Patent attributes
A closure assembly includes torque limit capabilities facilitating the attachment thereof to a medical connector with sufficient tightness to establish a flow stopping or sealing relation with the medical connector. A housing includes a stop member fixed on the interior thereof and rotatable there with into interruptive engagement with a movement restrictor connected to and movable with a closure cap which includes a flow restrictor. Application of a tightening force to the housing will cause rotation of the stop member into interruptive engagement with the movement restrictor and connected flow restrictor causing forced rotation of the flow restrictor onto attachment with the medical connector, while establishing a predetermined tightness. Over-tightening is prevented by disengagement of the stop member from will the movement restrictor or disconnection of the flow restrictor from the corresponding movement restrictor once the predetermined tightness has been established and upon a continuing tightening force being applied to the housing.
