特許法第３０条第２項適用平成３０年９月４日～同年同月７日，第８６回東京インターナショナル・ギフト・ショー秋２０１８，東京ビッグサイト（東京都江東区有明３－１１－１）にて本橋敏明氏が発明した箱体を公開Application of Article 30, Paragraph 2 of the Patent Act From September 4, 2018 to September 7, 2018, at the 86th Tokyo International Gift Show Autumn 2018, Tokyo Big Sight (3-11-1 Ariake, Koto-ku, Tokyo) The box body invented by Toshiaki Motohashi is released

本発明は組立てが可能な包装用の箱体に関し、美粧性を確保しながら簡便迅速に組立てることができる箱体に関する。 TECHNICAL FIELD The present invention relates to a packaging box body that can be assembled, and more particularly to a box body that can be assembled simply and quickly while ensuring aesthetics.

一枚の平面状の厚紙、プラスチック等のブランク（板材）を折り曲げ、接着剤や紐などで固定して形状を維持する箱体は、一般に、底板部と、底板部の周囲に立てられた側板部と、この側板部に繋がり、側板部で作る開口部を閉鎖する開閉可能な蓋板部などから構成される。このような箱体は意匠性の高い包み紙などを用いるとともにその内部にギフトやお菓子などを収納して、季節感を演出したり特別なイベントなどを訴求したりする際に用いられることが多い。 A box body, which is made by folding a sheet of flat cardboard or plastic blank (plate material) and fixing it with adhesive or string to maintain its shape, generally consists of a bottom plate and side plates erected around the bottom plate. and an openable and closable lid plate portion connected to the side plate portion and closing the opening formed by the side plate portion. Such boxes are often used to create a sense of the season or promote special events by using highly designed wrapping paper and storing gifts and sweets inside. many.

組立ての際に接着剤を使って形状を維持する箱体は、箱体の展開図に従って折線をプレスして切り抜いた平面状のブランクを、折線に沿って折り曲げた後にのりしろを接着して立体である箱体に組立てられる。 The box body, which uses adhesive to maintain its shape during assembly, is made into a three-dimensional shape by pressing the folding lines according to the developed view of the box body, cutting out the flat blanks, folding them along the folding lines, and then gluing the glue margins. Assembled in a box.

しかしながら、組立てに接着材を用いる場合は、接着の工程が必要となり、箱体を包装に用いる販売店などの現場で簡便迅速に組立てることが困難である。 However, when an adhesive is used for assembly, an adhesion step is required, making it difficult to simply and quickly assemble the box at a shop or the like where the box is used for packaging.

このため、用途によっては、接着ではなく各側板部に紐を通して巻き回して箱体の形状を維持する場合がある。このようにすると、箱体の組立てが現場で簡便迅速にできるとともに、輸送や保管の際は平状態（フラットなブランクの状態）として省スペースを図りながら、包装に用いる際はその内部に物品が収納可能な箱体に組立てることができるため、便利である。このような紐を巻き回して箱体とする技術は、巾着に用いられているものがある（特許文献１）。 For this reason, depending on the application, the shape of the box may be maintained by passing a string through each side plate portion and winding the string instead of bonding. In this way, the box body can be assembled easily and quickly on site, and the box body can be placed in a flat state (flat blank state) during transportation and storage to save space, and when used for packaging, an article can be placed inside the box body. It is convenient because it can be assembled into a box that can be stored. A technique of winding such a string to form a box is used for a purse (Patent Document 1).

しかしながら、この技術は、いわゆる巾着締めであるため、蓋板部のない箱体について側板部に通した紐を締めることによって、各側板部の中央部の折り曲げ個所を突き合わせて側板部上部の開口部を閉鎖する（特許文献１第１図）。このため、蓋板部を備えた直方体形状の箱体を形成することはできなかった。 However, since this technique is a so-called drawstring tightening, by tightening the string passed through the side plate of the box without the cover plate, the bent points at the center of the side plates are brought together and the opening at the top of the side plate is tightened. is closed (Fig. 1 of Patent Document 1). For this reason, it was not possible to form a rectangular parallelepiped box having a cover plate.

