Definitions
- the invention relates to a two-chamber pack according to the preamble of patent claim 1.
- Such a two-chamber package is known from US-A 3 317 090.
- it is proposed to design the lower or bottom portion of the inner bag to be slightly larger than the remaining part of the inner bag, in order to ensure that the inner bag expands progressively from the bottom of the outer container to the dispensing valve after being filled with compressed gas.
- this requirement cannot be guaranteed by the known design of the inner bag.
- An expansion in the middle or upper area of the inner bag is entirely possible, depending on the random initial resistance of the filling material - especially with pasty filling material - on the inner bag when it is filled with compressed gas.
- the present invention has for its object to provide a two-chamber pack of the type mentioned, which ensures complete emptying, regardless of the type of product.
- the two-chamber pack according to the invention is characterized in that the inner bag is formed by a film which is folded over one another and welded or sealed to one another along the longitudinal edge, the bottom being folded such that an essentially flat bag bottom is formed when the inner bag is filled with compressed gas, which extends over the bottom of the container.
- the bottom folding according to the invention ensures that when the inner bag is filled with compressed gas, the bottom of the inner bag first unfolds, so that when the two-chamber pack is emptied, expansion of the inner bag is inevitable from the bottom to the dispensing valve. This prevents material inclusions and thus incomplete emptying of the package.
- the space delimited by the filling material on the one hand and the walls of the outer container and inner bag on the other hand should be largely evacuated, so that after filling the inner bag with compressed gas, the filling material is at the dispensing valve.
- the formation of an air cushion which interferes with the dispensing of the filling material is avoided in the region of the part of the dispensing valve inside the container or before access to the dispensing rack.
- the evacuation is preferably carried out before the container lid is crimped on.
- the design of the dispensing valve according to claims 8 ff. enable the double function set out above.
- the dispensing valve in a very simple and reliable manner.
- the elastic element in the form of a helical compression spring urging the dispensing tube into the closed position has a double function, namely, on the one hand to urge the dispensing tube into the closed position and, on the other hand, to close the stopper for the filling opening that opens into the inner bag in the closed position hold.
- the closing plug which is displaceably arranged within the valve body of the dispensing valve, also has a double function, namely on the one hand to close the filling opening which opens into the inner bag for the gassing thereof, and on the other hand the fluid connection between the interior of the outer container and the dispensing valve during the gassing of the inner bag or to interrupt the delivery tube.
- the latter concept in particular is crucial for the dual function of the dispensing valve.
- Pasty materials such as ketchup, cream, mayonnaise, skin cream or the like, or liquid substances, such as hair colorants, eau de cologne or the like, are suitable as filling material.
- the two-chamber pack according to the invention is assembled in such a way that the contents are first filled into the outer container. Subsequently, the inner bag, rolled up or folded in the longitudinal direction, is inserted through the upper container opening into the outer container, whereby to stabilize or increase the stiffness of the inner bag, the inner bag is provided with a riser tube which is connected to the filling opening of the valve body opening into the inner bag is. The inner bag is already connected to the dispensing valve during this process.
- the container lid is then crimped onto the opening edge of the outer container in a manner known per se with simultaneous evacuation of the space between the outer container, inner bag and lid, so that when the inner bag is fumigated, the filling material goes up to the dispensing valve without any training can evade a larger air cushion.
- This ensures that when the two-chamber pack is used for the first time, not only does air escape, but the filling material immediately in the desired dosage.
- the filling material should therefore "stand” at the discharge opening before the first use of the two-chamber pack.
- a discharge or spray head is mounted in a manner known per se. Since this is a component known per se, a detailed description of the same is unnecessary here.
- the inner bag is gassed through the dispensing valve or dispensing tube. After this process has been completed, the dispensing tube is pressed further into the interior of the container while simultaneously moving the above-mentioned closing plug into the filling opening-closing position.
- the inner bag filled with compressed gas is hermetically sealed from the environment. The two-chamber pack is ready for use.
- the inner bag filled with compressed gas preferably fills approximately 1/3 of the interior of the outer container.
- the pressure gas filled is under a pressure of about 9 bar.
- 2/3 of the interior of the outer container is filled with filling material. Then it is ensured that the filling material is discharged with a constant pressure of about 3 bar until it is completely emptied.
- the two-chamber pack shown schematically in FIGS. 1 and 2 comprises an essentially dimensionally stable, for example made of tinplate, provided with a dispensing valve 2 outer container 1 for a liquid or pasty filling material and an inner container arranged in the outer container 1 in the form of a flexible bag 3 for receiving compressed gas, such as compressed air, nitrogen or the like.
- compressed gas such as compressed air, nitrogen or the like.
- the dispensing valve 2 has a valve body 14 from a closed to an open position and vice versa movably mounted, namely axially displaceable delivery tube 17.
- the inner bag 3 which is made of a multi-layer plastic film with an aluminum lamination on the outside, is connected to the dispensing valve 2 and can be filled therewith after filling the outer container 1 with filling material and closing it with compressed gas, so that when the dispensing valve 2 is open, the filling material is expanded accordingly of the inner bag 3 can be squeezed out of the outer container 1, specifically through the delivery tube 17 already mentioned.
