SAFETY CLOSURE AND CONTAINER PACKAGE ABSTRACT OF THE DISCLOSURE A safety closure and container package including an internally threaded closure cap and a container having a threaded neck. A retention flange is located on the container neck below the threads, having a gradually sloping upper surface and an abrupt, inwardly directed lower surface extending downwardly toward the neck at 44 ° - 90° . A coacting inwardly projecting retention bead on the cap completes this child-resistant feature requiring considerably more force for removal of the closure than application. The safety package can also include a second container flange and cap bead located between the retention flange and bead and the threads to provide a non-backoff feature. The non-backoff flange has a gradually sloping upper surface and a gradually sloping inwardly directed surface extending downwardly toward the container neck at 15° - 25° . The coacting inwardly projecting non-backoff bead on the cap will retain the cap in sealing contact with the container neck even during initial unthreading to provide a second safety feature. These safety features can be applied to a standard threaded package or to a dispensing package in which the closure includes a threaded cap having a dispensing orifice in its top and a lid hinged to the cap for closing of the orifice.
