【発明が解決しようとする課題】
アンプル，バイアル，注射筒，ドリンク用瓶等の医薬用容器の箱は、該箱の収納物が使用される以前に破損しないことが最大の課題であり、該課題の解決のために製造コストを絡めて、有効な緩衝機能と強度を持つような構造と材料からなる前記箱が模索されているが、決め手となるようなものが出来ていない。
【０００７】
本発明では、上述の課題の達成のために、次に示した６つの主要問題の解決を目的とし達成した。
１）組立に際し材料の端部での怪我を防止し、環境に対する順応性を持つリサイクル可能な材料を使用する。
２）箱を一体組立型として構成する材料と部品の点数を大幅に削減し、該部品の加工・仕上に要する時間を逓減する。
３）箱の仕上工程を簡略化し自動組立と要員当たりの生産能力を拡大する。
４）箱のふたと身双方に緩衝機能と耐圧強度を大幅に増す構造を選択する。
５）医薬用容器の自動充填を可能ならしめる。
６）用済後の不正使用や封緘紙の剥離再貼付等の改ざん防止対策を備えた組立箱とする。
【０００８】
【課題を解決するための手段】
本発明は、超低密度の特殊板紙を使用し、ふたの外・内天井板と身の外・内底板の周囲に夫々連接した前・横・後の外・内各側板と横内底板とフラップを組合せ配設し、ふたの外天井板と身の外底板を連接する共通の後外側板を配設し、ふたの横外側板と外底板の横外側板の間に形成された四辺形部分を四つに区分し、四辺形と２つの三角形を残し１つの三角形を除いた構成とし。２つの三角形と四辺形を夫々連接し、各境界に折曲げ用けい線と三角形の面上に折曲げ用けい線を設けることにより、１つの三角形が二個の三角形として働く構造の特殊ジョイントを配設し、ふたと身を一体化した接着材料の使用を抑えた構成の打ち抜き材とし、該打ち抜き材に組立て緩衝手段と改ざん防止手段と仕切材の移動防止手段を備えたことを特徴とする組立箱である。
【０００９】
【発明の実施の形態】
組立箱の各部材に対する呼称は図１の斜視図に付記したように、半開状態の該組立箱を閉じた状態とした時の開け側を前面として前・横・後とし、ふたの天井板と底板に関しては外・内と幅を加えた各組合せで、側板とフラップに関しては外・内と高さを加えた各組合せで夫々を区分し表現した。
【００１０】
第１の課題に対する解決手段は、特殊板紙の対象として木材その他の植物から抽出した繊維の集合体からなるパルプを箱の材料に選んだことであり、該パルプは不要成分を除いた繊維を板状に抄いた製紙原料である中間製品で、最終製品の紙に較べると坪量が同じでも厚みがあり超低密度であるので軽量で柔らかく、平判もしくは巻取られたままのロール状で保存される。
【００１１】
パルプの種類には、原料，製造方法，用途等により様々な分類があり、その一部を挙げると原料別では麻パルプ，リンターパルプ，わらパルプ，針葉樹か広葉樹による木材パルプ，合成パルプ等、製造方法別では機械パルプ，クラフトパルプ，ソーダパルプ等、用途別では溶解パルプと製紙用パルプ等があるが、汎用性と価格面を考慮すると木材によるクラフトパルプ，ソーダパルプから選択した製紙用パルプが好ましい。
【００１２】
製紙用パルプの諸元のうちで、坪量の範囲は通常４０〜３００ｇ／ｍ² 、好ましくは１００〜２７５ｇ／ｍ² 、より好ましくは１６５〜２５０ｇ／ｍ² とし、厚みの範囲は通常０．２〜１．５ｍｍ、好ましくは０．７〜１．５ｍｍ、より好ましくは０．９５〜１．４ｍｍである。
【００１３】
パルプは、上記のように厚みの割に坪量が小さいため全体が柔軟性に富み、打ち抜き材を人手で折曲げ組立ても、打ち抜き材の切断面で怪我をする恐れの少ない安全な材料で、組立箱が不要になっても溶解による再パルプ化（リサイクル）が可能で、燃焼処理でも発熱により炉を損傷したり異臭を放つことがない。
【００１４】
第２の課題に対する解決手段は、ふたと身を別々に製造し順次一体化した従来の方法に較べ、本発明では構造上一体化できない部品のみを除き、最初の段階から前記ふたと身を一体化した構成の組立箱として、プレスにより打ち抜き材料点数と部品点数の削減を達成した。
【００１５】
本解決手段により組立箱を構成する材料点数と部品点数と該部品の仕上工程の様子は表１（Ｂ）と表２（Ｂ）とに示した通りであって、本発明以前の方法が必要とした表１（Ａ）と表２（Ａ）に記載された内容と比較することにより、目的が充分に達成されていることが十分に理解されよう。
【００１６】
本発明のふたと身を一体化した構成の組立箱は次の特徴を包含する。
1)ふたを身から開いた際、両者が連接部分を境にして１８０°以上に開かず、閉じる際に起こりがちな外側板が内側板の中に入り込むトラブルを防止するため、前記ふたと身の両横外側板の間に特殊なジョイントを設置した。
2)ふたの側板部分と天井板部分，身の側板部分と底板部分，前記ふたと身の共通した連接部分（後側板）は全て２重構造とし、２重に折曲げられた側板等の反発が強い部分のけい線は、カッターによる切り目を間欠的に入れたリードけい線として反発を弱めた。
3)側板相互間のフラップも２重（１重部分を含む）としたが、該フラップを収納する隙間を提供する側板に連接して前記２重フラップの厚み相当分の折しろを設け、前記フラップのない部分では直折りとした。
4)単一材料による一体化構造では糊付部分をふた両側面内側のみに減少した。
【００１７】
図３に示すように、ふたの天井板に連接した横外側板と身の底板に連接した横外側板の間に設けられた特殊なジョイントは、両横外側板の高さの２辺と前記天井板と底板に挟まれた連接部分である後外側板の高さにより形成された四辺形部分を、折曲げけい線と切断線で１つの四辺形と３つの三角形に区分し、該区分から前記連接部分の端部に接する１つの三角形を取り除いた構成となっている。
