Description

The present invention relates to flavored products intended for human use. The products are configured for oral use and deliver substances such as flavors and / or active ingredients during use. Such products may include tobacco or a tobacco-derived product, or may be non-tobacco alternatives. Background of the Invention Tobacco can be enjoyed in a so-called smokeless form. The most popular smokeless tobacco products are used by inserting some form of processed tobacco or tobacco-containing formulation into the user's mouth. Conventional formats of these smokeless tobacco products include moist snuff, snus, and chewing tobacco, which are typically composed almost entirely of particulate, granulated, or shredded tobacco and can be portioned by the user or presented in individual servings, such as in single-use pouches or sachets. Other traditional forms of smokeless products include compressed or pelletized forms, such as plugs, lozenges, or pellets. Alternative product formats are also known, such as tobacco-containing gums and blends of tobacco with other plant materials.See, e.g., the types of smokeless tobacco formulations, ingredients, and processing methodologies disclosed in U.S. Patents 1,376,586 to Schwartz; 4,513,756 to Pittman et al; 4,528,993 to Sensabaugh, Jr. et al; 4,624,269 to Story et al; 4,991,599 to Tibbetts; 4,987,907 to Townsend; 5,092,352 to Sprinkle, III et al; 5,387,416 to White et al; 6,668,839 to Williams; 6,834,654 to Williams; 6,953,040 to Atchley et al; 7,032,601 to Atchley et al; and 7,694,686 to Atchley et al. in U.S. patent applications 2004 / 0020503 to Williams; 2005 / 0115580 to Quinter et al.; 2006 / 0191548 to Strickland et al.; 2007 / 0062549 to Holton, Jr. et al.; 2007 / 0186941 to Holton, Jr.et al; 2007 / 0186942 to Strickland et al; 2008 / 0029110 to Dube et al; 2008 / 0029116 to Robinson et al; 2008 / 0173317 to Robinson et al; 2008 / 0209586 to Neilsen et al; 2009 / 0065013 to Essen et al; and 2010 / 0282267 to Atchley, as well as in W02004 / 095959 to Amarp et al, each of which is incorporated herein by reference.

Various types of packaged and unpackaged products comprising one or more fleece materials as described herein and configured for oral use are described in more detail below. LQPoen / zznz / q / YiAi - 9 Products in bag Pouch products typically include a water-permeable outer pouch and a composition positioned within the water-permeable outer pouch. The composition positioned within the pouch may be any composition containing a water-soluble component capable of being released through the water-permeable pouch, such as tea or coffee materials (e.g., in the context of a beverage pouch adapted for brewing or steeping) or compositions adapted for oral use (e.g., tobacco-derived products such as snus or nicotine replacement therapy products). In certain embodiments, the composition within the pouch cavity may comprise at least one of particulate tobacco materials, nicotine, particulate non-tobacco material (e.g., MCC) that has been treated to contain nicotine and / or flavors, and fibrous plant material (e.g., beet root fiber) treated to contain a tobacco extract. Various types of pouch materials and manufacturing techniques are discussed in more detail below. Generally, pouch products include a substrate material, which may be in the form of a powdered or granular composition adapted for oral use (e.g., a tobacco-containing composition, a nicotine-containing pharmaceutical composition, and / or a non-tobacco-containing composition) disposed within a moisture-permeable container. That is, the composition adapted for oral use may be contained within a container, such as a pouch or bag, such as the type commonly used for the manufacture of snus-type products (e.g., a sealed, moisture-permeable pouch sometimes referred to as a pouch). A representative moisture-permeable bag may preferably be made of a fleece-type material. For example, various fleece materials such as those described herein, such as those that advantageously retain releasable components therein, can be used as the moisture-permeable bag material described herein.

The plurality of dots represents the releasable component 106 retained throughout the bag-shaped fleece material 102.The orientation, size and type of bag material, as well as the type and nature of the substrate material contained therein, are not construed as limiting the bag. LQPQCn / ZZnZ / q / YIAI - 10 Pouchless Products (not packaged) Advantageously, in some embodiments of the present invention, oral products comprising a fleece, as provided herein, are provided in a form other than the pouch configuration described above. Such products are referred to herein as having an unpackaged configuration. An unpackaged product, as referred to herein, refers to an oral product configured for oral use comprising one or more layers of a fleece material (e.g., a material as described herein), such that it is substantially devoid of an interior cavity and does not comprise an additional substrate material as is known to be incorporated into typical pouch products as described in the relevant art.For example, the oral products described herein may be formed solely from multiple layers of fleece material sealed together after the application of heat and / or pressure. Methods for preparing such oral products are described in more detail below. The mix / construction of such unpackaged products may be varied. For example, Figure 2 shows an unpackaged product configured for oral use in accordance with an exemplary embodiment of the present invention that will be described later. Referring to Figure 2, the product 200 includes a fleece material 202 comprising fibers (not shown) and a releasable component 204, as represented by the plurality of dots along the fleece material 202. The plurality of dots represents that the releasable component 204 is retained throughout the fleece material 202. For example, in some embodiments according to the present invention, the releasable component may be embedded within the fleece material, adsorbed or adsorbed onto a surface of the fleece material, or contained within a bulk of the fleece material, either directly or in the form of a plurality of microcapsules.Various configurations and types of fleece materials and lead components, as described below, may be suitable for providing the desired delivery of flavoring agents and / or active ingredients retained within such fleece materials. The orientation, size, and configuration of the oral product illustrated in Figure 2 should not be construed as a limitation thereof. Fleece material As mentioned above, the pouched and unpouched products provided herein comprise at least one fleece material. These fleece materials may be in the form of a fleece fabric material, such as in the form of a woven or nonwoven fabric comprising a plurality of fibers. In some embodiments, the fleece fabric material may be configured to have improved characteristics with respect to flavor and / or the release of active ingredients and / or flavoring agents to a user of products comprising such fleece materials. LQPQCn / ZZnZ / q / YILY - 11 interior. As mentioned above, the bagged products provided herein comprise at least one fleece material. The fleece materials referred to herein may be in the form of a fleece fabric material, such as in the form of a woven or non-woven fabric comprising a plurality of fibers. As used herein, the term "fiber" is defined as a basic element of textiles. Fibers are often in the form of a rope-like element. As used herein, the term "fiber" includes fibers, filaments, continuous filaments, staple fibers, and the like. The term "nonwoven" is used herein to refer to fibrous materials, fabrics, mats, batts, or sheets in which the fibers are aligned in an indefinite or random orientation. Nonwoven fibers initially appear as unbonded fibers or filaments. An important step in the manufacture of nonwovens is joining the individual fibers or filaments. The manner in which the fibers or filaments are joined can vary and includes thermal, mechanical, and chemical techniques that are selected in part based on the desired characteristics of the final product, as explained in more detail below. In some embodiments, the fleece materials of the present invention may be configured to have improved characteristics with respect to organoleptic properties and / or dissolution profile. A fleece material according to the present invention may be formed from various types of fibers (e.g., conventional cellulosic fibers (such as viscose fibers, regenerated cellulose fibers, cellulose fibers and wood pulps), cotton fibers, wool fibers, other natural fibers, polymeric / synthetic type fibers and combinations thereof) capable of being formed into a traditional fleece fabric or other traditional bag materials. For example, the fleece materials may be provided in the form of a woven or non-woven fabric. Suitable types of fleece materials, for example, are described in U.S. Pat. No. 8,931.493 to Sebastian et al.; in patent application US 2016 / 0000140 to Sebastian et al.; and US 2016 / 0073689 to Sebastian et al.; which are incorporated herein by reference. Methods of forming nonwoven fabrics for natural and synthetic fibers may include drylaid, airlaid, and wetlaid methods. In some embodiments, the nonwoven fabric may be formed using a spunmelt process, including both spunbond and meltblown processes, such processes typically being understood to involve the melting, extrusion, collection, and bonding of thermoplastic polymeric materials to form a nonwoven fiber. The meltblown technique is known in the art and