Affixable dispensing capsule

A dispensing capsule for affixing to an opening of a receiving container having a liquid compartment therein, wherein the dispensing capsule comprises

• a housing having a cavity therein for separately hermetically storing preloaded contents within the cavity when the dispensing capsule is disposed in a closed position, the housing further comprising:
• a breakaway plunger, and
• a base plate having an aperture, and a diaphragm including a diaphragm button
• wherein
• the breakaway plunger and base plate cooperate to form a seal between the cavity and the liquid compartment of the receiving container, and
• the housing, base plate and breakaway plunger are all constructed from a single injection molding.

A dispensing capsule for affixing to an opening of a receiving container where

• the dispensing capsule comprises a housing having a cavity therein for separately hermetically storing preloaded contents within the cavity when the dispensing capsule is disposed in a closed position,
• the housing of the dispensing capsule further comprises
• a breakaway plunger and a base plate having an aperture that cooperate to form a seal between the cavity and a liquid compartment of the receiving container, and
• a shaft that is connected at one end to the breakaway plunger and at an opposing second end to a diaphragm, and
• an activating force applied to the shaft causes the dispensing capsule to be disposed in an open position such that
• the breakaway plunger disengages from the base plate to break the seal,
• the breakaway plunger fully detaches at its periphery while remaining attached to the shaft such that it does not fall into the liquid compartment, and
• the breakaway plunger is thrust toward the receiving container, thereby creating liquid communication between the fluid compartment and cavity such that the preloaded contents of the cavity are discharged through the aperture of the base plate into the communicating liquid compartment of the receiving container and the breakaway plunger and the shaft remain connected to the diaphragm.

A dispensing capsule for affixing to an opening of a receiving container where

• the dispensing capsule comprises a housing having a cavity therein for separately hermetically storing preloaded contents within the cavity when the dispensing capsule is disposed in a closed position,
• the housing of the dispensing capsule further comprises
• a first portion comprising
• a cup,
• a breakaway plunger having a central axis and a base plate having an aperture that cooperate to form a seal between the cavity and a liquid compartment of the receiving container, and
• a shaft that is connected at one end to the breakaway plunger,
• a second portion comprising a lid having a diaphragm, a diaphragm button, a seal and a shaft guide such that the shaft guide guides the lid onto the shaft and removably affixes the lid to the shaft thereto,
• wherein an activating force applied to the shaft causes the dispensing capsule to be disposed in an open position such that
• the breakaway plunger disengages from the base plate to break the seal,
• the breakaway plunger fully detaches at its periphery while remaining attached to the shaft such that it does not fall into the liquid compartment, and
• the breakaway plunger is thrust toward the receiving container, thereby creating fluid communication between the liquid compartment and cavity such that the preloaded contents of the cavity are discharged through the aperture of the base plate into the communicating liquid compartment of the receiving container and the shaft remains affixed to the lid.

A dispensing capsule where the dispensing capsule comprises a housing having a cavity therein for hermetically storing preloaded contents within the cavity when the dispensing capsule is disposed in a closed position,

• the housing of the dispensing capsule further comprises a breakaway plunger having a central axis and a base plate having an aperture that cooperate to form a seal that holds the preloaded contents in the cavity,
• the housing further comprises a diaphragm and a diaphragm button integral to the diaphragm and disposed in concentric axial alignment with the breakaway plunger and a shaft having a central axis that is fixedly connected at one end to the diaphragm button and at the opposing end to the breakaway plunger, wherein the breakaway plunger comprises a substantially circular periphery and the shaft is concentrically disposed with respect to the periphery such that the central axis of the shaft is substantially perpendicularly disposed to a plane formed of the periphery,
• the housing further comprises a plurality of stress concentrators symmetrically disposed about the central axis of the breakaway plunger, wherein each of the plurality of stress concentrators comprises a substantially planar structure disposed substantially perpendicularly to the plane formed by the periphery with the substantially planar structure structurally attached to the breakaway plunger and spanning at least a portion of the breakaway plunger and terminating at the periphery, and
• an activating force applied to the diaphragm button causes the dispensing capsule to be disposed in an open position such that the breakaway plunger disengages from the base plate to break the seal and the breakaway plunger is thrust outwardly from the aperture, thereby creating an opening according to the magnitude of stress generated at each stress concentrator with a predictable breakaway pattern such that the preloaded contents of the cavity are discharged through the aperture of the base plate and there is no relative movement between the diaphragm and the diaphragm button and the diaphragm creates a flexible volume of the cavity such that an excessive pressure in the sealed cavity is relieved.
