Description

  The present invention relates to a packaging box that is suitably used for packaging an article such as cosmetics, and more particularly to a structure for preventing its unauthorized opening.

  In the case of the above-mentioned cosmetic packaging box, etc., in order to protect expensive items from damage such as shoplifting, there is a conventional measure to prevent unauthorized opening such that once opened, re-sealing cannot be performed or an opened mark remains. It has been subjected. FIG. 6 is a development view showing the structure of the packaging box 5 of Patent Document 1. As shown in FIG. The packaging box 5 is a so-called sack box, which is a rectangular parallelepiped box that is generally formed by closing both open ends 57 of the rectangular tubular body 50 with a lid 56. Since the configurations related to the lids 56 on the two opening ends 57 side are almost common, the corresponding portions will be described with the same reference numerals.

  The body portion 50 includes four wall surfaces 51 to 54 that are connected to each other to form the square cylinder, and a gluing surface 55 that is formed to extend from the side of the wall surface 54 at one end. Is glued to the back surface of the wall surface 51 at the other end. An opening perforation 501 is formed on the body 50 across the three wall surfaces 52 to 54.

  What should be noted in the packaging box 5 is a structure for preventing the lid 56 from being opened. An insertion flap 58 is formed extending from the tip of the lid 56. The insertion flap 58 includes a first flap 581 that is continuous with the lid 56, and a second flap 582 that extends to the tip of the first flap 581, and is folded and folded. A slit 5821 extending in the width direction of the second flap 582 is formed on the distal end side of the second flap 582.

  Correspondingly, in the pair of side flaps 59 provided at each opening end 57, the side 590 facing the insertion flap 58 in the assembled state corresponds to the thickness of the insertion flap 58 folded on the proximal end side. The width D1 is cut out, and the free end side is not cut out, and is a locking piece 591 that fits into the slit 5821.

  Accordingly, the body 50 is assembled, the side flaps 59 are sequentially folded, the insertion flap 58 is folded in a mountain, the lid 56 is bent, and the insertion flap 58 is inserted into the opening end 57, as shown in the cross section of FIG. Further, the locking piece 591 is fitted into the slit 5821, and the lid 56 is prevented from being removed.

JP 2014-198590 A

  The above-described prior art is an excellent packaging box that can prevent unauthorized opening with only the structure on the packaging box side, regardless of the size and shape of the container, that is, without holding the insertion flap or the like with the container. It is. However, the structure for preventing unauthorized opening is realized by the fact that the two locking pieces 591 are fitted into the slits 5821 and do not bend in the thickness direction, and if the lid 56 is pulled with a slightly large force, The locking piece 591 may be bent to escape from the slit 5821 and be opened.

  An object of the present invention is to provide a packaging box that can prevent unauthorized opening more reliably.

  The packaging box of the present invention is a packaging box configured to include a rectangular tube-shaped body portion and a lid that extends from one surface of the rectangular tube at both opening ends of the body portion and closes the opening end. An insertion flap extending from a tip of the lid; and a first tongue piece extending from an opening end of a surface of the body portion opposite to a surface on which the lid is extended and folded inward. The flap is characterized by having a second tongue piece that extends from the distal end side toward the proximal end side and protrudes toward the opposing surface side with the lid closed by cutting and raising.

  According to said structure, it is comprised including a rectangular tube-shaped trunk | drum, and the lid | cover extended from one surface of the said square cylinder in both the opening ends of the trunk | drum, and obstruct | occluding this opening end, for example, a rectangular parallelepiped In the packaging box, the engagement structure is provided between the facing surface, which is formed to extend from the front end of the lid and is inserted into the opening end side of the facing surface in the body portion. Specifically, a first tongue piece that is folded inward from the open end is formed, and the insertion flap is cut and raised to extend from the distal end side toward the proximal end side, and the lid is closed. Then, the 2nd tongue piece which protrudes in the said opposing surface side is formed.

