First and second ratchet mechanisms (14,19; 20, 24) are disposed between the second body portion (4) and the first and third body portions respectively to allow assured rotation of the second portion to select individual flavorants for the smoke passing to the consumer.Type: GrantFiled: October 15, 2010Date of Patent: July 8, 2014Assignee: Tobacco Research and Development Institute (Proprietary) LimitedInventor: Gerhard Malan Le Roux

Patent number: 8752557Abstract: An aerosol generator device for delivering an aerosol of a nicotine salt is provided. The aerosol generator comprises: (i) a mouth end; (ii) a first chamber containing a porous material wetted with liquid nicotine, (iii) a second chamber containing a porous material wetted with a solution of a volatile acid, (iv) a third chamber in fluid communication with the first and second chambers, leading to the mouth end, and (v) an outer housing defining a passageway for air through said device. A nicotine vapor can be produced by drawing air along the passageway and through the porous material wetted with liquid nicotine. An acid vapor can be produced by passing air along the passageway and through the porous material wetted with a solution of a volatile acid. Then, the nicotine vapor and the acid vapor can be admixed in the third chamber to form an aerosol of a nicotine salt, which can be drawn out through the mouth end.Type: GrantFiled: November 2, 2012Date of Patent: June 17, 2014Assignee: Philip Morris USA Inc.Inventor: Peter Lipowicz

Patent number: 8689805Abstract: An atomizing electronic cigarette has an atomizing core component and a liquid storage component, including an electric heater. The electric heater may have a through hole aligned with a channel passing through the liquid storage component. The cigarette can heat and uniformly vaporize liquid from the liquid storage component, with the user inhaling the vaporized liquid. The vapor generated by the atomizing process may be cooled as it flows through the channel.Type: GrantFiled: March 22, 2012Date of Patent: April 8, 2014Assignee: Fontem Holdings 1 B.V.Inventor: Lik Hon

Publication number: 20140026900Abstract: Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.Type: ApplicationFiled: June 7, 2013Publication date: January 30, 2014Applicant: Philip Morris USA Inc.Inventors: Georgios D.
