Description

本発明は、内容物を収納する包装箱に関する。   The present invention relates to a packaging box for storing contents.

従来の包装箱は特許文献１に開示されている。この包装箱は直方体形状を有し、筒状の胴部、天面板、第１底面板、第２底面板及び接着片を備える。筒状の胴部は折り線を介して交互に配される第１側面板及び第２側面板をそれぞれ２枚有する。   A conventional packaging box is disclosed in Patent Document 1. The packaging box has a rectangular parallelepiped shape, and includes a cylindrical body, a top plate, a first bottom plate, a second bottom plate, and an adhesive piece. The cylindrical body portion has two first side plates and two second side plates arranged alternately via folding lines.

天面板は後端に設けた折り線によって一方の第１側面板に対して折曲可能に形成される。天面板の先端部は折り線により折曲される。天面板の先端部を他方の第１側面板の上端部の内側に差し込むことにより、天面板は胴部の上面を閉じる。   The top plate is formed to be bendable with respect to one first side plate by a fold line provided at the rear end. The tip of the top plate is bent along the fold line. The top plate closes the top surface of the body portion by inserting the tip of the top plate into the inside of the upper end of the other first side plate.

第１底面板及び第２底面板はそれぞれ第１側面板及び第２側面板の下方に折り線を介して連設される。接着片は第１底面板に対して折り線から成る折畳み部を介して連設されるとともに所定の接着領域で第２底面板が接着片の内面側に接着される。胴部の内部に向かって山折りされる折畳み部を折り戻し、一対の第１底面板が互いに係合して包装箱の底面が形成される。これにより、胴部の下面が閉じられる。   The first bottom plate and the second bottom plate are connected to each other below the first side plate and the second side plate via a fold line, respectively. The adhesive piece is connected to the first bottom plate via a fold line formed of a fold line, and the second bottom plate is bonded to the inner surface side of the adhesive piece in a predetermined bonding region. The folded portion that is folded inward toward the inside of the body portion is folded back, and the pair of first bottom surface plates engage with each other to form the bottom surface of the packaging box. Thereby, the lower surface of the trunk is closed.

また、接着片は接着領域を囲む囲み部を有する。囲み部は切込みから成る複数の切込み部をそれぞれ非切込み部により連結して接着領域を囲む。囲み部は平面形状が矩形に形成され、折畳み部に対して一辺が傾斜する。囲み部の各コーナーには切込み部が配され、一のコーナーが折畳み部に面して配される。   The adhesive piece has a surrounding portion surrounding the adhesive region. The enclosing portion surrounds the adhesive region by connecting a plurality of incisions made of incisions with non-incisions. The surrounding part is formed in a rectangular planar shape, and one side is inclined with respect to the folded part. A cut portion is arranged at each corner of the enclosing portion, and one corner is arranged facing the folding portion.

上記構成の包装箱は使用場所に搬送される際には、天面板を開いて一方の第１側面板と一方の第２側面板との間の折り線及び他方の第１側面板と他方の第２側面板との間の折り線で胴部が折り曲げられて扁平に押し潰された状態になっている。この時、一対の第１底面板の係合は解除され、折畳み部は胴部の内部に向かって山折りされる。これにより、第１底面板上に接着片及び第２底面板が重なって配され、胴部の下面が開放される。   When the packaging box having the above structure is transported to the place of use, the top plate is opened, the folding line between one first side plate and one second side plate, and the other first side plate and the other side plate. The trunk portion is bent at the folding line between the second side plate and flattened. At this time, the engagement between the pair of first bottom plates is released, and the folding portion is folded inward toward the inside of the trunk portion. As a result, the adhesive piece and the second bottom surface plate are arranged on the first bottom surface plate, and the lower surface of the body portion is opened.

扁平に押し潰された胴部に対して、一方の第１側面板と一方の第２側面板との間の折り線及び他方の第１側面板と他方の第２側面板との間の折り線を手指で押さえ、一方の折り線を他方の折り線に向かって押す。これにより、第２側面板が第１側面板に対して略垂直になるように胴部が起こされて筒状の胴部が形成される。   Folding line between one first side plate and one second side plate and folding between the other first side plate and the other second side plate with respect to the body portion crushed flatly Hold the line with your fingers and push one fold line toward the other fold line. As a result, the barrel is raised so that the second side plate is substantially perpendicular to the first side plate to form a cylindrical barrel.

この時、胴部の内部に向かって山折りされた折畳み部が折り戻され、一対の第１底面板が互いに係合して包装箱の底面が形成される。すなわち、包装箱の底面はいわゆるオートボトム構造を有する。これにより、内容物を収納する場所において包装箱を容易に組み立てることができる。   At this time, the folded portion folded in the mountain toward the inside of the body portion is folded back, and the pair of first bottom surface plates engage with each other to form the bottom surface of the packaging box. That is, the bottom surface of the packaging box has a so-called auto bottom structure. Thereby, a packaging box can be easily assembled in the place which stores the contents.

内容物が収納された包装箱において、接着片の先端部を摘持して第２底面板から接着片を剥がすと、囲み部の非切込み部に対して一端から他端に向かう力が加わって非切込み部が破断する。このため、開封された痕跡が包装箱の底面に残る。したがって、包装箱に収納された内容物の改竄を防止することができる。   In the packaging box containing the contents, if the adhesive piece is peeled off from the second bottom plate by grasping the tip of the adhesive piece, a force from one end to the other end is applied to the non-cut portion of the enclosing portion. Non-incision breaks. For this reason, the opened trace remains on the bottom surface of the packaging box. Therefore, falsification of the contents stored in the packaging box can be prevented.

