Description
本考案は、組立て包装箱に関し、詳しくは、段ボール板紙をトレー状に組立てることによって形成される包装箱に関する。 The present invention relates to an assembly packaging box, and more particularly to a packaging box formed by assembling corrugated paperboard into a tray shape.
従来、野菜や果物を出荷の際に包装するトレー状の包装箱が知られている。この種の包装箱として、従来から、図５及び図６に示す包装箱６１が知られている。包装箱６１は、所定形状に打抜かれた段ボール板紙６２を組み立てることによって形成される。 Conventionally, tray-like packaging boxes for packaging vegetables and fruits at the time of shipment are known. Conventionally, a packaging box 61 shown in FIGS. 5 and 6 is known as this type of packaging box. The packaging box 61 is formed by assembling corrugated paperboard 62 punched into a predetermined shape.
この包装箱６１は、矩形状の底板６３の左右の側縁に沿って折目線ａを介して連設された左右一対の外側板６４を起立させ、各外側板６４の先端縁に沿って折目線ｂ，ｃを介して連設された各内側板６５を外側板６４の内側に折返して重合させ、左右の各外側板６４の前後の側縁に折目線ｄを介して連設された第１舌片６６と、各内側板６５の前後の側縁に折目線ｅを介して連設された第２舌片６７とを、前記底板６３の前後の側縁に沿って内方に直角に折り曲げ、前記底板３の前後の側縁に沿って折目線ｆを介して連設された前後一対の側板６８を、前記第１舌片６６の外側に重合させて起立させ、前後の各側板６８の先端縁に沿って折目線ｇを介して連設された各桟板６９を内方に水平に折り曲げると共に、各桟板６９の左右の端縁に折目線ｈを介して連設された一対の係止片７０を該桟板６９に対して直角に折り曲げて前記外側板６４と内側板６５との間に形成された係止孔７１に挿入して係止させることにより組み立てられる。 The packaging box 61 is erected along a pair of left and right outer plates 64 connected along a crease line a along the left and right side edges of the rectangular bottom plate 63, and folded along the leading edge of each outer plate 64. The inner plates 65 connected through the lines b and c are folded and polymerized inside the outer plate 64, and the inner plates 65 are connected to the front and rear side edges of the left and right outer plates 64 through the fold line d. The first tongue piece 66 and the second tongue piece 67 connected to the front and rear side edges of each inner plate 65 via the fold line e are perpendicular to the inner side along the front and rear side edges of the bottom plate 63. A pair of front and rear side plates 68 that are bent and connected along the front and rear side edges of the bottom plate 3 via a crease line f are superposed on the outside of the first tongue piece 66 to stand up, and the front and rear side plates 68. Each of the crosspieces 69 connected along the crease line g along the front end edge of the crosspiece is bent horizontally inward and folded at the left and right end edges of each crosspiece 69. A pair of locking pieces 70 provided continuously through the line h are bent at a right angle with respect to the crosspiece 69 and inserted into a locking hole 71 formed between the outer plate 64 and the inner plate 65. Assembled by locking.
この包装箱６１は、上記のように左右の側板を外側板６４及び内側板６５の二重に構成することで包装箱を複数積み重ねた際の座屈強度を向上させている。そして、その内側板６５を外側板６４に対して重合させた状態で維持するために、左右の各第２舌片６７は、組み立てられたときに先端部が一部重複可能な長さに形成され、さらに、この各先端部に上下互い違いの方向からスリット７２を設け、該スリット７２同士を差し込んで掛合させることで、左右の内側板６４を連結して、包装箱の組立状態を維持している。 As described above, the packaging box 61 is configured such that the left and right side plates are doubled by the outer plate 64 and the inner plate 65, thereby improving the buckling strength when a plurality of packaging boxes are stacked. In order to maintain the inner plate 65 in a state of being superposed on the outer plate 64, each of the left and right second tongue pieces 67 is formed to have a length that allows the tip portion to partially overlap when assembled. Furthermore, by providing slits 72 in the respective top and bottom alternate directions, and inserting and engaging the slits 72, the left and right inner plates 64 are connected to maintain the assembled state of the packaging box. Yes.
しかしながら、この従来の包装箱では、第２舌片が重複するほど長くなければならず、段ボールの使用量が多く、材料コスト高いという不都合がある。 However, this conventional packaging box must be long enough to overlap the second tongue piece, which has the disadvantage that the amount of cardboard used is large and the material cost is high.
