Cam lid for drinking vessel

A lid assembly for a drinking vessel, comprising:

• a lid main body having a lid portion with a recess defined at least in part by a drinking lip and first and second lid sidewalls projecting upwardly from first and second lid upper surfaces, respectively, the first and second lid upper surfaces extending along and adjacent to opposite sides of a drinking aperture located within the recess;
• a sealing member having a sealing portion sized and shaped to selectively seal the drinking aperture, the sealing member being pivotally attached to the lid main body and rotatably movable between a sealed position with the sealing portion sealing the drinking aperture and an unsealed position with the sealing portion unsealing the drinking aperture;
• an actuator having a manually rotatable actuation member rotatably movable between first and second rotational positions, and first and second laterally spaced apart cams attached to the actuation member for rotation in response to rotation of the actuation member between the first and second rotational positions, the first cam being positioned to engage the first lid upper surface for rotation and the second cam being positioned to engage the second lid upper surface for rotation of the first and second cams about a common center rotational axis of the first and second cams;
• and
• a connector member extending between and connected to the sealing member and the first and second cams, the connector member being rotatably coupled to the first and second cams for rotation about a fixed rotational axis relative to the first and second cams, the fixed rotational axis being offset from the common center rotational axis of the first and second cams, wherein as the actuation member is rotated from the second rotational position to the first rotational position, the first and second cams rotate about the common center rotational axis of the first and second cams when in engagement with the first and second lid upper surfaces to move the connector member upward and rotate the sealing member into the sealed position, and wherein as the actuation member is rotated from the first rotational position to the second rotational position, the first and second cams rotates about the common center rotational axis of the first and second cams when in engagement with the first and second lid upper surfaces to move the connector member downward and rotate the sealing member into the unsealed position.

• an actuator having a manually rotatable actuation member rotatably movable between first and second rotational positions, and a cam attached to the actuation member for rotation in response to rotation of the actuation member between the first and second rotational positions, the cam having a cam face positioned to engage the lid upper surface for rotation about a first rotational axis of the cam without engagement with the lid sidewall;
• and
• a connector member extending between and connected to the sealing member and the cam, the connector member being rotatably coupled to the cam for rotation about a fixed second rotational axis relative to the cam, the fixed second rotational axis being offset from the first rotational axis of the cam, wherein as the actuation member is rotated from the second rotational position to the first rotational position, the cam rotates about the first rotational axis of the cam when in engagement with the lid upper surface to move the connector member upward and rotate the sealing member into the sealed position, and wherein as the actuation member is rotated from the first rotational position to the second rotational position, the cam rotates about the first rotational axis of the cam when in engagement with the lid upper surface to move the connector member downward and rotate the sealing member into the unsealed position.
