Description

Die vorliegende Erfindung betrifft einen Ventilsack mit 2 unterschiedlichen Entlüftungsvorrichtungen.The present invention relates to a valve bag with two different venting devices.

Aus der DE-A-41 402 13 ist bekannt, neben einem Füllventil im Bereich des einen Eckeinschlags und ein Entlüftungsventil im gegenüberliegenden Eckeinschlag des Kreuzbodens zu verwenden. Doch reicht diese Wirkung zur Entlüftung der Ventilsäcke nicht aus.From the DE-A-41 402 13 It is known to use in addition to a filling valve in the region of a corner impact and a vent valve in the opposite corner of the crossbeam. But this effect is not sufficient for venting the valve bags.

Aus der DE 20 2007 004 838 U1 ist ein Ventilsack bekannt, bei dem ein Entlüftungssystem aus luftdurchlässigem Papier (HD-Papier) vorgesehen ist, das den Durchtritt des Produkts verhindert. Dies wird auf den noch nicht endgültig gefalteten Boden aufgelegt und mit diesem verklebt. Die Größe des Zettels ist so gewählt, dass er einerseits das Schlauchventil nicht berührt und andererseits über das Material des Bodens übersteht und aufgrund dessen anschließend in Richtung auf den Seitenrand umgefaltet werden kann. Dadurch entsteht eine Tasche, die zum Seitenrand hin offen ist. Darauf wird der Kreuzboden verklebt.From the DE 20 2007 004 838 U1 a valve bag is known in which a ventilation system made of air-permeable paper (HD paper) is provided, which prevents the passage of the product. This is placed on the not yet finally folded soil and glued to it. The size of the billet is chosen so that it does not touch the hose valve on the one hand and on the other hand protrudes beyond the material of the soil and can then be folded over in the direction of the side edge. This creates a bag that is open to the side edge. Then the crossbore is glued.

Aus der EP 0 767 105 B1 ist ein Ventilsack bekannt, bei dem ein Filterblatt in dem Ventilboden integriert ist. Zur guten Luftdurchlässigkeit des Materials vom Filterblatt wird eine Mikronadelung verwendet. Den Abschluß des Ventilsacks bildet ein mit Luftschlitzen versehenes Deckblatt. Für den optimierten Luftdurchlass wird das rechtecksförmige Deckblatt mit Unterbrechungen nur in seinem Randbereich an den beiden ungefalteten Seitenklappen und dem Ventilkörper sowie dem Eckeinschlag festgeklebt.From the EP 0 767 105 B1 a valve bag is known in which a filter sheet is integrated in the valve bottom. For good air permeability of the material from the filter sheet a micro needling is used. The conclusion of the valve bag forms a louvered cover sheet. For the optimized air passage, the rectangular top sheet is glued with interruptions only in its edge region on the two unfolded side flaps and the valve body and the corner impact.

Der Ventilsack gemäß der EP 0 761 05 B1 hat den Nachteil, dass durch das mit Luftschlitzen versehene Deckblatt und das perforierte Filterblatt Feuchtigkeit eindringen kann. Ferner ist der freiliegende Mittelabschnitt des Filterblattes gefährdet, vor allem kann es hier zu Beschädigungen bei der Lagerung und Transport der Säcke kommen.The valve bag according to the EP 0 761 05 B1 has the disadvantage that moisture can penetrate through the louvered cover sheet and the perforated filter sheet. Furthermore, the exposed center portion of the filter sheet is at risk, especially there may be damage during storage and transport of the bags.