  Accordingly, when the insertion flap is inserted from the opening end, the second tongue piece gets over the first tongue piece, and when the insertion flap is subsequently withdrawn from the opening end, the second tongue piece becomes the first tongue. Engage with the piece. Thus, once the lid is closed, it is possible to prevent unauthorized opening, and to prevent the opening, the second tongue piece is inserted between the first tongue piece and the opposite surface. Thus, in the first and second tongue pieces, a firm engagement structure is realized by the mutually overlapping widths, so that unauthorized opening can be prevented more reliably.

  Moreover, in the packaging box of this invention, it has a folding piece which is folded up from the front-end | tip of the said insertion flap, and is located inside this insertion flap at the time of an assembly, The said 2nd tongue piece is the said folding piece It is characterized by being cut and raised from the vicinity of the base end.

  According to the above configuration, in assembling the packaging box, the second tongue piece does not bother to be raised (without brazing), but the folded piece is inserted and folded in a mountain from the flap. The second tongue piece formed by die cutting or the like from the vicinity of the proximal end naturally comes up.

  Therefore, the assembling work can be easily performed.

  Preferably, the folded piece is formed to have a narrower width than the second tongue piece, so that when the folded piece is folded in a mountain, the twist is easily transmitted to the second tongue piece. Can be erected more easily.

  Furthermore, the packaging box of the present invention is characterized in that the body portion has an even-numbered rectangular tube shape.

  According to said structure, the surface where a lid is extended, such as a square cylinder and a hexagon cylinder, and the surface which opposes can be made mutually parallel, and the assembly operation | work which inserts an insertion flap can be performed easily. it can.

  In the packaging box of the present invention, a side flap is extended from at least one open end of two surfaces adjacent to the opposed surfaces.

  According to said structure, a lid | cover can be received from a back (inner) surface side with a side flap, and it can suppress that a lid | cover fits inward even if the things are shorter than the length of a trunk | drum. .

  Furthermore, in the packaging box of the present invention, the side flap includes a pressing piece that is bent by 90 ° and extends in parallel with the facing surface from the side on the facing surface side.

  According to said structure, since a pressing piece pushes back the said insertion flap and the folded-back folding piece to the said opposing surface side, an insertion flap closely_contact | adheres to the opposing surface, and a folding | turning piece does not open but sticks to an insertion flap I can leave it to you.

  Thereby, even when the stored item is close to the inner diameter of the barrel part, when the stored item is stored in the barrel unit, it is possible to suppress the insertion flap and the folded piece from being caught as a step, It can be stored smoothly.

  Further, in the packaging box of the present invention, a cut is formed from at least one side of the insertion flap at a connection portion with the lid of the insertion flap, and the cut is in the assembled state in the side surface facing the side flap. It is characterized by engaging with the sides.

  According to said structure, it becomes difficult to lift a lid | cover by engagement with a notch and a side flap, and unauthorized opening can be prevented more reliably. The engaging portion between the cut and the side flap may be provided only on one side of the insertion flap, but is preferably provided on both sides.

  Furthermore, the packaging box of the present invention is characterized in that a perforation for opening is formed on one of the lids or the body.

  According to the above configuration, regular opening can be easily performed while preventing unauthorized opening.

  In the packaging box of the present invention, the perforation is formed on the lid.

  According to the above configuration, when the contents are close to the inner diameter of the body part, it is difficult to open if the body part has a perforation, whereas a perforation is formed on the lid. This makes it easy to open.

  Furthermore, in the packaging box of the present invention, the perforation is inserted in a pair at a position shifted outward from the center in the width direction of the lid by a predetermined distance from the connecting portion of the lid and the trunk portion. The connection portion between the lid and the body portion is formed over the connection portion with the flap, and a cut is formed between the pair of perforations.

