A first embodiment of a packaging box with a tamper-proof function of the present invention will be described below with reference to FIGS. 1 to 5. FIG. FIG. 1 shows an assembled state of a packaging box 10 of this embodiment, and the packaging box 10 is formed by assembling a single box-forming piece 12 punched out from a blank sheet made of cardboard or the like.

As shown in FIG. 2(a), the box-forming piece 12 has side plates 14, 16, 18 and 20 connected in this order. The side plates 14, 16, 18, 20 have the same length in the width direction orthogonal to the connection direction, and the side plates 16, 20 are long and substantially equal in length in the connection direction, and the side plates 14, 18 have the same length. shorter and equal to each other. The side edge of the side plate 20 is provided with a glue piece 22 that is glued to the rear surface of the side plate 14 in the assembled state. Side plates 14, 16, 18, 20 and glue strip 22 are separated by crease lines 24, 26, 28, 30, respectively.

Trapezoidal flaps 32 are separated by crease lines 34 and provided at a pair of ends of the side plates 14 in a direction perpendicular to the connecting direction of the side plates. The side plate 16 has nothing extending from a pair of edges adjacent to the crease line 34 of the side plate 14, and an opening portion 36 is provided inside one edge 16a. The opening portion 36 is a substantially rectangular portion surrounded by the central portion of the edge 16a and the breaking line 38 for opening. It is laid out in a shape that bulges out like a lever.

As shown in FIG. 2(b), the breaking line 38 for opening is a plurality of cuts 40a formed at an angle that intersects the contour 36a (virtual line) of the opening portion 36 and is arranged in parallel at an equal pitch. A first breaking portion 40 having an elongated connecting portion 40b sandwiched therebetween, and a second breaking portion 42 provided with a cut 42a, which is a cut formed along the contour 36a of the opening portion 36, A second breaking portion 42 is arranged in the central portion of the U-shape, and a pair of first breaking portions 40 are arranged at both ends thereof to surround the unsealable portion 36 . Each of the plurality of cuts 40a forming the first breaking portion 40 has a linear shape and is arranged parallel to each other.

Trapezoidal flaps 44 are separated by crease lines 46 and provided at a pair of ends of the side plates 18 in a direction perpendicular to the connecting direction of the side plates. At a pair of ends of the side plate 20 adjacent to the crease line 46 of the side plate 18, rectangular lid pieces 48 are separated by the crease line 50 and provided respectively. Further, at the end of the cover piece 48 opposite to the crease line 50 , an insertion piece 52 having both corners on the tip end thereof chamfered is provided separated by a crease line 54 . The lid piece 48 and the insertion piece 52 form a lid member of the packaging box 10 .

Next, an example of a method of assembling the packaging box 10 will be described. The box-forming piece 12 shown in FIG. 2( a ) is viewed from the front side. Hereinafter, the method of folding the box-forming piece 12 so that the front side of the box-forming piece 12 is convex is normal fold, and the folding method of the back side is convex. This is called reverse folding.

First, glue is applied to the surface of the glued piece 22 , the crease line 28 is folded forward, the crease line 24 is further folded forward, and the back surface of the side plate 14 is glued to the surface of the glued piece 22 . The packaging box 10 is now in a thin folded state and shipped in this state.

Next, in a factory or the like where the contents are accommodated and packaged, the folding lines 24, 26, 28 and 30 are each folded forward at 90 degrees to form the side plates 14, 16, 18 and 20 into a three-dimensional cylindrical body 56. . Then, in order to close the end of the cylinder 56 opposite to the unsealable portion 36, the flaps 32 and 44 are normal-folded at 90 degrees along the crease lines 34 and 46 located at this end. After that, glue 58 is applied to the surface of the insertion piece 52 at this end, and the insertion piece 52 is positively folded along the crease line 54 . Then, the cover piece 48 at this end is folded forward at 90 degrees along the crease line 50, the insertion piece 52 is inserted inside the side plate 16, and the surface of the insertion piece 52 is glued to the back surface of the side plate 16. . Since the bottom lid portion of the cylindrical body 56 is now formed, the contents are put inside from the end opening on the opposite side.

Next, in order to close the end opening containing the contents and form the canopy, the lid piece 48 is folded at 90 degrees along the crease line 50 and inserted in the same manner as when the bottom lid was formed. The piece 52 is inserted inside the side plate 16, and the front surface of the insertion piece 52 is glued to the rear surface of the opening portion 36 of the side plate 16.例文帳に追加Both ends of the cylindrical body 56 are now closed, the assembled state shown in FIG.

