Abstract

A smokeless tobacco product includes smokeless tobacco and a polymeric material in intimate contact with the smokeless tobacco and stabilized in conformance to a surface topography of the tobacco'"'"'s fibrous structures such that the stabilized polymeric material secures the smokeless tobacco together. The smokeless tobacco product has a moisture-permeable porous surface and an overall oven volatiles content of at least 10 weight percent.

Claims

1. A smokeless tobacco product comprising:

smokeless tobacco; and

structural fibers comprising a polyurethane material and having a diameter of less than 100 microns, the structural fibers forming a moisture-permeable porous surface around the smokeless tobacco.

2. The smokeless tobacco product of claim 1, wherein the structural fibers are conformed with at least a portion of an outer surface of a body of the smokeless tobacco.

3. The smokeless tobacco product of claim 1, wherein the smokeless tobacco product has an overall oven volatiles content of about 40% by weight to about 60% by weight.

4. The smokeless tobacco product of claim 1, wherein the smokeless tobacco product has dimensional stability.

5. The smokeless tobacco product of claim 1, wherein the polyurethane material is in the form of structural fibers that are at least partially mouth-stable and the smokeless tobacco product is adapted to remain substantially cohesive when placed in an adult tobacco consumer'"'"'s mouth and exposed to saliva.

6. The smokeless tobacco product of claim 1, wherein the structural fibers further comprise polypropylene fibers.

7. The smokeless tobacco product of claim 1, wherein the structural fibers further comprise reconstituted cellulosic fibers.

8. The smokeless tobacco product of claim 7, wherein the reconstituted cellulosic fibers are reconstituted by dissolving and spinning tobacco plant material.

9. The smokeless tobacco product of claim 1, wherein the structural fibers encapsulate a body of the smokeless tobacco.

10. The smokeless tobacco product of claim 1, wherein the polyurethane material is in the form of polyurethane fibers intermingled with cellulosic fibers.

11. The smokeless tobacco product of claim 1, wherein the smokeless tobacco product comprises multiple layers of structural fibers and multiple layers of smokeless tobacco.

12. The smokeless tobacco product of claim 1, wherein the smokeless tobacco product is folded or rolled upon itself.

13. The smokeless tobacco product of claim 1, further comprising a dissolvable film at least partially coating the smokeless tobacco product.

14. The smokeless tobacco product of claim 1, wherein the smokeless tobacco comprises cured tobacco.

15. The smokeless tobacco product of claim 14, wherein the smokeless tobacco comprises cured, aged, fermented tobacco.

16. The smokeless tobacco product of claim 14, wherein the smokeless tobacco comprises cured, aged, non-fermented tobacco.

17. A packaged smokeless tobacco product comprising:

a container that defines a moisture-tight interior space; and

at least one smokeless tobacco product disposed in the moisture-tight interior space, the at least one smokeless tobacco product including smokeless tobacco and structural fibers comprising a polyurethane material and having a diameter of less than 100 microns, the structural fibers forming a moisture-permeable porous surface around the smokeless tobacco.

18. The packaged smokeless tobacco product of claim 17, wherein the at least one smokeless tobacco product comprises a plurality of similarly shaped smokeless tobacco products disposed in the interior space.

19. The packaged smokeless tobacco product of claim 17, wherein the container defines a second interior space for the disposal of used smokeless tobacco products.

20. The packaged smokeless tobacco product of claim 19, wherein the second interior space is moisture permeable.
