Die Verwendung dieses Materials verhindert das Einreißen des Deckblattes bei Verwendung des Tragegriffs. Außerdem weist das Material eine genügend hohe Tragfähigkeit auf, die ein Abreißen des Tragegriffs verhindert. Bevorzugt wird das Deckblatt aus mit Kunststoff verstärktem Papier hergestellt bzw. gebildet. Dabei handelt es sich um eine Kunststoffschicht, bevorzugt aus Polyethylen oder Polypropylen und/oder in Netzform, die in Papierschichten eingearbeitet ist. Bevorzugt liegt das Kunststoffnetz zwischen mindestens zwei Papierschichten (Lagen). Gegebenenfalls enthält das verstärkte Papier als weitere Schicht eine Kunststofffolie. Bevorzugt handelt es sich um sogenanntes Bändchengewebe.The cover sheet is formed or made of a tear and / or tensile material. Such a material is used in particular in the cover sheet with integrated carrying handle. The use of this material prevents tearing of the cover sheet when using the carrying handle. In addition, the material has a sufficiently high load capacity, which prevents tearing of the handle. Preferably, the cover sheet is made of plastic reinforced paper or formed. This is a plastic layer, preferably made of polyethylene or polypropylene and / or in net form, which is incorporated in paper layers. The plastic net preferably lies between at least two paper layers (layers). Optionally, the reinforced paper contains as a further layer a plastic film. It is preferably so-called ribbon fabric.

In einer Variante der vorliegenden Erfindung ist das Deckblatt aus mindestens zwei Schichten gebildet. Der erfindungsgemäße Kreuzbodensack weist mindestens ein Deckblatt aus, in welchem der Tragegriff integriert ist.In a variant of the present invention, the cover sheet is formed from at least two layers. The cross-bottom bag according to the invention has at least one cover sheet in which the carrying handle is integrated.

Das den Tragegriff enthaltende Deckblatt wird mit den darunter liegenden Seitenlaschen fest verbunden bevorzugt verklebt.The cover sheet containing the carrying handle is preferably adhesively bonded to the underlying side flaps.

In einer Variante ragt das Deckblatt in Längsrichtung über die gefalteten Seitenlaschen hinaus und wird in diesem Bereich auch mit dem Seiteneinschlag und gegebenenfalls mit dem Innenriegel verbunden. Auf einer Querseite des Deckblattes erfolgt im Bereich des Aufreißstreifens keine Verbindung mit dem Innenriegel, so dass ein leichtes Aufgreifen des Aufreißstreifens ermöglicht wird.In a variant, the cover sheet protrudes in the longitudinal direction beyond the folded side flaps and is in this area also with the side impact and optionally connected to the inner bar. On a transverse side of the cover sheet is in the region of the tear strip no connection with the inner bar, so that a slight picking up of the tear strip is made possible.

Zur Bildung des Tragegriffs sind in dem Deckblatt zwei Schnitte ausgestanzt, die die Seitenkanten des Tragegriffs bilden. Die ausgestanzten Schnitte bzw. Seitenkanten können gerade, aber auch konvex/konkav sein.To form the carrying handle two sections are punched in the cover sheet, which form the side edges of the handle. The punched cuts or side edges can be straight, but also convex / concave.

Bevorzugt wird als Kleber Stärke-Kleber oder Dispersions-Kleber verwendet.The cover sheet with integrated carrying handle is preferably connected by means of adhesive to the underlying elements of the cross-bottom bag. Preferably, the adhesive used is starch adhesive or dispersion adhesive.

Der erfindungsgemäße Kreuzbodensack weist mindestens im Standboden, gegenüber dem Oberteil bzw. Ventilboden, einen Innenriegel auf.The cross bottom bag according to the invention has at least in the ground floor, opposite the upper part or valve bottom, an inner latch.

Der Innenriegel ist ein im Wesentlichen rechteckiges Blatt oder Zettel, bevorzugt aus Papier, das im Sackinneren den Sackboden bildet und direkten Kontakt zum Füllgut hat. Der Innenriegel wird ringsum mit den Seitenlaschen und den Bodeneinschlägen verbunden. In einer Ausführung weist der Innenriegel einen Umschlag, also eine Faltung an einer Querseite, also im Bereich eines Bodeneinschlags zum Sackinneren hin, auf.The inner bar is a substantially rectangular sheet or piece of paper, preferably made of paper, which forms the bottom of the bag the bottom of the bag and has direct contact with the contents. The inner bar is connected all around with the side flaps and the ground covers. In one embodiment, the inner latch has an envelope, that is to say a fold on a transverse side, that is to say in the region of a bottom impact toward the interior of the bag.