is discussed in several patents, for example, in U.S. Patents 3,849,241 to Butin, 3,987,185 to Buntin et al., 3,972,759 to Buntin, and 4,622,259 to McAmish et al., each of which is incorporated herein by reference in its entirety.General spunbonding processes are described, for example, in U.S. patents 4,340,563 to Appel et al., 3,692,618 to Dorschner. LQPQCn / ZZnZ / q / YIAI - 12et al, 3,802,817 to Matsuki et al, 3,338,992 and 3,341,394 to Kinney, 3,502,763 to Hartmann, and 303,542,615 to Debo et al, which are incorporated herein by reference. In some embodiments, the fibers within the fleece material may include, but are not limited to, a polymer selected from the group consisting of polyglycolic acid, polylactic acid, polyhydroxyalkanoates, polycaprolactone, polybutylene succinate, polybutylene adipate succinate, and copolymers thereof. In some embodiments, the fibers within the fleece material may be selected from the groups consisting of cellulose fibers, viscose fibers, regenerated cellulose fibers, other wood fibers, and the like. Fleece materials can have different thicknesses, porosities, and other parameters. For example, the fleece material can be formed such that the fiber orientation and porosity of the fleece material are modified to achieve the desired release characteristics of the releasable component it contains. In some embodiments, a coating or other additive can be added to the fibers before forming the fleece material. For example, in some embodiments, a coating of an acrylic polymer can be used to act as a binder for the fibers in the nonwoven fabric and allow for heat bonding / sealing of the fleece material. Releasable component A releasable component, as used herein, refers to any material that is retained by the fleece material and can be released therefrom in response to a certain stimulus, for example, upon contact with the oral cavity of a user or upon application of a certain minimal mechanical force to the product by the user, for example, by chewing or working the product in the oral cavity. The release component may preferably be adapted or configured to absorb, adsorb, or otherwise become directly entrained / incorporated within the porous structure of the fleece material. In this manner, the releasable component may be retained with a desired level of stability and / or may be configured for controlled release from the naturally porous structure of the fleece material.Furthermore, the releasable component may be adapted to enhance one or more sensory characteristics of the product, such as flavor, mouthfeel, moistness, coolness / warmth, and / or fragrance. A wide variety of releasable components may be used. In some embodiments, a plurality of releasable components may be used. In some embodiments, the different releasable components may be adapted or configured to be preferentially retained within the pores of the fleece materials. The pores within the fleece material may be altered during production thereof in order to deliver an oral product with the desired release profile of the releasable components thereof. In some embodiments, the products are provided with multiple layers of fleece materials, and said individual layers may comprise the same or other releasable components associated therewith. LQRQCn / ZZnZ / q / YIAI - 13In some embodiments, the releasable component may be encapsulated before being impregnated within the fleece material or otherwise provided in a surface coating applied to the fleece materials. For example, in some embodiments, the releasable component may be provided in the form of a plurality of microcapsules that are contained within the mass of the fleece material. As used herein, contained within the mass of the fleece material means that the plurality of capsules are positioned substantially within one or more layers of the fleece material, either individually or in combination.For example, the plurality of capsules may be contained within the mass of the fleece material if at least 70% of the surface area of ​​the capsules is retained within peripheral edges of the fleece material, at least 80% of the surface area of ​​the capsules is retained within peripheral edges of the fleece material, at least 90% of the surface area of ​​the capsules is retained within peripheral edges of the fleece material, or at least 95% of the surface area of ​​the capsules is retained within peripheral edges of the fleece material. In some embodiments, the exposed surface area may be measured to define the amount of material embedded / absorbed / contained therein, e.g., to distinguish such material from material in the form of surface flavoring or the like. An encapsulated releasable component is generally contained within an outer shell or coating. The outer shell or coating of the plurality of such capsules serves as a barrier between the releasable component and a user's oral cavity. Typically, such an outer shell or coating is designed to be temporary; that is, the barrier is designed to cease serving as a barrier and thus release the releasable component under certain conditions of use of the product. In many embodiments, the releasable component is released when the outer shell undergoes some form of physical destruction, rupture, or other loss of physical integrity (e.g., by disintegration, softening, crushing, application of pressure, or the like), thereby altering the sensory or functional properties of the product during use.Thus, for example, a plurality of capsules may be incorporated within the fleece material, and during use, contact of the capsules with moisture present in the user's mouth may cause the capsules to soften, lose their physical integrity, and release the additive into the user's mouth. In some embodiments, the capsules may be intentionally crushed upon application of pressure, i.e., by being chewed or worked by a user of the product, such that the releasable component retained in the capsules is released within the fleece material. Such release of the releasable component may alter or enhance the flavor or other sensory characteristics of the product, extend the period of time the user may enjoy the product, or provide other functional advantages. Examples of breakable capsules that may be provided in smokeless tobacco products, and which in some embodiments may be incorporated or adapted for use within the disclosed products, are described in detail.

LQPQCn / ZZnZ / q / YILY -25In some embodiments, the composition is substantially free of any API. Substantially free of any API means that the composition does not contain, and specifically excludes, the presence of any API as defined herein, such as any therapeutic agent approved by the Food and Drug Administration (FDA) intended to treat any medical condition. Flavoring Agents In some embodiments, the releasable component may comprise a flavoring agent. For example, the releasable component may include a single flavoring agent or a plurality of flavoring agents. If desired, one or more flavoring agents may be embedded in the fleece material, absorbed or adsorbed onto at least one surface of the fleece material, or contained within the bulk of the fleece material. As used herein, a flavoring agent or flavoring agent is any flavorful or savory substance capable of altering the sensory characteristics associated with the oral product. Some examples of sensory characteristics that can be modified by the flavoring agent are taste, mouthfeel, moistness, coolness / warmth, and / or fragrance / aroma. Flavoring agents can be natural or synthetic, and the character of the flavors imparted by them can be described, without limitation, as fresh, sweet, grassy, ​​confectionery, floral, fruity, or spicy.Non-limiting examples of flavoring agents that may be used as releasable components herein (e.g., when retained within the fleece material) may include vanilla, coffee, chocolate / cocoa, cream, peppermint, spearmint, menthol, peppermint, wintergreen, eucalyptus, lavender, cardamom, nutmeg, cinnamon, clove, cascarilla, sandalwood, honey, jasmine, ginger, anise, sage, licorice, lemon, orange, apple, peach, lime, cherry, strawberry, terpenes, trigeminal sinuses, and any combination thereof. See also, Leffingwell et al., Tobacco Flavoring for Smoking Products, R.J. Reynolds Tobacco Company (1972), which is incorporated herein by reference. Flavorings may also include components that are considered humectant, cooling, or softening agents, such as eucalyptus.These flavors may be provided alone or in a composition, and may be employed as concentrates or flavor packets (e.g., spearmint and menthol; orange and cinnamon; lime, pineapple, and the like). Representative types of components are also disclosed in U.S. Patent 5,387,416 to White et al.; U.S. patent application 2005 / 0244521 to Strickland et al.; and WO 05 / 041699 to Quinter et al., each of which is incorporated herein by reference. In some instances, the flavoring agent may be provided in spray-dried or liquid form. The flavoring agent may be a volatile flavoring component. As used herein, volatile refers to a chemical that readily forms a vapor at room temperature (i.e., a chemical that has a high vapor pressure at a LQPQCn / ZZnZ / q / YIAI -26temperature determined relative to a non-volatile substance). Typically, a volatile flavor component has a molecular weight of less than about 400 Da, and often includes at least one carbon-carbon double bond, one carbon-oxygen double bond, or both. In one embodiment, the at least one volatile flavor component comprises one or more alcohols, aldehydes, flavor hydrocarbons, ketones, esters, terpenes, terpenoids, or a combination thereof.

