  As a mechanism for preventing unauthorized opening of the packaging box (including various camouflage operations such as tampering and removal of the contents), for example, a method of sealing the packaging box by adhering a lid portion with an adhesive, FIG. As shown in FIG. 17, there is a method of sticking a seal 95 (or a label or a sealing tape) between the lid 91 and the main body 92 of the packaging box 90. However, adhesives and seals can be removed and falsified without leaving traces by peeling off them with heat. There are also seals configured to leave traces, but they are more expensive than normal seals. In addition, when an adhesive or a seal is used, it is troublesome for the user to remove these when opening the packaging box, and it is necessary to use a tool such as a cutter knife if the user wants to remove them neatly. Moreover, when peeling these, the surface of a packaging box peels and aesthetics are also impaired. Moreover, it is necessary to prepare the seal separately from the packaging box, which increases the manufacturing cost and man-hour.

  In addition, the packaging box may be used after being re-sealed as well as when it is discarded as it is. For example, when the content is a medicine or food, the packaging box is continuously used for storing the remaining content. Regarding such resealability, the packaging boxes described in Patent Document 1 and Patent Document 2 are not considered at all. In addition, the packaging box described in any of the documents can pull out the tongue piece from the slit groove using the gap around the tongue piece or the slit groove, so that the disguise work is relatively easy.

  Also, in order to prevent trash from separating from the packaging box, and to prevent trash such as paper fragments from entering the contents as foreign matter, it is also necessary to prevent the tampering structure from being separated from the packaging box. is there. This demand is particularly strong in pharmacies and medical settings that handle large quantities of packaging boxes containing pharmaceutical products.

  This invention is made | formed in view of such a background, and it aims at providing the packaging box provided with the mechanism which prevents unauthorized opening, ensuring the function requested | required of a packaging box.

  In order to achieve the above object, one aspect of the present invention includes a first end face plate that functions as a lid, a second end face plate that faces the first end face plate, and a side face that is connected to the first end face plate. A substantially rectangular parallelepiped packaging box in which side plates to be connected are provided, and a broken piece formed in the vicinity of an edge of the side plate on the side where the first end face plate exists, and the edge on the broken piece An extension piece that is continuously provided through the insertion piece, an insertion groove that is formed along the end side in the vicinity of the boundary between the broken piece and the extension piece, and a side on which the side face plate of the first end face plate is present A continuous piece of tack, a movable piece formed in a region near the tack of the first end face plate, and a piece of the movable piece that is continuously provided on the side where the tack exists, and irreversibly in the insertion groove An insertion piece having a shape to be inserted.

  ADVANTAGE OF THE INVENTION According to this invention, the packaging box provided with the mechanism which prevents unauthorized opening, ensuring the function requested | required of a packaging box can be provided. Further, it is not necessary to prepare a seal or the like separately, and the packaging box of the present invention can be efficiently manufactured at a lower cost than the conventional packaging box. The packaging box of the present invention can be easily and reliably sealed simply by inserting the insertion piece into the insertion groove, and can be easily opened by breaking the broken piece. Also, after opening, the broken pieces and extension pieces are integrated with the plug-in pieces, and these do not separate from the packaging box, so that no dust or foreign matter is generated. There is no such thing as getting in the way. Thus, according to this invention, the packaging box provided with the tamper-evident prevention structure can be realized while ensuring the functions required in the life cycle of the packaging box. In addition, since the packaging box of this invention can be comprised from one blank, it can manufacture efficiently.

  You may make it the said insertion piece connect with the said movable piece through a broken line, for example. When a break line is formed between the insertion piece and the movable piece in this way, if the movable piece is pulled and the insertion piece is forcibly pulled out of the insertion groove, the break line will break first, and it will be inserted incorrectly. Traces of pulling out the pieces will remain in the packaging box.

  The movable piece is formed, for example, such that the surface of the movable piece and the surface of the first end face plate are flush with each other in a state where the insertion piece is inserted into the insertion groove. As described above, since the surface of the movable piece and the surface of the first end face plate are flush with each other, it becomes difficult to form a gap between them, and unauthorized opening can be reliably prevented. In addition, such a structure can be easily realized by placing the portion that becomes the movable piece on the portion that becomes the tack by the thickness of the movable piece in the blank of the packaging box.

  The insertion piece is, for example, substantially fan-shaped, and has a shape in the width direction that has a protrusion that is hooked to the end of the insertion groove when the insertion piece is inserted into the insertion groove.

  The insertion groove has, for example, cut portions that are cut in a wave shape toward the lower side of the front plate at both ends thereof. As described above, the packaging box of the present invention has a wave-shaped cut portion at both ends of the insertion groove, so it is difficult to insert a thin-walled thing such as a cutter blade into the insertion groove, and forcibly insert it. If it does, it will result in damaging a notch part and a trace will always remain in a packaging box.

