【０００２】
【従来の技術】
従来、電子材料フィルム等を巻き取ったロール等の筒状物を梱包部署から使用部署に搬送する場合、筒状物を紙製の段ボール箱に入れて搬送することが行われていた。
紙製の段ボール箱は一度使用すると損傷や吸湿などで強度が低下するため、使用不能となることが多く、段ボールゴミとなる。また、筒状物を支えるアタッチメントとしての支え板、スペーサーなどや箱の固定に用いられているポリプロピレンバンド、テープ、接着剤もゴミとして廃棄しなければならなかった。そこで、何度も繰り返し再使用が可能であり、環境に負荷を与えず、リユース、リサイクルが可能な素材で構成されかつ搬送が容易な上、筒状物の梱包が容易で安定して梱包できる梱包装通い容器が要求されている。
【０００３】

本発明はまた、分解、油化リサイクル又は熔融マテリアルリサイクルが可能で、焼却しても環境に害を与えないプラスチック単一又は複合素材で構成されていることを特徴とする梱包装容器に関する。
【０００７】
【作用】
本発明の梱包装容器は、部材がすべて一体化して構成されており、ひもやテープなどの包装用の副資材を必要とせず、ワンタッチで組立て及び折り畳みが可能である。また、プラスチック段ボール等のリサイクル可能な環境に害を与えない材料を使用しており、何度も再生でき、資源、資材が節減と繰り返し有効活用ができ、多少のイニシャルコストはかかるがファイナルコストを大幅に低減することができる。また、１回使用毎に紙製段ボール、並びにひもやテープなどの包装用の副資材のゴミが発生せず、使用済に於いても廃棄せず再生、再活用すべくマテリアルリサイクル可能なＰＰ、ＰＥ、ＡＢＳ樹脂等の容器素材及び部品素材で統一することで、回収、再利用が可能である。さらに、このような素材はメルト油化分解により処理可能であるため、燃料、代替ガソリンなどのサーマルリサイクル原料となる。例えば、ハロゲン原子、窒素原子、硫黄原子などの環境に有害な原子を含まない熱可塑性樹脂を用いると、サーマルリサイクルによる燃料への活用においても、焼却時のＳＯ_ｘ、ＮＯ_ｘ、ハロゲン化合物などの有害物を発生せず、環境負荷を低減し、環境対応にも優れている。
また、部材は紙粉などを発塵しない材料であるためクリーンであり、またプラスチック段ボールは空隙構造の板状物であり軽量で保冷、保温性にも優れている。
【０００８】
本発明の電子材料フィルムロールの梱包装方法は、上記の梱包装容器を用いているので、電子材料フィルムロールの挿入が容易で、かつ安定して固定保持できる。また、電子材料フィルムロールの自動挿入にも対応できる。また、電子材料フィルムロールを使用後、簡単に折り畳むことができ、梱包部署に返送する際には、容器の容積を大幅に小さくすることができ、部材が一体構造であるため折り畳みもワンタッチに行うことができ、電子材料フィルムロールの収納をワンタッチで収納できると共に減容も簡単に行うことができる。また、副資材、部材が分割タイプのものと異なり、紛失のおそれや別管理の煩雑さがなく、使い勝手に優れている。
【０００９】
【実施例】
本発明の梱包装容器及び梱包装方法で梱包装する電子材料フィルムロールとしては、例えば、感光性フィルム、表示材液晶下地用フィルム、銀フィルム等をロール状に巻き上げたロールが挙げられる。
図１は本発明の一態様の梱包装容器の箱形の組立状態を示す斜視図であり、図２は図１の梱包装容器の折り畳み状態を示す斜視図である。図３は図１の梱包装容器のＡ−Ａ部分断面図であり、図４はＢ−Ｂ部分断面図である。ポリプロピレン製の矩形の枠体１の相対向する枠体短辺１ａにポリプロピレン製のプラスチック段ボールからなる２枚の側板２がそれぞれ取り付けられており、側板の枠体取り付け部にはプラスチック製段ボールの厚さの一部を切断してなるヒンジ部４が設けられ、側板２は内側に折り曲げ可能な構造となっている。枠体の四隅には、コーナー保持枠１７が取り付けられている。各コーナー保持枠１７は、枠体の四隅の外周部から上方へ突出する突部を有しており、これにより複数の梱包装容器を、ずれや荷崩れを起こさずに段積みすることができる。枠体及びプラスチック段ボールの材質は上記のものに限られないが、溶融再生、再利用が可能であり、廃棄の際にはリサイクルが可能なように、ポリエチレン、ポリプロピレン、ＡＢＳ樹脂等の油化又は分解可能な熱可塑性プラスチックであることが好ましく、ポリエチレン、ポリプロピレンが特に好ましい。
