Definitions
- the invention relates to a bag with a jacket wall which is closed from a flat material to a tubular shape by means of at least one longitudinal seam and having a plastic wall and at least one paper wall, and having at least one bottom which is folded at one end of the jacket wall, wherein the plastic wall at least partially double-layered and the two layers each have mutually offset ventilation perforations.
- bags are known in numerous embodiments. You can have such a stable jacket wall that they can be filled with a product with high weight.
- bags are common, which are filled with a pourable filling material with a mass of, for example, 5 to 50 kg to transport the contents of the manufacturer to the user.
- the jacket wall of such bags is formed with stable papers, especially with kraft paper. It is readily possible to form bags with a filling weight of the type mentioned with a single-layer or multi-layer jacket wall made of kraft paper in sufficient stability. However, if the contents are sensitive to moisture, it makes sense to form the jacket wall with at least one closed plastic wall, which is an effective barrier against moisture penetration. In such bags, however, arises - especially if they are designed as valve sacks and are filled via a filler neck of a filling machine - that with the Filling material inside the bag is trapped air, which leads to a bloated bag shape and prevents compacting of the contents inside the bag. Numerous attempts have therefore been made to allow venting of such a bag during filling and after filling.
- EP 1 813 545 B1 It is also known to form a bag with multiple layers of paper and provide a plastic liner.
- the plastic intermediate layer is not hermetically sealed, since the formation of the tubular jacket wall is effected by a longitudinal adhesive seam of the outer paper layer. This longitudinal adhesive seam is formed but interrupted, so that an air outlet is guaranteed for venting of the bag.
- a disadvantage of this solution in turn, that the conclusion against exposure to moisture is not complete, so that in particular a long-term exposure to moisture can have adverse effects on the contents.
- a bag of the type mentioned is through US 2005/0281494 A1 known.
- An inner layer of plastic material has vents, which are covered by a plastic strip.
- the plastic strip is also provided with ventilation openings, which are arranged offset to the ventilation openings of the inner layer.
- the plastic strip is fastened to the inner layer so that a sealed channel is formed, through which air exiting through the ventilation openings of the inner layer can flow to the ventilation openings of the plastic strip and thus can escape from the bag.
- the inner plastic layer may be covered with an outer paper layer of the bag.
- the plastic strip is on the plastic inner layer of the bag so applied that it forms the channel. Accordingly, there is a communication path between the outer space of the bag and the interior through which moisture can enter the interior and damage the contents.
- the present invention is therefore based on the problem to bring about a safe moisture removal in a bag of the type mentioned above while allowing venting during and after filling.
- the present invention is based on the fact that two plastic layers abut each other so that they are closed due to the staggered vent perforation at atmospheric pressure, so that at rest, an air or gas exchange between bag interior and bag exterior is not possible because the plastic layer hermetically encloses the interior. Due to an overpressure, in particular in the interior of the bag, the two plastic layers can separate from each other so that air can escape from the bag via the path of the venting perforations of the lower layer, the space between the two plastic layers and finally the venting perforation of the upper layer.
- a possibly inflated when filling sack can thus be vented by pressing against the bag wall, which leads to an overpressure in the bag interior, so that a compacting of the contents during filling, but also a subsequent compacting of the contents is possible.
- the air volume released from the product can be transferred via the two adjacent plastic layers are removed by the plastic layers are brought by the pressure to lift each other.
- Adjacent plastic layers regularly lead to an airtight seal. This effect can be further enhanced by selecting as the material of the plastic layers those materials which bring about a certain surface adhesion. Examples of these are films of low-density polyethylene, of polyvinyl alcohol or the like. Other plastic film materials allow the desired adhesion forces at least after a conventional surface treatment.
- the perforations extend in strips over a length of the bag running perpendicular to the bottom. In this way, venting is possible over the entire length of the bag.
- the perforations of the two layers in the width direction are arranged side by side, in particular when the perforations strip-shaped in the longitudinal direction - that is perpendicular to the width direction - extend.
- the perforation holes are preferably small and numerous and, for example, have a diameter between 0.2 and 5 mm, preferably between 0.5 and 2 mm, as circular perforation holes.
- a diameter between 0.2 and 5 mm, preferably between 0.5 and 2 mm, as circular perforation holes.
