Abstract

The flexible plastics packaging bag has a single wall enclosing a space (14) for a substance which may give off gas. The gas pressure relief system consists of a double-wall zone with holes (12) for pressure relief in the inner wall (5). Molded projections may act as spacers for the outer wall (6) defining a gas escape zone (4). The edges (2,3) of the outer wall are held in place by welded or glued seams (7,8). A section of welded seam contains a separating material (11) and may give way to release the gas if the pressure builds up.

Description

Die vorliegende Erfindung betrifft flexible Verpackungsbehältnisse aus Kunststoff.The present invention relates to flexible plastic packaging containers.

Kunststoffverpackungen zeichnen sich dadurch aus, dass sie leicht, stabil, verhältnismäßig dicht, insbesondere wasser- und luftdicht, und dabei kostengünstig sind. Sie finden daher umfangreichen Einsatz bei der Verpackung von rieselfähigen Feststoffen in sehr vielen Bereichen, wie z.B. bei in der chemischen Industrie (Granulate etc.), im Gärtnereibereich (Blumenerde, Dünger) und im Lebensmittelbereich.Plastic packaging is characterized by being lightweight, stable, relatively tight, in particular water and airtight, while cost are. You will therefore find extensive use in the packaging of free-flowing solids in very many areas, such as at in the chemical Industry (granules, etc.), in the garden (potting soil, fertilizer) and in the garden The food industry.

Aus Kostengründen sind sogenannte FFS-Schläuche bevorzugt. Bei diesen wird das Verpackungsbehältnis aus einer Endlos-Folienbahn, meist direkt vor der Befüllung, erstellt. Entweder wird die Endlos-Folienbahn als Schlauch hergestellt, oder es erfolgt durch Rundlegen und Verschweißen oder Verkleben in Längsrichtung zunächst die Ausbildung eines Schlauches aus einer Flachfolie. Der Schlauch wird der Abfüllanlage zugeführt, wo eine erste Schweiß- oder Klebenaht in Querrichtung den Boden bildet und nach Einfüllen des Füllgutes das Behältnis durch eine zweite Schweiß- oder Klebenaht in Querrichtung oben verschlossen wird.For cost reasons, so-called FFS hoses are preferred. With these will the packaging container from an endless film web, usually directly in front of the Filling, created. Either the endless film web is produced as a hose, or it is done by rounding and welding or gluing in the longitudinal direction First, the formation of a tube from a flat film. Of the Hose is fed to the bottling plant, where a first welding or gluing seam in the transverse direction forms the bottom and after filling the contents of the container closed at the top by a second welding or gluing seam in the transverse direction becomes.

Bei der Verpackung von Baustoffen, welche häufig hygroskopisch sind, kommt es besonders auf den Schutz des Inhalts vor Feuchtigkeit an. Andererseits werden solche Güter bisher noch vielfach in Papierbehältnissen abgefüllt, da sich gerade bei Zement und ähnlichen Stoffen während und nach der Abfüllung ein Überdruck in der Verpackung bildet, der durch Papier entweichen kann, jedoch bei den luftdichten Kunststoffverpackungen nach dem Verschließen verbleibt.In the packaging of building materials, which are often hygroscopic, it comes especially on the protection of the contents from moisture. On the other hand such goods still often bottled in paper containers, since just Cement and similar substances during and after filling overpressure forms in the package, which can escape through paper, but in the Airtight plastic packaging remains after closing.

Zur Vermeidung dieser Probleme ist es bei sogenannten Klotzbodensäcken bekannt, in dem Boden ein Ventil vorzusehen, durch das der Überdruck bei der Abfüllung entweicht. Klotzbodensäcke und besonders solche mit aufwändigen Ventilkonstruktionen sind jedoch aus Kostengründen für vergleichsweise preiswerte Füllgüter wie Baustoffe nicht erwünscht.To avoid these problems, it is in so-called block bottom bags known to provide a valve in the bottom, through which the overpressure in the Bottling escapes. Block bottom sacks and especially those with elaborate ones However, valve designs are for cost reasons for comparative inexpensive products such as building materials not desired.

