  Next, an example of an assembly method of the packaging box with a partition 10 according to this embodiment will be described. Here, FIG. 2 is a view of the surface of the box-forming piece 12 of the packaging box 10 with a partition. The folding method in which the surface of the box-forming piece 12 is convex is forwardly folded, and the back surface is convex. This folding method is called reverse folding.

  First, glue 134 is applied to the vicinity of the crease line 58 on the back surface of the first bottom cover piece 52, the crease line 58 is normally folded, and the bottom folded piece 56 is glued to the back surface of the first bottom cover piece 52. At this time, the first partition component 60 is overlaid on the back surface of the side surface 14.

  On the surface of the first partition component 60, glue 135 is applied to the partition support piece 104 at equal intervals along the five end portions 72a, and the crease line 34 is forward-folded to form the middle partition piece 32 as the first partition component. The surface of the part 60 is glued. Adhesives 136 and 138 are respectively applied to the vicinity of the crease line 94 and the inner side of the glued portion 112 on the back surface of the side folded piece 88, and the crease line 90 is forwardly folded to glue the side folded piece 88 to the back surface of the side surface 18. Then, glue 140 is applied to the surface of the folded piece 96 of the second partition component 92 at four locations along the crease line 94, the crease line 94 is reversely folded, and the second partition component 92 is turned to the side folded piece 88. Glue to the surface. The crease lines 54, 82, 118, and 132 are forwardly folded, the crease lines 86 and 126 are reversely folded, and glue 142 and 144 are applied to the back surfaces of the glued pieces 84 and 124, respectively. Glue 146 is applied at two locations in the vicinity of both end portions between the end portion 32 b and the fold line 38 on the surface of the middle partition piece 32, and the crease line 26 is bent. Then, the surface of the middle partition piece 32 is glued to the back surface of the partition support piece 104 of the second partition component 92 with glue 146. Further, the back surface of the glued piece 84 is glued to the surface of the first bottom cover piece 52 with glue 142. A part of the glued piece 22 overlaps the glued piece 124, but the glued piece 124 is pulled out and overlaid on the surface of the glued piece 22. Then, the paste 148 is applied to the surface of the glued piece 22 along the vicinity of the crease line 24, the crease line 30 is normally folded, and the glued piece 22 is glued to the back surface of the side face 20. Further, the back surface of the glued piece 124 is glued to the surface of the bottom flap 130 with glue 144. Thereby, the box-forming piece 12 is in a folded state, and the packaging box 10 with a partition is shipped in this folded state.

  Next, in a factory or the like for storing and packaging the contents, the crease lines 24, 26, 28, and 30 are each normally folded at 90 ° to form a rectangular cylinder. At this time, the crease line 34 on the side of the middle partition piece 32 is normally folded at 90 °, and the middle partition piece 32 is erected between the side surfaces 14 and 18 along the center of the box. The four small partition pieces 66 of the first partition component 60 attached to the back surface of the middle partition piece 32 have the crease line 74 forwardly folded at 90 ° and the crease line 70 reversely folded at 90 °. The two small partition pieces 66 rise at a right angle with respect to the middle partition piece 32 and divide the space between the middle partition piece 32 and the side surface 14 into five equal parts. The four small partition pieces 98 of the second partition component 92 attached to the surface of the middle partition piece 32 have the crease line 106 folded backward at 90 ° and the crease line 102 forward folded at 90 °. The two small partition pieces 98 rise at a right angle with respect to the middle partition piece 32 and divide the space between the middle partition piece 32 and the side surface 18 into five equal parts.

  When the packaging box 10 with an intermediate partition is assembled into a box, the first bottom cover piece 52 slides while pressing the back surface of the intermediate partition piece 32 and becomes perpendicular to the intermediate partition piece 32. At this time, the middle partition piece 32 is easily forward-folded from the folding line 38 and moves smoothly without hindering the movement of the first bottom cover piece 52. The first bottom cover piece 52 and the second bottom cover piece 116 are raised at right angles to the side surfaces 14 and 18, respectively, and the end portion 52 a of the first bottom cover piece 52 is an opening edge of the second bottom cover piece 116.