- other forms of perforation holes are possible, such as rectangular or polygonal holes, oval holes o. The like. Of importance is not the shape of the holes, but whose free flow cross-section
- the plastic wall has an applied plastic strip as a second layer.
- the plastic wall is self-contained and hermetically sealed, but provided with introduced in a suitable form perforation holes. These perforation holes are closed by the applied plastic strip, but in turn has perforation holes, which are not aligned with the perforation holes of the plastic wall, but arranged offset.
- the second layer may be glued or welded onto the plastic wall at the edges of the plastic strip. Since the plastic layers abutting offer an airtight seal, but it is sufficient to keep them otherwise pressed against each other at the edges of the plastic strip, for example by a seam, by riveting o. ⁇ .
- the two plastic layers can stand out from each other due to their connection by an overpressure to make a vent path free. This is achieved, for example, by the fact that when the two plastic layers are joined to one another, a stretching bias of at least one of the plastic layers is avoided so that they can be lifted from the other plastic layer due to their flexibility or elasticity.
- the formation of the second layer as a separate part can be avoided in that the two layers are formed overlapping ends of the plastic wall, which are fixed to each other on both sides of the perforations.
- the plastic wall With a given size, it is therefore possible to produce the plastic wall with a corresponding peripheral oversize and to provide in a suitable form with the perforation holes, so that they come to lie next to each other, for example, and in any case are not aligned.
- the plastic wall is not an outer wall of the bag, but is covered by a paper wall to the outside.
- the plastic wall can then be an inner wall or an intermediate wall of the jacket wall.
- the possibly more sensitive to external influences plastic assembly for venting is covered by a protective paper layer, wherein the paper layer may preferably have a vent slot. Since the paper layer is permeable to gas, the vent slot can be dispensed with if no rapid venting is required.
- FIG. 1 schematically shows a plastic wall 1, which has a perforation 2 extending over a longitudinal direction L of a bag.
- the perforation consists in the illustrated embodiment of three juxtaposed perforation holes, which are arranged one behind the other in the longitudinal direction L.
- a plastic strip 7 is applied on the plastic wall 1, in which it is hermetically sealed at its longitudinal edges with adhesive or welds 4 with the plastic wall 1.
- the plastic strip 7 has a second perforation 3, which is formed in the same way as the perforation 2 of the plastic wall 1, but laterally offset.
- the perforation of the plastic wall 1 takes in a width direction B one half of the width of the plastic strip 7, while the perforation 3 of the plastic strip 7 is disposed on the other half of the plastic strip 7.
- FIG. 2 schematically illustrates a cross section through a jacket wall of a bag, which consists of the plastic wall closed to a hose 1 and a surrounding outside, closed to a hose paper 8.
- the paper wall 8 is gas-permeable due to the material, while the plastic wall 1 is gas-permeable.
- FIG. 2 illustrates that the tubular plastic wall 1 is formed of a flat film which is closed by a longitudinal welding or adhesive seam 6 to the hose.
- the outer paper wall 8 is also made of a flat material and closed by a longitudinal adhesive seam 5 to form a tube.
- the sealing of the bag takes place in the area of the at least one floor.
- bottoms are formed by folding, for example, a crossbase, a block or block bottom, folded bottoms (ends) of flat bags, etc.
- the bag has a bottom at both ends and can be filled via a valve opening, so is a valve bag.
- the plastic strip 7 is applied to the tubular plastic wall 1 inside.
- the function results in the same way, however, even if the plastic strip 7 outside, that is attached between the plastic wall 1 and paper 8 on the plastic wall 1.
- FIG. 3 illustrates in a perspective view of the structure of a bag formed from a tubular material.
- the plastic wall 1 is hermetically sealed by means of the adhesive or weld seam 6, ie impermeable to gas and moisture. It is provided on the opposite side of the seam 6 with the perforation 2, which extends on one half of the width of the plastic strip 7 in the longitudinal direction L and is covered by a non-perforated part of the plastic strip 7 to the interior of the jacket wall.
- the plastic strip 7 has on its other half the perforation. 3 on, which is covered radially outwardly by a non-perforated portion of the plastic wall 1.
- the jacket wall is completed by an outer paper 8, so that the plastic wall 1 is an inner wall or an intermediate wall.
