Benefits of technology

[0010]The tobacco formulation can be contained within a container, such as a pouch or bag, such as is the type commonly used for the manufacture of snus types of products (e.g., a sealed, moisture permeable pouch that is sometimes referred to as a “portion”). A representative moisture permeable pouch can be composed of a “fleece” type of material. The tobacco formulation is in turn contained within a package. The package is sealed tightly, and is composed of a suitable material, such that the atmospheric conditions within that sealed package are modified and / or controlled; that is, the sealed package can provide a good barrier that inhibits the passage of compositions such as moisture and oxygen therethrough; in addition, the atmosphere within the sealed package can be further modified by introducing a selected gaseous species (e.g., nitrogen, carbon dioxide, argon, or a mixture thereof) into the package prior to sealing or by drawing a vacuum therein (vacuum sealing). As such, the atmospheric conditions to which the tobacco composition is exposed are controlled during conditions of preparation, packing, storage and handling.

Problems solved by technology

The need to keep such formulations refrigerated increases the cost of shipping and storing snus.

example 1

[0071]A tobacco formulation in the form of a somewhat flat strip or film is provided in the following manner.

[0072]Tobacco material, comprised of a mixture of cured and aged flue-cured, burley and Oriental lamina is provided in a strip or leaf form, and at a moisture of about 9 percent. A portion of this tobacco mixture is washed with water, and the solubles or extractable portion that is collected is discarded, and the remaining water insoluble solids (e.g., pulp portion) is dried. The resulting dried pulp portion then is mixed with the retained untreated portion of the original tobacco mixture. That tobacco mixture then is milled to a particle size that passes through a 150 Tyler mesh screen.

[0073]The resulting tobacco mixture is further mixed with other ingredients to form the a formulation that contains about 40 parts of milled tobacco lamina, about 25 parts calcium carbonate, about 15 parts binder (which may be composed of pectin, gelatin, sodium alginate and starch), about 15 ...

example 2

[0078]The smokeless tobacco products that are preferably non-chewable tobacco products that are intended to be placed between the cheek and the gum of the mouth are provided as follows. Preferred smokeless tobacco products, when used orally, completely dissolve in the mouth leaving little to no solid or granular residue, while dispensing or dispersing tobacco components, and while providing a pleasant trigeminal and organoleptic experience.

[0079]Cured and / or aged tobacco lamina or stems is provided in a strip or shredded form, and at a moisture content of about 9 percent, or less. Tobacco types can include flue-cure, burley and Oriental tobaccos, and various combinations thereof. In addition, specialty or exotic types of tobaccos, including tobaccos such as Perique and Cavendish, also can be incorporated within blends of tobacco materials. The lamina or stem is milled under cryogenic conditions, or any other suitable dry milling means, to a fine ground form. The powder is sufficient...

example 3

[0084]A dry mix of about 200 g to about 225 g of granulated tobacco powder of the type described previously in Example 2, a flavoring agent (e.g., mint flavor) and optionally sodium chloride are mixed for about 5 minutes in a table-top Model P400 Popiel™ Automatic Pasta Maker (available from Ronco Inventions, LLC, Chestworth, Calif.). Then, about 48 g portion of a premixed warm aqueous solution (e.g., about 40 g water and about 8 g glycerin) is added to the dry mix. Those contents are mixed for about 3 minutes, or until small pea-like size lumps develop. The pea-like mixture is subsequently extruded via selected dies to obtain flat pasta-like sheets (1.4 cm wide×30 cm length×0.1 to 0.7 cm depth) or noodle-like cylindrical rods (0.1 to 0.7 cm diameter×12 to 24 cm length). The pasta-like sheet is further cut into smaller square or rectangular pieces to obtain pellets that each weigh about 185 mg to about 250 mg. Generally wafer shaped pieces, each weighing about 185 mg to about 250 mg...

Abstract

A smokeless tobacco product is provided. A water-permeable pouch containing a tobacco formulation and configured for insertion into the mouth of a user of that product is provided. The tobacco formulation includes granular tobacco and a buffer comprised of sodium carbonate and sodium bicarbonate. An outer packaging material enveloping the pouch is provided and is sealed so as to allow a controlled environment to be maintained within.

Description

RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. application Ser. No. 11 / 461,628 titled “Smokeless Tobacco” and filed Aug. 1, 2006, and Ser. No. 11 / 461,633 titled “Smokeless Tobacco” and filed Aug. 1, 2006, the entire disclosures of which are incorporated by reference herein.FIELD OF THE INVENTION[0002]The present invention relates to tobacco, and in particular, to tobacco formulations suitable for use in a smokeless manner, and to the handling and use of tobacco that is in a smokeless form.BACKGROUND OF THE INVENTION[0003]Cigarettes, cigars, little cigars and pipes are popular smoking articles that employ tobacco in various forms. Smoking articles are tobacco products that are used by heating or burning tobacco, and aerosol (e.g., smoke) is inhaled by the smoker. Representative manners or methods that have been proposed for the packaging of tobacco products, including cigarettes and cigars, are set forth in U.S. Pat. No. Des 368,221 to Montague; U.S. Pat...
