【００１９】
図１（ｂ）は、本発明の包装材の全体斜視図であり、二枚重ねフィルムＡ、及び前記延設部Ｂにおいては、その二枚重ねフィルムＡの前記一端部（図１（ａ）中では折目部５に相当）に直交する方向であって、互いに対向するそれぞれ外端部に、加熱、加圧により形成された密封シール部１１、１２と、密封シール部１３、１４とが設けられている。なお、二枚重ねフィルムＡの重ね合わせ内面、及び前記延設部Ｂの重ね合わせ内面には、熱融着の容易なシーラント層が設けられて、加熱、加圧により密封シールが可能となっている。
【００２０】
二枚重ねフィルムＡの前記一端部には折目部５による密封閉塞部を備え、該一端部の折目部５に平行な方向の延設部Ｂの外端部にも、折目部３による密封閉塞部を備えている。なお、本発明の包装材においては、前記折目部３、５部分の密封閉塞部は必ずしも折目部となっていなくてもよく、例えば、同図１（ｂ）に示すように、折目部３、５に相当する部分を二枚重ねフィルムの開放端部として、それを加熱、加圧して密封シール部１５を形成することにより密封閉塞部としたものでもよい。
【００２１】

【００２２】
本発明のチャック付き密封包装材及びチャック付き密封包装体は、図１（ｃ）に示すように、上記延設部Ｂのリニアーチャック７と、それに平行な方向の延設部Ｂ外端部の密封閉塞部（折目部３又は密封シール部１５）との間を仮想カッティングラインＣに沿ってカッティングすることにより、延設部Ｂ外端部の密封閉塞部を包装材本体から切り離した後、リニアーチャック７の凹凸嵌合を手指にて解除して包装物を開封して内容物を取り出すことができ、そして、嵌合を解除した前記リニアーチャック７を凹凸嵌合することにより、再度密封状態にすることができる。
【００２３】
本発明の包装材の上記延設部Ｂには、そのリニアーチャック７と、それに平行な方向の延設部Ｂ外端部の密封閉塞部（折目部３又は密封シール部１５）との間に、仮想カッティングラインＣに沿って、延設部Ｂの外端部の密封閉塞部を包装材本体から切り離しできるように、印刷によるカッティングマークや、そのマークの一端部に相当する部分の延設部Ｂの密封シール部１３又は密封シール部１４の外端部に切込部１７を形成してもよい。

【００２５】
本発明の包装材の二枚重ねフィルムＡとして使用する柔軟な合成樹脂フィルムとしては、例えば、ポリエチレンフィルム、ポリプロピレンフィルム、ポリエチレンテレフタレートフィルム、あるいは、これらのいずれかのフィルムとアルミ箔、紙シート、蒸着フィルムなどとの積層ラミネートによる複合フィルムが使用できる。
【００２６】
【発明の効果】
本発明のチャック付き密封包装材及びチャック付き密封包装体は、内容物を充填した後も全体形状が偏平形状であるが、チャック付き開封部分はその一端部になく、包装材の中央部分における延設部にあるため、包装材の延設部に設けたチャック付き開封部分の外端部にある密封閉塞部をカッティングラインに沿って切り離した後、その偏平な包装材をテーブル等に放置したり、あるいは電子レンジなどにて加熱調理したりして、不用意にチャックが開いた場合に、チャックの開封部分が偏平形状の包装材の一端部にある従来の場合と比較して、チャックの開いた部分から内容物が横漏れを起こすことを完全に回避でき、また、チャックは包装材の中央部分で開き、開く時に内容物の流動力が延設部の全体を起立させる方向に作用するため、従来よりも内容物の漏れ出しを少しでも減少でき、漏れ出しにより周囲を汚したりすることを減少又は回避することができるなどの効果がある。
【００２７】
また、本発明のチャック付き密封包装材は、チャック付きの開封部分が包装材の中央部にあるにも係わらず、内容物を充填するための開口部の位置は、包装材の中央部で無く、包装材の一端部にあるために、従来の袋状のチャック付き包装材への充填操作と同様に包装材の一端部からの充填が可能であって、従来のチャック付き包装材への充填に使用されている充填装置や充填ラインを用いた充填でも可能であり、内容物の充填操作が容易且つ能率的に実施できるなどの効果がある。
