A screw cap for a container equipped with a threaded neck is provided and the cap supports an applicator shank therefrom for limited axial shifting and rotation relative to the cap. The applicator shank is spring biased to a position of maximum extension relative to the open end of the cap and is equipped with an abutment disc for abutting the outer end of the associated container threaded neck for partially retracting the shank in response to threaded engagement of the cap with the container neck. The applicator shank is of an length to extend to the bottom of the container when the disc is abutted against the outer end of the container neck and the shank may be extended relative to the cap to a position with the abutment disc disposed slightly outwardly of the open end of the cap when the cap is disengaged from the container neck.
