Spill prevention system for drinking cup

A removable lid for a drinking cup, the removable lid comprising:

• a top side with a substantially circular periphery;
• a sidewall extending from the periphery;
• an annular mounting portion extending from an edge of the sidewall and configured to removably attach to an open side of a drinking cup;
• and
• an ellipsoidal recession, located adjacent to the periphery of the top side, with a bottom opening, and a baffle wall connected along a perimeter of the bottom opening and extending away from the top side,
• wherein the baffle wall is configured to block a beverage from passing through the bottom opening and into the ellipsoidal recession upon a sudden movement of the beverage, and wherein the baffle wall comprises holes, and slants straight and downwards away from the periphery of the top side,
• wherein an intersection of the ellipsoidal recession and the top side forms a generally elliptical shape having a long axis to short axis length ratio of 1.5:1-1.9:1 and wherein the short axis is aligned towards a central region of the top side,
• wherein the ellipsoidal recession is configured to collect the beverage from the bottom opening prior to consumption, allow an ingredient to pass through the bottom opening to the beverage, or both, and
• wherein the top side is a generally planar surface foil ling an angle of 4°-15° with a plane circumscribed by the annular mounting portion so that a height of the sidewall decreases as a distance from the ellipsoidal recession increases along a diameter of the lid.