また、巾着締め以外では、箱蓋に関するものがあり、この技術は、固定紐を通すための袖（紐の固定装置）を箱蓋の側板部に備え、この袖に通した固定紐を組立ての際に絞ることにより箱蓋を形成する（特許文献２）。 In addition to drawstring tightening, there is also a technique related to box lids, and this technology is provided with a sleeve (string fixing device) for passing a fixing string on the side plate of the box lid, and the fixing string passed through the sleeve is assembled. A box lid is formed by squeezing it (Patent Document 2).

しかしながら、このような袖を箱体の側板部に備えるとすると側板部の製造の際の加工の手間が増加する。のみならず、平面状のブランクから箱体を組立てる場合は、ブランクの製造工程が複雑になるため採用が困難である。
また、組立ての際に固定紐を袖に通す場合、袖の長さや紐と袖の寸法関係などによっては紐を通すことが困難な場合もあるため、簡便迅速な組立てができない恐れがある。さらに、蓋で箱体を閉鎖する場合、側板部に設けた袖と干渉して閉鎖が困難になることがある。加えて、袖が存在することにより、箱体の意匠における美粧性が劣化する場合がある。
このため、ブランクから箱体を組立てる場合は、袖を採用することが困難である。 However, if such a sleeve is provided on the side plate portion of the box, the time and effort required for manufacturing the side plate portion increases. Moreover, when assembling a box from planar blanks, the manufacturing process of the blanks becomes complicated, which makes it difficult to adopt.
In addition, when the fixing string is passed through the sleeve during assembly, it may be difficult to pass the string through the sleeve depending on the length of the sleeve and the dimensional relationship between the string and the sleeve, which may hinder simple and quick assembly. Furthermore, when the lid is used to close the box, it may interfere with the sleeves provided on the side plates, making closing difficult. In addition, the presence of the sleeves may deteriorate the aesthetics of the design of the box.
For this reason, it is difficult to employ sleeves when assembling a box from a blank.

以上の考察から、接着剤を用いずに固定紐によって形状を維持する箱体を検討し、各側板部に貫通孔を複数設け、この貫通孔に順次紐を通して締め、簡便迅速に各側板部を固定することを考えた。この場合、試作をしてみると、紐の張力により側板部が箱体の内側に倒れる現象が生じることがわかった。
そこで、固定紐に張力がかかった場合でも側板部の倒れを防止して直立を維持するための検討を進め、側板部に羽根を設けるとともにこれらに設けた固定紐が通る貫通孔の位置についての知見が得られ、本発明に至った。 Based on the above considerations, we investigated a box body that maintains its shape by fixing strings without using adhesives. thought of fixing it. In this case, when a prototype was made, it was found that the tension of the string causes the side plate portion to fall inside the box.
Therefore, we investigated ways to prevent the side plates from collapsing and maintain the upright position even when tension is applied to the fixing straps. This finding led to the present invention.

Side plate portion through-holes 21 are formed in corner portions on both sides of the side plate portion 20 to which the cover plate portion 30 is connected. The side plate portion through-hole 21 is a hole through which the fixing string S is passed in order to maintain the shape when the box A is assembled from the blank b.
A side plate portion 23 connected to the opposite side of the side plate portion 20 with respect to the bottom plate portion 10 has a rectangular shape like the side plate portion 20 . Similarly to the side plate portion 20 , the side plate portion 23 also has side plate portion through holes 21 at corner portions on both sides of the side plate portion 23 , which are symmetrical to the side plate portion 20 with the bottom plate portion 10 interposed therebetween. The side plate portion through-hole 21 is a hole through which the fixing string S is passed in order to maintain the shape when the box A is assembled from the blank b.