- An intermediate wall is present when a further paper layer is formed tubular on the inside of the plastic wall 1.
- the arrangement of the perforations 2 and 3 shown as an example is not mandatory for the venting function according to the invention. It is only important that the holes of the perforations 2 and 3 are not aligned with each other and are reliably closed by the juxtaposition of the plastic layers 1 and 7 in the idle state. It is readily possible to arrange the perforation holes of the two perforations 2 and 3 in interlaced patterns, so as to realize small ventilation paths.
- the length of the selected ventilation paths depends on the material, the thickness and the adhesion of the plastic layers 1, 7 and must be selected so that the gas-tight closure is not opened by the two plastic layers 1, 7 even at low pressure effects.
- the plastic wall 1 can form the vent strip itself by the plastic wall 1 is dimensioned so that beyond the adhesive or weld 6, an overlapping strip is formed and the two perforations 2, 3 are introduced in this area.
- the strip itself must then also be hermetically connected to the plastic wall 1 at its free end in order to ensure the sealing function.
- the operation of this embodiment is identical to that of the FIGS. 1 to 3 described mode of action.

Description
Die Erfindung betrifft einen Sack mit einer Mantelwandung, die aus einem flachen Material zu einer Schlauchform mittels wenigstens einer Längsnaht geschlossen ist und eine Kunststoffwandung und wenigstens eine Papierwandung aufweist, und mit wenigstens einem Boden, der an einem Ende der Mantelwandung gefaltet ist, wobei die Kunststoffwandung wenigstens teilweise zweilagig ausgebildet ist und die beiden Lagen jeweils zueinander versetzte Lüftungsperforationen aufweisen.The invention relates to a bag with a jacket wall which is closed from a flat material to a tubular shape by means of at least one longitudinal seam and having a plastic wall and at least one paper wall, and having at least one bottom which is folded at one end of the jacket wall, wherein the plastic wall at least partially double-layered and the two layers each have mutually offset ventilation perforations.
Derartige Säcke sind in zahlreichen Ausführungsformen bekannt. Sie können eine derart stabile Mantelwandung aufweisen, dass sie mit einem Füllgut mit hohem Gewicht füllbar sind. So sind beispielsweise Säcke üblich, die mit einem schüttfähigen Füllgut mit einer Masse von beispielsweise 5 bis 50 kg gefüllt werden, um das Füllgut vom Hersteller zum Anwender zu transportieren.Such bags are known in numerous embodiments. You can have such a stable jacket wall that they can be filled with a product with high weight. For example, bags are common, which are filled with a pourable filling material with a mass of, for example, 5 to 50 kg to transport the contents of the manufacturer to the user.
Aus Kostengründen und aus Gründen der Umweltverträglichkeit wird die Mantelwandung derartiger Säcke mit stabilen Papieren gebildet, insbesondere mit Kraftpapier. Es ist ohne weiteres möglich, Säcke mit einem Füllgewicht der genannten Art mit einer einlagigen oder mehrlagigen Mantelwandung aus Kraftpapier in ausreichender Stabilität auszubilden. Wenn das Füllgut allerdings gegen Feuchteeinwirkungen empfindlich ist, ist es sinnvoll, die Mantelwandung mit wenigstens einer geschlossenen Kunststoffwandung auszubilden, die eine wirksame Barriere gegen eindringende Feuchte darstellt. Bei derartigen Säcken ergibt sich allerdings - insbesondere wenn sie als Ventilsäcke ausgebildet sind und über einen Füllstutzen einer Füllmaschine befüllt werden -, dass mit dem Füllgut im Sackinneren Luft eingeschlossen wird, die zu einer aufgeblähten Sackform führt und ein Kompaktieren des Füllgutes im Sackinnern verhindert. Es sind daher zahlreiche Versuche unternommen worden, eine Entlüftung eines derartigen Sacks während des Befüllens und nach dem Befüllen zu ermöglichen.For cost reasons and for reasons of environmental compatibility, the jacket wall of such bags is formed with stable papers, especially with kraft paper. It is readily possible to form bags with a filling weight of the type mentioned with a single-layer or multi-layer jacket wall made of kraft paper in sufficient stability. However, if the contents are sensitive to moisture, it makes sense to form the jacket wall with at least one closed plastic wall, which is an effective barrier against moisture penetration. In such bags, however, arises - especially if they are designed as valve sacks and are filled via a filler neck of a filling machine - that with the Filling material inside the bag is trapped air, which leads to a bloated bag shape and prevents compacting of the contents inside the bag. Numerous attempts have therefore been made to allow venting of such a bag during filling and after filling.

