Each is enclosed.

  Next, an example of an assembly method of the packaging box 10 of this embodiment will be described. 3 is a view of the surface of the box-forming piece 12 of the packaging box 10, and the folding method in which the surface of the box-forming piece 12 is convex and the back surface is convex. Is called reverse folding.

  First, paste 72 is applied along the side edge portion 14a in the vicinity of the side edge portion 14a of the front plate 14 to the back surface of the box forming piece 12, and the paste 74 is applied to the pair of glued portions 44 of the front plate 14 respectively. Then, the glue 76 is applied to each of the pair of glued portions 68 of the glued piece 22. The glues 72, 74, and 76 are, for example, hot melts and seals. Next, the box-forming piece 12 is opened with the back side facing up, and the stored items are placed in a predetermined position. Then, the pair of crease lines 56 and crease lines 60 are normally folded at 90 °, and the side face 54 and the insertion piece 58 are raised in an L shape perpendicular to the back plate 18, and the crease lines 28 and the crease lines 30 are moved to 90 °. The bottom plate 20 and the glued piece 22 are raised in an L shape perpendicular to the back plate 18 by folding the plate 62 at a right angle. Plug in. The back surface of the glued portion 68 of the glued piece 22 is glued to the surface of the insertion piece 58 by glue 76.

  Next, the crease line 26 and the curved fold line 24 are normally folded at 90 °, and the top plate 16 and the front plate 14 are raised in an L shape perpendicular to the back plate 18. At this time, the crease lines 50 and 51 are Then, the folding line 48 is folded by folding the crease line 52 in reverse, and is overlapped on the back surface of the side surface 54. The back surface of the front plate 14 is glued to the surface of the glued piece 22 with glue 72, and the back surface of the glued portion 44 of the front plate 14 is glued to the surface of the glued portion 68 of the glued piece 22 with glue 74, FIG. The packaging is completed as shown in FIG. In the packaging box 10, two curved folding lines 42 are bent at an obtuse angle, and the front plate 14 is bent along the shape of the curved folding lines 24, so that the central portion is deformed in a direction in which the central portion gently bulges outward. Floats from the glued piece 22 to create a gap.

  Moreover, the assembly process of the packaging box 10 may be other than the above. For example, before putting the contents in the box-forming piece 12, the glue 72 and glue 74 are applied, the crease line 30 is first fold-folded, the crease line 26 is then fold-folded, and the back surface of the front plate 14 is glued. It may be in a folded state glued to the attachment piece 22 and shipped in this state. After shipment, the bent fold line 24 and the crease lines 26, 28, and 30 are normally folded at 90 ° at a factory where the contents are put, and the front plate 14, the top plate 16, the back plate 18, and the bottom plate 20 are square. The container may be put in a box, and then the side surface 54 and the insertion piece 58 may be assembled and sealed.

  Next, a method for opening the packaging box 10 will be described. When opening, a finger is put into the opening 36, inserted into the back surface of the knob 38, and pulled up. At this time, since the knob 38 is deformed in the direction in which the front plate 14 bulges outward, a gap is generated by floating from the surface of the glued piece 22 located in the opening 36, so that the finger can be easily Can be plugged into the back. If the pulling is continued, the breaking line 34 is cut, and the lid portion 32 is separated from the front plate 14 and greatly opens upward as shown in FIG. At this time, the folding piece 48 is spread, the upper surface plate 16 is opened continuously to the lid portion 32, and the two directions of the front surface and the upper surface of the packaging box 10 are opened. When the curved folding line 24 is pushed into the inside of the packaging box 10 when inserting a finger into the back surface of the picking portion 38, the deformation of the front plate 14 becomes larger, and it becomes easier to open.

  When the lid 32 is closed again after opening the packaging box 10, the insertion piece 42 formed by the cutting line 40 of the lid 32 is inserted into the slit 66 of the glued piece 22 and resealed. When discarding the used packaging box 10, the glued portion 44 of the front plate 14 is pushed to cut the breaking line 46, and the glued portion 44 is separated from the front plate 14. The gluing is released and the box can be folded, making it easy to discard. When the glued portion 44 is pressed, the glued portion 68 of the glued piece 22 is simultaneously separated from the glued piece 22 and the glued with the insertion piece 58 is released.

  According to the packaging box 10 of this embodiment, the break line 34 can be easily cut with a simple structure, and the lid 32 can be opened and opened. When the cutting of the breaking line 34 is started, the knob 38 is lifted from the glued piece 22 to create a gap, and the user can easily put the finger on the back surface of the knob 38 and pick it. Since the knob 38 is easily picked and opened, it is not necessary to apply a strong force, and damage to the packaging box 10 and the contents can be prevented. Moreover, the deformation | transformation of the front board 14 becomes large by pushing the curved folding line 24, and it can make it easier to pick. The portion surrounded by the two curved folding lines 24 has a convex lens shape, which can enhance the impression of appearance.

  In addition, the packaging box of this invention is not limited to said each embodiment, The magnitude | size and shape of each side surface, the structure of a bottom part, etc. can be changed freely. The assembly process of the packaging box may be other than the above.
