Patent number: 8807144Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a wrapper comprising cellulosic fibers and a filler. In accordance with the present disclosure, the filler has a particle size of at least about 3.2 microns and is present in the wrapper in an amount less than about 20% by weight. Further, the wrapper may have a basis weight of less than about 23 gsm and a permeability of from about 15 Coresta to about 110 Coresta. It has been discovered that such wrappers are capable of reducing the ignition proclivity characteristics of a smoking article. If desired, the particular wrapper as described above can also contain discrete areas treated with an ignition reducing composition which further serves to reduce the ignition proclivity characteristics of the article.Type: GrantFiled: February 21, 2008Date of Patent: August 19, 2014Assignee: Schweitzer-Mauduit International, Inc.Inventors: Vladimir Hampl, Jr., Alice Gu, James Rossi-Espagnet

Treated areas on a wrapper for reducing the ignition proclivity characteristics of a smoking article
Patent number: 8646464Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a paper wrapper containing cellulosic fibers and filler particles. The paper wrappers are formed so that the filler particles form a concentration gradient throughout the thickness of the wrapper. More particularly, a greater concentration of filler particles are present at a first surface in comparison to the amount of filler particles present at the opposite surface. In accordance with the present disclosure, an ignition reducing composition is applied to the first surface. In this manner, treated areas having more uniform properties are formed.Type: GrantFiled: February 5, 2009Date of Patent: February 11, 2014Assignee: Schweitzer-Mauduit International, Inc.Inventors: Vladimir Hampl, Jr., James C.

Patent number: 6584981Abstract: The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself. Specifically, it has been unexpectedly discovered that the ash cohesiveness of a paper wrapper is noticeably improved when carbon fibers having an average length less than about 0.75 inches are incorporated into the paper in an amount up to about 60% by weight. Paper wrappers made with carbon fibers in accordance with the present invention have superior ash characteristics in comparison to paper wrappers incorporating only flax or other cellulosic fibers. Further, the ash cohesiveness of the paper is improved without resulting in the decline in the quality of other ash characteristics.Type: GrantFiled: November 13, 2001Date of Patent: July 1, 2003Assignee: Schweitzer-Mauduit International, Inc.Inventor: Vladimir Hampl, Jr.

Publication number: 20010032653Abstract: The present invention is generally directed to high opacity cigarette wrapping papers. The wrapping paper made according to the present invention contains a mixture of a white pigment and a black pigment. The white pigment, which can be, for instance, calcium carbonate, has a median particle size of from about 0.1 microns to about 0.5 microns, and particularly from about 0.2 microns to about 0.4 microns. It has been discovered that this particular particle size range, which is equal to one-half the wavelength of visible light, greatly increases the opacity, brightness and whiteness of the paper. Small amounts of a black pigment, such as carbon, are then added to further increase the opacity without significantly decreasing the whiteness or brightness of the paper relative to conventional cigarette paper.Type: ApplicationFiled: April 12, 1999Publication date: October 25, 2001Inventor: VLADIMIR HAMPL

Patent number: 6305382Abstract: The present invention is generally directed to low weight cigarette wrapping papers. In particular, the wrapping papers, although having a low basis weight, have an opacity of at least 70% and a tensile strength comparable with conventional papers. Wrapping papers made according to the present invention contain a white pigment having a medium particle size of from 0.1 microns to about 0.5 microns. In one embodiment, a black pigment can also be combined with the white pigment in small amounts.Type: GrantFiled: October 19, 1999Date of Patent: October 23, 2001Assignee: Schweitzer-Mauduit International, Inc.Inventor: Vladimir Hampl, Jr.

Patent number: 6298860Abstract: The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself. Specifically, it has been discovered that the ash characteristics of a paper wrapper are noticeably improved when the paper is treated with a carboxylic acid salt solution having a pH of from about 5.5 to about 8.0. The carboxylic acid salt solution can be for instance, an aqueous solution containing a metal succinate or a metal citrate.Type: GrantFiled: September 15, 1999Date of Patent: October 9, 2001Assignee: Schweitzer-Mauduit International, Inc.Inventors: Vladimir Hampl, Jr., Kerry Mahone