Der Aufreißstreifen ist auf dem Innenriegel angebracht und mit diesem verbunden. Der Innenriegel wird so mit den o.g. Sackelementen verbunden, dass der Aufreißstreifen zum Sackinneren hinweist. Der Aufreißstreifen erstreckt sich bevorzugt über die gesamte Länge des Innenriegels längs des Standbodens. An einer Querseite des Innenriegels, also senkrecht zur Längsachse des Bodens, wird der Innenriegel an einem Ende des Aufreißstreifens nicht mit dem darunter liegenden Bodeneinschlag verbunden. Bevorzugt erfolgt dies an der Querseite mit der oben beschriebenen Faltung des Innenriegels zum Sackinneren hin. An diesem Ende ist der Aufreißstreifen leicht greifbar.The tear strip is mounted on the inner bar and connected thereto. The inner bar is connected to the above-mentioned bag elements so that the tear strip points to the interior of the bag. The tear strip preferably extends along the entire length of the inner bar along the stand. On a transverse side of the Inside bar, so perpendicular to the longitudinal axis of the soil, the inner bar is not connected at one end of the tear strip with the underlying ground impact. This is preferably done on the transverse side with the above-described folding of the inner bar towards the interior of the bag. At this end, the tear strip is easily accessible.

In einer Ausführung sind neben dem Aufreißstreifen Schnitte, Löcher oder andere Sollbruchstellen angebracht, die ein leichtes Aufreißen ermöglichen. In einer Variante sind diese Sollbruchstellen, insbesondere Schnitte, lediglich am Rande des Innenriegels zu finden. Die Faltung kann 0,1 - 5 cm, bevorzugt 0,5 - 3 cm, besonders bevorzugt 0,5 - 2,5 cm betragen. Die Sollbruchstellen erstrecken sich über den Bereich der Faltung, bevorzugt in einem kleineren Bereich von 0,1 - 2,5, besonders bevorzugt 0,1 - 2 cm, insbesondere 0,1 - 1 cm.In one embodiment, in addition to the tear strip cuts, holes or other predetermined breaking points are attached, which allow easy tearing. In one variant, these predetermined breaking points, in particular cuts, can only be found at the edge of the inner bar. The folding may be 0.1-5 cm, preferably 0.5-3 cm, more preferably 0.5-2.5 cm. The predetermined breaking points extend over the region of the folding, preferably in a smaller range of 0.1-2.5, particularly preferably 0.1-2 cm, in particular 0.1-1 cm.

Zum Verschließen des Sackbodens wird der Innenriegel zusammen mit den Seitenlaschen gefaltet. Der Innenriegel erstreckt sich in der Breite bis maximal zur Kante der Seitenlasche.To close the bottom of the bag, the inner bar is folded together with the side straps. The inner bar extends in width to a maximum of the edge of the side flap.

In einer Variante werden die Seitenlaschen zusammen mit dem Innenriegel so gefaltet, dass die Seitenkanten auf Stoß liegen. In einer weiteren Alternative werden die Seitenlaschen zusammen mit dem Innenriegel so gefaltet, dass die Seitenkanten in einem Abstand zueinander liegen, der mindestens der Breite des Aufreißstreifens entspricht bzw. gleich ist oder um 2%, 2,5%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15% 20% größer oder kleiner als die Breite des Aufreißstreifens ist.In one variant, the side flaps are folded together with the inner bar so that the side edges are in abutment. In a further alternative, the side flaps are folded together with the inner bar so that the side edges are at a distance which is at least equal to the width of the tear strip or equal to or 2%, 2.5%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15% 20% is greater or less than the width of the tear strip.

Die übereinander gefalteten Flächen des Innenriegels werden miteinander verbunden. Ebenso werden die darüber hinaus ragenden Flächen der Seitenlaschen mit dem Innenriegel fest verbunden.The superimposed folded surfaces of the inner bar are connected together. Likewise, the beyond projecting surfaces of the side flaps are firmly connected to the inner bar.

In einer Ausführung befindet sich der Aufreißstreifen in der Mitte des Innenriegels, wobei der Innenriegel symmetrisch zur Längsachse des Bodens angebracht ist, so dass sich der Aufreißstreifen in der Längsachse des Bodens befindet.In one embodiment, the tear strip is located in the center of the inner bar, with the inner bar being mounted symmetrically to the longitudinal axis of the floor so that the tear strip is in the longitudinal axis of the floor.

Die Seitenlaschen sind ebenfalls symmetrisch ausgebildet, so dass nach deren Faltung in einer Ausführung sich der freie Bereich durch den nicht überlappenden Seitenkanten der Seitenlaschen ebenfalls in der Längsachse des Bodens befindet.The side flaps are also formed symmetrically, so that after their folding in one embodiment, the free area is also in the longitudinal axis of the soil by the non-overlapping side edges of the side flaps.

In einer weiteren Ausführung sind jedoch auch asymmetrische Faltungen möglich, wobei der Aufreißfaden bevorzugt unterhalb eines nicht überlappenden Bereiches der Seitenlaschen vorzufinden ist, insbesondere parallel zur Längsachse des Bodens.In a further embodiment, however, asymmetrical folds are also possible, wherein the tear-open thread is preferably to be found below a non-overlapping region of the side flaps, in particular parallel to the longitudinal axis of the base.

Der Aufreißstreifen ist aus einem Material mit höherer Reiß- und/oder Zugfestigkeit als der Innenriegel gebildet. Dadurch ist sichergestellt, dass der Innenriegel vor dem Aufreißstreifen bei Anwendung von Zugkräften, wie sie bei Öffnen des Sacks eingesetzt werden, reißt. Bevorzugt ist der Aufreißstreifen aus Kunststoff, insbesondere Polypropylen.The tear strip is formed from a material with higher tear and / or tensile strength than the inner bar. This ensures that the inner bar before the tear strip under use of tensile forces, as they are used when opening the bag breaks. Preferably, the tear strip is made of plastic, in particular polypropylene.

