Description

【０００１】
【産業上の利用分野】
本発明は、ガラス基板（素板ガラス、液晶表示用ガラス基板、プラズマ表示体用ガラス基板、蛍光表示管、サーマルヘッド用ガラス基板、有機ＥＬ基板、カラーフィルター等）、ハイブリッドＩＣ用セラミックス基板、ウエハ、薄膜トランジスタ形成済みのガラス基板、液晶セル、回路を組み込んだガラス基板などの各種ガラス基板又はこれらのガラス基板を用いて製造した完成パネルなどのガラス基板等のガラス基板を搬送するためのガラス基板搬送用ボックスに関するものである。
【０００２】
【従来の技術】
カラー液晶表示装置用のカラーフィルター、プラズマ表示体用ガラス基板、蛍光表示管、サーマルヘッド用ガラス基板、有機ＥＬ基板又はカラーフィルター等のデバイスメーカーにおけるガラス基板（完成パネルを含む）の搬送のために、ＡＢＳ樹脂、ポリ塩化ビニルをはじめとする種々の樹脂の射出形成体やその組立品からなるガラス基板搬送用ボックスが使用されている。しかし、これらの搬送用ボックスは、比較的重く、しかも衝撃を和らげる性質に乏しいために、破損し易いガラス基板を収容して、移動、積み重ね及び輸送する上で扱い難い。そこで、これらの搬送用ボックスに代えて、発泡ポリエチレンや発泡ホリプロピレン製のガラス基板搬送用ボックスが使用されている。
【０００３】
【発明が解決しようとする課題】
液晶表示装置の大型化などにより、ガラス基板は大型化しており、これに伴って、ガラス基板搬送用ボックスは、大型化し、高価なものとなっている。また、ガラス基板の大型化は、ガラス基板を、小形のガラス基板に比して撓み易くなり、搬送時に破損し易くなって問題である。また、ガラス基板搬送用ボックスにおいて、ガラス基板を収容する本体部及び蓋体部は、ガラス基板の収容を確実にするために、寸法安定性の良い発泡プラスチックで作製されている。しかし、ガラス基板は、表面が平滑に形成されており、表面の僅かな汚れ、傷、泡及び粉塵等の微細な異物の付着も問題とされるので、ガラス基板搬送用ボックス内における粉塵の発生を避けるために、精密に形成されており、寸法安定性の良い発泡プラスチックで作製されている。しかし、寸法安定性の良い発泡プラスチックは、比較的硬質であるので、寸法安定性の良い発泡プラスチックのみでガラス基板を保持するのでは、搬送時の僅かな衝撃によってもガラス基板が破損して問題である。そこで、永久歪が小さく弾性に富む発泡プラスチック製の溝付きのガラス基板押さえ部材、即ち、パッドを、本体部の底部及び蓋体部の天井部の内面に取外し可能に設けて、ガラス基板の端部を支持することにより、ガラス基板への衝撃を緩和している。しかし、このパッドも発泡成形により製造されており、ガラス基板搬送用ボックスの金型に加えてパッドの金型も必要となり、金型の作製に多くの費用を要して問題である。
本発明は、従来の発泡プラスチック製のガラス基板搬送用ボックス内のガラス基板支持に係る問題点及びガラス基板搬送用ボックスの大型化に伴うガラス基板の搬送に係る問題点を解消することを目的としている。
【０００４】
【課題を解決するための手段】
本発明は、廉価なガラス基板押さえ部材、即ちパッドを提供すると共に、該パッドのガラス基板搬送用ボックス底部への取付けを容易にし、ガラス基板の上下端部の該ガラス基板搬送用ボックスの底部及び蓋体部の天井部への保持を正確にし、また、ガラス基板、特に大型ガラス基板端部の一様な弾性保持を可能にして、且つガラス基板、特に大型ガラス基板の安全な搬送を可能にしたガラス基板搬送用ボックスを提供することを目的としている。
【０００５】
即ち、本発明は、上部開放の有底の発泡プラスチック製の本体部及び該本体部の上部を覆う発泡プラスチック製の蓋体部を備えるガラス基板搬送用ボックスにおいて、本体部は、側壁部と底壁部とで形成されており、相対する少なくとも一組の側壁部は、内面にガラス基板保持用の溝が形成されており、該側壁部下端に連設し、且つ内面に前記相対する側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出して凸条部が形成されており、この凸条部の夫々の上面には、前記相対する側壁部の対応するガラス基板保持用の溝を結ぶ方向に、ガラス基板支持用の溝が形成されており、各対の凸条部間には、発泡プラスチックに比して弾性に富むガラス基板押え部材が保持されていることを特徴とするガラス基板搬送用ボックスにあり、また、本発明は、上部開放の有底の発泡プラスチック製の本体部及び該本体部の上部を覆う発泡プラスチック製の蓋体部を備えるガラス基板搬送用ボックスにおいて、本体部は、互いに継合部を備えて継合する第一本体部材と第二本体部材を備えており、第一本体部材及び第二本体部材は、夫々、端部側壁部と、前記端部側壁部に側部で連接する側壁部と、前記端部側壁部及び側壁部に夫々の下端部で連接する底壁部とを備えており、第一及び第二本体部材の端部側壁部には、夫々その内面に、互いに対応するガラス基板保持用の溝が形成されており、第一及び第二本体部材の底壁部には、前記相対する第一及び第二の本体部材の端部側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出る複数対の凸条部が形成されており、該凸条部は、前記相対する第一及び第二本体部材の端部側壁部の対応するガラス基板保持用の溝を結ぶ方向に、ガラス基板支持用の溝が上面に形成されており、各対の凸条部間には、前記発泡プラスチックに比して弾性に富むガラス基板押え部材が保持されていることを特徴とするガラス基板搬送用ボックスにあり、さらに、本発明は、上部開放の有底の発泡プラスチック製の本体部及び該本体部の上部を覆う発泡プラスチック製の蓋体部を備えるガラス基板搬送用ボックスにおいて、本体部は、夫々、継合部を備える有底の第一本体部材、第二本体部材及び第三本体部材を備えており、第三本体部材は前記第一及び第二本体部材の間に位置するものであり、本体部は第三本体部材の両側の継合部を対応する第一本体部材及び第二本体部材の継合部に継合して形成されており、第一及び第二本体部材は夫々、端部側壁部と、前記端部側壁部に側部で連接する側壁部と、前記端部側壁部及び側壁部に夫々の下端部で連接する底壁部とを備えており、第三本体部材は、底壁部及び底壁部の両側部に立設されている側壁部を有しており、底壁部及び側壁部の両端部に夫々設けられている継合部を介して、夫々対応する第一及び第二本体部材の底壁部及び側壁部に継合しており、第一及び第二本体部材の端部側壁部は、夫々その内面に、互いに対応するガラス基板保持用の溝が形成されており、第一、第二及び第三の本体部材の底壁部には、前記相対する第一及び第二の本体部材の端部側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出る凸条部が形成されており、該凸条部は、前記相対する第一及び第二本体部材の端部側壁部の対応するガラス基板保持用の溝を結ぶ方向に、ガラス基板支持用の溝が上面に形成されており、対となる凸条部間には、前記発泡プラスチックに比して弾性に富むガラス基板押え部材が保持されていることを特徴とするガラス基板搬送用ボックスにある。
【０００６】
【発明の実施の形態】
本発明において、ガラス基板搬送用ボックスの本体部（以下、本体部という）は、本体部に収容されるガラス基板保護のためのクッション性の付与及び断熱性の付与のために、発泡倍率が３乃至３０倍、好ましくは発泡倍率で４乃至２５倍のポリオレフィン系発泡体により製造することができる。このポリオレフィン系発泡体としては、ポリエチレン発泡体、ポリプロピレン発泡体、ポリスチレン発泡体、ポリエチレン−ポリスチレン共重合体の発泡体又はこれらのポリマーブレンドの発泡体などがある。本発明において、特に、ポリオレフィン発泡体として、例えば、ビーズ成形発泡によるポリエチレン・ポリスチレン共重合樹脂発泡体、ビーズ成形発泡によるポリエチレン発泡体、ビーズ成形発泡によるポリスチレン発泡体及ビーズ成形発泡によるポリプロピレン発泡体を使用することができる。
【０００７】
本発明においては、ガラス基板搬送用ボックスの蓋体部（以下、蓋体部という）は、本体部と同様に発泡プラスチック成形体とすることができる。この場合、本体部と蓋体部は、同一の素材で形成するのが好ましい。しかし、蓋体部は、透明又は不透明樹脂成形体とすることができる。また、本発明において、本体部の色調と蓋体部の色調を相違させて、本体部と蓋体部の境を明確にし、蓋体部を本体部と、また本体部の部分を蓋体部の部分と誤ることがないようにすることができる。
【０００８】
