It should noted that a cigarette available on the market provides six to ten puffs under the standard smoking condition (ISO), while such a cigarette having a short cut tobacco rod provides puffs considerably smaller than that provided by the cigarette available on the market, which fails to satisfy smokers.
However, the cigarette having a cut tobacco density not lower than 300 mg/cc is not adapted for high-speed production.
As a result, it has been found that, in the case of combining materials used for manufacturing ordinary cigarettes and employing a standard cut tobacco density, the number of puffs provided by the cigarette is decreased if the length of cut tobacco rod is short, resulting in failure to satisfy smokers.
It has been found th

Embodiment Construction

represent cigarettes of the present invention. To be more specific, in the cigarettes of Examples 1 to 3, the cigarette wrapper has a basis weight of 17 to 21 g / m.sup.2, the mixing ratio of the calcium carbonate filler of 16 to 25% by weight and the calcium carbonate content of 3 g / m.sup.2 or more, and the tobacco section has a rod length of 30 to 46 mm.

[0026] Table 2 shows the results of measurements of the air permeation resistance, the spontaneous combustion rate, the burned length, the spontaneous combustion time, the tar content in the mainstream smoke, the amount of the sidestream smoke, and the number of puffs in respect of each of the cigarettes that were tested. The combustion state of the cigarette was measured under the standard smoking condition (ISO).

Abstract

A cigarette has a tobacco section in which cut tobacco is wrapped with a cigarette wrapper, a filter section connected to one end of the tobacco section, and a tip paper integrally connecting the tobacco section to the filter section in a manner to cover the proximal end portion of the tobacco section and the filter section and provided with ventilation holes formed in a circumferential direction in positions apart from the smoking end of the filter section. The tobacco section has a rod length of 30 to 46 mm, and a cut tobacco filling density of 180 to 270 mg/cm3. The cigarette wrapper has a basis weight of 17 to 21 g/m2, a mixing ratio of a calcium carbonate filler of 16 to 25% by weight, and a calcium carbonate content of 3 g/m2 or more. The cigarette provides at least six puffs under a standard smoking condition.

Description

[0001] This is a Continuation Application of PCT Application No. PCT / JP00 / 09194, filed Dec. 25, 2000, which was not published under PCT Article 21(2) in English.[0002] This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 11-371797, filed Dec. 27, 1999, the entire contents of which are incorporated herein by reference.[0003] 1. Field of the Invention[0004] The present invention relates to a cigarette that permits at least six puffs in spite of its short rod length of tobacco section.[0005] 2. Description of the Related Art[0006] In order to prevent a fire and to suppress sidestream smoke or to prevent carbon dioxide gas generation, a cigarette is proposed having a cut tobacco rod with a short length. For example, Japanese Utility Model No. 3049857 discloses a cigarette the length of which cut tobacco rod is half that of the ordinary cigarette in order to lower the amount of carbon dioxide generated per cigarette. Also Jpn. P...
