    摘要: A gable top for a carton formed from a carton blank having an outer layer bonded to an intermediate layer by a first strength and an inner layer bonded to the intermediate layer by a second strength less than by a first strength and wherein the intermediate layer is of an esthetically pleasing color and formed into a gable top by sealing together facing portions of the inner layer so that when the gable top is separated to form a pour spout the inner surface of the pour spout will be aesthetically pleasing.

    摘要: A carton having one or more closure flaps with a delaminating window formed by lines which are not substantially straight in a direction parallel to the fold line separating the flap from the panel of the carton. Preferably, the delaminating window is formed from an undulating curve. The lack of straight lines tends to minimize the risk that bending will occur and interfere with the sealing of the carton. The invention also includes a process of sealing the cartons by adhering the delaminating window to another flap.
