Description

【０００１】
【発明の属する技術分野】
この発明は順次２倍のサイズとなるように形成した一連の容器体について収容物を収容した状態において積み上げ及び空の状態において積み重ね可能に構成した運搬用容器に関するものである。
【０００２】
【従来の技術】
従来、運搬用容器の第１容器体は有底四角箱状に形成され、対向する各一対の長側壁及び短側壁が互いに上部ほど広くなるようにテーパ状をなすとともに、各一対の長側壁の中央で色分けされている。第１容器体の上端にはその外周面を取り囲むように横方向に延びる上部フランジが形成されるとともに、第１容器体の高さ方向の中央には下部フランジが上部フランジと平行に延びるように形成されている。各一対の長側壁及び短側壁の外面において下部フランジから下方には、四角柱状をなす脚部がそれぞれ一対ずつ第１容器体の高さ方向に延びるように突設されている。各側壁の内面において上部フランジ及び下部フランジ間には、脚部と対応する形状の脚部収容凹部が一対ずつ凹設され、これら脚部収容凹部と脚部は平面から見た第１容器体の中心を基準に点対称位置となっている。
【０００３】
そして、収容物が収容された状態にある第１容器体はその短側壁の色が上下の第１容器体の間で揃うように位置合わせすることにより、下方位置の第１容器体上に積み上げ可能に構成されている。また、空の状態の第１容器体はその短側壁の色が上下の第１容器体の間で異なるように位置合わせして、下方位置の第１容器体内にその下半部を収容することにより積み重ね可能に構成され、省スペースで保管することができるようになっている。
【０００４】
運搬用容器の第２容器体は第１容器体に対し、その長側壁の長さを第１容器体の短側壁の２倍の長さとし、その短側壁の長さを第１容器体の長側壁の長さと同じとして形成され、第１容器体と同様の上部及び下部フランジを有している。また、第１容器体と同様に各一対の長側壁の中間で色分けされている。第２容器体の各側壁には第１容器体の脚部及び脚部収容凹部と同形状かつ同様に点対称の位置関係となるように脚部及び脚部収容凹部が各短側壁にそれぞれ一対ずつ、各長側壁にそれぞれ二対ずつ配設されている。そして、複数の第２容器体同士は第１容器体と同様に収容物を収容した状態又は空の状態で積み上げ又は積み重ね可能に構成されている。
【０００５】
上記の第２容器体の短側壁に設けられた脚部及び脚部収容凹部は、第１容器体の長側壁に設けられた脚部及び脚部収容凹部と対応するように配設されている。加えて、第２容器体の長側壁に設けられた脚部及び脚部収容凹部は、第１容器体を短側壁方向に並列した状態で、各短側壁に設けられた脚部及び脚部収容凹部と対応するように配設されている。
【０００６】
これら第１容器体及び第２容器体はそれぞれの短側壁及び長側壁の位置を合わせることにより、収容物を収容した状態で第２容器体上に第１容器体を積み上げたり、空の状態で第２容器体内に第１容器体の下半部を収容し、積み重ねたりすることができるように構成されている。そして、収容物を収容した状態の第１容器体及び第２容器体は積み上げた状態で搬送先へ搬送されるとともに、搬送先で収容物が無くなり、空となった状態で重合され、できるかぎり省スペースとなるように積み重ねられて搬送又は保管されるようになっている。
【０００７】
【発明が解決しようとする課題】
ところが、上記従来の運搬用容器によれば、第１容器体及び第２容器体は共に各一対の長側壁の中間で色分けされている。収容物を収容した状態又は空の状態で上方位置の第１容器体と下方位置の第２容器体の積み上げ又は積み重ねを行う際、それぞれの短側壁及び長側壁が位置合わせされることから、位置合わせされた各側壁の全面が一色に揃うことがない。このため、第１容器体及び第２容器体の収容物を収容した状態又は空の状態における積み上げ又は積み重ねを行う場合には、作業者がその場で各容器体を回転させ、各容器体の向きを確認する必要があり、こういった作業が煩雑であるという問題があった。
