Description

この考案は、封緘テープによって閉鎖状態に固定された蓋片が不正に開封されるのを防止する構造を備えた不正開封防止機能付き包装箱に関する。   The present invention relates to a packaging box with a tamper-evident preventing function having a structure for preventing a lid piece fixed in a closed state by a sealing tape from being tampered with.

従来、例えば特許文献１に開示されているように、背面板上端に蓋板及び差し込み片を順に連接して成る上面解放状の箱体であって、差し込み片が、蓋片の先端部のおよそ中央部に折り目を介して下方に折り曲げられた中央部舌片と、中央部舌片を左右から挟むように配置された２つの挿入片とに分割されている紙箱があった。蓋板を閉鎖する時は、２つの挿入片が正面板の内面側に挿入され、中央部舌片が正面板の外面に重なり、封緘テープが蓋板、中央舌片及び正面板に順に跨るように貼着され、蓋板が閉鎖状態に固定される。   Conventionally, as disclosed in, for example, Patent Document 1, a top-open box is formed by sequentially connecting a lid plate and an insertion piece to an upper end of a back plate, and the insertion piece is approximately the tip of the lid piece. There was a paper box divided into a central tongue piece bent downward through a crease in the central part and two insertion pieces arranged so as to sandwich the central tongue piece from the left and right. When closing the cover plate, the two insertion pieces are inserted into the inner surface of the front plate, the central tongue overlaps the outer surface of the front plate, and the sealing tape straddles the cover plate, the central tongue and the front plate in order. The lid plate is fixed in a closed state.

差し込み片が分割されていない普通の紙箱の場合、蓋板を閉鎖する時は、蓋板を倒し、差し込み片を正面板の内面側に差し込んで係止させた後、封緘テープを蓋板及び正面板に跨がるように貼着する。つまり、組み立て状態で、蓋板と正面板との隙間に封緘テープが張架される形になる。そのため、不正開封しようとする者は、蓋板と正面板との隙間にカッター刃等を差し込んで慎重に封緘テープを切断すれば、箱体に痕跡（キズや変形）を残さずに開封することができた。そして、そのまま蓋板を閉じられると、外観上、開封されたことが判別しにくく、さらに、透明なテープや糊で封緘を復元することも可能であった。   In the case of an ordinary paper box in which the insert piece is not divided, when closing the cover plate, the cover plate is turned down, the insert piece is inserted into the inner surface of the front plate and locked, and then the sealing tape is attached to the cover plate and the correct plate. Adhere so as to straddle the face plate. That is, the sealing tape is stretched in the gap between the cover plate and the front plate in the assembled state. Therefore, a person who intends to open tampering can insert a cutter blade or the like into the gap between the cover plate and the front plate and carefully cut the sealing tape to open the box without leaving any traces (scratches or deformation). I was able to. When the cover plate is closed as it is, it is difficult to determine that it has been opened, and it is also possible to restore the seal with a transparent tape or glue.

これに対して、特許文献１の紙箱の場合、蓋板を閉鎖する時、蓋板を倒し、２つの挿入片を正面板の内側へ差し込んで係止させた後、中央部舌片を正面板の外側に重ね、封緘テープを蓋板、中央舌片及び正面板に順に跨るように貼着する。つまり、組み立て状態で、蓋板と正面板との隙間に、封緘テープ及び中央部舌片が互いに重なって張架される形になる。そのため、不正開封しようとする者がカッター刃で封緘テープを切断しようとすると、中央部舌片も一緒に切り離されたり、中央部舌片の表面にキズが残ったりする。したがって、外観上、不正に開封されたことを容易に判別することができ、良好な不正開封防止効果が得られる。   On the other hand, in the case of the paper box of Patent Document 1, when closing the cover plate, the cover plate is turned down, the two insertion pieces are inserted into the inner side of the front plate and locked, and then the central tongue is attached to the front plate. The sealing tape is stuck on the outer side of the cover plate so as to straddle the lid plate, the central tongue piece and the front plate in this order. That is, in the assembled state, the sealing tape and the central tongue piece are stretched over each other in the gap between the lid plate and the front plate. Therefore, when a person who attempts to open the tampering cuts the sealing tape with the cutter blade, the central tongue piece is also cut off together, or scratches remain on the surface of the central tongue piece. Therefore, it is possible to easily determine that it has been tampered with in appearance, and a good tamper-proofing effect can be obtained.

