Description

本発明は、正規の開封手段によらずに不正に開封されるのが防止されている、不正開封防止機構が備えた包装箱に関するものである。   The present invention relates to a packaging box provided with a tamper-evident prevention mechanism that is prevented from being tampered with without being properly opened.

従来の不正開封防止機構を備えた包装箱は、底部が閉塞され上部に開口を有する箱本体と、箱本体の開口を閉塞する蓋体とを備えるとともに、例えば箱本体に折り曲げ可能な係止片が、蓋体に係止片を差し込み可能なスリット状の差込孔が設けられている(例えば特許文献1を参照)。係止片は、左右の端部に、折り目を介して長さが互いに同じ突片を備えており、左右の突片を折り目で折り畳んで係止片に重ね、指で押さえるなどして両突片が開かないようにすることで、差込孔へ差し込まれる。係止片が差込孔に差し込まれると、係止片の両端部の突片が、折り畳まれた状態から開いた状態となり、両突片がストッパーの機能を果たして係止片が差込孔から抜け出るのが阻止される。よって、別に設けられた正規の開封手段によらずに包装箱が不正に開封されるのが防止されている。   A packaging box having a conventional tamper-evident prevention mechanism includes a box body having a closed bottom and an opening at the top, and a lid that closes the opening of the box body, and, for example, a locking piece that can be bent to the box body. However, the slit-like insertion hole which can insert a latching piece in a cover body is provided (for example, refer patent document 1). The locking pieces are provided with protrusions with the same length at the left and right ends through folds. The left and right protrusions are folded at the folds, overlapped with the locking pieces, and pressed with fingers. By preventing the piece from opening, it is inserted into the insertion hole. When the locking piece is inserted into the insertion hole, the protruding pieces at both ends of the locking piece are opened from the folded state, both protruding pieces serve as a stopper, and the locking piece is removed from the insertion hole. It is prevented from exiting. Therefore, it is possible to prevent the packaging box from being illegally opened without using a regular opening means provided separately.

特開2010−285179号公報JP 2010-285179 A

特許文献1に記載の不正開封防止包装箱では、係止片の両端部に設けられた左右の突片の長さが短く、両突片を折り畳んだ際に、両突片の先端部が係止片の長さ方向の中心位置付近で対向する。そのため、係止片の差込孔への差し込み時に両突片が開かないようにするためには、係止片の中心位置付近において両突片の先端部をまとめて片方の手の指で押さえるか、あるいは、各突片の根元をそれぞれ片方の手の指で押さえる必要がある。しかしながら、係止片の中心位置付近を指で押さえたのでは、指が邪魔になって係止片を差込孔へ差し込みにくい。一方で、各突片の根元をそれぞれ片方の手の指で押さえた場合も係止片を差込孔へ差し込みにくい。このように、係止片の両突片の長さが短いと、係止片を差込孔へ差し込むのに手間を要し、包装箱を組み立てる作業効率が悪いという問題がある。   In the tamper-evident prevention packaging box described in Patent Document 1, the lengths of the left and right protrusions provided at both ends of the locking piece are short, and when the protrusions are folded, the tip ends of both protrusions are engaged. Opposite the center position in the length direction of the stop piece. Therefore, in order to prevent both protrusions from opening when the locking piece is inserted into the insertion hole, the tips of both protrusions are held together and pressed with the fingers of one hand near the center of the locking piece. Alternatively, it is necessary to hold the base of each protruding piece with the finger of one hand. However, if the vicinity of the center position of the locking piece is pressed with a finger, the finger becomes in the way and it is difficult to insert the locking piece into the insertion hole. On the other hand, it is difficult to insert the locking piece into the insertion hole even when the base of each protruding piece is pressed with the finger of one hand. Thus, if the length of both the protruding pieces of the locking piece is short, it takes time to insert the locking piece into the insertion hole, and there is a problem that the work efficiency for assembling the packaging box is poor.

