Non-heating tobacco flavor suction device

摘要

A non-heating tobacco flavor suction device (1) comprises a suction holder (2) with a suction path defined inside and a filler (8) arranged in the suction path. The filler (8) is formed of tobacco particles. The suction path and the filler (8) arranged therein provide a ventilation resistance of between about 40 and about 80 mmAq in cooperation with each other.

1. A non-heating tobacco flavor suction device, comprising:
a hollow, cylindrical suction holder made of a synthetic resin and having an open distal end, an open proximal end and a suction path defined therebetween, the suction path including a main passage extending from the distal end to the proximal end, the proximal end serving as a tapered mouth end, and a filler contained in the main passage of said suction holder, said filler, including tobacco particles made from tobacco materials, potassium carbonate and a hydrogen carbonate, without compressing the tobacco particles, to give in the absence of heating, a flavor derived from the tobacco materials to the air inhaled by a user through the mouth end, wherein the tobacco particles have a particle size of between 0.212 and 2.0 mm and wherein a filling amount of the tobacco particles in said filler is set such that said filler exhibits the following features (i) and (ii): (i) said filler provides an initial ventilation resistance before said tobacco flavor suction device is first sucked, and provides a terminal ventilation resistance greater than the initial ventilation resistance after said tobacco flavor suction device is repeatedly sucked, said terminal ventilation resistance being the ventilation resistance observed after 100 puffs of the tobacco flavor suction device; and (ii) the initial and terminal ventilation resistances are each within a range of between about 40 mmAq and about 80 mmAq, and the difference between the initial and terminal ventilation resistances is smaller than 20 mmAq.