本発明において、本体部は、側壁部と底壁部とで連続して一体又は組立式に形成することができる。この場合、本体部の底壁部は、周辺端部から連続して、側壁部を立設しており、底壁部の内面には、前記本体部の相対する端部側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出して凸条部が形成されている。本発明において、蓋体部は、側壁部と天井壁部とで連続して一体に形成することができる。この場合、蓋体部の天井壁部は、周辺端部から連続して、側壁部を垂下しており、天井壁部の内面には、前記本体部の相対する端部側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出して凸条部が形成されている。この凸条部の夫々の面には、前記本体部の相対する側壁部の対応するガラス基板保持用の溝を結ぶ方向に、ガラス基板保持用の溝が形成されており、該溝は、ガラス基板端部を該溝内に保持可能に形成される。各対の凸条部間には、ガラス基板押え部材を保持可能とするために、ガラス基板押え部材挿着用の窪んだ空間が形成され。このガラス基板押え部材挿着用の窪んだ空間は、該空間内に、ガラス基板押え部材を装着して、ガラス基板をガラス基板搬送用ボックス内に保持させたときに、該ガラス基板押え部材により、ガラス基板の端部の弾性保持を可能にする。
【０００９】
本発明において、本体部へのガラス基板押さえ部材の取付けを容易にするために、本体部を底部付きの二つの本体部材で形成する場合には、ガラス基板押さえ部材の取付けが容易となるように、一方の底部付き本体部材の側壁部の少なくとも一部を、低く形成することができる。この場合、低く形成された側壁部の上に継足し側壁部を取付けて、もう一方の底部付き本体部材の側壁部と高さを合わせることが出来る。また、この場合、片方の底部付きの本体部材の長さを変えることにより、所望の長さに本体部を形成することができる。また本体部を底部付きの三つの本体部材に分けて組立て形式で形成する場合には、両端部の底部付きの本体部材を同一の長さに形成し、中間の底部付きの本体部材の長さのみを変えることにより、所望の長さの本体部を形成することができる。また、一方の端部の底部付きの本体部材の長さを変えることにより、所望の長さの本体部を形成することができる。このように、本体部を底部付きの三つの本体部材に分けて組立て形式で形成する場合においても、底部付きの三つの本体部材の中の一つの本体部材の側壁部、例えば、中間の底部付きの本体部材の側壁部を、ガラス基板押さえ部材の取付けが容易となるように、低く形成することができる。この場合、低く形成された側壁部の上に継足し側壁部を取付けて、他の底部付き本体部材の側壁部と高さを合わせることが出来る。
【００１０】
このように、本体部を二以上の即ち複数の底部付きの本体部材の組立て形式に形成すると、成形される本体部用の個々の底部付きの本体部材を小形とすることができ、大型の成形装置を使用しないで大型の本体部を成形により形成することができる。そして、本発明は、本体部及び蓋体部を組立て形式の部材とすることができるので、大型のガラス基板搬送用ボックスを、高価な大型成形装置を使用しないで、成形により形成することが容易となる。しかも、両端部の本体部材及びそれらの間に位置する両端部の本体部材又は中間の本体部材で本体部を形成する場合は、これらの中の少なくとも一つの本体部材の側壁部の高さを低く形成し、継足し側壁部により高さを調整して、大型のガラス基板搬送用ボックス用の本体部内にガラス基板押さえ部材を比較的簡単に取付けることができるので、ガラス基板の大きさの変化に追随でき、ガラス基板押さえ部材の取付けにも支障をきたさない。
【００１１】
本発明において、垂直の用語は、垂直及び許容される範囲で略垂直であることを意味する。本発明において、連接とは、部分が他の部分と一体に連続していること又は連続して一体に接続していることを意味する。本発明において、本体部を前記第一及び第二の本体部材で形成される場合には、第一本体部材の側壁部は、夫々対応する第二本体部材側壁部に継合し、第一本体部材の底壁部は、夫々対応する第二本体部材底壁部に継合するように、夫々の端部には、継合部が形成されている。本発明において、継合部は、互いに継ぎ合う部分であり、継ぎ手構造に形成され、雇核接、核接又はほぞ接などの継ぎ手構造とすることができる。本発明において、前記第一及び第二の本体部材は、夫々、互いに対応する第一及び第二の両側壁部及び底壁部の継合側端部の継合部を介して取外し可能に継合でき、さらに、継合部は、内側及び外側に締結部材を配置して本体部材同士の継合を確実にすることができる。
【００１２】
本発明において、本体部を底部付きの三つの部材に分けて組立て形式に形成する場合には、前記第一及び第二本体部材は、共に、ガラス基板保持用の溝を有する端部側壁部と、該端部側壁部の両側部から、連続して垂直に延び、互いに並行に形成されている両側壁部と、前記端部側壁部の底部及び両側壁部の底部を繋いで形成されている底壁部を備えている。前記中間の本体部材は、底壁部と、該底壁部から平行に立上り、一体に形成される側壁部とを備えている。中間の本体部材の側壁部は、一方の側で、対応する第一の本体部材の第一側壁部に継合し、他方の側で対応する第二の本体部材の第二側壁部に継合するように、夫々の側に継合部が形成されている。また、中間の本体部材の底壁部は、一方の側で、対応する第一の本体部材の第一底壁部に継合し、他方の側で対応する第二の本体部材の第二底壁部に継合するように、夫々の側には継合部が形成されている。この場合においても、継合部は、例えば、ほぞ接ぎや核接ぎ等の前記継ぎ手構造に形成される。この場合においても、中間の本体部材は、第一の本体部材及び第二の本体部材に、側壁部及び底壁部の継合部を介して取外し可能に継合して、本体部を形成するが、継合している箇所には、内側及び外側に締結部材を配置して本体部材同士の継合を確実にすることができる。本発明において、中間の本体部材は、中間側壁部を上下に分割して組立て形式のものとすることができる。本発明において、底壁部には、組立形式又は非組立形式に拘わらず、その内面に、前記相対する側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出して凸条部が形成されており、この凸条部の夫々の上面には、前記相対する側壁部の対応するガラス基板保持用の溝を結ぶ方向に、ガラス基板保持用の溝が形成されており、各対の凸条部間には、ガラス基板押え部材が保持される。
【００１３】
本発明において、ガラス基板搬送用ボックスは、被せ蓋の箱に形成され、被せ蓋の箱本体に被せる形式には、▲１▼　本体側壁部の開放頂部外側に断面切欠き状に形成された切欠き状部を有し、前記開放頂部内側に切り欠き残部の係合凸壁部を有しており、蓋体側壁部下部の内面が、係合凸壁部の外側側面部に継合する構造の所謂本印篭型の形式と、▲２▼本体部において，側壁部の開放頂部内側に、段欠き部、即ち断面切欠き状に形成された切欠き状部を備え、前記開放頂部外側に切り欠き残部の係合凸壁部を備え、被せ蓋の蓋体側壁部下部の外面部が、本体部の係合凸壁部の内側側面部に係合する構造の所謂逆印篭型の形式とがある。一般には、ガラス基板搬送用ボックスは、本印篭型の被せ蓋の箱に形成される。本発明において、ガラス基板搬送用ボックスが本印篭型の被せ蓋の箱とする場合には、蓋体部が被せられる本体部の側壁部の頂部開放部には、その外側部分に断面切欠き状に切欠き状部が形成され、また、その内側部分に切欠き残部として立設される凸壁部、即ち、係合凸壁部が形成される。また、本体部の側壁部の頂部開放部の断面切欠き状に形成された切欠き状部の外側部分の少なくとも一部に、蓋体部の取外しが容易に行えるように、指等が差込可能な、溝又は穴等の窪み部を形成することができる。さらに、本発明においては、前記本体部材の側壁部外面には、継合部及び隅部の補強のために、また、側壁部の反り又は変形を極力避けるために、継合部、角部、上端部及び下端部に肉厚部が形成される。本発明において、ガラス基板搬送用ボックスが本印篭型の被せ蓋形式の箱である場合は、蓋体部は、本体部の上端開放部を覆い、さらに蓋体部の側壁部下部は、前記本体部の係合凸壁部の外側面部を覆うように形成される。しかし、蓋体部の側壁部下部を、係合凸壁部から、さらに本体部の上部側壁部にまで延長して、本体部の上部の外面形状に倣って形成することができる。
【００１４】
本発明のガラス基板搬送用ボックスにおいて、本体部を形成する各本体部材は、発泡倍率が、３〜３０倍、好ましくは発泡倍率が４乃至２５倍の単一のポリオレフィン系発泡成形体により製造されるが、本体壁部の内面から１ｍｍ以下の深さに至る部分が、該側壁部の中央部の密度よりも１．５倍以上大きい密度のスキン構造とすることが好ましい。本発明において、ガラス基板搬送用ボックスの本体部は、相対する少なくとも一組の本体部材の端部側壁部内面に、ガラス基板の端部保持用の溝が形成されており、ガラス基板は前記溝内に端部が支持されて、本体部に収容される。本発明においては、本体部は、各本体部材を組み立て式に構成することができるが、この場合においても、一体成形体の発泡体と同様に、クッション性及び断熱性を有し、ガラス基板に対して外部から加えられる衝撃及び熱を緩和でき、衝撃及び熱によるガラス基板の変形及び破損等を防止することができる。
【００１５】
