Description

本発明は、連結箱に関し、特に、2個の包装箱の一側面同士を突き合わせて連結してなる連結箱に関する。   The present invention relates to a connection box, and more particularly to a connection box formed by abutting and connecting one side surfaces of two packaging boxes.

製品の輸送や保管に際して、外装段ボールなどの包装箱に対し、高い圧縮強度が求められる場合がある。例えば、柔軟なフィルムで構成される軟包装材(いわゆるフレキシブルパッケージ)を用いた製品の輸送や保管では、製品自体の耐荷重性が低いため、圧縮強度の高い包装箱を用いて製品を保護する必要がある。   When a product is transported or stored, a high compressive strength may be required for a packaging box such as an outer corrugated cardboard. For example, in the transportation and storage of products using flexible packaging materials (so-called flexible packages) made of flexible films, the products themselves are low in load resistance, so the products are protected using packaging boxes with high compressive strength. There is a need.

このように、高い圧縮強度が包装箱に求められる場合、包装箱の構成材料に強度の高い材料を使用すれば、容易に圧縮強度を高めることができる。しかし、構成材料に強度の高い材料を使用すると、強度を高めた分、資材コストが単に高くなる。このため、資材コストをできるだけ上げずに、包装箱の圧縮強度を高めることが望まれる。従来、包装箱の断面形状を工夫することで、包装箱の圧縮強度を高める技術が各種提案されている(例えば、特許文献1参照)。   Thus, when high compressive strength is calculated | required by a packaging box, if a material with high intensity | strength is used for the constituent material of a packaging box, compressive strength can be raised easily. However, when a material having high strength is used as the constituent material, the material cost is simply increased by the increase in strength. For this reason, it is desired to increase the compressive strength of the packaging box without increasing the material cost as much as possible. Conventionally, various techniques for increasing the compressive strength of the packaging box by devising the cross-sectional shape of the packaging box have been proposed (see, for example, Patent Document 1).

特許文献1には、八角形のマンドレルと、このマンドレルに合わさる加圧プレートとを用い、薄板材をマンドレルと加圧プレートの間に挟んで八角形に折り曲げることによって、水平断面が八角形に形成されたケースを製造する技術が記載されている。この八角形に形成されたケースでは、面取り状の補強部によって四隅が補強されるため、水平断面を矩形に形成したケースに比べ、高い圧縮強度を得ることができる。   In Patent Document 1, an octagonal mandrel and a pressure plate fitted to the mandrel are used, and a thin plate material is sandwiched between the mandrel and the pressure plate and bent into an octagon, thereby forming a horizontal cross section into an octagon. Techniques for manufacturing the case made are described. In this octagonal case, since the four corners are reinforced by the chamfered reinforcing portion, a high compressive strength can be obtained compared to a case where the horizontal cross section is rectangular.

ところで、特許文献1に記載されるケースでは、面取り状の補強部が形成されることによって、ケースの内容積が減る。このため、ケースに収納できる製品の個数が矩形のケースに比べて減ってしまい、輸送効率が悪い。   By the way, in the case described in Patent Document 1, the internal volume of the case is reduced by forming the chamfered reinforcing portion. For this reason, the number of products that can be stored in the case is reduced as compared with the rectangular case, and transportation efficiency is poor.

この輸送効率の問題を解消するには、2個の包装箱を連結して輸送することが有効である。2個の包装箱を連結した連結箱では、収納できる製品の個数が倍増できることに加え、1個の荷箱として取り扱われるため、輸送コストの削減を図ることもできる。しかし、いわゆるPPバンドなどの副資材を用いて2個の包装箱を連結すると、資材コストが嵩む。資材コストを低く抑えるには、副資材を使用せずに、2個の包装箱同士を連結することが好適である。   In order to solve this problem of transportation efficiency, it is effective to connect two packaging boxes for transportation. In the connection box in which two packaging boxes are connected, the number of products that can be stored can be doubled and handled as one packing box, so that the transportation cost can be reduced. However, if two packaging boxes are connected using a secondary material such as a so-called PP band, the material cost increases. In order to keep material costs low, it is preferable to connect two packaging boxes without using secondary materials.

