A container for receiving frangible items comprising a sheet of polymer formed into: a base portion and at least one cover portion with a hinge between the base portion and the cover portion. Abutment spacer are formed at an edge between the peripheral walls and the top wall and each comprise an abutment surface projecting into the concavity from one of the peripheral walls, and support walls relating the abutment surface to the top wall, with at least one of the support walls being in an acute angle relation with the top wall of the cover portion. Alignment channels are in at least one of the peripheral walls defining an alignment protrusion through the sheet of polymer, the alignment channel/protrusion being oriented vertically for guiding the nesting of an upper one of the cover portion descending into a lower one of the cover portion.

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; andat 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. 2. The container according to claim 1, wherein the abutment surface of the at least one abutment spacer is parallel to the top wall. 3. The container according to claim 1, wherein the edge proximate the at least one abutment spacer is disposed between the top wall and the peripheral wall opposite the first hinge. 4. The container according to claim 3, comprising two of said abutment spacer, the abutment spacers being located at opposed ends of the edge. 5. The container according to claim 1, comprising a plurality of the alignment channels, at least one of the plurality of alignment channels being disposed in each of said peripheral walls. 6. The container according to claim 1, wherein at least one edge of the at least one alignment channel tapers toward the top wall. 7. The container according to claim 1, further comprising a label in the concavity and covering at least partially the top wall and the peripheral walls. 8. The container according to claim 1, wherein the at least one alignment channel is disposed in the concavity, and the alignment protrusion is disposed on an exterior surface of the top cover portion. 9. The container according to claim 1, wherein the base portion has a post centered between each set of four of the item-receiving cavities, the post projecting upwardly from the base portion to support a structural component of the cover portion when the container is closed, and further comprising post spacers formed between at least one of the posts and the four item-receiving cavities surrounding the post, the post spacers each defining a subcavity on one side of the sheet of polymer and a bump on the other side of the sheet of polymer, the post spacers having a wider central portion for narrower ends along a vertical axis of the container, such that the nesting of an upper one of the base portion descending into a lower one of the base portion results in the post spacers of the upper one seated on the spacers of the lower one when a stack of the containers in an opened state is formed, whereby a spacing between nested base portions is defined at least by the post spacers of the upper one seated on the post spacers of the lower one. 10. The container according to claim 9, wherein the post spacers each have a teardrop shape. 11. The container according to claim 9, wherein the subcavities are disposed inside the container, and the bumps are disposed on an exterior surface of the base portion. 12. The container according to claim 1, further comprising: two of the cover portion, with an intermediate one of the cover portions having item-covering cavities for covering the frangible items on the item-receiving cavities; a second hinge between the second longitudinal edge of the base portion, and the intermediate cover portion for rotating the intermediate cover portion onto the base portion, a top one of the cover portions being hinged about the first longitudinal edge to hold the base portion, the intermediate cover portion and the top cover portion in a closed configuration. 13. The container according to claim 1, wherein the frangible items are eggs, and each of the egg-receiving cavities receives one egg.
