Definitions
- the present invention relates to a device for metered delivery of a fluid from a tubular bag.
- tubular pouches here are made of plastic film produced bags that are completely closed. Such tubular bags are machined by means of appropriate folding of a plastic film, whereupon they are completely closed by appropriate welds. Such tubular bags then have opening devices, which consists essentially of a nozzle with rand perennialm flange and this flange is welded onto the bag, wherein a cutting element is held in the nozzle and is screwed by a screw cap, so that at the first opening of the writing cap the Cutting element to the film moves in a screwing motion while the fully closed tubular bag opens.
- opening devices are known, for example from the JP 7040982 , the WO 9900308A . WO 2004/083055 or even from the EP 1533240 . EP 1795456 or the CH 695019 , These tubular bags and their opening device are mainly used in the food industry. These closures are particularly widespread in the field of fruit juices, mixed milk drinks or other types of beverages.
- the EP 1228972 A1 discloses a method for introducing an outlet opening into a provided with an inner film packaging, in particular a carton, inserted in the emptying of powdery, granular or pasty products or liquids with a Einstechtülle in one of the inner film covered outlet opening of an inside arranged on the inner film adapter ring becomes. Subsequently, the injection spout is rotated, the outlet is at least largely cut free and created a sealing connection with the adapter ring.
- tubular bags with opening devices are also known in which the opening device is designed as a simple screw cap, wherein the closure device is welded between two film edges of the container.
- a cutting device cuts open a film of the tubular bag, such as from the EP 2143658 known or variants in which the bag itself remains open, but the closure has a sealing membrane, which is subsequently pierced by a screw cap.
- Such solutions show, for example, the US 6273307 or the US 2008/0073348 .
- Such and similar solutions are typically known in so-called refill bags as they are used in particular in the field of cosmetics for liquid soaps, shower or hair shampoos. With the refill bag then a solid container is filled, in which case the actual closure of that container is unscrewed and screwed back after the refilling process.
- the metering pump preferably being realized as a disposable pump made of plastic.
- the tubular bag 2 shown here and the arrangement of the inventive device 1 is a schematic representation.
- the tubular bag 2 must have in this case a lower flat top surface 21, opposite to a second cover surface or a simple folding can lie. This folding edge is designated 20.
- the tubular bag is welded and the corresponding welding edges are designated 22.
- the device 1 can be attached at any location on these surfaces of the tubular bag.
- the tubular bag can in this case either consist of a pure plastic film or of a film which is multi-layered and has, for example, a paper or cardboard layer, an aluminum coating and on the outer sides in each case a plastic coating.
- the device 1 consists in principle of only two parts, namely a metering pump 3 and a nozzle 4, which is referred to below as the second nozzle.
- the metering pump is preferably a rotary metering pump in the Fig. 1 and 2 recognizable in the side view.
- a pump housing 30 which is covered by a bearing cap 31.
- the metering pump shown here has, for example, two vane rotors, which act in a counter-rotating manner similar to a gear pump move.
- an outlet 32 which may be in communication with a dispensing device, not shown here, for example via a hose which would be attachable to this outlet.
- the tubular bag can also be attached directly hanging and the outlet 32 are located above the place where the metered delivery of the contents.
- the outlet 32 opposite one recognizes in the Fig. 2 a first nozzle 33, which is arranged on the suction side and thus can also be referred to as Einsaugstutzen.
- This first neck 33 has an external thread 36.
- the first neck 33 engages in the second neck 4, which has a corresponding internal thread.
- the Fig. 1 now shows the device 1 before its first use, ie in a storage and transport position.
- Fig. 2 is now the same situation but shown in the usage position.
- the arrow R indicates that the metering pump 3 has been rotated in the direction of arrow R, in the present case by 360 °.
- the thread 36 on the first connecting piece 33 is no longer visible, and the first connecting piece 33 can no longer be seen above the second connecting piece 4 either.
- the lower end of the first nozzle 33 which is provided with an opening means 34 at its inlet end, is now recognized.
- This opening means 34 has now cut open the film of the tubular bag 2 and the cut-open part Only now there is a continuous connection between the metering pump 3 and the interior of the tubular bag 2. In this way, a good can be aseptically filled, transported completely closed and opened without contamination. It makes sense to also use a metering pump that seals the connection between the intake-side first port 33 and the outlet port 32 in any position.
