Abstract

A produce container comprises a bottom wall, a pair of opposing side walls, a front wall, and a back wall. The front and back walls are reinforced along their tops by partial rollovers, each of which comprises two flanges--a center flange and a major flange--hingedly attached to the wall being reinforced. Each rollover is formed by first folding the center flange slightly away from the major flange and then folding the major flange downward toward the corresponding wall. Folding the major flange captures the center flange and at the same time forms doubled, indexed stacking tabs whose tops are formed along the axis about which the major flap is folded. The corners where the side walls and front and back walls join are reinforced by corner structures, with the corner structures extending along a portion of each of the joining walls so that the corners are reinforced along each wall with at least two layers of vertically-corrugated paperboard. The corners are further reinforced by shoulders extending across the top of the container at the corners and affixed to the side walls and the front and back walls where they join. The shoulders extend a short distance inward toward the center of the box and, in addition to reinforcing the corners, serve to prevent stacked containers from nesting.
