Definitions

  • the invention relates to a valve insert for a two-chamber compressed gas pack for the separate storage of two product components in an inner and an outer container and for mixing the product components, with a cover having a removal tube in a central through opening for closing an opening of the outer container, which is smaller than the diameter of the outer container, with an elastic ring seal sealing the extraction tube against the through-opening, in which the extraction tube is axially displaceable from an outer to an inner end position for piercing a wall of the inner container, and manually to release the mixture removal Actuatable valve, wherein the extraction tube is closed at the end facing the inner container, so that the valve is closed in the intermediate position, and wherein the lid on the inside of a surrounding the extraction tube and passage openings for d he product component coupling for coupling the inner container to the lid.
  • the invention has for its object to provide a valve insert of the generic type, in which it is ensured that the removal is not possible before the product components are mixed.
  • this object is achieved in that the valve is moved into the inner end position by moving the extraction tube from the outer end position, in which the valve is closed, to an intermediate position, in which the wall of the inner container penetrates and the valve is still closed. in which the valve is open, can be actuated.
  • the ring seal can then be an annular disk held between the inside of the cover and the end of the coupling connected to the cover, and the removal tube can be guided axially displaceably in the coupling.
  • the extraction tube is closed at the end facing the inner container and has a radial valve opening which cooperates with the annular disc as a valve and which, in the intermediate position of the extraction tube, lies near the inside of the annular disc.
  • the ring seal also acts as a valve closure piece, so that a valve tappet is not required.
  • the removal tube can then have a cutting disc at the inner end with at least one cutting edge facing the inner container on the peripheral edge.
  • the cutting disc results in an immediate formation of a larger hole in the wall of the inner container facing it, through which the contents of the inner container, through which the contents of the inner container can escape quickly and can mix with the contents of the outer container as soon as the sampling tube has reached the intermediate position.
  • the extraction tube can be made correspondingly shorter than in the generic valve insert, in which the inner end section of the extraction tube is surrounded by an annular disc at a distance from the inner end of the extraction tube to widen the opening formed by this end in the inner container.
  • a further development can then consist in the coupling having a first coupling part which can be brought into engagement with the inner container and a second coupling part which is in engagement with the cover, which are axially fixedly connected, and in that the inside of the first coupling part has an undercut, on which a corresponding undercut on the circumference of the sampling tube is placed under the pressure of a return spring acting in the direction of the outer end position in the intermediate position.
  • This configuration ensures that the sampling tube cannot be returned to the outer end position after the inner container has been pierced.
  • the first coupling part has approximately the shape of a hood which positively engages over the inner container and has passage openings in the bottom which at the same time forms a bottom of the second coupling part on which the return spring is supported.
  • This type of connection e.g. B. a snap connection or screw connection between the first coupling part and the inner container allows easy assembly, for. B. automatically, and still causes a solid cohesion of both parts. Nevertheless, the contents of the inner container can pass freely through the passage opening after it has pierced its wall through the hood to mix it with the contents of the first container. At the same time, the bottom of the hood has a supporting function for the return spring.
  • the coupling parts can be manufactured separately and held together by a plug connection. This enables a simple production of the coupling from plastic plastic in a mold while avoiding demolding difficulties.
  • the second coupling part to the first coupling part can have axially continuous slots as through openings and engage under radial spring preload in an annular groove of the first coupling part.
  • the coupling parts can be easily connected to one another by plugging them together. Nevertheless, they are securely connected axially by a high frictional force.
  • the axially continuous slots lead on the one hand to a spring action of the finger-like webs remaining between them and on the other hand allow the product components to pass through.
  • the cutting disk can also have passage openings which radially overlap passage openings formed on both sides of the annular groove in the bottom of the first coupling part. This ensures a largely unhindered escape of the contents of the inner container after it has been opened.
  • an actuating cap can be attached to the outside of the lid with its opening edge so that the edge of a central outlet opening in a central actuating part of the actuating cap is seated on the outer open end of the extraction tube, and that the actuating part on the outer part of the Actuating cap is articulated.
  • This actuating cap allows the valve to be opened easily by pivoting the actuating part by means of the thumb or a finger of the same hand with which the compressed gas pack is held.
  • a protective hood covering the actuating cap firmly surrounds the peripheral wall of the actuating cap by means of a tear-off opening edge section, the axial length of which corresponds to the stroke of the extraction tube from the outside End position corresponds to the intermediate position, and when the protective hood is supported on the actuating part.
  • a pressure for. B. a blow to the protective cover this only by the mentioned stroke and thus the sampling tube from the end position inevitably initially only to the intermediate position in which the inner container is pushed open but the valve is not yet open.
  • the outlet opening can be formed in the bottom of a recess on the inside of the actuating part which swivels over the outer end of the removal tube.
  • the depression on the one hand ensures centering of the actuating part relative to the extraction tube, and vice versa, and on the other hand enables the actuating part to be pivoted while axially displacing the extraction tube without tilting the extraction tube itself.
  • the recess rotatably engages over the outer end of the sampling tube, that the actuating part has two sections which extend diametrically with respect to its axis of rotation, one section of which has an axial thickness greater than the mentioned stroke than the other Has section, the thickness of which is smaller than the axial stroke, and that the opening in the bottom of the actuating cap on the side of that section extends over a larger angle of rotation range of the actuating part than this section.
  • the actuating part after being brought into the intermediate position by sliding the hood to tear its connection with the outer part of the actuating cap, the actuating part can be rotated relative to the outer part of the actuating cap so that one section of the actuating cap is rotated, so that one section of the actuating part continues to protrude axially outward beyond the outer part of the actuating cap, whereas the other section of the actuating part rests articulated under this outer part of the actuating cap.
  • the actuating part is therefore no longer connected to the actuating cap, it is nevertheless pivotally mounted only against the pressure of the return spring in order to bring about the opening of the valve by axially displacing the extraction tube.
  • the circumference of the coupling end section facing the cover can then be provided with axial ribs, which are bordered by an edge section of the central through-opening of the cover, which takes up the play tube with play, leaving axial passage channels free, and the end face of the coupling end, which is designed as an annular disk, faces radially backward beveled outside.
  • This design allows easy filling of the outer container with compressed gas by attaching the filling head of a conventional filling device, the elastic ring disc being compressed at its outer peripheral edge and opening up an inlet channel for the compressed gas.
  • the two-chamber compressed gas pack consists of an outer container 1, an inner container 2 arranged in the outer container 1 and a valve insert 3.

In the middle, the cover 7 is provided with a through opening 17 through which the removal tube 6 is guided with play.
  • the coupling 8 has a first coupling part 18 which can be brought into engagement with the inner container 2 and a coupling part 19 which engages with the cover 7.
  • the coupling part 18 has at the inner end a hood 20, which is interrupted several times in a segment-like manner by axial slots in the side wall and consists of a plurality of elastic holding claws 21 with an undercut, as a holder for receiving the container 2, the opening edge of which has a radially projecting annular flange 22 which engages behind the undercut.
  • the connection of container 2 and coupling part 18 can also be designed as a bayonet lock.
