  • Patent number: 5226587
    Abstract: A carton including a hexagonal tray with a complementary hexagonal cover integrally hinged thereto for closing thereover. A dual locking system between the tray and cover includes projecting locking lugs coplanar with the front wall of the tray and extending beyond adjoining tray side walls for interlocking engagement with corresponding lugs on side walls of the cover which extend beyond the cover front wall. The locking assembly also includes headed upwardly extending tabs on selected tray side walls which engage through corresponding slots in the cover top panel to lock the top panel downwardly against the upper edges of the side walls from which the tabs project.

  • Patent number: 4951865
    Abstract: A carton with an integrally hinged tray and cover assembled as a preform and including a lock flange on the front wall of the cover with projecting lock tabs engageable through corresponding slots in the front wall of the tray. The lock flange is gusset-engaged at the opposed ends thereof to the side walls of the cover, and seats on support shoulders on the opposed side walls of the tray to stabilize the flange, and hence the lock tabs thereon, in an extended position for engagement of the tabs within the corresponding slots when the cover is closed.

  • Patent number: 4848648
    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.