Der Aufreißstreifen kann in Form eines flachen Streifens ausgebildet sein oder aber auch rund sein, zum Beispiel in Form einer Schnur oder eines Fadens.The tear strip may be formed in the form of a flat strip or else be round, for example in the form of a string or a thread.

Eine weitere Variante betrifft den erfindungsgemäßen Kreuzbodensack, bei welchem der Aufreißstreifen und der Tragegriff übereinander und mittig zum Deckblatt angeordnet sind.Another variant relates to the inventive cross-bottom bag, in which the tear strip and the carrying handle are arranged one above the other and centrally to the cover sheet.

In einer Ausführung weist der erfindungsgemäße Kreuzbodensack mindestens eine Entlüftungsvorrichtung auf.In one embodiment, the cross-bottom bag according to the invention has at least one ventilation device.

In einer weiteren Variante handelt es sich um einen Kreuzbodensack mit einem Tragegriff am Standboden und einer Entlüftungsvorrichtung im Oberteil bzw. im Ventilboden.In a further variant, it is a cross-bottom bag with a handle on the floor and a ventilation device in the upper part or in the valve bottom.

In einer weiteren Ausführung ist der Kreuzbodensack dadurch gekennzeichnet, dass die zum Sackäußeren weisende Fläche des Ventils teilweise mit der in das Sackinnere weisenden Fläche der Entlüftungsvorrichtung des Typs A verbunden ist, so dass ein Teil der nach innen weisenden Fläche der Entlüftungsvorrichtung des Typs A die innere Bodenfläche des Ventilsacks in diesem Bereich bildet und die Entlüftungsvorrichtung A eine Entlüftungskammer entlang des Bodens bildet, wobei die Entlüftungskammer auf der Seite des Ventils geschlossen ist.In another embodiment, the cross-bottom bag is characterized in that the bag-facing surface of the valve is partially connected to the inside of the sack facing surface of the venting device of type A, so that a part of the inwardly facing surface of the venting device type A, the inner Bottom surface of the valve bag in this area forms and the venting device A forms a vent chamber along the bottom, wherein the vent chamber is closed on the side of the valve.

Erfindungsgemäß wird die Entlüftungsvorrichtung (A) als schlauchförmige Entlüftungskammer ausgebildet. Hierbei wird die innere Oberfläche der Entlüftungskammer vollständig oder fast vollständig durch ein Stück luftdurchlässigen Materials gebildet, welches bevorzugt als Zettel bezeichnet wird, das lediglich den Durchtritt von Luft oder anderen, ähnlichen gasförmigen Stoffen gewährleistet. Ferner wird erfindungsgemäß das luftdurchlässige Material über die gesamte Öffnung des Ventilbodens befestigt, insbesondere verklebt, so dass ein Entweichen des Füllstoffes nicht möglich ist.According to the invention, the ventilation device (A) is designed as a tubular venting chamber. Here, the inner surface of the breather chamber is completely or almost completely formed by a piece of air-permeable material, which is preferably referred to as a slip, which ensures only the passage of air or other similar gaseous substances. Further, according to the invention, the air-permeable material is attached over the entire opening of the valve bottom, in particular glued, so that escape of the filler is not possible.

In einer Alternative der Erfindung hat das luftdurchlässige Material bevorzugt eine rechteckige Form und wird auf die Seitenklappen (Laschen) des Sackes, bevorzugt symmetrisch, angebracht, insbesondere geklebt. Die Größe des Zettels luftdurchlässigen Materials richtet sich nach der Größe der Laschen.
In einer Ausführung der Erfindung richtet sich nach der Größe des luftdurchlässigen Materials nach der Öffnung welche die Laschen bilden, so daß entlang dieser Lasche ein vom luftdurchlässigen Material nichtbedeckter Streifen von 0,1 bis 5,0 cm, bevorzugt 0,2 bis 2,5 cm; 0,2 bis 2,0 cm; 0,5 bis 1,5 cm; besonders bevorzugt 1,0 cm bleibt. Die Laschen werden dann so gefaltet und miteinander verbunden, daß sie eine Überlappung aufweisen, wobei die innere Oberfläche der Entlüftungskammer bis auf einen oben beschriebenen vom luftdurchlässigen Material nichtbedeckter Streifen fast vollständig durch einen Zettel luftdurchlässigen Materials gebildet wird. Dieser vom luftdurchlässigen Material nichtbedeckter Streifen ist der freie Rand einer Lasche.In an alternative of the invention, the air-permeable material preferably has a rectangular shape and is on the side flaps (tabs) of the bag, preferably symmetrically mounted, in particular glued. The size of the slip of air-permeable material depends on the size of the tabs.
In one embodiment of the invention depends on the size of the air-permeable material after the opening which form the tabs, so that along this tab from unpermitted by the air-permeable material strip from 0.1 to 5.0 cm, preferably 0.2 to 2.5 cm; 0.2 to 2.0 cm; 0.5 to 1.5 cm; more preferably 1.0 cm remains. The tabs are then folded and joined together so as to have an overlap, the inner surface of the venting chamber being formed almost entirely by a slip of air permeable material except for an air-permeable non-covered strip described above. This uncovered by the air-permeable material strip is the free edge of a tab.

