Definitions

  • valve may move slightly with respect to its central axis, which may cause leaks at the junction between the seals and said valve.
  • This problem is particularly troublesome when the valve is a metering valve, that is to say a valve having a metering chamber defining a precise dose of product dispensed with each actuation of the valve.
  • imprecision or non-reproducibility of the dose can be harmful for the user.
  • Another problem which arises in particular in the metering valves concerns the precision and reproducibility of the metering even in the case of storage between two actuations.
  • the present invention also relates to a fluid dispenser device comprising a valve as described above.
  • the hollow sleeve 15 forming the guide element can be blind, as shown in FIG. figure 1 .
  • Another variant, represented on the figures 2 and 5 shows a hollow sleeve 15 passing through, the valve possibly being able to project out of the valve body 10, inside the tank (not shown), when the valve 20 is depressed in dispensing position.
  • the valve can not deviate during its displacement of this axis X because of the guide element 15 which axially guides the displacement of the guided portion 29 of the valve, and therefore of the entire valve. This avoids any risk of shift of the valve during actuation, and therefore any risk of leakage especially at the upper seal of the valve.
  • the valve 20 comprises an upper part 21, which incorporates the dispensing orifice 25, and a lower part 22 which incorporates the guided part 29. These upper and lower parts 21, 22 are assembled one in the other, preferably sealingly, to at least partially define the filling channel 26.
  • the lower part 22 of the valve 20 comprises a blind hole 23 which comprises two lateral through-holes 27, 28, one of which opens into the metering chamber 30 in the rest position of the valve 20, and the other opens at the outside of this metering chamber 30 in a portion connected to the reservoir.
  • At least one of said lateral orifices 27, 28, preferably both, is made at least partially conical, preferably completely conical, as shown in FIGS. figure 1 and 2 , narrowing towards the interior of the central channel 23.
  • the minimum diameter of the orifices (s) conical (s) 27, 28 is about 0.3 millimeter. With such a diameter, it is almost impossible for the product contained in the metering chamber 30 to flow back through the filling channel 26, the diameter being too small to allow a passage of the product by simple gravity.
  • the conical shape of the holes makes it possible to achieve the minimum diameter of these with a very small value of the order of 0.3 millimeters.
  • cylindrical pins for molding cylindrical holes of such a size would be too fragile, so that it would be very difficult and expensive to make cylindrical through holes of size about 0.3 millimeter in diameter.
  • tapered holes narrowing inwardly of the channel 23 the desired result is obtained, namely a retention of the dose in the metering chamber 30 while allowing a molding and a simple and inexpensive embodiment of these holes by means of very strong conical pins, of which only the end has a reduced dimension of the order of 0.3 millimeters.
