Description

【０００１】
【発明の属する技術分野】
本発明は被包装物を包む合成樹脂製の緩衝包装袋を用いた包装構造に関するものである。
【０００２】
【従来の技術】
従来、横方向に連続して多数の区画された密封袋部の全てに１箇所から空気を充填できるとともに、密封袋部に充填された空気は密封袋部から抜け出ないように各密封袋部に逆止弁が設けられ、何れかの密封袋部が破損しても空気の流出はその破損した密封袋部からだけとなるように合成樹脂フィルム製シートを材料として構成された緩衝材が知られている。そして、このような緩衝材を用いて作られた緩衝包装袋が知られている。
【０００３】
図１１〜図１２にこの緩衝包装袋ならびにこの緩衝包装袋により被包装物を包んだ状態を示し、緩衝包装袋１は横方向に連続して多数の区画された長尺状の同じ大きさの密封袋部２を備え、この全ての密封袋部２に１箇所から空気を充填できるとともに、各密封袋部２に充填された空気が密封袋部２から抜け出ないように各密封袋部２に逆止弁（図示せず）が設けられ、何れかの密封袋部２が破損しても空気の流出はその破損した密封袋部２からだけとなるように合成樹脂フィルム製シートを材料として構成された緩衝材により作られている。
【０００４】
さらに詳しくは、前記緩衝包装袋１の材料となる緩衝材は長尺状の密封袋部２が多数並んでおり、緩衝材が筒状となるように密封袋部２が長さ方向に折り曲げられて、多数並んでいる密封袋部２の両端に位置する密封袋部２の部分に形成される開口部を溶着により閉じることによって折り曲げ方向における緩衝材の端部間に被包装物の挿入口３が形成された緩衝包装袋１が作られている。４は多数並んでいる密封袋部２の両端に位置する密封袋部２での溶着部である。
【０００５】
このようにして作られた緩衝包装袋１には前記挿入口３より被包装物５が挿入されて空気が充填された多数の密封袋部２によって被包装物５を保護するようになっている。
【０００６】
しかしながら、被包装物５に付属品が別個に存在する場合があり、その場合付属品を別の緩衝包装袋に収納するなどの必要があった。
【０００７】
【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、上記のような連続して多数の区画された長尺状の同じ大きさの密封袋部を備え、この密封袋部に１箇所から空気を充填できるとともに、密封袋部に充填された空気が密封袋部から抜け出ないように密封袋部に逆止弁が設けられ、何れかの密封袋部が破損しても空気の流出は他の密封袋部におよばないように合成樹脂製の緩衝包装袋と紙製の筒状スリーブあるいは合成樹脂製袋を用いて、被包装物と必要に応じて付属品を効率良く包装できるようにすることを目的とするものである。
【０００８】
【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、横方向に連続して多数の区画された長尺状の密封袋部に１箇所から空気を充填できるとともに、空気が充填された密封袋部はそれぞれ独立して密封状態を保持するように構成された合成樹脂フィルム製シートからなる緩衝材を用い、この緩衝材が筒状となるように密封袋部が長さ方向に折り曲げられて、多数並んでいる密封袋部の両端に位置する密封袋部の部分に形成される開口部を溶着により閉じることによって折り曲げ方向における端部間に被包装物の挿入口が形成されるように構成した緩衝包装袋であって、前記各密封袋部には、その長さ方向一端側に形成されている空気注入路の一端の空気注入口から空気を充填できるとともに、当該密封袋部に充填された空気が抜け出ないように各密封袋部の長さ方向一端の空気注入路側に逆止弁が設けられ、この逆止弁により各密封袋部は個別に密封されるように構成し、前記緩衝材は、筒状となるように密封袋部が長さ方向に折り曲げられたとき、緩衝包装袋が側面形状においてほぼ矩形となり、しかも被包装物の厚みに適した緩衝包装袋の収納空間部の深さが得られるように各密封袋部の長さ方向適所に折り曲げ用の部分溶着部が形成されており、前記各密封袋部に空気を充填して膨らませた際に、当該密封袋部により膨らんだ部分を構成する前記緩衝包装袋の一部に、前記空気注入口からの空気が注入されないように形成されて空気が溜まらない部分を設けるか、あるいは空気が充填されるがその部分の密封袋部の外径は他の部分に比べて小さくなるようにして、緩衝包装袋の外表面に凹部を形成するようにしたことを要旨とするものである。