Abstract

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.

First claim

What is claimed is:

1. An oral product comprising:
a composition including nicotine; and
a pouch surrounding the composition, the pouch being porous and including, elastomeric fibers, the elastomeric fibers including,
polyurethane.

2. The oral product of claim 1 , wherein the elastomeric fibers include non-woven elastomeric fibers.

3. The oral product of claim 1 , wherein the elastomeric fibers include melt-blown fibers.

4. The oral product of claim 1 , wherein the composition includes a tobacco extract including the nicotine.

5. The oral product of claim 1 , wherein the composition further includes a non-tobacco material.

6. The oral product of claim 5 , wherein the non-tobacco material includes a plant material.

7. The oral product of claim 6 , wherein the plant material has an oven volatiles content of greater than or equal to 10 weight percent.

8. The oral product of claim 7 , wherein the oven volatiles content ranges from 15 weight percent to 25 weight percent.

9. The oral product of claim 7 , wherein the oven volatiles content ranges from 20 weight percent to 30 weight percent.

10. The oral product of claim 7 , wherein the oven volatiles content ranges from 30 weight percent to 50 weight percent.

11. The oral product of claim 7 , wherein the oven volatiles content ranges from 45 weight percent to 65 weight percent.

12. The oral product of claim 6 , wherein the plant material includes thyme, lavender, rosemary, coriander, dill, mint, peppermint, dahlia, cinchona, foxglove, meadowsweet, Echinacea, elderberry, willow bark, tea leaves, red clover, coconut flakes, mint leaves, ginseng, apple, corn silk, grape leaf, basil leaf, or any combination thereof.

13. The oral product of claim 1 , wherein the pouch includes a fabric including the elastomeric fibers.

14. The oral product of claim 13 , wherein the fabric has a basis weight ranging from 1 gram per square meter (gsm) to 350 gsm.

15. The oral product of claim 14 , wherein the basis weight is 30 gsm.

16. The oral product of claim 14 , wherein the basis weight is 21 gsm.

17. The oral product of claim 14 , wherein the basis weight is 15 gsm.

18. The oral product of claim 1 , wherein the elastomeric fibers have diameters of less than or equal to 30 microns.

19. The oral product of claim 18 , wherein the diameters range from 0.5 microns to 30 microns.

20. The oral product of claim 19 , wherein the diameters range from 0.5 microns to 5 microns.

21. The oral product of claim 1 , wherein the elastomeric fibers have diameters ranging from 1 micron to 50 microns.

22. The oral product of claim 1 , further comprising:
a flavorant in the composition, the pouch, or both the composition and the pouch.

23. The oral product of claim 22 , wherein the flavorant includes Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cinnamon, cardamon, apium graveolens, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, Japanese mint, cassia, caraway, cognac, jasmine, chamomile, menthol, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, licorice, a mint oil from a species of the genus Mentha, or any combination thereof.
