Patent ID: 7124904

Claim:
A reversible child resistant closure for use with a container, the closure having a child resistant mode when applied to the container in a first child resistant position and having a non-child resistant mode when applied to the container in a second non-child resistant position, the closure comprising: an outer cap comprising a first circumferential side wall extending from a top edge to a bottom edge, wherein the first circumferential side wall has a first inner surface with a non-child resistant engaging means for rotatable engagement with the engaging means of the container and a first child resistant engaging means axially offset from the non-child resistant engaging means comprising a series of angular abutments extending about the first inner surface; an inner cap comprising a second circumferential side wall extending axially from an upper surface, wherein the second circumferential side wall has a second inner surface and an outer surface, the second inner surface provided with a second child resistant engaging means for rotatable engagement with the engaging means of the container and the outer surface provided with a third child resistant engaging means having a plurality of angular abutment surfaces complementary to the series of angular abutments on the outer cap; wherein the inner cap is coaxially positioned and nested within the outer cap and axially movable between the first child resistant engaging means of the outer cap and the bottom edge of the outer cap such that the plurality of angular abutment surfaces of the inner cap engage the series of angular abutments of the outer cap upon rotation of the outer cap to rotate the inner cap in a closing direction and in the absence of an axial force, cam over and past the series of angular abutments of the outer cap upon rotation of the outer cap member in an opening direction to prevent rotation of the inner cap; and wherein the upper surface of the inner cap comprises an inner surface on which is marked a warning.
