Additive - containing member

Abstract

Smoking article additive-containing member An additive-containing member having first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is caused to break when pressure is applied to the additive-containing member, thereby to release additive, wherein the predetermined region is at a seal between two parts of the additive-containing member.

         18 . A smoking article additive-containing member configured for use in a smoking article, the smoking article additive-containing member having first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is configured to break when pressure is applied to the smoking article additive-containing member, thereby to release smoking article additive, wherein the predetermined region is at a seal between two parts of the smoking article additive-containing member. 
     
     
         19 . The smoking article additive-containing member as claimed in  claim 18 , wherein the two parts of the smoking article additive-containing member are substantially parallel planar parts. 
     
     
         20 . The smoking article additive-containing member as claimed in  claim 18 , wherein the predetermined region is substantially linear. 
     
     
         21 . The smoking article additive-containing member as claimed in  claim 18 , wherein the predetermined region is a corner region. 
     
     
         22 . The smoking article additive-containing member as claimed in  claim 18 , and comprising a polymeric material. 
     
     
         23 . The smoking article additive-containing member as claimed in  claim 22 , wherein the polymeric material is polyvinyl alcohol. 
     
     
         24 . The smoking article additive-containing member as claimed in  claim 22 , wherein the polymeric material is polyethylene. 
     
     
         25 . The smoking article additive-containing member as claimed in  claim 18 , wherein the seal comprises a weld between the two parts. 
     
     
         26 . An arrangement of smoking article additive-containing members, comprising a plurality of smoking article additive-containing members and an elongate connecting member connecting the smoking article additive-containing members together, wherein at least one of said plurality of smoking article additive-containing members comprises first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is configured to break when pressure is applied to the smoking article additive-containing member, thereby releasing smoking article additive, and wherein the predetermined region is at a seal between two parts of the smoking article additive-containing member. 
     
     
         27 . The arrangement as claimed in  claim 26 , wherein an edge of at least one of said plurality of smoking article additive-containing members is formed at an acute angle with respect to the length of the elongate connecting member, thereby defining said predetermined region. 
     
     
         28 . The arrangement as claimed in  claim 26 , wherein the elongate connecting member comprises a tape. 
     
     
         29 . The arrangement as claimed in  claim 26 , wherein the elongate connecting member comprises two layers sealed together to form pocket regions for containing smoking article additive. 
     
     
         30 . A filter rod for use in the manufacture of smoking articles, comprising a segment of an arrangement of smoking article additive-containing members, said arrangement comprising a plurality of smoking article additive-containing members and an elongate connecting member connecting the smoking article additive-containing members together, wherein at least one of said plurality of smoking article additive-containing members comprises first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is configured to break when pressure is applied to the smoking article additive-containing member, thereby releasing smoking article additive, wherein the predetermined region is at a seal between two parts of the smoking article additive-containing member, and wherein said segment includes one or more smoking article additive-containing members. 
     
     
         31 . A smoking article filter having a mouth end and a tobacco end, comprising a smoking article additive-containing member having first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is configured to break when pressure is applied to the smoking article additive-containing member, thereby to release smoking article additive, wherein the predetermined region is at a seal between two parts of the smoking article additive-containing member, and wherein said predetermined region is configured to direct smoking article additive towards a predetermined region of the filter. 
     
     
         32 . The smoking article as claimed in  claim 31 , wherein said predetermined region is configured to direct smoking article additive exclusively towards one of the tobacco end or the mouth end of the filter. 
     
     
         33 . The smoking article filter as claimed in  claim 31 , wherein said predetermined region is configured to direct smoking article additive towards the side of the filter. 
     
     
         34 . The smoking article filter as claimed in  claim 31 , wherein said smoking article additive-containing member is surrounded by filter material. 
     
     
         35 . The smoking article filter as claimed in  claim 31 , further comprising a first smoking article additive-containing member containing a smoking article first additive and a second smoking article additive-containing member containing a second additive different to the first additive.
