Description

【０００１】
【発明の属する技術分野】
本発明は、容器内に収納空間を形成可能な保持板部を形成したプラスチックシート製の組立容器に関する。
【０００２】
【従来の技術】
透明性が良好で剛性もあるアモルファスポリエチレンテレフタレート（Ａ―ＰＥＴ）などのプラスチックシートに折り曲げ罫線を設けてなる組立容器が造られている。従来のこの種の容器は、例えば特許文献１の如く、折り曲げ罫線を介して正背面板部，左右側面板部を連設し、正面乃至背面板部から上下に折り曲げ罫線を介して蓋片を連設し、いずれかの板部乃至片の端から罫線を介して容器内に配置することになるフラップを延設し、このフラップは容器を組立て立体化した後に、容器内周面すなわち四側面板部の各内面に密接するように容器内に圧入させて被収納物を保持するようにした構成のものであった。
【０００３】
【特許文献１】
特開２００１−１３９０１９号公報
【０００４】
【発明が解決しようとする課題】
上記のような構成であると、容器を組立て立体化させた後、フラップを折曲げる作業、折曲げたものに被収納物を保持させながらこれを容器内に圧入して固定する作業などが必要であり、容器の製造、組立工程と、被収納物を収納する包装化工程とを分離し難く、容器製造乃至流通工程を十分に合理化し難い問題があった。
【０００５】
上記の改善として、糊代片を接着して容器を組立てる工程において、フラップを容器内に折込んで内装させて、組立容器を偏平二つ折り状態に折畳んで運搬、保管できるようにし、被収納物包装時に容器を立体化させることが可能な容器構成とすることができれば好ましい。この場合、内装したフラップは立体化作業に支障を与えないように構成されなければならず、特に、容器内に収納空間を形成させるフラップが容器の折畳み乃至立体化に円滑に連動し得ることが望まれる。このようなものとして、図１２、１３に示す如き構成を考えることができる。これは、折曲して容器を組立て可能な側面板部２１の一側縁にフラップ２２を折曲げ罫線２３を介して連設し、フラップ２２を容器内に折込んだ上で糊代片２４を接着して組立容器を形成するもので、この容器を立体化するときに容器内においてフラップ２２がＶ字形となり、Ｖ字凹部に被収納物２５の収納空間が形成されるようにするものである。
【０００６】
しかしながら、この構成の場合、組立容器を罫線２３と対角端の罫線の２箇所を折畳んだ形で偏平二つ折り状に折畳んだときに、フラップ２２がサンドイッチ状態で二つ折れ容器内に挟まるが、フラップが二つ折れ幅よりも長いとフラップが平坦に延びないために容器の偏平な折畳みができず、運搬、保管に支障を来たし、短いと、図７の如く立体化した容器内でＶ字フラップががたつくか、被収納物ががたついてしまい、商品価値を下げてしまう問題が起こり、長さが一致するとフラップ端縁が二つ折り部分の内側に食い込んでしまう結果、フラップがＶ字に形成され難いなどの問題が起こるおそれがあり、寸法制約が強すぎる問題がある。
本発明は、上記問題点を解決し、フラップすなわち被収納物用保持板部を内装させた状態で、容器を偏平二つ折り状態に折畳んで運搬、保管を便利にでき、被収納物の包装時には容器を立体化するだけで被収納物を安定的に収納することができるプラスチックシート組立容器を提供せんとするものである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、本発明は、直方体箱状の四側面を構成する正面板部、右側面板部、背面板部及び左側面板部と、前記箱状の蓋面を構成する蓋片）とがそれぞれ罫線を介して連設されているとともに、前記正面板部の側縁に糊代片が罫線を介して連設された輪郭にプラスチックシートを打ち抜き、このプラスチックシートの前記各面板部及び各片を各罫線で折り曲げ、前記糊代片を左側面板部の外側縁に固着させて箱状に組み立てられるプラスチックシート組立容器において、前記左側面板部の側端部から罫線を介して容器内に折込み可能な保持板部が、被収納物の収納空間を形成可能な長さを有して延設され、この保持板部の中間部に、背面板部内面に当接可能な支持片が形成されているとともに、前記正面板部に収納空間内に収納された被収納物に当接可能な凹凸部が形成された構成を有することを特徴とする。
