  • Fluid dispensing valves especially dosing valves for dispensing pharmaceutical products in the form of aerosol sprays are well known. They generally comprise a cylindrical valve body defining a metering chamber between two seals, a high seal and a low seal, a valve sliding in a sealed manner in said metering chamber between a rest position and a dispensing position.
  • the valve body is fixed, in particular snapped or crimped into a capsule, said capsule being adapted to then be crimped onto the neck of a container containing the product to be dispensed.
  • a neck seal is interposed between the neck of the container and the capsule to seal at this level.
  • the number of consecutive parts is important, which increases the complexity of manufacture and assembly and therefore the cost of the valve.
  • the assembly of the different valve seals is relatively complicated.
  • the spring of the valve generally metallic, is embedded in the fluid, which depending on the nature of the product may have undesirable effects on said product.
  • the valve bodies generally extend inwardly of the tank on which they are assembled, thus creating a dead volume, particularly for valves used in inverted positions. This dead volume must generally be limited by adding a so-called can end ring, assembled around said valve body. This is yet another piece to manufacture and assemble.
  • the valves are generally formed of two parts assembled into one another, which further complicates the manufacture and assembly of the valve.
  • the document WO 01/66439 discloses a two-piece valve body with a seal interposed between said valve body parts.
  • the documents EP2028132 , EP-1336 822 , FR-2,850,165 , WO 01/79079 and US-3,128,924 describe other devices of the state of the art.

  • said valve body is fixed, in particular snapped, inside the fixing cap.
  • the present invention also relates to a method of manufacturing a device as described above, comprising the step of overmolding the bottom seal and the neck seal on the one-piece valve body.
  • said seals are formed from the same thermoplastic elastomer material and overmolded in the same overmolding step.
  • the method further comprises the steps of assembling the valve and the spring in the capsule and then fixing, in particular by snapping, the valve body in said capsule.
  • said top seal is pre-assembled on said valve for assembly.
  • said top seal is pre-assembled on said valve body for assembly.
  • the present invention relates in particular to a metering valve type valve for dispensing aerosol form of a medicinal fluid product, by means of a propellant gas.
  • a metering valve type valve for dispensing aerosol form of a medicinal fluid product, by means of a propellant gas.

  • a valve 20 is slidably mounted in the metering chamber 15 between a rest position, shown in FIG. figure 1 , and a dispensing position, in which the valve is pressed axially towards the inside of the valve.
  • the valve 20 is urged toward its rest position by a spring 60, which compresses when a user actuates the valve and urges the valve axially within the valve.
  • the compressed spring 60 returns the valve 20 from its dispensing position to its rest position.
  • the valve comprises a central axial channel 21 opening on one side on an axial outlet 25 and on the other side on a radial channel 22 which opens into the metering chamber 15 when the valve 20 is in the dispensing position.
  • the metering chamber 15 has a high seal 30 and a bottom seal 40 (the terms “up” and “down” referring to the upright position of the valve shown in the figure) and the valve 20 slides tightly against these two up and down joints 30, 40.

  • a neck seal 50 is interposed between the valve body 10 and the fixing member 100, which will be hereinafter called the attachment cap for the sake of simplicity of description, said neck seal 50 being intended to seal between the valve body 10 and the neck 2 of the tank 1.
  • the neck seal 50 and the bottom seal 40 of the metering chamber are overmolded onto said valve body 10.
  • these seals are formed of the same material.
  • the seal or seals are advantageously made of olefinic-based elastomeric thermoplastic material (TPE), for example PP / SBC (mixture of polypropylene and styrene block copolymer), POE (ethylene octene), PEB (ethylene butene), EVA (ethylene vinyl acetate), PP / EPDM (blend of polypropylene and ethylene propylene diene monomer).

  • POE ethylene octene
  • PEB ethylene butene
  • EVA ethylene vinyl acetate
  • PP / EPDM blend of polypropylene and ethylene propylene diene monomer
  • the valve body is made of polyolefin, which promotes the overmolding of olefinic-based TPE seals, because of the chemical affinity of these materials.
  • the molding of the polyolefin valve body and the overmolding of olefinically based TPE seals could be carried out in the same mold.
  • Other possible materials for the valve body include polybutylene terephthalate (PBT), polyoxymethylene (POM), polyamide (PA), polycarbonate (PC), polymethyl methacrylate (PMMA), polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), polypropylene (PP), polyethylene (PE), and alloys of all these materials.