（側板部）
側板部２０が接続する底板部１０の両隣の辺にそれぞれ接続されている側板部２５は、底板部２０、２３と同様に矩形形状である。底板部１０に関し側板部２５の側板部１０の接続部１６と反対側の辺に近いコーナー部に、側板部貫通孔２１がそれぞれ開けられている。
なお、後述のように側板部２５は、一対の羽根５０、５０が左右の側端から伸びて形成されている（図２）。 (Side plate)
The side plate portions 25 connected to the sides adjacent to the bottom plate portion 10 to which the side plate portions 20 are connected have a rectangular shape like the bottom plate portions 20 and 23 . Side plate portion through-holes 21 are formed in the corner portions of the side plate portions 25 near the sides of the side plate portions 10 opposite to the connection portion 16 with respect to the bottom plate portion 10 .
As will be described later, the side plate portion 25 is formed with a pair of blades 50 extending from left and right side ends (FIG. 2).

（貫通孔）
側板部貫通孔２１は、側板部２０、２３、２５、２５に開けられている。ブランクｂから箱体が組立てられる際に、形状を維持するために固定紐Ｓが通される孔である（図３参照）。
側板部２３に開けられた側板部貫通孔２１は、完成した箱体Ａに関してその高さ方向の位置は前述のように同一である。また、箱体Ａのコーナー部からの水平方向の位置も同一である。このようにすると、対称性が高くなり固定の強度が高くなる。また、意匠性も整った印象を与えることができる。
ただし、側板部貫通孔２１の位置は、各側板部２０、２３、２５、２５で同一でなくとも差し支えない。この場合は、固定紐Ｓを側板部貫通孔２１を通して、各側板部２０、２３、２５、２５の外側を巻きまわす際に、箱体Ａのコーナー部では側板部貫通孔２１からその内部を通すことができれば、固定紐を締めることにより、側板部２０、２１、２１、２５を直立させて箱体Ａの形状を維持することができる。
なお、側板部２１を箱体Ａの水平方向についてコーナー部に近づければ箱体Ａの内部に物品を収納するスペースは大きくすることができ、遠ざければその反対に小さくなる。 (through hole)
Side plate portion through holes 21 are formed in side plate portions 20 , 23 , 25 , and 25 . It is a hole through which a fixing string S is passed in order to maintain the shape when the box is assembled from the blank b (see FIG. 3).
The side plate portion through-holes 21 formed in the side plate portions 23 have the same position in the height direction with respect to the completed box A as described above. The horizontal position from the corner of the box A is also the same. In this way, the symmetry is enhanced and the fixing strength is enhanced. In addition, it is possible to give a well-designed impression.
However, the positions of the side plate portion through-holes 21 do not have to be the same among the side plate portions 20 , 23 , 25 and 25 . In this case, when the fixing string S is passed through the side plate portion through-hole 21 and wound around the outside of each of the side plate portions 20, 23, 25, 25, the inside of the box A is passed through the side plate portion through-hole 21 at the corner portion. If possible, by tightening the fixing string, the side plate portions 20, 21, 21, 25 can be erected and the shape of the box A can be maintained.
If the side plate portion 21 is brought closer to the corner portion in the horizontal direction of the box A, the space for storing the article inside the box A can be increased, and if it is moved away, it becomes smaller.