Die EP 444 261 beschreibt flexible Verpackungsbehältnisse in Form eines Sackes oder Beutels, bei denen eine Entlüftung durch Perforationen in einem Bereich des Behältnisses erfolgt, in welchem dieses zweilagig ausgebildet ist. Hierzu sind in der inneren und der äußeren Wandung jeweils Perforationen vorgesehen, wobei die Perforationen in der äußeren Wandung eine geringere Querschnittsfläche haben sollen, als die in der inneren Wandung. Die Entlüftung erfolgt dann dadurch, dass sich zwischen der inneren und der äußeren Wandung ein Überdruck aufbaut, der ein kontrolliertes Ausströmen ermöglichen soll. Der Schrift lässt sich entnehmen, dass bei sehr feinen Füllgütern ein Filter zwischen innerer und äußerer Wandung benötigt wird, um ein Austreten des Füllgutes zu verhindern. Außerdem bilden diese nach dem Entweichen des Überdruckes unmittelbar übereinander liegenden Perforationen eine Eintrittsöffnung für Luft, Wasser und andere Verunreinigungen.EP 444 261 describes flexible packaging containers in the form of a bag or bag, where a vent through perforations in a range of Container takes place, in which this is formed in two layers. These are in the inner and the outer wall perforations provided, wherein the perforations in the outer wall have a smaller cross-sectional area should have, than those in the inner wall. The venting then takes place in that there is an overpressure between the inner and the outer wall builds up, which should allow a controlled outflow. The writing leaves It can be seen that for very fine products a filter between inner and outer wall is required to prevent leakage of the filling material. In addition, these form immediately after the escape of the overpressure superimposed perforations an inlet for air, water and other impurities.

Es besteht daherweiterhin ein Bedarf an einem preiswerten und gleichzeitig sicher vor Verunreinigung und/oder Feuchtigkeit schützenden Verpackungsbehältnis für solche Füllgüter, bei denen während und/oder nach dem Einfüllen ein Überdruck abzuleiten ist.There is therefore still a need for a cheap and at the same time safe from contamination and / or moisture-proof packaging container for such contents, in which during and / or after filling a Derive overpressure.

Diese Aufgabe wird gelöst durch ein flexibles Verpackungsbehältnis aus Kunststoff, bei welchem mittels Schweiß- oder Klebenähten ein Bereich ausgebildet ist, der eine innere und eine äußere Wandung aufweist, wobei in der inneren Wandung Öffnungen vorgesehen sind, die einen Gasaustritt aus dem Inneren des Behältnisses in den Bereich zwischen der inneren und der äußeren Wandung ermöglichen, und die den Bereich einschließenden Schweiß- bzw. Klebenähte zumindest in einem Teilbereich einen Gasaustritt ermöglichen. This task is solved by a flexible packaging container Plastic, in which by means of welding or adhesive seams, an area is formed, which has an inner and an outer wall, wherein in the inner wall openings are provided, which emit a gas from the Inside the container in the area between the inner and the outer Wandungs enable, and enclosing the area welding or Adhesive seams allow at least in a partial area a gas outlet.

Überraschenderweise ist es möglich, die Schweiß- bzw. Klebenaht in Teilbereichen gasdurchlässig auszubilden, ohne die Stabilität der Verpackung zu beinträchtigen.Surprisingly, it is possible, the welding or adhesive seam in Partial gas-permeable forms without the stability of the packaging affect.

Als Verpackungsbehältins im Sinne der vorliegenden Erfindung kommen unter anderem FFS-Schläuche, Blocksäcke, offene Seitenfalten- und/oder Flachsäcke, Ventilkastensäcke (geklebt und geschweißt), Kreuzbodensäcke, Automaten(flach)folie usw. in Betracht, insbesondere FFS-Verpackungen.As Verpackungsbehältins in the context of the present invention come under other FFS hoses, block sacks, open gussets and / or flax sacks, Valve box sacks (glued and welded), crossfloor sacks, Vending machines (flat) film etc., in particular FFS packaging.

