Patent ID: 8443970

Claim:
A dispensing capsule for affixing to a mouth of a receiving container, said dispensing capsule comprising: a) a base including a generally conical shaped base plate having a concentrically disposed frangible membrane having an upper surface and a lower surface and at least one elongated tear line having a reduced thickness; b) a cup comprising a circular diaphragm functioning as a top wall, said cup including a shoulder disposed at a periphery of the diaphragm with said shoulder protruding above the entirety of said diaphragm and a side wall extending downwardly therefrom to create an opening at an opposing end thereof and defining a cavity on an interior of the cup, and further including a diaphragm button concentrically disposed on said diaphragm; and c) a stake having a stake base fixedly attached to said diaphragm and a tip opposingly disposed from said stake base such that said diaphragm button and stake are axially aligned, said stake further including at least one stress concentrating rib extending in an abaxial relation with respect to said at least one elongated tear line; wherein said cup and said base are affixed to one another such that frangible membrane is opposingly disposed from said diaphragm button and said base plate is in contacting engagement with said side wall of said cup to form an assembled dispensing capsule wherein said base plate forms a bottom wall which, together with said interior of said cup, defines a sealed cavity adapted to hold and store a predetermined ingredient within said sealed cavity; and wherein said diaphragm is movable to an ingredient dispensing position by pushing said diaphragm button toward said frangible membrane which thereby causes said stake and said at least one stress concentrating rib to apply a pressure against said frangible membrane abaxially of said at least one tear line and thereby causing said at least one tear line to break and create an opening in said sealed cavity wherethrough an ingredient located within said cavity may freely pass.
