The carrier has a folded-panel central vertical support structure with a handle and a pair of trays or receptacles attached to the central support structure, and an optional auxiliary tray with a slotted bottom which can be fitted onto the central support panel. A folded side-wall structure can be unfolded to start the formation of the trays, and a plurality of folded flanges unfold to form a bottom for each receptacle. Dividers separate each receptacle into the three compartments to hold six beverage or other containers in the trays or receptacles. The carriers can be made from a single sheet and advertising printed entirely on one side to facilitate efficient fabrication at a moderate cost.
