Description

Die Erfindung betrifft eine Schlauchbeutelpackung aus Flachfolie aus Kunststoff o. dgl. verschweiß- und/oder verklebbarem Werkstoff, mit einer schlauchbildenden Längsnaht in einer der beiden einander gegenüberliegenden Beutelwände, einem boden- und nach Befüllung kopfseitig von je einer Querschweißnaht begrenzten Füllraum sowie einem füllgutfreien oberen Randbereich, der unterseitig von der Kopfnaht des Füllraums und oberseitig von einer oberen Abschluß-Querschweißnaht der Packung begrenzt sowie mit einem sich durch die einander gegenüberliegenden Beutelwände erstreckenden, durch Stanzen oder Einschneiden.gebildeten Griffloch in der Längsmittelebene der Packung versehen ist.The invention relates to a tubular bag pack made of flat film made of plastic or the like.Weldable and / or gluable material, with a tube-forming longitudinal seam in one of the two opposing pouch walls, a bottom and after filling head-side, each with a cross-weld seam, a filling space limited by a filler and an upper free of filling Edge area, which is delimited on the underside by the top seam of the filling space and on the top side by an upper final cross-weld seam of the pack and is provided with a grip hole in the longitudinal median plane of the pack which extends through the opposing pouch walls and is formed by punching or cutting.

Schlauchbeutelpackungen dieser Art werden in der Regel von Flachbahnen aus Kunststoffolie gebildet, die über eine Formatschulter zu einem Schlauch gefaltet und dabei mit einer schlauchbildenden Längsnaht versehen werden. Der so gebildete Schlauch wird durch Quernähte unterteilt und während der Herstellung der Schlauchbeutelpackungen portionsweise mit z. B. riesel- oder schüttfähigem Füllgut wie Streusalz befüllt, woraufhin der Füllraum durch eine weitere Quernaht oberseitig abgeschlossen und der füllgutfreie obere Randbereich der Schlauchbeutelpackung mit der oberen Abschlußquernaht gebildet wird, in dem zugleich durch einen Schneid- oder Stanzvorgang das Griffloch zum Tragen der in dieser Weise hergestellten und gleichzeitig befüllten Packung erzeugt wird.Tubular bag packs of this type are generally formed from flat sheets of plastic film, which are folded over a format shoulder to form a tube and are thereby provided with a tube-forming longitudinal seam. The tube thus formed is divided by transverse seams and in portions with z. B. filled or pourable filling material such as road salt, whereupon the filling space is closed at the top by a further transverse seam and the filling-free upper edge region of the tubular bag pack is formed with the upper final transverse seam, in which the grip hole for carrying the same is carried out by a cutting or punching process Way manufactured and at the same time filled pack is generated.

Es hat sich bei bekannten derartigen Schlauchbeutelpackungen gezeigt, daß das Griffloch schon bei mäßigen Verpackungsgewichten leicht ausreißt, wodurch die herstellerseitig gegebene Traghilfe verlorengeht. Einer Erhöhung der Festigkeit der Beutelwände durch eine dickere Flachfolie als Ausgangswerkstoff stehen hierbei in erster Linie Kostengründe entgegen, da solche Schlauchbeutelpackungen Einwegverpackungen sind, die mit einem .Mindestmaß an Materialverbrauch herstellbar sein sollen. Im Zusammenhang mit Leerpackungen in Form von Grifflochbeuteln oder -tragetaschen, wie sie insbesondere in Kaufhäusern und Supermärkten den Kunden zum Verpacken der eingekauften Waren zur Verfügung gestellt werden, ist es zwar schon bekannt geworden, nur den Grifflochbereich der Beutelwände zu verstärken, jedoch lassen sich die dabei Anwendung findenden Herstellungstechniken und die daraus resultierenden Ausgestaltungen nicht ohne weiteres auf Schlauchbeutelpackungen der eingangs angegebenen Art übertragen, bei denen der Füllvorgang der Packung in den Herstellungsprozeß der Packung integriert ist.It has been shown in known tubular bag packs of this type that the grip hole tears easily even with moderate packaging weights, as a result of which the carrying aid provided by the manufacturer is lost. An increase in the strength of the bag walls by means of a thicker flat film as the starting material is primarily due to cost reasons, since such tubular bag packs are disposable packagings which should be able to be produced with a minimum amount of material consumption. In connection with empty packs in the form of grip hole bags or carrier bags, such as are made available to customers in particular in department stores and supermarkets for packaging the purchased goods, it has already become known to reinforce only the grip hole area of the bag walls, but they can be the manufacturing techniques used and the resulting configurations are not readily transferred to tubular bag packs of the type specified at the outset, in which the filling process of the pack is integrated into the manufacturing process of the pack.

