Description

【０００１】
【産業上の利用分野】
本発明は、分離型空気調和機などの被梱包物を支持し梱包に使用する梱包装置に関するものである。
【０００２】
【従来の技術】
従来の梱包装置は、特開平０５−２２９５４９号公報、特開平１０−２３６４７７号公報などに開示されているように、例えば図６に示すようにトレイ状の底板２１の内側に緩衝材２２、２３を設け、底板２１内の角部に緩衝材２２、２３を合わせることで緩衝材２２、２３を固定する。
【０００３】
更に、この緩衝材２２、２３にて、被梱包物２４を支持し被梱包物２４の上部を持する緩衝材２５、２６を設け最後に外箱２７を被せて被梱包物を梱包させるものであった。
【０００４】
【発明が解決しようとする課題】
しかし、この種の梱包装置は保管時の荷重を外箱で支持するため外箱２７に保管荷重を支持するだけの強度を持たせる必要があり、外箱２７に高価な材質を使用し強度を向上させたり、別部品による補強を加えるなど外箱２７や梱包材料が複雑で高価になるなどの欠点を有していた。
【０００５】
また、被梱包物２４を輸送時の衝撃より保護するため緩衝材２２、２３、２５、２６の肉厚設定など緩衝仕様の決定が難しく、特に衝撃が集中する緩衝材２２、２３、２５、２６の角部の肉厚は厚くする必要があり緩衝材２２、２３、２５、２６自体が大きくなると共に、梱包装置全体も大きくなり梱包装置を構成する材料も高価になり、材料の使用量も増加し梱包材廃棄時の廃棄量にも影響し環境面での負荷も増加する。
【０００６】
更に、緩衝材２２、２３、２５、２６には被梱包物２４の角部以外の側面など面部分での保護機能も同時に形成するため、角部分の保護機能と面部分の保護機能を同時に満足させる肉厚を設定する必要が有り緩衝材２２、２３、２５、２６作成時の工数が多く掛かる。
【０００７】
また、梱包装置を長期保管した場合に外箱２７が保管荷重により変形することがあっても被梱包物２４に荷重が加わらないように、緩衝材２２、２３、２５、２６の形状を改良し外箱２７の歪量を少なくするなど緩衝材２２、２３、２５、２６の作成に多くの知識や工数が必要になり加工が複雑で工数も多くなる。
【０００８】
また、緩衝材２２、２３、２５、２６が底板２１内で容易に位置合わせができるように底板２１をトレイ状に形成したり接着などの固定を追加する必要があり、底板２１の加工工数が増加し材料費も高価になる。
【０００９】
また、梱包作業時の底板２１などの組み立て作業時において、底板２１などに設けた折線で折り曲げる作業が多く、容易に折り曲げ易い折線を設けないと梱包材加工時の作業性が低下する。
【００１０】
そこで本発明は、かかる従来の欠点を全て解消するもので、底板の側面立ち上がり部で保管荷重の支持機能を設け梱包装置の強度向上を図ると共に、底板の両端を二重にして被梱包物の保護機能や加工時の作業性を向上させる梱包装置を提供するものである。
【００１１】
【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、２本の平行の折線を設け、両端を折り曲げ立ち上がり部とすることでコの字状を形成した底板を設け、この底板の内側に被梱包物、及び前記被梱包物を支持する緩衝材を挿入し、更に前記底板全体を覆う外箱を被せる梱包装置において、前記底板両端の立ち上がり部の寸法を前記外箱の高さ寸法と同等以上としたものである。この構成により、安価で最少の部品点数により加工時の作業性にも優れた梱包装置を提供することができる。
【００１２】
【発明の実施の形態】
上記の課題を解決するため請求項１の発明は、２本の平行の折線を設け、両端を折り曲げ立ち上がり部とすることでコの字状を形成した底板を設け、この底板の内側に被梱包物、及び前記被梱包物を支持する緩衝材を挿入し、更に前記底板全体を覆う外箱を被せる梱包装置において、前記底板両端の立ち上がり部の寸法を前記外箱の高さ寸法と同等以上としたものである。
【００１３】
そして、この梱包装置により外箱の耐圧強度を底板で補うことが可能となり梱包装置全体の保管荷重に対する強度が向上し外箱への高価な材料の使用を廃止できるなど安価な梱包装置となる。
【００１４】