【００１８】
１つの四辺形と２つの三角形のうち、ふたの外天井板に連接した横外側板の高さを１つ目の三角形の１辺とし、身の外底板に連接した横外側板の高さを四辺形の１辺とし、両形の間に残りの三角形を連接配置して、前記１つの四辺形と２つの三角形が一点で交わる位置を点ｅとし、外天井板と外底板に挟まれた連接部分である後外側板の高さの中間点ｆから点ｅを通る法線と線分ａｂ´との交点ｆ´の関係は、ｅｆ´間の距離を交差位置Ｈとすると次式、
Ｈ＝｛連接部分の高さ寸法＋材料の厚み寸法×２｝×０．５５
により表され、こうして得た点ｅと各三角形の頂点ａ，ｂ，ｃを結んで点ｅと辺ａｅから角度∠ａｅｇを９０°に採ると辺ｃｄ上の点ｇの位置が決定し、折曲げ用けい線ａｄ，ｂｃ，ｃｅ，ｅｆ，ｅｇが順次線引きできる。
【００１９】
本発明の組立箱では２重構造の側板を円滑に折曲げ２重か１重のフラップを巻込み固定する部分は２〜６箇所で、原則として半数が対称的な位置関係にあり、夫々が次の様な寸法範囲に決められている。
1)ふたの両側面が外側へ開き易くなるのを押さえるための２重フラップのうち、内側にくるフラップの高さを連接した側板の高さよりもｔ₁ （材料厚み）ｍｍ、外側にくるフラップの高さをｔ₂ （材料厚み＋０．５）ｍｍだけ短くする。
2)身の前面が手前側に倒れ（開き）易くなるのを押さえるための２重フラップのうち、内側にくるフラップの高さを連接した側板の高さよりもｔ₁ （材料厚み）ｍｍ、外側にくるフラップの高さを連接した側板の高さよりもｔ₂ （材料厚み＋０．５）ｍｍだけ短くする。
3)ふたが開いた時、身の後側方向に収容物が移動しないように後面側板に連接して設けた１重フラップの高さを該側板の高さよりもｔ₂ （材料厚み＋０．５）ｍｍだけ短くする。
【００２０】
外・内側板間の２重フラップを巻込むように収納する重合（合口）部分は、前記フラップの厚み相当分の折しろを持ち、外・内側板の折曲げによる反発力を緩和するために、好ましくは前記折しろを材料厚みｔ₁ の２〜３倍の範囲から組立箱の部位に合わせて選択使用し、前記フラップを収納しない部分では直折りとして、そのけい線を挟んだ折目周辺の材料自体を自己圧縮して弾性力を高め、その力を利用して先に置かれた嵌合部分の係止効果を高めた。
【００２１】
第３の課題に対する解決手段は、既述の第１と第２の課題に対する解決手段により副次的に生まれてくる効果も大きく寄与するが、ふたと身を一体化することによる工程の集約化により生まれる効果が最大で、さらに組立箱は殆ど直線の集合体であり一見複雑な形状であっても組立は容易になった。
【００２２】
工程の集約化による効果は、余分な工程を削除し必要な加工を集中的に同時もしくは連続して施すことにより得られるものであり、本解決手段による箱の仕上工程が簡素化された様子は表２（Ｂ）に示した通りで、従来方法が必要とした表２（Ａ）に記載された仕上工程の内容と比較することでより明らかになる。
【００２３】
本解決手段による効果を箱の生産数で見たとき、打ち抜き材を使用し自動製箱機による大量生産、糊付け等の一部を自動化し組立要員の手作業による小量生産の何れの作業をとっても、従来方法に比べて組立要員当たりの生産数を飛躍的に増加することを可能とした。
【００２４】
第４の課題に対する解決手段は、既述の第１と第２の課題に対する解決手段による効果に加えて、超低密度の製紙用パルプを使用する際に強度保持の面から必然的に板厚みが増加するが、該製紙用パルプは繊維の隙間に大量の空間を保持するので重さを増すことなく、組立箱の緩衝機能を大幅に増加することを可能とした。
【００２５】
また組立箱全体が２重構造で、前・横で外・内側板同士の間で固定されるフラップも２重としているので、既述の製紙用パルプの材料自体が本来持つ緩衝機能に加えて、前記２重構造により構成された隙間の空気層の存在が緩衝機能をより高める相互作用を持ち、さらに２重構造が前記組立箱の積層等に対する強度、即ち耐圧強度を高める結果となっている。
【００２６】
第５の課題に対する解決手段は、前述の第４の課題に対する解決手段による効果が大きく寄与したもので、著しい緩衝機能の増加がアンプル，バイアル，注射筒，ドリンク用瓶等の割れやすい医薬用容器を自動充填する際に受ける衝撃力を良く吸収し、且つ組立箱の耐圧強度の向上も併せ自動充填機への装着を可能とした。
【００２７】
第６の課題に対する解決手段は、通常片開きの箱では収納物を格納後ふたを閉じ、身との合わせ目に封緘紙を使用するが、組立箱が製紙用パルプで出来ているために、貼着された封緘紙を一端剥離すると該製紙用パルプの表面が該封緘紙に付着したまま剥離し、前記封緘紙は再度糊を使用しなければ貼着できなくなる特徴がある。
【００２８】
また本発明になる組立箱は、ふたの開閉により重合（合口）部分が開かないようにフラップの長さを前記ふたの前幅の２／５〜１／２の範囲を好ましい長さとしたので、一度組立た箱は毀損なしに容易に解体できず、従って解体後の廃却品が再使用されることは難しく、封緘紙の着脱と廃却品の再使用等を含めた不正行為、即ち改ざん行為を防止することが可能で、これは従来方式の硬紙で短いフラップを使用した箱では得られない機能である。
【００２９】
長方形の組立箱で身の横外・内側板に巻込まれるフラップの長さは、前記ふた幅の１／２としても、該フラップの長さと高さの割合がふたのそれに較べて小さく抜ける可能性を残すので、製紙用パルプから採寸可能な範囲で左右の２重フラップの一方を長く他方を短くし、上・下のフラップではこの関係を逆として夫々のフラップを重ね合わせ、箱を組立るとフラップがより抜けにくくなる。
