Abstract
A splash-proof lid for a drinking cup has a splash guard in the form of a semi-permeable membrane positioned between the liquid contents of the cup and a discharge opening of the lid. The splash guard inhibits the liquid from splashing out of the discharge opening, while permitting the liquid to flow therethrough to the discharge opening.