Die DE 1806333 A1 betrifft einen Sack mit einer Luftaustrittsöffnung, bei dem unter den Bodenklappen ein luftdurchlässiger Schlauch eingearbeitet ist, wobei zumindest sein eines Ende durch die Bodenverklebung hindurchführt.
In der EP 060599 B1 werden Kunststoffsäcke mit einem Füllventil beschrieben. Auf der gegenüberliegenden Seite des Füllventils ist in einem Ecklappen eine Tasche aus Kunststoff angebracht, die bis an das Sackinnere reicht. Diese Tasche ermöglicht die Entlüftung des Kunststoffsacks.
Die EP 0291128 A1 betrifft einen Ventilsack aus Kunststoff, bei dem die eine Seite des Ventils, die zum Sackinneren zeigt aus einem luftdurchlässigen Filtermaterial besteht und die Entlüftung ermöglich.
Aus der EP 2 345 595 A1 ist ein Ventilsack mit einer schlauchförmigen Entlüftungsvorrichtung gegenüberliegend der Einfüllvorrichtung.
In der DE 41 40 213 A1 wird ein Ventilsack mit einem Entlüftungsventil beschrieben, das durch einen in einer Eckfaltung eingearbeiteten Filtermaterialzuschnitt geschlossen ist. Dabei befindet sich dieses Entlüftungsventil nicht in jener Eckfaltung in welcher sich der Einfüllstutzen befindet. Weitere Ventisäcke sind aus DE202010000042U und DE9101210U bekannt. Die vorliegende Erfindung hat sich nunmehr die Aufgabe gestellt, die sich aus dem Stand der Technik ergebenden Nachteile zu überwinden. Des Weiteren soll der Ventilsack so entlüftet werden, dass die Befüllung störungsfrei, d.h. ohne Staubentwicklung, Sackplatzer sowie mit optimalen Abfüllzeiten abläuft und ein entsprechender Produktschutz des befüllten Sackes und eine hohe Befüllgenauigkeit gewährleistet ist.
Um optimale Abfüllzeiten zu gewährleisten, ist eine schnelle Entlüftung von besonderer Bedeutung.The DE 1806333 A1 relates to a bag with an air outlet opening, in which under the bottom flaps an air-permeable hose is incorporated, wherein at least one end passes through the Bodenverklebung.
In the EP 060599 B1 Plastic bags are described with a filling valve. On the opposite side of the filling valve, a pocket made of plastic is attached in a corner flap, which extends to the inside of the bag. This bag allows the venting of the plastic bag.
The EP 0291128 A1 relates to a valve bag made of plastic, in which one side of the valve, which points to the interior of the bag consists of an air-permeable filter material and allows venting.
From the EP 2 345 595 A1 is a valve bag with a tubular venting device opposite the filling device.
In the DE 41 40 213 A1 a valve bag is described with a vent valve, which is closed by a incorporated in a corner fold filter material blank. In this case, this vent valve is not in that corner fold in which the filler neck is located. Other Ventisäcke are out DE202010000042U and DE9101210U known. The present invention has now taken on the task of overcoming the disadvantages resulting from the prior art. Furthermore, the valve bag should be vented so that the filling runs smoothly, ie without dust, bag bursting and with optimal filling times and a corresponding product protection of the filled bag and a high filling accuracy is guaranteed.
To ensure optimal filling times, fast ventilation is of particular importance.

Diese Aufgabe wird erfindungsgemäß durch einen Ventilsack gemäß Anspruch 1 gelöst.This object is achieved by a valve bag according to claim 1.

In einer bevorzugten Ausführung handelt es sich bei dem erfindungsgemäßen Ventilsack um einen Kreuzbodensack aus Papier.
In einer Alternative umfasst die Einfüllvorrichtung ein Thermo-Ventil. Dabei handelt es sich um ein Ventil, das so mit Kunststoffbeschichtet ist, so dass nach Befüllen des Papiersacks dieser thermisch verschlossen werden kann.
Bevorzugt umfasst die Einfüllvorrichtung ein Thermo- Außenventil, das heisst, dieses ragt nach außen in Bezug auf den Bodeneinschlag und/oder die Laschen. In a preferred embodiment, the valve bag according to the invention is a cross-bottom bag made of paper.
In an alternative, the filling device comprises a thermo-valve. It is a valve, which is coated with plastic, so that after filling the paper bag, this can be thermally sealed.
Preferably, the filling device comprises a thermo-outer valve, that is, this protrudes outward with respect to the ground impact and / or the tabs.