Besonders bevorzugt sind weiterhin solche Verpackungsbehältnisse, bei denen die Herstellung aus einer Flachfolie erfolgt, so dass bereits herstellungsbedingt zwischen den Außenkanten der Folienbahn in Längsrichtung ein Überlapp vorhanden ist, der als Bereich zwischen innerer und äußerer Wandung dienen kann. Bei diesen Verpackungsbehältnissen ist eine gesonderte Ausbildung dieses Bereichs somit nicht nötig.Furthermore, such packaging containers are particularly preferred in which the production is made from a flat film, so that already production reasons between the outer edges of the film web in the longitudinal direction of an overlap which serve as a region between inner and outer wall can. In these packaging containers is a separate training this Area not necessary.

Bei Verpackungsbehältnissen, bei denen, z.B. durch Blasextrusion, die Kunststofffolie direkt als Schlauch hergestellt wird, kann der Bereich zwischen innerer und äußerer Wandung dadurch ausgebildet werden, dass eine separate Folie mittels Schweiß- oder Klebeverbindung auf der das Verpackungsbehältnis bildenden Folie angebracht wird.For packaging containers where, e.g. through bubble extrusion, the plastic film directly as hose is made, the area between inner and outer wall are formed by a separate film means Welding or adhesive bond on the packaging container forming Foil is attached.

Vorzugsweise wird eine oder beide Schweiß- bzw. Klebenaht bzw. -nähte in Querrichtung gasdurchlässig ausgebildet. Es ist aber auch möglich, sofern vorhanden, die Schweiß- bzw. Klebenaht in Längsrichtung insgesamt oder in Teilbereichen gasdurchlässig auszubilden.Preferably, one or both weld or adhesive seam or seams in Transverse gas-permeable formed. But it is also possible, provided present, the weld or adhesive seam in the longitudinal direction in total or in Partial gas-permeable form.

Eine bevorzugte Möglichkeit zur Ausbildung der Gasdurchlässigkeit besteht darin, die Oberfläche der Folie an den zu verbindenden Stellen oder auch insgesamt durch Aufbringen eines Trennmediumsoder durch Corona-Behandlung so zu verändern, dass die Verbindung eine herabgesetzte Festigkeit aufweist. Der Auftrag bzw. die Behandlung kann dabei einseitig oder mehrseitig, vollflächig oder partiell erfolgen. Als Trennmedium eignen sich alle Medien, die ein Verschweißen oder Verkleben der Kunststofffolie verhindern, wie z.B. Öle, Fette, Faben, Lacke, pulverförmige Feststoffe, usw.A preferred way of forming the gas permeability is to the surface of the film at the points to be joined or even in total by applying a separation medium or by corona treatment so too change that the compound has a reduced strength. Of the Order or treatment may be one-sided or multi-sided, full-surface or partially done. Suitable media are all media that are welding or prevent the plastic film from sticking, e.g. Oils, greases, hides, varnishes, powdery solids, etc.

