Abstract
Abstract A lid adapted to be snaped over a disposable cup filled with coffee has a perforated drinking section along one edge. The top of the lid slopes toward the drinking section so that any liquid spilled or poured on the lid flows back into the cup. Optional radial ridges on the top make it possible to stack one upon the other.