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.
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.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 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 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 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 nach Faltung die innere Lasche ebenfalls überlappen.The 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 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 for the venting device of the 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, to the outside of the bag, is open. Through the area of the deaeration chamber of the type (A) forms the bag bottom, the air or gas escapes from the bag interior first in the chamber and then through the opening into the surrounding atmosphere.

Erfindungsgemäß weist die Entlüftungsvorrichtung des Typs (B) die Form einer zum Sackinneren geöffneten Tasche auf , die zwischen Bodenbeschlag und den beiden Laschen angeordnet ist. Die Entlüftungsvorrichtung des Typs (B) ist mit dem Bodenbeschlag und den Laschen verbunden, bevorzugt verklebt.According to the invention, the venting device of the type (B) in the form of a bag open to the bag interior, which is arranged between the bottom fitting and the two tabs. The venting device of the type (B) is connected to the bottom fitting and the tabs, preferably glued.

Die Entlüftungsvorrichtung des Typs (B) (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 des Typs (A) gebildet ist. 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 des Typs (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.
Die obere und untere Seite der Tasche wird nun mit Bodenbeschlag und Laschen verbunden, bevorzugt verklebt. Dabei wird die Entlüftungsvorrichtung des Typs (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 des Typs (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 venting device of type (B) (B) is formed entirely or almost entirely from a rectangular, air and / or gas permeable material, referred to as a slip or filter, which merely ensures the passage of air or other similar gaseous substances. In an alternative, it is the same material from which the venting device of type (A) is formed. 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 breather of the type (B) forms a bag. 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 edge regions are then closed, preferably glued together.
The upper and lower side of the bag is now connected to bottom fitting and tabs, preferably glued. In this case, the ventilation device of the type (B) is arranged so that the opening facing the interior of the bag, or is located in the bag interior. It should also be noted that the edge of the upper and lower outer surfaces of the ventilation device of the type (B) are completely connected to the bag elements, preferably glued. So the bulk material can not escape. Along the fold there is thus a non-bonded 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 des Typs (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-shaped 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 into the pocket of the venting device of type (B) and then via the region of the air and / or gas-permeable material not connected to other elements of the valve bag (corresponding to a pocket bottom). in the surrounding atmosphere.

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

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

In einer weiteren Alternative ist mindestens eine Entlüftungsvorrichtung des Typs (B) in einer Eckfaltung angeordnet, die sich an dem Sackende befindet, das keine Einfüllvorrichtung aufweist.
In weiteren Alternativen umfasst der erfindungsgemäße Ventilsack mindestens zwei Entlüftungsvorrichtungen des Typs (B). Eine Entlüftungsvorrichtung (B) befindet sich dann in der Eckfaltung, in welchem die Einfüllvorrichtung zu finden ist und eine weitere Entlüftungsvorrichtung des Typs (B) zum Beispiel in der Eckfaltung mit der Entlüftungsvorrichtung des Typs (A) oder am entgegengesetzte Ende. Möglich sind auch drei oder vier Entlüftungsvorrichtungen des Typs (B).In a further alternative, at least one venting device of the type (B) is arranged in a corner fold, which is located at the bag end, which has no filling device.
In further alternatives, the valve bag according to the invention comprises at least two venting devices of the type (B). A venting device (B) is located then in the corner fold in which the filler is to be found and another breather of the type (B) for example in the corner fold with the venting device of type (A) or at the opposite end. Also possible are three or four venting devices of type (B).