本発明は、上記した問題に着目してなされたものであり、係止片を差込孔に差し込みやすくすることで包装箱を組み立てる作業効率を向上させた、不正開封防止機構を備える包装箱を提供することを目的とする。   The present invention has been made paying attention to the above-described problem, and a packaging box having an unauthorized opening prevention mechanism that improves the working efficiency of assembling the packaging box by making it easy to insert the locking piece into the insertion hole.

以下、本発明の実施形態について、添付図面を参照して説明する。図1〜図3は、本発明の一実施形態である包装箱1の外観構成を示している。図4は、包装箱1の展開図を示している。包装箱1は、厚紙、段ボール紙、プラスティックシートなどの材料からなり、上端部に開口20を有する箱本体2と、箱本体2の上部開口20を閉塞する蓋体3とにより構成されている。   Embodiments of the present invention will be described below with reference to the accompanying drawings. 1-3 has shown the external appearance structure of the packaging box 1 which is one Embodiment of this invention. FIG. 4 shows a development view of the packaging box 1. The packaging box 1 is made of a material such as cardboard, corrugated paper, or a plastic sheet, and includes a box body 2 having an opening 20 at an upper end and a lid 3 that closes the upper opening 20 of the box body 2.

箱本体2は、底面部21と、周面を構成する長方形状の後面部22A、前面部22B及び左右の側面部22C,22Dとが一体に設けられた角型の容器であり、上部開口20から箱本体2内に製品を収納可能である。   The box body 2 is a rectangular container in which a bottom surface portion 21, a rectangular rear surface portion 22A, a front surface portion 22B, and left and right side surface portions 22C and 22D constituting a peripheral surface are integrally provided. The product can be stored in the box body 2.

底面部21は、後面部22A、前面部22B及び各側面部22C,22Dの下端部に折り曲げ可能に一体に設けられた2種類の底面構成片23,24(図4に示す)が、巴状に互いに絡み合って底面部21が抜けないようにされたボトムロック構造が用いられている。本実施形態では、底面構成片24に連接された連結片25を隣接する底面構成片23に糊付けしたワンタッチ底構造が用いられている。ワンタッチ底構造は、包装箱1の組み立てと同時に簡単に底面部21を形成することができる。なお、底面部21は、ワンタッチ底構造に限らず、アメリカンロック構造など、その他の公知の構造を採用することもできる。   The bottom surface portion 21 has two types of bottom surface constituent pieces 23 and 24 (shown in FIG. 4) integrally provided at the lower end portions of the rear surface portion 22A, the front surface portion 22B, and the side surface portions 22C and 22D. A bottom lock structure is used that is entangled with each other so that the bottom surface portion 21 does not come off. In the present embodiment, a one-touch bottom structure is used in which the connecting piece 25 connected to the bottom surface component piece 24 is glued to the adjacent bottom surface component piece 23. The one-touch bottom structure can easily form the bottom surface portion 21 simultaneously with the assembly of the packaging box 1. The bottom surface portion 21 is not limited to the one-touch bottom structure, and other known structures such as an American lock structure can also be adopted.

後面部22Aの上端部には、蓋体3が折り曲げ可能に一体に設けられている。また、蓋体3が設けられた後面部22Aと対向する前面部22Bの上端部には、上部開口20を閉塞する蓋体3をロックして開封するのを規制する係止片4が折り曲げ可能に一体に設けられている。また、左右の側面部22C,22Dの上端部には、それぞれフラップ26が折り曲げ可能に一体に設けられている。各フラップ26は、それぞれ側面部22C,22Dに対して垂直に折り曲げられることで、箱本体2の上部開口20を塞ぐ蓋体3を支持する。   The lid 3 is integrally provided at the upper end of the rear surface portion 22A so as to be bent. In addition, the locking piece 4 that locks and opens the lid 3 that closes the upper opening 20 can be bent at the upper end portion of the front surface portion 22B that faces the rear surface portion 22A provided with the lid 3. Are integrally provided. Further, flaps 26 are integrally provided at the upper end portions of the left and right side surface portions 22C and 22D so as to be bent. Each flap 26 is bent perpendicularly to the side surface portions 22C and 22D, thereby supporting the lid 3 that closes the upper opening 20 of the box body 2.

