Definitions

  • the present invention relates to a fluid spray head.
  • Fluid dispensing heads are well known.
  • the head In order to obtain a finely sprayed distribution in the form of a spray, the head generally comprises a spray profile disposed just upstream of the spray orifice.
  • This spraying profile can be formed by an external part, called external nozzle, reported from the outside, as described in the documents U.S. 3,625,437 , EP-0 906 785 , FR-1 355 350 and EP-0 412 524 .
  • This solution has the major disadvantage of a risk of expulsion of said nozzle during use.
  • it has been proposed to achieve the spray profile by means of an insert introduced into the head from the inside thereof, said insert forming the bottom of said spray profile and limiting the dead volume.
  • the documents WO 00/54887 and FR-2,767,311 describe devices of this type.
  • the document WO 00/54887 described in figures 1-3 a spray head of the prior art according to the preamble of claim 1.
  • the characteristics of the spray in particular, the size distribution of the droplets and the reproducibility of these characteristics are largely dependent on the shape of said spray pattern. It turns out that in most fluid dispensing devices, including drug, the performance is inconsistent due to manufacturing tolerances during molding of the head. This is explained in particular by an eccentricity of the central axis of the orifice of the insert relative to the central axis of the spray chamber.
  • This eccentricity may result in an asymmetry of the spray profile, with for example access to a virtually non-radial channels clogged. As a result, the swirling of the product in the spray chamber is less, and the performance and characteristics of the spray are affected.
  • This eccentricity of the axes can be quite important and especially be very variable from one head to another. This prevents constant spray characteristics.
  • the present invention aims to provide a fluid spray head that does not reproduce the aforementioned drawbacks.
  • the object of the present invention is to provide a safe and reliable fluid spray head which has consistent and reproducible product spray performance and characteristics for all heads from the same mold.
  • the present invention also aims to provide a fluid spray head that is simple and inexpensive to manufacture and assemble.
  • the present invention therefore relates to a fluid spray head as described in claim 1.
  • Advantageous variants are described in the dependent claims.
  • the present invention also relates to a set of spray heads manufactured from the same mold cavity, said heads being made as described above.
  • the standard deviation of the eccentrations of the central axis of the insert relative to the central axis of the expulsion channel for all the spray heads from the same mold cavity is less than 0.05 mm. , advantageously less than 0.02 mm.
  • the present invention also relates to a fluid dispenser device comprising a head as described above.
  • the present invention applies to all types of fluid product spray head according to claim 1.
  • the present description will however be made with reference to an elongated head, for example a nasal dispensing head, having a spray orifice directed in the axis of the head.
  • the present invention could be applied to all types of heads and in particular the heads in which the spray is distributed transversely.
  • the fluid spray head comprises an expulsion channel 5 which is provided with a spray orifice 1 and a spray profile 10 which is disposed upstream of said spray orifice 1.
  • the profile In the bottom wall of the spray head the spraying means 10 comprises, in known manner, spray channels 11, preferably non-radial, leading into a central spraying chamber 12 arranged directly upstream of said spray orifice 1. These channels can be three in number, as shown on the figure 1 , but another configuration is possible.
  • An insert 20, preferably solid and of simple form similar to a rod, is provided in said expulsion channel 5 to limit the dead volume and form the bottom of said spray profile 10.
  • This insert 20 is introduced through the interior of the head and therefore forms an internal nozzle for which there is no risk of expulsion of the nozzle during actuation, unlike an external nozzle, reported by the outside of the head.
  • the product flowing in the expulsion channel around said insert arrives, at the front face thereof, in the non-radial channels 11 via access 15.
  • the product then enters the spraying chamber 12 by swirling before being expelled through the spray orifice 1 in the form of a spray.
  • the device of the invention is formed of only two parts, an outer part forming the head and an inner part forming the insert.
  • the present invention is characterized in that the central axis X of the insert 20 is as much as possible identical to the central axis Y of the expulsion channel 5.
  • centering means are provided for the insert 20.
  • the centering means are formed in the expulsion channel 5, close to said spray profile 10. They comprise one or more projections adapted to cooperate with the insert 20 to center it.
  • the figure 3 shows an advantageous embodiment, wherein the expulsion channel 5 comprises three flats 30 regularly distributed around the channel.
  • the projections define a registered fictitious circle whose diameter corresponds approximately to the diameter of the insert 20.
  • the flats could be replaced by different profiles, such as convex or concave projections, for example arcs of circles, or even several lugs distributed around the channel.
  • the insert 20 With the insert 20 centered, the product flows approximately evenly through the three channels 11 and a good spray is formed with optimum spray characteristics, both in terms of performance (average droplet size and size distribution droplets) than consistency (reproducibility of performance for all heads).
  • the manufacturing tolerances of the expulsion channel 5 and the insert 20 can cause a small eccentricity of the X and Y axes, but the flats 30 can limit this eccentricity.
  • this is less than 0.08 mm, preferably less than 0.03 mm.
  • spray heads from the same mold cavity have a standard deviation, with respect to the eccentricity of the central axis X the insert relative to the central axis Y the expulsion channel, less than 0.05 mm, preferably less than 0.02 mm.
  • a particularly advantageous embodiment relates to a dispensing head in which the spray chamber 12 has a diameter of about 1 mm and the spray orifice 1 has a diameter of about 0.3 mm.
  • the present invention thus makes it possible to improve the fluid dispensing heads by improving the characteristics and the performances of the spray that it delivers, as well as the constancy of these characteristics.
