By Adding Constituent To Smoke Stream Patents (Class 131/335)
  • Patent number: 4966169
    Abstract: A process for manufacturing cigarettes which imposes reduced health risks to the smokers thereof. According to this process redried cut rag tobacco is directly sprayed with one or more pre-selected alcohols which are capable, when the vapors thereof are inhaled by the smoker, of inhibiting or blocking the selective localization of at least one nitrosamine and/or a metabolite thereof in the smoker's tissues such as those of the epithelial lining of his lungs. An example of such an alcohol is cyclohexanol in an ethyl alcohol solution. After the alcohol solution has been sprayed on the tobacco, preferably as it tumbles in the cooler cylinder of the mechanized cigarette making line, and allowed to dry, the tobacco is made or machined in a conventional manner into the final cigarette, either filtered or unfiltered.

  • Patent number: 4655229
    Abstract: A device for delivering flavor utilizing a flavor carrier in powdered form. A preferred embodiment of the system may resemble a conventional cigarette, and includes an overwrap defining a path of airflow through the device, a chamber containing particulate matter, and a means for entraining the particulate matter in the airflow. The overwrap may be a tube, resembling a conventional cigarette in appearance, feel, and draft. A means for entraining the particulate matter may be an intake flow limiter having a passage therein which causes a thin stream of high-velocity air to impinge upon the particulate matter, entraining it in the airflow. Alternately, the entraining means may be a series of baffles or similar components which produce a turbulent airflow, thus entraining the particulate matter. Output means are also provided for eliminating stoppages and for delivering the airflow, with particulate matter entrained therein, to the user.

  • Patent number: 4532943
    Abstract: A filter cigarette is provided which comprises a tobacco rod which includes a charge of tobacco wrapped in cigarette paper, an integral, axially aligned cylindrical filter plug, and tipping paper. The filter plug is divided into first and second segments with the first segment being rotatable with respect to the second segment. Rotation of the first segment with respect to the second segment, in one embodiment of the invention, serves to vary the air dilution value of the cigarette. In another embodiment, rotation of the first segment with respect to the second segment produces variable resistance-to-draw in the cigarette. Both of the above embodiments can be combined into yet another embodiment to produce a cigarette which maintains a constant resistance-to-draw value as the air dilution value is varied. In yet another embodiment, an encapsulated flavorant is provided which is released responsive to rotation of the first segment with respect to the second segment.
