Abstract
A dispenser is provided for delivering a controlled quantity of a granular material. The dispenser includes a reservoir that retains granular material. The reservoir is supported in the dispenser with a passageway defined between opposing ends. A nozzle is provided for the outflow of material from the reservoir to a metering cup. A control plug is provided within the metering cup to adjust the controlled volume to be received within the cup from the reservoir. Once the metering cup is filled, the dispenser is inverted and the volume of material is directed from the cup, through the passageway and out of an opening adjacent a diffuser. The control plug is removable from the cup to vary the charge of material to be dispensed.
