Abstract

A child resistant package comprising a container and closure. The container has a side wall, a bottom wall and an open end. The closure includes an outer member and an inner member, the inner member having a portion thereof extending through an opening in the outer member such that axial pressure may be applied through this portion to move the inner member relative to the outer member in an axial direction. A liner insert sealingly engages the upper end of the container. The inner member and the liner have interengaging portions such that when the closure is removed from the container, the liner insert is also removed. A portion of the liner defines a spring between the liner and the inner member to yieldingly urging the inner member axially outwardly toward the outer member. The container has radially resilient portions on the upper end of the side wall, and the outer member includes a peripheral skirt having a rib adapted to engage the radial resilient portions on the container.