蓋体3は、矩形状であり、箱本体2の上部開口20を塞ぐことが可能な大きさを有している。蓋体3の先端部には、差込片30が折り曲げ可能に一体に設けられており、差込片30は、蓋体3により上部開口20を閉塞する際に垂直に折り曲げられて、箱本体2の係止片4が設けられた前面部22Bの内面と対向する。蓋体3と差込片30との境目(図4の折り目14)には、左右の両側位置に、切れ込み31が設けられている。蓋体3により上部開口20を閉塞する際に、フラップ26の前面部22B側の端縁が切れ込み31に差し込まれ、差込片30の左右の端部がフラップ26の下側に回りこんでフラップ26と係合することで、蓋体3を開封しにくくなっている。   The lid 3 is rectangular and has a size capable of closing the upper opening 20 of the box body 2. An insertion piece 30 is integrally provided at the front end of the lid 3 so as to be bendable. The insertion piece 30 is bent vertically when the lid 3 closes the upper opening 20, and the box body It faces the inner surface of the front surface portion 22B provided with the two locking pieces 4. At the boundary between the lid 3 and the insertion piece 30 (fold 14 in FIG. 4), cuts 31 are provided at both the left and right positions. When closing the upper opening 20 with the lid 3, the edge of the flap 26 on the front surface 22 </ b> B side is inserted into the notch 31, and the left and right ends of the insertion piece 30 wrap around the lower side of the flap 26. By engaging with 26, it is difficult to open the lid 3.

また、蓋体3と差込片30との境目(図4の折り目14)には、中央位置に、係止片4を差し込み可能なスリット状の差込孔5が設けられている。差込孔5には、差込片30を凹状に切り欠くことで形成される切欠部50が連設されている。切欠部50は、図4に示すように、差込孔5の長さ方向の中心位置O2に設けられているが、中心位置O2よりも左右どちらかにずれた位置に設けられていてもよい。   A slit-like insertion hole 5 into which the locking piece 4 can be inserted is provided at the center of the boundary (fold 14 in FIG. 4) between the lid 3 and the insertion piece 30. The insertion hole 5 is provided with a notch 50 formed by cutting the insertion piece 30 into a concave shape. As shown in FIG. 4, the notch 50 is provided at the center position O2 in the length direction of the insertion hole 5, but may be provided at a position shifted to the left or right of the center position O2. .

係止片4が設けられた前面部22B(箱本体2)は、上端部から下方に係止片4の左右の両端部に沿って一対の切れ込み7が設けられることで、両切れ込み7の間に支持片8を有している。支持片8は、前面部22B(箱本体2)に対して内外に屈曲可能であり、支持片8の上端部に係止片4が折り曲げ可能に一体に設けられている。係止片4を差込孔5に差し込む際に、支持片8を外側に倒すことで、係止片4を差込孔5に差し込みやすくなる。   The front surface portion 22B (box body 2) provided with the locking piece 4 is provided with a pair of cuts 7 along the left and right ends of the locking piece 4 downward from the upper end portion. The support piece 8 is provided. The support piece 8 can be bent inward and outward with respect to the front surface portion 22B (box body 2), and the locking piece 4 is integrally provided at the upper end portion of the support piece 8 so as to be bent. When the locking piece 4 is inserted into the insertion hole 5, the locking piece 4 can be easily inserted into the insertion hole 5 by tilting the support piece 8 outward.

