Abstract
A pack (1) for smoking articles such as cigarettes has a sealed enclosure of barrier material, with a resealable access aperture to the enclosure. A cover (7) over that aperture has on all its openable edges a permanently tacky surface overlapping over the barrier material there. The cover has a non-adhesive tab (10) to assist opening. 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.
