an axial movable cap attached to the shell and moveable along the inner guide, the cap having a chamber therein adapted to hold a unit dosage of material to be dispensed into the container;
a sealing layer coupled to the cap, wherein the chamber is sealed with the sealing layer extending across a lower open end of the cap, wherein axial movement of the cap along the inner guide will cause the sealing layer to rupture or be removed to dispense the contents of the chamber into the container; and
