Smokeless article
A smokeless article for oral consumption including a pouch, the pouch including a porous substrate enclosing a content, the content having a nicotinic compound, wherein the porous substrate has a continuous coatl8ing of a non-porous, saliva-stable material, and wherein the coating is frangible, such that in use the coating fractures on chewing. Also described is a method of manufacturing a smokeless articles for oral consumption the method including applying a coating material to a sheet of a porous substrate to provide a coated sheet of porous substrate, the coated sheet of porous substrate having a continuous coating of a non-porous, saliva-stable material; a forming step; and a sealing step, wherein the coating formed by the coating material is frangible.
1 . A smokeless article for oral consumption comprising a pouch, the pouch comprising a porous substrate enclosing a content which is tobacco-free, the content comprising a nicotinic compound, wherein the porous substrate has a coating of a non-porous, saliva-stable material, wherein the coating is located on at least one of the entire inner surface or entire outer surface of the porous substrate; and wherein the coating is frangible, such that in use the coating fractures on chewing; and wherein the saliva-stable material is a material that does not substantially dissolve or disintegrate as a result of exposure to saliva in an oral cavity of a user at physiological temperature.
2 . The smokeless article of claim 1 , wherein the coating is located on the entire inner surface of the porous substrate.
3 . The smokeless article of claim 1 , wherein the coating is located on the entire outer surface of the porous substrate.
4 . The smokeless article of claim 1 , wherein the non-porous, saliva-stable material comprises a polymer.
5 . The smokeless article of claim 4 , wherein the polymer is selected from sorbitol, maltitol, isomalt, mannitol, starch, gelatin, gum arabic, polyvinyl acetate, carob bean gum, refined paraffin wax, shellac, locust bean gum, petroleum wax, terpene resin, tragacanth, polyethylene, xanthan gum, and combinations thereof.
6 . The smokeless article of claim 1 , wherein essentially an entire enclosed volume of the pouch is defined by the porous substrate.
7 . The smokeless article of claim 1 , wherein the non-porous, saliva-stable material is hydrophobic.
8 . The smokeless article of claim 1 , wherein the coating is applied by spray coating.
9 . A method of manufacturing a smokeless article for oral consumption comprising:
(i) applying a coating material to a sheet of a porous substrate to provide a coated sheet of porous substrate, the coated sheet of porous substrate having a coating of a non-porous, saliva-stable material;
(ii) forming the coated sheet of porous substrate around a content to provide a pouch such that the coated material is located on at least one of the entire inner surface or entire outer surface of the porous substrate, wherein the content is tobacco-free; and
(iii) thermally or chemically sealing the pouch to enclose the contents;
wherein the coating formed by the coating material is frangible, such that in use the coating fractures on chewing; wherein the coating is located on the at least one entire inner surface or entire outer surface of the porous substrate; and wherein the saliva-stable material is a material that does not substantially dissolve or disintegrate as a result of exposure to saliva in an oral cavity of a user at physiological temperature.
10 . The method of claim 9 , wherein in step (ii) the coated sheet of porous substrate is arranged such that the coating of the non-porous, saliva-stable material is provided on an inner surface of the porous substrate.
11 . The method of claim 9 , wherein the coating material is applied by spray-coating.
12 . A smokeless article for oral consumption produced by a process according to claim 9 .
13 . A kit comprising a plurality of smokeless articles according to claim 1 and a container.
14 . Use of the smokeless article according to claim 1 as a smoking substitute device.
