Description
厚さ0.3mmの軟質塩化ビニルシートを縦260mm、横320mmの直角四辺形に切り取った。切り取った1枚のシートには、上部に図1に示したように注入口2を設け、下部には排出口3を設けるとともに、注入口より上方に通気孔6を設けてシートLとした。切り取った別の同様なシートには、注入口も排出口も通気孔も設けないで、シートMとした。シートMの上にシートLを重ねて、シートの周縁を加熱溶融し、幅約3mmの接着部分1を全周にわたって形成し、図1に示したような構造の廃液バッグRを作った。
上述の液体容器に空気を圧入して容器を膨らませ、膨らんだ容器を水中に沈めて接着部分からの空気漏洩を測定し、容器を水中から取り出してエアーガンで付着水を飛散させて、大雑把に水分を取り除くまでに約25秒を要した。しかし、製品とするまでにはさらに容器を乾燥させる必要があって、その乾燥には約30分を要した。
この比較例は公知の方法ではないが、念のために実施した。この比較例は、実施例1の方法において、膨張制限枠を使用しない点で異なるだけとした。すると、検体及び標準容器内の空気圧が25Kpaとなるまでに、加圧空気を約25秒間にわたって圧入する必要があった。このときの液体容器の膨らみ幅は135mmとなった。従って、比較例2では空気の圧入時間が実施例1よりも16秒も余計に必要とされ、また空気の排出にも同程度の余分な時間が必要となり、検査を実施するのに実施例1よりも長い時間を要した。

Claims (1)
- 柔軟なシートを接着して作られた偏平な袋状のものからなり、上部に通気孔を持った液体容器について、接着部分からの液体漏洩の有無を検査するにあたり、検査すべき液体容器のほかに、その容器と同種の容器であって空気漏洩のない標準容器を用意し、感圧性粘着剤を予め塗布した不透性フィルムを上記液体容器の通気孔に貼付して通気孔を塞いだものを検体とし、検体と標準容器とをそれぞれ同じ膨らみに制限する膨張制限枠に入れ、両容器に同一条件の下で空気を圧入し、両容器を何れも上記枠によって膨張を抑えられた状態に維持し、その後にそれぞれの容器内の空気圧を測定し、空気の圧力差が許容範囲内にあるとき、液体漏れがないと判定することを特徴とする、液体容器の検査方法。
