Fluid Product Dispenser

Abstract

A dispenser for dispensing fluid, such as a perfume, the dispenser comprising: a fluid receptacle ( 1 ); an actuatable dispenser member (O) that is suitable for taking and for dispensing doses of fluid; and a supply tube ( 24 ) connecting the receptacle to the dispenser member; the dispenser being characterized in that: the dispenser member includes a deformable, flexible envelope ( 6 ), the dispenser member being actuatable by deforming the envelope; and, in use, the dispenser member is movable relative to the receptacle.

1 . A dispenser for dispensing fluid, such as a perfume, the dispenser comprising:
 a fluid receptacle ( 1 );   an actuatable dispenser member (O; O′; O″) that is suitable for taking and for dispensing doses of fluid; and   a supply tube ( 24 ) connecting the receptacle to the dispenser member;   the dispenser being characterized in that:
 the dispenser member includes a deformable, flexible envelope ( 6 ;  6 ′;  6 ″), the dispenser member being actuatable by deforming the envelope; and 
 in use, the dispenser member is movable relative to the receptacle. 
   
   
   
       2 . A fluid dispenser according to  claim 1 , in which the supply tube ( 24 ) is flexible. 
   
   
       3 . A fluid dispenser according to  claim 1 , in which the dispenser member (O′; O″) is connected to the reservoir via the tube ( 24 ) only. 
   
   
       4 . A fluid dispenser according to  claim 1 , in which the envelope ( 6 ′;  6 ″) is provided with a dispenser orifice ( 71 ). 
   
   
       5 . A fluid dispenser according to  claim 1 , in which the dispenser member (O) is further provided with an expulsion tube ( 25 ) that is advantageously flexible, and that is connected to a dispenser orifice ( 71 ) that is secured to the receptacle. 
   
   
       6 . A fluid dispenser according to  claim 1 , in which the flexible envelope forms a squeezable bulb. 
   
   
       7 . A fluid dispenser according to  claim 1 , in which the flexible envelope ( 6 ″) includes an inlet valve ( 61 ), an outlet valve ( 62 ), and a dispenser orifice ( 71 ). 
   
   
       8 . A fluid dispenser according to  claim 1 , in which the dispenser member (O; O′) includes a pump ( 2 ) housed inside the envelope ( 6 ;  6 ′). 
   
   
       9 . A fluid dispenser according to  claim 8 , in which the pump ( 2 ) comprises a body ( 20 ) that defines the inlet ( 21 ), and a movable actuator rod ( 23 ) that defines the outlet, said actuator rod ( 23 ) projecting out from the body ( 20 ), the rod being connected to force transmission means ( 5 ) that are suitable for transforming the manual compression force exerted on the flexible envelope ( 6 ;  6 ′) into a movement of said rod in said body ( 20 ). 
   
   
       10 . A fluid dispenser according to  claim 9 , in which the manual compression force is exerted in a direction that is different from the travel direction of the rod, the directions advantageously being substantially perpendicular to each other. 
   
   
       11 . A fluid dispenser according to  claim 9 , in which the transmission means ( 5 ) comprise a toggle system comprising:
 a mounting frame ( 4 ) on which the body ( 20 ) of the pump is mounted in stationary manner;   a bracket ( 3 ) that is secured to the rod ( 23 ), the bracket being movable relative to the frame;   at least one toggle ( 50 ,  51 ), and advantageously two, bearing firstly against the frame, and secondly against the bracket, with deformation of the envelope causing the toggle to be actuated, thereby causing the bracket to be moved relative to the frame, and thus driving the rod into the body.   
   
   
       12 . A fluid dispenser according to  claim 11 , in which the toggle system comprises two toggles, each toggle comprising at least two levers ( 50 ,  51 ) that are movable in pivoting relative to each other about a hinge point ( 52 ).
