Description

本発明は、包装箱に関するものであり、特に、内箱と外箱からなる包装箱に関するものである。 The present invention relates to a packaging box, and more particularly to a packaging box including an inner box and an outer box.

従来より、内箱と外箱からなる包装箱として、特許文献１に示す２ピース包装箱が存在する。 Conventionally, as a packaging box composed of an inner box and an outer box, there is a two-piece packaging box shown in Patent Document 1.

特許文献１の２ピース包装箱は、トレイ１とカバー２とから成り、トレイ１の側壁の延長部として突起１３が設けられ、カバー２の側壁２１と端壁２２がなす稜部に端壁２２に及んで開口する抜窓部２６が設けられ、
梱包作業時にカバー２をトレイ１に被せると、突起１３が抜窓部２６に係合して、トレイ１とカバー２とが固定され、カバー２の側壁２１に入れた切目線２５を切断し、カバー２の端壁２２を天壁２０との境界を軸として下部の間隔が広がるように揺動させると、カバー２が解体されるとともに、突起１３が抜窓部２６から引き抜かれて、トレイ１とカバー２が分離するものである。 The two-piece packaging box of Patent Document 1 is composed of a tray 1 and a cover 2, and a protrusion 13 is provided as an extension of the side wall of the tray 1, and the end wall 22 is formed at a ridge formed by the side wall 21 and the end wall 22 of the cover 2. A window 26 is provided to open the window 26.
When the cover 2 is put on the tray 1 during the packing work, the protrusion 13 engages with the window opening portion 26, the tray 1 and the cover 2 are fixed, and the cut line 25 inserted in the side wall 21 of the cover 2 is cut. When the end wall 22 of the cover 2 is swung around the boundary with the top wall 20 so that the space between the lower parts is widened, the cover 2 is disassembled and the protrusion 13 is pulled out from the window portion 26 to form the tray 1. And the cover 2 are separated.

特許第５７１９０９４号公報Japanese Patent No. 5719094

しかし、特許文献１の２ピース包装箱においては、商品の梱包に際して、内箱としてのトレイ１を組み立てた状態で外箱としてのカバー２を被せるので、包装箱の組立てが容易でないという問題があった。つまり、手作業で組み立てる場合はもちろん、自動製函機を用いる場合であっても、トレイ１を組み立てた状態でカバー２を被せる機能を要するため、包装箱の組立てが容易でない。 However, in the two-piece packaging box of Patent Document 1, when the product is packed, the tray 1 as the inner box is covered with the cover 2 as the outer box, so that there is a problem that the packaging box is not easy to assemble. rice field. That is, it is not easy to assemble the packaging box because the function of covering the cover 2 in the assembled state of the tray 1 is required not only when assembling by hand but also when using an automatic box making machine.

また、トレイ１の延長部としての突起１３が抜窓部２６に係合し、突起１３は１枚の片部により構成されているので、突起１３の強度が十分でなく、突起１３が折れ曲がるおそれがあり、特に、突起１３が包装箱の外側に折れ曲がった場合に、突起１３が抜窓部２６から脱落するおそれがある。特に、特許文献１の２ピース包装箱においては、トレイ１とカバー２とが接着されていないので、収納する商品が重い場合には、包装箱の輸送中に包装箱が揺れることにより、突起１３が折れ曲がるおそれがあるとともに、トレイ１がカバー２の中で揺れて、突起１３が抜窓部２６から抜けるおそれがある。さらに、トレイ１の高さが低い場合には、トレイ１の側面とカバー２の側面の接触面積が小さいので、トレイ１が変形しやすく（特に、商品が重いとより変形しやすい）、トレイ１が変形すると、その分突起１３が折れ曲がりやすくなる。また、トレイ１を組み立てた状態でカバー２を被せるので、トレイ１とカバー２とが接着された構成とするのが困難である。 Further, since the protrusion 13 as an extension portion of the tray 1 engages with the window opening portion 26 and the protrusion 13 is composed of one single portion, the strength of the protrusion 13 is not sufficient and the protrusion 13 may be bent. In particular, when the protrusion 13 is bent to the outside of the packaging box, the protrusion 13 may fall off from the window opening portion 26. In particular, in the two-piece packaging box of Patent Document 1, since the tray 1 and the cover 2 are not adhered to each other, when the product to be stored is heavy, the packaging box shakes during the transportation of the packaging box, and the protrusion 13 May bend, and the tray 1 may sway in the cover 2 and the protrusion 13 may come out of the window opening portion 26. Further, when the height of the tray 1 is low, the contact area between the side surface of the tray 1 and the side surface of the cover 2 is small, so that the tray 1 is easily deformed (particularly, it is more easily deformed when the product is heavy), and the tray 1 is easily deformed. When is deformed, the protrusion 13 is easily bent by that amount. Further, since the cover 2 is covered with the tray 1 assembled, it is difficult to make the tray 1 and the cover 2 adhere to each other.

そこで、本発明は、内箱と外箱を有する包装箱において、包装箱の組立てに際して内箱と外箱の係合が容易であり、また、内箱を外箱に係合させる部材の強度を十分得ることができ、収納される商品が重い場合や、内箱の高さが低い場合でも、内箱が外箱から脱落するのを防止することができる包装箱を提供することを目的とする。 Therefore, in the present invention, in a packaging box having an inner box and an outer box, it is easy to engage the inner box and the outer box when assembling the packaging box, and the strength of the member for engaging the inner box with the outer box is increased. It is an object of the present invention to provide a packaging box that can be sufficiently obtained and can prevent the inner box from falling off from the outer box even when the stored product is heavy or the inner box is low in height. ..

第１の構成の包装箱によれば、包装箱を立体状に組み立てる際に、内側スリーブ状部と外側スリーブ状部を筒状に広げるのみで、第１連結部が第１開口部に入り込んで係合し、第２連結部が第２開口部に入り込んで係合するので、包装箱の組立てに際して内箱部と外箱部の係合が容易である。 According to the packaging box having the first configuration, when the packaging box is assembled in a three-dimensional shape, the inner sleeve-shaped portion and the outer sleeve-shaped portion are simply expanded into a cylindrical shape, and the first connecting portion enters the first opening. Since the second connecting portion is engaged and the second connecting portion enters and engages with the second opening, the inner box portion and the outer box portion can be easily engaged when assembling the packaging box.

また、第１連結部が第１開口部に入り込み、第２連結部が第２開口部に入り込んだ状態となるので、内箱部を外箱部に係合させる部材である第１連結部や第２連結部が折れ曲がるおそれがなく、第１連結部と第２連結部の強度を十分得ることができる。 Further, since the first connecting portion enters the first opening and the second connecting portion enters the second opening, the first connecting portion which is a member for engaging the inner box portion with the outer box portion and the like. There is no possibility that the second connecting portion will be bent, and sufficient strength can be obtained between the first connecting portion and the second connecting portion.

さらに、第１連結部が第１開口部に入り込んだ状態であるとともに、第２連結部が第２開口部に入り込んだ状態であり、さらに、第１分離部と第１中間構成部が接着されているとともに、第２分離部と第２中間構成部が接着されているので、収納される商品が重い場合や、内箱の高さが低い場合でも、内箱が外箱から脱落するのを防止することができる。 Further, the first connecting portion is in a state of being inserted into the first opening, the second connecting portion is in a state of being inserted into the second opening, and the first separating portion and the first intermediate component are bonded to each other. At the same time, since the second separation part and the second intermediate component part are adhered, even if the stored product is heavy or the height of the inner box is low, the inner box can be prevented from falling off from the outer box. Can be prevented.

なお、上記第１の構成において、第１連結部が第１開口部に入り込んだ状態において、第１連結部と第１開口部の横断面を仮想的に平面視した場合には、第１連結部が第１開口部の底面の厚み領域と重なり、第２連結部が第２開口部に入り込んだ状態において、第２連結部と第２開口部の横断面を仮想的に平面視した場合には、第２連結部が第２開口部の底面の厚み領域と重なることを特徴とするものとしてもよい。 In the first configuration, when the cross section of the first connecting portion and the first opening is virtually viewed in a plan view in a state where the first connecting portion is inserted into the first opening, the first connection is made. When the cross section of the second connecting portion and the second opening is virtually viewed in a plan view in a state where the portion overlaps with the thickness region of the bottom surface of the first opening and the second connecting portion enters the second opening. May be characterized in that the second connecting portion overlaps with the thickness region of the bottom surface of the second opening.

また、第２には、上記第１の構成において、内側スリーブ状部と外側スリーブ状部を筒状に組み立てた状態では、第１対象外側側面部と対象隣接外側側面部とがなす角部における第１開口部が形成された領域以外の領域の外周面は略円弧状に形成されるとともに、第２対象外側側面部と対象隣接外側側面部とがなす角部における第２開口部が形成された領域以外の領域の外周面は略円弧状に形成され、第１連結部が、第１対象外側側面部の外側の面の仮想延長面（１１０Ｒ）と対象隣接外側側面部の外側の面の仮想延長面（１２０Ｒ）がなす仮想角部（Ｒ１）から外側に突出することなく、第１開口部に入り込んだ状態であるとともに、第２連結部が、第２対象外側側面部の外側の面の仮想延長面（１４０Ｒ）と対象隣接外側側面部の外側の面の仮想延長面（１２０Ｒ）がなす仮想角部（Ｒ２）から外側に突出することなく、第２開口部に入り込んだ状態であることを特徴とする。 Secondly, in the first configuration, in the state where the inner sleeve-shaped portion and the outer sleeve-shaped portion are assembled into a cylindrical shape, the corner portion formed by the first target outer side surface portion and the target adjacent outer side surface portion is formed. The outer peripheral surface of the region other than the region where the first opening is formed is formed in a substantially arc shape, and the second opening is formed at the corner formed by the second target outer side surface portion and the target adjacent outer side surface portion. The outer peripheral surface of the region other than the above region is formed in a substantially arc shape, and the first connecting portion is a virtual extension surface (110R) of the outer surface of the first target outer side surface portion and the outer surface of the target adjacent outer side surface portion. It is in a state of entering the first opening without protruding outward from the virtual angle portion (R1) formed by the virtual extension surface (120R), and the second connecting portion is the outer surface of the second target outer side surface portion. It is in a state of entering the second opening without protruding outward from the virtual angle portion (R2) formed by the virtual extension surface (140R) of the above and the virtual extension surface (120R) of the outer surface of the outer side surface adjacent to the target.

