Cigarettes include a filter element which have a gathered web of paper incorporating a carbonaceous material. The paper is gathered so as to include a plurality of longitudinally extending channels, and the channels provide a cross-sectional void area of about 5 to about 30 percent of the filter element.

Cigarette filter

The present invention generally relates to a smoking article having a fuel element, a physically separate aerosol generating means, a mouthend piece, and improved means for delivering one or more flavorants to the user which comprises a carbon filled sheet material longitudinally disposed behind the aerosol generating means in a non-burning portion of the smoking article which carries or otherwise contains one or more flavorants. More specifically, the present invention is directed to a carbon filled sheet of tobacco employed as at least as a portion of the mouthend piece of such articles to carry flavorants, particularly highly volatile flavorants like menthol.

Smoking article with improved means for delivering flavorants

A smoking article includes a short, combustible, carbonaceous fuel element in a heat exchange relationship with a substrate carrying glycerin, tobacco extract, and a portion of an essential oil gland bearing plant. For example, fragments of cinnamon bark, lovage root, chamomile flowers or cardamon physically separate from the fuel element provide for a controlled release of a flavor profile during use of the smoking article. Heat provided by the burning fuel element acts to release essential oils from the glands to provide a complex flavor and aroma profile. The smoking article is capable of providing the user with many of the pleasures of smoking by heating but not necessarily burning tobacco.
