Supporting member for heated tobacco and cartridge for heated tobacco

Abstract

A supporting member for tobacco heating which adjusts the shape and the arrangement of the hole and a cartridge for tobacco heating, are provided. A supporting member for tobacco heating 12 which is provided in between a cigarette filling aggregate 10 and an inhalation opening 14 of a cartridge for tobacco heating 1 , the supporting member for tobacco heating 12 comprising: a first end surface 30 ; a second end surface 31 ; and a peripheral surface portion 32 : wherein a hole 40 running through from the first end surface 30 to the second end surface 31 is formed, and the hole 40 has, on the first end surface 30 or the second end surface 31 , a first through-hole 41 arranged so as not to include a central axis C of the peripheral surface portion 32.

What is claimed is: 
     
         1 . A supporting member for tobacco heating, comprising:
 a first end surface;   a second end surface;   a peripheral surrounding surface portion; and   a hole defined in said supporting member running through from said first end surface to said second end surface;   wherein said supporting member is in place in between a cigarette filling aggregate and an inhalation opening of a cartridge for tobacco heating, and   said hole further comprising:
 at least one first through-hole placed outside a central axis of said peripheral surrounding surface portion relative to respective said first end surface and said second end surface. 
   
     
     
         2 . The supporting member for tobacco heating, according to  claim 1 , wherein:
 a plurality of said first through-holes are in place along a peripheral surrounding direction relative to respective said first end surface and said second end surface.   
     
     
         3 . The supporting member for tobacco heating, according to  claim 1 , wherein:
 said at least one first through-hole, further comprises:
 an elliptic arc having a center thereof that is on a circle having a constant radius from said central axis of said peripheral surrounding surface portion as at least a part thereof relative to respective said first end surface and said second surface. 
   
     
     
         4 . The supporting member for tobacco heating, according to  claim 3 , wherein:
 said at least one through-hole further comprises:
 said elliptic arc in an outer peripheral side relative to respective said first end surface and said second end surface. 
   
     
     
         5 . The supporting member for tobacco heating, according to  claim 1 , wherein:
 said at least one through-hole further comprises:
 at least a second through-hole running from said first end surface to said second end surface and including said central axis of said peripheral surrounding surface portion. 
   
     
     
         6 . The supporting member for tobacco heating, according to  claim 1 , wherein:
 said peripheral surrounding surface portion further comprises at least one uneven element having an uneven form along said peripheral circumference direction; and   said uneven element is formed over an entire length in a length direction from said first end surface to said second end surface.   
     
     
         7 . The supporting member for tobacco heating, according to  claim 6 , wherein:
 a plurality of said uneven elements are formed over said entire circumference of said peripheral surrounding surface portion.   
     
     
         8 . A cartridge for tobacco heating, comprising:
 a cigarette filling aggregate;   an inhalation opening; and   a supporting member according to  claim 1  interposed in between said cigarette filling aggregate and said inhalation opening.