- a pump is preferably designed as a disposable pump.
- the tubular bag with only the second port 4
- the metering pump 3 is made as a reusable pump, which remains with the user.
- this would also have a first, suction-side nozzle 33 with a corresponding opening means 34.
- this first stub 33 would also have an external thread 36, which fits on a not visible here internal thread of said second stub 4.
- the device 1 according to the invention is represented overall, but in the state not mounted on the tubular bag 2.
- This second port 4 has a terminal flange 41.
- This flange 41 has on its welding side, for example, a plurality of circumferential power-conducting ribs 42. These serve to make an intimate connection between the second nozzle 4 and the tube bag 2 during ultrasonic welding.
- the entire device 1 is shown in the transport position. It can be seen that the first neck 33 with its opening means 34 is still completely within the second neck 4 and does not protrude from this.
- the second nozzle 4 is now in the Fig. 4 shown by itself in a vertical diametrical section.
- a connecting pipe section 43 forms the actual nozzle and to these a terminal flange 41 is formed.
- the flange 41 which faces the tubular bag in the mounted state, is provided with the mentioned energy-conducting ribs 42.
- the connecting tube section 43 has an internal thread 44. This internal thread is designed such that it fits the external thread 36 on the first connecting piece 33.
- the terminal flange 41 is not directly connected to the connecting pipe section 43, but the connection is made via a conically outwardly directed connecting wall 45.
- the device 1 is preferably completely assembled and attached to the tubular bag 2, the customer or consumer delivered.
- the first nozzle 33 is provided with opening means 34, in particular perforating or cutting teeth 35, it must be ensured that the metering pump 3 and the thus firmly connected first nozzle 33 remain in this transport position during transport and storage can not unintentionally rotate relative to the second port 4. Because depending on the direction of rotation, either the metering would dissolve from the second port 4, and thus lost, or if he would turn in the opposite direction, the opening means 34 would come into contact with the film of the tubular bag 2 and possibly the tubular bag would thereby perforated and thus partially open, whereby the shelf life would of course no longer exist.
- a securing means 5 is preferably present.
- This securing means can be formed in various ways.
- a securing means 5 realized as a guarantee strip, which has internally formed stop cam 52, and outside, for example, can be provided with a tear tab 53.
- Stop cam 52 may be formed with corresponding radially outwardly directed locking ribs 53 which are formed on the pump housing 30 of the metering pump 3 at the junction of the first nozzle 33 to the housing 30, as for example the Fig. 3 shows.
- a second embodiment of a securing means 5 consists in an elevation 54 in the inlet region 37 of the first nozzle 33.
- This cam-like elevation 54 fits in the assembled state to a Einrastvertiefung 55, which is formed by two opposing ramp-like elevations in the internal thread 44 of the second nozzle 4.
- the opening means 34 which preferably consist of perforating and / or cutting teeth 35, lie completely in the region of the connecting pipe section 43 of the second nozzle 4. It is quite possible, this second form of securing means 5 with the first version of a securing means in the form of a guarantee strip 51 to combine.
- the metering pump is shown by itself. Accordingly clearly recognizes the pump housing 30, the bearing cap 31 and integrally formed on the pump housing outlet 32 and the first port 33, which serves as an inlet nozzle and with the mentioned external thread 36 is provided. On the pump housing 30 can be seen two diametrically opposed locking ribs 53, which in the Fig. 7 are shown enlarged as a section. The transition region of the first nozzle 33 to the pump housing 30 is formed by a circumferential sealing ramp 38. For the stability of the latching rib 53, this is integrally formed on the one hand on the sealing bead and on the other hand on the pump housing 33.
- this latching rib 53 has been described only in cooperation with a securing means 5 in the form of a guarantee strip 51 with corresponding stop cam 52.
- the same locking ribs 53 can also be used to secure the metering pump 3 relative to the second port 4.
- the second port 4 has in a preferred embodiment at the, the flange 41 opposite end of the connecting pipe section 43 a collar 47 and between this collar 47 and the flange 41 a plurality of axially extending ribs 48. These ribs 48 hold the collar 47 deformation-resistant relative to the flange 41.
