  • Patent number: 10609955
    Abstract: The invention provides a cigarette with a filter element comprising at least one longitudinally extending section of filter material. The section of filter material comprises a smoke-altering material therein that is useful for removing a quantity of vapor phase chemicals from the mainstream smoke. The section of filter material further comprises one or more tubes inserted into and extending through section of filter material. The one or more tubes each define a channel adapted for passage of mainstream smoke through the section of filter material while substantially avoiding contact of the portion of mainstream smoke therein with the smoke-altering material. The provision of a portion of mainstream smoke substantially unaltered by the smoke-altering material can be useful to retain certain desirable taste and other sensory properties of the mainstream smoke.

  • Patent number: 10562656
    Abstract: Methods and machines are provided for forming a five-sided carton of packages of smoking articles. A piece of film material is applied to a plurality of packages of smoking articles such that five sides of the plurality of packages are at least partially covered by the film material, but the sixth side remains uncovered. The film material is applied such that the group of packages is sufficiently tightly bound so that none of the packages may slip free from the carton. The sixth side of the plurality of packages in the carton remains exposed so that tax stamps may be easily applied. The film of material may be applied so that a gap is formed relative to the sixth side.
