Abstract
The rotatable cap of an end closure and the associated end closure base are provided with detent elements defining one rotative position out of the entire 360 degrees and allowing rotation up to such position from all other rotative positions throughout the entire 360 degrees. The detent may be in the form of a plug which is received in and closes the discharge opening of the closure to act as an anti-sifting element. Automatic orientation can be accomplished by simply engaging the cap with a friction member carried at the end of a power-driven spindle provided with a slip clutch while turning the spindle through at least one full turn.