- the inner bag 3 extends, as can be seen in FIGS. 1 and 2, essentially over the entire length of the interior of the outer container 1 and is cut and folded in such a way that it essentially completely fills the interior of the outer container 1 Hose expands, as can be seen in FIG. 2, progressively from the bottom 4 of the outer container 1 to the dispensing valve 2.
- the inner bag 3 is formed by a multilayer film of the above-mentioned type which is folded over one another, welded or sealed at the edges, the bottom being folded such that when the inner bag 3 is filled with compressed gas, an essentially flat bag bottom 5 is formed, which is formed extends over the container bottom 4. This is to ensure that as little residual filling material as possible remains in the bottom region of the outer container 1 and that the container 1 is emptied essentially completely starting from the bottom 4.
- the formation of a flat bag bottom 5 can be achieved, for example, by folding the bottom of the inner liner 3 in such a way that it comprises an inward V-fold 6 which extends transversely between the two diametrical longitudinal sealing edges 7 and 8 of the inner bag 3.
- the V-fold 6, in continuation of the two longitudinal sealing edges 7 and 8, is delimited by sealing edges 9, 10 and 11, 12 directed obliquely inwards. 2 are the Sealing edges 11, 12 are each not visible behind the sealing edges 9 or 10.
- the additional extends Seal connection 13 from the upper or the discharge valve 2 facing end of the inner bag 3 over about 2/3 of the total length of the inner bag 3, the additional seal connection 13 being formed by two sealing strips extending parallel to one another and at a distance from one another.
- the sealing strips can also be interrupted, in particular only be effective at certain points.
- the strength of the additional sealing connection 13 in the direction of the dispensing valve 2 is preferably increasingly greater, as a result of which the targeted progressive expansion of the inner bag is promoted from the bottom upwards.
- a spray head 28 with a spray nozzle 29 is also arranged. This component is a generally known construction element, the detailed description of which is therefore not necessary.
- the valve body 14 of the dispensing valve 2 extends - sealed off from the interior of the outer container - into the inner bag 3, specifically in the area of the upper or the dispensing valve 2 facing edge sealing seam 15, the edge sealing seam 15 enclosing the valve body 14 on the outside in a fluid-tight manner.
- the valve body 14 has a filling opening 16 opening into the interior of the inner bag 3, through which the inner bag 3 is fumigated and which, after fumigation or filling of the inner bag 3 with compressed gas, through the dispensing valve 2 or the latter Dispensing tube 17 can be closed by means of a closing plug 18.
- the closing plug 18 is designed so that in the starting position, ie in a position for filling the inner bag 3 with compressed gas, as shown in FIGS. 3 to 6, a passage opening connecting the interior of the outer container 1 with the interior of the valve body 14 20 closes, so that the fluid connection between the interior of the outer container 1 and the axially displaceably mounted in the valve body 14 dispensing tube 17 of the dispensing valve 2 is interrupted during the gassing or filling of the inner bag 3 with compressed gas.
- An axially effective elastic element in particular a helical compression spring 19, is arranged between the closing plug 18 and the dispensing tube 17, against the action of which the dispensing tube 17 can be axially pressed into the valve body 14 with the release of a fluid connection to the outside, the closing plug 18 for filling the inner bag 3 with compressed gas inside the valve body 14 in a starting position raised from the filling opening 16 opening into the inner bag 3, in which the compressed gas can be introduced into the inner bag 3 through the dispensing tube 17 pressed axially into the valve body 14 and past the closing plug 18 on the outside ( see flow arrows 30 in FIGS. 4 and 5). After filling the inner bag 3 with compressed gas, the closing plug 18 is moved according to FIG.
- the closing plug 18 is made of a harder material, in particular plastic material, such as rigid PVC, than the valve body 14.
- the closing plug 18 comprises a pot-like guide sleeve 25 on the side facing the dispensing tube 17, into which the inside of the container is located facing part of the helical compression spring 19 and its outer peripheral edge 26 facing the delivery tube 17 protrudes radially outwards with sharp edges in order to support the inside of the peripheral wall 27 which laterally delimits the valve body 14 to move the closing plug 18 out of the filling opening-closed position according to FIG. 7 to complicate.
- the closing plug 18 is accordingly held both by the helical compression spring 19, the sharp-edged peripheral edge 26 and the radially inwardly projecting latching projection 24, which interacts with the radially outwardly extending annular projection 23 of the closing plug 18.
- the pot-like closing plug 18 is held in a position raised from the filling opening 16, specifically by locking means 22, 23 in the form of radially projecting circumferential ribs on the inside of the cylinder wall 27 laterally delimiting the valve body 14 on the one hand and on the Outside of the guide sleeve 25 on the other hand. Between these two radially projecting circumferential ribs are formed through openings 33, which are evenly distributed over the circumference and through which the compressed gas flows into the inner bag 3 (arrow 30 in FIG. 5).
- the axial movement of the dispensing tube 17 takes place through a filling head, not shown.
- the dispensing valve 2 or its valve body 14 is anchored centrally to the container lid 34 in a manner known per se. For this reason, a more detailed description of this mounting structure is not required.