そこで、特許文献2には、2個の箱体を並立させて側面を互いに突き合わせ、一方の箱体に設けた欠除部に、他方の箱体に設けた接続片を嵌め合わせることで、2個の箱体を連結させる技術が開示されている。この特許文献2の連結技術によれば、副資材を使用せずに2個の箱体同士を連結することができる。   Therefore, in Patent Document 2, two box bodies are juxtaposed, the side surfaces are butted together, and a connecting piece provided in the other box body is fitted into a notch portion provided in one box body, thereby 2 A technique for connecting individual boxes is disclosed. According to the connection technique of Patent Document 2, two boxes can be connected without using a secondary material.

ここで、特許文献2の技術に代表される従来の連結構造を用いて、水平断面が八角形の包装箱を連結する場合について検討する。   Here, the case where the packaging box whose horizontal cross section is an octagon is connected using the conventional connection structure represented by the technique of patent document 2 is examined.

図7は、従来の連結構造を用いて連結した連結箱の水平断面図である。
図7に示すように、2個の包装箱100は、各々、対向する2組の側壁101,102と、隣り合う側壁101,102の間に設けられる合計4個の面取り状の補強部103とからなり、水平断面が八角形に形成される。側壁102には、連結相手の側壁102に沿って延びる接続片104が設けられる。2個の包装箱100は、各々、側壁101同士を突き合わせた状態で、接続片104が連結相手の側壁102に接着される。これにより、水平断面が八角形の包装箱100を2個連結してなる連結箱200を得ることができる。
FIG. 7 is a horizontal cross-sectional view of a connection box connected using a conventional connection structure.
As shown in FIG. 7, each of the two packaging boxes 100 includes two sets of opposing side walls 101 and 102 and a total of four chamfered reinforcing portions 103 provided between the adjacent side walls 101 and 102. The horizontal section is formed in an octagon. The side wall 102 is provided with a connection piece 104 extending along the side wall 102 of the connection partner. In each of the two packaging boxes 100, the connection piece 104 is bonded to the coupling partner side wall 102 in a state where the side walls 101 are abutted with each other. Thereby, the connection box 200 formed by connecting two packaging boxes 100 having an octagonal horizontal section can be obtained.

特開平11−263330号公報Japanese Patent Laid-Open No. 11-263330 特開平7−285539号公報JP-A-7-285539

しかしながら、連結箱200においては、補強部103の大きさに応じた隙間201が接続片104の内側に形成されるため、接続片104が大型化するという問題が生じる。すなわち、隙間201が形成されるため、水平断面が矩形の包装箱を連結する場合に比べて、接続片104を余計に延ばす必要があり、資材コストが高くなる。   However, since the gap 201 corresponding to the size of the reinforcing portion 103 is formed inside the connection piece 104 in the connection box 200, there arises a problem that the connection piece 104 is enlarged. That is, since the gap 201 is formed, it is necessary to extend the connecting piece 104 more than in the case of connecting packaging boxes having a rectangular horizontal cross section, and the material cost is increased.

したがって、資材コストを低く抑えつつ、補強部を有する包装箱を連結できる技術が望まれる。   Therefore, a technique capable of connecting packaging boxes having reinforcing portions while suppressing material costs is desired.

本発明は、このような事情に鑑みてなされたものであり、その目的は、資材コストを低く抑えることができる共に圧縮強度を高めることができ、しかも高い輸送効率が得られる連結箱を提供することにある。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a junction box that can keep material costs low and increase the compressive strength, and that can obtain high transport efficiency. There is.

本発明の連結箱は、2個の包装箱の一側面同士を突き合わせて連結してなる連結箱において、前記包装箱は、周壁と、前記周壁の下端を塞ぐ底壁と、前記周壁の上端を塞ぐ上壁と、を有し、前記周壁は、前記一側面を形成する前壁と、前記前壁に対向する後壁と、一端が前記前壁に略直角に連なり他端が前記後壁に連なる1対の側壁と、前記連結箱の対角線上に位置して前記周壁の圧縮強度を高める補強部と、前記側壁の一端に切り取り線を介して設けられ連結相手の側壁に重なるように延びて固定される接続部と、を有することを特徴とする。   The connection box of the present invention is a connection box formed by abutting and connecting one side surfaces of two packaging boxes, wherein the packaging box includes a peripheral wall, a bottom wall closing the lower end of the peripheral wall, and an upper end of the peripheral wall. An upper wall that closes, and the peripheral wall includes a front wall that forms the one side surface, a rear wall that faces the front wall, one end connected to the front wall at a substantially right angle, and the other end connected to the rear wall. A pair of side walls, a reinforcing portion that is positioned on a diagonal line of the connection box to increase the compressive strength of the peripheral wall, and is provided at one end of the side wall with a cut line extending so as to overlap the side wall of the connection partner. And a connection portion to be fixed.

