JPH0546297U - Cigarette filter - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a tobacco filter capable of almost completely removing nicotine, tar components and the like contained in a smoking stream of tobacco, and not impairing the flavor and taste associated with smoking. [Structure] A filter material is impregnated with chitin or chitosan, and is further impregnated with the flavor and taste of tobacco.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cigarette filter.

[0002]

[Prior Art]

 As a means for removing nicotine, tar, etc. contained in the smoking stream of cigarettes, a filter made of a bundle of cellulose fibers such as triacetyl cellulose and rayon has been conventionally used. However, the tobacco filter made of such cellulose fibers is not sufficiently satisfactory in the ability to remove nicotine and tar, and further improvement has been desired.

On the other hand, if nicotine, tar components, etc. are almost completely removed from the smoking stream of cigarettes, there arises a problem that the original flavor and taste of tobacco are lost.

[0004]

[Problems to be solved by the device]

 In view of such a situation as described above, the present invention can almost completely remove nicotine and tar components contained in the smoking flow of cigarettes and does not impair the flavor and taste associated with smoking. Is intended to be provided.

[0005]

[Means for Solving the Problems]

 The cigarette filter of the present invention which achieves such an object is characterized in that the filter material is impregnated with chitin or chitosan, and the filter material is impregnated with chitin or chitosan and the aroma of tobacco. It is characterized by

[0006]

【Example】

 Embodiments of the present invention will be described below. Chitin in the present invention is a natural high molecule obtained by treating the outer shells of crustaceans such as crabs, shrimps, and krill and insects with chemicals to separate and purify proteins and calcium components. Deacetylated is chitosan.

Further, as the filter material 1 in the present invention, a cellulose fiber bundle conventionally used as a filter for tobacco such as triacetyl cellulose or rayon, or a material such as pulp or activated carbon is used. It is formed into a cylindrical shape having a diameter and a length, and is integrally attached to the mouthpiece of a cigarette, or is used by being placed inside a pipe.

Then, the filter material 1 is impregnated with chitin or chitosan. When the filter material 1 is impregnated with chitin or chitosan, chitin or chitosan is added dropwise to the filter material 1 formed in advance in a cylindrical shape for diffusion impregnation, or chitin or chitosan is added to the filter material before being formed into a cylindrical shape. To spray and impregnate.

[0009] Furthermore, the filter material 1 impregnated with chitin or chitosan is added with a so-called tobacco flavor for imparting a flavor peculiar to tobacco, and a flavor and taste comprising various flavors such as peppermint. In this case as well, the flavor and taste is added dropwise to the filter material 1 formed in advance in a cylindrical shape for diffusion impregnation, or the flavor and flavor is sprayed and impregnated into the filter material before being formed into a cylindrical shape.

Next, Table 1 below shows the test results of the tobacco filter in which the filter material 1 is impregnated with chitin or chitosan.

[Table 1]

The comparative example in Table 1 above is based on a conventionally used cellulose fiber bundle, and the one in which the cellulose fiber bundle is impregnated with chitin is referred to as Example 1 and impregnated with chitosan. Example 2 was used. The delivery in Table 1 above refers to the absolute value (amount) that passes through the cigarette filter during smoking inhalation.

[0012]

[Effect of the Invention] As is clear from Table 1 above, the cigarette filter of the present invention has a significantly higher filtration rate (adsorption performance) for nicotine and tar than the ordinary cellulose fiber cigarette filter. Especially, the filtration rate of nicotine reaches about twice, and it is possible to almost completely remove the nicotine and tar components contained in the cigarette smoke flow.

Moreover, according to the cigarette filter of claim 2 of the present invention, not only the nicotine and tar components contained in the smoking stream of the cigarette are removed, but also the nicotine and tar components are removed. Tobacco that has become poor in palatability can be given the flavor and taste associated with smoking, and the palatability of smoking is not impaired.
