Description

Die Erfindung betrifft einen Beutel mit den Merkmalen im Oberbegriff von Anspruch 1. Insbesondere bezieht sich die Erfindung auf einen sog. Snack-Beutel.The invention relates to a bag having the features in the preamble of claim 1. In particular, the invention relates to a so-called snack bag.

In weiter Verbreitung kommen solche Beutel als funktionale Verpackung für Nahrungsmittel zum Einsatz, die als Snacks in der Regel für einen unmittelbaren Verzehr aus dem Beutel heraus bestimmt sind. Vielfach dienen diese Beutel der Aufnahme von Snacks, wie belegten Brötchen, Pizzaschnitten, Hamburger, Bagels, Donuts und anderes mehr. Die Beutel werden von der Verkäuferseite her beispielsweise in Bäckereien, Supermärkten oder Tankstellen befüllt oder auch als Bestandteile von Lunchpaketen an Fluggäste oder Schiffspassagiere abgegeben. Wegen der weiten Verbreitung, die die Snack-Beutel gefunden haben, ergeben sich bei der Herstellung beachtlich hohe Stückzahlen, so dass von der Herstellerseite her niedrige Fertigungskosten anzustreben sind. Des Weiteren sollen derartige Beutel, obwohl sie einen sicheren Einschluss des Inhalts gewährleisten, vom Benutzer einfach und bequem für die Entnahme des Inhalts handhabbar sein.Such bags are widely used as a functional food packaging that is typically intended as snacks for immediate consumption out of the bag. In many cases, these bags are used to hold snacks, such as sandwiches, pizza slices, hamburger, bagels, donuts and more. The bags are filled from the seller side, for example, in bakeries, supermarkets or gas stations or delivered as components of packed lunches to passengers or ship passengers. Due to the widespread use of the snack bags, the production yields considerable quantities, which means that manufacturing costs must be low. Furthermore, while providing secure containment of the contents, such bags are to be easily and conveniently handled by the user for removal of the contents.

Die DE 89 05 639 , die US 2007/0258662 A1 , die US 2007/0080197 A1 und die US 2005/0139508 A1 beschreiben jeweils einen gattungsgemäßen Beutel, bestehend aus mindestens zwei Folienflächen, die randseitig unter Freilassen einer Beutelöffnung und eines Beutel-Aufnahmeraums zumindest teilweise miteinander verbunden sind, wobei zumindest eine der Folienflächen derart mit einer Perforation versehen ist, dass bei deren Auftrennen zumindest ein Folienteil diese Folienfläche unter Freigabe des Beutel-Aufnahmeraums unterbricht.The DE 89 05 639 , the US 2007/0258662 A1 , the US 2007/0080197 A1 and the US 2005/0139508 A1 each describe a generic bag, consisting of at least two film surfaces, the edge below Releasing a bag opening and a bag-receiving space are at least partially connected to each other, wherein at least one of the film surfaces is provided with a perforation such that when they are separated at least one film part interrupts this film surface to release the bag-receiving space.

Im Hinblick auf diese Problematik stellt sich die Erfindung die Aufgabe, einen Beutel zur Verfügung zu stellen, der den sowohl an die Herstellung als auch an die Benutzung zu stellenden Anforderungen in besonderem Maße gerecht wird.In view of this problem, the invention has the object to provide a bag available that will meet the requirements to be placed on both the production as well as the use to a particular extent.

Erfindungsgemäß ist diese Aufgabe durch einen Beutel gelöst, der die Merkmale des Patentanspruchs 1 in seiner Gesamtheit aufweist.According to the invention this object is achieved by a bag having the features of claim 1 in its entirety.

Gemäß dem kennzeichnenden Teil des Anspruchs 1 besteht eine wesentliche Besonderheit der Erfindung darin, dass sich die Perforation H-förmig oder kreuzförmig in Form eines x-förmigen Kreuzes über die eine Folienfläche erstreckt.According to the characterizing part of claim 1, a significant feature of the invention is that the perforation extends H-shaped or cross-shaped in the form of an X-shaped cross over the one film surface.