【００３０】
本発明が包含する以上の解決手段は、いずれも極めて大きな効果を伴うことが理解されよう、またパルプは板状化の前後での着色や、板状化後の打ち抜き前後または組立後の印字を可能とした他に、組立箱全体が各部位の組立の際に極力糊を必要としない構造としたため廃却品の解体が容易になる特徴を備えた。
【００３１】
従来方法により造られた箱と本発明より造られた組立箱に使用された材料の単位重量を表１（Ａ，Ｂ）に併記したが、これ等の材料を使用して出来上った箱の総重量は後者が小さく前者の７０％程度で、加えて製作に要する手間と製品の持つ緩衝機能または価格の点でも後者が圧倒的に前者に優り、前者の優位点は僅かに美観の面のみである。
【００３２】
製紙用パルプは、その表面に多数の微細な開口と内面に多数の空間を保有するので液の浸透性が高く、従来使用されている一般糊（主成分：アクリル酢ビ共重合樹脂・粘度１０，０００〜１２，０００ｃｐｓ・濃度５０〜６０％）では接着が充分でなく、初期付着力が強く安定性のある専用糊〔（主成分：特殊共重合ビニール系樹脂・粘度１４，０００〜１６，０００ｃｐｓ・濃度５０〜６０％）例えば株式会社ヒラノヤ製のダイレクトボンドＶＫ−１０が好ましい〕が使用された。
【００３３】
使用する製紙用パルプは板状化のための抄紙過程の段階で、内部繊維に方向性が出来るために組立箱の外面に化粧紙を使用しないときは、該組立箱に外力が働くと該繊維の流れに沿った筋目が現れるが、この現象自体は前記組立箱の強度や緩衝機能や商品性を損なうものではない。
【００３４】
本発明になる組立箱の持つ作用は、製紙用パルプ自体が保有する柔らかさと緩衝機能と前記組立箱の生産上の対策であるふたと身の一体化構造と強度上の対策である２重構造との相乗効果により、該組立箱の生産能率を向上し高い耐圧強度と高い緩衝機能を合わせ保持することを可能とした結果、割れ易い医療用容器の自動充填をも可能とした。
【００３５】
【実施例】
図１に示した形状は、本発明になる組立箱１（縦２００ｍｍ×横１００ｍｍ×高さ２４．５ｍｍ）の斜視図で、超低密度の特殊板紙（坪量２５０ｇ／ｍ² ，厚み１．４ｍｍ）を使用して、図２のふた２と身３を一体化した構造の組立用ブランクスを、ホブスト社製の平打抜機オートプラテン（主仕様：ＳＰ−１０２ＣＥＲ，５５００回転／時間，圧力１５ｔ）で裏から打ち抜いた。
【００３６】
ブランクスのふた両面の糊貼はホブスト社製の自動糊貼機（主仕様：ドミノー１１０Ｍ，７０００枚／時間）で、糊は株式会社ヒラノヤ製のダイレクトボンドＶＫ−１０（主成分：特殊共重合ビニール樹脂，粘度１５，０００ｃｐｓ／３０°Ｃ，濃度５５％）を使用し、糊の塗布方法は転写タイミング様式を採用して、糊量を２７ｇ／ｍ² 塗布して製品とした。
【００３７】
本発明になる組立箱の実施例と従来通りの改善前の箱の生産量を比較した結果、生産量は１．７倍強の増加となった。
実施例：７，０００ケ／日÷８時間＝８７５ケ／時間÷８人＝１１０ケ／時間
改善前：４，０００ケ／日÷８時間＝５００ケ／時間÷８人＝６３ケ／時間
【００３８】
図２は、本発明になるふた２と身３を一体化した組立箱１の展開図で、右から左にかけてふたの内天井板２４と前内側板２５とフラップ収納スペース構成用の折しろ５₁ と前外側板５と外天井板４とふたと身の連接部分に相当する共通の後外側板６と身の外底板７と前外側板８と前内側板２８と内底板２７と後内側板２６とが順次連接する。
【００３９】
上・下にたいしては、外天井板４の上に横外側板４Ａと横内側板１４Ａがあり夫々の右方向にフラップ４ＡＡ，１４ＡＡ、下に横外側板４Ｂと横内側板１４Ｂがあり、夫々の右方向にフラップ４ＢＢ，１４Ｂが連接し、外底板７の上に横外側板７Ａとフラップ収納スペース構成用の折しろ７Ａ₁ と横内側板１７Ａと内底板２７と嵌合する横内底板１７Ａ₃ 、下に外側板７Ｂとフラップ収納スペース構成用の折しろ７Ｂ₁ と横内側板１７Ｂと内底板２７と嵌合する横底板１７Ｂ₃ が連接し、前外側板８の上にフラップ８ＡＡと下にフラップ８ＢＢが連接し、前内側板２８の上・下にフラップ２８ＡＡ，２８ＢＢが連接し、内底板２７を挟むように後内側板２６の上・下にフラップ２６ＡＡ，２６ＢＢが連接し、ふたの横外側板４Ａ，４Ｂと身の横外側板７Ａ，７Ｂが特殊ジョイント６Ａ，６Ｂで連接され全てが一体化されている。
【００４０】
上記の各部位の内、ふたは外天井板４と前外側板５と横外側板４Ａ，４Ｂとフラップ４ＡＡ，４ＢＢと横内側板１４Ａ，１４Ｂとフラップ１４ＡＡ，１４ＢＢと内天井板２４と前内側板２５とで構成され、身は外底板７と横外側板７Ａ，７Ｂと前外側板８とフラップ８ＡＡ，８ＢＢと横内側板１７Ａ，１７Ｂと後内側板２６とフラップ２６ＡＡ，２６ＢＢと内底板２７と横内底板１７Ａ₃ ，１７Ｂ₃ と外内側板２８，フラップ２８ＡＡ，２８ＢＢとで構成され、各板間には一点鎖線で示した折曲げけい線または一点鎖線と太線とで示した切り目付き折曲げけい線が夫々設けられる。
【００４１】
特殊ジョイント６Ａ，６Ｂは、ハッチング部分６Ａ₄ ，６Ｂ₄ が除去された残り２つの三角形６Ａ₁ ，６Ａ₂ と６Ｂ₁ ，６Ｂ₂ と四辺形６Ａ₃ と６Ｂ₃ とから構成され、横内側板１７Ａには切り目１７Ａ₁ ，１７Ｂ₁ があり、その切り目に沿って身３の内側に片持梁状に押し出し、身３内面に挿入された仕切材３１等の抑え止めの役目をなさしめ（図１参照）、ふたの横内側板１４Ａ，１４Ｂの切り欠き１４Ａ₁ ，１４Ｂ₁ は、内天井板２４の突起２４Ａ₁ ，２４Ｂ₁ をけい線２４Ａ₂ ，２４Ｂ₂ に沿い折曲げて立てておくと組立時に嵌合し、ふた２の組立部分の剥離を抑止する。
