Definitions

  • the invention relates to a valve for dispensing pressurized fluids, in particular liquids, pastes, creams, gels or the like, according to the preamble of claim 1.
  • Valves of this type are generally known, in particular in the form of so-called aerosol valves.
  • a disadvantage of these known constructions is that the discharge quantity cannot be controlled or is difficult to control.
  • the present invention has for its object to provide a valve of the type mentioned, which allows precisely controlled a different discharge amount, namely on the one hand a low discharge amount and on the other hand a high discharge amount (low and high discharge).
  • the dispensing tube has a first and second access to the discharge channel, both entrances being assigned a common sealing element, namely the ring seal arranged between the valve body and the container lid.
  • the second access to the discharge channel is also a separate locking element assigned so that in a first opening position of the dispensing tube only the second access is open for a reduced fluid discharge, while in a second opening position both accesses to the discharge channel of the dispensing tube are open for an increased fluid discharge.
  • valve shown in FIGS. 1 to 3 in longitudinal section serves to dispense pressurized fluids, in particular liquids, pastes, creams, gels or the like, which are located within a can-like container, of which in FIGS. 1 to 3 only the container opening with peripheral edge 10 is shown.
  • the dispensing valve comprises a valve body 16 which can be fastened in a fluid-tight manner at the edge 14 of a cover opening 15 formed in the cover 11 and which is axially displaceable in the valve body from a closed position according to FIG. 1 against the effect of an elastic one Elements, namely here helical compression spring 17 movable dispensing tube 18, and an annular seal 19 made of rubber or similar elastic sealing material arranged closely surrounding the dispensing tube 18 between the edge 14 of the lid opening 15 and the valve body 16.
  • the ring seal 19 closes a first access to a discharge channel 20 formed in the discharge tube 18 in a fluid-tight manner, the discharge channel 20 extending axially through the discharge tube, defining an outer outlet opening 22 and an inner inlet opening 23, which one forms further or second fluid access to the discharge channel 20.
  • the first access which interacts directly with the ring seal 19, opens laterally into the discharge channel 20 in the area between the outlet and inlet openings 22, 23.
  • This lateral first access to the discharge channel 20 is designed in the form of a transverse bore. In the closed position of the delivery tube, the transverse bore or the first access 21 is located in the area of the ring seal 19, preferably just above it, as shown in FIG. 1.
  • both the second access 23 and the first access 21 are open, ie fluidly connected to the container interior 13, specifically via a fluid chamber 24 defined within the valve body 16 a smaller amount is discharged in the position shown in FIG. 2, while the discharge amount is higher in the position shown in FIG. 3.
  • the reason for this is the opening of both entrances to the discharge channel 20, ie the larger opening cross section compared to the position according to FIG. 2.
  • a closure element 25, which also cooperates with the ring seal 19, is assigned to the second access 23, which is located on the inside of the container or the distal end of the delivery tube 18.
  • This closing element 25 is a pot-like element effective within the valve body 16 with an annular flange 26 with an annular projection 27 facing the ring seal 19.
  • the inner portion of the dispensing tube 18 or the valve body 16 located in the valve body 16 extends into it, with the formation of a Fluid channel 28 between the fluid inlet opening of the discharge channel 20 defining the second access 23 and the area within the annular projection 27 cooperating with the ring seal 19.
  • the fluid channel 28 comprises an annular space formed between dispensing tube 18 and pot-like closing element 25, which is defined by at least three longitudinal webs 29 arranged at a predetermined angular distance from one another.
  • the longitudinal webs 29 extend to the bottom 30 of the pot-like closing element 25, specifically while ensuring a bottom gap 31 between the fluid inlet opening defining the second access 23 to the discharge channel 20 at the inner or distal end of the dispensing tube 18 and the Bottom of the pot-like closing element 25.
  • the aforementioned fluid channel 28 is thus ensured.
  • the container interior or distal end of the pot-like closing element 25 is frustoconical.
  • the helical compression spring 17 urging the delivery tube 18 in the closed position according to FIG. 1 is supported on the valve body 16 (not shown) and on the pot-like closing element 25, namely on the side of the annular flange 26 facing away from the annular projection 27.
  • a fluid throttle in the form of a constriction 32 is also located between the first lateral access 21 and the further or second access 23 to the discharge channel 20 of the dispensing tube 18.
  • An atomizer cap 33 is attached to the proximal or outer end of the delivery tube 18. This has a first stop 34 cooperating with the container lid 11 for the first opening position of the dispensing tube 18 and a second stop 35 cooperating with the container lid 11 for the second opening position of the dispensing tube 18 according to FIG. 3, the first stop 34 applying a predetermined one Axial force (arrow 36) can be overcome.
  • the first stop can be formed by at least two, preferably three webs integrally formed on the inside of the atomizer cap 33 at the same angular distance from one another and extending approximately parallel to the dispensing tube 18, which have an outer edge 37 of the container lid 11 to define the first opening position of the dispensing tube 18 cooperate according to FIG. 2.
  • the first stop is arranged diametrically to the dispensing tube 18 Partial ring webs defined, while the second or radially inner stop is formed by a continuously closed ring web, which at the same time serves to receive the part of the delivery tube 18 protruding from the cover 11. 3, as soon as a predetermined axial force in the direction of arrow 36 is applied to the atomizer cap 33 after reaching the first opening position according to FIG. 2.
  • the lid edge 37 cooperating with the first stop 34 or the partial ring webs 38 is an edge located within the outer boundary of the lid 11. This is formed by contact of the cover 11 on a peripheral flange 39 of the valve body 16 in such a way that the valve body 16 is firmly fixed to the cover 11 with the interposition of the ring seal 19 already mentioned.
  • the pot-like recess of the closing element 25 is the inner or distal end section of the Dispensing tube 18 preferably fitted under a press fit.
  • the ring seal 19 closes the first access 21 to the discharge channel 20 in a fluid-tight manner.
  • the first access 21 is in this position approximately at the level of the ring seal 19.
  • the annular projection 27 of the ring flange 26 of the pot-like closing element 25 is already lifted off the inside of the ring seal 19, so that a fluid connection between the container interior 13 and the Another or second access 23 to the discharge channel 20 is created.
  • the ring seal 19 also opens the first access 21 to the discharge channel 20, so that the fluid connection between the inside of the container 13 and the discharge channel 20 of the discharge tube 18 takes place through both entrances 21, 23. Accordingly, a higher discharge quantity is then achieved.
  • fluid seal 12 and the cover 11 are made of plastic.
  • the aforementioned seals are preferably made of rubber or the like elastic sealing material.
  • the lid 11 is preferably made of aluminum sheet, as is the container, not shown.
  • the pot-like closing element 25 assigned to the second access 23 to the discharge channel 20 also has the advantage that the first opening position of the dispensing valve is also achieved by tilting the dispensing tube and atomizer cap sideways.
  • a fluid connection between the interior of the container 13 and the discharge channel 20 via the second access 23 is already achieved when a part of the ring projection 27 lifts off from the inside of the container of the ring seal 19.
