Abstract:
A smoking article (20) has a pattern (34a, 34b, 34c, 34d, 36d' ) of permeability reducing film forming compound applied to the wrapping paper (24). The pattern is configured so that when a smoking article is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film forming compound located only on sides of the smoking article not in contact with the substrate. At these longitudinal locations, the restricted airflow to the tobacco due to the presence of the substrate, in combination with the film-forming compound located at the sides is sufficient to cause the smoking article to self -extinguish. However, when the smoking article is held by a smoker, the presence of the film-forming compound does not necessarily by itself cause the smoking article to extinguish. A desirable self burn capability is therefore maintained.
Abstract:
A process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) freeze-drying a solution of a biopolymer to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby prepare a filter plug for a smoking article. Another process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) extruding a mixture of a foaming agent and a biopolymer comprising a protein to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby form a filter plug for a smoking article. A cigarette is also disclosed comprising a tobacco rod and a filter attached to the tobacco rod, wherein the filter comprises a filter plug prepared according to the process of the invention and the structure obtained in the extruding has an average pore size ranging from about 0.04 mm to about 0.20 mm.
Abstract:
Disclosed is a copolymer that includes a repeat unit containing a flavorant -containing pendant and a salt-containing repeating unit. In addition, a comestible, a smoking composition, a smoking article, a smokeless tobacco composition and a heatable or combustible product are provided which incorporate one or more of the flavorant-containing copolymer.
Abstract:
Delivery of additives in a smoking article (200) is provided through thermally degradable, robust immobilized additive inserts (100). Additives can be immobilized in an elongated device (110) or an insert, wherein the elongated device (110) or the insert is sufficiently robust to allow the elongated device (110) or the insert to be manually or machine inserted into a smoking article (200) while maintaining the structure of the elongated device (110) or the insert. By providing additives in the form of thermally degradable immobilized additive inserts (100), migration and/or loss of the additives in a smoking article (200) prior to smoking can be reduced.

Abstract:
Compositions are provided which contain immobilized flavorants, in the form of supramolecular complexes of flavorant compounds, for flavor delivery. One embodiment relates to the flavorant supramolecular complexes themselves. Other embodiments relate compositions which contain the flavorant supramolecular complexes and a substrate. In particular embodiments, the substrate is smokeable, but in other embodiments may be non- smokeable or comestible.
Abstract:
A wrapper 123 for cigarette manufacture includes one or more transversely extending band regions 126 applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate. Any suitable printing technique can be used to apply the aqueous solution to the banded regions. The pattern of banded regions may be bands, stripes, two-dimensional arrays, undulated regions, and the like along and/or around the tobacco rod. The pattern can be applied in one or more layers. The pattern may be configured so that when a smoking article is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film-forming compound located only on sides of the smoking article not in contact with the substrate. The invention also encompasses a smoking article 120 including such a wrapper around a column of tobacco to form a tobacco rod 122. A method of providing a smoking article having an ignition propensity not greater than 25% is also disclosed.
Abstract:
A cigarette (10) includes cigarette paper (12) comprising a base web (16) and at least one banded region (14) comprising iron oxide nanoparticles. The at least one banded region has a porosity less than the porosity of the base web such that the at least one banded region exhibits a slower burn rate compared to adjacent non-banded regions.