It is locked to. Thereby, a bottom part is formed. The lower end 32c of the middle partition piece 32 reaches the bottom, and the surface direction of the middle partition piece 32 abuts on the first bottom lid piece 52 and the second bottom lid piece 116 at a right angle. The second bottom cover piece 116 is prevented from returning in the folding direction.

  Then, the stored items are put in the space divided into 10 equal parts by the middle partition piece 32 and the small partition pieces 66 and 98, respectively. The container is a glass vial or the like. The upper flaps 76, 126 are normally folded at 90 ° along the crease lines 78, 128, the crease lines 42, 46 are normally folded at 90 °, and the insertion piece 44 is along the side fold piece 88 on the back surface of the side surface 18. Insert and lock. The glued portion 112 of the side folded piece 88 is glued to the insertion piece 44 and sealed.

  When taking out the contents, the glued portion 108 on the side surface 18 is pushed to cut the breaking line 110 for opening and the breaking line 114 for opening the side folded piece 88, and the glued portions 108 and 112 are glued to the insertion piece 44. In this state, the upper cover piece 40 is opened. The contents are taken out from the opening where the upper lid piece 40 is opened. The side surface 14 is provided with a pair of break lines 50 continuous to both ends of the upper cover piece 40 and a crease line 48 connecting the pair of break lines 50, and the upper cover piece 40 is separated to cut the pair of break lines 50. Then, the side edge of the side surface 14 is opened so that the crease line 48 becomes a hinge, thereby making it easy to take out the contents.

  After discarding the contents, when discarding the packaging box 10 with a partition, put a finger on the inside of the opening recess 122 of the second bottom cover piece 116 from the bottom, and end the first bottom cover piece 52 The vicinity of 52c is pushed inside the box. The first bottom cover piece 52 is folded inside the box and separated from the second bottom cover piece 116 to release the engagement. Since it is in contact with the back surface, the engagement cannot be released. However, when strongly pressed with a certain amount of force, the end portion 52a of the first bottom cover piece 52 pushes the portion on the glued piece 22 side of the end portion 32c of the middle partition piece 32 in the folding direction. Then, the fold line 36 provided on the glued piece 22 side of the inner partition piece 32 is reversely folded and moves to the back side of the first bottom cover piece 52, and the first bottom cover piece 52 is placed inside the box. It can be folded. As a result, the engagement of the first bottom cover piece 52 and the second bottom cover piece 116 is released, the shape retaining property of the box is lost, the crease lines 26 and 30 are folded in two, and the crease lines 24 and 28 are 180 °. Open to a flat folded state. In this state, a plurality of packaging boxes 10 with a partition can be stacked, and a shape suitable for disposal is obtained.

  According to the packaging box 10 with an intermediate partition of this embodiment, the inner side of the box body is partitioned by the inner partition piece 32 and the small partition pieces 66 and 98, and a plurality of products can be accommodated in a buffer manner. Since the middle partition piece 32 reaches the vicinity of the bottom, it faces the side surface of the stored item in a wide area, has a high buffering effect, and can be transported and stored while securely protecting the stored item. Further, since the middle partition piece 32 reaches the vicinity of the bottom portion, the first bottom cover piece 52 and the second bottom cover piece 116 can be prevented from returning in the folding direction, and the shape retaining property is high. Easy to put in and out and good work efficiency. Furthermore, when discarding the packaging box 10 with a partition after use, it can be folded into a flat state by a simple operation, and can be disposed in a flat folded state for compact disposal and resource recovery. In addition, the assembling process and the folding process can be easily performed with one touch.

  In addition, this invention is not limited to the said embodiment, The arrangement | positioning and order of connection of a side surface, a bottom cover piece, and an upper cover piece of a box-forming piece can be changed freely. The number and shape of the small partition pieces can be appropriately changed according to the number and shape of the items to be accommodated. The middle partition piece may be in contact with the bottom, or may be provided slightly spaced from the bottom.