【０００８】
この発明は、このような従来技術に存在する問題点に着目してなされたものである。その目的とするところは、サイズの異なる複数の容器体を収容物を収容した状態で積み上げることができ、空の状態で省スペースに積み重ねることができるとともに、この積み上げ及び積み重ね作業を容易に行うことができる運搬用容器を提供することにある。
【０００９】
【課題を解決するための手段】
上記の目的を達成するために、請求項１及び請求項２に記載の運搬用容器の発明は、有底四角箱状をなし、対向する各一対の長側壁及び短側壁が互いに上部ほど広くなるようにテーパ状をなす容器体と、この容器体の上部位置に横方向に延びる上部フランジと、前記各一対の側壁のうち少なくとも一対の側壁外面に突設され、収容物が収容された状態にある容器体を上下に積み上げるとき、下方位置の容器体の上部フランジ上に載置され、上方位置の容器体を支持するための脚部と、この脚部と対応する位置となる側壁の内面に凹設され、空の状態にある容器体を上下に積み重ねるとき、脚部をその内側に収容するための脚部収容凹部とを備え、所定サイズの基準容器体に対し、その長側壁の長さを基準容器体の短側壁の２倍の長さとし、その短側壁の長さを基準容器体の長側壁の長さと同じとする２倍容器体を構成し、前記基準容器体を長側壁の中間で色分けしてその半部を着色部とするとともに、前記２倍容器体を短側壁の中間で色分けしてその半部を前記基準容器体の着色部と同色の着色部とした。
とくに、請求項１に記載の発明では、前記基準容器体及び２倍容器体における前記脚部と脚部収容凹部とを側壁の長さ方向の中央を基準とする線対称位置に設け、基準容器体及び２倍容器体が空の状態でその中に同じサイズの容器体を収容して積み重ねる関係にしたとき、下方の容器体の着色部と上方の容器体の着色部とが同じ側となることにより、下方の容器体と上方の容器体との位置関係を識別可能に構成し、前記２倍容器体の着色部側の長側壁に形成された脚部収容凹部を、前記基準容器体の着色部側の短側壁に形成された脚部に対応する位置に凹設し、２倍容器体が空の状態でその中に基準容器体を収容して積み重ねる関係にしたとき、基準容器体の着色部と２倍容器体の着色部とが同じ側となることにより、前記基準容器体と２倍容器体との位置関係を識別可能に構成した。
とくに、請求項２に記載の発明では、前記基準容器体及び２倍容器体における前記脚部と脚部収容凹部とを容器体の平面内の中心を基準とする点対称位置に設け、基準容器体及び２倍容器体内に収容物を収容した状態で、その上に同じサイズの容器体を積み上げる関係にしたとき、下方の容器体の着色部と上方の容器体の着色部とが同じ側となることにより、下方の容器体と上方の容器体との位置関係を識別可能に構成し、前記２倍容器体の着色部側の長側壁に形成された脚部収容凹部を、前記基準容器体の着色部ではない側の短側壁に形成された脚部に対応する位置に凹設し、２倍容器体内に収容物を収容した状態で、その上に基準容器体を積み上げる関係にしたとき、基準容器体の着色部と２倍容器体の着色部とが同じ側となることにより、前記基準容器体と２倍容器体との位置関係を識別可能に構成した。
【００１２】
【発明の実施の形態】
（第１実施形態）
以下、この発明の第１実施形態を、図面に基づいて詳細に説明する。
【００１３】
