Oral pouch product and method of manufacturing the same

[0001] The present invention relates to an oral pouch product and a method for manufacturing the same.

[0002]

[0003] Oral pouch products are a type of smoking product that can be used by placing the product between the cheek and gum, or between the gum and lip, and maintaining it for a certain period of time.

[0004] Oral pouch products generally consist of a filling material containing an active ingredient and a packaging material that encloses the filling material. The packaging material has salivary permeability or salivary solubility, and the active ingredient contained in the enclosed filling material is released by the user's saliva and can provide satisfaction to the user through absorption into the body via microvessels of the oral mucosa, etc.

[0005] Oral pouch products vary in terms of total pouch weight or the content of active ingredients included in the filling material, depending on the release target of the active ingredient. Therefore, while recommended usage times are provided based on the target, there is a problem in that users find it difficult to check this every time.

[0006] In addition, oral pouch products do not allow for checking the end time of use; therefore, if the product is used for a longer period than the recommended time, a foreign body sensation in the throat may occur, and the active ingredients may be absorbed through the digestive system, potentially causing gastrointestinal discomfort or nausea, which poses a problem.

[0039] FIG. 1 is a schematic drawing illustrating an oral pouch product according to one embodiment of the present invention.

[0040] One embodiment of the present invention provides an oral pouch product comprising: a packaging material having a cavity inside which at least a portion of the periphery is sealed; a filler material enclosed in the cavity and containing an active ingredient; and a coating material provided on at least a portion of the outer surface of the packaging material and containing a sugar alcohol-based fiber, wherein the sugar alcohol-based fiber contains a sugar alcohol-based compound having a water solubility of 10 g / 100 g or more and 100 g / 100 g or less at 25 ℃.

[0041] An oral pouch product according to one embodiment of the present invention can effectively provide a variety of flavors to the user and achieve excellent smoking properties. In addition, the oral pouch product allows the user to easily recognize the usage time through changes in flavor during use.

[0042] Referring to FIG. 1, the oral pouch product (100) may include a packaging material (110), a filling material (120) provided in an internal cavity of the packaging material (110), and a coating material (130) provided on the outer surface of the packaging material (110). The oral pouch product (100) may have a size and structure that can fit comfortably between the user's cheek and gums, or between the gums and lips. The oral pouch product (100) may be provided in various shapes including spherical, square, rectangular, crescent, elliptical, and cube shapes. FIG. 1 discloses an embodiment in which the oral pouch product (100) is provided in a rectangular shape, but the shape of the oral pouch product (100) is not limited thereto.

[0043] According to one embodiment of the present invention, the weight of the oral pouch product may be 0.2 g or more and 1.5 g or less, 0.4 g or more and 1.3 g or less, 0.6 g or more and 1.1 g or less, 0.7 g or more and 0.9 g or less, 0.2 g or more and 0.8 g or less, 0.3 g or more and 0.6 g or less, or 0.8 g or more and 1.5 g or less. When the weight of the oral pouch product is within the aforementioned range, there is an advantage that the user can use the oral pouch product more comfortably.

[0044] According to one embodiment of the present invention, the packaging material may form a cavity inside by sealing at least a portion of its periphery. The method of sealing the packaging material may use any method used in the art without limitation. For example, the periphery of the packaging material may be sealed using methods such as heat fusion or ultrasonic fusion. Referring to FIG. 1, the periphery (111) where the packaging material (110) is sealed may be both ends of the packaging material (110), but is not limited thereto.

[0045] According to one embodiment of the present invention, the packaging material may be manufactured from a material having suitable saliva permeability and a certain strength so as not to dissolve in saliva or tear. Additionally, the packaging material may be manufactured using a material having a softness sufficient for a user to use in the oral cavity. Furthermore, the packaging material may be manufactured using a material having sealable properties to contain an internal filler. For example, the packaging material may be manufactured from a non-woven fabric material.

[0046] According to one embodiment of the present invention, the packaging material may be a nonwoven fabric manufactured using fibers having a fineness of 1 denier or more. Additionally, the packaging material may be a nonwoven fabric manufactured using fibers having a diameter of 10 μm or more. Specifically, the fineness of the fibers may be 1 denier or more and 10 denier or less, 2 denier or more and 8 denier or less, or 4 denier or more and 6 denier or less. Additionally, the diameter of the fibers may be 10 μm or more and 30 μm or less, 15 μm or more and 25 μm or less, 20 μm or more and 25 μm or less, or 10 μm or more and 20 μm or less. By using fibers having the aforementioned fineness and / or diameter, a packaging material with excellent moisture transport characteristics and strength can be easily realized.