Die geschwächte Verbindungsnaht gewährleistet einen kontrollierten Gasaustritt zum Abbau eines während oder nach der Füllung auftretenden Überdrucks. Der Einsatz von Filtern oder ähnlichem, die im Stand der Technik zur Verhinderung eines Austritts von Füllgut erforderlich waren, ist nicht nötig, da die Öffnungen in der inneren Wandung von der dichten, äußeren Wandung abgedeckt sind. Auch ist durch die geschwächte Verbindungsnaht ein Austritt selbst von sehr feinen Partikeln nahezu unmöglich. Dies beruht darauf, dass zwischen den beiden nur teilweise fest verbundenen Folien Adhäsionskräfte wirken, die eine gewisse Haftung auch ohne feste Verbindung durch Schweißen bzw. Kleben bewirken. Nur wenn durch eine Druckdifferenz wie den beim oder nach der Abfüllung sich entwickelnden Überdruck die Adhäsionskräfte überwunden werden, öffnet sich die Verbindungsnaht und lässt den Überdruck entweichen.The weakened connection seam ensures a controlled gas outlet to reduce a pressure occurring during or after the filling. Of the Use of filters or the like for preventing in the prior art A discharge of contents were required is not necessary because the openings in the inner wall of the dense, outer wall are covered. Also is due to the weakened connection seam an outlet itself of very fine Particles almost impossible. This is because that between the two only Partially firmly bonded films act on adhesion forces that have a certain Adhesion even without firm connection by welding or gluing effect. Just if by a pressure difference like that during or after bottling itself developing overpressure, the adhesion forces are overcome, which opens Seam and allows the pressure to escape.

Im Gegensatz zum Stand der Technik sind demzufolge weder aufwändige Ventilkonstruktionen noch Perforationen der äußeren Wandung nötig.In contrast to the prior art are therefore neither expensive Valve constructions still perforations of the outer wall necessary.

Auch eine Vlieseinlage zur Rückhaltung von Verpackungsgut, das in den Bereich zwischen innerer und äußerer Wandung eindringen könnte, ist entbehrlich. Da die Öffnungen in der inneren Wandung von den geschwächten Verbindungsnähten beabstandet sind, vorzugsweise sind die Öffnungen nur in der Mitte des Behältnisses und die Quernähte sind geschwächt, ist ein Austritt von Verpackungsgut aufgrund des langen Weges nahezu ausgeschlossen. Gleiches gilt für evtl. von außen in den Bereich zwischen innerer und äußerer Wandung eindringende Verunreinigungen.Also a fleece insert for the retention of packaged goods, which in the range between inner and outer wall could penetrate, is unnecessary. Because the Openings in the inner wall of the weakened connecting seams are spaced apart, preferably, the openings are only in the middle of the Container and the transverse seams are weakened, is an exit from Packaged goods almost impossible due to the long journey. The same Applies to possibly from the outside in the area between the inner and outer wall penetrating impurities.

Die Öffnungen in der inneren Wandung sind vorzugsweise durch Nadelung gebildete Perforationen. Es ist aber auch möglich, Schlitze oder andere einen Gasdurchtritt ermöglichende Öffnungen vorzusehen. Bevorzugt werden die Öffnungen, insbesondere für sehr feine Füllgüter, so angeordnet, dass sich ein möglichst langer Weg von den Öffnungen zu dem (Teil-)Bereich der Verbindungsnaht ergibt, der den Gasaustritt ermöglicht.The openings in the inner wall are preferably by needling formed perforations. But it is also possible slots or other one Provide gas passage permitting openings. Preference is given to Openings, especially for very fine contents, arranged so that a the longest way possible from the openings to the (partial) area of the Connecting seam results, which allows the gas outlet.

Eine bevorzugte Ausführungsform weist daher Öffnungen auf, die in Längsrichtung mittig angeordnet sind, und der den Gasaustritt ermöglichende Teilbereich ist in einer oder beiden Quernähten ausgebildet.A preferred embodiment therefore has openings in the longitudinal direction are arranged centrally, and the gas outlet enabling Part area is formed in one or both transverse seams.

Zur weiteren Verbesserung des Abbaus eines Überdruckes vor allem bei gestapelten Verpackungsbehältnissen können zwischen der inneren und der äußeren Wandung Abstandshalter vorgesehen sein. Brauchbar sind beispielsweise Prägungen.To further improve the reduction of overpressure especially at Stacked packaging containers can be between the inner and the outer wall spacer may be provided. Are usable for example, imprints.

