Description

Die Erfindung betrifft einen Ventilsack für Schüttgut wie Zement, Gips, Granulat, Tierfutter o. Ä., mit einem Standboden und einem dem Standboden gegenüber liegenden Ventilboden. Vorzugsweise sind Stand- und/oder Ventilboden in Kreuz- oder Blockbodenfaltweise gebildet. In den Ventilboden ist ein Ventil zum Befüllen des Ventilsacks eingearbeitet.The invention relates to a valve bag for bulk material such as cement, gypsum, granules, animal feed o. Ä., With a floor and a floor standing opposite the bottom of the valve. Preferably, standing and / or valve bottom are formed in a cross or block bottom folding manner. In the valve bottom, a valve for filling the valve bag is incorporated.

Derartige Ventilsäcke sind allgemein bekannt und werden im Handel verbreitet für feinkörniges Schüttgut wie Zement, Gips, Granulat, Tierfutter o. Ä. eingesetzt. Die üblichen Größen sind dabei 5kg, 10kg oder 25kg. Derartige Ventilsäcke sind meist aus Papier gefertigt, wobei sie eine oder mehrere Papierlagen aufweisen können, die auch aus einem Papierverbund und/oder beschichtetem Papier bestehen können. Es können auch Lagen aus anderen Materialien vorhanden sein, so z. B. eine Kunststofffolie, wie im Fall der EP 1 858 769 B1 .Such valve bags are well known and are widely used for fine-grained bulk materials such as cement, gypsum, granules, animal feed o. Ä. used. The usual sizes are 5kg, 10kg or 25kg. Such valve sacks are usually made of paper, wherein they may have one or more paper layers, which may also consist of a paper composite and / or coated paper. There may also be layers of other materials, such. As a plastic film, as in the case of EP 1 858 769 B1 ,

In den Ventilboden ist ein Ventilschlauch eingesetzt, durch den der Sack befüllt wird. Nachteilig ist jedoch, dass der Ventilschlauch nach dem Befüllen eine Undichtigkeit darstellt. Im Stand der Technik ist daher bekannt, den Ventilschlauch als sog. Thermoventil auszubilden, welches nach dem Befüllen zugeschweißt werden kann, so wie beispielsweise in der DE 20 2013 005 898 beschrieben. Der Einsatz des schweißbaren Thermomaterials ist jedoch herstellungstechnisch aufwendig und kostenintensiv.In the valve bottom, a valve tube is inserted, through which the bag is filled. The disadvantage, however, is that the valve tube is a leak after filling. In the prior art is therefore known, the valve tube as so-called. Thermoventil form, which can be welded after filling, such as in the DE 20 2013 005 898 described. However, the use of the heatable thermomaterial is manufacturing technically complex and costly.

Aus der DE754505 ist ein Ventilsack mit einem Ventilkanal bekannt, der nach dem Befüllen des Sackes um 180° umgeschlagen wird. Der Umschlag wird dann durch einen Metallstreifen in der umgeschlagenen Position fixiert.From the DE754505 is a valve bag with a valve channel known, which is turned over after filling the bag by 180 °. The envelope is then fixed by a metal strip in the folded position.

Die DE 842 586 stellt den nächstkommenden Stand der Technik für den Gegenstand des Anspruchs 1 dar und offenbart, dass zum Umklappen des Ventilschlauchs nach Abziehen des Einfüllstutzens zusätzliche elastische Mittel vorgesehen sind.The DE 842 586 represents the closest prior art for the subject matter of claim 1 and discloses that additional elastic means are provided for folding the valve tube after removing the filler neck.

Der Erfindung liegt daher die Aufgabe zugrunde, für Ventilsäcke ein verbessertes Ventil vorzuschlagen, welches eine gute Abdichtung bietet sowie einfach und kostengünstig realisiert werden kann.The invention is therefore based on the object to propose an improved valve for valve bags, which offers a good seal and can be realized easily and inexpensively.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Ventilsack mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by a valve bag having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