Die der Erfindung zugrundeliegende Aufgabe besteht somit darin, eine Schlauchbeutelpackung der angegebenen Art zu schaffen, deren Griffloch im füllgutfreien oberen Randbereich mit denkbar geringem Materialaufwand soweit verstärkt ist, daß ein Ausreißen des Grifflochs normalerweise verhindert ist.The object on which the invention is based is therefore to create a tubular bag pack of the type specified, the grip hole of which is reinforced in the upper edge region free of filling material with the least possible expenditure of material to such an extent that tearing out of the grip hole is normally prevented.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Griffloch mit einem seine Kontur umgebenden, mit der längsnahtfreien Beutelwand verbundenen, seinerseits ein konturengleiches Griffloch.aufweisenden Verstärkungsstreifen versehen ist, der seinerseits aus Kunststoffolie o. dgl. verschweiß- und/oder verklebbarem Werkstoff besteht.This object is achieved according to the invention is that the grip hole is connected to a surrounding its contour, with the longitudinal seam-free bag wall, for its part a contour identical G riffloch.aufweisenden reinforcing strip is provided, which in turn o of plastic film. The like weldability. And / or bondable material consists.

• Eine in di.eser Weise ausgebildete Schlauchbeutelpackung hat trotz des geringen Materialverbrauchs für den Griffloch-Verstärkungsstreifen, der nur der längsnahtfreien Beutelwand zugeordnet zu sein braucht, ein hohes Maß an Packungsfestigkeit im Grifflochbereich. Obwohl grundsätzlich zur Grifflochverstärkung beiden Beutelwänden je ein Verstärkungsstreifen zugeordnet werden kann, ist ein solcher Verstärkungsstreifen in der die schlauchbildende Längsnaht enthaltenden Beutelwand entbehrlich, da hier die Längsnaht ihrerseits eine versteifende Wirkung auf die Beutelwand ausübt..Wie Versuche gezeigt haben, ist durch die erfindungsgemäße Ausgestaltung eine gegenüber herkömmlichen Schlauchbeutelpackungen um das Zehn- bis Fünfzehnfache höhere Festig- keit der Packung im Grifflochbereich erzielt worden. Dabei ist die.weitere Möglichkeit gegeben, die als Ausgangsmaterial zur Herstellung der Schlauchbeutelpackung dienende Flachbahn aus insbesondere Kunststoffolie in ihrer Dicke zu reduzieren, ohne daß damit eine wesentliche Herabsetzung der Packungsfestigkeit im Grifflochbereich einhergeht. Der durch den Verstärkungsstreifen bedingte Material-Mehrverbrauch kann auf diese Weise zumindest ausgeglichen werden.• A tubular bag pack designed in this way has a high degree of packing strength in the handle hole area, despite the low material consumption for the grip hole reinforcement strip, which only needs to be assigned to the longitudinally seam-free bag wall. Although in principle a reinforcement strip can be assigned to both pouch walls to reinforce the grip hole, such a reinforcement strip in the pouch wall containing the longitudinal seam forming the tube is dispensable, since here the longitudinal seam in turn exerts a stiffening effect on the pouch wall compared with conventional tubular bag packages to ten to fifteen times higher F estig- been achieved ness of the pack in the handle hole portion. There is a further possibility to reduce the thickness of the flat web, which is used as the starting material for the production of the tubular pouch pack, in particular from plastic film, without this resulting in a significant reduction in the pack strength in the grip hole area. The additional material consumption caused by the reinforcement strip can at least be compensated in this way.

Es versteht sich im übrigen, daß für den Verstärkungsstreifen die verschiedensten geeigneten Materialien, wie z. B. gleiches, dickeres oder dünneres, Material wie das der Beutelwände, z. B. Polyäthylen, oder unterschiedliches, festeres und dafür dünneres, Material wie das der Beutelwände, z. B. Bändchengewebe, Anwendung finden können.It goes without saying that a variety of suitable materials such as. B. the same, thicker or thinner material as that of the bag walls, for. B. polyethylene, or different, firmer and thinner, material such as that of the bag walls, for. B. ribbon fabric, can find application.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachstehenden Beschreibung in Verbindung mit der Zeichnung, deren Fig.. 1 bis 4 je ein Ausführungsbeispiel des Gegenstands der Erfindung in einer schematischen. Vorderansicht. veranschaulichen.Further features and advantages of the invention will become apparent from the claims and the following description in conjunction with the drawing, the Fig .. 1 to 4 each Embodiment of the object of the invention in a schematic. Front view. illustrate.

