1. A portable liquid dispensing device comprising: (8) (3)

a liquid cartridge containing a prefilled desired liquid supported within the dispensing device;

a dispensing mechanism positioned for engagement with the liquid cartridge for dispensing a desired amount of liquid from the liquid cartridge to an outlet exiting the device; and

an actuator button for actuating the dispensing mechanism for dispensing the desired amount of liquid through the outlet of the dispensing device.

2. The portable liquid dispensing device of claim 1 wherein the dispensing mechanism further comprises a central shaft with a central axis aligned with a central axis of the portable liquid dispensing device, a first end of the central shaft is engaged with the actuator button, a second end of the central shaft is positioned adjacent the outlet, and a plunger assembly supported on the central shaft intermediate the first and second ends for substantially sealed engagement with an internal surface of the liquid cartridge and central shaft to move the plunger assembly and liquid toward the outlet upon actuation of the actuator button, and slidably move or retract the central shaft through the plunger assembly upon deactivation of the actuator button. (4) (0)

3. The portable liquid dispensing device of claim 2 wherein the dispensing mechanism further includes a top housing for supporting engagement with the actuator button on one end, an inner wall of the top housing engages an outer wall of a lead screw slidably supported on the central shaft, and a portion of the inner wall of the top housing includes a flat stop surface to restrict movement of the lead screw with respect to the top housing. (2) (0)

4. The portable liquid dispensing device of claim 3 wherein the dispensing mechanism further includes a lower housing having male threads formed on a narrow inner wall portion of the lower housing for mating engagement with the female threads formed on the outer wall of the lead screw, and the inner wall of the top housing and inner wall of the lower housing are aligned to capture the lead screw within the top and lower housings. (1) (0)

19. The dispensing device of claim 3, wherein the device includes software, hardware and firmware for storage of the desired amounts or doses of liquid to be dispensed from the liquid cartridge, the sensed amounts of liquid material dispensed from the outlet, and Bluetooth enabled technology for interfacing with a cellular phone or computer to communicate with the device for activation of the dispensing mechanism, for modification of the desired amounts of any doses to be dispensed, and the sensed amounts of liquid material dispensed. (0)

6. The portable liquid dispensing device of claim 2, wherein the plunger assembly supported on the central shaft comprises a plunger driver having a central opening engaged with the central shaft, a lower support shelf supporting a seal member for substantially sealed and slidable engagement with the central shaft and the internal surface of the liquid cartridge, and a top surface having rigid clips secured to the top surface to engage the central shaft and the internal surface of the liquid cartridge to move the central shaft and plunger assembly toward the outlet during actuation of the actuator button and permit retraction of the central shaft through the plunger assembly following deactivation of the actuator button. (0)

16. The portable liquid dispensing device of claim 2, wherein the liquid cartridge is refillable and includes a removable end cap for engagement with an end of the liquid cartridge adjacent the second end of the central shaft and formed with the outlet for fluid exiting the device. (0)

17. The portable liquid dispensing device of claim 2, wherein the central shaft has a first diameter portion engaged with the actuator button, lead screw and plunger assembly, and a second and narrower diameter portion sized for sliding engagement with an internal surface of the outlet, and a sealing tip is provided on the second end of the second and narrower diameter portion of the central shaft to engage and seal the outlet during retraction of the central shaft. (0)

9. The portable liquid dispensing device of claim 1, wherein the desired amount of liquid to be dispensed is adjustable between approximately 0.1 ml and 1.0 ml. (0)

10. The portable liquid dispensing device of claim 1, wherein the liquid cartridge contains a prefilled desired liquid amount of at least approximately 10.0 ml. (0)

11. The portable liquid dispensing device of claim 1 wherein the liquid cartridge contains a prefilled desired liquid amount of less than 10.0 ml. (0)

12. The portable liquid dispensing device of claim 1, wherein an external case houses the portable liquid dispensing device and includes a viewing window for visually determining the amount of liquid remaining within the liquid cartridge. (0)

13. The portable liquid dispensing device of claim 1, wherein an external case housing the portable liquid dispensing device is an interconnected two-piece housing having an opening in a top piece for slidably accessing the actuator button therethrough, and the top piece of the external case is engaged with the top housing, and the top piece of the external case is rotatable with respect to the interconnected lower piece, for similarly rotating the top housing with respect to the lower housing to the desired volumetric position where the volumetric indicia on the top and lower pieces are aligned for selecting the desired volume of liquid to be dispensed. (0)

14. The portable liquid dispensing device of claim 1, wherein the liquid cartridge is disposable. (0)

15. The portable liquid dispensing device of claim 1, wherein the portable liquid dispensing device is disposable. (0)

18. A portable electronic liquid dispensing device comprising, (0) (5)

a power supply supported within the dispensing device;

a removable liquid cartridge containing a pre-filled desired liquid material supported within the dispensing device;

a dispensing mechanism positioned for engagement with the removable liquid cartridge for dispensing a desired amount of liquid material from the liquid cartridge to an outlet exiting the device;

an actuator button for actuating the dispensing mechanism for dispensing the desired amount of liquid material through the outlet of the dispensing device

a sensor positioned within the dispensing device for sensing and storing the amount of liquid material dispensed from the outlet.
