A container carrier for securing together and carrying multiple containers comprising: an integrally molded body including a plurality of annular structures, wherein each annular structure is connected by a bridge to at least one adjacent annular structure of the plurality of annular structures; wherein each annular structure includes a side wall formed of side wall portions separated by side wall voids formed in the side wall, and a top surface connecting the side wall portions; wherein a respective flange is positioned proximate a bottom end of each side wall void; wherein the flanges of each annular structure are collectively configured to releasably engage a corresponding container of the multiple containers; wherein the flanges project inwardly and are configured to flex when accepting or releasing a corresponding container of the multiple containers; wherein an internal perimeter of each flange 30 is formed to have an arcuate shape centered on a central axis of the top surface which conforms to a curvature of a neck of a corresponding container of the multiple containers; wherein the top surface connecting the side wall portions of each annular structure includes notched voids continuous with respective side wall voids such that the flanges positioned proximate the bottom ends of each side wall void are accommodated by the notched voids in the top surface of a second, same-shaped container carrier when stacked; and wherein the flanges have a perimeter profile as viewed from above that is smaller and nests within a perimeter profile as viewed from above of the notched voids in the top surface, characterized in that the flanges are oriented upwardly at an angle of inclination from horizontal greater than 10 degrees and less than 30 degrees. an integrally molded body including a plurality of annular structures, wherein each annular structure is connected by a bridge to at least one adjacent annular structure of the plurality of annular structures; wherein each annular structure includes a side wall formed of side wall portions separated by side wall voids formed in the side wall, and a top surface connecting the side wall portions; wherein a respective flange is positioned proximate a bottom end of each side wall void; wherein the flanges of each annular structure are collectively configured to releasably engage a corresponding container of the multiple containers; wherein the flanges project inwardly and are configured to flex when accepting or releasing a corresponding container of the multiple containers; wherein an internal perimeter of each flange 30 is formed to have an arcuate shape centered on a central axis of the top surface which conforms to a curvature of a neck of a corresponding container of the multiple containers; wherein the top surface connecting the side wall portions of each annular structure includes notched voids continuous with respective side wall voids such that the flanges positioned proximate the bottom ends of each side wall void are accommodated by the notched voids in the top surface of a second, same-shaped container carrier when stacked; and wherein the flanges have a perimeter profile as viewed from above that is smaller and nests within a perimeter profile as viewed from above of the notched voids in the top surface, characterized in that the flanges are oriented upwardly at an angle of inclination from horizontal greater than 10 degrees and less than 30 degrees.
