wherein the first piece adapter ring locking member includes locking tabs for securing the first piece adapter ring locking member to the container rim, and wherein the locking tabs include a serrated surface; and
a round upper second piece lid portion configured to mate with the lower first piece adapter ring locking member,
wherein, when the first piece adapter ring locking member is securely affixed to the container rim and the second piece lid portion mates with the first piece adapter ring locking member, the lid portion is thereby child resistantly secured to the first piece adapter ring locking member.
2. The two-piece child resistant container lid of claim 1 , wherein the first piece adapter ring locking member includes a first rotational alignment indicator section.
3. The two-piece child resistant container lid of claim 2 , wherein:

4. The two-piece child resistant container lid of claim 2 , wherein:
the second piece lid portion includes a second rotational alignment indicator section, and
the locking trough includes a relieved area directly beneath the first rotational alignment indicator section,
and wherein, when the first and second rotational alignment indicator sections are lined up directly and in alignment, the second piece lid portion can readily be removed from the round lower first piece adapter ring locking member.
