Description
デバイスは、ハンドル内にある穿孔ピンをさらに含んでいてもよく、穿孔ピンは、容器のシールを穿孔するように構成されている。
インジケータは、環状部材を含み、インジケータは、インジケータが第1の位置と第2の位置との間で移動する際に、ハンドルおよび容器に対して移動するように構成されている。
インジケータの直径は、容器の外径よりも大きく、かつハンドルの内径よりも小さくてよい。
加圧流体は、1つまたは複数のばねのばね力に打ち勝って、インジケータを第1の位置から第2の位置に移動させるように構成されていてもよい。
インジケータは、加圧流体が流体経路を通って流れる場合にハンドルの半径方向外向きの方向に移動するように構成された突起を含んでいてもよい。
デバイスは、デバイスの下流端から流体を放出するように構成されたアクチュエータをさらに含んでいてもよく、アクチュエータは、インジケータが第2の位置にある場合にのみ作動可能であるように構成されていてよい。
別の態様によれば、加圧流体を送達するためのデバイスは、ハンドルと、ハンドルの開口部を閉じるように構成されたキャップと、キャップに取り付けられたインジケータとを含み、インジケータは、キャップがハンドルに取り付けられた場合にハンドルに対して移動するように構成されたリング状部材を含み、インジケータは、ハンドルの流体経路への流体収容容器の接続を示すように構成されている。
キャップおよびインジケータは、各々、ハンドルに対して回転するように構成されていてよい。