上記保持板部は、中間部を折曲乃至湾曲して収納空間を形成した状態において、保持板部を連設した左側面板部とこれに対面する右側面板部の両側面板部間にほぼ渡る長さを有し、かつ、平板状に伸ばした状態において、偏平に折畳んだ正面板部と右側面板の両端部間の長さよりは短い長さを有して形成するのが好ましい。
【０００８】
本発明は、上記保持板部の少なくとも上下いずれかに収納空間内に折曲張出し可能な調整板部を形成してプラスチックシート組立容器を構成したことも特徴とする。
また、保持板部の中央に罫線が形成され、箱状に組み立てられた容器内に保持板部が、正面板部側を幅広開放部とした断面Ｖ字状に折れ曲がって納まるように構成することができる。
さらに、少なくとも保持板部には箔押しその他の印刷模様を形成し、装飾効果を高めることができる。
【０００９】
【発明の実施の形態】
以下、本発明の一例としての実施の形態を図面によって説明する。
図１〜３は本発明に係るプラスチックシートの一実施形態図、図４、５は支持片、保持板部の変形例図、図６〜１０は本発明のさらに異なる三例の実施形態図、図１１、１２は本発明の対比図である。
【００１０】
図１は、直方体箱状の組立容器を形成するためのプラスチックシートであり、Ａ−ＰＥＴ、ポリプロピレン、ポリエチレン、ポリカーボネート、生分解性樹脂例えばポリ乳酸、その他の単体又は複合体としてなるプラスチックシート材を加圧加工し、輪郭を打ち抜き加工して形成してある。他の図に示した実施例も同様である。
【００１１】
このシートは、直方体箱状の四側面を構成する正面板部１、右側面板部２，背面板部３、左側面板部４を順次折曲げ罫線５を介して連設し、正面板部１の上下に折曲げ罫線５ａ，５ａを介して蓋片６，７を、蓋片の各先端に折曲げ罫線６ｂ，７ｂを介して差込み片６ａ，７ａを連設し、左右側面板部２，４の上下にそれぞれ折曲げ罫線５ｂを介して折込み片８を連設し、正面板部１の開放側縁に折曲げ罫線５ｃを介して糊代片９を連設し、
さらに、左側面板部４の開放側縁に折曲げ罫線５ｄを介して所定長さの被収納物用保持板部１０を延設し、この保持板部１０は、延設方向中央に支持片１１部分を除いて折曲げ罫線５ｅを形成して、左右保持板部１０ａ、１０ｂとし、該罫線５ｅ上の離隔位置において、一方は左保持板部１０ａ側に、他方は右保持板部１０ｂ側にそれぞれコの字状その他任意形状の切込み１１を設けて、適宜長さの支持片１２、１２を左右対称的に区画形成して構成してある。
【００１２】
保持板部１０は、延設方向幅を正面板部１と右側面板部２の合計幅（背面板部３と左側面板部４の合計幅）分の長さよりも若干短い長さに設定し、すなわち、図２、３に示すように、四側面１，２，３，４を立体形成した箱体を二つ折り状に扁平に折畳んだ折畳み容器側面板部の両外側折曲部間の長さより短い長さＳのものとなるように設定し、支持片１２の切込み方向幅を該短い長さＳ分よりも長く設定し、
左右保持板部１０ａ、１０ｂを形成する罫線５ｅは、両保持板部１０ａ、１０ｂの折曲によって形成される凹部が被収納物１４の収納空間１３として正面板部１側に形成されるように、折曲癖を持たせて形成してある。上記被収納物は、マスカラなどの化粧用具、筆記具などの文房具、その他の任意のものとすることができ、その形状は、円筒状、各筒状、その他の任意形状とすることができる。
【００１３】
上記シートは、図２に示すように、罫線５ｄ介して保持板部１０を内折れさせ、これを挟み込むようにして四側面板部１、２、及び３、４をその間の罫線５を介して二つ折りさせ、罫線５ｃを介して糊代片９を内折れさせて左側面板部４の外側縁に合わせ、ホットメルト接着剤その他の接着剤により固着させて、偏平二つ折り状態の組立容器とすることができる。なお、この加工工程は限定するものではなく他の方法を含めて任意である。
上記二つ折り状の組立容器は、保持板部１０が容器二つ折り幅よりもＳ分だけ短いので、膨らみの出ない偏平折畳み形状として形成することができ、運搬、保管性がよく、取り扱いに優れている。
【００１４】