両切れ込み7の下端部の間には、前面部22B(箱本体2)の上端部と平行なミシン目9が設けられており、ミシン目9の破断により、支持片8及び係止片4が前面部22B(箱本体2)から切り離し可能である。前面部22B(箱本体2)の上端部からミシン目9までの長さDとしては、10mm以上であることが好ましく、10mm〜35mm程度がより好ましく、20mm程度がさらに好ましい。ミシン目9が上方に位置し過ぎると、詳細は後述するが、支持片8を押し込んでミシン目9を破断させるときに、力をかけづらいからである。ミシン目9は、切断部分と非切断部分とが一定間隔で交互に連続して並んでいるが、本実施形態では、図2に示すように、中央の切断部分90Aが他の切断部分90Bよりも長さが長く設定されている。なお、ミシン目の形状は必ずしも本実施形態のものに限られるものではなく、同じ長さの切断部分が一定間隔で並んでいてもよい。   A perforation 9 parallel to the upper end of the front surface portion 22B (box body 2) is provided between the lower ends of both cuts 7, and the support piece 8 and the locking piece 4 are separated by the breakage of the perforation 9. It can be separated from the front surface portion 22B (box body 2). The length D from the upper end portion of the front surface portion 22B (box body 2) to the perforation 9 is preferably 10 mm or more, more preferably about 10 mm to 35 mm, and further preferably about 20 mm. If the perforation 9 is positioned too high, the details will be described later, but it is difficult to apply a force when the support piece 8 is pushed in and the perforation 9 is broken. In the perforation 9, the cut portions and the non-cut portions are alternately and continuously arranged at regular intervals, but in this embodiment, as shown in FIG. 2, the central cut portion 90A is more than the other cut portions 90B. Even the length is set longer. Note that the shape of the perforation is not necessarily limited to that of the present embodiment, and cut portions having the same length may be arranged at regular intervals.

支持片8の両端部と前面部22B(箱本体2)との間(両切れ込み7)には、両者を接合する1又は複数の接合部80が設けられており、包装箱1の組み立てを行う前は、支持片8は前面部22B(箱本体2)と一体となっている。前面部22B(箱本体2)の上端部の支持片8の両端部との境目となる2つの角部27は面取りされている。   Between the both end portions of the support piece 8 and the front surface portion 22B (box body 2) (both slits 7), one or a plurality of joint portions 80 for joining the two are provided, and the packaging box 1 is assembled. Before, the support piece 8 is united with the front part 22B (box main body 2). The two corners 27 that are the boundary between the upper end portion of the front surface portion 22B (box body 2) and both end portions of the support piece 8 are chamfered.

係止片4の左右の端部には、左右両側に突き出る一対の突片6が折り曲げ可能に一体に設けられている。係止片4は、図3に示すように、左右の突片6を折り畳んで係止片4に重ね、指で摘んで押さえるなどして係止片4及び両突片6が重ねられた状態を保持したまま蓋体3の差込孔5へ差し込むことで、差込孔5に差し込み可能となり、係止片4が差込孔5に差し込まれた後は、図7に示すように、左右の突片6が折り畳まれた状態から自然に開いた状態となることで、両突片6がストッパーの機能を果たして差込孔5から抜け出るのが不可能となる。   A pair of projecting pieces 6 projecting to the left and right sides are integrally provided at the left and right ends of the locking piece 4 so as to be bendable. As shown in FIG. 3, the locking piece 4 is a state in which the left and right protruding pieces 6 are folded and overlapped with the locking piece 4, and the holding piece 4 and both protruding pieces 6 are overlapped by picking and holding the fingers. 7 is inserted into the insertion hole 5 of the lid 3 so that it can be inserted into the insertion hole 5. After the locking piece 4 is inserted into the insertion hole 5, as shown in FIG. Since the protruding pieces 6 are naturally opened from the folded state, the protruding pieces 6 function as stoppers and cannot be removed from the insertion holes 5.

