An child-resistant closure for bottles and similar containers is provided. This child-resistant closure is provided with an inner cap which has a plurality of triangular saw tooth projections located on its outer surface and an outer cap which fits over and rotates relative to the inner cap and is provided with knurlings located on its inner surface. The knurlings of the outer cap are complementary to and angled the same way as the saw tooth projections of the inner cap so that when the outer cap is rotated in the opening direction, the knurlings will move freely or ratchet over the saw tooth projections. However, when axial force is applied to the outer cap toward the inner cap, the knurlings cam against the saw toothed projections causing the caps to rotate in unison and disengage from the container. Additionally, this child-resistant closure utilizes a guide on the inner surface of the outer cap to keep the inner cap in alignment with the outer cap.