Die Überlappung der Laschen wirkt sich in dieser Ausführung auch auf die Größe des Zettels aus, insbesondere auf die Breite des vom luftdurchlässigen Material nichtbedeckten Streifens der zweiten, äußeren Lasche. Dieser Streifen darf demgemäß nicht so breit sein, dass er Teil der inneren Oberfläche der Entlüftungskammer ist. Ferner soll in einer Ausführung der Erfindung der Zettel auf der äußeren Lasche nachThe overlap of the tabs in this embodiment also has an effect on the size of the tab, in particular on the width of the strip, not covered by the air-permeable material, of the second, outer tab. Accordingly, this strip must not be so wide that it is part of the inner surface of the venting chamber. Furthermore, in one embodiment of the invention, the label on the outer flap after

Faltung die innere Lasche ebenfalls überlappen.Folding the inner flap also overlap.

In einer anderen Alternative ist das luftdurchlässige Material größer als die von den Laschen gebildete Öffnung und ragt über den Rand einer oder beider Laschen hinaus. Nach Umfalten und Überlappen der Laschen wird hier die innere Oberfläche der Entlüftungskammer vollständig durch den Zettel luftdurchlässigen Materials gebildet.In another alternative, the air-permeable material is larger than the opening formed by the tabs and protrudes beyond the edge of one or both tabs. After folding over and overlapping the tabs here is the inner surface of the breather chamber completely formed by the slip of air-permeable material.

In einer weiteren Alternative schließt der Zettel luftdurchlässigen Materials mit dem Rand einer oder beider Laschen ab.
Wesentlich für die Entlüftungsvorrichtung des Typs A ist die schlauchförmige Ausgestaltung, die an jenem Ende, an der sie mit der Einfüllvorrichtung verbunden ist, geschlossen ist und an dem anderen Ende, zum Sackäußeren hin, offen ist. Durch den Bereich der Entlüftungskammer des Typs A der den Sackboden bildet entweicht die Luft bzw. das Gas aus dem Sackinneren zunächst in die Kammer und anschließend über die Öffnung in die umgebende Atmosphäre.In another alternative, the slip of air-permeable material closes with the edge of one or both tabs.
Essential to the venting device of type A is the tubular construction, which is closed at the end at which it is connected to the filling device and at the other end, towards the outside of the bag, open. Through the area of the venting chamber of type A forming the bag bottom, the air or gas escapes from the bag interior first into the chamber and then through the opening into the surrounding atmosphere.

In jeder der oben beschriebenen Varianten bezüglich der Entlüftungsvorrichtung ist jeweils eine Ausführung möglich, in der die Laschen nach dem Umfalten nicht überlappen. Auch hier sind zwei Varianten möglich, nämlich dass die bündig zueinander abschließen oder in einem freien Abstand zueinander angeordnet sind.In each of the variants described above with respect to the ventilation device, an embodiment is possible in each case in which the tabs do not overlap after folding. Again, two variants are possible, namely that they are flush with each other or arranged at a free distance from each other.

In der anderen, zu den Laschen senkrechten Ausrichtung oberhalb der Ventilbodeneinschläge, also zwischen Bodeneinschlag und Ventilkante, richtet sich die Ausmaße des luft- und/oder gasdurchlässigen Materials nach der Breite der Laschen, nämlich bis zu den Bodeneinschnitten, so dass ein Entweichen des Füllguts nicht möglich ist.In the other, perpendicular to the lugs alignment above the valve bottom, ie between bottom impact and valve edge, the dimensions of the air and / or gas-permeable material according to the width of the tabs, namely up to the bottom incisions, so that an escape of the contents not is possible.

Auf der einen Seite ist der Zettel luft- und/oder gasdurchlässigen Materials formschlüssig mit der zum Sackäußeren weisenden Fläche der Einfüllvorrichtung verbunden auf der anderen Seite mit dem Bodeneinschlag.On the one hand, the slip of air and / or gas permeable material is positively connected with the side facing the outside of the bag filling device on the other side with the bottom impact.

Nach der Faltung der Laschen werden diese auf der einen Seite, oberhalb der Einfüllvorrichtung, mit der Einfüllvorrichtung und gegebenenfalls mit dem darunter liegenden Zettel des luft- und/oder gasdurchlässigen Materials, und gegebenenfalls im Bereich der Überlappung, fest miteinander verbunden, bevorzugt verleimt bzw verklebt. Auch die gefalteten Teile des luftdurchlässigen Materials werden gegebenenfalls am Rand der Einfüllvorrichtung fest miteinander verbunden, bevorzugt verleimt bzw verklebt. Die gegenüber liegende Seite bleibt offen, so dass die erfindungsgemäße Entlüftungskammer gebildet wird. Der Ventilbodeneischlag gegenüber dem Ventil wird somit nicht mit den Laschen verbunden.After folding the tabs, these are on one side, above the Filling, with the filling device and optionally with the underlying slip of the air and / or gas-permeable material, and optionally in the region of the overlap, firmly bonded together, preferably glued or glued. The folded parts of the air-permeable material are optionally firmly connected to one another at the edge of the filling device, preferably glued or glued. The opposite side remains open, so that the venting chamber according to the invention is formed. The valve floor mixing against the valve is thus not connected to the tabs.

