Abstract
A cap assembly for receiving a stopper and for application to the threaded neck of a bottle. The cap assembly includes a cap and a thrust washer. The cap has an end wall which has a central aperture and a circular side wall which has internal threads. The thrust washer has a base wall with a central aperture and a side wall which has a ridge at its outer end. The thrust washer lies within the side wall of the cap so that the base wall engages the end wall and the side wall extends through the aperture in the end wall and the ridge engages the outer surface of the end wall to retain tile thrust washer on the cap. Tile side wall of the thrust washer is resiliently yieldable to enable the ridge to disengage from the end wall to release the thrust washer from the cap.
