I claim: .[.1. A safety container closure assembly including, 
     
        and thereby remove the internal closure..]. .[.2.  The safety container closure assembly of claim 1 including means to limit the extent of insertion of said internal closure into said opening..]. .[.3. The safety container closure of claim 1 wherein said external cap engages a portion of said container..]. .[.4. The safety container closure of claims 1, 2 or 3 whereby said key is carried by a peripheral portion of said external 
     
     
        closure..]. 5. The safety container closure of claim 1 wherein said external closure cap is provided with a peripheral skirt, the lowermost part of said skirt carrying said key, the interior of said skirt carrying an annular bead which snaps over a complementary bead around an outer periphery of the container opening.Iadd., whereby the key carried by the external cap functions as a tab against which the thumb is pressed in a generally upward direction to remove the external cap from the container and functions additionally as a key for cooperation with the key recess of the internal closure to thereby permit the internal closure to be removed from its position within the opening of the container. .Iaddend. .[.6. The assembly of any of claims 1, 2 or 3 wherein said internal closure includes a central disc portion and wherein said key recess is an aperture therethrough..]. .[.7. The assembly of any of claims 1, 2, or 3 wherein said internal closure includes an integral, annular skirt whose outer peripheral surfaces frictionally fit the internal closure within said container opening..]. .Iadd. 8. A safety container closure assembly including, (a) a container having an opening,   (b) an internal closure in the form of a plug positioned within said opening, said closure having a key recess therein,   (c) an outer closure in the form of an external cap positioned over said opening,   (d) said external cap having a skirt integral therewith and depending from the top of said cap, the interior of said skirt carrying an annular bead which snaps over a complimentary bead on the outer periphery of container opening,   (e) a combination thumb abutment-key integral with and extending substantially horizontally outwardly from said skirt at the lower portion of the skirt, said thumb abutment-key functioning as a tab against which the thumb is pressed in a generally upwardly direction to remove the said external cap from the container and functioning additionally as a key for cooperation with the said key recess of said internal closure to thereby permit said internal closure to be removed from its position within the opening of said container. .Iaddend.
