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 flaps 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. |
