Description

本考案は、蓋部を封止する係止片が設けられた開封防止機能付き包装箱に関する。   The present invention relates to a packaging box with an opening prevention function provided with a locking piece for sealing a lid.

従来、例えば特許文献１に開示されているように、筒体の一方の端部を閉鎖する蓋片を不正に開封できないようにするため、蓋片に係止片を係合させて封止する未開封カートンがあった。この未開封カートンは、筒体の中の一側面である後面板の端部に蓋片が延設され、蓋片の先端部に、前面板の内側に差し込まれる差し込み片が延設され、蓋片の差し込み片寄りの位置にコの字状の差込口（挿入孔）が形成されている。後面板に対向する前面板の端部には、筒体の端部を閉鎖する蓋片の差込口に係入される係止片（舌状フック片）が延設されている。そして、前面板には、係止片の付け根から前面板の中央方向に延びる一対の切り込み（２本の切れ線）が形成され、前面板の端部から、一対の切り込みに挟まれた領域とその周縁部を囲むようにＵ字状の開封用破断線（ミシン目線）が形成され、凸状の開封部が設けられている。   Conventionally, as disclosed in, for example, Patent Document 1, in order to prevent unauthorized opening of a lid piece that closes one end of a cylinder, the lid piece is engaged with a locking piece and sealed. There was an unopened carton. In this unopened carton, a lid piece is extended at the end of the rear plate, which is one side of the cylinder, and an insertion piece to be inserted inside the front plate is extended at the tip of the lid piece. A U-shaped insertion port (insertion hole) is formed at a position closer to the insertion piece. At the end portion of the front plate facing the rear plate, a locking piece (tongue-like hook piece) that is engaged with the insertion port of the lid piece that closes the end portion of the cylinder is extended. The front plate is formed with a pair of cuts (two cut lines) extending in the center direction of the front plate from the base of the locking piece, and an area sandwiched between the pair of cuts from the end of the front plate; A U-shaped opening breaking line (perforation line) is formed so as to surround the peripheral edge portion, and a convex opening portion is provided.

一対の切り込みは、係止片を差込口に係入する時、一度外側に引き出して差し込みやすくするために設けられ、開封用破断線は、正規に開封する時、開封部及び係止片を前面板から切離させて蓋片の封止を解除するために設けられている。   A pair of cuts are provided to make it easier to pull out and insert the locking piece once into the insertion slot, and the breaking line for opening is used when the opening and the locking piece are properly opened. It is provided to release the lid piece from the front plate.

特開２０１２−１８８１３５号公報JP 2012-188135 A

十分な開封防止効果を得るためには、係止片が差込口から簡単に引き抜かれないように、係止片が差込口にしっかり係合していることが重要になる。   In order to obtain a sufficient opening prevention effect, it is important that the locking piece is firmly engaged with the insertion port so that the locking piece is not easily pulled out from the insertion port.

特許文献１の未開封カートンの場合、係止片と差込口の係合の強さは、差込口（挿入孔）のコの字形状と係止片（舌状フック片）の輪郭形状との微妙な関係によって決定される。しかしながら、組立作業者が係止片を差込口に差し込む時、係止片と差込口が互いに擦れたりぶつかったりするので、係止片や差込口の形状が微妙に変形して係合の強さが低下してしまう可能性がある。したがって、組み立て時に多少の作業ばらつきがあっても係止片と差込口の係合の強さが十分に確保されるように改善することが求められていた。   In the case of the unopened carton of Patent Document 1, the engagement strength between the locking piece and the insertion port is the U-shape of the insertion port (insertion hole) and the contour shape of the locking piece (tongue-like hook piece). And is determined by a delicate relationship. However, when the assembly operator inserts the locking piece into the insertion slot, the locking piece and the insertion slot rub against each other or collide with each other. The strength of the may decrease. Accordingly, there has been a demand for improvement so that the engagement strength between the locking piece and the insertion port is sufficiently ensured even if there is some work variation during assembly.

