ABSTRACT:
A container for holding liquid in its interior includes an aperture which provides access to the interior of the container. A valve has an open position and a closed position, is mounted in the aperture and mates with an actuator when the container is inserted into a print mechanism. The actuator causes the valve to transition from the closed position to an open position and vice-versa. A seal member is rotatably mounted in the aperture and includes a pathway for receiving the actuator. The pathway is normally positioned nonaligned with the aperture so as to render the valve non-accessable from outside the container. A control mechanism is coupled to the seal member and rotatably moves the seal member to reposition the pathway into alignment with the aperture so as to be in position to receive the actuator. The control mechanism is actuated when the container is inserted into the print mechanism.