Ein Sack der eingangs erwähnten Art ist durch
Der vorliegenden Erfindung liegt daher die Problemstellung zugrunde, bei einem Sack der eingangs erwähnten Art einen sicheren Feuchteabschluss herbeizuführen und gleichzeitig eine Entlüftung während und nach dem Befüllen zu ermöglichen.The present invention is therefore based on the problem to bring about a safe moisture removal in a bag of the type mentioned above while allowing venting during and after filling.
Dieses Problem wird gemäß der vorliegenden Erfindung bei einem Sack der eingangs erwähnten Art dadurch gelöst, dass die Lagen mit einer flächigen Adhäsion aneinander anliegen, sodass die Kunststoffwandung bei Normaldruck den Sackinnenraum hermetisch umschließt und dass die Lagen so zueinander fixiert sind, dass sie im Bereich der Perforationen aufgrund eines Überdrucks voneinander abheben.This problem is solved according to the present invention in a bag of the type mentioned in that the layers abut each other with a two-dimensional adhesion, so that the plastic wall hermetically encloses the bag interior at atmospheric pressure and that the layers are fixed to each other so that they are in the Separate perforations due to overpressure.
Die vorliegende Erfindung beruht darauf, dass zwei Kunststofflagen so aneinander anliegen, dass sie aufgrund der zueinander versetzten Entlüftungsperforation bei Normaldruck verschlossen sind, sodass im Ruhezustand ein Luft- oder Gasaustausch zwischen Sackinnenraum und Sackaußenraum nicht möglich ist, weil die Kunststofflage den Innenraum hermetisch umschließt. Aufgrund eines Überdrucks, insbesondere im Sackinnenraum, können sich die beiden Kunststofflagen voneinander trennen, sodass Luft über den Weg der Entlüftungsperforationen der unteren Lage, den Zwischenraum zwischen den beiden Kunststofflagen und schließlich die Entlüftungsperforation der oberen Lage aus dem Sack entweichen kann. Ein beim Füllen ggf. aufgeblähter Sack kann somit durch Drücken gegen die Sackwandung, das zu einem Überdruck im Sackinnenraum führt, entlüftet werden, sodass ein Kompaktieren des Füllguts beim Befüllen, aber auch ein nachträgliches Kompaktieren des Füllguts möglich ist. Das dabei aus dem Füllgut freigesetzte Luftvolumen kann über die beiden aneinanderliegenden Kunststofflagen entfernt werden, indem die Kunststofflagen durch den Überdruck zum Abheben voneinander gebracht werden.The present invention is based on the fact that two plastic layers abut each other so that they are closed due to the staggered vent perforation at atmospheric pressure, so that at rest, an air or gas exchange between bag interior and bag exterior is not possible because the plastic layer hermetically encloses the interior. Due to an overpressure, in particular in the interior of the bag, the two plastic layers can separate from each other so that air can escape from the bag via the path of the venting perforations of the lower layer, the space between the two plastic layers and finally the venting perforation of the upper layer. A possibly inflated when filling sack can thus be vented by pressing against the bag wall, which leads to an overpressure in the bag interior, so that a compacting of the contents during filling, but also a subsequent compacting of the contents is possible. The air volume released from the product can be transferred via the two adjacent plastic layers are removed by the plastic layers are brought by the pressure to lift each other.
Aneinander anliegende Kunststofflagen führen regelmäßig zu einem luftdichten Abschluss. Dieser Effekt kann noch dadurch verstärkt werden, dass als Material der Kunststofflagen solche Materialien ausgewählt werden, die eine gewisse Oberflächenhaftung mit sich bringen. Beispiele hierfür sind Folien aus Polyethylen niedriger Dichte, aus Polyvinylalkohol o. ä. Andere Kunststoff-Folienmaterialien ermöglichen die gewünschten Adhäsionskräfte zumindest nach einer üblichen Oberflächenbehandlung.Adjacent plastic layers regularly lead to an airtight seal. This effect can be further enhanced by selecting as the material of the plastic layers those materials which bring about a certain surface adhesion. Examples of these are films of low-density polyethylene, of polyvinyl alcohol or the like. Other plastic film materials allow the desired adhesion forces at least after a conventional surface treatment.
