1. A topical applicator comprising:
a barrel with a first end and a second end;
an elevator slidably and sealably disposed within said barrel, the elevator attached to a threaded rod extending from the elevator toward the first end of said barrel, the barrel and elevator defining a reservoir;
an access port disposed on second end of said barrel through which flowable compounds may be added to or expelled from said reservoir;
a threaded nut with integral threads to engage threads of said threaded rod, said threaded nut including an integral knob, said nut and knob radially and axially constrained at first end of said barrel;
an actuating means disposed on or in relation to said barrel, wherein operating said actuating means toggles said threaded nut from disengaged to engaged with said threaded rod;
wherein said flowable compound can be added to said reservoir, causing said elevator to translate in a first axial direction of said barrel, when the actuating means has not engaged said threaded nut with said threaded rod, and,
wherein rotating said knob in a first direction translates said elevator in a second axial direction of said barrel when actuating means has engaged said threaded nut with said threaded rod to expel said flowable compounds through said access port.
