         3 . The blank according to  claim 1 , wherein said width of said recess supporting tab is gradually reduced from a portion having said maximum width toward said base end portion. 
     
     
         4 . The blank according to  claim 2 , wherein said one side portion is abutted to said edge portion of said article receiving opening. 
     
     
         5 . The blank according to  claim 2 , wherein an end portion of said slit on a side adjacent to said one end of said tab folding line extends to a position dividing said tab folding line and said first panel folding line, and
 wherein said one side portion of said recess supporting tab forms a foldable ear potion with respect to a residual portion of said recess supporting tab by said slit.   
     
     
         6 . The blank according to  claim 5 , wherein said foldable ear potion is connected to said recess supporting tab via an ear potion folding line. 
     
     
         7 . The blank according to  claim 5 , wherein said end portion of said slit is curved toward said tab folding line. 
     
     
         8 . A carton for housing articles with a substantially cylinder shape having a recess portion on at least one end of said article, wherein said carton comprising:
 a first wall;   a second wall at least connected to said first wall via a first panel folding line;   wherein said first panel has an article holding means for holding said article;   wherein said article holding means comprises an article receiving opening for receiving a portion of said article and a recess supporting tab provided to protrude toward said article receiving opening;   wherein a base end portion of said recess supporting tab is connected to said first wall via a tab folding line; and   wherein a width (W 2 ) of said base end portion of said recess supporting tab is equal to or less than a maximum width (W 1 ) of said recess supporting tab.   
     
     
         9 . The carton according to  claim 8 , wherein a boundary between at least one side portion of said recess supporting tab and an edge portion of said article receiving opening is formed with a slit, and said slit extends from one end of said tab folding line to a free end of said recess supporting tab. 
     
     
         10 . The carton according to  claim 8 , wherein said width of said recess supporting tab is gradually reduced from a portion having said maximum width toward said base end portion. 
     
     
         11 . The carton according to  claim 9 , wherein said one side portion is abutted to said edge portion of said article receiving opening. 
     
     
         12 . The carton according to  claim 9 , wherein an end portion of said slit on a side adjacent to said one end of said tab folding line extends to a position dividing said tab folding line and said first panel folding line, and
 wherein said one side portion of said recess supporting tab forms a foldable ear potion with respect to a residual portion of said recess supporting tab by said slit.   
     
     
         13 . The carton according to  claim 12 , wherein said foldable ear potion is connected to said recess supporting tab via an ear potion folding line. 
     
     
         14 . The carton according to  claim 12 , wherein said end portion of said slit is curved toward said tab folding line.
