2. A carton in accordance with claim 1, further comprising at least one cut-out extending upwardly from each of the end edges of the bottom panel, the at least one cut-out extending into at least a portion of at least one end of the two end panels.

3. A carton in accordance with claim 1, further comprising stacking tabs emanating upwardly from the top edge of at least one of a side panel of the two side panels and an end panel of the two end panels.

4. A carton in accordance with claim 1, wherein each first outer overlap panel is in overlying relation to an adjacent side panel of the two side panels.

5. A carton in accordance with claim 1, wherein each second outer overlap panel is folded relative to its respective first outer overlap panel and positioned in substantially parallel, at least partially overlying relation to the exterior surface of at least one of the minor panels.

6. A carton in accordance with claim 1, wherein the at least one top panel is operably positioned upon articulation in substantially spaced, parallel, overlying relation to at least a portion of the bottom panel, the at least one top panel, being substantially maintained in said overlying position over at least a corner region of the carton when positioned in the substantially spaced, parallel, overlying relation to the at least a portion of the bottom panel.

7. A carton in accordance with claim 6, wherein each corner region of the carton is defined by one of the two side panels, one of the minor panels and one of the two end panels.

8. A carton in accordance with claim 1, further comprising:

stacking tabs emanating upwardly from the top edges at least one of the side panels and the end panels; and

stacking tab apertures disposed in at least one of the bottom panel, bottom edge regions of the side panels, and bottom edge regions of the end panels, wherein each stacking tab aperture of the carton is configured to receive a corresponding stacking tab of a second carton when the carton is positioned on top of the second carton.

9. A carton in accordance with claim 1, wherein each minor panel of the two minor panels comprises a miter panel and an inner end panel, the inner end panel affixed at least indirectly to the inside surface of the adjacent one of the two end panels.

10. A carton comprising:

a bottom panel having at least a first side edge region and at least a first end edge region;

at least a first side panel having at least a first minor flap emanating from an end edge of the at least first side panel operably connected to the at least first side edge region of the bottom panel;

at least a first end panel operably connected to the at least first end edge region of the bottom panel, wherein the at least first side panel, the at least first minor flap, and the at least first end panel being operably arranged with respect to one another to define at least a first corner region of the carton;

at least one top panel connected to the first end panel and operably positioned in an open position and a closed position, the at least one top panel being substantially maintained in said overlying position over the at least first corner region when positioned in the closed position; and

at least one corner support assembly operably emanating from the at least one top panel and configured to provide vertical loading support for the carton, wherein said at least one corner support assembly comprises;

a first outer overlap panel operably emanating from the at least one top panel and being operably positioned in substantially parallel, at least partially overlying relation to an outer surface of the first side panel;

a second outer overlap panel emanating from a side edge of said first outer overlap panel, said second outer overlap panel being folded relative to said first outer overlap panel and operably positioned in substantially parallel, at least partially overlying relation to an exterior surface of the at least first minor flap; and

an overlap panel connection structure extending between the at least one top panel and the first outer overlap panel, wherein said overlap panel connection structure is configured to enable the first outer overlap panel to be affixed in place without interfering with movement of the at least one top panel.

11. A carton in accordance with claim 10, further comprising:

stacking tabs emanating upwardly from a top edge of at least one of said at least first side panel and said at least first end panel; and

stacking tab apertures disposed in at least one of the bottom panel, bottom edge regions of the at least first side panel, and bottom edge regions of the at least first end panel, wherein each stacking tab aperture of the carton is configured to receive a corresponding stacking tab of a second carton when the carton is positioned on top of the second carton.