Die Anordnung kann mit Vorteil so getroffen sein, dass sich bei der H-förmig ausgebildeten Perforation eine Perforationslinie parallel zu den Beutel-Längsrändern und mittig auf der einen Folienfläche erstreckt und das jeweilige Ende dieser Perforationslinie in eine parallel zur Beutelöffnung sich erstreckende Perforationslinie übergeht, die jeweils bis zu den Längsrändern reicht. Dadurch lässt sich im voll geöffneten Zustand des Beutels ein Tablett ausbilden, dessen Fläche der Gesamtsumme der Flächenteile der einen Folienfläche zuzüglich der Gesamtfläche der anderen Folienfläche entspricht.The arrangement may advantageously be such that, in the case of the H-shaped perforation, a perforation line extends parallel to the longitudinal edges of the bag and centrally on one film surface and the respective end of this perforation line merges into a perforation line extending parallel to the opening of the bag each extends to the longitudinal edges. As a result, in the fully opened state of the bag, a tray can be formed whose surface corresponds to the total sum of the surface parts of one film surface plus the total surface area of the other film surface.

Es ist ferner vorgesehen, dass zumindest eine der Folienflächen derart mit einer Perforation versehen ist, dass bei deren Auftrennen zumindest ein Folienteil diese Folienfläche unter Freigabe des Beutel-Aufnahmeraums unterbricht. Durch die Perforation mindestens einer der Folienflächen, die das Auftrennen und damit das Öffnen des Aufnahmeraums innerhalb einer Folienfläche ermöglicht, steht ein Beutel zur Verfügung, der nicht nur aus einem Folienmaterial, wie einer Polyethylenfolie, besonders rationell und kostengünstig herstellbar ist, sondern der dem Benutzer eine besonders einfache und bequeme Entnahme des Behälterinhalts ermöglicht, weil der Aufnahmeraum nicht nur über die Beutelöffnung, sondern auch durch Auftrennen der Perforation innerhalb einer Folienfläche zugänglich ist. Für die Entnahme steht daher ein großflächiger Bereich zur Verfügung, so dass der Inhalt nicht nur durch Herausziehen aus der Beutelöffnung entnehmbar ist.It is furthermore provided that at least one of the film surfaces is provided with a perforation in such a way that, when severed, at least one film part interrupts this film surface, releasing the bag-receiving space. Due to the perforation of at least one of the film surfaces that the Separating and thus allowing the opening of the receiving space within a film surface, a bag is available, which is not only made of a film material, such as a polyethylene film, particularly efficient and inexpensive to produce, but allows the user a particularly simple and convenient removal of the container contents, because the receiving space is accessible not only through the bag opening, but also by separating the perforation within a film surface. For the removal, therefore, a large area is available, so that the content can be removed not only by pulling out of the bag opening.

Mit Vorteil kann die Anordnung so getroffen sein, dass bei einem Beutel, bei dem die eine Folienfläche die Vorderseite und die andere Folienfläche die Rückseite des Beutels bildet, beim Auftrennen der Perforation der einen Folienfläche zumindest ein Folienteil dieser Folienfläche, das aufgestellt und umgelegt ist, die andere Folienfläche, in diesem Fall die Rückseite des Beutels, um ein seine Fläche vergrößerndes Flächenstück ergänzt.Advantageously, the arrangement can be such that, in the case of a bag in which the one side of the film forms the front side and the other side of the bag forms at least one part of the film that has been set up and folded over, when separating the perforation of the one side of the film, the other film surface, in this case the back of the bag, is supplemented by a surface area increasing its area.

Mit besonderem Vorteil kann die Anordnung hierbei so getroffen sein, dass die beiden Folienflächen entlang von parallel zueinander verlaufenden Längsrändern miteinander verbunden sind, entlang denen das jeweilige aufgetrennte und aufgestellte Folienteil der ersten Folienfläche derart umlegbar ist, dass es einen Fortsatz der anderen Folienfläche bildet. Zusammen mit der Behälterrückseite ist daher eine vergrößerte Auflagefläche für den freigelegten Beutelinhalt ausbildbar.Particularly advantageously, the arrangement may be made such that the two film surfaces are connected along mutually parallel longitudinal edges along which the respective separated and erected film part of the first film surface is such that it forms an extension of the other film surface. Together with the container rear side therefore an enlarged support surface for the exposed bag contents can be formed.

