Apparatus for dispensing a substance

摘要

A container filling apparatus includes at least one source container that contains a substance and a reading mechanism capable of reading data from a data indicator on a receiving container wherein the data indicator identifies data about the receiving container. The apparatus also includes a controller that is connected to the reading mechanism. The controller is programmed to determine when a dispensing condition is satisfied. The apparatus also has a dispenser for discharging the substance into the receiving container in response to a signal from the controller. The dispensing condition can be a match between data from the data indicator and the data stored for access by the controller. The source container can also have a data indicator. The dispensing condition is then satisfied when the data from the source container data indicator matches the data from the receiving container data indicator.
