Abstract

L'emballage en un matériau plan, en particulier flexible, comprend une enveloppe étanche aux gaz et une languette de déchirement délimitée par des lignes entaillées ou de zones affaiblies (3, 13, 23) où le matériau d'emballage est relié à un élément de couverture (5, 15, 25) en matériau de préférence plan. La surface supérieure (6, 16, 26) de l'élément de couverture (5, 15, 25), connectée de façon plane avec le matériau d'emballage, a une périphérie fermée (7, 17, 27) qui entoure complètement les lignes entaillées (3, 13, 23) sans les toucher. Lorsqu'on tire sur l'élément de couverture (5, 15, 25) formant le début de la languette de déchirement, le matériau d'emballage se déchire à partir des deux extrémités des lignes entaillées ou des zones affaiblies (3, 13, 23) et selon les lignes délimitant une zone de déchirement (4, 14, 24). Des lignes affaiblies supplémentaires (2, 12) peuvent être prévues aux endroits où le matériau d'emballage est destiné à se déchirer. Des matériaux d'emballage à deux couches sans zones affaiblies (2, 12) mais à déchirement reproductible, sont constitués de préférence d'une couche intérieure de support et d'une couche extérieure étanche aux gaz et d'épaisseur le plus souvent réduite.The packaging in a flat, in particular flexible material, comprises a gas-tight envelope and a tear-off tab delimited by notched lines or weakened zones (3, 13, 23) where the packaging material is connected to an element cover (5, 15, 25) of preferably planar material. The upper surface (6, 16, 26) of the cover member (5, 15, 25), connected in a planar manner with the packaging material, has a closed periphery (7, 17, 27) which completely surrounds the notched lines (3, 13, 23) without touching them. When the cover member (5, 15, 25) forming the start of the tear-off tab is pulled, the packaging material tears from both ends of the notched lines or weakened areas (3, 13, 23) and along the lines delimiting a tearing zone (4, 14, 24). Additional weakened lines (2, 12) may be provided where the packaging material is intended to tear. Two-layer packaging materials without weakened areas (2, 12) but with reproducible tearing, preferably consist of an inner support layer and an outer gas-tight layer, most often of reduced thickness.

Description

Packung mit gasdichter Packungshülle. Pack with a gas-tight packing envelope.
Technisches Gebiet;Technical field;
Die Erfindung betrifft eine Packung mit gasdichter Packungshülle, bestehend aus einem flächigen, insbeson dere flexiblen Verpackungsmaterial und einem Aufreißorgan, das dazu bestimmt ist, beim Öffnen der Packung an seinem Anfang angefaßt und in eine vorgegebene Aufreißrichtung gezogen zu werden, wobei das Verpackungsmaterial an der Berandung eines streifen oder lappenförmigen Auf reißbereiches einreißt.The invention relates to a pack with a gas-tight packing envelope, consisting of a flat, in particular flexible packaging material and a tear-open element, which is intended to be touched when the package is opened at the beginning and to be pulled in a predetermined tear-open direction, the packaging material being at the edge a strip or flap-shaped tear on tear area.