また本発明は、上記構成の緩衝包装袋を筒状スリーブもしくは合成樹脂製袋で外側から覆うように構成したことを要旨とするものである。さらに本発明は、緩衝包装袋の凹部の外側位置における筒状スリーブもしくは合成樹脂製袋の一部に窓部を設けたことを要旨とするものである。
【０００９】
この構成により、緩衝包装袋の一部に空気が溜まらない部分を設けるか、あるいは空気が充填されるがその部分の密封袋部の外径は他の部分に比べて小さくなるようにして、緩衝包装袋に凹部を形成するようにした点に最大の特徴があり、この凹部に付属品を収納したり、印刷が施されたラベルを貼り付けるなどすることが可能となる。また、緩衝包装袋の一部に空気が充填されるがその部分の密封袋部の外径は他の部分に比べて小さくなるような構成を採用することにより、緩衝包装袋の受圧面積の調整が可能となる。そして、この緩衝包装袋と紙製の筒状スリーブあるいは合成樹脂製袋を用いて、被包装物と必要に応じて付属品を効率良く包装できるものである。また、前記筒状スリーブあるいは合成樹脂製袋の一部に透明な窓部を設けることにより、内容物を外から確認することができる。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態について、図面に基づいて説明する。
（実施の形態１）
先ず、図１〜図６に示す実施の形態１について説明する。図１において、１０は本実施の形態の緩衝包装袋の基体となる緩衝材で、この緩衝材１０は２枚の合成樹脂フィルム製シート材の外周部１０ａを加熱して溶着するとともに、一定間隔で横方向に設けられた区画溶着部１０ｂにより横方向に連続して多数の区画された長尺状の同じ大きさの密封袋部１２を備え、この密封袋部１２に密封袋部１２の長さ方向一端側に形成されている空気注入路１３の一端の空気注入口１３ａから空気を充填できるとともに、密封袋部１２に充填された空気は密封袋部１２から抜け出ないように各密封袋部１２の長さ方向一端の空気注入路１３側に逆止弁１４（詳細説明は省略する）が設けられ、空気を充填後は何れかの密封袋部１２が破損しても空気の流出はその破損した密封袋部１２からだけとなるように構成されている。この緩衝材１０は折り曲げられ、且つ加熱溶着することにより緩衝包装袋１１（図２以下参照）を構成するが、その緩衝包装袋１１の所望の厚み、形状に対応させるべく、各密封袋部１２の長さ方向適所に折り曲げ用の部分溶着部１７ａが形成されている。また、後述する被包装物１８を挿入する折り曲げ用の部分溶着部１７ｂが形成されている。さらに、密封袋部１２における中央部の密封袋部１２−Ａには空気を充填しないように、空気注入路１３側に溶着部１０ｃが形成されている。
【００１１】
以上のように構成された緩衝材１０を用いて図２に示すような緩衝包装袋１１を構成する。即ち、緩衝材１０が筒状となるように密封袋部１２が長さ方向に折り曲げられて、多数並んでいる密封袋部１２の両端に位置する密封袋部１２の部分に形成される開口部１１ａをその端縁部における溶着部１６を加熱溶着して閉じることによって、折り曲げ方向における緩衝材１０の端部間に被包装物の挿入口１５が形成された緩衝包装袋１１が作られている。なお、緩衝材１０が筒状となるように密封袋部１２が長さ方向に折り曲げられたとき、緩衝包装袋１１が側面形状においてほぼ矩形となり、しかも被包装物の厚みに適した緩衝包装袋１１の収納空間部の深さが得られるように各密封袋部１２の長さ方向適所に前述した折り曲げ用の部分溶着部１７ａが形成されている。
