Definitions

  • the invention relates to a valve for dispensing pressurized fluids, in particular liquids, pastes, creams or gels or the like, according to the preamble of claim 1.
  • a valve of this type is described in AT 388 715 B. It is a valve that is widely used commercially. Such a valve is to be described in more detail with reference to FIG. 5.
  • This valve which is provided with the reference number 30, has a valve body 33 which can be fastened in a fluid-tight manner at the edge 31 of a lid opening formed in a container lid 32 and an axially displaceable in the valve body from a closed position corresponding to FIG. 5, counter to the action of an elastic element, namely here Helical compression spring 34 movable delivery tube 35, and a between the edge 31 of the lid opening and the valve body 33 closely surrounding the delivery tube 35 ring seal 36 made of rubber or the like elastic sealing material.
  • an elastic element namely here Helical compression spring 34 movable delivery tube 35
  • a closing element 38 which interacts with the ring seal 36, is assigned to a fluid access formed at the inner end of the dispensing tube 35.
  • This closing element 38 is a pot-like element effective within the valve body 33 with an annular flange 39 with an annular projection 40 facing the ring seal 36.
  • the inner portion of the delivery tube 35 or located in the valve body 33 extends into it.
  • the delivery tube 35 is fixed within the pot-like closing element 38 by a press fit, that is to say a frictional engagement. If the dispensing tube 35 is pressed into the interior of the container, ie into the lid opening, the pot-like closing element 38 is carried along in a manner contrary to the action of the helical compression spring 34.
  • valve body 33 is fluidly connected to the interior of the container via a fluid channel 41 that opens into the interior of the container, a tube-like tube 42, preferably extending to the bottom of the container, not shown, being connected to the fluid channel 41.
  • a circumferential fluid seal 43 is also assigned to the outer edge of the cover 32, which is clamped between the edge of the cover and the edge of the container opening in the assembled state.
  • the state of this seal before assembly is shown in Figure 5 on the left side and after assembly on the right side.
  • the inner or lower peripheral edge of the delivery tube 35 in FIG. 5 is formed by four claws 44, which are evenly distributed over the circumference and are placed within an annular bottom groove of the pot-like closing element 38 under the press fit already mentioned above.
  • the clearances between the claws 44 defined define the fluid body 37 of the delivery tube 35 inside the valve body.
  • the strength of the claws 44 for fixing the delivery tube 35 within the pot-like closing element 38 is sufficient when the delivery tube 35 is acted upon axially. If, however, an opening of the dispensing tube 35 by tilting it laterally into consideration, the known construction would pose the risk of that the delivery tube breaks in the area of the claws 44 or in the area of the connection thereof to the delivery tube. The same can of course happen if the dispensing tube 35 is accidentally tilted in the construction according to FIG.
  • the present invention is based on the object of providing a dispensing valve which is distinguished by a simpler connection between dispensing tube and pot-like closing element in terms of production and assembly technology, and in which the dispensing valve is also particularly stable against tipping.
  • the first subtask is solved according to the invention by the characterizing features of claim 1.
  • Claim 2 relates to the second subtask.
  • the pot-like closing element has a centrally protruding pin, over which the delivery tube can be pushed with practically its entire length is increased resistance to bending stress, such as occurs when the dispensing tube is tilted. While in the known valve according to FIG. 5, when the dispensing tube 35 is tilted, the corresponding tilting moment is transmitted to the pot-like closing element only via a relatively short pin, this force and torque transmission takes place according to the invention over the entire length of the centrally projecting pin, and thus over the entire length the delivery tube directly onto the pot-like closing element.
  • the centrally protruding pin has the effect that the tilting moment exerted on the delivery tube is transmitted almost directly to the pot-like closing element.
  • the valve 10 for the delivery of pressurized fluids shown in schematic longitudinal section in FIG. 1, has a delivery tube 11 which can be moved with a valve body (not shown) from a closed position against the action of an elastic element, also not shown, in particular a helical compression spring on which a pot-like closing element 12 is associated with a ring seal closely surrounding the delivery tube corresponding to the ring seal 36 according to FIG. 5 made of rubber or the like.
  • the dispensing tube 11 defines a dispensing opening 13 at its end that is accessible from the outside after assembly. At the end opposite this dispensing opening 13, the dispensing tube 11 has a circumferential annular projection 14 with axial incisions 15.
  • This ring projection 14 which is almost closed with the exception of the mentioned axial incisions, can be snapped into a complementary ring undercut 16 of the pot-like closing element 12. According to FIG. 1, this ring undercut is formed in the interior of the pot-like closing element 12.
  • the pot-like closing element 12 has a centrally projecting pin 17, by means of which the delivery tube 11 can be pushed over almost its entire length such that between the delivery tube 11 and the pin 17 there is a continuous fluid channel 18 between the delivery opening 13 of the delivery tube 11 and its anchoring 19 is defined with the pot-like closing element 12.
  • the anchoring 19 is formed by the aforementioned snap connection between the ring projection 14 and the complementary ring undercut 16.
  • the centrally projecting pin 17 has at least one, in this case three, longitudinal grooves 20 arranged uniformly distributed over the circumference (see FIG. 3c) to form the fluid channel 18 mentioned between pin 17 and dispensing tube 11.
  • the dispensing tube 11 can be pushed without play over the centrally projecting pin 17, so that the dispensing tube with the associated pot-like closing element is movable, in particular tiltable, from the closed position Unit forms.
  • the aforementioned direct power transmission is guaranteed when the dispensing tube is tilted onto the pot-like closing element 12.
  • an elongated, namely sleeve-like extension 22 is connected to the bottom 21 of the pot-like closing element 12, over which extends in the assembled state the helical compression spring mentioned with reference to FIG on the other hand supports and presses the pot-like closing element 12 with its circumferential edge 23 against the ring seal which closely surrounds the dispensing tube 11.
  • the centrally projecting pin has an approximately star-shaped cross section.
  • this cross section can be triangular, square or cross-shaped.
  • the outer edges of the longitudinal webs formed between the longitudinal grooves 20 define an outer diameter which corresponds approximately to the inner diameter of the dispensing tube 11.
  • the peripheral edge 23 of the pot-like closing element 12 is flared outwards, more on the inside than on the outside.
  • the annular undercut 16 is formed on the inside near the bottom 21 of the closing element 12.
  • the pot-like closing element 12 is formed integrally with the centrally projecting pin 17 and the outer sleeve-like extension 22.
  • the extension 22 could in principle also be made from solid material.
