A container closure locking assembly (40) includes a plastic container (42) having a body portion (54) for holding the contents, a lower closed end (56) for supporting the container (42), and an upper dispensing end (58). The upper dispensing end (58) includes a neck (60) and a round dispensing spout (64) having a central axis (A). The dispensing spout (64) extends upwardly from the neck (60) and further includes an external closure thread (68), a retaining flange (70), and a rotational positioning formation (72). A plastic lock ring (44) molded separately from the container (42) extends around and is supported by the neck (60) of the upper dispensing end (58) of the container (42) below the external closure threads (68) of the dispensing spout (64). The lock ring (44) includes retainers (82 and 84) to secure the lock ring (44) to the container (42) and at least one external lock (98) having a lock surface (100) and an unlocking actuator (102) for moving the lock surface (100) radially inward with manual movement. The lock ring (44) also includes a rotational positioning formation (96) to rotatively position the lock ring (44) about the central axis (A) of the dispensing spout (64). A closure (46) having an internal thread (110) is threaded onto the external thread (68) of the dispensing spout (64) of the container (42) to secure the closure (46) and close the container (42). The closure (46) has at least one internal lock (112) designed to engage the outer curved ramp surface (100) of the external lock (98) of the lock ring (44) to prevent unthreading rotation of the closure (46) from the dispensing spout (64). The lock surface (116) of the internal lock (112) of the closure (46) may be disengaged from the lock surface (100) of the external lock (98) of the lock ring (44) by inward manual movement of unlocking actuators (102).
