1. A rotating lid assembly for sealing a container with an open end, the rotating lid assembly comprising:

  • a lower base portion adapted to engage the open end of the container, wherein the lower base portion comprises a first upper surface with a first axis, a downwardly extending first circumferential wall intersecting the first upper surface, a first dispensing opening housed within a well in the first upper surface, a raised sealing lip disposed at least partially around a periphery of the well, a spring bore in the first upper surface disposed substantially coaxially with the central axis, a plurality of circumferential guide ridges disposed about the first circumferential wall, and a spring adapted to fit within the spring bore and be secured therein;

    the lid assembly further comprising an upper sealing portion adapted to at least partially surround the first circumferential wall of the lower base portion, the upper sealing portion being adapted to selectively expose the first dispensing opening of the lower base portion when rotated from a closed position to an open position, wherein the upper sealing portion comprises;

    a second upper surface, a downwardly extending second circumferential wall intersecting the second upper surface, and an upper dispensing opening in the second upper surface, the upper dispensing opening substantially aligning with the lower dispensing opening when the upper sealing portion is in the open position, an extension element projecting downwardly from the second upper surface adapted to engage said spring, and a circumferential guide groove cut into the circular interior surface and adapted to engage the circumferential guide ridges so as to lower the second upper surface and thereby sealably engage the second side of the second upper surface against the sealing lip when the upper sealing portion is in the closed position, the upper sealing portion being normally biased to the closed position by the spring such that a sealed relation is maintained around the well in the absence of an applied opening force.
