Pouch made of a nonwoven, containing a tobacco material and/or a different nicotine-containing material

Abstract

A pouch includes a nonwoven that comprises a nicotine-containing material and at least partially comprising fibers. The fibers are based on cellulose. The nonwoven further includes a binder partially on a surface of the fibers, a plurality of compacted zones in a compacted state, and a plurality of non-compacted zones. The non-compacted zones are less compacted or uncompacted relative to the plurality of compacted zones. The binder keeps the plurality of compacted zones in the compacted state.

         14 . A pouch comprising:
 a nonwoven comprising a nicotine-containing material and at least partially comprising fibers, wherein the fibers are based on cellulose, the nonwoven further comprising,
 a binder partially on a surface of the fibers, 
 a plurality of compacted zones in a compacted state, and 
 a plurality of non-compacted zones, wherein the non-compacted zones are less compacted or uncompacted relative to the plurality of compacted zones, 
   wherein the binder keeps the plurality of compacted zones in the compacted state.   
     
     
         15 . The pouch according to  claim 14 , wherein the nonwoven comprises one of chemically bonded or a mechanically bonded nonwoven. 
     
     
         16 . The pouch according to  claim 14 , further comprising sealing seams, wherein mutually overlapping regions of the nonwoven are interconnected by a cross-linked binder. 
     
     
         17 . The pouch according to  claim 16 , wherein the cross-linked binder is simultaneously a chemical binder that chemically bonds the nonwoven. 
     
     
         18 . The pouch according to  claim 14 , wherein the nonwoven further comprises at least one of: (i) Cellulosic fibers; (ii) viscose fibers; (iii) cotton fibers; and (iv) polypropylene, polyethylenes, polyesters or other thermoplastic fibers. 
     
     
         19 . The pouch according to  claim 14 , wherein the nonwoven further comprises at least one of:
 a plurality of mutually separated compacted zones within a contiguous non-compacted zone;   a plurality of mutually separate non-compacted zones within a contiguous compacted zone;   a plurality of compacted zones and a plurality of non-compacted zones between the compacted zones; and   a single compacted zone and only a single non-compacted zone.   
     
     
         20 . The pouch according to  claim 14 , wherein at least one of the plurality of compacted zones and the plurality of non-compacted zones comprise one or more of the following shapes: polygonal; circular; oval; cruciform; strip-shaped; and wavy. 
     
     
         21 . The pouch according to  claim 14 , further comprising:
 a sealing seam running in a longitudinal direction on one large-area side in an overlap region of the nonwoven; and   sealing seams running in a transverse direction on two transverse sides in the overlap regions of the nonwoven.   
     
     
         22 . The pouch according to  claim 14 , wherein the plurality of compacted zones occupy 5% to 95% of a surface area of the nonwoven, and wherein the non-compacted zones occupy 95% to 5% of a surface area of the nonwoven. 
     
     
         23 . The pouch according to  claim 14 , wherein the nonwoven comprises at least one of:
 (i) a strength, in a machine direction, of 10 to 100 N/50 mm;   (ii) a strength, transverse to the machine direction, of 5 to 50 N/50 mm;   (iii) an elongation, in the machine direction, of 5 to 50%;   (iv) an elongation, transverse to the machine direction, of 10 to 100%; and   (v) a permeability, measured as an air permeability of a test surface of 5 cm 2 , of 1,000 to 2,250 L/m 2 /s, to which normal pressure is applied on one side, and to which an overpressure of 125 Pa is applied on another side.   
     
     
         24 . A method for producing a pouch comprising a nonwoven including a nicotine-containing material, comprising:
 moving a web material comprised of a nonwoven including fibers based on cellulose and a binder between an engraving roller having one or more projections on an outer periphery and a smooth roller;   pressing the engraving roller and the smooth roller against the web material from different sides and running in a circumferential direction on the web material,   compacting the web material in zones between the engraving roller and the smooth roller by one or more projections, wherein the web material located in zones between regions of the engraving roller that have no projections and the smooth roller is compacted to a lesser extent or not at all;   interconnecting the fibers of the web material by the binder in compacted zones; and   forming pouches from portions of the nicotine-containing material and severed sections of the web material.   
     
     
         25 . The method according to  claim 24 , wherein the engraving roller comprises an exchangeable embossing sleeve including one or more projections on an outer periphery. 
     
     
         26 . The method according  claim 24 , further comprising:
 feeding the nicotine-containing material onto the web material;   folding the web material above the portions, wherein a sealing seam extends in a longitudinal direction and is made in overlapping edge regions of the web material;   forming transversely directed sealing seams into mutually overlapping regions of the web material on both sides of each portion of the nicotine containing material; and   cutting the web material into individual pouches within the transverse sealing seams.