  According to said structure, the center part of this cover peels along the perforation of both sides by lifting this cover from the notch in the connection part of a cover and a trunk | drum. By the way, when trying to check the contents, the top end of the lid, that is, the insertion flap side is often lifted, so if the above-mentioned cut is provided in the connecting portion of the lid and the insertion flap, in such a case It easily cracks the perforation. Further, since the insertion flap side is weak in strength, if the cut is provided in the connecting portion between the lid and the insertion flap, the perforation is easily undesirably cracked during transportation.

  Therefore, by providing the cut on the connection portion side between the lid and the body portion, regular opening can be easily performed without undesirably cracking the perforation.

  The packaging box of the present invention is characterized in that the cut is formed by being slightly offset from the connecting portion between the lid and the body portion toward the body portion.

  According to said structure, when a cover is bent from a trunk | drum, the part between the perforations of this lid | cover will protrude slightly from a trunk | drum.

  Accordingly, the perforation can be easily separated by putting a finger on the protruding portion.

  Furthermore, in the packaging box of the present invention, the perforation increases from the body side toward the insertion flap side, and the predetermined distance increases.

  According to said structure, the space | interval of the said perforation is narrow at the trunk | drum part side, and becomes wide at the insertion flap side.

  Therefore, the perforation is difficult to break undesirably and can be easily broken at the time of regular opening.

  The packaging box of the present invention is used as a cosmetic package.

  According to said structure, since the cosmetics as a container are generally expensive, this invention with a high tampering prevention effect is effective.

  As described above, the packaging box of the present invention is formed by extending from the front end of the lid in a packaging box configured to include a rectangular tube-shaped body portion and lids provided at both opening ends of the body portion. A tongue piece is provided on the insertion flap and the surface facing the insertion flap, and the insertion flap is inserted from the opening end so that the second tongue piece on the insertion flap side gets over the first tongue piece on the opposite surface side; Thereafter, when the insertion flap is about to be pulled out from the opening end, the second tongue piece is engaged with the first tongue piece.

  Therefore, once the lid is closed, unauthorized opening can be prevented, and the second tongue piece is inserted between the first tongue piece and the surface opposed to the opening. Thus, in the first and second tongue pieces, a firm engagement structure is realized by the mutually overlapping widths, so that unauthorized opening can be prevented more reliably.

(Embodiment 1)
FIG. 1 is a development view showing a structure of a packaging box 1 according to an embodiment of the present invention. The packaging box 1 is a so-called sack box, which is a rectangular parallelepiped box generally formed by closing both open ends 17 of the rectangular tubular body 10 with lids 16 and 16a. Since the configurations related to the lids 16 and 16a on the two opening ends 17 side are substantially the same, the corresponding portions will be described with the same reference numerals. In the developed view of FIG. 1, the broken line is indicated by a one-dot chain line.

  The body portion 10 includes four wall surfaces 11 to 14 that are connected to each other to form the rectangular tube, and a gluing surface 15 that is formed extending from the side of the wall surface 14 at one end. On the surface of the gluing surface 15, for example, glue is applied to a portion of the region 151 by a sack machine, and the sack machine allows the packaging box 1 to be placed between the wall surfaces 11 to 15 from an unfolded state (before assembly). The connecting portion (boundary) is folded in a mountain and the pasting surface 15 is overlapped with the back surface of the wall surface 11 at the other end to be glued to complete the rectangular tubular body 10.

  The completed packaging box 1 is crushed (folded) into a sheet shape, a plurality of sheets are stacked and packaged, and shipped to a customer (filling destination of the contents). At the customer, the packaging box 1 is raised in a three-dimensional manner, the lids 16 and 16a, side flaps 25 to be described later, and the like are bent, and then the contents are filled and the lids 16 and 16a are closed.

