Description

本発明は、商品を梱包して配送するための不正開封防止ケースに関する。 The present invention relates to an unauthorized opening prevention case for packing and delivering a product.

従来、段ボールなどのケース内に商品を梱包して輸送途中に、何人かによって不正にケースが開封されて商品が抜き取られ、再封緘して配送されるという問題が発生していた。 Conventionally, there has been a problem that a product is packed in a case such as cardboard and the case is illegally opened by some person during the transportation, and the product is extracted, resealed and delivered.

このような問題を解消すべく、蓋フラップ及び底フラップの閉じ合わせ縁に対して交叉する切り目を設けることにより、第三者によってケースが不正に開封された場合に、ケースを封緘する接着テープを剥がした痕跡を残すことができる不正開封防止ケースが提案されている（例えば、特許文献１）。 In order to solve such a problem, an adhesive tape that seals the case when the case is illegally opened by a third party is provided by providing a cut line that intersects the closing edge of the lid flap and the bottom flap. A tamper-evident case that can leave a peeled trace has been proposed (for example, Patent Document 1).

上記［１］に記載の発明によれば、蓋フラップに連続して繋がるとともに、少なくとも蓋フラップの表面に側縁端に至る切り目が形成されてなる剥離部を蓋フラップの側縁に有し、剥離部上に接着テープが貼着されるので、接着テープを端部側から引き剥がすと、接着テープの貼着した剥離部が剥がれる。そのため、ケースが開封された痕跡が、蓋フラップの外装表面が剥がれる形で残るので、第三者によりケースが不正に開封されたことがわかるようになる。 According to the invention described in the above [1], the lid flap is continuously connected to the lid flap, and has at least a peeled portion formed on the surface of the lid flap so as to reach a side edge, on the side edge of the lid flap. Since the adhesive tape is stuck on the peeling portion, when the adhesive tape is peeled off from the end side, the peeling portion to which the adhesive tape is stuck is peeled off. Therefore, since the trace of the case being opened remains in a form in which the exterior surface of the lid flap is peeled off, it can be understood that the case has been opened illegally by a third party.

また、蓋フラップの剥離部が、少なくとも一方の蓋フラップの側縁及び他方の蓋フラップの前記側縁と対向する側縁に設けられる構成であるので、蓋フラップ側縁の左右何れから開封された場合であっても開封された痕跡を残すことが出来る。 Moreover, since the peeling part of the lid flap is provided on at least one side edge of the lid flap and the side edge opposite to the side edge of the other lid flap, the lid flap is opened from either the left or right side of the lid flap side edge. Even if it is a case, the opened trace can be left.

上記［２］に記載の発明によれば、蓋フラップの全ての側縁及び底フラップの全ての側縁に剥離部が設けられるので、蓋フラップの何れの側縁から或いは底フラップの何れの側縁から接着テープが引き剥がされた場合であっても、ケースが不正に開封された痕跡がより残り易い。 According to the invention described in [2] above, since the peeling portions are provided on all the side edges of the lid flap and all the side edges of the bottom flap, from any side edge of the lid flap or on any side of the bottom flap Even when the adhesive tape is peeled off from the edge, a trace that the case has been opened illegally is more likely to remain.

上記［３］に記載の発明によれば、剥離部が、接着テープが貼着される方向に沿って、蓋フラップの両側縁間及び底フラップの両側縁間に所定の間隔で複数設けられるので、接着テープを引き剥がす際に、ケースが不正に開封された痕跡がより残り易い。 According to the invention described in [3] above, a plurality of peeling portions are provided at predetermined intervals between both side edges of the lid flap and between both side edges of the bottom flap along the direction in which the adhesive tape is attached. When the adhesive tape is peeled off, the trace that the case has been tampered with is more likely to remain.

