Abstract

A carton of the wrap-around type has a pair of overlapped base panels. One of the base panels which carries a locking tab overlies a tongue protruding from the end edge of the other base panel. The protruding tongue is formed with a complementary locking aperture engaged by the locking tab to secure the overlapped panels together. On either side of the locking tab, the said one base panel has a hinged tab protruding from the end edge of that panel. Each of the hinged tabs underlies the end edge of the other base panel, one on each side of the protruding tongue. This ‘over and under’ arrangement presents less of an externally overlapped edge than is the case of a simple complete overlap and thus mitigates against the base panels being skewed or prized apart leading to tearing and/or dislodgement of the locking means.