図１（ａ），（ｂ）に示すように、運搬用容器の第１容器体１１は上面を開口した有底長四角箱状に形成され、内部に機械部品、食品、薬品等の収容物が収容されるようになっている。第１容器体１１の対向する各一対の長側壁１１ａ及び短側壁１１ｂは互いに上部ほど広くなるテーパ状に形成されている。また、第１容器体１１は各一対の長側壁１１ａの中央で色分けされ、図中において、正面側となる前半部は着色されることにより着色部１４となっている。
【００１４】
第１容器体１１の上端には、上部フランジ１２が第１容器体１１の外周面を取り囲むように横方向に延出形成されるとともに、第１容器体１１の高さ方向における中央よりも上方には、下部フランジ１３が上部フランジ１２と平行に延びるように横方向に延出形成されている。
【００１５】
第１容器体１１の各側壁１１ａ，１１ｂの外面には、それぞれ一対ずつ、合計四対の脚部１５が第１容器体１１の上端から下端にかけて高さ方向に延びるとともに、その両側面が互いに上部ほど広くなるテーパ状に突設されている。さらに、各脚部１５の下端部には段差状をなす係止角部１５ａが切り欠き形成されている。
【００１６】
各一対の脚部１５の位置関係は、それぞれの側壁１１ａ，１１ｂの長さ方向の中央を基準として線対称となるように配設されている。また、一方の短側壁１１ｂ側、つまり着色部１４側に設けられた一対の脚部１５の間隔は、他方の短側壁１１ｂに設けられた一対の脚部１５の間隔よりも短くなるように設定されている。同様に、着色部１４側から見て右側となる一方の長側壁１１ａに設けられた一対の脚部１５の間隔は他方の長側壁１１ａに設けられた一対の脚部１５の間隔よりも短くなっている。
【００１７】
第１容器体１１の各側壁１１ａ，１１ｂにおいて、前記脚部１５と対応する位置の内面には脚部収容凹部１６が設けられている。この脚部収容凹部１６は前記脚部１５と対応する形状となるように、両側面が互いに上部ほど広くなるテーパ状をなしている。そして、脚部１５と脚部収容凹部１６とはそれぞれの側壁１１ａ，１１ｂの長さ方向の中央を基準として線対称となっている。
【００１８】
次に、運搬用容器の第２容器体２１について説明する。なお、これ以降に挙げる容器体については前記第１容器体１１と異なる点を中心に説明する。
図２（ａ），（ｂ）に示すように、第１容器体１１を基準容器体とした場合に２倍のサイズとなる２倍容器体としての第２容器体２１はその長側壁２１ａの長さを第１容器体１１の短側壁１１ｂの２倍とし、その短側壁２１ｂの長さを第１容器体１１の長側壁１１ａと同じとすることで形成されている。すなわち、第２容器体２１はその長側壁２１ａが第１容器体１１の短側壁１１ｂと対応し、短側壁２１ｂが第１容器体１１の長側壁１１ａと対応するようになっている。この第２容器体２１は各一対の短側壁２１ｂの中央で色分けされ、図中において、正面側となる前半部は着色されることにより着色部１４となっている。
【００１９】
第２容器体２１の脚部１５及び脚部収容凹部１６は、第１容器体１１を短側壁１１ｂ方向に２個並列した状態でこれらの脚部１５及び脚部収容凹部１６と対応するように、各長側壁２１ａに二対ずつ、各短側壁２１ｂに一対ずつ、合計六対が配設されている。
【００２０】
図４に示すように、収容物が収容された状態の第１容器体１１及び第２容器体２１は、第１容器体１１の脚部１５が下方位置となる第２容器体２１の上部フランジ１２上に載せられることにより積み上げが行われる。この状態で上方位置の第１容器体１１と下方位置の第２容器体２１は、互いの着色部１４が重なり合わずその短側壁１１ｂと長側壁２１ａが異色となるように配置され、第１容器体１１の脚部１５及び第２容器体２１の脚部収容凹部１６が位置ずれした状態となっている。そして、第２容器体２１上には２個の第１容器体１１がその短側壁１１ｂ方向に並列した状態で積み上げられている。
【００２１】
