Hereinafter, the first embodiment of the packaging box with a falsification prevention function of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 shows an assembled state of the packaging box 10 of this embodiment, and the packaging box 10 is formed by assembling a single box body forming piece 12 punched from a blank sheet made of thick paper or the like.

As shown in FIG. 2A, the box body forming pieces 12 have side plates 14, 16, 18, and 20 connected in this order. The side plates 14, 16, 18 and 20 have the same length in the width direction orthogonal to the connecting direction, and the lengths in the connecting direction are almost equal to each other because the side plates 16 and 20 are long, and the side plates 14 and 18 have the same length. Shorter and equal to each other. A glue piece 22 that is glued to the back surface of the side plate 14 in an assembled state is provided on the side edge of the side plate 20. The side plates 14, 16, 18, 20 and the glued piece 22 are separated by fold ruled lines 24, 26, 28, 30, respectively.

Trapezoidal flaps 32 are provided at the pair of ends of the side plates 14 in a direction perpendicular to the connecting direction of the side plates, respectively, separated by a fold ruled line 34. The side plate 16 has nothing extended to a pair of end sides adjacent to the fold ruled line 34 of the side plate 14, and an opening portion 36 is provided inside one end side 16a. The opening portion 36 is a substantially quadrangular portion surrounded by the central portion of the end side 16a and the opening breaking line 38, and the opening breaking line 38 is directed from the central portion of the end side 16a toward the center of the side plate 16. It is laid out in a U-shaped bulge.

As shown in FIG. 2B, the opening break line 38 is formed by arranging a plurality of cuts 40a formed at an angle intersecting the contour 36a (virtual line) of the opening portion 36 at an equal pitch, and the cuts 40a. It has a first broken portion 40 having an elongated connecting portion 40b sandwiched between them, and a second broken portion 42 provided with a notch 42a formed along the contour 36a of the opening portion 36. A second fractured portion 42 is arranged at the center of the U-shape, and a pair of first fractured portions 40 are arranged at both ends thereof to surround the opening portion 36. The plurality of cuts 40a constituting the first fracture portion 40 have a linear shape and are arranged in parallel with each other.

Trapezoidal flaps 44 are provided at each of the pair of ends of the side plates 18 in a direction perpendicular to the connecting direction of the side plates, separated by a fold ruled line 46. A rectangular lid piece 48 is provided at each of the pair of ends of the side plate 20 adjacent to the fold ruled line 46 of the side plate 18, separated by the fold ruled line 50. Further, at the end of the lid piece 48 on the opposite side to the fold ruled line 50, an insertion piece 52 having both corners on the tip side chamfered roundly is provided, each separated by a fold ruled line 54. The lid piece 48 and the insertion piece 52 serve as a lid member for the packaging box 10.

Next, an example of how to assemble the packaging box 10 will be described. The box body forming piece 12 shown in FIG. 2A is viewed from the front surface side. Hereinafter, the folding method in which the front surface side of the box body forming piece 12 is convex is forward-folded, and the folding method in which the back surface side is convex is described. Called reverse folding.

First, glue is applied to the surface of the glued piece 22, the folded ruled line 28 is folded forward, the folded ruled line 24 is folded forward, and the back surface of the side plate 14 is glued to the surface of the glued piece 22. As a result, the packaging box 10 is in a thinly folded state and is shipped in this state.

Next, in a factory or the like that stores and wraps the contents, the folding ruled lines 24, 26, 28, and 30 are each folded at 90 degrees, and the side plates 14, 16, 18, and 20 are made into a three-dimensional cylinder 56. .. Then, in order to close the end portion of the tubular body 56 on the side opposite to the opening portion 36, the flaps 32 and 44 are folded forward at 90 degrees at the folding ruled lines 34 and 46 located at this end portion. After that, glue 58 is applied to the surface of the insertion piece 52 at the end portion, and the insertion piece 52 is folded forward along the fold ruled line 54. Then, the lid piece 48 at this end is folded forward at 90 degrees along the fold ruled line 50, the insertion piece 52 is inserted inside the side plate 16, and the front surface of the insertion piece 52 is glued to the back surface of the side plate 16. .. Now that the bottom lid of the tubular body 56 has been formed, the contents can be put in through the end opening on the opposite side.

