Abstract
A tote container assembly having a pair of support panels, each support panel being formed from a corrugated plastic material and having a longitudinal grain. The support panels are positioned with their grains perpendicular to one another, and each panel is folded into a U-shape. The edges of the panels are fastened by sonic welds over a wire rim member which extends around the top peripheral edge of the tote container, and defines a pair of handgrips on opposing sides of the container. The corners of the rim member are curved to present stacking shoulders at the top corners of the container.