In one embodiment, the minimum volatile flavor component comprises ethyl vanillin. The amount of flavoring agent used in the releasable component may vary, but is typically up to 10% by weight, and certain embodiments are characterized by a flavoring agent content of at least 0.1% by weight, such as 0.5 to 10%, 1 to 5%, or 2 to 4% by weight, based on the total weight of the oral product (not including the fleece material). Manufacturing methods for unpackaged products Some aspects of the present invention provide methods of forming fleece materials containing releasable components and methods of forming oral products comprising such releasable component-containing fleece materials (e.g., such as the oral products described herein), e.g., as illustrated in Figure 3. As depicted in Figure 3, methods of forming fleece materials containing releasable components according to the present invention may comprise forming a fleece material comprising a plurality of fibers, as depicted in step 210; and charging the fleece material with a releasable component to provide a fleece material containing releasable components, as depicted in step 230.It should be noted that the above steps are interchangeable, and therefore the fleece material can be filled with the lead component before, during, or after forming the fleece material. For example, the lead component can be impregnated into an already formed fleece fabric, or microcapsules of the lead component can be combined with a fiber slurry before forming the fleece fabric. As previously noted, various types of fibers (e.g., cellulosic fibers, etc.) can be used. LQPoen / zznz / q / YiAi - 27 other polymer / synthetic fibers) to form the fleece materials according to the present invention. Furthermore, the fleece materials may be formed using any method for forming a woven or nonwoven fabric as detailed above. As indicated above, various types and combinations of fibers and releasable components may be incorporated into the fleece materials prepared according to the methods described herein, and therefore, such methods, as described below with respect to one embodiment, should not be construed as limiting in any way. In some embodiments, the fleece material may optionally be extruded, as depicted in step 220, prior to loading the fleece material with a releasable component in step 230. The fleece materials may be extruded by any means commonly known in the art. In some embodiments, the fleece materials may be extruded before, during, or after incorporation of the releasable component. As indicated above, the fleece materials of the present invention may be formed using a spinning or melt process, for example, including both spinning and melt-blown processes, wherein it is understood that such processes typically involve melting, extruding, collecting, and joining fibrous materials to form a nonwoven fibrous web.Typically, extrusion parameters may vary, for example, extrusion parameters may be modified depending on the types of materials or components used in the fleece materials. As seen in Figure 3, a method of preparing an oral product incorporating steps 210 and 230 is also provided in one embodiment of the present invention. For example, an oral product may be prepared by providing a continuous supply of a fleece material 240 containing releasable components, wherein said fleece material has been prepared according to the methods described in operations 210 and 230. The fleece material containing releasable components may then be subdivided into discrete portions, as depicted in operation 250; and two or more discrete portions may be sealed together in operation 260 (e.g., by the application of heat and / or pressure) to provide a product configured for oral use.The discrete portions, as described herein, are essentially cut segments of a continuous fleece material, as described herein, that have been cut to desired dimensions; for example, the length and width of the desired oral product. Furthermore, these discrete portions may be superimposed on one another prior to the sealing step to form an oral product essentially containing multiple layers of the fleece material containing releasable components. It is noted that such discrete portions may comprise portions of the same fleece material or different fleece materials (e.g., allowing for lamination of fleece layers comprising the same releasable component and / or lamination of fleece layers with different releasable components, etc.). LQPQCn / ZZnZ / q / YIAI - 28include, for example, one or more layers comprising a flavoring and one or more layers comprising an active ingredient). In some embodiments, the two or more discrete portions may be sealed together by applying pressure and / or heat to the layered portions. In some embodiments, the sealing may be applied to the entire layered portions, or alternatively, the layered portions may be sealed only at specific portions thereof. For example, the layers of fleece material may be sealed only along the periphery of the discrete portions, such that the internal cross-section of the product is more voluminous compared to the sealed peripheral edges. This configuration may provide a mouthfeel and other organoleptic properties that mimic a traditional pouched product when placed in the mouth of a user of the product. The number of discrete portions of fleece materials that may be superimposed before sealing said portions to form an oral product may vary. For example, in some embodiments, the number of individual layers of fleece material in the product may be in the range of about 1 to about 20, or about 4 to about 16, or about 8 to about 12. In some embodiments, the number of individual layers of fleece material in the product may be at least about 3, at least about 6, at least about 9, at least about 12, at least about 15, or at least about 18. Products configured for oral use As mentioned above, several types of oral products are described that may incorporate a releasable fleece-containing component, for example, pouched products and unpouched products. Unpackaged products may consist essentially of one or more layers of fleece containing the releasable component. The layers are advantageously sealed together as described above to provide an unpackaged fleece product comprising one or both of the active ingredients and a flavoring agent. As described above, various types of fleece materials and releasable components are provided herein, and such materials and various combinations thereof are suitable for use in the unpackaged products described herein. Pouch products typically include a water-permeable outer pouch formed by one or more layers of fleece containing releasable components and a composition positioned within the water-permeable outer pouch. The composition is typically in the form of a substrate material, as mentioned above, which is inserted into a defined cavity within the water-permeable outer pouch to provide a pouch product comprising one or both of the active ingredients and a flavoring agent. LQRQCn / ZZnZ / q / YIAI -29An aspect of the present invention provides pouch products configured for oral use, wherein said pouch products may comprise a fleece material in the form of a pouch and containing a substrate material, the fleece material comprising fibers and a releasable component. As indicated above, various types of fleece materials and releasable components are provided herein, and such materials are suitable for use in the pouch products as described herein. Advantageously, the use of such fleece materials in combination with a substrate material may, in some embodiments, provide extended release of one or more active ingredients and / or flavoring agents.For example, the releasable component (e.g., the active ingredient and / or flavoring agent) may be delivered to a user of the product within a relatively short period of time (e.g., substantially immediately) upon insertion of the product into the user's oral cavity, whereas the components of the substrate material within the pouch (which may also comprise active ingredients and / or flavoring agents, or which may comprise only other types of components, e.g., as described below) may be released more slowly as they are allowed to permeate through the fleece material over time during use. The combinations of releasable components and substrate materials within pouch products may vary. Advantageously, such combinations may vary depending on the desired release profile and the characteristics of the final product. For example, in some embodiments, a pouch product may comprise an active ingredient as a releasable component in the fleece and a flavoring agent provided as a component of the substrate material (e.g., such that the product provides immediate release of the active ingredient and delayed release of the flavoring material). In some embodiments, a pouch product may comprise a flavoring agent as a releasable component in the fleece and an active ingredient provided as a component of the substrate material (e.g., such that the product provides immediate release of the flavoring material and delayed release of the active ingredient).In some embodiments, a pouch product may comprise both a flavoring agent and an active ingredient in the substrate material and an additional flavoring agent as a releasable component in the fleece (e.g., such that the product provides immediate release of the flavoring agent in the fleece and delayed release of the active ingredient and the additional flavoring agent, which may optionally be the same or different than the flavor provided in the fleece). It should be noted that the above examples should not be construed as limiting and that any combination of ingredients may be provided as components in the releasable component and the substrate material to provide the desired release profile in the final pouch product. For example, the active ingredients and flavoring agents, in particular, may advantageously be provided as the releasable component and / or material. LQPQCn / ZZnZ / q / YILY -30 substrate, and any possible combination thereof, in order to alter the release profile of these components to a user of the bagged product to provide controlled release of one or more flavors and one or more active ingredients. In some embodiments, the pouch products of the present invention may include at least one active ingredient in the fleece material (e.g., in the form of a releasable component), in the substrate material, or both. For example, if desired, one or more active ingredients may be embedded within the fleece material as described above, and / or one or more active ingredients may be otherwise retained in the substrate material, such as by being bound to additional filler or being present in a unitary form (e.g., active ingredients in pellet form). In some embodiments, a first active ingredient is provided in the fleece material and a second active ingredient is provided within the substrate material. In these embodiments, the first and second active ingredients may be the same or different. Any