Definitions
- the invention relates to a pack, in particular a tubular bag pack, with a casing consisting of a flat, flexible and foldable packaging material, in which the packaging material has a doubling area in which it forms two layers which are connected to one another with the aid of a binding agent, one of the layers in FIG passes over an envelope part, which is connected to a tear-open element, which continues with its beginning into the doubling area.
- a pack of this type is known from DE-A-1 536188 and is used there in particular for packaging perishable luxury items such as. B. soft cheese.
- the lumpy packaging material is first wrapped in a sheet of packaging material, which has a sealable and adhesive coating made of an ethylene-vinyl acetate-paraffin wax mixture on the inside, and then the envelope is closed by forming a longitudinal sealing seam and then closed by two transverse sealing seams .
- Across the packaging material sheet to be used and adhering to the sealable coating there is a tear tape which serves as a tear-open element, which then runs in the packaging envelope next to and along the transverse sealing seam or whose beginning is at one of the two packaging material doubling areas forming transverse sealing seams.

- This packaging material layer also has pre-slots on both sides of the grip tab that extend into the sealing seam area.
- a gas-tightness of the sealing medium must also be provided. However, this is not the case in the package described in the aforementioned DE-A because of the paraffin wax-based sealing medium used there. If, however, a sealing medium is used in which the two packaging material layers are connected to one another and a tear strip in the area of the sealing seam in which the opening of the tear organ is located, this sealing seam forms a connection for all parts connected to one another at the same time high mechanical strength. As a result, tearing open the packaging envelope is made considerably more difficult, if not prevented, particularly in the initial region of the tear-open element or tear strip.
- the invention seeks to remedy this.

Abstract
Description
Die Erfindung betrifft eine Packung, insbesondere eine Schlauchbeutelpackung, mit einer aus einem flächigen, flexiblen und faltbaren Verpakkungsmaterial bestehenden Hülle, bei der das Verpackungsmaterial einen Dopplungsbereich aufweist, in welchem es zwei mit Hilfe eines Bindemittels flächig miteinander verbundene Lagen bildet, wobei eine der Lagen in einen Hüllenteil übergeht, der mit einem Aufreißorgan verbunden ist, welches sich mit seinem Anfang bis in den Dopplungsbereich hinein fortsetzt.The invention relates to a pack, in particular a tubular bag pack, with a casing consisting of a flat, flexible and foldable packaging material, in which the packaging material has a doubling area in which it forms two layers which are connected to one another with the aid of a binding agent, one of the layers in FIG passes over an envelope part, which is connected to a tear-open element, which continues with its beginning into the doubling area.
Eine Packung dieser Art ist aus der DE-A-1 536188 bekannt und dient dort insbesondere zum Verpacken von verderblichen Genußmitteln wie z. B. Weichkäse. Zur Herstellung der Pakkungshülle wird hier das stückige Verpackungsgut in einem Verpackungsmaterial-Blatt, welches an seiner Innenseite eine siegel- und klebefähige Beschichtung aus einem Äthylenvenylacetat-Paraffinwachs-Gemisch aufweist, zunächst eingeschlagen und die Hülle dann durch Bildung einer Längssiegelungsnaht und anschließend von zwei Quersiegelungsnähten geschlossen. Quer über das einzusetzende Verpackungsmaterial-Blatt und an der siegelfähigen Beschichtung haftend verläuft ein als Aufreißorgan dienendes Reißband, das dann in der Packungshülle neben und längs der Quersiegelungsnaht verläuft bzw. deren Anfang sich an einer der beiden Verpackungsmaterial-Dopplungsbereiche bildende Quersiegelungsnähte befindet. An dieser Quersiegelungsnaht weist die Verpackungsmaterial-Lage, welche in dem mit den Reißstreifen verbundenen Hüllenteil übergeht, an der Siegelungsnaht-Kante einen vorspringenden Grifflappen auf, unter dem sich der Reißstreifen-Anfang befindet. Diese Verpakkungsmaterial-Lage weist überdies an beiden Seiten des Grifflappens in den Siegelnahtbereich hineinreichende Vorschlitzungen auf. Durch Abziehen des Reißstreifens wird - erleichtert durch diese Vorschlitzungen - in der Packungshülle eine schlitzförmige Öffnung erzeugt, die dann durch Verformung der Hülle so weit vergrößert wird, daß das Verpackungsgut der Hülle entnommen werden kann.A pack of this type is known from DE-A-1 536188 and is used there in particular for packaging perishable luxury items such as. B. soft cheese. To produce the packaging envelope, the lumpy packaging material is first wrapped in a sheet of packaging material, which has a sealable and adhesive coating made of an ethylene-vinyl acetate-paraffin wax mixture on the inside, and then the envelope is closed by forming a longitudinal sealing seam and then closed by two transverse sealing seams . Across the packaging material sheet to be used and adhering to the sealable coating, there is a tear tape which serves as a tear-open element, which then runs in the packaging envelope next to and along the transverse sealing seam or whose beginning is at one of the two packaging material doubling areas forming transverse sealing seams. At this transverse sealing seam, the layer of packaging material, which merges into the envelope part connected to the tear strips, has a projecting grip tab on the edge of the sealing seam, below which the start of the tear strip is located. This packaging material layer also has pre-slots on both sides of the grip tab that extend into the sealing seam area. By pulling off the tear strip, a slit-shaped opening is created in the packaging envelope - facilitated by these pre-slots - which opening is then enlarged by deformation of the envelope to such an extent that the packaging material can be removed from the envelope.
