B e s c h r e i b u n gDescription
Die Erfindung betrifft ein Verfahren zum Herstellen eines flaschen- oder schlauchartigen Behälters, insbesondere Schlauchbeutels, mit einem Schlauchbeutelkörper und einem ein¬ gesiegelten Boden, insbesondere Standboden, sowie ggf. eingesiegelten Deckel- und/oder Schulterteil sowie einen solchen Schlauchbeutel gemäß den Oberbegriffen der Patentan- spräche 1, 17 und 18.The invention relates to a method for producing a bottle-like or hose-like container, in particular tubular bag, with a tubular bag body and a sealed bottom, in particular floor, and possibly sealed lid and / or shoulder part and such a tubular bag according to the preambles of the patent talk to 1, 17 and 18.
Schlauchbeutel mit eingesiegelten Bodenteilen sowie ggf. eingesiegelten Deckel- und/oder Schulterteilen werden vielfach zum Abfüllen von flüssigen, pastösen oder festen Gütern verwendet. Als problematisch bei den bisher bekannten Schlauchbeuteln dieser Art hat sich jedoch erwiesen, daß diese in aller Regel wenig standfest sind. Darüber hinaus erweist sich das Einsiegeln des Bodens sowie ggf. auch des Deckel- und/oder Schulterteils als problematisch, da diese exakt in den Schlauchbeutelkörper eingepaßt werden müssen, wobei das Einschieben der Boden- bzw. Deckel- und/oder Schulterteile in den Schlauchbeutelkörper schwierig durchzuführen ist und unter Umständen zur Faltenbildung, respektive zu einem ungleichmäßigen Kontakt zwischen Boden-, Deckel- und/oder Schulterteil und Schlauchbeutelkörper und einer damit einhergehenden Undichtigkeit führt.Tubular bags with sealed bottom parts and possibly sealed lid and / or shoulder parts are widely used for filling of liquid, pasty or solid goods. As a problem with the previously known tubular bags of this type, however, has proven that these are usually less stable. In addition, the sealing of the bottom and possibly also of the lid and / or shoulder part proves problematic because they must be fitted exactly in the tubular pouch body, the insertion of the bottom or lid and / or shoulder parts in the tubular pouch body difficult and possibly leads to wrinkles, respectively uneven contact between bottom, lid and / or shoulder part and tubular bag body and a concomitant leakage.
Um diese Problematik zu umgehen, wurde in der Vergangenheit der Boden sowie die kor- respondierenden einzusiegelnden kopfseitigen Abschluß-, d.h. Deckel- und/oder Schul¬ terteile etwas kleiner als der Schlauchbeutelkörper sowie ggf. mit einer Ausnehmung oder einer Falte bzw. einem Knick ausgestaltet und in entsprechender Form in den Schlauch¬ beutelkörper eingeführt. Derartige Boden- bzw. Deckel- und/oder Schulterteile sind jedoch unter Dichtigkeitsgesichtspunkten problematisch, da zumindest abschnittsweise zwischen Boden- bzw. Deckel- und/oder Schulterteil und Schlauchbeutelkörper ein Spalt verbleibt, der mit Siegelmedium verfüllt werden muß, um einen dichten Schlauchbeutel zu gewährleisten, was jedoch einen erhöhten Materialbedarf an Dichtmedium erfordert.In order to circumvent this problem, in the past the bottom and the corresponding head-end closure elements to be sealed in, ie lid and / or shoulder parts, have been designed somewhat smaller than the tubular pouch body and optionally with a recess or a fold or a kink and introduced into the Schlauch¬ bag body in a corresponding form. However, such bottom or top and / or shoulder parts are problematic from a sealing point of view, since at least in sections a gap remains between bottom or top and / or shoulder part and tubular pouch body, which must be filled with sealing medium to ensure a tight tubular bag, but this requires an increased material requirement for sealing medium.