【００４２】
ふた２の横内側板１４Ａ，１４Ｂの帯状のハッチング部分１４Ａ₂ ，１４Ｂ₂ は糊付部分で、本発明の箱が殆ど折曲げ部分の組合せで組立を可能としたことを示すもので、また図２の展開図が糊付部分の部材を最初に折曲げ接着することにより、該糊付部分が事後の組立の支障にならないように配慮された一体化構造であることを、以下順を追って詳細に説明をする。
【００４３】
図２において、ふた２の横外側板４Ａ，４Ｂの方向に横内側板１４Ａ，１４Ｂを間のけい線（折曲げ用のプレスによる押し溝で以下同じ）に沿い１８０°折曲げて同板に糊接着し〔図５（Ａ）参照〕、その儘の状態で外天井板４側に横外側板４Ａ，４Ｂを間のけい線に沿い９０°折曲げて起こすが、その際同時に身の底板７側に横外側板７Ａ，７Ｂを間のけい線に沿い９０°折曲げて起こしても、或いは別々に折曲げても特別問題はない。
【００４４】
長さＬを外天井板４の前幅Ｗ₁ の１／２としたフラップ４ＡＡ，４ＢＢと１４ＡＡ，１４ＢＢを９０°折曲げ〔図５（Ｂ）参照〕、外天井板４に連接する前外側板５を外天井板４側に間のけい線に沿い９０°折曲げるが、予め該フラップの高さと連接する側板の高さＷ₂ ，Ｗ₃ との寸法（〔００１９〕項参照）と前記フラップと連接する部材との間にも、折曲げ用けい線に必要な重なり部分の寸法が考慮されているので、折曲げに際して無理を生じることはなく、前記フラップは１４ＡＡは４ＡＡに１４ＢＢは４ＢＢに容易に折曲げて重ねられる。
【００４５】
次に、フラップ収納スペース構成用の折しろ５₁ ，前内側板２５，内天井板２４を順次けい線に沿い内か外方向に９０°折曲げるが、内天井板２４にはフラップを巻込んだ側板を固定する役目も兼ねるため、けい線２４ｃには図４の拡大図のように１０ｍｍ間隔の切り目を間欠付与し、巻込み後の側板による折込み部分に掛かる過大な反発力を緩和する。
【００４６】
内天井板２４を外天井板４に重ねる際、先に重ね合わせた横外・内側板４Ａ，１４Ａと横外・内側板４Ｂ，１４Ｂを、やや外側に開き横内側板１４Ａ，１４Ｂの高さＷ₃ を横外側板４Ａ，４Ｂの高さＷ₂ に較べ（材料の厚み＋０．５）ｍｍ分短くしたことにより生じた隙間に、内天井板２４の両端２４a ，２４b を挿入込させると横内側板の端面１４ａ，１４ｂ で押さえられ、さらに切り欠き１４Ａ₁ ，１４Ｂ₁ と突起２４Ａ₁ ，２４Ｂ₁ を嵌合させるとふた２の組立が完了する〔図５（Ｃ）参照〕。
【００４７】
身３の組立には、前外側板８と前内側板２８と内底板２７と後内側板２６とを順次折曲げるが〔図６（Ａ）参照〕、前外側板８と前内枠板２８の間のけい線には、折しろ５₁ ，７Ａ₁ ，７Ｂ₁ に相当する部分を設けてなく内底板２７に働く折曲げによる反発力が大き過ぎないように緩和するために、折曲げけい線２６ｃ，２８ｃにもけい線２４ｃと同様に切り目を付与している。
【００４８】
フラップ８ＡＡを２８ＡＡに８ＢＢを２８ＢＢに夫々重ね合わせ、同様にフラップ２６ＡＡ，２６ＢＢを夫々の間のけい線に沿い９０°折曲げ、しかるのち外底板部７に内底板２７を重ねて合わせ、外底板７の横外側板７Ａ，７Ｂを間のけい線に沿い９０°折曲げた後、折しろ７Ａ₁ ，７Ｂ₁ と横内枠板１７Ａ，１７Ｂと横内底板１７Ａ₃ ，１７Ｂ₃ を、夫々の間のけい線に沿い９０°折曲げると前記フラップは巻込み固定され、台形状切り口１７ａ，１７ｂの横内底板１７Ａ₃ ，１７Ｂ₃ は外底板７に接すると共に内底板２７の船底状切り口２７ａ，２７ｂと嵌合〔図６（Ｂ，Ｃ）参照〕するが、前記フラップと連接する側板の高さｗ₂ ，ｗ₃ ，ｗ₄ との寸法（〔００１９〕項参照）にも、前記フラップと連接する部材間またはけい線の位置にも折曲げによる重なり寸法が考慮されている。
【００４９】
身３の内面に挿入された台紙３２と波状の成型紙３３とでなる仕切材３１が身３の中で移動しないようにするため、横内側板１７Ａと１７Ｂの各面上に備えた切り目１７Ａ₂ ，１７Ｂ₂ を、身３の内面に片持梁状に押し出して抑え止め１７Ａ₁ ，１７Ｂ₁ 〔図１，図６（Ｃ）参照〕とすると、その先端は仕切材３１を抑える板バネとしての役割を果たし、切り目１７Ａ₂ ，１７Ｂ₂ の両端に付した曲線は押し出し時の切り目基部の破損を防止するために役立ち、けい線１７Ａｃ，１７Ｂｃは折しろ７Ａ₁ ，７Ｂ₁ からくる反発力を軽減するため、既述のけい線２４ｃ，２６ｃ，２８ｃと同種の構造である。
【００５０】
身３側のフラップ２６ＡＡ，２６ＢＢが１重であるために、側板の隅に出来る合口部分からの抜け易さを防止するために、フラップ８ＡＡ，８ＢＢ，２６ＡＡ，２６ＢＢ，２８ＡＡ，２８ＢＢの各長さｌを外底板７の横幅ｗ₁ の１／２とし〔図１，図７（Ｃ）参照〕、さらに折しろ５₁ に較べ折しろ７Ａ₁ と７Ｂ₁ の幅を狭くして巻込み力と反発力を強め、横内底板１７Ａ₃ ，１７Ｂ₃ と内底板２７との嵌合部分２７ａと１７ａ，２７ｂと１７ｂに、前記反発力を強い嵌合力に変えて働かしめる。
【００５１】
しかし、フラップ８ＡＡ，２６ＡＡ，２８ＡＡの長さを図７（Ｄ）に示すように、いずれかのフラップ８ＡＡ₁ ，２６ＡＡ₁ ，２８ＡＡ₁ を材料から採りうる最大の長さとし相対する長さを短くし、かつ上・下で逆の構成として前記フラップ同士を突き合わせ重ねて巻込むとより抜けにくくなる、この構成は図７（Ａ）のフラップ４ＡＡと１４ＡＡ，４ＢＢと１４ＢＢに適用して、図７（Ｂ）のフラップ４ＡＡ₁ と１４ＡＡ₁ ，４ＢＢ₁ と１４ＢＢ₁ としてもよい。
