Definitions

  • the present invention relates to a metering valve for dispensing a preferably cosmetic liquid according to the preamble of claim 1, a device with such a metering valve, and a method for producing such a metering valve.
  • 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, in particular with gas phases are preferably included.
  • 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 the metered atomization of a cosmetic liquid comprising a metering valve with a movable valve element in a valve housing.
  • the valve element together with the valve housing forms an inlet-side inlet valve and a discharge-side outlet valve.
  • the valve element is preferably provided with an attached spray head o. The like.
  • the valve element is moved axially, whereby initially the inlet-side inlet valve of the metering valve is closed and only then the discharge-side outlet valve of the metering valve is opened. Then, the liquid preferably containing a blowing agent can escape from the metering chamber formed in the valve housing and be atomized and dispensed by the connected spray head.
  • a seal is molded onto the movable valve element, which seals axially with the inlet valve closed.
  • the known metering valve does not allow optimal sealing.
  • the US 3,073,489 A shows a metering valve with the features of the preamble of claim 1.
  • the present invention has for its object to provide a metering valve and a device for the metered delivery of a preferably cosmetic liquid and a method for producing such a metering valve, wherein the metering valve allows optimal sealing and is universally applicable.
  • the valve element has a resilient in the direction of movement spring portion and a subsequent head portion, wherein the head portion preferably forms the inlet valve and in particular carries the preferably molded sealing element.
  • the sealing element is preferably made of a softer or more elastic material than the valve element and the valve housing. This allows a much more stable design of the metering valve, in particular the valve housing, which can therefore withstand better higher blowing agent and filling pressures accordingly. Therefore, the proposed metering valve and a device provided with such a metering device are universally applicable.
  • the sealing element is molded directly onto the valve element. This can be done, for example, directly in the injection mold for the valve element. If necessary, the sealing element can also be used as a prefabricated part in the injection mold and the valve element are molded onto the sealing element. In both cases, a particularly simple and cost-effective production is made possible, wherein the assembly can be done in the usual manner without additional mounting step for the sealing element.
  • the sealing element is arranged in the region of a free end on the valve element. This is in particular a corresponding end-side arrangement of the inlet valve and a possible attachment of the sealing element on the valve element beneficial.
  • the sealing element, the valve element and the valve housing are each injection molded from plastic to enable a cost-effective mass production.
  • the injection molding is done with such precision and such a choice of materials that no post-processing to achieve the desired sealing effect is required.
  • the sealing element is self-locking. This can be achieved, for example, in that the sealing element engages in a preferably undercut recess of the valve element or the valve housing. However, this is achieved in a particularly preferred manner by the sealing element being injection-molded or injected directly onto the valve element or the valve or vice versa, in order to form a non-detachable composite.
  • the metering valve is used for metered delivery of a cosmetic liquid containing particles, wherein distributed projections in a metering chamber of the metering valve for temporary deposition the particles are used to counteract a bottom-side settling of the particles and in particular clogging of the inlet valve, wherein the deposited on the projections particles are discharged by the liquid in the discharge.
  • This allows a better distribution of the particles in the discharged liquid.
  • This is beneficial for particle-containing formulations or suspensions, which are increasingly being used, in order to be able to ensure as uniform a distribution as possible and thus uniform properties.
  • Fig. 1 shows a schematic sectional view of a proposed device 1 with a metering valve 2 for the metered delivery of a preferably cosmetic liquid 3 o. The like.
  • a discharge of the liquid 3 via a not shown, connected to the metering valve 2 - preferably plugged it - Spray head for atomizing and dispensing the liquid 3.
  • the liquid 3 is under pressure or can be pressurized.
  • the liquid 3 contains a blowing agent, preferably a volatile and / or combustible blowing agent, compressed gas, carbon dioxide or the like.
  • the cosmetic liquid 3 in the aforementioned sense is particularly preferably a particle-containing mixture or suspension.
  • the device 1 further comprises a container 4 for the liquid 3 and a lid 5 carrying the metering valve 2.
  • the metering valve 2 has a movable valve element 6 and a valve housing 7.
  • the valve element 6 is in the illustrated embodiment axially - in the representation of FIG. 1 vertical - in the valve housing 7 movably guided and forms the discharge side a projecting connector 8 for connection of the spray head not shown o.
  • the metering valve 4 has an inlet-side inlet valve 9, a discharge-side outlet valve 10 and a metering space 11 formed therebetween in the valve housing 7.
  • a valve member 6 associated return spring 12 is arranged, which biases the valve element 6 in the illustrated, unactuated position, ie here upwards.
  • the exhaust valve 10 In the unactuated position, the exhaust valve 10 is closed and the intake valve 9 is opened. In this state, the dosing chamber 11 is filled with the liquid 3 (in the figures, this is not shown for reasons of simplification), wherein the liquid 3 from the container 4 via an inlet-side riser 13 through the open inlet valve 9 in the dosing 11 or one respected can flow.
