A child resistant package which includes a container having an open end and single or multiple threads on the external surface of the container adjacent the upper end. A closure having a peripheral skirt has an inner surface formed with single or multipl e threads corresponding in number to the 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 th e 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 deflectable lug and one of the locking lugs on the closure moves past the lu g. In a preferred form of the child resistant package, the deflectable release element and containe r include interengaging stops to limit the deflection on the release element.
