ABSTRACT:
An improved safety closure cap with an integral sealing torque control means is disclosed for use on medicine or other packages where it is desirable that children cannot open the package. The cap has an inner shell with container engaging thread means and an outer shell rotatably attached to the inner shell. Ratchet means including means for controlling the maximum cap application torque locks the shells together as they are turned onto a container. The ratchet means is inoperative as the cap is turned off permitting the outer shell to freely rotate on the inner shell. A second shell connecting means is provided for removal in the form of a pressure operated interlock which is activated by an adult's gripping certain portions of the shells to turn them off as a unit.