Der erfindungsgemäße Kreuzbodensack hat in einer weiteren Ausführung eine Entlüftungsvorrichtung des Typs B in Form einer zum Sackinneren geöffneten Tasche zwischen Bodeneinschlag und den beiden Laschen gebildet aus den Seitenwänden aufweist.
Die Entlüftungsvorrichtung B die Form einer zum Sackinneren geöffneten Tasche auf, die zwischen Bodeneinschlag und den beiden Laschen angeordnet ist. Die Entlüftungsvorrichtung B ist mit dem Bodeneinschlag und den Laschen verbunden, bevorzugt verklebt.The crossfloor bag according to the invention has in a further embodiment, a venting device of the type B in the form of an open to the bag interior pocket between bottom impact and the two tabs formed from the side walls.
The venting device B in the form of a bag open to the bag interior, which is arranged between the bottom flap and the two tabs. The breather B is connected to the bottom flap and the tabs, preferably glued.

Die Entlüftungsvorrichtung B wird vollständig oder fast vollständig aus einem als Zettel oder Filter bezeichneten rechteckigen, luft- und/oder gasdurchlässigen Material gebildet, das lediglich den Durchtritt von Luft oder anderen, ähnlichen gasförmigen Stoffen gewährleistet. In einer Alternative handelt es sich um dasselbe Material aus dem auch die Entlüftungsvorrichtung A gebildet ist.The breather B is completely or almost completely formed from a designated as a label or filter rectangular, air and / or gas-permeable material, which ensures only the passage of air or other similar gaseous substances. In an alternative, it is the same material from which the venting device A is formed.

Dieser Zettel wird parallel zu einem Seitenrand, vorzugsweise in der Mitte, gefaltet. Aber auch eine asymmetrische Faltung ist möglich.
Die beiden Seiten, die an die Faltung grenzen, werden and den Rändern senkrecht zur Faltung verschlossen, bevorzugt miteinander verklebt, so dass sich eine Tasche mit drei verschlossenen Rändern bildet, wobei die vierte Seite eine Öffnung parallel zur Faltung darstellt. Somit bildet die Entlüftungsvorrichtung B eine Tasche.
Die Öffnung kann sich über die gesamte Länge der Ränder des Zettels oder lediglich über einen Teilbereich, bevorzugt in der Mitte, erstrecken. Die Randbereiche werden dann verschlossen, bevorzugt miteinander verklebt.This piece of paper is folded parallel to a side edge, preferably in the middle. But also an asymmetric folding is possible.
The two sides bordering the fold are closed at the edges perpendicular to the fold, preferably glued together, so that a pocket with three closed edges is formed, the fourth side being an opening parallel to the fold. Thus, the venting device B forms a pocket.
The opening may extend over the entire length of the edges of the paper or only over a partial region, preferably in the middle. The border areas become then closed, preferably glued together.

Die obere und untere Seite der Tasche wird nun mit Bodeneinschlag und Laschen verbunden, bevorzugt verklebt. Dabei wird die Entlüftungsvorrichtung B so angeordnet, dass die Öffnung zum Sackinneren weist, bzw. sich im Sackinneren befindet. Ferner ist darauf zu achten, dass der Rand der oberen und unteren äußeren Fläche der Entlüftungsvorrichtung B vollständig mit den Sackelementen verbunden, bevorzugt verklebt werden. So kann das Schüttgut nicht entweichen. Entlang der Faltung liegt somit ein nichtverbundener Bereich vor, durch den die Luft aus dem Sackinneren entweichen kann und der somit als Filter dient.The upper and lower side of the bag is now connected to ground impact and tabs, preferably glued. In this case, the venting device B is arranged so that the opening facing the interior of the bag, or is located in the bag interior. Furthermore, it is important to ensure that the edge of the upper and lower outer surface of the breather B are completely connected to the bag elements, preferably glued. So the bulk material can not escape. Along the fold is thus an unbonded area, through which the air can escape from the bag interior and thus serves as a filter.

Wesentlich für die Entlüftungsvorrichtung des Typs B ist die taschenförmige Ausgestaltung, die eine Öffnung zum Sackinneren hat und zum Sackäußeren hin verschlossen ist. Durch die Öffnung entweicht die Luft bzw. das Gas aus dem Sackinneren zunächst in die Tasche der Entlüftungsvorrichtung B und anschließend über den nicht mit anderen Elementen des Ventilsacks verbundenen Bereich des luft- und/oder gasdurchlässige Material (entspricht also einem Taschenboden) in die umgebende Atmosphäre.Essential for the venting device of the type B is the pocket-like configuration, which has an opening to the bag interior and is closed to the outside of the bag. Through the opening, the air or gas escapes from the interior of the bag first in the bag of the breather B and then on the not connected to other elements of the valve bag portion of the air and / or gas-permeable material (ie corresponds to a bottom pocket) in the surrounding atmosphere ,