上記［４］に記載の発明によれば、複数の切り目を有する剥離部は、接着テープが貼着された場合に、接着テープの端部が剥離部の切り目の間に挟まれるような位置に設けられるので、接着テープで貼着されていない一方の切り目により、剥離部に接着テープで貼着されると剥離部の高さが、蓋フラップ或いは底フラップの平面高さよりも沈み、接着テープと剥離部との密着性が高まるので、接着テープを引き剥がす際に接着テープに密着した剥離部がより剥がれ易くなる。また、剥離部とともに剥離部周辺の蓋フラップの外装表面も剥がれ易くなる。 According to the invention described in [4] above, the peeling portion having a plurality of cuts is positioned so that the end of the adhesive tape is sandwiched between the cuts of the peeling portion when the adhesive tape is attached. Since it is provided, the height of the peeled part sinks below the plane height of the lid flap or the bottom flap when the adhesive tape is stuck to the peeled part by one cut not attached with the adhesive tape. Since adhesiveness with a peeling part increases, when peeling off an adhesive tape, the peeling part closely_contact | adhered to the adhesive tape becomes easier to peel off. Further, the exterior surface of the lid flap around the peeling portion is easily peeled off together with the peeling portion.

上記［５］に記載の発明によれば、剥離部が両蓋フラップ及び両底フラップを閉じ合わせた際の裏面から切り目が形成されてなるので、切り込み加工により外観（表面側）を損なうことがない。 According to the invention described in [5] above, since the cut portion is formed from the back surface when the peeling portion closes the both lid flaps and both bottom flaps, the appearance (front surface side) may be impaired by the cutting process. Absent.

また、剥離部が裏面から切り目が形成されてなるので、ケース表面側に剥離部が若干突出して形成され、貼着させる接着テープと剥離部との密着性が高まることにより、接着テープが引き剥がされる際に剥離部がより剥がれ易くなる。 In addition, since the peeled portion is formed with a cut from the back surface, the peeled portion is formed to protrude slightly on the case surface side, and the adhesive tape is peeled off by increasing the adhesion between the adhesive tape to be adhered and the peeled portion. The peeled portion is more easily peeled off when being removed.

剥離部２０には、貼着された接着テープ３０を引き剥がす方向に所定の長さ（例えば、約１５ｍｍ）の２本の切り目２０ａ，２０ｂが形成されてなり、２本の切り目２０ａ，２０ｂは、接着テープ３０を引き剥がす方向へ向かうに連れて互いに近づくように形成されている。 In the peeling portion 20, two cuts 20 a and 20 b having a predetermined length (for example, about 15 mm) are formed in a direction in which the adhered adhesive tape 30 is peeled off, and the two cuts 20 a and 20 b are Further, the adhesive tape 30 is formed so as to approach each other in the direction in which the adhesive tape 30 is peeled off.

２本の切り目２０ａ，２０ｂは、交わることはなく、蓋フラップ５，６に連続して繋がるとともに、蓋フラップ５，６の側縁端に至るように形成されている。 The two cuts 20a and 20b do not cross each other, are continuously connected to the lid flaps 5 and 6, and are formed so as to reach the side edge of the lid flaps 5 and 6.

不正開封防止ケースが封緘される際は、蓋フラップ５，６及び底フラップ９，１０の閉じ合わせ縁に接着テープ３０の中心が合わせられ、閉じ合わせ縁に貼着された接着テープ３０の両端部が、剥離部２０の中央付近に配置されるようにして蓋フラップ５，６及び底フラップ９，１０に貼着される。 When the unauthorized opening prevention case is sealed, the center of the adhesive tape 30 is aligned with the closing edges of the lid flaps 5 and 6 and the bottom flaps 9 and 10, and both ends of the adhesive tape 30 adhered to the closing edges Is attached to the lid flaps 5 and 6 and the bottom flaps 9 and 10 so as to be arranged near the center of the peeling portion 20.