Here, regarding the folding method of each crease line of the box-forming piece 18 shown in FIG. 2A, a folding method in which the front surface is convex is referred to as normal folding, and a folding method in which the back surface is convex is referred to as reverse folding.

まず、箱体形成片１８の折罫線３４を正折りして糊付け片２８及び第一の側面板２６を第二の側面板２２及び側面板２４に重ねる。そして、糊付け片２８の表面に糊を塗布した後、折罫線３０正折りして側面板２０を糊付け片２８に重ね、側面板２０の端部の裏面を糊付け片２８に糊付けする。箱体形成片１８はこの折り畳み状態で不正開封防止機能付き包装箱１０の製造工場等から出荷される。   First, the crease line 34 of the box-forming piece 18 is folded forward and the glue piece 28 and the first side plate 26 are overlapped with the second side plate 22 and the side plate 24. Then, after applying glue on the surface of the glue piece 28, the crease line 30 is normally folded and the side plate 20 is overlaid on the glue piece 28, and the back surface of the end of the side plate 20 is glued to the glue piece 28. The box forming piece 18 is shipped from a manufacturing factory or the like of the packaging box 10 with an unauthorized opening prevention function in this folded state.

次に、収容物の包装を行う工場等において、箱体形成片１８の折罫線３０，３２，３４，３６を各々９０度に正折りし、側面板２０，２２，２４，２６で成る四角形の筒体１２を形成する。そして、折罫線５０，５２でサイドフラップ４６，４８を各々９０度に正折りし、折罫線７８で内底片７６を９０度に正折りし、内底片７６の表面に糊を塗布した後、外底片６２を９０度に正折りして内底片７６に重ね、外底片６２の裏面を内底片７６に糊付けする。これで、筒体１２の一端部がシールエンド型の底部１６で閉鎖され、反対側の開放している端部から収容物を入れる。   Next, in a factory or the like for packaging the contents, the crease lines 30, 32, 34, and 36 of the box-shaped piece 18 are each normally folded at 90 degrees to form a rectangular shape composed of side plates 20, 22, 24, and 26. A cylindrical body 12 is formed. Then, the side flaps 46 and 48 are each normally folded at 90 degrees with the crease lines 50 and 52, the inner bottom piece 76 is normally folded at 90 degrees with the crease lines 78, and paste is applied to the surface of the inner bottom piece 76, and then the outer The bottom piece 62 is folded forward at 90 degrees and overlapped with the inner bottom piece 76, and the back surface of the outer bottom piece 62 is glued to the inner bottom piece 76. Thus, one end of the cylindrical body 12 is closed by the bottom end 16 of the seal end type, and the contents are put in from the open end on the opposite side.

収容物を入れると、次は、蓋部１４を形成する操作を行う。まず、折罫線４２，４４でサイドフラップ３８，４０を各々９０度に正折りし、その後、折罫線７２で差し込み片７０を９０度に正折りし、折罫線６８で蓋片６６を９０度に正折りし、差し込み片７０を第二の側面板２２の内面側（押圧部６０の内面側）に差し込んで係止させる。そして折罫線５６で突片５４を９０度に正折りし、突片５４を蓋片６６の表面に重ねる。突片５４を蓋片６６の表面に重ねると、突片５４の表面が凸領域７４の上面７４ａとほぼ面一になり、突片５４の先端縁が凸領域７４の端縁に沿って近接配置される。   Once the contents are inserted, the operation of forming the lid portion 14 is performed next. First, the side flaps 38 and 40 are each folded forward at 90 degrees along the crease lines 42 and 44, then the insertion piece 70 is folded forward at 90 degrees along the crease line 72, and the lid piece 66 is turned 90 degrees along the crease line 68. The insert piece 70 is inserted into the inner side of the second side plate 22 (the inner side of the pressing portion 60) and locked. Then, the projecting piece 54 is normally folded at 90 degrees along the crease line 56, and the projecting piece 54 is overlaid on the surface of the lid piece 66. When the projecting piece 54 is overlaid on the surface of the lid piece 66, the surface of the projecting piece 54 is substantially flush with the upper surface 74 a of the convex region 74, and the tip edge of the projecting piece 54 is disposed close to the edge of the convex region 74. Is done.

