Abstract
【解決手段】カニューレを、封止体111を含むオーバーキャップ103に回転不能に取り付け構成する。他には、封止体をオーバーキャップ内にオーバーモールドするか、又は、カニューレとオーバーキャップとの間に固定された薄膜を備えるように回転不能に構成する。また、カニューレとオーバーキャップとは、タブとスロットとの結合107、109による恒久的にスナップ結合させ、カニューレやオーバーキャップを損傷せずに分離することができないようにする。また、ベントカニューレ(ベントと摩擦係合するための窪みを備えてもよい)を、封止体のスリット113内に受け入れられるように構成し、カニューレを通して流体を眼から排出することができるようにする。