【００５２】
上記のように横内底板１７Ａ₃ ，１７Ｂ₃ と内底板２７が嵌合した面に働く力は、既述のように嵌合部分が夫々台形１７ａ，１７ａと船底形２７ｂと２７ｂの形状をとることで、内底板２７が前外側板８と前内側板２８の折曲げ部分からくる反発力により後内側板２６側にずれようとする動きを効果的に阻止し、組立たあと身３は安定した形状を接着剤なしに維持することが可能である。
【００５３】
この様にして組立られたふた２と身３は共通の後外側板６と、横外側板４Ａ，７Ａの間と同様に横外側板４Ｂ，７Ｂの間に備えた図２の特殊ジョイント６Ａ，６Ｂとにより開閉可能な片開きの組立箱となるが、この特殊ジョイント６Ａ，６Ｂは左右対称であるため、特殊ジョイント６Ｂのみの動きを拡大図８（Ａ）から（Ｄ）により示し説明する。
【００５４】
図８（Ａ）は特殊ジョイント６Ｂで横外側板４Ｂ側に三角形６Ｂ₂ と横外側板７Ｂ側に四辺形６Ｂ₃ が設置され両者の間に三角形６Ｂ₁ が位置し、各形の境界には折曲げ用けい線６Ｂ₁₂，６Ｂ₁₃，６Ｂ₂₄，６Ｂ₃₇と三角形６Ｂ₁ の中程にも折曲げ用けい線６Ｂ₁₁が左右の辺に平行に刻まれている状態を表し、斜線を施した三角形６Ａ _４ ，６Ｂ _４ は切り抜き部分を示した。何れも各形の位置と各けい線の関係は図３と〔００１７〕項，〔００１８〕項の説明に従っている。
【００５５】
組立箱１はふた２が身３を完全に覆う構造なので、その展開図は図２に見られるように共通の後外側板６の形状が台形をなし、身３に対してふた２を被せるように動かすと、特殊ジョイント６Ｂの各けい線には組立箱１の内側に向く力が働き、図８（Ｂ）の閉状態では、先ずけい線６Ｂ₁₁が内向きに折れ、けい線６Ｂ₂₄，６Ｂ₃₇が外向きに折れ、次いでけい線６Ｂ₁₂が内向きに折れて三角形６Ｂ₁ がけい線６Ｂ₁₁を境にして約半分が捩じれるように曲がる。
【００５６】
図８（Ｃ）の更に進んだ閉状態では、けい線６Ｂ₁₁を境にした三角形６Ｂ₁ の約半分の折れ曲がりが三角形６Ｂ₂ の裏面に接合寸前まで進み、けい線６Ｂ₁₂が四辺形６Ｂ₃ の面に殆ど接する状態になり、けい線６Ｂ₁₃は外向きに折れ曲ってけい線６Ｂ₁₁とで小三角形を形成する。
【００５７】

The present invention relates to an assembly box having a buffer function for protecting bottles and the like from damage and a function for preventing tampering such as intentional attachment and removal of sealing paper.
[0002]
[Prior art]
Boxes for storing medical containers such as ampoules, vials, syringes, and drink bottles are generally manufactured separately on the lid and body, and a decorative frame is applied to the surface of the core material. After attaching the back and integrating it, a manufacturing method is adopted in which a partition and a cushioning material are inserted to make a finished product. However, since the number of parts required is extremely large, the work process leading to completion is also required. Many.

[Problems to be solved by the invention]
The biggest problem with boxes for pharmaceutical containers such as ampoules, vials, syringes, and drink bottles is that they are not damaged before the stored items in the box are used. The box made of a structure and material having an effective buffer function and strength has been sought, but no decisive thing has been made.
[0007]

