  • Patent number: 10759594
    Abstract: 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.

  • Patent number: 7988016
    Abstract: A pill dispensing cap that secures to a conventional pill container. The pill dispensing cap has a lower cap, a pill discharge port, and a spring loaded rotatable and slidable upper cap. Pills are dispensed one at a time, and the remaining pills are isolated from external contamination. A child resistant lock prevents small children and/or mentally handicapped individuals from easily accessing medicine inside the container. The child resistant lock uses a vertically slidable upper cap that is slidably and rotatably attached to the lower cap. A child safety lock uses a key in the upper cap that must be aligned with a slot in the lower cap to allow a pill to be dispensed. When the key and slot are aligned, the upper cap is vertically compressed against the lower cap. As the upper cap moves toward the base cap, a gravity fed pill discharge port is exposed which releases a single pill.
