Wiaderverschließbare SchlauchbeutelpackungResealable tubular bag packaging
Die Erfindung bezieht sich auf eine wiederverschließbare Schlauchbeutelpackung.The invention relates to a resealable tubular bag package.
Schlauchbeutel haben einen großen Anteil am Vespo Sie werden an Schlauchbeutelmasehinon hergestellt. An diesen wird sine Packstoffbahn von einer Rolle abgewickelt r über eine Formschulter gefühlt und dabei schiauchartig umgeformt. Die in Berührung kommenden Folienrandbereiche werden dann miteinander verschweißt. Dies geschieht durch eine parallel zur Folienbewegungsrichtung positionierte, sog. Längsäiegslbacke. Die entstehende Längsnaht des Folienschlauchs kann auf zwei verschiedene Arten ausgeführt werden. Zum einen konn man die Randbereiche der schlauchartig umgeformten Folie aufeinander legen und miteinander verschweißen. Dies setzt voraus, daß das Folienmaterial beidseitig heißsiegelfähig ist. Zum anderen kann man die Folienrandbereiche auf den im Inneren des Folienschlauches befindlichen PackstoÜfoberflachen verschweißen und die dadurch entstandene Flosse parallel zur äußeren Oberfläche des Folienschlauchs legen (Umlegenaht).Tubular bags account for a large proportion of Vespo. They are manufactured using tubular bags. A web of packaging material is unwound from a roll , passed over a forming shoulder and formed into a tube. The film edge areas that come into contact are then welded together. This is done by a so-called longitudinal welding jaw positioned parallel to the direction of film movement. The resulting longitudinal seam of the film tube can be made in two different ways. On the one hand, the edge areas of the tube-shaped film can be placed on top of one another and welded together. This requires that the film material is heat-sealable on both sides. On the other hand, the film edge areas can be welded to the packaging material surfaces inside the film tube and the resulting fin can be placed parallel to the outer surface of the film tube (folding seam).
Wiederverschlußmöglichkeiten durch Aufbringung entsprechender Elemente auf die Packstoffoberfläche sind bekannt (siehe GM 88 12 976).Reclosure options by applying appropriate elements to the packaging material surface are known (see GM 88 12 976).
Ein Nachteil bei den bisher verwendeten Wiederverschlußtechniken ist uitmals die getaktete Aufbringung der dazu benötigten Elemente. Dadurch ist ihr Einsatz an kontinuierlich arbeitenden Verpackungsmaschinen kaum möglich. Ein weiterer Nachteil ergibt sich daraus, d^fl ein Wiederverschluß des Schlauchbeutels durch Einrollen oder Einfalten des Beutels nur xn diskreten, durch den Wiederverschlußmechanismus bestimmten Schritten, nicht aber beliebig erfolgen kann. Und schließlich führen Wiederversehlußelemente, die auf Hüllstoffoberflächen gebracht werden, zu einer Verringerung der werbewirksamen Packstoffoberfläche.A disadvantage of the reclosure techniques used to date is the synchronized application of the elements required. This makes their use on continuously operating packaging machines almost impossible. A further disadvantage is that the tubular bag can only be reclosed by rolling or folding the bag in xn discrete steps determined by the reclosure mechanism, and not at will. And finally, reclosure elements that are applied to the surface of the wrapping material lead to a reduction in the advertising-effective packaging material surface.
Der Erfindung liegt die Aufgabe zugrunde, die erwähnten Nachteile bei Wiederverschlußtechniken an Schlauchbeuteln zu beseitigen. Der geöffnete Schlauchbeutel soll nach beliebigem Einrollen oder Einknicken in der erreichten Position fixierbar sein. Die Elemente der Wiederverschlußtechnik sollen innerhalb oder unterhalb der umgelegten Längsnaht des Schlauchbeutels untergebracht werden und schließlich soll die Aufbringung dieser Elemente auch im kontinuierlichen Arbeitsverfahren möglich sein.The invention is based on the task of eliminating the above-mentioned disadvantages of reclosure techniques on tubular bags. The opened tubular bag should be able to be fixed in the position reached after being rolled or folded in any way. The elements of the reclosure technique should be accommodated inside or below the folded longitudinal seam of the tubular bag and finally, the application of these elements should also be possible in a continuous working process.
Erreicht ist dieses Ziel dadurch, daß innerhalb oder unterhalb der umgelegten Längsnaht des Schlauchbeutels ein Element angebracht ist, welches dem eingerollten oder eingefalteten Beutelmaterial eine Fixierung nach Ausführung mehrerer Rolloder Knickvorgänge in Oer dadurch erreichten Position ermöglicht. Bevorzugte Ausführungsbeispiele sind in den Ansprüchen 2 bis gekennzeichnet.This aim is achieved by an element being mounted inside or below the folded longitudinal seam of the tubular bag, which element enables the rolled or folded bag material to be fixed in the position achieved after several rolling or folding operations have been carried out. Preferred embodiments are characterized in claims 2 to .
