ABSTRACT:
A resealable carton, having a product-containing bag liner, is constructed such that the liner bag is positively held in the folded, sealed condition by the incorporation of a fold support ledge which extends inwardly from an end wall of the carton. The bag is held against the support ledge by one of the closure flaps, which creates a tightly constructed U-shaped fold in which the bag is folded around the end of the closure flap. The liner is secured in that position in part by being captured between the top of the inner closure flap and an outer closure flap along a top run of the fold. A bottom fold is held between the support ledge and the inner closure flap. The support ledge may be formed in various ways including folding the end wall, embossing the end wall or forming the ledge by adding a bead of self-adhesive material to the end wall.