Next, in order to close the end opening containing the contents to form the canopy, the lid piece 48 is folded forward at 90 degrees along the folding ruled line 50 and inserted in the same manner as when the bottom canopy is formed. The piece 52 is inserted into the inside of the side plate 16, and the front surface of the insertion piece 52 is glued to the back surface of the opening portion 36 of the side plate 16. With this, both ends of the tubular body 56 are closed, the assembled state shown in FIG. 1 is obtained, and the contents are shipped to the market together with the packaging box 10.

When opening the packaging box 10, the opening portion 36 is pressed to break the opening break line 38 surrounding the opening portion 36. Then, when the opening portion 36 is completely separated from the side plate 16, the lid piece 48 can be opened.

The feature of the packaging box 10 of this embodiment is that when the opening break line 38 is broken, the broken state of the first broken portion 40 becomes extremely irregular. The elongated joint portion 40b sandwiched between the cut portion 40a and the cut portion 40a could not predict which portion would break, and as shown in FIG. 3A, was separated from the opening portion 36 of the joint portion 40b. Sometimes the part breaks, as shown in FIG. 3C, when the part close to the opening 36 breaks, and as shown in FIG. 3B, close to the part away from the opening 36. Sometimes it breaks at the part. Further, the broken connecting portion 40b bends and stands up, or rides on the adjacent connecting portion 40b, resulting in a very messy state. Therefore, even if the package is opened illegally, a remarkable trace remains on the first broken portion 40, and it is extremely difficult to return the trace to a clean state that looks unopened.

When resealing, the lid piece 48 may be closed and the insertion piece 52 may be inserted into the side plate 16 to be locked. Since the opening portion 36 is glued to the insertion piece 52, it moves integrally with the insertion piece 52 thereafter.

As described above, since the packaging box 10 with the falsification prevention function is provided with the first breaking portion 40 having a unique structure on the opening breaking line 38, even if the opening is illegally opened, the first breaking portion 40 However, it is extremely difficult to return it to a clean state that looks unopened, so that a remarkable tamper-proof effect can be obtained.

Next, a modified example of the opening breaking line 38 provided in the packaging box 10 (opening breaking lines 38 (1) to 38 (3)) will be described. The opening break line 38 (1) shown in FIG. 4A is obtained by narrowing the pitch B of the plurality of cuts 40a of the first break portion 40 and increasing the number of cuts 40a accordingly. The opening break line 38 (2) shown in FIG. 4B is obtained by increasing the number of the first break portions 40 and the number of the second break portions 42, and arranging them alternately. The opening break line 38 (3) shown in FIG. 4 (c) is obtained by changing the angle at which the cut 40a of the first break portion 40 intersects the contour 36a of the opening portion 36. In addition, the linear cut 40a can be changed to a curved shape such as a semicircular arc shape or an S shape.

The first fractured portion of the opening fracture line changes the fractured state even if the layout is the same when the type and thickness of the base material of the box body forming piece 12 are changed, so that the optimum layout (noticeable). The layout that leaves traces) also changes. Therefore, it is practical to make prototypes of opening break lines having various layouts as in the above-mentioned modified example every time the base material is changed, and to carry out an experiment to actually break the base material to derive the optimum layout. For example, when a breaking line 38 for opening was prototyped using general cardboard and an experiment was conducted, it is preferable that the pitch B of the cut 40a is set to 1/2 or less of the length A of the cut 40a. For example, when the length A = 5 mm, it was found that it is preferable to set the pitch B = about 0.7 to 2 mm.

