Cam lid for drinking vessel

A lid assembly for a drinking vessel, comprising:

• a lid main body having a left and right lid portions with a drinking aperture located therebetween and spaced apart left and right stop portions positioned above the drinking aperture, the left stop portion being located to the left of the drinking aperture and the right stop portion being located to the right of the drinking aperture;
• a sealing member having a sealing portion and an axle attachment portion, the sealing portion being positioned below the drinking aperture and 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, the axle attachment portion being attached to an upper side of the sealing portion and extending upward through the drinking aperture;
• and
• a camming lever having a cam arm attached to a pair of laterally spaced apart left and right cams to rotate the left and right cams in response to rotation of the cam arm, a laterally extending cam axle positioned between and attached to both of the left and right cams, a left stub axle extending laterally outward from the left cam and a right stub axle extending laterally outward from the right cam, the left cam being positioned to engage the left lid portion and the right cam being positioned to engage the right lid portion, the left stub axle being positioned to engage the left stop portion of the lid main body to limit upward movement of the left stub axle without limiting forward and rearward movement of the left stub axle and the right stub axle being positioned to engage the right stop portion of the lid main body to limit upward movement of the right stub axle while permitting at least limited forward and rearward movement of the right stub axle, the cam axle being in detachable pivotal engagement with the axle attachment portion of the sealing member, the cam arm having a first rotational position whereat the cam axle is in a first position holding the sealing portion of the sealing member in the sealed position and a second rotational position whereat the cam axle is in a second position with the sealing portion of the sealing member in the unsealed position, when the cam axle is detached from the axle attachment portion, the sealing member is separated from the camming lever and rotatable relative to the lid main body independent of the rotational position of the cam arm.

A lid assembly for a drinking vessel, comprising:

• a lid main body having a lid portion with a drinking aperture and a stop portion;
• 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;
• a camming lever having a cam arm attached to a cam to rotate the cam in response to rotation of the cam arm, a laterally extending cam axle attached to the cam and a stub axle extending laterally outward from the cam, the cam being positioned to engage the lid portion and the stub axle being positioned to engage the stop portion of the lid main body to limit upward movement of the stub axle while permitting at least limited forward and rearward movement of the stub axle;
• and
• a connector member extending between and connected to the sealing member and the cam axle, wherein the cam arm has a first rotational position whereat the cam axle is in a first position holding the sealing portion of the sealing member in the sealed position and a second rotational position whereat the cam axle is in a second position with the sealing portion of the sealing member in the unsealed position.

A lid assembly for a drinking vessel, comprising:

• a lid main body having a lid portion with a drinking aperture;
• 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;
• a connector member extending between and connected to the sealing member and the actuator, wherein the actuator has a first rotational position whereat the sealing portion of the sealing member is in the sealed position and a second rotational position whereat the sealing portion of the sealing member is in the unsealed position;
• and
• wherein the sealing portion is positioned below the drinking aperture and the connector member extends upward from the sealing portion through the drinking aperture, the actuator being connected to the connector member at a location above the drinking aperture,
• wherein the actuator is rotatable between the actuator first and second rotational positions, and the actuator includes a cam in engagement with an upper side of the lid portion adjacent the drinking aperture, the cam rotating with rotation of the actuator between the first and second positions of the actuator, rotation of the actuator to the first rotational position causing the cam to rotate and thereby move the actuator to apply an upward force through the connector member to the sealing member to move the sealing portion of the seal member upward into the sealed position, and rotation of the actuator to the second rotational position causing the cam to rotate and thereby move the actuator to apply a downward force through the connector member to the sealing member to move the sealing portion of the sealing member downward into the unsealed position, and
• wherein the lid portion has a stop portion positioned above the drinking aperture, and the cam has a stub axle extending laterally from the cam, the stub axle being positioned to engage the stop portion of the lid main body to limit upward movement of the stub axle while permitting at least limited forward and rearward movement of the stub axle.
