【発明が解決しようとする課題】
しかしながら、前述した特開平１０−１１４３８２号公報のガラス管包装体では、輸送時に衝撃が加わると、結束されたガラス管にキズが生じ、または破損するおそれがあるという問題がある。また、輸送時の振動により、ガラス管の内面に塗布された蛍光膜が剥げ落ちるおそれがあるという問題がある。
【０００６】
また、前述した特開平０９−２９５６８６号公報のガラス管包装体では、前述したキズ、破損および蛍光膜の剥げ落ちを防止するために、複数の凹部を上下両面側に具備したスペーサを設ける必要があるので、ガラス管包装体の構成が複雑になり、コストも高くなるという問題がある。
【０００７】

【００４２】
以下、図面を参照して本発明の実施の形態を説明する。
【００４３】
図１は実施の形態に係るガラス管包装体１００の外観を示す斜視図であり、図２は図１に示すＡ方向から見たガラス管包装体１００の部分断面図であり、図３は図１に示すＢ方向から見た蛍光灯１４を包装したガラス管包装体１００の断面図であり、図４は図１に示すＢ方向から見た蛍光灯１４を包装する前のガラス管包装体１００の断面図であり、図５は蛍光灯１４の構成を示す正面図であり、図６は実施の形態に係るガラス管包装体１００を構成するダンボール部材７の展開図である。
【００４４】
ガラス管包装体１００は、長方体形状をしており、５段×５列に山谷状に積み上げられた２５本の蛍光灯１４を互いに密着させて包装し、この２５本の蛍光灯１４を締め付けるように包むためのダンボール部材７によって構成されている。ダンボール部材７は、日本工業規格（ＪＩＳＰ３９０２、ＪＩＳＰ３９０４）によって規定されるＡＢフルートによって構成されている。
【００４５】
ＡＢフルートは、段山数３４±２／３０センチメートル（ＪＩＳ）で厚み約５ミリメートルのＡフルートと段山数５４±２／３０センチメートル（ＪＩＳ）で厚み約３ミリメートルのＢフルートとが互いに積層されて構成されている。従って、ＡＢフルートの厚みは約８ミリメートルである。ＡＢフルートは、高い湿度においてもダンボール強度が高いという特性を有しているため、ダンボール部材７をＡＢフルートによって構成すると、形状安定性が良好になる。
【００４６】
蛍光灯１４は略円筒形状をしており、蛍光灯１４の両端には、円板形状をした金属製の端部１５が設けられている。各端部１５には、円柱形状をした２本の端子１６が、蛍光灯１４の長手方向に沿って突出するようにそれぞれ設けられている。蛍光灯１４の一方の端子１６の先端から他方の端子１６の先端までの全長Ｌは、例えば１２１３．６ミリメートル（ＪＩＳ４０ｗタイプ）である。
【００４７】
蛍光灯１４を載せるために長方形状に形成された底板部６をダンボール部材７は有している。蛍光灯１４の長手方向に沿って蛍光灯１４を両側から囲むように底板部６の両端から底板部６に垂直な方向に沿って底板部６と一体にそれぞれ形成された略長方形状の側板部４および側板部５とがダンボール部材７には設けられている。側板部４および側板部５は、５段×５列に積み上げられた２５本の蛍光灯１４に押し付けられるようにそれぞれ形成されている。
【００４８】
側板部５から底板部６に平行な方向に沿って蛍光灯１４を覆うように側板部５と一体に形成された天板１をダンボール部材７は有している。天板１には、略半円形状をした６個の凹部が互いに所定の間隔を空けて形成されている。天板１の両端に形成された凹部とその凹部に隣接する凹部との間には、側板部４の内面１３に向かって押し付けられるように形成された２つの端面２がそれぞれ設けられている。
【００４９】
端面２から側板５の内面２６までの幅Ｗ１は、例えば約１５２．５ミリメートルであり、底面６の内面の幅Ｗ２よりもＷ３＝約１０ミリメートル狭くなっている。全長Ｌの蛍光灯１４の両端から距離Ｌ２＝０．２１１３Ｌの位置であるエヤリ点（Ａｉｒｙｐｏｉｎｔ）および／またはその近傍に相当する２つの位置に端面２は形成されている。ここでエヤリ点とは、梁が凸状にも凹状にも撓まないように梁を支持することができる梁の長手方向に沿った２箇所の位置をいう。２つのエヤリ点および／またはその近傍において保持された蛍光灯は、凸状に撓むこともなく、凹状に撓むこともなく、長手方向に沿って一直線の形状に維持される。
