Stacking configuration for container for frangible items

A container for receiving frangible items comprising:

• a sheet of polymer formed into:
• a base portion having a plurality of item-receiving cavities for supporting frangible items, the item-receiving cavities each having a generally frustoconical shape flaring upwardly;
• at least one cover portion having at least one item-covering concavity for covering the frangible items;
• a first hinge between a first longitudinal edge of the base portion and the cover portion for rotating the cover portion onto the base portion to hold the frangible items captive in the item-receiving cavities;
• and
• a projection with an abutment surface in at least one of the item-receiving cavities, the abutment surface being on a side of the item-receiving cavities facing outwardly from the container, the abutment surface extending upward from a bottom of the item-receiving cavities and facing outward of the container, the abutment surface being perpendicular to a ground when the container is laid on the ground, and the abutment surface being parallel to the first longitudinal edge of the container.

A container for receiving frangible items comprising:

• a sheet of polymer formed into:
• a base portion having a main top wall lying in a single plane, a plurality of item-receiving cavities projecting downwardly from the main top wall for supporting frangible items, the item-receiving cavities having a frustoconical portion having a generally frusto-conical geometry, each item-receiving cavity being separated from at least one other said item-receiving cavity by the main top wall, each item-receiving cavity merging into the main top wall by an arcuate edge from a top plan view, the arcuate edge covering at least a quarter of a periphery of each said item-receiving cavity;
• at least one cover portion having at least one item-covering concavity for covering the frangible items;
• and
• a first hinge between a first longitudinal edge of the base portion and the cover portion for rotating the cover portion onto the base portion to hold the frangible items captive in the item-receiving cavities.
