Claim 15:
16. A reclosable cup lid, comprising:
an upper surface;
a first recess formed within the upper surface, wherein the first recess has curved ends and an arcuate shape, a first radius of curvature, R1, and a second radius of curvature, R2, wherein a ratio of R1:R2 is about 1:1.1 to about 1:2.5;
a tab configured to fit within the first recess, the tab having curved ends and an arcuate shape that correspond to the curved ends and arcuate shape of the first recess and further comprising a first radius of curvature, R3, and a second radius of curvature, R4, wherein a ratio of R3:R4 is about 1:1.1 to about 1:2.5;
a second recess formed within the upper surface to provide a space for a user's nose; and
an opening disposed within the first recess to allow fluid flow therethrough, wherein the tab and the first recess have corresponding s-shaped profiles to provide a friction fit therebetween such that the tab is able to move within the first recess from a first position to a second position so that the opening is at least partially blocked when the tab is located in the first position, and the opening is unobstructed when the tab is located in the second position.
