Description

この考案は、開封後の再封緘が可能な段ボール製の包装箱に関するものである。 The present invention relates to a corrugated cardboard packaging box that can be resealed after opening.

従来、下記特許文献１では、図７に示すように、主面壁５１及び側面壁５２を備え、側面壁５２の端辺から延びる内フラップ５３、５４と、主面壁５１の端辺から延びる外フラップ５５、５６とが重合部分で接着されて封緘されるラップアラウンド形式の段ボール製包装箱において、外フラップ５６の一側寄りに先端縁から基部の一端へかけて破断線５７が入れられ、内フラップ５３の先端に係止部５８が形成されたものが提案されている。 Conventionally, in Patent Document 1 below, as shown in FIG. 7, an inner flap 53, 54 having a main surface wall 51 and a side wall 52 and extending from the end side of the side wall 52 and an outer flap extending from the end side of the main surface wall 51 In a wraparound type corrugated cardboard packaging box in which 55 and 56 are bonded and sealed at the overlapped portion, a breaking line 57 is inserted from the tip edge to one end of the base on one side of the outer flap 56, and the inner flap is inserted. It has been proposed that the locking portion 58 is formed at the tip of the 53.

この包装箱は、開封に際して、外フラップ５６を破断線５７に沿って破断し、外フラップ５５、５６及び内フラップ５３、５４を開く。 Upon opening, the packaging box breaks the outer flap 56 along the break line 57 and opens the outer flaps 55, 56 and the inner flaps 53, 54.

特開２００９－１０２０５６号公報Japanese Unexamined Patent Publication No. 2009-102056

しかしながら、上記のような包装箱は、内フラップ５３と外フラップ５６の１点での係合のみにより再封緘状態が保持されるため、持ち上げた時などに僅かに変形すると、係合が外れて開封状態になってしまうという問題がある。 However, since the resealed state of the packaging box as described above is maintained only by the engagement of the inner flap 53 and the outer flap 56 at one point, the engagement is disengaged when the packaging box is slightly deformed when it is lifted. There is a problem that it will be in an opened state.

そこで、この考案は、簡単に安定した再封緘状態とすることができる段ボール製の包装箱を提供しようとするものである。 Therefore, the present invention is intended to provide a corrugated cardboard packaging box that can be easily and stably resealed.

上記課題を解決するため、この考案は、主面壁及び側面壁がそれぞれ対向し、前記側面壁の端辺から延びる内フラップと、前記主面壁の端辺から延びる外フラップとが接着されて封緘され、破断による開封後の再封緘機能を備えた段ボール製の包装箱において、
天面となる前記主面壁及びこれに連なる外フラップには、前記外フラップの先端側から前記主面壁へ延びる第１破断線が入れられ、
前記対向する側面壁のうち、一方の側面壁と前記主面壁との境界をなす折目線が開封時及び再封緘時のヒンジ線とされ、
前記外フラップには、前記一方の側面壁に連なる内フラップとの接着部を避けて、前記内フラップに重なる部分を通る第２破断線が入れられ、
前記内フラップには、天面側となる角部寄りに押圧片を形成するための斜め方向に延びる谷折線が入れられ、
開封に際しては、前記主面壁の第１破断線とヒンジ線との間の部分を天面蓋部とし、前記外フラップの第１破断線と第２破断線との間の部分を側面蓋部として、前記外フラップ及び主面壁を第１破断線と第２破断線とに沿って破断することにより、前記天面蓋部と側面蓋部とを共に開き、
再封緘に際しては、前記内フラップの押圧片を前記谷折線を軸として外側へ折り曲げ、前記天面蓋部及び側面蓋部を閉じると、前記側面蓋部の第２破断線に臨む部分が前記押圧片で押さえられ、前記側面蓋部の第１破断線に臨む端縁が前記外フラップの残存部の第１破断線に臨む端縁に当接して摩擦を生じ、前記天面蓋部及び側面蓋部が閉じた状態に保持されるものとしたのである。 In order to solve the above problems, in this invention, the main face wall and the side wall face each other, and the inner flap extending from the end edge of the side wall and the outer flap extending from the end edge of the main face wall are adhered and sealed. In a corrugated cardboard packaging box with a resealing function after opening due to breakage,
A first breaking line extending from the tip end side of the outer flap to the main surface wall is inserted in the main surface wall serving as the top surface and the outer flap connected to the main surface wall.
Of the facing side walls, the crease line forming the boundary between one side wall and the main face wall is used as a hinge line at the time of opening and resealing.
The outer flap is provided with a second breaking line that passes through a portion that overlaps the inner flap, avoiding an adhesive portion with the inner flap that is connected to the one side wall.
The inner flap is provided with a valley fold line extending in an oblique direction for forming a pressing piece near the corner on the top surface side.
When opening, the portion between the first break line and the hinge line of the main surface wall is used as the top cover portion, and the portion between the first break line and the second break line of the outer flap is used as the side lid portion. By breaking the outer flap and the main surface wall along the first break line and the second break line, the top cover portion and the side cover portion are opened together.
At the time of resealing, when the pressing piece of the inner flap is bent outward around the valley fold line and the top cover portion and the side surface lid portion are closed, the portion of the side surface lid portion facing the second breaking line is pressed. It is pressed by one piece, and the edge facing the first breaking line of the side lid abuts on the edge facing the first breaking line of the remaining part of the outer flap to cause friction, and the top lid and the side lid The part was supposed to be held in a closed state.

