Definitions

  • Fluid dispensing valve and fluid dispensing device comprising such a valve
  • the present invention relates to a fluid dispenser valve.
  • the present invention relates to a so-called metering valve, in which each actuation of the valve, a precise dose of fluid is dispensed.
  • valves are well known in the state of the art, and are generally assembled on a reservoir containing the fluid and a propellant gas used to achieve the expulsion of the dose.
  • Two types of metering valves are known, namely, on the one hand, those which, after filling of the metering chamber, seal off the latter until the next operation of the valve, and on the other hand those which are not filled. than just before the actual actuation.
  • the valves of the second category allow the metering chamber to fill quickly when the user will operate the valve.
  • the metering chamber can refill, but if the valve is stored in the upright position, then this metering chamber can be emptied into the reservoir, the metering chamber being then not sealed tightly.
  • Document FR-2,860,503 describes a valve of the prior art.
  • the present invention aims to improve the metering valves of the second category, that is to say those in which the metering chamber is not sealed in a rest position of the valve.
  • the present invention is intended in particular to provide a fluid dispenser valve that is simple and inexpensive to manufacture and assemble, and reliable operation.
  • the present invention also aims to provide a fluid dispensing valve for easy and safe filling of the metering chamber before each actuation while ensuring a good operating reliability of said valve.
  • the present invention therefore relates to a fluid dispensing valve, having a valve body containing a metering chamber, and a valve sliding in said valve body between a rest position and a dispensing position, for selectively dispensing the dispensing valve.
  • content of said metering chamber, said metering chamber being, in the rest position of the valve, connected to a fluid reservoir containing the product to be dispensed via a fluid flow passage, said valve comprising a radial support flange, said fluid flow passage at said flange passing at least partially inside said valve and / or flange to allow gravity filling of the metering chamber when in position resting valve, the valve is in an inverted position with the dosing chamber disposed below the reservoir, and to allow the vida when said gravity metering chamber is in the rest position of the valve, the valve is in an upright position with the metering chamber disposed above the reservoir.
  • said valve is urged elastically towards its rest position by a spring cooperating on the one hand with the valve body and on the other hand with said radial support flange of the valve.
  • said radial flange comprises at least one axial through passage for the flow of the fluid product.
  • said radial collar comprises a peripheral wall, preferably substantially annular, and at least one, advantageously at least two, preferably at least three, traversing axial axes defined radially inside said peripheral wall.
  • said radial flange is formed in a lower portion of the valve assembly in an upper portion of the valve.
  • said flange is formed on an assembled tubular piece, in particular fitted, around said valve.
  • said flow passage being at least partially inside said valve.
  • said valve comprises a central central axial passage extending in said valve over part of its height, said axial passage being open at the lower end of the valve and at an intermediate portion thereof.
  • said axial passage is open on the lower axial end of the valve, in the upright position of the valve, and laterally at the intermediate valve portion.
  • said valve is made in two parts assembled one in the other, preferably at said intermediate portion.
  • said flow passage passes exclusively inside said valve.
  • said flow passage passes inside and outside said valve.
  • the present invention also relates to a fluid dispenser device comprising a valve as described above.
  • FIG. 1 is a diagrammatic cross-sectional view of a dispensing valve according to a first embodiment of the present invention, in the rest position
  • FIG. 2 is a detail view in perspective of the lower part of the valve of the valve of FIG. 1,
  • Fig. 3 is a view similar to that of Fig. 1, showing a second embodiment of the present
  • Fig. 4 is a view similar to Figs. 1 and 3, showing a third embodiment of the present invention. .
  • the valve shown in Figure 1 comprises a valve body 10 within which a valve 30 slides between a rest position, which is that shown in the figure, and a dispensing position in which the valve 30 is depressed.
  • This valve is generally intended to be assembled on a tank (not shown), preferably by means of a fastening element 5, which may be a crimp, screw or snap-on cap. and advantageously with the interposition of a neck seal 6.
  • a ring (not shown) can be assembled around the valve body, in particular to reduce the dead volume in the inverted position and to limit the contact of the fluid with the seal of collar.
  • valve 30 is urged towards its rest position by a spring 8, which is arranged in the valve body 10 and which cooperates on the one hand with this valve body 10, and on the other hand with a radial support flange 320 of the valve 30.
  • a dosing chamber is arranged in the valve body 10 and which cooperates on the one hand with this valve body 10, and on the other hand with a radial support flange 320 of the valve 30.
  • valve 20 is defined within the valve body 10, said valve 30 slidable within said metering chamber to permit dispensing of the contents thereof when the valve is actuated.
