Description

【0001】
【発明の属する技術分野】
本発明はクッション性に優れた封筒に関するものである。
【0002】
【従来の技術】
従来から紙製シートからなる封筒本体の内面に、合成樹脂製シートを材料としてエアをセル状に密閉して形成されたバブルシートが袋状に装備され、この袋状のバブルシートで内容物が包まれるようにしてクッション性を持たせた封筒が一般に知られている。
【0003】
前記封筒本体の内面に装着されるバブルシートは封筒本体の内面に対して封筒本体の一端を除く周囲3辺での3方シール部で挟まれて熱溶着により止められ、また封筒本体の一端の内容物の出入口近傍において封筒本体の内面に熱溶着により止められている。つまり、封筒本体の内側2面に重なる2枚のバブルシートは前記封筒本体の一端を除く周囲3辺での3方シール部で同時に封筒本体の内面に対して熱溶着により止められるとともに、2枚のバブルシートの残りの1つの辺は封筒本体の一端の内容物の出入口近傍において封筒本体の内面に熱溶着により止められており、封筒本体の内側2面に重なる2枚のバブルシートの全周は封筒本体の内面に対して熱溶着により完全に接合されていることになる。
【0004】
このような構成のバブルシート付きの封筒を使用後において廃棄処分するときは、紙製シートからなる封筒本体と合成樹脂製シートからなるバブルシートとを切り離して分別処理することが必要となってきており、前述のようにバブルシートの全周は封筒本体の内面に対して熱溶着により完全に接合されていると、バブルシートを封筒本体から剥がしにくく、分別処理に手間取るという問題があった。
【0005】
【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、分別処理のための封筒本体とバブルシートとの分離を容易に行なえるようにすることを目的とするものである。
【0006】
【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、紙製シートからなる封筒本体の表側のシート部と裏側のシート部との間には合成樹脂製シートを材料としてエアをセル状に密閉して形成されたバブルシートが2枚重なった状態で挟まれ、内容物の出入口となる一端部を除く周囲3辺での3方シール部で熱溶着により止められてなる封筒において、前記3方シール部以外の残りの1つの辺において封筒本体の表側のシート部の内面に重なる一方のバブルシートの封筒を立てた状態における上端部である一端部と封筒本体の裏側のシート部の内面に重なる他方のバブルシートの封筒を立てた状態における上端部は同一高さであり、前記一方のバブルシートはその上端より少し下側位置で表側のシート部の内面に対し封筒の幅方向全長に亘って接着剤により接着固定されてはいるが熱接着されておらず、前記他方のバブルシートはその上端より少し下側位置で裏側のシート部の内面に対し封筒の幅方向全長に亘って接着剤により接着固定されてはいるが熱接着されていないことを要旨とするものである。
【0007】
この構成により、紙製シートからなる封筒本体の3方シール部以外の残りの1つの辺において表側のシート部の内面に重なる一方のバブルシートの一端部は表側のシート部の内面に対し接着剤により接着固定され、また裏側のシート部の内面に重なる他方のバブルシートの一端部も裏側のシート部の内面に対し接着剤により接着固定されていることにより、分別処理の際の表側のシート部からの一方のバブルシートの引き剥がしおよび裏側のシート部からの他方のバブルシートの引き剥がしを容易に行なうことができる。
【0008】
【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4において、1は紙製シートからなる封筒本体で、表側のシート部2と裏側のシート部3とからなり、表側のシート部2と裏側のシート部3との間には合成樹脂製シートを材料としてエアをセル状に密閉して形成されたバブルシート4,5が2枚重なった状態で挟まれ、一端(封筒を立てた状態における上端)を除く周囲3辺での3方シール部で熱溶着により止められている。6はその熱溶着部である。また、前記3方シール部以外の残りの1つの辺において封筒本体1の表側のシート部2の内面に重なる一方のバブルシート4の上端部は表側のシート部2の内面に対し接着剤により接着固定され、また3方シール部以外の残りの1つの辺において封筒本体1の裏側のシート部3の内面に重なる他方のバブルシート5の上端部は裏側のシート部3の内面に対し接着剤により接着固定されている。7はその接着部である。図面に示す実施の形態では表側のシート部2と一方のバブルシート4および裏側のシート部3と他方のバブルシート5との接着部7は封筒の幅方向全長に亘って設けられており、分別処理の際にバブルシート4および5の上端が摘み易いようにバブルシート4および5の上端より少し下側位置で接着されているが、接着部7を途中数箇所で分断しておいても分別処理の際にバブルシート4および5の上端が摘み易くなる。なお図中、8は封筒本体1の表側のシート部2の上端に連設されている折り返し片で、この折り返し片8の内面には粘着剤9が付設され、折り返し片8で封筒の上端を閉じない状態のときは粘着剤9は離型紙10により覆われている。
【0009】
上記構成において、封筒を使用後において廃棄処分するときは、紙製シートからなる封筒本体1と合成樹脂製シートからなるバブルシート4,5とを切り離して分別処理することが必要であり、そのとき本実施の形態では封筒の上端より指を入れてバブルシート4が接着されている表側のシート部2とバブルシート5が接着されている裏側のシート部3とを前記3方シール部の熱溶着部6で引き裂くように切り離し、その後、表側のシート部2からバブルシート4を前記接着部7から引き剥がすとともに、裏側のシート部3からバブルシート5を前記接着部7から引き剥がすことにより、紙製シートからなる封筒本体1と合成樹脂製シートからなるバブルシート4,5とが分別されることになる。このように本実施の形態では表側のシート部2とバブルシート4ならびに裏側のシート部3とバブルシート5との接合部の一部に前記接着部7を存在せしめ、表側のシート部2からのバブルシート4の引き剥がしおよび裏側のシート部3からのバブルシート5の引き剥がしを容易に行なえるようにしてある。
【0010】
【発明の効果】
以上のように本発明によれば、紙製シートからなる封筒本体の3方シール部以外の残りの1つの辺において表側のシート部の内面に重なる一方のバブルシートの一端部は表側のシート部の内面に対し接着剤により接着固定され、また裏側のシート部の内面に重なる他方のバブルシートの一端部も裏側のシート部の内面に対し接着剤により接着固定されていることにより、分別処理の際の表側のシート部からの一方のバブルシートの引き剥がしおよび裏側のシート部からの他方のバブルシートの引き剥がしを容易に行なうことができる。