剥離部２０の中心位置は、各フラップ５，６，９，１０の閉じ合わせ縁から、貼着する接着テープ３０半幅の位置に設定されるように設けられる。 The center position of the peeling part 20 is provided so that it may be set to the position of the adhesive tape 30 half width to stick from the closing edge of each flap 5,6,9,10.

第１実施形態においては、特に、接着テープ３０の端部が剥離部２０の２本の切り目２０ａ，２０ｂの間に挟まれるようにして接着テープ３０の貼着がなされることが好ましい。 In the first embodiment, in particular, it is preferable that the adhesive tape 30 is attached so that the end portion of the adhesive tape 30 is sandwiched between the two cuts 20a and 20b of the peeling portion 20.

図２の拡大図で示すように、両蓋フラップ５，６を折り付けて閉じ合わせた状態で、蓋フラップ５，６の剥離部２０の外側（蓋フラップ５，６の折り目側）の切り目２０ｂが接着テープ３０より外側に設けられる、つまり切り目２０ｂが接着テープ３０で貼着されず、剥離部２０の内側（蓋フラップ５，６の閉じ合わせ縁側）の切り目２０ａが接着テープ３０で貼着されるような位置で接着テープ３０を貼着する。 As shown in the enlarged view of FIG. 2, in a state where both lid flaps 5 and 6 are folded and closed, a cut 20b outside the peeling portion 20 of the lid flaps 5 and 6 (the fold side of the lid flaps 5 and 6). Is provided outside the adhesive tape 30, that is, the cut 20 b is not attached by the adhesive tape 30, and the cut 20 a inside the peeling portion 20 (the closing edge side of the lid flaps 5, 6) is attached by the adhesive tape 30. Adhesive tape 30 is attached at such a position.

剥離部２０の２本の切り目２０ａ，２０ｂで接着テープ３０の端部が挟まれるように接着テープ３０が貼着されることで、接着テープ３０で貼着されていない一方の切り目２０ｂによって、剥離部２０に接着テープ３０が貼着されると剥離部２０の高さが蓋フラップ６平面高さよりも沈み、剥離部２０の一部（切離片２０１）では接着テープ３０との密着性が高まるので、接着テープ３０を引き剥がす際に接着テープ３０と密着した切離片２０１（剥離部２０）とともに剥離部２０周辺の蓋フラップ６の外装表面も剥がれ易くなる。 The adhesive tape 30 is stuck so that the end of the adhesive tape 30 is sandwiched between the two cuts 20a and 20b of the peeling part 20, and the peeling is performed by the one cut 20b that is not attached by the adhesive tape 30. When the adhesive tape 30 is attached to the portion 20, the height of the peeling portion 20 sinks below the plane height of the lid flap 6, and the adhesiveness with the adhesive tape 30 is increased in a part of the peeling portion 20 (cut piece 201). Therefore, when the adhesive tape 30 is peeled off, the exterior surface of the lid flap 6 around the peeling portion 20 is easily peeled off together with the separation piece 201 (peeling portion 20) in close contact with the adhesive tape 30.

図３（ａ）に示すように、剥離部２０の一部に密着して貼着された接着テープ３０を矢印で示す引き剥がし方向に引き剥がすと、図３（ｂ）に示すように、接着テープ３０に付着した剥離部２０が接着テープ３０とともに引き剥がされるのに伴って、剥離部２０周辺の蓋フラップ５，６の外装表面が接着テープ３０の引き剥がし方向に剥がされる。 As shown in FIG. 3 (a), when the adhesive tape 30 adhered in close contact with a part of the peeling portion 20 is peeled off in the peeling direction indicated by the arrow, the adhesive tape 30 is bonded as shown in FIG. 3 (b). As the peeling part 20 attached to the tape 30 is peeled off together with the adhesive tape 30, the exterior surfaces of the lid flaps 5 and 6 around the peeling part 20 are peeled off in the peeling direction of the adhesive tape 30.

