Various kinds of flavour solutions can be used in the smoking article. The amount of the volatile aromatic components can be controlled easily. Further, it is possible to suppress the loss of the aromatic component during preservation of the smoking article.Type: GrantFiled: March 2, 1992Date of Patent: July 26, 1994Assignee: Japan Tobacco Inc.Inventors: Akimichi Tamaoki, Shizuo Suhara, Morio Kondoh

Patent number: 5275859Abstract: Disclosed are articles, such as smoke filters, which contain fibers that have complex geometry in combination with tobacco smoke modifying agents such as flavorants. The fibers are preferably made of a polyester such as poly(ethylene terephthalate) and preferably are capable of spontaneously transporting water or n-decane on their surfaces. The articles of the invention result in improved delivery of the tobacco smoke modifying agent to the user.Type: GrantFiled: December 21, 1992Date of Patent: January 4, 1994Assignee: Eastman Kodak CompanyInventors: Bobby M.

Patent number: 5269329Abstract: There is disclosed a method of adding flavorant to cigarette filters. A cigarette filter is made by forming a filter web using non-woven web comprising thermoplastic meltblown fibers of filaments that are present as fused agglomerates in a number fraction exceeding 33 percent and wherein a majority of fiber crossings of agglomerates are weld points; adding tobacco extracts to the filter web such that the filter web contains between 10% and 110% tobacco extracts by weight of the filter web; adding glycerin or a glycerin-water mixture to the thus treated filter web; and forming the thus treated filter web into a rod.Type: GrantFiled: July 9, 1990Date of Patent: December 14, 1993Assignee: Kimberly-Clark CorporationInventors: Robert G. Geer, Thomas L. Fillio, Loyd G. Kasbo

Patent number: 5261425Abstract: A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by two layers of paper wrapping materials. The first or inner wrapping material includes an inorganic filler material and tobacco material within the web. The inner wrapping material also can include a water soluble salt burn chemical and a carbonaceous material within the web. The second or outer wrapping material circumscribes and overwraps the first wrapping material, has a cellulosic base web and inorganic filler material, and exhibits a low inherent air permeability. The outer wrapping material can include a magnesium hydroxide filler, and exhibits an inherent air permeability of below about 15 CORESTA units and a net air permeability above about 40 CORESTA units. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.Type: GrantFiled: February 27, 1991Date of Patent: November 16, 1993Assignee: R. J. Reynolds Tobacco CompanyInventors: Mark L. Raker, Barbara W. Arzonico, Patricia F. Perfetti, Thomas L. Gentry, Cynthia L. Davis