上記の点に鑑み、本考案は、複数の包装箱を積み重ねた際の座屈強度を維持しつつ、段ボールの使用量を少なくして材料コストを削減できる組立て包装箱を提供することを目的とする。 In view of the above points, an object of the present invention is to provide an assembly packaging box that can reduce the material cost by reducing the amount of cardboard used while maintaining the buckling strength when a plurality of packaging boxes are stacked. To do.
かかる目的を達成するために、本考案の組立て包装箱は、矩形状の底板の左右の側縁に沿って折目線を介して連設された左右一対の外側板が起立し、各外側板の先端縁に沿って折目線を介して連設された各内側板が外側板の内側に折返されて重合し、左右の各外側板の前後の側縁に折目線を介して連設された舌片が、前記底板の前後の側縁に沿って内方に直角に折り曲がり、前記底板の前後の側縁に沿って折目線を介して連設された前後一対の側板が、前記舌片の外側に重合されて起立し、前後の各側板の先端縁に沿って折目線を介して連設された各桟板が内方に水平に折り曲がると共に、各桟板の左右の端縁に折目線を介して連設された一対の係止片が、該桟板に対して直角に折り曲がり、前記外側板と前記内側板との間に形成された係止孔に挿入されて係止される組立て包装箱において、左右の各外側板には第１貫通孔が形成され、左右の各内側板の前記第１貫通孔に対向する位置には第２貫通孔が形成され、前記第１貫通孔及び前記第２貫通孔の少なくとも一方は、一部が折り曲げ部により折り曲げ可能な閉塞片により閉塞され、該閉塞片は折り曲げて対向する他方の貫通孔に挿入されて係止されることを特徴とする。 In order to achieve such an object, the assembly packaging box according to the present invention has a pair of left and right outer plates standing along a crease line along the left and right side edges of a rectangular bottom plate, Tongues that are connected to each other on the front and rear side edges of each of the left and right outer plates via the crease line. A pair of front and rear side plates bent inward at right angles along the front and rear side edges of the bottom plate, and connected in a crease line along the front and rear side edges of the bottom plate, Each of the crosspieces that are superimposed on the outside and stand up and are continuously connected along the crease line along the front edge of each of the front and rear side plates are folded inward and folded at the left and right edges of each crosspiece. A pair of locking pieces provided continuously through the line of sight are bent at right angles to the crosspiece, and are formed between the outer plate and the inner plate. In the assembly packaging box that is inserted and locked to the left and right outer plates, the first through holes are formed in the left and right outer plates, and the second through holes are formed at positions facing the first through holes of the left and right inner plates. And at least one of the first through-hole and the second through-hole is partially closed by a closing piece that can be bent by a bending portion, and the closing piece is bent and inserted into the other through-hole facing each other. It is locked.
本考案の組立て包装箱によれば、内側板が外側板の内側に折り返して重合させた状態で、外側板及び内側板の少なくとも一方に設けられた閉塞片を折り曲げて、対向する他方の貫通孔に挿入して係止させる。このため、従来の組立て包装箱と同様に、左右の側板が外側板及び内側板が二重に構成された状態で組立状態が維持されるため、複数の包装箱を積み重ねた際の座屈強度が維持されている。 According to the assembly packaging box of the present invention, in the state where the inner plate is folded and polymerized inside the outer plate, the closing piece provided on at least one of the outer plate and the inner plate is folded, and the other through-hole facing the other Insert and lock. For this reason, as in the case of the conventional assembly packaging box, the left and right side plates are maintained in an assembled state in which the outer plate and the inner plate are doubled, so that the buckling strength when stacking a plurality of packaging boxes is stacked. Is maintained.
従来、内側板に連設されていた第２舌片を設ける必要がなく、段ボールの使用量を少なくして材料コストを削減できる。 Conventionally, there is no need to provide a second tongue piece that is continuously provided on the inner plate, and the material cost can be reduced by reducing the amount of cardboard used.
また、本考案の組立て包装箱において、前記閉塞片は、前記折り曲げ部の両端から、各外側板の先端縁から離れるにつれて、互いに離反する方向に傾斜して延びる一対の外縁部を有するように形成され、該閉塞片が挿入される貫通孔は、前記外縁部に対応する位置において、各外側板の先端縁から離れるにつれて、互いに離反する方向に傾斜して延びる一対の内縁部が形成されているのが好ましい。 Further, in the assembly packaging box of the present invention, the closing piece is formed so as to have a pair of outer edge portions extending obliquely away from each other in a direction away from the leading edge of each outer plate from both ends of the bent portion. The through-hole into which the closing piece is inserted is formed with a pair of inner edge portions extending at an angle in a direction away from each other as the distance from the front edge of each outer plate is increased at a position corresponding to the outer edge portion. Is preferred.