（羽根）
側板部２５の両側端からそれぞれ羽根５０が折線１６を介し伸びて形成されている。羽根５０は、箱体Ａが組立てられたときに箱板Ａのコーナー部で側板部２０に重ねられて二重となるため、箱体Ａの緊密性が保ちやすい。箱体Ａのコーナー部を接着せずに突合せにすると、隙間ができやすく箱体Ａの緊密性が低下する。羽根５０を箱体Ａの内部に入れることにより、箱体Ａのコーナー部で羽根５０と隣の側板部２０が面と面で重なるため、固定紐Ｓで固定する場合でも箱体Ａの緊密性が高くすることができる。。また、コーナー部の強度も高くすることができる利点がある。
加えて、箱体Ａの内部に入った羽根５０は隣の側板部２０に対し、面と面で重なるため、隣の側板部２０が内側に倒れようとする際に側板部２５が羽根５０を介してその力を受けることができるため、側板部２０の倒れ防止の機能がある。
なお、後述するように、羽根５０の羽根貫通孔５１を固定紐Ｓが通過するため、側板部２０の倒れ防止機能のみならず、側板部２５の倒れ防止機能も本例の羽根５０は有している。 (feather)
Blades 50 are formed extending from both side ends of the side plate portion 25 via the folding lines 16 . When the box A is assembled, the blades 50 are overlapped on the side plate portions 20 at the corners of the box plate A to form a double layer. If the corners of the box A are butted without bonding, gaps are likely to occur and the tightness of the box A is reduced. By putting the blades 50 inside the box A, the blades 50 and the adjacent side plate portions 20 are overlapped face-to-face at the corners of the box A, so that the tightness of the box A is maintained even when fixed with the fixing string S. can be raised. . Moreover, there is an advantage that the strength of the corner portion can be increased.
In addition, since the blades 50 that have entered the inside of the box A overlap the adjacent side plate portions 20 face-to-face, the side plate portions 25 push the blades 50 when the adjacent side plate portions 20 are about to fall inward. Since the force can be received through the side plate portion 20, it has a function of preventing the side plate portion 20 from falling.
As will be described later, since the fixing string S passes through the blade through hole 51 of the blade 50, the blade 50 of this example has not only the function of preventing the side plate portion 20 from falling, but also the function of preventing the side plate portion 25 from falling. ing.

（蓋）
蓋３０は、底板部１０が接続されている側板部２０の反対側の辺に折線１６を介して設けられている。蓋３０は、底板部１０と同じ大きさで、箱体Ａが組立てられたときに底板部１０と相対する位置になる。
押さえ板部４０は、側板部２０が接続されている蓋３０の反対側の辺に、折線１６を介して設けられている。押さえ板部４０は、箱体Ａが組立てられたときにその内部に物品を収納して蓋３０を閉めて閉空間を作ることができる。
押さえ板部４０は、蓋３０を閉めるために、固定紐Ｓが蓋と係止するための切込み４１を有する。切込み４１の代わりに貫通孔を有してもよい。 (lid)
The lid 30 is provided on the opposite side of the side plate portion 20 to which the bottom plate portion 10 is connected via the folding line 16 . The lid 30 has the same size as the bottom plate portion 10 and is positioned to face the bottom plate portion 10 when the box A is assembled.
The pressing plate portion 40 is provided on the opposite side of the lid 30 to which the side plate portion 20 is connected via the folding line 16 . When the box body A is assembled, the pressing plate part 40 can store articles therein and close the lid 30 to create a closed space.
The pressing plate portion 40 has a notch 41 for locking the fixing string S with the lid in order to close the lid 30 . A through hole may be provided instead of the cut 41 .

（箱体Ａの組立て方法）
ブランクｂは、各板１０、２０、２３，２５、３０、４０、５０を画する折線１６を折り曲げて組立てることができる。箱体Ａの完成時は、立体となり、直方体形状を有する。なお、立方体形状とすることも差し支えない。このようなブランクｂから固定紐Ｓを用いて形状を維持する完成した箱体Ａとするのは、以下のような手順で行う。 (How to assemble box A)
The blank b can be assembled by folding fold lines 16 delimiting each plate 10,20,23,25,30,40,50. When the box A is completed, it becomes three-dimensional and has a rectangular parallelepiped shape. It should be noted that a cubic shape may also be used. A completed box A whose shape is maintained by using the fixing string S from such a blank b is performed by the following procedure.

