A two piece safety or child resistant closure for a container in which one piece is a cylindrical cap which is attached to the container by threads or by a flange to snap onto the container. The cap has a dispensing orifice which may be located on the end of a spout through which the contents of the container are dispensed. The second piece of the closure is a cover which is rotatably connected to the cap. When the cover is rotated to its closed position, the dispensing orifice is covered and sealed and the cover is locked against rotation. A rocker arm occupying a portion of the cover is connected to the cover by a torsion hinge and contains the locking mechanism. In order to put the closure into its dispensing position, the rocker arm must be depressed at the same time that the cover is rotated. Rotation of the cover to the dispensing position uncovers the dispensing orifice. When the cover is rotated back to its closed or sealed position, the rocker arm drops back into its original position engaging the lock.