これによれば、閉塞片が貫通孔に挿入された状態で、内側板が外側板から離れる方向に向かう力が付与されると、閉塞片の傾斜した前記外縁部が該貫通孔の前記内縁部に沿って、貫通孔の幅狭となる方向に摺接され、該貫通孔への閉塞片の係止状態を一層強固とすることができる。 According to this, when a force is applied to the inner plate in a direction away from the outer plate in a state where the closing piece is inserted into the through hole, the inclined outer edge portion of the closing piece becomes the inner edge portion of the through hole. The through-holes are slidably contacted in the direction in which the through-holes are narrowed, and the locking state of the closing pieces to the through-holes can be further strengthened.
本考案の第１実施形態の組立て包装箱１は、一般に桟付き箱と言われ、図１に示すように、トレー状に組立てられて図示しない野菜や果物等を出荷の際に包装するものである。 The assembly packaging box 1 according to the first embodiment of the present invention is generally referred to as a box with a cross, and as shown in FIG. 1, it is assembled in a tray and wraps vegetables and fruits not shown at the time of shipment. is there.
該包装箱１は、図２に示すように、打抜き形成された段ボール板紙２によって組立てられる。該段ボール板紙２は、図示するように、左右対称且つ前後対称に形成されている。即ち、矩形状の底板３を備え、該底板３の左右の側縁には折目線ａを介して一対の左右側板４（外側板）が連設されている。左右側板４の先端縁には平行する一対の折目線ｂ，ｃを介して内側板５が連設されている。左右側板４の前後の側縁には折目線ｄを介して一対の舌片６が連設されている。 As shown in FIG. 2, the packaging box 1 is assembled by corrugated paperboard 2 formed by punching. As shown in the drawing, the corrugated paperboard 2 is formed symmetrically in the left-right direction and in the front-rear direction. That is, a rectangular bottom plate 3 is provided, and a pair of left and right side plates 4 (outer plates) are connected to left and right side edges of the bottom plate 3 via a crease line a. An inner plate 5 is connected to the front edge of the left right plate 4 via a pair of parallel crease lines b and c. A pair of tongue pieces 6 are connected to the front and rear side edges of the left right plate 4 via a crease line d.
また、前記底板３の前後の側縁には折目線ｅを介して一対の前後側板８が連設されている。前後側板８の先端縁には折目線ｆを介して桟板９が連設されている。該桟板９の左右の端縁には折目線ｇを介して一対の係止片１０が連設されている。 A pair of front and rear side plates 8 are connected to the front and rear side edges of the bottom plate 3 via a fold line e. A crosspiece 9 is connected to the front edge of the front / rear side plate 8 via a crease line f. A pair of locking pieces 10 are connected to the left and right edges of the crosspiece 9 via a crease line g.
一対の折目線ｂ，ｃの間には、各折目線ｂ，ｃに沿って一対の係止孔１１が夫々形成されている。係止孔１１は、図１に示す形状に包装箱１を組立てるとき、前記係止片１０の挿入位置に形成されている。 Between the pair of crease lines b and c, a pair of locking holes 11 are formed along the crease lines b and c, respectively. The locking hole 11 is formed at the insertion position of the locking piece 10 when the packaging box 1 is assembled into the shape shown in FIG.
また、左右側板４の中央部には、台形状の第１貫通孔１２が形成されており、内側板５の先端縁には、台形状の第２貫通孔１３が形成されている。 A trapezoidal first through hole 12 is formed at the center of the left and right side plates 4, and a trapezoidal second through hole 13 is formed at the leading edge of the inner plate 5.
なお、該第１実施形態では、第２貫通孔１３は、台形状の底部に相当する内縁部が存在しないため、所謂切欠きとして形成されている。つまり、本考案における第２貫通孔１３は、一部が開放された切欠きも含む概念である。 In the first embodiment, the second through-hole 13 is formed as a so-called notch because there is no inner edge corresponding to the trapezoidal bottom. That is, the 2nd through-hole 13 in this invention is a concept also including the notch which one part opened.
前記第２貫通孔は、折目線ｃに平行な折り曲げ部ｈにより折り曲げ可能な閉塞片１４により閉塞されている。 The second through hole is closed by a closing piece 14 that can be bent by a bent portion h parallel to the crease line c.
