Fluid dispenser

Abstract

A fluid dispenser comprising two sheets ( 1, 2 ) co-operating to define a fluid reservoir ( 15 ), at least one of the two sheets defining a deformable actuating wall ( 13, 23 ) on which it is possible to press to put the fluid under pressure in the reservoir, said fluid dispenser being characterized in that it further comprises a dispensing piece ( 3 ) to which at least one of the sheets is fixed, said piece defining a dispensing orifice ( 344 ) that is closed off by a removable closure member ( 4 ).

1 / A fluid dispenser comprising two sheets ( 1 ,  2 ) cooperating to define a fluid reservoir ( 15 ), at least one of the two sheets defining a deformable actuating wall ( 13 ,  23 ) on which it is possible to press to put the fluid under pressure in the reservoir, said fluid dispenser being characterized in that it further comprises a dispensing piece ( 3 ) to which at least one of the sheets is fixed, said piece defining a dispensing orifice ( 344 ) that is closed off by a removable closure member ( 4 ).  
     
     
         2 / A dispenser according to  claim 1 , in which the dispensing piece ( 3 ) comprises two side bars ( 36 ) which extend on either side of the dispensing orifice ( 31 ).  
     
     
         3 / A dispenser according to  claim 1 , in which the sheets ( 1 ,  2 ) are fixed together over a peripheral-margin of the reservoir along a sealing line that extends at least in part adjacently to the bars, with the bars being situated inside the reservoir.  
     
     
         4 / A dispenser according to  claim 2 , in which the bars ( 36 ) form a rigid inner side peripheral margin for the reservoir.  
     
     
         5 / A dispenser according to  claim 1 , in which the sheets ( 1 ,  2 ) are fixed to the bars to define a rigid outer peripheral margin for the reservoir.  
     
     
         6 / A dispenser according to  claim 2 , in which the bars ( 36 ) meet to form a closed frame.  
     
     
         7 / A dispenser according to  claim 1 , in which the dispensing orifice ( 344 ) opens out at an opening ( 25 ) provided in one of the sheets ( 2 ).  
     
     
         8 / A dispenser according to  claim 7 , in which the dispensing piece ( 3 ) is fixed to the sheet ( 2 ) around the periphery of the opening ( 25 ).  
     
     
         9 / A dispenser according to  claim 7 , in which the dispensing piece defines an outlet chamber ( 340 ) forming the outlet orifice and fed with fluid from the reservoir through radial channels ( 342 ).  
     
     
         10 / A dispenser according to  claim 7 ,  claim 8 , or  claim 9 , in which the dispensing orifice is formed at the bottom of a concave recovery dish ( 345 ) from which the fluid can be recovered by the user.  
     
     
         11 / A dispenser according to  claim 1 , in which the dispensing piece with its bars is received entirely within the reservoir, the sheets being fixed to each other around the dispensing piece.  
     
     
         12 / A dispenser according to  claim 9 , in which the radial channels ( 342 ) are separated by radial ribs ( 341 ) having an upper face in contact with the sheet ( 2 ).  
     
     
         13 / A dispenser according to  claim 1 , in which the dispensing piece ( 3 ) comprises a side facing the sheet ( 1 ) and an opposite side facing the sheet ( 2 ), the side facing the sheet ( 1 ) forming an outlet chamber ( 340 ), radial channels ( 342 ) connecting the chamber to the reservoir and radial ribs ( 341 ) separating the channels, the opposite side facing the sheet ( 2 ) forming a concave recovery dish ( 345 ) communicating with the chamber through the outlet orifice ( 344 ), the sheet ( 2 ) being tightly fixed to the plate around the dish ( 345 ).
