1. 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;

    at least one cover portion having at least one item-covering concavity for covering the frangible items, the cover portion having a generally flat top wail and peripheral walls concurrently defining the at least one item covering concavity;

    a first hinge between the base portion and the cover portion for rotation of the cover portion onto the base portion to hold the frangible items captive in the item-receiving cavities;

    at least one abutment spacer formed proximate an edge between the peripheral walls and the top wall, the at least one abutment spacer comprising an abutment surface projecting into the concavity from one of the peripheral walls, and support walls relating the abutment surface to the top wall, at least one of the support walls being in an acute angle relation with the top wall; and

    at least one alignment channel in at least one of the peripheral walls defining an alignment protrusion through the sheet of polymer, the alignment channel being vertically offset from the at least one abutment spacer and oriented vertically to guide nesting of the cover portion into a similarly-configured cover portion with the alignment protrusion of the cover portion received in the alignment channel of the similarly-configured cover portion to form a stack of nested containers in an open position, whereby a spacing between the nested containers is defined by the at least one abutment spacer of the cover portion seated on the at least one abutment spacer of the similarly-configured cover portion, wherein the alignment channel has a projecting edge configured to hold a label captive in the cavity between the alignment protrusion of the cover portion and the alignment channel of the similarly-configured cover portion when the cover portion and the similarly-configured cover portion are nested together.
