The smokeless tobacco of the present invention comprises: a tubular main body having airtightness; a fiber layer for holding a tobacco flavoring solution in a central portion of the main body; It comprises an intake section having an air inflow hole, and a suction section having an outflow prevention means and an air outflow hole.

And the biggest feature of the smokeless tobacco of the present invention is that it has an air flow passage between the main body and the fiber layer, and the air inflow hole, the air flow passage, and the air outflow hole communicate with each other. The cigarette flavor solution vaporized from the fiber layer into the air flow passage can be suctioned from the suction port and tasted.

An embodiment of the smokeless tobacco of the present invention will be described with reference to the drawings for easy understanding. The present invention is not limited to the embodiments described below.

FIG. 1 is a schematic sectional view for explaining the structure of the smokeless tobacco of the present invention. As shown in FIG. 1, the smokeless tobacco of the present invention comprises a cylindrical main body 1 made of an airtight material, a fiber layer 2, a lid portion 3 corresponding to an air intake portion, and a suction portion 4 connected to each other. Or it is connected and configured. Then, for example, a felt-like fiber layer 2 is inserted into the center of the main body 1.

First, the main body 1 will be described.

FIG. 2 is a cross-sectional view taken along the line II-II in FIG. As shown in FIG. 2, a plurality of ribs 1a are provided on the inner surface of the main body 1 in the longitudinal direction, and an air flow passage 1b is formed between the ribs 1a.

The fiber layer 2 holding the tobacco flavor solution is inserted and held in the center of the main body 1 which is a space surrounded by the tops of the ribs 1a. The size of the rib 1 a in the radial direction of the main body 1, that is, the height of the top of the rib 1 a is not particularly limited, and the air flow passage can be retained when the fiber layer 2 is expanded by being impregnated with the tobacco flavoring solution. Any value within the range is acceptable.

Also, the number of ribs 1a is not particularly limited, but the fiber layer 2 Any number can be used as long as it can be securely fixed and can form an air flow passage for transporting the vaporized tobacco flavor solution to the suction port 4. It is preferable to provide at least a plurality of ribs.

Therefore, the rib la does not necessarily need to be provided from one end to the other in the longitudinal direction of the main body 1 as long as an air flow passage that carries the vaporized tobacco flavor solution to the mouth portion 4 can be formed.

Here, when the rib 1a is not provided, a spacer having an air flow passage can be arranged between the main body 1 and the fiber layer 2. For example, a spacer in which hollow cylinders are connected can be used.

Further, it is also possible to form an air flow passage by changing the shape of the fiber layer 2. For example, if the surface of the fiber layer 2 which is in contact with the main body 1 is made uneven or polygonal, an air flow passage can be formed between the fiber layer 2 and the smooth inner surface of the main body 1.

The main body 1 is cylindrical in FIG. 1, but may have any cross-sectional shape as long as it is cylindrical.

The main body 1, the lid 3 and the mouth 4 may be made of an air-tight material so that the tobacco fragrance solution does not seep out.For example, synthetic resin, wood, metal, ceramic, etc. are used. Can be manufactured. Above all, it is preferable that the main body 1 be made of synthetic resin because it can be integrally molded with the rib 1a and the production efficiency is excellent.

The synthetic resin that can be used here may be any resin that can be molded and has airtightness and excellent strength after molding, and examples thereof include thermoplastic resins such as ABS resin and polypropylene.

When the lid 3 and / or the suction port 4 are to be fitted, the lids 3 and Z or the suction port 4 may be made of, for example, polyethylene or the like so as to be easily connected to the main body 1 to form a sealed state. Be made of a material having Both are possible.

Next, the fiber layer 2 is arranged at the center of the main body 1 and holds the tobacco flavor solution.

It is necessary that the fiber layer 2 can hold the tobacco flavoring solution and has a function of allowing the tobacco flavoring solution to evaporate and be released. Accordingly, examples of the material constituting the fiber layer 2 include raw materials such as wood pulp and cellulose, natural fibers such as wool, semi-synthetic fibers such as acetate, and chemical fibers such as polyester and acryl-based fibers. Can be

In addition, as long as water retention can be exhibited by the water retention agent described later, the water retention of the material constituting the fiber layer 2 itself may be slightly inferior.

The fiber layer 2 can be produced, for example, by using a woven or non-woven fabric made of these fibers. In particular, from the viewpoint of water retention, it is preferable to use the fibers processed into a felt shape.

In addition, a water-retaining agent harmless to the human body may be mixed with the fiber layer 2 in order to improve water retention. In particular, from the viewpoint of more reliably preventing the tobacco flavor solution from being released as a liquid as it is to the outside or entering the mouth, it is sufficient to apply the solution to at least both ends of the fiber layer 2.

Examples of such a water retention agent include polyacrylic acid such as sodium polyacrylate, and poly (N-vinylacetamide). In the smokeless tobacco of the present invention, a tobacco flavoring solution can be injected into the fiber layer 2 from outside, and the fiber layer 2 itself can be replaced.

Further, the fiber layer 2 containing the tobacco flavor solution may be inserted into the main body 1 when the user wants to taste the tobacco. Therefore, it is preferable that a thread for pulling out is fixed to the end of the fiber layer 2 on the side of the lid 3.

In addition, the fiber layer 2 can be expanded by containing the tobacco flavoring solution. Therefore, it fits more securely inside the main body 1.

The lid 3 and the mouth 4 will be described.