また本発明において、各本体部材の底部及び蓋体部材の天井部には、前記相対する少なくとも一組の本体部材の端部側壁部内面に形成されているガラス基板の端部保持用の溝の対応する溝を結ぶ方向に交差する方向に、少なくとも一対の、好ましくは複数対の凸条部が形成されており、該凸条部は、ガラス基板押さえ部材を保持するための少なくとも一対の、好ましくは複数対の凸条部が形成されており、該凸条部の上面には、前記溝を結ぶ方向に、ガラス基板の頭部及び底部保持用の溝が形成されている。本発明において、対となる凸条部の間には、ガラス基板押さえ部材、即ち、パッドを設けることができる。本発明において、ガラス基板押さえ部材、即ちパッドは、従来のパッドと相違して、ガラス基板端部保持用の溝が形成されておらず、ガラス基板端部に接触する面は、平坦な面又は疎面にすることができる。疎面とする場合には、その凹凸の大きさは、ガラス基板を、ガラス基板押え部材に安定して支持できる大きさであり、例えば、浅い凹凸であり、ガラス基板の厚みの１／３以下、好ましくは１／５以下の大きさの細かく浅い凹凸にすることができる。このように本体部材の底部内面及び蓋部材の天井壁部内面に、平坦な面又は疎面が形成されているパッドを設けることにより、ガラス基板は、その端部が、対となる凸条部上面の溝内に差込まれて、位置が保持され、パッド面上でガラス基板の端部は弾性保持される。このようにガラス基板は比較的柔らかく弾性保持されるので、ガラス基板搬送用ボックス内に配置されたガラス基板を、搬送過程において安定させることができる。
【００１６】
本発明において、各継合部に締結用突出部を形成して、継合時には、継合箇所で両継合部の締結用突出部同士が並び、断面コの字形の締結部材等の締結部材により、締結用突出部を挟持させて、継合部の継合を確実にすることができる。この継合部に形成される突出部は、本体部の側壁部の表側及び裏側に溝を形成し、該溝内に形成すると、突出部及び締結部材が外側及び内側の面の外に突き出ないので好ましい。このように取付けられた締結部材が簡単に脱落しないように、突出部及び締結部材にピン又はネジ等の固定具挿通用の孔を形成し、この締結部材を突出部の上に、夫々の固定具挿通用の孔を整合して配置し、ピン又はネジ等の固定具を挿通して、締結部材を突出部に固定するのが好ましい。本発明において、締結部材は、例えば、透明又は不透明な合成樹脂製とすることができる。このような合成樹脂製のものとしては、例えば、アクリロニトリル・ブタジエン・スチレン樹脂（ＡＢＳ）、ポリエチレンテレフタレート（ＰＥＴ）、ポリブチレンテレフタレート（ＰＢＴ）、高分子量ポリエチレンなどの単体よりなる成形体、又はこれらの二種以上で形成される積層体とすることができ、また、シート状、板状、柱状若しくは筒状などの形状を有する成形体又は積層体とすることができる。
【００１７】
本発明において、本体部は、上部開放の有底の発泡プラスチック製の本体部及び該本体部の上部を覆う発泡プラスチック製の蓋体部を備えるガラス基板搬送用ボックスにおいて、本体部は、互いに継合部を備えて継合する第一本体部材と第二本体部材を備えており、第一本体部材及び第二本体部材は、夫々、端部側壁部と、前記端部側壁部に側部で接続する側壁部と、前記端部側壁部及び側壁部に夫々の下端部で接続する底壁部とを備えており、第一及び第二本体部材の端部側壁部には、夫々その内面に、互いに対応するガラス基板保持用の溝が形成されており、第一及び第二本体部材の底壁部には、前記相対する第一及び第二の本体部材の端部側壁部の対応するガラス基板の端部保持用の溝を結ぶ方向と交差する方向に、夫々、内側に突出る複数対の凸条部が形成されており、該凸条部は、前記相対する第一及び第二本体部材の端部側壁部の対応するガラス基板保持用の溝を結ぶ方向に、ガラス基板保持用の溝が上面に形成されており、各対の凸条部間には、ガラス基板押え部材が保持されているので、分解可能に本体部材を組立てることができ、ガラス基板押さえ部材の取付けが、ガラス基板搬送用ボックスが大型化しても、簡単且つ容易に行うことができる。

【００１９】
図１乃至図４に示す実施例において、ガラス基板搬送用ボックス１は、本体部２と蓋体部３で形成されている。本例において、本体部２は、互いに対向する両端部に、夫々、ガラス基板保持溝部４を有するガラス基板保持部５を一体に備える端壁部６を有し、夫々その両側に、側壁部７を有し、下部に底壁部８を有して一体に形成されている。本例において、端壁部６に形成されているガラス基板保持部５には、複数の凸条部９が形成され、該凸条部９の間はガラス基板保持溝ガラス基板保持溝部４となっている。ガラス基板保持溝部４は、ガラス基板１０の側部端部が挿着できる幅で、上端から下端に形成されている。本例においては、ガラス基板１０の側部端部がガラス基板保持溝部４内に挿着されたときに、ガラス基板１０の下端部１１が安定して支持されるように、底壁部８には、側壁部７の内面を結ぶように、底壁部８の内面上から一個ずつ立上って形成される複数の凸部１２が並設されており、それら凸部１２の間で底壁部８の面上に形成される空間は、ガラス基板挿着用の溝部空間１３となっている。本例において、所定の間隔をおいて設けられている凸部１２の列で凸条部１４は形成されている。（図３参照）。本例において、凸条部１４は、二列の凸条部１４が一組となるように形成されており、一組の凸条部１４の間には、ガラス基板押え部材１５の装着用の窪んだ空間１６となっている。

図４に示すように、一組の凸条部１４の対向する側、つまり内側側部の一方の側壁部側の端部には、ガラス基板押え部材１５の位置決め用の凹部１７が形成されている。この凹部１７にガラス基板押え部材１５が嵌合可能であるように、ガラス基板押え部材１５の両側端部には、この凹部１７に対応する箇所に、外側に突き出た嵌合用凸部１８が形成されている。ガラス基板押え部材１５には、さらに、弾性嵌合用の凸部１９が形成されており、このガラス基板押え部材１５の弾性嵌合用の凸部１９を凸条部１４に弾性嵌合するように、該弾性嵌合用の凸部１９に対応する箇所の凸条部１４の凸部１２の下部には、ガラス基板押え部材弾性嵌合用の凹部２０が形成されている。本例において、ガラス基板押え部材１５は、蓋体部３の天井部２１の内側にも、本体部２の底部８の内側と同様に、天井部と一体に複数の凸部１２を並設して、夫々の凸部間にガラス基板挿着用の溝部１３が形成されている凸条部１４が、二つ凸条部１４を一組として、複数組設けられている。
【００２１】
本例は、以上のように構成されているので、本体部２の底壁部８に一体に形成されている夫々の組の凸条部１４間に、ガラス基板押え部材１５を装着する。ガラス基板押え部材１５の装着は、先ず、凸条部１４のガラス基板押え部材１５の位置決め用の凹部１７に、ガラス基板押え部材の位置決め用の凸部１８を嵌め込み、ついで、ガラス基板押え部材１５を、ガラス基板押え部材１５の装着用の窪んだ空間１６内に上から押し込み、ガラス基板押え部材１５の弾性嵌合用の凸部１９を、凸条部１４の凸部１２の下部に形成されているガラス基板押え部材１５の弾性嵌合用の凹部２０に嵌合して行われる。
【００２２】
蓋体部３の天井壁部２１においても、本体部２の底壁部８の場合と同様に、二つ一組で複数組の凸条部１４は、天井部と一体に形成されており、夫々の組の凸条部１４間には、ガラス基板押え部材１５が装着される。このようにして、本体部２及び蓋体部３には、夫々ガラス基板押え部材１５が装着される。このガラス基板押え部材１５が装着された本体部２に、ガラス基板１０が装着される。ガラス基板１０の本体部２への装着は、ガラス基板保持部材１０の両側部を、本体部２の夫々両端壁部６のガラス基板保持部５のガラス基板保持溝部４内に差込んで、その儘、該溝部４内を下方に移動させて、ガラス基板１０の下端部１１を、底壁部８に一体に形成されている凸条部１４のガラス基板挿着用の溝部１３に差込んで取付けることによって行われる。このようにガラス基板１０が、ガラス基板搬送用ボックス１の本体部２に装着されたところで、その上に、凸条部１４間にガラス基板押え部材１５が装着されている蓋体部３をガラス基板の差込位置を合わせて被せ、ガラス基板１０をガラス基板搬送用ボックス１内に装着する。
【００２３】
図５における実施例においても、図１乃至図４に示す実施例と同様に、ガラス基板搬送用ボックス１は、本体部２と蓋体部３で形成されている。しかし、本例は、図１乃至図４に示す実施例とは、本体部２が分割されて、組立形式に形成されている点で相違している。本体部２は、互いに対向する両端部に、夫々、ガラス基板保持溝部４を有するガラス基板保持部５を有する有底の二つの本体第一及び第二端部部材２２及び２３を備える。本例において、ガラス基板保持部５の複数のガラス基板保持溝部４は、例えば複数ガラス基板が収まるように、水平方向の断面形状で波形等の連続する凹凸形状に形成されている。ガラス基板搬送用ボックス１の本体部２は、有底の本体端部部材２２及び２３の間に、本体中間側部部材２４及び２５並びに有底の本体中間底部部材２６を備えて一体に形成されている。