なお、各容器体１１，２１において、下方位置の上部フランジ１２の上面には、上方位置の脚部１５と対応する位置に脚部係合部１２ａが凹設されている。この脚部係合部１２ａには脚部１５の係止角部１５ａが係合されることにより、上下の容器体１１，２１間における横方向の位置ずれが規制されるようになっている。
【００２２】
図５に示すように、空の状態の第１容器体１１及び第２容器体２１は、上方位置となる第１容器体１１が１８０゜回転され、互いの着色部１４が重なり合い、その短側壁１１ｂと長側壁２１ａが同色となるように配置されている。この状態で第１容器体１１の脚部１５及び第２容器体２１の脚部収容凹部１６は位置合わせされた状態となっており、第１容器体１１の脚部１５は下方位置となる第２容器体２１の脚部収容凹部１６の内側に収容されている。また、第１容器体１１の下部フランジ１３が第２容器体２１の上部フランジ１２に係合されることにより、上方位置の第１容器体１１の挿入が規制される。そして、２個の第１容器体１１はその短側壁１１ｂ方向に並列した状態で、その大半が第２容器体２１の内部に収容され、積み重ねられている。
【００２３】
図３（ａ），（ｂ）に示すように、第１容器体１１に対して４倍（２²倍）のサイズとなる第３容器体３１は、第１容器体１１及び第２容器体２１の関係に従って、その長側壁３１ａを第２容器体２１の短側壁２１ｂの２倍の長さとすることで形成されている。この第３容器体３１は各一対の長側壁３１ａの中央で色分けされ、図中において、正面側となる前半部は着色されることにより着色部１４となっている。第３容器体３１の脚部１５及び脚部収容凹部１６は、第２容器体２１を短側壁２１ｂ方向に２個並列した状態でこれらの脚部１５及び脚部収容凹部１６と対応するように、各長側壁３１ａに二対ずつ、各短側壁３１ｂに二対ずつ、合計八対が配設されている。
【００２４】
図６に示すように、収容物が収容された状態の第２容器体２１及び第３容器体３１は互いの着色部１４が重なり合わず、その長側壁２１ａと短側壁３１ｂが異色となるように配置され、この状態で、脚部１５及び脚部収容凹部１６が位置ずれした状態となる。そして、第２容器体２１の脚部１５を下方位置となる第３容器体３１の上部フランジ１２上に載せ、脚部係合部１２ａに脚部１５の係止角部１５ａを係合することにより、２個の第２容器体２１がその短側壁２１ｂ方向に並列した状態で第３容器体３１上に積み上げられる。なお、この状態で第２容器体２１上に第１容器体１１を積み上げることもできるようになっている。
【００２５】
図７に示すように、空の状態の第２容器体２１及び第３容器体３１は、第２容器体２１を１８０゜回転して、互いの着色部１４が重なり合い、その長側壁２１ａと短側壁３１ｂが同色となるように配置され、この状態で脚部１５及び脚部収容凹部１６が位置合わせされた状態となる。そして、第２容器体２１の脚部１５が第３容器体３１の脚部収容凹部１６の内側に収容されるとともに、両フランジ１２，１３の係合により第２容器体２１の挿入が規制され、２個の第２容器体２１はその短側壁２１ｂ方向に並列した状態で、その大半が第３容器体３１の内部に収容され、積み重ねられている。なお、この状態で第２容器体２１内に第１容器体１１を積み重ねすることもできるようになっている。
【００２６】
上記の第３容器体３１を２倍して第１容器体１１の８倍（２³倍）のサイズとなる第４容器体、あるいは第４容器体を２倍して第１容器体１１の１６倍（２⁴倍）のサイズとなる第５容器体も各容器体１１，２１，３１の関係に従って順次形成される。そして、第４容器体ならば各一対の短側壁の中央で色分けされ、第５容器体ならば各一対の長側壁の中央で色分けされる。また、収容物が収容された状態又は空の状態における積み上げ又は積み重ねも上記の各容器体１１，２１，３１と同様にして行われる。さらに、同じサイズの各容器体１１，２１，３１同士を収容物が収容された状態又は空の状態で積み上げ又は積み重ねすることもできるようになっている。