【００１２】
ところで、前記多数並んでいる密封袋部１２の内、中央に位置する２本の密封袋部１２−Ａは、その長さ方向一端が溶着部１０ｃにより閉じられて空気が充填されないような構成となっており、緩衝包装袋１１に前記空気注入路１３の一端から空気を充填したとき、多数並んでいる密封袋部１２の内、中央に位置する２本の密封袋部１２−Ａは膨らまず、偏平な状態のままとなり、緩衝包装袋１１の天面および底面に凹部１９および２０が形成されるように構成されている。
【００１３】
図３に空気が充填されて平面形状が膨らんでほぼ矩形状となった緩衝包装袋１１を示し、この緩衝包装袋１１を図４に示すように折り曲げ用の部分溶着部１７ｂで外側に折り曲げることにより、前記挿入口１５を開いて被包装物１８を挿入し、挿入口１５を元の状態に閉じた状態で、図５に示すように緩衝包装袋１１の天面および底面における凹部１９および２０に付属品２１および２２を収め、その状態で緩衝包装袋１１および付属品２１，２２を包むように紙製の筒状スリーブ２３を被せ、筒状スリーブ２３の両端開口部のほぼ中央を粘着テープ２４で塞ぐことにより図６に示す包装完了状態となる。
【００１４】
この包装完了状態において、被包装物１８は空気が充填された多数の密封袋部１２によって保護されることになる。
なお、紙製の筒状スリーブ２３の代わりに、厚紙もしくは段ボール板からなる包装箱を用いて、この包装箱に緩衝包装袋１１および付属品２１，２２を収納するようにしても良い。
【００１５】
ところで、実施の形態１では密封袋部１２に充填された空気は密封袋部１２から抜け出ないように各密封袋部１２の長さ方向一端に逆止弁１４が設けられ、空気が充填された密封袋部１２がそれぞれ独立して密封状態を保持するように構成されているが、逆止弁１４を設けずに、多数の区画された密封袋部１２に空気注入路の一端から空気を充填した後、密封袋部１２の長さ方向一端を溶着により閉じるようにしても良い。また、緩衝包装袋１１に凹部１９および２０を形成する密封袋部１２−Ａは、溶着部１０ｃにより空気が空気注入路１３から注入されない構成としたが、予め孔をあけて空気が溜まらないようにしても良い。
【００１６】
（実施の形態２）
次に、図７および図８に示す実施の形態２について説明すると、前記実施の形態１では緩衝包装袋１１に被包装物１８を挿入し、緩衝包装袋１１の天面および底面における凹部１９および２０に付属品２１および２２を収めた状態で緩衝包装袋１１および付属品２１，２２を紙製の筒状スリーブ２３で包んでいるが、実施の形態２では筒状スリーブ２３の代わりに、紙製または合成樹脂フィルム製シートからなる袋２５を用い、緩衝包装袋１１に被包装物１８を挿入し、緩衝包装袋１１の天面および底面における凹部１９および２０に付属品２１および２２を収めた状態で緩衝包装袋１１および付属品２１，２２を袋２５の中に収納し、再封緘可能とするために繰り返し開閉自在な粘着剤が付着された一端開口部２６より袋２５に対する内容物の出し入れを行なえるようにしてある。ところで、この実施の形態２において使用される緩衝包装袋１１は前記実施の形態１と同じである。なお、この実施の形態２において袋２５にはほぼ全面に印刷が施されるが、袋２５の天面のほぼ中央を印刷のない透明な窓部２７を設けておくことにより、内容物を袋２５の外から確認できるようになっている。
【００１７】
（実施の形態３）