active ingredient described herein (e.g., in reference to the releasable component) is suitable for use within the substrate material. For example, in some embodiments, the substrate material may comprise a nicotine component. Typically, the nicotine component (calculated as the free base), when present, is in a concentration of at least 0.001% by weight of the substrate material, such as in a range of about 0.001% to about 10%.In some embodiments, the nicotine component is present at a concentration of about 0.1% w / w to about 10% by weight, such as about 0.1% w / w, about 0.2%, about 0.3%, about 0.4%, about 0.5%, about 0.6%, about 0.7%, about 0.8%, or about 0.9%, to about 1%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, or about 10% by weight, calculated as the free base and based on the total weight of the substrate material.In some embodiments, the nicotine component is present at a concentration of about 0.1% by weight to about 3% by weight, such as about 0.1% by weight to about 2.5%, about 0.1% to about 2.0%, about 0.1% to about 1.5%, or about 0.1% to about 1% by weight, calculated as the free base and based on the total weight of the substrate material. These ranges may also apply to other active ingredients noted herein that may be incorporated into the substrate material. In some embodiments, the pouch products of the present invention may include at least one flavoring agent in the fleece material (e.g., in the form of a releasable component), in the substrate material, or in both. For example, if desired, one or LQPQCn / 77nZ / q / YIAI - 31 More flavoring agents may be embedded within the fleece material as described above, and / or one or more flavoring agents may be otherwise retained in the substrate material, such as by being attached to an additional filler or by being present in a unitary form (e.g., active ingredients in the form of pellets). In some embodiments, a first flavoring agent is provided in the fleece material and a second flavoring agent is provided in the substrate material. In such embodiments, the first and second flavoring agents may be the same or different. Any flavoring agent described herein (e.g., in reference to the releasable component) is suitable for use in the substrate material. The amount of flavoring agent used in the substrate material may vary, but is typically up to 10 weight percent, and certain embodiments are characterized by a flavoring agent content of at least 0.1 weight percent, such as 0.5 to 10 weight percent, 1 to 6 weight percent, or 2 to 5 weight percent, based on the total weight of the substrate material. When the product of the present invention is a pouched product, the pouched product may include other components, for example, associated with the substrate. Such components are not intended to be limiting; rather, several examples of components that may be incorporated into packaged products are provided below. It should be noted that these components are described with specific reference to inclusion within pouched products; however, in some embodiments, it may be possible to incorporate such additional components within a fleece material or otherwise associate such additional components with a fleece material (in addition to the aforementioned releasable components to provide the unpackaged product referred to herein). Filler component The substrate material described herein may include at least one particulate filler component. Such particulate filler components may serve multiple functions, such as improving certain organoleptic properties, such as texture and mouthfeel, improving product cohesiveness or compressibility, and the like. Typically, the filler components are porous particulate materials and are cellulose-based. For example, suitable particulate filler components are any non-tobacco plant material or derivative thereof, including cellulose materials derived from such sources. Examples of suitable non-tobacco cellulosic plant materials include cereal grains (e.g., corn, oats, barley, rye, buckwheat, and the like), sugar beets (e.g., FIBREX® brand filler available from International Fiber Corporation), bran fiber, and mixtures thereof.Non-limiting examples of non-tobacco plant material derivatives include starches (e.g., potato, wheat, rice, corn), natural cellulose, and modified cellulosic materials. Other possible examples include: LQPQCn / 77nZ / q / YIAI -32 particulate fillers include maltodextrin, dextrose, calcium carbonate, calcium phosphate, lactose, mannitol, xylitol, and sorbitol. Combinations of fillers can also be used. In this sense, Starch, as used herein, may refer to pure starch from any source, modified starch, or starch derivatives. Starch is present, usually in granular form, in almost all green plants and in various types of plant tissues and organs (e.g., seeds, leaves, rhizomes, roots, tubers, shoots, fruits, grains, and stems). Starch can vary in composition, as well as in granular shape and size. Often, starch from different sources has different chemical and physical characteristics. A specific starch may be selected for inclusion in the mixture based on the starch material's ability to impart a specific organoleptic property to the composition. Starches derived from a variety of sources may be used. For example, major sources of starch are cereal grains (e.g., rice, wheat, and corn) and root vegetables (e.g., potatoes and cassava).Other examples of starch sources include acorns, arrowroot, arracacha, plantains, barley, beans (e.g., lentils, mung beans, peas, chickpeas), breadfruit, buckwheat, sugarcane, chestnuts, colacasia, katakuri, kudzu, taro, millet, oats, oca, Polynesian arrowroot, sago, sorghum, sweet potato, quinoa, rye, tapioca, taro, tobacco, water chestnuts, and yams. Some starches are modified starches. A modified starch has undergone one or more structural modifications, often designed to alter its properties at high temperatures. Some starches have been developed through genetic modification and are considered genetically modified starches. Other starches are obtained and subsequently modified by chemical, enzymatic or physical means.For example, modified starches can be starches that have been subjected to chemical reactions, such as esterification, etherification, oxidation, depolymerization (thinning) by acid catalysis or oxidation in the presence of a base, bleaching, transglycosylation and depolymerization (e.g., dextrinization in the presence of a catalyst), crosslinking, acetylation, hydroxypropylation, and / or partial hydrolysis. Enzymatic treatment includes subjecting native starches to enzyme isolates or concentrates, microbial enzymes, and / or enzymes native to plant materials, for example, amylase present in corn kernels to modify corn starch. Other starches are modified by heat treatments, such as pregelatinization, dextrinization, and / or cold water swelling processes. Certain modified starches include monostarch phosphate, starch glycerol, starch phosphate esterified with sodium trimetaphosphate, starch phosphate, acetylated starch phosphate, starch acetate esterified with acetic anhydride, starch acetate esterified with vinyl acetate, acetylated starch adipate, acetylated starch glycerol, hydroxypropyl starch, hydroxypropyl starch glycerol, sodium starch octenyl succinate. LQPQCn / ZZnZ / q / YIAI -33In some embodiments, the particulate filler component is a cellulose material or a cellulose derivative. A particularly suitable particulate filler component for use in the products described herein is microcrystalline cellulose (MCC). The MCC may be synthetic or semi-synthetic, or may be obtained entirely from natural celluloses. The MCC may be selected from the group consisting of AVICEL® grades PH-100, PH-102, PH-103, PH-105, PH-112, PH-113, PH-200, PH-300, PH-302, VIVACEL® grades 101, 102, 12, 20, and EMOCEL® grades 50M and 90M, and the like, and mixtures thereof. In one embodiment, the mixture comprises MCC as the particulate filler component. The amount of MCC present in the mixture described here may vary depending on the desired properties. The amount of particulate filler component may vary, but is typically up to about 75 percent of the substrate material by weight, based on the total weight of the substrate material. A typical range of particulate filler material (e.g., MCC) within the substrate material may be from about 10 to about 75 percent by total weight of the mixture, e.g., from about 10, 15, 20, 25, or 30, to about 35, 40, 45, or 50 percent by weight (e.g., from about 20 to 50 percent by weight or from about 25 to 45 percent by weight). In certain embodiments, the amount of particulate filler material is at least 10 percent by weight, such as at least 20 percent, or at least 25 percent, or at least 30 percent, or at least 35 percent, or at least 40 percent, based on the total weight of the substrate material. In one embodiment, the particulate filler component further comprises a cellulose derivative or a combination of such derivatives. In some embodiments, the mixture comprises from about 1 to about 10% of the cellulose derivative by weight, based on the total weight of the mixture, with certain embodiments comprising from about 1 to about 5% by weight of cellulose derivative. In certain embodiments, the cellulose derivative is a cellulose ether (including carboxyalkyl ethers), that is, a cellulose polymer with the hydrogen of one or more hydroxyl groups in the cellulose backbone replaced by an alkyl, hydroxyalkyl, or aryl group. Non-limiting examples of such cellulose derivatives are methylcellulose, hydroxypropylcellulose (HPC), hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose, and carboxymethylcellulose (CMC).In one embodiment, the cellulose derivative is one or more of methylcellulose, HPC, HPMC, hydroxyethylcellulose, and CMC. In one embodiment, the cellulose derivative is HPC. In some embodiments, the mixture comprises about 1 to about 3% HPC by weight, based on the total weight of the substrate material. LQRQCn / ZZnZ / q / YIAI -34Tobacco material In some ways, the substrate material of the product in the bag may include tobacco material. The tobacco material can vary in species, type and shape. Generally, the tobacco material is obtained from a plant grown of the Nicotiana species. Examples of Nicotiana species include N. tabacum, N. rustica, N. alata, N. arentsii, N. excelsior, N. forgetiana, N. glauca, N. glutinosa, N. gossei, N. kawakamii, N. knightiana, N. langsdorffi, N. otophora, N. setchelli, N. sylvestris, N. tomentosa, N. tomentosiformis, N. undulata, N. x sanderae, N. africana, N. amplexicaulis, N. benavidesii, N. bonariensis, N. debneyi, N. longiflora, N. maritina, N. megalosiphon, N. occidentalis, N. paniculata, N. plumbaginifolia, N. raimondii, N. rosulata, N. simulans, N. stocktonii, N. suaveolens, N. umbrática, N. velutina, N. wigandioides, N. acaulis, N. acuminata, N. attenuata, N. benthamiana, N. cavicola, N. clevelandii, N. cordifolia, N. corymbosa, N. fragrans, N. goodspeedii, N.linearis, N. miersii, N. nudicaulis, N. obtusifolia, N. occidentalis subsp.