上記二つ折り状の組立容器は、図３に示すように、四側面中の残りの罫線５、５を内折れさせつつ、直方体状に立体化すれば、罫線５ｅを介して内部の保持板部１０は箱形に沿って断面Ｖ字状に折曲して直方体内に納まり、Ｖ字が開放部を正面板部１に向けて正対し、正面側に被収納物１４の収納空間１３を形成する。この際、容器を立体化する工程中に、蓋面方向の開口部から容器内に操作ピンを差し込むなどして、保持板部１０をＶ字状に折曲するための補助操作を加えるようにしてもよく、任意である。
保持板部１０は、二つ折り状の組立容器の幅よりも短いことにより、保持板部の開放端縁が二つ折り部（右側面板部２と背面板部３間の内折れさせた罫線５部分）に食い込むような状態で二つ折りされることがなく、容器の立体過程で自由に移動できるので、円滑な容器の立体化作業を阻害させることがない。
【００１５】
また、罫線５ｅで保持板部１０をＶ字状に折曲すると同時に、切込み１１によって画成した支持片１２は、罫線を介在させていないので、罫線を介在させていない側の保持板部１０ａ又は１０ｂと直線面状態を維持し、Ｖ字外側方向に逆Ｖ字状に張出し突起することになる。
【００１６】
保持板部１０のＶ字両端辺は正面板部１の両端角部付近に位置する一方、上記のようにＳ分だけ短いので、Ｖ字底部が背面板部３と若干の間隔を置いて浮いた状態となるが、突出した支持片１２、１２が背面板部３に圧接し、容器内での保持板部１０のがたつきを生じさせることがない。
支持片１２は逆Ｖ字状に傾斜して突起することにより、適度な弾性変形が可能であり、保持板部１０の固定状態を維持するとともに、緩衝機能も果たすことができる。
【００１７】
図４は、支持片１２の変形例を示したものである。支持片の構成はこれらに限定されるものではない。
（Ａ）は、中間部で離隔した支持片１２、１２を罫線５ｅ部分から同方向の右保持板部１０ａ側に形成し、両支持片間に逆向きコの字状の切込み１１を形成して、支持片１２ａを左保持板部１０ｂ側に形成した構成例である。
（Ｂ）は、中間部を罫線５ｅとし、罫線の上下両端部にそれぞれ左右保持板部１０ａ、１０ｂに対称的な支持片１２ｂ、１２ｂを形成した構成例である。
（Ｃ）は、罫線５ｅの中間部に、左右保持板部１０ａ、１０ｂに片側づつ膨出した波形状の切込み１１を形成して、円弧舌片状の対称的な支持片１２ｃ、１２ｃを形成した構成例である。
（Ｄ）は、罫線５ｅの中間部に、左右保持板部１０ａ、１０ｂのいずれか一方にのみ切込み１１を形成して一つの支持片１２ｄを形成した構成例である。
【００１８】
図５は、保持板部１０の変形例を示したものである。保持板部の構成はこれらに限定されるものではない。
（Ａ）は、保持板部１０の延出方向中間部に２本の折曲げ罫線５ｅ、５ｅを形成し、保持板部１０を断面台形状に折曲して収納空間１３を形成することができるようにした構成例である。支持片１２ｅは、各罫線５ｅ、５ｅから内側の保持板部内に向かって切込みを設けて形成することができる。
（Ｂ）は、保持板部１０内に罫線を設けず、保持板部を断面円弧状に湾曲させて収納空間１３を形成することができるようにした構成例である。支持片１２ｆは、湾曲面中間部に切込みを設けて形成することができる。
【００１９】
上記保持板部１０は主として被収納物を周側面から保持するものである。これに対し、被収納物を上下方向から支持し、或いは上下方向に空間部を維持した状態で被収納物を支持する構成とすることができる。
図６、７において、上記構成の保持板部１０を左側面板部５の上部寄り部位に罫線５ｄを介して延設し、左側面板部５の下部に被収納物を底上げ状態で収納できるような空間部相当の高さを残し、この下部から折り曲げ罫線５ｆを介して調整板部１０ｃを延設し、調整板部１０ｃは組立てた容器内で罫線を軸に回動可能な長さ、好ましくは正面板部１の横幅の半分〜全幅分程度の長さを有して形成してある。
図示しないが、調整板部１０ｃは、左側面板部５の下部のみならず、上下部或いは上部に形成することができる。
【００２０】
図７の如く、調整板部１０ｃを下部に形成することにより、シートを組立て立体化すれば、Ｖ字状の保持板部１０により形成された収納空間１３に被収納物１４を定置し得ると同時に、調整板部１０ｃを折曲して収納空間１３内に交差させ、収納空間下側に位置させることにより、被収納物１４の底部が調整板部上に載置することになり、組立容器下部に空間部を残したまま安定した収納状態を維持することが可能となる。同時に、被収納物の上下方向への抜け外れが阻止できるので、盗難防止に役立つ。また、容器に比して小さいものを収納する場合に外観を良くする。