[0047] In addition, the above packaging material may be a nonwoven fabric made of staple fibers having the aforementioned fineness and / or diameter. In this case, the staple fibers are fibers having discontinuous lengths and may be obtained by cutting a continuous filament.

[0048] According to one embodiment of the present invention, the basis weight of the packaging material may be 10 g / m² or more and 50 g / m² or less, 20 g / m² or more and 40 g / m² or less, 10 g / m² or more and 30 g / m² or less, 15 g / m² or more and 25 g / m² or less, or 25 g / m² or more and 50 g / m² or less. In this case, basis weight refers to weight per area. When the basis weight of the packaging material is within the aforementioned range, the packaging material may have excellent moisture transport characteristics and strength.

[0049] According to one embodiment of the present invention, the thickness of the packaging material may be 50 μm or more and 300 μm or less, 80 μm or more and 280 μm or less, 100 μm or more and 250 μm or less, 130 μm or more and 200 μm or less, 150 μm or more and 180 μm or less, 50 μm or more and 240 μm or less, or 175 μm or more and 300 μm or less. When the thickness of the packaging material is within the aforementioned range, the packaging material may have excellent moisture transport characteristics and strength.

[0050] According to one embodiment of the present invention, the filler may include an active ingredient. The active ingredient may be a component that dissolves upon contact with saliva. Specifically, the active ingredient may include a nicotine compound. For example, the filler may include nicotine-containing granules. Meanwhile, the content of the nicotine compound included in the oral pouch product may be determined according to the smoking intensity of the desired nicotine pouch.

[0051] According to one embodiment of the present invention, the nicotine compound may be included in the form of a nicotine base and / or a nicotine salt. For example, the nicotine salt may include at least one of nicotine tartrate, nicotine hydrochloride, nicotine dihydrochloride, nicotine monotartrate, nicotine bitartartrate, nicotine bitartartrate dihydrate, nicotine sulfate, nicotine zinc chloride monohydrate, nicotine salicylate, nicotine benzoate, and nicotine polacrilex.

[0052] According to one embodiment of the present invention, the filler may further include an additive, and the additive may include at least one of a binder and a pH adjuster. In this case, the binder and the pH adjuster may be used without limitation as those used in the art.

[0053] The above binder can prevent the active ingredient from degrading during storage and impart a desired release rate of the active ingredient. For example, the binder may include at least one of hydroxypropyl cellulose (HPC), low-substituted hydroxypropyl cellulose (L-HPC), hydroxypropyl methylcellulose (HPMC), methyl cellulose (MC), polyvinyl pyrrolidone (PVP), and carboxymethyl cellulose (CMC).

[0054] The above pH adjuster can adjust the pH of the nicotine pouch filler to a pH at which nicotine can be absorbed, so that when the nicotine pouch is inserted into the oral cavity, the nicotine can be converted into a free-based nicotine form that can be rapidly absorbed. For example, the pH adjuster may include at least one of potassium hydroxide (KOH), sodium hydroxide (NaOH), potassium carbonate (K2CO3), sodium carbonate (Na2CO3), potassium bicarbonate (KHCO3), and sodium bicarbonate (NaHCO3).

[0055] According to one embodiment of the present invention, the oral pouch product may be of a dry type or a wet type depending on the moisture content of the filler. The filler may include one or more of a dry mixture and a wet mixture. The dry mixture may contain moisture of 3% by weight or less based on the total weight of the filler. The wet mixture may contain moisture of 40% by weight or more based on the total weight of the filler.

[0056] According to one embodiment of the present invention, the oral pouch product includes a coating material. As time passes while a user uses the oral pouch product, the soft coating material dissolves, allowing the user to confirm the end of use by touch by perceiving the difference in surface roughness between the coating material and the packaging material. Furthermore, as the sugar alcohol-based compound of the coating material completely dissolves, the user can confirm the end of use by taste by perceiving the difference in taste and flavor.