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

A feature of the packaging box 10 of this embodiment is that when the breaking line 38 for opening is broken, the breaking state of the first breaking portion 40 becomes extremely irregular. It is not possible to predict which part of the elongated connecting portion 40b sandwiched between the cuts 40a will break, and as shown in FIG. There are times when the site breaks, as shown in FIG. Sometimes it breaks at the part. Moreover, the broken connecting portion 40b bends and rises, or rides on the adjacent connecting portion 40b, resulting in a very messy state. Therefore, even if the package is illegally opened, a noticeable mark will definitely remain on the first breaking portion 40, and it is extremely difficult to return this to a clean state that looks like it has not been opened.

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

As described above, the tamper-proof packaging box 10 is provided with the first breaking portion 40 having a unique structure along the breaking line 38 for opening. is broken, a conspicuous trace certainly remains, and since it is extremely difficult to restore this to a clean state that looks unopened, an excellent falsification prevention effect can be obtained.

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

The first breaking line of the breaking line for opening changes the breaking state even if the layout is the same when the type, thickness, etc. of the base material of the box-forming piece 12 is changed. The layout where traces remain) also changes. Therefore, every time the base material is changed, it is practical to prepare experimental breaking lines for opening with various layouts such as the modified example above, and conduct actual breaking experiments to derive the optimum layout. For example, when the breaking line 38 for opening was experimentally produced using general cardboard and an experiment was conducted, it was found that the pitch B of the cut 40a is preferably set to 1/2 or less of the length A of the cut 40a. For example, it has been found that if the length A is 5 mm, it is preferable to set the pitch B to approximately 0.7 to 2 mm.

Next, another example of a fixing method for 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 applied so as to straddle the surface of the lid piece 48 and the surface of the opening portion 36 and not overlap the breaking line 38 for opening. fixed by wearing.

The unsealing portion 36 of the packaging box 10 and the tearing line 38 for unsealing are formed such that the unsealing portion 36 is substantially square, and the unsealing portion 36 is formed to bulge in a U-shape with the edge 16 a of the side plate 16 . The layout is such that it is surrounded by lines 38 . With this layout, both fixing by gluing and fixing by sealing tape are possible, and the same falsification prevention effect can be obtained. For example, when only gluing is used for fixing, the unsealable portion 36 may be provided so as not to overlap the edge 16a, and the layout may be such that the unsealable portion 36 is surrounded only by the breaking line 38 for unsealing.

Next, a second embodiment of the falsification-preventive packaging box of the present invention will be described with reference to FIGS. 6 and 7. FIG. Here, configurations similar to those of the above-described embodiment are denoted by the same reference numerals, and descriptions thereof are 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 forming piece 64 punched out from a blank sheet made of cardboard or the like. .

The box-shaped piece 64 is obtained by partially changing the configuration of the box-shaped piece 12 described above, and the main change is, as shown in FIG. It is characterized in that an inner face plate 66 is provided on the side, and in that an unsealing breaking line 72 having a different structure from the opening breaking line 38 is provided.

The inner plate 66 is a substantially rectangular plate extending from the side plate 16, and the length of extension is slightly shorter than 1/2 of the length of the long side of the side plate 16. As shown in FIG. The inner plate 66 is connected to the side plate 16 at portions extending from both ends of the edge 16a surrounding the opening portion 36, and is separated from the side plate 16 by a crease line 68. - 特許庁A semicircular notch 70 is provided at a position facing the central portion of the edge 16a.

As shown in FIG. 7B, the breaking line 72 for unsealing is laid out in a U-shaped bulging shape from the center of the edge 16a toward the center of the side plate 16, and is the same as the above first opening. It has a tearing portion 40 and an elongated through hole 74. The through hole 74 is arranged in the central portion of the U-shape, and a pair of first breaking portions 40 are arranged at both ends thereof to surround the opening portion 36. As shown in FIG. A through hole 74 is provided to form a knob 76 at the end of the opening portion 36 . The notch 74a is a part of the through-hole 74 (both ends of the through-hole 74), and is provided as an aid to smoothly connect the through-hole 74 and the first breaking portion 40 to each other.

