Abstract
A bottle cap is adapted to retain a quantity of an additive, such as for example aspirin or the like. The additive is retained in an isolated condition within a sealed chamber or within a bladder inside the bottle cap but in fluid communication with the liquid within the bottle, such as water. A cap with at least one downward extending protrusion is provided to breech the seal of the chamber or the bladder, thereby releasing some or all of the additive retained within the bottle cap.