[0057] FIG. 2a is a cross-sectional view of an oral pouch product according to one embodiment of the present invention, and FIG. 2b is a cross-sectional view of an oral pouch product according to another embodiment of the present invention. Specifically, FIG. 2a and FIG. 2b illustrate cross-sectional views of an oral pouch product based on the AA' cross-sectional line of FIG. 1.

[0058] Referring to FIG. 2a, the packaging material (110) may include a sealed periphery (111) and an unsealed remaining center (112). For example, the periphery (111) of the packaging material (110) may be both ends. The center (112) of the packaging material (110) may refer to a portion in which a filler (120) is enclosed.

[0059] According to one embodiment of the present invention, a coating material may be formed on at least a portion of the outer surface of the packaging material. Referring to FIG. 2a, the coating material (130) may be provided on the entire surface of the packaging material (110). That is, the coating material (130) may be provided on both the outer surface of the peripheral portion (111) and the outer surface of the central portion (112).

[0060] According to one embodiment of the present invention, the coating material may be provided in a larger amount on the outer surface of the center than on the outer surface of the periphery. The coating material may not be formed on the outer surface of the periphery, or may be formed in a smaller amount than on the center. Referring to FIG. 2b, the coating material (130) may be provided only on the surface of the center (112) of the packaging material (110). As the user begins to use the product, the coating material (130) melts, allowing the user to perceive the difference in surface roughness between the coating material (130) and the packaging material (110). Furthermore, by perceiving that the difference in surface roughness between the periphery (111), where the coating material (130) is formed in small amounts or not formed at all, and the center (112), where the coating material (130) is formed in relatively large amounts, is similar, the user can easily sense the end time of use by touch.

[0061] According to one embodiment of the present invention, the amount of coating material provided in an oral pouch product can be varied depending on the release target of the active ingredient, the expected usage time, etc. For example, in the case of a small oral pouch product having a weight of 0.3 g or more and 0.5 g or less, the coating material may be formed in an amount such that most of it dissolves within a time of 20 minutes or more and 30 minutes or less. In addition, in the case of a general oral pouch product having a weight of approximately 1 g, the coating material may be formed in an amount such that most of it dissolves within about 1 hour. However, it is not limited thereto.

[0062] According to one embodiment of the present invention, the coating material may further include an edible softening agent. By further including the softening agent in the coating material, the difference in tactile sensation with the packaging material can be increased. The softening agent may be included in the coating raw material described below and spun by a meltblown method to form a coating material containing the softening agent. The softening agent may be selected to be edible and suitable for the meltblown process. For example, the softening agent may include at least one of citric acid, glycerin, gelatin, lecithin, alginate, pectin, guar gum, and agar.

[0063] According to one embodiment of the present invention, the thickness of the coating material may be 10 μm or more and 200 μm or less, 30 μm or more and 180 μm or less, 50 μm or more and 150 μm or less, 70 μm or more and 100 μm or less, 10 μm or more and 120 μm or less, or 100 μm or more and 200 μm or less. By adjusting the thickness of the coating material to the aforementioned range, the active ingredient can be effectively delivered to the user to achieve excellent smoking properties. Furthermore, when the thickness of the coating material is within the aforementioned range, taste and flavor can be effectively provided to the user, while allowing the user to easily recognize that the appropriate usage time is being completed.

[0064] According to one embodiment of the present invention, the coating material may be formed of a sugar alcohol-based fiber, and the sugar alcohol-based fiber may include a sugar alcohol-based compound having a water solubility at 25°C of 10 g / 100g or more and 100 g / 100g or less. That is, the sugar alcohol-based fiber may have a water solubility at 25°C of 10 g / 100g or more and 100 g / 100g or less. Specifically, the water solubility at 25°C of the sugar alcohol-based compound may be 20 g / 100g or more and 80 g / 100g or less, 40 g / 100g or more and 60 g / 100g or less, 20 g / 100g or more and 60 g / 100g or less, or 50 g / 100g or more and 100 g / 100g or less. By using a sugar alcohol-based compound having the aforementioned water solubility, taste and flavor can be provided to the user more effectively.