Stand der Technik;State of the art;
Eine Packung dieser Art ist aus der veröffentlichten PCT-Anmeldung WO 80/02827 (Anmeldung Nr. PCT/AT 80/00017) der Anmelderin bekannt. Bei dieser bekannten Packung, die vorteilhaft aus einem zweilagigen Verpackungsmaterial hergestellt und/oder als Schlauchbeutelpackung ausgeführt ist, werden die seitlichen Berandungen des Aufreißbereiches durch im Verpackungsmaterial angebrachte Schwächungslinien gebildet, längs denen das Material beim Öffnen der Packung einreißt. Der Anfang der streifenförmigen Aufreißhilfe liegt hierbei in einem Dopplungsbereich des Verpackungsmaterials, bei einer Schlauchbeutelpackung also z.B. an einer ihrer flossenförmigen Siegelungssteilen. Durch an dem Verpeckungsmaterial in dem genannten Dopplungsbereich in besonderer Weise angeordnete Schwächungslinien wird unter Beibehaltung der Gasdichtheit der Packungshülle eine unproblematische Betätigung des Aufreißorgans ermöglicht. Bei der in der oben genannten PCT-Anmeldung beschriebenen Packung mit gasdichter Packungshülle liegt der Aufreißorgananfang an einem Ver packungsmaterial-Dopplungsbereich, also z.B. an den durch Siegelnähte gebildeten Flossen einer Schlauchbeutelpackung. Dies ist natürlich eine Einschränkung für die Anordnung bzw. für die Ausbildung des Aufreißorgans.A pack of this type is known from the published PCT application WO 80/02827 (application no. PCT / AT 80/00017) by the applicant. In this known package, which is advantageously produced from a two-layer packaging material and / or is designed as a tubular bag package, the lateral edges of the tear-open area are formed by lines of weakness in the packaging material, along which the material tears when the package is opened. The beginning of the strip-like tear-open aid here lies in a doubling area of the packaging material, in the case of a tubular bag pack, for example, on one of its fin-shaped sealing parts. By means of weakening lines arranged in a special way on the packaging material in the said doubling area, an unproblematic actuation of the tear-open member is made possible while maintaining the gas tightness of the packing envelope. In the case of the pack with gas-tight packing envelope described in the above-mentioned PCT application, the tear organ start is due to a Ver Packing material duplication area, for example on the fins of a tubular bag pack formed by sealing seams. Of course, this is a restriction for the arrangement or for the formation of the tear-open element.

The carrier layer can advantageously be made from a paper web or a plastic film, while the gas-tight layer can advantageously consist of an aluminum foil or a plastic film.
Kurze Beschreibung der ZeichnungenBrief description of the drawings
Für die anhand der Figuren 1 und 2 beschriebenen Packungen geht man beispielsweise von einem mehrlagigen Verpackungsmaterial aus, das eine an der Packungsaußenseite zu liegen kommende Trägerschicht aus einem getriebenen Kraftpa pier einer Grammatur von 50 - 70 g/m2, eine an diese ankaschierte 0,009 mm starke Aluminiumfolie als gasdichte Schicht und daran anschließend eine Siegelme diumschicht aufweist. Je nach Art der durchzuführenden Siegelung besteht die Siegelmediumschicht vorteilhaft aus einem Heißsiegelmedium, wie einer PE- oder PVDC- oder Hotmelt - Beschichtung einer Stärke von 0,02 bis 0,06 mm oder einer Kaltkleberbeschichtung auf Latex basis mit einem Auftrag von 2 - 7 g/m2 (Feststoff).For the packs described with reference to FIGS. 1 and 2, for example, a multilayer packaging material is assumed, one of which lies on the outside of the pack Coming carrier layer from a driven Kraftpa pier a grammage of 50 - 70 g / m 2 , a 0.009 mm thick aluminum foil laminated to this as a gas-tight layer and then has a sealing medium layer. Depending on the type of sealing to be carried out, the sealing medium layer advantageously consists of a heat-sealing medium, such as a PE or PVDC or hot-melt coating with a thickness of 0.02 to 0.06 mm or a cold adhesive coating based on latex with an application of 2-7 g / m 2 (solid).
Fig. 1 zeigt in perspektivischer Darstellung eine Schlauchbeutelpackung 1 deren Verpackungsmaterial zwei Schwächungslinien 2 aufweist, welche an ihren Enden durch eine im Verpackungsmaterial angebrachte linienförmige Durchstanzung 3 miteinander verbunden sind, derart, daß diese Schwächungslinien 2 und die Durchstanzung 3 einen Aufreißbereich 4 begrenzen.Fig. 1 shows a perspective view of a tubular bag pack 1 whose packaging material has two weakening lines 2, which are connected at their ends by a line-shaped punching 3 attached in the packaging material, such that these weakening lines 2 and the punching 3 limit a tear-open area 4.
