This disclosure relates to a cover for a group of containers adapted to be formed into a package by wrapping sheet material thereabout. The cover is formed of paperboard having grain with the cover being naturally warpable about the grain axis. The cover further has flaps connected to opposite sides thereof and extending normal to the grain axis with the flaps being foldable out of the plane of the cover to provide the cover with beam strength sufficient to overcome warping of the cover.