【００１０】
枠体１の枠体長辺１ｂには、プラスチック段ボール製のコの字状の底板部３ａと側板部３ｂ、３ｃとからなる底板付き側板３が取り付けられている。側板部３ｂ、３ｃの各々の枠体取り付け部下部と、側板部３ｂ、３ｃの各々の中央部と側板部３ｂ、３ｃと底板部３ａの各々の連結部にはプラスチック段ボールの厚さの一部を切断してなるヒンジ部４が設けられており、コの字状の底板付き側板３は折り折り畳み可能な構造となっている。枠体１の一辺にはヒンジ部４′を介して蓋５が取り付けられている。ヒンジ部４′内側には、隙間からの塵埃の侵入を防止するための弾性を有するシールシートを取り付けることが好ましい。蓋５の内面側の中央部には発泡ポリスチレン製の電子材料フィルムロールと非接触又は接触状態で保護し得る蓋天部緩衝シート６（蓋天部緩衝体の一例）が張り付けられている。
【００１１】
蓋５の開口辺５ａには、中央部に蓋５のプラスチック段ボールを下方に直角に折り曲げたタブ部１０ａが設けられ、タブ部１０ａ下部には左右にタブ部１０ａの一部を内側に折り曲げたロック爪部１１ａが設けられており、枠体１に係合可能な係止部を構成している。この係止部により簡単に蓋をすることができる。
【００１２】
側板２の各々の内側には電子材料フィルムロールの端部を保持するためのロール支えが側板と一体に設けられている。この実施例においては、電子材料フィルムロールの端部を受容する半円形底部を持つ切り欠き部７を有するロール支え板８が板状の発泡ウレタン製の弾性部材９を介して一体に設けられている。ロール支え板８には電子材料フィルムロールの端部が切り欠き部７に容易に受容されるように、梱包装容器上部側に、電子材料フィルムロールの端部をガイドするガイドテーパー１２が設けられている。電子材料フィルムロールの端部を受容する切り欠き部７の形状は、半円形のほかに、矩形であっても、多角形であっても、放物線形であってもよい。また、ロール支え板と弾性部材により電子材料フィルムロールが保持できれば切り欠き部は必ずしも必要ではない。即ち、ロール内径担持、内筒支えの場合は必要ではない。
弾性部材９は、収納する電子材料フィルムロールの長さが変化した場合においても、電子材料フィルムロールの側面を保持できるようなバネ弾性力を有する伸縮部材であることが好ましい。弾性部材としては、気体を内包するマット、空気袋、発泡ポリエチレン、発泡ポリプロピレン、発泡ウレタン、スポンジ、ゴム弾性体などの材質からなるものが好ましく、必要により金属バネ体を用いてもよい。また、図１に示すように、弾性部材９を側板のヒンジ部より下に設けることが好ましい。このように取り付けることにより、電子材料フィルムロールの収容が容易となり、また、側板のヒンジ部付近が開放され、梱包装容器の折り畳みが容易となる。例えば、弾性部材を側板のヒンジ部より下に設け、更にロール支え板の切り欠き部との間に空間を設けることが好ましい。空間は、弾性部材に切り欠き部を設けて形成してもよいし、図１〜４に示すように、ロール支え板の切り欠き部７を避けるように弾性部材９を分割して貼付けてもよい。
また、本実施例においては、電子材料フィルムロールの外側をロール支え板で保持しているが、電子材料フィルムロールの筒内に挿入された筒あるいは棒により電子材料フィルムロールを保持してもよい。
【００１３】
図３は図１のＡ−Ａ断面図、図４は図１のＢ−Ｂ断面図である。弾性部材９は下方に広がるテーパーを有しており、電子材料フィルムロールをガイドし入れやすく、また弾性を有するため電子材料フィルムロールの長さの変化に対応でき、電子材料フィルムロールの両端を押さえ、安定して収納することができる。また、弾性部材９は、側板２のヒンジ部４より下に設けられているため、梱包装容器の折り畳みが容易であり、また、切り欠き部７と側板２との間に空間を形成するように３つに分割されて設けられているため、電子材料フィルムロール端部をを切り欠き部７に容易に受容することができる。
【００１４】