まず、図４に示すように、ブランクｂの側板部２０、２３、２５、２５の側板部貫通孔２１及び羽根５０の羽根貫通孔５１に固定紐Ｓを通す。固定紐Ｓは基本的に側板部２０，２３、２５の箱体Ａの外部側を巻き回すが、羽根５０がある箱体Ａのコーナー部においては、側板部貫通孔２１から箱体Ａの内部に入り羽根５０の羽根貫通孔５１を経由して隣の側板部２０、２３の側板部貫通孔２１を経由して箱体Ａの外部に出るようにする。このようにして箱体Ａの周囲を巻き回し、蓋板部４０が被さる側板部２３の側板部貫通孔２１、２１から固定紐Ｓの両端部がでてくるように固定紐Ｓをセットする。 First, as shown in FIG. 4, the fixing string S is passed through the side plate portion through holes 21 of the side plate portions 20, 23, 25, 25 of the blank b and the blade through holes 51 of the blades 50. As shown in FIG. The fixing string S basically winds around the side plate portions 20, 23, and 25 on the outer side of the box A, but at the corner portion of the box A where the blades 50 are located, the fixing string S is wound inside the box A from the side plate portion through-hole 21. First, through the blade through hole 51 of the inlet blade 50, through the side plate portion through holes 21 of the adjacent side plate portions 20, 23, it is made to come out to the outside of the box A. In this way, the fixing string S is wound around the box A and set so that both ends of the fixing string S come out from the side plate portion through holes 21, 21 of the side plate portion 23 covered by the cover plate portion 40.例文帳に追加

次に、図５に示すように、各側板部２０、２３、２５、２５を底板部１０の折線１６から直角に立ち上がるように曲げるとともに、各羽根５０は箱体Ａの内部に入るように側板部２５の折線１６を折りたたむ。
この状態にした後に、固定紐Ｓを引くと、各側板部２０、２３、２５、２５は、底板部１０の折線１６から直角に立ち上がる。そして、蓋板部３０を側板部２５の折線１６から折り曲げるとともに押さえ板部４０を蓋板部３０の折線１６から折り曲げると、蓋３０を閉じることができ、その内部に物品が収納可能な箱体Ａが形成される。
さらに、図４に示すように、側板部２３の側板部貫通孔２１を通って箱体Ａの外側に伸びた固定紐Ｓの両端部を押さえ部４０の切込み４１の外側を通るように巻き回して結ぶと、蓋３０が固定されて、箱体Ａが完成する。 Next, as shown in FIG. 5, each side plate portion 20, 23, 25, 25 is bent so as to stand up at right angles from the folding line 16 of the bottom plate portion 10, and each blade 50 is bent into the inside of the box A. The fold line 16 of the portion 25 is folded.
When the fixing string S is pulled in this state, the side plate portions 20 , 23 , 25 , 25 stand up at a right angle from the folding line 16 of the bottom plate portion 10 . When the lid plate portion 30 is folded along the folding line 16 of the side plate portion 25 and the holding plate portion 40 is folded along the folding line 16 of the lid plate portion 30, the lid 30 can be closed and an article can be stored therein. A is formed.
Further, as shown in FIG. 4, both ends of the fixing string S extending outside the box A through the side plate portion through-holes 21 of the side plate portion 23 are wound so as to pass outside the notch 41 of the pressing portion 40. By tying it together, the lid 30 is fixed and the box body A is completed.

