A shellable, positively lockable, child resistant closure and container includes a pair of nested inner and outer caps designed to be purposefully shellable for use in its non-child resistant mode. The inner cap is coaxially positioned and nested within the outer cap such that a row of angular abutments of the inner cap engage a row of angular abutments of the outer cap upon rotation of the outer cap in a closing direction, and upon rotation of the outer cap in an opening direction, without a concomitant axial force, the respective angular abutments cam over and past each other to prevent rotation of the inner cap. Additionally, the inner cap contains a positive locking device for engagement with a complementary locking device on the neck of the container.
