PROBLEM TO BE SOLVED: To provide a connector which is easily fastened by twisting less than a turn by anyone without shifting the hold on the connector to fix on the mouth part of a container.SOLUTION: In the connector 1 which is screw-fastened to the mouth part 30 of the container having a screw line 31 with a cut part 50 on the external surface and is equipped with a through-hole for communicating with a space inside the mouth part of the container while being screw-fastened to the mouth part 30 of the container, a screw line 7 is formed for 360 degrees or more on the internal surface wall of the connector 1. When the connector 1 is fastened to the mouth part 30 of the connector by twisting, the screw line 7 of the connector 1 engages the screw line 31 of the mouth part 30 of the container mutually between 180 degrees and 270 degrees. A protruding part 7a which protrudes upward for engaging the cut part 50 formed on the screw line 31 of the mouth part of the container when completing to fasten by twisting is formed on the screw line 7 of the connector 1.COPYRIGHT: (C)2009,JPO&INPIT【課題】持ち変えることなく、誰でも1周未満の回転で容易に容器口部に巻き締め固定することが可能なコネクタを提供する。【解決手段】外面に切欠き部50を有する螺条31が形成された容器口部30に螺子締結され且つ容器口部30に螺子締結された状態で容器口部内空間と連通する貫通口を供えたコネクタ1において、コネクタ1の内面壁には、螺条7が360度以上にわたって形成されており、コネクタ1を容器口部30に巻き締めたとき、コネクタ1の螺条7と容器口部30の螺条31とは、180度乃至270度にわたって互いに係合しており、且つコネクタ1の螺条7には、巻き締め終了時において、容器口部の螺条31に形成された切欠き部50に係合する上方に突出した突起部7aが形成されている。【選択図】図5
