Die Kopfsiegelnaht (12) ist an wenigstens einer Stelle (14, 15) zwischen spout (13) und äußerem Rand ungesiegelt (Teilsiegelung), so daß beim Befüllen des Beutels (10) Luft durch diese ungesiegelte Stelle (14, 15) aus dem Beutel (10) heraus nach außen entweichen kann (Pfeil 16).Tubular bag (10) with a spout (13) and a standing base (11) sealed in in the area of a top sealing seam (12). The top sealing seam (12) is unsealed (partial sealing) at at least one point (14, 15) between the spout (13) and the outer edge, so that when the bag (10) is filled, air flows out of the bag through this unsealed point (14, 15) (10) can escape outwards (arrow 16).

Description

Die vorliegende Erfindung betrifft einen Schlauchbeutel, insbesondere Standbeutel, mit einem im Bereich einer Kopfsiegelnaht eingesiegelten Ausgießer bzw. spout, und gegebenenfalls Boden, insbesondere Standboden, sowie ein Verfahren zur Befüllung eines derartigen Schlauchbeutels.The The present invention relates to a tubular bag, in particular Stand-up pouch, with a sealed in the region of a top seal seam spout or spout, and possibly ground, in particular, ground floor, as well a method of filling such a tubular bag.

Schlauchbeutel dieser Art sind allgemein bekannt, zum Beispiel aus der auf die Anmelderin zurückgehenden DE 202 12 251 U1 . Sie dienen zur Aufnahme von flüssigen, pastösen, pulverigen oder anderweitig rieselfähigen Produkten. Problematisch ist die Befüllung derartiger Schlauchbeutel durch den spout bzw. eine in diesem ausgebildete Öffnung hindurch, da durch diese Öffnung auch die sich im Beutelinnern befindliche Luft entweichen muß. Dies kann dazu führen, daß mit der aus dem Beutel nach außen strömenden Luft eingefüllter Beutelinhalt nach außen mitgerissen wird. Das Ergebnis sind unerfreuliche Verschmutzungen der Abfüllanlagen und auch Abweichungen beim Füllgewicht. Darüber hinaus leidet darunter ganz erheblich die Füllgeschwindigkeit. Man kann die vorgenannten Probleme nämlich im wesentlichen nur dadurch lösen, daß relativ langsam eingefüllt wird, wobei im Füllkopf zusätzlich wenigstens eine Entlüftungsöffnung vorgesehen sein muß, die zur Folge hat, daß der Füllquerschnitt entsprechend kleiner wird.Tubular bags of this type are well known, for example from the date of the applicant DE 202 12 251 U1 , They are used to hold liquid, pasty, powdery or otherwise free-flowing products. The problem is the filling of such tubular bag through the spout or an opening formed in this, as through this opening and the air inside the bag must escape. This can lead to the bag content filled out of the bag with the air flowing outwards being entrained to the outside. The result is unpleasant soiling of the bottling plants and also deviations in the filling weight. In addition, the filling speed suffers considerably. Namely, it is possible to solve the aforementioned problems essentially only by filling in relatively slowly, wherein at least one venting opening must additionally be provided in the filling head, with the result that the filling cross-section becomes correspondingly smaller.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Schlauchbeutel und ein Verfahren zur Befüllung desselben zur Verfügung zu stellen, mit dem all die vorgenannten Probleme vermieden werden können. Insbesondere soll eine saubere und schnelle Befüllung von Schlauchbeuteln der hier fraglichen Art möglich sein.Of the The present invention is therefore based on the object, a tubular bag and a method of filling same available to provide, with which all the aforementioned problems are avoided can. In particular, a clean and fast filling of tubular bags is the here questionable type possible be.

Diese Aufgabe wird hinsichtlich eines Schlauchbeutels durch die kennzeichnenden Merkmale des Anspruches 1 und hinsichtlich des Verfahrens durch die kennzeichnenden Merkmale des Anspruches 3 gelöst, wobei Anspruch 2 eine bevorzugte Schlauchbeutel-Konstruktion betrifft.These Task is in terms of a tubular bag by the characterizing Features of claim 1 and in terms of the method by the characterizing features of claim 3 are solved, wherein Claim 2 relates to a preferred tubular bag construction.

Der Kern der vorliegenden Erfindung liegt also darin, daß die Kopfsiegelnaht zunächst einer „Teilsiegelung" unterworfen wird dergestalt, daß an wenigstens einer Stelle zwischen spout und äußerem Rand der Kopfsiegelnaht eine ungesiegelte Stelle angeordnet ist, so daß beim Befüllen des Beutels Luft durch diese ungesiegelte Stelle aus dem Beutel nach außen entweichen kann. Es ist also nicht mehr erforderlich, daß die sich im Beutelinnern befindliche Luft beim Befüllen des Beutels durch den spout bzw. durch die Einfüllöffnung hindurch nach außen entweichen muß mit all den vorstehend genannten Nachteilen.Of the The core of the present invention is therefore that the top seal first subjected to a "partial sealing" in such a way that at least a place between spout and outer edge the head seal seam is arranged an unsealed area, so that when filling the Escape the air from the bag through this unsealed area to the outside can. So it is no longer necessary that in the bag inside air present during filling of the bag escape through the spout or through the filling opening to the outside must with all the above-mentioned disadvantages.

Vorzugsweise weist die Kopfnaht zu beiden Seiten des spout jeweils wenigstens eine ungesiegelte Stelle auf, so daß innerhalb kürzester Zeit viel Luft aus dem Beutelinnern nach außen entweichen kann mit der Folge, daß die Füllgeschwindigkeit entsprechend erhöht ist.Preferably has the top seam on both sides of the spout at least each an unsealed area so that within a shortest time Time much air can escape from the bag inside to the outside Consequence, that the Filling speed increased accordingly is.

