A dispenser for particulate material, includes a vessel for storing the particulate material, a dispensing head attached to or formed integrally with the vessel, the dispensing head having an port communicating with the vessel, a trigger movable with respect to the head and comprising a plurality of metering compartments that can be brought into alignment with the port upon depression of the trigger. The trigger has a number of steps formed thereon. A user-adjustable stopper is mounted upon the dispensing head and is configured to interact with the steps to selectively limit depression of the trigger to thereby align a selected one or more of said metering compartments with the port.