  Since this is a sack box, in this packaging box 1, the lids 16, 16 a are formed to extend away from both open ends 17 of one wall surface 12 in the unfolded state, and from the wall surface 12 in the assembled state. It is bent 90 °. And in the packaging box 1 of this embodiment, the 1st tongue piece 21 extended from the opening end 17 and turned inward in the assembly state is formed in the wall surface 14 which opposes the wall surface 12 in an assembly state. On the other hand, the insertion flap 22 is formed from the tip of the lids 16 and 16a. Further, the insertion flap 22 is formed when the packaging box 1 is die-cut, and is extended from the distal end 221 side to the proximal end 222 side by cutting up and facing the wall face with the lids 16 and 16a closed. A second tongue piece 23 protruding to the 14 side is formed.

  Therefore, these first and second tongue pieces 21 and 23 constitute an engaging structure, and when the insertion flap 22 is inserted from the opening end 17 as shown in FIG. 23 gets over the first tongue piece 21, and the lids 16 and 16a are closed. Thereafter, the lids 16 and 16 a are pulled up, and the second tongue piece 23 engages with the first tongue piece 21 when the insertion flap 22 is to be pulled out from the opening end 17. Thus, once the lids 16 and 16a are closed, unauthorized opening can be prevented, and in order to prevent the opening, the second tongue 23 is provided between the first tongue 21 and the wall surface 14. As a result, the first and second tongue pieces 21 and 22 can realize a strong engagement structure with mutually overlapping widths. Thereby, unauthorized opening of the packaging box 1 can be prevented more reliably.

  Moreover, in the packaging box 1 of this embodiment, the folding piece 24 located inside from the insertion flap 22 at the time of an assembly is formed from the front-end | tip 221 of the insertion flap 22 by mountain folding. Therefore, since the second tongue piece 23 formed from the base end 222 side of the insertion flap 22 is cut and raised from the vicinity of the base end 241 of the folded piece 24, the second tongue piece 23 is assembled when the packaging box 1 is assembled. The second tongue piece 23 comes up naturally only by inserting the folded piece 24 from the insertion flap 22 and making a mountain fold. Thereby, the assembly work can be easily performed.

  Furthermore, in the packaging box 1 of this embodiment, the side flap 25 is extended from the open end 17 of at least one of the two wall surfaces 11 and 13 adjacent to the wall surface 14 (both in the example of FIG. 1). . Therefore, the lids 16 and 16a can be received from the back (inner) surface side by the side flaps 25, and the lids 16 and 16a are fitted inside even if the contents are shorter than the length of the body portion 10. Can be suppressed.

  Furthermore, in the packaging box 1 of the present embodiment, at the connecting portion 223 of the insertion flap 22 with the lids 16 and 16a, the cuts 26 are formed from the sides 224 of at least one of the insertion flaps 22 (both in the example of FIG. 1). Is formed. The cut 26 engages with the side 251 of the side flap 25 on the wall surface 14 side in the assembled state. Therefore, the engagement between the cut 26 and the side flap 25 makes it difficult to lift the lids 16 and 16a, thereby preventing unauthorized opening more reliably. The engaging portions between the cuts 26 and the side flaps 25 may be provided only on one side of the insertion flap 22, but are preferably provided on both sides as in the example of FIG.

  Moreover, in the packaging box 1 of this embodiment, the perforation 27 for opening is formed in one lid | cover 16a. Thus, it is possible to easily perform regular opening while preventing unauthorized opening. The perforations 27 may be formed in the trunk portion 10 as in Patent Document 1, but in this case, when the contents are close to the inner diameter of the trunk portion 10, it is difficult to open (sewing machine). On the other hand, the perforations 27 are formed in the lid 16a so that opening is easy.

  And the perforation 27 is a pair at a position shifted outward from the center line 28 in the width direction of the lid 16a by a predetermined distance D2, from the connecting portion 224 between the lid 16a and the trunk portion 10 (wall surface 12), A notch 29 is formed between the pair of perforations 27 formed in the connecting portion 223 between the lid 16 a and the insertion flap 22. Therefore, the central portion 161 of the lid 16a is peeled off along the perforations 27 on both sides by lifting the lid 16a from the notch 29 in the connecting portion 224 between the lid 16a and the body portion 10.

