Method for obtaining a fan-like brush

Abstract

A method for obtaining a brush for nails of “fan-like” type starting from a brush of “round” or “flat” type having a plastically deformable handle and whose hairs are partially housed in a seat made in the handle starting from one end thereof. In particular, the seat includes a cavity delimited by a base and a side wall. The hairs of the brush penetrate the cavity by traversing an opening opposite the base. The method consists of compressing the handle of the brush at a section thereof adjacent to the opening of the seat and arranged at a certain distance from the base. The compression has sufficient intensity to plastically deform the handle and cause a flattening of the hair housing seat due to which the hairs assume a divergent configuration. The brush thus becomes of “fan-like” type.

         11 . Method for obtaining a fan-like brush ( 20 ), said method comprising the steps of:
 a) arranging a brush ( 1 ) comprising:
 a plastically deformable handle ( 2 ); 
 a multiplicity ( 7 ) of hairs ( 6 ); 
 a seat obtained at one end ( 5 ) of said handle ( 2 ) for housing said hairs ( 6 ) and connecting said hairs ( 6 ) to said handle ( 2 ), 
   
       said seat comprising a substantially cylindrical cavity ( 11 ) accessible through a substantially circular opening ( 14 ), said cavity ( 11 ) being delimited by a substantially circular base ( 12 ) opposite said opening ( 14 ) and by at least one side wall ( 13 ) made of polyethylene and having a thickness of at least 2 mm, said hairs ( 6 ) penetrating said cavity ( 11 ), starting from said opening ( 14 ), at a first section ( 10 ) thereof;
 b) compressing said handle ( 2 ) transversely with respect to said side wall ( 13 ) and at a second section ( 21 ) adjacent to said opening ( 14 ) and placed at a predefined distance from said base ( 12 ), said second section ( 21 ) having a length not greater than  2 / 3  the distance between said opening ( 14 ) and said base ( 12 ),
 said compression being not less than 0.3 N/mm 2  and having intensity sufficient for plastically deforming said handle ( 2 ), increasing the eccentricity of said opening ( 14 ) and of said base ( 12 ), 
 said compression causing a flattening of said seat at least at said second section ( 21 ), 
 due to said flattening, said side wall ( 13 ) assuming, at least at said second section ( 21 ), a conformation that is diverging starting from said base ( 12 ), 
 said multiplicity ( 7 ) of hairs ( 6 ) coming to be compressed by said deformed side wall ( 13 ) so as to assume a conformation that is diverging starting from said base ( 12 ). 
 
 
     
     
         12 . Method according to  claim 11 , wherein said length of said second section ( 21 ) is not greater than ⅓ the distance between said opening ( 14 ) and said base ( 12 ). 
     
     
         13 . Method according to  claim 11 , wherein said polyethylene is a low-density polyethylene and said side wall ( 13 ) has a thickness not greater than 2 mm. 
     
     
         14 . Method according to  claim 13 , wherein said compression is not less than 0.6 N/mm 2 . 
     
     
         15 . Method according to  claim 11 , wherein said polyethylene is high-density polyethylene, said side wall ( 13 ) has a thickness not greater than 2 mm and said compression is not less than 0.5 N/mm 2 . 
     
     
         16 . Method according to  claim 15 , wherein said compression is not less than 1 N/mm 2 . 
     
     
         17 . Method according to  claim 11 , wherein
 said hairs ( 6 ) are folded on themselves so as to assume a V-shaped configuration;   said hairs ( 6 ) are grouped in said multiplicity ( 7 ) in a manner such that the vertices ( 9 ) of the Vs are at said base ( 12 ) and the concavities of the Vs are directed towards said opening ( 14 );   said brush ( 1 ) comprises a bracket ( 8 ) including at least one section linking said Vs, said linking section being integrally connected to said handle ( 2 ), said linking section being housed in said seat and being opposite said base ( 12 ) of said seat, said bracket ( 8 ) integrally connecting said hairs ( 6 ) to said handle ( 2 ),   
       said compression is obtained by applying a force ( 22 ) directed transverse to a plane where said linking section ( 8 ) lies. 
     
     
         18 . Method according to  claim 17 , wherein said bracket ( 8 ) includes two arms integrally connected, at a respective end, to said linking section at the ends of said linking section, said arms penetrating said handle ( 2 ) so as to integrally connect said linking section to said handle ( 2 ), said compression is obtained by applying a force ( 22 ) directed transverse to a plane where said linking section and said arms lie.
