Description
Die Erfindung bezieht sich auf einen Beutel aus thermoplastischer Kunststoffolie mit durch Seitenschweißnähte verbundener Vorderwand und Rückwand, einer sich über die gesamte Breite des Beutels erstreckenden Einfüllöffnung und einem in deren Bereich angeordneten, durch die Seitenschweißnähte mit dem Beutel verbundenen Zugband sowie einem letzteres in seinem mittleren Bereich teilweise freilegenden Griffloch in der Vorderwand und Rückwand.The invention relates to a bag made of thermoplastic plastic film front wall and rear wall connected by side welds, one over the entire width of the bag extending filling opening and one in the area arranged drawstring connected to the bag by the side welds as well as a handle hole partially exposed in the middle of the latter Front wall and back wall.
Beutel der vorgenannten Art sind in vielfältiger Ausführung bekannt. So geht beispielsweise aus DE-C-38 21 905 ein Verfahren zum Herstellen von Beuteln mit Zugbändern aus thermoplastischer Kunststoffolie hervor, bei dem jeweils ein Zugband in einen an der Einfüllöffnung vorgesehenen umgeschlagenen und angeschweißten Saum eingelegt wird, der mit der Seitenschweißnaht verschweißt ist. Ein Griffloch im mittleren Bereich des Saumes ermöglicht das Ergreifen des Zugbandes und Tragen des Beutels. Bei diesen herkömmlichen Beutein entsteht durch das Festschweißen des freien Endes der Saumumschläge an der einlagigen Vorderwand und Rückwand des Beutels eine Dünnstelle, die mit der vollen Belastung des Füllgutes des Beutels belastet wird. Erst an zweiter Stelle trägt das durch die Seitenschweißnähte am Beutel festgelegte Zugband. Je nach Art des Füllgutes bzw. dessen Gewichtes werden diese herkömmlichen Beutel im Bereich der Dünnstelle durch Einreißen leicht zerstört, so daß diese Art Beutel nur dann zum Einsatz gelangen kann, wenn entweder leichtes Füllgut eingefüllt wird oder aber im Falle von schwerem Füllgut das Folienmaterial und die Foliendicke entsprechend bemessen werden.Bags of the aforementioned type are known in a variety of designs. For example from DE-C-38 21 905 a method for manufacturing bags with drawstrings made of thermoplastic plastic film, in which each a drawstring in a folded and provided at the filling opening welded seam is inserted, which is welded to the side weld. A grip hole in the middle of the hem allows you to grasp the drawstring and carrying the bag. In these conventional prey, welding occurs the free end of the hem envelopes on the single-layer front wall and Back wall of the bag is a thin area, with the full load of the product Bag is charged. Only in second place does this come through the side welds Bag set drawstring. Depending on the type of product or its weight these conventional bags in the area of the thin area are easily destroyed by tearing, so that this type of bag can only be used when either light Filling material is filled or, in the case of heavy filling material, the film material and the film thickness can be measured accordingly.
Aus US-A-3,772,968 ist bei einer besonderen Ausführungsvariante
gemäß Fig. 4 ein Beutel aus thermoplastischer Kunststoffolie bekannt geworden, dessen
Vorderwand und Rückwand jeweils eine Außenfolie und einen vollflächig dazu
verlaufende Innenfolie aufweisen. Die beiden Folien sind im Bodenbereich des Beutels
miteinander verschweißt. In einem dem Bodenbereich gegenüberliegenden Kopfbereich
befindet sich eine Einfüllöffnung. Zum Verschließen dieser Einfüllöffnung ist zwischen
der Außenfolie und der Innenfolie der Vorderwand und Rückwand jeweils ein Zugband
eingesetzt, daß aus einem oberen Bandteil und einem damit über eine Perforation
verbundenen unteren Bandteil besteht. Die Bandenden des oberen Bandteils und des
unteren Bandteils sind an gegenüberliegenden Seiten des Beutels mit der Vorderwand
und Rückwand verbunden und zwar über dort angebrachte Perforationslappen.