【００２１】
図８、９は、上記図６とは異なる実施形態を示すものであり、保持板部１０を左側面板部５の全長近くにわたる長さで罫線５ｄを介して延設し、切込み１１による支持片１２はこの保持板部１０内の上部寄り部位に形成し、保持板部１０内の下部には被収納物を底上げ状態で収納できるような空間部相当以上の高さを残し、この保持板部下部内の中央部の底上げ位置に、水平な切込み線１５を形成するとともに、この切込み線１５の中央と両端位置から保持板部下端に至って折り曲げ罫線５ｇを垂下形成することにより、折曲張出し可能な調整板部１０ｄを形成してある。
【００２２】
図９の如く、シートを組立て立体化すれば、Ｖ字状の保持板部１０により形成された収納空間１３に被収納物１４を定置し得ると同時に、調整板部１０ｄを折曲して収納空間１３内に張出し交差させることにより、これが収納空間下側に位置するので、被収納物１４の底部が調整板部１５上に載置することになり、組立容器下部に空間部を残したまま安定した収納状態が維持されることになり、図６の構成と同様の作用効果を奏する。
【００２３】
図１０、１１は、上記とは異なる被収納物の定置構成を示すものであり、正面板部１の中央部に、被収納物の正面部分を受けてこの部分に当接可能な内方凸部１６ａを周縁に形成した内面凹部１６を設けてある。内方凸部１６ａと内面凹部１６は，図１１（Ａ），（Ｂ）の如く被収納物部分に接面するように形成することもでき、或いは同（Ｃ）の如く点接触乃至線接触状態で接触するように形成することもできる。
図１１の如く、シートを組立て立体化すれば、Ｖ字状の保持板部１０により形成された収納空間１３に被収納物１４を定置し得ると同時に、正面板部の内方凸部１６ａが被収納物に当接し、その一部が内面凹部１６に納まるように位置して、ずれを生じさせない安定状態が維持されることになる。
上記凹凸は浅く形成しておけば、プラスチックシートに可撓性があるので、凹凸が被収納物の収納に支障を生じさせることはない。
【００２４】
上記各実施形態において、少なくとも保持板部１０に箔押しその他の適宜印刷により着色乃至模様を形成することができる。保持板部が装飾されることにより、例えば屏風を背にし或いは優れた美感の装飾面に被収納物が収納されている外観を呈することができるので、展示商品に高級感を与え、或いは趣味性を与えることができる。
なお、上記各実施形態の説明は一例を示したものであり、保持板部と糊代片の連設位置を逆にして形成し、容器周側面を直方体以外の形状として形成し、或いは他の変形が可能であり、本発明はそれらを含むものである。
【００２５】
【発明の効果】
上記のように本発明によれば、被収納物用保持板部を内装させた状態で、容器を偏平二つ折り状態に折畳んで運搬、保管を便利にでき、被収納物の包装時に容器を立体化するだけで被収納物を安定的に収納することができるプラスチックシート組立容器を提供することができる。
上記組立容器は、保持板部を容器の二つ折り幅よりも短く形成することにより、膨らみの出ない偏平折畳み状態とすることができるとともに、保持板部の開放端縁を容器の二つ折り部に食い込むような状態で二つ折りさせることがなく、容器の立体化工程で保持板部を自由に移動させ、容器の立体化作業を円滑に行わせることができる。また、寸法制約が少なくなるので、容器の正背面、左右側面の広さを任意に設定でき、包装・広告媒体としての効果を高めることもできる。
上記構成によれば、被収納物の収納作業が簡単に行なうことができ、しかもがたつきなく安定的に保持状態を維持することができる。
また、調整板部を形成することにより、上下方向にも空間部を持たせて安定した収納が可能となり、盗難防止にも役立ち、保持板部を装飾印刷することにより被収納物の展示効果を一層高め得る。

BACKGROUND OF THE INVENTION
The present invention relates to a plastic sheet assembly container in which a holding plate part capable of forming a storage space is formed in the container.
