Abstract: A blank for making a single or dual cavity container and the corresponding containers. In a dual cavity embodiment, the blank is scored to define a pair of bottom panels, two pairs of end panels, and a pair each of lateral and opposing side panels. The pair of opposing side panels are connected together along a mutual upper edge. A lid for each respective cavity extends from the first and second lateral side panels, and each lid terminates in a tuck flap for engaging at least one of the corresponding opposing side panels and the corresponding pair of end panels. Each adjacent pair of walls (e.g., end panel-lateral side panel; end panel-opposing side panel) has a gusset integrally formed therebetween. The gussets are appropriately folded and adhered to the outside of one of the adjacent walls. Because both cavities are formed from a unitary blank with no seams below the upper edges of the walls, leakage is prevented when the container is maintained in an upright orientation.