Two triangles and a quadrilateral are connected to each other, and a special joint with a structure in which one triangle acts as two triangles by providing a folding threshold on each boundary and a folding threshold on the face of the triangle. Arranged,A punching material having a structure that suppresses the use of an adhesive material in which the lid and the body are integrated, and the punching materialInAn assembly box comprising assembly buffer means, falsification prevention means and partition material movement prevention means.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
As shown in the perspective view of FIG. 1, the names of the members of the assembly box are the front, side, and rear, with the open side when the assembly box in the half-open state is closed as the front, The bottom plate is divided and expressed by the combination of outside / inside and width, and the side plate and the flap are divided by the combination of outside / inside and height.
[0010]
The solution to the first problem is that a pulp made of an aggregate of fibers extracted from wood or other plants is selected as the material of the box as a target of the special paperboard. An intermediate product, which is a papermaking raw material that is made into a paper shape, and has the same basis weight, thickness and ultra-low density compared to the final product paper, so it is lightweight and soft, and stored in a roll that remains flat or wound. Is done.
[0011]
There are various types of pulp depending on the raw material, production method, application, etc., and to name a few, hemp pulp, linter pulp, straw pulp, wood pulp made from coniferous or hardwood, synthetic pulp, etc. There are mechanical pulp, kraft pulp, soda pulp, etc. by method, and dissolved pulp and paper pulp, etc. by application, but considering the versatility and price, paper pulp selected from kraft pulp and soda pulp made of wood is preferable. .
[0012]
Among the specifications for paper pulp, the basis weight is usually 40 to 300 g / m.², Preferably 100 to 275 g / m², More preferably 165 to 250 g / m²The thickness range is usually 0.2 to 1.5 mm, preferably 0.7 to 1.5 mm, more preferably 0.95 to 1.4 mm.
[0013]
Pulp is a safe material that has a small basis weight for its thickness as described above, so the whole is very flexible, and even if the punched material is folded and assembled manually, there is little risk of injury on the cut surface of the punched material. Even if the assembly box is no longer necessary, repulping (recycling) by melting is possible, and even in the combustion process, the furnace is not damaged or gives off an odor due to heat generation.
