Definitions

  • the invention relates to a valve for the delivery of under Pressurized fluids, especially liquids, pastes, Creams, gels or the like, according to the preamble of Claim 1.
  • valves are generally known and z. B. described in CH-A-325306, US-A-3195569 and DE-A-2329971.
  • the Constructions according to CH-A-325306 and DE-A-2329971 common that no measures are taken to the user show that if you press the Dispensing tube or one connected to the dispensing tube Atomizer cap a second access to the one in the dispensing tube trained discharge channel opens, so that an increased Fluid discharge is reached. In the prior art, it can therefore well possible that the atomizer cap accidentally pushed in too far and accordingly accidentally too much Fluid is discharged.
  • the object of the present invention is accordingly based on the latter construction regarding constructive effort and also functional reliability improve.
  • Valve is used to dispense pressurized fluids, especially liquids, pastes, creams, gels or the like, which is inside a can-like container are located, of which only the Container opening with peripheral edge 10 is shown.
  • This container opening is closed by a lid 11. Between the outer edge of the lid 11 and the A fluid seal 12 is arranged on the container opening edge 10.
  • the interior of the container is indicated by reference number 13.
  • this includes Dispensing valve a fluid-tight at the edge 14 one in the lid 11 trained lid opening 15 attachable valve body 16, an axially displaceable in the valve body, from a Closed position according to FIG. 1 against the Effect of an elastic element, namely here Helical compression spring 17 movable delivery tube 18, and a between the edge 14 of the lid opening 15 and the Valve body 16 closely enclosing the delivery tube 18 arranged ring seal 19 made of rubber or the like elastic sealing material.
  • the ring seal 19 closes in Closed position of the delivery tube according to FIG.
  • Discharge channel 20 first access to a trained in the delivery tube 18 Discharge channel 20 is fluid-tight, the discharge channel 20 extends axially through the delivery tube below Definition of an outer outlet opening 22 and one inner inlet opening 23, which a further or forms second fluid access to the discharge channel 20.
  • the first, access interacting directly with the ring seal 19 opens into the area between the outlet and inlet opening 22, 23 laterally into the discharge channel 20.
  • This lateral first access to the discharge channel 20 is in the form of a Cross bore trained.
  • FIGS. 2 and 3 is in a first 2 only the open position of the delivery tube second access 23 fluidly connected to the container interior 13.
  • both the second access 23 and first access 21 open, d. H. fluidly connected to the container interior 13, via a defined within the valve body 16 fluid chamber 24.
  • In 2 is a smaller amount carried out while in the position shown in FIG Discharge amount is higher. The reason for this is the opening of both Access to the discharge channel 20, d. H. the bigger one Opening cross section compared to the position shown in FIG. 2.
  • the second access 23, which is located on the inside of the container or distal end of the delivery tube 18 is a also cooperating with the ring seal 19 Assigned closing element 25.
  • This closing element 25 is an effective pot-like inside the valve body 16 Element with an annular flange 26 with the ring seal 19 nifty ring projection 27.
  • this pot-like Closing element 25 extends the inner or in Section of the delivery tube 18 located in the valve body 16 into it, with the formation of a fluid channel 28 between the one defining the second access 23 Fluid inlet opening of the discharge channel 20 and the area within the cooperating with the ring seal 19 Ring projection 27.
  • the Fluid channel 28 includes a between dispensing tube 18 and Pot-shaped closing element 25 trained annular space, the by at least three at a predetermined angular distance longitudinal webs 29 arranged from one another is defined.
  • the Longitudinal webs 29 extend in the illustrated Embodiment to the bottom 30 of the pot-like Closing element 25, namely ensuring one Bottom gap 31 between the second access 23 to Discharge channel 20 defining fluid inlet opening on inner or distal end of the delivery tube 18 and the Bottom of the pot-like closing element 25. This is the aforementioned fluid channel 28 ensured.
  • the inside of the container or distal end of the pot-like closing element 25 frustoconical.
  • an atomizer cap 33 is attached on the proximal or outer end of the delivery tube 18 .
  • This has one the first stop 34 cooperating with the container lid 11 for the first opening position of the dispensing tube 18 and a second cooperating with the container lid 11 Stop 35 for the second open position of the 3, wherein the first stop 34 applying a predetermined axial force (arrow 36) can be overcome.
  • the first stop can be at least two, preferably three on the inside of the atomizer cap 33 molded at the same angular distance from each other webs extending approximately parallel to the delivery tube 18 be formed with an outer edge 37 of the Container lid 11 for defining the first open position of the delivery tube 18 cooperate according to FIG. 2.
  • the webs mentioned slide under radial Spreading over the edge 37 formed on the container lid 11 away until the second stop 35 takes effect, which by radially further relative to the webs of the first stop shorter webs arranged on the inside can be defined.
  • the first stop by two diametrically arranged to the dispensing tube 18 Partial ring webs defined during the second or radial inner stop by a continuously closed Ring web is formed, which at the same time for receiving the from the Cover 11 protruding part of the delivery tube 18 is used.
  • the edge of the partial ring webs 38 facing the container lid is rounded on the inside to the radial spread mentioned 3 as soon as a predetermined Axial force in the direction of arrow 36 on the atomizer cap 33 after reaching the first open position according to FIG. 2 is applied.
  • the one with the first stop 34 or the partial ring webs 38 cooperating lid rim 37 is within the outer Limitation of the lid 11 located edge. This forms by contact of the cover 11 on a peripheral flange 39 of the valve body 16 such that the valve body 16 on Cover 11 is firmly fixed with the interposition of already mentioned ring seal 19.
  • the recess of the closing element 25 is the inside of the container or distal end portion of the delivery tube 18 preferably fitted under press fit.
  • the first access 21 is in this Position approximately at the level of the ring seal 19. With this Position is the ring projection 27 of the ring flange 26 of the Pot-like closing element 25 from the inside of the container the ring seal 19 already lifted off, so that a Fluid connection between the container interior 13 and the further or second access 23 to the discharge channel 20 arises.
  • the dispensing tube 18 shown in FIG. 3 is still further pressed into the inside of the container gives the ring seal 19 also free the first access 21 to the discharge channel 20, see above that the fluid connection between the interior of the container 13 and Discharge channel 20 of the dispensing tube 18 through both entrances 21, 23 takes place.
  • Fluid seal 12 and the cover 11 are made of plastic.
  • the aforementioned seals are preferably made of rubber or the same elastic sealing material.
  • the lid 11 is preferably made of aluminum sheet, as is the Containers not shown.
  • Pot-like closing element 25 also has the advantage that the first opening position of the dispensing valve also through the dispensing tube and atomizer cap are tilted to the side is achieved.
  • a fluid connection between the Container interior 13 and the discharge channel 20 via the second Access 23 is already reached when part of the Ring projection 27 from the inside of the container Ring seal 19 stands out.