Nos. 4,660,577 to Sensabaugh, Jr. et al.; 5,387,416 to White et al.; 7,025,066 to Lawson et al.; 7,798,153 to Lawrence, Jr.; and 8,186,360 to Marshall et al., each of which is incorporated herein by reference. Various types of tobacco, cultivation practices, and harvesting practices are described in Tobacco Production, Chemistry and Technology, Davis et al. (Eds.) (1999), which is incorporated herein. Nicotiana species from which suitable tobacco materials may be obtained may be derived using genetic modification or cross-breeding techniques (e.g., tobacco plants may be genetically modified or cross-bred to increase or decrease the production of components, characteristics, or attributes). See, e.g., the types of genetic modifications of plants set forth in U.S. Patent Nos. 5,539,093 to Fitzmaurice et al.; 5,668,295 to Wahab et al.; 5,705,624 to Fitzmaurice et al.; 5,844,119 to Weigl; 6,730,832 to Dominguez et al.; 7,173,170 to Liu et al.; 7,208,659 to Colliver et al.; and 7,230,160 to Benning et al.; and U.S. patent application 2006 / 0236434 to Conkling et al. and document W02008 / 103935 to Nielsen et al.

The Nicotiana species may, in some embodiments, be selected for the content of various compounds present therein. For example, plants may be selected on the basis that those plants produce relatively high amounts of one or more of the compounds desired to be isolated from them. In certain embodiments, plants of the Nicotiana species (e.g., the community tobacco Galpao) are specifically grown for their abundance of compounds on the leaf surface. Tobacco plants may LQPQCn / 77nZ / q / YIAI -35grown in greenhouses, growth chambers, or outdoors in fields, or grown hydroponically. Various parts or portions of the Nicotiana species plant can be included within a mixture as described herein. For example, substantially the entire plant (e.g., the whole plant) can be harvested and used as such. Alternatively, various parts or pieces of the plant can be harvested or separated for later use after harvest. For example, the flower, leaves, stem, roots, seeds, and various combinations thereof can be isolated for further use or processing. In some embodiments, the tobacco material comprises the tobacco leaf (sheet).The substrate material described in the present application may include processed tobacco parts or pieces, cured and aged tobacco in the form of essentially natural sheet and / or stem, a tobacco extract, extracted tobacco pulp (e.g., using water as a solvent), or a mixture of the foregoing (e.g., a mixture combining extracted tobacco pulp with granulated cured and aged natural tobacco sheet). In certain embodiments, the tobacco material comprises solid tobacco material selected from the group comprising sheet and stems. The tobacco used for the substrate material preferably includes tobacco sheet, or a mixture of tobacco sheet and stem (at least a portion of which is smoke-treated). Portions of the tobaccos within the substrate material may be in processed forms, such as processed tobacco stems (e.g., cut-rolled stems, cut-rolled-expanded stems, or cut-blown stems), or bulk-expanded tobacco (e.g., blown tobacco, such as dry ice expanded tobacco (DIET)). See, e.g., the tobacco expansion processes disclosed in U.S. Patents 4,340,073 to Burde et al.; 5,259,403 to Guy et al.; and 5,908,032 to Poindexter, et al. and 7,556,047 to Poindexter, et al, all of which are incorporated by reference.In addition, the substrate material may optionally incorporate fermented tobacco. See also the types of tobacco processing techniques disclosed in document WO2005 / 063060 to Atchley et al., which is incorporated herein by reference. Tobacco material is typically used in a form that can be described as particulate (i.e., crushed, ground, granulated, or powdered). The manner in which the tobacco material is provided in a finely divided or powdered form may vary. Preferably, the plant parts or pieces are crushed, ground, or pulverized into particulate form using crushing, milling, or similar equipment and techniques. Most preferably, the plant material is in a relatively dry form during crushing or milling, using equipment such as hammer mills, cutter heads, air control mills, or the like. For example, the tobacco parts or pieces may be ground or crushed when the moisture content thereof is less than about 15 percent by weight or less than about 5 percent by weight. More preferably, the tobacco material is used LQRQCn / ZZnZ / q / YIAI -36 in the form of pieces or parts having an average particle size between 1.4 millimeters and 250 microns. In some cases, the tobacco particles may be sized to pass through a screening mesh to obtain the required particle size range. If desired, air classification equipment may be used to ensure that small tobacco particles of the desired sizes, or range of sizes, are collected. If desired, granulated tobacco pieces of different sizes may be blended. The manner in which the tobacco is provided in finely divided or powdered form may vary. Preferably, the tobacco parts or pieces are crushed, ground, or pulverized into a powder using milling, grinding, or similar equipment and techniques. Most preferably, the tobacco is in a relatively dry form during crushing or grinding, using equipment such as hammer mills, cutter heads, air control mills, or the like. For example, the tobacco parts or pieces may be ground or crushed when their moisture content is less than about 15 percent by weight to less than about 5 percent by weight. For example, the tobacco plant or portion thereof may be separated into individual parts or pieces (e.g., leaves may be separated from stalks, and / or stalks and leaves may be separated from the stalk).The harvested plant or individual parts or pieces may be subdivided into parts or pieces (e.g., leaves may be shredded, cut, crushed, pulverized, or ground into pieces or parts that may be characterized as filler-type pieces, granules, particles, or fine powders). The plant, or parts thereof, may be subjected to external forces or pressures (e.g., by being pressed or subjected to roller treatment). By carrying out such processing conditions, the plant or part thereof may have a moisture content that approximates its natural moisture content (e.g., its moisture content immediately after harvest), a moisture content achieved by adding moisture to the plant or part thereof, or a moisture content that results from drying the plant or part thereof.For example, pulverized, crushed, or ground plant pieces or portions thereof may have a moisture content of less than 25 percent by weight, often less than 20 percent by weight, and frequently less than 15 percent by weight. For the preparation of oral products, a harvested Nicotiana plant typically undergoes a curing process. Tobacco materials that are incorporated into the substrate material for inclusion in the products described herein are those that have been properly cured and / or aged. Various types of curing processes for various types of tobacco are described in Tobacco Production, Chemistry and Technology, Davis et al. (Eds.) (1999). Examples of air-cured tobacco curing techniques and conditions are set forth in Nestor et al., Beitrage Tabakforsch. Int., 20, 467-475 (2003) and US Patent 6,895,974 to Peele, which are incorporated herein by reference. LQPQCn / 77nZ / q / YIAI - 37Representative techniques and conditions for air-curing tobacco are set forth in U.S. Patent 7,650,892 to Graves et al.; Roton et al., Beitrage Tabakforsch. Int., 21, 305-320 (2005) and Staaf et al., Beitrage Tabakforsch. Int., 21, 321-330 (2005), which are incorporated herein by reference. Some types of tobacco may be subjected to other types of curing processes, such as fire curing or sun curing. In certain embodiments, tobacco materials that may be employed include flue-cured or Virginia tobaccos (e.g., K326), Burley, sun-cured (e.g., Indian Kumool and Oriental tobaccos including Katerini, Prelip, Komotini, Xanthi, and Yambol), Maryland, dark, dark-cooked, dark air-cured (e.g., Madole, Passanda, Cubano, Jatin, and Bezuki tobaccos), ligero air-cured (e.g., North Wisconsin and Galpao tobaccos), Indian air-cured, Red Russian, and Rustica, as well as other rare or specialty tobaccos and various blends of any of the foregoing tobaccos. The tobacco material may also be in a so-called blended form. For example, the tobacco material may include a mixture of parts or pieces of fire-cured tobacco, Burley (e.g., Malawi Burley tobacco), and oriental tobaccos (e.g., as tobacco composed of, or derived from, tobacco leaf, or a mixture of tobacco leaf and tobacco stem). For example, a representative blend may incorporate between 30 and 70 parts of Burley tobacco (e.g., leaf, or leaf and stem), and between 30 and 70 parts of fire-cured tobacco (e.g., stem, leaf, or leaf and stem) by dry weight.Other examples of tobacco blends incorporate about 75 parts flue-cured tobacco, about 15 parts Burley tobacco, and about 10 parts Oriental tobacco; or about 65 parts flue-cured tobacco, about 25 parts Burley tobacco, and about 10 parts Oriental tobacco; or about 65 parts flue-cured tobacco, about 10 parts Burley tobacco, and about 25 parts Oriental tobacco, by dry weight. Other