1. A container lid comprising:
a lid body comprising a flared perimeter wall, an inner structure, and a perimeter well,
wherein the perimeter well is at least partially defined by an inner surface of the flared perimeter wall, the flared perimeter wall having a first end and an opposite second end, the first end and the second end defining a longitudinal axis;
wherein the inner structure defines a central throat, an outer circumferential surface of the central throat being radially spaced from the inner surface of the flared perimeter wall;
wherein the central throat defines an aperture extending through the lid body, and
wherein the perimeter well defines a plurality of openings disposed around the central throat;
a lid body seal disposed about the lid body; and
a lid upper comprising:
a lid base; and
a lid roof secured to the lid base, wherein the lid base is lockably received within the aperture of the central throat, at an inner circumferential surface of the central throat,
wherein when the lid base is lockably secured in the aperture of the central throat, the lid roof partially covers the perimeter well,
wherein a bottom surface of the perimeter well pitches downward from the inner structure towards the flared perimeter wall,
wherein the plurality of openings are defined by the perimeter well proximate a lowermost extent of the perimeter well,
wherein the lid body further comprises an inner shelf projecting inward from the flared perimeter wall towards the perimeter well,
wherein the lid roof comprises an outer perimeter disposed at least partially above the inner shelf,
wherein an underside of the lid roof is concave,
wherein an apex of the lid roof is disposed below an upper extent of the lid body,
wherein the lid roof is separated from the inner shelf by a gap, the gap fully extending circumferentially around the longitudinal axis,
wherein the lid roof is spaced from the well wall such that a splash chamber is defined thereby, the splash chamber fully extending circumferentially around the longitudinal axis,
wherein an inlet to the splash chamber is defined by the plurality of openings and an outlet for the splash chamber is defined by the gap,
wherein a nonlinear flow path is defined through the splash chamber, and
wherein the liquid flow path is always open, and the gap is not covered.
