  Next, an example of an assembly method of the packaging box 10 with a buffer function according to this embodiment will be described. Here, FIG. 5 is a view of the surface of the box-forming piece 12 of the packaging box 10 with a buffering function. 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, the crease line 58 is normally folded, the glue 98 is applied to the surface of the partitioning glued piece 54, the crease line 46 is forwardly folded, and the surface of the partitioning glued piece 54 is glued to the back surface of the side face 16. Then, the crease line 66 is reversely folded, and the reinforcing piece 64 is folded and overlapped on the surface of the rising piece 50. Next, the crease lines 38, 74, and 90 are forwardly folded, the crease lines 42 and 78 are reversely folded, and the glue 100 is applied to the back surface of the bottom glued piece 40 and the glue 102 is applied to the back surface of the bottom glued piece 76. . Then, the crease line 26 is forward-folded, the paste 104 is applied to the surface of the glued piece 22, and then the crease line 30 is forward-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 100, and the bottom glued piece 76 is glued to the surface of the second bottom lid piece 88 by glue 102. As a result, the box-forming piece 12 is folded and shipped in this 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 degrees to form a rectangular box. 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 76 of the bottom flap 72 is glued to the second bottom lid piece 88, so that it is folded in two. The ruled lines 38, 46, 74, 90 are automatically raised and open at approximately 90 degrees to form the bottom. At this time, the rising piece 50 of the first bottom cover piece 44 rises from the bottom. Then, the lock piece 92 of the second bottom cover piece 88 is overlapped with the back surface of the end portion 44a of the first bottom cover piece 44, and intersects the upright piece 50 to be erected substantially perpendicularly and is locked to each other. As a result, the bottom portion is prevented from returning to the folded state, and is securely locked and maintains the shape of the bottom portion of the box.

  Further, when the rising piece 50 rises from the bottom, the upper surface piece 52 is caused from the side surface 16, and the rising piece 50 and the upper surface piece 52 are positioned so as to intersect each other in an obtuse L-shape at the crease line 58. And the punching part 62 is opened toward the center of a box, and the packaging box 10 with a buffer function is assembled as shown in FIG.

  In this state, as shown in FIGS. 2 to 4, the accommodation 106 is put in the box. The accommodation 106 is set by being fitted to the punched portions 62 of the rising piece 50 and the upper face piece 52. At this time, the reinforcing piece 64 abuts against a portion of the accommodation 106 on the side surface 20 side, is pushed by the accommodation 106 and slightly bends, and the folding line 67 is bent. As a result, the object 106 is pressed against the punching portion 62 and securely held. In addition, the instruction manual 108 of the storage object 106 is sandwiched and stored between the distal end portion and the side surface 20 rather than the folding line 67 of the reinforcing piece 64.

  Next, the upper flaps 32, 68 are normally folded at the crease lines 34, 70, and then the upper lid piece 80 is normally folded at the crease line 82, and the crease line 86 is further folded forward so that the insertion piece 84 is placed inside the side surface 16. Plug in and close. The portion surrounded by the insertion piece 84 and the break line 43 of the side surface 16 may be glued.

According to the packaging box 10 with a buffer function of this embodiment, a box body can be formed with a simple structure, and the rising piece 50 and the upper face piece 52 can be provided at a predetermined angle. There is an effect. First, since the reinforcing piece 64 is provided, the strength of the rising piece 50 is increased, and the shape of the rising piece 50 and the upper face piece 52 can be maintained even if the container 106 is pushed into the box. The upright piece 50 and the upper surface piece 52 are provided so as to be inclined downward as they approach the center of the box, and therefore when the accommodation object 106 is inserted from above, the accommodation object 106 contacts the upper surface piece 52. It can be easily inserted by being lowered along the inclination while being in contact with the punching portion 62. Even when the container 106 is a glass bottle having a flat bottom as described in the background art, for example, when the container 106 is lowered along the inner side of the side surface 16 away from the reinforcing piece 64, the container 106 comes into contact with the reinforcing piece 64. The upper surface piece 52 can be reached without being lowered, and then it can be lowered along the inclined upper surface piece 52 and easily put into the punched portion 62. Furthermore, the distal end portion of the reinforcing piece 64 is bent along the folding line 67 and becomes substantially parallel to the side surface 16, so that the instruction manual 108 can be easily inserted. Either the instruction manual 108 or the stored item 106 may be inserted first, and the order of insertion is not limited, and work efficiency is good. The bottom lock piece 92 of the second bottom cover piece 88 intersects with the rising piece 50 of the first bottom cover piece 44 at a substantially right angle and is locked to each other so that the assembled box is folded flat. It does not return, and the efficiency of assembly work is improved. It can be assembled stably by either automatic assembly by machine or manual assembly.

  Further, the object 106 is held by being pressed against the peripheral edge of the punched portion 62 by the reinforcing piece 64, and does not rattle during transportation and has a high buffering effect. Further, by storing an instruction manual or the like between the side surface 20 and the reinforcing piece 64, the storage object 106 is held with a more buffering effect, and the safety is also high. The container 106 does not contact the outer surface of the box such as the side surfaces 14, 16, 18, 20 and the like, and even if an impact is applied from the outer surface, the influence is small and damage can be prevented. Further, since the rising piece 50 is provided with the reinforcing piece 64 and the crease line 63, the strength is increased, and even when a force is applied from above when inserting the object 106, the rising piece 50 is not bent and the work efficiency is good. . Even when a downward force is applied to the accommodation 106 during transportation, the rising piece 50 is safe without being bent.

  The packaging box with a buffer function of the present invention is not limited to the above embodiment, and the rising piece and the top piece may be continuously provided on a member other than the first bottom cover piece, The shape and the shape of the punched portion can be changed as appropriate according to the shape and number of items to be stored. 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.
