Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to snuff tobacco, and more specifically, it does not cause discomfort or adverse effects on the surroundings such as smoke, odor, or ash, and it does not cause smoke, odor, or ash to the smoker. The aim is to provide snuff that does not harm health.

(Prior art and its problems) Cigarettes have been consumed in large quantities since ancient times, but there is a problem in that the smoke, odor, ash, etc., give discomfort to people around who do not like cigarettes. Also, because fire is always used, it is one of the causes of fires. Furthermore, there is a problem in that smokers' health is harmed by inhalation of carbon monoxide and tar produced by burning cigarettes.

As a way to eliminate the above-mentioned harmful effects of cigarettes and to meet the demands of tobacco enthusiasts, tobacco cigarettes have been known as a type of snuff tobacco. Since it does not contain any smoke, it does not have a smoky feel, so it was not very popular.

On the other hand, alternative cigarettes (e.g. , American-made product name Flavour) is also known.

This substitute cigarette does not need to be ignited and does not emit smoke, so it eliminates most of the negative effects of conventional cigarettes and gives a smoking sensation that is quite similar to that of conventional cigarettes. It lacked other trace components and aroma of cigarettes, and was not a sufficient substitute for conventional cigarettes.

Therefore, there is a need for a snuff cigarette that does not require ignition, does not emit smoke or ash, and provides the same stimulating or sedative effects as conventional cigarettes.

(Means for Solving the Problems) The present inventor completed the present invention as a result of intensive research in order to meet the demands of the prior art as described above.

That is, the present invention is a snuff cigarette characterized by comprising a cigarette molded article that is air-permeably bound by a resin binder and contains nicotine, and an exterior material that surrounds the molded article.

(Function) By binding chopped tobacco leaves (tobacco powder) with a resin binder to make them breathable and impregnating them with nicotine, and wrapping them in a cigarette-like exterior material, it is possible to smoke without igniting. Provided with snuff that can give you a feeling.

(Preferred Embodiments) The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate one embodiment of the present invention.

1 and 2 are cross-sectional views of a cigarette-shaped snuff 10 of the present invention, and FIG. 3 is an exploded perspective view of another example.

Snuff cigarette 10 of the present invention as shown in the first to third figures
The cigarette molded body 1 is molded to be breathable with a resin binder and impregnated with nicotine, and a cylindrical exterior material 2 made of paper or plastic material is provided around the cigarette molded body 1, as shown in the second figure. The mouthpiece is equipped with a filter (mouthpiece) 3, which is used in conventional cigarettes, and as shown in Figure 3,
The cylindrical exterior material 2 is divided into two parts, and one member 2' is provided with a holding member 5 for holding the cigarette molded product 1 to hold the cigarette molded product 1.
By making the molded body 1 removable and replaceable as necessary, it can be used like a conventional cigarette without igniting, giving the user the feeling of smoking a cigarette. be.

In these cases as well, in order to prevent the cigarette molded body 1 impregnated with or attached with nicotine from touching the lips or tongue, a mouthpiece 3 is provided on one side, or the edge of the exterior material 2 is closed as shown in FIGS. 1 to 5. It is preferable to provide a certain amount of space between the parts. Further, in any of the illustrated examples, other fragrances may be mixed in when forming the cigarette.

As mentioned above, the main feature of the snuff cigarette 10 of the present invention is that the tobacco powder is molded into a breathable form using a resin binder and impregnated with nicotine, so this point will be explained in more detail.

The purpose of molding tobacco powder with a resin binder to make it breathable is that it would be disadvantageous in terms of the manufacturing process to shape tobacco powder into a cylindrical shape using paper, as in conventional cigarettes, and if the cigarette breaks, etc. This is to prevent cigarette powder from scattering and contaminating the surrounding area, and even if the cigarette is not broken or damaged, the powder may spill from the tip or mouthpiece, making it unsanitary and unsuitable for use. This problem is also solved because it causes discomfort to some people.

The purpose of making the cigarette molded body breathable is to make it easier to inhale the tobacco aroma, trace components, and nicotine generated from the tobacco powder.

The tobacco leaves used in the present invention may be any of the crushed tobacco leaves used in conventional cigarettes and pipe tobacco, and the size of the crushed tobacco leaves is not the same as that of conventional crushed tobacco leaves. Any conventionally known tobacco powder can be used.

The resin binder for molding the tobacco powder is not particularly limited as long as it is a material that can solidify the tobacco powder into a certain shape while maintaining air permeability.

