Abstract
Abstract A stackable packaging container having an open top and a body portion tapering inwardly from the top to the bottom has a rim formed by an outwardly extending peripheral flange and a downwardly dependent flange depending from the outward flange to be spaced from the body portion. De-nesting recesses are formed in the downwardly dependent flange of the rim to prevent the containers jamming inside one another when stacked, the recesses not interrupting the smooth inner wall of the body portion.