In besonders vorteilhafter Weise kann beim Ablegen der anderen Folienfläche, als der Beutelrückseite, auf einer Ebene das jeweils umgelegte Folienteil der einen, also der vorderen, Folienfläche mit der anderen Folienfläche im Wesentlichen gleichfalls eine Ebene ausbilden. Der Benutzer kann dadurch mit dem geöffneten Beutel eine Art Tablett formen, das für den Verzehr des Inhalts an Örtlichkeiten, an denen keine Einrichtung, wie ein Tisch oder dergleichen, zur Verfügung steht, beispielsweise bei einem Aufenthalt des Benutzers im Freien, eine saubere Unterlage für den Verzehr des Snacks bildet.In a particularly advantageous manner, when depositing the other film surface, as the bag back, on one level, the respective folded film part of one, so the front, film surface with the other film surface substantially also form a plane. The user can thereby use the opened bag to form a kind of tray suitable for the consumption of the contents at locations where no device such as a Table or the like, is available, for example, during a stay of the user outdoors, forms a clean surface for the consumption of the snack.

Bei besonders vorteilhaften Ausführungsbeispielen kann parallel zur Beutelöffnung verlaufend der Klebstreifen angeordnet sein, der von einem ablösbaren Abdeckband abgedeckt ist und durch den das weitere umlegbare Folienteil der anderen Folienfläche an der einen Folienfläche befestigbar ist. Durch die Möglichkeit des Wiederverschlusses hat der Benutzer die Möglichkeit, den Snack für einen Teilverzehr über die Beutelöffnung zu entnehmen und den restlichen Teil für späteren Verzehr im geschlossenen Beutel aufzubewahren.In particularly advantageous embodiments, the adhesive strip running parallel to the opening of the bag can be arranged, which is covered by a removable cover strip and by which the further foldable film part of the other film surface can be fastened to the one film surface. The possibility of reclosing allows the user to take the snack for partial consumption through the bag opening and store the remaining portion in a closed bag for later consumption.

In besonders vorteilhafter Weise kann das freie Ende des weiteren umlegbaren Folienteils der anderen Folienfläche im ebenen Zustand in eine Perforationslinie ausmünden, an die sich ein Abreißstreifen als Teil der anderen Folienfläche anschließt, der über Aufnahmeöffnungen verfügt, mit denen sich ein gestapelter Vorrat der Beutel zwecks Vereinzeln an Kunststoffhülsen einer Abgabeeinrichtung für solche Beutel fixieren lässt. Dadurch erleichtert sich das schnelle und einfache Bestücken der Beutel, die für das Verpacken der Snacks seitens des Bäckers oder eines anderen Bestückers einfach von dem an den Aufnahmehülsen hängenden Abreißstreifen abgerissen werden können.In a particularly advantageous manner, the free end of the further foldable film part of the other film surface in the planar state lead to a perforation, which is followed by a tear strip as part of the other film surface, which has receiving openings with which a stacked supply of bags for the purpose of separating to fix plastic sleeves of a dispenser for such bag. This facilitates the quick and easy loading of the bags, which can be easily demolished by the baker or another mounter for the packaging of snacks from the hanging on the receiving sleeves tear strips.

Mit Vorteil können benachbart zu den Längsrändern und parallel zu diesen verlaufend in zumindest einer Folienfläche Belüftungslöcher eingebracht sein. Dadurch kann der Snack "atmen" und bleibt so länger frisch, während die Verpackung trotz einiger vorhandener Belüftungslöcher fett- und feuchtigkeitsundurchlässig und dadurch "tropfsicher" verbleibt.Advantageously, adjacent to the longitudinal edges and running parallel to these ventilation holes may be introduced in at least one film surface. This allows the snack to "breathe" and stay fresh longer, while the packaging, despite some existing ventilation holes fat and moisture impermeable and thus "drip-proof" remains.

Für die Aufnahme von Verzehrgut, wie Snacks oder vorzugsweise belegten Brötchen, sind die Folienflächen vorzugsweise rechteckförmig. Bei Ausbildung des Beutels aus durchsichtigem Kunststoffmaterial, vorzugsweise aus durchsichtigem Polyethylenmaterial niedriger Dichte (LDPE), ist durch eine 100%ige Visibilität die optimale Präsentation des im Beutel befindlichen Snacks für den Kunden gewährleistet.For receiving food, such as snacks or preferably sandwiches, the film surfaces are preferably rectangular. In forming the bag of clear plastic material, preferably of transparent low density polyethylene (LDPE), the 100% visibility ensures optimal presentation of the snack in the bag to the customer.

