Title: Disposable servingware with nesting resistant flange patterns

Abstract: Stackable servingware is provided with repeating flange patterns configured to resist nesting and taper lock. The patterns include a first pattern which is chiral with respect to a second pattern such that the patterns are not superimposable on one another. Preferably, the servingware is packaged in alternating sequence such that each article in a stack has a flange pattern which mirrors the flange pattern of adjacent articles.
