Abstract

Abstract A package for taco shells of the type which are a thin crisp tortilla of a generally circular shape which is folded upon itself leaving a radius of curvature across the folded mid section of the taco shell. The package includes a nested array of the shells which are located within a tray having two diagonally oriented and inwardly folded flaps which position the shells against one another in the nested array and which, in combination with a shrink film covering over the taco shells and the tray, reduces breakage of the shells during shipment and storage.