【００２７】
前記第１実施形態の運搬用容器の作用について以下に記載する。
さて、第１実施形態の運搬用容器の各容器体１１，２１，３１は内部に収容物を収容した状態で運搬が行われる。そして、トラックの荷台等に積載されるとき、複数の容器体１１，２１，３１は上下に積み上げられる。
【００２８】
図４に示すように、この場合、まず、第１容器体１１及び第２容器体２１においては、その短側壁１１ｂと長側壁２１ａが異色となるように各容器体１１，２１を配置する。このとき、第１容器体１１の脚部１５と第２容器体２１の脚部収容凹部１６はその位置がずらされた状態となっており、このまま第２容器体２１の上部フランジ１２上に第１容器体１１の脚部１５を載せる。
【００２９】
一方、図６に示すように、第２容器体２１及び第３容器体３１においては、その長側壁２１ａと短側壁３１ｂが異色となるように各容器体２１，３１を配置する。この状態で、その脚部１５と脚部収容凹部１６の位置がずらされ、このままの状態で第３容器体３１の上部フランジ１２上に第２容器体２１の脚部１５を載せる。
【００３０】
そして、必要に応じて第３容器体３１上の第２容器体２１に対し、第１容器体１１を積み上げながら、同様の作業を複数回繰り返すことによって、収容物を収容した状態にある第１容器体１１、第２容器体２１及び第３容器体３１を上下の一方向に延びるように積み上げる。
【００３１】
収容物が無くなり、内部が空となった各容器体１１，２１，３１はその一部が重なり合った状態で上下に積み重ねられ、運搬されるか、あるいは倉庫等において保管される。
【００３２】
図５に示すように、この場合、まず、第１容器体１１及び第２容器体２１においては、その短側壁１１ｂと長側壁２１ａが同色となるように各容器体１１，２１を配置する。このとき、第１容器体１１の脚部１５と第２容器体２１の脚部収容凹部１６は位置合わせされた状態となっている。次に、第１容器体１１を手で持ち、第２容器体２１の上部開口内にその底部を挿入し、脚部１５をその脚部収容凹部１６の内側に係合させる。このまま、第１容器体１１を第２容器体２１内に押し込んでいくと、やがて第１容器体１１の下部フランジ１３が第２容器体２１の上部フランジ１２に係合され、第２容器体２１内に第１容器体１１が積み重ねられる。
【００３３】
一方、図７に示すように、第２容器体２１及び第３容器体３１においては、その長側壁２１ａと短側壁３１ｂが同色となるように各容器体１１，２１を配置し、その脚部１５と脚部収容凹部１６を位置合わせする。この状態で、第３容器体３１の内部に第２容器体２１を押し込むと、第３容器体３１内に第２容器体２１が積み重ねられる。
【００３４】
そして、必要に応じて、第３容器体３１内に積み重ねられた第２容器体２１内に第１容器体１１を積み重ね、同様の作業を複数回繰り返し、空の状態にある各容器体１１，２１，３１を積み重ねる。
【００３５】
上記の第１容器体１１、第２容器体２１及び第３容器体３１は、大きな容器体の長側壁の長さを小さな容器体の短側壁の２倍とし、その短側壁の長さを小さな容器体の長側壁と同じとするという関係に従って順次２ⁿ倍のサイズとなるように形成される。また、ｎが奇数となる容器体は各一対の短側壁の中央で色分けされ、ｎが０及び偶数となる容器体は各一対の長側壁の中央で色分けされる。このため、ｎが奇数となる容器体ならばその長側壁が、ｎが０及び偶数となる容器体ならばその短側壁が同色又は異色となるように各容器体を配置するだけで、サイズの異なる複数の容器体の積み上げ又は積み重ねが迅速に行われる。