[0002]
[Prior art]
An assembly container is made by forming a folded ruled line on a plastic sheet such as amorphous polyethylene terephthalate (A-PET) having good transparency and rigidity. For example, as in Patent Document 1, a conventional container of this type is formed by connecting a front back plate part and left and right side plate parts through a bent ruled line, and a lid piece is bent up and down from the front or back plate part through the bent ruled line. A flap that is arranged continuously and extends from one of the plate portions or pieces through the ruled line to the inside of the container, and after the container is assembled and three-dimensionalized, the inner peripheral surface of the container, that is, the four sides It was the thing of the structure made to press-fit in a container so that it might closely_contact | adhere to each inner surface of a faceplate part, and to hold the to-be-contained object.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 2001-139019
[Problems to be solved by the invention]
With the configuration as described above, after assembling and three-dimensionalizing the container, it is necessary to fold the flap, or press and fix it in the container while holding the object to be stored in the folded one In addition, there is a problem that it is difficult to separate the container manufacturing and assembling process from the packaging process for storing the objects to be stored, and it is difficult to sufficiently rationalize the container manufacturing and distribution process.
[0005]
As an improvement of the above, in the process of assembling the container by adhering the glue margin pieces, the flap is folded into the container so that the assembly container can be folded and folded and transported and stored in a flat folded state. It is preferable if the container structure can be three-dimensionalized during packaging. In this case, the internal flap must be configured so as not to hinder the three-dimensional work, and in particular, the flap that forms the storage space in the container can be smoothly interlocked with the folding or three-dimensionalization of the container. desired. As such, the configuration shown in FIGS. 12 and 13 can be considered. This is because a flap 22 is connected to one side edge of a side plate portion 21 that can be folded and assembled into a container via a folding ruled line 23, and the flap 22 is folded into the container, and then a paste margin piece 24. To form an assembly container. When the container is three-dimensionalized, the flap 22 is V-shaped in the container, and a storage space for the object 25 is formed in the V-shaped recess. is there.
[0006]
However, in the case of this configuration, when the assembly container is folded in a flat bi-fold shape with the ruled line 23 and the diagonal line ruled line folded, the flap 22 is sandwiched in the folded container. However, if the flap is longer than two folding widths, the flap does not extend flat, so the container cannot be folded flat, hindering transportation and storage. If the V-shaped flap rattles or the object to be stored rattles, there is a problem that the product value is lowered, and when the lengths match, the flap edge bites into the inside of the folded portion, and the flap is V There is a possibility that problems such as difficulty in forming a letter occur, and there is a problem that the dimension constraint is too strong.
The present invention solves the above-mentioned problems, and with the flap, i.e., the holding plate for the object to be stored, the container can be folded and folded in a flat and folded state for convenient transportation and storage. Sometimes, a plastic sheet assembly container capable of stably storing an object to be stored only by three-dimensionalizing the container is provided.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a front plate part, a right side plate part, a back plate part and a left side plate part that constitute four sides of a rectangular parallelepiped box , and a lid piece that constitutes the box-like lid surface) And a plastic sheet is punched out into the outline in which the adhesive margin piece is connected to the side edge of the front plate part via the ruled line, and each face plate part of the plastic sheet and In a plastic sheet assembly container that is assembled in a box shape by bending each piece at each ruled line and fixing the glue margin piece to the outer edge of the left side plate part, it enters the container from the side end of the left side plate part via the ruled line The holding plate portion that can be folded is extended to have a length capable of forming a storage space for the object to be stored, and a support piece that can contact the inner surface of the back plate portion is formed in the intermediate portion of the holding plate portion. And the front plate part in the storage space And having a structure that can abut irregularities to pay have been accommodated article is formed.