一対の突片6は、係止片4の左右の端部(図4の折り目15A,15B)から左右両側に突き出る長さd1が互いに同じである。さらに、一対の突片6は、図5に示すように、係止片4に折り重ねたとき、先端部が係止片4の長さ方向の中心位置O1を越えるようにその長さd1が設定されている。これにより、両突片6を係止片4にそれぞれ折り重ねると、一方の突片6の上側に他方の突片6が積み重ねられた状態となり、上側の突片6の先端部が、上記した中心位置O1よりも、下側の突片6側にずれた位置まで延出するようになる。突片6の長さd1としては、5mm以上であることが好ましく、5mm〜30mm程度がより好ましい。   The pair of protruding pieces 6 have the same length d1 protruding from the left and right ends (folds 15A and 15B in FIG. 4) of the locking piece 4 to the left and right sides. Further, as shown in FIG. 5, the pair of projecting pieces 6 has a length d1 such that when the folding pieces 6 are folded over the locking pieces 4, the tip ends exceed the center position O1 in the length direction of the locking pieces 4. Is set. As a result, when both the projecting pieces 6 are folded on the locking piece 4, the other projecting piece 6 is stacked on the upper side of the one projecting piece 6, and the tip of the upper projecting piece 6 is as described above. It extends to a position shifted to the lower protruding piece 6 side from the center position O1. The length d1 of the protruding piece 6 is preferably 5 mm or more, and more preferably about 5 mm to 30 mm.

また、一対の突片6は、その幅w1が係止片4の幅wよりも短く設定されており、突片6の前面部22B(箱本体2)側の端縁が係止片4の前面部22B(箱本体2)側の端縁(図4の折り目13B)と段差をなしていることで、前面部22B(箱本体2)側に隙間Sがあくようにして、係止片4の端部に設けられている。   The pair of projecting pieces 6 has a width w1 set shorter than the width w of the locking piece 4, and the edge of the projecting piece 6 on the front surface portion 22 </ b> B (box body 2) side is the locking piece 4. Since the front edge portion 22B (box main body 2) side edge (fold 13B in FIG. 4) is stepped, the front surface 22B (box main body 2) side has a clearance S, and the locking piece 4 Is provided at the end.

また、一対の突片6の長さd1は、蓋体3の差込片30の蓋体3の先端部(図4の折り目14)から突き出る長さdの1/2以上となるように設定されており、差込片30の長さdよりも長くてもよい。その理由については後述する。   Further, the length d1 of the pair of projecting pieces 6 is set to be ½ or more of the length d protruding from the distal end portion (fold 14 in FIG. 4) of the insertion piece 30 of the lid 3. It may be longer than the length d of the insertion piece 30. The reason will be described later.

なお、本実施形態では、差込片30の長さdが前面部22B(箱本体2)の上端部からミシン目9までの長さDとほぼ同じ長さに設定されているが、どちらか一方が他方よりも長さが長く設定されていてもよい。差込片30の長さdとしては、10mm以上であることが好ましく、10mm〜35mm程度がより好ましい。   In the present embodiment, the length d of the insertion piece 30 is set to be substantially the same as the length D from the upper end portion of the front surface portion 22B (box body 2) to the perforation 9, but either One may be set longer than the other. The length d of the insertion piece 30 is preferably 10 mm or more, and more preferably about 10 mm to 35 mm.

The lid 3, the locking piece 4, and the flaps 26 are connected in sequence. The insertion piece 30 is connected to the front end of the lid 3 via the fold line 14, and the protruding piece 6 is connected to the left and right ends of the locking piece 4 via the fold lines 15 </ b> A and 15 </ b> B. .