Die hohlen Aufnahmehülsen 4 lassen sich an gabel- oder zinkenförmigen Halteteilen (nicht dargestellt), die an einer Wand im Verkaufsraum stationär angeordnet sind, mit dem Beutelverbund 2 gemäß der Darstellung nach der Fig. 1 gemeinsam aufhängen, so dass bei Verbrauch der Beutel die Aufnahmehülsen 4 sich mit den verbliebenen Streifenresten 18 als Abfall von den Halteteilen entfernen lassen, und ein neuer Beutelstapel 2 lässt sich dann mit seinem Paar Aufnahmehülsen 4 über die Halteteile an der Wand für weitere Beutel-Abreißvorgänge festlegen. Die Beutel können aber auch anders, beispielsweise an einer Ladentheke, festgelegt werden oder für eine Einzelverwendung vorgesehen sein, wobei dann die Aufnahmehülsen 4 mit dem oberen Streifen 18 auch ganz entfallen können.The Fig. 1 shows a stack 2 unpatterned bag, which consist of a plastic film material. The stack 2 is suspended on two receiving sleeves 4, one of which in the 8 and 9 is shown separately. These receiving sleeves 4, which are preferably made of a thermosetting plastic, starting from a round foot part 6 starting a cylindrical, hollow receiving shaft 8, at the free end of a cap 10 can be fastened by clipping. The hollow receiving sleeves 4 can be at forked or tine-shaped holding parts (not shown), which are arranged stationary on a wall in the sales room, with the bag composite 2 as shown in the Fig. 1 hang together so that when consumption of the bags, the receiving sleeves 4 can be removed with the remaining remnants 18 as waste from the holding parts, and a new bag stack 2 can then be with his pair of receptacles 4 on the holding parts on the wall for further bag tear-off operations establish. The bags can also be different, for example, at a shop counter, set or be provided for a single use, in which case the receiving sleeves 4 with the upper strip 18 can be omitted entirely.

Das Folienmaterial der Beutel besteht beim vorliegenden Ausführungsbeispiel aus dünnem Polyethylenmaterial niedriger Dichte (LDPE), wobei zur Bildung eines im Umriss rechteckförmigen Beutels eine erste Folienfläche 12, die die Beutelvorderseite bildet, und eine zweite Folienfläche 14 vorgesehen sind, die, siehe Fig. 3, die Beutelrückseite bildet. Diese zweite Folienfläche 14 hat eine Rechteckform der gleichen Breite wie die erste Folienfläche 12, ist jedoch demgegenüber um ein Klappenteil 16 verlängert, an das sich wiederum ein Abreißstreifen 18 anschließt. Dieser weist für jede Aufnahmehülse 4 eine Aufnahmeöffnung 20 auf. Eine zwischen Abreißstreifen 18 und Klappenteil 16 verlaufende Perforationslinie 22 ermöglicht ein bequemes Entnehmen eines Beutels vom aufgehängten Beutelstapel 2 durch Abreißen an der Perforationslinie 22.The film material of the bags in the present embodiment consists of thin low density polyethylene (LDPE) material, to form an outline rectangular bag, a first film surface 12 forming the bag front side and a second film surface 14 are provided, see Fig. 3 making bag back. This second foil surface 14 has a rectangular shape of the same width as the first foil surface 12, but in contrast is extended by a flap member 16, which in turn is followed by a tear strip 18. This has a receiving opening 20 for each receiving sleeve 4. A perforation line 22 running between tear-off strips 18 and flap part 16 allows convenient removal of a bag from the suspended bag stack 2 by tearing off at the perforation line 22.