前記第１貫通孔１２は、内側板５の閉塞片１４が折返されたときに、閉塞片１４が挿入されて係止されるように設けられている。 The first through hole 12 is provided so that the closing piece 14 is inserted and locked when the closing piece 14 of the inner plate 5 is folded back.
次に、以上の構成からなる包装箱１の組立て工程を説明する。 Next, the assembly process of the packaging box 1 having the above configuration will be described.
先ず、左右側板４を折目線ａを介して折り曲げ起立させる。このとき、該左右側板４と共に内側板５が立ち上げられる。 First, the left and right side plates 4 are bent and raised through the crease line a. At this time, the inner plate 5 is raised together with the left and right side plates 4.
次に、内側板５を折目線ｂ，ｃを介して内側に折返す。これにより、左右側板４と内側板５とが重合し、左右側板４及び内側板５の上縁の両端部に前記係止孔１１が形成される。該係止孔１１は後述するように桟板９に設けられた係止片１０が挿入係止されるものである。 Next, the inner plate 5 is folded inward via the crease lines b and c. As a result, the left and right side plates 4 and the inner plate 5 are overlapped, and the locking holes 11 are formed at both ends of the upper edges of the left and right side plates 4 and the inner plate 5. As will be described later, the locking hole 11 is for inserting and locking a locking piece 10 provided in the crosspiece 9.
さらに、内側板５の閉塞片１４を折り曲げ部ｈを介して外側に折り曲げる。これにより、閉塞片１４は、左右側板４の第１貫通孔１２に挿入され、図１に示すように、第１貫通孔１２の内縁に係止される。 Further, the closing piece 14 of the inner plate 5 is bent outward through the bent portion h. Thus, the closing piece 14 is inserted into the first through hole 12 of the left and right side plates 4 and is locked to the inner edge of the first through hole 12 as shown in FIG.
次に、舌片６を折目線ｄを介して内方に直角に折り曲げる。 Next, the tongue piece 6 is bent at a right angle inward through the crease line d.
次に、前後側板８を折目線ｅを介して折り曲げ起立させる。そして、前記桟板９を折目線ｆを介して内方に水平となるように折り曲げる。このとき、該桟板９に連設された係止片１０を折目線ｇを介して折り曲げ、係止孔１１に挿入する。 Next, the front and rear side plates 8 are bent and raised through the crease line e. And the said crosspiece 9 is bent so that it may become inward horizontal via the crease line f. At this time, the locking piece 10 connected to the crosspiece 9 is bent through the crease line g and inserted into the locking hole 11.
このようにして形成された包装箱１は、図１に示すように、内側板５の前記閉塞片１４が左右側板４の第１貫通孔１２に係止されていることによって、内側板５が左右側板４に連結保持される。そして、桟板９の係止片１０を介して左右側板４及び内側板５と前後側板８とが連結保持された状態となる。 As shown in FIG. 1, the packaging box 1 formed in this way has the inner plate 5 formed by the closure piece 14 of the inner plate 5 being engaged with the first through holes 12 of the left and right side plates 4. The left and right plates 4 are connected and held. Then, the left and right side plates 4 and the inner side plate 5 and the front and rear side plates 8 are connected and held via the locking piece 10 of the crosspiece 9.
これにより、包装箱１は、従来の組立て包装箱と同様に、左右側板４と内側板５とが二重に構成されて組立状態が維持されるため、複数の包装箱を積み重ねた際の座屈強度が維持されている。また、従来、内側板に連設されていた第２舌片を設ける必要がないため、段ボールの使用量を少なくして材料コストを削減できる。 Thereby, since the packaging box 1 maintains the assembly state because the left and right side plates 4 and the inner side plate 5 are doubled as in the conventional assembly packaging box, the seat when the plurality of packaging boxes are stacked is provided. The bending strength is maintained. Moreover, since it is not necessary to provide the 2nd tongue piece conventionally connected with the inner side board, the usage-amount of corrugated cardboard can be decreased and material cost can be reduced.
さらに、該第１実施形態では、図１における内側板５の高さ方向の長さを、閉塞片１４の台形状の下底部の延長線に沿うように短くできるので、段ボールの使用量をさらに少なくして材料コストを削減できる。 Furthermore, in the first embodiment, since the length in the height direction of the inner plate 5 in FIG. 1 can be shortened along the extension line of the trapezoidal bottom bottom of the closing piece 14, the amount of cardboard used can be further increased. Less material costs can be saved.