[0065] According to one embodiment of the present invention, the sugar alcohol-based fiber may be formed by melt-spinning the sugar alcohol-based compound using a melt-blown method. That is, a coating liquid in which the sugar alcohol-based compound is melted may be spun onto the surface of a packaging material via a melt-blown method to form a coating material. At this time, the coating liquid may contain a melt of the sugar alcohol-based compound. When using the melt-blown method, the coating liquid may be released in the form of fine fibers using high-pressure air or a high-speed airflow, and may be coated onto the surface of the packaging material in the form of fibers while cooling in the air. Meanwhile, in terms of controlling the viscosity of the coating liquid or increasing ease of manufacturing, the coating raw material containing the sugar alcohol-based compound may further include a solvent. For example, water and / or ethanol may be used as the solvent.

[0066] According to one embodiment of the present invention, the coating material may include meltblown sugar alcohol-based fibers. Specifically, the coating material may be provided in the form of a web formed from meltblown sugar alcohol-based fibers. When a coating material is formed through a conventional coating or application method, there was a problem in that it was not easy to stably provide active ingredients to the user in an oral pouch product. On the other hand, since the coating material has a web form formed from meltblown sugar alcohol-based fibers, excellent moisture transport characteristics can be secured, thereby enabling the continuous and stable provision of active ingredients to the user.

[0067] According to one embodiment of the present invention, the coating material may not contain a binder. As described above, the coating material is formed using a meltblown method, thereby enabling excellent adhesion to the packaging material. Since the coating material does not contain a binder, the oral pouch product can provide taste and flavor to the user more effectively.

[0068] According to one embodiment of the present invention, the sugar alcohol-based fiber may have a fineness of 0.1 denier or more and 5 denier or less, and a diameter of 0.1 μm or more and 10 μm or less. Specifically, the fineness of the sugar alcohol-based fiber may be 0.2 denier or more and 4.5 denier or less, 0.4 denier or more and 4 denier or less, 0.6 denier or more and 3.5 denier or less, 0.8 denier or more and 3 denier or less, 1 denier or more and 2 denier or less, 0.1 denier or more and 1 denier or less, 0.5 denier or more and 0.8 denier or less, or 3 denier or more and 5 denier or less. In addition, the diameter of the sugar alcohol-based fiber may be 0.2 μm or more and 8 μm or less, 0.4 μm or more and 6 μm or less, 0.6 μm or more and 4 μm or less, 0.8 μm or more and 2 μm or less, 0.1 μm or more and 2 μm or less, 0.5 μm or more and 1 μm or less, or 5 μm or more and 10 μm or less. When the fineness and diameter of the sugar alcohol-based fiber are within the aforementioned ranges, the coating material can provide a soft tactile sensation to the user at the beginning of use of the oral pouch product, thereby improving user satisfaction. Furthermore, by adjusting the fineness and diameter of the sugar alcohol-based fiber to the aforementioned ranges, the coating material can be stably formed on the packaging material, and excellent taste and flavor can be easily realized.

[0069] According to one embodiment of the present invention, the sugar alcohol-based compound may include at least one of a first sugar alcohol-based compound having a water solubility at 25°C of 10 g / 100g or more and 50 g / 100g or less, and a second sugar alcohol-based compound having a water solubility at 25°C of more than 50 g / 100g and 100 g / 100g or less. Specifically, the water solubility at 25°C of the first sugar alcohol-based compound may be 20 g / 100g or more and 40 g / 100g or less, 25 g / 100g or more and 35 g / 100g or less, 10 g / 100g or more and 35 g / 100g or less, or 35 g / 100g or more and 45 g / 100g or less. In addition, the water solubility of the second sugar alcohol compound at 25°C may be 55 g / 100g or more and 90 g / 100g or less, 65 g / 100g or more and 80 g / 100g or less, 60 g / 100g or more and 75 g / 100g or less, or 70 g / 100g or more and 90 g / 100g or less.

[0070] According to one embodiment of the present invention, the first sugar alcohol compound may include at least one of erythritol and mannitol. In this case, the water solubility of erythritol at 25°C is about 37 g / 100g, and the water solubility of mannitol at 25°C is about 20 g / 100g. Meanwhile, the type of the first sugar alcohol compound is not limited thereto and may include a sugar alcohol compound that satisfies the aforementioned water solubility range.

