发明名称 PACKAGING OF SMOKING ARTICLES
摘要 A rigid pack of smoking articles is made to have improved shelf life and to be resealable. A barrier material is sealed around the rigid pack. The rigid pack has a potential or actual access aperture extending from a top face into a major face. The barrier material has a line of severance or weakening defining a flap, which is in register with the potential or actual access aperture. Over the flap is a layer which overlaps it on each severable side with a portion having permanently-tacky adhesive. A non-adhered pull tab is preferably provided on the layer. To open the pack the user lifts the flap and if necessary the access aperture. After removal of a smoking article the gap in the barrier layer is reclosed and resealed by the repositioning of the adhesive layer, carrying with it the flap of barrier material. A machine for assembling the pack is also disclosed.