The holding plate portion is a length that substantially extends between both side plate portions of the left side plate portion continuously provided with the holding plate portion and the right side plate portion facing the holding plate portion in a state where a storage space is formed by bending or bending the intermediate portion. In the state extended and flat, it is preferable to form it with a length shorter than the length between both ends of the front plate portion and the right side plate folded flat.
[0008]
The present invention is also characterized in that a plastic sheet assembly container is formed by forming an adjustment plate portion that can be bent and extended in a storage space at least above or below the holding plate portion.
In addition, a ruled line is formed in the center of the holding plate portion, and the holding plate portion is configured to be folded into a V-shaped cross section with the front plate portion side being a wide open portion in a box-shaped container. Can do.
Furthermore, at least the holding plate portion can be formed with a foil stamping or other printed pattern to enhance the decoration effect.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an exemplary embodiment of the present invention will be described with reference to the drawings.
1 to 3 are diagrams showing an embodiment of the plastic sheet according to the present invention, FIGS. 4 and 5 are diagrams showing modifications of the support piece and the holding plate, and FIGS. 11 and 12 are comparison diagrams of the present invention.
[0010]
FIG. 1 is a plastic sheet for forming a rectangular parallelepiped box-shaped assembly container. A-PET, polypropylene, polyethylene, polycarbonate, a biodegradable resin such as polylactic acid, and other plastic sheet material as a simple substance or a composite are used. It is formed by pressing and punching the contour. The same applies to the embodiments shown in the other figures.
[0011]
In this sheet, a front plate portion 1, a right side plate portion 2, a back plate portion 3, and a left side plate portion 4 constituting four sides of a rectangular parallelepiped box shape are sequentially connected via a folding ruled line 5. Lid pieces 6 and 7 are connected up and down via bent ruled lines 5a and 5a, and insert pieces 6a and 7a are connected to the ends of the cover pieces via bent ruled lines 6b and 7b, respectively. Folding pieces 8 are continuously provided on the upper and lower sides of the front plate part 1 via the folding ruled lines 5b, and the paste margin pieces 9 are provided on the open side edge of the front plate 1 via the bent ruled lines 5c.
Further, a holding plate portion 10 for the object to be stored having a predetermined length is provided on the open side edge of the left side plate portion 4 via a folding ruled line 5d, and the holding plate portion 10 is provided with a support piece 11 at the center in the extending direction. Folded ruled lines 5e are formed except for the portions to form left and right holding plate portions 10a and 10b, one at the left holding plate portion 10a side and the other at the right holding plate portion 10b side at spaced positions on the ruled line 5e. Each of the U-shaped or other arbitrarily-shaped cuts 11 is provided, and the support pieces 12 and 12 having appropriate lengths are divided and formed symmetrically.
[0012]
The holding plate portion 10 sets the extending direction width to a length slightly shorter than the total width of the front plate portion 1 and the right side plate portion 2 (the total width of the back plate portion 3 and the left side plate portion 4), That is, as shown in FIGS. 2 and 3, the length between the outer side bent portions of the side plate portion of the folding container in which the box body in which the four side surfaces 1, 2, 3 and 4 are three-dimensionally folded in a flat shape is folded. Set to be shorter than the length S, and set the width of the support piece 12 in the cutting direction longer than the short length S,
The ruled line 5e forming the left and right holding plate portions 10a and 10b is formed such that a recess formed by bending of both holding plate portions 10a and 10b is formed on the front plate portion 1 side as the storage space 13 of the article 14 to be stored. It is formed with bent folds. The stored item may be a makeup tool such as mascara, a stationery such as a writing tool, or any other arbitrary shape, and may have a cylindrical shape, a cylindrical shape, or any other arbitrary shape.
[0013]
As shown in FIG. 2, the sheet has the holding plate portion 10 folded inward via the ruled line 5d, and the four side plate portions 1, 2, 3 and 4 are interposed via the ruled line 5 between them. Fold it in half, fold the glue margin piece 9 inward through the ruled line 5c, align it with the outer edge of the left side plate portion 4, and fix it with a hot melt adhesive or other adhesive to make an assembly container in a flat bi-fold state. be able to. Note that this processing step is not limited and is arbitrary including other methods.
Since the holding plate portion 10 is shorter than the half width of the container by folding, the bi-folded assembly container can be formed as a flat folded shape that does not bulge, has good transport and storage properties, and is excellent in handling. ing.