そして、封緘テープＦＴを、凸領域７４、突片５４、及び第二の側面板２２の押圧部６０に順に跨がるように貼着し、蓋片６６を閉鎖状態に固定すると、筒体１２の蓋部１４が形成され、図１（ａ）、（ｂ）及び図３（ａ）に示す組み立て状態になる。   Then, the sealing tape FT is attached so as to straddle the convex region 74, the projecting piece 54, and the pressing portion 60 of the second side plate 22 in this order, and the lid piece 66 is fixed in the closed state. The lid portion 14 is formed, and the assembled state shown in FIGS. 1A, 1B and 3A is obtained.

不正開封防止機能付き包装箱１０を正規に開封する時は、押圧６０を指で押して開封用破断線５８を破断させ、押圧部６０を第二の側面板２２から分離させる。これで蓋片６６が開閉可能になり、蓋片６６を引き上げた後、サイドフラップ３８，４０を引き上げると、蓋部１２が広く開放し、中の収容物を取り出すことができる。突片５４及び押圧部６０は、封緘テープＦＴで蓋片６６に接続されているのでゴミにはならない。   When the packaging box 10 with an unauthorized opening prevention function is opened normally, the pressing 60 is pressed with a finger to break the opening breaking line 58 and the pressing portion 60 is separated from the second side plate 22. Thus, the lid piece 66 can be opened and closed. When the side flaps 38 and 40 are pulled up after the lid piece 66 is lifted, the lid portion 12 is widely opened, and the contents contained therein can be taken out. Since the projecting piece 54 and the pressing portion 60 are connected to the lid piece 66 by the sealing tape FT, they do not become dust.

不正開封防止機能付き包装箱１０を開封した後、再封する時は、サイドフラップ３８，４０及び蓋片６６を順に倒し、再び差し込み片７０を第二の側面板２２の内面側に差し込んで係止させる。また、不正開封防止機能付き包装箱１０を開封した後、廃棄する時は、押圧部８２を押して解体用破断線８０ｂを破断させ、外底片６２及び内底片７６を引き上げて解体用破断線８０ａを破断させて底部１６を解体する。これで、立体的な箱体を薄く折り畳むことができ、コンパクトに廃棄することができる。   When re-sealing after opening the packaging box 10 with the tamper-evident prevention function, the side flaps 38 and 40 and the lid piece 66 are brought down in order, and the insertion piece 70 is inserted into the inner side of the second side plate 22 again. Stop. Further, when the packaging box 10 with the unauthorized opening preventing function is opened and then discarded, the pressing portion 82 is pushed to break the breaking line 80b for dismantling, and the outer bottom piece 62 and the inner bottom piece 76 are pulled up so that the breaking line 80a for dismantling is formed. The bottom 16 is disassembled by breaking. Thereby, a three-dimensional box can be folded thinly and can be discarded compactly.