Nach dem Befüllen des Beutels mit flüssigem, pastösem oder rieselfähigem Beutelinhalt durch den spout hindurch wird die wenigstens eine ungesiegelte Stelle der Kopfsiegelnaht versiegelt und damit fluiddicht verschlossen. Man spricht dabei von einer sogenannten „Restsiegelung".To the filling of the bag with liquid, pasty or free-flowing Bag contents through the spout will be the at least one unsealed Place the top seal sealed and thus sealed fluid-tight. This is called a so-called "residual sealing".

Nachstehend wird anhand der beigefügten Zeichnung ein Ausführungsbeispiel eines erfindungsgemäßen Schlauchbeutels und des Verfahrens zur Befüllung desselben näher erläutert. Es zeigen:below is based on the attached drawing an embodiment a tubular bag according to the invention and the method of filling closer to it explained. Show it:

1 einen im Bereich der Kopfsiegelnaht nur teilweise versiegelten Schlauchbeutel unter schematischer Darstellung der Befüllung desselben; und 1 a tubular bag which is only partially sealed in the region of the top seal seam, with a schematic representation of the filling thereof; and

2 den Schlauchbeutel nach Befüllung und Restsiegelung. 2 the tubular bag after filling and residual sealing.

Der in 1 dargestellte Schlauchbeutel 10 ist als Standbeutel mit Standboden 11 und einem im Bereich einer Kopfsiegelnaht 12 eingesiegelten Ausgießer bzw. spout 13 ausgebildet. Die Kopfsiegelnaht 12 ist zu beiden Seiten des spout 13 nur teilgesiegelt, d.h. weist jeweils eine ungesiegelte Stelle 14, 15 auf, so daß beim Befüllen des Beutels 10 Luft durch diese ungesiegelten Stellen 14, 15 aus dem Beutel 10 heraus nach außen entweichen kann. Diese Luftströmung ist mit der Bezugsziffer 16 in 1 gekennzeichnet. Des weiteren ist die Befüllung des Schlauchbeutels 10 in 1 mit dem Pfeil 17 gekennzeichnet.The in 1 illustrated tubular bag 10 is as a stand-up pouch with a floor 11 and one in the area of a top seal 12 sealed spout or spout 13 educated. The head seal seam 12 is on both sides of the spout 13 only partially sealed, ie, each has an unsealed area 14 . 15 on, so that when filling the bag 10 Air through these unsealed areas 14 . 15 out of the bag 10 out to the outside. This air flow is indicated by the reference numeral 16 in 1 characterized. Furthermore, the filling of the tubular bag 10 in 1 with the arrow 17 characterized.

Nach Befüllung des Schlauchbeutels 10 in der anhand der 1 beschriebenen Weise erfolgt die sogenannte Restsiegelung, mittels der die ungesiegelten Stellen 14, 15 der Kopfsiegelnaht 12 versiegelt und damit fluiddicht verschlossen werden. Diese Restsiegelung ist in 2 mit der Bezugsziffer 18 gekennzeichnet.After filling the tubular bag 10 in the basis of the 1 described manner, the so-called residue-sealing, by means of which the unsealed areas 14 . 15 the head seal 12 sealed and thus sealed fluid-tight. This residual seal is in 2 with the reference number 18 characterized.

Ergänzend zu den vorstehenden Ausführungen sei noch erwähnt, daß sowohl die Teilsiegelung als auch die Restsiegelung vorzugsweise als Ultraschall-Siegelung durchgeführt wird. Die entsprechenden maschinentechnischen Vorrichtungen dafür stehen in der Regel zur Verfügung, so daß auch aus diesem Grunde das erfindungsgemäße Verfahren vorteilhaft einsetzbar ist, und zwar auch auf herkömmlichen Abfüllanlagen.In addition to the above, it should be mentioned that both the partial sealing and the residual sealing are preferably carried out as ultrasonic sealing. The corresponding technical equipment for ste hen usually available, so that for this reason, the inventive method is advantageously used, even on conventional bottling plants.

Die Größe bzw. Länge der ungesiegelten Stellen 14, 15 und der damit verbundenen Öffnungen des Behälters zum Entweichen von Luft aus dem Behälterinnern während der Befüllung des Behälters hängt natürlich von der Art des Produkts, insbesondere der Viskosität desselben ab, mit dem der Beutel 10 befüllt werden soll.The size or length of the unsealed areas 14 . 15 and the associated openings of the container for the escape of air from the container interior during the filling of the container of course depends on the nature of the product, in particular the viscosity thereof, with which the bag 10 should be filled.

Schließlich sei zum Stand der Technik noch darauf hingewiesen, daß schon vorgeschlagen worden ist, das Innere eines zu befüllenden Behälters zu evakuieren. Bei Schlauchbeuteln der hier fraglichen Art ist diese Technik jedoch nicht einsetzbar, zumindest nicht zweckmäßig. Auch aus diesem Grunde stellt sich die beschriebene Erfindung als vorteilhaft gegenüber dem Stand der Technik dar.Finally, be to the state of the art still pointed out that already has been proposed, the interior of a to be filled container to evacuate. For tubular bags of the type in question this is However, technology can not be used, at least not appropriate. Also For this reason, the invention described is advantageous over the Prior art.

Sämtliche in den Anmeldungsunterlagen offenbarten Merkmale werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All Features disclosed in the application documents are considered to be essential to the invention as far as they are individually or in combination with respect to State of the art are new.
