ABSTRACT:
A closure assembly for a filler neck having a mouth and an inner mounting flange coupled thereto, wherein a closure for the mouth of the filler neck is provided with a body and an inner retainer fixed to the body. The inner retainer having a rigid portion and a cantilevered flexible portion and wherein rotation of the closure initially causes the rigid portion of the retainer to engage the flange so that the closure member is retained by the flange and continued rotation causes the cantilevered flexible portion to be deflected axially downward with respect to the axis of rotation of the closure, without radial movement toward the axis of rotation and to subsequently release the flexible portion to allow the flexible portion to move back to a undeflected position where a detent on the flexible portion enters a notch in the inner mounting flange to restrain relative rotation between the flange and retainer.
