Description

  The present invention relates to a packaging box that accommodates commodities such as drugs and foods and has a tamper-proof function and a folding function.

  Conventionally, packaging boxes that wrap products such as powerful drugs or drugs containing narcotic ingredients that require management during storage have a tamper-proof function on the top lid and side to prevent tampering. It is sealed with tape. When such a tape is opened, a part of the printing of the tape is transferred to the packaging box, and can be distinguished from the unopened state. However, when opening from the bottom cover piece to which the tape is not stretched, it is not known that the tape has been opened. Moreover, if a tamper-proof tape is attached to the bottom lid piece in order to prevent tampering from the bottom lid piece, there is a problem that costs increase and man-hours increase.

  In order to prevent tampering, there is a method of gluing the insertion part of the upper lid piece of the packaging box and the side of the box. This method can easily distinguish the uncovered state from an unopened state in which a mark remains on the insertion portion and the side surface of the upper lid piece when the package is opened. However, there is a disadvantage that if the glue is cleanly opened after the opening, there is no trace of opening and it is difficult to judge whether or not it has been tampered with.

Therefore, there has been a packaging box disclosed in Patent Document 1 as a packaging box that reliably prevents tampering from the bottom with a simple structure. This is composed of a box-forming piece integrally punched from one blank sheet, and the box-forming piece has a pair of lids for closing the open ends of the box formed by side surfaces connected to each other. A piece is provided. An inner box piece is provided continuously from one side surface to the side surface facing the side surface and the pair of lid pieces, without any seam along the inner wall portion.

  Next, an assembling method of the packaging box 10 of this embodiment will be described. Here, FIG. 1 is a view of the front side of the box-forming piece 12 of the packaging box 10, and in FIG. 2, the folding method in which the front side is convex and the folding side in which the front side is concave are shown. Is called reverse folding.

  First, paste 94 is applied to the back surface of the folded piece 66. Next, the crease line 68 is forwardly folded and the folded piece 66 is glued to the back surface of the side surface 18. Next, glues 96 and 98 are respectively applied to the back surfaces of the glued portion 64 of the glued piece 58 and the glued part 92 of the glued piece 86, and the lower flaps 54 and 82 are normally folded at the crease lines 56 and 84. Then, the glued pieces 58 and 86 are folded back along the crease lines 60 and 88. The inner bottom piece 40 is normally folded at the crease line 42, and the bottom lid piece 70 is normally folded at the crease line 72. Next, glue 100 is applied to the surface of the glued piece 22 and the crease lines 26 and 30 are forward-folded. At this time, the glued piece 22 is set so as to enter between the folded side surface 20 and the lower flap 82, and the surface of the glued piece 22 is glued to the back surface of the side surface 20. At the same time, the back surface of the glued portion 64 of the glued piece 58 is glued to the surface of the inner bottom piece 40, and the back surface of the glued portion 92 of the glued piece 86 is glued to the surface of the bottom lid piece 70.

  Then, each of the crease lines 24, 26, 28, 30 is forwardly folded at 90 ° to form a rectangular box. At this time, the folded crease lines 42, 56, 72, 84 are opened at 90 °, and the inner bottom piece 40 moves smoothly without coming into contact with the side surface 16 because the side surface 16 side is cut away. At this time, the bottom cover piece 70 and the inner bottom piece 40 are pressed by the pair of lower flaps 54 and 82 from the outside of the box to form a bottom portion. Further, the locking piece 44 of the inner bottom piece 40 is normally folded at 90 ° along the crease line 46, and the inner bottom piece 40 is overlaid on the back surface of the bottom lid piece 70, and the locking piece 44 is superimposed on the back surface of the side surface 18. The bottom part is completed. The end portion of the lock piece 44 is locked to the end edge portion of the folded piece 66 glued to the back surface of the side surface 18, and does not inadvertently return upward, so that the shape of the bottom portion is reliably maintained.

  In this state, the product is put in, the upper flaps 50 and 78 are normally folded at the crease lines 52 and 80, the upper cover piece 32 is then folded at the crease line 34, and the crease line 36 is then folded and inserted. The piece 35 is inserted inside the side surface 18. A protrusion is formed on the upper cover piece 32 by a cut line 38 on the crease line 36, and when the upper cover piece 32 is closed, this protrusion abuts against an edge formed by the crease line 68 on the side face 18. The piece 32 is positioned. The upper lid piece 32 and the side surface 18 are stopped with, for example, a tamper-proof tape to prevent tampering.

  When a force is applied to open the bottom lid piece 70 to open the packaging box 10 containing the product from the bottom portion, as shown in FIG. The connecting portion that is intermittently applied by the force is broken, leaving a trace of opening. Three tamper-proof cutting blades 76 are provided, and any one of them is broken and a trace remains reliably. Further, since the inner bottom piece 40 that covers almost the entire bottom portion is provided inside the bottom lid piece 70 while being locked to the folded piece 66, the product cannot be taken out from the bottom portion. Further, when a force is applied so as to peel off the glued portion 64 from the inner bottom piece 40, the connecting portion of the cut line 62 around the glued portion 64 is broken, and an unsealed trace remains. Similarly, when a force is applied so as to peel off the glued portion 92 from the bottom cover piece 70, the connecting portion of the cut lines 90 around the glued portion 92 is broken, and an unsealed trace remains. This also has the effect of preventing tampering.

  When the packaging box 10 is folded to be discarded after the use of the product, the inner bottom piece 40 is pushed from the inside of the punching portion 74 of the bottom cover piece 70 toward the inside of the box as shown in FIG. Then, the abutting piece 44 of the inner bottom piece 40 gets over the folded piece 66 glued to the side face 18 and is unlocked, the bottom part is removed, and it is folded by the crease lines 26 and 30 to become flat and easy to discard. It becomes.

  According to the packaging box 10 of this embodiment, the tampering of the contents can be reliably prevented with a simple structure. That is, when tampering is attempted from the bottom portion, the connecting portion between the tamper-preventing cutting blade portion 76 and the tamper-preventing cutting lines 62 and 90 can be broken to leave a tampering trace. Further, since the inner bottom piece 40 that covers almost the entire bottom portion is provided on the inner side of the bottom cover piece 70 while being locked to the folded piece 66, the product cannot be easily taken out from the bottom portion. Since the anti-tampering cutting blade 76 is provided on the surface of the packaging box 10, it also has a deterrent effect of suppressing tampering such as tampering and extraction.

  In the packaging box of the present invention, the number of tamper-proof cutting blade portions and the interval between the tamper-proof cutting line and the connecting portion can be set according to the strength of the blank sheet and the like. The size of each side surface, upper lid piece, and the like can be changed as appropriate according to the product to be put therein. The positions of the bottom cover piece and the falsification preventing cutting blade may be reversed, and the structure of the bottom portion of the box forming piece of the present invention may be provided at other positions such as the top cover portion.