ここでは、説明の便宜上、蓋フラップ５，６に設けられた剥離部２０に限定して説明したが、底フラップ９，１０に設けられた剥離部２０についての構成、効果などは、蓋フラップ５，６の剥離部２０と全く同様のものである。従って、底フラップ９，１０に設けられる剥離部２０の構成、効果などについては、「蓋フラップ５，６」を「底フラップ９，１０」と読み替えて足るものとして説明は省略する。 Here, for convenience of explanation, the description is limited to the peeling portion 20 provided on the lid flaps 5 and 6, but the configuration, effects, and the like of the peeling portion 20 provided on the bottom flaps 9 and 10 are as follows. , 6 is exactly the same as the peeling portion 20 of FIG. Therefore, the configuration and effects of the peeling portion 20 provided on the bottom flaps 9 and 10 are omitted because “lid flaps 5 and 6” can be replaced with “bottom flaps 9 and 10”.

蓋フラップ５，６及び底フラップ９，１０の切り目２０ａ，２０ｂは、両蓋フラップ５，６及び両底フラップ９，１０を閉じ合わせた際の裏面から刃を突き刺すなどすることで形成される。 The cuts 20a and 20b of the lid flaps 5 and 6 and the bottom flaps 9 and 10 are formed by piercing a blade from the back surface when the lid flaps 5 and 6 and the bottom flaps 9 and 10 are closed.

このように、剥離部２０が両蓋フラップ５，６及び両底フラップ９，１０を閉じ合わせた際の裏面から切り目２０ａ，２０ｂが形成されてなるので、切り込み加工により外観（表面側）を損なうことがない上に、蓋フラップ５，６及び底フラップ９，１０の裏面に刃を突き刺すなどして、剥離部２０を容易に形成することが出来る。 As described above, the cuts 20a and 20b are formed from the back surface when the peeling portion 20 closes the lid flaps 5 and 6 and the bottom flaps 9 and 10, and the appearance (surface side) is damaged by the cutting process. In addition, the peeling portion 20 can be easily formed by inserting a blade into the back surfaces of the lid flaps 5 and 6 and the bottom flaps 9 and 10.

また、剥離部２０が裏面から切り目２０ａ，２０ｂが形成されてなるので、ケース表面側に剥離部２０が若干突出して形成され、貼着させる接着テープ３０と剥離部２０との密着性が高まることにより、接着テープ３０が引き剥がされる際に剥離部２０がより剥がれ易くなる。 Moreover, since the peeling part 20 is formed with the cuts 20a and 20b from the back surface, the peeling part 20 is slightly protruded and formed on the case surface side, and the adhesion between the adhesive tape 30 to be adhered and the peeling part 20 is increased. Thereby, when the adhesive tape 30 is peeled off, the peeling part 20 becomes easier to peel off.

上述したように第１実施形態に係る不正開封防止ケースＡ１によれば、蓋フラップ５，６に連続して繋がるとともに、少なくとも蓋フラップ５，６の表面に側縁５ｂ，６ｂ端に至る切り目が形成されてなる剥離部２０を蓋フラップ５，６の側縁５ｂ，６ｂに有し、剥離部２０上に接着テープ３０が貼着されるので、接着テープ３０を端部側から引き剥がすと、接着テープ３０が貼着した剥離部２０が剥がれる。ケースが開封された痕跡が、蓋フラップ５，６の外装表面が剥がれる形で残るので、第三者によりケースが不正に開封されたことがわかるようになる。 As described above, according to the unauthorized opening prevention case A1 according to the first embodiment, the lid flaps 5 and 6 are continuously connected to each other, and at least the surface of the lid flaps 5 and 6 has cuts reaching the ends of the side edges 5b and 6b. Since the formed peeling part 20 is provided on the side edges 5b and 6b of the lid flaps 5 and 6, and the adhesive tape 30 is stuck on the peeling part 20, when the adhesive tape 30 is peeled off from the end side, The peeling part 20 to which the adhesive tape 30 is attached is peeled off. Since the trace of the case being opened remains in a form in which the exterior surfaces of the lid flaps 5 and 6 are peeled off, it can be understood that the case has been opened illegally by a third party.

