Smokeless tobacco pouch

Abstract

A pouched product adapted for release of a releasable component therefrom is provided herein. The pouched product can include a water-permeable fabric pouch formed so as to define a cavity therein, a composition contained within the cavity of the water-permeable fabric pouch, the composition comprising one or more releasable components that are released from the composition under mouth conditions and that are capable of movement through the water-permeable fabric pouch, and a release modifying agent adapted to react with at least one of the one or more releasable components in the composition and thereby modify the release thereof from the water-permeable fabric pouch.

1 . A pouched product comprising:
 a water-permeable fabric pouch formed so as to define a cavity therein;   a composition contained within the cavity of the water-permeable fabric pouch, the composition comprising one or more releasable components that are released from the composition under mouth conditions and that are capable of movement through the water-permeable fabric pouch; and   a release modifying agent adapted to react with at least one of the one or more releasable components in the composition and thereby modify the release thereof from the water-permeable fabric pouch.   
     
     
         2 . The pouched product of  claim 1 , wherein the fabric pouch is formed of a nonwoven web of fibers. 
     
     
         3 . The pouched product of  claim 1 , wherein the fabric comprises natural fibers. 
     
     
         4 . The pouched product of  claim 1 , wherein the fabric comprises synthetic fibers. 
     
     
         5 . The pouched product of  claim 1 , wherein the fabric comprises cellulosic fibers. 
     
     
         6 . The pouched product of  claim 1 , wherein the fabric comprises a heat sealable binder fiber. 
     
     
         7 . The pouched product of  claim 1 , wherein the release modifying agent forms a part of the fabric. 
     
     
         8 . The pouched product of  claim 1 , wherein the water-permeable fabric pouch is infused with the release modifying agent. 
     
     
         9 . The pouched product of  claim 1 , wherein the release modifying agent is adsorbed or absorbed by at least a portion of the water-permeable fabric pouch. 
     
     
         10 . The pouched product of  claim 1 , wherein the water-permeable fabric pouch comprises a filter media. 
     
     
         11 . The pouched product of  claim 1 , wherein the release modifying agent is admixed with the composition contained within the cavity of the water-permeable fabric pouch. 
     
     
         12 . The pouched product of  claim 1 , wherein the release modifying agent is adapted to bind with at least one of the one or more releasable components in the composition so as to prevent the release of at least a portion of the bound component from the water-permeable fabric pouch. 
     
     
         13 . The pouched product of  claim 1 , wherein the release modifying agent is in an encapsulated form. 
     
     
         14 . The pouched product of  claim 1 , wherein the release modifying agent is adapted to chemically or physically modify at least one of the one or more releasable components in the composition prior to or during release thereof from the water-permeable fabric pouch. 
     
     
         15 . The pouched product of  claim 1 , wherein the release modifying agent is adapted to react with a component selected from the group consisting of acetaldehyde, arsenic, benzo[a]pyrene, cadmium, crotonaldehyde, formaldehyde, nicotine, nicotine-derived nitrosamine ketone (NNK), N-nitrosonornicotine (NNN), derivatives thereof, decomposition products thereof, precursors thereof, and combinations thereof. 
     
     
         16 . The pouched product of  claim 1 , wherein the release modifying agent is selected from the group consisting of adsorbents, absorbents, molecularly imprinted polymers (MIPS), non-molecularly imprinted polymers (NIPS), botanicals, antioxidants, chelating agents, cyclodextrins, and combinations thereof. 
     
     
         17 . The pouched product of  claim 1 , wherein the composition within the cavity of the water-permeable fabric pouch comprises at least one of a particulate tobacco material, nicotine, particulate non-tobacco material treated to contain nicotine and/or flavoring agents, and fibrous plant material treated to contain a tobacco extract.
