    • A gasket retaining cap member, and method of forming same, comprising an integral cap member having a downwardly extending annular flange forming an exterior cap wall and a downwardly extending annular retention wall spaced radially inward of the cap wall thereby forming a ring-shaped well therebetween into which a gasket member is placed and thereafter held securely in position by deformation of the retention wall. The method of forming the gasket retaining cap member comprises positioning the cap member, with the gasket placed inside, within a heat staking press which operates to stake deformation into the upper surface of the retention wall thereby causing the retention wall to partially overlie the gasket member and hold it securely in place.
    • 垫圈保持盖构件及其形成方法包括一体式盖构件,其具有向下延伸的环形凸缘,该环形凸缘形成外盖和围绕帽壁径向向内间隔的向下延伸的环形保持壁,从而在其间形成环形孔 垫圈构件被放置在其中,然后通过保持壁的变形牢固地保持在适当的位置。 形成垫圈保持盖构件的方法包括将盖构件定位在放置在内部的垫圈内的热铆钉压机中,该加热压力机操作以将变形进入到保持壁的上表面中,从而使保持壁部分地覆盖垫圈构件 并将其牢固地固定到位。
