A carton has a wall including overlapping portions of an outside panel and an inside panel. The outside panel includes an outside handle flap defined by an outside severance line while the inside panel includes an inside handle flap defined by an inside severance line. At least a portion of the outside severance line is in substantial registry with at least a portion of the inside severance line where the outside panel overlaps the inside panel. The inside handle flap includes a relief severance line extending from the inside severance line such that the relief severance line divides the inside handle flap into a delamination section and the other section. The relief severance line is configured to initiate delamination of at least the delamination section of the inside handle flap. The structure is at least partially detachable from the carton along the outside and inside severance lines.