（第２実施形態）
第２実施形態に係る不正開封防止ケースＡ２では、第１実施形態に係る不正開封防止ケースに対して、蓋フラップ５，６及び底フラップ９，１０に設ける剥離部２０の個数が異なるが、四周側板部１，２，３，４、蓋フラップ５，６及び底フラップ９，１０などその他の構造は共通している。 (Second Embodiment)
The tamper-evident prevention case A2 according to the second embodiment differs from the tamper-evident prevention case according to the first embodiment in that the number of peeling portions 20 provided on the lid flaps 5 and 6 and the bottom flaps 9 and 10 is different. Other structures such as side plate portions 1, 2, 3, 4, lid flaps 5, 6 and bottom flaps 9, 10 are common.

従って、第２実施形態の実施形態の説明においては、第１実施形態と共通する部分には同符号を付して説明を省略する。また、以降の実施形態においても同様に、第１実施形態と共通する部分には同符号を付して説明を省略するものとする。 Therefore, in description of embodiment of 2nd Embodiment, the same code | symbol is attached | subjected to the part which is common in 1st Embodiment, and description is abbreviate | omitted. In the following embodiments as well, parts that are the same as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

図４（ａ）のシート基材Ｓ２の展開図で示すように、第２実施形態では、両蓋フラップ５，６の全ての側縁及び両底フラップ９，１０の全ての側縁に剥離部２０が設けられる構成が採用される。 As shown in the development view of the sheet base material S2 in FIG. 4A, in the second embodiment, peeling portions are formed on all side edges of the lid flaps 5 and 6 and all side edges of the bottom flaps 9 and 10. A configuration in which 20 is provided is employed.

同一フラップの左右側縁において接着テープ３０の引き剥がし方向が異なることに対応するため、第１実施形態と同様にして、第２実施形態の全ての剥離部２０の切り目２０ａ，２０ｂが接着テープ３０を引き剥がす方向に沿って形成され、各フラップ５，６，９，１０の側縁端に剥離部２０の一部である切離片２０１が設けられる。 In order to cope with the different peeling directions of the adhesive tape 30 at the left and right side edges of the same flap, the cuts 20a and 20b of all the peeling portions 20 of the second embodiment are bonded to the adhesive tape 30 in the same manner as in the first embodiment. Is formed along the direction of peeling off, and a separation piece 201 which is a part of the peeling portion 20 is provided at the side edge of each of the flaps 5, 6, 9, 10.

第２実施形態における底フラップ９，１０の剥離部２０の構成及び効果についても、蓋フラップ５，６の剥離部２０の構成及び効果と同様であるため説明を省略する。 Since the configuration and effect of the peeling portion 20 of the bottom flaps 9 and 10 in the second embodiment are the same as the configuration and effect of the peeling portion 20 of the lid flaps 5 and 6, description thereof will be omitted.

上述したように、第２実施形態に係る不正開封防止ケースＡ２であれば、蓋フラップ５，６の全ての側縁及び底フラップ９，１０の全ての側縁に剥離部２０が設けられるので、蓋フラップ５，６の何れの側縁から或いは底フラップ９，１０の何れの側縁から接着テープ３０が引き剥がされた場合であっても、ケースが不正に開封された痕跡がより残り易い。 As described above, in the case of the unauthorized opening prevention case A2 according to the second embodiment, since the peeling portions 20 are provided on all the side edges of the lid flaps 5 and 6 and all the side edges of the bottom flaps 9 and 10, Even when the adhesive tape 30 is peeled off from any side edge of the lid flaps 5, 6 or from any side edge of the bottom flaps 9, 10, a trace that the case is illegally opened is more likely to remain.

