  • the valve comprises a hollow control rod, also not visible, the opening of the valve being caused by a depression of the control rod. It is not beyond the scope of the present invention when the pressurized container is replaced by a container provided with a pump.
  • the dispensing head 3 comprises two nozzles 10 held by nozzle holders 20, themselves attached to a push button 30, the latter being connected by a hinge portion 40 to a mounting skirt 50 for fixing the assembly on the container 2.
  • the push button 30, the hinge portion 40 and the mounting skirt 50 are, in the example described, made in one piece by molding plastic material and constitute the body of the dispensing head.
  • the mounting skirt 50 is provided, in the lower part, with a bead 51 forming radially inwardly projecting, intended to snap into a groove formed in the upper part of the container 2, conventionally.
  • the pushbutton 30 comprises an axial duct 33 of X axis, opening through a female end 31 inside the mounting skirt 50 and intended to receive with tight fit the upper end of the control rod of the valve.
  • the duct 33 is connected to two radial supply ducts 34, opening through respective male nozzles 38 in the bottom of recesses 35 intended to receive the nozzle-holders 20.
  • the ducts 34 extend in diametrically opposite directions along a Y axis perpendicular to the X axis.
  • the housings 35 communicate with the outside through lateral openings 39 and front openings 41.
  • the lateral openings 39 are made in a wall 42, cylindrical of revolution about the axis X of the pushbutton 30, and have a generally rectangular contour, as can be seen in FIG.
  • the front openings 41 are each formed in a generally planar front wall 43, the two end walls 43 being connected to a central wall 44 extending perpendicularly to an axis Z itself perpendicular to the X and Y axes, as can be seen in Figure 3.
  • the end walls 43 are each at an angle of about thirty degrees with the central wall 44.
  • the front walls 43 and central 44 are connected below a wall lower 45 which extends perpendicularly to the axis X.
  • a bridge of breakable material 48 may optionally connect the cylindrical wall 42 to the upper portion of the mounting skirt 50 to reduce the risk of accidental depression of the push button 30 before the first use. This material bridge 48 is located opposite the hinge portion 40.
  • the end walls 43 and cylindrical 42 are joined by uprights 49.
  • the pushbutton 30 has an upper wall 32 which serves as a bearing surface for the user.
  • Each upright 49 separates the corresponding front aperture 41 and side aperture 39 extending between the top 32 and bottom 45 walls and has a generally triangular cross-section with a large base parallel to the Y direction.
  • the uprights 49 are in contact with two drawers of the mold moved one in the direction Y and the other in the direction Z.
  • a nozzle holder 20 comprises a body 21 made in one piece by molding plastic material.

  • the body 21 of the nozzle holder also has a recess 27, which allows a saving of material.
  • the nozzle holder 20 has, on the opposite side to the housing 22, a cylindrical wall 28 of revolution, intended to be part of the continuity of the cylindrical wall 42 of the push button 30, as will be specified below.
  • the annular groove 26 communicates with the housing 22 via a channel 29 having the same axis K as the center-post 23.
  • Each nozzle holder 20 may be made by injection of thermoplastic material and be easily demolded by virtue of its geometry.
  • the nozzles 10 are preferably vortex channels, the operating principle of such nozzles being well known, in particular by the article Aerosol Age, Volume 20, December 1975.
  • These vortex channel nozzles can be made of In many ways, the product is brought tangentially into a mixing chamber 12 by means of several convergent channels 11, as shown in FIG. 6, the mixing chamber 12 communicating through an outlet port 13 with the outside.
  • the convergent channels 11 are connected to axial channels 14 parallel to the axis K of the nozzle and are supplied with product via the channel 29 of the nozzle holder 20.
  • the front face 24 of the center-post 23 abuts against the bottom 16 of the nozzle 10, so as to force the product to flow in the convergent channels 11.
  • the nozzle holder 20 has an annular boss 60 in front of the center-post 23, projecting radially inwards, to allow the nozzle 10 to snap into place.
  • reliefs can be made on the side wall 17 of the nozzle 10 to improve its anchoring in the nozzle holder 20.
  • the nozzle holder 20 has a truncated corner portion 62, extending the cylindrical wall 28 on the side of the end face 25.
  • the axes K of the nozzles 10 can thus make a non-zero angle with the normals at the end walls 43, as the case may be.
  • the angle between the axes K of the nozzles 10 will be chosen according to the distance at which it is desired that the jets emitted by the nozzles meet, the distance between the orifices 12 of the nozzles 10 being for example between 1.5 and 2.5 cm, for example close to 2 cm, and the angle between the K axes between 40 and 100 °, for example close to 60 °.
  • the user presses on the upper wall 32, which causes the depression of the pushbutton 30 and the actuation of the valve of the container 2.
  • vortex channel nozzles surprisingly makes it possible to obtain a spray having a particle size similar to that of the initial sprays, whereas it might have been feared from the teaching of GB-A-2,153. 444 that the meeting of the particles of the jets causes a fragmentation and a diminution of their size.
  • the invention thus makes it possible to produce a capillary lacquer spray whose particles have a size greater than 20 ⁇ m, for example having an average particle size of around 30 ⁇ m.
  • the invention is also suitable for dispensing a deodorant.
  • the housings receiving the nozzles can be made in a portion of the fixed dispensing head relative to the pressurized container.