In einer Ausführung der Erfindung wird der gefaltete Zettel der Entlüftungsvorrichtung des Typs (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 des Typs (A) erfolgen. Die Bereiche, mindestens die Ränder dieser Teilbereiche des Zettels, werden miteinander sowie mit der Einfüllvorrichtung bzw. dem Ventil oder der Entlüftungsvorrichtung des Typs (A) und den Laschen verbunden, bevorzugt verklebt.In one embodiment of the invention, the folded sheet of the venting device of type (B) is folded at the side edges perpendicular to the first fold, corresponding to the tabs of the valve bag. This second folding can also be done around the filling device or the valve or the ventilation device of the type (A). The areas, at least the edges of these subregions of the booklet, are joined together, preferably glued, to one another and to the filling device or the valve or the venting device of the type (A) and the tabs.

In einer nicht beanspruchten Ausführung sind Einfüllvorrichtung und Entlüftungsvorrichtung des Typs (B) in derselben Eckfaltung angeordnet, wobei der Ventilsack keine Entlüftungsvorrichtung des Typs (A) aufweist. Auch hier sind noch weitere Entlüftungsvorrichtungen des Typs (B) möglich.
In jeder der oben beschriebenen Varianten 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 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 an unclaimed embodiment, filling device and venting device of the type (B) are arranged in the same corner fold, the valve bag having no venting device of the type (A). Again, other venting devices of the type (B) are possible.
In each of the variants described above, 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 the other, perpendicular to the lugs alignment above the bottom of the valve, ie between bottom impact and valve edge, the dimensions of the air and / or gas-permeable material according to the width of the flaps, namely up to the bottom incisions, so that an escape of the filling material 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. 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.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. After the folding of the tabs, these are on the one side, above the filling device, 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 , Also the folded parts of the air-permeable Materials are optionally firmly connected together 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.

Erfindungsgemäß kann der Ventilboden über den Laschen auch mit einem zusätzlichen Deckblatt versehen werden.
In einer Ausführung erfolgt die Verbindung, bevorzugt Verklebung zum Deckblatt im Bereich des bezüglich der Überlappung inneren Lasche, vorzugsweise nicht durchgängig, um den Luftaustritt über diese klebstoff-freien Bereiche zu ermöglichen. 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.According to the invention, the valve bottom over the tabs can also be provided with an additional cover sheet.
In one embodiment, the connection is made, preferably bonding to the cover sheet in the region of the inner flap with respect to the overlap, preferably not continuously, in order to allow the air outlet via these adhesive-free areas. 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.

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 erfindungsgemäße Ausgestaltung des Ventilsacks, bevorzugt Papiersacks hat 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.The inventive design of the valve bag, preferably paper bag has the advantage that optimal 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.

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.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.

Für das Verkleben der nach außen weisenden Fläche der Entlüftungsvorrichtung werden übliche Klebstoffe eingesetzt zum Beispiel Leim, Stärke-Kleber, Dispersionskleber usw.For the bonding of the outwardly facing surface of the venting device conventional adhesives are used, 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 sack half, as seen from above, the filling device and the venting device can be inserted at the top or bottom and left or right be.

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 material, preferably fine-grained bulk material such as foodstuffs, animal feed, gypsum, cement, granules, Fertilizers, chemical raw materials, etc., which are granulated, granulated, powdered or chunky as packaged goods.

Erfindungsgemäß erfolgt die Befüllung mit dem Schüttgut über die schlauchförmige Einfüllvorrichtung mit Öffnung 4. Die Einfüllvorrichtung ragt einerseits bis in das Sackinnere. Auf der anderen Seite mit der Einfüllöffnung 4 kann sie beliebig über den Sackrand hinausragen, bevorzugt schließt sie jedoch mit dem Sackrand ab. Über diesen gelangt das Schüttgut in den Ventilsack 1. Infolge des Schüttvorgangs entsteht ein Sack mit rechtecksförmig ausgestalteten Wandteilen 2 und 21.According to the filling with the bulk material via the tubular filling device with opening 4. The filling device projects on the one hand into the bag interior. On the other side with the filling opening 4, it can project beyond the edge of the bag, but preferably it closes off with the edge of the bag. Through this the bulk material enters the valve bag 1. As a result of the bulk process creates a bag with rectangular shaped wall parts 2 and 21st

