Definitions
- the present invention relates to a filling head of a fluid dispenser device comprising a valve, in particular a metering valve.
- metering valves in which each time the valve is actuated, a precise dose of fluid product is dispensed, are well known in the state of the art, and are generally assembled on a reservoir containing the fluid product and a propellant gas used to carry out the expulsion of the dose.
- the filling of the reservoir of a fluid product dispensing device comprising a valve, in particular a metering valve, is generally done by means of a filling device which sends a pressurized flow of fluid product through the valve of the valve.
- a filling device which sends a pressurized flow of fluid product through the valve of the valve.
- the valve valve is inserted into a filling head which actuates the valve by moving the valve to its dispensing position and which then injects the fluid product through the outlet port of the valve.
- the fluid passes through the valve and enters the metering chamber and thence into the reservoir by deforming the chamber seal.
- the filling pressure is between 5 and 10 bars, which is sufficient to deform the chamber seal, which typically deforms from a pressure of 2 to 3 bars.
- a disadvantage of filling heads of this type relates to the variability of the position of the valve during filling. Indeed, the fully actuated position of the valve in a metering valve, also called bottom dead center, can be defined by the valve spring in contiguous coils, with a high potential variability. While this does not pose any difficulties when using the valve to dispense the doses of fluid product, since the dose dispensing occurs before the valve reaches its end position, this indetermination of the position of there valve can cause problems during the filling phase. This is further amplified when the seal between the valve and the filling head is made on the upper axial edge of the valve, because the crushing of the seal at this point can also contribute to a variability of the final position of the valve at the time of filling.
- filling heads Another drawback of filling heads is linked to the stress exerted by the filling head on the valve body, which can generate malfunctions of the valve, for example in the event of deformation of the valve body.
- the object of the present invention is to provide a filling head for a fluid dispenser device comprising a valve which does not reproduce the aforementioned drawbacks.
- the object of the present invention is thus to provide such a filling head which improves the reliability of filling.
- the present invention also aims to provide such a filling head which eliminates the indeterminacy and variability of the filling position.
- the present invention also aims to provide such a filling head which limits the stresses on the valve body during filling.
- the present invention also aims to provide such a filling head which is simple and inexpensive to manufacture and assemble, and which operates reliably.
- the present invention therefore relates to a filling head of a fluid dispenser device comprising a valve mounted on a reservoir by means of a fixing element, said valve comprising a valve provided with a sliding axial outlet orifice in a valve body, said filling head comprising:
- control member control mounted to slide axially in said body between a rest position and a filling position, said control member control comprising a filling channel through which, in the filling position, the pressurized fluid product is supplied to said valve to fill said reservoir, said filling channel comprising an outlet opening into said reception space,
- a receiving plate fixed to said body and comprising a housing for receiving said valve, such that in the filling position, the axial outlet orifice of the said valve opens into the said receiving space, in which, in the filling position , said reception space is sealed, comprising a first seal between said control member and said body, a second seal between said body and said reception plate, and a third seal between said control plate housing and said valve, said third seal cooperating with an outer side wall of said valve, and
- valve ejection means for ejecting said valve from said housing after filling, said ejection means comprising:
- each ejector arranged axially movable in said body between an ejection position and a filling position, each ejector being arranged between said ejector cylinder and said support plate, each ejector comprising an enlarged head and an axially extending rod downward from said enlarged head, said rod passing through said body and said receiving plate to protrude into said housing in the ejection position, and
- said first seal is a dynamic seal formed by an O-ring or quadrilobe seal assembled in a groove or throat of said control member.
- said second seal is a static seal formed by an O-ring or quadrilobe seal wedged between said body and said receiving plate.
- said third seal is a dynamic seal formed by an O-ring or quadrilobe seal placed in a suitable recess of said receiving plate.
- said filling head forms only two contact zones with said valve, the first contact zone being produced between said control member and said valve and the second contact zone being produced between said support plate or an element connected to said support plate and a radially outer part of said fixing element.
- said reception space is formed in a hollow cylindrical sleeve of the body in which said control member slides axially in a sealed manner between its rest and filling positions.
- the present invention also relates to an assembly formed of a filling head as described above and of a fluid dispenser device comprising a valve mounted on a reservoir by means of a fixing element.