【００２４】
本体第一及び第二の端部部材２２及び２３は、夫々、ガラス基板保持部５を有する端部端壁部２７と、該端部端壁部２７の両側の端部から夫々平行に突出る二つの端部側壁部２８（図中手前側の側壁部）及び２９（図中向こう側の側壁部）と、前記端部端壁部２７の底部の夫々から、前記端部側壁部の底部に連なって突出る端部底壁部３０とで形成されている。
【００２５】
本例において、本体第一端部部材２２及び２３の両端部側壁部２８及び２９の側部開放側端部には、夫々、上方に端部側壁部上部継合部３１及び３４が設けられ、下部に端部側壁部下部継合部３２及び３５が設けられており、本体第一端部部材２２の端部底壁部３０の端部には、本体第一端部部材底壁部継合部３３が設けられている。本体第二端部部材２３は、本体第一端部部材２２と同様に形成されており、本体第二の端部部材２３の両端部側壁部２８及び２９の側部開放側端部には、上方に端部側壁部上部継合部３１及び３４が設けられ、下部に側壁部下部継合部３２及び３５が設けられており、本体第二の端部部材２３の端部底壁部３０の端部には、本体第二端部底壁部継合部３６が設けられている。本体第一及び第二の端部部材２２及び２３に継合する本体中間側部部材２４（図中手前側の本体中間側部部材）には、第一及び第二の端部側壁部２８の上部継合部３１に継合可能とするために、継合部３７が設けられており、本体第一及び第二の端部部材２２及び２３に継合する本体中間側部部材２５（図中向こう側の本体中間側部部材）には、第一及び第二の端部側壁部２９の上部継合部３４に継合可能とするために、継合部３８が設けられている。本体中間側部部材２４の下端部には、本体中間底部部材２６の底部側壁部３９に継合可能とするために、中間側部下端継合部４１が設けられている。本体中間側部部材２５の下端部には、本体中間底部部材２６の底部側壁部４０に継合可能とするために、中間側部下端継合部４２が設けられている。これに対応して、本体中間底部部材２６の両中間底部側壁部３９を、本体中間側部部材２４の中間側部下端継合部４１に継合可能とするために、本体中間底部部材２６の両中間底部側壁部３９の上端部には、中間底部側壁部上端継合部４３が設けられており、また同様に、本体中間底部部材２６の両中間底部側壁部４０を、上端部本体中間側部部材２５の中間側部下端継合部４２に継合可能とするために、本体中間底部部材２６の両中間底部側壁部４０の上端部には、中間底部側壁部上端継合部４４が設けられている。
【００２６】
本例において、本体中間底部部材２６を本体端部部材２２及び２３に継合可能にするために、本体中間底部部材２６の中間底部側壁部３９の両側の側部端には、端部側壁部下部継合部３２に継合可能の中間底部側壁部側部継合部４５が設けられており、また、本体中間底部部材２６の中間底部側壁部４０の両側の側部端には、端部側壁部下部継合部３５に継合可能の中間底部側壁部側部継合部４６が設けられている。本体中間底部部材２６を本体端部部材２２及び２３の底部に継合可能にするために、本体中間底部部材２６の中間底部底壁部４７には、本体第一端部部材２２の端部底壁部継合部３３に対応する側に、端部底壁部継合部３３に継合可能の中間底部底壁部側部継合部４８が形成され、本体第二端部部材２３の端部底壁部継合部３６に対応する側に、端部底壁部継合部３６に継合可能の中間底部底壁部側部継合部５０が形成されている。本例において、各継合部は、夫々一組の継合部で形成されており、その一方の継合部にはホゾが形成され、他方の継合部にはホゾ穴が形成されており、所謂ホゾ継手を構成している。本例においては、本体第二端部部材２３の端部底壁部継合部３６には、ホゾ穴４９が形成され、これに継合する側の中間底部底壁部側部継合部５０には、ホゾ５１が形成されている。
【００２７】
本例において、本体端部部材２２及び２３の端部底壁部３０並びに中間底部部材２６の中間底壁部４７の内側には、ガラス基板挿着用の溝部１３が形成されている凸条部１４が、二条一組で複数組形成されており、該突条部１４間には、ガラス基板押え部材１５の装着用の窪んだ空間１６が形成されている。蓋体部３の天井壁部２１の内面には、本体部２の底壁部２６の内面と同様に、ガラス基板挿着用の溝部１３を有する凸条部１４が、二条一組で複数組形成されており、該凸条部１４間には、ガラス基板押え部材１５の装着用の窪んだ空間１６が、ガラス基板押え部材１５を装着可能に形成されている。本例において、本体部２の側壁部２７には、本体部２に被せられた蓋体部３を本体部２から取外す為の指入れ用の窪み５２が形成されている。
【００２８】
本例において、本体部２に蓋体部３を被せたときに、蓋体部３が本体部から容易に離脱しないように、蓋体部３は印籠蓋に形成されており、本体部２と蓋体部３の接する部分で、本体部２又は蓋体部３の一方の側に小さい突起５３を設け、他方の側に該突起が嵌合可能の小さい凹部５４を形成し、蓋体部３を被せたときには、突起５３が凹部５４に嵌合して、突起の弾性より大きい力が加わらない限り、蓋体部３が本体部２から離脱しないように、また、これとは逆に、突起５３の弾性より大きい力を加えることにより蓋体部３を本体部２から外すことができるように、弾性嵌合用突起５３及び弾性嵌合用の凹部５４の組合せからなる係合部５５が設けられている。
【００２９】
本例において、ガラス基板搬送用ボックスの本体部及び蓋体部は、例えば、ポリエチレン及びポリスチレンのグラフト重合体、ポリエチレン−ポリスチレン系共重合体、ポリプロピレン又はポリエチレンにより製造されている。ポリエチレン−ポリスチレン系共重合体、例えば、ポリエチレン−ポリスチレン系グラフト重合体は、比較的変形し難いために、成形体の形状が安定しており、ガラス基板搬送用ボックスの本体部及び蓋体部用の素材としては好ましい。しかし、搬送時等で起こる衝撃はガラス基板に直接伝わり、ガラス基板の破損を招き易いので、本例においては、これらの衝撃を緩衝材を配置して緩和することによりガラス基板の破損を防止している。本例においては、本体部２の底壁部２６及び蓋体部３の天井壁部２１に、それらと一体に形成されている二条一組の凸条部１４間に、ガラス基板押さえ部１５の挿着用の窪んだ空間１６を形成して、そこに緩衝材としてガラス基板押え部材１５が配置されている。
【００３０】
本例において、ガラス基板押え部材１５は、永久歪の小さい発泡プラスチック製、例えば、発泡ポリエチレン系樹脂で製造されている。本例において、ガラス基板押え部材１５は、ガラス基板に接する面が、平坦又は略平坦又は平滑に形成されており、例えば発泡ポリエチレン系樹脂製の成形体であってもよいが、発泡ポリエチレン系樹脂の板状物から打抜き又は切断により製造されたものを使用することができる。本例において、ガラス基板の下端部は、その両側部が、凸部１２間に形成されているガラス基板挿着用の溝部１３内に保持され、ガラス基板１０の重量は、ガラス基板押え部材１５により支えられている。
【００３１】
本例においては、ガラス基板押え部材１５の厚さは、凸条部１４間のガラス基板装着用の窪んだ空間１６内に該ガラス基板押え部材１５を装着して、底が上がって浅くなった前記ガラス基板装着用の窪んだ空間１６の深さが、ガラス基板１０が、ガラス基板押え部材１５の弾力により、ガラス基板挿着用の溝部１３から簡単に離脱しないような深さとなるように設定される。したがって、ガラス基板押え部材１５の厚さは、ガラス基板装着用の窪んだ空間１６の深さ、即ち凸条部１４の凸部１２の高さより小さく形成され、例えば前記ガラス基板挿着用の窪んだ空間１６の深さの２／３を超えない厚さに形成される。本例において、ガラス基板押え部材１４としては、もとより波形の複数の凹凸を有する従来のパッドの凹凸形状とすることができる。
【００３２】
本例においては、ガラス基板押え部材は、本体部よりも、衝撃が緩和できるように、永久歪の小さいプラスチック発泡体を使用するのが好ましく、例えば、ビーズ成形発泡によるポリエチレン発泡体、ビーズ成形発泡によるポリプロピレン発泡体等のポリオレフィン発泡体、又はビーズ成形発泡によるポリエチレンとポリスチレンの共重合体の発泡体等により形成することができる。また、ガラス基板押え部材は、本体部と同一の発泡体などの単一体よりなる成形体、又はこれらの二種以上の発泡体で形成される積層体とすることができる。
【００３３】
本例において、本体端部部材２２及び２３と、本体中間側部部材２４及び２５とが継合する継合部には、それらの継合が確実であるように、継合部締結部材５６を取付けることができる。継合部締結部材５６による締結は、外側５７及び内側５８の継合部において行われる。この継合部締結部材５６による締結箇所は、本体部２の外側５７及び内側５８において、本体第一及び第二端部部材２２及び２３の端部側壁部２８及び２９と本体中間側部部材２４及び２５並びに中間底部部材２６の中間底部側壁部３９及び４０との継合部とすることができる。この場合、内側の継合部締結部材５６の締結位置が、外側の継合部締結部材５６の締結位置に重なる位置、即ち、丁度その裏側の位置にすると、外側及び内側に位置する夫々の継合部締結部材５６の間に継合部が位置することとなり、外側及び内側の継合部締結部材を一つのピン５９等を挿通して固定することができるので、継合部が外側及び内側の継合部締結部材５６により挟着されて固定される。本例においては、各部材の継合部における継合が確実なものとなり、継合部の継合を補強でき、しかもピン５９の装着本数を少なくでき、且つ仕上がりも綺麗になり好ましい。