次に、内箱部Ａと外箱部Ｂは、分離部１４、４４の箇所で互いに接着されている。つまり、分離部１４の外側の面と中正面部１１４の内側の面とが接着剤その他の接着手段により接着されるとともに、分離部４４の外側の面と中背面部１４４の内側の面とが接着剤その他の接着手段により接着されることにより、包装箱Ｐが全体に一体に形成される。具体的には、図１４に示す分離部１４のハッチングに示す領域と図１７に示す中正面部１１４のハッチングに示す領域とが接着されて（つまり、分離部１４のハッチングに示す領域と中正面部１１４のハッチングに示す領域との間に接着剤層が設けられている）、同様に、図１４に示す分離部４４のハッチングに示す領域と図１７に示す中背面部１４４のハッチングに示す領域とが接着されている（つまり、分離部４４のハッチングに示す領域と中背面部１４４のハッチングに示す領域との間に接着剤層が設けられている）。これにより、外箱部Ｂのスリーブ状部１０５は、内箱部Ａにおけるスリーブ状部５の外側の面に沿って設けられ、例えば、正面部１０の外側の面に沿って正面部１１０が設けられ、側面部２０の外側の面に沿って側面部１２０が設けられ、側面部３０の外側の面に沿って側面部１３０が設けられ、背面部４０の外側の面に沿って背面部１４０が設けられている。該接着剤の接着力は、中正面部１１４を正面側斜め上方に引き上げることにより、切目線１１６Ｋａ、１１６Ｋｂが破断するとともに切目線１６Ｋａ、１６Ｋｂも破断して、分離部１４が正面部１０から分離し、中正面部１１４に接着した状態で中正面部１１４に従動するように設定されている。同様に、該接着剤の接着力は、中背面部１４４を背面側斜め上方に引き上げることにより、切目線１４６Ｋａ、１４６Ｋｂが破断するとともに切目線４６Ｋａ、４６Ｋｂも破断して、分離部４４が背面部４０から分離し、中背面部１４４に接着した状態で中背面部１４４に従動するように設定されている。 Next, the inner box portion A and the outer box portion B are adhered to each other at the separation portions 14 and 44. That is, the outer surface of the separation portion 14 and the inner surface of the middle front portion 114 are adhered by an adhesive or other adhesive means, and the outer surface of the separation portion 44 and the inner surface of the middle back portion 144 are bonded to each other. The packaging box P is integrally formed as a whole by being adhered by an adhesive or other adhesive means. Specifically, the region shown in the hatch of the separation portion 14 shown in FIG. 14 and the region shown in the hatch of the middle front portion 114 shown in FIG. 17 are adhered to each other (that is, the region shown in the hatch of the separation portion 14 and the middle front). An adhesive layer is provided between the area shown in the hatching of the portion 114), and similarly, the region shown in the hatching of the separating portion 44 shown in FIG. 14 and the region shown in the hatching of the middle back portion 144 shown in FIG. (That is, an adhesive layer is provided between the region indicated by the hatching of the separation portion 44 and the region indicated by the hatching of the middle back portion 144). As a result, the sleeve-shaped portion 105 of the outer box portion B is provided along the outer surface of the sleeve-shaped portion 5 in the inner box portion A, and for example, the front portion 110 is provided along the outer surface of the front portion 10. The side surface portion 120 is provided along the outer surface of the side surface portion 20, the side surface portion 130 is provided along the outer surface of the side surface portion 30, and the back surface portion 140 is provided along the outer surface of the back surface portion 40. It is provided. As for the adhesive force of the adhesive, by pulling up the middle front portion 114 diagonally upward on the front side, the cut lines 116Ka and 116Kb are broken and the cut lines 16Ka and 16Kb are also broken, so that the separation portion 14 is separated from the front portion 10. However, it is set to follow the middle front portion 114 in a state of being adhered to the middle front portion 114. Similarly, the adhesive strength of the adhesive is such that the cut line 146Ka and 146Kb are broken and the cut lines 46Ka and 46Kb are also broken by pulling the middle back portion 144 diagonally upward on the back side, and the separation portion 44 is the back portion. It is set to follow the middle back portion 144 in a state of being separated from the 40 and adhered to the middle back portion 144.

また、内箱部Ａと外箱部Ｂとが接着された状態では、内箱部Ａの下端と外箱部Ｂの下端とが同じ高さになるように形成されている。なお、内箱部Ａと外箱部Ｂとは、分離部１４、４４の箇所以外は互いに接着されていない。ただし、スリーブ状部５、１０５を筒状にして包装箱Ｐを立体状に組み立てた状態では、連結部Ｗ１が開口部Ｋ４０に入り込み、連結部Ｗ１の少なくとも先端（つまり、角部）は、開口部Ｋ４０内に設けられ、また、連結部Ｗ２が開口部Ｋ５０に入り込み、連結部Ｗ２の少なくとも先端（つまり、角部）は、開口部Ｋ５０内に設けられている。 Further, in a state where the inner box portion A and the outer box portion B are adhered to each other, the lower end of the inner box portion A and the lower end of the outer box portion B are formed to have the same height. The inner box portion A and the outer box portion B are not adhered to each other except for the separated portions 14 and 44. However, in a state where the sleeve-shaped portions 5 and 105 are formed into a tubular shape and the packaging box P is assembled in a three-dimensional shape, the connecting portion W1 enters the opening K40, and at least the tip (that is, the corner portion) of the connecting portion W1 is opened. The connecting portion W2 is provided in the opening K40, and at least the tip end (that is, the corner portion) of the connecting portion W2 is provided in the opening K50.

すなわち、包装箱Ｐを立体状に組み立てた状態では、連結部Ｗ１は、正面視においては、図７に示すように、側面部１２０に重なった状態となり、連結部Ｗ１は、右側面視においては、図８に示すように、正面部１１０に重なった状態となって、連結部Ｗ１が開口部Ｋ４０に入り込んだ状態となる。 That is, when the packaging box P is assembled in a three-dimensional manner, the connecting portion W1 is in a state of overlapping the side surface portion 120 in the front view as shown in FIG. 7, and the connecting portion W1 is in a state of overlapping the side surface portion 120 in the right side view. As shown in FIG. 8, the connecting portion W1 is in a state of being overlapped with the front portion 110, and the connecting portion W1 is in a state of entering the opening K40.

より具体的には、図７のＡ１−Ａ１位置の断面は図１１に示すようになり、連結部Ｗ１が、折れ線Ｃ３の位置を先端として二つ折りの状態となって開口部Ｋ４０内に入り込んで連結部Ｗ１が開口部Ｋ４０に係合した状態となり、図７のＡ１−Ａ１位置の断面における平面視では、図１１に示すように、連結部Ｗ１が開口部Ｋ４０の底面Ｋ４０−１に重なった状態となる（つまり、連結部Ｗ１が、開口部Ｋ４０の底面の厚み領域と重なる）。なお、連結部Ｗ１が二つ折りの状態となるので、切欠部Ｋ１０、Ｋ１２を挟んだ両側の辺部（上下方向の辺部）は、互いに接した状態となる。なお、包装箱Ｐを立体状に組み立てた状態では、開口部Ｋ４０の横断面は、図１１に示すように略Ｌ字状となっている。 More specifically, the cross section of the A1-A1 position in FIG. 7 is as shown in FIG. 11, and the connecting portion W1 is folded in half with the position of the polygonal line C3 as the tip and enters the opening K40. The connecting portion W1 was engaged with the opening K40, and in the plan view of the cross section at the position A1-A1 in FIG. 7, the connecting portion W1 overlapped the bottom surface K40-1 of the opening K40 as shown in FIG. The state is reached (that is, the connecting portion W1 overlaps with the thickness region of the bottom surface of the opening K40). Since the connecting portion W1 is folded in half, the side portions (side portions in the vertical direction) on both sides of the cutout portions K10 and K12 are in contact with each other. In the state where the packaging box P is assembled in a three-dimensional shape, the cross section of the opening K40 is substantially L-shaped as shown in FIG.

なお、高さ方向において、開口部Ｋ４０の上端は、連結部Ｗ１の上端よりも上側にあり、開口部Ｋ４０の下端は、連結部Ｗ１の下端よりも下側にあるため、開口部Ｋ４０の上端と連結部Ｗ１の上端の間には、わずかな隙間があり、開口部Ｋ４０の下端と連結部Ｗ１の下端の間には、わずかな隙間があるが、連結部Ｗ１の上端が開口部Ｋ４０の上端に接するか、あるいは、連結部Ｗ１の下端が開口部Ｋ４０の下端に接していてもよい。 In the height direction, the upper end of the opening K40 is above the upper end of the connecting portion W1, and the lower end of the opening K40 is below the lower end of the connecting portion W1, so that the upper end of the opening K40 is located. There is a slight gap between the upper end of the connecting portion W1 and the lower end of the opening K40, and there is a slight gap between the lower end of the opening K40 and the lower end of the connecting portion W1, but the upper end of the connecting portion W1 is the opening K40. It may be in contact with the upper end, or the lower end of the connecting portion W1 may be in contact with the lower end of the opening K40.