上記構成の包装箱1は、まず、図4に示す型紙10を用い、後面部22A、前面部22B及び各側面部22C,22Dと、底面構成片23,24とを所定の折り目に沿って折り曲げ、貼付片28や連結片25を、側面部22Cや底面構成片23に糊付けなどすることで箱本体2を組み立てる。そして、箱本体2内に製品を収納した後、蓋体3で箱本体2の上部開口20を閉塞し、係止片4にて蓋体3をロックする。蓋体3のロックは、図3に示すように、係止片4に連設された左右の突片6を係止片4に折り重ね、指で摘むなどして両突片6が重ねられた状態で係止片4を蓋体3の差込孔5へ差し込む。係止片4が差込孔5に差し込まれると、左右の突片6が折り畳まれた状態から自然にハの字状に開いた状態となり、両突片6が差込片30さらには前面部22Bに突き当たってストッパーの機能を果たすことで、係止片4が差込孔5から抜け出るのが阻止される。よって、蓋体3により箱本体2の上部開口20を閉塞した状態が保たれるので、包装箱1が不正に開封されるのを防止できる。   The packaging box 1 having the above configuration first uses the pattern 10 shown in FIG. 4 to bend the rear surface portion 22A, the front surface portion 22B, the side surface portions 22C and 22D, and the bottom surface component pieces 23 and 24 along a predetermined fold. The box body 2 is assembled by gluing the sticking piece 28 or the connecting piece 25 to the side surface portion 22C or the bottom surface constituting piece 23. After the product is stored in the box body 2, the lid body 3 closes the upper opening 20 of the box body 2, and the locking piece 4 locks the lid body 3. As shown in FIG. 3, the lid 3 is locked by folding the left and right protrusions 6 connected to the locking piece 4 onto the locking piece 4 and picking them up with fingers. In this state, the locking piece 4 is inserted into the insertion hole 5 of the lid 3. When the locking piece 4 is inserted into the insertion hole 5, the left and right protruding pieces 6 are naturally opened from a folded state into a C-shape, and both protruding pieces 6 are inserted into the inserting piece 30 and the front portion. The stopper piece 4 is prevented from coming out of the insertion hole 5 by hitting 22B and serving as a stopper. Therefore, since the state which obstruct | occluded the upper opening 20 of the box main body 2 with the cover body 3 is maintained, it can prevent that the packaging box 1 is unseal | opened.

一方で、包装箱1を開封するには、図6に示すように、係止片4を差込孔5に差し込んだまま、係止片4が設けられた前面部22Bの支持片8を指などで押し込み、ミシン目9を破断して支持片8及び係止片4を前面部22B(箱本体2)から分離させる。これにより、蓋体3の開封が可能となるので、箱本体2内から製品を取り出すことができる。   On the other hand, in order to open the packaging box 1, as shown in FIG. 6, the supporting piece 8 of the front surface portion 22 </ b> B provided with the locking piece 4 is pointed while the locking piece 4 is inserted into the insertion hole 5. The perforation 9 is broken and the support piece 8 and the locking piece 4 are separated from the front surface portion 22B (box body 2). Thereby, since the lid 3 can be opened, the product can be taken out from the box body 2.

上記構成の包装箱1によると、係止片4の左右の端部に設けられた一対の突片6の長さd1が互い同じであるが、両突片6が係止片4に折り重ねたときに、先端部が係止片4の中心位置O1をともに越えているため、一方の突片6の上側に他方の突片6が積み重ねられた状態となる。そのため、例えば、右利きの人は、上側に積み重ねられる突片6が設けられた側の係止片4の端部から指を少しだけ延ばして係止片4を摘めば、図5に示すように、上側に積み重ねられた突片6を係止片4に折り重ねられると同時に、下側に積み重ねられた突片6も他方の突片6が覆い被さることで係止片4に折り重ねられる。また、左利きの人は、下側に積み重ねられる突片6が設けられた側の係止片4の端部から指を少しだけ延ばして係止片を摘めば、両突片6の先端部を同時に摘むことができ、両突片6をまとめて係止片4に折り重ねることができる。このように、係止片4の端部側を指で摘むようにすれば、係止片4を差込孔5に差し込む際に、指がほとんど邪魔にならず、スムーズに差し込めるようになるので、包装箱1の組み立て作業の作業効率が良好に向上する。   According to the packaging box 1 configured as described above, the lengths d1 of the pair of protruding pieces 6 provided at the left and right ends of the locking piece 4 are the same, but the protruding pieces 6 are folded over the locking piece 4. In this case, since the tip part exceeds both the center position O1 of the locking piece 4, the other protruding piece 6 is stacked on the upper side of the one protruding piece 6. Therefore, for example, if a right-handed person extends a finger slightly from the end of the locking piece 4 on the side provided with the protruding piece 6 stacked on the upper side and picks the locking piece 4, as shown in FIG. In addition, the protruding piece 6 stacked on the upper side is folded on the locking piece 4, and at the same time, the protruding piece 6 stacked on the lower side is also folded on the locking piece 4 by covering the other protruding piece 6. . Further, if a left-handed person extends a finger slightly from the end of the locking piece 4 on the side provided with the protruding piece 6 stacked on the lower side and grasps the locking piece, the tip of both protruding pieces 6 is removed. They can be picked at the same time, and both protruding pieces 6 can be folded together on the locking piece 4. In this way, if the end side of the locking piece 4 is picked with a finger, when the locking piece 4 is inserted into the insertion hole 5, the finger hardly gets in the way and can be inserted smoothly. The working efficiency of the assembly work of the packaging box 1 is improved satisfactorily.