【００３４】
そこで、本例においては、外側継合部３１−３７及び３２−４５並びに内側継合部３４−３８及び３５−４６には、夫々、横方向に隣接して縦長の凹部即ち溝６０を形成し、該二つの凹部又は溝６０の間において、継合部で継合される双方の部材の端部に突出部６１及び６２を形成し、突出部６１及び６２は、継合時に溝６０の間で互いに接して並んだ状態となり、断面コの字形の継合部締結部材５６により上から一緒に挟まれた恰好で固定される。本例においては、この装着用の突出部６１及び６２は、その接触端部に半分ずつピン孔が形成されており、継合端部を接触したところで一個のピン孔６３が形成される。本例において、この装着用の突出部６１及び６２と継合部締結部材５６は、締結された状態で継合時に端部に形成される一個のピン孔６３に固定用ピン５９が挿通されて一緒に固定される。本例において、装着用の突出部６１及び６２には、ピン孔６３は、端面を合せて一個形成するようにされているが、突出部の夫々に挿通用のピン孔６３を形成さすることもできる。
【００３５】
本例において、継合部締結部材５６は、例えば断面コの字形等の、並んだ二つの突出部６１及び６２を一緒に抱え込む又は挟み込むような断面形状に形成するのが好ましい。この継合部締結部材５６による締結は、本体第一及び第二端部部材２２及び２３に設けられている突出部６１と、本体中間側部部材２４及び２５並びに中間底部部材２６に設けられている対応する突出部６２とを、縦長の凹部又は溝６０の間で互いに接して並べて、外側５７及び内側５８から継合部締結部材５６により挟んで固定する。外側継合部の突出部６１を、内側継合部の突出部６１と互いに重なり合う位置に設け、外側継合部の突出部６２を、内側継合部の突出部６２と互いに重なり合う位置に設けると、突出部６１及び６２を縦長の凹部又は溝６０内で互いに継合して並んだときに、本体部の外側及び内側の夫々の突出部６１及び６２は、夫々その外側及び内側で重なり合って継合するので、外側及び内側の継合部が、纏め易くなり好ましい。
【００３６】
このように外側及び内側で夫々継合した二組の突出部６１及び６２の上に、夫々断面コの字形の継合部締結部材５６を配置して、継合する二組の突出部６１及び６２を継合部締結部材５６のコの字形の中に押し込むことにより、該コの字形の継合部締結部材５６をもつて、前記継合する二組の突出部６１及び６２を上から抱えるように挟着することができる。この挟着後、継合部締結部材５６のピン孔６６及び突出部６１及び６２のピン孔６３に、固定ピン５９を挿通して、外側及び内側の二つの継合部締結部材５６を、前記突出部６１及び６２を間に位置させて互いに固定する。このように固定された継合部締結部材５６間に挟着された突出部６１及び６２は、外側及び内側の継合部締結部材５６間で固定されて、継合部締結部材５６間から外れなくなるので、本体第一及び第二端部部材２２及び２３と、本体中間側部部材２４及び２５並びに本体中間底部部材２６とは、継合により、容易に離れることがなくなり、確りと安定して固定させることができる。これにより、本体第一及び第二端部部材２２及び２３と、本体中間側部部材２４及び２５並びに本体中間底部部材２６とを確実に締結させることができる。
【００３７】
本例において、継合部端に形成される、継合部締結部材５６の装着用の突出部６１及び６２は、何れも一方の端面が、これに継合する他方の端面に合致するように形成されるのが好ましい。このように継合部端部に突出部６１及び６２が、端面において、互いに合致する形状に形成されていると、本体第一及び第二端部部材２２及び２３と、本体中間側部部材２４及び２５並びに本体中間底部部材２６とが継合するときに、本体第一及び第二端部部材２２及び２３の突出部６１と、本体中間側部部材２４及び２５並びに本体中間底部部材２６の突出部６２は、夫々の端面で互いに密に接触して、断面コの字形の継合部締結部材５６のコの字形部内に抱えられた時に、互いに凭れあって破損等が起こり難くなり、緩むことなく接触した形状を維持して継合を安定させることができる。
【００３８】
本例においては、継合部の溝内に形成される突出部６１及び６２が、継合時に接触して、断面コの字形の継合部締結部材５６のコの字形部内に抱え持たれる形状に形成され、この場合、突出部６１及び６２の間に形成されるピン挿通孔６３及び継合部締結部材のピン挿通孔６６に固定ピンを挿通させることにより継合部締結部材５６による締結を確実にさせるのが好ましい。本例において、継合部締結部材５６は、板状や棒状等とすることができるが、断面コの字形に形成されると、縦長の凹部又は溝間に形成された突出部６１及び６２を凹部又は溝側双方から把持し易くなるので好ましい。本例においては、凹部又は溝間で締結するので、継合部締結部材５６を被せて継合部を締結しても、継合部締結部材の上面が溝の上面から上に出ないようにすることができる。
【００３９】
本例においては、ガラス基板搬送用ボックスの密閉性を保つために、蓋体部３は印籠蓋に形成されており、本体部２の上端部は、印籠蓋の蓋体部３の下端部の内側形状に合わせて、外側に段部、即ち断面切欠き状の切欠き部６４が形成されている。本例において、各本体部材の継合部、即ち外側継合部の３１−３７及び３２−４５、内側継合部の３４−３８及び３５−４６並びに底部継合部３３−４８及び３６−５０は、ホゾ継手の接合構造に形成されている。しかし、ホゾに限らず、一方が突起部又は凸条部を形成し、他方に突起部が嵌合可能の穴又は突条部が嵌合可能の溝に形成することができる。
【００４０】
本例は以上のように構成されているので、各継合部にける継合は、各継合部を継合して、突出部同士を付合わせて隣接させ、その隣接した突出部の上に継合部締結部材を被せて固定ピンを挿通して、夫々の突出部を互いに固定することにより行われる。
本例においては、組立装置を用いて組立てることが出来る。この場合、組立装置は、例えば、両側で加圧可能に案内部材により圧縮可能に形成されている、一対の組み立て用の型枠を備え、内側に、型枠の圧縮時に成形部材を内側から支え保護する支持型枠を備える組立て装置（図示されていない）を使用することができる。例えば、第一端部部材２２を装置の一方の型枠内に装着し、本体中間側部部材２４及び２５と本体中間底部材を、継合部４１−４３及び４２−４４を継合して本体中間部材組立体を一体に組立て、この組立てられた本体中間部材組立体と本体第一端部部材２２を、継合部３１−３７、３２−４５及び３３−４８を継合する。次いで、本体中間部材組立体と本体第二端部部材２３を、継合部３４−３８、３５−４６及び３６−５０を継合する。継合作業により組立てられた本体部仮組立て体は、支持型枠で内側から支えながら、組立て装置により、双方の端部側から加圧されて、確りと組立てられる。この組立て方は、ホゾの形状及びホゾ穴（溝形状を含む）の形状により種々の態様をとることができる。端部側壁部継合部３３及び３４に、ホゾ穴６５を上端から下方に形成すると、本体中間側部部材２４及び２５の取付けは、本体組立の最終組立段階で行うことができる。
【００４１】
確りと組立てられた本体部２の組立て体は、凡ての隣接する突出部に、継合部締結部材５６が嵌着されて、固定ピン５９が挿通されて固定されて、組立てられた本体部として、組立て装置から取出される。この場合、外側継合部３１−３７及び３２−４５並びに内側継合部３４−３８及び３５−４６において、並んだ二つの突出部６１及び６２の上に、断面コの字形の継合部締結部材５６を被せて、突出部６１及び６２のピン穴６３と継合部締結部材５６のピン穴６６とを合わせて、固定ピン５９を突出部６１及び６２のピン穴６３及び継合部締結部材５６のピン穴６６を挿通する。そして、外側５７及び内側５８の突出部６１及び６２の上に継合部締結部材５６を固定し、本体中間側部部材２４及び２５の側壁部継合部３７及び３８を、対応する本体第一及び第二端部部材２２及び２３の側壁部継合部３１及び３４に継合させ、本体中間側部部材２４及び２５を本体第一及び第二端部部材２２及び２３に継合させることができる。本例においては、固定ピンは、突出部６１及び６２の双方の端面に半分宛形成されている挿通孔６３を挿通されており、突出部６１及び６２間の固定ピン５９の数は一個とされているが、突出部６１及び６２に、ピン穴６３を夫々一個宛形成することもできる。
【００４２】
図６乃至図８に示す実施例は、図５に示す実施例と、継合部締結部材５６の点で相違している。即ち、図６及び図７に示す実施例においては、継合部締結部材５６が横に長く形成されているのに対し、図５に示す実施例においては、継合部締結部材５６は、本体部２の高さ方向に略全長に亘る長さで縦に長く形成されている点で相違している。本例においても、本体部組立て体は、組立て装置により端部側から加圧されて、確りと組立てられる。