For example, starch, casein, gelatin, gum arabic, polyvinyl alcohol, polyacrylamide, carboxymethylcellulose, polyvinylpyrrolidone, polyacrylic acid or their water-soluble salts, polyvinyl acetate, vinyl acetate-acrylic ester polymer, polyacrylic ester Any resin binder, natural or synthetic, may be used, such as epoxy resins, phenolic resins, melamine resins, alkyd resins, natural rubber, synthetic rubber, polyurethane resins, and the like.

When using the above-mentioned resin binders, a melt of the resin binder, an aqueous solution, an emulsion, a latex, or an organic solvent solution with a concentration of about 1 to 50% by weight is added in an amount of about 100 parts by weight of the resin binder per 100 parts by weight of tobacco powder. It may be absorbed into tobacco powder in a proportion of 1 to 100 parts by weight to impart stickiness to the tobacco powder, molded into a desired shape, and dried.

A particularly preferred method in the present invention is a method in which a polyol component and a polyisocyanate component, which are raw materials for a polyurethane resin, are used to mold tobacco powder and produce a polyurethane resin. According to this method, since the polyol component and polyisocyanate component are generally liquid at room temperature, there is no need to use water or organic solvents that may deteriorate the quality of the tobacco powder when they are absorbed into the tobacco powder. Therefore, drying of these solvents and the like is not necessary, which is preferable in terms of the quality of the obtained product and the manufacturing process.

This method includes, for example, the following preferred embodiments.

(1) Tobacco powder is simultaneously impregnated with or adhered to a polyol component and a polyisocyanate component, and before or at the beginning of the reaction of both components during the impregnation or adhesion, the impregnation or adhesion is made into a certain shape and the reaction is stopped. A method of advancing and binding tobacco powder in a breathable manner.

(2) After pre-impregnating or adhering either the polyol component or the polyisocyanate component to the tobacco powder, the impregnated or adhered body is impregnated with or adhered to either the polyisocyanate component or the polyol component, and the same as above. How to form into.

(3) Tobacco powder is impregnated with or attached to either a polyol component or a polyisocyanate component in advance, while another tobacco powder is impregnated with or attached to either a polyol component or a polyisocyanate component, and these impregnated or A method in which the deposits are mixed together and the polyol component and polyisocyanate component are reacted and molded in the same manner as above.

The polyol component used in the above method is a polyol component commonly used in conventionally known methods for producing polyurethane resins, such as ethylene glycol, propylene glycol, diethylene glycol, 1,4-butanediol, 1, Diols such as 6-hexanediol, polyhydric alcohols such as glycerin, trimethylolpropane, diglycerin, and pentaerythritol, polyether polyols obtained by polymerizing alkylene oxides such as ethylene oxide and propylene oxide using the above polyols as initiators; Polyester polyols obtained by polymerizing polyols such as the above and polybasic acids, polyether polyester polyols composed of the above polyether polyols and polybasic acids, various other sugars such as cellulose, low molecular weight polyvinyl alcohol, polyvinyl acetate. Any partially saponified product, hydroxy-modified acrylic resin, or a mixture thereof can be used.

Any of the above polyol components can be used alone or as a mixture, but in order to provide sufficient strength and sufficient air permeability with the small amount of polyurethane resin produced, it is necessary to use at least 5% by weight of the polyol component. Preferably, 10% by weight or more of a trifunctional or higher functional polyol is used.

It is preferable to use polyol components as described above that are liquid at room temperature, and those that are not liquid at room temperature are preferably mixed with those that are liquid at room temperature for use. Further, a small amount of an organic solvent may be used in combination.

These polyol components may contain a small amount of water as a blowing agent, a small amount of nicotine, or various flavoring agents and additives for tobacco. For example, by incorporating water in the amount of 1 to 10% of the total weight of the polyol, the resulting polyurethane resin becomes foamable, so a small amount of polyurethane resin can improve breathability and strength. This is preferred because a cigarette molded article can be obtained.

The amount of the polyol component impregnated or attached to the tobacco powder is preferably such that the tobacco powder that has absorbed the polyol component feels slightly damp, for example, about 10 to 100 parts by weight per 100 parts by weight of the tobacco powder. If the amount used is too small, binding of the tobacco powder will be insufficient and it will be difficult to obtain a molded product with sufficient strength, which is undesirable.On the other hand, if it is too large, the air permeability of the resulting cigarette molded product will decrease, which is undesirable. .

