Description

【０００１】
【発明の属する技術分野】
本発明は、例えばレタスなどの野菜類を収納するのに好適な段ボール製包装箱に関するものである。
【０００２】
【従来の技術】
従来からレタスを収納する段ボール製包装箱としては、例えば図７〜図１１に示すように構成されたものが知られている。
【０００３】
以下、図面に基づき説明すると、従来のレタス収納用の段ボール製包装箱は、１組の短辺側の対向側板１，１と、他の組の長辺側の対向側板２，２と、前記短辺側の対向側板１，１の下端に連設された底板形成用フラップ３，３と、前記長辺側の対向側板２，２の下端に連設された底板形成用フラップ４，４と、前記短辺側の対向側板１，１の上端に連設された上蓋形成用フラップ５，５と、前記長辺側の対向側板２，２の上端に連設された上蓋形成用フラップ６，６とから構成されている。
【０００４】
さらに詳しくは、前記長辺側の対向側板２，２の下端に連設された底板形成用フラップ４，４は短辺の長さ方向の中間部で端面同士が近接した状態でステープル７止めにより閉じた状態が保持され、この底板形成用フラップ４，４の上に前記短辺側の対向側板１，１の下端に連設された底板形成用フラップ３，３が載せられて底板が形成されている。また、上蓋については、前記短辺側の対向側板１，１の上端に連設された上蓋形成用フラップ５，５が先に閉じられて、その上から前記長辺側の対向側板２，２の上端に連設された上蓋形成用フラップ６，６が閉じられ、上蓋形成用フラップ６，６は短辺の長さ方向の中間部で端面同士が近接した状態でステープル８止めにより閉じた状態が保持され上蓋が形成されている。
【０００５】
上記構成における従来のレタス収納用の段ボール製包装箱は、底板および上蓋はともにステープル７および８によって止められるようになっているので、ステープル止めのための工具が必要であるという問題があり、また包装箱の内部に収納されたレタス９がステープル７，８に引っ掛かって傷が付くという問題があり、またステープル７および８が包装箱の底面および天面から突出して包装箱の底面および天面がフラットにならず、積み重ね時の安定性が悪いという問題があった。さらに、開梱のためにステープル止め部を外すとき、ステープルによって指を怪我するという問題もあった。
【０００６】
【発明が解決しようとする課題】
本発明はこのような課題を解決するもので、ステープル止めを不要とし、ステープルによる被収納物の傷付き防止を図り、さらに積み重ね時の安定性を向上させるとともに、開梱作業を安全に行なえるようにすることを目的とするものである。
【０００７】
【課題を解決するための手段】
この課題を解決するために本発明は、１組の短辺側の対向側板１１，１１と、他の組の長辺側の対向側板１２，１２と、前記短辺側の対向側板１１，１１の下端に連設された底板形成用フラップ１３，１３と、前記長辺側の対向側板１２，１２の下端に連設された底板形成用フラップ１４，１４と、前記短辺側の対向側板１１，１１の上端に連設された上蓋形成用フラップ１５，１５と、前記長辺側の対向側板１２，１２の上端に連設された上蓋形成用フラップ１６，１６とから構成され、長辺側の対向側板１２，１２の下端に連設された底板形成用フラップ１４，１４は短辺の長さ方向の中間部で端面同士が近接し、前記短辺側の対向側板１１，１１の下端に連設された底板形成用フラップ１３，１３は底板形成用フラップ１４，１４の裏面に当接し、底板形成用フラップ１３，１３の角部を底板形成用フラップ１４，１４に形成された切り込み孔１４ａ，１４ａに差し込むことによって底板が形成され、また前記長辺側の対向側板１２，１２の上端に連設された上蓋形成用フラップ１６，１６は短辺の長さ方向の中間部で端面同士が近接し、前記短辺側の対向側板１１，１１の上端に連設された上蓋形成用フラップ１５，１５は中央の差し込み片１８を除く他の部分１９が上蓋形成用フラップ１６，１６の内面に重なるように上蓋形成用フラップ１６，１６で形成される上蓋の端部に位置し、前記差し込み片１８の先端の板部１８ａを上蓋形成用フラップ１６，１６の突き合わせ部に形成された連続する溝部１６ａに差し込むことにより上蓋が形成されるように構成し、前記差し込み片１８の両側間の幅が前記溝部１６ａの幅よりも僅かに大きくなるように差し込み片１８の両側を出っ張らしてなることを要旨とするものである。
【０００８】
この構成により、底板形成用フラップ１３，１３の角部を底板形成用フラップ１４，１４に形成された切り込み孔１４ａ，１４ａに差し込むことによって底板が形成され、また上蓋形成用フラップ１５，１５の前記他の部分１９の上から上蓋形成用フラップ１６，１６を重ねるとともに、差し込み片１８の先端の板部１８ａを上蓋形成用フラップ１６，１６の溝部１６ａに差し込むことにより上蓋が形成されていて、底板および上蓋ともにステープルが存在せず、従って包装箱の内部に収納されたレタスなどの被収納物がステープルに引っ掛かって傷が付くという怖れがなくなる。また、ステープル止め部を外す必要がないため、開梱時に指を怪我するという問題もなく、開梱作業を安全に行なえる。さらに、包装箱の底面および天面から突出するステープルが存在しないため、包装箱の底面および天面がフラットな状態に近づき、積み重ね時の安定性を向上させることができる。
【０００９】
【発明の実施の形態】
以下、本発明の一実施の形態について、図面に基づいて説明する。
図１〜図６において、本実施の形態のレタス収納用の段ボール製包装箱は、１組の短辺側の対向側板１１，１１と、他の組の長辺側の対向側板１２，１２と、前記短辺側の対向側板１１，１１の下端に連設された底板形成用フラップ１３，１３と、前記長辺側の対向側板１２，１２の下端に連設された底板形成用フラップ１４，１４と、前記短辺側の対向側板１１，１１の上端に連設された上蓋形成用フラップ１５，１５と、前記長辺側の対向側板１２，１２の上端に連設された上蓋形成用フラップ１６，１６とから構成されている点では前記従来例と同じである。