Erste Folienfläche 12 und zweite Folienfläche 14 sind entlang der in Fig.1 bis 5 vertikal verlaufenden Längsränder 24 sowie entlang einem den Beutelboden bildenden Endrand 26 miteinander verbunden, so dass zwischen erster Folienfläche 12 und zweiter Folienfläche 14 ein Aufnahmeraum 40 (siehe Fig. 5) gebildet ist, wobei sich am oberen Rand der ersten Folienfläche 12 eine Beutelöffnung 28 befindet, die gemäß der Darstellung nach der Fig. 5 jedoch von dem Klappenteil 16 als weiterem Folienteil durch Umklappen desselben auf die Beutelvorderseite verschlossen ist. Ferner ist die Beutelöffnung 28 auf der rückwärtigen Seite des Beutels von der hinteren Folienfläche 14 begrenzt. Hierfür ist von der Beutelöffnung 28 in Richtung auf den unteren Endrand 26 hin um eine Strecke versetzt, die etwas geringer als die Breite des Klappenteils 16 der hinteren, zweiten Folienfläche 14 ist, über die gesamte Breite der ersten Folienfläche 12 ein Klebstreifen 30 aufgetragen, der von einem ablösbaren Abdeckband 32 bedeckt ist. Nach dem Ablösen des Abdeckbandes 32, wie es in Fig. 4 angedeutet ist, wo der Beginn des Ablösens dargestellt ist, ist das Klappenteil 16 am Rand der Beutelöffnung 28 umklappbar und an den Klebstreifen 30 anklebbar, so dass, wie in Fig. 5 dargestellt ist, ein die Beutelöffnung 28 verschließender Adhäsionsverschluss gebildet ist, der bei Bedarf wieder geöffnet werden kann.First film surface 12 and second film surface 14 are along the in Fig.1 to 5 vertically extending longitudinal edges 24 and along an end edge 26 forming the bag bottom, so that between the first film surface 12 and second film surface 14 a receiving space 40 (see Fig. 5 ) is formed, wherein at the upper edge of the first film surface 12 is a bag opening 28 which, according to the illustration of the Fig. 5 However, it is closed by the flap part 16 as a further film part by folding over the same on the bag front side. Furthermore, the bag opening 28 on the rear side of the bag is bounded by the rear film surface 14. For this purpose, offset from the bag opening 28 in the direction of the lower end edge 26 by a distance which is slightly smaller than the width of the flap portion 16 of the rear, second film surface 14, applied over the entire width of the first film surface 12, an adhesive strip 30, the is covered by a removable cover tape 32. After detaching the cover band 32, as shown in FIG Fig. 4 is indicated where the beginning of the detachment is shown, the flap member 16 at the edge of the bag opening 28 can be folded and adhered to the adhesive strip 30, so that, as in Fig. 5 is shown, the bag opening 28 occlusive adhesive closure is formed, which can be opened again when needed.

Der erfindungsgemäße Beutel ist nicht nur durch Lösen des Adhäsionsverschlusses an der Beutelöffnung 28 zu öffnen, sondern ermöglicht es, durch Öffnen der ersten Folienfläche 12 einen großflächigen, bequemen Zugang zum Beutel-Aufnahmeraum 40 zu bilden. Hierfür ist die erste Folienfläche 12 mit einer Anordnung von Perforationen versehen, wobei beim gezeigten Ausführungsbeispiel eine H-förmige Perforation gebildet ist, die eine erste Perforationslinie 34 aufweist, die sich in Vertikalrichtung, also zu den Längsrändern 24 parallel verlaufend, in der Folienfläche 12 mittig erstreckt. An das untere Ende der ersten Perforationslinie 34, das sich in geringem Abstand vom unteren Endrand 26 befindet, schließt sich eine zweite Perforationslinie 36 an, die sich zum Endrand 26 parallel verlaufend bis zu den seitlichen Längsrändern 24 erstreckt. Am gegenüberliegenden oberen Ende der ersten Perforationslinie 34 schließt sich eine dritte Perforationslinie 38 an, die sich, zur zweiten Perforationslinie 36 parallel verlaufend, bis zu den beiden Längsrändern 24 erstreckt und sich vom Klebstreifen 30 in einem Abstand befindet, der in etwa dem Abstand der zweiten Perforationslinie 36 vom unteren Endrand 26 entspricht. Wie in Fig. 5 verdeutlicht, wo der Beginn eines Öffnungsvorgangs gezeigt ist, lässt sich durch Auftrennen der Perforationslinien 34, 36, 38 ein großflächiger Zugang zum Beutel-Aufnahmeraum 40 ausbilden.The bag according to the invention can be opened not only by releasing the adhesive closure at the bag opening 28, but also makes it possible to form a large-area, convenient access to the bag receiving space 40 by opening the first film surface 12. This is the first foil surface 12 provided with an array of perforations, wherein in the embodiment shown an H-shaped perforation is formed, which has a first perforation 34 which extends in the vertical direction, ie parallel to the longitudinal edges 24, in the film surface 12 centered. At the lower end of the first perforation line 34, which is located at a small distance from the lower end edge 26, is followed by a second perforation line 36 which extends parallel to the end edge 26 to the lateral longitudinal edges 24. At the opposite upper end of the first perforation line 34 is followed by a third perforation line 38 which extends parallel to the second perforation line 36 to the two longitudinal edges 24 and is spaced from the adhesive strip 30, which is approximately the distance of the second Perforation line 36 from the lower end edge 26 corresponds. As in Fig. 5 illustrates where the beginning of an opening operation is shown, can be formed by separating the perforation lines 34, 36, 38 a large area access to the bag-receiving space 40.