このように、連結部Ｗ１が開口部Ｋ４０に入り込んでいるので、内箱部Ａが外箱部Ｂに対して下方に移動しようとしても、連結部Ｗ１の下端が開口部Ｋ４０の下端に接して、内箱部Ａが下方に移動するのを妨げることができる。また、内箱部Ａが外箱部Ｂに対して上方に移動しようとしても、連結部Ｗ１の上端が開口部Ｋ４０の上端に接して、内箱部Ａが上方に移動するのを妨げることができる。つまり、連結部Ｗ１と開口部Ｋ４０により、内箱部Ａが外箱部Ｂに対して上下に移動するのを規制している。 In this way, since the connecting portion W1 has entered the opening K40, even if the inner box portion A tries to move downward with respect to the outer box portion B, the lower end of the connecting portion W1 comes into contact with the lower end of the opening K40. , The inner box portion A can be prevented from moving downward. Further, even if the inner box portion A tries to move upward with respect to the outer box portion B, the upper end of the connecting portion W1 may come into contact with the upper end of the opening K40 to prevent the inner box portion A from moving upward. can. That is, the connecting portion W1 and the opening portion K40 regulate the inner box portion A from moving up and down with respect to the outer box portion B.

また、連結部Ｗ１は、開口部Ｋ４０に入り込んでいるが、図１１に示すように、連結部Ｗ１は、正面部１１０の外側の面の延長面１１０Ｒと、側面部１２０の外側の面の延長面１２０Ｒがなす仮想角部Ｒ１からは突出していない（つまり、連結部Ｗ１は、延長面１１０Ｒからも突出してないとともに、延長面１２０Ｒからも突出していない）ので、連結部Ｗ１が突出して邪魔になることがなく、さらには、図１１に示すように、連結部Ｗ１の先端は、外箱部Ｂの外周面から突出しておらず、連結部Ｗ１が邪魔になることがない。なお、正面部１１０と側面部１２０の角部の位置の外箱部Ｂの外周面は、連結部Ｌ４０ａ、Ｌ４０ｂの外周面により構成され、正面部１１０と側面部１２０がなす角部における開口部Ｋ４０が形成された領域以外の領域の外周面（つまり、連結部Ｌ４０ａ、Ｌ４０ｂの外周面）は、図１１に示すように略円弧状の面（つまり、円柱形状の周面の一部をなす面）により形成されている。つまり、角部の位置の外周面は、仮想角部Ｒ１よりも内側となる。 Further, the connecting portion W1 is inserted into the opening K40, but as shown in FIG. 11, the connecting portion W1 is an extension surface 110R of the outer surface of the front surface portion 110 and an extension of the outer surface of the side surface portion 120. Since the connecting portion W1 does not protrude from the virtual corner portion R1 formed by the surface 120R (that is, the connecting portion W1 does not protrude from the extension surface 110R and also does not protrude from the extension surface 120R), the connecting portion W1 protrudes and becomes an obstacle. Further, as shown in FIG. 11, the tip of the connecting portion W1 does not protrude from the outer peripheral surface of the outer box portion B, and the connecting portion W1 does not get in the way. The outer peripheral surface of the outer box portion B at the corners of the front portion 110 and the side surface portion 120 is composed of the outer peripheral surfaces of the connecting portions L40a and L40b, and the opening portion at the corner portion formed by the front portion 110 and the side surface portion 120. The outer peripheral surface of the region other than the region where K40 is formed (that is, the outer peripheral surface of the connecting portions L40a and L40b) forms a substantially arcuate surface (that is, a part of the peripheral surface of the cylindrical shape) as shown in FIG. It is formed by a surface). That is, the outer peripheral surface at the position of the corner portion is inside the virtual corner portion R1.

なお、外箱部Ｂを展開した状態における開口部Ｋ４０の横方向の幅は、内箱部Ａを展開した状態における切欠部Ｋ１０、Ｋ１２の横方向の幅と略同一であるので、上記のように、連結部Ｗ１が開口部Ｋ４０に入り込んで開口部Ｋ４０の底面の厚み領域と重なるとともに、連結部Ｗ１が仮想角部Ｒ１から突出しないように形成することができる。 The lateral width of the opening K40 in the expanded state of the outer box portion B is substantially the same as the lateral width of the cutout portions K10 and K12 in the expanded state of the inner box portion A, as described above. In addition, the connecting portion W1 can be formed so as to enter the opening K40 and overlap with the thickness region of the bottom surface of the opening K40, and the connecting portion W1 does not protrude from the virtual corner portion R1.

また、連結部Ｗ２は、右側面視においては、図９に示すように、背面部１４０に重なった状態となり、連結部Ｗ２は、背面視においては、図１０に示すように、側面部１２０に重なった状態となって、連結部Ｗ２が開口部Ｋ５０に入り込んだ状態となる。 Further, the connecting portion W2 is in a state of overlapping the back surface portion 140 as shown in FIG. 9 in the right side view, and the connecting portion W2 is placed on the side surface portion 120 as shown in FIG. 10 in the rear view. In the overlapping state, the connecting portion W2 is in a state of entering the opening K50.

また、より具体的には、図１０のＡ２−Ａ２断面は図１２に示すようになり、連結部Ｗ２が、折れ線Ｃ４の位置を先端として二つ折りの状態となって開口部Ｋ５０内に入り込んで、連結部Ｗ２が開口部Ｋ５０に係合した状態となり、図１０のＡ２−Ａ２位置の断面における平面視では、連結部Ｗ２が開口部Ｋ５０の底面Ｋ５０−１に重なった状態となる（つまり、連結部Ｗ２が、開口部Ｋ５０の底面の厚み領域と重なる）。なお、連結部Ｗ２が二つ折りの状態となるので、切欠部Ｋ２０、Ｋ２２を挟んだ両側の辺部（上下方向の辺部）は、互いに接した状態となる。なお、包装箱Ｐを立体状に組み立てた状態では、開口部Ｋ５０の横断面は、図１２に示すように略Ｌ字状となっている。 More specifically, the cross section of A2-A2 in FIG. 10 is as shown in FIG. 12, and the connecting portion W2 is folded in half with the position of the polygonal line C4 as the tip and enters the opening K50. , The connecting portion W2 is engaged with the opening K50, and the connecting portion W2 is overlapped with the bottom surface K50-1 of the opening K50 in a plan view in the cross section of the A2-A2 position in FIG. 10 (that is,). The connecting portion W2 overlaps with the thickness region of the bottom surface of the opening K50). Since the connecting portion W2 is folded in half, the side portions (side portions in the vertical direction) on both sides of the cutout portions K20 and K22 are in contact with each other. In the state where the packaging box P is assembled in a three-dimensional shape, the cross section of the opening K50 is substantially L-shaped as shown in FIG.

なお、高さ方向において、開口部Ｋ５０の上端は、連結部Ｗ２の上端よりも上側にあり、開口部Ｋ５０の下端は、連結部Ｗ２の下端よりも下側にあるため、開口部Ｋ５０の上端と連結部Ｗ２の上端の間には、わずかな隙間があり、開口部Ｋ５０の下端と連結部Ｗ２の下端の間には、わずかな隙間があるが、連結部Ｗ２の上端が開口部Ｋ５０の上端に接するか、あるいは、連結部Ｗ２の下端が開口部Ｋ５０の下端に接していてもよい。 In the height direction, the upper end of the opening K50 is above the upper end of the connecting portion W2, and the lower end of the opening K50 is below the lower end of the connecting portion W2. There is a slight gap between the upper end of the connecting portion W2 and the lower end of the opening K50, and there is a slight gap between the lower end of the opening K50 and the lower end of the connecting portion W2, but the upper end of the connecting portion W2 is the opening K50. It may be in contact with the upper end, or the lower end of the connecting portion W2 may be in contact with the lower end of the opening K50.

このように、連結部Ｗ２が開口部Ｋ５０に入り込んでいるので、内箱部Ａが外箱部Ｂに対して下方に移動しようとしても、連結部Ｗ２の下端が開口部Ｋ５０の下端に接して、内箱部Ａが下方に移動するのを妨げることができる。また、内箱部Ａが外箱部Ｂに対して上方に移動しようとしても、連結部Ｗ２の上端が開口部Ｋ５０の上端に接して、内箱部Ａが上方に移動するのを妨げることができる。つまり、連結部Ｗ２と開口部Ｋ５０により、内箱部Ａが外箱部Ｂに対して上下に移動するのを規制している。 In this way, since the connecting portion W2 has entered the opening K50, even if the inner box portion A tries to move downward with respect to the outer box portion B, the lower end of the connecting portion W2 comes into contact with the lower end of the opening K50. , The inner box portion A can be prevented from moving downward. Further, even if the inner box portion A tries to move upward with respect to the outer box portion B, the upper end of the connecting portion W2 may come into contact with the upper end of the opening K50 to prevent the inner box portion A from moving upward. can. That is, the connecting portion W2 and the opening portion K50 restrict the inner box portion A from moving up and down with respect to the outer box portion B.