本例においては、本体部２の外側５７において、本体第一端部部材２７の側壁部２８及び２９には、横方向に延びる凹部又は溝部６０が形成されており、凹部又は溝部６０に接して継合部３１には突出部６１が形成されている。また本例においては、本体中間側部部材２４においては、溝部６０は、小さく形成されている。本例において、本体中間側部部材２４の溝部６０に接して継合部３７には突出部６２が形成されている。本例において、本体第一端部部材２７の側壁部２８及び２９の継合部３１の突出部６１の端面並びに本体中間側部部材２４の突出部６２の端面には固定ピン５９を挿通するためのピン挿通孔６３が、夫々半分宛形成されており、前記突出部６１及び６２を合わせることにより、一つのピン挿通孔６３が形成される。
【００４３】
本例において、本体中間側部部材２４の継合部３７には、夫々前記ホゾ等の継合凸部６７が形成されており、本体第一及び第二端部部材２７の側壁部２８の継合部３１には、夫々、前記継合凸部６７が嵌入可能のホゾ穴等の継合凹部６５が形成されている。本例において、固定ピン５９はワンタッチピンであり、雄型ピン６８と雌型ピン６９とで構成されている（図９参照）。本例における本体中間側部部材２５の継合部３８にはホゾ等の継合突部６７が設けられており、本体第一及び第二端部部材２７の側壁部２９の継合部３４には、前記ホゾ等の継合突部６７が嵌入可能のホゾ穴等の継合凹部６５が形成されている。本体第一端部部材２７の継合部３１と本体中間側部部材２４の継合部３７の継合は、本体中間側部部材２４の継合部３７の継合凸部６７を第一端部部材２７の継合部３１の継合凹部６５内に嵌合して行われる。
【００４４】
本例において、本体第一端部部材２７の継合部３１と本体中間側部部材２４の継合部３８とが継合されたところで、継合部締結部材５６の両端部を突出部６１及び６２の脇の凹部又は溝６０内に押し込み固定して、本体第一端部部材２７の継合部３１と本体中間側部部材２４の継合部３８とが継合され締結される。この継合部締結部材５６による締結は、固定ピン５９を、外側及び内側の突出部６１及び６２に取付けられている外側及び内側の継合締結部材５６を通して固定することにより行われる。この固定ピン５９による継合締結部材５６の取付けは、本体部２の外側５７から、雌型ピン６９を、外側継合部締結部材５６のピン挿通孔６６及び突出部６１及び６２の挿通孔６３を挿通して装着し、装着された雌型ピン６９に、内側から雄型ピン６８を内側継合部締結部材５９のピン挿通孔６６及び突出部６１及び６２の挿通孔６３を挿通して、既に装着されている雌型ピン６９内に押込んで装着される。このようにして、雄型ピン６８及び雌型ピン６９で構成される固定ピン５９を突出部６１及び６２並びに継合部締結部材５６に取付けて、継合締結部５６を突出部６１及び６２の上に固定する。継合部締結部材５６を取付けない箇所においては、溝部及び突出部も形成されていないので、組となる一方の継合部の継合凸部を組となる他方の継合部の継合凹部に嵌合させて固定する。

このような継合操作を各継合部で行って、本体第一及び第二端部部材２７に、その間に配置される本体中間側部部材２４及び２５並びに本体中間底部部材２６を取付けることができる。本例においても、本体第一及び第二端部部材２７の外側継合部３１及び内側継合部３４と中間側部部材２４及び２５の外側の継合部３７及び内側の継合部３８との継合、並びに本体第一及び第二端部部材２７の外側継合部３２及び３３並びに内側継合部４６及び５０との継合は、継合部３１−３７の継合、継合部３２−４５の継合、継合部３３−４８の継合、継合部３４−３８の継合及び継合部３５−４６の継合及び継合部３６−５０の継合である。また、中間側部部材２４及び２５の継合部４１及び４２と中間底部部材２６の継合部４３及び４４との継合は、継合部４１−４３の継合及び継合部４２−４４の継合である。これらの継合は、何れも一方の継合部に継合凸部６７を形成し、他方の継合部に継合凹部６５を成して、継合凸部６７を継合凹部６５内に嵌入して固定される。本例において、継合１４−２０、１５−２８、１６−３１、１７−２１、１８−２９、１９−３２、２４−２６及び２５−２７の中、継合１４−２０、１５−２８、１７−２１及び１８−２９は、継合部締結部材４４を取付けて継合されているが、その他の継合１６−３１、１９−３２、２４−２６及び２５−２７には継合部締結部材５６は取付けられておらず、したがって溝部６０並びに突出部６１及び６２も設けられていない。このようにすることにより継合部締結部材を取付ける継合作業を少なくでき、締結に要する手間を省くことができる
【００４６】
本例において、組立てられた本体部２を分解するときは、先ず、各継合部に取付けられている固定ピンを、夫々の継合部締結部材５６及び突出部６１及び６２から取り外して、本体第一及び第二端部部材２７の側壁部２８及び２９の各端部側壁部継合部３１及び３４と、本体中間側部部材２４及び２５の中間側部継合部３７及び３８との継合を外す。また、本体第一及び第二端部部材２７の側壁部２８及び２９の各端部側壁部継合部３２、３３，３４及び３５と、本体中間底部部材２６の中間底部側壁部３９及び４０の中間底部側壁部継合部４５、４６、４８及び５０との継合を外す。これらの継合の取り外しは、各継合部における継合凸部６７を継合凹部６５から引出して、本体第一及び第二端部部材２７の側壁部２８及び２９と本体中間側部部材２４及び２５を分離し、本体第一及び第二端部部材２７の側壁部２８及び２９と、本体中間底部部材２６を分離し、本体中間側部部材２４及び２５を本体中間底部部材２６と分離する。このようにして、組立てられた本体部２を分解する。本例において、使用された固定ピンであるワンタッチピンは、分解時に破壊されるので、組立てるときは、新たにワンタッチピン等の固定ピンを使用して組立てることになる。取外し可能なピンを使用するときは、組立時に再度使用することが可能である。
【００４７】
図９に示す実施例は、本体部のみに係る実施例であるが、ガラス基板搬送用ボックスの本体部であり、図６及び図７に示す実施例と同様に、蓋体部を被せることにより、ガラス基板搬送用ボックスが形成される。本例は、図６及び図７に示す実施例と比較して、（１）継合部の溝部内に形成される突起部に、夫々一個宛固定ピンを挿通する挿通孔が形成されている点、及び（２）これに対応して継合部締結部材には、固定ピン挿通孔が２個並んで形成されている点で、図６に示す実施例と相違し、その他の点は図６及び図７に示す実施例と同様である。即ち、本例においても、本体部２は、図６及び図７に示す実施例における本体第一及び第二端部部材２７並びに本体中間側部部材２４及び２５並びに本体中間底部部材２６を継合して形成される。
【００４８】
以上の例において、底部付きの本体部２は、発泡倍率４〜２５倍のポリエチレンとポリスチレンの共重合体の発泡体である。発泡倍率が４倍未満では軽量化、ガラス基板保護性（クッション性）の付与、断熱性付与などの目的を充分に達成しえず、一方発泡倍率が２５倍を超えるときは強度が不足し、弾力性が過多となるので好ましくない。
【００４９】
本例において、ポリエチレンとポリスチレンの共重合体の発泡体は、好適には、発泡剤を含むポリエチレンとポリスチレンの共重合体のビーズ又はその一次発泡体を金型内充鎮し、所定の温度に加熱することにより製造される。発泡剤としては揮発性発泡剤、化学分解型発泡剤などが用いられ、２種以上の発泡剤を組み合わせて用いることもできる。ビーズ発泡法は低圧発泡であるので、金型としてはアルミニウム型のような低コストの金型を用いることがきる。このようなビーズ発泡法に代え、他の方式の発泡法を採用することもできる。
【００５０】
本例において、ガラス基板搬送用ボックス１は、本体部２及び蓋体部３は、ポリエチレンとポリスチレンの共重合体の発泡体製とすることができる。この場合、樹脂発泡体製の本体部の継合部の厚さは、強度を考慮して、３乃至１２０ｍｍ、好ましくは３０乃至１００ｍｍとすることができる。蓋体部については、クリロニトリル・ブタジエン・スチレン樹脂（ＡＢＳ）製とすることができる。
【００５１】
本体部の内外両面の表面は、壁内部よりも緻密なスキン構造に形成される。たとえば発泡成形に際し、後加熱を行なえば、金型内面に接触している表面のみを緻密なスキン構造に形成することができる。この場合のスキン構造の表面から１ｍｍ深さまでの部分の密度は、内部の密度よりも１．５倍以上、好ましくは２倍以上大きくするのが好ましい。表面のみを緻密なスキン構造にすることは、発塵性の防止、強度の向上、耐水性・耐透湿性の向上の点で有利である。
【００５２】