- FIG. 7 shows the dispensing tube 17 with the filling opening 16 closed in the filling material discharge position.
- the filling material can flow out according to the arrows 35 through the openings 20, the interior of the valve body 14 and the fluid channel 36 of the dispensing valve 17, namely under the action of the expanding inner bag 3.
- the dispensing valve 2 is in the closed position after filling the outer container 1 and fumigation of the inner bag 3rd
- this riser serves essentially only to increase the kink stability of the inner bag 3, so that it can be more easily immersed in the container 1 filled with the filling material, especially if the filling material is a pasty mass.
- FIG. 9 shows an alternative construction of the dispensing valve in relation to the closing plug 18.
- Parts of the dispensing valve 2 already described with reference to the preceding figures are identified in FIG. 9 with the same reference numbers. With regard to their function, reference is therefore made to the preliminary description.
- the special feature of the embodiment according to FIG. 9 is that the guide sleeve 25 is tight over the entire circumference on the inside of the valve body 14 laterally bounding peripheral wall 27 abuts.
- through openings 21 are arranged in the bottom of the pot-shaped guide sleeve 25, through which the inner bag 3 is fumigated when the stopper 18 is lifted from the filling opening 16 (see arrows 30).
- the locking means assigned to the closing plug 18, which hold it in the position raised from the filling opening 16 during the gassing of the inner bag 13, have also been changed compared to the previously described embodiment.
- the locking means 24 assigned to the valve body 14 are formed by a clamping sleeve which is arranged in the interior of the valve body around the filling opening 16, in particular molded on, while the locking means 22 assigned to the closing plug 18 are formed by a plurality of radial ribs which are arranged evenly distributed over the circumference and which coincide with them Support the inner end of the container on the peripheral edge of the clamping sleeve facing the dispensing tube 17 during the gassing of the inner bag 3, as a result of which the closing plug 18 is held in a position lifted from the filling opening 16 in accordance with FIG.
- the dispensing tube 17 is pressed even further into the container by the filling head (not shown), bearing against the projection 32 described above.
- the radial ribs 22 are pressed into the clamping sleeve 24, so that the closing plug 18, which is likewise pressed into the filling opening 16, is held in the filling opening-closed position.
- the closing plug 18 is held in this position by the action of the compression spring 19 and the sharp-edged circumferential edge 26, which really grips the inside of the peripheral wall 27 that laterally delimits the valve body 14.
- the inner bag 3 is thus permanently sealed in a fluid-tight manner after fumigation. All other parts of the delivery valve 2 shown in FIG. 9 are the same as those of the delivery valve described above, so that - as already explained above - a more detailed description of these parts is unnecessary at this point.

Abstract
Description
Die Erfindung betrifft eine Zweikammerpackung gemäß Oberbegriff des Patentanspruches 1.The invention relates to a two-chamber pack according to the preamble of patent claim 1.
Eine derartige Zweikammerpackung ist aus der US-A 3 317 090 bekannt. Bei der bekannten Zweikammerpackung ist vorgeschlagen, den unteren bzw. bodenseitigen Abschnitt des Innenbeutels geringfügig größer auszubilden als den übrigen Teil des Innenbeutels, um sicherzustellen, daß der Innenbeutel nach Befüllung mit Druckgas fortschreitend vom Boden des äußeres Behälters zum Abgabeventil hin expandiert. Durch die bekannte Ausbildung des Innenbeutels kann diese Voraussetzung jedoch nicht gewährleistet werden. Eine Expansion im mittleren oder oberen Bereich des Innenbeutels liegt durchaus im Bereich des Möglichen, und zwar anhängig vom zufälligen Anfangswiderstand des Füllguts - insbesondere bei pastösem Füllgut - auf den Innenbeutel bei Befüllung desselben mit Druckgas.Such a two-chamber package is known from US-A 3 317 090. In the known two-chamber pack, it is proposed to design the lower or bottom portion of the inner bag to be slightly larger than the remaining part of the inner bag, in order to ensure that the inner bag expands progressively from the bottom of the outer container to the dispensing valve after being filled with compressed gas. However, this requirement cannot be guaranteed by the known design of the inner bag. An expansion in the middle or upper area of the inner bag is entirely possible, depending on the random initial resistance of the filling material - especially with pasty filling material - on the inner bag when it is filled with compressed gas.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Zweikammerpackung der eingangs genannten Art zu schaffen, die eine vollständige Entleerung gewährleistet, und zwar unabhängig von der Art des Füllguts.The present invention has for its object to provide a two-chamber pack of the type mentioned, which ensures complete emptying, regardless of the type of product.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Dementsprechend zeichnet sich die erfindungsgemäße Zweikammerpackung dadurch aus, daß der Innenbeutel durch eine übereinander gefaltete, längsrandseitig miteinander verschweißte bzw. versiegelte Folie gebildet ist, wobei die Faltung bodenseitig derart vorgenommen ist, daß sich bei Befüllung des Innenbeutels mit Druckgas ein im wesentlichen flacher Beutelboden ausbildet, der sich über den Behälterboden erstreckt. Durch die erfindungsgemäße Bodenfaltung ist gewährleistet, daß bei Befüllung des Innenbeutels mit Druckgas sich zunächst der Boden des Innenbeutels auffaltet, so daß bei Entleerung der Zweikammerpackung zwangsläufig eine Expansion des Innenbeutels ausgehend vom Boden zum Abgabeventil erfolgt. Materialeinschlüsse und damit eine unvollständige Entleerung der Packung sind auf diese Weise ausgeschlossen.This object is achieved by the characterizing features of claim 1. Accordingly, the two-chamber pack according to the invention is characterized in that the inner bag is formed by a film which is folded over one another and welded or sealed to one another along the longitudinal edge, the bottom being folded such that an essentially flat bag bottom is formed when the inner bag is filled with compressed gas, which extends over the bottom of the container. The bottom folding according to the invention ensures that when the inner bag is filled with compressed gas, the bottom of the inner bag first unfolds, so that when the two-chamber pack is emptied, expansion of the inner bag is inevitable from the bottom to the dispensing valve. This prevents material inclusions and thus incomplete emptying of the package.
