Fluid product dispenser with flexible pouch and method for producing one such flexible pouch

Abstract

A fluid dispenser comprising: a variable-capacity deformable flexible pouch ( 1 ) provided with an opening ( 121 ); a flexible pouch support ( 2 ) to which the opening ( 121 ) in the flexible pouch ( 1 ) is fixed, said support having a fixing surface ( 212 ) at which the flexible pouch is fixed to the support; and a dispensing member ( 3 ) such as a pump or a valve, mounted on the pouch support ( 2 ) for drawing fluid from the pouch; said dispenser being characterized in that the fixing surface ( 212 ) is substantially plane, so that it extends in one plane.

1 / A fluid dispenser comprising: 
 a variable-capacity deformable flexible pouch ( 1 ) provided with an opening ( 121 );    a flexible pouch support ( 2 ) to which the opening ( 121 ) in the flexible pouch ( 1 ) is fixed, said support having a fixing surface ( 212 ) at which the flexible pouch is fixed to the support; and    a dispensing member ( 3 ) such as a pump or a valve, mounted on the pouch support ( 2 ) for drawing fluid from the pouch;    said dispenser being characterized in that the fixing surface ( 212 ) is substantially plane, so that it extends in one plane.    
     
     
         2 / A dispenser according to  claim 1 , in which the fixing surface ( 212 ) is annular.  
     
     
         3 / A dispenser according to  claim 1  or  2 , in which the support ( 2 ) comprises a substantially tubular sleeve ( 22 ) having a longitudinal axis (A), the dispensing member ( 3 ) extending in said sleeve ( 22 ), the plane of the fixing surface ( 212 ) being perpendicular to said longitudinal axis (A).  
     
     
         4 / A dispenser according to any preceding claim, in which the fixing surface ( 212 ) is formed by one face of an annular, plane, thin flange ( 21 ) disposed inside the pouch ( 1 ) around the opening ( 121 ) therein.  
     
     
         5 / A dispenser according to any preceding claim, in which the flexible pouch ( 1 ) is made up of two flexible pouches ( 11 ,  12 ) that are sealed together over their peripheries, along a sealing line ( 112 ), the opening ( 121 ) in the flexible pouch being situated in one of the sheets ( 12 ).  
     
     
         6 / A dispenser according to  claim 5 , in which the opening ( 121 ) is situated substantially at the center of one of the sheets ( 12 ).  
     
     
         7 / A dispenser according to  claim 5 , in which the sealing line ( 112 ) along which the two sheets ( 11 ,  12 ) are sealed together extends in a plane substantially parallel to the plane of the fixing surface ( 212 ) of the pouch support ( 2 ).  
     
     
         8 / A dispenser according to  claim 3 , in which the empty flexible pouch ( 1 ) has a thickness that is almost zero along the longitudinal axis (A).  
     
     
         9 / A dispenser according to  claim 1 , in which the flexible pouch ( 1 ) is wedged in leaktight manner between the pouch support ( 2 ) and a bearing element ( 41 ).  
     
     
         10 / A method of manufacturing a flexible pouch ( 1 ) provided with a flexible pouch support ( 2 ), said method comprising the following steps: 
 cutting out two substantially identical sheets ( 11 ,  12 ), each of which has a periphery;    cutting an opening ( 121 ) through one of the two sheets ( 12 ) advantageously at its center;    fixing the pouch support ( 2 ) to the sheet ( 12 ) provided with the opening ( 121 ) so that it extends through the opening; and    fixing the other flexible sheet ( 11 ) to the sheet ( 12 ) provided with the opening around their peripheries.    
     
     
         11 / A method according to  claim 10 , in which the support ( 2 ) serves to cut the opening ( 121 ) through the sheet ( 12 ), advantageously by punching out.