Die Zeichnung zeigt eine als Ganzes mit 1 bezeichnete Schlauchbeutelpackung aus Kunststoff-Flachfolie mit einer schlauchbildenden Längsnaht 2 in einer der.beiden einander gegenüberliegenden Beutelwände , von denen in der Zeichnung nur die längsnahtfreie Beutelwand 3 zur Darstellung kommt. Die Längsnaht 2 ist bei dem dargestellten Beispiel eine Schweißnaht. An ihrem unteren Ende ist die Schlauchbeutelpackung 1 von einer Querschweißnaht 4 abgeschlossen. Unterhalb der Querschweißnaht 4 befindet sich eine Trennkante 5, die beim Abtrennen der Schlauchbeutelpackung 1 vom Beutelschlauch entstanden ist. Die Querschweißnaht 4 bildet eine Bodennaht zur unteren Begrenzung eines Füllraums 6, der nach dem Befüllen mit insbesondere schütt- oder rieselfähigem Füllgut kopfseitig durch eine weitere Querschweißnaht 7 abgeschlossen und begrenzt wird.The drawing shows a tubular bag pack made of flat plastic film, designated as a whole by 1, with a tube-forming longitudinal seam 2 in one of the two opposing bag walls, of which only the bag wall 3 without longitudinal seams is shown in the drawing. The longitudinal seam 2 is a weld seam in the example shown. At its lower end, the tubular bag pack 1 is closed by a cross weld 4. Below the cross weld 4 there is a separating edge 5 which was created when the tubular bag pack 1 was separated from the bag tube. The transverse weld seam 4 forms a bottom seam for the lower boundary of a filling space 6, which is closed and delimited on the head side by a further transverse weld seam 7 after filling with, in particular, pourable or pourable filling material.

Die Schlauchbeutelpackung 1 umfaßt ferner einen füllgutfreien oberen.Randbereich 8, der unterseitig von der Kopfnaht 7 des Füllraums 6 und oberseitig von einer oberen Abschluß-Querschweißnaht 9 begrenzt ist. Gestrichelt ist bei 10 eine Trennlinie dargestellt, die beim Abtrennen der gefüllten Schlauchbeutelpackung 1 vom sich bei der zeichnerischen Darstellung nach oben hin fortsetzenden Beutelschlauch eine obere Trennkante der Schlauchbeutelpackung 1 und eine untere Trennkante einer nächstoberen Schlauchbeutelpackung definiert. Das Anbringen der oberen Abschlußnaht 9 der Schlauchbeutelpackung 1 kann in an sich bekannter Weise gleichzeitig mit dem Anbringen der unteren Bodennaht 4 der nächstoberen Schlauchbeutelpackung und dem Abtrennen der befüllten Schlauchbeutelpackung 1 entlang der Trennlinie 10 erfolgen.The tubular bag pack 1 further comprises an upper edge region 8 which is free of filling material and which is delimited on the underside by the top seam 7 of the filling chamber 6 and on the top side by an upper end transverse weld 9. A dashed line at 10 shows a dividing line which, when the filled tubular bag pack 1 is separated from the bag hose which continues upwards in the drawing, defines an upper separating edge of the tubular bag pack 1 and a lower separating edge of a next upper tubular bag pack. The attachment of the upper end seam 9 of the tubular bag pack 1 can take place in a manner known per se simultaneously with the attachment of the lower bottom seam 4 of the next upper tubular bag pack and the separation of the filled tubular bag pack 1 along the dividing line 10.

