Abstract

A stackable shipping container for shipping articles such as produce, which is open-topped. The shipping container is preferably provided with stacking indexing tabs configured to be received by corresponding slots in the bottom of a like container stacked atop a first such container. Inwardly inclined diagonal corner gussets are provided for providing support of the bottom of a container stacked above one such container, while increasing available container volume.

5. The stackable shipping container according to claim 4, wherein the fold lines defining the nonrectangular gusset panels do not intersect within the blank.

6. The stackable shipping container according to claim 4, wherein the fold lines defining the nonrectangular gusset panels intersect at the edge regions of the blank.

7. The stackable shipping container according to claim 4, wherein the fold lines defining the nonrectangular gusset panels intersect at positions inwardly removed from edge regions of the blank.

8. The stackable shipping container according to claim 1, further comprising:

one or more stacking tabs defined by cutout regions disposed between the first pair of opposed first sidewalls and respective ones of the pair of opposed second sidewalls; and

one or more stacking tab receiving apertures disposed in the bottom wall.

9. The stackable shipping container according to claim 8, wherein the one or more stacking tabs of the stackable shipping container are configured to cooperate with and be insertingly received by the slots of a similar stackable shipping container stacked atop the stackable shipping container.

10. The stackable shipping container according to claim 3, wherein the first and second minor flaps emanate from the first pair of first side walls and the pair of second sidewalls, respectively, by inclined fold lines, so that upon articulation of the blank, the second pair of first sidewalls are also inwardly inclined with respect to the bottom wall.

11. A blank for a stackable shipping container, comprising:

a substantially rectangular bottom wall having two perpendicularly arranged pairs of opposed side edge regions;

first and second pairs of opposed first sidewalls, emanating from the two perpendicularly arranged pairs of opposed side edge regions;

pairs of first minor flaps, emanating from second edge regions of each of the first pair of opposed first sidewalls;

pairs of second minor flaps, connected to third edge regions of each of the pair of opposed second sidewalls,

nonrectangular gusset panels, disposed substantially between the second minor flaps and the respective adjacent end edge regions of the respective second sidewalls,

the first and second pairs of opposed first sidewalls, the pair of opposed second sidewalls, and the pairs of first minor flaps and pairs of second minor flaps being operably configured, upon articulation, so that each of the second sidewalls is folded inwardly, in juxtaposed overlying relation to an inside surface of a respective one of the first pair of first sidewalls, each of the first minor flaps is in juxtaposed overlying relation to an inside surface of a respective adjacent one of the second pair of first sidewalls, and each of the second minor flaps is in juxtaposed overlying relation to an inside surface of a respective one of the first minor flaps;

the nonrectangular gusset panels being provided with a top region having a width that is greater than the width at a bottom region thereof, so that upon articulation of the blank, the nonrectangular gusset panels extend diagonally across corner regions of the stackable shipping container, with the top regions of the nonrectangular gusset panels extending farther inwardly into an interior region of the stackable shipping container than the bottom regions of the nonrectangular gusset panels.

12. The blank according to claim 11, wherein one pair of first sidewalls is longer than the other pair of first sidewalls.

13. The blank according to claim 11, wherein the first and second minor flaps have angled bottom edges so that upon articulation of the blank, at least the first pair of first side walls and the pair of second sidewalls are inwardly inclined with respect to the bottom wall.

14. The blank according to claim 11, wherein the nonrectangular gusset panels are defined by pairs of fold lines disposed between the second minor flaps and the respective adjacent end edge regions of the respective second sidewalls, in which the fold lines have an acute angle subtended between them.

15. The blank according to claim 14, wherein the fold lines defining the nonrectangular gusset panels do not intersect within the blank.