Diese Abstandshalter sorgen dafür, dass auch bei den in einem Stapel unten liegenden Behältnissen das austretende Gas in dem Bereich zwischen innerer und äußerer Wandung bis zu den geschwächten Teilen der Verbindungsnähte gelangt. Es wäre ohne Abstandshalter denkbar, dass innere und äußere Wandung durch den Druck der aufliegenden Behältnisse so stark aufeinander gedrückt werden, dass der Überdruck im Inneren des Behältnisses entweder nicht in den Bereich zwischen innerer und äußerer Wandung gelangt oder dort nicht bis zu den geschwächten (Teil-)Bereichen der Verbindungsnaht bzw. -nähte.These spacers ensure that even when in a stack below The leaking gas in the area between inner and outer outer wall reaches to the weakened parts of the connecting seams. It would be conceivable without spacers that inner and outer wall through the pressure of the resting containers are pressed together so strongly that the overpressure inside the container is either not in the range between inner and outer wall reaches or not there to the Weakened (partial) areas of the connection seam or seams.

Die Herstellung der erfindungsgemäßen Verpackungsbehältnisse erfolgt im wesentlichen ebenso wie diejenige der nicht mit einer Überdruckentlüftung versehenen Behältnisse. Es ist lediglich vor der Anbringung zumindest einer Verbindungsnaht der zusätzliche Schritt einer Oberflächenbehandlung nötig, durch die bei der späteren Herstellung der Verbindungsnaht eine Gasdurchlässigkeit derselben zumindest in Teilbereichen erreicht wird.The preparation of the packaging containers according to the invention takes place in essential as well as the one not with a positive pressure vent provided containers. It is only before attaching at least one Join seam the additional step of a surface treatment necessary, through in the later production of the seam, a gas permeability same is achieved at least in some areas.

Die vorliegende Erfindung soll am Beispiel einer FFS-Verpackung im folgenden anhand der beigefügten Figuren näher erläutert werden, ohne jedoch darauf beschränkt zu sein.The present invention is based on the example of an FFS packaging in the following will be explained in more detail with reference to the accompanying figures, but without it to be limited.

Figur 1 zeigt eine Seitenansicht einer FFS-Verpackung.FIG. 1 shows a side view of an FFS packaging.

Figur 2 zeigt einen Schnitt entlang der Linie A-A in Figur 1.FIG. 2 shows a section along the line A-A in FIG. 1.

In Figur 1 ist ein FFS-Schlauch 1 zu sehen, der aus einer Kunststofffolie hergestellt ist, indem diese in Längsrichtung so zusammengelegt wurde, dass zwischen den beiden Außenkanten der Folie 2 und 3 ein Bereich 4 mit einer inneren Wandung 5 und einer äußeren Wandung 6 (vgl. Figur 2) gebildet wird. Zwei Schweißnähte 7 und 8 in Längsrichtung fixieren die Außenkanten 2 und 3 der Folie mit der darunter bzw. darüber liegenden Folie, so dass ein Schlauch ausgebildet wird. Das Verpackungsbehältnis wird vor dem Befüllen mit einer den Boden bildenden Schweißnaht 9 und nach dem Befüllen mit einer Schweißnaht 10 versehen, welche die Verpackung verschließt.FIG. 1 shows an FFS hose 1, which consists of a plastic film is made by these longitudinally merged so that between the two outer edges of the film 2 and 3, a region 4 with a inner wall 5 and an outer wall 6 (see Figure 2) is formed. Two weld seams 7 and 8 in the longitudinal direction fix the outer edges 2 and 3 the film with the underlying or overlying film, so that a hose is trained. The packaging container is filled before filling with a Floor forming weld 9 and after filling with a weld 10th provided, which closes the packaging.