  • the metering chamber is preferably defined between two annular seals, a valve seal 21 and a chamber seal 22, as is well known.
  • Figure 1 shows the valve in the rest position of the valve and in the upright position, that is to say the position in which the metering chamber 20 is disposed above the reservoir (not shown).
  • the valve 30 has an outlet port 301 connected to an inlet port 302, which is disposed in the metering chamber 20 when the valve 30 is in the dispensing position.
  • the outer peripheral surface of the valve flange 320 is preferably approximately corresponding in shape to that of the valve body 10, that is to say generally cylindrical, and is advantageously arranged at a small distance from said valve body to avoid any risk of axial offset of said valve when its actuation.
  • the metering chamber 20 is permanently connected to the reservoir, since the metering chamber 20 is not sealed in this rest position of the valve 30.
  • the metering chamber When the valve is stored in the upright position, the metering chamber is empty and when the user wishes to reuse the valve, it will have to return it in the inverted position, that is to say the position in which the metering chamber 20 is disposed below the tank, so that it can fill by gravity.
  • the fluid flow passage between the metering chamber 20 and the reservoir passes, at the collar 320, at least partially inside. of the valve 30.
  • a flow passing exclusively outside the valve can be hindered or at least slowed, which can to pose problems of dosage when the user actuates the valve relatively quickly after having positioned it in inverted position.
  • Providing a fluid flow passage 35 at least partially inside the valve 30 ensures a faster flow and therefore a more reliable filling of this metering chamber 20.
  • the radial flange may comprise a peripheral wall 320 preferably substantially annular or cylindrical, and at least one through axial passage, preferably at least two, preferably at least three passages.
  • the example shown in FIG. 2 even has four through passages 35. These passages 35 are defined radially inside the peripheral wall 320, and around a central core of the valve.
  • the valve 30 is made in two parts, namely an upper part 31 (also called high valve) and a lower part 32 (also called bottom valve) looking in the right position of FIG. 1.
  • the lower part 32 is in this embodiment assembled inside the upper part 31, and the flange 320 is an integral part of this lower part 32 as clearly visible in FIG. 2.
  • FIG. 3 represents a second variant embodiment of the present invention, in which the flange 320 is part of a tubular piece 32 'which is assembled, preferably fitted, around the valve 30.
  • the valve 30 is substantially made of a single piece, and it is the tubular piece 32 'which defines both the flange 320 for effective guiding of the valve during its actuation and the passage (s) through ( s) 35 for the flow of the fluid as described with reference to the first embodiment shown in Figures 1 and 2.
  • This implementation provides better rigidity because there is no assembly of a lower part and an upper part of the valve. As schematically shown in FIG.
  • the interior of the through passage (s) 35 may comprise inclined or helical profiles to give the product, as it passes through these passages, a slightly swirling movement which will promote a good homogenization of the dose when it will enter the metering chamber 20.
  • This implementation could also be provided in the embodiment of Figures 1 and 2.
  • Figure 4 there is shown another mode embodiment of the present invention, wherein the flow passage 35 'extends, at the collar 320, at least partially within the valve 30, in particular axially and centrally.
  • the valve is again made of two parts, an upper portion 31 and a lower portion 32, the lower portion 32 being assembled within the upper portion 31.
  • the axial passage internal 35 extends inside the lower part 32 on a major part of its height, advantageously from the lower axial end which is open 352 to a lateral opening 351 disposed above the collar 320, advantageously near the interface between the lower part and the upper part .
  • This lateral opening 351 opens at least partially into the metering chamber 20 to allow its filling.
  • the flow passage 35 'therefore extends between the lower end of the valve and an intermediate portion thereof.
  • the example shown in Figure 4 involves a double flow at a time during filling and emptying of the metering chamber 20, a first part of the flow (usually the main part) passing inside the valve
  • valve 30 in the axial flow passage 35 ', and another part of the flow passing outside the valve 30 and outside the collar 320.
  • This double flow also allows to promote a homogeneous dose inside. of the dosing chamber at the time of dispensing thereof.
  • the valve 30 can co-operate externally in a sealed manner with the seal 22 of the metering chamber 20, in any position, so that the flow passage 35 'between the metering chamber and the reservoir passes exclusively Inside the valve 30.
  • the flange 320 which is solid in the example of Figure 4, could also include one or more through passages or slots for the fluid. These passages or slots could also be provided on the valve portion disposed between the flange 320 and the seal 22. This would limit the dead volume, especially in a configuration similar to that of Figure 4, but the seal 22 would cooperate with sealingly with the outside of the valve, thus favoring the filling in the inverted position.