Nach vollständiger Trennung der Perforationslinien 34, 36 und 38 sind die Folienteile 42 und 44 frei, um aufgestellt und um die seitlichen Längsränder 24 umgelegt zu werden, so dass sich die Folienteile 42 und 44 der ersten, vorderen Folienfläche 12 seitlich über den Bereich der hinteren, zweiten Folienfläche 14 hinaus erstrecken, siehe Fig. 6 und 7, wo der ausgebreitete Zustand in Vorderansicht bzw. Rückansicht gezeigt ist. Wie ersichtlich, ist dadurch eine Art Tablett mit freiliegendem Beutel-Aufnahmeraum 40 gebildet, das als ebene Verzehrfläche dienen kann, wenn der so geöffnete Beutel mit der in Fig. 7 sichtbaren Rückseite auf eine ebene Unterlage aufgelegt ist.After complete separation of the perforation lines 34, 36 and 38, the film parts 42 and 44 are free to be set up and folded around the lateral longitudinal edges 24, so that the film parts 42 and 44 of the first, front film surface 12 laterally over the region of the rear , second foil surface 14, see Fig. 6 and 7 where the expanded state is shown in front view and rear view, respectively. As can be seen, this is a kind of tray with exposed bag-receiving space 40 is formed, which can serve as a flat eating surface when the thus opened bag with the in Fig. 7 visible back is placed on a flat surface.

Ein besonders guter Öffnungsvorgang für die vordere Beutelseite lässt sich auch erreichen, wenn man die Perforationslinie 34 entgegen der Darstellung nach der Fig. 4 nicht an ihrem oberen Ende an der Perforationslinie 38 öffnet, sondern vielmehr mittig, so dass zunächst die mittlere Perforationslinie 34 durchreißt, wobei damit nahezu zeitglich die beiden Folienteile 42, 44 entlang der beiden Perforationslinien 36, 38 umgelegt und unter Bildung der Tablettfläche nach den Figuren 6 und 7 aufgeklappt werden.A particularly good opening process for the front side of the bag can also be achieved if the perforation line 34 is opposite to the representation of the Fig. 4 does not open at its upper end on the perforation line 38, but rather in the middle, so that initially the middle perforation line 34 breaks through, whereby the two film parts 42 44 along the two perforation lines 36, 38 folded over and forming the tray surface after the FIGS. 6 and 7 be unfolded.

Da gemäß der Darstellung nach den Figuren 3 und 6 die obere Perforationslinie 38 sich auch über die hintere Folienfläche 14 erstreckt, kann der Beutel, beispielsweise in seinem verpackten Zustand gemäß der Darstellung nach der Fig. 5, auch ausschließlich über die Perforationslinie 38 wieder geöffnet werden, so dass sich analog zu der Beutelöffnung 28 eine vergleichbare, aber nicht-wiederschließbare Beutelöffnung unterhalb derselben ergibt.As shown in the Figures 3 and 6 the upper perforation line 38 also extends over the rear film surface 14, the bag, for example in its packaged state as shown in FIG Fig. 5 , are opened again exclusively via the perforation line 38, so that, analogously to the bag opening 28, a comparable, but non-reclosable bag opening results below the same.

Auch kann man durch Trennen der Perforationslinie 38 auf der Rückseite der Folienfläche 14 gemäß der Darstellung nach der Fig. 6 die Teile 16, 30 mit der geschlossenen Beutelöffnung 28 entfernen, so dass man ein Tablett gemäß der Darstellung nach der Fig. 7 erhält. Man kann aber auch die Perforationslinie 38 auf der Rückseite des Beutels, also entlang der hinteren Folienfläche 14 entfallen lassen, so dass die Teile 16, 30 gemäß der Darstellung nach der Fig. 6 auch rückwärtig verbleiben. Anstelle von H-förmig verlaufenden Perforationslinien 34, 36, 38 können diese auch in Form eines x-förmigen Kreuzes (nicht dargestellt) auf der vorderen Folienfläche 12 verlaufen, wobei dann nur zwei Perforationslinien benötigt werden, die mit ihren Enden jeweils an gegenüberliegenden Längsrändern 24 des Beutels ausmünden.Also, by separating the perforation line 38 on the back of the film surface 14 as shown in FIG Fig. 6 Remove the parts 16, 30 with the closed bag opening 28 so that you can see a tray as shown in the Fig. 7 receives. But it is also the perforation line 38 on the back of the bag, so omitted along the rear film surface 14, so that the parts 16, 30 as shown in the Fig. 6 also remain backward. Instead of H-shaped extending perforation lines 34, 36, 38, these may also (not shown) in the form of an X-shaped cross on the front film surface 12, in which case only two perforation lines are required, which at their ends respectively at opposite longitudinal edges 24th of the bag.

