Patent attributes
A lid assembly for attachment to a drinking vessel is provided having a camming lever rotatably attached to an upper portion of a lid main body, and a sealing member rotatably attached to a lower portion of lid main body. Rotation of the camming lever between a forward and rearward position in an elongated recess of the lid main body selectively seals and unseals a drinking aperture in the lid main body. A locking member is operable to selectively secure the rotational position of the camming lever when the sealing member is in a sealing position sealing the drinking aperture. A cam axle of the camming lever is removably attachable to an attachment element of the sealing member to transition the lid assembly between a use configuration for drinking and a cleaning configuration in which the lid assembly may be thoroughly cleaned.
