Abstract
Various embodiments of flanged containers that can be stacked in a nested relationship are disclosed so as to provide uniform spacing between the containers to facilitate reliable denesting thereof. The flanges and/or sidewalls of the containers may be provided with features that facilitate alignment and uniform spacing of the nested containers so that a denesting apparatus can reliably denest the containers. Other containers include sidewalls divided into two sections that serve to stabilize stacked container.

- and
- a denesting feature formed in the flange, the denesting feature enhancing denestability of the container;
- wherein the denesting feature comprises an inner peripheral portion of the flange that is adjacent to the sidewall and that is thicker than an outer portion of the flange, the thicker inner peripheral portion extending a majority of the distance around the flange.