Sollen nun Packungen der eingangs genannten Art zumindest weitgehend vollständig gasdicht sein, muß, neben einer Gasdichtheit des Verpackungsmaterials selbst, auch eine Gasdichtheit des Siegelungsmediums gegeben sein. Dies ist bei der in der genannten DE-A beschriebenen Packung wegen des dort verwendeten Siegelmediums auf Paraffinwachs-Basis aber nicht der Fall. Wird nun aber ein Siegelmedium verwendet, bei dem im Bereich der Siegelungsnaht, in dem sich der Aufreißorgan-Anfang befindet, die beiden Verpackungsmaterial-Lagen untereinander und ein Aufreißstreifen gasdicht miteinander verbunden sind, so bildet diese Siegelungnaht für alle miteinander verbundenen Teile gleichzeitig eine Verbindung mit hoher mechanischer Festigkeit. Dadurch wird gerade im Anfangsbereich des Aufreißorgans bzw. Reißstreifens ein Aufreißen der Packungshülle wesentlich erschwert wenn nicht verhindert.If packs of the type mentioned at the beginning are to be at least largely completely gas-tight, in addition to a gas-tightness of the packaging material itself, a gas-tightness of the sealing medium must also be provided. However, this is not the case in the package described in the aforementioned DE-A because of the paraffin wax-based sealing medium used there. If, however, a sealing medium is used in which the two packaging material layers are connected to one another and a tear strip in the area of the sealing seam in which the opening of the tear organ is located, this sealing seam forms a connection for all parts connected to one another at the same time high mechanical strength. As a result, tearing open the packaging envelope is made considerably more difficult, if not prevented, particularly in the initial region of the tear-open element or tear strip.
Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, bei einer Packung mit einer aus einem flächigen, flexiblen und faltbaren Verpackungsmaterial bestehenden Hülle sowie mit einem Aufreißorgan, dessen Anfang sich an einem Dopplungsbereich des Verpakkungsmaterials befindet, die Packung weitgehend gasdicht ausbilden zu können und gleichzeitig durch einfache Maßnahmen die Betätigung des Aufreißorganes zu erleichtern.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of making the package largely gas-tight in the case of a package with a cover consisting of a flat, flexible and foldable packaging material and with a tear-open element, the beginning of which is at a doubling area of the packaging material to be able and at the same time to facilitate the operation of the tear-open element by simple measures.
Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert. Es zeigt
- Fig. 1 in perspektivischer, schematischer Darstellung eine Schlauchbeutelpackung gemäß der Erfindung,
- Fig. 2 eine Teildarstellung einer Schlauchbeutelpackung gemäß der Erfindung in schematischer Darstellung mit Details des Aufreißbandanfanges.
- 1 is a perspective, schematic representation of a tubular bag pack according to the invention,
- Fig. 2 is a partial representation of a tubular bag pack according to the invention in a schematic representation with details of the tear tape beginning.