特開２００７−４５４４７号公報（第３頁、第４頁、第１図、第３図）JP 2007-45447 A (3rd page, 4th page, FIG. 1, FIG. 3)

しかしながら、上記従来の包装箱によると、包装箱を組み立てて底面を形成する際に、第１底面板は折畳み部の折り戻しに伴って下方に向けて力が加わる。接着片は接着領域で第２底面板に接着されるため、接着片には囲み部と折畳み部との間が囲み部内に対して離れる方向の力が作用する。この時、折畳み部に対向する囲み部のコーナーに切込み部が配されるため、接着片が該切込み部で分離して該切込み部に隣接した非切込み部が破断する場合がある。したがって、包装箱に内容物が収納される商品の歩留りが低下する問題があった。   However, according to the above-described conventional packaging box, when the packaging box is assembled to form the bottom surface, the first bottom plate is subjected to a force downward as the folding portion is folded back. Since the adhesive piece is bonded to the second bottom plate in the adhesive region, a force in a direction in which the space between the enclosing portion and the folding portion is separated from the inside of the enclosing portion acts on the adhesive piece. At this time, since the cut portion is arranged at the corner of the enclosing portion facing the folding portion, the adhesive piece may be separated at the cut portion, and the non-cut portion adjacent to the cut portion may break. Therefore, there has been a problem that the yield of products whose contents are stored in the packaging box is lowered.

本発明は、組み立て性を低下させずに箱に内容物が収納される商品の歩留りを向上できる包装箱を提供することを目的とする。   An object of this invention is to provide the packaging box which can improve the yield of the goods by which the contents are accommodated in a box, without reducing an assembly property.

上記目的を達成するために本発明は、折り線を介して交互に配される第１側面板及び第２側面板をそれぞれ複数有した筒状の胴部と、前記胴部の上面を閉じる天面板と、第１側面板の下方に折り線を介して連設される第１底面板と、第２側面板の下方に折り線を介して連設される第２底面板と、第１底面板に対して折り線から成る折畳み部を介して連設されるとともに所定の接着領域で第２底面板が内面側に接着される接着片とを備え、前記胴部の内部に向かって山折りされる前記折畳み部を折り戻し、複数の第１底面板が互いに係合して底面を形成する包装箱において、前記接着片が切込みから成る複数の第１切込み部をそれぞれ非切込み部により連結して前記接着領域を囲む囲み部を有し、一の前記非切込み部により前記折畳み部に近接して対向する対向部を形成し、前記対向部の長さが前記対向部を除く前記非切込み部よりも長いことを特徴としている。   In order to achieve the above object, the present invention provides a cylindrical body having a plurality of first side plates and a plurality of second side plates arranged alternately via folding lines, and a ceiling for closing the upper surface of the body.

Then, when the contents are put into a cylindrical body and the upper surface is closed with a top plate, the contents are stored in the packaging box. When the tip of the adhesive piece is held and the adhesive piece is peeled off from the second bottom plate, the non-cut portion is broken.

また本発明は、上記構成の包装箱において、前記囲み部の平面形状を前記折畳み部に対して一辺を傾斜した略矩形に形成するとともに、前記囲み部の一頂部に前記対向部を配置するとともに前記対向部の対角位置の頂部に第１切込み部を配置すると好ましい。   According to the present invention, in the packaging box having the above-described configuration, the planar shape of the surrounding portion is formed into a substantially rectangular shape with one side inclined with respect to the folding portion, and the facing portion is disposed at the top of the surrounding portion. It is preferable to arrange the first cut portion at the top of the opposing portion at the diagonal position.

以下に本発明の実施形態を図面を参照して説明する。図１及び図２は本発明の一実施形態の包装箱の斜視図を示している。図１は開封前の包装箱１を示し、図２は天面板７を閉じる前の包装箱１を示している。包装箱１は直方体形状を有し、筒状の胴部１０、天面板７及び底面部６（図３参照）を備えて内容物（不図示）を収納する。胴部１０は上端及び下端にそれぞれ開口面（不図示）を有する。天面板７は上方の開口面を閉じ、底面部６は下方の開口面を閉じる。   Embodiments of the present invention will be described below with reference to the drawings. FIG.1 and FIG.2 has shown the perspective view of the packaging box of one Embodiment of this invention. FIG. 1 shows the packaging box 1 before opening, and FIG. 2 shows the packaging box 1 before the top plate 7 is closed. The packaging box 1 has a rectangular parallelepiped shape, and includes a cylindrical body portion 10, a top plate 7, and a bottom surface portion 6 (see FIG. 3) and stores contents (not shown). The trunk | drum 10 has an opening surface (not shown) at an upper end and a lower end, respectively. The top plate 7 closes the upper opening surface, and the bottom surface portion 6 closes the lower opening surface.

胴部１０は水平方向に順に連設される４枚の側面板２、側面板３、側面板４（図４参照）、側面板５（図４参照）により軸方向（上下方向）に垂直な断面が矩形に形成される。側面板３、５（第１側面板）が互いに対向し、側面板２、４（第２側面板）が互いに対向する。また、側面板２と側面板３との間及び側面板４と側面板５との間には、胴部１０の軸方向（上下方向）に延びる折り線９０から成る折曲部９３、９４（折曲部９４については図４及び図５参照）がそれぞれ設けられる。   The body portion 10 is perpendicular to the axial direction (vertical direction) by four side plates 2, a side plate 3, a side plate 4 (see FIG. 4), and a side plate 5 (see FIG. 4) that are sequentially arranged in the horizontal direction. The cross section is formed in a rectangular shape. The side plates 3 and 5 (first side plate) face each other, and the side plates 2 and 4 (second side plate) face each other. In addition, between the side plate 2 and the side plate 3 and between the side plate 4 and the side plate 5, bent portions 93 and 94 (folding lines 90 extending in the axial direction (vertical direction) of the trunk portion 10) are provided. As for the bent portion 94, see FIG. 4 and FIG.