- said valve comprises a valve provided with an axial outlet orifice sliding in a valve body, in which, in the filling position, said valve is arranged in said receiving space of said body and said fixing element is arranged in said housing of said receiving plate.
- Figure 1 is a schematic cross-sectional view of a metering valve according to an advantageous embodiment, in the rest position of the valve, in the upright filling and storage position of the valve,
- Figure 2 is an exploded schematic view of a filling head according to an advantageous embodiment
- Figure 3 is a cross-sectional view of the filling head of Figure 2, at the start of the filling cycle before insertion of the valve,
- Figure 4 is a view similar to that of Figure 3, after insertion of the valve and before filling,
- Figure 5 is a view similar to that of Figure 4, being filled
- Figure 6 is a view similar to that of Figure 5, after filling, and
- Figure 7 is a view similar to that of Figure 6, after ejection of the valve.
- top, bottom, lower, lower and lower refer to the upright position shown in Figures 3 to 7, and the terms “axial” and “ radial” refer to the central longitudinal axis X of the valve.
- Figure 1 shows a valve 100 in the upright filling position, that is to say the position in which the valve is arranged above the reservoir 200, of which only the neck 201 is shown schematically.
- the valve 100 shown in this example is a metering valve.
- the metering valve 100 shown in Figure 1 comprises a valve body 110 extending along a central longitudinal axis X. Inside said valve body 110, a valve 120 slides between a rest position, which is that shown in Figure 1, and a dispensing position, in which the valve 120 is pressed axially downwards inside the valve body 110.
- This valve 100 is assembled on a reservoir 200 adapted to contain fluid product and a propellant gas by means of a fixing element 130, which can be a crimp, screw or snap cap, with the interposition of a neck 140.
- a ring 150 can be assembled around the valve body 110, in particular to reduce the dead volume in the inverted position of use and/or to limit the contact of the fluid product with the neck seal 140.
- the tank 200 is intended to contain the fluid product and the propellant gas, in particular a formulation consisting of one or more active principle(s) in suspension and/or in solution in a liquefied propellant gas, as well as optionally excipients.
- the propellant gas advantageously comprises an HFA gas, for example HFA 134a and/or HFA 227.
- the propellant gas comprises HFA-152a.
- other non-harmful gases such as HFO1234ze, can be used.
- valve 120 is biased towards its rest position by a spring 160, which is arranged in the valve body 110 and which cooperates on the one hand with this valve body 110, and on the other hand with the valve 120, preferably with a radial flange 129 of valve 120.
- a metering chamber 170 is defined within valve body 110, said valve 120 sliding within said metering chamber 170 to allow the contents thereof to be dispensed. ci when the valve is actuated.
- the valve 120 is made in a single one-piece part, including an upper part (also called the valve top) and a lower part (also called the valve bottom).
- the upper part comprises a central axial channel 122 provided with an axial outlet orifice 121 and a radial inlet channel 123 which is arranged in the metering chamber 170 when the valve 120 is in the dispensing position.
- the lower part comprises an axial internal channel 125 provided with a radial outlet channel 124.
- the lower part also comprises the collar 129 on its external surface.
- the internal axial channel 125 connects the metering chamber 170 to the reservoir 200, to fill said metering chamber 170 before each use. This filling is done when the device is in the inverted position of use, with the valve 100 arranged below the reservoir 200.
- valve 120 when the valve 120 is in the rest position, the metering chamber 170 is connected to the reservoir via the internal axial channel 125 of the valve 120. In this rest position, the metering chamber 170 therefore remains connected to the reservoir and can be emptied by gravity in the straight position of FIG.
- the valve represented in FIG. 1 is therefore a valve of the non-priming type.
- the invention is however also applicable to other types of valves, in particular valves of the retention type.
- the valve body 110 comprises a cylindrical part 115 in which the spring 160 is arranged and in which the collar 129 slides between the rest and dispensing positions.
- this cylindrical part 115 is the lower part of the valve body 110.
- This cylindrical part 115 has one or more longitudinal openings 111, such as slots, extending laterally in said cylindrical part 115 of the body. valve, over part of the axial height of the valve body in the direction of the longitudinal central axis. These openings 111 allow the metering chamber 170 to be filled before each actuation, when in the inverted position of use (with the valve placed under the reservoir), the valve 120 is in its rest position.
