1. A lid for a cup, the lid comprising
a ring-shaped brim mount adapted to couple to a brim included in a cup,
a closure coupled to the ring-shaped brim mount, and
a deformable dome coupled to the closure, the deformable dome arranged to move from a first arrangement in which the deformable dome extends upwardly away from the closure to a second arrangement in which the deformable dome is arranged to extend downwardly away from the closure in response to a downward deformation force being applied to the deformable dome,
wherein the lid comprises a polypropylene copolymer and the deformable dome has a first transparency in the first arrangement and a second transparency in the second arrangement and the second transparency is different than the first transparency,
wherein the lid comprises at least 49% by weight the polypropylene copolymer,
wherein the first transparency is defined at least by a clarity as measured using ASTM D 1746 and a haze as measured using ASTM D 1003 procedure B and a ratio of the clarity to the haze is greater than 1:1.
