  In addition, in order to make it easy to bend each above-mentioned crease line, a break line may be provided.

  Next, an example of an assembly method of the packaging box 10 of this embodiment will be described. Here, FIG. 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. This is called reverse folding.

  First, the paste 108 is applied to the back surfaces of the folded piece 52 and the folded piece paste piece 74. The paste 108 is applied in a straight line shape along the longitudinal direction of the folded piece paste piece 74 from the vicinity of the crease line 72 to the vicinity of the crease line 64.

  Next, the crease line 64 is folded forward and the back surfaces of the folded piece 52 and the folded piece paste piece 74 are glued to the back surface of the rising piece 50. Then, the glue 110 is applied to the surface of the partitioning paste 56. The glue 110 is applied at two locations on both sides of the partition glue piece 56 other than the holding piece 76. Next, the crease line 46 is forward-folded, and the surface of the partition glue piece 56 is glued to the back surface of the side surface 16. Further, paste 112, 114 is applied to the back surfaces of the bottom glued pieces 40, 88, the crease lines 42, 90 are reversely folded, and the crease lines 38, 86 are forwardly folded. Further, the second bottom lid piece 102 is folded forward along the crease line 104.

  Next, glue 116 is applied to the surface of the glued piece 22, the crease line 26 is normally folded, and then the crease line 30 is normally folded, and the back surface of the side surface 20 is glued to the surface of the glued piece 22. At this time, the bottom glued piece 40 is glued to the surface of the first bottom lid piece 44 by glue 112, and the bottom glued piece 88 is glued to the surface of the second bottom lid piece 102 by glue 114. As a result, the box-forming piece 12 is in a folded state, and is shipped in the folded state.

  Next, the crease lines 24, 26, 28, and 30 are each normally folded at 90 degrees to form a rectangular box, for example, in a factory for storing and packaging the items 118. At this time, the bottom glued piece 40 of the bottom flap 36 is glued to the first bottom lid piece 44, and the bottom glued piece 88 of the bottom flap 84 is glued to the second bottom lid piece 102. The ruled lines 38, 46, 86, 104 are automatically caused to open at approximately 90 ° and the bottom 117 is formed. The lock piece 106 of the second bottom cover piece 102 is overlaid on the back surface of the end portion 44d of the first bottom cover piece 44, and the side edge portion 44c abuts in the returning direction. Thereby, the bottom part 117 is prevented from returning to the folded state, and is securely locked and the shape of the bottom part 117 of the box body is maintained.

  Further, when the first bottom cover piece 44 is raised from the side surface 16 and opened at 90 °, the rising piece 50 is bent from the first bottom cover piece 44 to 90 ° along the crease line 58 and rises. The crease line 58 is easily bent at a portion other than the portion where the protrusion 62 is provided, and the protrusion 62 is overlapped on the back surface of the second bottom lid piece 102.

  By assembling the rising piece 50 so as to rise from the bottom portion 117, the folded piece 52 and the folded piece paste piece 74 glued to the rising piece 50 are separated from the side surface 16, and the upper surface piece 54 is reversed at the crease line 66. The sheet is folded and further folded at the crease line 68 so as to be substantially parallel to the bottom 117. Then, the folding piece glue piece 74 and the holding piece 76 are opened away from the central portion of the upper surface piece 54, the holding piece 76 is reversely folded at the crease line 72, and further forwardly folded at the crease line 71, and the bottom portion 117 and the upper surface It is substantially parallel to the piece 54 and is located below the top piece 54. At the center portion of the upper surface piece 54, the folding piece glue piece 74 and the holding piece 76 are opened apart from each other, and communicated with the pair of through holes 79 to form a large substantially circular opening 81. Thus, the partition piece 48 is assembled three-dimensionally, and the packaging box 10 is assembled as shown in FIGS.

  In this state, the contents 118 are put into the box. The contents 118 are set in contact with the insertion holding piece 76 from the bottom in the opening 81 opened in the upper surface piece 54. In addition, the opening part 81 is a magnitude | size which fits the side surface of the accommodation 118 with a slight clearance gap. A space 119 is formed between the rising piece 50 and the side surface 20 to store the instruction manual 120 of the storage item 118 and the like.

  Next, the flaps 32, 80 are normally folded at the crease lines 34, 82, the upper lid piece 92 is then folded at the crease line 94, and the crease line 98 is further folded forward so that the insertion piece 96 is placed inside the side surface 16. Plug in and close. You may glue the part inside the breaking line 43 of the side surface 16, and the insertion piece 96. FIG.

  According to the packaging box 10 of this embodiment, the partition piece 48 can be automatically assembled at a predetermined angle at the same time as the box body and the bottom part 117 are formed with a simple structure with a single touch. The lock piece 106 of the second bottom cover piece 102 is brought into contact with and locked to the side edge 44c of the first bottom cover piece 44, so that the assembled packaging box 10 does not return to the flat folded state and is assembled. Work efficiency is improved.

  Further, the accommodation 118 is fitted to the peripheral portion of the opening 81, and does not rattle even if an impact is applied in the horizontal direction during transportation, and has a high buffering effect. Since the holding piece 76 supports the bottom of the stored item 118 with the surface, it can be reliably held even when an impact is applied in the vertical direction. The holding piece 76 has a cushioning property because it bends slightly when an impact is applied in the vertical direction, and is highly safe. The holding piece 76 is provided with a crease line 78 in the longitudinal direction, and is formed so as to be able to support the contents 118 by increasing rigidity against bending. Furthermore, the contents 118 do not come into contact with the outer surface of the box, such as the side surfaces 14, 16, 18, 20, etc., and even if an impact is applied from the outer surface, the influence is small and damage can be prevented.

  In the packaging box 10, the lock piece 106 is locked to the end portion 44 d of the first bottom cover piece 44, and the end portion 44 b of the first bottom cover piece 44 exceeds the end portion 102 a of the second bottom cover piece 102. Since it has reached the vicinity of the crease line 104, the engagement of the first bottom cover piece 44 and the second bottom cover piece 102 cannot be removed from the outside, and has a high tampering prevention effect. When the first bottom cover piece 44 and the second bottom cover piece 102 are pushed upward to open, the partition piece 48 is also raised, so that tampering can be prevented from this point.

  The packaging box 10 can be stably assembled by either automatic assembly by a machine or manual assembly. When the packaging box 10 is assembled into a three-dimensional shape, an opening 81 for storing the contents 118 and a space 119 for storing the instruction manual 120 are opened separately, which may be inserted first, and the insertion order is limited. Work efficiency is good without. Since the crease line 58 is provided with the protrusion 62, the crease line 58 can be easily folded forward, and the protrusion 62 is superimposed on the second bottom cover piece 102 to increase the strength and the rising piece 50 is stable. Then stand up.

  In addition, the packaging box of this invention is not limited to the said embodiment, A partition piece may be continuously provided in members other than a 1st bottom cover piece, and the shape of each member is a thing to contain It can be suitably changed according to the shape and number of the. The material of the box-forming piece can also be changed as appropriate, such as paper or synthetic resin. The shape of the lock piece is also free, and any shape can be used as long as it can be reliably locked to another member.