Die Außenkante 2 der Folie ist auf der später zum Inneren 14 des Behältnisses 1 gewandten Seite mit einem Trennlack 11 versehen, der dazu führt, dass die Schweißnaht 7 einen Gasaustritt ermöglicht. Weiterhin sind entlang der Außenkante 3 in Längsrichtung Perforationen 12 und Prägungen 13 angebracht. The outer edge 2 of the film is on the later to the interior 14 of the container. 1 side facing provided with a release varnish 11, which causes the Weld 7 allows a gas outlet. Furthermore, along the Outside edge 3 in the longitudinal direction perforations 12 and embossments 13 attached.

In Figur 2 ist zu erkennen, dass die Perforationen 12 nach der Verschweißung zu einem Schlauch in der inneren Wandung des Bereiches 4 zu liegen kommen. Dies trifft ebenfalls auf die Prägungen 13 zu, die jedoch in Figur 2 nicht dargestellt sind.In Figure 2 it can be seen that the perforations 12 after welding to a tube in the inner wall of the area 4 come to rest. This also applies to the embossments 13, which are not shown in Figure 2.

Sobald sich im Inneren 14 der Verpackung 1 ein Überdruck bildet, wird das Gas durch die Perforationen 12 in den Bereich 4 eintreten und wird von dort durch die gasdurchlässige Schweißnaht 7 nach außen abgeleitet. Ein eventuelles Eindringen von Füllgut in den Bereich 4 ist unschädlich, da dieses durch die Schweißnaht kaum austreten kann. Auch ein Eindringen von Verunreinigungen in den Innenraum 14 ist nicht zu befürchten, da nach dem Abbau des Überdrucks die innere und die äußere Folie dicht aufeinander liegen und durch Adhäsionskräfte in dieser Lage fixiert werden.As soon as an overpressure forms in the interior 14 of the packaging 1, the gas becomes through the perforations 12 in the area 4 and is from there through the gas permeable weld 7 derived to the outside. A possible Penetration of contents in the area 4 is harmless, since this by the Weld seam can hardly escape. Also, penetration of impurities in the interior 14 is not to be feared because after the reduction of the overpressure the Inner and outer film are close to each other and by adhesion forces in be fixed in this position.

Mit der erfindungsgemäßen Verpackung ist es somit möglich auch zementhaltige Baustoffe zu verpacken, welche hygroskopisch sind und nach dem Abfüllen zur Ausbildung eines Überdruckes neigen.With the packaging according to the invention it is thus possible also cementitious To pack building materials which are hygroscopic and to be filled after filling Training an overpressure tend.

Figur 3 zeigt eine FFS-Verpackung mit einer alternativen gasdurchlässigen Verbindungsnaht. Gleiche Teile sind mit gleichen Bezugsziffern gekennzeichnet.Figure 3 shows an FFS package with an alternative gas permeable Seam. Identical parts are marked with the same reference numbers.

In Figur 3 erkennt man einen FFS-Schlauch 1, bei dem anstelle des Trennlackes ein Corona-behandelter Bereich 11' vorgesehen ist. Die Querschweißnähte 9 und 10 ermöglichen dadurch an der Stelle, an der Bereich 11' liegt, einen Gasaustritt bei Überdruck. Die Öffnungen sind als Perforationen 12 nur in der Mitte des Sackes ausgebildet. Abstandshalter sind hier nicht vorgesehen. Diese Ausführungsform ist besonders für sehr feinteilige Füllgüter geeignet, da sich ein besonders langer Weg von den Öffnungen zu dem Bereich das Gasaustrittes ergibt. Hierdurch kann ein Austreten von Füllgut praktisch vollständig verhindert werden.FIG. 3 shows a FFS tube 1, in which instead of the release varnish a corona treated area 11 'is provided. The transverse welds 9 and 10 thereby allow at the location at the area 11 ', a gas outlet at overpressure. The openings are as perforations 12 only in the middle of the Sackes trained. Spacers are not provided here. These Embodiment is particularly suitable for very finely divided contents, since a particularly long way from the openings to the area of the gas outlet results. As a result, leakage of filling virtually completely prevented become.