（側板部の直立を維持する仕組み）
このとき、各側板部２０、２３、２５、２５は底板部１０の折線１６から直角に立ち上がる状態を維持するのであるが、その仕組みを説明する。
図６は、箱体Ａ´の側板部２５´が倒れる説明図である。箱体Ａ´において固定紐Ｓ´が箱体Ａ´に水平に巻き回された場合の固定紐Ｓ´を含む水平断面の箱体Ａ´のコーナー部を模式的に示している。なお、この場合、各板について、説明の便宜のために、本発明の説明で用いた参照番号に「´」をつけて、以下図面とともに説明する。
図６に示すように、箱体Ａ´を完成させるために固定紐Ｓ´を巻きまわして締めると、固定紐Ｓ´にはその軸線方向に張力Ｔが働く。この張力Ｔは、以下に示すように、側板部２５´を箱体Ａ´の内部（内側）に引き倒す力Ｆを発生させる。
固定紐Ｓ´は、側板部２５´に対し、箱体Ａ´の外側側面、すなわち側板部２５´の外側側面を通り、箱体Ａ´のコーナー部では箱体Ａ´の内部（内側）に入り、コーナー部で重ねられた羽根５０´と側板部２０´のそれぞれの羽根貫通孔５１´、２１´を貫いて通り、側板部２０´の外側側面（すなわち、箱体Ａ´の外側側面）に出たあと側板部２０´に沿って巻き回される。このため、固定紐Ｓ´に張力Ｔが働くと固定紐Ｓ´は直線状態になろうとして側板部２５´を箱体Ａ´の内側に倒そうとする力Ｆが働く。この結果、図６に示すように側板部２５´は箱体Ａ´の内側に倒れることになる。この場合の倒れ量をＬとする。 (Mechanism to keep the side plate upright)
At this time, each of the side plate portions 20, 23, 25, 25 maintains a state of rising at right angles from the folding line 16 of the bottom plate portion 10. The mechanism will be explained.
FIG. 6 is an explanatory diagram of the state in which the side plate portion 25' of the box A' falls down. The corner portion of the horizontal section of the box A' including the fixing string S' when the fixing string S' is horizontally wound around the box A' is schematically shown. In this case, for convenience of explanation, each plate will be explained with reference to the drawings by adding "'" to the reference numbers used in the explanation of the present invention.
As shown in FIG. 6, when the fixing string S' is wound and tightened to complete the box A', tension T acts on the fixing string S' in its axial direction. This tension T generates a force F that pulls down the side plate portion 25' toward the inside (inner side) of the box A' as described below.
The fixing string S' passes through the outer side surface of the box A' with respect to the side plate portion 25', that is, the outer side surface of the side plate portion 25', and extends inside (inside) the box A' at the corner portion of the box A'. It passes through the blade through-holes 51' and 21' of the blade 50' and the side plate portion 20' overlapped at the corner portion, and passes through the outer side surface of the side plate portion 20' (that is, the outer side surface of the box A'). After coming out, it is wound along the side plate portion 20'. Therefore, when the tension T acts on the fixing string S', the fixing string S' tries to straighten, and a force F acts to push the side plate portion 25' toward the inside of the box A'. As a result, the side plate portion 25' falls inside the box A' as shown in FIG. Let L be the tilt amount in this case.

この倒れ方を観察すると、そもそも、固定紐Ｓ´は、各側板部を起立させて箱体Ａ´の形状を維持するために箱体Ａ´の外部を巻き回して締めるものである。しかし、箱体Ａ´の四隅のコーナー部では、固定紐Ｓ´は側板部貫通孔２１、５１を通って箱体Ａ´の内部を通る構造としている。これは、固定紐Ｓ´が箱体Ａ´から外れにくくして一定の位置を保つとともに、貫通孔を通す作業が簡単にできるため、箱体Ａ´を簡便迅速に完成させることができるようにするためである。
このような構造であるため、常に側板部２０´、２３´、２５´、２５´は、箱体Ａ´の内側に倒れようとする力Ｆが働く。このうち、側板部２０´に対しては、隣の側板部２５´の羽根５０´が箱体Ａ´のコーナー部でその内部に直角に曲がって側板部２０´に沿って重なっているため、羽根５０´を介して側板部２０´、２３´が箱体Ａ´の内部（内側）に倒れようとする力Ｆを受け止めることができる。このようにすると、側板部２０´、２３´が箱体Ａ´の内側に倒れることを防止できる。 Observing this way of falling down, the fixing string S' originally winds and tightens the outside of the box A' in order to raise each side plate portion and maintain the shape of the box A'. However, at the four corners of the box A', the fixing string S' passes through the side plate through-holes 21 and 51 to pass through the inside of the box A'. This makes it difficult for the fixing string S' to come off from the box A' and keeps it in a fixed position, and also makes it easier to pass through the through-hole, so that the box A' can be completed simply and quickly. It is for
Due to such a structure, the side plate portions 20', 23', 25', 25' are always subjected to a force F that causes them to fall toward the inside of the box A'. Of these, with respect to the side plate portion 20', the blades 50' of the adjacent side plate portion 25' are bent at a right angle to the inside at the corner portion of the box A' and are overlapped along the side plate portion 20'. The side plate portions 20' and 23' can receive the force F that causes the side plate portions 20' and 23' to fall inside (inside) the box A' via the blades 50'. By doing so, it is possible to prevent the side plate portions 20' and 23' from falling inside the box A'.