また、連結部Ｗ２は、開口部Ｋ５０に入り込んでいるが、図１２に示すように、連結部Ｗ２は、背面部１４０の外側の面の延長面１４０Ｒと、側面部１２０の外側の面の延長面１２０Ｒがなす仮想角部Ｒ２からは突出していない（つまり、連結部Ｗ２は、延長面１４０Ｒからも突出してないとともに、延長面１２０Ｒからも突出していない）ので、連結部Ｗ２が突出して邪魔になることがなく、さらには、図１２に示すように、連結部Ｗ２の先端は、外箱部Ｂの外周面から突出しておらず、連結部Ｗ２が邪魔になることがない。なお、背面部１４０と側面部１２０の角部の位置の外箱部Ｂの外周面は、連結部Ｌ５０ａ、Ｌ５０ｂの外周面により構成され、背面部１４０と側面部１２０がなす角部における開口部Ｋ５０が形成された領域以外の領域の外周面（つまり、連結部Ｌ５０ａ、Ｌ５０ｂの外周面）は、図１２に示すように略円弧状の面（つまり、円柱形状の周面の一部をなす面）により形成されている。つまり、角部の位置の外周面は、仮想角部Ｒ２よりも内側となる。 Further, the connecting portion W2 is inserted into the opening K50, but as shown in FIG. 12, the connecting portion W2 is an extension surface 140R of the outer surface of the back surface portion 140 and an extension of the outer surface of the side surface portion 120. Since the connecting portion W2 does not protrude from the virtual corner portion R2 formed by the surface 120R (that is, the connecting portion W2 does not protrude from the extension surface 140R and also does not protrude from the extension surface 120R), the connecting portion W2 protrudes and becomes an obstacle. Further, as shown in FIG. 12, the tip of the connecting portion W2 does not protrude from the outer peripheral surface of the outer box portion B, and the connecting portion W2 does not get in the way. The outer peripheral surface of the outer box portion B at the corners of the back surface portion 140 and the side surface portion 120 is composed of the outer peripheral surfaces of the connecting portions L50a and L50b, and the opening portion at the corner portion formed by the back surface portion 140 and the side surface portion 120. The outer peripheral surface of the region other than the region where the K50 is formed (that is, the outer peripheral surface of the connecting portions L50a and L50b) forms a substantially arcuate surface (that is, a part of the peripheral surface of the cylindrical shape) as shown in FIG. It is formed by a surface). That is, the outer peripheral surface at the position of the corner portion is inside the virtual corner portion R2.

なお、外箱部Ｂを展開した状態における開口部Ｋ５０の横方向の幅は、内箱部Ａを展開した状態における切欠部Ｋ２０、Ｋ２２の横方向の幅と略同一であるので、上記のように、連結部Ｗ２が開口部Ｋ５０の底面の厚み領域と重なるとともに、連結部Ｗ２が仮想角部Ｒ１から突出しないように形成することができる。 The lateral width of the opening K50 in the expanded state of the outer box portion B is substantially the same as the lateral width of the cutout portions K20 and K22 in the expanded state of the inner box portion A, as described above. In addition, the connecting portion W2 can be formed so as to overlap the thickness region of the bottom surface of the opening K50 and the connecting portion W2 does not protrude from the virtual corner portion R1.

以上のように、内箱部Ａは外箱部Ｂの内側に収納した状態となっていて、内箱部Ａの底面部５０以外は外箱部Ｂに被覆された状態となっている。つまり、外箱部Ｂの下端の高さ方向の位置は、内箱部Ａの下端の高さ方向の位置と略同一であり、蓋部１７０、１８０を封止した状態では内箱部Ａにおいては底面部５０のみが露出している。 As described above, the inner box portion A is stored inside the outer box portion B, and the outer box portion B is covered with the parts other than the bottom surface portion 50 of the inner box portion A. That is, the position of the lower end of the outer box portion B in the height direction is substantially the same as the position of the lower end of the inner box portion A in the height direction. Only the bottom surface 50 is exposed.

なお、上記構成の包装箱Ｐは、内箱部Ａが上記のように折り畳むことができ、また、外箱部Ｂがスリーブ状部１０５を有し、全体に略スリーブ状を呈しているので、包装箱Ｐの状態においても平板状に折り畳むことができ、正面部１１０を側面部１３０に対して略平行になるようにし、かつ、側面部１２０を背面部１４０に対して略平行になるようにする
ことにより、図２３に示すように平板状に折り畳むことができる。 In the packaging box P having the above configuration, the inner box portion A can be folded as described above, and the outer box portion B has a sleeve-shaped portion 105, so that the packaging box P has a substantially sleeve-like shape as a whole. Even in the state of the packaging box P, it can be folded into a flat plate shape so that the front portion 110 is substantially parallel to the side surface portion 130 and the side surface portion 120 is substantially parallel to the back surface portion 140. By doing so, it can be folded into a flat plate shape as shown in FIG. 23.

なお、上記内箱部Ａ及び外箱部Ｂにおいて、各折れ線の箇所には、予め罫線が形成されている。 In the inner box portion A and the outer box portion B, a ruled line is formed in advance at each polygonal line.

上記構成の包装箱Ｐの製造工程について説明する。まず、展開状態の内箱部Ａと外箱部Ｂとを製造する。 The manufacturing process of the packaging box P having the above configuration will be described. First, the inner box portion A and the outer box portion B in the unfolded state are manufactured.

次に、外箱部Ｂの内側の面に内箱部Ａの外側の面を接着させる（第１接着工程）。つまり、展開状態の外箱部Ｂの内側の面を上側にして、中正面部１１４における分離部１４との接着領域と中背面部１４４における分離部４４との接着領域に接着剤を塗布して、展開状態の内箱部Ａを図２０に示すように重ねる。これにより、分離部１４と中正面部１１４が接着され、分離部４４と中背面部１４４が接着される。その際、外箱部Ｂのスリーブ状部１０５の下辺と内箱部Ａのスリーブ状部５の下辺とが略一致する（一致するとしてもよい）ようにし、また、外箱部Ｂと内箱部Ａとにおいて、折れ線Ｃ４と折れ線Ｃ１３を一致させる。なお、スリーブ状部５とスリーブ状部１０５において、互いに対応する部材の横方向の長さは、原則として外箱部Ｂの方が若干長く形成されているので、図２０に示すように、折れ線Ｃ１２は、折れ線Ｃ３に対して外側にずれ、折れ線Ｃ１１は折れ線Ｃ２に対して外側にずれる。なお、外箱部Ｂのスリーブ状部１０５の下辺と内箱部Ａのスリーブ状部５の下辺とを略一致させるので、内箱部が外箱部の下方から見えてしまい見栄えが悪くなることがない。 Next, the outer surface of the inner box portion A is adhered to the inner surface of the outer box portion B (first bonding step). That is, with the inner surface of the outer box portion B in the unfolded state facing upward, the adhesive is applied to the adhesive region between the inner front portion 114 and the separation portion 14 and the inner back portion 144 between the separation portion 44 and the adhesion region. , The inner box portion A in the unfolded state is overlapped as shown in FIG. As a result, the separated portion 14 and the middle front portion 114 are adhered to each other, and the separated portion 44 and the middle back portion 144 are adhered to each other. At that time, the lower side of the sleeve-shaped portion 105 of the outer box portion B and the lower side of the sleeve-shaped portion 5 of the inner box portion A are made to substantially match (may be matched), and the outer box portion B and the inner box are made to coincide with each other. In the part A, the polygonal line C4 and the polygonal line C13 are made to coincide with each other. In the sleeve-shaped portion 5 and the sleeve-shaped portion 105, the lateral lengths of the members corresponding to each other are formed to be slightly longer in the outer box portion B in principle, and therefore, as shown in FIG. 20, a polygonal line is formed. C12 is displaced outward with respect to the polygonal line C3, and the polygonal line C11 is displaced outward with respect to the polygonal line C2. Since the lower side of the sleeve-shaped portion 105 of the outer box portion B and the lower side of the sleeve-shaped portion 5 of the inner box portion A are substantially aligned with each other, the inner box portion can be seen from below the outer box portion, resulting in poor appearance. There is no.

次に、内箱部Ａの底面部５０を構成する各部をスリーブ状部５に対して内側に折り返し、さらに、第１片部６０の先端部６４を本体部６２に対して外側に折り返すとともに、第２片部７０の先端部７４を本体部７２に対して外側に折り返して、図２１に示す状態とする（第２折り返し工程）。つまり、第１片部６０を正面部１０との境界の折れ線を介して正面部１０側に折り返し、第２片部７０を側面部２０との境界の折れ線を介して側面部２０側に折り返し、第３片部８０を側面部３０との境界の折れ線を介して側面部３０側に折り返し、第４片部９０を背面部４０との境界の折れ線を介して背面部４０側に折り返し、さらに、先端部６４を本体部６２に対して折り返すとともに、先端部７４を本体部７２に対して折り返す。 Next, each portion constituting the bottom surface portion 50 of the inner box portion A is folded inward with respect to the sleeve-shaped portion 5, and the tip portion 64 of the first piece portion 60 is folded outward with respect to the main body portion 62. The tip portion 74 of the second piece portion 70 is folded outward with respect to the main body portion 72 to obtain the state shown in FIG. 21 (second folding step). That is, the first piece 60 is folded back toward the front surface 10 via the polygonal line at the boundary with the front surface 10, and the second piece 70 is folded back toward the side surface 20 via the polygonal line at the boundary with the side surface 20. The third piece 80 is folded back toward the side surface 30 via the polygonal line at the boundary with the side surface 30, the fourth piece 90 is folded back toward the back surface 40 via the polygonal line at the boundary with the back surface 40, and further. The tip portion 64 is folded back with respect to the main body portion 62, and the tip portion 74 is folded back with respect to the main body portion 72.

