Definitions
- the invention relates to a tubular bag package 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 bag walls, a bottom and, after filling, a filling space which is delimited on the head side by a transverse weld seam and an upper that is free of filling material 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 has a grip hole which extends through the opposing pouch walls and is formed by punching or cutting in the longitudinal median plane of the pack and has a contour surrounding, for its part having a contour-like grip hole reinforcing strips made of plastic film or the like. Weldable and / or glued material is provided, the reinforcing strip having a length which is equal to the length of the pack and in the upper end the seam of the pack as well as in the top seam and in the bottom seam of the filling space.
- Such tubular bag packs 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, during the manufacture of the tubular bag packs, in portions with e.g. Free-flowing or pourable filling material such as road salt is filled, whereupon the filling space is closed on the upper side by a further transverse seam and the filling-free upper edge region of the tubular bag pack is formed with the upper closing transverse seam, in which the grip hole for carrying the material produced in this way is simultaneously cut or punched and at the same time filled pack is generated.
- Free-flowing or pourable filling material such as road salt
- the reinforcement strip reinforces only the grip hole area of the tubular bag pack.
- the reinforcement strip is formed by a layer of the double layer, which represents the tube-forming longitudinal overlap seam of the bag package.
- the bag pack is stiffened only in its bag wall containing the longitudinal seam, and the reinforcement strip always has the same material thickness and properties as the tubular bag pack. It is thus not possible in the known design to choose the thickness and material properties of the reinforcement strip independently of the material of the bag walls.
- the object on which the invention is based is therefore to create a tubular bag pack of the type specified at the outset, the grip hole of which is reinforced in the fill-free upper edge area with a conceivably low amount of material for the tubular bag pack overall, so that tearing out of the grip hole when carrying the filled bag pack is normally prevented .
- the longitudinally seam-free bag wall is provided with the reinforcement strip and in that the reinforcement strip is formed by a separate reinforcement band, which in the area between the upper end seam of the pack and the top seam and the bottom seam of the filling space is connected to the longitudinal seam-free region Bag wall runs.
- a tubular bag pack designed in this way provides a high degree of load-bearing strength of the bag pack in the grip hole area with low material consumption for the reinforcement strip, which according to the invention is assigned to the longitudinally seam-free bag wall, in conjunction with the tube-forming longitudinal seam contained in the other bag wall, which in turn has a stiffening effect on the bag wall Bag pack exercises. Furthermore, the fact that the reinforcement strip according to the invention is formed by a separate reinforcement band allows the thickness and the material properties of the reinforcement strip to be chosen as desired, depending on the requirements placed on the load-bearing capacity of the pack.
- the invention thus creates a particularly advantageous, on the one hand material-saving and on the other hand high-strength tubular bag pack which, as tests have shown, has a ten to 15 times higher strength in the grip hole area than conventional tubular bag packs.
- suitable materials can be used for the reinforcement strip, such as, for example, the same, thicker or thinner material as that of the bag walls, for example polyethylene, or different, stronger and therefore thinner material such as that of the bag walls, for example ribbon fabric.
- 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.
- the tubular bag pack 1 is closed by a transverse weld 4.
- the cross-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 cross-weld seam 7 after filling with, in particular, pourable or pourable filling material.
- the tubular bag pack 1 further comprises an upper edge region 8 which is free of filling 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 seam 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 upper end seam 9 of the tubular bag pack 1 can be attached 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.
- the filling-free upper edge area 8 is provided as a carrying option for the tubular bag pack 1 with a grip hole 11, in the illustrated embodiment in the form of an arcuate die cut, which extends through the opposing bag walls and through a reinforcing strip 12.
- the reinforcement strip 12 which, like the tubular bag pack 1, is made of weldable and / or gluable material such as plastic film, e.g. Polyethylene film, is arranged in the longitudinal center plane of the package 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.
- the width of the reinforcement strip 12 measured in the transverse direction of the package 1 is selected to be approximately half the package width.