この構成により、側壁の一端が前壁に略直角に連なるため、接続部の内側には、隙間が形成されない。これにより、小さい接続部であっても2個の包装箱をしっかりと連結することができ、資材コストを低く抑えることができる。一方、側壁の他端(連結箱の対角線上)に補強部を設けたので、この補強部によって周壁の圧縮強度を高めることができる。すなわち、本発明の連結箱では、側壁の一端では、補強部を設けずに連結し易い構造を採用する一方、側壁の他端では、補強部を設けて圧縮強度を高める構造を採用した。
また、側壁の一端に補強部を設けない分、従来の八角形の包装箱に比べて、包装箱に収納できる製品の個数が増える。これにより、輸送効率を一層高めることができる。
With this configuration, since one end of the side wall is connected to the front wall at a substantially right angle, no gap is formed inside the connection portion. Thereby, even if it is a small connection part, two packaging boxes can be connected firmly and material cost can be held down low. On the other hand, since the reinforcement part was provided in the other end (on the diagonal line of a connection box) of a side wall, the compressive strength of a surrounding wall can be raised with this reinforcement part. That is, the connection box of the present invention employs a structure that facilitates connection without providing a reinforcing portion at one end of the side wall, while adopting a structure that increases the compressive strength by providing a reinforcing portion at the other end of the side wall.
Further, since the reinforcing portion is not provided at one end of the side wall, the number of products that can be stored in the packaging box is increased as compared with the conventional octagonal packaging box. Thereby, transportation efficiency can further be improved.

上記発明の連結箱では、前記接続部は、前記上壁の上面から下方に離間して設けられることを特徴とする。   In the junction box according to the invention, the connection portion is provided to be spaced downward from the upper surface of the upper wall.

この構成により、複数の連結箱を上下方向に積み付けて輸送あるいは保管する際、上壁には荷重が加わるが、接続部には荷重が加わらない。
仮に、接続部が上壁と同じ高さ位置にある場合、接続部にも荷重が加わってしまう。接続部に荷重が加わると、本来、開梱時に切断される切り取り線が切断されるおそれがある。
この点、上記発明の連結箱では、接続部に荷重が加わらないため、切り取り線の切断を防ぐことができ、輸送時あるいは保管時において、連結箱の連結強度を良好に維持することができる。
With this configuration, when a plurality of connection boxes are stacked and transported or stored in the vertical direction, a load is applied to the upper wall, but no load is applied to the connection portion.
If the connecting portion is at the same height as the upper wall, a load is also applied to the connecting portion. When a load is applied to the connecting portion, the tear line that is originally cut when unpacking may be cut.
In this regard, in the connection box of the above invention, since no load is applied to the connection portion, the cut line can be prevented from being cut, and the connection strength of the connection box can be maintained well during transportation or storage.

上記発明の連結箱では、前記補強部は、面取り状に折り曲げられる壁であり、前記上壁および前記底壁のそれぞれには、前記補強部の上端および下端に合わさって前記補強部の折り曲げ角を正規の角度に規制する角度規制部が設けられることを特徴とする。   In the junction box of the above invention, the reinforcing portion is a wall that is bent in a chamfered shape, and the upper wall and the bottom wall are respectively fitted with the upper end and the lower end of the reinforcing portion so that the bending angle of the reinforcing portion is set. An angle restricting portion for restricting to a regular angle is provided.

この構成により、補強部の上端および下端に角度規制部が合わさることで、補強部の折り曲げ角が正規の角度に規制されるようになる。
これに対し、従来は、補強部の折り曲げ角度を正規の角度にするために、型を用いて、段ボールシートを折り曲げるようにしていた。この場合、型の費用に加え、製造工程も増えるため、製造コストが高くなる。
この点、上記発明の連結箱では、補強部の折り曲げ角を正規の角度に容易に規制できるので、補強部を折り曲げるための専用の型および工程が不要になる。したがって、製造コストを低く抑えることができる。
With this configuration, the angle restriction portion is combined with the upper end and the lower end of the reinforcement portion, so that the bending angle of the reinforcement portion is restricted to a normal angle.
On the other hand, conventionally, in order to make the bending angle of the reinforcing portion a normal angle, the corrugated cardboard sheet is bent using a mold. In this case, since the manufacturing process increases in addition to the cost of the mold, the manufacturing cost increases.
In this regard, in the connection box of the above invention, the bending angle of the reinforcing portion can be easily regulated to a regular angle, so that a dedicated mold and process for bending the reinforcing portion are not necessary. Therefore, the manufacturing cost can be kept low.