In den Unteransprüchen sind vorteilhafte Weiterbildungen der erfindungsgemäßen Zweikammerpackung beschrieben. Dies gilt insbesondere für die besondere Gestaltung der Bodenfaltung des Innenbeutels nach den Ansprüchen 3 und 4. Zu den Maßnahmen nach den Ansprüchen 5 und 6 sei noch erwähnt, daß die Festigkeit der dort vorgeschlagenen Zusatz-Versiegelung ausgehend vom Abgabeventil in Richtung zum Boden des Innenbeutels abnimmt, wodurch die gewünschte kontrollierte fortschreitende Expansion des Innenbeutels von unten nach oben zusätzlich unterstützt wird.Advantageous developments of the two-chamber pack according to the invention are described in the subclaims. This applies in particular to the special design of the bottom fold of the inner bag according to
Gemäß Anspruch 2 soll der durch das Füllgut einerseits und die Wände des äußeren Behälters sowie Innenbeutels andererseits begrenzte Freiraum weitgehend evakuiert sein, so daß nach Befüllung des Innenbeutels mit Druckgas das Füllgut am Abgabeventil steht. Auf diese Weise wird die Ausbildung eines die Abgabe des Füllguts beeinträchtigenden Luftpolsters im Bereich des behälterinneren Teils des Abgabeventils bzw. vor dem Zugang zum Abgaberechen vermieden. Die Evakuierung erfolgt vorzugsweise vor dem Aufkrimpen des Behälterdeckels.According to
Des weiteren ist von besonderer Bedeutung, und zwar unabhängig von der vorbeschriebenen Konstruktion, die Ausbildung des Abgabeventils nach den Ansprüchen 8 ff. Die dort beschriebenen Merkmale ermöglichen die oben dargelegte Doppelfunktion.
des Abgabeventils in denkbar einfacher wie funktionssicherer Weise. In diesem Zusammenhang sei auch erwähnt, daß das das Abgaberöhrchen in Schließstellung drängende elastische Element in Form einer Schraubendurckfeder eine Doppelfunktion hat, nämlich zum einen das Abgaberöhrchen in Schließstellung zu drängen, und zum anderen, den Schließpfropfen für die in den Innenbeutel mündende Füllöffnung in Schließstellung zu halten. Auch der innerhalb des Ventilkörpers des Abgabeventils verschiebbar angeordnete Schließpfropfen weist eine Doppelfunktion auf, nämlich zum einen die in den Innenbeutel mündende Füllöffnung für die Begasung desselben zu verschließen, und zum anderen während der Begasung des Innenbeutels die Fluidverbindung zwischen dem Innenraum des äußeren Behälters und dem Abgabeventil bzw. dem Abgaberöhrchen zu unterbrechen. Vor allem das letztgenannte Konzept ist ausschlaggebend für die Doppelfunktion des Abgabeventils.Furthermore, it is of particular importance, regardless of the construction described above, the design of the dispensing valve according to
the dispensing valve in a very simple and reliable manner. In this context, it should also be mentioned that the elastic element in the form of a helical compression spring urging the dispensing tube into the closed position has a double function, namely, on the one hand to urge the dispensing tube into the closed position and, on the other hand, to close the stopper for the filling opening that opens into the inner bag in the closed position hold. The closing plug, which is displaceably arranged within the valve body of the dispensing valve, also has a double function, namely on the one hand to close the filling opening which opens into the inner bag for the gassing thereof, and on the other hand the fluid connection between the interior of the outer container and the dispensing valve during the gassing of the inner bag or to interrupt the delivery tube. The latter concept in particular is crucial for the dual function of the dispensing valve.
Als Füllgut kommen in Frage pastöse Massen, wie Ketchup, Sahne, Mayonnaise, Hautcreme oder dergl. oder flüssige Stoffe wie Haarfärbemittel, Eau de Cologne oder dergl.Pasty materials, such as ketchup, cream, mayonnaise, skin cream or the like, or liquid substances, such as hair colorants, eau de cologne or the like, are suitable as filling material.