Der Erfindung liegt die Aufgabe zugrunde, die vorgenannte Problematik dahingehend zu verbessern, daß ein Verfahren zur Herstellung eines Schlauchbeutels sowie ein entspre¬ chender Schlauchbeutel zur Verfügung gestellt wird, der einen eingesiegelten Boden sowie ggf. ein eingesiegeltes Deckel- und/oder Schulterteil aufweist, wobei das Boden¬ bzw. Deckel- und/oder Schulterteil mit einfachen Maßnahmen und kostengünstig in den Schlauchbeutelkörper einsiegelbar ist, dem Schlauchbeutel ein hohes Standvermögen und eine gute Griffigkeit sowie eine hohe Dichtigkeit verleiht, und einen geringen Material¬ bedarf, insbesondere an Siegelmedium, erfordert.The invention has for its object to improve the aforementioned problem in that a method for producing a tubular bag and a corre sponding tubular bag is provided having a sealed bottom and possibly a sealed lid and / or shoulder part, said the Boden¬ or lid and / or shoulder part with simple measures and inexpensive in the tubular pouch body is sealable, the tubular bag gives a high level of stability and a good grip and a high density, and a low Material¬ required, in particular to sealing medium requires.
Diese Aufgabe wird durch ein Verfahren gemäß Patentanspruch 1 sowie durch einen Schlauchbeutel gemäß den Patentansprüchen 17 und 18 gelöst.This object is achieved by a method according to claim 1 and by a tubular bag according to claims 17 and 18.
Insbesondere wird die Aufgabe durch ein Verfahren zur Herstellung eines Schlauchbeu¬ tels mit einem Schlauchbeutelkörper und einem eingesiegelten Boden, insbesondere Standboden, sowie gegebenenfalls eingesiegeltem Deckel- und/oder Schulterteil gelöst, wobei zumindest der Boden sowie gegebenenfalls das Deckel- und/oder das Schulterteil in den Schlauchbeutelkörper eingeführt wird, wobei der Schlauchbeutelkörper vor dem und/oder während des Einführen(s) des Bodens sowie gegebenenfalls des Deckel- und/oder des Schulterteils zumindest im Einführbereich mit einem vorbestimmten Maß gedehnt, vorzugsweise aufgeweitet, wird.In particular, the object is achieved by a method for producing a Schlauchbeu¬ means with a tubular bag body and a sealed bottom, especially bottom, and optionally sealed lid and / or shoulder part, wherein at least the bottom and optionally the lid and / or the shoulder part in the tubular pouch body is introduced, wherein the tubular pouch body before and / or during the insertion (s) of the bottom and optionally the lid and / or the shoulder part at least in the insertion area with a predetermined amount stretched, preferably expanded.
Ein wesentlicher Punkt der Erfindung liegt darin, daß auf diese Weise ein paßgenaues Boden- bzw. Deckel- und/oder Schulterteil verwendet werden kann, das in den Schlauch¬ beutelkörper eingesiegelt wird.An essential point of the invention is that in this way a precisely fitting bottom or lid and / or shoulder part can be used, which is sealed in the Schlauch¬ bag body.
Gemäß einer Aus führungs form wird das Dehnen bzw. Aufweiten des Schlauchbeutelkör¬ pers reversibel durchgeführt, so daß der Schlauchbeutelkörper nach einem Einführen des Boden- bzw. Deckel- und/oder Schulterteils dicht an diesem bzw. diesen anliegt.According to one embodiment, the stretching or widening of the tubular bag body is carried out in a reversible manner so that the tubular bag body rests tightly against this or these after an insertion of the bottom or lid and / or shoulder part.