examples of tobacco blends incorporate between 20 and 30 parts Oriental tobacco and between 70 and 80 parts flue-cured tobacco, by dry weight. The tobacco materials used in the present invention may be subjected to, for example, fermentation, bleaching, and the like. If desired, the tobacco materials may be, for example, irradiated, pasteurized, or subjected to a controlled heat treatment. Such treatment processes are detailed, for example, in U.S. Patent 8,061,362 to Mua et al., which is incorporated herein by reference.In certain embodiments, the tobacco materials may be treated with water and an additive capable of inhibiting the reaction of asparagine to form acrylamide upon heating of the tobacco material (e.g., an additive selected from the group consisting of lysine, glycine, histidine, alanine, methionine, cysteine, glutamic acid, aspartic acid, proline, phenylalanine, valine, arginine, compositions incorporating di- and trivalent cations, asparaginase, certain non-reducing saccharides, certain reducing agents, phenolic compounds, certain compounds having at least one free thiol group or functionality, oxidizing agents, oxidation catalysts, natural plant extracts (e.g., rosemary extract), and combinations thereof). See, for example, process types. LQPOcn / zznz / q / YiAi - 38treatment methods described in U.S. Patents 8,434,496, 8,944,072, and 8,991,403 to Chen et al., which are incorporated herein by reference. In certain embodiments, this type of treatment is useful when the original tobacco material is subjected to heat in the processes described above. In some embodiments, the type of tobacco material is selected so that it initially has a visually lighter color than other tobacco materials to some degree (e.g., bleached or decolorized). The tobacco pulp may be bleached in certain embodiments by any means known in the art. For example, bleached tobacco material produced by various bleaching methods using various bleaching or oxidizing agents and oxidation catalysts may be used. Exemplary oxidizing agents include peroxides (e.g., hydrogen peroxide), chlorite salts, chlorate salts, perchlorite salts, hypochlorite salts, ozone, ammonia, potassium permanganate, and combinations thereof. Examples of oxidation catalysts are titanium dioxide, manganese, and combinations thereof. Processes for treating tobacco with bleaching agents are discussed, for example, in U.S. patents 787.611 Daniels, Jr.; 1,086,306 to Oelenheinz; 1,437,095 to Delling; 1,757,477 to Rosenhoch; 2,122,421 to Hawkinson; 2,148,147 to Baier; 2,170,107 to Baier; 2,274,649 to Baier; 2,770,239 to Prats et ah; 3,612,065 to Rosen; 3,851,653 to Rosen; 3,889,689 to Rosen; 3,943,940 to Minami; 3,943,945 to Rosen; 4,143,666 to Rainer; 4,194,514 to Campbell; 4,366,823, 4,366,824 and 4,388,933 to Rainer et al.4,641,667 to Schmekel et ah; 5,713,376 to Berger; 9,339,058 to Byrd Jr. et al; 9,420,825 to Beeson et al. and 9,950,858 to Byrd Jr. et al; as well as in US patent applications 2012 / 0067361 to Bjorkholm et al; 2016 / 0073686 to Crooks; 2017 / 0020183 to Bjorkholm; and 2017 / 0112183 to Bjorkholm, and in WO1996 / 031255 to Giolvas and WO2018 / 083114 to Bjorkholm, all of which are incorporated herein by reference. In some embodiments, the bleached tobacco material may have an ISO brightness of at least 50%, at least 60%, at least 65%, at least 70%, at least 75%, or at least 80%. In some embodiments, the bleached tobacco material may have an ISO brightness in the range of about 50% to about 90%, about 55% to about 75%, or about 60% to about 70%. The ISO brightness may be measured according to ISO 3688:1999 or ISO 2470-1:2016. In some embodiments, bleached tobacco material may be characterized as lighter in color (e.g., bleached) compared to untreated tobacco material. White colors are typically defined by reference to the International Commission on Illumination (CIE) chromaticity diagram. Bleached tobacco material may, in certain embodiments, be characterized as closer to pure white on the chromaticity diagram than untreated tobacco material. In various embodiments, the tobacco material may be treated to extract a soluble component of the tobacco material. In this regard, Tobacco Extract, as LQRQCn / 77nZ / q / YIAI -39as used herein, refers to isolated components of a tobacco material that are extracted from solid tobacco pulp by a solvent contacting the tobacco material in an extraction process. Various tobacco material extraction techniques can be used to provide a tobacco extract and a solid tobacco material. See, e.g., the extraction processes described in U.S. patent application 2011 / 0247640 to Beeson et al., which is incorporated herein by reference. Other examples of tobacco component extraction techniques are described in U.S. patents 4,144,895 to Fiore; 4,150,677 to Osborne, Jr. et al.; 4,267,847 to Reid; 4,289,147 to Wildman et al.; 4,351,346 to Brummer et al.; 4,359,059 to Brummer et al. 4,506,682 to Muller; 4,589,428 to Keritsis; 4,605,016 to Soga et al; 4,716,911 to Poulose et al; 4,727,889 to Niven, Jr. et al; 4,887,618 to Bemasek et al; 4,941,484 to Clapp et al; 4,967.771 to Fagg et al; 4,986,286 to Roberts et al; 5,005,593 to Fagg et al; 5,018,540 to Grubbs et al; 5,060,669 to White et al; 5,065,775 to Fagg; 5,074,319 to White et al; 5,099,862 to White et al; 5,121,757 to White et al; 5,131,414 to Fagg; 5,131,415 to Muñoz et al; 5,148,819 to Fagg; 5,197,494 to Kramer; 5,230,354 to Smith et al; 5,234,008 to Fagg; 5,243,999 to Smith; 5,301,694 to Raymond et al.; 5,318,050 to Gonzalez-Parra et al.; 5,343,879 to Teague; 5,360,022 to Newton; 5,435,325 to Clapp et al.; 5,445,169 to Brinkley et al.; 6,131,584 to Lauterbach; 6,298,859 to Kierulff et al.; 6,772,767 to Mua et al.; and 7,337,782 to Thompson, all of which are incorporated by reference herein. Typical inclusion ranges for tobacco materials may vary depending on the nature and type of the tobacco material, and the intended effect on the final blend, with an exemplary range of up to about 30% by weight (or up to about 20% by weight or up to about 10% by weight or up to about 5% by weight), based on the total weight of the blend (e.g., about 0.1 to about 15% by weight). It should be noted that the inclusion of a tobacco material in the compositions and products described herein is optional and not required. In some embodiments, the oral products described herein may be generally characterized as tobacco-free. For example, in some embodiments, the oral products of the present invention may be said to be completely free or substantially free of tobacco material (other than purified nicotine as the active ingredient). Oral products referred to as completely free of or substantially free of a tobacco material herein refer to oral products that may be characterized as having less than about 1.0% by weight, less than about 0.5% by weight, less than about 0.1% by weight of tobacco material, or 0% by weight of tobacco material. Other additives In some embodiments, one or more additional additives may be included in the substrate material.

In some embodiments, the compositions and products may include at least 1%, at least 2%, at least 5%, at least 10%, or at least 20% by weight of water. In some embodiments, the substrate material may include a content of one or more organic acids. As used herein, the term “organic acid” refers to an organic (i.e., carbon-based) compound characterized by its acidic properties. Typically, organic acids are relatively weak acids (i.e., do not completely dissociate in the presence of water), such as carboxylic acids (-CO2H) or sulfonic acids (-SO2OH). As used herein, reference to an organic acid means an organic acid that is intentionally added. In this regard, an organic acid may be intentionally added as a specific ingredient rather than simply being inherently present as a component of another ingredient (e.g., the small amount of organic acid that may be inherently present in an ingredient such as a tobacco material).In some embodiments, the one or more organic acids are added alone (i.e., in their native free acid, solid, or liquid form) or as a solution in, for example, water. In some embodiments, the one or more organic acids are added in salt form, as described below. In some embodiments, the organic acid is an alkyl carboxylic acid. Non-limiting examples of alkyl carboxylic acids include formic acid, acetic acid, propionic acid, octanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, and the like.

In organic acids containing multiple carboxylic acids (e.g., two to four carboxylic acid groups), one or more of the carboxylic acid groups may be esterified. Non-limiting examples include succinic acid monoethyl ester, monomethyl fumarate, monomethyl or dimethyl citrate, and the like. In some embodiments, the organic acid may include more than one carboxylic acid group and one or more hydroxyl groups. Non-limiting examples of such acids include tartaric acid, citric acid, and the like. In some embodiments, the organic acid is an aryl carboxylic acid or an aryl sulfonic acid. Non-limiting examples of aryl carboxylic and sulfonic acids include benzoic acid, toluic acids, salicylic acid, benzenesulfonic acid, and / or p-toluenesulfonic acid.