- Anti-locking means are now mounted on the collar 47, on the side facing away from the flange 41, which engage with the latching ribs 53 on the pump housing 30 as soon as the metering pump 3 is completely screwed into the second socket 4.
- In the simplest form could be directly in an upper ramp portion of the connecting pipe section 43 of the second nozzle 4 at least one Provide catch notch 56.
- two latching notches 56 are provided in the region of the collar 47. These latching notches 56 are formed by two counter-rotating latching ramps 57 formed on the collar 47. This is particularly clear in the enlarged section in FIG Fig. 9 represented and recognizable.
- the inventive device 1 for the metered delivery of a fluid from a tubular bag 2 not only guarantees aseptic delivery of the packaged goods and an absolutely hygienic opening of the tubular bag, but has thanks to double seal an at least approximately gas-tight closure of the tubular bag by the inventive device.
- a first seal as already mentioned and described, between the first port 33 and the second port 4.
- the connecting pipe section 43 on its inner side a first sealing lip or sealing bead 46 which in the free area of the connecting pipe section 43 below the conical wall 45 is formed.
- This is in the 10 and 11 shown.
- the second sealing region can be seen, which forms a seal between the second nozzle 4 and the pump housing 30. This sealing area is in the Fig.
- a circumferential annular sealing ramp 38 is formed, which has a ramp-like inclination.
- This annular sealing ramp 38 is located in the Fig. 12a on top of the sealing head 49 'at the upper end of the sealing ring wall 49.
- the pump housing is completely screwed with the first port 33 in the second port 4.
- the latching rib 43 is now in the latching notch 56, the boundary of which forms the latching ramp 57, which in the Fig. 12a and 12b can be seen cut.
- the sealing ring wall is now deformed by the annular sealing ramp 38 of the pump housing 31 inwardly curved.
- the annular circumferential sealing head 49 ' is absolutely sealingly against the sealing ramp 38.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur dosierten Abgabe eines Fluids aus einem Schlauchbeutel.The present invention relates to a device for metered delivery of a fluid from a tubular bag.
Unter Schlauchbeutel werden hier aus Kunststofffolie erzeugte Beutel verstanden, die vollständig verschlossen sind. Solche Schlauchbeutel werden maschinell gefertigt mittels entsprechender Faltung einer Kunststofffolie, worauf diese durch entsprechende Schweissnähte vollständig verschlossen werden. Solche Schlauchbeutel weisen dann Öffnungsvorrichtungen auf, die im wesentlichen aus einem Stutzen mit randständigem Flansch besteht und dieser Flansch auf den Beutel aufgeschweisst ist, wobei im Stutzen ein Schneidelement schraubbeweglich gehalten ist und mittels einer Schraubkappe betätigbar ist, so, dass bei der Erstöffnung der Schreibkappe das Schneidelement zur Folie hin in einer Schraubbewegung sich bewegt und dabei den vollständig geschlossenen Schlauchbeutel öffnet. Der Vorteil solcher Schlauchbeutel mit einer entsprechenden Öffnungsvorrichtung besteht darin, dass bis zum effektiven Moment des Gebrauchs der Inhalt des Schlauchbeutels vollkommen aseptisch verpackt und geschützt bleibt. Typische Beispiele solcher Öffnungsvorrichtungen sind beispielsweise bekannt aus der
Die
Schlauchbeutel mit Öffnungsvorrichtungen sind aber auch bekannt, bei denen die Öffnungsvorrichtung als einfacher Schraubverschluss gestaltet ist, wobei die Verschlussvorrichtung zwischen zwei Folienränder des Behälters eingeschweisst wird. Hierbei gibt es Varianten, bei denen ebenso eine Schneidvorrichtung eine Folie des Schlauchbeutels aufschneidet, wie beispielsweise aus der