Unmittelbar daneben zur Innenseite des Beutels hin, sind Grifflöcher angebracht, über die
nach dem Abreißen der Perforationslappen und damit Freilegen der Bandteile diese nach
außen gezogen werden können, so daß die jeweils gegenüberliegenden Längsseite des
Beutels des Kopfbereichs nach innen gezogen wird. Dadurch ist zwar mehr oder weniger
ein Verschließen des Beutels möglich, jedoch ist der Aufwand zur Herstellung einer
derartigen Verschlußanordnung recht aufwendig.From US-A-3,772,968 is a
Der Erfindung liegt die Aufgabe zugrunde, aus thermoplastischer Kunststoffolie bestehende und mit einem Zugband versehene Beute! der eingangs genannten Art zu schaffen, die sich trotz vergleichsweise dünner Folienstärke durch eine hohe Festigkeit auszeichnen und die sich bei einer weitgehend durchgehenden Fertigung mit hoher Produktionsgeschwindigkeit herstellen lassen.The invention has for its object from thermoplastic plastic film existing loot with a drawstring! of the type mentioned at the beginning create, which despite high film strength is comparatively thin distinguish themselves and which are in a largely continuous production with high Have production speed established.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorderwand und die Rückwand jeweils neben einer äußeren Folienlage eine sich über die gesamte Wandfläche erstreckende innere Folienlage aufweist, die jeweils außerhalb des bis auf den Bereich des Grifflochs zwischen der äußeren und inneren Folienlage angeordneten Zugbandes im außen liegenden Randbereich der Einfüllöffnung durch eine Längsschweißnaht mit der äußeren Folienlage verbunden ist.This object is achieved in that the front wall and the Rear wall next to an outer layer of film each over the entire wall surface extending inner film layer, each of which outside of the Area of the grip hole arranged between the outer and inner film layer Drawstring in the outer edge area of the filling opening by a longitudinal weld is connected to the outer film layer.
Ein derart beschaffener Beutel hält einer höheren Belastung durch Füllgut besser stand, da der Belastungszug nicht nur von den Seitenschweißnähten im Bereich des eingeschweißten Zugbandes aufgenommen wird, sondern zugleich auch durch die Längsschweißnaht zwischen den Folienlagen der Vorderwand und Rückwand. Bei einer derartigen Beutelausbildung können nicht nur die innere und äußere Folienlage dünner als die Kunststoffolie bei herkömmlichen Beuteln ausgebildet sein, sondern sie können auch je nach Bedarf aus unterschiedlichen Kunststoffmaterialien, beziehungsweise aus Materialien mit einer unterschiedlichen Dicke ausgebildet sein. Zu einer guten Kraftaufnahme trägt auch bei, wenn das Griffloch in Bezug auf die Höhe, beziehungsweise Breite des Zugbandes im wesentlichen mittig angeordnet ist. Dadurch wird einmal unterhalb des Zugbandes ein freier Raum zum Durchgreifen erzielt und zum anderen bilden sich im Bereich der Längsschweißnaht am freiliegenden Ende des Grifflochs Materialspitzen, die ebenfalls ein Einreißen der durch die Längsschweißnaht miteinander verbundenen Vorder- und Rückwand verhindern.Such a bag is better able to withstand a higher load from the filling material, since the load train not only from the side welds in the area of the welded drawstring is included, but also by the Longitudinal weld between the film layers of the front wall and rear wall. At a Such bag formation can not only thinner than the inner and outer film layer the plastic film can be formed with conventional bags, but they can also depending on requirements from different plastic materials, or from Materials with a different thickness can be formed. For a good one Force absorption also helps if the grip hole in terms of height, or width of the drawstring is arranged substantially centrally. Thereby once a free space to reach through is achieved below the drawstring and others form in the area of the longitudinal weld at the exposed end of the Handle holes material tips, which also tear through the longitudinal weld Prevent interconnected front and rear walls.
Dies gilt insbesondere für den Fall, daß der Radius des Grifflochs etwa der Breite beziehungsweise Höhe des Zugbandes entspricht.This applies in particular to the case where the radius of the grip hole is approximately the width or the height of the drawstring.
In alternativer Ausführung ist vorgesehen, daß das Griffloch mit Abstand zur Einfüllöffnung angeordnet ist und die Abstandsstrecke zwischen der Einfüllöffnung und der dieser zugewandten Randkante des Griffloches mit einer Perforation versehen ist. Die Anordnung des Grifflochs mit Abstand zur Randkante der Einfüllöffnung ergibt nicht nur einen stabileren Beutel, sondern erleichtert auch dessen Herstellung, da die im Bereich der Einfüllöffnung liegende Längsschweißnaht besser erstellt werden kann.In an alternative embodiment it is provided that the grip hole is at a distance from Filling opening is arranged and the distance between the filling opening and which is provided with this perforated edge of the grip hole with a perforation. The Arranging the grip hole at a distance from the edge of the fill opening not only results a more stable bag, but also facilitates its manufacture, since the in the area longitudinal weld seam lying in the fill opening can be created better.