本発明によれば、資材コストを低く抑えることができる共に圧縮強度を高めることができ、しかも高い輸送効率が得られる連結箱を提供することができる。   According to the present invention, it is possible to provide a junction box that can keep the material cost low and increase the compressive strength and obtain high transport efficiency.

Note that the same number is assigned to the same element throughout the description of the embodiment. The drawings are viewed in the direction of the reference numerals. In the embodiment, “upper”, “lower”, “front”, “rear”, “left”, “right” each looked at the other packaging box that is the connection partner from one packaging box. Indicates the direction of time.

図1に示すように、実施形態の連結箱10は、2個の包装箱20の一側面21(図2参照)同士を突き合わせて連結したものである。2個の包装箱20は、略同一形態に形成され、各々、連結相手の包装箱20に対して鉛直軸を中心に180°反転させた方向を向いている。   As shown in FIG. 1, the connection box 10 of the embodiment is formed by abutting and connecting one side surfaces 21 (see FIG. 2) of two packaging boxes 20. The two packaging boxes 20 are formed in substantially the same form, and each is directed to a direction that is inverted by 180 ° around the vertical axis with respect to the packaging box 20 of the connection partner.

包装箱20の構成を図2、図3に基づいて説明する。
図2に示すように、2個の包装箱20の各々は、周壁30と、周壁30の下端を塞ぐ底壁22と、周壁30の上端を塞ぐ上壁23(図1参照)とを有する。周壁30は、前壁25、後壁26、左右1対の側壁27および左右1対の補強部28によって構成される。
The structure of the packaging box 20 is demonstrated based on FIG. 2, FIG.
As shown in FIG. 2, each of the two packaging boxes 20 includes a peripheral wall 30, a bottom wall 22 that closes the lower end of the peripheral wall 30, and an upper wall 23 (see FIG. 1) that closes the upper end of the peripheral wall 30. The peripheral wall 30 includes a front wall 25, a rear wall 26, a pair of left and right side walls 27, and a pair of left and right reinforcing portions 28.

図3に示すように、前壁25は、前記一側面21を形成する壁である。前壁25は、例えば、正面視で略長方形あるいは略正方形に形成される。   As shown in FIG. 3, the front wall 25 is a wall forming the one side surface 21. The front wall 25 is formed in, for example, a substantially rectangular shape or a substantially square shape when viewed from the front.

後壁26は、前壁25に対向する壁であり、後壁26の左右方向の幅は、前壁25の幅よりも小さい。後壁26は、例えば、背面視で略長方形あるいは略正方形に形成される。   The rear wall 26 is a wall facing the front wall 25, and the width of the rear wall 26 in the left-right direction is smaller than the width of the front wall 25. The rear wall 26 is formed in, for example, a substantially rectangular shape or a substantially square shape when viewed from the back.

1対の側壁27の各々は、例えば、側面視で略長方形あるいは略正方形に形成され、前端が前壁25に略直角に連なり、後端が補強部28を介して後壁26に連なる。さらに、1対の側壁27のうち一方の側壁27の前端には、接続部31が突出して設けられる。   Each of the pair of side walls 27 is formed in, for example, a substantially rectangular shape or a substantially square shape in a side view, the front end is connected to the front wall 25 at a substantially right angle, and the rear end is connected to the rear wall 26 via the reinforcing portion 28. Further, a connecting portion 31 is provided to project from the front end of one side wall 27 of the pair of side walls 27.

この接続部31は、上下方向に延びる切り取り線32を介して側壁27の前端に連なる。接続部31は、切り取り線32から連結相手の側壁27に向けて延び、ホットメルトなどの接着剤で固定される。接続部31の形状は、任意であるが、ここでは、上下方向に細長い略長方形に形成される。また、接続部31は、上壁23の上面から下方に距離Lだけ離間して設けられる。   This connection part 31 continues to the front end of the side wall 27 via a cut line 32 extending in the vertical direction. The connecting portion 31 extends from the cut line 32 toward the side wall 27 of the connection partner, and is fixed with an adhesive such as hot melt. The shape of the connecting portion 31 is arbitrary, but here, it is formed in a substantially rectangular shape elongated in the vertical direction. Further, the connecting portion 31 is provided spaced apart from the upper surface of the upper wall 23 by a distance L.

