Electronic cigarette filler and electronic cigarette cartridge

Abstract

An electronic cigarette cartridge suitable for electronic cigarettes includes an aerosol-forming substrate having a filler enclosed by a wrapping member on one end and a mouthpiece on the other end. The filler is a sheet-like member having an aerosol former. The sheet-like member is filled so as to form an air passage in the longitudinal direction of the electronic cigarette cartridge. The sheet-like member has cuts along the longitudinal direction of the electronic cigarette cartridge.

1 . An electronic cigarette filler, comprising a sheet-like member, wherein
 the sheet-like member contains an aerosol former which generates an aerosol when the aerosol former is heated,   a longitudinal direction of an electronic cigarette is represented as a first direction, and   a plurality of cuts are made in only one surface of the sheet-like member along the first direction to a depth that does not penetrate the sheet-like member.   
     
     
         2 . The electronic cigarette filler according to  claim 1 , wherein the cuts are regularly arranged. 
     
     
         3 . The electronic cigarette filler according to  claim 1 , wherein
 the sheet-like member has a rectangular shape as a whole, and   the cuts are extended from one of four sides of the rectangular shape.   
     
     
         4 . The electronic cigarette filler according to  claim 3 , wherein
 a direction perpendicular to the first direction and along the surface of the sheet-like member is represented as a second direction, and   the cuts include first cuts that are made along the first direction from the one of four sides of the rectangular shape of the sheet-like member extending in the second direction.   
     
     
         5 . The electronic cigarette filler according to  claim 4 , wherein
 the cuts include second cuts that are made along the first direction from another side of four sides of the rectangular shape of the sheet-like member, and   the first cuts and the second cuts are arranged alternately in the second direction.   
     
     
         6 . The electronic cigarette filler according to  claim 1 , wherein
 a direction perpendicular to the first direction and along the surface of the sheet-like member is represented as a second direction, and   the cuts are arranged such that a length of a first direction component thereof is longer than a length of a second direction component.   
     
     
         7 . The electronic cigarette filler according to  claim 1 , wherein
 the filler is fixed to the inside of a wrapping member.   
     
     
         8 . The electronic cigarette filler according to  claim 1 , wherein
 the filler is filled so as to form an air passage in the first direction.   
     
     
         9 . The electronic cigarette filler according to  claim 8 , wherein
 the sheet-like member is folded or rolled to form the air passage.   
     
     
         10 . The electronic cigarette filler according to  claim 1 , wherein
 the filler has an end shape with an area that is substantially uniform as viewed from one end.   
     
     
         11 . The electronic cigarette filler according to  claim 1 , wherein
 the filler has an end shape with an area that increases from center to periphery as viewed from one end.   
     
     
         12 . The electronic cigarette filler according to  claim 1 , wherein
 a direction perpendicular to the first direction and along the surface of the sheet-like member is represented as a second direction,   the cuts are provided at a predetermined interval in the second direction,   the sheet-like member is continuous in an entire area thereof by a non-cut portion, and   when the sheet-like member is used for an aerosol-forming substrate, the cuts are provided on one end side and another end side of the aerosol-forming substrate.   
     
     
         13 . An electronic cigarette cartridge, comprising:
 the electronic cigarette filler according to  claim 1 ;   a lid which is arranged on the upstream side of the electronic cigarette filler;   a support element which is arranged on the downstream side of the electronic cigarette filler, the support element having a through hole for air flow in a center of the support element; and   a transfer member which is arranged on downstream side of the support element, the transfer member having a hollow tubular member.   
     
     
         14 . The electronic cigarette filler according to  claim 1 , wherein
 length of the cuts is 20% or more and 90% or less of length of the sheet-like member in the first direction.   
     
     
         15 . The electronic cigarette filler according to  claim 1 , wherein
 the plurality of cuts function as a passage of air.   
     
     
         16 . The electronic cigarette cartridge filler according to  claim 13 , wherein
 the plurality of cuts function as a passage of air.