請求項２記載の発明は、上記底板において、緩衝材の底面側および側面側に接する底板の部分に、シートを重ねて二重構造としたもので、少ない材料で被梱包物を輸送時の衝撃より保護する保護機能が向上する。
【００１５】
請求項３記載の発明は、緩衝材の底面と外側面とに接する稜線両端の角部、またはその角部を延長した稜線部に三角状のカット部を設けたもので、より少ない材料で被梱包物を輸送時の衝撃より保護する保護機能が向上する。
【００１６】
請求項４記載の発明は、底板をコの字状に形成する底板両端の立ち上がり部の長さより、底板の二重に重ねたシートの側面立ち上がり部分の長さを短くしたもので、外箱の歪量を低減させ耐圧強度を向上させる。
【００１７】
請求項５記載の発明は、シートに形成した凹状の切り込みに、緩衝材の底面部分形成された凸部が嵌入するもので、緩衝材の固定が容易に行えると共に固定のための部品を削減できる。
【００１８】
請求項６記載の発明は、底板と共にコの字状に折り曲げるシートの折線を、前記底板の折線１箇所に対して２本設け、この２本の折線が前記底板の折線を挟み込むように設けたもので、梱包作業時の底板の折り曲げが正確に可能となり組み立て作業性が向上する。
【００１９】
（実施の形態１）
以下本発明の実施の形態について、図１〜図５と共に説明する。
【００２０】
図１において、１は段ボールなどのシートに２本の平行な折線２、３を設けることによりコの字状に形成される底板で、コの字状にした立ち上がり部の寸法ｈ１と外箱４の内寸高さ寸法ｈ２を同等、または底板の寸法ｈ１の方が高くなるように設定する。この底板１には、図２に詳細に示すように底板１をコの字状にする折線２、３の両端側に別部品のシート５、６を重ね合わせることにより二重に構成される。
【００２１】
そして、シート５、６には底板と同様にコの字状に折り曲げる折線７ａ、７ｂ、８ａ、８ｂが設けられており、この折線７ａ、７ｂ、８ａ、８ｂは底板１の折線２、３の折り曲げ１箇所当り２本の平行した折線となっていると共に、図３に示すようにシート５、６を底板１と重ねたときに底板１の折線２、３をシート５、６の折線７ａ、７ｂ、８ａ、８ｂが挟み込むように位置決めし重ね合わせている。
【００２２】
また、図４に示すようにシート５、６の底板の底面部分を形成する面には凹状の切り込み部９、１０が１箇所、または複数箇所設けられている。また、シート５、６は底板１と共にコの字状に折り曲げたときの立ち上がり部寸法が、底板1の立ち上がり部寸法より短くなるような隙間ｔ１、ｔ２を設けている。なお、今回の説明ではシート５、６を別部品として説明したが、底板１の両端を延長し折り返すことでも同様の効果を全て得ることが可能である。
【００２３】
更に、１１、１２は、底板１内に挿入し被梱包物１３を支持する緩衝材で一体型、または上下二分割された形状で被梱包物１３を支持すると共に底板１内に挿入される。この緩衝材１１、１２の底面には、図５に示すように底板１に重ねたシート５、６を逃げるための段差部１４、１５を設け、緩衝材の１１、１２の側面にも同様の段差部を設ける。
【００２４】
そして、緩衝材１１、１２の底面側段差部１４、１５の面上には凸部１６、１７を設ける。この凸部１６、１７は、緩衝材１１、１２を底板１に挿入したとき、シート５、６に設けた切り込み部９、１０と嵌め合わされ、少なくとも外周部の一辺以上が切り込み部９、１０と接する形状で形成されている。
【００２５】
また、緩衝材１１、１２の梱包時の外側になる面と底面に接する稜線の両端角部に三角状のカット部１８、１９を設ける。このカット部１８、１９は、稜線に沿って延長することも可能で、延長したカット部１８、１９が連結し稜線全体のカット部になる場合もある。
【００２６】
このように構成された各部品を使用して、梱包時にはシート５、６を重ね合わせ接着などで固定した底板１をシート５、６と共にコの字状に折り曲げる。このとき、底板１に設けた折線２、３の内側でシート５、６に設けた折線７ａ、７ｂ、８ａ、８ｂが、２本の折線により折り線間で潰れながらシート５、６が底板１と共に容易に折り曲がる。そして、緩衝材１１、１２を底板内に挿入する。
【００２７】
