Abstract
A dispensing device to meter the discharge of a predetermined amount of a given material, particularly a food product having a thixotropic consistency, wherein a tubular chamber is defined by an elongated housing having a discharge nozzle and a floating piston head disposed in the chamber, the piston head being moved by a threaded shaft which is controlled by a spring-loaded tooth member that allows the shaft to be selectively rotated, causing the piston head to be moved to a predetermined distance, thereby discharging the required amount of material.
