Dispensing cap for attaching to a container

A delivery system having a dispensing cap for attaching to a container, said dispensing cap comprising:

• (a) a dispensing chamber having an interior compartment for holding an ingredient to be dispensed into the container and having a top end and a lower end, wherein the top end of said dispensing chamber has a flexible diaphragm and an actuator button disposed on said flexible diaphragm;
• and wherein the lower end of said dispensing chamber is connected to an s-shaped frangible membrane member;
• (b) said dispensing chamber including a threaded bottle cap for attaching said dispensing cap to the container, said threaded bottle cap being disposed around the outer wall of said dispensing chamber so that at least two thirds of the length of said dispensing chamber is disposed below said threaded bottle cap, and in the container;
• (c) a piercing shaft having a top end fixedly attached to said diaphragm and a bottom tip at the bottom end of said piercing shall, such that said actuator button and said piercing shaft are axially aligned, said piercing shaft further including four (4) substantially rectangular shaped vanes having a lower end which has a v-shaped tip which engages the center of said s-shaped frangible membrane at a right angle;
• and
• (d) said flexible diaphragm being movable downwardly from an ingredient housing position to an ingredient dispensing position by pushing both of said actuator button and said piercing shaft downwardly towards the center of said s-shaped frangible membrane which thereby causes the v-shaped tip of said piercing shaft to apply pressure at a right angle to the center of said s-shaped frangible membrane to pierce it, and thereby causing said s-shaped frangible membrane to rupture from the center outwardly, and thereby form a dispensing opening in the interior compartment of said dispensing chamber so that the ingredient housed within the compartment of said dispensing chamber freely passes through said dispensing opening and into the container.
