Aerosol Generating Article with Shaped Multi-Textured Filter

Abstract

A filter for an aerosol generating article includes a first end for attachment to an aerosol generating article; a second end which is a mouth end which can be received in the mouth of a user; and tipping paper wrapped around the filter. The tipping paper provides four haptic regions which provide different touch experiences for a user's lips at the mouth end, wherein first and second haptic regions provide a first touch experience and third and fourth haptic regions provide a second touch experience. Rotation of the filter allows different haptic regions to contact the user's lips, and haptic regions arranged on opposing sides of the filter may provide a same or different touch experience for both the upper and lower lip of the user.

1 . A filter for an aerosol generating article, the filter comprising:
 a first end for attachment to an aerosol generating article;   a second end which is a mouth end which can be received in a mouth of a user; and   tipping paper wrapped around the filter,   wherein the tipping paper provides first, second, third, and fourth haptic regions which provide different touch experiences for a user's lips at the mouth end,   wherein the first and second haptic regions provide a first touch experience, and the third and fourth haptic regions provide a second touch experience, and   wherein a rotation of the filter allows different ones of the first, second, third, and fourth haptic regions to contact the user's lips.   
     
     
         2 . The filter of  claim 1 , wherein the first, second, third, and fourth haptic regions provide different touch experiences using one or more of: perforations, textured tipping paper, embossing, debossing, and surface smoothness. 
     
     
         3 . The filter of  claim 1 , wherein the first haptic region is provided opposite the second haptic region and the third haptic region is provided opposite the fourth haptic region at the mouth end. 
     
     
         4 . The filter of  claim 1 , wherein haptic regions of the first, second, third, and fourth haptic regions arranged on opposing sides of the filter provide a same touch experience for both upper and lower lips of the user. 
     
     
         5 . The filter of  claim 1 , wherein haptic regions of the first, second, third, and fourth haptic regions arranged on opposing sides of the filter provide a different touch experience. 
     
     
         6 . The filter of  claim 1 , wherein the filter can be rotated through 90 degrees to move between the first touch experience and the second touch experience. 
     
     
         7 . The filter of  claim 6 , wherein the mouth end has a cross-sectional shape with a plurality of flat sides. 
     
     
         8 . The filter of  claim 7 , wherein the cross-sectional shape of the mouth end is a rounded square, wherein the first, second, third, and fourth haptic regions are provided respectively on the four sides of the rounded square. 
     
     
         9 . The filter of  claim 1 , wherein the first end has a cross-sectional shape that is substantially circular to match a cross-sectional shape of an aerosol generating device. 
     
     
         10 . The filter of  claim 1 , wherein the mouth end comprises a hollow filter segment. 
     
     
         11 . An aerosol generating article comprising a charge of tobacco containing substrate and the filter according to  claim 1  attached at an aerosol delivery end of said charge. 
     
     
         12 . The aerosol generating article of  claim 11 , wherein the charge of tobacco containing substrate comprises reconstituted tobacco. 
     
     
         13 . The aerosol generating article of  claim 11 , wherein the charge of tobacco containing substrate comprises extruded or moulded tobacco containing substrate elements. 
     
     
         14 . The aerosol generating article of  claim 11 , wherein the charge of tobacco containing substrate comprises tobacco cut-filler.