側面板３の上端には折り線９０を介して前方フラップ３１が連設される。また、側面板３と前方フラップ３１との間の折り線９０上にはスリット３ａ（第３切込み部）が設けられる。すなわち、前方フラップ３１はスリット３ａの両端に一直線上に配した折り線９０を介して側面板３の上端に連設される。スリット３ａは両端部で側面板３上に延びて互いに広がる方向に傾斜するとともに所定位置で内側に屈曲する。   A front flap 31 is connected to the upper end of the side plate 3 via a fold line 90. In addition, a slit 3 a (third cut portion) is provided on the fold line 90 between the side plate 3 and the front flap 31. That is, the front flap 31 is connected to the upper end of the side plate 3 via the fold line 90 arranged in a straight line at both ends of the slit 3a. The slits 3a extend on the side plate 3 at both ends and incline in a direction in which the slits 3a spread with each other and bend inward at a predetermined position.

天面板７は後端に設けた折り線９０によって側面板５に対して折曲可能に形成され、帯状部７１及び挿入部７２を有する。挿入部７２は天面板７の先端部を折り線９０により折曲してスリット３ａに挿入される。また、挿入部７２は基部７２ｂから両側方に突出して形成される係止部７２ａを有する。これにより、スリット３ａに挿入された挿入部７２を上方に向けて引くと、係止部７２ａがスリット３ａの下端に係止される。したがって、スリット３ａに挿入された挿入部７２がスリット３ａから抜けることを防止できる。   The top plate 7 is formed to be bendable with respect to the side plate 5 by a fold line 90 provided at the rear end, and has a belt-like portion 71 and an insertion portion 72. The insertion portion 72 is inserted into the slit 3a by bending the tip portion of the top plate 7 along the fold line 90. Moreover, the insertion part 72 has the latching | locking part 72a formed protruding from the base 72b to both sides. Thereby, when the insertion part 72 inserted in the slit 3a is pulled upward, the locking part 72a is locked to the lower end of the slit 3a. Therefore, it can prevent that the insertion part 72 inserted in the slit 3a slips out of the slit 3a.

なお、スリット３ａが両端部で側面板３上に延びて互いに広がる方向に傾斜するとともに所定位置で外側に屈曲してもよい。この場合でも、スリット３ａに挿入された挿入部７２を上方に向けて引いても係止部７２ａがスリット３ａの下端に係止され、スリット３ａから抜くことができない。   In addition, the slit 3a may extend on the side plate 3 at both ends and incline in a direction in which the slit 3a spreads, and may be bent outward at a predetermined position. Even in this case, even if the insertion portion 72 inserted into the slit 3a is pulled upward, the locking portion 72a is locked to the lower end of the slit 3a and cannot be removed from the slit 3a.

帯状部７１はミシン目状の対向する一対の切断部７１ａにより天面板７から切り取り可能に形成される。切断部７１ａは天面板７の前部に左右方向に延びて前後に対向する。前方の切断部７１ａは天面板７の挿入部７２を折曲する折り線９０上に設けられ、スリット３ａ上に配される。また、後方の切断部７１ａは天面板７の両側端に渡って延びている。後方の切断部７１ａの左端にはＶ字状の切れ目から成るノッチ部７１ｂが形成される。使用者が帯状部７１の左端部を摘持して右方へ引くと、切断部７１ａに沿って帯状部７１が天面板７から切り取られる。これにより、使用者は包装箱１を容易に開封することができる。   The belt-like portion 71 is formed so as to be cut off from the top plate 7 by a pair of opposing cut portions 71a having a perforation shape. The cutting part 71a extends in the left-right direction at the front part of the top plate 7 and faces the front and rear. The front cutting part 71a is provided on a folding line 90 that bends the insertion part 72 of the top plate 7, and is arranged on the slit 3a. Further, the rear cutting portion 71 a extends over both side ends of the top plate 7. A notch portion 71b made of a V-shaped cut is formed at the left end of the rear cut portion 71a. When the user grips the left end portion of the strip portion 71 and pulls it to the right, the strip portion 71 is cut from the top plate 7 along the cutting portion 71a. Thereby, the user can open the packaging box 1 easily.

図３は包装箱１の底面図を示している。包装箱１の底面部６は一対の第１底面板６３、６５、一対の接着片６３ａ、６５ａ及び一対の第２底面板６２、６４を有する。第１底面板６３、６５は折り線９０を介してそれぞれ側面板３及び側面板５の下端に連設される。接着片６３ａ、６５ａは側面板３に対して傾斜した折り線９０から成る折畳み部９２を介してそれぞれ第１底面板６３、６５の側端に連設される。第２底面板６２、６４は折り線９０を介してそれぞれ側面板２、４の下端に連設される。第２底面板６２、６４は接着領域Ｂ２、Ａ２（図４参照）を介して接着剤等によりそれぞれ接着片６３ａ、６５ａの内面の接着領域Ｂ１、Ａ１（図４参照）に接着される。   FIG. 3 shows a bottom view of the packaging box 1. The bottom surface portion 6 of the packaging box 1 includes a pair of first bottom surface plates 63 and 65, a pair of adhesive pieces 63a and 65a, and a pair of second bottom surface plates 62 and 64. The first bottom plates 63 and 65 are connected to the lower ends of the side plate 3 and the side plate 5 through folding lines 90, respectively. The adhesive pieces 63a and 65a are connected to the side ends of the first bottom surface plates 63 and 65, respectively, via a folding portion 92 formed of a folding line 90 inclined with respect to the side surface plate 3. The second bottom plates 62 and 64 are connected to the lower ends of the side plates 2 and 4 via the folding line 90, respectively. The second bottom plates 62 and 64 are bonded to the bonding regions B1 and A1 (see FIG. 4) on the inner surfaces of the bonding pieces 63a and 65a by adhesives and the like through the bonding regions B2 and A2 (see FIG. 4), respectively.