Die Deckfläche setzt sich aus der Einfüllvorrichtung mit Einfüllöffnung 4 und der Entlüftungsvorrichtung 5 zusammen. Die Einfüllvorrichtung mit Einfüllöffnung 4 besitzt die zum Sackäußeren weisende Fläche der Einfüllvorrichtung 6. In dem erfindungsgemäßen Beispiel ist die schlauchförmige Einfüllvorrichtung mit Einfüllöffnung 4 derart ausgestaltet, dass sie nur einen Teil der Deckfläche 3 des Ventilsacks 1 bedeckt. D.h. die Einfüllvorrichtung endet an der Kante. Im Anschluss daran und mit dem einen Ende der Einfüllvorrichtung verbunden, sowie mit dem Rand des Bodeneinschlags 7, 8 und den Laschen 11, 12 verbunden, befindet sich die Entlüftungsvorrichtung 5.The top surface is composed of the filling device with the filling opening 4 and the venting device 5 together. In the example according to the invention, the tubular filling device with filling opening 4 is designed such that it covers only a part of the top surface 3 of the valve sack 1. That the filling device ends at the edge. Subsequent thereto and connected to the one end of the filling device, as well as to the edge of the bottom cover 7, 8 and the tabs 11, 12, the venting device 5 is located.

Die Entlüftungsvorrichtung 5 ist in Form einer Luftkammer ausgebildet und besteht aus luftdurchlässigem Material 23, bevorzugt einem Filterpapier 23. Dies erstreckt sich bis zu den Seitenkanten 16 und 17 der Laschen 11 und 12 des Ventilsacks 1. D.h. das luftdurchlässige Material ist mit seinen Seitenkanten 14 und 15 in einem Abstand 9 wie oben definiert an die Laschen 11 und 12 fest und durchgängig 22 fixiert. Die dazu senkrechten Seitenränder 19 und 20 des luftdurchlässigen Materials sind in Teilen an die Seitenränder der Laschen 11 und 12 in Abstand 10 wie oben definiert, durchgängig fixiert 22' die senkrecht zu den Seitenkanten 16 und 17 der Laschen 11 und 12 verlaufen sowie an den Bodeneinschlag 8 beziehungsweise die Einfüllvorrichtung 22'.
Seitenrand 19 des luftdurchlässigen Materials und 18 der Einfüllvorrichtung überlappen.The venting device 5 is formed in the form of an air chamber and consists of luftdurchlässigem material 23, preferably a filter paper 23. This extends to the side edges 16 and 17 of the tabs 11 and 12 of the valve bag 1. That is, the air-permeable material is with its side edges 14 and 15 fixed at a distance 9 as defined above to the tabs 11 and 12 fixed and continuous 22. The perpendicular side edges 19 and 20 of the air-permeable material are in parts to the side edges of the tabs 11 and 12 at a distance 10 as defined above, continuously fixed 22 'which are perpendicular to the side edges 16 and 17 of the flaps 11 and 12 and to the bottom impact 8 and the filling device 22 '.
Side edge 19 of the air-permeable material and 18 of the filler overlap.

Die zwei Laschen 11 und 12 sowie die Bodeneinschläge sind gebildet aus den Wänden 2 des Sackes. Die Größe der beiden Laschen 11 und 12 ist derart gestaltet, dass sie sich in ihren Randbereichen mit den Seitenkanten 16 und 17 bei der Faltung bevorzugt mittig der Deckfläche überlappen und so die Überlappung 13 bilden.The two tabs 11 and 12 and the bottom impacts are formed from the walls 2 of the bag. The size of the two tabs 11 and 12 is designed such that they are in their edge regions with the side edges 16 and 17th preferably overlap in the middle of the top surface during folding and thus form the overlap 13.

