Definitions
- the present invention relates to a fluid dispenser device.
- the present invention relates to a dispensing device specially adapted for dispensing fluid product having a viscous consistency.
- Preferred but not exclusive fields of application of the present invention include cosmetics, perfumery and pharmacy.
- Such systems generally implement a reservoir whose useful volume, that is to say the volume exclusively dedicated to contain the fluid to be dispensed, varies with each distribution of fluid product.
- a system may for example comprise a reservoir inside which a follower piston slides in sealed friction contact.
- the follower piston is comparable to a wall defining the bottom of the reservoir, which moves in the direction of a decrease in the effective volume of the reservoir after each actuation of the dispensing means.
- this solicitation generates a pressurization of the incompressible fluid product contained in the reservoir.
- Such a pressurization can then cause an initial displacement of the follower piston in the direction of an increase in the useful volume of the reservoir, and have the consequence of causing a defective release of the fluid product contained in the reservoir through the orifice of distribution.
- non-return means for the follower piston.
- Such non-return means are intended to prevent any displacement of the follower piston in the direction of an increase in the useful volume of the reservoir.
- These non-return means are heretofore made of a rigid part made of a hard plastic material or preferably of metal and are associated with the follower piston.
- This rigid piece of generally inverted cup shape, has on its circumference notches generally formed by being spaced equi-circumferentially. These notches thus define between them a plurality of legs with a certain flexibility.
- this rigid piece must have a configuration and a precise size to fit well inside the tank and not to hinder the movement of the follower piston.
- the attachment of such a rigid part to the follower piston requires an additional step in the manufacture and assembly of the dispensing device.
- the addition of such a part to the device necessarily generates additional cost, and therefore a higher cost.
- the present invention aims to overcome the disadvantages of the prior art mentioned above.
- the present invention aims to provide a dispensing device ensuring a regular and substantially reproducible distribution of fluid product with each actuation of the dispensing means.
- the object of the present invention is to provide a device for dispensing fluid product avoiding any retrograde displacement of the follower piston in the direction of increasing the useful volume of the reservoir during actuation of the dispensing means.
- the present invention also aims to provide a fluid dispenser device simple and inexpensive to manufacture.
- the subject of the present invention is therefore a device comprising a fluid product reservoir of variable working volume comprising a sealed sliding drum and a follower piston in leaktight sliding contact in said barrel, distribution means able to put the fluid product stored in the pressure tank so as to discharge a portion of the fluid through a dispensing orifice, and under vacuum so as to move the follower piston in the direction of a decrease in the useful volume of the reservoir, non-return means adapted to to prevent any substantial displacement of the follower piston in the direction of an increase in the effective volume of the reservoir, in which the non-return means comprise at least one chamber of variable volume which fills with fluid from the reservoir in the vacuum phase .
- the volume of said chamber increases with the displacement of the follower piston in the direction of a decrease in the useful volume of the reservoir.
- said chamber comprises a mobile wall displaceable in the vacuum phase.
- said reservoir communicates with said chamber through a passage provided with a unidirectional device capable of selectively allowing a filling of the chamber and prevent emptying of the chamber.
- said unidirectional device is a non-return valve.
- said unidirectional device may be formed by at least one through hole having a reduced section relative to that of the dispensing orifice.
- said passage is formed on the movable wall.
- said movable wall is integral with the follower piston.
- the device comprises a fixed chimney, said follower piston comprising a sleeve mounted in leaktight sliding contact in said chimney, the movable wall being integral with the sleeve and defining, with the chimney, the non-return chamber.
- said chimney and said sliding barrel both have a cylindrical configuration, said chimney occupying a substantially central position relative to said barrel so that said chimney and said barrel are concentric, and preferably monobloc.
- said reservoir occupies an intermediate axial position between the dispensing orifice and the chamber of variable volume, the direction of flow of the fluid through said passage in said variable volume chamber being opposite to the direction of expulsion of the fluid to through the dispensing orifice.
- said dispensing means comprise an elastically deformable membrane and a pusher on which one can manually press to deform said membrane.
