Machine and methods for dispensing nutritional supplements and multi-serving cartridge therefor
A granulated nutritional supplement dispensing machine extracts single-serving doses from a multi-serving supplements cartridge for delivery as a drinkable solution. A lead serving chamber is pierced so that its powered contents drain into a mixing cup together with a metered quantity of water from an integrated water tank. A vibrator unit assists drainage of the granulated materials from the lead serving chamber. The mixing cup is rotated at high speed to blend the water and supplements into a slurry. The supplements cartridge is indexed after (or before) use so that an unopened serving chamber is presented each time for extracting its supplements. This enables partially-used supplements cartridges to be used in the machine, as is conducive in multiple-user households. The supplements cartridge is configured with read-write data capability to indicate whether or not the contents of each serving chamber have been emptied.
1. A multi-serving cartridge assembly for granulated nutritional supplements, said cartridge assembly comprising:
a generally annular frame centered about a central axis, said frame comprising a generally flat annular member having an outer peripheral flange about its exterior and an interior hole centered about said central axis, a plurality of chamber openings disposed within said frame, sidewalls surrounding each said chamber opening and extending generally axially from said frame, said sidewalls for each said chamber opening being covered by a closed end to form a serving chamber behind the respective said chamber opening,
a volume of granulated nutritional supplement contained in each of said serving chambers,
a punctureable membrane directly affixed in surface-to-surface relationship to said frame and sealingly covering said serving chambers, said membrane configured to be forcefully ruptured in order to extract the volume of granulated nutritional supplement from said serving chambers, said punctureable membrane having an inner hole aligned with said interior hole of said frame, and
a spline cup directly affixed to said frame, said spline cup centered along said central axis and covering said interior hole in said frame, said spline cup including a plurality of female splines axially extending internal to said spline cup and accessible through said interior hole by the male splines of an output shaft of a dispensing machine, an outer surface of said spline cup forming a knob inset within said serving chambers, an annular clearance space in-between said knob and said servings chambers enabling said knob to be grasped with human fingers.
2. The assembly of claim 1 , further including a binary code indicia imprinted on said membrane.
3. The assembly of claim 2 , wherein said binary code indicia comprises a bar code disposed within an innermost annular region of said membrane adjacent said interior hole.
4. The assembly of claim 1 , wherein said punctureable membrane includes a plurality of marker zones spaced apart from said serving chambers, one said marker zone being associated with each said serving chamber.
5. The assembly of claim 4 , wherein said marker zones are disposed within an intermediate annular region of said membrane, said marker zones arranged in equal radial and circumferential increments about said central axis within said intermediate annular region.
6. The assembly of claim 5 , wherein each said marker zone is radially aligned with a respective one of said serving chambers.
7. The assembly of claim 6 , wherein said frame includes a marker cavity located behind each said marker zone.
8. The assembly of claim 1 , wherein said plurality of serving chambers comprises between twenty-eight and thirty-one.
9. The assembly of claim 1 , wherein each said chamber opening has a radially widening wedge shape being narrowest adjacent said interior hole and widest adjacent said outer peripheral flange.