第１底面板６３の先端部が接着片６５ａに接着された第２底面板６４の内面側に配されるとともに、第１底面板６５の先端部が接着片６３ａに接着された第２底面板６２の内面側に配される。この時、第１底面板６３、６５が互いに係合して底面部６が形成される。なお、底面部６の形成方法の詳細は後述する。   A second bottom surface plate in which the front end portion of the first bottom surface plate 63 is disposed on the inner surface side of the second bottom surface plate 64 adhered to the adhesive piece 65a, and the front end portion of the first bottom surface plate 65 is adhered to the adhesive piece 63a. 62 is disposed on the inner surface side. At this time, the first bottom surface plates 63 and 65 are engaged with each other to form the bottom surface portion 6. Details of the method of forming the bottom surface portion 6 will be described later.

接着片６３ａ、６５ａには囲み部８０が設けられる。囲み部８０は切込みから成る複数の切込み部８１（第１切込み部）をそれぞれ非切込み部８２により連結して接着領域Ａ１、Ｂ１（図４参照）を囲む。囲み部８０は平面形状を折畳み部９２に対して一辺を傾斜した略矩形に形成される。詳細を後述するように、非切込み部８２が破断している場合に底面部６を介して内容物の改竄が行われたと判断することができる。   A surrounding portion 80 is provided in the adhesive pieces 63a and 65a. The enclosing portion 80 surrounds the adhesive regions A1 and B1 (see FIG. 4) by connecting a plurality of incising portions 81 (first incising portions) made of incisions by non-incising portions 82, respectively. The surrounding portion 80 is formed in a substantially rectangular shape having a planar shape inclined on one side with respect to the folding portion 92. As will be described in detail later, it can be determined that the content has been tampered via the bottom surface portion 6 when the non-cut portion 82 is broken.

また、一の非切込み部８２により折畳み部９２に近接して対向する対向部８２ａを形成する。対向部８２ａの長さは対向部８２ａを除く非切込み部８２よりも長くなっている。対向部８２ａは囲み部８０の一頂部に配置されるとともに対向部８２ａの対角位置の頂部に切込み部８１が配置される。   Moreover, the opposing part 82a which adjoins and closes the folding part 92 by the one non-cut part 82 is formed. The length of the facing portion 82a is longer than that of the non-cut portion 82 excluding the facing portion 82a. The facing portion 82a is disposed at the top of the surrounding portion 80, and the cut portion 81 is disposed at the top of the diagonal position of the facing portion 82a.

また、囲み部８０は非切込み部８２に対向した切込みから成る切込み部８３（第２切込み部）を有する。切込み部８３は非切込み部８２に近接して切込み部８１よりも囲み部８０の内側に設けられる。なお、切込み部８３を切込み部８１よりも囲み部８０の外側に設けてもよい。また、対向部８２ａに近接して対向する位置には切込み部８３を設けない。   The surrounding portion 80 has a cut portion 83 (second cut portion) formed by a cut facing the non-cut portion 82. The cut portion 83 is provided closer to the non-cut portion 82 and inside the surrounding portion 80 than the cut portion 81. Note that the cut portion 83 may be provided outside the enclosing portion 80 with respect to the cut portion 81. Moreover, the notch part 83 is not provided in the position which opposes near the opposing part 82a.

囲み部８０内にはミシン目状の接着剤保持部１１が設けられる。接着剤保持部１１のミシン目で接着剤が保持されやすくなり、接着片６３ａ、６５ａをそれぞれ第２底面板６２、６４に確実に接着させることができる。   A perforated adhesive holder 11 is provided in the enclosure 80. The adhesive is easily held by the perforation of the adhesive holding part 11, and the adhesive pieces 63 a and 65 a can be securely bonded to the second bottom surface plates 62 and 64, respectively.

図４は包装箱１の展開図を示している。なお、図４は組立後の包装箱１の外面になる部分を見た図になっている。包装箱１を形成するブランク板１００は紙製のシートを打ち抜いて形成される。ブランク板１００の材質に特に限定はないが、例えばマニラボール、ボール紙、カード紙、クラフトボール等の板紙を用いることができる。また、樹脂シートによりブランク板１００を形成してもよい。   FIG. 4 shows a development view of the packaging box 1. FIG. 4 is a view of a portion that becomes the outer surface of the packaging box 1 after assembly. The blank plate 100 forming the packaging box 1 is formed by punching a paper sheet. The material of the blank board 100 is not particularly limited, and for example, paperboard such as Manila ball, cardboard, card paper, craft ball, or the like can be used. Moreover, you may form the blank board 100 with a resin sheet.

側面板２、３、４、５は折り線９０を介して順に連設され、側面板５の一端には糊代片５５が折り線を介して連設される。糊代片５５を側面板２の内面に接着して胴部１０（図１参照）が形成される。側面板３の上端には折り線９０を介して前方フラップ３１（フラップ）が連設され、側面板５の上端には折り線９０を介して天面板７が連設される。側面板３、５の下端には折り線９０を介してそれぞれ第１底面板６３、６５が連設される。   The side plates 2, 3, 4, and 5 are sequentially connected via a fold line 90, and an adhesive margin piece 55 is connected to one end of the side plate 5 via a fold line. The glue piece 55 is bonded to the inner surface of the side plate 2 to form the body portion 10 (see FIG. 1). A front flap 31 (flap) is connected to the upper end of the side plate 3 via a fold line 90, and the top plate 7 is connected to the upper end of the side plate 5 via a fold line 90. First bottom plates 63 and 65 are connected to lower ends of the side plates 3 and 5 via folding lines 90, respectively.