In den Zeichnungen ist der Erfindungsgegenstand an zwei Ausführungsbeispielen dargestellt.The subject matter of the invention is shown in two embodiments in the drawings.
Der wiede verschließbare Schlauchbeutel 1 kann unterhalb seiner umgelegten Längsnaht 2 mit einer klabrigen Substanz 4 (Abb. 1) oder innerhalb der Längsnaht 2 mit einer diese versteifende Einlage 5 (Abb. 2) versehen werden. Nach dem Durchtrenrien des Beutels ur «rhalb der Kopfnaht 3 und parallel zu dieser durch Schneiden bzw. Aufreißen entlang einer Perforationslinie 6 oder mittels eines Aufreißbändchens wird ein, dJ j Kopfnaht ~ enthaltender, Beutelabschnitt abgetrennt. Der somit geöffnete Schlauchbeutel i kann erfindungsgemäß auf zwei verschiedene Arten wiederverschlossen werden. Zum einen (Abb. 1) wird die umgelegte Längsnaht 2 von einer sich darunter befindlichen klebrigen Substanz 4 abgezogen und aufgeklappt. Die dadurch freigelegte Klebeschicht 4 wird nach dem Einrollen und/nrler Einknicken der sich unterhalb der Aufreißlinie befindlichen und parallel zu dieser verlaufenden PackungszoneThe resealable tubular bag 1 can be provided with a sticky substance 4 (Fig. 1) below its folded longitudinal seam 2 or with an insert 5 (Fig. 2) inside the longitudinal seam 2 that stiffens it. After the bag has been severed outside the top seam 3 and parallel to it by cutting or tearing along a perforation line 6 or by means of a tear-open tape, a bag section containing the top seam ~ is severed. The tubular bag 1 thus opened can be resealed in two different ways according to the invention. Firstly (Fig. 1), the folded longitudinal seam 2 is pulled away from a sticky substance 4 located underneath and opened up. The adhesive layer 4 thus exposed is removed after rolling up and/or folding the packing zone located below the tear line and running parallel to it.

zu deren Fixierung in nahezu beliebiger Position verwendet. Die Klebeschicht 4 kann z.B. in Form einer Haftguramierung am Folienmaterial angebracht werden oder durch einen beidseitig klebbaren Streifen die geforderte Funktion erfüllen.used to fix them in almost any position. The adhesive layer 4 can be attached to the film material in the form of an adhesive rubber coating, for example, or can fulfill the required function using a strip that can be stuck on both sides.
Zum anderen (Abb. 2) kann eine verformbare Einlage 5 zwischen oder unterhalb der beiden aufeinander geschweißten Folienrandbereiche, welche die Länqsnaht ausbilden, eingehr,ic)>t WRi len. Dieses elastische Element 5 (z.B. Draht oder diener Metallstreifen) bewirkt die Fixierung des zum Zwecke des Wiederverschlußes umgeknickten oder eingerollten Packungsmaterials.On the other hand (Fig. 2), a deformable insert 5 can be inserted between or below the two welded film edge areas, which form the longitudinal seam. This elastic element 5 (e.g. wire or metal strip) fixes the packaging material that has been folded over or rolled up for the purpose of reclosure.
Dir Vorteile rl^r erfindungsgemäßen Wiederve^ "chlußtechnik sind neben der einfachen Handhabung die Möglichkeit, eine Packung Ln nahezu beliebiger Art und Wei^e in Längsrichtung des Srhlauchbeutels zu verschließen. Die dazu benötigten Elemente sind bei der ungeöffneten Packung versteckt angeordnet. Eine Herste]'ung les entsprechenden Schlauchbeutels kann sowohl getaktet als auch kotninuierlich eriolgen.The advantages of the reclosure technology according to the invention are, in addition to the ease of handling, the possibility of closing a package in almost any way in the lengthwise direction of the tubular bag. The elements required for this are hidden in the unopened package. The corresponding tubular bag can be manufactured either in a synchronized manner or continuously.
Schließlich kann man auf die Anbringung der Wiederverschließelemente während der Schlauchbeutelherstellung verzichten, indem man eine entsprechend vorbereitete Folienrolle einsetzt.Finally, it is possible to dispense with the attachment of the reclosing elements during the tubular bag production by using an appropriately prepared film roll.
