Additive-containing member

Abstract

An additive-containing member having first and second regions, the second region comprising a predetermined region ( 5 ) 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 ( 1,2 ) of the additive-containing member.

1 . 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 configured 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. 
     
     
         2 . The additive-containing member as claimed in  claim 1 , wherein the two parts of the additive-containing member are substantially parallel planar parts. 
     
     
         3 . The additive-containing member as claimed in  claim 1 , wherein the predetermined region is substantially linear. 
     
     
         4 . The additive-containing member as claimed in  claim 1 , wherein the predetermined region is a corner region. 
     
     
         5 . The additive-containing member as claimed in  claim 1 , and comprising a polymeric material. 
     
     
         6 . The additive-containing member as claimed in  claim 1 , wherein the seal comprises a weld between the two parts. 
     
     
         7 . (canceled) 
     
     
         8 . An arrangement of smoking article additive-containing members, comprising a plurality of additive-containing members and an elongate connecting member connecting the additive-containing members together, wherein at least one of said plurality of 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 additive-containing member, thereby releasing additive. 
     
     
         9 . The arrangement as claimed in  claim 8 , wherein an edge of at least one of said plurality of additive-containing members is formed at an acute angle with respect to the length of the elongate connecting member, thereby defining said predetermined region. 
     
     
         10 . The arrangement as claimed in  claim 8 , wherein the elongate connecting member comprises a tape. 
     
     
         11 . The arrangement as claimed in  claim 8 , wherein the elongate connecting member comprises two layers sealed together to form pocket regions for containing additive. 
     
     
         12 . 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 additive-containing members and an elongate connecting member connecting the additive-containing members together, wherein at least one of said plurality of 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 additive-containing member, thereby releasing additive, wherein said segment includes one or more additive-containing members. 
     
     
         13 . A smoking article filter having a mouth end and a tobacco end, comprising 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 configured 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, and wherein said predetermined region is configured to direct additive towards a predetermined region of the filter. 
     
     
         14 . The smoking article as claimed in  claim 13 , wherein said predetermined region is configured to direct additive exclusively towards one of the tobacco end or the mouth end of the filter. 
     
     
         15 . The smoking article filter as claimed in  claim 13 , wherein said predetermined region is configured to direct additive towards the side of the filter. 
     
     
         16 . The smoking article filter as claimed in  claim 13 , wherein said additive-containing member is surrounded by filter material. 
     
     
         17 . The smoking article filter as claimed in  claim 13 , further comprising a first additive-containing member containing a first additive and a second additive-containing member containing a second additive different to the first additive. 
     
     
         18 . The additive-containing member as claimed in  claim 5 , wherein the polymeric material is polyvinyl alcohol. 
     
     
         19 . The additive-containing member as claimed in  claim 5 , wherein the polymeric material is polyethylene. 
     
     
         20 . The arrangement as claimed in  claim 8 , wherein the predetermined region is at a seal between two parts of at least one additive-containing member of said plurality of additive-containing members.
