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.

Claims

1. A carton folded from a one-piece blank of paper board, said carton comprising multiple longitudinally aligned compartments, a transverse partition between each adjacent pair of compartments, each compartment including a base panel with longitudinally extending planar side walls integrally folded upward from opposed sides of the base panel and terminating in free upper edges, each said transverse partition being attached to the base panels of the adjacent compartments, glue flaps bonding said partition to the side walls of the adjacent compartments below the free upper edges of said side walls, each side wall adjacent the partition having a substantially coplanar longitudinally extending extension vertically above the glue flaps and overlapping a similar extension on an aligned side wall of the adjacent compartment, means rigidly securing the overlapped extensions to each other to preclude movement between the corresponding side walls, said compartments including endmost compartments, and carton end walls extending transversely across the endmost compartments between the side walls thereof.

2. The carton of claim 1 including at least three longitudinally aligned compartments.

3. The carton of claim 1 wherein said side walls and end walls are of a greater height than each said partition, and a closure lid overlying said compartments and engaging each said partition, said lid having peripheral walls closely received within the walls of the carton above the height of each said partition.

4. The carton of claim 1 including a lid, hinge means integrally hinging the lid to and along the upper edge of one of said end walls for selective pivotal closure over the carton, a tab extending from the end wall remote from the lid along the upper portion thereof, said lid including an end wall remote from said hinge means, said lid end wall having a slot defined therethrough selectively receiving said tab upon closure of the lid.

5. The carton of claim 4 wherein the carton end wall remote from the lid is laterally flexible for a sliding engagement with the lid end wall and a snap locking of the tab within the slot.

6. In a carton folded from a blank, multiple longitudinal aligned adjacent compartments, each compartment including a base panel having opposed first and second longitudinal edges and opposed transverse edges, a longitudinal planar side wall panel integral with and upwardly extending from each base panel along and generally coextensive with each longitudinal edge thereof, the side wall panels along each of the first and second longitudinal edges of the compartments being in general longitudinal alignment, a transverse partition section upwardly folded between base panels of adjacent compartments and adjacent transverse edges thereof, said partition section having a central fold area longitudinally therealong defining a partition panel to each side thereof, each partition panel being integral with the adjacent transverse edge of an adjacent base panel and defining a transverse wall of the corresponding compartment, said partition panels diverging downward from the central fold area therebetween, the side wall panels aligned along each of the longitudinal edges of the adjacent compartments having adjacent end portions, said partition section having a pair of glue flaps at each end thereof, said glue flaps extending parallel to the side wall panels and into overlapping bonded engagement with the adjacent end portions of the side wall panels of the adjacent compartments, each of said adjacent end portions of the side wall panels having an integral extension upward of and parallel to the glue flaps and extending longitudinally beyond the end portion and into overlapping joined engagement with the aligned side wall panel of the adjacent compartment to rigidly join the aligned side wall panels of adjacent compartments and preclude movement therebetween, said compartments including opposed endmost compartments, each including a transverse outer end wall panel integral with and upwardly extending from the corresponding base panel, each of said end panels including opposed ends bonded to the side wall panels of the corresponding endmost compartments.

7. The carton of claim 6 wherein said side wall panels and said end wall panels diverge upwardly from the base panels.

8. Carton of claim 6 including at least three longitudinally aligned compartments with a transverse partition section between the base panels of each adjacent pair of compartments.

9. The carton of claim 6 wherein one of said outer end wall panels includes an upper edge, a hinge panel extending along said upper edge and being integral therewith along a defined hinge line, and a lid panel integral with said hinge panel along a fold line parallel to said hinge line for selective folding of the lid panel into overlying relation to the multiple compartments.

10. The construction of claim 9 wherein said lid panel is of greater longitudinal length than the multiple longitudinally aligned compartments and of a greater transverse width than said compartments.

11. The construction of claim 10 including an end wall panel integral with and upwardly folded from the lid panel along a fold line parallel to and remote from said hinge panel.

12. The construction of claim 6 including a closure lid overlying said compartments, said lid including peripheral walls.

13. The construction of claim 12 wherein said lid walls are receivable about the carton outward of the compartment side walls.

14. The construction of claim 12 wherein said lid walls are receivable within the compartment walls.