[0014]
The solution to the second problem is that the lid and the body are integrated from the first stage, except for parts that cannot be structurally integrated in the present invention, compared to the conventional method in which the lid and the body are separately manufactured and sequentially integrated. As an assembly box with a simplified structure, the number of punched materials and parts was reduced by pressing.
[0015]
Table 1 (B) and Table 2 (B) show the number of materials, the number of parts, and the finishing process of the parts constituting the assembly box according to this solution, and a method prior to the present invention is required. By comparing with the contents described in Table 1 (A) and Table 2 (A), it will be fully understood that the object has been sufficiently achieved.
[0016]
The assembly box of the present invention in which the lid and the body are integrated includes the following features.
1)When the lid is opened from the body, both the lid and the body are not opened to prevent the outer plate from opening more than 180 ° at the connection part and the outer plate that tends to occur when closing the lid from entering the inner plate. A special joint was installed between the lateral outer plates.
2)The side plate part and the ceiling plate part of the lid, the side plate part and the bottom plate part of the body, and the joint part (rear side plate) common to the lid and the body are all made of a double structure, and the repulsion of the double bent side plate is strong. The part of the wire was weakened as a lead wire with intermittent cuts made by a cutter.
3)The flaps between the side plates are also doubled (including the single portion), but a folding margin corresponding to the thickness of the double flaps is provided in connection with the side plate providing a gap for storing the flaps. It was assumed that it was a straight fold in the part that was not.
Four)In an integrated structure with a single material, the glued part was reduced only to the inside of both sides of the lid.
[0017]
As shown in FIG. 3, a special joint provided between the lateral outer plate connected to the ceiling plate of the lid and the lateral outer plate connected to the bottom plate of the body includes two sides of the height of both lateral outer plates and the ceiling plate. The quadrilateral portion formed by the height of the rear outer plate, which is a connecting portion sandwiched between the bottom plate and the bottom plate, is divided into a quadrilateral and three triangles by a folding line and a cutting line, and the connection is made from the division. The configuration is such that one triangle in contact with the end of the portion is removed.
[0018]
Of one triangle and two triangles, the height of the lateral outer plate connected to the outer ceiling plate of the lid is the one side of the first triangle, and the height of the lateral outer plate connected to the outer bottom plate of the body is One side of the quadrilateral, the remaining triangles are contiguously arranged between the two shapes, the point where the one quadrilateral and the two triangles intersect at one point is point e, and is sandwiched between the outer ceiling plate and the outer bottom plate The relationship of the intersection point f ′ between the normal line passing through the point e from the midpoint f of the height of the rear outer plate, which is the connecting portion, and the line segment ab ′ is as follows:
H = {height dimension of connecting portion + material thickness dimension × 2} × 0.55
By connecting the point e thus obtained and the vertices a, b, and c of each triangle and taking the angle ∠ aeg from the point e and the side ae at 90 °, the position of the point g on the side cd is determined. Bending lines ad, bc, ce, ef, and eg can be drawn sequentially.
[0019]
In the assembly box of the present invention, the side plate having the double structure is smoothly folded and the portion where the double or single flap is wound and fixed is 2 to 6 portions, and in principle, half of them are in a symmetrical positional relationship. The following dimension range is determined.
1)Of the double flaps to prevent the lids from opening easily on both sides, the height of the flaps on the inside is more than the height of the side plates connected to each other.₁(Material thickness) mm, t is the height of the outer flap₂Shorten by (material thickness + 0.5) mm.
2)Of the double flaps to prevent the front of the body from falling down (opening) easily, t is higher than the height of the side plate connecting the inner flaps.₁(Material thickness) mm, t is higher than the height of the side plate connecting the height of the flaps on the outside₂Shorten by (material thickness + 0.5) mm.
3)When the lid is opened, the height of the single flap connected to the rear side plate so that the contents do not move in the rearward direction of the body is set to be higher than the height of the side plate.₂Shorten by (material thickness + 0.5) mm.
[0020]
In order to relieve the repulsive force caused by the bending of the outer and inner plates, the overlapping part that accommodates the double flaps between the outer and inner plates has a folding margin equivalent to the thickness of the flaps. Preferably, the margin is the material thickness t₁It is selected and used according to the part of the assembly box from the range of 2 to 3 times, and the part that does not store the flap is directly folded, and the elastic material is self-compressed around the crease across the ridgeline. Increased, using the force, enhanced the locking effect of the fitting part placed first.
[0021]
The solution to the third problem greatly contributes to the effect that is born as a result of the solution to the first and second problems described above, but the process is integrated by integrating the lid and the body. As a result, the assembly box is almost an assembly of straight lines, making it easy to assemble even if it has a complicated shape.
[0022]
The effect of process integration is obtained by eliminating unnecessary processes and performing necessary processing intensively simultaneously or continuously. The state of the box finishing process by this solution is simplified. As shown in Table 2 (B), it becomes clearer by comparing with the contents of the finishing process described in Table 2 (A) required by the conventional method.
[0023]
When looking at the effects of this solution in terms of the number of boxes produced, either punching materials are used for mass production by automatic box making machines, or part of small volume production by manual assembly personnel by automating parts such as gluing. It is possible to dramatically increase the number of production per assembly staff compared to the conventional method.