[0071] In addition, the second sugar alcohol compound may include at least one of maltitol, xylitol, and sorbitol. At this time, the water solubility of maltitol at 25°C is about 60 g / 100g, the water solubility of xylitol at 25°C is about 64 g / 100g, and the water solubility of sorbitol at 25°C is about 60 g / 100g. Meanwhile, the type of the second sugar alcohol compound is not limited thereto and may include a sugar alcohol compound that satisfies the aforementioned water solubility range.

[0072] According to one embodiment of the present invention, the sugar alcohol-based compound comprises the first sugar alcohol-based compound and the second sugar alcohol-based compound, and the weight ratio of the first sugar alcohol-based compound to the second sugar alcohol-based compound may be 1:0.5 to 1:2. That is, the coating material may be formed from a sugar alcohol-based fiber comprising the first sugar alcohol-based compound and the second sugar alcohol-based compound. At this time, the weight ratio of the first sugar alcohol-based compound to the second sugar alcohol-based compound may be 1:0.8 to 1:1.8, 1:1 to 1:1.5, 1:0.5 to 1:1.3, 1:0.7 to 1:1.1, 1:1.4 to 1:2, or 1:1.6 to 1:8. By mixing and using a first sugar alcohol compound and a second sugar alcohol compound with different water solubility, a wider variety of aromas and flavors can be achieved, and the dissolution time of the coating material can be easily controlled. This offers the advantage of allowing users to set a wider range of usage completion times.

[0073] According to one embodiment of the present invention, the coating material may include an inner coating layer provided in contact with the outer surface of the packaging material; and an outer coating layer provided on the inner coating layer. The outer coating layer may primarily serve to provide taste and flavor to the user. Meanwhile, the inner coating layer may primarily serve to notify the user that the time to finish use is approaching. In the case of sugar alcohol-based compounds, the taste and flavor perceived by the user may differ depending on the type. Accordingly, as the coating material is provided in two layers, the user can perceive a change in taste and flavor as the inner coating layer begins to dissolve after the outer coating layer has completely dissolved. Accordingly, the user can perceive that the time to finish use is approaching in stages, thereby enabling more efficient smoking.

[0074] According to one embodiment of the present invention, the outer coating layer comprises a first sugar alcohol-based fiber, and the inner coating layer comprises a second sugar alcohol-based fiber. The first sugar alcohol-based fiber comprises a first sugar alcohol-based compound having a water solubility at 25°C of 10 g / 100g or more and 50 g / 100g or less. The second sugar alcohol-based fiber may comprise a second sugar alcohol-based compound having a water solubility at 25°C of more than 50 g / 100g and 100 g / 100g or less.

[0075] That is, the outer coating layer may contain sugar alcohol-based fibers with relatively low water solubility, and the inner coating layer may contain sugar alcohol-based fibers with relatively high water solubility. As described above, the outer coating layer is primarily configured to provide taste and flavor to the user, so it dissolves more slowly to continuously provide taste and flavor to the user during the smoking process. Meanwhile, the inner coating layer is primarily configured to alert the user to the completion time of use, so it dissolves more quickly to allow the user to perceive a sudden difference in taste, flavor, and texture, thereby enabling the smoking process to be completed effectively. Through this, the sensation of a foreign object in the throat, gastrointestinal burden, or nausea that may occur from prolonged use of the oral pouch product can be effectively prevented.

[0076] According to one embodiment of the present invention, the ratio of the fineness of the first sugar alcohol-based fiber and the second sugar alcohol-based fiber may be 1:0.3 to 1:0.6. Additionally, the ratio of the diameter of the first sugar alcohol-based fiber and the second sugar alcohol-based fiber may be 1:0.3 to 1:0.6. When the ratio of the fineness and diameter of the first sugar alcohol-based fiber and the second sugar alcohol-based fiber satisfies the aforementioned ranges, the user can effectively enjoy the taste and flavor while also easily recognizing that the time for use is approaching.

[0077] According to one embodiment of the present invention, the ratio of the thickness of the outer coating layer to the thickness of the inner coating layer may be 1:0.3 to 1:0.6. When the ratio of the thickness of the outer coating layer to the thickness of the inner coating layer satisfies the aforementioned range, the user can effectively enjoy the taste and flavor while also easily recognizing that the usage time is approaching. At this time, the thickness of the outer coating layer may be 5 μm or more and 100 μm or less, and the thickness of the inner coating layer may be 5 μm or more and 100 μm or less.