また、前記外フラップの第１破断線は、前記外フラップの残存部と内フラップとの接着部よりも、前記第２破断線に寄って位置しているものとし、再封緘に際して、内フラップに強固に固定された外フラップの残存部により、側面蓋部がしっかりと閉じた状態に保持されるようにしたのである。 Further, it is assumed that the first break line of the outer flap is located closer to the second break line than the adhesive portion between the remaining portion of the outer flap and the inner flap, and is attached to the inner flap at the time of resealing. The remnants of the tightly fixed outer flap ensured that the side lids were held in a tightly closed position.

また、前記第２破断線は、前記外フラップと主面壁との境界をなす折目線を越えて、前記主面壁を通り前記ヒンジ線へ至るものとし、第２破断線が重なる内フラップと外フラップとの接着面積を確保すると共に、開封時に第２破断線に沿って外フラップと主面壁とをスムーズに破断できるようにしたのである。 Further, the second breaking line extends beyond the crease line forming the boundary between the outer flap and the main surface wall, passes through the main surface wall, and reaches the hinge line, and the inner flap and the outer flap on which the second breaking line overlaps. In addition to ensuring the adhesion area with the above, the outer flap and the main surface wall can be smoothly broken along the second breaking line at the time of opening.

さらに、前記外フラップの第１破断線が延びる方向は、材料となる段ボールの中しんの段頂が延びる方向である段目方向に交差しているものとし、再封緘時に、側面蓋部の第１破断線に臨む端縁と外フラップの残存部の第１破断線に臨む端縁との間に大きな摩擦力が生じるようにしたのである。 Further, it is assumed that the direction in which the first break line of the outer flap extends intersects the step direction in which the step top of the corrugated cardboard used as the material extends, and the side lid portion is the first at the time of resealing. A large frictional force is generated between the edge facing the first breaking line and the edge facing the first breaking line of the remaining part of the outer flap.

この考案に係る包装箱では、押圧片を外側へ折り曲げて再封緘すると、側面蓋部の第２破断線に臨む部分が押圧片で押さえられて外側へ開かなくなり、側面蓋部の第１破断線に臨む端縁と外フラップの残存部の第１破断線に臨む端縁との間に摩擦が生じて、側面蓋部が２点留めされ、天面蓋部及び側面蓋部が閉じた状態に保持される。 In the packaging box according to the present invention, when the pressing piece is bent outward and resealed, the portion of the side lid portion facing the second breaking line is pressed by the pressing piece and cannot be opened outward, and the first breaking line of the side lid portion is prevented. Friction occurs between the edge facing the surface and the edge facing the first break line of the remaining part of the outer flap, the side lid is fastened at two points, and the top lid and the side lid are closed. Be retained.

