Assignee:

Brown & Williamson Tobacco Corporation - Louisville KY

International Classification:

A24D 300
A24D 304

US Classification:

131336

Abstract:

A filter for a cigarette includes a generally cylindrical permeable filter rod circumscribed by an air permeable tipping material with a plurality of blind-end channels formed in the filter rod, each of the channels being open at one end to the upstream end of the filter rod and extending therefrom, generally in the longitudinal direction of the filter rod, a predetermined distance less than the length of the filter rod.

Filed:

Jul 28, 1986

Appl. No.:

6/889669

Inventors:

David G. Strubel - Jeffersontown KY
Robert A. Sanford - Prospect KY

Assignee:

Brown & Williamson Tobacco Corporation - Louisville KY

International Classification:

A24B 314

US Classification:

131370

Abstract:

A process for manufacturing reconstituted tobacco from tobacco stems and tobacco fines includes treating the tobacco stems to a fibrous form, and mixing the fibrous tobacco stems with tobacco lamina fines. The mixture is then deposited on a moving mesh screen whereon it is formed into a felt-like mat or sheet of generally uniform thickness. The reconstituted tobacco sheet is then removed from the mesh screen for further processing to produce a tobacco smoking article.

Appl. No.:

6/349232

Inventors:

Robert A. Sanford - Prospect KY
Andrew McMurtrie - Louisville KY

Assignee:

Brown & Williamson Tobacco Corporation - Louisville KY

International Classification:

A24D 304

US Classification:

131336

Abstract:

A filter for a cigarette includes a porous filter rod circumscribed by a non-porous or air impermeable wrapper, and ventilating air grooves embedded in the wrapped filter rod which extend from one end of the filter rod a preselected distance generally longitudinally of the filter rod. An air permeable tipping material circumscribes the wrapped filter rod which provides a path therethrough for ventilating air flow only into the grooves. The walls of each of the grooves defined by the wrapper, in one form of the invention, is permeable to air over virtually its entire length, and in another form of the invention is permeable to air flow only adjacent the mouth end of the filter. Under certain smoking conditions most, if not all of the ventilating air will flow from the grooves into the smoker's mouth through the open end of the grooves at the mouth end of the filter rod. Under certain other smoking conditions, at least a part of the ventilating air will pass through the air permeable walls, or portions thereof, of the grooves and into the filter rod wherein it co-mingles with and dilutes the smoke flowing therethrough.

Assignee:

Brown & Williamson Tobacco Corporation - Louisville KY

International Classification:

A24D 304

US Classification:

131336

Abstract:

A filter for a cigarette includes a porous filter rod circumscribed by a smoke impervious wrapper wherein the filter rod with the smoke impervious wrapper therearound is provided with grooves embedded therein and extending from one end thereof a preselected distance longitudinally therealong. Tipping material circumscribes the smoke impervious wrapper and is provided with flow-through openings therein in flow communication with the grooves. Support means are provided for the tipping material at the mouth end of the filter to maintain the tipping material in circumferential equalization.

Appl. No.:

6/492978

Inventors:

Daniel V. Cantrell - Prospect KY
Robert A. Sanford - Prospect KY

Assignee:

Brown & Williamson Tobacco Corporation - Louisville KY

International Classification:

A24D 304

US Classification:

131336

Abstract:

A ventilated mouthpiece adapted to be attached to a smoking article, such as a cigarette, includes a generally cylindrical core member of smoke and air impermeable material having a smoke inlet end and a mouth end. The smoke inlet end is to be placed in juxtaposition to one end of the tobacco column of the cigarette. The core member is formed with a plurality of smoke flow capillaries therethrough for delivering unfiltered smoke from the tobacco column to the mouth end of the core member, and a plurality of ventilation air flow channels which receive ambient ventilation air and delivers the ventilation air to the mouth end of the core member. The smoke outlets from each of the smoke flow capillaries at the mouth end of the core member are located in close proximity to and are radially situated inwardly of the mouth end of the core member from the air outlets from the air flow channels.

Inventors:

Robert A. Sanford - Prospect KY

Assignee:

Brown & Williamson Tobacco Corporation - Louisville KY

International Classification:

A24D 304

US Classification:

131336

Abstract:

A filter for a cigarette includes a porous filter rod having a capillary smoke passageway extending coaxially therethrough and a hollow, generally cylindrical mouthpiece coaxially located with the filter rod at the mouth end of the filter rod. The filter rod is circumscribed by a non-porous wrapper, and the filter rod with the non-porous wrapper therearound is provided with grooves extending from the mouth end thereof a preselected distance longitudinally therealong. The mouthpiece is formed with air flow channels in flow communication with the grooves of the filter rod, and smoke flow channels in flow communication with that area of the filter rod mouth end between adjacent grooves of the filter rod. Tipping material circumscribes the filter rod and the mouthpiece, and is provided with flow-through openings therein in flow communication with the grooves.