Das Maß der Dehnung bzw. Aufweitung des Schlauchbeutelkörpers liegt im Bereich von 100,5 % bis 112,0 %, vorzugsweise im Bereich von 101,0 % bis 107,8 % und besonders bevorzugt im Bereich von 102,0 % bis 105,0 % bezogen auf den Schlauchbeuteldurch¬ messer eines unbelasteten Schlauchbeutels mit einer Normierung auf 100 %. Die Dehnung bzw. Aufweitung des Schlauchbeutelkörpers wird vorteilhafterweise durch¬ geführt, nachdem der Schlauchbeutelkörper aus einem vorzugsweise folienförmigen Schlauchbeutelmaterial, insbesondere Laminat, hergestellt oder als, vorzugsweise naht- loser, Schlauch extrudiert wurde. Die Herstellung des Schlauchbeutelkörpers kann unterThe degree of expansion or expansion of the tubular pouch body is in the range of 100.5% to 112.0%, preferably in the range of 101.0% to 107.8% and particularly preferably in the range of 102.0% to 105.0 % based on the Schlauchbeuteldurch¬ diameter of an unloaded tubular bag with a standardization to 100%. The expansion or widening of the tubular pouch body is advantageously carried out after the tubular pouch body has been produced from a preferably film-shaped tubular pouch material, in particular laminate, or extruded as a, preferably seamless, tube. The preparation of the tubular pouch body can under
Ausbildung einer lap- oder fin-seal-Versiegelung durchgeführt werden, wobei ein ein-, vorzugsweise jedoch beidseitig siegelfähiges Laminat verwendet wird.Forming a lap or fin-seal seal can be carried out, wherein a one, but preferably sealable on both sides laminate is used.
Vorteilhafterweise ist es vorgesehen, für das einzusiegelnde Boden-, Deckel- und/oder Schulterteil sowie in der Siegelschicht dasselbe Material wie für die Herstellung desIt is advantageously provided for the bottom, top and / or shoulder part to be sealed in as well as in the sealing layer the same material as for the production of the
Schlauchbeutelkörpers selbst zu verwenden.To use tubular pouch body itself.
An dieser Stelle sei erwähnt, daß die Dehnung des Laminats, aus dem der Schlauchbeutel¬ körper gebildet wird, auch vor der Herstellung desselben, also bei einer flächigen Folie in der Form eines Flächengebildes, erfolgen kann.It should be mentioned at this point that the stretching of the laminate from which the tubular pouch body is formed can also take place prior to the production thereof, that is to say in the case of a flat film in the form of a fabric.
Gemäß einer Ausführungsform der Erfindung wird die Dehnung bzw. das Aufweiten des Schlauchbeutelkörpers im Einführbereich von Boden-, Deckel- und/oder Schulterteil ko¬ nisch durchgeführt, wobei der innere Durchmesser des Schlauchbeutelkörpers von außen nach innen, d.h. in Richtung Beutelinneres, abnimmt. Die Konizität der Dehnung bzw.According to one embodiment of the invention, the expansion or expansion of the tubular pouch body in the insertion region of bottom, lid and / or shoulder part is performed ko¬ nisch, wherein the inner diameter of the tubular pouch body from outside to inside, i. in the direction of the bag interior, decreases. The conicity of the elongation or
Aufweitung liegt in bezug zu einem nicht aufgeweiteten Schlauchbeutelkörper im Bereich von 1 ,5° bis 17°, vorzugsweise im Bereich vom 5° bis 14,4° und besonders bevorzugt im Bereich von 8,0° bis 12°. Das Maß der Dehnung sowie die Konizität der Dehnung richtet sich nach dem Material und der Dicke des Schlauchbeutelkörpers und — bodens und dessen Rückstellkraft sowie nach der gewünschten Bodenform.Expansion is in relation to a non-expanded tubular pouch body in the range of 1, 5 ° to 17 °, preferably in the range of 5 ° to 14.4 ° and more preferably in the range of 8.0 ° to 12 °. The degree of elongation and the conicity of the elongation depends on the material and the thickness of the tubular pouch body and - floor and its restoring force as well as on the desired floor shape.
