An additive dispensing system for a refrigerator that includes a reservoir configured to contain an additive and an additive outlet in fluid communication with the reservoir. The additive dispensing system is configured to be connected to a refrigerator and is operable to selectively dispense an amount of additive to water dispensed from the refrigerator. The additive dispensing system may be connected to a water filtration system of the refrigerator such that the additive dispensing system may dispense the amount of additive into filtered water dispensed from the refrigerator.

1. An additive dispensing system for a refrigerator, comprising: a receptacle comprising a pump action device, said pump action device comprising a surface having an aperture disposed within said surface and an annular protrusion surrounding said aperture; anda disposable cartridge slidably mounted
1. An additive dispensing system for a refrigerator, comprising: a receptacle comprising a pump action device, said pump action device comprising a surface having an aperture disposed within said surface and an annular protrusion surrounding said aperture; anda disposable cartridge slidably mounted within the receptacle, said disposable cartridge comprising: a reservoir,a bladder disposed within said reservoir, said bladder containing an additive,an inlet check valve, anda diaphragm in cooperation with said inlet check valve to define a dose chamber in fluid communication with said bladder, said diaphragm comprising an additive outlet check valve in fluid communication with said dose chamber,wherein said additive outlet check valve includes a pair of sealing surfaces,wherein said disposable cartridge does not include any surfaces in its fluid path downstream of said pair of sealing surfaces;wherein said disposable cartridge slides within said receptacle such that said annular protrusion depresses said diaphragm and causes said additive outlet check valve to open and said dosing chamber to reduce in volume, forcing additive through said additive outlet check valve and dispensing additive from said additive dispensing system. 2. The additive dispensing system according to claim 1, wherein said disposable cartridge is connected to a refrigerator. 3. The additive dispensing system according claim 1, wherein said receptacle is connected to a fixture located adjacent to a refrigerator. 4. The additive dispensing system according to claim 1, wherein said receptacle is connected to a refrigerator. 5. The additive dispensing system according to claim 1, wherein said receptacle is removably connected to a refrigerator. 6. The additive dispensing system according to claim 1, wherein said receptacle is connected to a refrigerator such that said additive outlet check valve is substantially adjacent to an outlet of a water filtration system of the refrigerator. 7. The additive dispensing system according to claim 1, wherein said additive dispensing system comprises a means for removably connecting the disposable cartridge to a refrigerator. 8. The additive dispensing system according to claim 1, wherein said receptacle further comprises a space and a guide configured to receive and hold said disposable cartridge within said space such that said disposable cartridge may move within said receptacle. 9. The additive dispensing system according to claim 1, wherein said disposable cartridge is operable to selectively dispense the amount of additive from said bladder, through said inlet check valve and out of said additive outlet check valve through manual manipulation of said disposable cartridge causing said disposable cartridge to move within said receptacle. 10. The additive dispensing system according to claim 1, wherein said bladder, inlet check valve, diaphragm and additive outlet check valve define a fluid flow path that runs parallel along a longitudinal axis of said disposable cartridge. 11. The additive dispensing system according to claim 1, wherein said inlet valve is an umbrella valve, and said additive outlet check valve is a duckbill valve. 12. An additive dispensing system for a refrigerator, comprising: a receptacle, said receptacle comprising a pump action device, said pump action device comprising a surface having an annular protrusion surrounding an aperture; anda disposable cartridge provided within the receptacle, said disposable cartridge comprising: a reservoir,a bladder disposed within said reservoir, said bladder containing an additive, andan inlet check valve, anda diaphragm disposed over said inlet check valve to define a dose chamber in fluid communication with said bladder; wherein: said diaphragm comprises an additive outlet check valve in fluid communication with said dose chamber,said additive outlet check valve including a pair of sealing surfaces, saidinlet check valve is an umbrella valve,said additive outlet check valve is a duckbill valve, andsaid disposable cartridge does not include any surfaces in its fluid pathdownstream of said pair of sealing surfaces; andwherein said disposable cartridge is disposed within said receptacle such that said disposable cartridge moves within said receptacle such that said annular protrusion depresses said diaphragm and causes said additive outlet check valve to open and said dosing chamber to reduce in volume, forcing additive through said additive outlet check valve. 13. An additive dispensing system for a refrigerator, comprising: a receptacle comprising a pump action device and a guide, wherein said pump action device comprising a surface having an annular protrusion surrounding an aperture, and wherein the guide receives and holds said disposable cartridge within a space such that said disposable cartridge may move within said receptacle; anda disposable cartridge movably mounted within the receptacle, said disposable cartridge comprising: a reservoir,a bladder disposed within said reservoir, said bladder containing an additive,an inlet check valve, anda diaphragm in cooperation with said inlet check valve to define a dose chamber in fluid communication with said bladder, said diaphragm comprising an additive outlet check valve in fluid communication with said dose chamber,wherein said additive outlet check valve includes a pair of sealing surfaces,wherein said disposable cartridge does not include any surfaces in its fluid path downstream of said pair of sealing surfaces;wherein said disposable cartridge moves along its longitudinal axis within said guide such that said annular protrusion depresses said diaphragm and causes said additive outlet check valve to open and said dosing chamber to reduce in volume, forcing additive through said additive outlet check valve and from said additive dispensing system. 14. The additive dispensing system according to claim 13, wherein said disposable cartridge slides within said receptacle.