In einer Ausführung sind Einfüllvorrichtung und Entlüftungsvorrichtung B übereinander angeordnet, bevorzugt ist Entlüftungsvorrichtung B zwischen Einfüllvorrichtung und dem Bodeneinschlag angeordnet. Dabei ist der Rand der in das Sackinnere weisenden Fläche der Einfüllvorrichtung mit einer Fläche der Entlüftungsvorrichtung B verbunden, bevorzugt verklebt. Das heisst, der Rand der Entlüftungsvorrichtung B ist statt mit den Laschen hier mit der Einfüllvorrichtung verbunden. Die andere Fläche der Entlüftungsvorrichtung B ist mit dem Bodeneinschlag verbunden, bevorzugt verklebt.In one embodiment, the filling device and the ventilation device B are arranged one above the other, preferably the ventilation device B is arranged between the filling device and the bottom impact. In this case, the edge of the pointing into the bag interior surface of the filling device is connected to a surface of the breather B, preferably glued. That is, the edge of the venting device B is connected here with the filling device instead of the tabs. The other surface of the breather B is connected to the ground impact, preferably glued.

In einer anderen Ausführung sind beide Entlüftungsvorrichtungen A und B übereinander angeordnet, bevorzugt ist Entlüftungsvorrichtung B zwischen Entlüftungsvorrichtung A und dem Sackinneren, beziehungsweise Bodeneinschlag angeordnet.In another embodiment, both venting devices A and B are arranged one above the other, preferably venting device B is arranged between venting device A and the interior of the bag or bottom flap.

In einer weiteren Alternative ist mindestens eine Entlüftungsvorrichtung B in einer Eckfaltung angeordnet, die sich an dem Sackende befindet, das keine Einfüllvorrichtung aufweist.In a further alternative, at least one ventilation device B in one Corner folded arranged, which is located at the bag end, which has no filling device.

In weiteren Alternativen umfasst der erfindungsgemäße Ventilsack mindestens zwei Entlüftungsvorrichtungen B. Eine Entlüftungsvorrichtung B befindet sich dann in der Eckfaltung, in welchem die Einfüllvorrichtung zu finden ist und eine weitere Entlüftungsvorrichtung B zum Beispiel in der Eckfaltung mit der Entlüftungsvorrichtung A oder am entgegengesetzte Ende. Möglich sind auch drei oder vier Entlüftungsvorrichtungen B.In further alternatives, the valve bag according to the invention comprises at least two ventilation devices B. A ventilation device B is then in the corner fold, in which the filling device is to be found and another venting device B, for example, in the corner fold with the venting device A or at the opposite end. Also possible are three or four deaerators B.

In einer Ausführung der Erfindung wird der gefaltete Zettel der Entlüftungsvorrichtung B an den Seitenrändern senkrecht zur ersten Faltung, entsprechend den Laschen des Ventilsacks, gefaltet. Diese zweite Faltung kann auch um die Einfüllvorrichtung bzw. das Ventil oder um die Entlüftungsvorrichtung A erfolgen. Die Bereiche, mindestens die Ränder dieser Teilbereiche des Zettels, werden miteinander sowie mit Einfüllvorrichtung bzw. das Ventil oder Entlüftungsvorrichtung A und den Laschen verbunden, bevorzugt verklebt.In one embodiment of the invention, the folded slip of the breather B is folded at the side edges perpendicular to the first fold corresponding to the flaps of the valve bag. This second folding can also take place around the filling device or the valve or around the ventilation device A. The areas, at least the edges of these subregions of the booklet, are connected to one another and preferably to the filling device or the valve or venting device A and the tabs.

In einer Ausführung sind Einfüllvorrichtung und Entlüftungsvorrichtung B in derselben Eckfaltung angeordnet, wobei der Ventilsack keine Entlüftungsvorrichtung A aufweist. Auch hier sind noch weitere Entlüftungsvorrichtungen B möglich.In one embodiment, filling device and venting device B are arranged in the same corner fold, the valve bag having no venting device A. Again, even more ventilation devices B are possible.

Erfindungsgemäß kann der Ventilboden über den Laschen auch mit einem zusätzlichen Deckblatt versehen werden.According to the invention, the valve bottom over the tabs can also be provided with an additional cover sheet.

