Patent ID: 7111746

Claim:
A shellable closure for a container includes an inner cap and an outer cap designed to be nested for a child resistant mode and purposefully shellable for use in a non-child resistant mode; the inner cap and the outer cap each have a row of angular abutments; the inner cap is coaxially positioned and nested within the outer cap such that the row of angular abutments of the inner cap engage the 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; said outer cap has at least two tabs and said inner cap has a groove and at least one channel, said tabs being spaced about the outer cap and fitted in said groove; said tabs shaped to hold said outer cap in nesting relation to said inner cap when said tabs are fitted in said groove; said channel being shaped to allow one of said tabs to pass through said channel whereby when one of said tabs and said channel are aligned, said outer cap can be easily removed from its nesting relationship relative to said inner cap.
