ABSTRACT:
A child resistant package includes a container having a finish with at least one external thread and at least one pocket in an undersurface of the thread. A closure for receipt on the finish of the container has a base wall, a skirt with an axis, at least one internal thread having at least one lug for receipt in the pocket of the container finish, and a spring disposed between the base wall and the container finish external thread. The spring yieldably biases the closure away from the finish and urges the lug into the pocket. The spring is a progressive spring that includes at least two spring rings preferably extending from the base wall at an angle to the axis of the skirt. The spring rings are radially spaced from each other and a first spring ring has a greater axial dimension or length than a second spring ring, with the first spring ring axially overlying the second spring ring.