ロール支え板８の表面には、滑り性を有する高密度ポリプロピレン製等の表層シート８ａが張り付けられており、電子材料フィルムロールの受容性を良好にしている。表層シート８ａの材質としてはその他に高密度ポリエチレン、パーフルオロエチレンなどが用いられる。表層シートは単層のみならず、複層化したものであってもよい。滑り性の他に耐久性、耐引き裂き性に優れたものが好ましい。ロール支え板８は剛性シート８ｂと緩衝軟質シート８ｃを複数枚交互に積層した積層体からなり、緩衝軟質シートが剛性シートより切り欠き部内側上部に突き出した構造をしており、電子材料フィルムロールやそのカバーフィルムの損傷を防止している。剛性シート８ｂとしてはポリプロピレンシートが用いられており、ポリエチレンシート、プラスチック製段ボールであってもよく、緩衝軟質シート８ｃとしては発泡ポリエチレンシートが用いられており、発泡ポリプロピレンシート等も用いられる。
【００１５】
ロール支え板８と弾性部材９の間には、プラスチック段ボール製の突当板１３が設けられており、該突当板１３がロール支え板８の切り欠き部に相当する面部分で半円形の形状に表出した突当面部１３ａと、突当面部１３ａの上辺の中央部から上方に短冊状に伸び、先端が内側に折り曲げられて電子材料フィルムロール押さえ爪１３ｂを形成している。この電子材料フィルムロール押さえ爪１３ｂにより電子材料フィルムロールが安定的に固定される。また、突き当て板１３の短冊の下部の突当面部１３ａには左右に切り込みが入れられており、電子材料フィルムロール押さえ爪１３ｂに弾性を付与し、電子材料フィルムロールの挿入時に電子材料フィルムロール押さえ爪１３ｂを開放ガイドし、電子材料フィルムロールの挿入を容易にするとともに、挿入後はプラスチックのバネ弾性により電子材料フィルムロール押さえ爪１３ｂを平面に戻し、電子材料フィルムロール押さえ爪１３ｂはロック状態となり、電子材料フィルムロールが安定的に固定される。
【００１６】
また、ロール支え板は、本実施例の態様のものに限られるものではなく、種々の態様のものが使用可能であるが、剛性体と軟質緩衝体からなり、軟質緩衝体が剛性体より表出し、表層面を被う構造のものを用い、電子材料フィルムロールの端面を緩衝保護することが好ましい。
【００１７】
底板３ａには中央部に蓋天部緩衝シート６と同じ材質の底部緩衝シート１４が張り付けられており、電子材料フィルムロールを大きな衝撃より保護する。底板部３ａの側縁は上部に折れ曲がってタブ部３ａ′を形成し、タブ部３ａ′には側板２の下端の一部を折り曲げて形成した側板係止用突起１５を梱包装容器を組み立てたときに嵌合して側板２を固定するための嵌合孔１６が設けられている。
【００１８】
図１に示す箱型の組立状態の梱包装容器に電子材料フィルムロールを挿入すると、電子材料フィルムロールは損傷せずに、容易に安定に保持して梱包することができる。電子材料フィルムロールを取り出した後は、図２、図３及び図４に示すように、左右の側板２をヒンジ部４を軸として上に引き上げ、次いで底板付き側板をヒンジ部４で折り畳むことにより、一体化した保持アタッチメントがワンタッチで簡単に扁平な形状に折り畳まれ、容積を大幅に減少することができる。枠体１の各短辺１ａ外側には、中央部に下方に折り曲げられたタブ部１０ｂが設けられ、タブ部１０ｂ下部には左右にタブ部１０ｂの一部を内側に折り曲げたロック爪部１１ｂが設けられている。梱包装容器の折り畳み時には、ロック爪部１１ｂが嵌合孔１６に嵌合し、折り畳み状態を維持する。
【００１９】
【発明の効果】
以上説明したように、本発明の梱包装容器及び梱包装方法は、電子材料フィルムロールを自動又は半自動で容易に、安定に保持して梱包することができる。また、弾性部材を備えることにより電子材料フィルムロールの幅の変化にも追従することができる。更に、本発明の梱包装容器は梱包部署から使用部署まで搬送し、電子材料フィルムロールを取り出した後、ワンタッチで折り畳んで製造部署に返送することを繰り返し行うことが可能なリユース通い箱であり、分離された部材、部品がなく、結束バンド、テープ、接着剤などのゴミの発生がない。また、使用部材として環境負荷の少ない循環可能な部材を使用すれば、廃棄する場合もリサイクル性にも優れている。