Next, another example of the fixing method when fixing the lid member of the packaging box 10 to the opening portion 36 will be described. In the case of the packaging box 10 shown in FIG. 1, the insertion piece 52 is fixed to the opening portion 36 by gluing. On the other hand, in the case of the packaging box 10 shown in FIG. 5, the sealing tape 60 is attached so as to straddle the surface of the lid piece 48 and the surface of the opening portion 36 and not to overlap the opening breaking line 38. It is fixed by wearing it.

The opening portion 36 and the opening break line 38 of the packaging box 10 have a substantially quadrangular opening portion 36, and the opening portion 36 is bulged in a U shape with the end side 16a of the side plate 16 for opening break. The layout is surrounded by the line 38. With this layout, both fixing with glue and fixing with sealing tape are possible, and the same tamper-proof effect can be obtained. For example, when only fixing by gluing is performed, the opening portion 36 can be provided so as not to be hung on the end side 16a, and the opening portion 36 can be surrounded only by the opening breaking line 38.

Next, a second embodiment of the tamper-proof packaging box of the present invention will be described with reference to FIGS. 6 and 7. Here, the same configurations as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 6 shows an assembled state of the packaging box 62 of this embodiment, and the packaging box 62 is formed by assembling a single box body forming piece 64 punched from a blank sheet made of cardboard or the like. ..

The box body forming piece 64 is a modification of a part of the configuration of the box body forming piece 12 described above, and the main changes are as shown in FIG. 7A, of the end side 16a of the side plate 16. An inner surface plate 66 is provided on the side surface, and an opening breaking line 72 having a structure different from that of the opening breaking line 38 is provided.

The inner surface plate 66 is a substantially quadrangular plate extended from the side plate 16, and the extended length is slightly shorter than 1/2 of the length of the long side of the side plate 16. The inner face plate 66 is connected to the side plate 16 at a portion where both ends of the end side 16a surrounding the opening portion 36 are extended, and is separated from the side plate 16 by a fold ruled line 68. Further, a semicircular notch 70 is provided at a position facing the central portion of the end side 16a.

As shown in FIG. 7B, the opening break line 72 is laid out in a U-shaped bulge from the central portion of the end side 16a toward the center of the side plate 16, and is the same as the above. It has a broken portion 40 and an elongated through hole 74, a through hole 74 is arranged in a U-shaped central portion, and a pair of first broken portions 40 are arranged at both ends thereof to surround the opening portion 36. The through hole 74 is provided at the end of the opening portion 36 to form a knob portion 76. The notch 74a is a part of the through hole 74 (both ends of the through hole 74), and is provided as an auxiliary in order to smoothly connect the through hole 74 and the first fractured portion 40.

Next, an example of how to assemble the packaging box 62 will be described. The box body forming piece 64 shown in FIG. 7A is viewed from the front surface side, and here, a folding method in which the front surface side is convex is referred to as a normal fold, and a folding method in which the back surface side is convex is referred to as a reverse fold.

First, glue 78 is applied to the back surface of the tip end portion of the inner surface plate 66, the fold ruled line 68 is folded forward, and the back surface of the inner surface plate 66 is glued to the back surface of the side plate 16. As a result, the inner surface plate 66 overlaps the opening portion 36 and the opening breaking line 72 to close the through hole 74, and the tip portion is fixed at the central portion of the side plate 16 so as not to be hooked on the opening breaking line 72. To.

After that, glue is applied to the surface of the glued piece 22 to fold the fold ruled line 28 forward, and then the fold ruled line 24 is folded forward to glue the back surface of the side plate 14 to the surface of the glued piece 22. The packaging box 62 is now in a thinly folded state and is shipped in this state.