側面板２、４の上端には折り線９０を介してそれぞれ側方フラップ２１、４１が連設され、下端には折り線９０を介してそれぞれ第２底面板６２、６４が連設される。第２底面板６２、６４の外面の一部には接着領域Ｂ２、Ａ２が形成され、接着領域Ｂ２、Ａ２上にはミシン目状の接着剤保持部１１が設けられる。   Side flaps 21 and 41 are connected to the upper ends of the side plates 2 and 4 via folding lines 90, respectively, and second bottom plates 62 and 64 are connected to the lower ends via the folding lines 90, respectively. Adhesive regions B2 and A2 are formed on a part of the outer surfaces of the second bottom plates 62 and 64, and a perforated adhesive holder 11 is provided on the adhesive regions B2 and A2.

第１底面板６３、６５及び第２底面板６２、６４の図中、右方に面した側辺は側面板３の底辺に対して略４５゜傾斜している。接着片６３ａ、６５ａは第１底面板６３、６５の傾斜した右方の側辺を延長した折り線９０から成る折畳み部９２を介して第１底面板６３、６５に連設される。接着片６３ａ、６５ａの内面にはそれぞれ接着領域Ｂ１、Ａ１が形成され、接着領域Ｂ１、Ａ１上にはミシン目状の接着剤保持部１１が設けられる。また、接着片６３ａ、６５ａには接着領域Ｂ１、Ａ１を囲む囲み部８０が設けられる。   In the drawings of the first bottom plate 63, 65 and the second bottom plate 62, 64, the side facing toward the right is inclined by approximately 45 ° with respect to the bottom of the side plate 3. The adhesive pieces 63a and 65a are connected to the first bottom surface plates 63 and 65 via a fold portion 92 formed of a fold line 90 extending from the inclined right side of the first bottom surface plates 63 and 65. Adhesive regions B1 and A1 are formed on the inner surfaces of the adhesive pieces 63a and 65a, respectively, and a perforated adhesive holder 11 is provided on the adhesive regions B1 and A1. Further, the adhesive pieces 63a and 65a are provided with a surrounding portion 80 surrounding the adhesive regions B1 and A1.

図４のブランク板１００において、側面板２、４をそれぞれ折り線９０で側面板３の内面側に向けて略９０度折り曲げる。そして、側面板５を側面板４の内面側に向けて折り線９０で略９０度折り曲げるとともに、糊代片５５を側面板５の内面側に向けて折り線９０で略９０度折り曲げる。   In the blank plate 100 of FIG. 4, the side plates 2, 4 are bent by approximately 90 degrees toward the inner surface side of the side plate 3 along the fold line 90. Then, the side plate 5 is bent approximately 90 degrees along the fold line 90 toward the inner surface side of the side plate 4, and the adhesive margin piece 55 is bent approximately 90 degrees along the fold line 90 toward the inner surface side of the side plate 5.

そして、接着剤等により糊代片５５の外面を側面板２の後端部（図４では右端部）の内面に接着させる。これにより、筒状の胴部１０が形成される。   Then, the outer surface of the adhesive margin piece 55 is adhered to the inner surface of the rear end portion (right end portion in FIG. 4) of the side plate 2 with an adhesive or the like. Thereby, the cylindrical trunk | drum 10 is formed.

また、接着領域Ａ１、Ａ２の少なくとも一方に接着剤等が塗布され、接着領域Ａ１、Ａ２で接着片６５ａと第２底面板６４とが貼り合わされる。接着領域Ｂ１、Ｂ２の少なくとも一方に接着剤等が塗布され、接着領域Ｂ１、Ｂ２で接着片６３ａと第２底面板６２とが貼り合わされる。   Further, an adhesive or the like is applied to at least one of the adhesion areas A1 and A2, and the adhesive piece 65a and the second bottom plate 64 are bonded to each other in the adhesion areas A1 and A2. An adhesive or the like is applied to at least one of the bonding regions B1 and B2, and the adhesive piece 63a and the second bottom plate 62 are bonded to each other in the bonding regions B1 and B2.

そして、側面板２、３間の折り線９０から成る折曲部９３で側面板２、３が対向するように折曲し、側面板４、５間の折り線９０から成る折曲部９４で側面板４、５が対向するように折曲する。これにより、胴部１０を扁平に押し潰すことができる。   Then, the side plates 2 and 3 are bent so that the side plates 2 and 3 face each other at a bent portion 93 formed by a fold line 90 between the side plates 2 and 3, and the bent portion 94 formed by a fold line 90 between the side plates 4 and 5. Bend so that the side plates 4 and 5 face each other. Thereby, the trunk | drum 10 can be crushed flat.

図５は胴部１０が扁平に押し潰された包装箱１を示す正面図である。図６は、胴部１０が扁平に押し潰された包装箱１の底面図である。なお、図６では囲み部８０の図示を省略している。側面板５及び側面板２の内面はそれぞれ側面板４及び側面板３の内面に近接している。この時、第１底面板６５、６３は互いに離れている。すなわち、第１底面板６３、６５の係合が解除されている。また、折畳み部９２は胴部１０の内部に向かって山折りされ、接着片６３ａ、６５ａはそれぞれ第１側面板６３、６５に重なって配される。以上のように、胴部１０が扁平に押し潰された包装箱１では底面部６は胴部１０の下面を閉じていない。   FIG. 5 is a front view showing the packaging box 1 in which the body portion 10 is flattened. FIG. 6 is a bottom view of the packaging box 1 in which the body portion 10 is flattened. In addition, illustration of the enclosure part 80 is abbreviate | omitted in FIG. The inner surfaces of the side plate 5 and the side plate 2 are close to the inner surfaces of the side plate 4 and the side plate 3, respectively. At this time, the first bottom plates 65 and 63 are separated from each other. That is, the engagement of the first bottom plates 63 and 65 is released. Moreover, the folding part 92 is mountain-folded toward the inside of the trunk | drum 10, and the adhesive pieces 63a and 65a are arrange | positioned so that it may overlap with the 1st side plates 63 and 65, respectively. As described above, in the packaging box 1 in which the body portion 10 is flattened, the bottom surface portion 6 does not close the lower surface of the body portion 10.