  In addition, for example, a finger hook hole may be formed in a portion adjacent to the broken piece of the side plate so as to reduce the burden on the user when opening.

  In addition, the subject which this application discloses, and its solution method are clarified by the column of the form for inventing, and drawing.

  ADVANTAGE OF THE INVENTION According to this invention, the packaging box provided with the mechanism which prevents unauthorized opening, ensuring the function requested | required of a packaging box can be provided.

The bottom surface of the cylindrical body described above is configured by bending and combining.

[Unauthorized tamper-proof structure]
As shown in FIGS. 4 and 5, unauthorized opening (including various camouflage operations such as falsification and extraction of contents) is prevented near the center of the upper edge (+ z edge) of the front plate 12. As an element of the structure for this purpose (hereinafter also referred to as an unauthorized opening prevention structure), a substantially trapezoidal fracture piece 121a having a part of the upper end side of the front plate 12 as a lower base (long side) is formed. Adjacent to the upper base (short side) side of the broken piece 121a, the front plate 12 has a substantially trapezoidal finger hook hole with the upper base (short side) of the broken piece 121a as the lower base (long side). 127 is formed. The upper base (short side) of the finger hook 127 is located in the vicinity of the center of the front plate 12 and is parallel to the upper end side (+ z side end side) of the front plate 12. The total area of the broken piece 121a and the finger hook 127 is about 1/6 of the total area of the front plate 12. A break line 126 is formed at the boundary between the broken piece 121a and the front plate 12 (the oblique sides of both sides of the broken piece 121a). The upper base (short side) of the broken piece 121a has an arc shape that protrudes downward (−z side).

  Above the broken piece 121a (+ z side), a rectangular extension piece 121b is formed, which protrudes from the upper end side of the front plate 12 and is an element of an unauthorized opening prevention structure. The insertion groove 125 a is formed in parallel with the upper end side of the front plate 12, and its length is slightly shorter than the entire boundary line between the broken piece 121 a and the extension piece 121. Both ends of the insertion groove 125a are cut obliquely toward the lower side (−z side) of the front plate 12 in order to ensure ease of insertion and irreversibility of the insertion piece 153 described later. The whole 125a has a substantially trapezoidal shape.

  On the other hand, as shown in FIGS. 4 and 5, a substantially rectangular movable piece 152, which is an element of an unauthorized opening prevention structure, is formed in the vicinity of the center along the mountain fold line 36 of the first end face plate 15. The long side of the movable piece 152 is parallel to the x axis, and the short side of the movable piece 152 is parallel to the y axis. Note that the long side of the movable piece 152 on the tack 151 side extends (advances) to the tack 151 side by the thickness of the blank 5 (as will be described later, this structure causes the first time when the packaging box 10 is sealed. The one end face plate 15 and the movable piece 152 are flush with each other.)

  The two long sides of the movable piece 152 are both about ½ the length of the end side parallel to the x-axis of the first end face plate 15. Further, the two short sides of the movable piece 152 are both about 1/8 the length of the end side parallel to the y-axis of the first end face plate 15. The mode (shape, area, aspect ratio, etc.) of the movable piece 152 is not necessarily limited to that shown in FIG.

  The portions corresponding to the short sides of the movable piece 152 are all cut lines 52, while the long sides near the mountain fold line 35 of the movable piece 152 are valley fold lines 51 (or mountain fold lines). With this structure, the movable piece 152 can be turned up and down (bent) with the long side near the mountain fold line 35 as a fulcrum.

  The tack 151 is formed with an insertion piece 153 (tongue piece), which is an element of an unauthorized opening prevention structure. The insertion piece 153 is connected to the movable piece 152 in the vicinity of the center of the long side of the movable piece 152 provided on the first end face plate 15. The entire insertion piece 153 has a substantially fan shape. The width (length in the x-axis direction) of the insertion piece 153 is about ½ of the long side of the movable piece 152, and the height (length in the z-axis direction) of the insertion piece 153 is short of the movable piece 152. It is about the length of the side. In addition, the aspect (a shape, an area, an aspect ratio, etc.) of the insertion piece 153 is not necessarily limited to what is shown in the figure.

  A break line 154b is formed at the boundary between the insertion piece 153 and the movable piece 52 in parallel with the x-axis. A valley fold line 153a (may be a mountain fold line) is formed in the vicinity of the arc-shaped portion of the insertion piece 153. Both ends of the arc-shaped portion of the insertion piece 153 are cut in the center direction of the fan shape to form a convex portion 155 having a square shape (substantially triangular shape). The arcuate portion of the insertion piece 153 and the peripheral edge of the convex portion 155 form a cut line, whereby the insertion piece 153 is separated from the tack 151 except for the portion of the breaking line 154b (the insertion piece). 153 is connected to the movable piece 152 with the breaking line 154b as a neck. The length of the break line 154 b is about ½ of the length of the long side of the movable piece 52. A cut line 154a is formed at the boundary between the movable piece 51 and the tack 151 (both sides of the breaking line 154b).

