1. A spill proof-lid for a container that contains a plurality of items accessed through the mouth of the container, the lid comprising:

  • a rim formed about an axis, the rim having a top end, a bottom end and a portion for coupling the rim to the mouth of the container;

    a frustoconical flange extending downwardly and inwardly from the top end of the rim, the frustoconical flange having an annular bottom end spaced radially from the rim to provide an inner trough therebetween, the bottom end surrounding an opening to access the items in the container, and a plurality of flexible resilient flaps extending from one location at the bottom end of the rim inwardly toward the axis of the rim, the flaps terminating at free ends positioned at least in proximity with the axis such that said flaps normally provide a closure of the opening by being biased to the closed position, and the flaps each having convex outer surfaces defining an outer trough adjacent the frustoconical flange such that when said lid is coupled to the mouth of the container containing said items said items are removable from the container by insertion of a hand through the opening to deflect the flaps and to allow withdrawal of items through the opening, the flaps reclosing the opening after items have been removed therethrough with the inner and outer troughs, respectively, retaining items behind the lid when the lid is tilted and retaining items on top of the lid when spilled thereon.
