Mouthpiece

Abstract

A non-combustion smoking tool, which uses a real filter cigarette as it is, and which vaporizes nicotine from the tobacco leaves without lighting the product to enable inhalation of the vaporized nicotine, has a problem that a smoker cannot take in 100% of the vaporized nicotine. Thus, a mouthpiece is designed to have an air flow control structure or an air flow control element, or to be combined with a cigarette guide tube, so as to enable the mouthpiece to vary the rate at which the nicotine vaporized from the tobacco leaves is taken in.

Description

TECHNICAL FIELD[0001]The present invention relates to a mouthpiece provided for non-combustion smoking tools and used in combination with a non-combustion smoking tool of Japanese Patent Application 2009-049879 or Japanese Patent Application 2009-293338 made by the present applicant (each hereinafter referred to as “tool—of the earlier application of the present application”), a non-combustion cigarette system disclosed in Japanese Translation of PCT Application 2009-509521 or a pipe-type non-combustion smoking tool.BACKGROUND ART[0002]The “tool of the earlier application of the present application” and the non-combustion smoking tools disclosed in Patent Document 3and Patent Document 4 have been proposed to improve various problems of a normal smoking method to light tobacco leaves for smoking, and are tools which, while using a generally commercially available cigarette or cigar as it is, can vaporize nicotine from the tobacco leaves at a suitable temperature to enable inhalation ...

AI Technical Summary

Benefits of technology

[0015]FIG. 3 shows a cross-sectional view of an example of a mouthpiece used as a mouthpiece having a novel structure adopted in the present invention. In the mouthpiece having the novel structure, an air flow control element is formed between an inhalation inlet and a filter of an inserted filter cigarette. If the air flow control element has no through-hole, air passing through the filter part cannot directly reach the inhalation inlet when a smoker inhales through the mouthpiece. Thus, when the smoker inhales, nicotine vaporized from the tobacco leaves by heating the tobacco leaves goes out of the wrapping paper of the tobacco, and passes through a space formed between an inner wall of a non-combustion smoking tool and the wrapping paper of the tobacco and the filter, and further passes through the air control element so as to be brought to the inhalation inlet. This is advantageous because, due to the air flow containing the nicotine, the nicotine vaporized from the tobacco leaves is prevented from being absorbed by the filter, so that the smoker can inhale most of the nicotine vaporized from the tobacco leaves.

[0016]Further, it is advantageous to form a hole on the filter-contacting surface of the air control element of the mouthpiece having the novel structure adopted in the present invention, because it produces an air flow flowing through the filter, making it possible to allow the filter to absorb an appropriate amount of nicotine vaporized from the tobacco leaves, and thus to allow the smoker to inhale the vaporized nicotine with a desired concentration.

[0017]Further, FIG. 8, FIG. 13 and FIG. 14 show cross-sectional views of other examples of mouthpieces having the novel structure adopted in the present invention, in which each of them has an advantage that the rate at which the filter absorbs the produced nicotine can be controlled between zero and an arbitrary rate.

[0018]Further, the combination of a cigarette guide tube with these mouthpieces having the novel structure is advantageous because it provides easy-to-use mouthpieces with an attached cigarette guide tube.

[0019]Further, in the mouthpiece having the novel structure adopted in the present invention and provided with the attached cigarette guide tube, it is advantageous to bend an end of the cigarette guide tube inward because the mouthpiece with the attached cigarette guide tube can be taken out of the non-combustion smoking tool together with the inserted filter cigarette.

Problems solved by technology

When the tool of the earlier application of the present application and the non-combustion smoking tool proposed in Patent Document 3 were actually used by inserting a filter cigarette therein, the following problems were found.

However, when inhaled through the filter similarly as when normally smoking by lighting them, most of the nicotine vaporized out of the tobacco leaves by heating the tobacco leaves is absorbed by the filter, so that a smoker can inhale only a small amount of nicotine vaporized out of the tobacco leaves.

However, when heated at such a high temperature, the tobacco leaves get burned to add burning smell, thereby not only harming the flavor, but also ending the vaporization of nicotine from the tobacco leaves in a short time.