Im Bereich dieser Durchstanzung ist das Verpackungsmaterial mit einem flächenhaften Abdeckelement 5 (das in Fig. 1 aus Gründen der Übersichtlichkeit mit übertrieben großer Dicke dargestellt ist) in lösbarer Weise über einen Bereich 6 der Abdeckelementoberfläche verklebt, wobei die äußere Kontur 7 dieses Oberflächenbereichs 6 die Durchstanzung 3 völlig umschließt, diese aber nicht berührt. Durch das Abdeckelement 5 wird die Durchstanzung 3, welche eine Öffnung im. Verpackungsmaterial darstellt, gasdicht verschlossen. Zur Erzielung einer ausreichenden Gasdichtheit beträgt der Mindestabstand der Kontur 7 von der Durchstanzung 3 dabei etwa 5 mm. Das Abdeckelement 5, das z.B. vorteilhaft eine Klebeetikette sein kann, ist ferner an einem Randbereich 8, der den ablaufenden Schwächungslinien gegenüberliegt, mit dem Verpackungsmaterial nicht verklebt.In the area of this punching, the packaging material is releasably glued to a surface covering element 5 (which is shown in FIG. 1 with an excessively large thickness for clarity) over an area 6 of the covering element surface, the outer contour 7 of this surface area 6 being punched through 3 completely encloses, but does not touch them. Through the cover 5, the punch 3, which has an opening in the. Packaging material represents, sealed gas-tight. In order to achieve sufficient gas tightness, the minimum distance of the contour 7 from the punching 3 is about 5 mm. The cover element 5, which can advantageously be an adhesive label, for example, is also on an edge region 8, which lies opposite the running lines of weakness not glued to the packaging material.
Beim Aufreißen der Packung wird das Abdeckelement 5 an seinem Randbereich 8 angefaßt und in Richtung des Pfeiles 9 zunächst vom Verpackungsmaterial abgezogen und dann dem Aufreißbereich 4 entlanggeführt. Das Abdeckelement 5 löst sich dabei nicht vom Aufreißbereichanfang 10, so daß die Packung in üblicher Weise durch Einreißen der Schwächungslinien 2 geöffnet wird. Dabei wird infolge der U-förmigen Durchstanzung 3 bewirkt, daß beim Aufreißvorgang dem Abziehen des Aufreißbereiches 4 kein stärkerer Widerstand entgegensteht und das Einreißen des Verpackungsmaterials an seinen Schwächungslinien 2 zügig und mit geringem Kraftaufwand ausgeführt werden kann.When the package is torn open, the cover element 5 is gripped at its edge area 8 and first pulled off from the packaging material in the direction of arrow 9 and then guided along the tear area 4. The cover element 5 does not detach from the opening area 10, so that the package is opened in the usual way by tearing the lines of weakness 2. As a result of the U-shaped punching 3, there is no greater resistance to the pulling off of the tearing area 4 during the tearing process and the tearing of the packaging material on its weakening lines 2 can be carried out quickly and with little effort.
In manchen Fällen kann nun aber statt der die beiden Schwächungslinien 2 verbindenden linienförmigen Durchstanzung ein insbesondere durch eine Anstanzung realisiertes Schwächungslinienstück vorgesehen werden. Dabei kommt es darauf an, daß die Adhäsion der flächigen Verbindung, mit der das Abdeckelement mit dem Anfang des Aufreißstreifens verbunden Ist, groß genug ist, um die Kraft, die zum Aufreißen des Verpackungsmaterials an den die beiden Schwächungslinien 2 verbindenden Schwächungsllnienstücke benötigt wird, zu übertragen. Da bei diesen Packungsvarianten keine Durchstanzung vorgesehen ist, verliert das Abdeckelement seine Dichtungsfunktion und es genügt, wenn das Abdeckelement ausschließlich im Aufreißbereich-Anfang mit dem Verpackungsmaterial flächig verbunden ist.In some cases, however, instead of the line-shaped punching that connects the two weakening lines 2, a piece of weakening line that is realized in particular by punching can be provided. It is important that the adhesion of the flat connection with which the cover element is connected to the start of the tear strip is large enough to the force required to tear the packaging material on the weakening line pieces connecting the two weakening lines 2 transfer. Since no punching is provided in these pack variants, the cover element loses its sealing function and it is sufficient if the cover element is connected to the packaging material only at the beginning of the tear-open area.
