The invention relates to a container carrier with a flexible flange. The container carrier and manufacturing method for a container carrier are provided. The container carrier includes an integrally molded body with a plurality of annular structures connected by a bridges. The annular structures each include a side wall formed of side wall portions separated by side wall voids and a top surface. Flanges are positioned at the bottom of each side wall void to collectively engage the containers. The flanges are configured to project inwardly and orient upwardly at an angle so as to flex when accepting or releasing a container. The top surfaces of the annular structures include notched voids continuous with respective side wall voids such that the flanges positioned at the bottoms of the sidewall voids are accommodated by the notched voids in the top surface of a second, same-shaped container carrier when stacked.