Der füllgutfre£e obere Randbereich 8 ist als Tragmöglichkeit für die 'Schlauchbeutelpackung 1 mit einem Griffloch 11, bei dem dargestellten Ausführungsbeispiel in Form eines bogenförmigen Stanzschnittes, versehen, das sich durch die einander gegenüberliegenden Beutelwände und durch einen Verstärkungsstreifen 12 hindurcherstreckt. Der Verstärkungsstreifen 12, der wie die Schlauchbeutelpackung 1 aus verschweiß- und/oder verklebbarem Werkstoff wie Kunststoffolie, z. B. Polyäthylenfolie, besteht, ist in der Längsmittelebene der Packung 1 symmetrisch zu beiden Seiten der Längsnaht 2 angeordnet, wobei er die Kontur des Grifflochs .11 allseits umgibt und mit der angrenzenden längsnahtfreien Beutelwand 3 verbunden ist-.The füllgutfre £ e upper edge portion 8 is provided as a supporting way for the 'bag package 1 with a finger hole 11, in the illustrated embodiment in the form of an arcuate punch cut, which extends through the opposite bag walls and by a reinforcing strip 12th The reinforcing strip 12, which, like the tubular bag pack 1, is made of weldable and / or gluable material such as plastic film, for. B. polyethylene film, is arranged in the longitudinal center plane of the pack 1 symmetrically on both sides of the longitudinal seam 2, wherein it surrounds the contour of the grip hole .11 on all sides and is connected to the adjacent longitudinal seam-free bag wall 3 -.

Während bei sämtlichen dargestellten Ausführungsbeispielen die Breite der Verstärkungsstreifen gleich ge - wählt ist und in Querrichtung der Packung 1 gemessen der halben Packungsbreite entspricht, ist die Länge der Verstärkungsstreifen unterschiedlich gewählt.While the width of the reinforcement strips is selected to be the same in all of the illustrated exemplary embodiments and, measured in the transverse direction of the pack 1, corresponds to half the width of the pack, the length of the reinforcement strips is selected differently.

Bei dem Ausführungsbeispiel nach Fig.1 ist der Verstärkungsstreifen nach einem besonders einfachen Herstellungsverfahren von einem gemeinsam mit der die Packung 1 bildenden Folie die Vorrichtung zum Herstellen und Füllen der Packung durchlaufenden Verstärkungsband gebildet und besitzt die gleiche Länge wie die Packung 1. Dabei ist der Verstärkungsstreifen 12 sowohl in der oberen Abschlußnaht 9 als auch in der Kopfnaht 7 und der Bodennaht 4 des Füllraums 6 der Packung 1 mit eingeschweißt und auf diese Weise mit der angrenzenden, längsnahtfreien Beutelwand 3 verbunden, wobei die Abtrennung der Verstärkungsstreifen zusammen mit der Abtrennung der jeweiligen Packung vom Beutelschlauch erfolgt. Der Verstärkungsstreifen 12 kann nach einer nicht gezeigten Ab-wandlung des Ausführungsbeispiels nach Fig. 1 soweit verkürzt sein, daß er nur in die obere Abschlußschweißnaht 9 und in die Kopfnaht 7 des Füllraums, gegenüber dieser zum Füllraum 6 hin um ein gewisses Maß vorspringend, eingeschweißt ist.In the exemplary embodiment according to FIG. 1, the reinforcement strip is formed by a particularly simple manufacturing process from a reinforcement tape that passes through the film forming the pack 1 and the device for producing and filling the pack and has the same length as the pack 1 . The reinforcement strip 12 is welded in both the top A seam 9 and in the top seam 7 and the bottom seam 4 of the filling space 6 of the pack 1 and in this way connected to the adjacent, longitudinal seam-free bag wall 3, the separation of the reinforcement strips together with the respective pack is separated from the bag tube. The reinforcing strip 12 can be used as far as possible after an A b conversion of the exemplary embodiment according to FIG. 1, not shown can be shortened that it is only welded into the upper final weld 9 and into the top seam 7 of the filling space, projecting to a certain extent from the filling space 6.

Im Bereich zwischen der oberen Abschlußnaht 9 der Packung 1 und der Kopfnaht 7 sowie, entsprechend dem Ausführungsbeispiel nach Fig. 1, der Bodennaht 4 des Füllraums 6 hat der Verstärkungsstreifen 12 keine Verbindung mit der Beutelwand 3, sondern verläuft lose an dieser entlang. Die Krafteinleitung in den Verstärkungsstreifen 12 beim Tragen der Packung 1 erfolgt somit lediglich über die Kopfschweißnaht 7 und ggf. die Bodennaht 4 der Packung 1, die den Füllraum 6 begrenzen.In the area between the upper end seam 9 of the pack 1 and the head seam 7 and, according to the exemplary embodiment according to FIG. 1, the bottom seam 4 of the filling space 6, the reinforcement strip 12 has no connection to the bag wall 3, but runs loosely along it. The force is introduced into the reinforcement strip 12 when the pack 1 is carried, thus only via the head weld 7 and possibly the bottom seam 4 of the pack 1, which delimit the filling space 6.