The amount of organic acid present in the compositions can vary. Generally, the compositions may comprise from 0 to about 10% by weight of organic acid, present as one or more organic acids, based on the total weight of the substrate material. In some embodiments, the substrate material may further comprise a salt (e.g., alkali metal salts), typically employed in an amount sufficient to provide the desired sensory attributes to the compositions and products. Non-limiting examples of suitable salts include sodium chloride, potassium chloride, ammonium chloride, flour salt, and the like. When present, a representative amount of salt is about 0.5 weight percent or more, about 1.0 weight percent or more, or about 1.5 weight percent or more, but will typically constitute about 10 percent or less of the total weight of the substrate material, or about 7.5 percent or less, or about 5 percent or less (e.g., about 0.5 to about 5 weight percent). The substrate material may also include one or more sweeteners. Sweeteners may be any sweetener or combination of sweeteners, in natural or artificial form, or as a combination of natural and artificial sweeteners. Examples of sweeteners LQPQCn / 77nZ / q / YIAI -42Natural sweeteners include fructose, sucrose, glucose, maltose, mannose, galactose, lactose, isomaltulose, stevia, honey, and the like. Examples of artificial sweeteners include sucralose, maltodextrin, saccharin, aspartame, acesulfame K, neotame, and the like. In some embodiments, the sweetener comprises one or more sugar alcohols.

In some embodiments, the substrate material may include one or more binding agents. In certain embodiments, a binder (or a combination of binders) may be employed in amounts sufficient to provide the desired physical attributes and physical integrity of the composition, and the binders also often function as thickening or gelling agents. Typical binders may be organic or inorganic, or a combination thereof. Representative binders include povidone, sodium alginate, starch-based binders, pectin, carrageenan, pullulan, zein, and the like, as well as combinations thereof. In some embodiments, the binder comprises pectin or carrageenan, or combinations thereof.The amount of binder used may vary, but is typically up to 30 weight percent, and certain embodiments are characterized by a binder content of at least 0.1 weight percent, such as 1 to 30 weight percent, or 5 to 10 weight percent, based on the total weight of the substrate material. In certain embodiments, the binder includes a gum, e.g., a natural gum.

When included, the humectant is typically provided in an amount sufficient to provide desired wetness attributes to the compositions. Additionally, in some instances, the humectant may impart desirable flow characteristics to the composition for depositing it into a mold. When present, a humectant will typically constitute about 5% or less of the weight of the substrate material (e.g., about 0.5 to about 5% by weight). When present, a representative amount of humectant is about 0.1% to about 1% by weight, or about 1% to about 5% by weight, based on the total weight of the substrate material. In certain embodiments, the substrate materials of the present invention may comprise pH adjusters or buffering agents. Examples of pH adjusters and buffering agents that may be used include, but are not limited to, metal hydroxides (e.g., alkali metal hydroxides such as sodium hydroxide and potassium hydroxide), and other alkali metal buffers such as metal carbonates (e.g., potassium carbonate or sodium carbonate), or metal bicarbonates such as sodium bicarbonate, and the like.When present, the buffering agent is typically present in an amount of less than about 5 percent based on the weight of the substrate material, for example, from about 0.5% to about 5%, such as, for example, from about 0.75% to about 4%, from about 0.75% to about 3%, or from about 1% to about 2% by weight, based on the total weight of the substrate material. Non-limiting examples of suitable buffers include alkali metal acetates, glycinates, phosphates, glycerophosphates, citrates, carbonates, hydrogen carbonates, borates, or mixtures thereof.

See, for example, representative components, combination of components, relative amounts of such components, and forms and methods for employing such components, set forth in U.S. Patent Nos. 9,237,769 to Mua et al., 7,861,728 to Holton, Jr. et al., U.S. patent applications 2010 / 0291245 to Gao et al., and 2007 / 0062549 to Holton, Jr. et al., each of which is incorporated herein by reference.Typical ranges of inclusion of such additional additives may vary depending on the nature and function of the additive and the intended effect on the final mixture, with an exemplary range of up to about 10% by weight, based on the total weight of the substrate material (e.g., from about 0.1 to about 5% by weight). The aforementioned additives may be used together (e.g., as additive formulations) or separately (e.g., individual additive components may be added at different stages of preparing the final substrate material). Furthermore, the aforementioned types of additives may be encapsulated as provided in the final product or substrate material. Exemplary encapsulated additives are described, for example, in WO2010 / 132444 to Atchley, which is hereby incorporated by reference. Particles In some embodiments, one or more of a filler component, a tobacco material, and the general substrate material described herein may be described as a particulate material. As used herein, the term "particle" refers to a material in the form of a plurality of individual particles, some of which may be in the form of a multi-particle agglomerate, wherein the particles have an average length-to-width ratio of less than 2:1, such as less than 1.5:1, such as about 1:1. In various embodiments, the particles of a particulate material may be described as substantially spherical or granular. The particle size of a particulate material can be measured by particle size analysis. As the skilled person will readily appreciate, sieve analysis (also known as gradation testing) is a method used to measure the particle size distribution of a particulate material. Typically, sieve analysis involves a nested column of sieves comprising screens, preferably in the form of wire mesh. A pre-weighed sample may be introduced onto the top sieve in the column, which has the largest mesh openings (i.e., the largest sieve pore diameter). Each lower sieve in the column has progressively smaller openings or mesh sizes than the top sieve. Typically, a receiving portion is located at the base of the sieve column. LQPQCn / 77nZ / q / YIAI -45to collect any particles that are smaller than the sieve opening or mesh size of the lowest or bottom sieve in the column (which has the smallest sieve opening or mesh). In some embodiments, the sieve column may be placed on or in a mechanical shaker. The shaker causes each of the sieves in the column to vibrate. The mechanical shaker may be activated for a predetermined period of time to ensure that all particles are collected on the correct sieve. In some embodiments, the sieve column is shaken for a period of time from 0.5 minutes to 10 minutes, such as from 1 minute to 10 minutes, such as from 1 minute to 5 minutes, such as for approximately 3 minutes. After the shaking of the sieves in the column is complete, the material collected on each sieve is weighed. The weight of each sample on each sieve may be divided by the total weight to obtain a percentage of the mass retained on each sieve.As will be readily appreciated by those skilled in the art, the sieve opening sizes or mesh sizes of each sieve in the column used for sieving analysis may be selected based on the granularity or known maximum / minimum particle sizes of the sample to be analyzed. In some embodiments, a sieve column may be used for sieve size analysis, wherein the column comprises 2 to 20 sieves, for example 5 to 15 sieves. In some embodiments, a sieve column may be used for sieve analysis, wherein the column comprises 10 sieves. In some embodiments, the largest screen opening or mesh sizes of the sieves used for sieving analysis may be 1000 µm, such as 500 µm, such as 400 µm, such as 300 µm.

