Definitions

  • the present invention relates to an assembly consisting of a dispensing valve for the delivery of pressurized liquids, foams, gels od. Like. And a fluid-tight connected bag made of flexible film material, according to the preamble of claim 1.
  • Such a structural unit is known from the applicant's EP 0 697 348 B1.
  • the dispensing valve known the shape that a dispensing tube is axially displaceably mounted in the valve body, namely from a closed position against the action of an elastic element, in particular a helical compression spring in a fluid delivery position.
  • an elastic element in particular a helical compression spring in a fluid delivery position.
  • the dispensing tube od of a rubber ring seal.
  • Elastic sealing material tightly enclosed, in such a way that the ring seal closes in the closed position of the dispensing tube or dispensing valve access to a dispensing channel formed in the dispensing tube.
  • a discharge tube is arranged, which is connectable through the bag film and with the interposition of a sealing ring with the valve body of the dispensing valve, in such a way that a fluid connection is obtained between the bag interior and the valve body of the dispensing valve.
  • the discharge tube and / or the valve body are made of unbreakable material and in particular not permeable to organic media material.
  • the dispensing tube has a disk, in particular cylinder-shaped widening, extending around the bag opening mentioned in the bag. As a result, the bag film from the inner Keep the section of the dispensing tube away. This is important both for the filling of the bag and for the delivery of fluid from the bag.
  • the present invention is therefore an object of the invention to eliminate the aforementioned vulnerability of the bag film and the connection thereof with the discharge tube and valve body.
  • the core of the present invention thus lies in an additional reinforcement of the peripheral edge of the bag opening, through which the discharge tube extends, before it is locked in a fluid-tight manner with the valve body.
  • the bag is placed on the widening of the discharge tube with the interposition of an annular disc delimiting the bag opening.
  • the bag opening is thus stabilized by an annular disc, which is preferably welded to the inside of the bag with the bag film.
  • the annular disc also made with the bag film well weldable material, for example polyethylene, polypropylene, polyamide od.
  • the bag film is attached to the pre-welded ring disk on the discharge tube, before then the bag film is welded edge to a fluid-tight bag. It is also conceivable to weld or bond the annular disk with the widening of the discharge tube arranged inside the bag. Regardless of the above-mentioned mounting options, the passage for the discharge tube out of the bag is stabilized by the bag opening limiting annular disk, so that no more cracks occur in case of drop tests at this point. It should also be mentioned at this point that the welding of the bag film with the broadening in the prior art also led to relatively high stresses in the film after filling the bag, which then just vacated in case trials and led to the aforementioned tears.
  • the portion of the dispensing tube extending through the bag opening is preferably latchable into a corresponding opening of the valve body, particularly the bottom thereof, such that the valve body is fluid-tight with the interior of the bag fluid tight with respect to the interior of the outer container is.

  • FIGS. 1 to 4 show a structural unit 10 consisting of a dispensing valve 11 and a bag 12 connected to it in a fluid-tight manner.
  • An outer container 15, which may for example consist of tinplate or plastic, surrounds the bag 12 such that a receiving space between these two components is defined.
  • the container 15 has at its upper end an opening 14 through which the bag 12 is inserted into the container 15 and in the inserted state, the discharge valve 11 projects beyond the container 15.
  • the opening 14 is closed by means of a cover 13 in the usual way.
  • a lid opening 17 is formed.
  • a valve body 18 of the dispensing valve 11 is held by its edge 16 such that a dispensing valve 11 associated dispensing tube 25 passes through the lid opening 17.
  • the dispensing tube 25 can thus be actuated from the outside.
  • Bag 12 and container 15 thus represent a two-chamber package, wherein in the bag 12 (in the present embodiment), a liquid or pasty filling material and in the container 15, a pressure medium, such as air or butane, are filled or filled.
  • a pressure medium such as air or butane
  • the above-mentioned bag and container contents can be filled via the dispensing valve 11 in the bag or in the container.
  • the bag 12 expands in the container 15 and occupies a substantial part of the container volume.
  • the bag contents When emptying the bag is the bag contents with appropriate expansion of the pressure medium in the container 15th auspreßbar via the dispensing valve 11, through the dispensing tube 25 therethrough.
  • the bag 12 is made of a flexible sheet material which is composed of several layers.
  • the film comprises three layers, namely an outer polyamide or polyester layer, a middle aluminum layer and an inner polyethylene or polypropylene layer.
  • the bag 12 extends substantially over the entire length of the interior of the container 15. Concretely, it is formed by a folded over one another and at the edges welded together or sealed film of the type mentioned above.
  • the bag 12 is kept fluid-tight at a portion of the dispensing valve 11.
  • valve body 18 In the valve body 18 is received in the axial direction from a closed to an open position and vice versa displaceably mounted dispensing tube 25, which can be moved against the action of a helical compression spring 26 from a closed position.
  • the helical compression spring 26 is supported on the one hand on a seat in the lower region of the valve body 18 and on the other hand on the delivery tube 25 itself.
  • a ring seal 27 for example made of rubber, which also surrounds the dispensing tube 25 fluid-tight.
  • This ring seal 27 closes the cylindrical and open-topped valve body 18 from above. So it has a double function. First, it prevents material from leaking out of the bag unintentionally over the interior of the valve body; on the other hand, no medium can inadvertently escape from the container interior into the external environment.
  • an access 28 - as shown in particular in FIG. 4 - released by an upper peripheral edge of the valve body 18 on the inside of the ring seal 27 lifts.
  • the valve body 18 has at its - in the illustrated figures - the lower end of a bore 31 which defines an access to the inner cavity of the valve body 18. Through this bore 31, a portion or part of a discharge tube 20 is inserted, which engages in the fully inserted state.
  • the latching effect is achieved in that a radially outwardly projecting annular flange is formed at the discharge valve end of the mentioned tube portion, which engages behind the bore 31 within the valve body 14 in the mounted state.
  • the tube portion 20 has been inserted through an opening of the bag film before insertion into the bore 31 of the valve body 18, so that the bag 12 is clamped with the interposition of a further sealing ring 24 between the discharge tube 20 and the valve body 18.