不正開封防止機能付き包装箱１０は、組み立て状態で、蓋片６６と第二の側面板２２との隙間に封緘テープＦＴ及び突片５４が互いに重なって張架される形になるので、特許文献１の紙箱と同様に、良好な不正開封防止効果が得られる。また、差し込み片７０が普通の形状（分割されていない形状）なので、組み立てや再封の操作も容易である。   Since the packaging box 10 with an unauthorized opening prevention function is in an assembled state, the sealing tape FT and the projecting piece 54 are stretched over each other in the gap between the lid piece 66 and the second side plate 22. As in the case of No. 1 paper box, a good anti-tampering effect can be obtained. Moreover, since the insertion piece 70 is a normal shape (shape which is not divided | segmented), operation of an assembly or resealing is also easy.

また、蓋片６６の凸領域７４は、不正開封するのをさらに難しくしている。例えば、不正開封防止機能付き包装箱１０から凸領域７４を省略した比較例の包装箱１０ｘについて考えると、比較例の包装箱１０ｘは、図３（ｂ）に示すように、組み立て状態で、突片５４の先端縁と蓋片６６の表面との境界部に段差が発生する。したがって、作業者が封緘テープＦＴを急いで貼着した時や作業ばらつきが生じた時、封緘テープＦＴが段差のところで斜めに張架されることが考えられる。   Further, the convex region 74 of the lid piece 66 makes it more difficult to tamper open. For example, when considering the packaging box 10x of the comparative example in which the convex region 74 is omitted from the packaging box 10 with the tamper-evident prevention function, the packaging box 10x of the comparative example is in an assembled state as shown in FIG. A step is generated at the boundary between the tip edge of the piece 54 and the surface of the lid piece 66. Therefore, it is conceivable that the sealing tape FT is stretched obliquely at the level difference when the operator urgently applies the sealing tape FT or when work variation occurs.

そうすると、不正開封しようとする者は、斜めに張架された部分ＦＴａ（特に蓋片６６に近い位置）に沿って直線的にカッター刃ＣＵを入れれば、箱体に痕跡（キズや変形）を残さずに封緘テープＦＴを切断できるので、十分な不正開封防止効果が得られない可能性がある。また、封緘テープＦＴが図３（ｂ）に示す状態に保持されると、部分ＦＴａはシール性があまり低下しないので、蓋部１４が元の閉鎖状態に戻され、部分ＦＴａを蓋片６６の表面に丁寧に貼着されると、外観上、開封されたことを判別できなくなる可能性がある。   Then, if the person who tries to open the tampering inserts the cutter blade CU linearly along the portion FTa (particularly the position close to the lid piece 66) stretched obliquely, traces (scratches and deformation) will appear in the box. Since the sealing tape FT can be cut without leaving, there is a possibility that a sufficient unauthorized opening preventing effect cannot be obtained. Further, when the sealing tape FT is held in the state shown in FIG. 3B, the sealing performance of the portion FTa does not deteriorate so much, so the lid portion 14 is returned to the original closed state, and the portion FTa is removed from the lid piece 66. If it is carefully affixed to the surface, it may not be possible to determine that it has been opened.

これに対して、図３（ａ）に示す不正開封防止機能付き包装箱１０は、凸領域７４を設けることによって、部分ＦＴａのように箱体の表面から浮き上がる部分をほぼ無くすことができ、不正開封しようとする者は、カッター刃ＣＵをどのように使用しても、箱体に痕跡（キズや変形）を残さずに封緘テープＦＴを切断することは困難である。したがって、包装箱１０ｘよりも優れた不正開封防止効果が得られる。   On the other hand, the packaging box 10 with the unauthorized opening prevention function shown in FIG. 3 (a) can substantially eliminate the part that rises from the surface of the box like the part FTa by providing the convex region 74. It is difficult for a person who is trying to open the envelope to cut the sealing tape FT without leaving any trace (scratch or deformation) in the box, no matter how the cutter blade CU is used. Therefore, the tampering prevention effect superior to the packaging box 10x is obtained.

次に、本考案の不正開封防止機能付き包装箱の第二の実施形態について、図４〜図６に基づいて説明する。ここで、上記の不正開封防止機能付き包装箱１０と同様の構成は、同一の符号を付して説明を省略する。   Next, 2nd embodiment of the packaging box with an unauthorized opening prevention function of this invention is described based on FIGS. Here, the same configurations as those in the packaging box 10 with the unauthorized opening prevention function are denoted by the same reference numerals, and description thereof is omitted.