Next, an example of a method for assembling the packaging box 62 will be described. The box-forming piece 64 shown in FIG. 7(a) is viewed from the front side. Here, the folding method in which the front surface side is convex is called normal folding, and the folding method in which the rear surface side is convex is called reverse folding.

First, glue 78 is applied to the back surface of the tip of the inner plate 66 , the folding line 68 is folded forward, and the back surface of the inner plate 66 is glued to the back surface of the side plate 16 . Thus, the inner plate 66 overlaps the unsealing portion 36 and the breaking line 72 for opening to close the through hole 74, and the tip portion is fixed at the central portion of the side plate 16 at a position not interfering with the breaking line 72 for opening. be.

Thereafter, glue is applied to the surface of the glued piece 22 , the crease line 28 is folded forward, the crease line 24 is folded forward, and the back surface of the side plate 14 is glued to the surface of the glued piece 22 . The packaging box 62 is now in a thin folded state and shipped in this state.

Next, in a factory or the like where the contents are accommodated and packaged, the folding lines 24, 26, 28 and 30 are each folded forward at 90 degrees to form the side plates 14, 16, 18 and 20 into a three-dimensional cylindrical body 56. . Then, in order to close the end of the cylinder 56 opposite to the unsealable portion 36, the flaps 32 and 44 are normal-folded at 90 degrees along the crease lines 34 and 46 located at this end. After that, the insertion piece 52 at this end is folded forward along the crease line 54, the cover piece 48 is folded forward at 90 degrees along the crease line 50, and the insertion piece 52 is inserted inside the side plate 16 and locked. Let Then, the sealing tape 60 is stuck so as to straddle the surface of the lid piece 48 and the surface of the side plate 16 . Since the bottom lid portion of the cylindrical body 56 is now formed, the contents are put inside from the end opening on the opposite side.

Then, in order to close the end opening containing the contents, the same operation as when forming the bottom cover is performed again on this end. At this time, the sealing tape 60 is adhered so as to straddle the surface of the lid piece 48 and the surface of the unsealing portion 36 and not overlap the breaking line 72 for unsealing. Both ends of the barrel 56 are now closed and in the assembled condition shown in FIG.

When the packaging box 62 is to be unsealed, the opening 74 is used to pinch the handle 76 of the unsealable portion 36 with fingers, and the unsealable portion 36 is pulled up to open the first tearing portion 40 of the tearing line 72 for unsealing. break the When the opening portion 36 is completely separated from the side plate 16, the lid piece 48 can be opened.

When the first breaking portion 40 is broken, the breaking state becomes irregular and disorderly as described above. Therefore, even if the package is illegally opened, a noticeable mark will definitely remain on the first breaking portion 40, and it is extremely difficult to return this to a clean state that looks like it has not been opened.

When resealing, the lid piece 48 should be closed and the insertion piece 52 should be locked inside the inner plate 66 . In this state, the corners where the lid piece 48 and the insertion piece 52 intersect are exposed from the notch 70, so when the lid piece 48 is opened next time, if you put your finger on this exposed part, the lid piece 48 can be easily opened. Since the unsealing 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 packaging box 62 with a tamper-proof function, the same effects as those of the packaging box 10 can be obtained. In addition, since the opening portion 36 of the packaging box 62 is provided with a knob portion 76, the opening operation is easy. Also, the through hole 74 forming the knob 76 is open to the side plate 16, but since the through hole 74 is closed by the inner plate 66 in the assembled state, dirt and dust can enter through the through hole 74. Don't worry.

In addition, the packaging box with a tamper-proof function of the present invention is not limited to the above-described embodiments. For example, the cut structure may be intermittent cuts, perforated lines, or any other structure that can be continuously broken with a constant force. Further, the cuts are preferably provided at equal pitches, but may be provided at irregular pitches.

Also, the structure of the lid can be changed within the range in which the intended operation of the present invention is possible. In the packaging boxes 10 and 62 described above, the cover member is composed of the cover piece 48 and the insertion piece 52 extending from the tip of the cover member. It is continuous and has a structure in which a specific portion of the lid member is fixed to the opening portion 36 by a method such as gluing to form a lid portion in an assembled state. This shows an example of the structure of the lid, and for example, it is possible to change the structure of the lid 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-forming piece, the base end of one of the lid pieces is connected to the end of the unsealable portion 36 (portion of the edge 16a). and in the assembled state, the two lid pieces are weighted and glued together to form the lid. A similar effect can be obtained by changing the lid portion to a seal end type.

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.