しかし、側板部２５´に対しては、側板部２５´が内側に倒れようとする力Ｆを受け止めることができない。このため、羽根５０´を介して底板部１０´で受け止める構造も考えられるが、このようにすると羽根５０´を直立させた際に羽根５０´の下端部と底板部１０´がちょうど接するようにする必要があり、製造時の寸法ばらつきを考えると、きわめて精密に組立てる必要が生じるため、実現が困難である。
また、側板部２０´と羽根５０´のそれぞれの側板部貫通孔２１´と羽根貫通孔５１´の位置関係については、側板部２０´を直立させて箱体Ａ´を完成させたときにちょうど重なる位置に設けるのが自然であるが、そうすると箱体Ａ´のコーナー部を斜めにわたる固定紐Ｓ´に前述のように張力Ｔが働くと、結果として側板部２５´が箱体Ａ´の内部に倒れ量Ｌだけ倒れることが分かった。 However, the side plate portion 25' cannot receive the force F that causes the side plate portion 25' to fall inward. For this reason, it is conceivable to adopt a structure in which the bottom plate portion 10' receives the blades 50' via the blades 50', but in this case, when the blades 50' are erected, the lower end portion of the blades 50' and the bottom plate portion 10' are just in contact with each other. Considering the dimensional variation during manufacturing, it is necessary to assemble them very precisely, which is difficult to realize.
Further, regarding the positional relationship between the side plate portion through-holes 21' and the blade through-holes 51' of the side plate portion 20' and the blades 50', when the side plate portion 20' is erected to complete the box body A', It is natural to provide them at overlapping positions, but if this is the case, when the tension T acts on the fixing string S' diagonally extending over the corners of the box A' as described above, the side plate portions 25' will eventually move inside the box A'. It turned out that it falls down only by the amount L of falling down.

そこで、本例では、図８に示すように、最初から羽根５０の羽根貫通孔５１を側板部２０の側板部貫通孔２１に対し、箱体Ａの水平方向内側にコーナー部と反対側に偏心して配置することとした。なお、図８は、側板部２０の側板部貫通孔２１について説明しているが、側板部２３の側板部貫通孔２１でも同様である。
図８は、その状態の一例を示したものであり、（ａ）は、側板部２０の側板部貫通孔２１と羽根５０の羽根貫通孔５１の位置関係を示したもので、側板部２０に対し側板部２５の羽根５０が重ねられた状態のものを箱体Ａの内側から見た状態を模式的に表している。図に示されるように、羽根貫通孔５１は側板部貫通孔２１に対して箱体Ａの水平方向（紙面の左右方向）に対してコーナー部と反対の側板部２１の中央側に偏心して配置されている。 Therefore, in this example, as shown in FIG. 8, the blade through-holes 51 of the blades 50 are biased from the beginning with respect to the side plate portion through-holes 21 of the side plate portion 20 toward the inner side in the horizontal direction of the box A to the side opposite to the corner portion. I decided to place it carefully. Although FIG. 8 illustrates the side plate portion through-hole 21 of the side plate portion 20 , the same applies to the side plate portion through-hole 21 of the side plate portion 23 .
FIG. 8 shows an example of such a state, and (a) shows the positional relationship between the side plate portion through hole 21 of the side plate portion 20 and the blade through hole 51 of the blade 50. On the other hand, a state in which the blades 50 of the side plate portion 25 are superimposed is schematically shown when viewed from the inside of the box A. As shown in FIG. As shown in the figure, the blade through-holes 51 are arranged eccentrically with respect to the side plate through-holes 21 on the center side of the side plate portion 21 opposite to the corner portion with respect to the horizontal direction (horizontal direction of the paper surface) of the box A. It is