- said dispensing orifice is selectively closed by an outlet valve.
- the follower piston moves in the shaft in an axial direction X, the volume increase of the chamber C being in the axial direction X.
- the follower piston bears, in the pressure phase, on the chamber C filled with fluid product.
- One of the principles of the chamber lies in the fact that it acts in the manner of a unidirectional hydraulic cylinder that can only lengthen, and never retract.
- the chamber creates a column of fluid product, by definition incompressible, on which the follower piston is supported when the fluid stored in the tank is pressurized.
- An advantage of the present invention is to use a very small portion of the fluid product stored in the tank to create this column of fluid product. The anti-return function is thus provided without the need to add an additional piece, as is the case in the prior art.
- FIG. 1 is a schematic sectional view of a fluid dispenser device according to a first embodiment of the present invention
- FIGS. 2b, 2b and 2c show the operation of the device illustrated in FIG.
- FIG. 3 is a schematic sectional view of a fluid dispenser device according to a second embodiment of the present invention.
- FIG. 4 is a schematic sectional view of a fluid dispenser device according to a third embodiment of the present invention.
- the device according to the present invention comprises a body 1, a follower piston 2 mounted inside the body, distribution means 3 secured to the body by means of a fastener 4, and an actuating member 5 adapted to be manually pressed to actuate said distribution means.
- a follower piston 2 mounted inside the body
- distribution means 3 secured to the body by means of a fastener 4
- actuating member 5 adapted to be manually pressed to actuate said distribution means.
- the body 1 comprises a side wall 10 comprising an open upper end and a lower end closed by a bottom wall 11.
- the side and bottom walls each have an inner surface 100 and 110 respectively defining together the overall potential volume of said body.
- the body may advantageously have a general shape of pot or bucket and in particular the inner surface 100 advantageously has a perfectly cylindrical configuration. As will be seen later in this description, such a cylindrical configuration of this inner surface is particularly useful in the present invention since this surface actually forms a sliding shaft for the follower piston 2.
- the bottom wall includes a vent port 13 and a chimney 12.
- the vent port 13 is a through hole formed through the bottom wall communicating the interior of the body with the outside atmospheric air.
- the chimney projects upwardly from said bottom wall so that the chimney has a lower end closed by said bottom wall and an open upper end defined by an upper edge 120.
- This chimney can therefore be assimilated to a one-eyed socket.
- This chimney can be, as in the illustrated embodiments, made integral with said body (and in particular with said bottom wall) or be an insert adapted to be fixedly held in said body (and in particular on said wall of bottom), for example by snapping, gluing, welding, screwing, etc.
- said stack 12 has a cylindrical configuration and occupies a substantially central position relative to said inner surface 100 of the side wall of the body so that this stack and this inner surface are concentric.
- the follower piston 2 comprises a substantially radial plate 20 provided outside the sliding lips 21 and in the center of a sleeve 22. More exactly, the sliding lips 21 extend circumferentially outside the plate
- the sleeve 22 projects downwards from the radial plate 20.
- This sleeve 22 internally forms a duct which, as can be seen in FIG. 1, has a free lower end 220 which serves a dual purpose. This end externally defines a sealing lip intended to slide in a sealed manner in the chimney 12.
- This free end defines internally a valve seat adapted to cooperate with a non-return valve 24.
- This valve comprises a foot 240 slidably mounted in a ring 23 integral with the sleeve 22 and a disc 241 adapted to come into selective sealing abutment on the seat formed by the free end 220.
- the function of this valve will be further explained in the following description.
- the free end 220 and the disc 241 together define a wall 25 which is integral with the sleeve 22 but movable relative to the chimney 12, since the sleeve will slide in the chimney.
- the follower piston 2 is inserted inside the body 1 through its open upper end.
- the sliding lips 21 then establish a tight sliding contact in the barrel 100 of the side wall 10 of the body.
- the sleeve 22 is received within the chimney 12 and establishes with said chimney a sliding contact sealing.
- This sealing contact results from the cooperation of the sealing lip of the sleeve 22 with said chimney 12.