[When sealed]
FIG. 6 is a view showing a state when the packaging box 10 is sealed. When sealing the packaging box 10, first, the blank 5 is raised three-dimensionally to form a box, and then the contents are loaded into the box and the first end face plate (top plate) 15 is closed to prevent unauthorized opening. Seal with. This figure shows a state in which the insertion piece 153 is about to be inserted into the insertion groove 125a during the sealing. As shown in the figure, when sealing the packaging box 10, the extension piece 121b is bent in advance along the insertion groove 125a and the breaking line 125b inside the box body, and the insertion piece 153 is inserted from its tip. The insertion piece 153 is pushed into the groove 125a to be coupled (locked) to the insertion groove 125a. In addition, after sealing, the packaging box 10 will be in the state shown in FIG.

  Here, the width of the insertion piece 153 is approximately the same as the length of the insertion groove 125a (for example, the width of the insertion piece 153 is slightly longer than the insertion groove 125a, and the insertion piece 153 is changed to the insertion groove 125a. Therefore, after inserting the insertion piece 153 into the insertion groove 125a, the convex portions 155 of the insertion piece 153 are formed at both ends of the insertion groove 125a. The insertion piece 153 cannot be easily pulled out from the insertion groove 125a (irreversible structure). Therefore, if the insertion piece 153 is forcibly pulled out from the insertion groove 125a, both ends of the insertion groove 125a, the broken piece 121a, the break line 126, etc. are broken and the packaging box 10 is damaged, and the packaging box The trace which tried to open to 10 will remain. Further, since the insertion piece 153 and the movable piece 52 are connected only through the breaking line 154b, if the movable piece 52 is lifted and the insertion piece 153 is forcibly pulled out from the insertion groove 125a, the breaking line 154b is first formed. To break. In this manner, if the insertion piece 153 is illegally pulled out from the insertion groove 125a, some trace remains in the packaging box 10, and it is reliably determined whether or not there has been unauthorized access to the packaging box 10. can do.

  As shown in FIG. 1, in the state where the insertion piece 153 is coupled to the insertion groove 125 a, there is no prominent protrusion on the surface of the packaging box 10. Further, as described above, in the state of the blank 5, the long side of the movable piece 152 on the tack 151 side is close to the tack 151 side by about the thickness of the blank 5 (has advanced to the tack 151 region). Therefore, for example, as shown in FIG. 2, in a state where the blank 5 is assembled, a portion where the movable piece 152 of the tack 151 comes into contact is recessed in the −z direction by about the thickness of the blank 5 (indicated by reference numeral 7 in FIG. 2). Part), in a state where the insertion piece 153 is coupled to the insertion groove 125a, the upper surface of the movable piece 152 and the upper surface of the first end face plate 15 are flush with each other without a step. Thus, since the packaging box 10 of this embodiment has almost no protrusions and gaps on its surface in the sealed state, unauthorized opening or camouflaging work is difficult. Further, if the insertion box 153 is pulled out by forcibly creating a gap, for example, by deforming the packaging box 10, the packaging box 10 is damaged and some trace remains in the packaging box 10. It is possible to reliably determine whether or not there has been. As described above, in the state in which the insertion piece 153 is coupled to the insertion groove 125a, there is no conspicuous protruding portion on the surface of the packaging box 10, so that the packaging box 10 has a transportability, a storage property, and an aesthetic appearance. Excellent in properties.

[When opened]
FIG. 7 is a view showing a state when the packaging box 10 is opened. As shown in the figure, when opening the packaging box 10, for example, the user inserts a finger into the finger hook 127 and pulls the broken piece 121 a toward the front side (−y side). As a result, the break line 126 is broken, and the broken piece 121 a is separated from the front plate 12 along the break line 126. Instead of pulling the broken piece 121a forward, the broken piece 121a is pushed into the inside of the packaging box 10 with a thumb or the like to break the broken line 126 so that the broken piece 121a is separated from the front plate 12. Good. Regardless of which method is used for opening, the break line 126 is always broken, and the fact that it has been opened remains as a trace in the packaging box 10.

