DROP DISPENSING DEVICE Abstract of the Disclosure A fluid drop dispenser is fabricated from an injection moldable plastic and includes inner and outer components each having an end wall and an axially extending cylindrical wall that define a respective counterbore for each component. The inner component is assembled to the outer component with the respective outer and inner axially extending walls defining an annular fluid receiving chamber therebetween. A nozzle is provided in the outer wall through which drops are ejected on demand. A piezoelectric actuator disc is mounted within the inner component with its periphery bonded to the cylindrical wall of the inner component. When the actuator disc is electrically excited, it undergoes a radially outward expansion to cause a predetermined quantity of fluid to be ejected from the annular chamber through the nozzle.