【００３６】
前記の第１実施形態によって発揮される効果について、以下に記載する。
・第１容器体１１、第２容器体２１及び第３容器体３１はサイズの小さな基準容器体に対し、その長側壁の長さを基準容器体の短側壁の２倍の長さとし、その短側壁の長さを基準容器体の長側壁の長さと同じとする大きな２倍容器体を構成するといった一定の関係に従って順次２n倍のサイズとなるように形成されている。これにより、サイズの異なる複数の容器体を収容物を収容した状態で積み上げることができ、空の状態で省スペースに積み重ねることができる。また、ｎが奇数となる容器体は各一対の短側壁の中央で色分けされ、ｎが０及び偶数となる容器体は各一対の長側壁の中央で色分けされている。このため、サイズの異なる複数の容器体を積み上げ又は積み重ねる場合には、各容器体の長側壁と短側壁の色を異色又は同色となるように配置するだけであり、この積み上げ及び積み重ね作業を容易に行うことができる。
【００３７】
・各容器体１１，２１，３１における脚部１５と脚部収容凹部１６はそれぞれの側壁１１ａ，１１ｂ，２１ａ，２１ｂ，３１ａ，３１ｂの長さ方向の中央を基準として線対称位置に設けられている。これに加え、脚部１５及び脚部収容凹部１６各側壁１１ａ，１１ｂ，２１ａ，２１ｂ，３１ａ，３１ｂにおいて、同じ位置の外面及び内面に配設されているため、脚部収容凹部１６を各容器体１１，２１，３１の上端から下端にかけてその深さが深くなるように設けることができる。このため、空の状態の容器体１１，２１，３１を積み重ねる際に下方位置の容器体２１，３１内に上方位置の容器体１１，２１の大半を収容することができるため、より省スペースに積み重ねることができる。
【００３８】
・上部フランジ１２上面に脚部係合部１２ａを設け、脚部１５に係止角部１５ａを設け、容器体１１，２１，３１を積み上げる際、脚部係合部１２ａに係止角部１５ａを係合することにより、上下の容器体１１，２１，３１の間における横方向の位置ずれを抑制することができる。
【００３９】
（第２実施形態）
図８（ａ），（ｂ）に示すように、第２実施形態の運搬用容器における第１容器体１１は、各一対の側壁１１ａ，１１ｂが若干だけ上部に広がるテーパ状をなすように形成されている。また、下部フランジ１３は第１容器体１１の高さ方向の中央に形成されている。
【００４０】
この下部フランジ１３から下方において、各側壁１１ａ，１１ｂ外面には四角柱状をなす脚部１５が一対ずつ突設されている。脚部１５の位置関係は、両短側壁１１ｂ上において、着色部１４側の一対は短側壁１１ｂの中央寄りに、他方側の一対は短側壁１１ｂの側方寄りに配設されている。また、各長側壁１１ａ上において、着色部１４側の脚部１５は長側壁１１ａの側方寄りに、他方側の脚部１５は長側壁１１ａの中央寄りに配設されている。
【００４１】
各側壁１１ａ，１１ｂの内面において上部フランジ１２及び下部フランジ１３の間には、脚部１５と対応する形状の脚部収容凹部１６が一対ずつ凹設されている。これら脚部収容凹部１６は脚部１５に対し、平面から見た第１容器体１１の中心を基準に点対称位置に配設されている。
【００４２】
図９（ａ），（ｂ）に示すように、第１容器体１１に対する第２容器体２１は第１実施形態の第１容器体１１及び第２容器体２１の関係に従って形成されている。なお、図示しない第３容器体以降も、同様の関係に従って順次形成されている。
【００４３】
