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.

[ We claim:] [1.] A child resistant package comprisinga plastic container having an open end,thread means on the external surface of the container adjacent the open end for securing a closure,a plastic closure having a peripheral skirt,said skirt having an inner surface formed with thread means for engaging the thread means on the container,a deflectable release element formed integrally on the exterior surface of the container and mounted on said container for radial and axial movement relative to said container,a lug mounted on said release element and extending upwardly toward the open end of the container, andstop means between said deflectable release element and said container exterior surface, said stop means being spaced from each other when said deflectable release element is undeflected toward the container exterior surface and being brought into abutment when said deflectable release element is deflected toward said container exterior surface for limiting deflection of said release element toward said container exterior surface and away from said open end.