Erfindungsgemäß ist der Ventilschlauch an seinem zum Sackinneren gewandten Ende mit einem Umschlag versehen, der für eine verbesserte Ventildichtigkeit sorgt. Aufgrund des Umschlages ist der Ventilschlauch im Ausgangszustand abgeknickt und dadurch geschlossen. Wenn der Ventilschlauch zum Befüllen des Sackes auf den Füllstutzen einer Befüllungsanlage aufgesteckt wird, wird der Umschlag vom Füllstutzen aufgespreizt bzw. durchstoßen, so dass sich das innere Ende des Ventilschlauchs öffnet und Füllgut ungehindert passieren kann. Wenn der Ventilschlauch wieder vom Füllstutzen abgezogen wird, klappt der Umschlag aufgrund der Materialspannung des Ventilschlauchmaterials im Umschlagsbereich wieder zu. Dadurch ist der Ventilschlauch wieder in seiner Ausgangsposition, also am inneren Ende umgeschlagen bzw. in Durchlassrichtung wieder abgeknickt, so dass ein Füllgutaustritt durch den Ventilschlauch wirksam verhindert wird.According to the invention, the valve tube is provided at its end facing the interior of the bag with an envelope, which ensures an improved valve tightness. Due to the envelope of the valve tube is bent in the initial state and thus closed. If the valve tube is plugged to fill the bag on the filler neck of a filling system, the envelope of the filler neck is spread or pierced, so that the inner end of the valve tube opens and contents can pass unhindered. When the valve tube is removed again from the filler neck, the envelope folds up again due to the material tension of the valve tube material in the envelope area. As a result, the valve tube is again in its initial position, that is, turned over at the inner end or bent back in the passage direction, so that a Füllgutaustritt is effectively prevented by the valve tube.

So wird erfindungsgemäß eine verbesserte Abdichtung des Ventils bzw. Ventilschlauchs erreicht.Thus, an improved sealing of the valve or valve tube is achieved according to the invention.

Bevorzugt ist vorgesehen, dass der Ventilschlauch aus einem folienartigen Material, vorzugsweise einer Kunststofffolie und weiter vorzugsweise einer PE-Folie gebildet ist. Folienartige Materialien, insbesondere Kunststoff- oder PE-Folien haben für die Funktionalität der Erfindung besonders geeignete Materialeigenschaften. Diese Materialien bilden nämlich bei der Aufspreizung des Umschlages durch den Abfüllstutzen eine besonders geeignete Materialspannung aus, insbesondere in den Seitenbereichen des Umschlages, die dafür sorgt, dass der Umschlag beim Abziehen des Ventilschlauches vom Füllstutzen besonders gut bzw. sicher wieder zuklappt, also wieder in seiner abgeknickte und das Ventil abdichtende Ausgangsposition zurück gelangt. Grundsätzlich ist die Bildung des Ventilschlauches aus beliebigen anderen Materialien oder Materialkombinationen denkbar, so lange diese ermöglichen, dass der Umschlag nach dem Abziehen vom Füllstutzen einer Befüllungsanlage erfindungsgemäß zuklappt und das Ventil abdichtet.It is preferably provided that the valve tube is formed from a film-like material, preferably a plastic film and more preferably a PE film. Foil-like materials, in particular plastic or PE films have for the functionality of the invention particularly suitable material properties. These materials form namely during the spreading of the envelope through the filler neck from a particularly suitable material tension, especially in the side regions of the envelope, which ensures that the envelope when removing the valve tube from the filler particularly good or safely closed again, so again in his kinked and the valve sealing home position comes back. In principle, the formation of the valve tube from any other materials or combinations of materials is conceivable, as long as they allow the envelope closes according to the invention after removal from the filler neck of a filling system and seals the valve.

Geeigneter Weise wird der Ventilschlauch bei der Sackherstellung in den noch offenen Ventilboden eingelegt, d. h. bevor die Seitenklappen des Bodens im Bodenleger einer typischen Sackherstellungsmaschine um die Seitenfalzlinien des Bodens zugeklappt bzw. zugefaltet werden.Suitably, the valve tube is inserted in the bag production in the open valve bottom, d. H. before the side flaps of the bottom in the bottom layer of a typical sack making machine are folded around the side seaming lines of the bottom.