[0024]
The solution to the fourth problem inevitably has a plate thickness from the standpoint of maintaining strength when using ultra-low density paper pulp, in addition to the effects of the solutions to the first and second problems described above. However, since the papermaking pulp retains a large amount of space in the gaps between the fibers, the buffer function of the assembly box can be greatly increased without increasing the weight.
[0025]
In addition, the entire assembly box has a double structure, and the flaps fixed between the outer and inner plates in front and side are also doubled, so in addition to the buffer function inherent to the paper pulp material itself already mentioned In addition, the presence of the air layer in the gap formed by the double structure has an interaction that further enhances the buffer function, and the double structure further increases the strength against the stacking of the assembly boxes, that is, the pressure resistance. .
[0026]
The solution to the fifth problem is a significant contribution of the effect of the solution to the fourth problem described above, and a marked increase in the buffer function is easily broken such as ampoules, vials, syringes, drink bottles, etc. The impact force received during automatic filling is well absorbed, and the pressure resistance of the assembly box is improved, making it possible to attach to an automatic filling machine.
[0027]
The solution to the sixth problem is that in a normally open box, the container is stored and then the lid is closed, and a sealing paper is used at the joint with the body, but the assembly box is made of paper pulp, When the attached sealing paper is once peeled off, the surface of the papermaking pulp is peeled off while adhering to the sealing paper, and the sealing paper has a characteristic that it cannot be attached unless glue is used again.
[0028]
Moreover, the assembly box according to the present invention has a preferable length in the range of 2/5 to 1/2 of the front width of the lid so that the polymerization (abutment) portion does not open by opening and closing the lid. Once assembled, the box cannot be easily dismantled without damage, so it is difficult to reuse the dismantled product after dismantling, and fraudulent acts including tampering with the sealing paper and reuse of the discarded product, that is, falsification. This is a function that cannot be obtained with a conventional hard paper box using short flaps.
[0029]
Even if the length of the flap wound on the lateral and inner plates of the rectangular assembly box is 1/2 of the lid width, the ratio of the length and height of the flap may be smaller than that of the lid. As long as one of the left and right double flaps is long and the other is short within the range that can be measured from the pulp for papermaking, the upper and lower flaps are reversed and the flaps are overlapped. The flap is more difficult to remove.
[0030]
It will be understood that all of the above-mentioned solutions included in the present invention are accompanied by extremely great effects, and the pulp is colored before and after plate formation, and is printed before and after punching or after assembly. In addition to the possibility, the entire assembly box has a structure that requires as little glue as possible when assembling each part.
[0031]
Table 1 (A, B) shows the unit weights of the materials used for the box made by the conventional method and the assembly box made by the present invention. The boxes made using these materials The total weight of the latter is small, about 70% of that of the former. In addition, the latter is overwhelmingly superior to the former in terms of the labor required for production and the shock-absorbing function or price of the product. Only.
[0032]
Papermaking pulp has a large number of fine openings on its surface and a large number of spaces on its inner surface, so that it has high liquid permeability. Conventional glue (main component: acrylic vinyl acetate copolymer resin, viscosity 10) , 12,000 to 12,000 cps (concentration 50 to 60%), the adhesive is not sufficient, and the initial adhesive strength is strong and stable. [(Main component: Special copolymer vinyl resin / viscosity 14,000 to 16, 000 cps / concentration 50-60%), for example, Direct Bond VK-10 manufactured by Hiranoya Corporation is preferred].
[0033]
The papermaking pulp to be used is in the stage of paper making process to make a plate, and the internal fibers can be oriented, so when decorative paper is not used on the outer surface of the assembly box, the external fibers act on the assembly box to apply the fibers. However, this phenomenon itself does not impair the strength, buffer function, and commerciality of the assembly box.
[0034]
The function of the assembly box according to the present invention is that the papermaking pulp itself has the softness and cushioning function, and the lid and body integrated structure, which is a countermeasure for production of the assembly box, and the double structure, which is a countermeasure for strength. As a result of improving the production efficiency of the assembly box and maintaining a high pressure strength and a high buffering function, it is possible to automatically fill a medical container that is easily broken.
[0035]

【The invention's effect】
The following effects were obtained by using the assembly box according to the present invention.
1)Since a very low density material and strong adhesive type sealing paper were used, peeling off the sealing paper also caused the material skin to adhere and peel at the same time, making it difficult to reuse the sealing paper, and the assembly box was integrated By extending the length of the flap with a double structure, an assembly box with a so-called falsification prevention measure that is difficult to dismantle without being damaged by using a minimum amount of glue was completed.
2)The ultra-low density material and the double structure have greatly enhanced the buffer function and improved the pressure resistance, which greatly increases the possibility of reliably preventing accidents such as damage to the contents caused by the assembly box.
3)The packaging box's cushioning function and improved compressive strength enable automatic filling of fragile pharmaceutical containers with machines.
4) Productivity has been greatly improved by the integrated structure of the assembly box.
Five)1.4 mm thick paper pulp (250 g / m²) Is the same thickness of paperboard (1250 g / m²) Was 1/5 of the weight, which helped to reduce the weight of the assembly box.
6)Papermaking pulp is an intermediate product and is low in price, and has expanded the range of waste disposal methods such as reuse (recycling) and incineration after use, which has helped to reduce the total cost from material procurement to product disposal. .
