiment, in the unsealed display state in which the display unit 25 is erected, a part of the second side wall 11B and the top wall 12 on the front side is separated to greatly expose the internal product. Breaking portions 30A and 30B are provided.

  As shown in FIG. 6, the display unit 25 has a second fold curve 17 that is a ridge (boundary portion) with the sticking wall 13, and both ends of the second fold curve 17 toward the second side wall 11 </ b> B. By forming a pair of first piece zippers 26, 26 extending and a breaking ruled line 27 extending between the first piece zippers 26, 26, the inside is surrounded by these. The second folding line 17 constitutes a continuous part for the display part, and the first piece zipper 26 and the breaking ruled line 27 constitute breaking means that detours and extends to both ends of the second folding line 17. The first piece zipper 26 includes a first cut portion 26a extending in a perforated manner along the ridges of the top wall 12 and the second outer flaps 22A and 22B, and a second side wall in the first cut portion 26a. And a second cutting portion 26b extending inwardly from the end portion on the 11B side. The breaking ruled line 27 is formed by providing cutting portions 27b with a predetermined interval on a half-cut line 27a provided between the first piece zippers 26 and 26. As shown in FIG. 7D, the half-cut line 27a cuts the back liner 3 by inserting a blade from the back liner 3 side, and the front liner 2 is an uncut portion that is not cut. The intermediate shin 4 is shown in a state where it is cut halfway, but may not be cut due to elastic deformation.

  As shown in FIG. 6, the locking portion 28 has a cut-and-raised structure that can be pushed inward with the display portion 25 side as a locking portion continuous portion. Specifically, the locking portion 28 includes a pair of first cutting portions 28a, 28a extending so as to extend outward from the second folding line 17 constituting the locking portion continuous portion, and these A second cut portion 28b extending in a perforated manner with a predetermined interval is provided between the tips, and the trapezoidal shape is formed inside these. As shown in FIG. 5, a cutout portion 29 capable of locking the locking portion 28 is provided at the end edge of the first side wall 11 </ b> A located inside the locking portion 28 in the sealed state.

  The separation breaking portion 30A is for separating the upper side walls 11A, 11B, the end walls 18A, 18B, and the top wall 12 from the first outer flaps 21A, 21B. The separation breaking portion 30A is made of a cut tape made of a resin (polypropylene) coated with an adhesive on one surface. This cut tape is attached to the back liner 3 between both ends of each pair of inner flaps 19A, 19B, 20A, and 20B so as to be orthogonal to the center shin 4. Note that the cut tape is stuck in a state of a continuous sheet before being punched out as a blank, and in this state, the cut tape is punched out by a paper punching device. A pair of cut lines 31A and 31B are provided at the end edges of the inner flaps 19A, 19B, 20A, and 20B where the ends of the separation breaking portion 30A are located, and a gripping portion is formed between them when breaking. doing.

  The breaking portion 30B for separation is for separating the front side of the top wall 12 and the second outer flaps 22A and 22B, that is, the portion excluding the display portion 25 together with the upper portion of the side wall 11B. The separation breaking portion 30B includes a zipper 32 provided on the second outer flaps 22A and 22B and a second piece zipper 33 provided in parallel with the breaking ruled line 27. The zipper 32 is provided with a pair of one-piece zippers symmetrically so that the second cutting portions extend in a direction approaching each other. One zipper part 32 a is provided so as to extend on an extension line of the breaking ruled line 27. The second piece zipper 33 extends in parallel to the breaking ruled line 27 and extends between the ends of the other piece zipper portion 32 b of the zipper 32. Note that the end of the zipper 32 on the left side (second outer flap 22A side) in FIG. 6, which is the extending direction of the second cutting portion, constitutes a gripping portion.

  The blank configured in this manner is obtained by, for example, bending the side walls 11A and 11B with respect to the bottom wall 10 and bending the top wall 12 with respect to the side wall 11A in a state where a predetermined product is disposed on the bottom wall 10. The sticking wall 13 is bent with respect to the wall 12. And the sticking wall 13 is made to overlap with the upper end outer surface of the side wall 11B, and it sticks with adhesives (hot melt) which consist of hot-melt resin, adhesives, such as a vinyl acetate emulsion type | system | group. In addition, after the inner flaps 19A, 19B, 20A, and 20B are bent with respect to the side walls 11A and 11B, the outer flaps 21A, 21B, 22A, and 22B are bent with respect to the bottom wall 10 and the top wall 12, and these are similarly performed. And stick. Thereby, it can be set as the sealing state shown in FIG.

  The sealed packaging box is provided with a first piece zipper 26 and a breaking ruled line 27 for partitioning the display unit 25 on the top wall 12 and a second piece zipper 33 for breaking. The structure for holding in the standing state is provided on the sticking wall 13. Moreover, the first piece zipper 26 is provided on the ridges of the top wall 12 and the second outer flaps 22A and 22B, and the breaking ruled line 27 is constituted by a substantially half-cut line 27a. It is possible to minimize the decrease in rigidity at the time.