As shown in FIG. 1, the lid 3 has a liquid reservoir 3a, a cylindrical body 3c, and an air inlet 3b which constitute an outflow preventing means, and the suction port 4 constitutes an outflow preventing means. It has a liquid reservoir 4a, a cylindrical body 4c, and an air outlet 4b.

The outflow prevention means composed of the liquid reservoir and the cylinder is provided with an air outlet 4b together with the vaporized tobacco perfume solution when the tobacco perfume solution held in the fiber layer 2 exudes from the fiber layer 2. This prevents the air from being sucked into the mouth and leaking from the air inlet 3b.

That is, in the smokeless tobacco of the present invention shown in FIG. 1, the air inlet 3b and the air outlet 4b of the lid 3 and the mouth 4 are extended toward the inner part of the main body 1, respectively. c and 4c are formed, and the liquid reservoirs 3a and 4a together constitute outflow prevention means.

The lid portion 3 and the mouth portion 4 are preferably detachable from the main body 1 from the viewpoints of injection of the tobacco flavor solution into the smokeless tobacco of the present invention, replacement of the fiber layer, and ease of maintenance. As the attachment / detachment mechanism, for example, a press-fit type, a fitting type, an opening / closing type, a screw-in type, and the like can be adopted. Of course, either one of the lid 3 and the mouth 4 may be removable, or both may be removable.

Here, FIG. 3 shows a cross-sectional view taken along the line III-III 'in FIG.

As shown in FIG. 3, preferably, a rib 4 d is provided around the air outflow hole 4 b in the suction part 4, and a rib 1 a of the main body 1 (see FIG. 1) is provided on the top. The position of the rib 4d can be raised, and the end of the fiber layer 2 inserted into the main body 1 on the side of the suction port 4 can be held down and fixed by these ribs 4d. The number of ribs 4d is not particularly limited. Rib at 1 1a It is not necessarily the same as the number of. Also, from the viewpoint of preventing excessive liquid accumulation, ribs 4 d may be provided in a smaller number than the number of ribs 1 a in the main body 1.

Note that the lid 3 can be provided with the same ribs as the suction port 4.

Next, the tobacco flavor solution held in the fiber layer 2 will be described. Since the smokeless tobacco according to the present invention is a product obtained by vaporizing the tobacco solution flavor, it is necessary that at least the tobacco component can be vaporized.

Therefore, the tobacco perfume solution of the present invention comprises at least a tobacco dry perfume and alcohol.

Among them, it is preferable to use those that are adjusted to pH 7.2 to pH 9.4. This is because it can promote the vaporization of tobacco components such as amines, especially nicotine. Since nicotine is a component that greatly affects the physiological satisfaction of tobacco, pH has an important meaning in the present invention.

The dry tobacco flavor can be produced as follows. First, tobacco leaves are pulverized with a pulverizer, placed in a carbonization kettle, and heated under air ventilation for carbonization. Then, when the outflow of the crude tar is completed, the heating is stopped, and the water contained in the effluent is removed, dried and solidified, thereby obtaining the desired tobacco dry distillation flavor.

The content of the dry tobacco flavor in the tobacco flavor solution may be appropriately adjusted as needed. For example, the amount excluding the solvent may be set to 20 to 5 Omg for one fiber layer.

The tobacco perfume solution in the present invention is prepared by dissolving the above-mentioned tobacco dry distilled flavor in a suitable solvent. In the present invention, the cigarette flavor solution In order to promote the vaporization of alcohol, at least an alcohol such as ethyl alcohol is used as the solvent. In addition, for example, water, glycerin, vitamin E, and the like can be mixed and used.

Examples of the pH adjusting agent for adjusting the tobacco flavor solution to the above pH value include, for example, chitoic acid, malic acid, citric acid, tartaric acid, ascorbic acid, phosphoric acid and their sodium, potassium, and sodium hydroxide. And sodium hydrogen carbonate. In addition, crude sugar, honey, or the like may be used to adjust the taste (sweetness) when pH is adjusted.

Although the size of the smokeless tobacco of the present invention is not particularly limited, it is preferable that the size be in the following range in order to play a role as a substitute for a conventional tobacco and to provide portability.

That is, the smokeless tobacco of the present invention preferably has an outer diameter of 7 to 15 mm and a length of 50 to L50 mm.

In addition, the smokeless tobacco of the present invention is cylindrical in FIG. 1, but is not limited to this. For example, when applied to a Madros pipe, the structure of the main body 1 shown in Fig. 1 can be adopted for the structure of the pipe bowl. In this case, for example, it is preferable that the outer diameter is 15 to 45 mm and the length is 15 to 40 mm.

Further, even in the case of the Madros pipe, even if ribs are not provided on the main body, an air flow passage is formed between the main body and the fiber layer, and a space for providing an air flow passage between the fiber layer and the main body is provided. One circle may be arranged. Further, the surface of the fiber layer in contact with the main body may be made uneven or polygonal. Industrial applicability

As described above, the smokeless tobacco of the present invention can be enjoyed by vaporizing tobacco components from a tobacco flavoring solution and inhaling it. Therefore. No smoke is generated and the problem of sidestream smoke is completely resolved.

Since the main body is airtight, it can maintain its quality until the time of its taste, and can be vaporized and tasted with extremely easy operation.

In addition, since the fiber layer can be replaced or the tobacco flavoring solution can be repeatedly injected, problems such as tobacco disposal and the like can be solved.