Bevorzugt kann der erfindungsgemäße Umschlag zur Sackaußenseite umgeschlagen sein. Dann liegt das umgeschlagene Ende bei Betrachtung des offenen Ventilbodens oben auf dem übrigen Ventilschlauch, und nach dem Zuklappen der Seitenklappen liegt das umgeschlagene Ende des Ventilschlauchs dann zwischen dem übrigen Ventilschlauch und den zugelegten Seitenklappen. Alternativ kann der Umschlag zum Sackinneren bzw. zum Sackkorpus hin umgeschlagen sein. Dann liegt der Umschlag bei Betrachtung des offenen Ventilbodens unterhalb des übrigen Ventilschlauches. Der Umschlag ist dann dem Sackinnenraum zugewandt. Der nach unten umgeschlagene Umschlag erlaubt eine leichtere Befüllung des Sackes, während der nach oben umgeschlagene Umschlag eine noch etwas bessere Abdichtung ermöglicht.Preferably, the envelope according to the invention can be turned over to the bag outside. Then, the folded end is on top of the rest of the valve tube when looking at the open valve bottom, and after the side flaps are closed, the folded end of the valve tube then lies between the remaining valve tube and the side flaps. Alternatively, the envelope can be turned over to the interior of the bag or to the bag body. Then, the envelope is under consideration of the open valve bottom below the remaining valve tube. The envelope is then facing the bag interior. The folded down envelope allows easier filling of the bag, while the turned-up envelope allows for even better sealing.

In einer bevorzugten Ausgestaltung ist der Ventilschlauch bezogen auf die Seitenfalzlinien des Ventilbodens mittig in den Ventilboden eingelegt bzw. eingeklebt. Dies erleichtert das Aufstecken auf einen Füllstutzen und erlaubt eine bessere Kräfteverteilung bei der mechanischen Beanspruchung während des Füllvorgangs.In a preferred embodiment, the valve tube is inserted or glued centrally in the bottom of the valve relative to the side fold lines of the valve bottom. This facilitates the attachment to a filler neck and allows a better distribution of forces in the mechanical stress during the filling process.

In einer weiter bevorzugten Ausgestaltung ist ein Trägermaterial an den Ventilschlauch angelegt bzw. angeklebt. Dadurch wird der Ventilschlauch verstärkt, so dass er den mechanischen Beanspruchungen während des Füllvorgangs besser Stand halten kann. Durch das Trägermaterial kann dem Ventil auch eine größere Steifigkeit verliehen werden, die ein problemloseres Aufstecken des Ventilsackes auf den Stutzen der Befüllungsanlage begünstigt. Vorteilhafter Weise ist das Trägermaterial mittig in Bezug auf die Seitenfalzlinien des Ventilbodens angebracht. Eine besonders einfacher und vorteilhafter Ventilaufbau ergibt sich, wenn sowohl der Ventilschlauch als auch das Trägermaterial mittig in Bezug auf die Seitenfalzlinie des Ventilbodens angebracht sind.In a further preferred embodiment, a carrier material is applied or glued to the valve tube. As a result, the valve tube is reinforced so that it can better withstand the mechanical stresses during the filling process. By the carrier material, the valve can also be given a greater rigidity, which favors a problem-free attachment of the valve bag to the nozzle of the filling system. Advantageously, the carrier material is mounted centrally with respect to the Seitenfalzlinien the valve bottom. A particularly simple and advantageous valve construction results when both the valve tube and the carrier material are mounted centrally with respect to the Seitenfalzlinie the valve bottom.

Das Trägermaterial kann bezogen auf den Umfang des Ventilschlauchs vorzugsweise an der zum Sackäußeren und/oder an der zum Sackinneren gewandten Seite des Ventilschlauchs angebracht sein. Bei einer zum Sackäußeren gewandten Anbringung kommt das Trägermaterial demnach zwischen den Ventilschlauch und den zugelegten Seitenklappen des Bodens zu liegen. Bei einem zum Sackinneren gewandten Anbringung liegt das Trägermaterial dagegen beim noch offenen Sackboden unter dem Ventilschlauch und ist damit bei geschlossenem Boden dem Sackinneren bzw. dem Sackkorpus zugewandt.The carrier material may preferably be mounted on the side of the valve tube facing the exterior of the bag and / or on the inside of the bag relative to the circumference of the valve tube. With an attachment facing the exterior of the bag, the carrier material therefore comes to rest between the valve tube and the attached side flaps of the bottom. In a facing the sack interior mounting the carrier material, however, the open bottom of the bag under the valve tube and is thus facing the bag interior and the bag body with the bottom closed.