本例において、ガラス基板押え部材１５としては、本体部と同様に、発泡体を使用するのが好ましく、例えば、ビーズ成形発泡によるポリエチレン発泡体又はビーズ成形発泡によるポリプロピレン発泡体等のポリオレフィン発泡体、或いはビーズ成形発泡によるポリエチレン・ポリスチレン共重合樹脂発泡体或いは本体部と同一の発泡体などの単体よりなる成形体、又はこれらの二種以上で形成される積層体とすることができる。
ＴＦＴ（薄膜トランジスタ）形成済みのガラス基板や液晶セルの完成パネルを収容するときは、ボックスの少なくとも本体部２には、体積固有抵抗値が１０^３〜１０^１２Ω・ｃｍの樹脂発泡体とすることが望ましい。これにより必要な帯電防止性が得られる。
【００５３】
本例は、以上のように構成されているので、蓋体部３の側壁部は、本体部の開放部を覆って、本体部２の内側凸壁部に接して配置される。本例において、ガラス基板は、その両端部を本体部２のガラス基板保持部４の溝部内に装着し、次いで蓋体部３を本体部２に固定することにより、搬送可能に収容することができる。ガラス基板をガラス基板搬送用ボックス１内に収容して搬送する場合には、蓋体部３が本体部２から離脱することが無いように、ボックス１にバンド掛け又はテープ掛けができるように、蓋体部３の天板部５の上面には、テープ掛け用の溝部が形成されている。このようにガラス基板搬送用ボックス全体をテープ掛けすることにより、本体部から蓋体部が離脱することが無くなり、ボックス１内のガラス基板は本体部２と蓋体部３により確りと保持されることとなり、ガラス基板の搬送時における安全性を確保することができる。このようにバンド又はテープ掛けされたボックス１は、さらにポリオレフィンフィルムやアルミニウムラミネートフィルムなどの防湿性を有する包装材により包装することができる。ガラス基板の取り出しは、本体部２から蓋体部３を外して、手動により、またはロボットにより行なうことができる。
【００５４】
以上の例に示したガラス基板搬送用ボックスは、ボックスの本体部２をポリエチレンとポリスチレンの共重合体の単一発泡成形体で形成している。この本体部２を構成するポリエチレンとポリスチレンの共重合体の単一発泡成形体は、見かけ比重（ＪＩＳ−Ｋ−６７６７）は、例えば、０．０２５ｇ／ｃｍ^３でボックス自身の重量が軽く、また、２５％圧縮強さ（ＪＩＳ−Ｋ−６７６７）が、例えば、１．２ｋｇｆ／ｃｍ^２であり、引張り強さ（ＪＩＳ−Ｋ−６７６７）が、例えば、３．４ｋｇｆ／ｃｍ^２であり、曲げ強さ（ＪＩＳ−Ａ−９５１１）が、例えば、３．０ｋｇｆ／ｃｍ^２であり、落球衝撃値（５０％破壊高さ）（ＪＩＳ−Ｋ−７２１１）２９ｃｍであって、移動・積み重ね・搬送に際し取り扱い易い上、そのすぐれたクッション性のため、落下、振動などが加わったときであってもボックス内に収容されているガラス基板の損傷が有効に防止され、ボックス自身の損傷も有効に防止される。
ポリエチレンとポリスチレンの共重合体の単一発泡成形体で本体部を形成する場合には、発泡倍率で１０乃至２５倍であるのが好ましく、さらに発泡倍率が１５乃至２０倍であるのが好ましい。ポリエチレンとポリスチレンの共重合体の単一発泡成形体は、強度が大きく、引き裂きや摩擦に対しても大きな抵抗性を有し、発塵もなく、水洗等の洗浄も可能である。
【００５５】
本体部２を構成するポリエチレンとポリスチレンの共重合体の単一発泡成形体が、見かけ比重（ＪＩＳ−Ｋ−６７６７）が、０．０５０ｇ／ｃｍ^３である場合には、２５％圧縮強さ（ＪＩＳ−Ｋ−６７６７）は、例えば、２．７ｋｇｆ／ｃｍ^２であり、引張り強さ（ＪＩＳ−Ｋ−６７６７）が、例えば、７．５ｋｇｆ／ｃｍ^２であり、曲げ強さ（ＪＩＳ−Ａ−９５１１）が、例えば、５．５ｋｇｆ／ｃｍ^２であり、落球衝撃値（５０％破壊高さ）（ＪＩＳ−Ｋ−７２１１）６４ｃｍであり、機械的強度を一段と増加させることができる。
【００５６】
ボックスの本体部を樹脂発泡体で構成したことは、ボックス１個当りの樹脂使用量が極めて少なくて済むので、樹脂消費量の点からも製造コストが小さくなる。加えて、樹脂発泡体の成形は、低圧発泡法により行なうことができるので、アルミニウム金型などの安価な金型を用いることができ、金型コストの点で有利である。
【００５７】
【発明の効果】

However, the glass substrate has a smooth surface, and there is also a problem of minute foreign matter such as dirt, scratches, bubbles, and dust on the surface. In order to avoid this, it is made of a foamed plastic which is precisely formed and has good dimensional stability. However, since foamed plastic with good dimensional stability is relatively hard, holding the glass substrate only with foamed plastic with good dimensional stability may cause the glass substrate to be damaged by a slight impact during transportation.

BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the main body of the glass substrate transport box (hereinafter, referred to as the main body) has a foaming ratio of 3 in order to provide a cushioning property for protecting the glass substrate housed in the main body and a heat insulating property. It can be produced from a polyolefin foam having a foaming ratio of from 30 to 30, preferably from 4 to 25. Examples of the polyolefin-based foam include a polyethylene foam, a polypropylene foam, a polystyrene foam, a polyethylene-polystyrene copolymer foam, and a foam of a polymer blend thereof. In the present invention, in particular, as the polyolefin foam, for example, polyethylene / polystyrene copolymer resin foam by bead molding foaming, polyethylene foam by bead molding foaming, polystyrene foam by bead molding foaming, and polypropylene foam by bead molding foaming Can be used.
[0007]
In the present invention, the lid portion (hereinafter, referred to as the lid portion) of the glass substrate transport box can be a foamed plastic molded body, similarly to the main body portion. In this case, it is preferable that the main body and the lid are formed of the same material. However, the lid body can be a transparent or opaque resin molding. In the present invention, the color tone of the main body portion and the color tone of the lid portion are made different to clarify the boundary between the main body portion and the lid portion, and the lid portion is the main body portion, and the main body portion is the lid portion. Part can be prevented from being mistaken.
