Smoking Article and Method for Manufacturing a Smoking Article

Abstract

A smoking article includes a cylindrical shape with a longitudinal axis running through respective base areas of a distal end and a mouth end of the smoking article, wherein the smoking article includes the following segments, which are arranged subsequently in the following order from the distal to the mouth end, and are at least in part wrapped in a circumferential wrapper: a tobacco segment including tobacco or tobacco derived smokable material, a cooling segment including a cylindrically shaped cooler material having a first flow path from the tobacco segment to a filter segment, the filter segment including a second flow path from the cooling segment to the mouth end. A surface of the cooler material is at least in part coated with a tobacco product including tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco particles.

         4 . The smoking article according to  claim 3 , wherein:
 the pattern comprises circumferential rings with an extent in a direction along the longitudinal axis and distanced from each other along the longitudinal axis by a distance.   
     
     
         5 . The smoking article according to  claim 3 , wherein:
 the pattern comprises a varying layer thickness of the tobacco product on the surface.   
     
     
         6 . The smoking article according to  claim 1 , wherein:
 the cooling segment comprises a shape of a hollow cylinder having an inner lateral area enclosing a through-hole through which the first flow path is arranged, wherein the first flow path is also parallel to the longitudinal axis, wherein the inner lateral area is at least in part coated with the tobacco product.   
     
     
         7 . The smoking article according to  claim 1 , wherein:
 the cooling segment comprises a shape of a hollow cylinder having an inner lateral area enclosing a through-hole through which the first flow path is arranged, wherein the first flow path is also parallel to the longitudinal axis, wherein an outer lateral area of the cooling segment is at least in part coated with the tobacco product.   
     
     
         8 . The smoking article according to  claim 6 , wherein:
 the cooling segment comprises ventilation holes, wherein the tobacco product is only arranged downstream of the ventilation holes.   
     
     
         9 . The smoking article according to  claim 6 , wherein:
 the cooling segment comprises ventilation holes, wherein the tobacco product is only arranged upstream of the ventilation holes.   
     
     
         10 . The smoking article according to  claim 6 , wherein:
 the cooling segment further comprises a flow diverter arranged in the through-hole of the cooling segment, wherein the flow diverter diverts the first flow-path directly to the tobacco product coated surface.   
     
     
         11 . The smoking article according to  claim 10 , wherein:
 the flow diverter is a protrusion of the filter segment protruding into the through-hole of the cooling segment.   
     
     
         12 . The smoking article according to  claim 10 , wherein:
 the flow diverter is a loose element arranged inside the through-hole of the cooling segment comprising a shape of a sphere or prolate spheroid arranged with a longest axis thereof parallel to the longitudinal axis.   
     
     
         13 . The smoking article according to  claim 1 , wherein:
 the cooling segment comprises multiple parallel first flow-paths each being circumferentially enclosed by a respective part of the surface of the cooling segment, wherein the respective parts of the surface are at least in part coated with the tobacco product.   
     
     
         14 . A method for manufacturing a smoking article, wherein a tobacco segment comprising tobacco or tobacco derived smokable material, a cooling segment comprising a cylindrically shaped cooler material having a first flow path and a filter segment comprising a second flow path are arranged in the given order subsequently on a longitudinal axis and are at least in part wrapped in a circumferential wrapper thereby forming the smoking article having a cylindrical shape with the longitudinal axis running through respective base areas of the smoking article being a distal end, at which the tobacco segment is arranged, and a mouth end, at which the filter segment is arranged, respectively, wherein the first flow path connects the tobacco segment with the filter segment and the second flow path connects the cooling segment with the mouth end,
 wherein before arranging the cooling segment between the tobacco segment and the filter segment, a surface of the cooler material is at least in part coated with a tobacco product comprising tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco particles.   
     
     
         15 . The method according to  claim 14 , wherein:
 the tobacco product is applied to the surface of the cooler material by spraying or printing.