さて、図１０に示すように、第２実施形態の運搬用容器において、収容物が収容された状態にある第１容器体１１及び第２容器体２１は、まず、互いの着色部１４が重なり合い、その短側壁１１ｂと長側壁２１ａが同色となるように配置される。このとき、第１容器体１１の脚部１５は第２容器体２１の脚部収容凹部１６に対し位置ずれした状態になる。このままの状態で、第２容器体２１の上部フランジ１２上に第１容器体１１の脚部１５を載せる。そして、同様の作業を複数回繰り返すことによって、収容物を収容した状態にある第１容器体１１及び第２容器体２１が上下の一方向に延びるように積み上げられる。
【００４４】
図１１に示すように、収容物が無くなり、内部が空となった第１容器体１１及び第２容器体２１は、互いの着色部１４が重なり合わず、その短側壁１１ｂと長側壁２１ａが異色となるように配置される。このとき、第１容器体１１の脚部１５と第２容器体２１の脚部収容凹部１６が位置合わせされた状態になる。このままの状態で、第２容器体２１の上部開口内に第１容器体１１の底部を挿入すると、脚部１５が脚部収容凹部１６の内側に係合される。この状態から第１容器体１１を第２容器体２１内へさらに押し込むと、下部フランジ１３が上部フランジ１２に係合され、第２容器体２１内に第１容器体１１が積み重ねられる。そして、同様の作業を複数回繰り返すことによって、空の状態にある第１容器体１１及び第２容器体２１を積み重ねる。
【００４５】
従って、第２実施形態の運搬用容器によれば、各一対の側壁１１ａ，１１ｂ，２１ａ，２１ｂが底壁に対しほぼ直立しているため、第１実施形態と比較して収容物の収容量を増加させることができる。さらには上方位置となる容器体１１は下方位置となる容器体２１に対し、その下半分のみが収容されるため、容器体１１，２１同士の重なりが少なく、下方位置の容器体２１内から上方位置の容器体１１を取り出す際の抵抗を低減することができる。
【００４６】
なお、本実施形態は、次のように変更して具体化することも可能である。
・各実施形態の順次２ⁿ倍のサイズとなるように形成された容器体において、ｎが奇数となる容器体を各一対の長側壁の中央で色分けし、ｎが０及び偶数となる容器体を各一対の短側壁の中央で色分けしてもよい。あるいは、ｎが奇数となる容器体を、例えば一方の短側壁全面、各一対の長側壁の側縁部分等といった各一対の長側壁の中間で色分けし、ｎが０及び偶数となる容器体をそれと対応するように各一対の短側壁の中間で色分けしてもよい。
【００４７】
このように構成した場合においても、サイズの異なる複数の容器体を収容物を収容した状態で積み上げることができ、空の状態で省スペースに積み重ねることができるとともに、この積み上げ及び積み重ね作業を簡易かつ容易に行うことができる。
【００４８】
・着色部１４は各容器体１１，２１，３１を中間で色分けして、その向きを示すことができるものであれば、容器体の前半部全体を着色するものに限定されず、例えば上部フランジ１２の上面、下部フランジ１３の上面、各側壁１１ａ，１１ｂ，２１ａ，２１ｂ，３１ａ，３１ｂの外面及び内面の少なくとも一方等だけに設けてもよい。あるいは、各側壁における着色部１４の境界が斜め方向に延びるように色分けしてもよい。
【００４９】
さらには、着色部１４と容器体は異なる色相とすることに限定されず、明度の異なる同色としたり、例えば赤と青緑等といった補色の関係としたり、模様等としてもよい。
【００５０】
このように構成した場合においても、容器体１１，２１，３１の方向を目視により容易に確認することができる。
・各実施形態の運搬用容器において、例えば収容物を収容した状態で並列に配置した第１容器体１１上に第３容器体３１を積み上げたり、並列に配置した第２容器体２１上に第３容器体３１を積み上げたり、並列に配置した第１容器体１１上に第２容器体２１を積み上げたりしてもよい。なお、この場合には、上方位置となる容器体の底壁外面に下方位置となる容器体の上部フランジ１２を遊嵌状態で収容する収容溝を凹設するとよい。
【００５１】