Des weiteren ist es erfindungsgemäß vorgesehen, daß der Boden sowie ggf. das Deckel- und/oder das Schulterteil eine konische Form aufweist. In vorteilhafter Weise ist somit einerseits eine leichte Ein fahrbarkeit des Bodens in den gedehnten Schlauchbeutelkörper möglich. Gleiches gilt selbstverständlich für das Deckel und/oder das Schulterteil, die ihrerseits unter Ausnutzung ihrer konischen Form einfach in den gedehnten Schlauch¬ beutelkörper einführbar sind.Furthermore, it is inventively provided that the bottom and possibly the lid and / or the shoulder part has a conical shape. Advantageously, therefore, on the one hand, a slight A driveability of the soil in the stretched tubular bag body is possible. Of course, the same applies to the lid and / or the shoulder part, which in turn can be easily inserted into the stretched tubular bag body by utilizing its conical shape.
Ein weiterer Vorteil der konischen Form des Bodenteils besteht darin, daß die Stand- fläche des Schlauchbeutels auf diese Weise vergrößerbar ist, so daß die Standfestigkeit desAnother advantage of the conical shape of the bottom part is that the stand surface of the tubular bag is enlarged in this way, so that the stability of the
Schlauchbeutels auf äußerst einfache Art erhöht werden kann. Die Konizität des Bodens bzw. Bodenteils sowie des Deckel- und/oder des Schulterteils ist etwas geringer ausgebildet als die Konizität des zughörigen gedehnten bzw. aufgewei¬ teten Schlauchbeutelkörperteils. Eine paßgenaue Einführung des Bodens in den Schlauchbeutelkörper ist somit problemlos möglich, wobei sich der Schlauchbeutelkörper durch die dem Material des Schlauchbeutelkörpers eigene Rückstellkraft optimal an dasTubular bag can be increased in a very simple way. The conicity of the bottom or bottom part as well as the top and / or the shoulder part is slightly less than the conicity of the zughörigen stretched or aufgewei¬ ended tubular bag body part. A precisely fitting introduction of the soil in the tubular pouch body is thus easily possible, wherein the tubular pouch body by the material of the tubular pouch body own restoring force optimally to the
Bodenteil anlegt. Gleiches gilt für die Deckel- und/oder Schulterteile.Floor part applies. The same applies to the lid and / or shoulder parts.
Gemäß einer vorteilhaften Aus führungs form der Erfindung wird bei eingeführtem Boden bzw. Deckel- und/oder Schulterteil an der bezüglich des Schlauchbeutelkörpers innen lie- genden Kante des Bodens, des Deckel- und/oder des Schulterteils, respektive an deren inneren Umfangsrand, eine Dichtsiegelung ausgebildet, mittels derer das Schlauchbeutel¬ innenvolumen gegenüber der Umgebung abgedichtet wird.According to an advantageous embodiment of the invention, when the bottom or lid and / or shoulder part is inserted, a sealing seal is made at the edge of the bottom, the lid and / or the shoulder part lying inside with respect to the tubular pouch body, respectively at its inner peripheral edge formed, by means of which the Schlauchbeutel¬ inner volume is sealed from the environment.
Des weiteren wird zur Verbesserung der Standfestigkeit des Schlauchbeutels an der bezüglich des Schlauchbeutelkörpers außen liegenden Kante des Bodens, also an dessen äußeren Umfangsrand, eine vorzugsweise strukturierte, insbesondere gerillte oder gerif¬ felte, Stützsiegelung ausgebildet.Furthermore, a preferably structured, in particular grooved or gerif¬ felte, support seal is formed to improve the stability of the tubular bag at the outer edge relative to the tubular pouch body of the bottom, ie at its outer peripheral edge.
