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.

Child-resistant package

A child resistant package which includes a container having an open end and multiple threads on the external surface of the container adjacent the upper end. A closure having a base wall and a peripheral skirt has an inner surface formed with single or multiple threads corresponding in number to the multiple threads on the container for engaging the threads on the container. A deflectable release element is formed integrally on the container. The release element includes an integral axially deflectable lug extending upwardly toward the open end of the container. The closure has at least one locking lug on the skirt of the closure, the number of locking lugs preferably corresponding to the number of threads on the container and closure. The deflectable lug on the deflectable release element normally extends upwardly for engagement with the locking lug such that when the release element is pressed radially inwardly, the lug is disengaged from engagement with a locking lug and the closure can be removed by unthreading the closure from the container. When the closure is reapplied minimal torque is required due to the axial deflection of the lug and one of the stops on the closure moves past the lug. In a preferred form of the child resistant package, the deflectable release element and container include interengaging stops to limit the deflection on the release element.
