Smoking Article and Manufacturing Method for a Smoking Article

Abstract

This invention relates to a smoking article ( 1 ) and to a method for manufacturing a smoking article. The smoking article comprises a smoking material rod ( 2 ), at least one filtering element ( 3 ) and a wrapper ( 4 ), said wrapper connects the at least one filtering element and the smoking material rod; the smoking material rod and the at least one filtering element are spaced apart and this space is enclosed by the wrapper to form a chamber ( 6 ); and the wrapper comprises at least one ventilation opening ( 5 ).

1 . A smoking article comprising a smoking material rod, at least one filtering element and a wrapper, wherein:
 said wrapper connects the at least one filtering element and the smoking material rod;   the smoking material rod and the at least one filtering element are spaced apart and this space is enclosed by the wrapper to form a chamber; and   the wrapper comprises at least one ventilation opening.   
     
     
         2 . A smoking article according to  claim 1 , wherein the at least one ventilation opening is located over the chamber. 
     
     
         3 . A smoking article according to  claim 1 , wherein the spacing between the smoking material rod and the filtering element is between 2 to 5 mm. 
     
     
         4 . A smoking article according to  claim 3 , wherein the spacing between the smoking material rod and the filtering element is between 2 to 3 mm. 
     
     
         5 . A smoking article according to  claim 1 , wherein the smoking material rod is a tobacco rod. 
     
     
         6 . A smoking article according to  claim 5 , wherein the extremity of the tobacco rod adjacent to the chamber comprises tobacco that is fastened to a tobacco rod liner. 
     
     
         7 . A smoking article according to  claim 6 , wherein the tobacco is fastened to the tobacco rod liner by means of an adhesive or by adjusting the quantity of tobacco on the tobacco rod extremities. 
     
     
         8 . A method for manufacturing a smoking article, comprising:
 providing a smoking material rod and at least one filtering element in a spaced apart relationship to form a space between the smoking material rod and the filter element; and   connecting the smoking material rod to the at least one filtering element by means of a wrapper comprising at least one ventilation opening, the wrapper enclosing the space between the smoking material rod and the at least one filtering element to form a chamber.   
     
     
         9 . A method according to  claim 8 , wherein spacing guides are installed in a closing drum of a filter coupling machine to form the space between the smoking material rod and the at least one filtering element. 
     
     
         10 . A method according to  claim 8 , wherein the smoking material rod is a tobacco rod. 
     
     
         11 . A method, according to  claim 10 , wherein the method further comprises the step of fastening tobacco located at the tobacco rod extremity adjacent to the chamber to a tobacco rod liner. 
     
     
         12 . A method of manufacturing a smoking article, comprising:
 providing a tobacco rod and at least one filtering element in a spaced apart relationship to form a space between the tobacco rod and the filter element,
 wherein the spacing between the tobacco rod and the filtering element is between 2 to 5 mm; 
   connecting the tobacco rod to the at least one filtering element by means of a wrapper comprising at least one ventilation opening, the wrapper enclosing the space between the smoking material rod and the at least one filtering element to form a chamber,
 wherein the at least one ventilation opening is located over the chamber 
 wherein spacing guides are installed in a closing drum of a filter coupling machine to form the space between the tobacco rod and the at least one filtering element; and 
   fastening tobacco located at the tobacco rod extremity adjacent to the chamber to a tobacco rod liner.
