Polymer encased smokeless tobacco products
Methods for encasing bodies including smokeless tobacco or a tobacco substitute with a polymeric casing can include coating a compressed body with microfibers, applying tubular casings to compressed bodies, printing netting and webs on compressed bodies, injection molding around compressed bodies, applying a webbing to compressed bodies, placing compressed bodies into a skin forming bath, and including thermoplastic polymers in a compressed body.
1. A method of making a polymer encased smokeless tobacco or tobacco substitute product comprising:
forming a compressed body including smokeless tobacco, a tobacco substitute, or both smokeless tobacco and a tobacco substitute;
depositing rows of polymeric material on each side of the compressed body at at least two different angles to form a netting around the compressed body; and
curing the netting to form the polymer encased smokeless tobacco or tobacco substitute product.
2. The method of claim 1 , wherein the curing includes UV curing.
3. The method of claim 1 , wherein the curing includes heat curing.
4. The method of claim 1 , wherein the depositing includes 3 D printing.
5. The method of claim 1 , wherein the depositing includes hot melt spraying.
6. The method of claim 1 , wherein the depositing includes,
preparing a partially covered body by depositing a first row of polymeric material on the compressed body,
rotating the compressed body, and
depositing a second row of the polymeric material on the partially covered body.
7. The method of claim 6 , wherein the rotating includes rotating the compressed body 90°.
8. The method of claim 1 , further comprising:
depositing the compressed body onto a conveyor,
wherein the forming, the depositing rows of polymeric material, and the curing are performed on the conveyor.
9. The method of claim 1 , wherein
the depositing includes,
depositing a first row of polymeric material on a first side of the compressed body to form a first netting portion, and
depositing a second row of the polymeric material on a second side of the compressed body to form a second netting portion, and the curing includes,
after the depositing the first row of polymeric material and before depositing the second row of the polymeric material, curing the first netting portion, and
after the depositing the second row of the polymeric material, curing the second netting portion.
10. The method of claim 9 , wherein
the first side includes five first sides, and
the second side includes one second side.
11. The method of claim 1 , wherein the polymeric material includes polyurethane.
12. The method of claim 1 , wherein the forming includes forming the compressed body from a flavorant and the smokeless tobacco, the tobacco substitute, or both the smokeless tobacco and the tobacco substitute.
13. A method of making a polymer encased smokeless tobacco or tobacco substitute product comprising:
forming a compressed body including smokeless tobacco, a tobacco substitute, or both smokeless tobacco and a tobacco substitute;
moving the compressed body through a bath including a polymer foam to produce a polymer foam skin on the compressed body; and
curing the polymer foam skin to form the polymer encased smokeless tobacco or tobacco substitute product.
14. The method of claim 13 , wherein the moving includes conveying the compressed body on a conveyor.
15. The method of claim 13 , wherein the polymer foam skin includes polyurethane foam, PVC foam, Styrofoam, or any combination thereof.