In einer Ausführung des erfindungsgemäßen Kreuzbodensacks liegt eine weitere Entlüftungsvorrichtung des Typs C in Verbindung mit Typ A vor, enthaltend eine Öffnung in der Entlüftungsvorrichtung A in Längsrichtung des Bodens zum Sackäußeren hin und eine Öffnung zwischen Deckblatt des Ventilbodens und der darunterliegenden Seitenlasche.
In einer Ausführung erfolgt somit die Verbindung, bevorzugt Verklebung, der Überlappung des Zettels für die Entlüftungskammer sowie die Verbindung Seitenlasche-Deckblatt im Bereich des bezüglich der Überlappung inneren Lasche, vorzugsweise nicht durchgängig, um den Luftaustritt über diese klebstoff-freien Bereiche zu ermöglichen.
Das heißt in einem Bereich in gedachter Verlängerung der Öffnung der Entlüftungsvorrichtung A ist das Deckblatt nicht mit der darunterliegenden Seitenlasche verbunden. Bei den Öffnungen, also den Bereichen die nicht verbunden sind, handelt es sich um Abschnitte von 10 cm, 9 cm, 8 cm, 7 cm, 6 cm, 5 cm, 4 cm, 3,5 cm, 3 cm, 2,5 cm, 2 cm, 1,5 cm, 1 cm, bevorzugt proportional zur Länge des Sackbodens, sowohl bezüglich der Öffnung in der Entlüftungsvorrichtung A in Längsrichtung des Bodens zum Sackäußeren hin sowie der Öffnung zwischen Deckblatt des Ventilbodens und der darunterliegenden Seitenlasche.
In diesem Falle ist eine Verklebung an den überlappenden Bereichen der Laschen nicht erforderlich, kann aber erfolgen. Falls die Laschen nicht überlappen erfolgt die nicht durchgängige Verbindung auf einer beliebigen Seite.In one embodiment of the crosshead sack of the present invention, there is another Type C venting device in conjunction with Type A, including an opening in the venting device A in the longitudinal direction of the bottom toward the bag exterior and an opening between the cover sheet of the valve bottom and the underlying side flap.
In one embodiment, therefore, the connection, preferably bonding, the overlap of the tab for the venting chamber and the connection takes place Side flap cover sheet in the region of the inner flap with respect to the overlap, preferably not continuously, to allow the air outlet over these adhesive-free areas.
That is, in a range in imaginary extension of the opening of the venting device A, the cover sheet is not connected to the underlying side flap. The openings, ie the areas that are not connected, are sections of 10 cm, 9 cm, 8 cm, 7 cm, 6 cm, 5 cm, 4 cm, 3.5 cm, 3 cm, 2.5 cm, 2 cm, 1.5 cm, 1 cm, preferably in proportion to the length of the bag bottom, both with respect to the opening in the venting device A in the longitudinal direction of the bottom to the bag exterior and the opening between the cover sheet of the valve bottom and the underlying side flap.
In this case, an adhesion to the overlapping areas of the tabs is not required, but can take place. If the tabs do not overlap, the non-continuous connection is on any side.

Das Deckblatt ist ferner fest verbunden, bevorzugt verklebt mit dem zum Sackäußeren weisenden Fläche der Einfüllvorrichtung und Sackwand. Auch dies bewirkt ein sicheres Anheben des Sackbodens zum automatisierten Öffnen des Ventil für den Einfüllstutzen. Die gegenüber liegende Seite des Deckblatt wird nicht mit dem Sack verbunden. Dadurch bleibt die Entlüftungskammer offen und der Luftaustritt wird nicht gehindert. Auf dieser Seite kann das Deckblatt verkürzt sein im Vergleich zur gegenüber liegenden Seite, also nicht symmetrisch zur Sackmitte.The cover sheet is also firmly connected, preferably glued to the side facing the bag exterior surface of the filling and bag wall. This also causes a safe lifting of the bag bottom for automated opening of the valve for the filler neck. The opposite side of the cover sheet is not connected to the bag. As a result, the vent chamber remains open and the air outlet is not hindered. On this page, the cover page can be shortened compared to the opposite side, so not symmetrical to the bag center.

Varianten des Kreuzbodensacks weisen jeweils eine der Entlüftungsvorrichtungen A, B oder C auf oder jede beliebige Kombination: A und B, A und C, oder A und B und C. Weitere Varianten enthalten 2, 3 oder 4 Entlüftungsvorrichtungen B und gegebenenfalls zusätzlich A und/oder C.Variants of the cross-bottom bag each have one of the venting devices A, B or C or any combination: A and B, A and C, or A and B and C. Further variants contain 2, 3 or 4 venting devices B and optionally additionally A and / or C.

In einer weiteren Variante der Erfindung weist das Deckblatt einseitig oder beidseitig einen Umschlag auf die Seitenwände welche die Laschen bilden auf.
Ferner kann das Deckblatt einen Längseinschlag aufweisen.In a further variant of the invention, the cover sheet has on one or both sides an envelope on the side walls which form the tabs.
Furthermore, the cover sheet may have a longitudinal impact.

Die oben beschriebenen Ausgestaltungen des Kreuzbodensacks haben den Vorteil, dass eine optimale Entlüftung gewährleistet ist. Denn durch das luftdurchlässige Material können nur Luft oder andere, ähnliche gasförmige Stoffe hindurch treten. Auf der anderen Seite ist das Filterpapier durch die darüber angeordnete luftundurchlässige feste Schicht geschützt. Beschädigungen beim Handhaben des Papiersacks werden damit weitgehend verhindert. Zudem hat die Anordnung der Entlüftungsvorrichtung unmittelbar im Bereich des Einfüllschlauchs den Vorteil, dass eine optimierte Entlüftung gewährleistet ist, auch bei luftdichten Säcken. Ein Befüllen des Papiersacks ist damit erheblich erleichtert.The above-described embodiments of the cross-bottom bag have the advantage that optimum ventilation is ensured. Because only air or other, similar gaseous substances can pass through the air-permeable material. On the other hand, the filter paper is protected by the airtight layer above it. Damage when handling the paper bag are thus largely prevented. In addition, the arrangement of the ventilation device directly in the region of the filling hose has the advantage that an optimized ventilation is ensured, even in airtight bags. A filling of the paper bag is thus considerably easier.

