Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to snuff, and more specifically, the present invention relates to snuff, which does not cause discomfort or adverse effects on the surroundings such as smoke, odor, or ash.
Furthermore, the purpose is to provide snuff that does not harm the health of smokers themselves.

(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, since 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. Because it did not contain any smoke, it did not have a smoking sensation, and it did not become very popular.

On the other hand, alternative cigarettes (e.g. , Made in the USA, etc. Product name: Fla
vor) 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 the 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 body breathably bound by a resin binder and an exterior material surrounding the molded body.

(Function) A snuff cigarette that can give a smoking sensation without igniting by binding chopped tobacco leaves (tobacco powder) with a resin binder in a breathable manner and wrapping it in a cigarette-like exterior material. is provided.

(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 to 4 are cross-sectional views of the cigarette-like snuff 10 of the present invention, and FIG. 5 is an exploded perspective view of another example.

As shown in the first to fifth figures, the snuff cigarette 1 of the present invention has a cylindrical exterior material 2 made of paper or plastic material surrounding a cigarette molded body 1 made of a resin binder to be air permeable.
As shown in the second figure, the filter (mouthpiece) 3 used in conventional cigarettes is attached to the mouthpiece.
Furthermore, as shown in FIGS. 3 and 4, a breathable material 4 impregnated with or attached with nicotine may be combined in some part, or as shown in FIG. 5, a cylindrical exterior material 2 may be used. is divided into two parts, and one member 2' is provided with a holding member 5 for holding the cigarette molded object 1 to hold the cigarette molded object 1, and this can be attached to and detached from the other member 2'', as necessary. By making the molded body 1 replaceable, it can be used in the same way as a conventional cigarette without igniting, giving the user the sensation of smoking a cigarette.

In the example shown in the third figure or the fourth figure, the nicotine-impregnated or attached body 4 is designed to prevent the nicotine-impregnated or attached body 4 from touching the lips or the tongue even if the side of the nicotine-impregnated or attached body 4 is accidentally added to the mouth. 4 is preferably attached to a certain extent inside the end of the exterior material 2.

The products shown in Figures 1, 2, and 5 allow you to feel the flavor of the cigarette when you inhale, but this alone does not provide enough nicotine, which is the main component of cigarettes, so when the cigarette is formed, Alternatively, it is preferable to mix an appropriate amount of nicotine into the molding after molding. In the cases shown in the third and fourth figures, nicotine may or may not be mixed into the smoke repair molded body l.

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 with a resin binder to make it breathable, so this point will be explained in more detail.

The purpose of molding tobacco powder into a breathable form using a resin binder is that forming tobacco powder into a cylindrical shape using paper as with conventional cigarettes is disadvantageous in terms of the manufacturing process, and it also prevents the cigarette from breaking. This is to prevent cigarette powder from scattering and contaminating the surrounding area, and even if the cigarette does not break or break, the powder may spill from the tip or mouthpiece, which is unsanitary. This also causes discomfort to the user, so this problem is also solved.

The purpose of making the cigarette molded body breathable is to make it easier to inhale the tobacco aroma and trace components 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 vibe cigarettes, and the size of the crushed tobacco leaves is not the same as that of conventional cigarettes, 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 natural or synthetic resin binder may be used, such as epoxy resin, phenolic resin, melamine resin, alkyd resin, natural rubber, synthetic rubber, polyurethane resin, etc.

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. 1
It may be absorbed into tobacco powder in a proportion of 1 to 100 parts by weight to impart tackiness to the tobacco powder, mold it into a desired shape, and dry it.

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 absorbing them 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 in the impregnated or adhered substance, the impregnated or adhered substance is made into a certain shape, and the A method of binding tobacco powder in a breathable manner by advancing it.

(2) After pre-impregnating or adhering either the polyol component or the polyisocyanate component to 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) Preliminarily impregnating or adhering either a polyol component or a polyisocyanate component to tobacco powder;
A method of impregnating or adhering either a polyol component or a polyisocyanate component to another tobacco powder, mixing these impregnated or adhering substances with each other, causing the polyol component and the polyisocyanate component to react, and molding 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 obtained from the above polyether polyols and polybasic acids, various other sugars such as cellulose, low molecular weight polyvinyl alcohol, polyacetic acid. Any partially saponified vinyl, 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 preferable to use at least 5% by weight of the polyol component. 101
It is preferable to use 1% by weight or more of a trifunctional or higher functional polyol.

