Definitions

  • the present invention relates to dispensing devices for fluid products.
  • the fitting wall tends to undergo shrinkage phenomena in particular facing the nozzle receiving stud, which hampers the proper fitting of this fitting wall on an actuating rod.
  • hollow pump or fluid dispensing valve In dispensing devices of this type, the fitting wall tends to undergo shrinkage phenomena in particular facing the nozzle receiving stud, which hampers the proper fitting of this fitting wall on an actuating rod.
  • the present invention is intended to overcome this disadvantage.
  • a dispensing device of the kind in question is characterized in that a recess is managed in the stud and open facing the outlet orifice of the nozzle, said fitting wall having a second thickness facing said recess, the second thickness being less than 1.1 times the first thickness.
  • the material thickness of the pusher is reduced at the level of the stud, which makes it possible to strongly limit the aforementioned withdrawal phenomena. This results in better control of the internal dimensions of the fitting wall, so a better holding of the pusher on the pump actuating rod or valve on which it is intended to be fitted.
  • the presence of the aforementioned recess improves the quality of the spray, especially when the fluid to be dispensed arrives in the vortex chamber at a relatively low pressure (for example a pressure of less than 4 bar).
  • a relatively low pressure for example a pressure of less than 4 bar.
  • there is a homogeneous distribution of droplets of sprayed fluid while with the devices of the prior art, there is an inhomogeneous distribution of droplets of sprayed fluid (generally, in the case of low fluid pressure, the droplets tend to form a hollow cone, so with a low density of droplets in the vicinity of the axis of the outlet).
  • FIG. 1 represents a dispensing device 1 for a fluid product, intended to dispense, for example, a cosmetic product or the like, in particular having a liquid or semi-liquid consistency.
  • the dispensing device 1 shown in FIG. 1 comprises a reservoir 2 containing fluid product, under pressure or not, and a dispensing mechanism 3 such as a manual spray pump (or, if appropriate, a valve if the fluid product is under pressure in the tank 2).
  • a dispensing mechanism 3 such as a manual spray pump (or, if appropriate, a valve if the fluid product is under pressure in the tank 2).
  • This dispensing mechanism 3 comprising a hollow actuating rod 4 which extends along a central axis Z and which is slidably mounted in the body 5 of the dispensing mechanism.
  • the actuating rod 4 is adapted to allow a fluid product outlet when said actuating rod 4 is pressed into the body 5.
  • the outlet of the fluid product in question can optionally be carried out at relatively low pressure, for example at a pressure below 4 bar.
  • a pusher 6 is fitted on the actuating rod 4.
  • This pusher 6 may for example be molded in one piece of thermoplastic synthetic material, in particular polyolefin (for example, polypropylene or the like).
  • This outlet nozzle 14 In the nozzle receiving housing 12 is force-fitted an outlet nozzle 14 clearly visible in FIGS. 1 and 2.
  • This outlet nozzle which may be made for example of molded plastics material, has a front wall 15 perpendicular to the housing. X axis and a substantially cylindrical side wall 16 whose outer surface is tightly fitted into the nozzle receiving housing 12.
  • the front wall 15 of the outlet nozzle is pierced with an outlet orifice 17 which may be for example centered on the axis X.
  • This outlet orifice 17 communicates with an intermediate chamber 18 hollowed out in the inner face of the front wall 15 which intermediate chamber communicates with one or more fluid inlet channels 19 themselves dug in the inner face of the front wall.
  • the intermediate chamber 18 has a substantially cylindrical shape centered on the X axis and the channels 19, which here are 3 in number, are arranged substantially tangentially with respect to the intermediate chamber 18, so as to cause a swirl of the fluid arriving through the channels 19 in the intermediate chamber 18.
  • the above described arrangement of the intermediate chamber 18 and the channels 19 is given for illustrative purposes only and could be modified without depart from the scope of the present invention.
  • the channels 19 communicate with an annular space 20 arranged between the inner surface of the side wall 16 of the nozzle and the outer surface of the pad 13 of the pusher, and this annular space 20 communicates itself, via a conduit 21 formed in the pusher, with the upper end of the well 10 in which is engaged the actuating rod 4 of the dispensing mechanism 3.
  • a recess 22 is formed in the stud 13.
  • This recess 22 may for example have a substantially cylindrical shape of revolution about the X axis, or possibly a slightly divergent shape towards the outside.
  • the recess 22 extends along the X axis between a bottom formed by a portion of the fitting wall 9 and an open end opening into the intermediate chamber 18, facing the outlet orifice 17.
  • the fitting wall 9 has, in a plane perpendicular to the axis Z and containing the axis X, a first thickness e1 outside the nozzle receiving housing 12, and a second thickness e2 at the recess 22.
  • the second thickness e2 is less than 1.1 times the first thickness e1.
  • the second thickness e2 may be less than or equal to the first thickness e1.
  • the second thickness e2 is smaller than the first thickness e1, and said thickness e2 is for example between 0.3 and 0.7 times the first thickness e1.
  • the recess 22 of the stud delimits an annular wall 23 of said stud which has a third thickness e3 (measured radially with respect to the axis X) generally less than 0.7 times the first thickness e1 and for example between 0 , 2 and 0.6 times the first thickness e1.
  • the side wall 11 represents a fourth thickness e4 which may be less than 0.8 times the first thickness e1, and for example between 0.3 and 0.7 times the first thickness e1.
  • the presence of the recess 22 in the stud makes it possible to avoid irregularities in the internal shape of the branch wall 9, and thus to ensure a good fit of the pusher 6 on the actuating rod 4.
  • the aforementioned outlet orifice 17 has a first diameter d1 which is generally of the order of a few tenths of a millimeter, for example of approximately 0.3 millimeter, while the maximum diameter d2 of the recess 22 may be greater than 2 times the diameter d1, for example between 2 and 3 times the diameter d1. In the example considered here, the maximum diameter of the recess 22 can thus be, for example, of the order of 0.8 millimeters. Finally, the intermediate chamber 18 may have a diameter d3 greater than the diameter d2, for example of the order of 0.9 millimeters, in the particular case shown in the drawings.