Allgemein werden für das Verkleben der nach außen weisenden Fläche der Elemente des Kreuzbodensacks übliche Klebstoffe eingesetzt zum Beispiel Leim, Stärke-Kleber, Dispersionskleber usw..In general, conventional adhesives are used for bonding the outwardly facing surface of the elements of the cross-bottom sack, for example glue, starch adhesive, dispersion adhesive, etc.

Als Material für die Papiersäcke kommen übliche Stoffe in Betracht, zum Beispiel Kraftsackpapier.As material for the paper sacks usual materials come into consideration, for example sack kraft paper.

In einer Ausführung enthält der erfindungsgemäße Papiersack eine Sperrschicht. Diese Sperrschicht ist eine Folie oder ein beschichtetes Material ist.In one embodiment, the paper bag according to the invention contains a barrier layer. This barrier layer is a foil or a coated material.

In einer Ausführung kann sich zwischen den Doppellagen aus Papier eine Folie befinden. Die Folie kann aus einer oder zwei oder mehreren Bahnen bestehen die parallel zueinander vom Oberteil zum Unterteil des Sacks verlaufen. Jeweils ein Rand einer Bahn kann an die Innen -oder Außenlage aus Papier befestigt sein, während jeweils ein freier Rand einen befestigten Rand überlappen kann. Die Folie kann entlang der Längsnaht auch verklebt sein, womit der Sack hermetisch abgeschlossen wäre.In one embodiment, there may be a film between the double layers of paper. The film may consist of one or two or more webs extending parallel to each other from the top to the bottom of the bag. One edge of a web can be attached to the inner or outer layer of paper, while each free edge can overlap a fixed edge. The film may also be glued along the longitudinal seam, whereby the bag would be hermetically sealed.

Ausgehend von der gemäß GemPSI (Gemeinschaft Papiersackindustrie eV) verwendeten Bezeichnung, bei welcher der Ventilsack so auf seiner Längsnaht liegt, daß diese sich von oben gesehen in der rechten Sackhälfte befindet, kann erfindungsgemäß die Einfüllvorrichtung und die Entlüftungsvorrichtung oben oder unten und links oder rechts eingefügt sein.Starting from the designation used in accordance with GemPSI (Community Paper Bag Industry), in which the valve bag lies on its longitudinal seam so that it is located in the right-hand side of the bag, as seen from above, the filling device and the venting device can be arranged at the top or bottom and be inserted left or right.

Die erfindungsgemäßen Säcke werden verwendet für Schüttgut, bevorzugt feinkörniges Schüttgut wie Lebensmittel, Tierfutter, Gips, Zement, Granulat, Düngemittel, chemische Grundstoffe usw. die gekörnt, granuliert, pulverförmig oder in Brocken als Packgut anfallen.The bags according to the invention are used for bulk goods, preferably fine-grained bulk material such as food, animal feed, gypsum, cement, granules, fertilizers, chemical precursors, etc., which are granulated, granulated, powdered or broken up as packaged goods.

Im Folgenden wird die Erfindung unter Bezugnahme auf die Figuren näher beschrieben. Es handelt sich dabei um eine lediglich schematische Darstellung in welcher sie Maßstäbe und Verhältnisse der einzelnen Elemente zueinander zu Gunsten einer besseren Erkennung vernachlässigt wurden:

Gemäß Figuren wird der Kreuzbodensack 1 mit Wandteilen 2 und 3 an einem Ende mittels eines Innenriegels 7 verschlossen, der mit Seitenlaschen 10, 11 und Bodeneinschlag 8, 9 so verbunden ist, so dass kein Füllgut entweichen kann. Seitenlaschen 10, 11 und Innenriegel werden entlang Falz 16, 17 parallel zu Längssache 14 des Bodens gefaltet und verklebt, so dass ein Spalt zwischen den Seitenkanten 12 und 13 der Seitenlaschen über dem Aufreißstreifen bleibt. Darauf wird das Deckblatt 4 angebracht.According to figures, the cross-bottom bag 1 is closed with wall parts 2 and 3 at one end by means of an inner bar 7 which is connected to side flaps 10, 11 and bottom cover 8, 9, so that no filling material can escape. Side flaps 10, 11 and inner bars are folded and glued along folds 16, 17 parallel to the longitudinal direction 14 of the bottom so that a gap between the side edges 12 and 13 of the side flaps remains above the tear strip. Then the cover sheet 4 is attached.

Innenriegel und Deckblatt können unabhängig voneinander symmetrisch oder asymmetrisch bezüglich der Längsachse 14 oder der Querachse 15 angebracht werden.Inner bar and cover sheet can be mounted independently of each other symmetrically or asymmetrically with respect to the longitudinal axis 14 or the transverse axis 15.

Das Deckblatt 4 weist den integrierten Tragegriff 5 auf, der zwischen den Schnitten 5' gebildet wird.The cover sheet 4 has the integrated carrying handle 5, which is formed between the cuts 5 '.

An Aufreißstreifen 6 kann durch Ziehen der Sack geöffnet werden, wobei der Innenriegel 7 reißt und Deckblatt 4 ohne Einreißen abgelöst wird.At tear strip 6 can be opened by pulling the bag, wherein the inner bar 7 breaks and cover sheet 4 is detached without tearing.