[0078]

[0079] One embodiment of the present invention provides a method for manufacturing an oral pouch product comprising: embedding a filler containing an active ingredient in an internal cavity of a packaging material; sealing at least a portion of the periphery of the packaging material; and forming a coating material containing a sugar alcohol-based fiber on at least a portion of the outer surface of the packaging material before or after sealing, wherein the sugar alcohol-based fiber comprises a sugar alcohol-based compound having a water solubility of 10 g / 100g or more and 100 g / 100g or less at 25°C.

[0080] A manufacturing method according to one embodiment of the present invention can easily manufacture an oral pouch product that can provide various flavors to the user and allows the user to easily recognize the usage time through changes in flavor during use.

[0081] The manufacturing method according to the present embodiment may be a method for manufacturing an oral pouch product according to the aforementioned embodiment. Accordingly, the packaging material, filler, coating material, coating liquid, sugar alcohol-based fiber, and sugar alcohol-based compound in the manufacturing method according to the present embodiment may be the same as the packaging material, filler, coating material, coating liquid, sugar alcohol-based fiber, and sugar alcohol-based compound in the oral pouch product according to the aforementioned embodiment.

[0082] According to one embodiment of the present invention, after encapsulating a filler in an internal cavity of a packaging material, a coating material may be formed on the surface of the packaging material. Additionally, a filler may be encapsulated in an internal cavity of the packaging material where the coating material is formed on the surface.

[0083] According to one embodiment of the present invention, the step of forming the coating material may involve forming the sugar alcohol-based fiber on the packaging material by melt-spinning the sugar alcohol-based compound using a melt-blown method. Any device used in the industry for the melt-blown method may be used without limitation. Furthermore, it is obvious that depending on the type of sugar alcohol-based compound, the melt-blown process may be performed under conditions where the sugar alcohol-based compound can be melted and spun.

[0084] According to one embodiment of the present invention, the step of forming the coating material may include the step of melt-spinning a coating raw material comprising the first sugar alcohol-based compound and the second sugar alcohol-based compound by a melt-blown method. Through this, a coating material can be formed in which a sugar alcohol-based fiber comprising the first sugar alcohol-based compound and the second sugar alcohol-based compound is provided in a web form.

[0085] According to one embodiment of the present invention, the step of forming the coating material may include: a step of forming an inner coating layer by meltblown spinning a second coating raw material containing the second sugar alcohol-based compound onto the outer surface of the packaging material; and a step of forming an outer coating layer by meltblown spinning a first coating raw material containing the first sugar alcohol-based compound onto the inner coating layer. Through this, the inner coating layer containing the second sugar alcohol-based fiber and the outer coating layer containing the first sugar alcohol-based fiber can be sequentially formed on the outer surface of the packaging material.

[0086]

[0087] Hereinafter, the present invention will be described in detail with reference to examples to specifically explain the invention. However, the embodiments according to the present invention may be modified in various different forms, and the scope of the present invention is not to be interpreted as being limited to the embodiments described below. The embodiments of this specification are provided to more completely explain the present invention to those with average knowledge in the art.

[0088]

[0089] Examples

[0090] As a packaging material, a nonwoven fabric was prepared using staple fibers having a fineness of about 5 denier and a diameter of about 15 μm. At this time, the thickness of the nonwoven fabric was about 150 μm, and the basis weight was about 35 g / m². A cellulose-based filler containing about 3 wt% of nicotine tartrate as an active ingredient was prepared.

[0091] As a first sugar alcohol compound, erythritol was prepared, which has a water solubility of about 37 g / 100g at 25°C and a very strong refreshing sensation. As a second sugar alcohol compound, maltitol was prepared, which has a water solubility of about 60 g / 100g at 25°C and almost no refreshing sensation.

[0092]

[0093] Example 1

[0094] The prepared packaging material was folded in half to embed approximately 0.4 g of filler, and three sides were heat-fused to seal it. Subsequently, a coating material containing erythritol was melt-blown spun to form a coating material over the entire outer surface of the packaging material to manufacture an oral pouch product.

[0095]

[0096] At this time, the fineness of the melt-blown sugar alcohol fiber was about 0.8 denier, and the diameter was about 1 μm. In addition, the thickness of the coating material was about 100 μm.