このため、一方の主面壁を天面とした状態での高さが低く、外フラップが短いラップアラウンド形式のものであっても、外フラップの強い反発力に抗して、簡単に安定した再封緘状態とすることができる。 For this reason, even if the height is low with one main wall as the top surface and the outer flap is a short wraparound type, it can be easily and stably regenerated against the strong repulsive force of the outer flap. It can be in a sealed state.

The step direction, which is the direction in which the step top of the corrugated cardboard extends, is directed in the direction orthogonal to the crease lines f 1 , f 2 , f 3 , and f 4 .

側面壁２，４の両側の端辺には、それぞれ内フラップ５，６が折目線ｆ５，ｆ６を介して連設され、主面壁１，３の両側の端辺には、それぞれ外フラップ７，８が折目線ｆ７，ｆ８を介して連設されている。 Inner flaps 5 and 6 are connected to both ends of the side walls 2 and 4 via the crease lines f 5 and f 6 , respectively, and outer flaps are connected to both ends of the main surface walls 1 and 3, respectively. 7 and 8 are connected through the crease lines f7 and f8.

折目線ｆ１～ｆ８は、段ボールを表面側が凸となる山折りにする軸となるため、それぞれ段ボールを裏面から押圧した押罫とされている。 The crease lines f 1 to f 8 are shafts for folding the corrugated cardboard into mountain folds whose front surface side is convex, so that the corrugated cardboard is pressed from the back surface.

外フラップ７，８の裏面には、内フラップ５，６との接着用のホットメルト接着剤がそれぞれ塗布されて接着部１０となる部分に、段ボールを厚さ方向の途中まで切り込んだミシン目状の切目線がＸ字状に入れられている。この切目線は、ホットメルト接着剤の定着性を向上させるためのものである。 Hot melt adhesives for adhesion to the inner flaps 5 and 6 are applied to the back surfaces of the outer flaps 7 and 8, respectively, and the corrugated cardboard is cut halfway in the thickness direction at the portion to be the adhesive portion 10. The cut line of is put in an X shape. This cut line is for improving the fixability of the hot melt adhesive.

主面壁１及びこれに連なる外フラップ７には、封緘時に内フラップ６が重なる接着部１０から幅方向の中央側へ離れて、外フラップ７の先端側から主面壁１へ延びる第１破断線１１が入れられている。 On the main surface wall 1 and the outer flap 7 connected to the main surface wall 1, the first breaking line 11 extending from the tip end side of the outer flap 7 to the main surface wall 1 away from the adhesive portion 10 on which the inner flap 6 overlaps at the time of sealing toward the center side in the width direction. Is put in.

外フラップ７の第１破断線１１は、段ボールを厚さ方向に貫通した直線の切目がミシン目状に断続するものとされている。主面壁１の第１破断線１１は、段ボールを厚さ方向に貫通した鉤状の切目が断続する片ジッパーとされている。 The first break line 11 of the outer flap 7 is such that straight cuts penetrating the corrugated cardboard in the thickness direction are interrupted in a perforated manner. The first break line 11 of the main surface wall 1 is a single zipper having hook-shaped cuts penetrating the corrugated cardboard in the thickness direction.

また、外フラップ７には、内フラップ５との接着部１０を避けて、内フラップ５に重なる部分を通るように、主面壁１との境界をなす折目線ｆ７に対して斜め方向に延びる第２破断線１２が入れられている。第２破断線１２は、折目線ｆ７を越えて主面壁１を通り、折目線ｆ１に交わるように延びている。 Further, the outer flap 7 extends diagonally with respect to the crease line f7 forming the boundary with the main surface wall 1 so as to pass through the portion overlapping the inner flap 5 while avoiding the adhesive portion 10 with the inner flap 5. The second break line 12 is inserted. The second break line 12 extends beyond the crease line f7, passes through the main surface wall 1 , and intersects the crease line f1.

第２破断線１２は、外フラップ７及び主面壁１の内部において、段ボールを厚さ方向に貫通した鉤状の切目が断続する片ジッパーとされている。 The second break line 12 is a single zipper inside the outer flap 7 and the main surface wall 1 in which hook-shaped cuts penetrating the corrugated cardboard in the thickness direction are intermittent.