- the reinforcement strip 12 is formed according to a particularly simple manufacturing method from a reinforcement band passing through the device for producing and filling the pack together with the film forming the pack 1 and has the same length as the pack 1.
- the reinforcement strip 12 is both in the upper end seam 9 as well as 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 being carried out together with the separation of the respective pack from the bag tube.
- the reinforcement strip 12 In the area between the upper end seam 9 of the pack 1 and the top seam 7 and 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 reinforcing strip 12 when the pack 1 is carried, thus only via the head weld 7 and the bottom seam 4 of the pack 1, which delimit the filling space 6.
- the reinforcing strip 12 is advantageously arranged in the interior of the bag because this prevents accidental damage or tearing off of the reinforcing strip 12 due to external influences.

Description
Die Erfindung betrifft eine Schlauchbeutelpakkung aus Flachfolie aus Kunststoff od. dgl. verschweiss- und/oder verklebbarem Werkstoff, mit einer schlauchbildenden Längsnaht in einer der beiden einander gegenüberliegenden Beutelwände, einem boden- und nach Befüllen 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 ist, sowie ein sich durch die einander gegenüberliegenden Beutelwände erstreckendes, durch Stanzen oder Einschneiden in der Längsmittelebene der Packung gebildetes Griffloch aufweist, das mit einem seine Kontur umgebenden, seinerseits ein konturengleiches Griffloch aufweisenden Verstärkungsstreifen aus Kunststoffolie od. dgl. verschweiss- und/oder verklebbarem Werkstoff versehen ist, wobei der Verstärkungsstreifen eine Länge besitzt, die gleich der Länge der Packung ist und in der oberen Abschlussnaht der Packung sowie in der Kopfnaht und in der Bodennaht des Füllraums miteingeschweisst ist.The invention relates to a tubular bag package 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 bag walls, a bottom and, after filling, a filling space which is delimited on the head side by a transverse weld seam and an upper that is free of filling material 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 has a grip hole which extends through the opposing pouch walls and is formed by punching or cutting in the longitudinal median plane of the pack and has a contour surrounding, for its part having a contour-like grip hole reinforcing strips made of plastic film or the like. Weldable and / or glued material is provided, the reinforcing strip having a length which is equal to the length of the pack and in the upper end the seam of the pack as well as in the top seam and in the bottom seam of the filling space.
Derartige Schlauchbeutelpackungen 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.Such tubular bag packs 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, during the manufacture of the tubular bag packs, in portions with e.g. Free-flowing or pourable filling material such as road salt is filled, whereupon the filling space is closed on the upper side by a further transverse seam and the filling-free upper edge region of the tubular bag pack is formed with the upper closing transverse seam, in which the grip hole for carrying the material produced in this way is simultaneously cut or punched 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 Traghilfeverlorengeht. 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 Mindestmassan Materialverbrauch herstellbar sein sollen.It has been shown in known tubular bag packs of this type that the grip hole easily tears out 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 of material consumption.