この実施形態の不正開封防止機能付き包装箱８４は、図４（ａ）、（ｂ）に示すように、筒体１２の両端が蓋部１４及び底部１６で閉鎖された直方体形状の箱体である。蓋部１４は、上記と同様の封緘テープＦＴを貼着することによって閉鎖状態に固定されている。   As shown in FIGS. 4A and 4B, the packaging box 84 with an unauthorized opening preventing function of this embodiment is a rectangular parallelepiped box body in which both ends of the cylindrical body 12 are closed by the lid portion 14 and the bottom portion 16. is there. The lid part 14 is fixed in a closed state by sticking a sealing tape FT similar to the above.

不正開封防止機能付き包装箱８４は、厚紙等で成る一枚の箱体形成片８２を組み立てることによって形成される。箱体形成片８６は、図５に示すように、上記の箱体形成片１８と類似しており、相違しているのは、突片８８の大きさ及び形状が上記の突片５４と異なっている点と、凸領域７４が省略されている点である。   The packaging box 84 with an unauthorized opening prevention function is formed by assembling a single box forming piece 82 made of cardboard or the like. As shown in FIG. 5, the box-forming piece 86 is similar to the box-forming piece 18, and the difference is that the size and shape of the protruding piece 88 is different from the protruding piece 54. And the convex region 74 is omitted.

突片８８は、第二端辺２２ａの中央部に延設され、折罫線５６で第二の側面板５６で第二の側面板２２（押圧部６０）と区切られている。突片８８の形状は略半円形であり、突片８８の延出長さは、上記の突片５４の延出長さの約半分で、幅は、封緘テープＦＴの幅よりも狭く設定されている。   The projecting piece 88 extends in the center of the second end side 22 a and is separated from the second side plate 22 (pressing portion 60) by the second side plate 56 by the crease line 56. The shape of the projecting piece 88 is substantially semicircular, the extending length of the projecting piece 88 is about half of the extending length of the projecting piece 54, and the width is set narrower than the width of the sealing tape FT. ing.

不正開封防止機能付き包装箱８４は、上記と同様の方法で組み立てることができ、組み立て状態の蓋部１４は、図６（ａ）、（ｂ）に示すように、突片８８が蓋片６６の表面側に重なるように倒れ、封緘テープＦＴが蓋片６６、突片８８、及び第二の側面板２２の押圧部６０に順に跨がるように貼着される。特徴的なのは、封緘テープＦＴが突片８８の全体を覆うように貼着される点である。   The packaging box 84 with an unauthorized opening prevention function can be assembled by the same method as described above, and the lid portion 14 in the assembled state has a projecting piece 88 as a lid piece 66 as shown in FIGS. 6 (a) and 6 (b). The sealing tape FT is stuck so as to straddle the lid piece 66, the projecting piece 88, and the pressing portion 60 of the second side plate 22 in order. What is characteristic is that the sealing tape FT is stuck so as to cover the entire protrusion 88.

不正開封防止機能付き包装箱８４は、凸領域７４を有していないので、図６（ｂ）に示すように、組み立て状態で、突片８８の先端縁と蓋片６６の表面との境界部に段差が発生する。したがって、図３（ｂ）に示す比較例の包装箱１０ｘと同様に、封緘テープＦＴが段差のところで斜めに張架されることが考えられる。そのため、不正開封しようとする者は、斜めに張架された部分ＦＴａに沿ってカッター刃ＣＵを入れれば、封緘テープＦＴを切断することができる。   Since the packaging box 84 with an unauthorized opening prevention function does not have the convex region 74, as shown in FIG. 6B, in the assembled state, the boundary between the tip edge of the projecting piece 88 and the surface of the lid piece 66 A level difference is generated. Therefore, like the packaging box 10x of the comparative example shown in FIG. 3B, it is conceivable that the sealing tape FT is stretched obliquely at the level difference. Therefore, the person who intends to open the tampering can cut the sealing tape FT by inserting the cutter blade CU along the portion FTa stretched obliquely.