【００５０】
ダンボール部材７には、側板部４から底板部６に平行な方向に沿って天板１を覆うように略長方形状の天板３が側板部４と一体に形成されている。
【００５１】
天板１の天板３によって覆われる側の表面には、天板１と天板３とを接着するためのダンボール用接着剤が塗布された略円形状の接着領域２７、２８および２９が、互いに所定の間隔を空けて長手方向に沿って配置されている。両側の接着領域２７および２９は、全長Ｌの蛍光灯１４のエヤリ点および／またはその近傍に相当する２つの位置にそれぞれ配置されている。ダンボール用接着剤は、例えば−３０℃〜６０℃において接着に使用されるホットメルトによって構成されており、ホットメルトスプレーガンによって接着領域２７、２８および２９にそれぞれ塗布される。
【００５２】
ダンボール用接着剤によって接着された天板１と天板３との間には、点状に塗布された各ダンボール用接着剤の間において人間の指を挿し込むことができる程度の隙間が形成されている。このため、蛍光灯１４を包装したダンボール部材７を開梱するために、天板１と天板３との間の隙間に指を差し込むことによって、ダンボール用接着剤によって天板１に接着された天板３を天板１から容易に引き離すことができる。
【００５３】
このように、天板１に形成された端面２が側板部４の内面１３に押し付けられるように、側板部５と側板部４とによって蛍光灯１４を押圧するので、ダンボール部材７の弾性力に基づいて５段×５列の蛍光灯１４が締め付けられる。
【００５４】
ダンボール部材７は、蛍光灯１４の端部１５に設けられた端子１６を保持するための端子保持部材８を有している。端子保持部材８は、底板部６に垂直な方向に沿って端子１６と対向するように折り曲げられ、底板部６と一体に形成された端側面９と、側板部５に垂直な方向に沿って端子１６と対向するように側板部５と一体に形成された端側面１１と、側板部４に垂直な方向に沿って端子１６と対向するように側板部４と一体に形成された端側面１０と、天板３に垂直な方向に沿って端子１６と対向するように天板３と一体に形成された端側面１２を含んでいる。
【００５５】
端側面９、端側面１１、端側面１０および端側面１２は、互いに重なり合うように折り曲げられている。端側面９、端側面１１、端側面１０および端側面１２を互いに重なり合うように折り曲げるために、底板部６と側板部４との間、底板部６と側板部５との間および側板部４と天板３との間には、所定の段差がそれぞれ形成されている。
【００５６】
端側面９、端側面１１、端側面１０および端側面１２は、互いに重なり合うように設けられており、ＡＢフルートの厚みは、前述したように約８ミリメートルである。従って、端側面９、端側面１１、端側面１０および端側面１２の総厚みは、約３２ミリメートルである。端側面９、端側面１１、端側面１０および端側面１２によって保持される蛍光灯１４の端子１６の長さは、約６．６０ミリメートル〜約７．６２ミリメートルである。従って、蛍光灯１４の端子１６は、端側面９、端側面１１、端側面１０および端側面１２を突き抜けることはない。
【００５７】
また、ＡＢフルートの端側面９、端側面１１、端側面１０および端側面１２が互いに４層に重なり合うように設けられているので、耐湿性を高めることができる。
【００５８】
図７はガラス管包装体１００によって蛍光灯１４を包装するための包装組立て装置１５０の外観を示す斜視図であり、図８〜図１０は包装組立て装置の構成および動作を説明するための断面図である。
【００５９】