- the metering chamber 170 is defined between two annular seals, a top seal or valve seal 171 and a bottom seal or chamber seal 172, in a well-known manner. This metering chamber 170 is filled before each actuation with a dose of fluid product from the reservoir, when the user returns the device to the inverted position.
- the volume of the metering chamber 170 is defined by means of a chamber insert 175, of substantially cylindrical shape, with a cylindrical wall having a greater or lesser radial thickness depending on the desired volume. This volume can advantageously vary between 25 and 75 pl.
- the chamber seal 172 advantageously comprises a radial sealing lip 173 to improve the dynamic seal with the valve 120 during its movement during actuation of the valve.
- This deformable lip 173 extends radially inwards and axially downwards. This implementation makes it possible to guarantee a perfect seal when the valve 120 moves in one direction then in the other direction during an actuation.
- this radial sealing lip allows easy filling of the reservoir through the valve without the risk of damaging the bottom seal 172, as will be described below.
- Figures 2 to 7 describe a filling head of a filling device according to an advantageous embodiment.
- This filling head comprises the following elements: a control member 10, an upper plate 20, a support ring 30, an ejector cylinder 40, a body 50, at least one ejector 60 and a receiving plate 70.
- First fixing means 1 are provided for fixing the control member 10 to the motor (not shown) of the filling device, second fixing means 2 are provided for fixing the upper plate 20 to the body 50, and third means for fixing 3 are provided for fixing the receiving plate 70 to the body 50.
- These various fixing means can be formed respectively by one or more screws, or the like.
- a first seal 4 is provided on the control member 10, to cooperate with a part of the body 50 when the control member 10 moves relative to the body 50.
- This first seal 4 is a dynamic seal, and may be formed by an O-ring or quadrilobe seal assembled in an appropriate groove 13 of the control member 10.
- a second seal 5 is provided between the body 50 and the receiving plate 70.
- This second seal 5 is a seal static, and can be formed by an O-ring or four-lobe seal wedged between the body 50 and the receiving plate 70.
- a third seal 6 is provided between the receiving plate 70 and the valve valve 120.
- This third seal 6 is a seal dynamic, and can be formed by an O-ring or quatrefoil disposed in a suitable recess of the receiving plate 70 to cooperate with an outer side wall of the valve 120.
- a first spring 7 is provided between the support ring 30, fixed to the control member 10, and the body 50.
- a second spring 8 can optionally be provided between the upper plate 20 and the ejector cylinder 40.
- a centering pin 9 may be provided between the body 50 and the receiving plate 70.
- the assembly of the filling head of FIG. 2 can be carried out as follows.
- the receiving plate 70 is fixed to the body 50 by the third fixing means 3 after positioning the centering pin 9 and the second and third seals 5 and 6.
- the filling head comprises means for ejecting the valve after filling.
- Each ejector 60 is advantageously inserted from the top into the body 50.
- Each ejector 60 comprises an enlarged head 61 and a rod 62 extending axially downwards from said head.
- the rod 62 passes through the body 50 and the receiving plate 70 through appropriate openings, while the head is retained axially by a shoulder 72 of the receiving plate 70. In the rest position, each ejector is therefore positioned with the head widened 62 in abutment against the respective shoulder 72 and the rod 62 extending in a housing 71 of the receiving plate 70.
- the ejector cylinder 40 is then inserted into the body 50 from above, with the bottom wall of said ejector cylinder 40 cooperating with the enlarged head of each ejector 60.
- the first and second springs 7 and 8 are inserted into the body 50 from above, with the first spring 7 which bears directly on an internal part of the body 50 and the second spring 8 which bears on the bottom wall of the ejector cylinder 40.
- the two springs 7, 8 are concentric, with the first spring 7 which is radially inside the second resort 8.
- the second spring 8 is optional.
- the control member 10 comprises an axial rod part 11 which comprises a fixing profile 12, for example a snap-in profile or a screwing profile, intended to receive the support ring 30 and a groove or groove 13 intended to receive the first seal 4.
- the upper plate 20 has a hole in its center and is arranged around the axial rod part 11 of the control member.
