Definitions

  • the present invention relates to a device for atomizing a preferred cosmetic liquid according to the preamble of claim 1, a spray head according to the preamble of claim 10 and a use of such a device.
  • a spray head or device is known from DE 1 750 671 A1 known.
  • cosmetic liquid is to be understood in a narrow sense hair spray, hair lacquer, a deodorant, a foam, a gel, a paint spray, a sunscreen or skin care agent o. The like.
  • other personal care products cleansing products, cosmetics o. The like.
  • suspensions and fluids, especially with Crasphasen includes.
  • other liquids such as air freshener, and in particular also technical fluids and fluids, such as rust remover o. The like., Are used.
  • cosmetic liquid is often referred to below.
  • a device for atomizing a cosmetic liquid, such as hair spray wherein a container containing the liquid comprises a valve, on the connecting piece of a spray head can be plugged.
  • the valve Upon depression of the spray head, the valve is opened, wherein the liquid flows through a throttle channel forming a throttle radially into an axial recess of the connector and then into the spray head.
  • the connecting piece here simultaneously forms an actuatable valve element and is preferably injection molded or injection-molded in one piece from plastic.
  • the production of the throttle channel is relatively expensive, since a separately movable Dom o. The like. Must be used.
  • the tolerances for the throttle or the throttle channel are very low in order to ensure the required or desired throttle effect and thus the desired spray behavior of the device can. This applies in particular to the cross section or diameter of the throttle channel, since the length of the throttle channel is only relatively small, in particular due to its radial orientation. In mass production, compliance with tolerances is relatively difficult. This is only valid right when liquids that are pressurized, for example, by volatile, highly flammable, especially organic propellants, by compressed gas and / or by carbon dioxide, even stronger throttle effects, so even smaller throttle cross-sections or diameters require.
  • Another disadvantage of the known device is that different throttle effects, ie different throttle channel cross sections, and thus different valves and usually also different spray heads are required for different liquids or products to be atomized.
  • the DE 1 750 671 A which relates to the starting point of the present invention, describes a spray head with a radially open, half-round recess.
  • the spray head is attached to a valve, so that the recess is partially covered radially by a cylindrical receiving portion of the valve. There remains a radial distance at the end of the receiving portion from the discharge end of the recess, so that a radial channel is formed, which acts as a throttle.
  • the present invention has for its object to provide a device and a spray head for atomizing a preferably cosmetic liquid and a use of such a device, wherein in a very simple and thus cost-effective manner, a throttle with, if necessary, very strong throttle effect with high accuracy is reached.
  • a basic idea of the present invention is that the spray head has or forms a second or the only restriction for the liquid flowing through upstream of its nozzle. This leads to several advantages. By using a spray head with a desired throttling effect, the same valve can often be used for various applications. This simplifies the manufacture or assembly of the proposed devices. Further, by the proposed embodiment of the single or additional throttle on the spray head as needed stronger throttle effect can be achieved with high tolerances, for example, by combination or series connection of the first throttle valve and the second throttle on the spray head
  • the term "at the spray head 'with respect to the arrangement of the (second) throttle also to understand that the throttle also at the transition from the valve to the spray head, especially from the interaction of a fitting of the container side valve and the spray head in assembled state, can be formed.
  • the throttle has a throttle channel, which is initially prepared in the form of a longitudinally open, in particular groove or notch-like recess preferably by injection molding and only then by a separately prepared connector, in particular when attaching the spray head or at another assembly of the device, longitudinally at least partially covered.
  • a throttle channel is very easy to produce, in particular by injection molding and with a very high tolerance by a corresponding web in the injection mold o. This is especially true when the throttle channel is formed along a preferably cylindrical or hollow cylindrical portion. The throttle channel can then without any additional effort, in particular with a very simple injection mold without moving Dom o. The like., Are produced.
  • Another advantage of said throttle channel is that its effective length, ie cover length or total length, and thus the throttle effect or the flow resistance of the throttle can be varied very easily and with high accuracy.
  • the proposed design of the throttle with the first longitudinally open throttle channel is preferably provided at the spray head or transition from the valve to the spray head, in particular wherein the throttle channel is at least partially covered during assembly or when attaching the spray head to the container or its valve, creating a additional assembly or manufacturing step is not required.
  • the proposed throttle design may additionally or alternatively be used to manufacture another throttle in the device for atomizing the liquid or a similar device can be used.
  • Fig. 1 shows a schematic sectional view of a proposed device 1 for atomizing a preferably cosmetic liquid 2 o. The like.
  • the device 1 has a container 3 for the liquid 2 and a preferably frontally arranged on the container 3 valve 4.
  • a spray head 5 is mounted, which is mounted in particular after filling of the container 3 with the liquid 2.
  • the spray head 5 is attached. However, it can also be attached in any other suitable manner - if necessary releasably.
  • the spray head 5 has a nozzle on the discharge side 6 for atomizing the liquid 2 and output.

  • the container 3 or the liquid 2 contains a suitable propellant, preferably a volatile and / or flammable propellant, compressed gas and / or carbon dioxide.
  • the valve 4 has an axially displaceable valve element 7 and a spring 8 biasing the valve element 7 upward or outwards into the closed position in the illustrated embodiment.
  • the valve element 7 and the spring 8 are arranged in a valve housing 9, to which a riser 10 for receiving the liquid 2 is connected in the illustrated example.
  • a preferably at least substantially annular sealing element 11 forms a valve seat 13 together with an adapted recess 12 on the valve element 7.
  • valve 4 - in the illustrated embodiment Upon actuation of the valve 4 - in the illustrated embodiment by depressing the spray head 5 - opens the valve 4, as in Fig. 2 schematically, but without container 3 and without liquid 2 shown.
  • the pressurized liquid 2 can then flow through an adjoining the valve seat 13, in the embodiment, radially extending passage 14 with a subsequent first throttle 15 in an axial recess 16 of the valve element 7.
  • the axial recess 16 extends into a subsequent to the valve element 7, axially open connector 17 for the spray head. 5

  • the valve 4 is in particular a conventional valve 4 to which conventional spray heads 5 can be connected.
  • other valve designs are feasible.
  • the spray head 5 has, as proposed, a (second) throttle 18 upstream of the nozzle 6.
  • the second throttle 18 is arranged on the supply side, in particular in the region of a feed port 19 of the spray head 5 in the illustrated example.

  • the longitudinally open design of the throttle channel 18 initially allows a relatively simple production, with very small flow areas can be achieved with low tolerances. This can be explained by the fact that in place of a very thin mandrel o. The like. Now a much more stable web or projection, which may extend over the entire length of the throttle channel 22 to be formed on a wall of a mold can be used.
