Abstract
A device suitable for use as an intra vaginal device or as a bolus where, after initiation, a member (usually a plunger) moves with a known movement characteristic and is involved in the stagger release of multiple materials. That moving member is used to time the discharge of one or more material from its reservoir in the device (there being separate powering of the timed discharge) or is used to both time and indirectly power the discharge of one or more material from its reservoir, such discharges preferably being in a staggered manner. Optionally the moving member as a plunger may itself also directly discharge a material from a reservoir.
