The dispenser dispenses premeasured quantities of a granular or powdered material when a lever on the dispenser housing is pressed inwardly. The quantity dispensed with each stroke of the lever can be adjusted easily by turning a dial on the outside of the housing. This adjusts the effective volume of a pair of telescoping tubes inside the dispenser, The dispenser is easily refilled merely by removing the top cap and pouring in the material to be dispensed.