Die Herstellung der Schlauchbeutelpackung erfolgt in an sich bekannter Weise dadurch, daß in der Verpackungsmaschine die kontinuierlich zulaufende Verpackungsmaterialbahn, die an vorgegebenen Stellen Schwächungslinien bzw. ein zwischen zwei in Bahn-Längserstreckung verlaufendes, an der Siegelungsschicht angebrachtes Aufreißband aufweist, in dieser Längserstreckung 1 (Fig. 1) um das Verpackungsgut, z. B. Schokoladeriegel, gefaltet und durch Bildung einer (in der Figur nicht dargestellten) Längssiegelungsnaht eine das Verpackungsgut umschließende Schlauchhülle 2 gebildet, die durch Quersiegelungsnähte 3, 3' und Durchtrennung des Verpackungsmaterials an diesen Nähten in Einzelpackungen unterteilt wird. Durch diese Quersiegelungsnähte 3, 3' werden an den Packungsenden flossenförmige Dopplungsbereiche hergestellt, an denen jeweils zwei Verpackungsmaterial-Lagen 4 und 5 bzw. 4' und 5' flächig miteinander verbunden sind. Die (in Fig. 1) an der Packungsoberseite zu liegen kommenden Verpackungsmaterial-Lagen 4, 4' gehen dabei in den oberen Teil der Packungshülle über, an deren Innenseite zwischen zwei Schwächungslinien 6 des Verpackungsmaterials ein Aufreißband 7 angebracht ist. An den Schwächungslinien sind Stege zwischen den streckenweisen Durchstanzungen vorgesehen. Der Anfang 9 des Aufreißbandes 7 befindet sich an der Unterseite eines lappenförmigen Fortsatzes 10 der Verpackungsmaterial-Lage 4 am Dopplungsbereich der Quersiegelungsnaht3 bzw. verläuft in deren Siegelungsbereich zwischen den Verpackungsmaterial-Lagen 4 und 5. Dabei sind die Verpackungsmaterial-Lagen 4 und 5 und das Aufreißband 7 durch die Siegelung flächig und gasdicht miteinander verbunden.The tubular bag pack is produced in a manner known per se by the fact that in the packaging machine the continuously tapering packaging material web, which has lines of weakness at predetermined points or a tear tape between two in the longitudinal direction of the web and attached to the sealing layer, in this longitudinal dimension 1 (Fig . 1) around the packaged goods, e.g. B. chocolate bar, folded and formed by forming a (not shown in the figure) longitudinal sealing seam enclosing the packaging
Zur Erleichterung des Einreißens ist der Auf reißbandanfang nun in einer besonderen Weise ausgebildet. Dies ist aus Fig. 2 ersichtlich, wobei der hier dargestellte Aufreißbandanfang im Gegensatz zu Fig. 1 nun keinen lappenförmigen Fortsatz aufweist.To facilitate tearing, the beginning of the tear tape is now in a special way educated. This can be seen from FIG. 2, the tear tape beginning shown here, in contrast to FIG. 1, now not having a tab-shaped extension.
Der Anfang des Aufreißbandes befindet sich an dem durch eine Quersiegelungsnaht hergestellten Dopplungsbereich aus den Verpakkungsmaterial-Lagen 4 und 5. Das an der Innenseite des (in der Fig. 2 oberen) Packungshüllenteiles bzw. der Verpackungsmaterial-Lage 4 angebrachte Aufreißband 7 liegt zwischen zwei Schwächungslinien 6 des Verpackungsmaterials, an denen man die Stege 8 zwischen den Durchstanzungen erkennt und die über den größten Teil der Packung parallel zueinander, innerhalb der Verpackungsmaterial-Lage 4 jedoch keilförmig auseinander verlaufen. Dem in der (oberen) Verpackungsmaterial-Lage 4 durch diese Schwächungslinien 6 begrenzten Bereich liegt nun in der (unteren) Verpackungsmaterial-Lage 5 ein Bereich 11 gegenüber, der durch eine U-förmig verlaufende Schwächungslinie 12 bzw. den Rand 13 des Dopplungsbereiches umschlossen ist.The start of the tear tape is located at the doubling area made of the
Zum Einreißen des Aufreißbandes faßt man im Bereich 11 des durch die beiden Lagen 4 und 5 gebildeten Dopplungsbereichs den Aufreißbandanfang an und zieht ihn in Richtung des Pfeiles 14 nach oben. Dabei wird der mit dem Anfang 9 des Aufreißbandes 7 flächig und gasdicht verbundene Bereich 11 der Verpackungsmaterial-Lage 5 an der U-förmig verlaufenden Schwächungslinie 12 abgetrennt und die zu beiden Seiten des Aufreißbandes liegenden Schwächungslinien 6 vom Dopplungsbereichs-Rand 13 aus eingerissen. Die Packung wird dann wie üblich durch weiteres Abziehen des Aufreißbandes geöffnet.To tear the tear tape, grasp the start of the tear tape in
Nachstehend werden zwei Beispiele von erfindungsgemäßen Schlauchbeutelpackungen gegeben.Two examples of tubular bag packages according to the invention are given below.
Zur Herstellung einer die erfindungsgemäße Packung bildenden Verpackungsmaterialbahn wird eine einseitig gestrichene, satinierte Papierbahn eines Flächengewichts von 60-100 g/ m2 eingesetzt, die in einer Rotationsdruckmaschine gleichzeitig mit einem Oberflächendekordruck und streckenweisen Durchstanzungen längs der am Verpackungsmaterial vorgesehenen Schwächungslinien versehen wird. Eine bandförmige Aluminiumfolie einer Dicke von 0,008 bis 0,012 mm wird darauf einseitig mit einem Kaschiermedium beschichtet und gegen die bedruckte und Schwächungslinien aufweisende Papierbahn laminiert. Dieser Verbund wird schließlich an der von der Papierbahn abgewandten Seite mit einem Kaltkleber beschichtet.To produce a packaging material web forming the package according to the invention, a satin-coated paper web with a basis weight of 60-100 g / m 2 that is coated on one side is used, which is simultaneously provided in a rotary printing machine with surface decor printing and punched punchings along the weakening lines provided on the packaging material. A strip-shaped aluminum foil with a thickness of 0.008 to 0.012 mm is coated on one side with a lamination medium and laminated against the printed and weakened paper web. This composite is finally coated with a cold adhesive on the side facing away from the paper web.
