Abstract
A child-resistant closure and dispensing container package in which the measuring cup has a second, exterior annular wall forming threads engageable with threads on the neck of a container and child-resistant lock means at a lower portion of the wall engageable with complementary lock means on the container in a locked position to prevent unthreading of the closure from the container until the annular wall is deflected to move the complementary lock means out of engagement with each other to permit rotation of the closure in an unthreading direction. Also a seal is provided to prevent leakage during unthreading movement of the closure between fully closed and a locked position of the closure.