Further, the polyisocyanate component used in the present invention is also a polyisocyanate component that has been conventionally used in the production of polyurethane resins, like the above-mentioned polyol component, such as 4,4'-diphenylmethane diisocyanate (MDI), water addition
MDI, isophorone diisocyanate, 1,3-
xylylene diisocyanate, 1,4-xylylene diisocyanate, 2,4-tolylene diisocyanate, 2,6-tolylene diisocyanate,
1,5-naphthalene diisocyanate, m-phenylene diisocyanate, P-phenylene diisocyanate, etc., or urethane preforms obtained by reacting these organic polyisocyanates with low molecular weight polyols or polyamines to form terminal isocyanates. Of course, polymers and the like can also be used.

Most of the polyisocyanate components mentioned above are liquid at room temperature, but those that are not liquid at room temperature may be made into a liquid by raising the temperature a little, or mixed with a liquid before use. The terminals are reacted with the polyol component at an excess NCO ratio.
Preferably, it is used as a liquid prepolymer of NCO. Further, a small amount of an organic solvent may be used in combination.

The amount of these polyisocyanate components used is
It varies depending on the amount of the polyol component, and the NCO/OH ratio with the polyol component is in the range of about 2/1 to 1/2, preferably about 1.2/1 to 1/1.2. range, more preferably a ratio of about 1/1. Expressed by weight, 5 parts per 100 parts by weight of tobacco powder
50 parts by weight is preferred.

Tobacco powder is bound using the polyol component and polyisocyanate component as described above.
In the method (3) above, since the polyol component and the polyisocyanate component are simultaneously impregnated or attached to the tobacco powder, the reaction between the polyol component and the polyisocyanate component starts at the same time as the impregnation or attachment.
Therefore, it is preferable to impregnate or adhere quickly and form a molded article in a short time. However, if a blocked polyisocyanate component that does not react at room temperature but reacts above a certain temperature is used as the polyisocyanate component, this problem will not occur, and the polyol component and polyisocyanate component can be sufficiently mixed into tobacco powder. The object of the present invention can be achieved by impregnating or adhering it to a material, shaping it into a desired shape using a mold, etc., and then heat-treating it.

Further, the method (2) is a modification of the method (1), and is preferred because it allows the storage of a large amount of tobacco powder that has been impregnated with or adhered to a polyol component or polyisocyanate component in advance.

In addition, the method (3) above is also a modification of the method (2), and in this method, tobacco powder impregnated with or attached with a polyol component and tobacco powder impregnated with or attached with a polyisocyanate component are respectively used. Since both are prepared separately, they are stable when used alone, and both can be stocked in large quantities, and if necessary, they can be mixed to form the required amount of cigarette molded products. This is preferable because it allows
Although heating is not particularly necessary during the above-described molding, the reaction between the polyol component and the polyisocyanate component may be promoted by heating.

The cigarette molded article obtained as described above may have any shape and is not particularly limited. For example, it may be formed into a large block shape and then processed into a required shape, such as a cylindrical shape as shown in the first figure, or another shape, or a cylindrical shape as shown in the first figure. Alternatively, by preparing a mold of another shape and binding the tobacco powder within the mold, it is possible to form a molded cigarette according to the mold.

The cigarette molded article 1 used in the present invention is obtained as described above, has the shape of a cigarette as shown in FIGS. 1 to 3, and can be inhaled through the mouth to feel the scent of tobacco. If left as is, it would lack nicotine and would be insufficient as a snuff cigarette, so it is preferable to mix nicotine into it during or after the above-mentioned molding. The method of mixing may be by mixing the tobacco powder, resin binder, polyol component, or polyisocyanate component and all of these components before molding, or by mixing it during molding, or by adding nicotine alcohol solution etc. after molding. Any method such as a method of infiltrating the molded body may be used. The amount of nicotine mixed into tobacco powder
Approximately 0.01 to 10 parts by weight per 100 parts by weight is sufficient, and various flavoring agents in addition to nicotine can also be included at the same time.

(Operation/Effect) According to the present invention as described above, since the cigarette molded body 1 is formed to be breathable and impregnated with nicotine, there is no need to light it by inhaling it as a cigarette. It produces no smoke or ash, and provides the same effect as smoking a cigarette without inhaling any tar or carbon monoxide.

Furthermore, in the present invention, since no fire is used by using the cigarette molded article 1, there is no generation of smoke or ash, which does not pollute the surrounding environment or cause inconvenience to non-smokers. You can use it freely both indoors and in the car. Furthermore, for the same reason, there is no inhalation of tar components, carbon monoxide, etc., which are the main harmful substances in cigarettes, so there is no harm to the smoker's health.
