Abstract
A method is provided for dispensing a controlled quantity of a granular material. The method employs a dispenser including a reservoir that retains granular material. The reservoir is supported in the dispenser with a passageway defined between opposing ends. The dispenser is first positioned in a loading orientation for the outflow of material from the reservoir through a nozzle to a metering cup. A baffle positioned proximate the opening of the metering cup stabilizes the controlled volume directed into the cup from the reservoir. Once the metering cup is filled, the dispenser is inverted. Then, the volume of material is directed from the cup through the passageway and out of an opening adjacent a diffuser, through which the material is spread.
