Abstract
A three position, selectively openable twist lid for a drinking vessel has separate drinking and venting apertures. The lid has two parts—a base member and a cap member. The base and cap members can be relatively rotated from a first, closed position to a second, open position and to a third, disengaged position in which the cap and base members may be separated for cleaning.