- the chimney may form a sealing lip in leaktight sliding around the sleeve.
- such a sealing lip may extend radially outwardly from the free end 220 of the sleeve and / or may extend radially inwardly from the upper edge 120 of the chimney.
- the inner surface 110 of the bottom wall of the body, the chimney 12 and the wall 25 together define a fluid chamber C of variable volume.
- this room C can be completely empty.
- this room 120 will increase in volume by displacement of the wall 25, which is therefore a movable wall of the chamber.
- the displacement of the wall will be generated by the displacement of the follower piston in the direction of a decrease in the useful volume of the reservoir, as will be seen below.
- the dispensing means 3 comprise a fluid product distribution channel 31 and an elastically deformable membrane 30 connected to each other by an external recess 32.
- the membrane 30 flares outwardly from this recess 32 This membrane then has a general shape of dome.
- the dispensing means may comprise a ring 33, for example secured to the distribution channel 31, forming a support member for an outlet valve 7.
- the outlet valve 7 may be of similar configuration to the nonreturn valve 2 (as shown in Figure 1) or different.
- the valve 7 rests tightly on a valve seat 34 which is here formed by the upper edge of the channel 31. In the absence of pressure or in the vacuum phase, the valve rests on its seat, while in phase of overpressure or distribution, the valve is detached from its seat thereby forming a dispensing orifice 37, which is here annular.
- the embodiment of the distribution means comparable here to a pumping system is not limiting for the implementation of the present invention. Indeed, any distribution means capable of generating a pressurization of the fluid contained in the reservoir can be used.
- the distribution means 3 are associated with the body by means of a fixing member 4.
- This fixing member comprises a fixing ring 40 and a cup 41.
- the elastically deformable membrane 30 is connected firmly to the cup 41 while the fixing ring 40 is firmly fitted on the open upper end of the body 1.
- the fixing ring may comprise a radial flange 400 adapted to abut on the upper extremity of the body.
- this fastener is only an exemplary embodiment which is thus absolutely not limiting to the implementation of of the present invention.
- the fastener could be a member to be screwed, snap or crimp on the upper end of the body.
- a reservoir of fluid product R is defined by the follower piston 2, it was 100, the cup 41 and the membrane 30.
- This reservoir is preferably entirely filled with fluid, as can be seen in FIG.
- reservoir R is of variable capacity by deformation of the membrane 30 and displacement of the follower piston 2. It communicates with the dispensing orifice 37 through the sleeve 22 of the follower piston and the channel 31.
- the actuating member or pusher 5 comprises a digital bearing surface 50 from which extend downwardly a peripheral skirt 51 and a force transmission member 52.
- the actuating member 5 is secured to the distribution means 3 by positioning the force transmission member 52 in tight engagement around the distribution channel 30. In the final mounting position, the force transmission member 52 bears against the external recess 32 of the distribution means .
- the peripheral skirt is placed inside the fixing ring 40. A pressure exerted on the surface 50 of the pusher then has the effect of axially displacing the pusher along the axis X, which causes a deformation of the membrane 30.
- the fixing ring 40 can then play a guiding role of the peripheral skirt over the entire operating stroke of the pusher.
- Such an embodiment of actuator is of course not limiting for the implementation of the present invention.
- a cover 6 can be mounted on the fluid dispenser device. In the mounting position, this cover can be placed in tight engagement around the fixing ring 40. The axial depression of the cover 6 can be limited by the radial projection 400 of the fixing member.
- the cover 6 may comprise a protrusion 60 that can bear against the outlet valve 7 so as to press said valve against the upper end of the dispensing channel 50 and thus prevent any accidental dispensing of the fluid product contained in the inside the useful volume of the tank.
- the force transmitting member 52 then urges the membrane 30 which is then deformed and thus pressurizes the incompressible fluid product contained within the useful volume of the reservoir. This pressurization then generates a distribution of fluid product through the dispensing orifice 37 formed between the outlet valve 7 and the distribution channel 31.
- the non-return valve 24 of the sleeve 22 closes thus blocking any communication between the tank R and the chamber C.