次に、先端部６４の領域に接着剤を塗布して（第１接着剤塗布工程）、側面部１３０を折れ線Ｃ１１を介して正面部１１０の側に内側に折り返す（折り返し工程）ことにより、側面部３０を折れ線Ｃ１を介して正面部１０側に折り返し、図２２に示す状態とする。すると、先端部６４が第３片部８０（具体的には本体部８２ａ）に接着される。なお、先端部６４の代わりに、第３片部８０における先端部６４との接着領域に接着剤を塗布してもよい。 Next, an adhesive is applied to the region of the tip portion 64 (first adhesive application step), and the side surface portion 130 is folded back inward toward the front portion 110 via the broken line C11 (folding step). The portion 30 is folded back to the front portion 10 side via the folding line C1 so as to be in the state shown in FIG. 22. Then, the tip portion 64 is adhered to the third piece portion 80 (specifically, the main body portion 82a). Instead of the tip portion 64, the adhesive may be applied to the adhesive region of the third piece portion 80 with the tip portion 64.

次に、先端部７４の領域と、糊代部４９の領域と、糊代部１４９の領域に接着剤を塗布して（第２接着剤塗布工程）、背面部１４０を折れ線Ｃ１３を介して側面部１２０の側に内側に折り返すことにより、背面部４０を折れ線Ｃ４を介して側面部２０側に折り返し、図２３に示す状態とする。すると、先端部７４と第４片部９０が接着され、糊代部４９が背面部４０（具体的には、左背面部４２ｂ）に接着され、糊代部１４９が側面部１３０に接着される（第２接着工程）。 Next, an adhesive is applied to the region of the tip portion 74, the region of the glue margin portion 49, and the region of the glue margin portion 149 (second adhesive application step), and the back surface portion 140 is side surface via the polygonal line C13. By folding back inward to the side of the portion 120, the back surface portion 40 is folded back to the side surface portion 20 side via the folding line C4, and the state shown in FIG. 23 is obtained. Then, the tip portion 74 and the fourth piece portion 90 are adhered, the glue margin portion 49 is adhered to the back surface portion 40 (specifically, the left back surface portion 42b), and the glue margin portion 149 is adhered to the side surface portion 130. (Second bonding step).

なお、先端部７４の代わりに、第４片部９０における先端部７４との接着領域に接着剤を塗布してもよく、糊代部４９の代わりに、背面部４０における糊代部４９との接着領域に接着剤を塗布してもよく、また、糊代部１４９の代わりに、側面部１３０における糊代部１４９との接着領域に接着剤を塗布してもよい。以上のようにして、包装箱Ｐが製造される。なお、上記の製造は、組立て装置により自動で製造される。 In addition, instead of the tip portion 74, an adhesive may be applied to the adhesive region with the tip portion 74 in the fourth piece portion 90, and instead of the glue margin portion 49, the glue margin portion 49 on the back surface portion 40 may be applied. An adhesive may be applied to the adhesive region, or instead of the adhesive margin portion 149, the adhesive may be applied to the adhesive region with the glue margin portion 149 on the side surface portion 130. As described above, the packaging box P is manufactured. The above manufacturing is automatically manufactured by the assembly device.

なお、背面部４０を側面部２０に対して折り曲げた際には、分離部４４が中背面部１４４に接着されているので、側面部２０が正面部１０側に押されるが、分離部１４も中正面部１１４に接着されているので、側面部２０は横方向には移動できず、結果として、開口部Ｋ５０に連結部Ｗ２が入り込むことになる。 When the back surface portion 40 is bent with respect to the side surface portion 20, since the separation portion 44 is adhered to the middle back surface portion 144, the side surface portion 20 is pushed toward the front surface portion 10, but the separation portion 14 is also Since it is adhered to the middle front portion 114, the side surface portion 20 cannot move laterally, and as a result, the connecting portion W2 enters the opening K50.

上記の製造方法によれば、上記のように、外箱部Ｂと内箱部Ａを重ねて接着した後に、接着剤を塗布した後に折り返す工程を２回行う（つまり、図２１の状態から図２２の状態への工程と、図２２の状態から図２３の状態への工程）ことにより製造することができ、少ない工程で製造できるので、低コストで容易に包装箱Ｐを製造することができる。 According to the above manufacturing method, as described above, the steps of overlapping and adhering the outer box portion B and the inner box portion A, applying the adhesive, and then folding back are performed twice (that is, from the state of FIG. 21). It can be manufactured by the step to the state of 22 and the step from the state of FIG. 22 to the state of FIG. 23), and since it can be manufactured in a small number of steps, the packaging box P can be easily manufactured at low cost. ..

なお、上記の製造工程において、第４片部９０を背面部４０側に折り返し、第２片部７０を側面部２０側に折り返し、さらに、先端部７４を本体部７２に対して折り返す工程は、側面部１３０を正面部１１０の側に折り返して、先端部６４を第３片部８０に接着した後で、先端部７４の領域と、糊代部４９の領域と、糊代部１４９の領域に接着剤を塗布する前に行ってもよい。その場合、上記折返し工程では、第１片部６０と第３片部８０を折り返して、先端部６４を折り返し、その後、先端部６４に接着剤を塗布することになる（第１折り返し・接着剤塗布工程）。 In the above manufacturing process, the step of folding the fourth piece 90 toward the back surface 40, folding the second piece 70 toward the side surface 20, and further folding the tip 74 with respect to the main body 72 is After the side surface portion 130 is folded back toward the front portion 110 and the tip portion 64 is adhered to the third piece portion 80, the region of the tip portion 74, the region of the glue margin portion 49, and the region of the glue margin portion 149 are formed. It may be done before applying the adhesive. In that case, in the folding step, the first piece 60 and the third piece 80 are folded back, the tip portion 64 is folded back, and then the adhesive is applied to the tip portion 64 (first folding / adhesive). Coating process).

また、先端部６４への接着剤の塗布は、第１片部６０を折り返し先端部６４を折り返した状態で行うとしたが、図２０の状態で先端部６４に接着剤を塗布した後に、第１片部６０を図２１に示す状態としてもよい（第１接着剤塗布・折り返し工程）。図２０の状態で先端部６４に接着剤を塗布した状態で第１片部６０を図２１に示す状態とするのは、第３片部８０を図２１に示す状態にするのと同時に行ってもよい。 Further, the adhesive is applied to the tip portion 64 in a state where the first piece portion 60 is folded back and the tip portion 64 is folded back, but after applying the adhesive to the tip portion 64 in the state of FIG. 20, the first piece portion 60 is applied. One piece 60 may be in the state shown in FIG. 21 (first adhesive application / folding step). In the state shown in FIG. 20, the state in which the adhesive is applied to the tip portion 64 and the first piece portion 60 is in the state shown in FIG. 21 is performed at the same time as the third piece portion 80 is in the state shown in FIG. May be good.

また、先端部７４への接着剤の塗布は、第２片部７０を折り返し先端部７４を折り返した状態で行うとしたが、図２０の状態で先端部７４に接着剤を塗布した後に、第２片部７０を図２１に示す状態としてもよい（第２接着剤塗布・折り返し工程）。なお、図２１の状態で先端部７４に接着剤を塗布した後に、第２片部７０を図２１に示す状態とするのは、側面部１３０を正面部１１０の側に折り返して、先端部６４を第３片部８０に接着した後でもよい（第２接着剤塗布・折り返し工程）。また、図２０の状態で先端部７４に接着剤を塗布した状態で第２片部７０を図２１に示す状態とするのは、第４片部９０を図２１に示す状態にするのと同時に行ってもよい。 Further, the adhesive is applied to the tip portion 74 in a state where the second piece 70 is folded back and the tip portion 74 is folded back, but after applying the adhesive to the tip portion 74 in the state of FIG. 20, the second piece portion 70 is applied. The two pieces 70 may be in the state shown in FIG. 21 (second adhesive application / folding step). After applying the adhesive to the tip portion 74 in the state of FIG. 21, the second piece portion 70 is in the state shown in FIG. 21 by folding the side surface portion 130 toward the front portion 110 and the tip portion 64. May be after adhering to the third piece portion 80 (second adhesive application / folding step). Further, in the state of FIG. 20, when the adhesive is applied to the tip portion 74, the second piece portion 70 is in the state shown in FIG. 21 at the same time as the fourth piece portion 90 is in the state shown in FIG. You may go.

次に、包装箱Ｐを使用する際に、包装箱Ｐを組み立てる。つまり、スリーブ状部５、１０５を筒状に広げるとともに、第３片部８０を下方に押し込むことにより底面部５０が形成されて、包装箱Ｐが立体状に組み立てられる。すなわち、外箱部Ｂにおける正面部１１０と背面部１４０とが互いに平行になり、側面部１２０と側面部１３０とが互いに平行になるようにするとともに、内箱部Ａにおける正面部１０と背面部４０とが互いに平行になり、側面部２０と側面部３０とが互いに平行になるようにし、底面部５０がスリーブ状部５、１０５に対して直角になるようにすることにより包装箱Ｐが立体状に組み立てられる。包装箱Ｐを立体状に組み立てた場合には、側面部１２０が正面部１１０及び背面部１４０に対して直角になり、側面部２０が正面部１０及び背面部４０に直角になる。 Next, when using the packaging box P, the packaging box P is assembled. That is, the sleeve-shaped portions 5 and 105 are expanded in a cylindrical shape, and the bottom surface portion 50 is formed by pushing the third piece portion 80 downward, so that the packaging box P is assembled in a three-dimensional shape. That is, the front portion 110 and the back portion 140 in the outer box portion B are parallel to each other, the side surface portions 120 and the side surface portions 130 are parallel to each other, and the front portion 10 and the back surface portion in the inner box portion A are parallel to each other. The packaging box P is three-dimensional by making the side surface portion 20 and the side surface portion 30 parallel to each other and the bottom surface portion 50 perpendicular to the sleeve-shaped portions 5 and 105. Assembled into a shape. When the packaging box P is assembled in a three-dimensional manner, the side surface portion 120 is perpendicular to the front portion 110 and the back surface portion 140, and the side surface portion 20 is perpendicular to the front surface portion 10 and the back surface portion 40.

