The invention relates to a carton for carrying a plurality of cylindrical cans arranged in parallel rows. The carton is made from an integral blank, suitably cut and scored so that it can be folded into a sleeve to receive a group of cans. The sidewalls of the carton are provided with window openings. The upper edges of the window openings and the edges of the bottom flaps and end walls of the carton are cut in a zig-zag or wave fashion so that the upper edges, bottom flap edges and end wall edges, in loading the cans into the carton, slide down over the beads of the cans without interference.
