Abstract: A unitary package comprising a plurality of individual inner packages juxtaposed with each other at one or more interfaces. At least some inner packages are wrapped in a wrapper and are peripherally disposed along at least first and second outside walls of the unitary package, defining these first and second outside walls. A first sheet of material having at least one line of weakness is juxtaposed with the first outside wall and interconnects all peripherally disposed inner packages by engaging each of them. Preferably, a second sheet of material is juxtaposed with the second outside wall interconnecting all peripherally disposed inner packages. Preferably, both sheets of material have a self-registering pattern of a plurality of lines of weakness running in both mutually perpendicular directions and comparatively closely spaced such that there is a high probability that at least one of these lines is positioned at the interface of the individual inner packages.
