The disassembling pressing portion 74 is surrounded by a central portion of the crease line 72 and an arc-shaped disassembling breaking line 76 and is separated from the periphery. Furthermore, a pair of breaking break lines 78 are provided outward from the both ends of the breaking break line 76 along the crease line 72.

  Next, an example of a method for assembling the packaging box 10 will be described. Here, the folding method in which the front surface of the box-forming piece 12 shown in FIG. 2 is convex is referred to as normal folding, and the folding method in which the back surface is convex is referred to as reverse folding.

  First, the crease line 30 is folded forward, the glue piece 22 is overlapped on the second side plate 20, and the glue is applied to the surface of the glue piece 22. Then, the crease line 26 is forward-folded so that the side plate 14 and the first side plate 16 are superposed on the side plate 18 and the second side plate 20, and the glue piece 22 is glued to the back surface of the side plate 14. The box forming piece 12 is shipped in a folded state to a factory or the like for packaging the contents.

  Next, the box-forming piece 12 is three-dimensionally assembled at a factory or the like for packaging the contents. First, the crease lines 24, 26, 28, and 30 of the box formation 12 are each normally folded at 90 degrees to form a rectangular cylinder 80. Thereafter, in order to provide a bottom portion 82 for closing one end portion of the cylindrical body 80, the side flaps 36 and 60 are each normally folded at 90 degrees by the crease lines 38 and 62, and the inner bottom piece 70 is formed by the crease line 72 and the breaking line 78 for disassembly. Fold it forward 90 degrees. Thereafter, paste is applied to the center of the back surface of the outer bottom piece 52, the outer bottom piece 52 is normally folded at 90 degrees along the crease line 54, the outer bottom piece 52 is glued to the surface of the inner bottom piece 70, and the outer bottom piece 52 and the inner bottom piece 70 are glued. Are formed as a unitary bottom 82. Thus, one end of the cylindrical body 80 is closed, and an unillustrated container is put into the end from the open end.

  When the container is inserted, the side flaps 32 and 56 are normally folded at 90 degrees by 34 and 58 to close the open end of the cylindrical body 80, and the inner lid piece 64 is folded by the second crease line 66. Fold it forward 90 degrees. Further, paste 84 is applied to the center of the back surface of the glued portion 48 of the outer lid piece 40, the outer lid piece 40 is normally folded at 90 degrees along the crease line 42, and the glued portion 48 is glued to the surface of the inner lid piece 64. The lid portion 86 in which the outer lid piece 40 and the inner lid piece 64 are integrated is formed. Thus, the packaging box 10 is assembled as shown in FIG. As shown in FIG. 1 (b), the lid 86 has a resealing tongue 46 a of the outer lid piece 40 and a resealing notch 68 of the inner lid piece 64, and the central portion of the opening end of the cylindrical body 80. Thus, it faces in the thickness direction.

  When opening the packaging box 10, first, the opening tongue 46 a is picked with a finger, a force is applied in a direction to separate the reseal portion 46 from the glue portion 48, and the opening break line 44 is broken. Since the opening tongue 50 is provided so as to extend inside the opening through-hole 50, it can be easily picked. The reseal portion 46 is narrower at the end portion on the resealing tongue portion 46a side than the end portion on the first side plate 16 side, and the interval between the pair of opening break lines 44 is Since it becomes wider as it gets closer to the first side plate side 16, the breaking line 44 for opening can be easily broken.

  After breaking the opening breaking line 44, as shown in FIG. 3A, the opening 46 is lifted and opened, the inner lid piece 64 integrated with the gluing portion 48 is lifted and opened, and the side flap 32 is opened. , 56 are pulled up and opened, and the contents contained therein are taken out.

  When the lid 86 is resealed, the side flaps 32 and 56 are folded forward at 90 degrees along the crease lines 34 and 58, the inner lid piece 64 is folded forward at 90 degrees along the second crease line 66, The sealing part 46 is normally folded at the first crease line 42. In this state, as shown in FIG. 1 (b), the resealing tongue 46 a overlaps the outside of the inner end portion 64 a of the inner lid piece 64 at the center of the opening end of the cylindrical body 80. become.

  Then, a finger is applied to the resealing tongue 46 a and lightly pushed in the direction of the inner lid piece 64. Then, the first crease line 42 and the second crease line 66 are bent deeper than 90 degrees, and both the reseal portion 46 and the inner lid piece 64 sink, and eventually the end portion of the inner lid piece 64 on the back portion 68a side. And the resealing tongue 46a do not overlap and sink further, and the resealable tongue 46a enters inside the end of the inner lid piece 64 on the back part 68a side. Since the reseal notch 68 is not closed at the entrance of the reseal tongue 46a (is an open entrance 68a), the reseal notch 68 of the inner lid piece 64 is The both side portions sandwiched are spread or twisted and deformed well, and the resealing tongue 47a can smoothly and smoothly enter the inside of the reseal notch 68.

  Thereafter, when the finger is released from the resealing tongue 46a, the sacrificial resealing part 46 and the inner lid piece 64 return to the original state, and the resealing tongue 46a enters deeper into the reseal notch 68. 3 is firmly engaged, and the resealed state shown in FIG.

  When discarding the packaging box 10, first, the disassembling pressing portion 74 of the second side plate 20 is pushed with a finger to break the disassembling breaking line 76, and the disassembling pressing portion 74 and the bottom portion 82 are further connected to the second pressing portion 74. A force is applied in a direction away from the side plate 20 to break the breaking line 78 for decomposition. Thus, the bottom 82 and the side flaps 36 and 60 can be pulled up, and the packaging box 10 can be folded flat and discarded in a compact manner.

  As described above, the packaging box 10 is composed of a single box-forming piece 12 and is easy to assemble with a simple structure. Further, after opening the seal end type lid 86, it can be easily resealed by a simple operation. In particular, in the state where the glued portion 48 of the outer lid piece 50 is glued to the inner lid piece 64, the resealable tongue 46a and the reseal notch 68 are in the thickness direction at the center of the open end of the cylindrical body 80. Therefore, when resealing, it is possible to easily and smoothly reseal by performing an operation of lightly pushing the resealing tongue 46a with a finger as described above. In this regard, the resealing structure of the packaging box of Patent Document 1 makes it difficult to reseal when the outer shape of the box does not satisfy a specific condition, but the structure of the packaging box 10 has various outer packaging shapes. The box can be resealed with a simple operation.

  In addition, the packaging box of this invention is not limited to the said embodiment. For example, the shape of the re-sealing tongue portion of the outer lid piece and the shape of the re-sealing notch of the inner lid piece can be appropriately changed within the range in which the above-described re-sealing operation is favorably performed.

  The packaging box 10 can be opened by breaking the breaking line 44 for opening, and the method for breaking the breaking line 44 for opening is not limited to the method of grasping and pulling up the opening tongue 46a as described above. . For example, if the condition is satisfied, the opening breaking line 44 can be designed to be more easily broken by pushing the opening tongue 46a toward the inner lid piece 64. In this case, since it is not necessary to make it easy to pick the opening tongue 46a with a finger, the opening through-hole 50 can be omitted.

  The quadrangular cylinder may be formed by four or more side plates, and an appropriate side plate may be selected as the first and second side plates. In addition, the configurations of the bottom, side flaps, glued pieces, and the like can be freely changed. For example, the structure of the bottom portion may be the same as that of the lid portion described above.