（第３実施形態）
第３実施形態に係る不正開封防止ケースＡ３では、第２実施形態に係る不正開封防止ケースＡ２に対して、両蓋フラップ５，６及び両底フラップ９，１０に設けた剥離部２１の形状が異なるのみでその他の構造は共通している。 (Third embodiment)
In the unauthorized opening prevention case A3 according to the third embodiment, the shape of the peeling portion 21 provided on the lid flaps 5 and 6 and the bottom flaps 9 and 10 is different from the unauthorized opening prevention case A2 according to the second embodiment. The only difference is the other structure.

図５の第３実施形態のシート基材Ｓ３の拡大図に示すように、第３実施形態における剥離部２１は、例えば、蓋フラップ６の側縁端に略山型形状の切り欠きを有する。 As shown in the enlarged view of the sheet substrate S3 of the third embodiment in FIG. 5, the peeling portion 21 in the third embodiment has, for example, a substantially mountain-shaped notch at the side edge of the lid flap 6.

略山型の切り欠きの形状は、一方の側縁端から蓋フラップ５，６の他方の側縁端に向かって凹状に切り欠いた２つの凹部２１２と、一方の側縁端よりも蓋フラップ５，６内側寄り、且つ凹部２１２よりも浅い切り欠きであり、凹部２１２間を側縁に平行となるように切り欠いた凸部２１３と、からなる形状である。 The shape of the substantially mountain-shaped notch is two concave portions 212 cut out in a concave shape from one side edge to the other side edge of the lid flaps 5 and 6, and the lid flap more than one side edge. 5 and 6, which are notches that are shallower than the recesses 212, and are formed with protrusions 213 that are notched so as to be parallel to the side edges between the recesses 212.

切り欠きの凹部２１２からは、蓋フラップ６から凹部２１２が切り離されるように、接着テープ３０を引き剥がす方向に沿って２本の切り目２１ａ，２１ｂがそれぞれ形成されている。 Two cuts 21a and 21b are formed along the direction in which the adhesive tape 30 is peeled off from the cutout recess 212 so that the recess 212 is separated from the lid flap 6.

凸部に切り目２１ａ，２１ｂが形成されることで、少なくとも切り目２１ａ，２１ｂの長さ分だけ凸部２１３が蓋フラップ５，６から切り離される切離片２１１が形成される。 By forming the cuts 21a and 21b in the convex part, a separation piece 211 is formed in which the convex part 213 is separated from the lid flaps 5 and 6 by at least the length of the cuts 21a and 21b.

このように、蓋フラップ５，６及び底フラップ９，１０の側縁よりも内側に切離片２１１が形成されていることで、接着テープ３０を引き剥がす際に、より剥離部２１が剥がされやすくなる。 As described above, since the separation piece 211 is formed inside the side edges of the lid flaps 5 and 6 and the bottom flaps 9 and 10, the peeling portion 21 is peeled off more when the adhesive tape 30 is peeled off. It becomes easy.

凹部２１２が形成されることによって、接着テープ３０が貼着された切り目２１ａと蓋フラップ５，６の閉じ合わせ縁間の部位、及び切り目２１ａと底フラップ９，１０の閉じ合わせ縁間の部位についても、接着テープ３０の引き剥がしに伴って剥がされやすくなるため、切離片２１１と合わせて開封された痕跡がより残りやすくなる。 By forming the recess 212, a portion between the cut edge 21a to which the adhesive tape 30 is adhered and the closing edge of the lid flaps 5 and 6 and a portion between the cut edge 21a and the closing edge of the bottom flaps 9 and 10 are provided. However, since the adhesive tape 30 is easily peeled off, the trace opened together with the separation piece 211 is more likely to remain.