Preparation of the substrate material The way in which the various components of the substrate material are combined can vary. As such, the overall mixture of the various components with, for example, the components of the powder mix may be relatively uniform in nature. LQPQCn / 77nZ / q / YIAI- 47The components noted above, which may be in liquid or dry solid form, may be mixed in a pretreatment step prior to mixing with any other components of the substrate material, or simply mixed together with all other liquid or dry ingredients. The various components of the substrate material may be contacted, combined, or mixed using any mixing technique or equipment known in the art. Any mixing method that brings the substrate ingredients into intimate contact may be used, such as a mixing apparatus with an impeller or other structure capable of agitation. Examples of mixing equipment include shell drums, conditioning cylinders or drums, liquid spray apparatus, cone-type mixers, ribbon mixers, mixers available as the FKM130, FKM600, FKM1200, FKM2000, and FKM3000 from Littleford Day, Inc., Hobart mixers, and the like.See also, for example, the types of methodologies set forth in U.S. Patents 4,148,325 to Solomon et al.; 6,510,855 to Korte et al.; and 6,834,654 to Williams, each of which is incorporated herein by reference. In some embodiments, the components forming the substrate material are prepared such that a mixture thereof can be used in a starch molding process to form the mixture. Manner and methods of formulating the mixtures will be apparent to those skilled in the art. See, for example, the types of methodologies set forth in U.S. Patents 4,148,325 to Solomon et al.; 6,510,855 to Korte et al.; and 6,834,654 to Williams, 4,725,440 to Ridgway et al., and 6,077,524 to Bolder et al., each of which is incorporated herein by reference. Method of manufacturing bagged products An exemplary bag may be constructed of materials, and in such a manner, that during use by the user, the bag undergoes controlled dispersion or dissolution of the releasable component embedded in the bag and, subsequently, one or more components of the substrate material. Such bag materials may be in the form of mesh, screen, perforated paper, permeable fabric, or the like. Preferably, water-permeable bag materials are provided by forming a bag with the fleece materials described above. Such fleece materials advantageously retain the releasable components therein while having sufficient permeability to allow passage of the components in the substrate material through the fleece material into the bag and to the user of the product.As a result, the releasable component and substrate material can undergo complete dispersion within the user's mouth during normal use, and thus the releasable component and substrate material can be ingested by the user. In some embodiments, the fleece material itself can be dissolvable or disintegrable, such that the pouch and substrate material can be ingested by the user. Preferred pouch materials, while being water-dispersible or dissolvable, can be designed and manufactured such that, in. LQPQCn / 77nZ / q / YIAI - Under normal use conditions, a significant amount of the contents of the substrate material will leak through the bag material before the bag suffers a loss of its physical integrity. Examples of packets, pouches, or containers of the type used for the manufacture of smokeless tobacco products are available under the trade names CatchDry, Ettan, General, Granit, Goteborgs Rape, Grovsnus White, Metropol Kaktus, Mocea Anise, Mocea Mint, Mocea Wintergreen, Kicks, Probe, Prince, Skruf, and TreAnkrare. The mixture may be contained in pouches and packaged, in a manner and using the types of components used for the manufacture of conventional types of snus. The pouch provides a liquid-permeable container of a type that may be considered similar in character to the type of mesh material used for the construction of a tea bag. The components of the mixture diffuse readily through the pouch and into the mouth of the user. Non-limiting examples of suitable types of pouches and methods of forming such pouches are set forth, for example, in U.S. Patents 5,167,244 to Kjerstad and 8,931,493 to Sebastian et al.; as well as U.S. patent applications 2016 / 0000140 to Sebastian et al.; 2016 / 0073689 to Sebastian et al.; 2016 / 0157515 to Chapman et al.; and 2016 / 0192703 to Sebastian et al., each of which is incorporated herein by reference. The bags may be provided as individual bags, or a plurality of bags (e.g., 2, 4, 5, 10, 12, 15, 20, 25, or 30 bags) may be connected or linked together (e.g., end-to-end) such that a single bag or individual portion may be readily removed for use from a single-piece string or array of bags. The amount of material contained in each product unit, for example, a pouch, may vary. In some embodiments, the weight of the substrate material within each pouch is at least about 50 mg, for example, from about 50 mg to about 2 grams, from about 100 mg to about 1.5 grams, or from about 200 to about 700 mg. In some smaller embodiments, the weight of the substrate material within each pouch may be from about 100 to about 300 mg. In a larger embodiment, the weight of the substrate material within each pouch may be from about 300 mg to about 700 mg. If desired, each pouch may contain other components. For example, within each pouch there may be at least one strip, piece, or sheet of water-dispersible or water-soluble flavored material (e.g., an edible film-type breath freshener material), along with or without at least one capsule. These strips or sheets can be folded or wrinkled to be easily incorporated into the bag.See, for example, the types of materials and technologies disclosed in US Patent Nos. 6,887,307 to Scott et al. and 6,923,981 to Leung et al.; and The EFSA Journal (2004) 85, 1-32; which are incorporated herein by reference. Configured for oral use This document offers products configured for oral use. Regardless of whether the product is provided in the form of an unpackaged product, LQPQCn / 77nZ / q / YIAI -49configured for oral use, as shown in Figure 2, or in the form of a pouch product configured for oral use, as shown in Figure 1; the term configured for oral use, as used herein, means that the product is provided in a form such that, during use, saliva in the mouth of the user causes one or more of the releasable components (e.g., a flavoring agent and / or an active ingredient) and the substrate material in which it is included (e.g., prepared in accordance with the methods and compositions provided herein) to pass into the mouth of the user.In certain embodiments, the product is adapted to deliver releasable components to a user through the mucous membranes of the user's mouth, and in some cases, said releasable component is an active ingredient (including, but not limited to, for example, nicotine) that can be absorbed through the mucous membranes of the mouth when using the product. Products configured for oral use, as described herein, may take a variety of forms, including, but not limited to, unpackaged products (which may be in the form of, for example, an orally administered fleece material or an oral film), and pouched products. Some of these products may have, for example, one or more of the following characteristics: crunchy, grainy, chewy, syrupy, pasty, spongy, soft, and / or creamy. In certain embodiments, the desired textural property may be selected from the group consisting of stickiness, cohesiveness, density, dryness, fracturability, graininess, gumminess, hardness, heaviness, moisture absorption, moisture release, mouth coating, roughness, slipperiness, smoothness, viscosity, wetness, and combinations thereof. Products comprising the fleece materials of the present invention may be at least partially dissolvable. As used herein, the terms “dissolve” and “dissolvable” refer to fleece materials and substrate materials having water-soluble components that interact with moisture in the oral cavity and go into solution, thereby causing gradual consumption of the product. In one aspect, the dissolvable product is capable of remaining in the user’s mouth for a given period of time until it completely dissolves. Dissolution rates may vary over a wide range, from about 1 minute or less to about 60 minutes. For example, rapid-release mixtures typically dissolve and / or release the active ingredient in about 2 minutes or less, often in 1 minute or less (e.g., about 50 seconds or less, about 40 seconds or less, about 30 seconds or less, or about 20 seconds or less).Dissolution can occur by any means, such as melting, mechanical disruption (e.g., mastication), enzymatic or other chemical degradation, or by disrupting the interaction between the components of the mixture. In other embodiments, the products do not dissolve while the product is in the user's mouth. LQRQCn / ZZnZ / q / YIAI -50In some embodiments, oral products comprising a fleece material with a releasable component, and optionally containing a substrate material, may be provided in the form of a pouch product (e.g., a water-permeable pouch formed from the fleece material) or in an unpackaged configuration as described above. These oral products are typically used by placing a unit (i.e., a pouch or unpackaged product) containing the releasable component, and optionally a substrate material, in the mouth of a human subject / user. Typically, the unit is placed somewhere within the user's oral cavity, e.g., beneath the lips, in the same manner that moist tobacco products are generally used. Preferably, the unit is not chewed or swallowed.Exposure to saliva causes some of the releasable components therein (e.g., flavoring agents and / or active ingredients, such as nicotine) to be released into the mouth of the user, and further may cause some of the substrate material therein to pass through, e.g., the fleece material and provide the user with flavor and satisfaction, and the user is not required to spit out any portion of the mixture. After about 10 minutes to about 60 minutes, typically about 15 minutes to about 45 minutes, of use / enjoyment, substantial amounts of the releasable component and / or the substrate material have been ingested by the human subject, and the unit may be removed from the mouth of the human subject for disposal. The above embodiments are provided by way of example only, and the oral products of the present invention may include various releasable components and various substrate materials in other forms. An unpackaged product and / or a pouched product as described herein may be packaged within any suitable inner packaging material and / or outer container. See also, for example, the various types of packages for smokeless types of products set forth in U.S. Patent Nos. 7,014,039 to Henson et al.; 7,537,110 to Kutsch et al.; 7,584,843 to Kutsch et al.; 8,397,945 to Gelardi et al., D592,956 to Thiellier; D594,154 to Patel et al.; and D625,178 to Bailey et al.; in U.S. patent applications 2008 / 0173317 to Robinson et al.; 2009 / 0014343 to Clark et al.; 2009 / 0014450 to Bjorkholm; 2009 / 0250360 to Bellamah et al; 2009 / 0266837 to Gelardi et aL; 2009 / 0223989 to Gelardi; 2009 / 0230003 to Thiellier; 2010 / 0084424 to Gelardi; and 2010 / 0133140 to Bailey et aL; 2010 / 0264157 to Bailey et aL; and 2011 / 0168712 to Bailey et aL which are incorporated herein by reference. Many modifications and other embodiments of the invention will occur to one skilled in the art to which this invention pertains, having benefited from the teachings presented in the foregoing description. Therefore, it should be understood that the invention should not be limited to the specific embodiments described and that aspects and other embodiments should be included within the scope of the appended claims.