内フラップ５には、天面側となる角部寄りに押圧片１３を形成するため、外フラップ７の第２破断線１２に対応して斜め方向に延びる谷折線１４が入れられている。谷折線１４は、段ボールを表面側が凹となる方向に折り曲げる軸になるものであり、段ボールを厚さ方向に押圧した押罫又は切目と折目とが交互に断続するリード罫とされている。 The inner flap 5 has a valley fold line 14 extending in an oblique direction corresponding to the second break line 12 of the outer flap 7 in order to form the pressing piece 13 near the corner portion on the top surface side. The valley fold line 14 serves as an axis for bending the corrugated cardboard in a direction in which the surface side is concave, and is a ruled line for pressing the corrugated cardboard in the thickness direction or a lead ruled line in which cuts and creases are alternately interrupted.

外フラップ８には、先端縁の中央部に臨む部分に、２本の切目線とその端部間を結ぶ折目線で区画された開封用の押込部１５が設けられている。 The outer flap 8 is provided with a push-in portion 15 for opening, which is divided by a crease line connecting two cut lines and the end portions in a portion facing the central portion of the tip edge.

また、このブランクでは、折目線ｆ１における両側の第２破断線１２との交点の間の部分は、開封及び再封緘時のヒンジ線ｈになるものとされている。主面壁１の第１破断線１１とヒンジ線ｈとの間の部分は天面蓋部１ａとされ、その他の部分は残存部１ｂとされている。外フラップ７の第１破断線１１と第２破断線１２の間の部分は側面蓋部７ａとされて、その他の部分は残存部７ｂとされている。 Further, in this blank, the portion of the crease line f1 between the intersections with the second break lines 12 on both sides is assumed to be the hinge line h at the time of opening and resealing. The portion of the main surface wall 1 between the first break line 11 and the hinge line h is the top cover portion 1a, and the other portion is the remaining portion 1b. The portion of the outer flap 7 between the first break line 11 and the second break line 12 is a side lid portion 7a, and the other portion is a remaining portion 7b.

（組立及び封緘）
上記のようなブランクを図１に示す立体形状に組み立てて封緘するには、底面となる主面壁３から折目線ｆ２，ｆ３に沿って側面壁２，４を起立させ、折目線ｆ４，ｆ１に沿って継代片９及び天面となる主面壁１を折り重ねて貼り合わせる。 (Assembly and seal)
In order to assemble the above blank into the three-dimensional shape shown in FIG. 1 and seal it, the side walls 2 and 4 are erected from the main surface wall 3 which is the bottom surface along the crease lines f2 and f3, and the crease line f4. , The joint piece 9 and the main surface wall 1 to be the top surface are folded and pasted together along f1.

次に、折目線ｆ５，ｆ６に沿って内フラップ５，６を内側へ折り曲げ、折目線ｆ７，ｆ８に沿って外フラップ７，８をそれぞれ下方及び上方へ折り曲げて、内フラップ５，６と外フラップ７，８とをそれぞれ接着部１０で貼り合わせる。 Next, the inner flaps 5 and 6 are bent inward along the crease lines f5 and f6, and the outer flaps 7 and 8 are bent downward and upward along the crease lines f7 and f8, respectively, and the inner flap 5 is bent. , 6 and the outer flaps 7 and 8 are bonded together at the adhesive portion 10.

このとき、第２破断線１２は、外フラップ７と主面壁１との境界をなす折目線ｆ７を越えて、主面壁１を通りヒンジ線ｈへ至るものとされているので、内フラップ５と外フラップ７との接着部１０の面積が確保され、内フラップ５と外フラップ７とをしっかりと貼り合わせることができる。 At this time, the second break line 12 crosses the crease line f7 forming the boundary between the outer flap 7 and the main surface wall 1, passes through the main surface wall 1, and reaches the hinge line h. Therefore, the inner flap 5 The area of the adhesive portion 10 between the outer flap 7 and the outer flap 7 is secured, and the inner flap 5 and the outer flap 7 can be firmly bonded to each other.