Eine solche Stützsiegelung kann auch im Bereich des Deckel- und/oder Schulterteils vor- gesehen sein. Hier dient sie einer Festigung des Schlauchbeutelkörpers, so daß dieser, insbesondere bei Verwendung von flexiblen Deckel- und/oder Schulterteilen eine stabile Form ausbildet und mit einer gewissen Festigkeit beibehält. Die Strukturierung der Stütz¬ siegelung kann langgestreckt, beispielsweise gerillt oder geriffelt ausgeführt sein, wobei diese entweder senkrecht, bevorzugt jedoch im wesentlichen in der Ebene des Deckel- bzw. Schulterteils, also horizontal ausgebildet wird. An dieser Stelle sei erwähnt, daß auch andere Strukturierungen, beispielsweise Zick-Zack- oder Wellenprofile im Umfang der Erfindung liegen.Such a support seal can also be provided in the region of the lid and / or shoulder part. Here it serves to consolidate the tubular pouch body, so that this, in particular when using flexible lid and / or shoulder parts forms a stable shape and maintains with a certain strength. The structuring of the Stütz¬ sealing can be elongated, for example, grooved or fluted executed, which is formed either vertically, but preferably substantially in the plane of the lid or shoulder part, ie horizontally. At this point it should be mentioned that other structuring, for example zig-zag or wave profiles are within the scope of the invention.
Um die Maschinenleistung erhöhen zu können, werden die Dicht- und Stützsiegelung(en) im wesentlichen gleichzeitig ausgebildet.In order to increase the machine performance, the sealing and supporting seal (s) are formed substantially simultaneously.
Ein Schneidrand des Bodens bzw. des Deckel- und/oder des Schulterteils wird erfin¬ dungsgemäß, insbesondere unter Ausbildung eines verstärkten Umfangsrandes, innerhalb des Schlauchbeutelkörpers angeordnet, wobei der Schneidrand zwischen Boden-, Deckel- und/oder Schulterteil und Schlauchbeutelkörper eingestülpt wird. Der Schneidrand dient somit als weitere Verstärkung, insbesondere des Bodens des Schlauchbeutelkörpers. In vorteilhafter Weise wird der Schneidrand in den Schlauch hineingezogen bzw. gefaltet und verschwindet optisch in der Überlappung und gegebenenfalls in der Stütznaht von Bodenteil und Schlauchbeutelkörper, wobei eine möglichst steile Flanke des Bodens vorteilhaft ist.A cutting edge of the bottom or of the lid and / or shoulder part is arranged according to the invention, in particular with the formation of a reinforced peripheral edge, inside the tubular pouch body, the cutting edge being inserted between bottom, lid and / or shoulder part and tubular pouch body. The cutting edge thus serves as further reinforcement, in particular of the bottom of the tubular pouch body. Advantageously, the cutting edge is pulled or folded into the tube and visually disappears in the overlap and optionally in the supporting seam of the bottom part and the tubular pouch body, whereby the steepest possible flank of the bottom is advantageous.
Die Ausbildung der Siegelung zwischen Boden-, Deckel- und/oder Schulterteil undThe formation of the seal between bottom, lid and / or shoulder part and
Schlauchbeutelkörper selbst erfolgt mittels Ultraschall, Wärme-Transfer, Induktion > und/oder Heißluft, wobei auch andere Siegelverfahren, wie beispielsweise eine Klebe- siegelung, erfindungsgemäß umfaßt sind.The tubular bag body itself takes place by means of ultrasound, heat transfer, induction and / or hot air, although other sealing methods, such as, for example, an adhesive seal, are also included according to the invention.
Die erfindungsgemäßen Boden-, Deckel- und/oder Schulterteile weisen regelmäßig ge¬ formte, insbesondere mehreckige, runde oder ovale Formen auf und sind, je nach Bedarf, aus einem flexiblen Material oder aus einem formstabilen Material gefertigt. Je nach ge¬ wünschtem späterem Schlauchbeutelinhalt ist vorgesehen, daß sowohl der Schlauchbeu¬ telkörper selbst als auch die Boden-, Deckel- und/oder Schulterteile eine Barriereschicht aufweisen. Diese kann beispielsweise aus SiO2, EVOH oder aus einer Metallfolie beste¬ hen, wobei auch andere gängige Barriereschichtmaterialien denkbar sind.The bottom, top and / or shoulder parts according to the invention have regularly shaped, in particular polygonal, round or oval shapes and are made of a flexible material or of a dimensionally stable material, as required. Depending on the desired later tubular bag content, it is provided that both the tubular bag body itself and the bottom, top and / or shoulder parts have a barrier layer. This can, for example, consist of SiO 2 , EVOH or of a metal foil, although other common barrier layer materials are also conceivable.
