         2 . The child resistant closure assembly of  claim 1 , wherein a dropper is positioned in the outer housing and the inner housing. 
     
     
         3 . The child resistant closure assembly of  claim 2 , wherein the inner housing includes an inner dropper receiving passageway engageable with an outer wall of a dropper. 
     
     
         4 . The child resistant closure assembly of  claim 1 , wherein each of the plurality of sloped cams includes a circular engagement wall positioned on a leading edge of the sloped cams. 
     
     
         5 . The child resistant closure assembly of  claim 3 , wherein the plurality of circular lugs are concentrically offset from the inner dropper receiving passageway of the inner housing. 
     
     
         6 . The child resistant closure assembly of  claim 5 , wherein the plurality of circular lugs are positioned adjacent to an inner housing dropper mounting area. 
     
     
         7 . The child resistant closure assembly of  claim 3 , wherein the inner housing includes a molded inner dropper receiver coupling along the upper surface. 
     
     
         8 . The child resistant closure assembly of  claim 6 , wherein the plurality of circular lugs engage with each of the sloped cams and the plurality of circular lugs abut a plurality of circular engagement walls to rotate the inner housing in a clockwise locking direction when the outer housing is in a lower position. 
     
     
         9 . The child resistant closure assembly of  claim 6 , wherein the plurality of circular lugs disengage each of the sloped cams, and engage the upper surface of the inner housing, above the sloped cams, to couple the inner housing to the outer housing at an upper position and to rotate the inner housing and the outer housing in a counterclockwise unlocking direction when the outer housing is in an intermediate position. 
     
     
         10 . The child resistant closure assembly of  claim 6 , wherein the plurality of circular lugs disengage the sloped cams and the upper surface of the inner housing, and the outer housing is freely rotatable in a clockwise and a counterclockwise direction when the outer housing is in an upper position. 
     
     
         11 . The child resistant closure assembly of  claim 3 , wherein the outer housing includes an outer dropper receiving passageway having a larger diameter than a diameter of the inner dropper receiving passageway. 
     
     
         12 . The child resistant closure assembly of  claim 11 , wherein the outer housing includes a retaining flange around a base thereof that is engageable with the inner housing. 
     
     
         13 . The child resistant closure assembly of  claim 3 , wherein in a dropper assembled state the dropper is received in the inner dropper receiving passageway, in a molded inner dropper receiver coupling, and in an outer dropper receiving passageway. 
     
     
         14 . The child resistant closure assembly of  claim 1 , wherein the inner housing is a thermoset material. 
     
     
         15 . The child resistant closure assembly of  claim 1 , wherein the outer housing is a thermoplastic material. 
     
     
         16 . The child resistant closure assembly of  claim 1 , wherein the sloped cams have a width corresponding with the outer housing when the plurality of circular lugs are engaged. 
     
     
         17 . The child resistant closure assembly of  claim 16 , wherein the inner housing has around a base a mating flange for coupling with a retaining flange. 
     
     
         18 . The child resistant closure assembly of  claim 1 , wherein the plurality of circular lugs are equally spaced around a lower face of the outer housing. 
     
     
         19 . The child resistant closure assembly of  claim 1 , wherein the inner housing, relative to a retaining flange, vertically decouples from the retaining flange around a base of the outer housing when the plurality of circular lugs are partially engaged with the sloped cams. 
     
     
         20 . The child resistant closure assembly of  claim 19 , wherein a separation is formed between the inner housing and the retaining flange when the inner housing vertically decouples from the retaining flange. 
     
     
         21 . The child resistant closure assembly of  claim 2 , wherein the dropper includes a bulb. 
     
     
         22 . A child resistant closure assembly comprising:
 an inner housing having an upper surface and a plurality of centrally positioned sloped cams extending concentrically into the upper surface in a curvilinear direction;   an outer housing corresponding to the inner housing and having a plurality of circular lugs spaced apart and extending downward from a planar surface to correspond with the sloped cams, the plurality of circular lugs are centrally positioned and curvilinear along the outer housing on the upper surface; and   a dropper positioned through the outer housing and the inner housing.