Der Zettel für die Entlüftungsvorrichtung des Typs - (B) 27 wird entlang der Linie 28 parallel zu den Rändern 29 und 30 gefaltet. Im Falle einer symmetrischen Faltung liegen also die Ränder 29 und 30 übereinander. Senkrecht dazu liegen auch die Ränder 31 und 32 sowie 33 bzw. 34 übereinander. Diese Ränder 31 und 32 sowie 33 und 34 werden jeweils miteinander verbunden, bevorzugt verklebt. Somit bildet sich eine Tasche die an drei Seiten geschlossen ist und eine Öffnung 35 gegenüber der Faltung 28 aufweist.The sheet for the venting device of type - (B) 27 is folded along the line 28 parallel to the edges 29 and 30. In the case of a symmetrical folding so the edges 29 and 30 are superimposed. Perpendicular to the edges 31 and 32 and 33 and 34 are superimposed. These edges 31 and 32 and 33 and 34 are connected to each other, preferably glued. Thus, a pocket is formed which is closed on three sides and has an opening 35 opposite the fold 28.

Für die Anordnung der Entlüftungsvorrichtung des Typs (B) im Bereich des Eckeinschlags wird Rand 29 auf der äußeren Seite der Tasche mit dem Bodeneinschlages des Sackes verbunden und Rand 30, ebenfalls auf der äußeren Seite der Tasche, mit den Laschen verbunden, bevorzugt verklebt.For the arrangement of the venting device of the type (B) in the region of the corner impact edge 29 is connected to the bottom of the bag on the outer side of the bag and edge 30, also on the outer side of the bag, connected to the tabs, preferably glued.

In einer Alternative wird der entlang der Faltung 28 gefaltete Zettel senkrecht dazu entlang den Linien 36 und 37 gefaltet. Der Abstand zwischen den Faltungen 36 und 37 entspricht der Breite des Bodeneinschlags. Zwischen dem Rand 31 und 32 und der Faltung 36 erfolgt die Verbindung der beiden Flächen. Ebenso auf der gegenüberliegenden Seite zwischen Faltung 37 und Ränder 33 und 34. Die Öffnung 35 liegt somit zwischen den beiden Faltungen 36 und 37, die so die Seitenränder der Tasche darstellen. Die gefalteten Flächen zwischen der Faltung 36 und den Rändern 31 und 32 sowie zwischen Faltung 37 und Ränder 33 und 34 werden mit den Laschen verbunden.In an alternative, the folded along the fold 28 pieces of paper are folded perpendicular thereto along the lines 36 and 37. The distance between the folds 36 and 37 corresponds to the width of the floor impact. Between the edge 31 and 32 and the folding 36, the connection of the two surfaces takes place. Similarly, on the opposite side between fold 37 and edges 33 and 34. The opening 35 is thus between the two folds 36 and 37, which thus constitute the side edges of the bag. The folded surfaces between the fold 36 and the edges 31 and 32 and between fold 37 and edges 33 and 34 are connected to the tabs.

In einer Alternative erfolgt die Faltung 36 und 37 am Rande der Kanten der Einfüllöffnung 4, bzw. der Einfüllvorrichtung. In diesem Fall erfolgt eine Verbindung, bevorzugt Verklebung des Randes 29 mit dem Bodeneinschlag und des Randes 30 mit der Einfüllform bzw. der Entlüftungsvorrichtung des Typs (A) Die Laschen 11 und 12 können auch mit einem zusätzlichen Deckblatt 24 versehen werden. Dieses ist insbesondere am Rand mit allen darunter liegenden teilen verbunden mit Ausnahme einer Längsseite 25, bei der lediglich eine punktuelle Fixierung erfolgt und einer Querseite 26, bei der keine Fixierung erfolgt.In an alternative, the folding 36 and 37 takes place at the edge of the edges of the filling opening 4, or the filling device. In this case, a connection, preferably bonding of the edge 29 with the bottom flap and the edge 30 with the filling or the venting device of the type (A) The tabs 11 and 12 can also be provided with an additional cover sheet 24. This is in particular at the edge with all underlying parts connected with the exception of a longitudinal side 25, in which only a selective fixation takes place and a transverse side 26, in which no fixing takes place.