Fig. 2 zeigt eine Schlauchbeutelpackung 11, die analog wie die Packung gemäß Fig.1 einen Aufreißbereich 14 aufweist, der von Schwächungslinien 12 und einer diese Schwächungslinien verbindenden Durchstanzung 13 begrenzt wird. Bei die ser Packungsvariante Ist nun ein flächiges Abdeckelement 15 im Bereich der Durchstanzung 13 auf der Innenseite des Verpackungsmaterials aufgeklebt. Der bei dieser Verklebung mit dem Verpackungsmaterial flächig ver bundene Oberflächenbereich 16 des Abdeckelements 15 ist fensterförmig ausgebildet, d.h. er weist neben einer äußeren Kontur 17 eine die Fensteröffnung begrenzende innere Kontur 18 auf, innerhalb der das Abdeckeiement 15 mit dem Verpackungsmaterial nicht verklebt ist. Der Min destabstand dieser inneren Kontur 18 von der äußeren Kontur 17 beträgt dabei etwa 5 mm. Durch das Abdeckele ment 15 ist nun in ähnlicher Weise wie bei der Packung gemäß Fig. 1 die durch die Durchstanzung 13 gebildete Öffnung im Verpackungsmaterial gasdicht verschlossen. Da bei der vorliegenden Packung gemäß Fig. 2 das Abdeckelement 15 im Bereich der Durchstanzung 13 nicht mit dem Verpackungsmaterial verklebt ist, bildet der Aufreißbereich-Anfang 20 einen leicht abhebbaren Verpackungsmaterial lappen.FIG. 2 shows a tubular bag pack 11 which, like the pack according to FIG. 1, has a tear-open area 14 which is delimited by weakening lines 12 and a punching 13 connecting these weakening lines. At the This packaging variant is now a flat cover element 15 glued in the punched area 13 on the inside of the packaging material. The surface area 16 of the cover element 15, which is connected to the packaging material in a flat manner in this way, is window-shaped, ie it has, in addition to an outer contour 17, an inner contour 18 which delimits the window opening, within which the covering element 15 is not glued to the packaging material. The minimum distance of this inner contour 18 from the outer contour 17 is about 5 mm. Through the cover element 15, the opening formed by the punching 13 in the packaging material is now closed in a gas-tight manner in a similar manner to the packing according to FIG. 1. Since the cover element 15 in the present punching according to FIG. 2 is not glued to the packaging material in the area of the punching 13, the opening area 20 forms a packaging material which can be easily lifted off.
Beim Aufreißen der Packung wird der Aufreißbereich 14 an seinem Anfang 20 angefaßt und unter Eiureißung der Schwächungslinien 12 und Ablösung von dem an der Verpackungsmaterialinnenseite angebrachten Abdeckelement 15 In Richtung des Pfeiles 19 abgezogen.When the package is torn open, the tear-open area 14 is grasped at its start 20 and pulled off in the direction of arrow 19, tearing the lines of weakness 12 and detaching it from the cover element 15 attached to the inside of the packaging material.
An den beiden anhand der Figuren 1 und 2 beschriebenenOn the two described with reference to Figures 1 and 2
Packungsvarianten nehmen die Aufreißbereiche jeweils einen relativ großen Teil der Packungsfrontoberfläche ein.Packing variants each take up a relatively large part of the front surface of the pack.
Um diese Aufreißhilfen aus ästhetischen Gründen bzw. zum Schutz gegen etwaige mechanische Beschädigungen abzudecken, kann der prismaförmige Hüllenbereich dieser Packungen vor teilhaft mit einer nachträglich angebrachten hülsenformigen Schleife aus flächigem Material, wie Papier, versehen werden. Auf diese Schleife wird dann - unbeeinträchtigt durch die Ausbildung der Aufreißhilfe - die äußere Aufmachung der Packung angebracht. Es kann aber auch bei einer Packung wie nach Fig. 1 die hülsenförmige Schleife vorteilhaft so ausgebildet sein, daß sie gleichzeltig das Abdeckelement bildet.In order to cover these tear-open aids for aesthetic reasons or to protect against any mechanical damage, the prism-shaped envelope area of these packs can be used partially with a subsequently attached sleeve-shaped loop made of flat material, such as paper. The outer packaging of the pack is then attached to this loop, unaffected by the design of the tear-open aid. 1, the sleeve-shaped loop can advantageously also be designed in such a way that it forms the cover element at the same time.