このように、包装箱Ｐを立体状に組み立てた場合でも、分離部１４が中正面部１１４に接着されるとともに、分離部４４が中背面部１４４に接着されているので、正面部１０と背面部４０が側面部２０に対して直角に折り曲げられた状態では、正面部１０と背面部４０により側面部２０が押された状態となり、結果として、連結部Ｗ１が開口部Ｋ４０に入り込んだ状態となり、連結部Ｗ２が開口部Ｋ５０に入り込んだ状態となる。 In this way, even when the packaging box P is assembled in a three-dimensional manner, the separation portion 14 is adhered to the middle front portion 114 and the separation portion 44 is adhered to the middle back portion 144, so that the front portion 10 and the back surface portion 10 are adhered to each other. When the portion 40 is bent at a right angle to the side surface portion 20, the side surface portion 20 is pushed by the front surface portion 10 and the back surface portion 40, and as a result, the connecting portion W1 enters the opening portion K40. , The connecting portion W2 is in a state of being inserted into the opening K50.

そして、図２４に示すように、包装箱Ｐの上方から複数の商品（被収納物）Ｇを内箱部Ａ内に収納する。なお、蓋部１７０、１８０及びフラップ部１６０、１９０は、予め上方に立設した状態になっていて、外箱部Ｂの上方が開口した状態になっているので、商品Ｇはそのまま包装箱Ｐの上方から収納すればよい。その後、フラップ部１６０、１９０を閉じた後に蓋部１７０、１８０を閉じて、図２５に示すように、接着テープ（接着手段）Ｔを外箱部Ｂの正面部１１０から上面を経て背面部１４０側にまで接着させることにより、蓋部１７０、１８０を封止する。 Then, as shown in FIG. 24, a plurality of products (collected items) G are stored in the inner box portion A from above the packaging box P. Since the lid portions 170 and 180 and the flap portions 160 and 190 are in a state of being erected upward in advance and the upper part of the outer box portion B is in an open state, the product G can be used as it is in the packaging box P. It can be stored from above. Then, after closing the flap portions 160 and 190, the lid portions 170 and 180 are closed, and as shown in FIG. 25, the adhesive tape (adhesive means) T is applied from the front portion 110 of the outer box portion B through the upper surface to the back portion 140. The lids 170 and 180 are sealed by adhering to the side.

以上のようにして、商品Ｇを包装箱Ｐに包装したら、商品Ｇを収納した包装箱Ｐを商品Ｇを陳列する場所に搬送する。 After the product G is packaged in the packaging box P as described above, the packaging box P containing the product G is transported to the place where the product G is displayed.

その後、商品を陳列する場合には、外箱部Ｂを内箱部Ａから分離する。すなわち、正面側の切目線１６Ｋａ、１６Ｋｂ、１１６Ｋａ、１１６Ｋｂと背面側の切目線４６Ｋａ、４６Ｋｂ、１４６Ｋａ、１４６Ｋｂを破断して、外箱部Ｂを内箱部Ａから分離する。 After that, when displaying the products, the outer box portion B is separated from the inner box portion A. That is, the cut lines 16Ka, 16Kb, 116Ka, 116Kb on the front side and the cut lines 46Ka, 46Kb, 146Ka, 146Kb on the back side are broken to separate the outer box portion B from the inner box portion A.

具体的には、正面側については、中正面部１１４の下端を指でつかんで、正面側斜め上方に引き上げることにより、図２６に示すように、正面側の切目線１６Ｋａ、１６Ｋｂ、１１６Ｋａ、１１６Ｋｂが破断して、分離部１４が右正面部１２ａ及び左正面部１２ｂから分離するとともに、中正面部１１４が右正面部１１２ａ及び左正面部１１２ｂから分離する。分離部１４と中正面部１１４が接着されているので、中正面部１１４を引き上げるのみで切目線１６Ｋａ、１６Ｋｂも破断する。なお、中正面部１１４と分離部１４の両方を指でつかんで引き上げてもよい。 Specifically, on the front side, by grasping the lower end of the middle front portion 114 with a finger and pulling it diagonally upward on the front side, as shown in FIG. 26, the cut lines on the front side are 16Ka, 16Kb, 116Ka, 116Kb. Is broken, and the separation portion 14 is separated from the right front portion 12a and the left front portion 12b, and the middle front portion 114 is separated from the right front portion 112a and the left front portion 112b. Since the separation portion 14 and the middle front portion 114 are adhered to each other, the cut lines 16Ka and 16Kb are also broken only by pulling up the middle front portion 114. In addition, you may grab both the middle front portion 114 and the separation portion 14 with your fingers and pull them up.

また、背面側については、中背面部１４４の下端を指でつかんで、背面側斜め上方に引き上げることにより、正面側の場合と同様に、背面側の切目線４６Ｋａ、４６Ｋｂ、１４６Ｋａ、１４６Ｋｂが破断して、分離部４４が右背面部４２ａ及び左背面部４２ｂから分離するとともに、中背面部１４４が右背面部１４２ａ及び左背面部１４２ｂから分離する。分離部４４と中背面部１４４が接着されているので、中背面部１４４を引き上げるのみで切目線４６Ｋａ、４６Ｋｂも破断する。なお、中背面部１４４と分離部４４の両方を指でつかんで引き上げてもよい。 On the back side, by grasping the lower end of the middle back portion 144 with a finger and pulling it diagonally upward on the back side, the cut lines 46Ka, 46Kb, 146Ka, and 146Kb on the back side are broken as in the case of the front side. Then, the separation portion 44 is separated from the right back surface portion 42a and the left back surface portion 42b, and the middle back surface portion 144 is separated from the right back surface portion 142a and the left back surface portion 142b. Since the separation portion 44 and the middle back portion 144 are adhered to each other, the cut lines 46Ka and 46Kb are also broken only by pulling up the middle back portion 144. In addition, you may grab both the middle back portion 144 and the separation portion 44 with your fingers and pull up.

すると、外箱部Ｂと接着している分離部１４、４４は内箱部Ａから分離しており、さらに、外箱部Ｂの切目線１１６Ｋａ、１１６Ｋｂ、１４６Ｋａ、１４６Ｋｂが破断しているので、図２７、図２８に示すように、側面部１２０を蓋部１７０に対して上方に回動させるとともに、側面部１３０を蓋部１８０に対して上方に回動させることができ（つまり、側面部１２０と側面部１３０を側面部１２０の下端と側面部１３０の下端の間隔が広がるように揺動させることができる）、外箱部Ｂを内箱部Ａに対して上方に引き上げるのが容易となる。特に、側面部１２０を蓋部１７０に対して上方に回動させることにより、連結部Ｗ１が開口部Ｋ４０に入り込んだ状態が解除されるとともに、連結部Ｗ２が開口部Ｋ５０に入り込んだ状態が解除されるので、外箱部Ｂを上方に引き上げることができる。 Then, the separation portions 14 and 44 that are adhered to the outer box portion B are separated from the inner box portion A, and further, the cut lines 116Ka, 116Kb, 146Ka, and 146Kb of the outer box portion B are broken. As shown in FIGS. 27 and 28, the side surface portion 120 can be rotated upward with respect to the lid portion 170, and the side surface portion 130 can be rotated upward with respect to the lid portion 180 (that is, the side surface portion). The 120 and the side surface 130 can be swung so that the distance between the lower end of the side surface 120 and the lower end of the side surface 130 is widened), and the outer box portion B can be easily pulled upward with respect to the inner box portion A. Become. In particular, by rotating the side surface portion 120 upward with respect to the lid portion 170, the state in which the connecting portion W1 has entered the opening K40 is released, and the state in which the connecting portion W2 has entered the opening K50 is released. Therefore, the outer box portion B can be pulled upward.

以上のように、外箱部Ｂを上方に引き上げることにより、図２９に示すように、商品Ｇを収納した状態で、かつ、分離部１４、４４が分離した状態の内箱部Ａが残るので、商品Ｇを収納した状態で内箱部Ａを陳列する。 As described above, by pulling up the outer box portion B upward, as shown in FIG. 29, the inner box portion A in the state where the product G is stored and the separation portions 14 and 44 are separated remains. , The inner box portion A is displayed with the product G stored.