Um hier Abhilfe zu schaffen, ist bei einer bekannten Schlauchbeutelpackung der eingangs angegebenen Art (DE-A-1953953) durch den Verstärkungsstreifen eine Verstärkung nur des Grifflochbereichs der Schlauchbeutelpackung vorgenommen. Der Verstärkungsstreifen ist dabei von einer Lage der Doppellage gebildet, die die schlauchbildende Überlappungslängsnaht der Beutelpackung darstellt. Hierdurch ist die Beutelpackung nur in ihrer die Längsnaht enthaltenden Beutelwand versteift, und der Verstärkungsstreifen hat stets die gleiche Materialdicke und -beschaffenheit wie die Schlauchbeutelpackung. Es ist somit bei der bekannten Ausgestaltung nicht möglich, die Dicke und Materialbeschaffenheit des Verstärkungsstreifens unabhängig von dem Material der Beutelwändezu wählen. Für die Tragfestigkeit der bekannten Schlauchbeutelpackung ungünstig erweist sich ferner die Tatsache, dass der Verstärkungsstreifen als Teil der schlauchbildenden Längsnaht der Beutelpackung über seine gesamte Länge fest mit der Beutelwand verbunden ist. Hierdurch erfolgt die Krafteinleitung in den Verstärkungsstreifen beim Tragen der Packung über die den Verstärkungsstreifen enthaltende Beutelwand, so dass diese entsprechend beansprucht ist und einer Reduzierung der Dicke des Wandmaterials der Beutelpackung insgesamt dadurch enge Grenzen gesetzt sind.In order to remedy this situation, in a known tubular bag pack of the type specified at the outset (DE-A-1953953), the reinforcement strip reinforces only the grip hole area of the tubular bag pack. The reinforcement strip is formed by a layer of the double layer, which represents the tube-forming longitudinal overlap seam of the bag package. As a result, the bag pack is stiffened only in its bag wall containing the longitudinal seam, and the reinforcement strip always has the same material thickness and properties as the tubular bag pack. It is thus not possible in the known design to choose the thickness and material properties of the reinforcement strip independently of the material of the bag walls. The fact that the reinforcement strip as part of the tube-forming longitudinal seam of the bag package is firmly connected to the bag wall over its entire length proves unfavorable for the load-bearing capacity of the known tubular bag package. As a result, the force is introduced into the reinforcement strip when the pack is carried over the bag wall containing the reinforcement strip, so that it is correspondingly stressed and, as a result, there are strict limits to reducing the thickness of the wall material of the bag pack.
Die der Erfindung zugrundeliegende Aufgabe besteht somit darin, eine Schlauchbeutelpackung der eingangs angegebenen Art zu schaffen, deren Griffloch im füllgutfreien oberen Randbereich mit denkbar geringem Materialaufwand für die Schlauchbeutelpackung insgesamt so weit verstärkt ist, dass ein Ausreissen des Grifflochs beim Tragen der gefüllten Beutelpackung normalerweise verhindert ist.The object on which the invention is based is therefore to create a tubular bag pack of the type specified at the outset, the grip hole of which is reinforced in the fill-free upper edge area with a conceivably low amount of material for the tubular bag pack overall, so that tearing out of the grip hole when carrying the filled bag pack is normally prevented .
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die längsnahtfreie Beutelwand mit dem Verstärkungsstreifen versehen ist und dass der Verstärkungsstreifen von einem gesonderten Verstärkungsband gebildet ist, das im Bereich zwischen der oberen Abschlussnaht der Packung und der Kopfnaht sowie der Bodennaht des Füllraums verbindungsfrei mit der längsnahtfreien Beutelwand verläuft.This object is achieved according to the invention in that the longitudinally seam-free bag wall is provided with the reinforcement strip and in that the reinforcement strip is formed by a separate reinforcement band, which in the area between the upper end seam of the pack and the top seam and the bottom seam of the filling space is connected to the longitudinal seam-free region Bag wall runs.