Gemäß einer besonders bevorzugten Ausführungsform wird die Siegelung mittels Ultra¬ schall durchgeführt. Bei dieser Variante wird der einzusiegelnde Teil von einer Sonotrode, insbesondere angesaugt und/oder elektrostatisch gehalten und in den Schlauchbeutelkör¬ per eingeführt, wobei ein Amboß außen am Schlauchbeutelkörper angeordnet ist.According to a particularly preferred embodiment, the seal is carried out by means of ultrasound. In this variant, the part to be sealed is held by a sonotrode, in particular aspirated and / or electrostatically, and introduced into the tubular pouch body, wherein an anvil is arranged on the outside of the tubular pouch body.
Der Vorteil dieser Siegelmethode besteht in der Möglichkeit, einen gleichmäßigen Siegel¬ druck über die gesamte Rundung des Schlauchbeutelkörpers auszuüben. Des weiteren können mit einer Siegelung gleichzeitig die Dicht- und die Stütznaht erzeugt werden.The advantage of this sealing method is the possibility of exerting a uniform sealing pressure over the entire rounding of the tubular pouch body. Furthermore, with a seal at the same time the sealing and the support seam can be generated.
Ferner kann beidseitig siegelndes Laminat verwendet werden, wobei der Ultraschall eine optimale Energieübertragung in die Siegelschicht ermöglicht. Wenn, wie bereits erwähnt, der einzusiegelnde Teil von der Sonotrode gehalten wird, kann diese ebenfalls als Trans¬ portwerkzeug für den einzusiegelnden Teil verwendet werden. Darüber hinaus ist die Ul- traschallsiegelung in vorteilhafter Weise dafür geeignet, auch eine bereits gefüllte Packung zu versiegeln, da der Ultraschall lediglich auf den Siegelbereich fokussiert und durch etwaiges Produkt in der Siegelnaht hindurch gesiegelt werden kann. Ein weiterer Vorteil besteht in der Geschwindigkeit, mit der die Ultraschall-Siegelung durchführbar ist, wobei die Maschinenleistung und die Zuverlässigkeit der Siegelung optimiert sind.Furthermore, laminates that seal on both sides can be used, whereby the ultrasound allows optimum energy transfer into the sealing layer. If, as already mentioned, the part to be sealed is held by the sonotrode, this can also be used as a transport tool for the part to be sealed. In addition, the ultrasound sealing is advantageously suitable for also sealing an already filled pack, since the ultrasound can only be focused on the sealing area and sealed by any product in the sealing seam. Another advantage is the speed with which the ultrasonic seal is feasible, with optimized machine performance and seal reliability.
Gemäß einer Weiterbildung der Erfindung ist es möglich, sowohl das Bodenteil als auch das Deckel- und/oder Schulterteil gleichzeitig in einen Schlauchbeutelkörper oder einen bereits mit beispielsweise festem oder pastösern Füllgut befüllten Schlauchbeutel einzu¬ siegeln. Dies kann selbstverständlich auch sukzessive, also nacheinander erfolgen, wobei beispielsweise zunächst das Deckel- und/oder Schulterteil in den Schlauchbeutelkörper eingesiegelt, dieser dann befüllt und nach der Befüllung das zugehörige Bodenteil einge- siegelt wird.According to one embodiment of the invention, it is possible both the bottom part and the lid and / or shoulder part at the same time in a tubular bag body or a To seal in already filled with example solid or pasty filling tube bag. This can of course also be successive, that is, one after the other, wherein, for example, first the lid and / or shoulder part is sealed into the tubular pouch body, this is then filled and after filling the associated bottom part is sealed.
