A two-piece beverage carrier is disclosed comprising a one-piece folded longitudinal partition insert which is adhesively secured to the end panels and to the bottom panel of a separate paperboard shell. The shell may be constructed as a wrap-around carrier or it may be constructed in the form of a basket style. The insert for either type of shell has formed thereon a plurality of transverse butterfly partition panels which also have formed thereon glue tabs for adhesively securing the butterfly partitions to the side panels of the paperboard shell. The insert utilizes a low caliber, single thickness of paperboard in formation of the production blank and by the structure and outline of the butterfly partition panels, heavier thickness is obtained between cells of the erected carrier.
