a ring-shaped brim mount adapted to mate with a brim of a drink cup,
a central closure surrounded by the ring-shaped brim mount and including an annular top wall formed to include a top aperture and an adjacent liquid-discharge outlet and an outer wall arranged to extend around an entirety of a circumferential extent of the annular top wall and downwardly from the annular top wall toward an interior region surrounded by the ring-shaped brim mount,
an outlet closure coupled to the annular top wall of the central closure for movement about a horizontally extending pivot axis between a closed position arranged to close the liquid-discharge outlet formed in the annular top wall of the central closure and an opened position arranged to extend away from the liquid-discharge outlet, and
a closure retainer aligned with the top aperture and coupled to the annular top wall of the central closure and configured to retain the outlet closure in a stationary position relative to the outer wall upon movement of the outlet closure from the closed position to the opened position,
wherein at least half of the circumferential extent of the annular top wall has a constant radial width,
wherein the annular top wall includes a radially outer circumferential edge and a radially inner circumferential edge, wherein the outer wall is appended to the radially outer circumferential edge of the annular top wall, and wherein the central closure further includes an inner wall appended to and arranged to extend downwardly away from the radially inner circumferential edge of the annular top wall to a generally annular basin floor, the inner wall extending around an entirety of the circumferential extent of the annular top wall, and
wherein the annular top wall includes a sunken portion located at a rear side of the annular top wall and an elevated portion extending around a remainder of the circumferential extent of the annular top wall and located at a higher vertical height than the sunken portion, the liquid-discharge outlet and the top aperture are formed in the sunken portion, and the sunken portion extends about a quarter of the circumferential extent of the annular top wall.
