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.

The method of claim 9, further comprising: providing the baffle ring spaced axially below the nozzle and positioned within the metering cup. 12. The method of claim 9, further comprising: providing at least one opening in the circumference of the baffle ring in communication with the passageway, anddirecting at least a portion of the controlled quantity of material from the metering cup to a location radially outward of and adjacent said baffle opening, through the baffle opening in a radially inward direction, and into the passageway. 13. The method of claim 9, further comprising: providing the baffle with an angled baffle plate extending radially outward from the metering cup. 14. The method of claim 13, further comprising: providing an outer surface of the inner reservoir positioned substantially parallel to the baffle plate, anddirecting at least a portion of the controlled quantity of material through a space between the outer surface of the inner reservoir and the baffle plate and into the passageway. 15. The method of claim 9, further comprising: providing the baffle ring disposed generally coaxially with the nozzle and with the metering cup. 16. A method of dispensing a measured quantity of granular material from a dispenser composed of a container assembly having a passageway in communication with an opening for the outflow of granular material, an inner reservoir containing granular material, the inner reservoir positioned within the container assembly and having an opening for the outflow of granular material, a metering cup coupled to the container assembly and positioned opposite the reservoir opening, the metering cup in communication with the reservoir opening for receiving a measured quantity of material from the reservoir and in communication with the passageway for discharging the measured quantity of material and a baffle comprising a generally annular baffle ring positioned within the metering cup, the baffle ring spaced axially from the reservoir opening and radially inward of the metering cup, comprising: positioning the container assembly in a first orientation to direct a measured quantity of material from the reservoir through the reservoir opening and into the metering cup;contacting the measured quantity of material received within the metering cup with the baffle ring; andpositioning the container assembly in a second orientation to deliver the measured quantity of material from the metering cup through the passageway and to direct the measured quantity of material through the passageway and out the assembly opening. 17.
