Smoking article with tobacco beads

摘要

A component of a smoking article having tobacco beads. The tobacco beads can be located in a filter and/or a tobacco rod. The filter can be a multi-component filter, wherein an sorbent (preferably upstream) removes at least one constituent from mainstream tobacco smoke passing through the filter and downstream tobacco beads compensates for taste lost to the sorbent. The tobacco beads optionally include flavorants in addition to tobacco particulates. The tobacco beads can be located within a cavity in the filter or within the tow. This component can comprise additional flavors, which are released into the mainstream smoke under ambient conditions. The tobacco beads optionally include binders such as microcrystalline cellulose or other cellulosic material, which can be formed into a paste with tobacco powder and optionally with additional flavors. The paste can be extruded and spheronized to form the tobacco beads.

1. A smoking article comprising:
a tobacco rod; and a filter, the filter comprising an activated carbon sorbent at an upstream location along the filter and at least one tobacco bead at a downstream location along the filter, each tobacco bead consisting essentially of:
(a) tobacco lamina particles;(b) water;(c) one or more flavorants; and(d) microcrystalline cellulose, wherein the tobacco bead has a moisture content of about 8% to about 25% of a total weight of the tobacco bead, wherein the tobacco bead is in a condition of having been extruded, rounded and vacuum dried to said moisture content, wherein the one or more flavorants comprises menthol, wherein the one or more flavorants are trapped within the tobacco beads so as to minimize migration or evaporation of the one or more flavorants during storage, and wherein the one or more flavorants are released in the absence of cigarette coal heat to enhance tobacco character and reduce carbon off-taste.