  • the inlet valve 9 Upon actuation of the valve element 6 - ie pushing down of the valve element 6 against the force of the return spring 12 - the inlet valve 9 is first closed and only then the exhaust valve 10 is opened. In this actuated state, the liquid 3 located in the dosing chamber 11 can then be discharged via the opened outlet valve 10, in particular due to the said blowing agent to flow independently and, for example, sprayed or atomized by the spray head, not shown, connected to the connecting piece 8. Accordingly, the metering valve 2 dispenses only a specific or metered quantity of liquid 3 with each actuation.
  • valve element 6 and the valve housing 7 are preferably each formed in one piece and injection molded from plastic, in particular from a relatively hard or rigid plastic, such as polyamide or polyoxymethylene (POM).
  • plastic in particular from a relatively hard or rigid plastic, such as polyamide or polyoxymethylene (POM).
  • POM polyoxymethylene
  • a sealing element 14 made of a softer or more elastic material than the valve element 6 and the valve housing 7 is also provided according to the proposal between the valve element 6 and the valve housing.
  • the sealing element 14 is molded onto the valve element 6, preferably directly in the injection mold used for producing the valve element 6 or in a separate injection mold.
  • the sealing element 14 may for example also be inserted as a prefabricated part into the injection mold and the valve element 6 may be injection-molded or the sealing element 14 may be attached to the prefabricated valve element 6.
  • the sealing element 14 is also preferably injection molded, in particular of a suitable elastomer, preferably of a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU) or high pressure produced low density polyethylene (LDPE).
  • a suitable elastomer preferably of a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU) or high pressure produced low density polyethylene (LDPE).
  • sealing member 14 forms no separate part and therefore does not require a separate assembly step and beyond the further advantage that a very good seal between the sealing member 14 and the associated valve member 6 or Valve housing 7 can be reached without additional measures.
  • the sealing element 14 is arranged on the valve element 6 and, in the illustrated embodiment, preferably has a frusto-conical, conical, spherical, hemispherical or rounded insertion region 15 in order to be inserted into a corresponding sealing section of the valve housing 7 to facilitate sealing against the sealing element 14 with the inlet valve 9 closed.
  • the sealing element 14 is arranged at a free end of the valve element 6 such that in the unactuated state, an axial inlet channel 17 in the valve housing 7 to the dosing chamber 11 is not blocked.
  • the valve element 14 In the actuated state - ie when depressed valve element 6 - the valve element 14 is preferably at least partially inserted with a front end of the valve element 6 in the supply channel 17 for radial and / or axial sealing at a sealing portion of the valve housing 7.
  • other valve designs are possible, for example, a plate-like design and / or an axial seal.
  • the one-piece valve element 6 has, in the region of its front or free end, a spring section 21, which is resilient in the axial direction or movement direction B, and an adjoining head section 22.
  • the sealing element 14 is preferably arranged at least substantially exclusively on the front side of the head portion 22, preferably molded.
  • the inlet valve 9 seals at least substantially axially by the sealing element 14 comes to rest on actuation of the valve element 6 at a suitable, preferably conical shoulder region 16 or other valve seat of the valve housing 7, whereby the inlet valve 9 closes.
  • the spring portion 21 is axially compressed and finally the exhaust valve 10 is opened. In this compressed state, the force exerted by the spring portion 21, acting in the closing direction of the intake valve 9 spring force is then sufficiently high to keep the inlet valve 9 against the pressure prevailing in the container 4 closed.
  • the spring section 21 permits an improved sealing between the sealing element 14 and the valve housing 7 or a valve seat, since the sealing element 14 can rest optimally uniformly on the valve seat, In particular, wherein radial and axial tolerances and tilting can be compensated or tolerated.
  • the outlet valve 10 has in the illustrated example, a separate sealing element 18, which is in particular annular and is held by the valve housing 7 against a ring portion of the lid 5 sealing.
  • the separate sealing element 18 seals radially to a shaft portion of the valve element 6 or fitting 8 from.
  • the outlet valve 10 is closed and accordingly no liquid 3 can emerge from the dosing chamber 11 on the discharge side.
  • valve element 6 When the valve element 6 is actuated, the valve element 6 or the connecting piece 8 is displaced axially in such a way that a radial passage 19 moves past the separate sealing element 18 into the interior of the valve housing 7, ie is released towards the metering chamber 11 (this position is not shown) ).
  • the outlet valve 10 is opened, and liquid 3 can flow out of the metering chamber 11 through the passage 19 in an axial recess 20 and through this from the connector 8 also in the spray head o.
  • the valve element 6 or the connecting piece 8 When the valve element 6 is actuated, the valve element 6 or the connecting piece 8 is displaced axially in such a way that a radial passage 19 moves past the separate sealing element 18 into the interior of the valve housing 7, ie is released towards the metering chamber 11 (this position is not shown) ).