In der Gastronomie werden heute jedoch wesentlich grössere Schlauchbeutel als Nachfüllbehältnisse angeboten. Insbesondere an Schnellimbisslokale werden dickflüssige, pastöse und oft texotrope Lebensmittel in grösseren Gebinden abgegeben und aus diesen meist mit einer Handpumpe entnommen. Dies sind heute insbesondere grosse Büchsen oder Kunststoffgebinde, die mit einem einfachen Schraubverschluss versehen sind und auf die eine handbetätigbare Pumpe aufgesetzt wird. Dies hat verschiedenste Nachteile. Zum einen werden solche Behältnisse kaum aseptisch abgefüllt und nach der Erstöffnung muss eine wiederverwendbare Pumpe aufgesetzt werden, die zuvor gereinigt werden muss. Hinzu kommt, dass beim Entfernen des Schraubverschlusses und dem Aufsetzen der entsprechenden Pumpe Umgebungsluft in das Gebinde gelangt. Damit ist der Inhalt nicht mehr aseptisch. Auch nach dem Aufsetzen der Pumpe muss in das Behältnis Luft nachströmen können, um das herausgepresste Gut zu ersetzen, um einen Unterdruck im Gebinde zu vermeiden. Da aber viele solche in der Gastronomie verwendeten Lebensmittelprodukte durch den Kontakt mit der Umgebungsluft oxidieren oder sonstwie Schaden nehmen können, müssen diese Produkte folglich durch entsprechende Konservierungsmittelzusätze besser haltbar gemacht werden. Dies wird aber je länger je mehr von den Konsumenten nicht mehr akzeptiert.In gastronomy, however, much larger tubular bags are offered today as refill containers. In particular at fast food restaurants, viscous, pasty and often texotropic foods are dispensed in larger containers and are usually removed from them with a hand pump. These are today in particular large cans or plastic containers, which are provided with a simple screw cap and on which a hand-operated pump is placed. This has a variety of disadvantages. On the one hand, such containers are hardly bottled aseptically and after the first opening a reusable pump must be placed, which must be cleaned beforehand. In addition, when removing the screw cap and placing the appropriate pump ambient air enters the container. Thus, the content is no longer aseptic. Even after the pump has been put in place, air must be able to flow into the container to replace the pressed-out material in order to avoid a negative pressure in the container. However, since many such food products used in the catering industry can oxidise or otherwise be damaged by the contact with the ambient air, these products must therefore be better preserved by adding appropriate preservative additives. However, this is no longer accepted by consumers more and more.
Es ist nunmehr die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur dosierten Abgabe eines Fluids aus einem Schlauchbeutel zu schaffen, mittels dem die vorgenannten Probleme vermieden werden können. Diese Aufgabe löst eine Vorrichtung gemäß Anspruch 1.It is now the object of the present invention to provide a device for the metered delivery of a fluid from a tubular bag, by means of which the aforementioned problems can be avoided. This object is achieved by a device according to
Dies lässt sich besonders einfach und preiswert realisieren, indem die Dosierpumpe vorzugsweise als eine Einwegpumpe aus Kunststoff gefertigt realisiert ist.This can be realized in a particularly simple and inexpensive manner by the metering pump preferably being realized as a disposable pump made of plastic.