包装箱１は扁平に押し潰された容積の小さい状態で輸送や保管が行われる。したがって、包装箱１の輸送コスト及び保管コストを削減することができる。   The packaging box 1 is transported and stored in a flat and crushed state with a small volume. Therefore, the transportation cost and storage cost of the packaging box 1 can be reduced.

図５の状態から折曲部９３、９４を互いに接近する方向に手指で押さえる。これにより、側面板２、４が側面板３及び側面板５に対して略垂直になるように胴部１０が起こされる。   From the state of FIG. 5, the bent portions 93 and 94 are pressed with fingers in a direction approaching each other. Thereby, the trunk | drum 10 is raised so that the side plates 2 and 4 may become substantially perpendicular | vertical with respect to the side plate 3 and the side plate 5.

図７及び図８は図５の扁平に押し潰された状態から包装箱１を組み立てる際の底面部６が形成される様子を示す斜視図である。上記のように、折曲部９３を折曲部９４側へ押して胴部１０を起こすと、胴部１０の内部に向かって山折りされた折畳み部９２が折り戻されて、第１底面板６３、６５が互いに係合して底面部６を形成する。この時、第１底面板６５の先端部が第１底面板６３と第２底面板６２との間を通って第２底面板６２の内面側に配される。また、第１底面板６３の先端部が第１底面板６５と第２底面板６４との間を通って第２底面板６４の内面側に配される。   7 and 8 are perspective views showing how the bottom surface portion 6 is formed when the packaging box 1 is assembled from the flattened state of FIG. As described above, when the bent portion 93 is pushed toward the bent portion 94 to raise the barrel portion 10, the folded portion 92 that is mountain-folded toward the inside of the barrel portion 10 is folded back, and the first bottom plate 63. , 65 engage with each other to form the bottom surface portion 6. At this time, the front end portion of the first bottom plate 65 is disposed between the first bottom plate 63 and the second bottom plate 62 on the inner surface side of the second bottom plate 62. Further, the front end portion of the first bottom plate 63 is disposed on the inner surface side of the second bottom plate 64 through between the first bottom plate 65 and the second bottom plate 64.

以上のように、扁平に押し潰された胴部１０を起こすと同時に底面部６も形成される。すなわち、包装箱１はいわゆるオートボトム構造を有する。これにより、内容物を包装箱１に収納する場所で包装箱１を容易に組み立てることができる。   As described above, the bottom surface portion 6 is also formed at the same time as raising the body portion 10 crushed flat. That is, the packaging box 1 has a so-called auto bottom structure. Thereby, the packaging box 1 can be easily assembled at the place where the contents are stored in the packaging box 1.

包装箱１を組み立てて底面部６を形成する際に、第１底面板６３、６５は折畳み部９２の折り戻しに伴って下方に向けて力が加わる。接着片６３ａ、６５ａは接着領域Ｂ１、Ａ１でそれぞれ第２底面板６２、６４に接着されるため、接着片６３ａ、６５ａには囲み部８０と折畳み部９２との間が囲み部８０内に対して離れる方向の力が作用する。   When the packaging box 1 is assembled to form the bottom surface portion 6, the first bottom surface plates 63 and 65 are applied with a downward force as the folding portion 92 is folded back. Since the adhesive pieces 63a and 65a are bonded to the second bottom plates 62 and 64 in the adhesive regions B1 and A1, respectively, the adhesive pieces 63a and 65a have a space between the enclosing portion 80 and the folding portion 92 with respect to the inside of the enclosing portion 80. A force in the direction of separating is applied.

この時、一の非切込み部８２により折畳み部９２に近接して対向する対向部８２ａを形成し、対向部８２ａの長さが対向部８２ａを除く非切込み部８２よりも長くなっている。このため、包装箱１を組み立てる過程で折畳み部９２に力が加わっても対向部８２ａの破断を防止することができる。また、対向部８２ａを除く非切込み部８２は対向部８２ａよりも折畳み部９２から離れているため、折畳み部９２に力が加わっても破断しにくい。したがって、包装箱１の組み立て過程における非切込み部８２の破断を防止することができる。   At this time, the one non-cut portion 82 forms a facing portion 82a facing the folding portion 92 in the vicinity, and the length of the facing portion 82a is longer than the non-cut portion 82 excluding the facing portion 82a. For this reason, even if force is added to the folding part 92 in the process of assembling the packaging box 1, the opposing part 82a can be prevented from being broken. Moreover, since the non-notch | incision part 82 except the opposing part 82a is separated from the folding part 92 rather than the opposing part 82a, even if force is added to the folding part 92, it is hard to fracture | rupture. Therefore, breakage of the non-cut portion 82 in the assembly process of the packaging box 1 can be prevented.

