Assembly device for mounting a dispensing element to the neck of a container

Abstract

Mounting equipment ( 1 ) for mounting a dispenser member ( 3 ) on a neck ( 22 ) of a receptacle ( 2 ) by force-fitting, the neck presenting an axis of symmetry (X), said equipment including a thrust member ( 14 ) that is capable of exerting thrust on the dispenser member ( 3 ) so as to force-fit it on the receptacle neck, the equipment being characterized in that it further includes: a first guide wall ( 128 ) for bringing the dispenser member at least approximately onto the axis (X) of the neck ( 22 ); and a second guide wall ( 148 ) for bringing the dispenser member more accurately onto the axis of the neck.

1 . Mounting equipment ( 1 ) for mounting a dispenser member ( 3 ) on a neck ( 22 ) of a receptacle ( 2 ) by force-fitting, the neck presenting an axis of symmetry (X), said equipment including a thrust member ( 14 ) that is capable of exerting thrush on the dispenser member ( 3 ) so as to force-fit it on the receptacle neck, the equipment being characterized in that it further includes: 
 a first guide wall ( 128 ) for bringing the dispenser member at least approximately onto the axis (X) of the neck ( 22 ); and    a second guide wall ( 148 ) for bringing the dispenser member more accurately onto the axis of the neck.    
   
   
       2 . Mounting equipment according to  claim 1 , in which the second guide wall ( 148 ) is formed by the thrust member ( 14 ).  
   
   
       3 . Mounting equipment according to  claim 1  or  claim 2 , in which the second guide wall ( 148 ) is displaceable relative to the first guide wall ( 128 ) between a rest position and a thrust position.  
   
   
       4 . Mounting equipment according to  claim 1 , in which the first guide wall ( 128 ) is frustoconical, at least in part, and coverges towards the second guide wall ( 148 ).  
   
   
       5 . Mounting equipment according  claim 1 , including a third guide wall ( 127 ) to perfect the alignment of the dispenser member with the axis of the neck.  
   
   
       6 . Mounting equipment according to  claim 5 , in which the second guide wall ( 148 ) is displaceable relative to the third guide wall ( 127 ) between a rest position and a thrust position, the third guide wall ( 127 ) being masked in the rest position, and unmasked in the thrust position.  
   
   
       7 . Mounting equipment according to  claim 5 , in which the thrust member ( 14 ) progressively unmasks the third guide wall ( 127 ), while moving from its rest position to its thrust position; the first guide wall and the third guide wall are secured to each other and static relative to each other.  
   
   
       8 . Mounting equipment according to claims  5 , in which the first guide wall ( 128 ) and the third guide wall ( 127 ) are secured to each other and static relative to each other.  
   
   
       9 . Mounting equipment according to  claim 8 , in which the first guide wall ( 128 ) is frustoconical, at least in part, and is extended by a substantially cylindrical portion forming the third guide wall ( 127 ).  
   
   
       10 . Mounting equipment according of claims  3 , in which the thrust member ( 14 ) is urged towards its rest position by resilient return means ( 13 ).  
   
   
       11 . Mounting equipment according to  claim 1 , in which the thrust member ( 14 ) forms a bushing ( 147 ) including an inside wall that is cylindrical, at least in part, and a free bottom end ( 149 ), the inside wall forming the second guide wall ( 148 ), and the free bottom end forming a contact zone adapted to come into thrust contact with the dispenser member ( 3 ).  
   
   
       12 . Mounting equipment according to claims  5 , in which, in the rest position, the bushing ( 147 ) masks the third guide wall ( 127 ).