Eine in dieser Weise ausgebildete Schlauchbeutelpackung erbringt ein hohes Mass an Tragfestigkeitder Beutelpackung im Grifflochbereich bei geringem Materialverbrauch für den nach der Erfindung der längsnahtfreien Beutelwand zugeordneten Verstärkungsstreifen in Verbindung mit der in der anderen Beutelwand enthaltenen schlauchbildenden Längsnaht, die ihrerseits in dieser Beutelwand eine versteifende Wirkung auf die Beutelpackung ausübt. Dabei können ferner dadurch, dass der Verstärkungsstreifen nach der Erfindung von einem gesonderten Verstärkungsband gebildet ist, die Dicke und die Materialbeschaffenheit des Verstärkungsstreifensje nach den an die Tragfestigkeit der Packung gestellten Anforderungen beliebig gewählt werden. Günstig für die Tragfestigkeit der erfindungsgemässen Beutelpackung wirkt sich ferner der Umstand aus, dass der Verstärkungsstreifen ausserhalb der Querschweissnähte der Beutelpackung keine Verbindung mit der Beutelwand hat, sondern lose an dieser entlang verläuft. Die Krafteinleitung in den Verstärkungsstreifen beim Tragen der Packung erfolgt somit lediglich über die den Füllraum begrenzenden Querschweissnähte, wodurch das Wandmaterial der Verpackung beim Tragevorgang der gefüllten Verpackung weitgehend entlastet wird. Dies ermöglicht es, das Wandmaterial der Beutelpackung insgesamt in seiner Dicke entsprechend zu reduzieren, ohne dass damit eine nennenswerte Herabsetzung der Packungsfestigkeit im Grifflochbereich einhergeht. Der durch den Verstärkungsstreifen bedingte Material-Mehrverbrauch kann auf diese Weise zumindest ausgeglichen werden. Durch die Erfindung wird somit eine besonders vorteilhafte, einerseits materialsparende und andererseits hochfeste Schlauchbeutelpackung geschaffen, die, wie Versuche gezeigt haben, eine gegenüber herkömmlichen Schlauchbeutelpakkungen um das 10- bis 15fache höhere Festigkeit im Grifflochbereich aufweist. Dabei versteht sich, 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.A tubular bag pack designed in this way provides a high degree of load-bearing strength of the bag pack in the grip hole area with low material consumption for the reinforcement strip, which according to the invention is assigned to the longitudinally seam-free bag wall, in conjunction with the tube-forming longitudinal seam contained in the other bag wall, which in turn has a stiffening effect on the bag wall Bag pack exercises. Furthermore, the fact that the reinforcement strip according to the invention is formed by a separate reinforcement band allows the thickness and the material properties of the reinforcement strip to be chosen as desired, depending on the requirements placed on the load-bearing capacity of the pack. The fact that the reinforcement strip outside the transverse weld seams of the bag pack has no connection to the bag wall, but runs loosely along it, has a favorable effect on the load-bearing strength of the bag pack according to the invention. The force is introduced into the reinforcement strips when the pack is carried, therefore, only via the transverse weld seams delimiting the filling space, whereby the wall material of the packaging is largely relieved when the filled packaging is carried. This makes it possible to reduce the overall thickness of the wall material of the bag pack accordingly decorate without any significant reduction in packing strength in the finger hole area. The additional material consumption caused by the reinforcement strip can at least be compensated in this way. The invention thus creates a particularly advantageous, on the one hand material-saving and on the other hand high-strength tubular bag pack which, as tests have shown, has a ten to 15 times higher strength in the grip hole area than conventional tubular bag packs. It goes without saying that a wide variety of suitable materials can be used for the reinforcement strip, such as, for example, the same, thicker or thinner material as that of the bag walls, for example polyethylene, or different, stronger and therefore thinner material such as that of the bag walls, for example ribbon fabric.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der nachstehenden Beschreibung in Verbindung mit der Zeichnung, deren einzige Figur ein Ausführungsbeispiel des Gegenstands der Erfindung in einer schematischen Vorderansicht veranschaulicht.Further features and advantages of the invention emerge from the subclaims and the following description in conjunction with the drawing, the sole figure of which illustrates an exemplary embodiment of the object of the invention in a schematic front view.
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 Schlauchbeutelpakkung 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
Die Schlauch beutel packung 1 umfasstferner 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
Derfüllgutfreie obere Randbereich 8 istalsTragmöglichkeit 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. Dabei ist die in Querrichtung der Packung 1 gemessene Breite des Verstärkungsstreifens 12 etwa gleich der halben Packungsbreite gewählt.The filling-free

Die Krafteinleitung in den Verstärkungsstreifen 12 beim Tragen der Packung 1 erfolgt somit lediglich über die Kopfschweissnaht 7 und 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
Der Verstärkungsstreifen 12 ist vorteilhaft im Inneren des Beutels angeordnet, weil dadurch ein versehentliches Beschädigen oder Abreissen des Verstärkungsstreifens 12 durch äussere Einflüsse verhindert ist.The reinforcing