次に、商品等を包装する工場等において立体的に組み立てる。まず、折罫線２２，２４，２６，３０を各々９０度に正折りする。この操作によって、４つの側面板１４，１６，１８，２０が四角形の筒体３２になり、第一の側面板１４と第二の側面板１８が互いに対向する。また、糊付部４４ａと底片５４とが糊付けされ、糊付部７２ａと底片８２とが糊付けされているので、この操作によって、逆折されている折罫線４８，７６が自動的に開き、折罫線４６，５６，７４，８４が自動的に９０度に正折りされ、４つの底片４４，５４，７２，８２が倒れて重なり合い、ワンタッチ型の底面９２が形成される。これで、図３（ａ）に示す状態になる。   Next, it is assembled three-dimensionally in a factory or the like for packaging products. First, the crease lines 22, 24, 26, and 30 are each normally folded at 90 degrees. By this operation, the four side plates 14, 16, 18, 20 become a rectangular cylinder 32, and the first side plate 14 and the second side plate 18 face each other. Further, since the glued portion 44a and the bottom piece 54 are glued, and the glued portion 72a and the bottom piece 82 are glued, the folded folding lines 48 and 76 are automatically opened and folded by this operation. The ruled lines 46, 56, 74, and 84 are automatically normally folded at 90 degrees, and the four bottom pieces 44, 54, 72, and 82 are collapsed and overlapped to form a one-touch type bottom surface 92. Thus, the state shown in FIG.

その後、蓋側の開口部から商品等を入れ、折罫線５２，８０でサイドフラップ５０，７８を９０度に正折りし、折罫線３６で蓋片３４を９０度に正折りする。そして、折罫線４０で差し込み片３８を９０度に正折りし、差し込み片３８を第二の側面板１８の内側に差し込んで開口部を閉鎖すると、図３（ｂ）に示す状態になる。この状態では、係止片５６が蓋片３４を超えて上向きに突出しており、図４（ａ）に示すように、第二の折罫線５８及びスリット６０が、差込片３８の差込口４２の近傍に位置している。また、差込口４２の突出部４２ａが上向きに起立し、差込口４０の中央部を塞ぐように突出している。   Thereafter, a product or the like is put through the opening on the lid side, the side flaps 50 and 78 are normally folded at 90 degrees along the crease lines 52 and 80, and the lid piece 34 is folded at 90 degrees along the crease line 36. Then, when the insertion piece 38 is normally folded at 90 degrees along the crease line 40 and the insertion piece 38 is inserted into the second side plate 18 to close the opening, the state shown in FIG. In this state, the locking piece 56 protrudes upward beyond the lid piece 34, and the second crease line 58 and the slit 60 are inserted into the insertion port of the insertion piece 38 as shown in FIG. 42 in the vicinity. Moreover, the protrusion part 42a of the insertion port 42 stands up, and protrudes so that the center part of the insertion port 40 may be plugged up.

次は、係止片５６を差込口４２に差し込んで蓋片３４を封止する操作を行う。まず、図４（ｂ）に示すように、引起用折罫線６６を逆折りして、一対の切り込み６４に挟まれた引起部６８を外側に倒し、第二の折罫線５８を正折りすることによって、係止片５６の先端部を差込口４２の方向に案内する。そして、図５（ａ）に示すように、係止片５６を差込口４２の中に差し入れ、奥まで差し込むと図５（ｂ）の状態になる。   Next, an operation of sealing the lid piece 34 by inserting the locking piece 56 into the insertion port 42 is performed. First, as shown in FIG. 4B, the folding line 66 for pulling is reversely folded, the pulling part 68 sandwiched between the pair of cuts 64 is tilted outward, and the second folding line 58 is forward-folded. Thus, the leading end of the locking piece 56 is guided in the direction of the insertion port 42. And as shown to Fig.5 (a), when the latching piece 56 is inserted in the insertion port 42 and it inserts to the back, it will be in the state of FIG.5 (b).

