AbstractA child-resistant, elderly-accessible safety container designed for storage of potentially hazardous materials. The closure includes three major components: a rotatable member secured coaxially around the neck of the container and having at least one biasing member disposed along its upper surface, at least one resilient abutment member, extending outward from the neck and terminating in a tip end, and is capable of being distended or compressed by the biasing member, and a closure member having at least one closure member stop disposed along its inner surface. Turning the rotatable member in a predetermined direction causes the biasing member to contact and compress the abutment member tangentially in relation to the outer surface of the neck. Such compression interrupts contact of the tip end of the abutment member with the closure member stop allowing the closure member to be rotated in the opposite direction and removed from the container. Alternatively, turning the rotatable member in another predetermined direction causes the biasing member to contact and distend the abutment member tangentially in relation to the outer surface of the neck. Such distension reinforces contact of the tip end of the abutment member with the closure member stop and prevents the closure member from being rotated in the opposite direction and removed from the container.