また、閉塞片１４及び第１貫通孔１２は、折目線ｂ，ｃから夫々所定の間隔を存して上底部が対向する台形状に形成されている。このため、閉塞片１４が第１貫通孔１２に挿入された状態で、内側板５が左右側板４から離れる方向に向かう力（図１示の折り返された状態から、図２示の元の状態に戻る力）が付与されると、閉塞片１４の台形状の脚部に相当する外縁部１４ｌが、第１貫通孔１２の台形状の脚部に相当する内縁部１２ｌに沿って、第１貫通孔１２の台形状の上底部となる方向に摺接される。この結果、第１貫通孔１２への閉塞片１４の係止状態を一層強固とすることができる。 Further, the closing piece 14 and the first through hole 12 are formed in a trapezoidal shape with the upper bottom facing each other with a predetermined distance from the crease lines b and c. For this reason, in the state where the closing piece 14 is inserted into the first through-hole 12, the force toward the direction in which the inner plate 5 is separated from the left and right side plates 4 (from the folded state shown in FIG. 1 to the original state shown in FIG. 2) Is applied to the outer edge portion 141 corresponding to the trapezoidal leg portion of the closing piece 14 along the inner edge portion 121 corresponding to the trapezoidal leg portion of the first through hole 12. The through hole 12 is slidably contacted in the direction of the trapezoidal upper base. As a result, the locking state of the closing piece 14 to the first through hole 12 can be further strengthened.
なお、第１実施形態では、閉塞片１４と第１貫通孔１２とは、同一の形状としたが、本考案はこれに限られず、閉塞片１４が第１貫通孔１２に係止可能な形状であれば足りる。また、第１実施形態の包装箱１は、段ボール板紙を材料とするのが好ましいが、段ボール以外の厚手の板紙でも形成できる。 In the first embodiment, the closing piece 14 and the first through hole 12 have the same shape. However, the present invention is not limited to this, and the closing piece 14 can be locked to the first through hole 12. If it is enough. In addition, the packaging box 1 of the first embodiment is preferably made of corrugated paperboard, but can be formed of thick paperboard other than cardboard.
続いて、第１実施形態と同様の効果が得られる実施形態として、図３Ａ及び図３Ｂに示す第２実施形態、及び、図４に示す第３実施形態を例に挙げて説明する。 Subsequently, as an embodiment in which the same effect as the first embodiment can be obtained, the second embodiment shown in FIGS. 3A and 3B and the third embodiment shown in FIG. 4 will be described as examples.
第２実施形態では、図３Ａ及び３Ｂに示すように、内側板５’の高さ方向の長さを、左右側板４の高さ方向の長さと実質的に一致させている。
これにより、段ボールの使用量をさらに少なくして材料コストを削減できる。
これにより、第２実施形態の包装箱１は、内側板に連設されていた第２舌片を設ける必要がないため、段ボールの使用量を少なくして材料コストを削減できる。また、内側板５の先端縁が、底板３に接触できるため、複数の包装箱を積み重ねた際の座屈強度がさらに維持されている。
In the second embodiment, as shown in FIGS. 3A and 3B, the length in the height direction of the inner plate 5 ′ is substantially matched with the length in the height direction of the left and right side plates 4.
Thereby, the usage amount of cardboard can be further reduced, and the material cost can be reduced.
Thereby, since the packaging box 1 of 2nd Embodiment does not need to provide the 2nd tongue piece connected with the inner side board, the usage-amount of a cardboard can be decreased and material cost can be reduced. Moreover, since the front-end edge of the inner side plate 5 can contact the bottom plate 3, the buckling strength at the time of stacking a plurality of packaging boxes is further maintained.
また、第１実施形態及び第２実施形態においては、内側板５、５’側の第２貫通孔１３に閉塞片１４を設けたものを示したが、図４に示す第３実施形態のように、第１貫通孔１２側に閉塞片１４’を設けてもよい。 Moreover, in 1st Embodiment and 2nd Embodiment, although what provided the obstruction piece 14 in the 2nd through-hole 13 by the side of the inner side board 5 and 5 'was shown, like 3rd Embodiment shown in FIG. Moreover, you may provide obstruction | occlusion piece 14 'in the 1st through-hole 12 side.
さらに、第１貫通孔１２及び第２貫通孔１３の両方に、閉塞片１４を設け、外側・内側のどちらにでも折り曲げて係止できるように構成することもできる。 Furthermore, the closing piece 14 can be provided in both the first through-hole 12 and the second through-hole 13 so that it can be bent and locked on either the outside or the inside.