Next, in a factory or the like that stores and wraps the contents, the folding ruled lines 24, 26, 28, and 30 are each folded at 90 degrees, and the side plates 14, 16, 18, and 20 are made into a three-dimensional cylinder 56. .. Then, in order to close the end portion of the tubular body 56 on the side opposite to the opening portion 36, the flaps 32 and 44 are folded forward at 90 degrees at the folding ruled lines 34 and 46 located at this end portion. After that, the insertion piece 52 at the end is normally folded along the fold ruled line 54, the lid piece 48 is normally folded at 90 degrees along the fold ruled line 50, and the insertion piece 52 is inserted inside the side plate 16 to lock. Let me. Then, the sealing tape 60 is attached so as to straddle the surface of the side plate 16 from the surface of the lid piece 48. Now that the bottom lid of the tubular body 56 has been formed, the contents can be put in through the end opening on the opposite side.

Next, in order to close the end opening containing the contents, the same work as when forming the bottom lid is performed again at this end. At this time, the sealing tape 60 is attached so as to extend from the surface of the lid piece 48 to the surface of the opening portion 36 and not to overlap the opening breaking line 72. This closes both ends of the cylinder 56, puts it in the assembled state shown in FIG. 6, and ships the contents together with the packaging box 62.

When opening the packaging box 62, the through hole 74 is used to pinch the knob portion 76 of the opening portion 36 with a finger, and the opening portion 36 is pulled up to perform the operation of pulling up the opening portion 36 to perform the operation of pulling up the opening portion 36 to perform the operation of pulling up the opening portion 36 to perform the operation of pulling up the opening portion 36. To break. Then, when the opening portion 36 is completely separated from the side plate 16, the lid piece 48 can be opened.

When the first broken portion 40 is broken, the broken state becomes an irregular and messy state as described above. Therefore, even if the package is opened illegally, a remarkable trace remains on the first broken portion 40, and it is extremely difficult to return the trace to a clean state that looks unopened.

When resealing, the lid piece 48 may be closed and the insertion piece 52 may be locked inside the inner surface plate 66. In this state, the corner where the lid piece 48 and the insertion piece 52 intersect is exposed from the notch 70. Therefore, when the lid piece 48 is opened next time, if a finger is put on the exposed part, the lid piece 48 can be easily opened. Since the opening portion 36 is connected to the lid piece 48 by the sealing tape 60, it moves integrally with the insertion piece 52 thereafter.

As described above, according to the tamper-proof packaging box 62, the same effect as that of the packaging box 10 can be obtained. In addition, since the packaging box 62 is provided with a knob portion 76 in the opening portion 36, the opening operation is easy. Further, the through hole 74 forming the knob portion 76 is opened in the side plate 16, but since the through hole 74 is closed by the inner surface plate 66 in the assembled state, dust and dirt enter through the through hole 74. No worries.

The packaging box with a falsification prevention function of the present invention is not limited to the above embodiment. For example, the structure of the cut may be a sewing machine wire as well as an intermittent cut, and may be a structure capable of continuously breaking with a constant force. Further, the cuts are preferably provided at equal pitches, but may be provided at unequal pitches.

Further, the structure of the lid portion can be changed within a range in which the operation intended by the present invention can be performed. In the above-mentioned packaging boxes 10 and 62, the lid member is composed of the lid piece 48 and the insertion piece 52 extending from the tip portion thereof, and the lid member is not the opening portion 36 in the state of the box body forming piece. The structure is continuous, and in the assembled state, a specific portion of the lid member is fixed to the opening portion 36 by a method such as gluing to form the lid portion. This shows an example of the structure of the lid portion, and for example, the structure of the lid portion can be changed to a seal end type. In the case of the seal end type, the lid member is composed of two lid pieces, and in the state of the box body forming piece, the base end portion of one lid piece is continuous with the end portion (the portion of the end side 16a) of the opening portion 36. In the assembled state, the two lid pieces are weighted and glued to each other so that the lid portion is formed. Even if the lid portion is changed to the seal end type in this way, the same effect can be obtained.

In addition, the size of the box, the material of the base material, the shape of each member, etc. can be changed according to the application.