[0097]

[0098] Example 2

[0099] A mixed coating raw material was prepared containing erythritol, a first sugar alcohol compound, and maltitol, a second sugar alcohol compound. At this time, the weight ratio of erythritol to maltitol was 1:1.8.

[0100]

[0101] Subsequently, an oral pouch product was manufactured using the same method as in Example 1 above. At this time, the fineness of the melt-blown spun sugar alcohol-based fiber was about 0.8 denier, and the diameter was about 1 μm. In addition, the thickness of the coating material was about 100 μm.

[0102]

[0103] Example 3

[0104] The packaging material prepared above was folded in half, about 0.4 g of filling material was inserted, and three sides were heat-sealed to seal it.

[0105] A first coating raw material containing erythritol, a first sugar alcohol compound, and a second coating raw material containing maltitol, a second sugar alcohol compound were prepared.

[0106]

[0107] Subsequently, a second coating material was melt-blown spun to form an inner coating layer over the entire outer surface of the packaging material. Then, a first coating material was melt-blown spun to form an outer coating layer over the entire outer surface of the inner coating layer.

[0108] At this time, the second sugar alcohol-based fiber formed by melt-blowing the second coating raw material had a fineness of about 0.5 denier and a diameter of about 0.6 μm. In addition, the thickness of the inner coating material was about 60 μm. The first sugar alcohol-based fiber formed by melt-blowing the first coating raw material had a fineness of about 0.8 denier and a diameter of about 1 μm. In addition, the thickness of the outer coating material was about 100 μm.

[0109]

[0110] Comparative Example 1

[0111] The packaging material prepared above was folded in half, about 0.4 g of filling material was inserted, and three sides were heat-sealed to seal it, thereby manufacturing an oral pouch product.

[0112]

[0113] Comparative Example 2

[0114] The packaging material prepared above was folded in half to embed approximately 0.4 g of filler, and the three sides were heat-sealed to seal it. Subsequently, a molten erythritol solution was applied to the entire packaging material and dried to form a coating material, thereby manufacturing an oral pouch product. At this time, the thickness of the coating material was approximately 100 μm.

[0115]

[0116] Experimental Example

[0117] Perceived usage time evaluation

[0118] A blind test was conducted on 13 evaluation panel members with more than 5 years of experience in smoking and using oral pouch products. The oral pouch products of the examples and comparative examples were inserted between the upper lip and gums on the left side, and the time from insertion until the point at which use was deemed finished based on the sensation of the outer surface texture of the packaging material and the change in taste was measured and calculated as an average, which is shown in Table 1 below.

[0119] Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Usage time (min) 27.3 28.9 23.7 41.8 36.1

[0120]

[0121] Referring to Table 1, it was confirmed that the oral pouch products of the examples were used up within an appropriate time.

[0122] On the other hand, in the case of Comparative Example 1, since no coating material was provided, no change in texture or taste was perceived, and it was confirmed that the usage time was the longest. In addition, in the case of Comparative Example 2, compared to the cases using Examples 1 to 3, it was confirmed that the usage time increased because the point at which the change in texture and taste was perceived was delayed.

[0123] Meanwhile, 12 out of 13 panel members answered that, compared to Examples 1 and 2, in the case of Example 3, they could more easily perceive that the usage time was nearing its end as the refreshing sensation disappeared, even though the texture remained soft after the strong refreshing sensation of erythritol was felt. Accordingly, it can be seen that by configuring the coating material with a multi-layer structure, users can be made to recognize the end of use through a more easy and rapid change in taste, and can be encouraged to stop using the product after an appropriate amount of time has elapsed.

[0124]

[0125] Smoking sensory evaluation

[0126] A blind test was conducted on 13 evaluation panel members with more than 5 years of experience using smoking and oral pouch products. Scores were assigned according to a 5-point scale, and the results are shown in Table 2 below.

[0127] Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Smoking Satisfaction 3.7 7 3.7 9 3.7 5 3.6 9 3.25 Flavor 4.0 7 4.2 1 4.3 7 1.7 9 4.13 Texture 3.9 3 3.8 7 4.0 1 2.8 7 3.75 Overall Tobacco Taste 3.7 6 3.8 3 3.8 1 3.5 5 3.24 Discomfort 2.8 4 2.9 8 2.5 7 4.3 3 4.08
