Problems solved by technology

Therefore, when smoking, there is a larger difference between the draw resistance of the cigarette when Mars is in the high air permeability area and the draw resistance of the cigarette when Mars is in the low air permeability area. Discomfort
[0006] On the other hand, when increasing the number of low-permeability areas of each self-extinguishing cigarette in order to prevent misfires caused by the cigarette, the overall draw resistance of the cigarette will inevitably increase, and this cigarette cannot provide a comfortable smoking feeling for the smoker.

Embodiment Construction

[0040] figure 1 The filter cigarette includes: a cigarette 2 with low flame spread (low flame spread), a filter 4 adjacent to the base end of the cigarette 2, and a filter paper 7 connecting the cigarette 2 and the filter.

[0041] The cigarette 2 has a filler material 8 and a single wrapping paper 6 wrapping the filler material in a rod shape. The filler 8 includes not only shredded tobacco obtained by cutting tobacco leaves, but also regenerated shredded tobacco obtained by shredding reconstituted tobacco sheets, expanded shredded tobacco obtained by subjecting shredded tobacco to a puffing process, and the like.

[0042] Regarding heat conduction, the cigarette paper 6 has two high-conductivity bands 10 as high-conduction regions, which are arranged apart from each other in the axial direction of the cigarette 2 and surround the cigarette 2 over the entire circumference thereof. Specifically, the first high-conductivity band 10 is positioned at an interval of 20 mm from th...

Abstract

A low ignition propensity cigarette has wrapping paper (6) wrapping filling material into a rod-like shape, and the wrapping paper (6) includes highly conducting bands (10) formed by calendering and arranged in a longitudinal direction of the cigarette, the highly conducting bands (10) having higher thermal conductivity than inherent thermal conductivity of the wrapping paper (6), and burning depression bands (16) formed in the wrapping paper (6) and superposed upon the respective highly conducting bands (10).

Description

technical field [0001] The present invention relates to a low-flammability cigarette capable of reducing the possibility of spreading to combustibles even when the lit cigarette is placed on combustibles, a cigarette paper used for the cigarette, and a method for producing the cigarette paper. Background technique [0002] A self-extinguishing cigarette disclosed in Patent Document 1, for example, is known as one of such low-burning-propagation cigarettes. This cigarette includes a filler and a single cigarette paper wrapping the filler in a rod shape. The cigarette paper includes high air permeability regions and low air permeability regions alternately arranged in the axial direction of the cigarette, and the high air permeability regions and the low air permeability regions have a band shape extending in the circumferential direction of the cigarette. [0003] After the above-mentioned self-extinguishing cigarette is lit, when the smoker does not puff the cigarette and t...