包装組立て装置１５０は、ベース２１を備えている。ベース２１は、ガラス管包装体１００を構成するダンボール部材７の底板部６をその上に保持する。ベース２１には、ダンボール部材７の側板部５を保持するための側板部保持部材２２と、ベース２１上に設けられた支点４３の周りに回動自在に設けられ、ダンボール部材７を挟んで側板部保持部材２２と対向するように設けられた押し出し屈曲器２３とが配置されている。支点４３には、アーム４６が回動自在に取り付けられている。アーム４６には、樹脂製の側板部２４がダンボール部材７の側板部４を押圧するために設けられている。
【００６０】
アーム４６の先端には、支点４４が設けられている。支点４４には、アーム４７が支点４４の周りに回動自在に取り付けられている。アーム４７には、樹脂製の側板部２５がダンボール部材７の天板３を折り曲げるために設けられている。アーム４７の先端には、支点４５が設けられている。支点４５には、アーム４７を側板部保持部材２２にロックするためのロック部材３１が支点４５の周りに回動自在に取り付けられている。
【００６１】
このように構成された包装組立て装置１５０によってガラス管包装体１００に複数の蛍光灯１４を包装するガラス管包装方法を説明する。図１１は実施の形態に係るガラス管包装方法の手順を示すフローチャートである。
【００６２】
まず、図８に示すように、ベース２１に底板部６が保持されており、上方向に向かって開口するように側板部５が側板部保持部材２２によって保持され、側板部４が側板部押え２４によって保持されるように、側板部保持部材２２と押出屈曲器２３との間にダンボール部材７を置く（ステップＳ１）。
【００６３】
そして、ダンボール部材７の一方の端側面９を蛍光灯１４の端子１５と対向するように折り曲げる。次に、端側面９を覆うように端側面１０を折り曲げ、端側面１０を覆うように端側面１１を折り曲げて端側面１１を覆うように端側面１２を折り曲げる（ステップＳ２）。
【００６４】
そして、上方向に向かって開口するダンボール部材７に、側板部５と底板部６と側板部４とによって包まれるように２５本のガラス管を５段×５列に詰め込む（ステップＳ３）。
【００６５】
その後、折り曲げられた一方の端側面９、端側面１０、端側面１１および端側面１２に向かって５段×５列の蛍光灯１４を押し込む（ステップＳ４）。次に、図９に示すように、実質的に水平な方向に沿って側板部４側に天板１を折り曲げる（ステップＳ５）。その後、天板１の接着領域２７、２８および２９にダンボール用接着剤をスプレーガンによって塗布する。
【００６６】
そして、ダンボール部材７の弾性力に基づいて５段×５列の蛍光灯１４を締め付けるために、ステップＳ５によって折り曲げられた天板１の端面２に向かって側板部４を押し出すようにアーム４６を支点４３の周りに回動させながら、天板１を覆うように天板３を折り曲げるために、アーム４７を支点４４の周りに回動させて天板部押え２５によって天板３を押圧する（ステップ６）。次に、アーム４７を側板部保持部材２２にロックするために、アーム４７に取り付けられたロック部材３１を支点４５の周りに回動させる。その後、天板１の接着領域２７、２８および２９に塗布されたダンボール用接着剤によって天板３が天板１と接着する。
【００６７】
そして、ダンボール部材７の他方の端側面９を蛍光灯１４の端子１５と対向するように折り曲げる。次に、他方の端側面９を覆うように他方の端側面１０を折り曲げ、他方の端側面１０を覆うように他方の端側面１１を折り曲げて他方の端側面１１を覆うように他方の端側面１２を折り曲げる（ステップＳ７）。
【００６８】
その後、アーム４７の側板部保持部材２２へのロックを解除するように、アーム４７に取り付けられたロック部材３１を支点４５の周りに回動させる。そして、天板１に接着された天板３から天板部押え２５が離れるようにアーム４７を支点４４の周りに回動させ、側板部押え２４が側板部４から離れるようにアーム４６を支点４３の回りに回動させる。
【００６９】