（開封）
このように封緘した包装箱を開封するには、図２に示すように、両側の外フラップ８の押込部１５を押し込んで、側面蓋部７ａを外側へ引っ張り、外フラップ７を第１破断線１１及び第２破断線１２に沿って破断する。 (Opened)
In order to open the package box sealed in this way, as shown in FIG. 2, the pushing portions 15 of the outer flaps 8 on both sides are pushed in, the side lid portions 7a are pulled outward, and the outer flaps 7 are the first breaking line. It breaks along the 11 and the second break line 12.

次に、両側の側面蓋部７ａを掴んだ状態で、天面蓋部１ａをヒンジ線ｈを軸として引き起こし、これに伴い、主面壁１を第１破断線１１及び第２破断線１２に沿って破断し、天面蓋部１ａと両側の側面蓋部７ａとを開く。 Next, with the side lids 7a on both sides gripped, the top cover 1a is raised with the hinge line h as the axis, and the main surface wall 1 is brought along the first break line 11 and the second break line 12. The top surface lid portion 1a and the side surface lid portions 7a on both sides are opened.

このとき、第２破断線１２は、外フラップ７から主面壁１へかけて直線的に斜めに連続しているので、外フラップ７と主面壁１とを途切れることなくスムーズに破断できる。この開封後において、主面壁１の残存部１ｂと両側の外フラップ７の残存部７ｂとは、閉止状態で固定されたままとなる。 At this time, since the second breaking line 12 is linearly and diagonally continuous from the outer flap 7 to the main surface wall 1, the outer flap 7 and the main surface wall 1 can be smoothly broken without interruption. After this opening, the remaining portion 1b of the main surface wall 1 and the remaining portion 7b of the outer flaps 7 on both sides remain fixed in the closed state.

（再封緘）
このように開封した包装箱を再封緘するには、図３に示すように、両側の内フラップ５の押圧片１３を谷折線１４を軸として外側へ折り曲げ、その後、天面蓋部１ａ及び両側の側面蓋部７ａを閉じる。 (Reseal)
In order to reseal the package box opened in this way, as shown in FIG. 3, the pressing pieces 13 of the inner flaps 5 on both sides are bent outward around the valley fold line 14, and then the top cover portion 1a and both sides are bent. The side lid portion 7a of the is closed.

これにより、側面蓋部７ａの第２破断線１２に臨む部分が押圧片１３で押さえられると共に、側面蓋部７ａの第１破断線１１に臨む端縁が外フラップ７の残存部７ｂの第１破断線１１に臨む端縁に当接して摩擦を生じ、天面蓋部１ａ及び両側の側面蓋部７ａが閉じた状態に保持される。 As a result, the portion of the side surface lid portion 7a facing the second break line 12 is pressed by the pressing piece 13, and the end edge of the side surface lid portion 7a facing the first break line 11 is the first of the remaining portion 7b of the outer flap 7. Friction is generated by abutting on the edge facing the break line 11, and the top surface lid portion 1a and the side surface lid portions 7a on both sides are held in a closed state.

この再封緘状態では、外フラップ７の第１破断線１１が外フラップ７の残存部７ｂと内フラップ６との接着部１０よりも、第２破断線１２に寄って位置しているので、内フラップ６に強固に固定された外フラップ７の残存部７ｂにより、側面蓋部７ａがしっかりと閉じた状態に保持される。 In this resealed state, the first break line 11 of the outer flap 7 is located closer to the second break line 12 than the adhesive portion 10 between the remaining portion 7b of the outer flap 7 and the inner flap 6. The side lid portion 7a is held in a tightly closed state by the remaining portion 7b of the outer flap 7 firmly fixed to the flap 6.

また、段ボールの段目方向に対して、外フラップ７の第１破断線１１が延びる方向が交差しているので、側面蓋部７ａの第１破断線１１に臨む端縁と外フラップ７の残存部７ｂの第１破断線１１に臨む端縁との間に大きな摩擦力が生じ、これによっても、側面蓋部７ａがしっかりと閉じた状態に保持され、再封緘状態が安定する。 Further, since the direction in which the first breaking line 11 of the outer flap 7 extends intersects with the step direction of the corrugated cardboard, the end edge of the side lid portion 7a facing the first breaking line 11 and the remaining outer flap 7. A large frictional force is generated between the portion 7b and the edge facing the first break line 11, which also keeps the side lid portion 7a in a tightly closed state and stabilizes the resealed state.