また、上記した包装箱1内に製品を収納した状態において、包装箱1を不正に開封して製品を取り出そうとする者は、前面部22Bと蓋体3の差込片30との間に指を入れ、差込片30を内側に押し倒すことで、差込片30の内側でハの字状に開いて係止片4が差込孔5から抜け出るのを阻止している両突片6を強引に係止片4に折り重ねて係止片4を差込孔5から抜き出そうと試みることが想定される。この場合、差込片30は、図7に示すように、支持片8の両外側であって、かつ、差込片30の長さdの半分よりも上側の位置P1,P2近傍を押されることが想定される。このとき、突片6の長さd1が差込片30の長さdの1/2以上あれば、突片6の先端部は差込片30の長さdの半分よりも下側に位置し、突片6が差込片30に引っ掛かって、差込片30により押されても折り畳まれにくくなる。よって、係止片4を差込孔5から抜き出そうと試みても、突片6は、係止片4に折り重ねられることなく開いた状態が保持され、差込片30さらには前面部22Bに突き当たってストッパーの機能を果たすので、係止片4が差込孔5から抜け出るのを阻止することができる。   In addition, in a state where the product is stored in the packaging box 1 described above, a person who unsuccessfully opens the packaging box 1 and takes out the product may place a finger between the front portion 22B and the insertion piece 30 of the lid 3. By inserting and inserting the insertion piece 30 inward, the protrusions 6 that open in the shape of a letter C inside the insertion piece 30 and prevent the locking piece 4 from coming out of the insertion hole 5 are removed. It is assumed that an attempt is made to pull out the locking piece 4 from the insertion hole 5 by forcibly folding the locking piece 4. In this case, as shown in FIG. 7, the insertion piece 30 is pushed near the positions P <b> 1 and P <b> 2 on both outer sides of the support piece 8 and above the half of the length d of the insertion piece 30. It is assumed that At this time, if the length d1 of the protruding piece 6 is 1/2 or more of the length d of the insertion piece 30, the tip of the protruding piece 6 is positioned below the half of the length d of the insertion piece 30. However, even if the protruding piece 6 is caught by the insertion piece 30 and pushed by the insertion piece 30, it is difficult to be folded. Therefore, even if an attempt is made to extract the locking piece 4 from the insertion hole 5, the protruding piece 6 is maintained in an open state without being folded over the locking piece 4, and the insertion piece 30 and further the front portion Since it hits 22B and functions as a stopper, it is possible to prevent the locking piece 4 from coming out of the insertion hole 5.

