Definitions

  • the present invention relates to a fluid spray head having an improved shutter of the spray orifice, and in particular a improved shutter adaptable to standard type spray devices.
  • the present invention applies more particularly to fixed shutters which are deform under the effect of the pressure of the product during the actuation of the device of spray.
  • the part producing the spraying the liquid to be dispensed has a particularly critical geometry that does not should not be tampered with in order to obtain a properly atomized spray.
  • This part is usually formed in the end wall of the spray head, in the form of narrow channels arranged at different angles and connected to the spray orifice. The liquid is thus forced to create a vortex when it passes to through said spray orifice.
  • the bottom of these channels can be formed either by the end of a piece rigidly fixed in the expulsion channel, either by the shutter himself.
  • NL-6 918 423 discloses a movable shutter incorporating a propeller exterior. This shutter moves away from the dispensing orifice when the actuation thus substantially modifying the geometry of the spray profile at timing of the distribution.
  • the present invention aims to provide a shutter of the orifice of spraying a fluid spray device that does not reproduce the disadvantages mentioned above.
  • the present invention aims to provide a spray head with a shutter, and whose spraying profile is simple, reliable and little expensive to make.
  • Another object of the present invention is to provide a spray head comprising a shutter capable of producing a tight sealing of the device and a reliable opening when actuating the device.
  • Another object of the present invention is to provide a spray head comprising such a shutter which not significantly alter the geometry of the device's spray pattern during its opening.
  • Another object of the present invention is to provide a spray head comprising a shutter which makes it possible to minimize the size of the dead volume and therefore avoids the need for a complex priming of the spray pump and / or the use of special pumps which would not be standard type. In addition, it helps to ensure better protection of the liquid to be dispensed.
  • the present invention also aims to provide a head of spray having a shutter that is simple and can costly to manufacture and to assemble.
  • the subject of the present invention is therefore a spray head for spraying fluid through a spray orifice, said head having a channel expulsion and a shutter fixedly disposed in the expulsion channel upstream of said spray orifice, said shutter having a fixed portion relative to the spray orifice and an elastically deformable portion supporting an element which, at rest, closes the spray orifice, and which, when the elastically deformable is deformed, opens the spray orifice, said head of spraying further comprising a spraying profile, characterized in that said spray profile is formed at least on said elastically deformable portion said shutter.
  • said spray profile comprises one or more channels spray.
  • said spray profile comprises a chamber of swirling around said shutter member.
  • said expulsion channel is substantially cylindrical and comprises a substantially cylindrical hollow internal insert, said shutter having a portion substantially cylindrical fixed around said insert, said portion elastically deformable said shutter forming the bottom of said cylindrical portion of the shutter, said spray pattern being formed on said cylindrical portion and / or said deformable part of the shutter.
  • said cylindrical portion of the shutter comprises a plurality ribs spaced apart from each other on the periphery and defining between them a plurality of first spray channels.
  • said first channels extend vertically or obliquely on said cylindrical portion of said shutter.
  • said deformable portion comprises a plurality of projections defining between them a plurality of second spray channels and / or a swirling chamber.
  • the shutter is fixed on the insert by a peripheral groove formed in the cylindrical portion of the shutter which cooperates with a projection annular of said insert, such that no compression force is exerted by the upper end of the insert on the deformable part of the shutter, in the position of rest of the shutter.
  • the present invention also relates to a spraying device comprising a spray head as defined above.
  • the shutter according to the invention comprises mainly a closure member 9 disposed on an elastically deformable portion 10 of the shutter.
  • the closure element 9 advantageously, embodied in the form of a conical needle, is movable between a closed position of the dispensing orifice 7, which is shown in FIG. 3 and an opening position of said orifice of 7.
  • the shutter is fixedly placed inside the expulsion channel 5, 6 of a spray head 1 of a spray device of fluid product, upstream of the dispensing orifice 7.
  • the shutter element 9, attached to said elastically deformable portion 10 of the closure member is elastically urged to rest towards its closed position.
  • the pressure created by the product deforms the elastically deformable portion 10 of the shutter, which moves the shutter member 9 from its shutter position to its opening position allowing the expulsion of the product through the dispensing orifice.
  • this displacement of the closure member 10 is axially away from the orifice 7.
  • the closure member of the present invention is arranged in the expulsion channel upstream of the dispensing orifice and alone the shutter element 9 is moved by the elasticity of the elastically deformable 10.
  • said elastically deformable portion 10 preferably forms a radial flange disposed near said dispensing orifice 7, said deformation being made from a predetermined pressure exerted by said produced on said elastically deformable portion.
  • this part Elastically deformable material 10 is made of an elastomeric material.
  • the closure element 9 is made in one piece together with said part elastically deformable 10, the whole being preferably made of a material elastomer.
  • the shutter of the invention is very simple to manufacture and inexpensive while being perfectly reliable and waterproof.
  • any material suitable flexible can be used for the shutter, or at least for its part elastically deformable 10.
  • the bottom wall of the spray head 1 is made of smooth or flat way, and this is the shutter that incorporates a swirl profile.
  • the shutter of the invention has a general shape similar to that of the shutter disclosed in FR 2,767,311 which is incorporated by reference.
  • the shutter therefore comprises a substantially cylindrical portion 3, the portion elastically deformable forming the bottom of said cylindrical portion 3.
  • the shutter has a spraying profile both on the part cylindrical 3 and the elastically deformable portion 10.
  • the cylindrical portion comprises a plurality of ribs 16 defining between them first channels of These channels 6 may be vertical, as shown in FIGS. 1 and 2, but they could also be oblique.
  • the elastically deformable portion comprises a plurality of projections 18 defining between them second spray channels 8 and a chamber of swirl 19 around the shutter element 9. This is a profile of usual spray.
  • the pattern of the spray pattern can be any.
  • the profile of spray on the cylindrical portion 3 of the shutter may be sufficient to ensure a good spray, especially when the space between the bottom wall of the head and the elastically deformable part is minimal.
  • the geometry of the spray channels 6 and / or 8 is not or that very little modified by the displacement of the shutter element 9 from its closed position towards its open position.
  • the shutter of the present invention thus makes it possible ensure good spraying despite its presence at the orifice of distribution.
  • FIG. 3 shows an advantageous embodiment of the shutter according to the present invention.
  • the shutter is fixed around the insert 4, inside a spray head 1 of the standard type.
  • Fixing the shutter on the insert is here made at the level of the part cylindrical 3 of the shutter, for example by means of an internal annular groove 31 cooperating with an annular lateral projection 41 formed on the insert 4.
  • an internal annular groove 31 cooperating with an annular lateral projection 41 formed on the insert 4.
