Nestable molded articles, and related assemblies and methods
A man-made, molded article is provided. The article includes a profile including a planar wall, and an adjacent integral molded depression having a contoured wall extending downwardly from the planar wall. The contoured wall includes a bead portion, a cove portion, and a ledge between the bead and cove portions. The articles are stackable, one above another for transport, in a nestable relationship in which multiple contact zones are present between the contoured walls of an adjacently stacked pair of the molded articles. The contact zones include an arcuately extending contact interface zone between the bead exterior and interior surfaces. The depression has a substantially uniform thickness varying by no more than about +1 percent to about −11 percent in relation to a thickness of the planar wall. Related methods and assemblies are also provided.
