Abstract
A child-resistant closure and container package having push tabs formed in the closure to prevent rotation relative to the container until the push tabs are deflected radially inwardly to disengage from lock members on the container to permit unthreading rotation of the closure relative to the container. Simultaneous squeezing of the push tabs and rotation of the closure permit removal of the closure from the container. Also, a tamper indicating feature is associated with the push tabs.