（効果）
上記のような包装箱では、押圧片１３を外側へ折り曲げて再封緘すると、側面蓋部７ａの第２破断線１２に臨む部分が押圧片１３で押さえられて、外側へ開かなくなり、側面蓋部７ａの第１破断線１１に臨む端縁と外フラップ７の残存部７ｂの第１破断線１１に臨む端縁との間に摩擦が生じて、側面蓋部７ａが２点留めされ、天面蓋部１ａ及び両側の側面蓋部７ａが閉じた状態に保持される。 (effect)
In a packaging box as described above, when the pressing piece 13 is bent outward and resealed, the portion of the side lid portion 7a facing the second breaking line 12 is pressed by the pressing piece 13 and cannot be opened outward, and the side lid portion Friction occurs between the edge of 7a facing the first break line 11 and the edge of the remaining portion 7b of the outer flap 7 facing the first break line 11, and the side lid portion 7a is fastened at two points to the top surface. The lid portion 1a and the side lid portions 7a on both sides are held in a closed state.

このため、主面壁１を天面とした状態での高さが低く、外フラップ７が短いラップアラウンド形式のものであっても、外フラップ７の強い反発力に抗して、簡単に安定した再封緘状態とすることができる。 Therefore, even if the height is low when the main surface wall 1 is the top surface and the outer flap 7 is a short wraparound type, it is easily stabilized against the strong repulsive force of the outer flap 7. It can be resealed.

（その他）
なお、上記実施形態では、外フラップ７の第１破断線１１が垂直に延びるものを例示したが、図５に示すように、外フラップ７の第１破断線１１は、側面蓋部７ａの下方部分が残存部７ｂに食い込む方向へ傾斜したものとしてもよい。 (others)
In the above embodiment, the first break line 11 of the outer flap 7 extends vertically, but as shown in FIG. 5, the first break line 11 of the outer flap 7 is below the side lid portion 7a. The portion may be inclined in the direction of biting into the remaining portion 7b.

また、主面壁１及び外フラップ７の第１破断線１１は、真っすぐな直線とする必要はなく、途中で屈曲したものや曲線としてもよい。 Further, the first break line 11 of the main surface wall 1 and the outer flap 7 does not have to be a straight straight line, but may be bent or curved in the middle.

また、第２破断線１２が外フラップ７から主面壁１を通りヒンジ線ｈへ至る直線状のものを例示したが、第２破断線１２は、接着部１０及び押圧片１３が確保されるように、湾曲又は屈曲して外フラップ７の角部へ向かい、主面壁１を通らないものとしてもよい。 Further, although the linear one in which the second break line 12 passes from the outer flap 7 to the hinge line h through the main surface wall 1 is exemplified, the second break line 12 is such that the adhesive portion 10 and the pressing piece 13 are secured. It may be curved or bent toward the corner of the outer flap 7 and not pass through the main surface wall 1.

また、内フラップ５の谷折線１４が外フラップ７の第２破断線１２とほぼ重なるものを例示したが、図６に示すように、内フラップ５が大きい場合、谷折線１４は、第２破断線１２よりも第１破断線１１寄りに離れた部分に位置するようにしてもよい。 Further, an example is shown in which the valley fold line 14 of the inner flap 5 substantially overlaps with the second break line 12 of the outer flap 7. However, as shown in FIG. 6, when the inner flap 5 is large, the valley fold line 14 has a second break. It may be located at a portion closer to the first break line 11 than the line 12.

また、上記のような再封緘構造を包装箱の両側に設けたものを例示したが、この再封緘構造は、包装箱の片側のみに設けても、再封緘機能を得ることができる。 Further, although the above-mentioned resealing structure provided on both sides of the packaging box is exemplified, this resealing structure can obtain the resealing function even if it is provided on only one side of the packaging box.