In einer noch weiter abgewandelten Ausführungsform ist das Griffloch selbst von einem Perforierschnitt begrenzt und der dadurch gebildete Lochlappen unmittelbar oder als Träger einer Wertmarke oder einer sonstigen Kennzeichnung ausgebildet. Das Aufbringen von Wertmarken oder sonstiger Kennzeichnungen gewinnt im Zuge notwendiger Abfallbeseitigung bzw. Recyclingmaßnahmen zunehmend an Bedeutung, insbesondere um aufzuzeigen, daß bestimmte Gebühren entrichtet worden sind.In a further modified embodiment, the grip hole itself is one Perforated cut limited and the perforated flap thus formed directly or as Carrier of a token or other identification. The application of tokens or other labels wins in the course of necessary Waste disposal or recycling measures are becoming increasingly important, in particular to show that certain fees have been paid.
Ein erfindungsgemäß ausgebildeter Beutel aus thermoplastischer Kunststoffolie läßt sich auch besonders einfach und günstig herstellen, beispielsweise in der Weise, daß ausgehend von zwei vorzugsweise von Abwickelrollen abgezogenen flachen Kunststoffbahnen diese deckend zusammengelegt und nach Art eines U umgefaltet werden sowie in den so entstandenen offenen Kopfbereich das Griffloch eingestanzt und jeweils zwischen der inneren und äußeren Bahnlage ein vorzugsweise aus Kunststoff bestehendes Zugband eingeführt wird und darauf die Bahnlagen im Kopfbereich paarweise zugeschweißt werden, wonach schließlich die Seitenschweißnähte und gegebenenfalls eine Perforation zur Bildung der einzelnen Beute in die Kunststofffolienbahn eingebracht werden.A bag made of thermoplastic plastic film designed according to the invention can be also produce particularly easily and cheaply, for example in such a way that starting from two flat plastic webs, preferably drawn off from unwinding rollers these are folded together and folded over like a U. such as the grip hole is punched into the resulting open head area and each between the inner and outer web layer, preferably made of plastic existing tension band is inserted and then the web layers in the head area are welded in pairs, after which the side welds and if necessary, a perforation to form the individual prey in the plastic film web be introduced.

In Fig. 1 ist ein Beutel aus thermoplastischer Kunststoffolie dargestellt, dessen
Vorderwand 1 und Rückwand 2 jeweils aus einer äußeren 1' und einer inneren 2'
Folienlage bestehen, wobei die Folienlagen 1' und 2' je nach Verwendungszweck des
Beutels aus unterschiedlichen Kunststoffmaterialien hergestellt sein können und/oder
gegebenfalls unterschiedliche Dicken aufweisen können. Im Bereich einer oberen
Einfüllöffnung 6 ist zwischen den durch eine Längsschweißnaht 4 miteinander
verbundenen Folienlagen jeweils ein aus Kunststoff bestehendes Zugband 3 eingelegt,
das beim Herstellen der Beutel durch Seitenschweißnähte 5 ebenfalls fest mit
dem Beutel verschweißt ist. Im mittleren Bereich des Zugbandes 3 ist im Beutel ein
Griffloch 8 vorgesehen, über das zum Verschließen des Beutels das Zugband 3
herausgezogen und verknotet werden kann. In Fig. 1, a bag made of thermoplastic film is shown, the
Wie aus Fig. 1 ersichtlich, ist das Griffloch von einer im wesentlichen kreisförmigen
Ausnehmung gebildet, deren Mittelpunkt in etwa auf der halben Breite bzw. Höhe des
Zugbandes 3 liegt und dessen Öffnung im Bereich der Längsschweißnaht 4 weniger
als 180° beträgt. Als optimal hat sich herausgestellt, wenn der Radius des Griffloches
8 etwa der Breite bzw. Höhe des Zugbandes 3 entspricht.As can be seen from Fig. 1, the grip hole is of a substantially circular shape
Recess formed, the center of about half the width or height of the
Das Zugband kann vorzugsweise aus dem gleichen Material wie entweder die innere

In den Fig. 4 bis 6 sind Abwandlungen bezüglich der Anordnung des Grifflochs 8
dargestellt. Allen Ausführungen gemeinsam ist, daß das kreisförmige Griffloch 8 mit
Abstand zur Randkante der Einfüllöffnung 6 angeordnet ist und die Abstandsstrecke
perforiert ist. Während in den Fig. 4 und 6 die Perforation 9 als Perforierschnitt 11
ausgebildet ist, besteht demgegenüber die Perforation in Fig. 5 aus einer Lochperforation