また、包装箱1を正規に開封する場合は、支持片8を内側に押し込むことで、ミシン目9を破断するが、突片6が、前面部22B(箱本体2)側に隙間Sをあけるようにして係止片4の端部に設けられていることで、差込孔5に係止片4が差し込まれた後も、前面部22B(箱本体2)や差込片30との間に隙間ができる。この隙間により、包装箱1の正規開封時に支持片8を内側に押し込む時点では、支持片8の内側に存在する突片6が支持片8に引っ掛かって支持片8が内側に押し込まれるのを邪魔しないため、支持片8が内側に押し込まれやすくなっていて、ミシン目9が破断しやすくなっている。ミシン目9は一部が破断すれば、連続的に全部を破断可能とできるので、支持片8の内側に突片6が存在していても、容易にミシン目9を破断させて支持片8を前面部22B(箱本体2)から分離させることができ、包装箱1の正規開封を容易に行うことができる。なお、包装箱1の組み立て時においても、隙間Sがあることで、係止片4の差込孔5への差し込み時に、係止片4が完全に差し込まれる前に突片6が差込孔5に完全に差し込まれるので、係止片4の差し込もしやすくなっている。   When the packaging box 1 is opened normally, the perforation 9 is broken by pushing the support piece 8 inward, but the projecting piece 6 opens a gap S on the front face 22B (box body 2) side. Thus, even after the locking piece 4 is inserted into the insertion hole 5, it is provided between the front surface 22 </ b> B (box body 2) and the insertion piece 30 by being provided at the end of the locking piece 4. There is a gap. Due to this gap, when the support piece 8 is pushed inward when the packaging box 1 is normally opened, the protruding piece 6 existing inside the support piece 8 is caught by the support piece 8 and hinders the support piece 8 from being pushed inward. Therefore, the support piece 8 is easily pushed inward, and the perforation 9 is easily broken. If the perforation 9 is partially broken, the whole can be continuously broken. Therefore, even if the projecting piece 6 exists inside the support piece 8, the perforation 9 can be easily broken and the support piece 8 can be broken. Can be separated from the front surface portion 22B (box body 2), and the packaging box 1 can be opened normally. Even when the packaging box 1 is assembled, there is a gap S, so that when the locking piece 4 is inserted into the insertion hole 5, the protruding piece 6 is inserted into the insertion hole before the locking piece 4 is completely inserted. Since it is completely inserted into 5, it is easy to insert the locking piece 4.

加えて、差込片30に切欠部50が設けられていることで、差込片30は切欠部50により剛性が低下している。よって、包装箱1の正規開封時に支持片8を内側に押し込む際、支持片8の内側の差込片30も内側に押し倒されやすくなっているので、ミシン目9をさらに破断しやすくなっている。   In addition, since the notch 50 is provided in the insertion piece 30, the rigidity of the insertion piece 30 is reduced by the notch 50. Therefore, when the support piece 8 is pushed inward when the packaging box 1 is normally opened, the insertion piece 30 inside the support piece 8 is also easily pushed down inside, so that the perforation 9 is further easily broken. .

また、上記構成の包装箱1によると、支持片8を前面部22B(箱本体2)から分離可能とするミシン目9は、中央の切断部分90Aが他の切断部分90Bよりも長さが長く設定されていることで、包装箱1の正規開封時に支持片8を内側に押し込んでミシン目9を破断させる際に、ミシン目9を破断させやすくなっている。   Moreover, according to the packaging box 1 of the said structure, as for the perforation 9 which can isolate | separate the support piece 8 from the front-surface part 22B (box main body 2), 90 A of center cutting parts are longer than the other cutting part 90B. By being set, the perforation 9 can be easily broken when the support piece 8 is pushed inward to break the perforation 9 when the packaging box 1 is normally opened.

また、前面部22B(箱本体2)の上端部の支持片8との境目となる2つの角部27が面取りされていて非鋭利となっていることで、包装箱1の組立時や開封時において指などが角部27に引っ掛かることがなく、作業しやすくなっている。   In addition, when the packaging box 1 is assembled or opened, the two corners 27 that are the boundary between the front end 22B (box body 2) and the support piece 8 at the upper end are chamfered and are not sharp. In this case, a finger or the like is not caught on the corner 27, and the operation is easy.