- the closing of the valve 24 is controlled by the rise in pressure in the chamber C which is much faster and more important than in the tank R. This results from the important difference between the diameter of the tank and that of the chamber.
- the disk 241 of the valve 24 is then pressed onto its seat formed by the free end 220 of the sleeve.
- This depression has the effect of moving the follower piston upwards in the direction of a decrease in the useful volume of the reservoir.
- the sliding lips 21 and the sleeve 22 move in sliding contact respectively in the barrel 10 and in the chimney 12.
- the displacement of the sleeve in the chimney has the effect of moving the movable wall 25 which incorporates the non-return valve 24.
- the displacement of the wall 25 is accompanied by an opening of the valve 24, because the vacuum in the chamber C increases faster than in the tank R. This is again due to the significant difference between the diameter of the tank and that of the chamber
- the displacement of the wall 25 and the concomitant opening of the valve 24 have the effect of penetrating fluid from the tank R into the chamber C. This has the effect of increasing the useful volume of the chamber C by increasing the axial height of the column of fluid that will serve as support for the follower piston during the next overpressure phase.
- the elastically deformable membrane 30 has returned to its original configuration.
- the fluid dispensing device is thus returned to its rest position and the dispensing means 3 are again operable.
- the chamber C contains a volume of fluid greater than the volume of fluid present before actuation of said dispensing means.
- each actuation of the distribution means causes a successive increase in the volume of the chamber C.
- the volume of said chamber will increase sequentially with each movement of the follower piston in the direction of a decrease in the useful volume of the reservoir.
- the follower piston can rely on a column of incompressible fluid always higher fed by the reservoir R in the vacuum phase.
- the chamber C thus repeatedly ensures a non-return function of the follower piston during the overpressure phases.
- the fluid required to fill the chamber C is minimal compared to the volume of the reservoir R.
- the proportion is 1/40.
- the loss of fluid product is therefore about 2.5%, which remains very low.
- the nonreturn valve 24 constitutes an advantageous embodiment for a unidirectional device capable of selectively and momentarily forming a filling passage of the chamber C from the reservoir R.
- such a device ensures a filling of the chamber only in the vacuum phase of the reservoir and prevents the emptying of this chamber in the pressurized phase of the fluid contained in The reservoir.
- check valves such as a ball valve or a flexible diaphragm valve could also be used.
- FIG. 3 shows other embodiments of unidirectional devices that can be implemented in a fluid dispenser device according to the present invention.
- the unidirectional device is a valve comprising a transverse wall 221 integral in displacement of the sleeve 22. This wall is traversed by an orifice that can be selectively closed by means of a rigid or flexible tongue 222.
- the actuation of the means dispensing 3 puts the fluid contained in the tank under pressure.
- the tongue 222 is then plate against the wall 221 and prohibits any fluid product passage from the reservoir to the chamber C.
- the follower piston is displaced in the direction of a decrease in the useful volume of the reservoir and the tongue 22 is detached from the wall 221. This displacement of the tongue forms a passage between the useful volume of the reservoir and the chamber 120 thus allowing the filling of the chamber 120.
- the unidirectional device comprises a transverse wall 223 integral in displacement of the sleeve 22.
- This wall comprises one or more through-holes 224 each having a reduced section relative to that of the dispensing orifice.
- the actuation of the dispensing means places the fluid product contained in the reservoir under pressure.
- the size of the through holes 224 does not allow the fluid product contained in the useful volume of the tank to gain the chamber C because the fluid pressure prevailing in the chamber C is then much greater than the fluid pressure prevailing in the working volume of the chamber. tank.
- the fluid product contained in the useful volume of the reservoir can pass through these holes of passage 224.
- the chamber C is then filled with fluid from the reservoir.
- the follower piston is supported on a chamber comprising a movable wall 25 which is here integral with the follower piston. Moving the follower piston increases the volume of the chamber through a unidirectional flow device with fluid from the reservoir.
- the chamber is here arranged axially opposite to the dispensing orifice, but other configurations may be envisaged.
