An inner frame provides support to the barrier material adjacent to the aperture, allowing the adhesive cover to be pressed firmly against the barrier layer to aid resealing. The pack may be provided with or without an outer carton. If an outer carton is included, the carton may be of a generally rigid card material, and may have a flip-top configuration, may be a Laube box, or may have a shell-and-slide configuration.An inner frame provides support to the barrier material adjacent to the aperture, allowing the adhesive cover to be pressed firmly against the barrier layer to aid resealing.
