Definitions

  • the invention relates to a spray head for an aerosol container with the Features of the preamble of claim 1.
  • the known spray head from which the invention proceeds (WO 03/051522 A2), has the special feature that the spraying of the fluid takes place nozzle-free.
  • the fluid is under high pressure in a capillary with very little Diameter introduced and passed in the capillary to an outlet end and sprayed from there nozzle-free. It is essential that the use of a Capillary for this form of spraying a liquid causes the Fluid also low in solvents and thus in subjective sensation "dry” can be sprayed.
  • This novel spraying low-solvent Liquid is now referred to as "LoFlo". Characteristic This is not only because the liquid that is sprayed, low in solvents is sprayed, but that the spraying with relatively little Propellant gas can be made.
  • Spray heads for aerosol cans have been in an unmanageable way for decades Abundance of embodiments known, among which only a few examples to mention are (EP 0 409 497 A1, US 5,388,730 A, US 3,848,778 A).
  • In classic spray heads is a non-acting as a capillary Tubes for transporting the liquid to be sprayed in the spray head.
  • a spray nozzle At the At the end of this tube is a spray nozzle, which is the way the spraying of the liquid causes.
  • the pressure build-up for the spraying of the liquid at the nozzle retroactively so in the tube.

  • the fluid outlet valve is part of Spray head.
  • This spray head itself has a down to the fluid container into reaching dip tube, in which a capillary far into the Fluid tank extends into it.
  • the capillary itself puts together with a Sliding the fluid outlet valve.
  • the spray head is the capillary from Entry end to the outlet end in an arc of about 90 ° running arranged, wherein the sheet course by interlocking outer and Internal guides is guaranteed.
  • This construction is in total for aerosol containers not suitable with conventional fluid outlet valves.
  • the spray head itself provides the guidance to the capillary, which in itself has an elongated, straight shape, in the necessary Arc for realizing the correct orientation of the exit end of the To force capillary.
  • the spray head is an independent component, the in a conventional female fluid outlet valve in a valve lifter terminates, in which the capillary extends, in a conventional male Fluid outlet valve ends in a receptacle into which the capillary extends.

  • the arc shape of the capillary 4 in the spray head 1 can be on different Realize ways. This becomes the individual embodiments explained in more detail.
  • the material of the spray head 1 choose plastic material like that from practice for spray heads in the speech standing species has long been known. Furthermore, it is recommended that the Capillary 4 from a feasible in an arc 7 material, in particular Metal, or, preferably and so also predominantly provided, from Produce plastic. It should be taken into account, what the beginning of the Pressure reduction before the capillary 4 has been explained. In the capillary 4 itself There is no excessively high pressure, so that an execution of the Capillary 4 plastic is practically possible without further notice.
  • the length of the Capillary 4 is in some connection to the inner diameter the capillary 4 and should be about 10 mm to about 100 mm, preferably about 25 mm to about 50 mm.