Die Montage der erfindungsgemäßen Zweikammerpackung erfolgt derart, daß zunächst in den äußeren Behälter das Füllgut eingefüllt wird. Anschließend wird der Innenbeutel, zusammengerollt oder in Längsrichtung zusammengefaltet, durch die obere Behälteröffnung hindurch in den äußeren Behälter eingeführt, wobei zur Stabilisierung bzw. Erhöhung der Knicksteifigkeit des Innenbeutels dieser mit einem Steigröhrchen versehen ist, welches an die in den Innenbeutel mündende Füllöffnung des Ventilkörpers angeschlossen ist. Der Innenbeutel ist bei diesem Vorgang bereits mit dem Abgabeventil verbunden. Anschließend wird der Behälterdeckel in an sich bekannter Weise auf den Öffnungsrand des äußeren Behälters aufgekrimpt unter gleichzeitiger Evakuierung des Freiraums zwischen äußerem Behälter, Innenbeutel und Deckel, so daß bei Begasung des Innenbeutels das Füllgut nach oben zum Abgabeventil ohne Ausbildung eines größeren Luftpolsters ausweichen kann. Damit ist gewährleistet, daß beim ersten Gebrauch der Zweikammerpackung zunächst nicht nur Luft entweicht, sondern unmittelbar das Füllgut in der gewünschten Dosierung. Das Füllgut soll also vor dem ersten Gebrauch der Zweikammerpackung an der Abgabe-öffnung "stehen". Am freien Ende des Abgaberöhrchens ist in an sich bekannter Weise ein Austrags- oder Sprühkopf montiert. Da es sich dabei um ein an sich bekanntes Bauelement handelt, erübrigt sich hier eine nähere Beschreibung desselben.The two-chamber pack according to the invention is assembled in such a way that the contents are first filled into the outer container. Subsequently, the inner bag, rolled up or folded in the longitudinal direction, is inserted through the upper container opening into the outer container, whereby to stabilize or increase the stiffness of the inner bag, the inner bag is provided with a riser tube which is connected to the filling opening of the valve body opening into the inner bag is. The inner bag is already connected to the dispensing valve during this process. The container lid is then crimped onto the opening edge of the outer container in a manner known per se with simultaneous evacuation of the space between the outer container, inner bag and lid, so that when the inner bag is fumigated, the filling material goes up to the dispensing valve without any training can evade a larger air cushion. This ensures that when the two-chamber pack is used for the first time, not only does air escape, but the filling material immediately in the desired dosage. The filling material should therefore "stand" at the discharge opening before the first use of the two-chamber pack. At the free end of the dispensing tube, a discharge or spray head is mounted in a manner known per se. Since this is a component known per se, a detailed description of the same is unnecessary here.
Dann erfolgt durch das Abgabeventil bzw. Abgaberöhrchen desselben hindurch die Begasung des Innenbeutels. Nach Beendigung dieses Vorgangs wird das Abgaberöhrchen noch weiter in das Behälterinnere gedrückt unter gleichzeitiger Bewegung des oben erwähnten Schließpfropfens in die Füllöffnung- Schließstellung. Damit ist der mit Druckgas gefüllte Innenbeutel hermetisch gegenüber der Umgebung abgeschlossen. Die Zweikammerpackung ist funktionsbereit.Then the inner bag is gassed through the dispensing valve or dispensing tube. After this process has been completed, the dispensing tube is pressed further into the interior of the container while simultaneously moving the above-mentioned closing plug into the filling opening-closing position. The inner bag filled with compressed gas is hermetically sealed from the environment. The two-chamber pack is ready for use.
Vorzugsweise füllt der mit Druckgas gefüllte Innenbeutel etwa 1/3 des Innenraums des äußeren Behälters aus. Das eingefüllte Druckgas steht unter einem Druck von etwa 9 bar. 2/3 des Innenraums des äußeren Behälters ist mit Füllgut gefüllt. Dann ist gewährleistet, daß das Füllgut bis zur vollständigen Entleerung mit einem konstanten Druck von etwa 3 bar ausgetragen wird.The inner bag filled with compressed gas preferably fills approximately 1/3 of the interior of the outer container. The pressure gas filled is under a pressure of about 9 bar. 2/3 of the interior of the outer container is filled with filling material. Then it is ensured that the filling material is discharged with a constant pressure of about 3 bar until it is completely emptied.