次に、図９および図１０に示す実施の形態３について説明すると、前記実施の形態１では緩衝包装袋１１の中央に位置する２本の密封袋部１２−Ａは膨らまず偏平なままとなるように構成され、緩衝包装袋１１の全周に亘って凹部が形成されているが、実施の形態３は中央に位置する３本の密封袋部１２−Ｂの長さ方向のほぼ中央、つまり緩衝包装袋１１を形成した場合、その挿入口１５が形成されている面とは反対側の面のほぼ中央にのみ凹部２８が形成されるようになっている。前記挿入口１５が形成されている面を下に向けた場合、凹部２８が形成されている面は天面となる。
【００１８】
以下、その詳細について述べると、緩衝包装袋１１の天面のほぼ中央にあたる位置の前記中央に位置する３本の密封袋部１２−Ｂの長さ方向のほぼ中央において３本の密封袋部１２−Ｂの内部を長さ方向に沿って２〜４本程度に仕切る溶着部２９を設けてある。このように、緩衝包装袋１１の天面のほぼ中央にあたる位置の前記中央に位置する３本の密封袋部１２−Ｂの長さ方向のほぼ中央は３本の密封袋部１２−Ｂの内部が長さ方向に沿って溶着部２９によって２〜４本程度に仕切られているので、空気が充填されて膨らんだ状態において前記中央に位置する３本の密封袋部１２−Ｂの長さ方向のほぼ中央の外径は他の部分に比べて小さく、緩衝包装袋１１の天面のほぼ中央にのみ凹部２８が形成されるようになっている。そして、この凹部２８に付属品３０を収めた状態で緩衝包装袋１１および付属品３０を包むように前記実施の形態１と同様に紙製の筒状スリーブを被せるか、あるいは前記実施の形態２と同様に袋の中に収納することにより包装が完了する。なお、緩衝包装袋１１および付属品３０を実施の形態２と同様に袋の中に収納する場合、実施の形態２のように天面のほぼ中央に印刷のない透明な窓部を設けた袋を用いることも可能で、その場合、前記凹部２８に付属品３０を収めずに、凹部２８の底部に印刷されたラベルを貼り付けておくようにしても良い。
【００１９】
【発明の効果】
以上のように本発明によれば、横方向に連続して多数の区画された長尺状の密封袋部に１箇所から空気を充填できるとともに、空気が充填された密封袋部はそれぞれ独立して密封状態を保持するように構成された合成樹脂フィルム製シートからなる緩衝材を用い、この緩衝材が筒状となるように密封袋部が長さ方向に折り曲げられて、多数並んでいる密封袋部の両端に位置する密封袋部の部分に形成される開口部を溶着により閉じることによって折り曲げ方向における端部間に被包装物の挿入口が形成されるように構成した緩衝包装袋であって、前記各密封袋部には、その長さ方向一端側に形成されている空気注入路の一端の空気注入口から空気を充填できるとともに、当該密封袋部に充填された空気が抜け出ないように各密封袋部の長さ方向一端の空気注入路側に逆止弁が設けられ、この逆止弁により各密封袋部は個別に密封されるように構成し、前記緩衝材は、筒状となるように密封袋部が長さ方向に折り曲げられたとき、緩衝包装袋が側面形状においてほぼ矩形となり、しかも被包装物の厚みに適した緩衝包装袋の収納空間部の深さが得られるように各密封袋部の長さ方向適所に折り曲げ用の部分溶着部が形成されており、前記各密封袋部に空気を充填して膨らませた際に、当該密封袋部により膨らんだ部分を構成する前記緩衝包装袋の一部に、前記空気注入口からの空気が注入されないように形成されて空気が溜まらない部分を設けるか、あるいは空気が充填されるがその部分の密封袋部の外径は他の部分に比べて小さくなるようにして、緩衝包装袋の外表面に凹部を形成するようにしたので、前記凹部に付属品を収納したり、印刷が施されたラベルを貼り付けるなどすることが可能となる。また、緩衝包装袋の一部に空気が充填されるがその部分の密封袋部の外径は他の部分に比べて小さくなるような構成を採用することにより、緩衝包装袋の受圧面積の調整が可能となる。そして、この緩衝包装袋と紙製の筒状スリーブあるいは合成樹脂製袋を用いて、被包装物と必要に応じて付属品を効率良く包装できるものである。また、前記筒状スリーブあるいは合成樹脂製袋の一部に透明な窓部を設けることにより、内容物を外から確認することができる。