上記の比較例の包装箱１０ｘの場合、カッター刃ＣＵを直線的に移動させるだけでよいので、慎重に作業を行えば、封緘テープＦＴを比較的綺麗に切断することができる。しかしながら、不正開封防止機能付き包装箱８４の場合は、半円形の突片８８全体が封緘テープＦＴに覆われているので、カッター刃ＣＵを直線的に移動させるだけでは切断できないので、作業を慎重に行ったとしても、封緘テープＦＴを綺麗に切断することは困難である。したがって、必ず不正開封したことを示す痕跡が残り、十分な不正開封防止効果が得られる。   In the case of the packaging box 10x of the above comparative example, it is only necessary to move the cutter blade CU linearly. Therefore, if the operation is performed carefully, the sealing tape FT can be cut relatively neatly. However, in the case of the packaging box 84 with the tamper-evident prevention function, since the entire semicircular protruding piece 88 is covered with the sealing tape FT, it cannot be cut only by moving the cutter blade CU linearly. However, it is difficult to clean the sealing tape FT cleanly. Therefore, there is always a trace indicating that the tampering has been opened, and a sufficient tampering prevention effect can be obtained.

このように、不正開封防止機能付き包装箱８４においても、上記の不正開封防止機能付き包装箱１０と同様の優れた効果を得ることができる。   Thus, also in the packaging box 84 with an unauthorized opening prevention function, the same excellent effect as the packaging box 10 with an unauthorized opening prevention function can be obtained.

なお、本考案の不正開封防止機能付き包装箱は、上記実施形態に限定されるものではない。例えば、第二端辺に延設される突片の形状は自由に変更することができる。上記の不正開封防止機能付き包装箱１０は、突片５４が幅広の長方形であり、先端縁が直線状になっているが、例えば先端縁を円弧形に膨出させてもよい。この場合、凸領域７４の折罫線７２側の端縁の形状を突片５４の形状に合わせて内向きに凹ませることによって、上記と同様の効果が得られる。   In addition, the packaging box with an unauthorized opening prevention function of this invention is not limited to the said embodiment. For example, the shape of the projecting piece extending on the second end side can be freely changed. In the packaging box 10 with the unauthorized opening preventing function, the protruding piece 54 is a wide rectangle and the leading edge is linear. For example, the leading edge may be bulged into an arc shape. In this case, the same effect as described above can be obtained by indenting the shape of the edge of the convex region 74 on the crease line 72 side inwardly in accordance with the shape of the protruding piece 54.

また、上記の不正開封防止機能付き包装箱８４は、突片８８が幅狭な半円形であり、先端縁が緩やかな曲線になっているが、例えば三角波状、正弦波状あるいは矩形波状のキザギザを付けてもよい。これによって、封緘テープをカッター刃で綺麗に切断するのがより困難になり、不正開封防止効果をさらに向上させることができる。また、蓋片６６に凸領域７４を付加してもよい。   In addition, the packaging box 84 with the unauthorized opening preventing function has a semi-circular shape with the protruding piece 88 and a gently curved tip edge. For example, a triangular wave, a sinusoidal wave or a rectangular wave-shaped jagged edge is used. May be attached. Accordingly, it becomes more difficult to clean the sealing tape with a cutter blade, and the effect of preventing unauthorized opening can be further improved. Further, the convex region 74 may be added to the lid piece 66.

その他、底部の構成は、上記の底部１６のようなシールエンド型に限定されず、自由に変更することができ、例えば、例えば蓋部と同じ構造にしてもよい。   In addition, the configuration of the bottom portion is not limited to the seal end type like the bottom portion 16 described above, and can be freely changed. For example, the same structure as the lid portion may be used.