Die in den Fig. 1 und 2 schematisch dargestellte Zweikammerpackung umfaßt eines im wesentlichen formstabilen, z.B. aus Weißblech hergestellten, mit einem Abgabeventil 2 versehenen äußeren Behälter 1 für ein flüssiges oder pastöses Füllgut sowie einen im äußeren Behälter 1 angeordneten inneren Behälter in Form eines flexiblen Beutels 3 zur Aufnahme von Druckgas, wie Druckluft, Stickstoff oder dergl. umweltverträglichem Gas. Das Abgabeventil 2 weist ein in einem Ventilkörper 14 aus einer Schließ- in eine Offenstellung und umgekehrt bewegbar gelagertes, nämlich axial verschiebbares Abgaberöhrchen 17 auf. Der Innenbeutel 3, der aus einer mehrlagigen Kunststoffolie mit außenseitiger Aluminiumkaschierung hergestellt ist, ist mit dem Abgabeventil 2 verbunden und über dieses nach Befüllung des äußeren Behälters 1 mit Füllgut und Verschließen desselben mit Druckgas befüllbar, so daß bei geöffnetem Abgabeventil 2 das Füllgut unter entsptechender Expansion des Innenbeutels 3 aus dem äußeren Behälter 1 auspreßbar ist, und zwar durch das bereits erwähnte Abgaberöhrchen 17 hindurch. Der Innenbeutel 3 erstreckt sich, wie die Fig. 1 und 2 erkennen lassen, im wesentlichen über die gesamte Länge des Innenraums des äußeren Behälters 1 und ist derart geschnitten sowie gefaltet, daß er unter Ausbildung eines den Innenraum des äußeren Behälters 1 im wesentlichen vollständig ausfüllenden Schlauchs expandiert, und zwar - wie Fig. 2 erkennen läßt - fortschreitend vom Boden 4 des äußeren Behälters 1 zum Abgabeventil 2 hin. Konkret ist der Innenbeutel 3 durch eine übereinandergefaltete, randseitig miteinander verschweißte bzw. versiegelte mehrlagige Folie der oben genannten Art gebildet, wobei die Faltung bodenseitig derart vorgenommen ist, daß sich bei Befüllung des Innenbeutels 3 mit Druckgas ein im wesentlichen flacher Beutelboden 5 ausbildet, der sich über den Behälterboden 4 erstreckt. Damit soll sichergestellt sein, daß möglichst wenig Rest-Füllgut im Bodenbereich des äußeren Behälters 1 verbleibt und daß der Behälter 1 im wesentlichen vollständig ausgehend vom Boden 4 entleert wird. Die Ausbildung eines flachen Beutelbodens 5 läßt sich z.B. erreichen durch eine Bodenfaltung des Innenneutels 3 derart, daß sie eine nach innen gerichtete V-Falte 6 umfaßt, die sich quer zwischen den beiden diametralen Längssiegelrändern 7 und 8 des Innenbeutels 3 erstreckt. An ihren diametralen Enden ist die V-Falte 6 in Fortsetzung der beiden Längssiegelränder 7 und 8 durch schräg nach innen gerichtete Siegelränder 9, 10 bzw. 11, 12 begrenzt. In Fig. 2 liegen die Siegelränder 11, 12 jeweils nicht sichtbar hinter den Siegelrändern 9 bzw. 10.The two-chamber pack shown schematically in FIGS. 1 and 2 comprises an essentially dimensionally stable, for example made of tinplate, provided with a dispensing
Um die erwähnte fortschreitende Expansion des Innenbeutels 3 von unten nach oben unter entsprechendem Austrag des Füllguts durch das Abgabeventil 2 hindurch in kontrollierter Weise sicherzustellen, sind die zur Ausbildung des Innenbeutels 3 übereinander gefalteten Folienabschnitte ausgehend vom oberen bzw. dem Abgabeventil 2 zugewandten ende in Richtung zum bodenseitigen Ende hin im Bereich zwischen den beiden Längssiegelrändern 7 und 8 miteinander versiegelt, wobei diese Zusatz-Siegelverbindung 13 merklich schwächer, insbesondere um etwa 40 bis 50 % schwächer ausgebildet ist als die Längsrandsiegelung 7 bzw. 8. Entsprechend Fig. 1 erstreckt sich die Zusatz-Siegelverbindung 13 vom oberen bzw. dem Abgabeventil 2 zugewandten Ende des Innenbeutels 3 her über etwa 2/3 der Gesamtlänge des Innenbeutels 3, wobei die Zusatz- Siegelverbindung 13 durch zwei sich parallel zueinander und im Abstand voneinander erstreckende Siegelstreifen gebildet ist. Die Siegelstreifen können auch unterbrochen, insbesondere nur punktuell wirksam ausgebildet sein. Vorzugsweise ist die Festigkeit der Zusatz-Siegelverbindung 13 in Richtung zum Abgabeventil 2 hin zunehmend größer, wodurch die gezielte fortschreitende Expansion des Innenbeutels von unten nach oben gefördert wird. Am aus dem äußeren Behälter 1 herausragenden freien Ende des Abgaberöhrchens 17 ist noch ein Sprühkopf 28 mit Sprühdüse 29 angeordnet. Bei diesem Bauteil handelt es sich um ein allgemein bekanntes Konstruktionselment, dessen nähere Beschreibung daher nicht erforderlich ist.In order to ensure the above-mentioned progressive expansion of the
