Abstract: Aspects of the disclosure relate to a panel interlocking device, a carton, and a blank for forming the carton. The carton blank incorporating a panel interlocking device for securing together a first and a second panel in overlapping relationship. The panel interlocking device comprises a locking tab struck from the first panel, and a retaining tab defining a locking aperture struck from the second panel. In use the retaining tab is displaced out of the plane of the second panel to receive said locking tab through the locking aperture to be engaged therewith. The retaining tab has opposing side edges each concavely curved as viewed from the outside of the retaining tab.

Abstract: A carton (90) for packaging articles comprises top (14) and bottom (18, 20) panels connected together by spaced side walls (12, 16) to form a tubular structure, and a set of end panels (22a, 22b, 22c, 22d) at each end of the tubular structure. Each set of end panels comprises a pair of lower end closure panels (26a, 26b) connected to the side walls respectively. Each lower end closure panel is hingedly interconnected by gusset panel (34a, 34b) to an anchoring panel (24a, 24b) hinged to an adjacent one of the side wall panels. Each anchoring panel extends into the tubular structure and tucked between the adjacent side wall panel and an adjacent article. One of the gusset panels (34a, 34b) is hinged to the adjacent side wall panel (12, 16) by a hinge line (27a, 27b).

Abstract: A carton (1) comprising a plurality of panels for forming a base panel (12), first and second side walls (14, 24) and first and second top panels (16, 22) coupled to one another by first and second handle panels (18, 20) wherein the first and second handle panels are in substantial face contacting relationship such that the first and second top panels form a top wall of the carton and wherein a reinforcing panel (34a, 34b) is provided in face contacting relationship with both the first and second top panels such that the reinforcing panel forms a bridge connecting between the first and second top panels whereby a portion of each of the first and second top panels is at least two-ply in structure.
