A dispensing capsule has a diaphragm button, stake and frangible membrane for a system for selectively dispersing the contents of a cup into an attached bottle. A frangible membraned cup has a diaphragm button operably attached to a stake with the stake's sharp point at one end and the diaphragm button on the opposing end. A cavity is disposed in the cup for consumable product defined by side walls and a base plate. Preloaded ingredients contained within the hermetically sealed cup are discharged from the dispensing capsule into a bottle by simply depressing a button disposed on the diaphragm of the cup, thereby actuating the stake to thrust forward and apply concentrated pressure abaxially to the frangible membrane. This concentrated pressure pierces substantially the center of the frangible membrane, causing it to rupture and progressively opening it. The diaphragm button locks in this downward position, holding the stake into the opened frangible membrane to maintain the opening, permitting the contents to flow through the frangible membrane and exit the cavity of the cup.