Unter Bezugnahme auf die Fig. 3 bis 8 sei nun das speziell angepaßte Abgabeventil näher beschrieben. Der Ventilkörper 14 des Abgabeventils 2 erstreckt sich - gegenüber dem Innenraum des äußeren Behälters abgedichtet - in den Innenbeutel 3 hinein, und zwar im Bereich des oberen bzw. dem Abgabeventil 2 zugewandten Randsiegelnaht 15, wobei die Randsiegelnaht 15 den Ventilkörper 14 außenseitig fluiddicht umschließt. Am unteren bzw. behälterinnenseitigen Ende weist der Ventilkörper 14 eine in das Innere des Innenbeutels 3 mündende Füllöffnung 16 auf, durch die hindurch die Begasung des Innenbeutels 3 erfolgt und die nach Begasung bzw. Befüllung des Innenbeutels 3 mit Druckgas durch das Abgabeventil 2 bzw. dessen Abgaberöhrchen 17 hindurch mittels eines Schließpfropfens 18 verschließbar ist. Der Schließpfropfen 18 ist so ausgebildet, daß er in Ausgangsstellung, d.h. in einer Stellung zum Befüllen des Innenbeutels 3 mit Druckgas, so wie in den Fig. 3 bis 6 dargestellt, eine den Innenraum des äußeren Behälters 1 mit dem Inneren des Ventilkörpers 14 verbindende Druchgangsöffnung 20 verschließt, so daß dementsprechend die Fluidverbindung zwischen dem Innenraum des äußeren Behälters 1 und dem im Ventilkörper 14 axial verschiebbar gelagerten Abgaberöhrchen 17 des Abgabeventils 2 während der Begasung bzw. Befüllung des Innenbeutels 3 mit Druckgas unterbrochen ist. Zwischen dem Schließpfropfen 18 und dem Abgaberöhrchen 17 ist ein axial wirksames elastisches Element, insbesondere eine Schraubendruckfeder 19 angeordnet, gegen deren Wirkung unter Freigabe einer Fluidverbindung nach außen das Abgaberöhrchen 17 axial in den Ventilkörper 14 hineindrückbar ist, wobei der Schließpfropfen 18 zum Befüllen des Innenbeutels 3 mit Druckgas innerhalb des Ventilkörpers 14 in einer von der in den Innenbeutel 3 mündenden Füllöffnung 16 abgehobenen Ausgangsstellung gehalten ist, in der das Druckgas durch das axial in den Ventilkörper 14 gedrückte Abgaberöhrchen 17 hindurch und am Schließpfropfen 18 außenseitig vorbei in den Innenbeutel 3 einleitbar ist (siehe Strömungspfeile 30 in Fig. 4 und 5). Nach Befüllung des Innenbeutels 3 mit Druckgas wird der Schließpfropfen 18 entsprechend Fig. 7 unter Überwindung von den Schließpfropfen 18 in Ausgangsstellung haltenden Sperrmitteln (Umfangsrippen 22, 23) durch das noch weiter in den Ventilkörper 14 hineingedrückte Abgaröhrchen 17 in Füllöffnung-Schließstellung bewegt, in der er durch Rastmittel (Ringvorsprung 24) dauerhaft gehalten ist. Vorzugsweise ist der Schließpfropfen 18 aus einem härteren Material, insbesondere Kunststoffmaterial, wie Hart-PVC, hergestellt als der Ventilkörper 14. Entsprechend der dargestellten Ausführungsform umfaßt der Schließpfropfen 18 an der dem Abgaberöhrchen 17 zugewandten Seite eine topfartige Führungshülse 25, in die sich der dem Behälterinneren zugekehrte Teil der Schraubendruckfeder 19 hineinerstreckt und dessen dem Abgaberöhrchen 17 zugewandte äußere Umfangsrand 26 scharfkantig radial nach außen vorspringt, um unter Abstützung an der Innenseite der den Ventilkörper 14 seitlich begrenzenden Umfangswand 27 eine Bewegung des Schließpfropfens 18 aus der Füllöffnung-Schließstellung entsprechend Fig. 7 heraus zu erschweren. In dieser Stellung wird der Schließpfropfen 18 demnach sowohl durch die Schraubendruckfeder 19, den scharfkantigen Umfangsrand 26 sowie den radial nach innen ragenden Rastvorsprung 24, welcher mit dem sich radial nach außen erstreckenden Ringvorsprung 23 des Schließpfropfens 18 rastend zusammenwirkt, gehalten.The specially adapted dispensing valve will now be described in more detail with reference to FIGS. 3 to 8. The
Wie Fig. 4 erkennen läßt, liegt beim Begasen des Innenbeutels 3 das behälterinnere Ende 31 des Abgaberöhrchens 17 an einem nach oben vorstehenden, kreuzförmigen Vorsprung 32 des Schließpfropfens 18 an, wobei der Vorsprung 32 sich vom Boden der topfartigen Führungshülse 25 erstreckt.As can be seen in FIG. 4, when the
Zur Begasung wird - wie oben ausgeführt - der topfartige Schließpfropfen 18 in einer von der Füllöffnung 16 abgehobenen Stellung gehalten, und zwar durch Sperrmittel 22, 23 in Form von radial vorspringenden Umfangsrippen an der Innenseite der den Ventilkörper 14 seitlich begrenzenden Zylinderwand 27 einerseits und an der Außenseite der Führungshülse 25 andererseits. Zwischen diesen beiden radial vorstehenden Umfangsrippen sind mehere gleichmäßig über den Umfang verteilt angeordnete Durchgangsöffnungen 33 ausgebildet, durch die hindurch das Druckgas in den Innenbeutel 3 strömt (Pfeil 30 in Fig. 5).For gassing - as explained above - the pot-like closing plug 18 is held in a position raised from the filling
