Description

  The present invention relates to an oral tobacco product for a user to absorb tobacco components via saliva.

Traditionally, cigarettes have been enjoyed as a luxury item, but recently smokeless cigarettes have been attracting attention for their use, and such smokeless cigarettes are also used in non-smoking rooms on airplanes and trains. Is allowed.
One of the smokeless tobaccos, snus (SNUS) as a tobacco product for oral use has as a main component a finely cut tobacco material, and this tobacco product contains a lot of moisture.

More specifically, this type of snus is classified into a loose type in which a cigarette is not wrapped or a portion type in which a cigarette is wrapped with a nonwoven fabric or the like, a so-called pouch type.
In the case of pouch-type snus, the user puts the snus directly into the oral cavity and sandwiches it between the upper lip and the gums to enjoy the fragrance, while absorbing tobacco components extracted from saliva into the body from the gums.

By the way, since tobacco tobacco products represented by snus have a lot of moisture contained in tobacco, bacteria easily propagate in tobacco tobacco at room temperature. Therefore, long-term storage at room temperature must be avoided for this type of oral tobacco product. For this reason, oral tobacco products are stored refrigerated, or salt is added to tobacco products. Such refrigeration and the addition of salt are useful for suppressing bacterial growth against tobacco.
In addition, a technique for sterilizing bacteria in tobacco with radiation is also known (Patent Document 1).

US Patent Application Publication No. 2008/0173319

Refrigerated storage of oral tobacco products must be performed not only at the retailer, but also during the transport of the tobacco product to the retailer. Therefore, refrigerated storage of oral tobacco products requires significant costs.
On the other hand, if a large amount of salt is added to the tobacco cigarette in order to improve the storage property of the oral tobacco product, the original flavor and flavor of the tobacco tobacco are impaired, which is not preferable.

Furthermore, the sterilization treatment by radiation requires expensive equipment as compared with refrigerated storage, and since such equipment handles radiation, costs for safety measures are also required.
An object of the present invention is to provide an oral tobacco product that suppresses the growth of bacteria without impairing the flavor and flavor of tobacco and enables the distribution and storage of oral tobacco products at room temperature. .

  In order to achieve the above object, the tobacco product for oral cavity of the present invention is a tobacco pouch, comprising a mixture mainly composed of tobacco particles made of tobacco materials and a wrapping material for wrapping the mixture. A cigarette pouch that allows the user to absorb tobacco components through saliva and an openable / closable storage case for storing the tobacco pouch, wherein at least one of the tobacco pouch and the storage case contains an inorganic antibacterial agent It is out.

Specifically, the inorganic antibacterial agent can include zeolite and silver supported on the zeolite, and the packaging material may be a non-woven sheet.
Since the tobacco product for oral cavity has the inorganic antibacterial agent attached to the tobacco pouch or the storage case, it is possible to suppress the growth of bacteria in the tobacco pouch. Therefore, when storing an oral tobacco product, it can be stored at room temperature, and it is not necessary to refrigerate the tobacco product during transportation and storage of the oral tobacco product. As a result, the cost required for transportation and storage of tobacco products can be reduced.

  The tobacco particles desirably have a pH of 6.5 to 9.5, and the tobacco particles desirably have a moisture content of 15 to 50% by weight.

  According to the tobacco product for oral cavity of the present invention, the growth of bacteria can be suppressed without impairing the flavor and flavor of tobacco, and the oral tobacco product can be distributed and stored at room temperature.

It is the schematic which showed the tobacco product for oral cavity containing the inorganic antibacterial agent which concerns on this invention. It is a block diagram which shows the manufacturing process of the tobacco product for oral cavity shown in FIG. It is a fragmentary sectional view of the case body of a storage case, a mat, and a lid.

An oral tobacco product 1 shown in FIG. 1 includes a large number of tobacco pouches 2 and a portable storage case 4 for storing these tobacco pouches 2.
The tobacco pouch 2 includes a mixture containing tobacco particles as a main component and a non-woven sheet enclosing the mixture. Specifically, the tobacco particles are obtained by cutting or pulverizing tobacco materials and have a particle size of 2 mm or less.

Such a cigarette pouch 2 is taken out of the storage case 4 and used in the oral cavity of the user. Specifically, the tobacco pouch 2 is sandwiched between the upper lip of the user and the gums, and the tobacco components of the tobacco particles extracted into the saliva are absorbed from the gums into the body.
On the other hand, the housing case 4 includes a case body 6, a mat 8, and a lid 10. The case body 6 has a flat cylindrical shape and has an opening 7 on the upper surface. The opening 7 has a circular shape that is convex upward, and can be opened and closed by a lid 10.

