ABSTRACT:
An upwardly open container has a flat base with upper and lower sides and an outer peripheral edge defining a predetermined shape. An array substantially of this shape of generally parallel strips extending generally perpendicularly upwardly from the base defines the sides of the container with each of the lower ends of each of the strips secured to the outer peripheral edge. These strips each have a predetermined width measured parallel to the edge and a predetermined thickness measured perpendicular to the edge, and are equispaced apart along the edge by a distance equal to at least this width. A flat rim has an inner edge of the above-mentioned shape and larger in at least one direction parallel to the base than the corresponding portion of the peripheral outer edge of the base by a difference equal to at least twice the strip thickness. The upper ends of these strips are secured to the inner edge. Thus at least two of these containers can nest within each other with the lower face of the base of the upper container resting on the upper face of the base of the lower container and the strips of the containers interleaved. The base, rim, and arrays may be circular and angular. It is also possible for the shape to be a pair of parallel lines formed by opposite sides of a rectangular base and rim having another closed side and an open side. The distance between adjacent strips is a whole-number multiple of the strip width for nesting of a plurality of such containers together.