1対の補強部28の各々は、連結箱の対角線P1,P2(図2参照)上に位置しており、周壁30の圧縮強度を高める作用をなす。ここでは、補強部28は、面取り状の壁であって、上下方向に細長い略長方形に形成される。この補強部28と側壁27、後壁26とがなす内角θ(図2参照)は、例えば、約135°に設定される。   Each of the pair of reinforcing portions 28 is located on the diagonal lines P1, P2 (see FIG. 2) of the connection box, and functions to increase the compressive strength of the peripheral wall 30. Here, the reinforcing portion 28 is a chamfered wall and is formed in a substantially rectangular shape elongated in the vertical direction. An internal angle θ (see FIG. 2) formed by the reinforcing portion 28, the side wall 27, and the rear wall 26 is set to about 135 °, for example.

周壁30は、前壁25、後壁26、1対の側壁27および1対の補強部28によって、水平断面が略六角形に形成される。   The peripheral wall 30 is formed in a substantially hexagonal horizontal cross section by the front wall 25, the rear wall 26, the pair of side walls 27 and the pair of reinforcing portions 28.

次に、包装箱20を構成する段ボールシート40を図4に基づいて説明する。
図4に示すように、段ボールシート40は、前壁25、側壁27、補強部28、後壁26、補強部28、側壁27を帯状に順次連ねたシートである。段ボールシート40は、波形の中芯41と、中芯41の表裏両面のうち少なくとも一方の面に設けられるライナ42とによって構成される。段ボールシート40は、片面段ボールシート、両面段ボールシート、複両面段ボールシート、複々両面段ボールシートなど各種のシートから選択可能である。
Next, the cardboard sheet 40 constituting the packaging box 20 will be described with reference to FIG.
As shown in FIG. 4, the corrugated cardboard sheet 40 is a sheet in which a front wall 25, a side wall 27, a reinforcing part 28, a rear wall 26, a reinforcing part 28, and a side wall 27 are successively connected in a band shape. The corrugated board sheet 40 includes a corrugated core 41 and a liner 42 provided on at least one of the front and back surfaces of the core 41. The cardboard sheet 40 can be selected from various sheets such as a single-sided cardboard sheet, a double-sided cardboard sheet, a double-sided cardboard sheet, and a double-sided cardboard sheet.

前壁25および後壁26のそれぞれの上下両端には、第1フラップ43Fおよび第1フラップ43Rが設けられる。また、1対の側壁27のそれぞれの上下両端には、第2フラップ45が設けられる。また、前壁25の開放した側端には、継ぎしろ46が設けられる。また、側壁27の開放した側端には、接続部31が設けられる。   A first flap 43F and a first flap 43R are provided at both upper and lower ends of the front wall 25 and the rear wall 26, respectively. In addition, second flaps 45 are provided at the upper and lower ends of each of the pair of side walls 27. A joint 46 is provided at the open side end of the front wall 25. Further, a connecting portion 31 is provided at the open side end of the side wall 27.

後壁26に連なる第1フラップ43Rは、後壁26よりも大きな幅で形成される。第1フラップ43Rの基部の左右両端には、略正三角形の切り欠きが設けられる。この切り欠きを形成することによって、第1フラップ43Rの基部の左右両端には、包装箱20(図3参照)を組み立てるときに補強部28の上端あるいは下端に合わさる角度規制部47が形成される。   The first flap 43 </ b> R connected to the rear wall 26 is formed with a larger width than the rear wall 26. At both left and right ends of the base portion of the first flap 43R, substantially equilateral triangle cutouts are provided. By forming this notch, the right and left ends of the base portion of the first flap 43R are formed with angle restricting portions 47 that match the upper end or the lower end of the reinforcing portion 28 when the packaging box 20 (see FIG. 3) is assembled. .