Es hat sich gezeigt, daß das Aufreißorgan der erfindungsgemäßen Packung in vielen Fällen auch dann in gut reproduzierbarer Weise funktioniert, wenn der Aufreißbereich seitlich nicht durch Schwächungslinien begrenzt ist. In diesen Fällen reißt das Verpackungsmaterial von den beiden Enden der Durchstanzung ausgehend längs zwei im wesentlichen parallel bzw. leicht konvergierenden oder leicht divergierenden Linien ein. Dies ist z.B. der Fall, wenn das Verpackungsmaterial aus bestimmten einlagigen Materialien wie Papier, einem biaxial gereckten Polypropylen (OPP) oder einer Aluminiumfolie besteht. Beim Einsatz von mehrlagigen Verpackungsmaterialien, wie sie bevorzugt zum Aufbau von gasdichten Packungen, wie Schlauchbeutelpackungen verwendet werden, zeigt sich aber ein differenziertes Einreißverhalten.It has been shown that the tear-open member of the package according to the invention in many cases also functions in a reproducible manner if the tear-open area is not laterally limited by lines of weakness. In these cases, the packaging material tears from the two ends of the punching along two substantially parallel or slightly converging or slightly divergent lines. This is e.g. the case when the packaging material consists of certain single-layer materials such as paper, a biaxially oriented polypropylene (OPP) or an aluminum foil. When using multi-layer packaging materials, as they are preferably used to build gas-tight packs, such as tubular bag packs, there is a differentiated tear behavior.
Bei Verpackungsmaterialien, die eine Trägerschicht und eine mit dieser verbundenen gasdichten Schicht aus einem homogenen, gasdichten, jedoch gut elnreißfähigem Material aufweisen, welche Schichten bei der Herstellung durch bahnenförmige Lagen gebildet werden, zeigt sich - insbesondere bei einem raschen Aufreißen der Packungen - in der Regel nur dann ein gut reproduzierendes, nicht zu stark divergierendes oder keilförmig zusammenlaufendes Einreißen des Ver packungsmaterials, wenn das Trägermaterial dem Packungsgut zugewandt ist.In the case of packaging materials that have a carrier layer and a gas-tight layer made of a homogeneous, gas-tight, but easily tearable material, which layers are formed during the production by sheet-like layers, it is usually shown - especially when the packs are torn open quickly only then a well reproducing, not too divergent or wedge-shaped tearing of the ver packing material, if the carrier material faces the packaged goods.
Ein solches Verpackungsmaterial, welches dreischichtig aufgebaut ist, besteht z.B. - von der Packungsaußenseite ausgehend - aus einer 0,012 bis 0,020 mm starken Folie aus biaxial gerecktem Polypropylen (OPP), einer 0,009 mm starken Aluminiumfolie, einem Kraftpapier einer Grammatur von 40 - 60 g/m2 und einer Kaltkleberbe schichtung auf Latexbasis (2 - 7 g/m2 Feststoff).Such packaging material, which has a three-layer structure, consists, for example - from the outside of the pack - of a 0.012 to 0.020 mm thick film made of biaxially stretched polypropylene (OPP), a 0.009 mm thick aluminum film, a kraft paper with a grammage of 40 - 60 g / m 2 and a cold adhesive coating based on latex (2 - 7 g / m 2 solid).
Die Fig.3 zeigt in perspektivischer Darstellung eine z.B. mit einem solchen Verpackungsmaterial hergestellte, als Schlauchbeutelpackung ausgebildete erfindungsgemäße Packung, bei der keine Schwächungslinien vorgesehen sind.3 shows a perspective view of e.g. Pack according to the invention produced with such a packaging material and designed as a tubular bag pack, in which no lines of weakness are provided.
Das Verpackungsmaterial weist hier eine U-förmige Durch stanzung 33 auf, die mit einer partiell mit Klebstoff beschichteten Klebeetikette als Abdeckelement 25 wieder verschlossen ist. Die äußere Kontur 27 des Klebeberelches 26 des Abdeckelementes 25 umschließt dabei die Durchstanzung 23 völlig,ohne sie jedoch zu berühren. Das Abdeckelement 25 weist ferner einen Randbereich 28 auf, mit dem es mit dem Verpackungsmaterial nicht verbunden ist.The packaging material here has a U-shaped punching 33, which is closed again with a partially coated with adhesive label as a cover element 25. The outer contour 27 of the adhesive area 26 of the cover element 25 completely surrounds the punched hole 23 without, however, touching it. The cover element 25 also has an edge region 28 with which it is not connected to the packaging material.
