  In the tamper-proof packaging box of Patent Document 1, a through hole provided in the folded piece and the lock piece inserted into the through hole appear outside. For this reason, there is room for improvement as a packaging box for products such as cosmetics whose appearance is impaired and whose appearance is important.

  In the packaging box of Patent Document 2, since the attachment piece is constituted by a part of the lid, when the attachment piece is bent, a part of the lid is cut out and the part appears outside. Therefore, this box also does not have a good appearance, and cannot satisfy the user's request as a packaging box for products such as cosmetics.

  Therefore, an object of the present invention is to realize and provide a packaging box provided with a function of preventing falsification without impairing the appearance.

In order to solve the above-described problems, in the present invention, the tamper-proof packaging box is configured as follows.
That is, four side walls constituting the rectangular tube, an upper lid for closing the upper opening of the rectangular tube and a bottom lid for closing the lower opening, a pair of opposed inner flaps folded inside the upper lid, and one side of the upper lid It is provided with an insertion piece that continues through a break line, and a backing piece that is connected to the tip of the insertion piece via a crease line,
The inner flaps are connected to the end portions of the two side walls facing each other via a crease line, and the upper lid is connected to the upper end of the side wall adjacent to the side wall where the inner flaps are connected to each other via a crease line. And
The backing piece is folded at the position of the crease line between the insertion piece and superimposed on the back surface of the insertion piece,
The backing piece has a cutout portion and a cutout portion that create a locking groove in each of the width direction center portion and both side portions along the breaking line of the back surface of the insertion piece,
The pair of inner flaps has a protrusion corresponding to each of the locking grooves on an edge placed on the front end side of the upper lid in the assembled state of the box,
The locking produced in the state in which the protrusion is formed on the back side of the insertion piece in a state where the insertion piece is inserted between a side wall at a position opposite to the side wall where the upper lid is connected and a side edge of the inner flap. The box was locked in the groove.

  In addition, the said bottom cover is comprised by adhere | attaching the flap linked with the lower end of each side wall, etc., and it is set as the lid which cannot be opened unless it tears.

  In this tamper-proof packaging box, a mooring piece is continuously connected to the tip of the backing piece via a break line, and the mooring piece is attached to the back surface of the upper lid, and the backing piece is held in place by the mooring piece. A structure is preferable.

  However, the backing piece can be attached to the back surface of the insertion piece and held by the insertion piece. In that case, the mooring piece is not necessarily required.

  The tamper-proof packaging box according to the present invention is configured such that a back cover piece is overlapped on the back side of the insertion piece, and the locking groove is formed on the back side of the insertion piece at a notch provided in the back support piece. Since the protrusion formed on the side edge of the inner flap enters the locking groove and is locked when the piece is inserted between the side wall and the side edge of the flap, The locked state with respect to the locking groove cannot be released from the outside.

  For this reason, in order to open an upper cover, it is necessary to cut | disconnect the said upper cover from a side wall along the said fracture line, and, thereby, opening and tampering by mischief are prevented.

  In the tamper-proof packaging box according to the present invention, since the protrusions are locked to the locking groove on the back side of the upper lid, there is no exposure to the outside of the locking portion that deteriorates the appearance, and the appearance is important. It will be a good-looking box that can be used without any problems in packaging.

It is a perspective view which shows the open state of an upper cover.

  Hereinafter, an embodiment of a tamper-proof packaging box according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the exemplary tamper-proof packaging box 1 includes four side walls 2 to 5 constituting a square tube, an upper lid 6 that closes one end opening of the square tube, and a bottom that closes the other end opening. A lid 7, a pair of opposed inner flaps 8, 8, an insertion piece 10 connected to one side of the upper lid 6 via a breaking line 9, and a mooring indirectly connected to a backing piece 11 directly connected to the insertion piece 10 A piece 12 is provided. Reference numeral 13 denotes an adhesive margin for joining the side walls 3 and 4 together.

  The inner flaps 8, 8 are connected to end portions of the two side walls 4, 5 facing each other via a crease line 14, and the upper lid 6 is an upper end of the side wall 2 located adjacent to the side walls 4, 5. Are connected via a crease line 15.

  The backing piece 11 is connected to the distal end of the insertion piece 10 via a crease line 16, and the anchoring piece 12 is connected to the distal end of the insertion piece 10 via a break line 17. ing.

  The bottom lid 7 of the exemplary tamper-proof packaging box includes large-size flaps 7a and 7a connected to the lower ends of the side walls 2 and 3 via a crease line 18 and a crease line 19 at the lower ends of the side walls 4 and 5, respectively. This is a combination of small size flaps 7b, 7b arranged continuously through the.

  The large-size flaps 7a and 7a are flaps having a well-known shape that are partially engaged with each other in the assembled state of the box, and each has a glue margin 20.

  The glue margin 20 is glued to the back surface of the small-size flap 7b to assemble the bottom lid 7, so that the bottom lid 7 cannot be opened unless it is broken.

  The bottom lid 7 is not limited to the illustrated form as long as it cannot be opened unless it is broken.

  The backing piece 11 has a cutout portion and a cutout portion that respectively form a locking groove 21 at the width direction center portion and both side portions of the insertion piece 10 along the broken line 9 on the back surface.

  Further, the pair of inner flaps 8, 8 has protrusions 22 corresponding to the respective locking grooves 21 on the edge placed on the front end side of the upper lid 6 in the assembled state of the box.

  In this tamper-proof packaging box 1, the backing piece 11 is folded in advance at the position of the crease line 16, overlapped on the back surface of the insertion piece 10, and the mooring piece 12 bent along the breaking line 17 is glued on the back surface of the upper lid. Paste using double-sided tape.
