The child-proof closure cap according to claim 1, further comprising a flange disposed at an end of the second skirt along a circumference of the second skirt, said flange projecting inward from the second inner surface of the second skirt, wherein the flange contacts the outer surface of the first skirt. 8. The child-proof closure cap according to claim 7, wherein the outer surface of the first skirt has a circumferential lip positioned under the notches; and wherein a portion of the flange is adapted to engage the circumferential lip when the outer cap is tilted, the engagement between the portion of the flange and the circumferential lip limiting a degree of tilt. 9. The child-proof closure cap according to claim 7, further comprising a tamper ring frangibly attached to an end of the first skirt by at least one fastener, said tamper ring adapted to be secured around an opening of the container to indicate tampering of the container. 10. The child-proof closure cap according to claim 9, wherein a portion of the flange is adapted to engage the tamper ring when the outer cap is tilted, the engagement between the portion and the tamper ring being adapted to release the tamper ring from the first skirt. 11. The child-proof closure cap according to claim 1, wherein each of the upwardly directed openings of the inner cap is formed in the outer surface of the first skirt and displaced below the first top panel so as to be spaced from the outer edge of the first top panel. 12. The child-proof closure cap according to claim 1, wherein, when no tilting force is applied to the outer cap, the first top panel is substantially parallel to the second top panel, the outer cap rotates about the inner cap without engagement between the teeth and the notches. 13. The child-proof closure cap according to claim 1, further comprising a plurality of protrusions disposed on an outer surface of the second skirt, said protrusions being adapted to provide a grip of the outer cap. 14. A child-proof closure cap for covering and sealing a container having an open neck with exterior threads, the child-proof closure cap comprising: an inner cap comprising: a first top panel; and,a first skirt extending downward from a peripheral edge of the first top panel, the first skirt having: an annular series of notches formed within an outer surface surrounding the first top panel and spaced from the peripheral edge; and,a first inner surface with interior threads for screwing the inner cap onto the corresponding exterior threads on the open neck of the container;an outer cap covering the inner cap and being tiltable and rotatable with respect to the inner cap, the outer cap comprising: a second top panel; and,a second skirt extending downward from the second top panel, the second skirt having: an annular series of teeth projecting radially inward from a second inner surface and proximate to the second top panel; and,a circumferential flange disposed at a distal edge and projecting inward from the second inner surface, wherein the circumferential flange engages the outer surface of the first skirt;an annular peripheral edge separating the annular series of teeth of the second skirt from the second top panel; and,wherein, when the outer cap is tilted with respect to the inner cap, the annular series of teeth at least partially engage the annular series of notches on the outer surface of the first skirt for turning the inner cap in a direction to release the inner cap from the container. 15. The child-proof closure cap according to claim 14, wherein the closure cap further comprises a plurality of fingers disposed around a circumference of the closure cap and extending substantially downward, the fingers being adapted to engage a protrusion on the container. 16. The child-proof closure cap according to claim 15, wherein the outer surface of the first skirt has a lip positioned under the annular series of notches and extending around the first skirt; wherein, when the outer cap is tilted, a first portion of the flange is adapted to engage the lip and at least one of said fingers is deflected, the engagement between the first portion and the lip limiting a degree of tilt, and the deflection disengaging at least one finger of said fingers from the protrusion on the container. 17.