Des weiteren wird die Aufgabe der Erfindung durch einen Schlauchbeutel mit einem Schlauchbeutelkörper und einem eingesiegelten Boden, insbesondere Standboden, sowie gegebenenfalls eingesiegelten Deckel- und/oder Schulterteil gelöst, wobei zumindest der Boden sowie ggf. der Deckel- und/oder das Schulterteil in den Schlauchbeutel eingesetzt ist, wobei der Schlauchbeutel nach einem Verfahren gemäß vorstehender Beschreibung hergestellt ist.Furthermore, the object of the invention is achieved by a tubular bag with a tubular bag body and a sealed bottom, especially bottom, and optionally sealed lid and / or shoulder part, wherein at least the bottom and possibly the lid and / or the shoulder part in the tubular bag is used, wherein the tubular bag is prepared by a method according to the above description.

The tubular bag is formed conically at least in the region of the sealing and supporting seal, and optionally in the region of the lid and / or shoulder part. Furthermore, the support seal has a structuring, in particular grooves, or a corrugation in smooth, zig-zag or wavy profiling.
Des weiteren ist der Schneidrand des Bodenteils bzw. des Deckel- und/oder Schulterteils innerhalb des äußeren Umfangs des Schlauchbeutelkörpers angeordnet.Furthermore, the cutting edge of the bottom part or of the lid and / or shoulder part is arranged within the outer circumference of the tubular pouch body.

In der nachfolgenden Beschreibung werden für gleiche und gleich wirkende Teile diesel¬ ben Bezugsziffern verwendet.Fig. 3 is a schematic representation of a seal according to the invention. In the following description, the same reference numerals are used for the same and like parts.
Fig. 1 zeigt eine schematische Darstellung des erfindungsgemäßen Verfahrens. Es ist der untere Teil eines Schlauchbeutels 10 dargestellt, der aus einem Schlaüchbeutelkörper 20 und einem Boden 30 gebildet wird. Der Boden 30 ist von einer Sonotrode 40 gehalten und weist beidseitig Schneidränder 80 sowie einen Bereich, der über die Sonotrode hin¬ ausragt und als späterer Siegelbereich dient, auf. Seitlich des Schlauchbeutelkörpers 20 ist in der Schnittansicht aus Fig. 1 jeweils ein Amboß 50 erkennbar, der sich rund um denFig. 1 shows a schematic representation of the method according to the invention. It is shown the lower part of a tubular bag 10, which is formed from a Schläüchbeutelkörper 20 and a bottom 30. The bottom 30 is held by a sonotrode 40 and has cutting edges 80 on both sides as well as a region which protrudes beyond the sonotrode and serves as a later sealing region. Side of the tubular pouch body 20 in each case an anvil 50 can be seen in the sectional view of FIG. 1, which is located around the
Schlauchbeutelkörper 20 erstreckt. Der Schlauchbeutelkörper 20 ist in seinem unteren Teil mit einem Faktor von 1 ,028 (= 102,8 %) gegenüber einem ursprünglichen unbelaste¬ ten 100 %-Schlauchbeutelkörper konisch aufgeweitet und weist an seinem unteren Ende einen Innendurchmesser von 51 ,3 mm auf, um das Einführen des Bodens mit einem Außendurchmesser der Boden-Oberkante von 49,9 mm zu erleichtern. Der Schlauchbeu¬ telkörper ist mit einem Winkel von 10° konisch ausgebildet. Der einzusiegelnde Boden liegt auf einer vorgeformten Sonotrode 40 mit einer Konizität von 5° auf, so daß die Sei¬ tenflanke des Bodens 30 beim Einführen in den Schlauchbeutelkörper an die Konizität des Schlauchbeutelkörpers 20 angepaßt wird. Der von der Sonotrode 40 gehaltene Boden 30 mit seiner linken seitlichen Flanke und dem Schneidrand 80 ist in Fig. 2 