なお、図4において、符号48a,48bで示す破線は、折り曲げ線(いわゆる罫線)であり、段ボールシート40の各部は、折り曲げ線48a,48bに沿って折り曲げられる。折り曲げ線48a,48bは、上下方向に沿った折り曲げ線48aと、水平方向に沿った折り曲げ線48bとからなる。また、段ボールシート40では、中芯41の山と谷が水平方向に並ぶように設定される。   In FIG. 4, broken lines indicated by reference numerals 48a and 48b are fold lines (so-called ruled lines), and each portion of the cardboard sheet 40 is bent along the fold lines 48a and 48b. The fold lines 48a and 48b include a fold line 48a along the vertical direction and a fold line 48b along the horizontal direction. Further, in the corrugated cardboard sheet 40, it is set so that the peaks and valleys of the core 41 are aligned in the horizontal direction.

包装箱20(図3参照)の組み立て方法について説明する。
まず、折り曲げ線48aに沿って段ボールシート40を環状に折り曲げると共に、継ぎしろ46を側壁27の裏面にホットメルトなどの接着剤で接着する。これにより、前壁25、1対の側壁27、後壁26および1対の補強部28によって、周壁30(図3参照)を形成する。また、下側の第1フラップ43Rの角度規制部47に補強部28の下端を合わせながら、下側の折り曲げ線48bに沿って下側の第1フラップ43F,43Rおよび下側の第2フラップ45を折り曲げて、底壁22(図3参照)を形成する。このとき、先に第2フラップ45を折り曲げ、後から第1フラップ43F,43Rを折り曲げるようにして、第1フラップ43F,43Rを第2フラップ45の底面にホットメルトなどの接着剤で接着する。これで、上方に開放した包装箱が得られる。
A method for assembling the packaging box 20 (see FIG. 3) will be described.
First, the corrugated cardboard sheet 40 is bent in an annular shape along the folding line 48a, and the joint 46 is bonded to the back surface of the side wall 27 with an adhesive such as hot melt. Thus, the peripheral wall 30 (see FIG. 3) is formed by the front wall 25, the pair of side walls 27, the rear wall 26, and the pair of reinforcing portions 28. Further, the lower first flaps 43F and 43R and the lower second flap 45 are aligned along the lower fold line 48b while aligning the lower end of the reinforcing portion 28 with the angle restricting portion 47 of the lower first flap 43R. Is bent to form the bottom wall 22 (see FIG. 3). At this time, the second flap 45 is bent first, and the first flaps 43F and 43R are bent later, and the first flaps 43F and 43R are adhered to the bottom surface of the second flap 45 with an adhesive such as hot melt. Thus, a packaging box opened upward is obtained.

そして、この上方に開放した包装箱の中に製品(例えば、軟包装材に充填された食品など)を装填した後、上側の第1フラップ43Rの角度規制部47に補強部28の上端を合わせながら、上側の第1フラップ43F,43Rおよび上側の第2フラップ45を上側の折り曲げ線48bに沿って折り曲げることにより、上壁23(図3参照)を形成して、包装箱の上端を閉じる。このとき、先に第2フラップ45を折り曲げ、後から第1フラップ43F,43Rを折り曲げるようにして、第1フラップ43F,43Rを第2フラップ45の上面にホットメルトなどの接着剤で接着する。これで、水平断面が略六角形の包装箱20(図3参照)の組み立てが完了する。   Then, after loading a product (for example, food filled with a soft packaging material) into the packaging box opened upward, the upper end of the reinforcing portion 28 is aligned with the angle regulating portion 47 of the upper first flap 43R. However, by folding the upper first flaps 43F and 43R and the upper second flap 45 along the upper folding line 48b, the upper wall 23 (see FIG. 3) is formed, and the upper end of the packaging box is closed. At this time, the second flap 45 is bent first, and the first flaps 43F and 43R are bent later, and the first flaps 43F and 43R are bonded to the upper surface of the second flap 45 with an adhesive such as hot melt. This completes the assembly of the packaging box 20 (see FIG. 3) having a substantially hexagonal horizontal cross section.

このようにして組み立てた包装箱20(図3参照)を2個対向させ、各々の接続部31を連結相手の側壁27にホットメルトなどの接着剤を用いて固定する。すると、水平断面が略六角形に形成された包装箱20(図3参照)を2個連結した連結箱10(図1参照)が完成する。   Two packaging boxes 20 (see FIG. 3) assembled in this manner are opposed to each other, and each connection portion 31 is fixed to the side wall 27 of the connection partner using an adhesive such as hot melt. Then, the connection box 10 (refer FIG. 1) which connected two packaging boxes 20 (refer FIG. 3) in which the horizontal cross section was formed in the substantially hexagon is completed.