これにより、接着テープ３０を引き剥がして不正開封防止ケースＡ３を開封する際に、接着テープ３０に付着した切離片２１１（剥離部２１）とともに蓋フラップ５，６或いは底フラップ９，１０の剥離部２１周辺の外装表面が剥がれる。 As a result, when the adhesive tape 30 is peeled off to open the tamper-evident prevention case A3, the lid flaps 5, 6 or the bottom flaps 9, 10 are peeled off together with the separation pieces 211 (peeling portions 21) attached to the adhesive tape 30. The exterior surface around the portion 21 is peeled off.

第３実施形態における底フラップ９，１０の剥離部２１の構成及び効果についても、蓋フラップ５，６の剥離部２１の構成及び効果と同様であるため説明を省略する。 Since the configuration and effect of the peeling portion 21 of the bottom flaps 9 and 10 in the third embodiment are the same as the configuration and effect of the peeling portion 21 of the lid flaps 5 and 6, description thereof will be omitted.

また、剥離部２５が形成される場合には、２つの切り目２５ａ，２５ｂが交差することで切り離された切離片２５１が形成され、不正開封防止ケースＡ６の開封時に接着テープ３０の引き剥がし方向と同一方向に切離片２５１が引き剥がされる。 Further, when the peeling portion 25 is formed, a separation piece 251 separated by the intersection of the two cuts 25a and 25b is formed, and the adhesive tape 30 is peeled off when the unauthorized opening prevention case A6 is opened. The separating piece 251 is peeled off in the same direction.

第５，６実施形態における蓋フラップ５及び底フラップ９，１０の剥離部２３，２４，２５の構成及び効果についても、蓋フラップ６の剥離部２３，２４，２５の構成及び効果と同様であるため説明を省略する。 The configurations and effects of the peeling portions 23, 24, and 25 of the lid flap 5 and the bottom flaps 9 and 10 in the fifth and sixth embodiments are the same as the configurations and effects of the peeling portions 23, 24, and 25 of the lid flap 6. Therefore, explanation is omitted.

上述した不正開封防止ケースＡ１〜Ａ６では、蓋フラップ５，６の側縁及び底フラップ９，１０の側縁に剥離部２０〜２５が形成され、何れのフラップ５，６，９，１０が開封された場合であっても開封された痕跡を残すことが出来ると説明したが、この構成に限定されるものではない。 In the unauthorized opening prevention cases A1 to A6 described above, peeling portions 20 to 25 are formed on the side edges of the lid flaps 5 and 6 and the bottom flaps 9 and 10, and any of the flaps 5, 6, 9 and 10 is opened. Although it has been explained that the opened trace can be left even in the case of being done, it is not limited to this configuration.

少なくとも蓋フラップ５，６の剥離部２０〜２５が、少なくとも一方の蓋フラップ５の側縁５ｂ及び他方の蓋フラップ６の前記側縁５ｂに対向する側縁６ｂに設けられるように構成されていれば、即ち、少なくとも蓋フラップ５，６にそれぞれ一つの剥離部２０〜２５が設けられた構成であれば、蓋フラップ５，６の左右何れから開封された場合であっても開封された痕跡を残すことが出来るのでよい。 At least the peeling portions 20 to 25 of the lid flaps 5 and 6 are configured to be provided at the side edge 5b of at least one lid flap 5 and the side edge 6b opposite to the side edge 5b of the other lid flap 6. In other words, at least the lid flaps 5 and 6 are provided with one peeling portion 20 to 25, respectively. Even if the lid flaps 5 and 6 are opened from either the left or right side, the opened traces are removed. You can leave it.

