Abstract

An additive release assembly, a filter for a smoking article, a smoking article and a method of manufacturing An additive release assembly ( 20 ) for a smoking article ( 10 ), comprising: a web ( 22 ) comprising a first sheet of material, and one or more discrete quantities of additive coupled to the first sheet material. The assembly is configured to permit selective release of the quantities of additive.

1 . An additive release assembly for a smoking article, comprising:
 a web comprising a first sheet of material and a second sheet of material, wherein the first and second sheets of material contain therebetween one or more discrete quantities of additive coupled to the first sheet material,   wherein the assembly is configured to permit selective release of the quantities of additive.   
     
     
         2 . The assembly as claimed in  claim 1  wherein the first sheet of material is laminated to the second sheet of material. 
     
     
         3 . The assembly as claimed in  claim 1 ,
 wherein the additive is contained within an at least one additive release component, and   wherein the at least one additive release component is secured between the first and second sheets of material.   
     
     
         4 . The assembly as claimed in  claim 1 , wherein the first sheet of material and second sheet of material define one or more sealed compartments containing the additive. 
     
     
         5 . The assembly as claimed in  claim 4 , wherein the first sheet of material defines one or more recesses defining the one or more sealed compartments, and wherein the second sheet of material is substantially planar and covers the recesses. 
     
     
         6 . The assembly as claimed in  claim 4 , wherein the additive is free or loose within the one or more compartments. 
     
     
         7 . The assembly as claimed in  claim 1  further comprising a third layer of sheet material, wherein the first and third sheets of material contain therebetween one or more discrete quantities of additive. 
     
     
         8 . The assembly as claimed in  claim 7 ,
 wherein the additive between the first and third layers is contained within an at least one additive release component, and   wherein the at least one additive release component is secured between the first and third sheets of material.   
     
     
         9 . A filter for a smoking article comprising:
 filtration material, and   an additive release assembly comprising:   a web comprising a first sheet of material and a second sheet of material, wherein the first and second sheets of material contain therebetween at least one discrete quantity of additive coupled to the first sheet material,   wherein the assembly is configured to permit selective release of the quantities of additive.   
     
     
         10 . The filter as claimed in  claim 9 , further comprising a covering layer forming an exterior surface of the filter,
 wherein the covering layer is transparent over at least a part of the filter such that the additive release component is visible.   
     
     
         11 . A smoking article comprising:
 an additive release assembly comprising:   a web comprising a first sheet of material and a second sheet of material, wherein the first and second sheets of material contain therebetween at least one or discrete quantity of additive coupled to the first sheet material,   wherein the assembly is configured to permit selective release of the quantities of additive.   
     
     
         12 . A method of manufacturing an additive release assembly for a smoking article, comprising:
 providing at least one quantity of additive,   providing a first sheet of material and a second sheet of material,   coupling the at least one quantity of additive to the first sheet, wherein the first and second sheets of material contain therebetween the one or more discrete quantities of additive, and   laminating the first sheet of material to the second sheet of material to form a web around the additive.   
     
     
         13 . The method as claimed in  claim 12 , further comprising:
 applying the first sheet of material to a rotatable carousel having a plurality of receptacles,   inserting an additive release component containing the additive into a receptacle on which the first sheet of material has been applied; and   applying the second sheet of material to the receptacle in which said additive release component is inserted.   
     
     
         14 . The method as claimed in  claim 12 , further comprising:
 forming one or more pockets in the first sheet of material providing an additive to at least one of the one or more pockets, and   affixing the first sheet of material to the second sheet of material to secure the additive within the pocket and form a web extending beyond the pocket.