Um eine Entlüftung des gesamten Sackinnenraums zu erleichtern, ist es bevorzugt, dass sich die Perforationen streifenförmig über eine sich senkrecht zum Boden verlaufende Länge des Sacks erstrecken. Auf diese Weise ist über die gesamte Länge des Sacks eine Entlüftung möglich.In order to facilitate a venting of the entire bag interior, it is preferred that the perforations extend in strips over a length of the bag running perpendicular to the bottom. In this way, venting is possible over the entire length of the bag.
Selbstverständlich ist es weiterhin möglich, eine derartige Entlüftungsanordnung aus übereinanderliegenden Kunststofflagen nicht nur einmal, sondern mehrfach, beispielsweise zweimal, über den Umfang des Sacks auszubilden.Of course, it is still possible to form such a venting arrangement of superimposed plastic layers not only once, but several times, for example twice, over the circumference of the bag.
In einer bevorzugten und einfach herzustellenden Ausführungsform der Erfindung sind die Perforationen der beiden Lagen in Breitenrichtung nebeneinanderliegend angeordnet, insbesondere wenn sich die Perforationen streifenförmig in Längsrichtung - also senkrecht zu der Breitenrichtung - erstrecken.In a preferred and easy to manufacture embodiment of the invention, the perforations of the two layers in the width direction are arranged side by side, in particular when the perforations strip-shaped in the longitudinal direction - that is perpendicular to the width direction - extend.
Die Perforationslöcher sind vorzugsweise klein und zahlreich ausgebildet und weisen beispielsweise als kreisrunde Perforationslöcher einen Durchmesser zwischen 0,2 und 5 mm, vorzugsweise zwischen 0,5 und 2 mm, auf. Selbstverständlich sind auch andere Formen der Perforationslöcher möglich, beispielsweise rechteckige oder mehreckige Löcher, ovale Löcher o. dgl. Von Bedeutung ist dabei nicht die Form der Löcher, sondern derer freier StrömungsquerschnittThe perforation holes are preferably small and numerous and, for example, have a diameter between 0.2 and 5 mm, preferably between 0.5 and 2 mm, as circular perforation holes. Of course, other forms of perforation holes are possible, such as rectangular or polygonal holes, oval holes o. The like. Of importance is not the shape of the holes, but whose free flow cross-section
In einer einfachen Ausführungsform der Erfindung weist die Kunststoffwandung einen aufgebrachten Kunststoffstreifen als zweite Lage auf. Die Kunststoffwandung ist dabei in sich geschlossen und hermetisch abgedichtet, jedoch mit in geeigneter Form eingebrachten Perforationslöchern versehen. Diese Perforationslöcher werden durch den aufgebrachten Kunststoffstreifen verschlossen, der aber seinerseits Perforationslöcher aufweist, die jedoch nicht mit den Perforationslöchern der Kunststoffwandung fluchten, sondern versetzt angeordnet sind. Die zweite Lage kann auf die Kunststoffwandung an den Rändern des Kunststoffstreifens aufgeklebt oder aufgeschweißt sein. Da die Kunststofflagen aneinanderliegend eine luftdichte Abdichtung bieten, reicht es allerdings aus, sie auch anderweitig an den Rändern des Kunststoffstreifens gegeneinander gedrückt zu halten, beispielsweise durch eine Naht, durch Nieten o. ä.In a simple embodiment of the invention, the plastic wall has an applied plastic strip as a second layer. The plastic wall is self-contained and hermetically sealed, but provided with introduced in a suitable form perforation holes. These perforation holes are closed by the applied plastic strip, but in turn has perforation holes, which are not aligned with the perforation holes of the plastic wall, but arranged offset. The second layer may be glued or welded onto the plastic wall at the edges of the plastic strip. Since the plastic layers abutting offer an airtight seal, but it is sufficient to keep them otherwise pressed against each other at the edges of the plastic strip, for example by a seam, by riveting o. Ä.
