Abstract
Abstract A safety container including an externally threaded tubular neck having an opening extending through the neck to the container wherein the neck extends outwardly from the container body to threadably receive a closure, the area of the top of the tubular neck being either perpendicular or tapered downwardly from the tubular neck in which at least the area adjacent the neck is provided with means cooperating with a locking means carried by the closure to prevent the normal rotation of the closure in the opposite direction to the downward pitch of the thread carried by the neck, the locking means being manually operatable to disengage the locking means carried by the closure to allow the closure to be rotated to remove the closure from the container neck.