The mat 8 has a circular shape, has an outer diameter substantially equal to the inner diameter of the inner wall surface 14 in the case body 6, and is disposed on the bottom 12 of the case body 6. Therefore, the tobacco pouch 2 in the housing case 4 is in a state of being stacked on the upper surface of the mat 8.
The lid 10 is circular and has the same outer diameter as the outer diameter of the case body 6. A substantially circular stepped recess 16 is formed on the upper surface of the lid 10, and the stepped recess 16 has a bottom 17 and an annular lid rest 15 surrounding the bottom 17. Is shallower than the bottom 17. A hinge 18 is disposed on the outer periphery of the lid rest 15, and a circular cover 20 is attached to the hinge 18. The cover 20 has an outer diameter substantially equal to the outer diameter of the lid rest 15. Therefore, when the cover 20 is fitted in the recess 16, the cover 20 closes the recess 16 with the outer peripheral portion thereof being in close contact with the lid rest 15 of the recess 16. On the other hand, when the cover 20 is rotated upward about the hinge 18 from this closed state, the cover 20 opens the recess 16. That is, the cover 20 can open and close the recess 16. When the recess 16 is closed by the cover 20, the outer peripheral portion of the upper surface of the lid 10 and the upper surface of the cover 20 are flush with each other.

  A knob 22 projects from the outer peripheral edge of the cover 20, and the knob 22 and the hinge 18 are separated from each other in the diameter direction of the cover 20. On the other hand, a recess 27 that can receive the knob 22 is formed in the outer peripheral portion of the lid 10. Such a knob 22 is useful for facilitating the opening operation of the cover 20. Further, claws 24 are formed on the outer peripheral edge of the cover 20 in the vicinity of the knob 22 and on both sides of the knob 22, respectively. On the other hand, the outer periphery of the recess 16 is engaged with each claw 24. A hole 26 is formed. Therefore, when the cover 20 is closed, each claw 24 is fitted in the corresponding engagement hole 26, and the cover 20 is maintained in the closed state.

The above-described recess 16 has a volume capable of accommodating several tobacco pouches 2. Therefore, the lid 10 can be used as a waste bin for temporarily storing the used tobacco pouch 2. That is, the storage case 4 can store the tobacco pouch 2 before use and the tobacco pouch 2 after use separately.
A circular recess is also formed in the lower surface of the lid 10, and this recess has an inner diameter slightly larger than the outer diameter of the opening 7 described above, and can accept the opening 7. Further, the recessed ceiling surface 28 (see FIG. 3) also serves as a pressing surface for pressing the tobacco pouch 2 in the case body 6.

  The user can take out the tobacco pouch 2 from the inside of the case body 6 through the opening 7 by opening the lid 10 from the housing case 4 to expose the opening 7. When the extracted tobacco pouch 2 is sandwiched between the upper lip and gums of the user, the tobacco components of the tobacco particles in the tobacco pouch 2 are extracted into saliva and absorbed into the user's body through the saliva. The Therefore, the user can enjoy the aroma of tobacco particles while absorbing the tobacco component.

  During the use of the cigarette pouch 2, no smoke is emitted from the cigarette pouch 2, so that the user can use the cigarette pouch 2 regardless of the location. The used tobacco pouch 2 can be accommodated in the recess 16 of the lid 10 by picking the knob 22 of the cover 20 with a finger and lifting and opening the cover 20.

By the way, since the tobacco particles in the tobacco pouch 2 promote the extraction of tobacco components by saliva, the amount of water is larger than that of a normal cigarette, and therefore, bacteria are likely to grow on the tobacco particles.
Therefore, the granular inorganic antibacterial agent 30 is attached to the entire packaging material of the tobacco pouch 2, that is, the nonwoven fabric. Specifically, in the case of the present embodiment, silver zeolite is used as the inorganic antibacterial agent 30, and this silver zeolite contains silver supported on the zeolite. Such silver zeolite can contact the tobacco particles in the tobacco pouch 2.

  Here, Zeomic (trademark) manufactured by Sinanen Zeomic Co., Ltd. is suitable as the silver zeolite. This zeomic has a particle diameter of about 1 μm, and adsorbs water molecules in the micropores, while releasing the adsorbed water molecules from the micropores. Therefore, the silver zeolite has not only the original antibacterial action but also the action of adjusting the water content in the tobacco pouch 2. That is, the silver zeolite exhibits a moisturizing function that maintains the moisture content of the tobacco particles in the tobacco pouch 2.

