ABSTRACT:
A multi-compartment carton folded from a unitary cardboard blank and including a central partition defined by a pair of generally spaced partition panels. The opposed ends of the partition section incorporate laterally directed glue flaps which adhesively bond to opposed aligned pairs of side walls. The side walls, along each side of the formed compartments, in turn include projecting integral extensions which overlie and bond to each other above and independently of the glue flaps to provide a rigid interlock of the aligned walls and a rigid fixing of the compartments relative to each other. Closures, either unitary with the blank of the carton or as separate lids, close and segregate the defined compartments.