  By the way, when it is going to confirm the contents in the packaging box 1, the tip of the lid 16 a, that is, the connecting portion 223 side with the insertion flap 22 is often lifted, so the notch 29 connects the lid 16 a and the insertion flap 22. If the portion 223 is provided, in such a case, the perforation is easily cracked. Further, the insertion flap 22 side is weak in strength, and if the notch 29 is provided in the connecting portion 223 between the lid 16a and the insertion flap 22, the perforation 27 is likely to crack undesirably even during transportation. Therefore, as described above, by providing the notch 29 on the connecting portion 224 side of the lid 16a and the body portion 10 (wall surface 12), the perforation 27 is not undesirably cracked and can be properly opened. It can be carried out.

  Further, the notch 29 is formed slightly offset from the connecting portion 224 between the lid 16a and the body part 10 (wall surface 12) by a distance D3 toward the body part 10 (wall surface 12) (die cut). ing). Accordingly, when the lid 16a is bent from the trunk portion 10 (wall surface 12), the portion between the perforations 27 of the lid 16a slightly protrudes from the trunk portion 10 (wall surface 12). The perforation 27 can be easily separated by hooking the toe or the toe.

The body portion 10 may be formed in a triangular tube, a pentagonal tube, or the like, but is preferably formed in an even-numbered rectangular tube shape such as a square tube or a hexagonal tube as in the present embodiment. Accordingly, the wall surface (12 in FIG. 1) on which the lids 16 and 16a are extended and the opposite wall surface (14 in FIG. 1) can be made parallel to each other, and the assembling work for inserting the insertion flap 22 Can be easily performed. Further, the two lids 16 and 16a may not be provided on the same wall surface (12 in FIG. 1). For example, one lid 16 is provided on the opposite wall surface 14 and the first tongue piece 21 facing the lid 16 is provided. It may be provided on the wall surface 12 side.
(Embodiment 2)
FIG. 3 is a developed view showing the structure of the packaging box 3 according to another embodiment of the present invention. The packaging box 3 is similar to the packaging box 1 described above, and corresponding portions are denoted by the same reference numerals and description thereof is omitted. It should be noted that in this packaging box 1, the structure around the lid 16 on the side where the perforations 27 are not formed is different. Specifically, the side flap 25 a is formed with a pressing piece 31 that is bent 90 ° from a side on the wall surface 14 side and extends in parallel with the wall surface 14. Therefore, the width of the side flap 21a is narrowed because of the die cutting of the material (for use in the pressing piece 31).

Therefore, when the packaging box 3 is assembled, the pressing piece 31 pushes back the insertion flap 22 and the folded folded piece 24 toward the wall surface 14 side. Accordingly, the insertion flap 22 can be in close contact with the wall surface 14, and the folded piece 24 can be in close contact with the insertion flap 22 without being opened. When the object is accommodated in the body portion 10, it is possible to prevent the insertion flap 22 and the folded piece 24 from being caught as a step, and the object can be smoothly accommodated.
(Embodiment 3)
FIG. 4 is a development view showing the structure of a packaging box 4 according to still another embodiment of the present invention. The packaging box 4 is similar to the packaging boxes 1 and 3 described above. It should be noted that in this packaging box 4, the distance D2 is increased as the pair of perforations 27a in the lid 16b becomes the insertion flap 22 side from the trunk portion 10 (wall surface 12) side. is there. That is, the interval between the perforations 27a is narrow on the body 10 (wall surface 12) side and wide on the insertion flap 22 side.

Since the cut portion 29a is formed in the connecting portion 224 between the body portion 10 (wall surface 12) and the lid 16b, the perforation 27a is difficult to break undesirably and easily breaks when properly opened. can do.
(Embodiment 4)
FIG. 5 is a development view showing a structure of a packaging box 3a according to another embodiment of the present invention. The packaging box 3a is similar to the packaging box 3 described above.
