Abstract
A disposable child's drinking cup has a lid with a drinking spout defining multiple open holes sized to resist leakage in the absence of suction, such as by the development of surface tension at the holes, and to allow flow when suction is applied. The holes are formed during molding of the lid. An inner contour of a groove of the lid and an outer contour of the cup body rim are selected to provide a slight snap fit of the lid onto the cup body, to provide a secure seal.