このとき、緩衝材１１、１２の底面に設けた凸部１６、１７がシート５、６の切り込み部９、１０と嵌め合わせることで底板１内での緩衝材１１、１２の位置決めと固定が行われる。更に、被梱包物１３を挿入し最後に外箱４をコの字状となった底板１全体を覆うように被せ結束して梱包が完了する。
【００２８】
上記構成により、コの字状にした底板１の両端の立ち上がり部の高さ寸法を外箱４の高さ寸法と同等、または同等以上としたことにより底板の立ち上がり部と外箱で保管時の荷重を支持することが可能となり梱包装置の耐圧強度が向上すると共に外箱に使用する箱の材質を低減させ安価な梱包装置が可能となる。
【００２９】
また、底板１にシート５、６を重ねたことにより、底板１両端の剛性を増し底板１の強度を上げることで梱包装置が輸送時の外力より衝撃を受けたときの被梱包物１３に加わる衝撃を緩和し、緩衝材１１、１２で保護する緩衝機能を補うことで緩衝材１１、１２自身を薄肉化し、梱包装置自体も小型化が可能となり梱包装置に使用する材料が安価になる。
【００３０】
また、緩衝材１１、１２の底面側と外側面とに接する稜線の角部に三角状のカット部１８、１９を設けることにより、特に角部の緩衝機能について細かな修正が可能で緩衝材１１、１２全体の寸法を変えることなく緩衝機能を微調整させることが可能となり詳細な緩衝材仕様の決定が容易に可能で、最小の材料で安価な緩衝材を作成することができる。
【００３１】
また、底板１の立ち上がり部より底板に重ねたシート５、６の立ち上がり部の長さを短くすることにより、底板１の立ち上がり部先端が外箱４の天面に食い込み易くし、外箱４を構成する段ボール等の板紙の板厚を圧縮し外箱の歪を低減して外箱の保管時の荷重による変形を防止する。
【００３２】
また、底板１に重ねたシート５、６に凹状の切り込み９、１０を設け、緩衝材１１、１２の底面に凸部１６、１７を設けることにより、緩衝材１１、１２を底板１に挿入したときの位置決めと固定が容易に可能となり梱包作業時の作業性が向上する。
【００３３】
また、底板１に重ねたシート５、６に設けた折線７ａ、７ｂ、８ａ、８ｂが底板１の折線２、３を挟み込むように位置決めすることにより、底箱１を折線２、３で折り曲げたときシート５、６が折線７ａ、７ｂ、８ａ、８ｂの２本の折線間で潰れながら容易に折り曲がると共に、底板１の折線２、３を正確に折り曲げることが可能となる。
【００３４】
【発明の効果】
上記実施例でも明らかなように、請求項１記載の発明によれば底板をコの字状にすることにより、底板両端の立ち上がり部で保管時の荷重を外箱と共に支持する構造となり、梱包装置全体の耐圧強度を向上させることができ、保管品質も向上し、外箱に使用する材質も低減させる安価な梱包装置となる。
【００３５】
また、底板両端に重ねるシートを設けたことにより、底板の剛性を増し、強度を上げることで梱包装置が輸送時の外力より衝撃を受けたときの被梱包物を保護する緩衝機能が向上し緩衝材自身を薄肉化し軽量化が図れる。
【００３６】
更に、梱包装置自体も小型化が可能となり梱包装置に使用する材料が安価になると共に、梱包材の材料使用量も削減でき、廃棄時のゴミの量も削減できるなど環境へも配慮も可能となる。
【００３７】
また、緩衝材の底面側と外側面とに接する稜線の角部に三角状のカット部を設けることにより、特に角部の緩衝機能について細かな修正が可能で緩衝材全体の寸法を変えることなく緩衝機能を微調整させることが可能となり、詳細な緩衝材仕様を決めることが容易に可能で、最小の材料で安価な緩衝材を作成することができる。
【００３８】
また、底板の立ち上がり部より底板に重ねたシートの立ち上がり部の長さを短くし、底板の立ち上がり部先端を外箱に食い込ませることにより、外箱の歪を低減させ外箱の保管時の荷重による変形を防止し、保管時の品質を向上させると共に外箱の美観を損なうことも防止できる。
【００３９】
また、底板両端に重ねたシートに凹状の切り込みを設け、緩衝材の底面に設けた凸部を嵌め合わせることで底板への緩衝材の位置決めと固定が容易に行え、緩衝材固を固定するための接着剤も廃止することが可能となり梱包作業時の作業性が向上する。
【００４０】
また、底板に重ねたシートに設けた折線が底板の折線を挟み込むように位置決めすることで、底箱をコの字状に折り曲げるときの作業性が向上すると共に底板が折線で正確に折り曲げることが可能となる。