  Moreover, since the sticking wall 13 has a narrow width which is the total height in the sealed state and has a small sticking area, the repulsive force due to the waist of the corrugated paper 1 is strong. However, in this embodiment, since the holding piece 16 is provided by providing the first cutting line 15 along the second folding line 17, the repulsive force can be reduced. In addition, since the cutting edge by the first cutting line 15 is engaged with the lower surface of the holding piece 16, the sticking wall 13 can be reliably held in the bent state with respect to the top wall 12.

  Then, in a store or the like to which goods are delivered using this packaging box, for example, a part of the side wall 11B, a part of the top wall 12 and a part of the second outer flaps 22A and 22B are broken and removed. The display unit 25 is in an opened display state in which the display unit 25 is erected.

  Specifically, first, the end of one separation breaking portion 30A of the second inner flaps 20A and 20B is gripped and pulled outward. As a result, the second inner flaps 20A and 20B and the side wall 11B are torn and torn. Next, the end of the zipper 32 of the second outer flap 22A is gripped and pulled outward. Accordingly, the second outer flap 22A, the top wall 12 and the second outer flap 22B are broken in this order along the separation breaking portion 30B and the breaking ruled line 27. Thereby, as shown in FIG. 4, each part of the side wall 11B, the top wall 12, and the second outer flaps 22A and 22B can be removed.

  Next, the center of the left edge of the top wall 12 is held and pulled upward. Thereby, the top wall 12 is fractured along the first piece zipper 26 that is the ridge portion of the top wall 12 and the second outer flaps 22A and 22B. Thereafter, the display unit 25 composed of the remaining broken top wall 12 is rotated about the second folding line 17 as a fulcrum, and is in a state of extending flush with the sticking wall 13 (vertical direction). Here, since the 2nd folding line 17 which is the continuous part for display parts of the display part 25 is a ridge part (boundary) of the top wall 12 and the sticking wall 13, the display part 25 is made to stand in the perpendicular direction. In addition, the display unit 25 falls down due to folds.

  Therefore, in this embodiment, the locking part 28 provided on the sticking wall 13 is pushed inward and locked to the notch part 29. Thereby, the display part 25 can be pulled to the back side, and as shown in FIG. 1 and FIG. 2, the display part 25 can be set in the unsealed display state in which the display part 25 is erected from the upper end of the back side wall 11A. In addition, in the present embodiment, since the holding piece 16 is provided by providing the first cutting line 15 along the second folding line 17, the holding piece 16 is in the first cutting line 15 in the standing state of the display unit 25. By engaging the inside, it acts to hold the display unit 25 in an auxiliary manner. As a result, the display unit 25 can be prevented from falling and the standing state can be reliably maintained.

  In the packaging box in the opened display state, the back liner 3 positioned on the inner surface side in the sealed state becomes the display surface 25a positioned on the front side in the display unit 25. That is, at the time of transportation, the display surface 25a is located in the packaging box, and dirt is not attached. Further, even when the packaging boxes are stacked, the display surface 25a is not rubbed. Therefore, the sales promotion effect can be surely obtained by performing predetermined printing on the display surface 25a. Moreover, since the upper end fracture edge of the display part 25 comprises the breaking ruled line 27 by the half-cut line 27a and the cutting part 27b, the back liner 3 is entirely cut in this part. That is, since the upper end of the display unit 25 can be a preset beautiful break edge, a sales promotion effect can also be obtained in this respect.

  8 and 9 show a packaging box of the second embodiment. This packaging box is greatly different from the first embodiment in that the shape of the breaking ruled line 27 is changed. Specifically, in the second embodiment, the arcuate portion 27c is provided on the breaking ruled line 27 in order to provide the arcuate protrusion 25b on a part of the upper end edge of the display unit 25 in the unsealed display state. .

  10 and 11 show a packaging box of the third embodiment. This packaging box is greatly different from each embodiment in that the breaking ruled line 27 is configured by a single zipper and is provided so as to be positioned on a ridge line that is a boundary with the side wall 11B. Moreover, in this 3rd Embodiment, it is set as the structure which provided only the one zipper part 32a instead of the zipper 32 provided in 2nd outer flap 22A, 22B as the fracture | rupture part 30B for isolation | separation.

  Specifically, the blank of the packaging box of the third embodiment does not have the first folding line 14 at the boundary between the second side wall 11B and the top wall 12, as shown in FIG. And in 3rd Embodiment, the standing operation part 34 is provided in the center of these boundary parts. The standing operation portion 34 includes a first cutting portion 34a extending along the ridge line, and a second perforated cutting portion extending inwardly from both ends of the first cutting portion 34a toward the bottom wall 10. 34b, 34b, and a continuous portion 34c formed of a fold line extending between these tips. A single zipper is provided as a breaking ruled line 27 on both sides of the standing operation section 34. In addition, the 2nd cutting part of a single zipper is provided in the center side in which the standing operation part 34 was provided.

  The packaging box of the third embodiment can obtain the same operations and effects as the first embodiment. Moreover, the display unit 25 can increase the display area of the display unit 25 as shown in FIG.