このように偏心して配置したものを、先述の図６と同様にして固定紐Ｓを通した状態を示したものが図７である。図７に示すように、固定紐Ｓに張力Ｔが働いた場合に、図６同様に、側板部２５は箱体Ａの内側に倒れようとするが、羽根５０の羽根貫通孔５１が箱体Ａの内側に向けて水平方向にシフトをしている。このシフト量をＭとすると、図６で示すように倒れ量Ｌに相当する分だけシフトさせればよい。このようにすると、固定紐Ｓは、側板部２０の側板部貫通孔２１の周縁部Ｃｆと羽根５０の羽根貫通孔５１の周縁部Ｃｓとに接することにより支えられて、側板部２５の内側の倒れようとする力Ｆに抗することができる。
倒れ量Ｌは、側板部貫通孔２１、５１の形状と大きさ、固定紐Ｓの太さ、固定紐の張力、側板部の剛性などを主要なファクターとして決まる量である。 FIG. 7 shows a state in which the eccentric arrangement is passed through the fixing string S in the same manner as in FIG. 6 described above. As shown in FIG. 7, when a tension T is applied to the fixing string S, the side plate portion 25 tends to fall inside the box A as in FIG. There is a horizontal shift towards the inside of A. Assuming that the amount of shift is M, the shift may be made by an amount corresponding to the amount of tilt L as shown in FIG. In this way, the fixing string S is supported by being in contact with the peripheral edge portion Cf of the side plate portion through-hole 21 of the side plate portion 20 and the peripheral edge portion Cs of the blade through-hole 51 of the blade 50, and is supported inside the side plate portion 25. It can resist the force F that tries to fall down.
The leaning amount L is determined mainly by factors such as the shape and size of the side plate portion through-holes 21 and 51, the thickness of the fixing string S, the tension of the fixing string, the rigidity of the side plate portion, and the like.

図８（ｂ）は、羽根貫通孔５１のシフト量Ｍの計算の目安を説明するものである。側板部貫通孔２１と羽根貫通孔５１はいずれも貫通孔の断面が直径ｒの円形で、それぞれの中心をＯｆ、Ｏｓとしている。また、固定紐Ｓは、側板部貫通孔２１と羽根貫通孔５１を通るためには、固定紐Ｓの断面の直径ｇは側板部貫通孔２１、５１のそれぞれの直径ｒより小さくする必要がある。そうすると、両貫通孔の距離ｄは、ｄ＝２ｒ－ｇで示され、この距離ｄをシフト量Ｍとすることもできる。
さらに、側板部貫通孔２１と羽根貫通孔５１の間に固定紐Ｓがちょうど挟まった場合（ｇ＝ｒ、不図示）は、側板部２０、２３の側板部貫通孔２１の周縁部Ｃｆと側板部２５の羽根貫通孔５１の周縁部Ｃｓに接するとともにそれぞれの貫通孔２１、５１の内壁の周面が固定紐Ｓを挟むこととなり、固定紐Ｓと貫通孔２１、５１の間の遊びが少なくなるので、さらに側板部２５の倒れを防止することができる。 FIG. 8(b) explains a guideline for calculating the shift amount M of the blade through hole 51. FIG. Both the side plate portion through-hole 21 and the blade through-hole 51 have a circular cross-section with a diameter r, with the centers of Of and Os, respectively. In addition, in order for the fixing string S to pass through the side plate portion through-hole 21 and the blade through-hole 51, the cross-sectional diameter g of the fixing string S needs to be smaller than the diameter r of each of the side plate portion through-holes 21 and 51. . Then, the distance d between the two through-holes is given by d=2r−g, and this distance d can be used as the shift amount M.
Furthermore, when the fixing string S is just sandwiched between the side plate portion through hole 21 and the blade through hole 51 (g=r, not shown), the peripheral edge portion Cf of the side plate portion through hole 21 of the side plate portions 20 and 23 and the side plate portion The peripheral surfaces of the inner walls of the through-holes 21 and 51 are in contact with the peripheral edge portion Cs of the blade through-hole 51 of the portion 25, and the fixing string S is sandwiched therebetween, so that the play between the fixing string S and the through-holes 21 and 51 is small. Therefore, it is possible to further prevent the side plate portion 25 from collapsing.