besonders gut zu- erkennen. Fig. 2 stellt eine vergrößerte Ansicht des eingekreisten Abschnitts aus Fig. 1 dar. Zur Herstellung des Schlauchbeutels 10 wird die Sonotrode 40 mit dem auf dieser aufliegenden Boden 30 in den konisch aufgeweiteten Schlauchbeutelkörper 20 eingescho¬ ben, so daß sich auch der Schneidrand 80 gerade noch im Schlauch befindet. Der Schneidrand 80 wird sodann entweder auch in den Schlauchbeutelkörper 20 eingeführt oder so umgefaltet bzw. umgestülpt, daß er zwischen dem unteren Rand des Schlauch¬ beutelkörpers 20 und dem Boden 30 zu liegen kommt.Tubular bag body 20 extends. The tubular pouch body 20 is conically widened in its lower part by a factor of 1.028 (= 102.8%) compared with an original unbuffered 100% tubular pouch body and has an inner diameter of 51.3 mm at its lower end to facilitate the insertion of the soil with an outside diameter of the bottom top edge of 49.9 mm. The Schlauchbeu¬ telkörper is conically formed at an angle of 10 °. The bottom to be sealed lies on a preformed sonotrode 40 with a conicity of 5 °, so that the side edge of the bottom 30 is adapted to the conicity of the tubular pouch body 20 when it is introduced into the tubular pouch body. The bottom 30 held by the sonotrode 40 with its left lateral flank and the cutting edge 80 can be seen particularly well in FIG. 2 shows an enlarged view of the circled portion of FIG. 1. To produce the tubular bag 10, the sonotrode 40 is pushed into the conically widened tubular bag body 20 with the bottom 30 resting thereon so that the cutting edge 80 is also straight still in the hose. The cutting edge 80 is then either inserted into the tubular bag body 20 or folded over or everted so that it comes to rest between the lower edge of the tubular bag body 20 and the bottom 30.
In Fig. 3 ist ein Boden-Siegelbereich in Detailansicht dargestellt, wobei schematisch eine Dichtsiegelung 60 sowie eine Stützsiegelung 70 angedeutet sind, die den Schlauchbeutel¬ körper in dichtender bzw. stützender Weise mit dem Boden 30 verbinden. An der Ober¬ kante des Bodens 30 ist eine 1 mm breite Dichtsiegelung ausgebildet. Unterhalb der Dichtsiegelung 60 ist eine Stützsiegelung dargestellt, die ca. 3 mm hoch ausgebildet ist. Der Schneidrand 80 kann vor Ausbildung der Stützsiegelung umgefaltet und in den Schlauch hineingezogen werden (nicht gezeigt) und bis zu einem Bereich von ca. 0,5 mm in der Überlappung zwischen Schlauchbeutelkörper 20 und Boden 30 verschwinden. An dieser Stelle sei darauf hingewiesen, daß alle oben beschriebenen Teile für sich alleine gesehen und in jeder Kombination, insbesondere die in den Zeichnungen dargestellten Details, als erfindungswesentlich beansprucht werden. Abänderungen hiervon sind dem Fachmann geläufig.FIG. 3 shows a detail of a bottom sealing region, wherein a sealing seal 60 and a support seal 70 are schematically indicated, which connect the tubular pouch body to the bottom 30 in a sealing or supporting manner. At the Ober¬ edge of the bottom 30, a 1 mm wide sealing seal is formed. Below the seal seal 60, a support seal is shown, which is about 3 mm high. The cutting edge 80 may be folded over before formation of the support seal and drawn into the tube (not shown) and disappear to a range of about 0.5 mm in the overlap between the tubular pouch body 20 and the bottom 30. It should be noted at this point that all the above-described parts are considered to be alone and in every combination, in particular the details shown in the drawings, claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