Die axiale Bewegung des Abgaberöhrchens 17 erfolgt durch einen nicht näher dargestellten Füllkopf.The axial movement of the dispensing
Das Abgabeventil 2 bzw. dessen Ventilkörper 14 ist in an sich bekannter Weise zentral am Behälterdeckel 34 verankert. Aus diesem Grunde ist eine nähere Beschreibung dieser Befestigungskonstruktion nicht erforderlich.The dispensing
Fig. 7 zeigt das Abgaberöhrchen 17 bei verschlossener Füllöffnung 16 in Füllgut-Austragsstellung. Das Füllgut kann entsprechend den Pfeilen 35 durch die Öffnungen 20, das Innere des Ventilkörpers 14 sowie den Fluidkanal 36 des Abgabeventils 17 hindurch ausströmen, und zwar unter der Wirkung des expandierenden Innenbeutels 3. In Fig. 8 ist das Abgabeventil 2 in Schließstellung nach Befüllung des äußeren Behälters 1 und Begasung des Innenbeutels 3.7 shows the dispensing
Unter Bezugnahme auf Fig. 1 sei noch erwähnt, daß zwischen den beiden Zusatz-Siegelstreifen 13 innerhalb des Innenbeutels 3 ein an die Füllöffnung 16 angeschlossenes Steigrohr plaziert ist, welches sich zumindest über etwa die halbe Länge des Innenbeutels 3 erstreckt. Wie eingangs dargelegt, dient dieses Steigrohr im wesentlichen nur der Erhöhung der Knickstabilität des Innenbeutels 3, so daß dieser leichter in den mit Füllgut gefüllten Behälter 1 eingetaucht werden kann, vor allem dann, wenn das Füllgut eine pastöse Masse ist.With reference to FIG. 1, it should also be mentioned that between the two additional sealing strips 13 inside the inner bag 3 a riser tube connected to the filling
In Fig. 9 ist eine Alternativkonstruktion des Abgabeventils im Bezug auf den Schließpfropfen 18 dargestellt. Bereits anhand der vorangehenden Figuren beschriebene Teile des Abgabeventils 2 sind in Fig. 9 mit denselben Bezugsziffern gekennzeichnet. Bezüglich deren Funktion wird demnach auf die Vorbeschreibung verwiesen. Das besondere an der Ausführungsform nach Fig. 9 ist, daß die Führungshülse 25 über den gesamten Umfang eng an der Innenseite der den Ventilkörper 14 seitlich begrenzenden Umfangswand 27 anliegt. Dementsprechend sind zur Begasung des Innenbeutels 3 im Boden der topfförmigen Führungshülse 25 Durchgangsöffnungen 21 angeordnet, durch die hindurch bei von der Füllöffnung 16 abgehobenem Schließpfropfen 18 die Begasung des Innenbeutels 3 erfolgt (siehe Pfeile 30). Auch die dem Schließpfropfen 18 zugeordneten Sperrmittel, die diesen in der von der Füllöffnung 16 abgehobenen Stellung während der Begasung des Innenbeutels 13 halten, sind im Vergleich zu der vorbeschriebenen Ausführungsform geändert. Die dem Ventilkörper 14 zugeordneten Sperrmittel 24 werden durch eine im Inneren des Ventilkörpers um die Füllöffnung 16 herum angeordnete, insbesondere angeformte Klemmhülse gebildet, während die dem Schließpfropfen 18 zugeordneten Sperrmittel 22 durch mehere gleichmäßig über den Umfang verteilt angeordnete Radialrippen gebildet sind, die sich mit ihrem behälterinneren Ende an dem dem Abgaberöhrchen 17 zugewandten Umfangsrand der Klemmhülse während der Begasung des Innenbeutels 3 abstützen, wodurch der Schließpfropfen 18 in einer von der Füllöffnung 16 abgehobenen Stellung entsprechend Fig. 9 gehalten ist. Nach Befüllung des Innenbeutels 3 mit Druckgas wird das Abgaberöhrchen 17 durch den nicht dargestellten Füllkopf unter Anlage an den vorbeschriebenen Vorsprung 32 noch weiter in den Behälter hineingedrückt. Bei dieser Bewegung werden die Radialrippen 22 in die Klemmhülse 24 gepreßt, so daß der gleichermaßen in die Füllöffnung 16 gepreßte Schließpfropfen 18 in Füllöffnung-Schließstellung gehalten wird. Zusätzlich wird der Schließpfropfen 18 in dieser Stellung durch die Wirkung der Druckfeder 19 sowie den scharfkantigen Umfansrand 26 gehalten, der sich an der Innenseite der den Ventilkörper 14 seitlich begrenzenden Umfangswand 27 regelrecht festkrallt. Der Innenbeutel 3 ist damit nach Begasung dauerhaft fluiddicht abgeschlossen. Alle übrigen Teile des in Fig. 9 dargestellten Aggabeventils 2 sind mit denjenigen des vorbeschriebenen Abgabeventils gleich, so daß - wie bereits oben ausgeführt - eine nähere Beschreibung dieser Teile an dieser Stelle entbehrlich ist.9 shows an alternative construction of the dispensing valve in relation to the