die Perforation 9 eingerissen und die Zugbänder gegebenenfalls miteinander verknotet.When the bag is used, the
Bei der Ausführung nach Fig. 6 ist das Griffloch 8 selbst durch eine Perforation 13
begrenzt, so daß ein dadurch begrenzter Lochlappen 14 entsteht. Dieser muß bei
Gebrauch des Beutels zunächst aufgestoßen werden, z. B. mit dem Daumen, um das
Zugband 3 ergreifen zu können. Der Lochlappen 14 kann entweder unmittelbar selbst
als heraustrennbare Wertmarke bzw. als Kennzeichnungselement oder als Träger für
eine aufklebbare Wertmarke bzw. ein Kennzeichnungselement ausgebildet sein. Bei
Gebrauch des Beutels wird die abgetrennte Wertmarke an beliebiger Stelle auf den
Beutel geklebt, um aufzuzeigen, daß z. B. bestimmte Gebühren entrichtet worden
sind bzw. der Beutel ordnungsgemäß gekauft worden ist. Die Anordnung der Wertmarke
im Bereich des Grifflochs hat auch den Vorteil, daß beim üblichen Aufrollen
der Beutel zu einer Beutelrolle die Wertmarken gegen Entwendung sicher angebracht
sind. In the embodiment according to FIG. 6, the
Ein besonders günstiges Verfahren zum Herstellen eines Beutels aus thermoplastischem
Kunststoff mit Zugband und Griffloch ergibt sich dann, wenn ausgehend von
zwei vorzugsweise von Abwickelrollen abgezogenen flachen Kunststoffbahnen diese
deckend zusammengelegt und nach Art eines U umgefaltet sowie in den so entstandenen
offenen Kopfbereich das Griffloch 8 eingestanzt und jeweils zwischen der
inneren und äußeren Bahnlage ein vorzugsweise aus Kunststoff bestehendes Zugband
3 eingelegt wird und darauf die Bahnlagen im Kopfbereich
außerhalb des Zugbandes
paarweise zugeschweißt
werden, worauf schließlich die Seitenschweißnähte 5 und gegebenenfalls eine
Perforation zur Bildung der einzelnen Beutel eingebracht werden.A particularly inexpensive process for producing a thermoplastic bag
Plastic with drawstring and grip hole results when starting from
two flat plastic webs, preferably pulled off from unwinding rollers
opaque folded and folded like a U and in the resulting
open head area punched the
Die Herstellung des Beutels braucht aber nicht unbedingt aus zwei flach aufeinandergelegten Kunststoffbahnen erfolgen. Es eignet sich auch ein durch Umlegen einer Flachbahn erzeugter Folienhalbschlauch oder ein zunächst geschlossener Folienschlauch, der einseitig aufgeschnitten wird.However, the bag does not necessarily need to be made from two flat layers Plastic sheets are made. It is also suitable by flipping a flat web of semi-tubular film or an initially closed film tube, which is cut open on one side.
Die Herstellung von Beuteln mit Wertmarken oder Kennzeichnungen wird kaum nachteilig beeinträchtigt, da zum Aufbringen der Wertmarken die eine Randkante der Folienlage ein Stück nach außen umgeklappt und darauf die Wertmarke aufgebracht wird, wonach das umgeklappte Ende wieder nach innen zurückgeklappt wird. Danach wird die Perforation für das Griffloch eingebracht. Die weitere Herstellung des Beutels erfolgt ohne Abänderung.The production of pouches with tokens or labels hardly becomes a disadvantage impaired because the one edge of the to apply the tokens Layer of film folded down a bit and the token applied to it after which the folded end is folded back inwards. After that the perforation for the grip hole is made. The further production of the bag takes place without modification.
Es versteht sich, daß die Erfindung nicht nur auf das dargestellte Ausführungsbeispiel beschränkt ist, sondern im Rahmen der Ansprüche auch Abänderungen zuläßt. So sind unter dem Begriff Beute auch Säcke, Taschen und dergleichen zu verstehen. Überdies können die Zugbänder aus zunächst breiteren Materialstreifen hergestellt werden, die dann schließlich zu der gewünschten Breite umgefaltet werden und in den Kopfbereich des Beutels eingelegt werden.It is understood that the invention is not limited to the illustrated embodiment is limited, but also permits changes within the scope of the claims. So the term loot also means sacks, bags and the like. In addition, the drawstrings can be made from initially wider strips of material which are then finally folded to the desired width and in the head area of the bag.
