1. A dispensing apparatus for fluids comprising:
a first end;
a second end;
an outer sleeve having an open first end, and a plunger slidably interconnected within the outer sleeve;
a cartridge comprising a chamber adapted for containing fluid therein, and a dispensing tip at a first end of the cartridge;
the dispensing tip comprising a pathway extending therethrough between a first end of the dispensing tip and a second end of the dispensing tip;
the chamber further comprises a plunger tip slidably interconnected within a bore of the chamber, the plunger tip configured to dispense fluid held within the chamber when the plunger tip is advanced toward the dispensing tip;
the cartridge is configured to be releasably interconnected with the outer sleeve wherein a second end of the cartridge, is configured to be axially slidably inserted within the open first end of the outer sleeve, and wherein the first end of the cartridge is configured to interlock with the first end of the outer sleeve;
the plunger further comprises a first end configured to interconnect with the plunger tip when the cartridge is interconnected with the outer sleeve;
an intermediate sleeve slidably connected within the outer sleeve, wherein the intermediate sleeve comprises a female threaded feature; and
the plunger comprises a lead screw with threads between the first end of the plunger and the second end of the plunger, wherein the threads are adapted to intermesh with the female threaded feature, wherein:
when the cartridge is interconnected with the outer sleeve, the first end of the plunger is interconnected with the plunger tip, and when a second end of the plunger is depressed toward the first end of the outer sleeve, the plunger tip advances toward the dispensing tip, thereby dispensing the fluid from the chamber, through the pathway, and out of the first end of the dispensing tip, and
axial rotation of the lead screw in a first direction in relation to the female threaded feature results in longitudinal extension of the assembled plunger and intermediate sleeve.