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. Also, a small amount of an organic solvent may be used in combination.

These polyol components contain a small amount of water as a blowing agent,
Small amounts of nicotine or various tobacco flavorings and additives may also be included. For example, a total of 1
By containing about 10% by weight of water,
Since the polyurethane resin produced is foamable, a molded cigarette with good air permeability and strength can be obtained with a small amount of polyurethane resin, which is preferable.

The amount of polyol component impregnated or attached to tobacco powder is
Tobacco powder that has absorbed the polyol component has a slightly moist feel, for example, about 10 to 100 parts by weight per 100 parts by weight of tobacco powder.
If the amount used is too small, the binding of tobacco powder will be insufficient,
This is not preferable because it becomes difficult to obtain a molded product with sufficient strength, and on the other hand, if the amount is too large, the air permeability of the resulting cigarette molded product decreases, which is not preferred.

Furthermore, 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, and includes, for example, 4,4'-diphenylmethane diisocyanate (MDI), water-added MDI, isophorone diisocyanate, 1゜3-xylylene diisocyanate), 1.4-
Xylylene diisocyanate, 2.4-tolylene diisocyanate, 2.6-tolylene diisocyanate, 1
．． 5-naphthalene diisocyanate, m-phenyl 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. It is preferable to react with the polyol component in an excess proportion of NCO and use it as a liquid prepolymer of terminal NGOs. Further, a small amount of an organic solvent may be used in combination.

The amount of these polyisocyanate components used varies depending on the amount of the polyol component, and the ratio of N COlo H to the polyol component is about 2/1 to 1.
/2 range, preferably 1.2/l to 1/1.2
more preferably a ratio of about 171. Expressed by weight, it is preferably 5 to 50 parts by weight per 100 parts by weight of tobacco powder.

Tobacco powder is bound using the polyol component and polyisocyanate component as described above, but in the method (3) above, the tobacco powder is impregnated with or attached to the polyol component and the polyisocyanate component at the same time. The reaction between the polyol component and the polyisocyanate component starts at the same time as impregnation or adhesion, and 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 subjecting it to heat treatment.

Further, the method (2) is a modification of the method (1), and is preferred because it allows a large amount of tobacco powder impregnated with or attached to the polyol component or polyisocyanate component to be stocked in advance.

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 separately prepared. Since both are stable when used alone, both can be stocked in large quantities, and if necessary, the required amount of cigarette molded products can be made by mixing the two. preferable. 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 product obtained in the above manner may have any shape, but is not particularly limited. For example, it may be molded into a large block shape, and a shape that requires this, such as a cylindrical shape as shown in the first figure, Alternatively, it may be processed into other shapes, or by preparing a mold with a cylindrical shape as shown in the first figure or other shapes and consolidating the tobacco powder within the mold, the tobacco powder can be processed according to the mold. It can be made into a cigarette molded article.

The cigarette molded article 1 used in the present invention is obtained as described above and has the shape of a cigarette as shown in FIG. 1 to FIG. Since nicotine may be insufficient for use as a snuff cigarette due to a lack of nicotine, it is preferable to mix nicotine into the product 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 may be used, such as a method of incorporating it into a molded article. The amount of nicotine mixed in is 0 per 100 parts by weight of tobacco powder.
．． About 0.01 to 10 parts by weight is sufficient, and various fragrances and the like other than nicotine can also be included at the same time.

Alternatively, instead of the above method, nicotine is not mixed into the cigarette molded product 1, and a molded product 4 containing nicotine is separately prepared as shown in FIGS. , it can also be used in combination with the above-mentioned cigarette molded article 1.

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

In particular, by incorporating nicotine and other flavors into the cigarette molded product 1, or by combining it with the nicotine mixture 4, nicotine and other tobacco flavors can be absorbed at the same time, making it an alternative to conventional cigarettes. It shows sufficient effect as a.

Moreover, in the present invention, by using the cigarette molded body 1,
Since no fire is used, there is no smoke or ash, and it does not pollute the surrounding environment or bother non-smokers, so it can be used indoors or in a 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.

Hereinafter, the present invention will be explained in more detail according to Examples. In the text, parts or percentages are based on weight unless otherwise specified.
