Definitions

  • the present invention relates to a spraying device and to a use of this device.
  • the invention relates to a manual spray device according to claim 1.
  • the document US-A-6,145,712 describes an example of a spray device, in which the front face of the spray nozzle has a single central hole.
  • the document WO03/02436 shows a high pressure spraying device, up to 500 bar, and provides a pusher that can be moved perpendicularly to the axis of the tank to move a blocking member and release the movement of a nozzle along the axis of the tank under the action of a spring.
  • the document EP1698399 describes a spray nozzle whose front wall is curved and has holes diverging from each other.
  • the document EP613836 shows a wall provided with pores placed on a casing remote from the pusher.
  • the document WO02/01981 describes a hollow projection extending from the pusher and having holes extending transversely of the projection.
  • the document JP2002186882 shows a spray nozzle whose front wall has openings of various shapes, including holes.
  • the spray nozzles which are conventionally mounted on pumps or on spray valves, have the drawback of causing a large dispersion of the diameter of the droplets of fluid sprayed.
  • the splitting of the fluid product into fine droplets is obtained by a dynamic phenomenon that is particularly difficult to control, generally consisting of creating a vortex in the inner chamber of the nozzle and splitting the fluid product in fine droplets when it exits at very high speed through the central hole.
  • the sprayed product consists of droplets having diameters between 5 ⁇ m and 300 ⁇ m.
  • This dispersion can prove to be undesirable when it is desired to spray droplets of substantially homogeneous sizes. For example, one may wish to spray small droplets for inhalation of bronchial drug treatments, or one may wish to spray larger droplets for cosmetic or perfumery applications, so that the droplets penetrate less. possible in the bronchi of the user.
  • droplets of very different sizes also follow very different trajectories, which is harmful for a controlled application of the sprayed product. For example, when spraying a perfume onto a user's skin, droplets that are too large may fall on the user's clothing instead of being projected onto the skin, risking causing permanent stains. .
  • the object of the present invention is in particular to overcome these drawbacks.
  • the invention proposes a manual spraying device according to claim 1.
  • diameter does not necessarily imply that this section is circular.
  • the holes of the front face could if necessary have a polygonal section, for example square, without departing from the scope of the present invention.
  • the aforementioned diameter would be the equivalent diameter of the hole, that is to say the diameter of a circular hole having a section of the same surface as the polygonal hole. If the holes are not of constant section along their length, the diameter in question is the diameter of the minimum section of the holes.
  • the size of the droplets sprayed by the spraying device is controlled and good homogeneity of this size of the droplets is ensured.
  • the aforementioned arrangements also make it possible to at least partially overcome the pressure differences with which the fluid product is fed into the inner chamber of the spray nozzle, since experience shows that the size of the droplets obtained thanks to the present invention is not very dependent on this pressure (the pressure differences in question can come, for example, from differences in the actuating force of a user if the fluid product is supplied by means of a manual pump, or even, when the fluid product is supplied by means of a valve from a tank of product under pressure, the pressure differences in question may come from the fact that the tank has already been partially emptied by previous uses of the spraying device).
  • the invention aims to improve control of the shape of the aerosol obtained at the outlet of the spray nozzle while allowing simplified production of the calibrated holes.
  • the front wall is elastically deformable between a state of rest, in which said front wall is flat, and a state of actuation when fluid under pressure is transferred into the inner chamber, in which said front wall has a convexity facing outward.
  • the holes can be simply made in the flat front wall, each hole possibly having an axis which extends in a plane parallel to a central axis perpendicular to the front wall.
  • the axes of the holes deviate from the central axis so as to have an outward divergence and the fluid product can be sprayed in the form of an aerosol having a high opening angle.
  • the invention aims to improve the control of the distribution of the droplets and of the shape of the aerosol.
  • the holes of the front wall are distributed around a center, each hole extends along an axis inclined with respect to the normal to said front wall at the level said hole, said axis and said normal defining a plane substantially tangent to a circle centered on said central point and passing through the hole, and the axes of all the holes having an inclination with respect to the corresponding normal, and the said axes of all the holes being inclined in the direction of the same angular direction around said central point so as to generate a swirling aerosol when the fluid product is sprayed by said nozzle.
