  • Patent number: 6826889
    Abstract: A rigid 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 released by the repositioning of the adhesive layer, carrying with it the flap of barrier material. A machine for assembling the pack is also disclosed.

  • Patent number: 6701935
    Abstract: A method of incorporating fibriform smoke-modifying material in smoking material rod, wherein fibriform smoke-modifying material is fed longitudinally thereof to a rod making machine (1). The longitudinal feed path in the machine is in a travel direction of the smoking material deposition run of the suction band (3) of the machine. The fibriform material (13) is either constrained by guide means (15) in the machine to follow a feed path spaced from the run (31) of the suction band against the suction force towards the run or the feed path of the fibriform smoke-modifying material is caused to ascend toward the deposition run under the influence of the suction force towards the run, until at a predetermined distance along the deposition run the fibriform material becomes supported and is subsequently maintained at a predetermined distance from the run by particulate smoking material (20) deposited on the run. Thereafter further smoking material (20′) is deposited on the deposition run.