底面部６を形成した胴部１０内には、上方の開口面を介して内容物が収納される。その後に、前方フラップ３１を側面板３の内面側に向けて折り線９０で略９０度折り曲げた後に、側方フラップ２１、４１を前方フラップ３１に向けて折り線９０で略９０度折り曲げる。そして、天面板７を側方フラップ２１、４１に向けて折り線９０で略９０度折り曲げるとともに、挿入部７２を折り線９０で天面板７の内面側に向けて略９０度折り曲げる。その後に、挿入部７２をスリット３ａに挿入する。これにより、天面板７は胴部１０の上方の開口面を閉じ、内容物は包装箱１内に収納される。   The contents are accommodated in the body portion 10 where the bottom surface portion 6 is formed through the upper opening surface. Thereafter, the front flap 31 is bent toward the inner surface side of the side plate 3 by a fold line 90 and then folded about 90 degrees along the fold line 90, and then the side flaps 21 and 41 are folded toward the front flap 31 along the fold line 90. Then, the top plate 7 is bent approximately 90 degrees along the fold line 90 toward the side flaps 21 and 41, and the insertion portion 72 is bent approximately 90 degrees toward the inner surface side of the top plate 7 along the fold line 90. Thereafter, the insertion portion 72 is inserted into the slit 3a. As a result, the top plate 7 closes the upper opening surface of the body portion 10 and the contents are stored in the packaging box 1.

包装箱１に内容物が収納された商品を購入した顧客等は、天面板７上の切断部７１ａに沿って帯状部７１を天面板７から切り取ることによって天面板７を開いて内容物を取り出すことができる。そして、内容物を取り出した包装箱１を図５に示すように折曲部９３、９４で折り曲げて扁平に押し潰すことにより減容化を図ってゴミ容量を削減することができる。   A customer or the like who has purchased a product in which the contents are stored in the packaging box 1 opens the top plate 7 by removing the strip portion 71 from the top plate 7 along the cutting portion 71a on the top plate 7 and takes out the contents. be able to. Then, the packaging box 1 from which the contents are taken out can be reduced in volume by folding it at the bent portions 93 and 94 as shown in FIG.

なお、スリット３ａに挿入された挿入部７２を上方に引くと、係止部７２ａがスリット３ａの下端に係止される。この状態でさらに挿入部７２を上方に引くと、スリット３ａの周縁部の側面板３が破断し、または挿入部７２が切断部７１ａで天面板７から切り離される。したがって、開封した痕跡が天面板７に残るため、天面板７を介した内容物の改竄を容易に防止することができる。   When the insertion portion 72 inserted into the slit 3a is pulled upward, the locking portion 72a is locked to the lower end of the slit 3a. When the insertion portion 72 is further pulled upward in this state, the side plate 3 at the peripheral edge of the slit 3a is broken, or the insertion portion 72 is separated from the top plate 7 by the cutting portion 71a. Therefore, since the opened trace remains on the top plate 7, tampering of the contents through the top plate 7 can be easily prevented.

図９は包装箱１の底面部６を開いて改竄された後の状態を示す底面図である。底面部６において、例えば接着片６５ａの先端部を摘持して折畳み部９２の方向に力を加えて接着片６５ａを第２底面板６４から剥がすと、非切込み部８２に破断ＢＲ１が生じたり、切込み部８１と切込み部８３との間に破断ＢＲ２が生じたりする。また、対向部８２ａに隣接する切込み部８１と折畳み部９２との間に破断ＢＲ３が生じたりする。したがって、開封した痕跡が底面部６に残り、底面部６を介した内容物の改竄を容易に防止することができる。なお、接着片６３ａの先端部を摘持して折畳み部９２の方向に力を加えて接着片６３ａを第２底面板６２から剥がした場合にも破断ＢＲ１、ＢＲ２、ＢＲ３と同様な破断が接着片６３ａに生じる。   FIG. 9 is a bottom view showing the state after the bottom surface portion 6 of the packaging box 1 is opened and tampered. In the bottom surface portion 6, for example, when the front end portion of the adhesive piece 65 a is held and a force is applied in the direction of the folding portion 92 to peel the adhesive piece 65 a from the second bottom surface plate 64, a break BR1 may occur in the non-cut portion 82. The fracture BR2 may occur between the cut portion 81 and the cut portion 83. In addition, a fracture BR3 may occur between the cut portion 81 and the folding portion 92 adjacent to the facing portion 82a. Therefore, the opened trace remains on the bottom surface portion 6, and tampering of the contents through the bottom surface portion 6 can be easily prevented. Even when the adhesive piece 63a is gripped and force is applied in the direction of the folding portion 92 to peel off the adhesive piece 63a from the second bottom plate 62, the same breakage as that of the breaks BR1, BR2, and BR3 is adhered. It occurs in the piece 63a.

本実施形態によると、胴部１０の内部に向かって山折りされる折畳み部９２を折り戻し、第１底面板６３、６５が互いに係合して底面部６を形成するので、包装箱１を容易に組み立てることができる。また、複数の切込み部８１（第１切込み部）を非切込み部８２により連結した囲み部８０により接着片６３ａ、６５ａと第２底面板６２、６４との接着領域Ｂ１、Ａ１を囲み、第１底面板６３、６５と接着片６３ａ、６５ａとの間の折畳み部９２に対向した一の非切込み部８２から成る対向部８２ａが他の非切込み部８２よりも長く形成される。これにより、包装箱１を組み立てる過程で折畳み部９２に力が加わっても非切込み部８２の破断を防止することができる。したがって、包装箱１の組み立て性を低下させずに包装箱１に内容物を収納した商品の歩留まりを向上させることができる。   According to the present embodiment, the folding portion 92 that is folded inward toward the inside of the body portion 10 is folded back, and the first bottom surface plates 63 and 65 are engaged with each other to form the bottom surface portion 6. Can be easily assembled. In addition, a surrounding portion 80 in which a plurality of cut portions 81 (first cut portions) are connected by a non-cut portion 82 surrounds the bonding regions B1 and A1 between the adhesive pieces 63a and 65a and the second bottom surface plates 62 and 64, and the first A facing portion 82a including one non-cut portion 82 facing the folding portion 92 between the bottom plates 63, 65 and the adhesive pieces 63a, 65a is formed longer than the other non-cut portions 82. Thereby, even if force is applied to the folding part 92 in the process of assembling the packaging box 1, the non-cut part 82 can be prevented from breaking. Therefore, it is possible to improve the yield of products in which contents are stored in the packaging box 1 without degrading the assembling property of the packaging box 1.