この連結箱10(図1参照)は、接続部31で連結された形態で、輸送されたり保管されたりするが、開梱される際には、例えば、店員などにより切り取り線32に沿って接続部31が切断される。接続部31が切断されると、2個の包装箱20(図1参照)は、分離可能となり、それぞれ個別に開梱される。   The connecting box 10 (see FIG. 1) is transported or stored in a form connected by a connecting portion 31, but when unpacked, it is connected along a cut line 32 by a store clerk or the like, for example. The part 31 is cut. If the connection part 31 is cut | disconnected, the two packaging boxes 20 (refer FIG. 1) will become separable, and each is unpacked individually.

なお、いわゆるカットテープを周壁30(図3参照)の内面に周方向に沿って貼るなどして、包装箱20(図3参照)を上下に分割させるジッパーを設けてもよい。このようなジッパーを設けることにより、開梱時にジッパーを周方向に取り除いて上側の分割体のみを包装箱20(図3参照)から外し、下側の分割体を陳列用のトレーとして、そのまま使用することができる。   In addition, you may provide the zipper which divides | segments the packaging box 20 (refer FIG. 3) up and down by sticking a so-called cut tape on the inner surface of the surrounding wall 30 (refer FIG. 3) along the circumferential direction. By providing such a zipper, the zipper is removed in the circumferential direction during unpacking, and only the upper divided body is removed from the packaging box 20 (see FIG. 3), and the lower divided body is used as it is as a display tray. can do.

以上に述べた連結箱10の作用・効果を図5に基づいて説明する。
図5に示すように、連結箱10によれば、側壁27の前端が前壁25に略直角に連なるため、接続部31の内側には、隙間が形成されない。このため、小さい接続部31であっても、2個の包装箱20をしっかりと連結することができる。よって、資材コストを低く抑えることができる。一方、側壁27の後端に補強部28を設けることで、水平断面が略六角形の周壁30が得られるため、周壁30の圧縮強度を高めることができる。このように、実施形態においては、側壁27の前端では、補強部28を設けずに連結し易い構造を採用し、側壁27の後端では、補強部28を設けて圧縮強度を高める構造を採用した。これにより、接続部31を小さくでき、しかも高い耐圧縮性を確保できるようにした。本実施形態に係る連結箱10の圧縮強度について、水平断面が四角形のA−1式(いわゆるみかん箱タイプ)包装箱を2個連結したもの及び水平断面が八角形の包装箱を2個連結したものと対比した試験結果を表1に示す。
The operation and effect of the connection box 10 described above will be described with reference to FIG.
As shown in FIG. 5, according to the junction box 10, the front end of the side wall 27 is connected to the front wall 25 at a substantially right angle, so that no gap is formed inside the connection portion 31. For this reason, even if it is the small connection part 31, the two packaging boxes 20 can be connected firmly. Therefore, material costs can be kept low. On the other hand, by providing the reinforcing portion 28 at the rear end of the side wall 27, the peripheral wall 30 having a substantially hexagonal horizontal cross section can be obtained, so that the compressive strength of the peripheral wall 30 can be increased. As described above, in the embodiment, the front end of the side wall 27 employs a structure that facilitates connection without providing the reinforcing portion 28, and the rear end of the side wall 27 employs a structure that increases the compressive strength by providing the reinforcing portion 28. did. Thereby, the connection part 31 can be made small, and also high compression resistance was able to be ensured. Regarding the compressive strength of the junction box 10 according to the present embodiment, two A-1 type (so-called mandarin orange box type) packaging boxes having a square horizontal section and two packaging boxes having an octagonal horizontal section are coupled. Table 1 shows the test results compared with those.

Figure 2013249132
Figure 2013249132

ここで、Aは水平断面が四角形のA−1式包装箱を2個連結したものを、Bは本実施形態に係る連結箱10を、Cは水平断面が八角形の包装箱を2個連結したものである。試験に用いた段ボール箱の材質は、ライナ及び中芯がK210/S160/K210で、フルートはAFである。表1に示すように、本実施形態に係る連結箱10は、水平断面が四角形のA−1式包装箱を2個連結したものよりも約1.2倍の圧縮強度を有し、水平断面が八角形の包装箱を2個連結したものの圧縮強度と比べても遜色がない。   Here, A is a combination of two A-1 packaging boxes having a square horizontal section, B is a connection box 10 according to the present embodiment, and C is a connection of two octagonal packaging boxes with a horizontal section. It is a thing. The material of the cardboard box used for the test is K210 / S160 / K210 for the liner and the core, and AF for the flute. As shown in Table 1, the connection box 10 according to the present embodiment has a compressive strength about 1.2 times that of two connected A-1 packaging boxes having a square horizontal cross section. However, it is comparable to the compression strength of two octagonal packaging boxes connected.