上述したように、剥離部２０〜２５は、第３実施形態のように切り欠きを設ける構成であってもよいが、切り欠きを設けない切り目だけで構成される構成が最も好ましい。剥離部が切り目だけで構成されることで、蓋フラップ５，６および底フラップ９，１０に連続して繋がった状態で、蓋フラップ５，６の側縁端および前記底フラップ９，１０の側縁端が切り離されて形成される構成であれば、製造する際に切り屑などのゴミが発生せず製造現場環境の向上に繋がる。 As described above, the peeling portions 20 to 25 may have a configuration in which a cutout is provided as in the third embodiment, but a configuration in which only the cut is provided with no cutout is most preferable. Since the peeling portion is formed only by the cut line, the side edge of the lid flaps 5 and 6 and the side of the bottom flaps 9 and 10 are connected to the lid flaps 5 and 6 and the bottom flaps 9 and 10 continuously. If it is the structure formed by cutting off the edge, dust such as chips is not generated during manufacturing, which leads to improvement of the manufacturing site environment.

上述では複数の剥離部２０〜２５の形状について示したが、封緘時に接着テープ３０に付着して剥がれやすいため、剥離部の形状は、切離片の各フラップ５，６，９，１０の側縁側の幅が広く設定されている形状が最も好ましい。 In the above description, the shapes of the plurality of peeling portions 20 to 25 have been shown. A shape having a wide edge side width is most preferable.

また、上述したように剥離部２０〜２５の中心位置が各フラップ５，６，９，１０の閉じ合わせ縁から接着テープ３０の半幅の位置に設定され、接着テープ３０が剥離部２０〜２５の一部に貼着されて不正開封防止ケースＡ１〜Ａ６が封緘されることが好適であるが、これに限定されるものではなく、剥離部２０〜２５全体が接着テープ３０で貼着されるように、各フラップ５，６，９，１０の閉じ合わせ縁寄りに剥離部２０〜２５を設けて不正開封防止ケースＡ１〜Ａ６が構成されるのであってもよい。 Further, as described above, the center position of the peeling portions 20 to 25 is set to the half width position of the adhesive tape 30 from the closing edge of each of the flaps 5, 6, 9, 10, and the adhesive tape 30 is It is preferable that the tamper-evident prevention cases A1 to A6 are sealed by being partly sealed, but the present invention is not limited to this, and the entire peeling portions 20 to 25 are stuck by the adhesive tape 30. In addition, the tampering prevention cases A1 to A6 may be configured by providing peeling portions 20 to 25 near the closing edges of the flaps 5, 6, 9, and 10, respectively.

更に、蓋フラップ５，６側縁或いは底フラップ９，１０の側縁に形成される剥離部２０〜２５の個数についても限定されるものではなく、例えば、蓋フラップ５，６及び底フラップ９，１０の各側縁における接着テープ３０が貼着される範囲内に、複数の剥離部２０〜２５が形成されるのであってもよい。 Further, the number of peeling portions 20 to 25 formed on the side edges of the lid flaps 5 and 6 or the side flaps 9 and 10 is not limited. For example, the lid flaps 5 and 6 and the bottom flaps 9 and 10 A plurality of peeling portions 20 to 25 may be formed within a range where the adhesive tape 30 at each side edge of 10 is attached.

上述した剥離部２０〜２５は、蓋フラップ５，６及び底フラップ９，１０の表面及び裏面ともに切り目が入れられて形成されるように説明したが、各フラップ５，６，９，１０の少なくとも表面側だけに切り目が形成されるものであってもよい。 The peeling portions 20 to 25 described above have been described so that both the front and back surfaces of the lid flaps 5 and 6 and the bottom flaps 9 and 10 are formed with cuts, but at least the flaps 5, 6, 9, and 10 are formed. A cut may be formed only on the surface side.

上述の説明中の数値については、いずれも設計事項であり、実施例に限定されるものではない。 All the numerical values in the above description are design items and are not limited to the embodiments.

以上説明した実施形態は、本発明の一例に過ぎず、本発明の作用効果を奏する範囲において具体的構成などを適宜変更設計できることは言うまでもない。 The embodiment described above is merely an example of the present invention, and it is needless to say that the specific configuration and the like can be appropriately changed and designed within the scope of the effects of the present invention.