また、囲み部８０の平面形状を折畳み部９２に対して一辺を傾斜した略矩形に形成するとともに、囲み部８０の一頂部に対向部８２ａを配置している。これにより、対向部８２ａを除く非切込み部８２は対向部８２ａよりも折畳み部９２から離れているため、折畳み部９２に力が加わっても破断しにくい。したがって、包装箱１の組み立て過程における非切込み部８２の破断を一層防止することができる。また、対向部８２ａの対角位置の頂部に切込み部８１を配置しているので、底面部６を開いて内容物を改竄した際に非切込み部８２が容易に破断し、一層容易に開封の痕跡を残すことができる。   In addition, the planar shape of the surrounding portion 80 is formed in a substantially rectangular shape with one side inclined with respect to the folding portion 92, and the facing portion 82 a is disposed at the top of the surrounding portion 80. Thereby, since the non-notch | incision part 82 except the opposing part 82a is separated from the folding part 92 rather than the opposing part 82a, even if force is added to the folding part 92, it is hard to fracture | rupture. Therefore, the breakage of the non-cut portion 82 in the assembly process of the packaging box 1 can be further prevented. Further, since the cut portion 81 is arranged at the top of the opposing portion 82a at the diagonal position, when the bottom surface portion 6 is opened and the contents are tampered with, the non-cut portion 82 is easily broken and can be opened more easily. Traces can be left.

また、囲み部８０が非切込み部８２に対向した切込みから成る切込み部８３（第２切込み部）を有するので、内容物を収納した包装箱１の底面部６を開いた際に切込み部８１と切込み部８３との間でも破断が生じる。したがって、包装箱１に収納された内容物の改竄を一層容易に防止することができる。   Moreover, since the surrounding part 80 has the notch part 83 (2nd notch part) which consists of a notch facing the non-notch part 82, when opening the bottom face part 6 of the packaging box 1 which stored the content, the notch part 81 and Breakage also occurs between the cut portion 83. Therefore, falsification of the contents stored in the packaging box 1 can be more easily prevented.

また、天面板７が先端部を折り線９０により折曲してスリット３ａ（第３切込み部）に挿入される挿入部７２と、ミシン目状の対向する一対の切断部７１ａにより切り取り可能に形成される帯状部７１とを有し、スリット３ａに挿入される挿入部７２がスリット３ａの下端に係止される係止部７２ａを有する。これにより、天面板７を確実に閉じることができるとともに、帯状部７１を切り取って包装箱１を容易に開封することができる。したがって、天面板７を開いた痕跡が天面板７に明確に残る。その結果、包装箱１の内容物の改竄を一層容易に防止することができる。   In addition, the top plate 7 is formed so that it can be cut off by an insertion portion 72 which is bent at a fold line 90 and inserted into the slit 3a (third cut portion) and a pair of perforated cutting portions 71a. The insertion portion 72 inserted into the slit 3a has a locking portion 72a locked to the lower end of the slit 3a. Thereby, while being able to close the top plate 7 reliably, the strip | belt-shaped part 71 can be cut out and the packaging box 1 can be opened easily. Therefore, a trace of opening the top plate 7 remains clearly on the top plate 7. As a result, falsification of the contents of the packaging box 1 can be more easily prevented.

また、切断部７１ａをスリット３ａ上に設けているので、挿入部７２を無理にスリット３ａから抜くと挿入部７２が切断部７１ａで破断する。したがって、天面板７を開いた痕跡が残り、包装箱１の内容物の改竄を一層容易に防止することができる。   Moreover, since the cutting part 71a is provided on the slit 3a, when the insertion part 72 is forcibly removed from the slit 3a, the insertion part 72 is broken at the cutting part 71a. Therefore, the trace which opened the top | upper surface board 7 remains, and the tampering of the contents of the packaging box 1 can be prevented still more easily.

なお、本実施形態において、囲み部８０の平面形状は矩形に限定されない。囲み部８０の平面形状を例えば円形、楕円形や多角形等に形成してもよい。また、囲み部８０の平面形状をＬ字状に形成してもよい。   In the present embodiment, the planar shape of the surrounding portion 80 is not limited to a rectangle. You may form the planar shape of the enclosure part 80 in circular, an ellipse, a polygon etc., for example. Further, the planar shape of the surrounding portion 80 may be formed in an L shape.

また、接着片６３ａ、６５ａの内面の全面に接着剤等を塗布してそれぞれ第２底面板６２、６４に接着してもよい。これにより、接着片６３ａ、６５ａの先端部を摘持しにくくなり、接着片６３ａ、６５ａを第２底面板６２、６４から剥がしにくくすることができる。したがって、包装箱１の内容物の改竄を一層確実に防止することができる。   Alternatively, an adhesive or the like may be applied to the entire inner surfaces of the adhesive pieces 63a and 65a and adhered to the second bottom surface plates 62 and 64, respectively. Thereby, it becomes difficult to hold the front ends of the adhesive pieces 63a and 65a, and the adhesive pieces 63a and 65a can be hardly peeled off from the second bottom surface plates 62 and 64. Therefore, falsification of the contents of the packaging box 1 can be prevented more reliably.

また、包装箱１の立体形状は、直方体に限定されず、例えば六角柱などでもよい。すなわち、オートボトム構造を有する多角注でもよい。   Moreover, the three-dimensional shape of the packaging box 1 is not limited to a rectangular parallelepiped, and may be a hexagonal column, for example. That is, it may be a polygonal note having an auto bottom structure.

本発明は、内容物を収納する包装箱に利用可能である。   The present invention can be used for a packaging box for storing contents.
