A packaging carton manufactured from a pre-shaped blank (10), cut from a flexible sheet of foldable material. The carton has a plurality of panels (A, A1, A2, B, B1, B2, C1, C2, D1, D2, E) and naps (32, 33, 36, 37) separated by fold lines (16 to 31) that define edges of the panels. Selected pairs of the end flaps (36, 37) of the carton incorporate between them a foldable gusset (39) subtended by two converging fold lines (40,41) that converge on a selected fold lines (16, 19). Further selected flaps (32, 33) of the carton (40) are provided with slots (34) each of which is dimensioned and positioned for receiving one of the gussets (39). The gussets (39) are positioned relative to the slots (34) so that the gussets (39) engage in, and are retained by, the respective slots (34) thereby to hold adjacent panels of the carton together.