また、側壁27の前端に補強部を設けない分、従来の八角形の包装箱に比べて、包装箱20に収納できる製品の個数が増える。結果、輸送効率をより一層高めることができる。   Further, since the reinforcing portion is not provided at the front end of the side wall 27, the number of products that can be stored in the packaging box 20 is increased as compared with the conventional octagonal packaging box. As a result, transportation efficiency can be further increased.

また、接続部31を上壁23の上面から下方に距離Lだけ離間して設けたので、複数の連結箱10を上下方向に積み付けて輸送あるいは保管する際、上壁23や側壁27には、白抜きの矢印で示す荷重が加わるが、接続部31には、この荷重が加わらない。   Further, since the connecting portion 31 is provided at a distance L downward from the upper surface of the upper wall 23, when the plurality of connection boxes 10 are stacked in the vertical direction for transportation or storage, the upper wall 23 and the side wall 27 are The load indicated by the white arrow is applied, but this load is not applied to the connecting portion 31.

仮に、接続部31が上壁23と同じ高さ位置にある場合、接続部31にも荷重が加わる。接続部31に荷重が加わると、本来、開梱時に切断される切り取り線32が切断されるおそれがある。   If the connection portion 31 is at the same height as the upper wall 23, a load is also applied to the connection portion 31. When a load is applied to the connecting portion 31, the tear line 32 that is originally cut when unpacking may be cut.

この点、実施形態の連結箱10では、二点鎖線で示すように荷重を受けて上壁23が沈み込んだとしても、接続部31には荷重が加わらないため、切り取り線32の切断を防ぐことができ、輸送時あるいは保管時において、連結箱10の連結強度を良好に維持することができる。   In this regard, in the connection box 10 of the embodiment, even if the upper wall 23 sinks due to a load as shown by a two-dot chain line, no load is applied to the connection portion 31, so that the cut line 32 is prevented from being cut. In addition, the connection strength of the connection box 10 can be favorably maintained during transportation or storage.

さらに、補強部28の上端および下端を角度規制部47に合わせることで、補強部28の折り曲げ角(図2に示される内角θ)を正規の角度(例えば、約135°)に規制することができる。   Further, by aligning the upper end and the lower end of the reinforcing portion 28 with the angle restricting portion 47, the bending angle (inner angle θ shown in FIG. 2) of the reinforcing portion 28 can be restricted to a regular angle (for example, about 135 °). it can.

これに対して、従来は、補強部の折り曲げ角を正規の角度にするために、型(例えば、特許文献1に記載されるマンドレルや加圧プレートなど)を用いて、段ボールシートを折り曲げるようにしていた。この場合、型の費用に加え、製造工程も増えるため、製造コストが高くなる。   On the other hand, conventionally, a corrugated cardboard sheet is folded using a mold (for example, a mandrel or a pressure plate described in Patent Document 1) in order to make the bending angle of the reinforcing portion a regular angle. It was. In this case, since the manufacturing process increases in addition to the cost of the mold, the manufacturing cost increases.

この点、実施形態の連結箱10では、補強部28の折り曲げ角θ(図2参照)を容易に正規の角度に規制できるので、補強部28を折り曲げるための専用の型および工程が不要である。これにより、製造コストを低く抑えることができる。   In this regard, in the connection box 10 of the embodiment, the bending angle θ (see FIG. 2) of the reinforcing portion 28 can be easily regulated to a regular angle, so that a dedicated mold and process for bending the reinforcing portion 28 are not necessary. . Thereby, manufacturing cost can be suppressed low.

したがって、本実施形態によれば、資材コストおよび製造コストを低く抑えることができる共に圧縮強度を高めることができ、しかも高い輸送効率が得られる連結箱10を提供することができる。   Therefore, according to the present embodiment, it is possible to provide the junction box 10 that can keep the material cost and the manufacturing cost low and can increase the compressive strength and obtain high transport efficiency.