  • the neck seal 50 forms a single piece with the bottom seal 40, as visible on the figure 1 .
  • the present invention thus makes it possible to eliminate constituent parts and to simplify the assembly of the valve since, after overmoulding of the seals, the unit formed by the valve body 10 and the seals 30, 40 is fixed in the crimping capsule 100. a single assembly step.
  • this attachment is made by snapping the valve body 10, in particular a radially outer snap-fitting portion 11 of the valve body 10, onto a corresponding snap-fitting shoulder 101 of the attachment cap 100.
  • This shoulder of snap-fastening 101 may for example be made by stamping.
  • the high seal 50 made of elastomer or TPE, can be made in the form of a flat gasket pre-assembled on the valve 20 or on the valve body 10.
  • axial ribs 19 are provided on the portion of the valve body receiving said top seal 50.
  • the top seal 50 could also be overmoulded on the valve body. One could thus form the three seals in one piece integrally molded on the valve body in one overmolding step.
  • the bottom seal 40 is formed of a lip for sealing. This lip extends axially downwards and radially inwards, as visible on the figure 1 and is biased radially against the valve 20. This implementation ensures a good seal.
  • the bottom seal 40 after overmolding on the valve body 10, advantageously at least partially forms the lower edge of said unit formed of the valve body and overmolded joints.
  • the closure of the tank 1 forms a surface that is approximately flat, eliminating or in any case greatly limiting the dead volume of product inside said tank. It is therefore no longer necessary to provide an end ring of the can as for conventional valves.
  • the spring 60 of the valve is completely isolated from the product contained in the reservoir or in the valve, in particular to avoid any interaction between said product and the spring, generally metallic.
  • the capsule 100 may comprise an axial extension 110 intended to accommodate said spring 60.
  • the upper end of this axial extension 110 defines the passage opening of the valve 20.
  • the shoulder 26 of the valve pushed axially upwards by the spring in the rest position, cooperates with this upper end of the axial extension 110 of the capsule to define the rest position of the valve and therefore of the valve.
  • the spring 60 cooperates on one side with a radial shoulder 26 of the valve 20.
  • said shoulder 26 has an axial length large enough to effectively guide the top of the valve during actuation.
  • the spring 60 can rely for example on said high seal 30.
  • This implementation also simplifies the assembly of the valve.
  • the valve 20 is inserted into the capsule 100, with the spring 60 which is placed around said valve 20, in contact with said shoulder 26, then the unit formed by the valve body and the seals is snapped into the capsule 100.
  • the valve is then assembled and ready to be fixed on a tank filled with the fluid to be dispensed.
  • the figure 2 represents another embodiment, in which a pellet or washer 70 is interposed between the seal 30 and the spring 60, in order to avoid potentially negative interactions between the spring and the seal, such as a deformation of said seal.
  • the pellet makes it possible to better distribute the stresses of the spring.
  • This pellet 70 also serves during filling, when the fluid product is injected at high pressure through the valve, which can cause deformation of the seal 30 due to the sudden rise in pressure in the metering chamber 15. The presence of a pellet 70 prevents such deformation.
  • the figure 3 shows another embodiment, in which the valve comprises, between the shoulder 26 and the seal 30, ribs or grooves 27 which, in the actuating position, and thus also in the filling position, are supported by their lower radial front surfaces 28 against the seal 30, in particular to prevent deformation during filling.
  • the valve 20 is made in one piece, and the metering chamber 15 is isolated from the tank by the bottom seal 40, both in the rest position and in the dispensing position. Only when the valve 20 moves between its rest and distribution positions, in a so-called filling position, the metering chamber 15 is connected to the reservoir, to allow its filling.
  • the valve 20 comprises in this respect at least one filling passage 29 which connects the metering chamber 15 to said fluid reservoir, in the filling position of the valve, this filling position being situated between the dispensing position and the position rest. More particularly, the metering chamber 15 is advantageously sealingly closed in the rest position of the valve 20, so that the bottom seal 40 seals the filling passage 29 when the valve 20 is in the rest position.
  • the bottom seal 40 thus cooperates with the valve 20 to seal the filling passage 29 both in the rest position and in the dispensing position of the valve.
  • the filling passage 29 is advantageously made by means of one or more lateral channel (s) formed in the lateral wall of the valve 20.
  • the filling is dependent in particular on the depth and the height of the this filling passage 29.
  • the valve 20 after expulsion of a dose, automatically returns to its rest position under the effect of the spring 60.
  • the bottom seal 40 no longer cooperates sealingly with the valve 20, but is at the side channel (s) (s) formed (s) in said valve 20.
  • the filling will be done more or less quickly, and the amount of the dose to be transferred into the metering chamber 15 determines the dimensions of the passage (s) side (s) 29.
  • the depression created in the metering chamber 15 after the expulsion of the previous dose may be Advance the filling of a new dose when the valve 20 passes through its filling position when moving back to its rest position. At the next actuation, the valve 20 will again pass through its filling position before reaching its dispensing position, so that if the dose was to be incomplete in the metering chamber 15, it would be completed during this actuation . It is obviously preferable to make the channel (s) side (s) (such) so that the filling of the metering chamber 15 is complete and complete, and that ensures a perfect reproducibility of the dose.
  • the figure 4 represents another embodiment outside the scope of the invention, wherein the bottom seal does not isolate the metering chamber 15 in the rest position.
  • the filling passage 29 can be replaced by one or more grooves 19 which allow rapid filling of the metering chamber 15 when the valve is returned to the inverted position when filling the chamber by pressure differential , and a slow emptying when the valve is in the right position of rest of the figure 4 Iso-pressure between the can and the chamber.