  Silver zeolite is alkaline and its pH value range (7-9) is approximately equal to the pH value range of tobacco particles that are also alkaline. Therefore, the silver zeolite does not change the tobacco particles to acidity. That is, the flavor of tobacco particles is not impaired by the silver zeolite.

  In order to verify the antibacterial effect of silver zeolite, each of the tobacco pouch 2 of the present example to which silver zeolite was attached and the tobacco pouch of the comparative example without silver zeolite were prepared, and the tobacco pouches of these tobacco pouches were intentionally produced on the tobacco particles. Each fungus was added. Specifically, this test was conducted by the Japanese Pharmacopoeia Kanten plate pour method. In addition, about 300 E. coli were added per 1 g of tobacco particles. The tobacco pouches of these examples and comparative examples were allowed to stand at room temperature for 1 week, after which the number of viable bacteria present in the tobacco pouches of the examples and comparative examples was examined, and the following test results were obtained. The number of viable bacteria in the tobacco pouch of the comparative example was increased to about 1000 per 1 g of tobacco particles, whereas in the case of the tobacco pouch 2 of the example, no change was observed in the number of viable bacteria.

  On the other hand, case devices of Examples and Comparative Examples were prepared. The case device of the embodiment has an antibacterial layer 32 applied to the entire inner wall surface 14 of the case body 6, the mat 8, and the ceiling surface 28 of the lid 10, and these antibacterial layers 32 contain silver zeolite. The case device of the comparative example is different from the case device of the example only in that the antibacterial layer 32 is not included. And the tobacco pouch of the comparative example to which the living bacteria were added as described above was accommodated in the case devices of these examples and comparative examples, respectively, and the case devices of these examples and comparative examples were left at room temperature for one week. . Thereafter, the number of viable bacteria present in the tobacco pouch was examined, and the following test results were obtained. In the case of the tobacco pouch in the case device of the comparative example, the number of viable bacteria was increased to about 1000 per 1 g of tobacco particles, while in the case of the tobacco pouch 2 in the case device of the example product, There was no change in the number of bacteria.

This indicates that if the antibacterial layer 32 is formed on any of the inner wall surface 14 of the case body 6, the mat 8, and the ceiling surface 28 of the lid 10, the number of bacteria that grow on the tobacco particles can be suppressed.
Therefore, the combination of the tobacco pouch 2 of the embodiment and the case device of the embodiment is optimal for more effectively suppressing the bacteria that grow on the tobacco particles in the tobacco pouch 2.

  In addition, since a lot of water | moisture content is contained in a tobacco particle, the water | moisture content containing the tobacco component of a tobacco particle may ooze out to the outer surface of the tobacco pouch 2 during storage of the tobacco pouch 2. In order to compensate for the loss of the tobacco component, the packaging material of the tobacco pouch 2, that is, the non-woven fabric sheet, the inner wall surface 14 of the case body 6, the upper surface of the mat 8, and the ceiling surface 28 of the lid 10 are filled with food. A fragrance 34 may be attached.

Moreover, when a coupon is accommodated in the accommodation case 4, the food fragrance | flavor 34 can be made to adhere also to this coupon. In addition, when the food flavor 34 is used, it is desirable that the oral tobacco product 1 contains a humectant such as glycerin or propylene glycol.
As the food flavor 34, menthol, mint, vanilla, apricot, tea, cocoa, licorice, honey and the like can be used alone or in combination. In addition, when the food flavor 34 is attached to the packaging material of the tobacco pouch 2, since the tobacco particles are alkaline as described above, an acidic food flavor is not suitable.

The food flavor 34 is used in the form of a powder or a liquid form dissolved in a solvent. Here, water, alcohol, glycerin, propylene glycol or the like can be used as the solvent.
When the food flavor 34 is attached to the tobacco pouch 2, glycerin that also functions as a moisturizing agent is used for the food flavor 34, and this glycerin is applied to the tobacco pouch 2 by 1% by weight of the mixture.

  On the other hand, when the food fragrance 34 is attached to the housing case 4 side, a menthol solution in which 1% by weight of menthol is dissolved in alcohol is used as the food fragrance 34, and this menthol solution is used as the inner wall surface 14 of the case body 6. At least one of the surface of the mat 8 and the ceiling surface 28 of the lid 20 is spray coated.

Next, the manufacturing process of the tobacco pouch 2 will be described.