Das Ausführungsbeispiel nach Fig. 2 zeigt eine Anordnung mit einem Verstärkungsstreifen 13, der zwar am füllgutfreien oberen Randbereich 8 der Packung 1 zum Füllraum 6 hin vorspringt, jedoch mit geringem Abstand unterhalb der Kopfnaht 7 des Füllraums 6 endet, in die er mit eingeschweißt sein kann. Das obere Ende des Verstärkungsstreifens 13 endet mit geringem Abstand unterhalb der oberen Abschlußnaht 9 der Packung 1, wobei zur Fixierung des Verstärkungsstreifens 13 im Bereich zwischen den Nähten 7 und 9 flächige Verbindungen, insbesondere Verschweißungen, zwischen dem Verstärkungsstreifen 13 und der längsnahtfreien Beutelwand 3 vorgenommen sein können.The exemplary embodiment according to FIG. 2 shows an arrangement with a reinforcement strip 13, which projects from the filling-free upper edge area 8 of the pack 1 towards the filling space 6, but ends at a short distance below the top seam 7 of the filling space 6, into which it can be welded . The upper end of the reinforcement strip 13 ends at a short distance below the upper end seam 9 of the pack 1, with flat connections, in particular welds, between the reinforcement strip 13 and the longitudinally seam-free bag wall 3 being made to fix the reinforcement strip 13 in the area between the seams 7 and 9 can.

Bei dem Ausführungsbeispiel nach Fig. 3 ist ein Verstärkungsstreifen 14 vorgesehen, der gegenüber dem Aus- führungsbeispiel nach Fig. 2 in Packungslängsrichtung noch weiter verkürzt und auf einen Bereich zwischen der oberen Abschlußnaht 9 und der Kopfnaht 7 des Füllraums 6 begrenzt ist. Die Verbindung des Verstärkungsstreifens 14 mit der angrenzenden längsnahtfreien Beutel wand 3 ist hierbei über flächige Verbindungen, nämlich Verschweißungen oder.Verklebungen, vorgenommen, durch die die Krafteinleitung in den Verstärkungsstreifen beim Tragen der Packung erfolgt.In the embodiment according to FIG. 3, a reinforcing strip 14 is provided, which is opposite the initial EADERSHIP Example F according to FIG. Further shortened in package longitudinal direction 2 and limited to a range between the upper closing seam 9 and the head seam 7 of the filling space. 6 The connection of the reinforcement strip 14 with the adjacent longitudinal seam-free bag wall 3 is here over flat connections, namely Welding or.bondings, by which the force is introduced into the reinforcement strip when the pack is carried.

Während bei den Ausführungsbeispielen nach den Fig. 1 bis 3 die Verstärkungsstreifen 12 bis 14 jeweils auf der Innenseite der längsnahtfreien Beutelwand 3 angeordnet sind,'versteht sich, daß grundsätzlich auch eine Anordnung des jeweiligen Verstärkungsstreifens auf der Außenseite der Beutelwand 3 vorgenommen werden kann, wie dies bei dem Ausführungsbeispiel nach Fig. 4 bei einem Verstärkungsstreifen 15 veranschaulicht ist, der im übrigen analog dem Verstärkungsstreifen 14 nach Fig. 3 durch flächige Verklebungen oder Verschweißungen mit der längsnahtfreien Beutelwand 3 verbunden ist. Die Anordnung der Verstärkungsstreifen auf der Innenseite der Beutelwand 3 wird jedoch insbesondere bei einem nur in den Querschweißnähten mit der Beutelwand.verbundenen Verstärkungsstreifen.bevorzugt, weil dadurch ein versehentliches Beschädigen oder Abreißen des Verstärkungsstreifens durch äußere Einflüsse verhindert ist.1 to 3, the reinforcement strips 12 to 14 are each arranged on the inside of the longitudinally free bag wall 3, 'it goes without saying that, in principle, the respective reinforcement strip can also be arranged on the outside of the bag wall 3, such as this is illustrated in the embodiment according to FIG. 4 with a reinforcement strip 15, which is otherwise connected to the reinforcement strip 14 according to FIG. 3 by means of two-dimensional gluing or welding to the bag wall 3 without longitudinal seams. The arrangement of the reinforcement strips on the inside of the bag wall 3 is preferred, in particular, in the case of a reinforcement strip which is connected to the bag wall only in the transverse weld seams, because this prevents accidental damage or tearing of the reinforcement strip by external influences.
