ABSTRACT:
A unitary wrapper blank having top, bottom and side walls interconnected to form a tubular structure about a plurality of articles incorporates one composite wall formed of a pair of overlapping panels one of which incorporates at least one specially configured locking slit which receives a specially configured locking tab struck from the other lap panel after the locking tab is folded out of the plane of the other panel along a hinge line and into flat face contacting relation with an adjacent positioning tab formed on an edge of the other panel which tab also is inserted along with the locking tab into the locking slit. After the positioning tab and locking tab are fully inserted into the locking slit, the locking tab swings away from the positioning tab due to its inherent bias which tends to swing the locking tab into the plane of the panel from which it is struck.