Wesentlich ist für die Erfindung, dass die beiden Kunststofflagen aufgrund ihrer Verbindung miteinander durch einen Überdruck von einander abheben können, um einen Entlüftungsweg frei zu machen. Dies wird beispielsweise dadurch erreicht, dass bei der Verbindung der beiden Kunststofflagen miteinander eine dehnende Vorspannung zumindest einer der Kunststofflagen vermieden wird, damit sich diese von der anderen Kunststofflage aufgrund ihrer Flexibilität oder Elastizität abheben kann.It is essential for the invention that the two plastic layers can stand out from each other due to their connection by an overpressure to make a vent path free. This is achieved, for example, by the fact that when the two plastic layers are joined to one another, a stretching bias of at least one of the plastic layers is avoided so that they can be lifted from the other plastic layer due to their flexibility or elasticity.
In einer Variante der vorliegenden Erfindung kann die Ausbildung der zweiten Lage als separates Teil dadurch vermieden werden, dass die beiden Lagen durcheinander überlappende Enden der Kunststoffwandung gebildet sind, die beiderseits der Perforationen zueinander fixiert sind. Für eine vorgegebene Größe ist es daher möglich, die Kunststoffwandung mit einer entsprechenden Umfangs-Übergröße zu produzieren und in geeigneter Form mit den Perforationslöchern zu versehen, sodass sie beispielweise nebeneinander zu liegen kommen und jedenfalls nicht miteinander fluchten.In a variant of the present invention, the formation of the second layer as a separate part can be avoided in that the two layers are formed overlapping ends of the plastic wall, which are fixed to each other on both sides of the perforations. For a given size, it is therefore possible to produce the plastic wall with a corresponding peripheral oversize and to provide in a suitable form with the perforation holes, so that they come to lie next to each other, for example, and in any case are not aligned.
Für die vorliegende Erfindung ist es bevorzugt, dass die Kunststoffwandung nicht eine Außenwandung des Sacks darstellt, sondern durch eine Papierwandung nach außen abgedeckt ist. Die Kunststoffwandung kann dann eine Innenwandung oder eine Zwischenwandung der Mantelwandung sein. Auf diese Weise wird die gegen äußere Einwirkungen möglicherweise empfindlichere Kunststoffanordnung zur Entlüftung durch eine schützende Papierlage abgedeckt, wobei die Papierlage vorzugsweise einen Entlüftungsschlitz aufweisen kann. Da die Papierlage gasdurchlässig ist, kann auf den Entlüftungsschlitz verzichtet werden, wenn keine schnelle Entlüftung benötigt wird.For the present invention it is preferred that the plastic wall is not an outer wall of the bag, but is covered by a paper wall to the outside. The plastic wall can then be an inner wall or an intermediate wall of the jacket wall. In this way, the possibly more sensitive to external influences plastic assembly for venting is covered by a protective paper layer, wherein the paper layer may preferably have a vent slot. Since the paper layer is permeable to gas, the vent slot can be dispensed with if no rapid venting is required.

Es muss hier nicht weiter erläutert werden, wie die Abdichtung des Sacks im Bereich des wenigstens einen Bodens erfolgt. Aus der schlauchförmigen Mantelwandung werden in bekannter Technik Böden durch Faltung gebildet, beispielsweise ein Kreuzboden, ein Block- oder Klotzboden, gefaltete Böden (Enden) von Flachbeuteln usw.. Für die vorliegende Erfindung ist es bevorzugt, dass der Sack an beiden Enden einen Boden aufweist und über eine Ventilöffnung befüllbar ist, also ein Ventilsack ist.It need not be further explained here how the sealing of the bag takes place in the area of the at least one floor. From the tubular jacket wall in a known technique bottoms are formed by folding, for example, a crossbase, a block or block bottom, folded bottoms (ends) of flat bags, etc. For the present invention, it is preferred that the bag has a bottom at both ends and can be filled via a valve opening, so is a valve bag.

Wie
Es ist ohne weiteres ersichtlich, dass die als Beispiel dargestellte Anordnung der Perforationen 2 und 3 nicht zwingend für die erfindungsgemäße Entlüftungsfunktion ist. Es kommt lediglich darauf an, dass die Löcher der Perforationen 2 und 3 nicht miteinander fluchten und durch das Aneinanderliegen der Kunststofflagen 1 und 7 im Ruhezustand zuverlässig verschlossen sind.