Beim Aufreißen der Packung wird das Abdeckelement 25 angefaßt und in Richtung des Pfeiles 29 abgezogen. Dabei reißt das Verpackungsmaterial längs zwei zueinander angenähert parallel verlaufenden Linien, die den Aufreißberelch 24 zu beiden Seiten begrenzen, ein. Fig. 4 zeigt die Packung während des AufreißVorganges in einer Teildarstellung im Schnitt. Verwendet man bei einer Packung gemäß den Figuren 3 und 4 hingegen ein Verpackungsmaterial,welches - von außen nach innen - eine OPP-Folie, ein Kraftpapier, eine Aluιminimfolie und schüeßlich die Kaltkleberbeschlchtung(jeweils z.B. in den Einzelstärken wie im Zusammenhang mit Fig. 3 angegeben) aufweist, so laufen - insbesondere bei einem raschen Aufreißen der Packung - die Einreißlinien keilförmig zusammen, so daß sich keine zur Entnahme von Verpackungsgut brauchbare Öffnung bildet.When the package is torn open, the cover element 25 is gripped and pulled off in the direction of the arrow 29. The packaging material tears along two lines running approximately parallel to one another and delimiting the tear-open area 24 on both sides. Fig. 4 shows the pack during the tear process in a partial view in section. If, on the other hand, a packaging according to FIGS. 3 and 4 is used, a packaging material which - from the outside inwards - contains an OPP film, a kraft paper, an aluminum foil and finally the cold adhesive coating (in each case, for example, in the individual thicknesses as indicated in connection with FIG. 3), the tearing lines run together in a wedge shape, in particular when the package is torn open quickly, so that no opening that can be used to remove packaging material is formed.
Ein zweilagiges Verpackungsmaterial, das für erfindungsgemäße Packungen, welche ohne den Aufreißbereich seitlich begrenzende Schwächungsllnien auskommen, geeignet ist, besteht außerdem z.B. - von außen, nach innen - aus einer Aluminiumfolie, einem gestrichenen Kraftpapier und derThere is also a two-layer packaging material which is suitable for packs according to the invention which do not require weakening lines which laterally delimit the tear-open area, e.g. - from the outside, inside - from an aluminum foil, a coated kraft paper and the
Kaltkleberbeschichtung,und zwar jeweils mit Einzelstärken, wie sie z.B. bei dem im Zusammenhang mit den Figuren 1 und 2 verwendeten Verpackungsmaterial angegeben sind.Cold adhesive coating, each with individual thicknesses, such as those e.g. are indicated in the packaging material used in connection with FIGS. 1 and 2.
Andere geeignete zweilagige Verpackungsmateriallen bestehen z.B. - jeweils von außen nach Innen - aus einer 0,012 bis 0,030 mm starken OPP-Folie, einer 0,02 bis 0,04 mm starken PE-Folie und einer Kaltkleberbeschichtung oder aus einer 0,009 mm starken Aluminiumfolie, einer 0,02 - 0,03 mm starken OPP-Folie und der Kaltkleberbeschichtung. Im ersteren Fall bildet die PE-Folie und im zweiten Fall die OPP-Folie die (stärkere) Tragerschiebt.Other suitable two-layer packaging materials are e.g. - in each case from the outside inwards - from a 0.012 to 0.030 mm thick OPP film, a 0.02 to 0.04 mm thick PE film and a cold adhesive coating or from a 0.009 mm thick aluminum film, a 0.02 - 0.03 mm thick OPP film and the cold adhesive coating. In the former case, the PE film and in the second case, the OPP film forms the (stronger) slide.
Gewerbliche VerwertbarkeitCommercial usability
Die erfindungsgemäße gasdichte Packung kann in erster Linie vorteilhaft als Packung für Lebensmittel, wie Schokoladen oder Dauerbackwaren elngeeetzt werden und wird gegebenenfalls in Form einer Schlauchbeutelpackung hergestellt. Ihre gewerbliche Verwertbarkeit Ist jedoch nicht auf Packungen für feste Verpackungsgüter beschränkt. The gas-tight package according to the invention can primarily be advantageously used as a package for foods such as chocolates or baked goods and is optionally produced in the form of a tubular bag package. However, their commercial usability is not limited to packages for solid packaging goods.