以上のように、包装箱Ｐの組立てに際しては、スリーブ状部５、１０５を筒状に広げるとともに、第３片部８０を下方に押し込むことにより底面部５０が形成されて、包装箱Ｐが立体状に組み立てられ、スリーブ状部５、１０５を筒状に広げるのみで、連結部Ｗ１が開口部Ｋ４０に係合し、連結部Ｗ２が開口部Ｋ５０に係合するので、特許文献１の場合と異なり、内箱部を組み立てた状態で外箱部を被せる必要はなく、包装箱Ｐを容易に立体状に組み立てることができ、特に、包装箱Ｐの組立てに際して内箱部Ａと外箱部Ｂの係合が容易である。 As described above, when assembling the packaging box P, the sleeve-shaped portions 5 and 105 are expanded into a tubular shape, and the bottom portion 50 is formed by pushing the third piece portion 80 downward, so that the packaging box P is three-dimensional. Assembled in a shape, the connecting portion W1 engages with the opening K40 and the connecting portion W2 engages with the opening K50 only by expanding the sleeve-shaped portions 5 and 105 into a tubular shape. Unlike, it is not necessary to cover the outer box part with the inner box part assembled, and the packaging box P can be easily assembled in a three-dimensional shape. In particular, when assembling the packaging box P, the inner box part A and the outer box part B can be assembled. Is easy to engage.

また、包装箱Ｐによれば、内箱部Ａと外箱部Ｂが正面部１０、１１０と背面部４０、１４０において接着され、かつ、包装箱Ｐを立体状に組み立てた状態では、連結部Ｗ１、Ｗ２が開口部Ｋ４０、Ｋ５０に入り込んだ状態となっている（つまり、連結部Ｗ１が開口部Ｋ４０に入り込んだ状態であるとともに、連結部Ｗ２が開口部Ｋ５０に入り込んだ状態となっている）ので、収納される商品が重い場合や、内箱部Ａの高さが低い場合でも、内箱部Ａが外箱部Ｂから脱落するのを防止することができる。特に、内箱部Ａのように、スリーブ状部５の高さが低い場合には、スリーブ状部５とスリーブ状部１０５の接触面積が小さくので、スリーブ状部５の高さが高い場合に比べて、内箱部Ａが変形しやすいが、内箱部Ａと外箱部Ｂが接着されるとともに、連結部Ｗ１、Ｗ２が開口部Ｋ４０、Ｋ５０に入り込んだ状態となっているので、内箱部Ａが外箱部Ｂから脱落するのを防止することができる。 Further, according to the packaging box P, when the inner box portion A and the outer box portion B are adhered to each other at the front portions 10, 110 and the back portions 40, 140, and the packaging box P is assembled in a three-dimensional manner, the connecting portion. W1 and W2 are in the opening K40 and K50 (that is, the connecting portion W1 is in the opening K40 and the connecting portion W2 is in the opening K50. ) Therefore, even when the stored product is heavy or the height of the inner box portion A is low, it is possible to prevent the inner box portion A from falling off from the outer box portion B. In particular, when the height of the sleeve-shaped portion 5 is low as in the inner box portion A, the contact area between the sleeve-shaped portion 5 and the sleeve-shaped portion 105 is small, so that the height of the sleeve-shaped portion 5 is high. In comparison, the inner box portion A is easily deformed, but the inner box portion A and the outer box portion B are adhered to each other, and the connecting portions W1 and W2 are in a state of being inserted into the openings K40 and K50. It is possible to prevent the box portion A from falling off from the outer box portion B.

さらには、正面部１０及び側面部２０から連設された連結部Ｗ１が開口部Ｋ４０に入り込み、背面部４０及び側面部２０から連設された連結部Ｗ２が開口部Ｋ５０に入り込んで、特に、連結部Ｗ１、Ｗ２が二つ折りの状態で開口部Ｋ４０、Ｋ５０に入り込んでいるので、内箱部Ａを外箱部Ｂに係合させる部材である連結部Ｗ１、Ｗ２が、折れ曲がるおそれがなく、連結部Ｗ１、Ｗ２の強度を十分得ることができ、特許文献１の場合のように、連結部Ｗ１、Ｗ２が折れ曲がって開口部Ｋ４０、Ｋ５０から脱落するおそれがない。 Further, the connecting portion W1 serially connected from the front portion 10 and the side surface portion 20 enters the opening K40, and the connecting portion W2 serially connected from the back surface portion 40 and the side surface portion 20 enters the opening K50. Since the connecting portions W1 and W2 enter the openings K40 and K50 in a folded state, there is no possibility that the connecting portions W1 and W2, which are members for engaging the inner box portion A with the outer box portion B, will be bent. Sufficient strength can be obtained for the connecting portions W1 and W2, and there is no possibility that the connecting portions W1 and W2 will bend and fall off from the openings K40 and K50 as in the case of Patent Document 1.

また、連結部Ｗ１、Ｗ２は、仮想角部Ｒ１、Ｒ２から突出しておらず、さらには、連結部Ｗ１、Ｗ２は、外箱部Ｂの外周面から突出していないので、連結部Ｗ１、Ｗ２が邪魔になることがない。つまり、特許文献１の包装箱では、突起の脱落を防止するために突起の基端から先端までの長さを長くすると、突起がカバーの端壁から突出してしまい、突起が邪魔になってしまうが、本実施例では、連結部Ｗ１、Ｗ２が邪魔になることがない。 Further, since the connecting portions W1 and W2 do not protrude from the virtual corner portions R1 and R2, and the connecting portions W1 and W2 do not protrude from the outer peripheral surface of the outer box portion B, the connecting portions W1 and W2 do not protrude. It doesn't get in the way. That is, in the packaging box of Patent Document 1, if the length from the base end to the tip of the protrusion is increased in order to prevent the protrusion from falling off, the protrusion protrudes from the end wall of the cover, and the protrusion becomes an obstacle. However, in this embodiment, the connecting portions W1 and W2 do not get in the way.

なお、上記の説明において、切目線１１６Ｋａは、正面部１１０の下辺と、側面部１２０側の上側の角部との間に設けられているとしたが、切目線１１６Ｋａは、側面部１２０側の上側の角部との間に設けられていなくても、正面部１１０の側面部１２０側の辺部に沿った領域（折れ線Ｃ１２−１に沿った領域）で開口部Ｋ４０よりも上側の領域（つまり、図１８のＶ１に示す領域であり、連結部Ｌ４０ａにおける折れ線Ｃ１２−１よりも正面部１１０側の領域）との間に形成されたものであればよく、これにより、切目線１１６Ｋａを破断して、右正面部１１２ａを側面部１２０に対して正面側に回動させることにより、連結部Ｗ１が開口部Ｋ４０に入り込んだ状態を解除させることができる。つまり、切目線１１６Ｋａは、正面部１１０の下辺から開口部Ｋ４０の上側の領域（つまり、正面部１１０の側面部１２０側の辺部に沿った領域で開口部Ｋ４０よりも上側の領域）に向けて形成されていればよく、つまり、切目線１１６Ｋａは、正面部１１０の下辺と、正面部１１０の側面部１２０側の辺部に沿った領域で開口部Ｋ４０よりも上側の領域との間に設けられていればよい。 In the above description, the cut line 116Ka is provided between the lower side of the front surface portion 110 and the upper corner portion on the side surface portion 120 side, but the cut line 116Ka is provided on the side surface portion 120 side. Even if it is not provided between the upper corner, the area along the side surface 120 side of the front surface 110 (the area along the polygonal line C12-1) is the area above the opening K40 (the area above the opening K40). That is, it may be a region shown in V1 of FIG. 18 and may be formed between the region and the region on the front portion 110 side of the polygonal line C12-1 in the connecting portion L40a), thereby breaking the cut line 116Ka. Then, by rotating the right front portion 112a toward the front side with respect to the side surface portion 120, the state in which the connecting portion W1 has entered the opening K40 can be released. That is, the cut line 116Ka is directed from the lower side of the front portion 110 toward the region above the opening K40 (that is, the region along the side portion of the front portion 110 on the side surface portion 120 side and above the opening K40). That is, the cut line 116Ka may be formed between the lower side of the front portion 110 and the region along the side portion of the front portion 110 on the side surface portion 120 side and above the opening K40. It suffices if it is provided.

また、切目線１１６Ｋｂは、正面部１１０の下辺と、側面部１３０側の上側の角部との間に設けられているとしたが、切目線１１６Ｋｂは、側面部１３０側の上側の角部との間に設けられていなくても、正面部１１０における側面部１３０側の辺部に沿った領域（つまり、正面部１１０における折れ線Ｃ１１に沿った領域）との間に形成されていればよい。つまり、切目線１１６Ｋｂが側面部１３０側の上側の角部との間に設けられていなくても、連結部Ｗ１、Ｗ２が開口部Ｋ４０、Ｋ５０に入り込んだ状態を解除した後に、外箱部Ｂを上方に持ち上げればよいので、切目線１１６Ｋｂは、正面部１１０における側面部１３０側の辺部に沿った領域に向けて形成されていればよく、つまり、切目線１１６Ｋｂは、正面部１１０の下辺と、正面部１１０における側面部１３０側の辺部に沿った領域との間に設けられていればよい。 Further, it is said that the cut line 116Kb is provided between the lower side of the front surface portion 110 and the upper corner portion on the side surface portion 130 side, but the cut line 116Kb is provided on the upper corner portion on the side surface portion 130 side. Even if it is not provided between the two, it may be formed between the region along the side portion of the front portion 110 on the side surface portion 130 side (that is, the region along the polygonal line C11 in the front portion 110). That is, even if the cut line 116Kb is not provided between the upper corner portion on the side surface portion 130 side, the outer box portion B is released after the connecting portions W1 and W2 have entered the openings K40 and K50. The cut line 116Kb may be formed toward the region along the side portion of the front portion 110 on the side surface portion 130 side, that is, the cut line 116Kb may be formed on the front portion 110. It may be provided between the lower side and the area along the side portion of the front portion 110 on the side surface portion 130 side.