Alternativ kann auch vorgesehen sein, zwischen der Perforationslinie 38, die diesmal nur auf der Vorderseite des Snack-Beutels verläuft, und der darüberliegend angeordneten Klebstoffbahn 30 eine weitere Perforationslinie (nicht dargestellt) sowohl auf der Vorderseite als auch auf der Rückseite des Beutels durchgehend verlaufen zu lassen, was vorzugsweise einen in Längsrichtung gesehen etwas längeren Beutel voraussetzt, so dass neben der Beutelöffnung 28 oberhalb der Klebstoffbahn 30 eine unterhalb derselben liegende vergleichbare Beutelöffnung geschaffen ist, sobald die durchgehend umlaufende Perforationslinie, vorzugsweise beginnend an einem der beiden Längsränder 24 des Beutels, von Hand durchtrennt wird.Alternatively, it can also be provided to extend continuously between the perforation line 38, which this time runs only on the front side of the snack bag, and the adhesive web 30 arranged above it, a further perforation line (not shown) both on the front side and on the back side of the bag leave, which preferably requires a slightly longer bag seen in the longitudinal direction, so that in addition to the bag opening 28 above the adhesive sheet 30, a similar bag opening below it is created as soon as the continuous circumferential perforation line, preferably beginning at one of the two longitudinal edges 24 of the bag, is severed by hand.

Wie bereits erwähnt, können die Folienflächen 12, 14 aus einem dünnen Kunststoffmaterial gebildet sein, das durchsichtig ist und dem Benutzer eine unbehinderte Sicht auf den Behälterinhalt bietet. Bei dünn ausgebildetem Folienmaterial, beispielsweise mit einer Dicke im Bereich von 30µm, sind die Beutel kostengünstig mit geringem Materialaufwand herstellbar, wobei für den Benutzer eine geringe Menge an Abfall zu entsorgen ist, der zudem umweltfreundlich kompostierbar sein kann. Bei der Herstellung der Beutel ist das Format auf einfache Weise an die Art des vorgesehenen Füllguts anpassbar. Bei dem gezeigten Ausführungsbeispiel sind in beiden Folienflächen 12 und 14 jeweils sechs Belüftungslöcher 48 ausgebildet, die im Bereich des Beutel-Aufnahmeraums 40 benachbart zu den Längsrändern 24 in gleichen Abständen voneinander angeordnet sind und im Durchmesser so bemessen sind, dass der im Beutel befindliche Snack "atmen" kann, um länger frisch zu bleiben, dass jedoch der Beutel im Wesentlichen fett- und feuchtigkeitsundurchlässig und "tropfsicher" verbleibt. Wenn gewünscht, kann die Außenseite der Folienflächen 12, 14 mit einem dekorativen und/oder informativen Aufdruck versehen sein.As already mentioned, the foil surfaces 12, 14 may be formed of a thin plastic material that is transparent and provides the user with an unobstructed view of the container contents. In thin trained sheet material, for example, with a thickness in the range of 30 μ m, the bags are inexpensive to produce with low material costs, which is to dispose of the user a small amount of waste, which can also be environmentally friendly compostable. In the manufacture of the bag, the format is easily adaptable to the type of intended filling. In the embodiment shown, six ventilation holes 48 are formed in each of the two film surfaces 12 and 14, which are arranged in the region of the bag receiving space 40 adjacent to the longitudinal edges 24 at equal distances from each other and are dimensioned in diameter so that the snack in the bag " to "stay fresh longer," however, the pouch remains substantially impermeable to grease, moisture, and "drip-proof." If desired, the outside of the film surfaces 12, 14 may be provided with a decorative and / or informative imprint.