[0008]
In the present invention, the main body can be formed continuously or integrally with the side wall and the bottom wall. In this case, the bottom wall portion of the main body portion has a side wall portion erected continuously from the peripheral end portion, and an inner surface of the bottom wall portion has a corresponding glass of the opposite end side wall portion of the main body portion. Protrusions are formed to protrude inward in directions intersecting with the direction of connecting the end holding grooves of the substrate. In the present invention, the lid can be formed continuously and integrally with the side wall and the ceiling wall. In this case, the ceiling wall portion of the lid portion hangs down the side wall portion continuously from the peripheral edge portion, and the inner surface of the ceiling wall portion has a corresponding glass of the opposite end side wall portion of the main body portion. Protrusions are formed to protrude inward in directions intersecting with the direction of connecting the end holding grooves of the substrate. On each surface of the ridge portion, a groove for holding a glass substrate is formed in a direction connecting a corresponding groove for holding a glass substrate of a side wall portion facing the main body portion, and the groove is formed of glass. A substrate end is formed so as to be held in the groove. In order to be able to hold the glass substrate pressing member, a depressed space for inserting and attaching the glass substrate pressing member is formed between each pair of the ridges. The depressed space for inserting and holding the glass substrate pressing member is, when the glass substrate pressing member is mounted in the space and the glass substrate is held in the glass substrate transport box, by the glass substrate pressing member, Enables elastic retention of the edge of the glass substrate.
[0009]
In the present invention, in order to facilitate attachment of the glass substrate pressing member to the main body, when the main body is formed of two main members with a bottom, the mounting of the glass substrate pressing member is facilitated. At least a part of the side wall of the one bottomed main body member can be formed low. In this case, the side wall portion is attached to the lower side wall portion, and the height can be adjusted to the side wall portion of the other main body member with the bottom. In this case, by changing the length of one of the main body members with the bottom, the main body can be formed to a desired length. When the main body is divided into three main body members having a bottom and formed in an assembling form, the main body members with the bottom portions at both ends are formed to have the same length, and the length of the main body member with the middle bottom portion is equal to the length of the main body member. By changing only the length, a main body having a desired length can be formed. Also, by changing the length of the main body member with the bottom at one end, a main body having a desired length can be formed. Thus, even when the main body is divided into three main body members with a bottom and formed in an assembled form, the side wall of one main body member among the three main body members with a bottom, for example, with an intermediate bottom The side wall of the main body member can be formed low so that the glass substrate pressing member can be easily attached. In this case, the side wall portion is attached to the lower side wall portion so that the height of the side wall portion can be adjusted to the height of the side wall portion of the other bottomed main body member.
[0010]
Thus, when the main body is formed in an assembled form of two or more, that is, a plurality of bottomed main body members, each bottomed main body member for the main body to be molded can be reduced in size, and a large molded body can be formed.

[0047]
The embodiment shown in FIG. 9 is an embodiment related to only the main body, but is a main body of the box for transporting a glass substrate. As in the embodiments shown in FIGS. 6 and 7, the cover shown in FIG. Then, a glass substrate transport box is formed. This embodiment is different from the embodiment shown in FIGS. 6 and 7 in that (1) a projection hole formed in the groove of the joint portion is provided with an insertion hole for inserting a fixing pin for each one. (2) Correspondingly, the connecting portion fastening member is different from the embodiment shown in FIG. 6 in that two fixing pin insertion holes are formed side by side. 6 and the embodiment shown in FIG. That is, also in this example, the main body 2 joins the main body first and second end members 27, the main body middle side members 24 and 25, and the main body middle bottom member 26 in the embodiment shown in FIGS. Formed.
[0048]
In the above example, the bottomed main body 2 is a polyethylene-polystyrene copolymer foam having an expansion ratio of 4 to 25 times. When the expansion ratio is less than 4 times, the objectives of weight reduction, imparting glass substrate protection (cushioning properties) and heat insulation cannot be sufficiently achieved, while when the expansion ratio exceeds 25 times, the strength is insufficient, It is not preferable because the elasticity becomes excessive.
[0049]
In the present example, the foam of the copolymer of polyethylene and polystyrene is preferably filled in a mold with beads of the copolymer of polyethylene and polystyrene containing a foaming agent or a primary foam thereof, and heated to a predetermined temperature. It is manufactured by heating. As the foaming agent, a volatile foaming agent, a chemically decomposable foaming agent, and the like are used, and two or more foaming agents can be used in combination. Since the bead foaming method is low-pressure foaming, a low-cost mold such as an aluminum mold can be used as a mold. Instead of such a bead foaming method, another type of foaming method can be adopted.
[0050]
In the present embodiment, the main body 2 and the lid 3 of the glass substrate transport box 1 can be made of a foam of a copolymer of polyethylene and polystyrene. In this case, the thickness of the joint portion of the main body made of the resin foam may be 3 to 120 mm, preferably 30 to 100 mm in consideration of strength. The lid can be made of acrylonitrile-butadiene-styrene resin (ABS).
[0051]
The surfaces of the inner and outer surfaces of the main body are formed into a denser skin structure than the inside of the wall. For example, if post-heating is performed during foam molding, only the surface in contact with the inner surface of the mold can be formed into a dense skin structure. In this case, the density of the portion from the surface of the skin structure to a depth of 1 mm is preferably 1.5 times or more, and more preferably 2 times or more, the internal density. Having a dense skin structure only on the surface is advantageous in terms of preventing dust generation, improving strength, and improving water resistance and moisture permeability.
[0052]
In this example, as the glass substrate holding member 15, it is preferable to use a foam as in the case of the main body, for example, a polyolefin foam such as a polyethylene foam formed by bead molding or a polypropylene foam formed by bead molding, Alternatively, it may be a molded article made of a single body such as a polyethylene / polystyrene copolymer resin foam formed by bead molding and foaming or the same foam as the main body, or a laminate formed of two or more of these.
When accommodating a glass substrate on which a TFT (thin film transistor) is formed or a completed panel of a liquid crystal cell, at least the main body 2 of the box has a volume resistivity of 10%. ³ -10 ¹² It is desirable to use a resin foam of Ω · cm. This provides the required antistatic properties.
[0053]
In this example, the configuration is as described above, so that the side wall of the lid 3 covers the opening of the main body and is disposed in contact with the inner convex wall of the main body 2. In this example, the glass substrate can be transportably housed by mounting both ends of the glass substrate in the groove of the glass substrate holding portion 4 of the main body 2 and then fixing the lid 3 to the main body 2. it can. When the glass substrate is accommodated in the glass substrate transport box 1 and transported, the box 1 can be banded or taped so that the lid 3 does not separate from the main body 2. A groove for tape hanging is formed on the top surface of the top plate 5 of the lid 3. In this manner, the entire glass substrate transporting box is taped, so that the lid is not detached from the main body, and the glass substrate in the box 1 is securely held by the main body 2 and the lid 3. As a result, safety at the time of transporting the glass substrate can be ensured. The box 1 thus banded or taped can be further packaged with a moisture-proof packaging material such as a polyolefin film or an aluminum laminated film. The glass substrate can be taken out by removing the lid 3 from the main body 2 and manually or by a robot.
[0054]
In the box for transporting a glass substrate shown in the above example, the main body 2 of the box is formed of a single foam molded article of a copolymer of polyethylene and polystyrene. The single-foam molded article of the copolymer of polyethylene and polystyrene constituting the main body 2 has an apparent specific gravity (JIS-K-6767) of, for example, 0.025 g / cm. ³ The weight of the box itself is light, and the 25% compressive strength (JIS-K-6767) is, for example, 1.2 kgf / cm. ² And the tensile strength (JIS-K-6767) is, for example, 3.4 kgf / cm ² And the bending strength (JIS-A-9511) is, for example, 3.0 kgf / cm. ² It has a falling ball impact value (50% breaking height) (JIS-K-7211) of 29 cm. It is easy to handle when moving, stacking and transporting, and because of its excellent cushioning property, it has been dropped and vibrated. Even at this time, damage to the glass substrate contained in the box is effectively prevented, and damage to the box itself is also effectively prevented.
When the main body is formed of a single foam molded article of a copolymer of polyethylene and polystyrene, the expansion ratio is preferably 10 to 25 times, and more preferably the expansion ratio is 15 to 20 times. A single foam molded article of a copolymer of polyethylene and polystyrene has high strength, has high resistance to tearing and friction, does not generate dust, and can be washed with water or the like.
[0055]
A single foam molded article of a copolymer of polyethylene and polystyrene constituting the main body 2 has an apparent specific gravity (JIS-K-6767) of 0.050 g / cm. ³ , The 25% compressive strength (JIS-K-6767) is, for example, 2.7 kgf / cm ² And the tensile strength (JIS-K-6767) is, for example, 7.5 kgf / cm. ² And the bending strength (JIS-A-9511) is, for example, 5.5 kgf / cm. ² And the falling ball impact value (50% breaking height) (JIS-K-7211) is 64 cm, and the mechanical strength can be further increased.
[0056]
Since the body of the box is made of a resin foam, the amount of resin used per box is extremely small, so that the manufacturing cost is reduced in terms of resin consumption. In addition, since the resin foam can be formed by a low-pressure foaming method, an inexpensive mold such as an aluminum mold can be used, which is advantageous in terms of mold cost.