Auf die so hergestellte Verpackungsmaterialbahn wird nun als Aufreißband ein dünnes einseitig mit einer Kaltkleberbeschichtung versehenes Polyäthylenband mit seiner kaltkleberfreien Seite aufgebracht. Dies erfolgt beispielsweise dadurch, daß bei der Herstellung von Schlauchbeutelpackungen das Polyäthylenband in Verpackungsmaterialband-Längsrichtung mittels eines thermoplastischen Bindemittels, wie z. B. Wachs, auf die Kaltkleberbeschichtung der der Verpackungsmaschine zugeführten Verpakkungsmaterialbahn heiß anlaminiert wird.A thin polyethylene tape provided with a cold adhesive coating on one side with its cold adhesive-free side is now applied as a tear tape to the packaging material web thus produced. This takes place, for example, in that in the production of tubular bag packs, the polyethylene tape in the longitudinal direction of the packaging material tape by means of a thermoplastic binder, such as, for. B. wax, is hot laminated onto the cold adhesive coating of the packaging material web fed to the packaging machine.
Im Gegensatz dazu wird bei der Herstellung von bekannten Schlauchbeutelpackungen das Aufreißband auf die Verpackungsmaterialbahn quer, d. h. insbesondere senkrecht zu deren Längserstreckung aufgebracht, wozu in der Verpackungsmaschine sehr aufwendige maschinentechnische Maßnahmen erforderlich sind, die bei dem erfindungsgemäßen Verfahren vermieden werden.In contrast, in the manufacture of known tubular bag packs, the tear tape is transversely on the packaging material web, i. H. in particular applied perpendicular to their longitudinal extent, for which purpose very complex mechanical engineering measures are required in the packaging machine, which are avoided in the method according to the invention.
Die weiteren Schritte zur Herstellung der Schlauchbeutelpackungen erfolgen dann wie anhand von Fig. 1 beschrieben, wobei die auszuführenden Siegelungsnähte durch Kaltsiegelungen realisiert werden.The further steps for producing the tubular bag packs then take place as described with reference to FIG. 1, the sealing seams to be carried out being realized by cold sealing.
Das gemäß diesem Beispiel einzusetzende Verpackungsmaterial unterscheidet sich von dem in Beispiel 1 beschriebenen dadurch, daß statt der Papierbahn eine Kunststoffbahn, insbesondere eine Zellglasbahn mit einem Flächengewicht von 28-40 g/m2, und statt der Kaltkleberbeschichtung eine Schmelzkleberbeschichtung auf Polyäthylenbasis eingesetzt wird. Als Aufreißband dient eine beiderseits mit einer Polyäthylen-Schmelzkleberbeschichtung versehenes Polyesterband, das auf die Schmelzkleberbeschichtung des Verpackungsmaterials heiß aufgesiegelt wird.The packaging material to be used according to this example differs from that described in example 1 in that instead of the paper web a plastic web, in particular a cellophane web with a basis weight of 28-40 g / m 2 , and instead of the cold adhesive coating, a hot melt adhesive coating based on polyethylene is used. A polyester tape, which is provided on both sides with a polyethylene hot-melt adhesive coating and is hot-sealed onto the hot-melt adhesive coating of the packaging material, serves as the tear tape.
Die Herstellung der Schlauchbeutelpackungen erfolgt wieder so wie anhand von Fig. 1 beschrieben, wobei die Siegelungsnähte im Gegensatz zu Beispiel 1 in Form von Heißsiegelungen ausgeführt werden.The tubular pouch packs are again produced as described with reference to FIG. 1, the sealing seams, in contrast to example 1, being carried out in the form of heat seals.
Die erfindungsgemäße Packung kann in erster Linie vorteilhaft als Packung für Lebensmittel, wie Schokoladen oder Dauerbackwaren eingesetzt werden, die gegebenenfalls gasdicht ausgeführt bzw. in Form von Schlauchbeutelpakkungen hergestellt werden können. Ihre gewerbliche Verwertbarkeit ist dabei jedoch nicht auf Packungen für feste Verpackungsgüter beschränkt.The package according to the invention can primarily be used advantageously as a package for foodstuffs such as chocolates or baked goods that can optionally be made gas-tight or can be produced in the form of tubular pouches. However, their commercial usability is not limited to packs for solid packaging goods.