- the support ring 30 is inserted from below in the lower part of the upper plate 20 to snap or screw onto the fixing profile 12 of the axial rod part 11 .
- This assembly is then fixed to the body 50 by means of the second fixing means 2, with the first spring 7 which cooperates with the support ring 30 and the second spring 8 which cooperates with the upper plate 20.
- the at least one ejector 60 and the ejector cylinder 40 are axially movable in the body 50 between an ejection position and a filling position, in which each ejector 60 is moved axially upwards in the body 50, causing the axial displacement upwards of the ejector cylinder 40 and thereby the compression of the second spring 8.
- the control member 10 comprises a filling channel 15, which extends axially in the center of the axial rod part 11, and whose lower axial end, which comprises an outlet orifice 16, opens into a reception space 55 of body 50 defined by a hollow cylindrical sleeve 54 of body 50.
- the control member 10 is therefore axially movable in the body 50 between its rest position and its filling position. During this axial displacement, the first seal 4 cooperates in a sealed manner with said hollow axial sleeve 54 to maintain said reception space 55 sealed. In addition, when the control member 10 moves towards its filling position, the first spring 7 compresses, to at the end of filling return the control member 10 to its rest position.
- This filling head is a so-called blank press head, that is to say that the pressure which it exerts on the valve is applied on the one hand to the valve 120 and on the other hand to the radially external part of the fixing element 130, that is to say the part which cooperates with the reservoir 200 via the neck seal 140.
- the filling head There are therefore no stresses exerted by the filling head on the radially internal part of the fixing element 130, that is to say the part which cooperates with the valve body 110 via the valve seal 171 .
- the seal between the head and the valve is not achieved by means of a seal arranged axially above the radially upper edge of the valve, which defines the outlet port. 121 of the valve, but on a lateral side of the valve.
- the valve top enters the receiving space 55 via an axial opening of the receiving plate 70 aligned with an axial opening of the body 50, with the third seal 6 which cooperates in a leaktight manner with the outer side wall of the valve, as shown in Figures 5 and 6.
- the at least one ejector 60 which at rest protrudes into a housing 71 formed in the receiving plate 70, is pushed upwards by the fixing element 130 of the valve, as visible in Figures 3 and 4, which also moves the ejector cylinder 40 and compresses the second spring 8.
- the filling process can begin.
- the outlet orifice 16 of the filling channel 15 forms a small projection which can penetrate slightly into the axial outlet orifice 121 of the valve 120.
- the control member 10 is moved axially downwards, which moves the valve 120 towards its filling position.
- the pressurized fluid product can then be injected through the filling channel 15 of the control member to pass through the valve 120 then to the reservoir 200.
- the sealing of the space of reception 55 is ensured by the first seal 4 between the control member 10 and the body 50, by the second seal 5 between the body 50 and the reception plate 70, and by the third seal 6 between the reception plate 70 and valve 120.
- the first spring 7 returns the control member 10 to the rest position, as illustrated in FIG. 6, and the at least one ejector 60 ejects the valve from the housing 71 of the receiving plate 70, via the ejector cylinder 40 and the second spring 8, as shown in Figure 7.
- the ejection means in this case the ejectors 60 and the associated elements, namely the ejector sleeve 40 and the second spring 8, are not mandatory for the proper functioning of the filling head.
- An advantage of using such ejection means is to guarantee a good separation between the valve and the head. Indeed, due to the seal made on a side wall of the valve 120, there is some resistance to the withdrawal of the valve from the housing 71 of the receiving plate 70, and the use of ejectors 60 can be advantageous.
- An advantage of the filling head described above is the better control of the position of the valve in the valve during filling, which is less subject to variability thanks on the one hand to the absence of a seal arranged axially between the edge upper part of the valve 120 and the lower edge of the axial rod part 11 of the control member 10, on the other hand to the absence of contact between the filling head and the radially internal part of the fixing element 130, and also because the spring 160 of the valve is not brought to contiguous turns in the filling position.
- the only contact between the head and the fixing element is provided only on the radially outer part of the fixing element, which eliminates the variability linked to the valve seal and moreover protects the valve body, and in particular the chamber. dosing, against all constraints during filling.
