A sup - port structure supports the container and a drive assembly that advances the piston. The drive assembly includes a drive rib- bon that can be retracted and extended. The retracted ribbon defines a spiral and the extended ribbon defines a helix. The drive ribbon is incrementally moveable between the retracted 40 spiral configuration and extended helical configuration. A mechanical drive rotates the drive ribbon to selectively extend and retract the ribbon.
