Abstract:
1. A device for quantitatively measuring different and indeterminate amounts of a material dispensed, said device comprising: a reservoir for holding a material therein; a dispensing orifice for dispensing material contained in said reservoir therefrom; a dispenser for dispensing differing amounts and indeterminate quantities of the material from the reservoir through said orifice, said dispenser having an actuator movable relative to said reservoir; a member which is stationary relative to said dispenser; a Hall effect sensor disposed on one of said actuator and said stationary member; a magnet disposed on the other of said actuator and said stationary member, whereby relative movement between said magnet and said Hall effect sensor from a first position to a second position produces a quantitative signal in response to said movement, said signal being correlatable to an indeterminate quantity of material dispensed from said reservoir.
