an outer shell having an outer top panel, an outer cylindrical sidewall extending downward from the outer top panel, and a engagement groove disposed on an inner facing of the outer cylindrical sidewall;
an inner shell nested within the outer shell and movable in an axial direction relative to the outer shell, said inner shell having an inner top panel, an inner skirt extending downward from the inner top panel, a radially protruding engagement feature disposed on an inner facing of the inner cylindrical sidewall and received and restrained within the engagement groove;
wherein selectively interlocking child resistant features are formed on each of the outer shell and the inner shell along an interface therebetween;
wherein downward movement of the outer shell urges the protruding engagement feature against an upper facing of the engagement groove so as to provide enhanced hoop strength to the closure in a radial direction; and
