   (i) the portions made of different materials each defining a part of the outer perimeter p of the fibre in section, or   (ii) one of the portions made of different materials entirely surrounding the other in section and having at least one region that narrows towards the outside.   
     
     
         16 . The device according to  claim 15 , wherein each fibre has between 2 and 8 of said portions. 
     
     
         17 . The device according to  claim 15 , wherein each fibre has between 2 and 8 portions made of different materials. 
     
     
         18 . The device according to  claim 15 , wherein the portions are co-extruded. 
     
     
         19 . The device according to  claim 15 , wherein the portions have a constant section and extend longitudinally along the entire length of the fibre. 
     
     
         20 . The device according to  claim 19 , wherein the portions are continuous along the entire length of the fibre. 
     
     
         21 . The device according to  claim 15 , wherein said portions made of different materials have a difference of at least 10 units on the same Shore hardness scale. 
     
     
         22 . The device according to  claim 21 , wherein said portions made of different materials have a difference of at least 20 units. 
     
     
         23 . The device according to  claim 15 , wherein said portions each occupy, in cross section, between 20% and 80% of the section formed by the joining of this portion to an adjacent portion made of a different material. 
     
     
         24 . The device according to  claim 23 , wherein said portions each occupy, in cross section, between 30% and 70% of the section formed by the joining of this portion to an adjacent portion made of a different material. 
     
     
         25 . The device according to  claim 23 , wherein said portions each occupy, in cross section, between 40% and 60% of the section formed by the joining of this portion to an adjacent portion made of a different material. 
     
     
         26 . The device according to  claim 15 , wherein two of said portions made of different materials are separated, in cross section, by a contact line with a length greater than or equal to 1/16 of the perimeter of the area formed by the joining of these portions. 
     
     
         27 . The device according to  claim 26 , wherein two of said portions made of different materials are separated, in cross section, by a contact line with a length greater than or equal to ⅛ of the perimeter of the area formed by the joining of these portions. 
     
     
         28 . The device according to  claim 15 , wherein each fibre has a shape factor L/e less than or equal to 5, the shape factor L/e being defined in section by the ratio of the greatest length L of the fibre to the greatest dimension e of the fibre in a direction perpendicular to that of the greatest length L. 
     
     
         29 . The device according to  claim 28 , wherein each fibre has a shape factor L/e less than or equal to 4. 
     
     
         30 . The device according to  claim 15 , wherein the fibres have, in cross section, a region that narrows towards the outside. 
     
     
         31 . The device according to  claim 15 , wherein at least two separated portions are made of one and the same material. 
     
     
         32 . The device according to  claim 15 , wherein the applicator has a core formed by a metal strand folded on itself and twisted, the fibres being clamped between the strands of the core. 
     
     
         33 . A makeup method comprising the step of applying a makeup product to human keratin materials with the packaging and application device according to  claim 15 . 
     
     
         34 . A method for manufacturing a device according to  claim 15 , comprising the step of heating the applicator member so as to bring about the deformation of the fibres.
