Definitions

• Fluid product distribution valve and fluid product distributor comprising such a valve
• the present invention relates to a fluid dispenser valve, as well as a fluid dispenser comprising such a valve. More particularly, the present invention relates to a valve which simplifies the filling of the dispenser on which the valve is assembled.
• Fluid dispensing valves are well known. They generally include a valve body in which a valve slides between a rest position and a dispensing position, the valve in the dispensing position connecting the reservoir (in the case of a continuous valve) or a metering chamber (in the case of a metering valve) with the outside. The fluid is distributed through the valve by means of a propellant gas.
• the object of the present invention is to provide a valve for dispensing a fluid product which does not have the abovementioned drawbacks.
• the object of the present invention is in particular to provide a valve for dispensing a fluid product which improves filling while avoiding trauma to the functional seals of the valve during filling.
• the present invention also aims to provide a fluid dispensing valve which simplifies the filling of the dispenser on which the valve is assembled.
• the present invention aims in particular to provide such a valve which is simple and inexpensive to manufacture and assemble.
• the present invention also aims to provide a metering valve for dispensing a fluid product as described above, which guarantees precision and total reproducibility of the dosage, in particular avoiding any loss of doses between two actuations, during periods of valve rest.
• the present invention therefore also aims to provide such a valve which is reliable to use, both during the filling phase, and during the use phase of the valve during the distribution of the product.
• the present invention therefore relates to a dispensing valve for a dispenser for fluid products, comprising a valve body and a valve sliding in said valve body between a rest position and a dispensing position, said valve comprising a movable filling part.
• said filling part is fixed to said valve by snap-fastening.
• said valve comprises a through central channel, comprising a conical channel part, said filling part comprising a conical head cooperating in the position of use with said conical channel part of said valve in order to close it sealingly.
• said filling part includes a seal to ensure a tight fixing of the filling part in the valve in the use position.
• said valve is a metering valve comprising a metering chamber.
• said metering chamber is hermetically closed in the rest position of the valve.
• valve body is made in two parts fixed to one another, in particular by snap-fastening.
• the present invention also relates to a fluid product dispenser comprising a reservoir containing the fluid product and comprising a valve as described above.
• the valve is a metering valve comprising a metering chamber, said metering chamber being isolated from the reservoir in the rest position and in the valve dispensing position.
• FIG. 1 is a schematic cross-sectional view of a dispensing valve according to an advantageous embodiment of the present invention, in the filling position
• Figure 2 is a view similar to that of Figure 1, showing the filling part of the valve in the use position, and the valve in the rest position
• FIG. 3 is a view similar to that of FIG. 2, showing the valve in the dispensing position.
• the valve comprises a valve body 1 as well as a valve 10 which slides in said valve body between a rest position (represented in FIG.
• the valve shown in the drawings is a metering valve, that is to say that it comprises a metering chamber 2 which precisely defines the dose to be dispensed on each actuation of this valve.
• the valve body 1 is made in two parts and has an upper part la which incorporates the metering chamber 2, and a lower part lb which is fixed, in particular snapped on, on said upper part la . This implementation simplifies the assembly of the valve, as will be described in more detail below.
• the valve is assembled on a reservoir (not shown) of a fluid dispenser, preferably by means of a fixing capsule 40, which can be of any type, and in particular snap-on, screwable or crimpable.
• a valve seal 5 and a neck seal 6 are generally interposed between said fixing capsule 40 and respectively the valve body 1 and the neck of the reservoir.
• a ring 7 known as the end of a canister ring, can be assembled on the valve body 1, outside of the latter, in order on the one hand to limit the contact surface of the neck seal 6 with the product. contained in the tank, and on the other hand fill the dead volume and ensure maximum distribution of the product contained in the tank.
• This can end ring 7 can be fixed in any way on the tank, and in particular snapped in as shown in the drawings. Of course, it could also be made in one piece with the valve body.
• the valve 10 has a central through channel 11 as well as a lateral channel 12 which opens into the metering chamber 2 when the valve is in the dispensing position, as visible in FIG. 3.
• the valve 10 is biased towards its rest position by a spring 8, preferably disposed in the bottom of the valve body, and in particular in the lower part 1b thereof as shown in the figures.
• the valve incorporates a seal 51, preferably produced in the form of an O-ring, assembled around the valve 10, and adapted to cooperate with a reduced diameter portion 3 of the valve body inside the chamber. metering 2, for hermetically closing this metering chamber when the valve reaches the dispensing position, as shown in FIG. 3.
• the valve also comprises a second seal 52, preferably also produced in the form of an annular seal or the like, and which is adapted to cooperate with the valve body for sealingly closing the metering chamber 2 in the rest position of the valve 10, as shown in FIG. 2.
• this second seal 52 is part of a support portion 50 of the valve which is directly in contact with the spring 8, and which, in the rest position of the valve 10, is biased pa r the spring 8 in contact with a part of the valve body 1, as shown in FIG. 2, so that the second seal 52 seals the metering chamber 2 tightly. Consequently, the valve shown in the drawings is a valve in which the metering chamber is hermetically closed and completely isolated in the valve rest position. This means that the content of the dosing chamber cannot vary independently of the valve storage period, and therefore there is no risk of dose reduction during this storage period.
• the filling of the dosing chamber is done after distribution of the dose, when the valve returns from its dispensing position to its rest position, a connection between the reservoir (not shown) and the metering chamber then being produced between the moment when the first seal 51 no longer cooperates with the diameter portion reduced 3 and the time when the second seal 52 does not yet cooperate with the valve body part described above.
• the structure of the valve body in two parts, with an upper part 1a and a lower part 1b fixed, in particular snapped on, on the upper part 1a allows this support element 50 to be put in place, and favors the embodiment shown, wherein the second seal 52 cooperates axially with the reduced diameter portion 3 of the valve body.
• the valve 10 has a filling portion 15 which is movable between a filling position (shown in Figure 1) and a position of use (shown in Figures 2 and 3).
• the filling position the filling part 15 does not close the central through channel 11 of the valve 10, so that the dispenser can be filled through said central channel 11 of the valve.
• This filling therefore imposes no traumatic stress on the valve seals.
• the filling part 15 is moved to its position of use in which it is fixed in leaktight manner to the valve 10 and in which it sealingly closes said through channel 11 of the valve 10.
• this sealed fixing is produced by snap-fastening the filling part 15 inside the valve 10.
• the filling part 15 comprises a conical head, preferably provided with a seal 18.
• the through channel 11 advantageously comprises a conical channel part 13 which cooperates with said conical head of the filling part
• the filling part 15 when the latter is in the position of use.
• the seal 18 obviously serves to improve this seal.
• the filling part 15 comprises snap-on lugs 19 which, in the position of use, snap into housings 17 of the valve 10 provided for this purpose.
• the filling part 15 is integral with said support element 50. After filling, the fixing, in particular the latching of the filling part 15 in the valve 10 can be obtained for example by pushing the valve 10 fully into the valve body, which causes the lugs 19 to snap into said housings 17. After this latching, the support element 50 forms a one-piece part of the valve 10, and this valve can therefore be used to dispense the product, by being moved between its rest and dispensing positions, as described above.
