Definitions

  • the invention relates to a self-closing Valve arrangement for installation in a dispensing opening on a Container, a cap or the like.
  • a generic valve arrangement integrated in one Cap is known from DE-A-195 10 007.
  • a membrane-like closing element made of a flexible Material with a central, permanently open Passage between parts of the on a container neck screw-on sealing cap clamped.
  • the In the idle state the closing element is concave and lies with its outside on a sealing element that is held stationary in the cap part to the To close the passage opening.
  • Under an elevated Pressure on the closing element on the part of the sealing element facing surface the closing element from Sealing element are lifted off, so that along the Flow a medium out of a container can, on the neck of which the screw cap is screwed can be.
  • the closing element is clamped in the cap part so that the Clamping effect allows air to pass through when Inside the container there is a vacuum to one To effect pressure equalization.
  • the pressure compensation function hangs thus depending on the type of closure element in the cap part is clamped and can due to the elasticity of the Closing elements and the clamping forces acting on them be impaired, so that the pressure compensation function is not always guaranteed.
  • the channels, along which the ventilation air flows to equalize the pressure can easily clog when in use, and can thereby Pressure compensation function is lost.
  • Another disadvantage is that the sealing of the passage opening in the closing element done by a rigid flat sealing element, so that at Deposits or dirt on the sealing surface Sealing function can be easily affected.
  • JP-A-09 039990 has a self-closing valve arrangement with a Pressure equalization function on which the air from the environment in the Can flow inside the container.
  • the object of the invention is a self-closing Valve arrangement of the generic type with guaranteed Sealing and pressure compensation function at the same time cheaper To create manufacturing opportunities.
  • a self-closing Valve arrangement for installation in a dispensing opening on a Container, a cap or the like, with a first Closing element with a, a passage opening containing wall part made of elastic material that under a first differential pressure force on his opposing surfaces acting pressures elastic is deformable from a closed position into a release position, and a second closing element for sealing the Passage opening when the first closing element is in is in its closed position, according to the invention second locking element under one against the first Differential pressure force directed second differential pressure force from acting on its opposite surfaces Press out of the sealing relationship to the passage opening of the first closing element can be brought.
  • Valve arrangement instead of a rigid second Closing elements such as the first Closing element under the effect of an external one Give up the differential pressure force elastically and thereby from the sealing relationship to the passage opening in the first Closing element can get to for the purpose of Pressure equalization ventilation air from the environment into the Let the inside of the container flow in.
  • Both the first and second closing elements can also be arched like a membrane Include wall parts and made of suitable plastic materials with elastic properties, e.g. an elastomeric material, be educated.
  • the assembly of the locking elements into one self-closing valve arrangement does not prepare Difficulties because the pressure compensation function is not of one mutually positioning the locking elements Clamping force is impaired.
  • the valve arrangement after the Invention can also be easily miniaturized and except in screw caps that can be screwed onto a container neck also insert directly into a donation opening of a container.
  • Fig. 1 is the one bearing the general reference number 1 self-closing valve assembly according to the invention in a wall 3 of a container containing a dispensing opening 4 2 or a closure cap or the like. Shown. Although other means for mounting the valve assembly 1 are provided may be in the present embodiment Container wall 3 concentric with the dispensing opening 4 a Locking flange 5 with a locking collar 6 at its free end formed. Instead of a locking flange, one could A large number of locking bars arranged around the circumference be provided.
  • the between the bottom of the wall 3 and the locking collar 6th Valve arrangement 1 held by clamping force includes a first locking element 7, a second locking element 8 and a support ring 13 resting on the ring collar 6
  • Closing element 7, 8 comprises an outer thickened annular assembly area 9 and 10 and one thereon molded inner membrane-like wall part 11, 12. Die membrane-like wall parts 11, 12 have a in the idle state facing curved configurations, as shown in Fig. 1 is shown.
  • a passage opening 14 is in the membrane-like wall part 11 of the first closing element facing the dispensing opening 4 7 provided.
  • One or more passage openings 15 in the membrane-like wall part 12 of the second closing element 8 create a connection between the top and bottom of the membrane-like wall part 12 at a point which is radial is offset to a central region of the wall part 12.
  • the central area of the wall part 12 is therefore free of Perforations and therefore suitable in that shown in Fig. 1
  • the central passage opening 14 of the first Sealing elements 7 when the tops of the domed Wall parts 11, 12 under a desired biasing force in Stand with each other.
  • the locking elements 7, 8 can be made from a suitable be made of elastic plastic material that stands out Injection molds in the desired configuration can be brought to production. Suitable materials are especially elastomeric materials.
  • the locking elements 7, 8 can be made of the same or different material exist to be the same or different elastic Get properties.
  • Fig. 2 shows the state of the Valve arrangement as it is when on the first Closing element 7 exerts a differential pressure force from below which causes the wall part 11 to separate from the wall part 12 of the second closing element 8, and the Through opening 14 is released.
  • This Condition can be caused by Squeezing the wall of a container into an overpressure is caused.
  • the Wall part 11 of the first closing element 7 due to its Elasticity back to the starting position shown in Fig. 1 sealing the passage opening 14 back.
  • the wall part 12 of the second experiences overpressure in the container Closing elements 8, however, essentially none Shape change because the overpressure is the domed configuration of the Wall part 12 supports.
  • the invention was previously based on an embodiment with arched membrane-like wall parts of the locking elements described.
  • the invention is not based on this limited.
  • an arched one Wall part of the second closing element also one of the acting axially movable central Sealing element for sealing the passage opening in the first closing element can be provided.
  • This Sealing element can e.g. through spoke-like struts the outer thickened assembly area of the second Closing elements to be connected.
  • the support ring on which support the locking elements arranged one above the other not mandatory and can therefore, if desired, be omitted.
  • the thickened Mounting area of the second locking element directly on a Support the collar or a similar part of the container can.