図５（ｂ）の状態で、係止片５６の基端部両側の幅広になった部分が差込口４２の両端部に係合し、さらに、差込口４２の突出部４２ａがスリット６０内に入って係合する。つまり、係止片５６と差込口４２が２重に係合する形となり、従来よりも係止片５６を引き抜くのが難しくなる。また、不正に開封するため係止片５６を無理に引き抜くと、係合している部分やその周囲が変形したり破損したりして痕跡が残るので、確実な開封防止効果が得られる。これで包装作業が終了して図６に示す組み立て状態になり、商品等が出荷される。   In the state of FIG. 5B, the widened portions on both sides of the base end portion of the locking piece 56 engage with both end portions of the insertion port 42, and the protruding portion 42 a of the insertion port 42 has the slit 60. Enter and engage. That is, the locking piece 56 and the insertion port 42 are doubly engaged, and it is difficult to pull out the locking piece 56 as compared to the conventional case. In addition, if the locking piece 56 is forcibly pulled out in order to open it illegally, the engaged part and its surroundings are deformed or damaged, leaving traces, and a reliable opening preventing effect can be obtained. Thus, the packaging operation is completed, and the assembled state shown in FIG.

開封防止機能付き包装箱１０を正規に開封する時は、第二の側面板１８の開封用透孔７０から特定部分１８ａに指を掛け、図７（ａ）に示すように特定部分１８ａを引き上げて開封用破断線６２を破断させる。これで、係止片５６及び特定部分１８ａ（引起部６８を含む）が第二の側面板１８から分離し、蓋片３４の封止が解除される。そして、蓋片３４及び差込片３８を引き上げ、サイドフラップ５０，７８を引き上げると、図７（ｂ）に示すように、箱体の蓋側が開放し、中の商品等を取り出すことができる。第二の側面板１８から分離した係止片５６及び特定部分１８ａ（引起部６８を含む）は、差込口４２に係合したまま保持される。なお、開封時に、特定部分１８ａを押圧して開封用破断線６２を破断させ、開封しても良く、開封用破断線６２はミシン線状に形成されていても良い。   When the packaging box 10 with the anti-opening function is properly opened, a finger is put on the specific part 18a from the opening through hole 70 of the second side plate 18, and the specific part 18a is pulled up as shown in FIG. 7 (a). The breaking line 62 for opening is broken. As a result, the locking piece 56 and the specific portion 18a (including the pulling portion 68) are separated from the second side plate 18, and the sealing of the lid piece 34 is released. And if the lid piece 34 and the insertion piece 38 are pulled up and the side flaps 50 and 78 are pulled up, as shown in FIG. 7 (b), the lid side of the box is opened, and the product etc. inside can be taken out. The locking piece 56 and the specific portion 18a (including the pull-up portion 68) separated from the second side plate 18 are held while being engaged with the insertion port 42. At the time of opening, the specific portion 18a may be pressed to break the opening break line 62, and the opening break line 62 may be opened. The opening break line 62 may be formed in a sewing machine line shape.

以上説明したように、開封防止機能付き包装箱１０は、構造が簡単で、従来と同様の手順で容易に組み立てることができる。そして、組み立て状態で、係止片５６と差込口４２が２重に係合し、従来よりも係止片５６を引き抜くのが難しい構造になる。したがって、組み立て時に多少の作業ばらつきがあっても係止片５６と差込口４２の係合の強さが十分に確保され、改ざん等の不正開封を確実に防止することができる。   As described above, the packaging box 10 with the unsealing prevention function has a simple structure and can be easily assembled in the same procedure as the conventional one. Then, in the assembled state, the locking piece 56 and the insertion port 42 are doubly engaged, so that it is difficult to pull out the locking piece 56 than in the prior art. Therefore, even if there is some work variation at the time of assembly, the engagement strength between the locking piece 56 and the insertion port 42 is sufficiently secured, and unauthorized opening such as tampering can be reliably prevented.
