Abstract

An oral tobacco product includes a body that is wholly receivable in an oral cavity. The body includes a mouth-stable polymer matrix and tobacco fibers embedded in the mouth-stable polymer matrix. The oral tobacco product can be formed by extruding a mixture of mouth-stable polymer and tobacco fibers.

First claim

What is claimed is:

1. An oral tobacco product, comprising a body that is wholly receivable in an oral cavity, the body comprising:
a mouth-stable polymer matrix comprising at least 60% weight percent of one or more mouth-stable polymers, the one or more mouth-stable polymers comprising a polyurethane;
at least 10 weight percent of tobacco fibers embedded in the mouth-stable polymer matrix that together form a fiber-polymer matrix, the tobacco fibers having an average fiber size of less than 200 micrometers; and
an additive comprising nicotine or a derivative thereof that is absorbed into the fiber-polymer matrix,
wherein the body has a plurality of pores having a pore diameter of between 40 microns and 60 microns and a plurality of pores having a pore diameter of between 1 micron and 10 microns,
wherein the body is formed by extruding a mixture comprising the one or more mouth-stable polymers and the tobacco fibers, and
wherein the body has a compressibility @250 N of between 45% and 95%.

2. An oral tobacco product, comprising a body that is wholly receivable in an oral cavity, the body comprising:
a mouth-stable polymer matrix comprising at least 60% weight percent of one or more mouth-stable polymers, the one or more mouth-stable polymers comprising a polyurethane;
at least 10 weight percent of tobacco fibers embedded in the mouth-stable polymer matrix that together form a fiber-polymer matrix, the tobacco fibers having an average fiber size of less than 200 micrometers; and
an additive comprising nicotine or a derivative thereof that is absorbed into the fiber-polymer matrix,
wherein the body has a plurality of pores having a pore diameter of between 40 microns and 60 microns and a plurality of pores having a pore diameter of between 1 micron and 10 microns,
wherein the body is formed by extruding a mixture comprising the one or more mouth-stable polymers and the tobacco fibers, and
wherein the body has a compressibility @425 N of between 60% and 99%.

3. An oral tobacco product, comprising a body that is wholly receivable in an oral cavity, the body comprising:
a mouth-stable polymer matrix comprising at least 60% weight percent of one or more mouth-stable polymers, the one or more mouth-stable polymers comprising a polyurethane;
at least 10 weight percent of tobacco fibers embedded in the mouth-stable polymer matrix that together form a fiber-polymer matrix, the tobacco fibers having an average fiber size of less than 200 micrometers; and
an additive comprising nicotine or a derivative thereof that is absorbed into the fiber-polymer matrix,
wherein the body has a plurality of pores having a pore diameter of between 40 microns and 60 microns and a plurality of pores having a pore diameter of between 1 micron and 10 microns,
wherein the body is formed by extruding a mixture comprising the one or more mouth-stable polymers and the tobacco fibers, and
wherein the body has a percentage of springiness of at least 20%.

4. The oral tobacco product of claim 1 , wherein the mouth-stable polymer matrix comprises a polyester.

5. The oral tobacco product of claim 1 , wherein the mouth-stable polymer matrix comprises a polyacrylate.

6. The oral tobacco product claim 1 , wherein the mouth-stable polymer matrix comprises a polyethylene, SEBS, SBS, or a combination thereof.

7. The oral tobacco product of claim 1 , further comprising a plasticizer dispersed in the mouth-stable polymer matrix.

8. The oral tobacco product of claim 7 , wherein the plasticizer is selected from the group consisting of propylene glycol, glycerin, vegetable oil, triglycerides, and combinations thereof.

9. The oral tobacco product of claim 1 , further comprising a sweetener dispersed in the body.

10. The oral tobacco product of claim 9 , wherein the sweetener is selected from the group consisting of saccharine, sucralose, aspartame, acesulfame potassium, and combinations thereof.

11. The oral tobacco product of claim 1 , further comprising a supplemental additive selected from the group consisting of minerals, vitamins, dietary supplements, nutraceuticals, energizing agents, soothing agents, amino acids, chemsthetic agents, antioxidants, botanicals, teeth whitening agents, therapeutic agents, and combinations thereof, wherein the supplemental additive is dispersed in the body or tobacco fibers such that the supplemental additive is released when the body is held within a mouth of an adult tobacco consumer.

12. The oral tobacco product of claim 1 , further comprising a flavorant dispersed in the body or tobacco fibers such that the flavorant is released when the body is held within a mouth of an adult tobacco consumer.

13. The oral tobacco product of claim 12 , wherein the flavorant is selected from the group consisting of licorice, wintergreen, cherry and berry type flavorants, Dramboui, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cinnamon, cardamon, apium graveolents, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, Japanese mint, cassia, caraway, cognac, jasmine, chamomile, menthol, ylang, sage, fennel, pimenta, ginger, anise, coriander, coffee, mint oils from a species of the genus Mentha, and combinations thereof.

14. The oral tobacco product of claim 1 , wherein the body is shield shaped.

15. The oral tobacco product of claim 1 , wherein the body has a diameter of between 5 mm and 25 mm and a thickness of between 1 mm and 10 mm.

16. The oral tobacco product of claim 1 , further comprising non-tobacco cellulosic fibers.

17. The oral tobacco product of claim 16 , wherein the non-tobacco cellulosic fibers are sugar beet fibers, wood pulp fiber, cotton fiber, bran fiber, citrus pulp fiber, grass fiber, willow fiber, and poplar fiber.

18. The oral tobacco product of claim 1 , wherein the body has a compressibility @250 N of less than 80%.

19. The oral tobacco product of claim 1 , wherein the body has a compressibility @250 N of between 45% and 90%.