  After separating the fracture piece 121a from the front plate 12, the user pushes the finger upward (+ z direction) as it is to open the first end plate 15 serving as a lid. Thereby, the packaging box 10 will be in the state shown in FIG. As shown in the figure, in the state where the packaging box 10 is opened, the insertion piece 153 remains inserted in the insertion groove 125a, and neither the broken piece 121a nor the extension piece 121b is separated from the insertion piece 153. The package box 10 remains as a unit. Therefore, when the packaging box 10 is opened, no dust or foreign matter is generated, and no foreign matter is mixed into the contents.

[When resealing]
When the packaging box 10 is resealed from the opened state shown in FIG. 2, the user inserts the tack 151 into the box and closes the upper opening of the box with the first end face plate 15. Thereby, the packaging box 10 will be in the state shown in FIG. It should be noted that when the packaging box 10 is opened, the unauthorized opening prevention structure (the broken piece 121a, the extension piece 121b, the insertion piece 153, etc.) is separate from the tack 151 and the movable piece 152 (first end face plate 15). Since it is integrated, the tamper-evident structure is not obstructed when resealing. In addition, since any tamper-evident prevention structure exists outside the box, the tamper-evident prevention structure does not interfere with the contents of the packaging box 10. For this reason, the user can perform the resealing operation and the opening operation without any trouble, and can use the packaging box 10 comfortably.

<Life cycle of packaging box>
Next, a series of life cycles (assembly → boxing → sealing (sealing) → opening → resealing → disassembling → disposal) of the packaging box 10 will be described with the flowchart shown in FIG.

  When assembling the packaging box 10, first, a cartoning machine or the like is used, and the four side plates of the blank 5 (first side plate 11, front plate 12, second side plate 13, and back plate 14). The connecting piece 17 is bent along the mountain fold line 31, the mountain fold line 32, the mountain fold line 33, the break line 41, and the break line 42 (S811).

  Subsequently, an adhesive (hot melt or the like) is applied to the surface of the connection piece 17, and the surface of the connection piece 17 is bonded to the first side plate 11 (S812). Note that, for example, the manufacturer of the packaging box 10 delivers the packaging box 10 to the manufacturer of the contents in this state with good transport (transport) efficiency.

  Subsequently, a blank (or box) is formed by three-dimensionally raising the blank 5 using a cartning machine (box making machine) or the like (S813).

  Subsequently, the contents of the packaging box 10 are boxed in a cylinder (S814), and the packaging box 10 is sealed (sealed) (S815).

  Thereafter, the packaging box 10 reaches the user's hand through a distribution route and the like. The user opens the packaging box 10 and takes out the contents (S816). The packaging box 10 is resealed as necessary for storage of the remaining contents (S817). After use, the packaging box 10 is disassembled (S818) and discarded (S819).

[Second Embodiment]
FIG. 9 is a perspective view showing a state of the packaging box 10 having a substantially rectangular parallelepiped shape, which is described as the second embodiment, at the time of sealing (sealing) (after sealing), and FIG. 10 is a packaging box 10 of the second embodiment. FIG. 11 is a perspective view showing a state at the time of resealing (after resealing) of the packaging box 10 of the second embodiment. Moreover, FIG. 12 is the figure which looked at the blank 5 of the packaging box 10 of 2nd Embodiment from the surface side of the packaging box 10, and FIG. 13 shows the blank 5 of the packaging box 10 of 2nd Embodiment in the said packaging box 10. It is the figure seen from the back side. Hereinafter, parts different from the first embodiment will be described.

  As shown in FIGS. 12 and 13, both ends of the insertion groove 125 a of the packaging box 10 of the second embodiment are cut obliquely (in a divergent direction) below the front plate 12 (−z side). (Hereafter, the said part is called the notch part 1251a.) And the whole insertion groove 125a exhibit a substantially trapezoid shape. And the said notch part 1251a of the insertion groove | channel 125a is formed in the waveform (or step shape, zigzag shape).

  FIG. 14 is a diagram showing a state when the packaging box 10 of the second embodiment is sealed, and FIG. 15 is a diagram showing a state when the packaging box 10 of the second embodiment is opened. Since the notch 1251a of the insertion groove 125a has a wave shape (or a staircase shape or a zigzag shape), a thin-walled object such as a blade of a cutter knife is used to remove the insertion piece 153 illegally. Even if it is to be inserted, it cannot be easily inserted, and if it is forced to insert, it results in damage to the cut portion 1251a, and some traces remain in the packaging box 10.

  Further, a portion in the vicinity of the lower end (−z side end portion) of the cut portion 1251 a of the insertion groove 125 a is a hypotenuse 1252 a bent toward the center side of the front plate 12. The hypotenuse 1252a acts to reduce resistance when the insertion piece 153 is inserted into the insertion groove 125a. Accordingly, the user can easily insert the insertion piece 153 into the insertion groove 125a.

  By the way, the above description is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the spirit thereof, and the present invention includes equivalents thereof.