同様に、切目線１４６Ｋａは、背面部１４０の下辺と、側面部１２０側の上側の角部との間に設けられているとしたが、切目線１４６Ｋａは、側面部１２０側の上側の角部との間に設けられていなくても、背面部１４０の側面部１２０側の辺部に沿った領域（折れ線Ｃ１３−１に沿った領域）で開口部Ｋ５０よりも上側の領域（つまり、図１９のＶ２に示す領域であり、連結部Ｌ５０ａにおける折れ線Ｃ１３−１よりも背面部１４０側の領域）との間に形成されたものであればよく、これにより、切目線１４６Ｋａを破断して、右背面部１４２ａを側面部１２０に対して背面側に回動させることにより、連結部Ｗ２が開口部Ｋ５０に入り込んだ状態を解除させることができる。つまり、切目線１４６Ｋａは、背面部１４０の下辺から開口部Ｋ５０の上側の領域（つまり、背面部１４０の側面部１２０側の辺部に沿った領域で開口部Ｋ５０よりも上側の領域）に向けて形成されていればよく、つまり、切目線１４６Ｋａは、背面部１４０の下辺と、背面部１４０の側面部１２０側の辺部に沿った領域で開口部Ｋ５０よりも上側の領域との間に設けられていればよい。 Similarly, it is said that the cut line 146Ka is provided between the lower side of the back surface portion 140 and the upper corner portion on the side surface portion 120 side, but the cut line 146Ka is provided on the upper corner portion on the side surface portion 120 side. Even if it is not provided between the two, the region along the side portion 120 side of the back surface portion 140 (the region along the polygonal line C13-1) and the region above the opening K50 (that is, FIG. 19). It may be a region shown in V2 of the above, and may be formed between the region and the region on the back surface 140 side of the polygonal line C13-1 in the connecting portion L50a. By rotating the back surface portion 142a to the back surface side with respect to the side surface portion 120, the state in which the connecting portion W2 has entered the opening portion K50 can be released. That is, the cut line 146Ka is directed from the lower side of the back surface portion 140 toward the region above the opening K50 (that is, the region along the side portion of the back surface portion 140 on the side surface portion 120 side and above the opening portion K50). That is, the cut line 146Ka may be formed between the lower side of the back surface portion 140 and the region along the side portion of the back surface portion 140 on the side surface portion 120 side and above the opening K50. It suffices if it is provided.

また、切目線１４６Ｋｂは、背面部１４０の下辺と、側面部１３０側の上側の角部との間に設けられているとしたが、切目線１４６Ｋｂは、側面部１３０側の上側の角部との間に設けられていなくても、背面部１４０における側面部１３０側の辺部に沿った領域（つまり、背面部１４０における折れ線Ｃ１４に沿った領域）との間に形成されていればよい。つまり、切目線１４６Ｋｂが側面部１３０側の上側の角部との間に設けられていなくても、連結部Ｗ１、Ｗ２が開口部Ｋ４０、Ｋ５０に入り込んだ状態を解除した後に、外箱部Ｂを上方に持ち上げればよいので、切目線１４６Ｋｂは、背面部１４０における側面部１３０側の辺部に沿った領域に向けて形成されていればよく、つまり、切目線１４６Ｋｂは、背面部１４０の下辺と、背面部１４０における側面部１３０側の辺部に沿った領域との間に設けられていればよい。 Further, it is said that the cut line 146Kb is provided between the lower side of the back surface portion 140 and the upper corner portion on the side surface portion 130 side, but the cut line 146Kb is provided with the upper corner portion on the side surface portion 130 side. Even if it is not provided between the two, it may be formed between the region along the side portion of the back surface portion 140 on the side surface portion 130 side (that is, the region along the polygonal line C14 of the back surface portion 140). That is, even if the cut line 146Kb is not provided between the upper corner portion on the side surface portion 130 side, the outer box portion B is released after the connecting portions W1 and W2 have entered the openings K40 and K50. The cut line 146Kb may be formed toward the region along the side portion of the back surface portion 140 on the side surface portion 130 side, that is, the cut line 146Kb may be formed on the back surface portion 140. It may be provided between the lower side and the area along the side portion of the back surface portion 140 on the side surface portion 130 side.

また、上記の説明においては、内箱部Ａにおいては、正面部１０と側面部２０の境界位置に切欠部Ｋ１０、Ｋ１２が設けられており、背面部４０と側面部２０の境界位置に切欠部Ｋ２０、Ｋ２２が設けられているとしたが、図３０に示すように、切欠部Ｋ１０、Ｋ２０の構成を省略して、切欠部Ｋ１２、Ｋ２２のみとしてもよい。すなわち、正面部１０と側面部２０の境界位置には、該境界位置の下側から形成された切欠部Ｋ１２のみとし、背面部４０と側面部２０の境界位置には、該境界位置の下側から形成された切欠部２２のみとしてもよい。この場合には、切欠部Ｋ１２よりも上側の領域が連結部Ｗ１となり、切欠部Ｋ２２よりも上側の領域が連結部Ｗ２となる。 Further, in the above description, in the inner box portion A, the cutout portions K10 and K12 are provided at the boundary position between the front surface portion 10 and the side surface portion 20, and the cutout portion is provided at the boundary position between the back surface portion 40 and the side surface portion 20. Although it is assumed that K20 and K22 are provided, as shown in FIG. 30, the configuration of the cutout portions K10 and K20 may be omitted and only the cutout portions K12 and K22 may be provided. That is, at the boundary position between the front surface portion 10 and the side surface portion 20, only the notch K12 formed from the lower side of the boundary position is used, and at the boundary position between the back surface portion 40 and the side surface portion 20, the lower side of the boundary position is used. It may be only the notch 22 formed from. In this case, the region above the notch K12 is the connecting portion W1, and the region above the notch K22 is the connecting portion W2.

すなわち、図３０に示す内箱部Ａと図３１に示す外箱部Ｂからなる包装箱のように、外箱部Ｂのスリーブ状部１０５の上下方向の長さが内箱部Ａのスリーブ状部５の上下方向の長さよりも十分長い場合には（つまり、スリーブ状部５の上辺の高さがスリーブ状部１０５の上辺の高さよりも十分下側にある）、切欠部Ｋ１０、Ｋ２０の構成が省略されても、連結部Ｗ１が開口部Ｋ４０内に入り込むことができ、連結部Ｗ２が開口部Ｋ５０内に入り込んだ状態とすることができる。 That is, like the packaging box composed of the inner box portion A shown in FIG. 30 and the outer box portion B shown in FIG. 31, the length of the sleeve-shaped portion 105 of the outer box portion B in the vertical direction is the sleeve shape of the inner box portion A. If it is sufficiently longer than the vertical length of the portion 5 (that is, the height of the upper side of the sleeve-shaped portion 5 is sufficiently lower than the height of the upper side of the sleeve-shaped portion 105), the cutout portions K10 and K20 Even if the configuration is omitted, the connecting portion W1 can enter the opening K40, and the connecting portion W2 can enter the opening K50.

なお、上記の説明においては、正面部１０に一対の切目線（切目線１６Ｋａ、１６Ｋｂ）を設けるとともに背面部４０に一対の切目線（切目線４６Ｋａ、４６Ｋｂ）を設け、正面部１１０に一対の切目線（切目線１１６Ｋａ、１１６Ｋｂ）を設けるとともに背面部１４０に一対の切目線（切目線１４６Ｋａ、１４６Ｋｂ）を設け、正面部１０と側面部２０の境界位置に一対の切欠部（切欠部Ｋ１０、Ｋ１２）を設けるとともに、背面部４０と側面部２０の境界位置に一対の切欠部（切欠部Ｋ２０、Ｋ２２）を設け、正面部１１０と側面部１２０の境界位置に開口部Ｋ４０を設けるとともに、背面部１４０と側面部１２０の境界位置に開口部Ｋ５０を設けるとしたが、側面部２０と側面部３０に一対の切目線を設ける（つまり、側面部２０に切目線１６Ｋａ、１６Ｋｂを設け、側面部３０に切目線４６Ｋａ、４６Ｋｂを設ける）とともに、側面部１２０と側面部１３０に一対の切目線を設け（つまり、側面部１２０に切目線１１６Ｋａ、１１６Ｋｂを設け、側面部１３０に切目線１４６Ｋａ、１４６Ｋｂを設ける）、側面部２０と正面部１０の境界位置に一対の切欠部（つまり、切欠部Ｋ１０、Ｋ１２）を設けるとともに、側面部３０と正面部１０の境界位置に一対の切欠部（つまり、切欠部Ｋ２０、Ｋ２２）を設け、側面部１２０と正面部１１０の境界位置に開口部（つまり、開口部Ｋ４０）を設けるとともに、側面部１３０と正面部１１０の境界位置に開口部（つまり、開口部Ｋ５０）を設ける構成としてもよい。
その場合には、側面部２０が第１対象内側側面部となり、側面部３０が第２対象内側側面部となり、正面部１０が第１隣接内側側面部となり、背面部４０が第２隣接内側側面部となり、側面部１２０が第１対象外側側面部となり、側面部１３０が第２対象外側側面部となり、正面部１１０が第１隣接外側側面部となり、背面部１４０が第２隣接外側側面部となり、側面部２０と側面部１２０が接着されるとともに、側面部３０と側面部１３０が接着された構成となる。 In the above description, a pair of cut lines (cut lines 16Ka, 16Kb) are provided on the front portion 10, a pair of cut lines (cut lines 46Ka, 46Kb) are provided on the back portion 40, and a pair of cut lines (cut lines 46Ka, 46Kb) are provided on the front portion 110.
