STACKABLE CONTAINER HAVING SUPPORT FLANGES

摘要

Containers are disclosed having a plurality of interconnected panels forming sidewalk surrounding a central space. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. Support flanges are arranged along upper sidewall edges on oppositely facing sidewalls. The support flanges are oriented at right angles to the sidewalls and provide a support surface allowing the containers to be stacked one atop another without collapsing or nesting within each other. Side flanges are attached to each end of the support flanges and to sidewalls joined to the sidewalls having the support flanges. The side flanges each have an angularly oriented fold line which divides the side flanges into facing portions and permits them to fold like a bellows or accordion pleat. The facing portions are adhered together to hold the support flanges in position.
