Abstract
Abstract A paperboard container includes inserts permitting compartmentizing of the container. The inserts may be glued or heat-sealed to the interior side walls and/or end walls of the container. The container may be composed of double-faced or solid fiber paperboard and the interior and exterior thereof may be curtain coated with a low viscosity plastic in order to provide a moisture and sulfur barrier. The curtain coating also provides a grease-resistant barrier. The inserts may be composed of plastic which may be vacuum formed, injection molded, or otherwise thermoformed into the desired shape or may be composed of compressed fiber. The inserts have slots or grooves formed therewith adapted to receive partitioning members therein. The inserts may be color coded to facilitate insertion of partitioning members into aligned slots.
