Abstract
A lid for use on a cup having a radially outwardly projecting non-helical brim extending around a mouth thereof. The lid is formed of plastic and comprises a center portion, and a flexible skirt extending downwardly from an outer periphery of the center portion. The skirt includes a radially inwardly projecting annular restriction ring adapted to be positioned beneath the cup brim. The skirt includes a plurality of threads spaced apart circumferentially around the skirt. Each thread extends generally helically upwardly from a location disposed between the restriction ring and a bottom edge of the skirt. The threads intersect the restriction ring to form circumferentially spaced caesurae in the restriction ring.