Der hier dargestellte Schlauchbeutel 2 und die Anordnung der erfindungsgemässen Vorrichtung 1 ist eine schematische Darstellung. Der Schlauchbeutel 2 muss in diesem Falle eine untere ebene Deckfläche 21 besitzen, der gegenüber eine zweite Deckfläche oder eine einfache Faltung liegen kann. Diese Faltkante ist mit 20 bezeichnet. Entlang den Längskanten ist der Schlauchbeutel verschweisst und die entsprechenden Schweisskanten sind mit 22 bezeichnet. In einer einfacheren Version würde man den Schlauchbeutel 2 praktisch kissenartig gestalten und entlang von drei Kanten verschweissen. In diesem Falle lässt sich die Vorrichtung 1 an einem beliebigen Ort auf diesen Flächen des Schlauchbeutels anbringen. Da in jenem Falle jedoch die Vorrichtung 1 lediglich von oben sichtbar wäre und man so nur wenig von der Vorrichtung erkennen könnte, hat man die hier dargestellte symbolische Gestaltungsform gewählt. Der Schlauchbeutel kann hierbei entweder aus einer reinen Kunststofffolie oder aus einer Folie bestehen, die mehrlagig ist und beispielsweise eine Papier- oder Kartonschicht, eine Aluminiumbeschichtung und auf den Aussenseiten jeweils eine Kunststofffbeschichtung aufweist.The
Die Vorrichtung 1 besteht im Prinzip aus lediglich zwei Teilen, nämlich einer Dosierpumpe 3 und einem Stutzen 4, der nachfolgend als zweiter Stutzen bezeichnet wird. Die Dosierpumpe ist bevorzugterweise eine Rotationsdosierpumpe in den

Eine zweite Ausführungsform eines Sicherungsmittels 5 besteht in einer Erhebung 54 im Einlaufbereich 37 des ersten Stutzens 33. Diese nockenartige Erhebung 54 passt im zusammengebauten Zustand zu einer Einrastvertiefung 55, welche durch zwei gegenläufige rampenartige Erhebungen im Innengewinde 44 des zweiten Stutzens 4 eingeformt ist. In der Montagelage vor der Erstbenutzung wird der erste Stutzen 33 in den zweiten Stutzen 4 soweit eingeschraubt, dass die Erhebung 54 in der Einrastvertiefung 55 zum Eingriff kommt. In dieser Position liegen die Öffnungsmittel 34, die vorzugsweise als Perforier- und/oder Schneidzähne 35 bestehen, vollständig im Bereich des Verbindungsrohr-Abschnittes 43 des zweitens Stutzens 4. Es ist durchaus möglich, diese zweite Form der Sicherungsmittel 5 mit der ersten Version eines Sicherungsmittels in Form eines Garantiebandes 51 zu kombinieren.A second embodiment of a securing means 5 consists in an elevation 54 in the
In der
Bisher wurde diese Einrastrippe 53 lediglich im Zusammenwirken mit einem Sicherungsmittel 5 in der Gestalt eines Garantiebandes 51 mit entsprechenden Anschlagsnocken 52 beschrieben. Dieselben Einrastrippen 53 können aber auch zur Sicherung der Dosierpumpe 3 relativ zum zweiten Stutzen 4 zum Einsatz kommen. Der zweite Stutzen 4 besitzt in einer bevorzugten Ausführungsform an dem, dem Flansch 41 gegenüberliegenden Ende des Verbindungsrohr-Abschnittes 43 einen Kragen 47 und zwischen diesem Kragen 47 und dem Flansch 41 eine Vielzahl von axial verlaufenden Rippen 48. Diese Rippen 48 halten den Kragen 47 verformungssteif relativ zum Flansch 41. Auf dem Kragen 47, auf dem, dem Flansch 41 abgewendeten Seite sind nun Gegensicherungsmittel angebracht, die mit den Einrastrippen 53 am Pumpengehäuse 30 im Eingriff kommen, sobald die Dosierpumpe 3 vollständig im zweiten Stutzen 4 eingeschraubt ist. In der einfachsten Form könnte man direkt in einem oberen Rampenbereich des Verbindungsrohr-Abschnittes 43 des zweiten Stutzens 4 mindestens eine Einrastkerbe 56 vorsehen. Im vorliegenden Fall sind zwei Einrastkerben 56 im Bereich des Kragens 47 angebracht. Diese Einrastkerben 56 werden gebildet durch zwei auf den Kragen 47 angeformte, gegenläufige Einrastrampen 57. Dies ist besonders deutlich im vergrösserten Abschnitt in
Die erfindungsgemässe Vorrichtung 1 zur dosierten Abgabe eines Fluids aus einem Schlauchbeutel 2 garantiert nicht nur eine aseptische Anlieferung der verpackten Ware und eine absolut hygienische Öffnung des Schlauchbeutels, sondern besitzt dank doppelter Dichtung eine mindestens annähernd praktisch gasdichte Verschliessung des Schlauchbeutels durch die erfindungsgemässe Vorrichtung. Hierzu besteht eine erste Dichtung, wie bereits erwähnt und beschrieben, zwischen dem ersten Stutzen 33 und dem zweiten Stutzen 4. Hier besitzt der Verbindungsrohr-Abschnitt 43 auf seiner Innenseite eine erste Dichtlippe oder Dichtwulst 46, die im freien Bereich des Verbindungsrohr-Abschnittes 43 unterhalb der konischen Wand 45 angeformt ist. Dies ist in den
