Cover Member, Method of Producing One Such Member and Dispenser Comprising One Such Member

Abstract

A covering member ( 1 ) for mounting on a fastener ring ( 2 ), the ring and the covering member co-operating with each other to form a fastener device for fastening a dispenser system ( 3 ), such as a pump or a valve, on a receptacle neck ( 40 ), the covering member presenting a general configuration that is substantially cylindrical and that includes an outside wall ( 14 ) and an inside wall ( 15 ) for coming into clamping contact around the ring ( 2 ), the inside wall forming an array of grooves ( 16, 17 ) hollowed out in a base zone ( 151 ), the grooves extending in at least two different directions.

1 . A covering member ( 1 ) for mounting on a fastener ring ( 2 ), the ring and the covering member co-operating with each other to form a fastener device for fastening a dispenser system ( 3 ), such as a pump or a valve, on a receptacle neck ( 40 ), the covering member presenting a general configuration that is substantially cylindrical and that includes an outside wall ( 14 ) and an inside wall ( 15 ) for coming into clamping contact around the ring ( 2 ), the inside wall forming an array of grooves ( 16 ,  17 ) hollowed out in a base zone ( 151 ), the covering member being characterized in that the grooves extend in at least two different directions. 
   
   
       2 . A covering member according to  claim 1 , in which at least two grooves ( 16 ,  17 ) cross in such a manner as to form at least one intersection ( 18 ) of grooves. 
   
   
       3 . A covering member according to  claim 1 , in which one fraction of the grooves ( 16 ) extends in a first direction, and another fraction of the grooves ( 17 ) extends in a second direction that is transverse to the first direction. 
   
   
       4 . A covering member according to  claim 1 , in which the grooves extend in such a manner as to form a grid of lozenge shapes. 
   
   
       5 . A covering member according to  claim 1 , in which the grooves extend in a repetitive pattern. 
   
   
       6 . A covering member according to  claim 1 , in which the grooves are formed by displacing material, such that the grooves are bordered by lumps of displaced material that project from the base zone ( 151 ). 
   
   
       7 . A method of manufacturing a covering member according to  claim 1 , the method comprising the following steps:
 a) making a covering member by stamping metal; and   b) machining the grooves by removing material.   
   
   
       8 . A method of manufacturing a covering member according to  claim 5 , the method comprising the following steps:
 a) making a covering member by stamping metal; and   b) machining the grooves by displacing material.   
   
   
       9 . A fluid dispenser comprising a receptacle, a dispenser system, and a fastener device that integrates a covering member according to any preceding claim. 
   
   
       10 . A fluid dispenser according to  claim 9 , in which the base ( 151 ) presents an inside diameter that is slightly less than the outside diameter of the fastener ring, such that the material constituting the ring creeps into the array of grooves.
