Abstract: A universal blank adapted for assembly as a carton by either a top/end load cartoner or locking tab cartoner, and related method of assembly. The universal blank includes one or more minor flaps forming locking tabs and one or more major flaps forming locking slots. The locking tab/slots facilitate assembly with a locking tab cartoner. Alternatively, the universal blank can be processed by a top/end load cartoner by first bonding two of the outer minor panels. Graphics formed on the universal blank present a desired, aesthetically pleasing appearance upon assembly by either cartoning technique. Further, preferred gluing techniques can be employed to promote consistent assembly by a top/end load cartoner.