Weiter vorteilhaft kann das Trägermaterial ebenfalls einen Umschlag aufweisen. Dadurch kann der Zuklappmechanismus nach dem Abziehen vom Füllstutzen begünstigt werden. Besonders vorteilhaft ist es, wenn das Trägermaterial einen dem Ventilschlauch entsprechenden Umschlag aufweist.Further advantageously, the carrier material may also have an envelope. As a result, the Zuklappmechanismus be favored after removal from the filler neck. It is particularly advantageous if the carrier material has an envelope corresponding to the valve tube.

Bevorzugt ist das Trägermaterial aus einem papierartigen Material, vorzugsweise aus Papier oder beschichtetem Papier gebildet, aber auch die Verwendung eines Trägermaterials aus folienartigen Materialien, z. B. einer Kunststoff- oder einer Metallfolie, ist denkbar.Preferably, the carrier material of a paper-like material, preferably formed from paper or coated paper, but also the use of a carrier material of sheet-like materials, for. As a plastic or a metal foil, is conceivable.

Weiter vorteilhaft haben Ventilschlauch oder Trägermaterial in achsialer Richtung des Ventilschlauches die gleiche Länge.Advantageously, valve tube or carrier material in the axial direction of the valve tube have the same length.

Besonders bevorzugt deckt das Trägermaterial den Umfang des Ventilschlauchs hälftig ab. Dabei kann vorzugsweise die zum Sackäußeren oder die zum Sackinneren gewandte Hälfte des Ventilschlauches abgedeckt sein.Particularly preferably, the carrier material covers the circumference of the valve tube in half. In this case, preferably, the half of the valve tube facing the exterior of the bag or the interior of the bag can be covered.

In einer anderen bevorzugten Ausgestaltung umschließt das Trägermaterial den Ventilschlauch nach Art eines Schlauches. Dann ist der Ventilschlauch von einem Trägermaterialschlauch umgeben, wodurch eine besondere mechanische Verstärkung erreicht wird.In another preferred embodiment, the carrier material surrounds the valve tube in the manner of a hose. Then the valve tube is surrounded by a carrier material tube, whereby a special mechanical reinforcement is achieved.

In einer anderen bevorzugten Ausgestaltung ist das Trägermaterial an den Ventilschlauch an dessen nach außen gewandter Seite angebracht und bildet gleichzeitig einen sogenannten Innenriegel. Als Innenriegel wird üblicher Weise eine zusätzliche Abdeckung des noch aufgeklappten Ventilbodens verstanden, die den offenen Ventilboden verschließt und dadurch für zusätzliche Dichtigkeit sorgt.In another preferred embodiment, the carrier material is attached to the valve tube on its outwardly facing side and at the same time forms a so-called inner bar. As an internal latch is usually understood an additional cover of the still unfolded valve bottom, which closes the open valve bottom and thereby provides additional tightness.

The number or type of paper or material layers used concretely is irrelevant to the embodiment of the invention, which is why it will not be discussed in more detail.

Figur 2 zeigt den aufgeklappten Ventilboden 30 des Ventilsackes gemäß dem ersten Ausführungsbeispiel, wobei das Ventil durch den in Figur 3 separat gezeigten Ventilschlauch 50 gebildet ist. Figur 3 zeigt den Ventilschlauch 50 in seiner Ausgangsposition (Ventil geschlossen). Der Ventilschlauch weist einen Umschlag 52 mit der Länge X auf, der in Figur 2 schraffiert dargestellt ist. Durch den Umschlag 52 ist der Ventilschlauch abgeknickt und für den Durchtritt Füllgut gesperrt. Wie in Figur 3 gezeigt, verläuft der Umschlag bzw. die durch den Umschlag gebildete Knicklinie 56 vorteilhafter Weise mehr oder weniger quer zur achsialen Richtung des Schlauches. Jedoch ist auch ein Verlauf schräg zur achsialen Richtung des Schlauches möglich, solange nur der gesamte Schlauchquerschnitt durch den Knick 56 verschlossen bzw. gesperrt wird. Die Länge X des Umschlages 52 kann in geeigneter Weise variieren. FIG. 2 shows the unfolded valve bottom 30 of the valve bag according to the first embodiment, wherein the valve by the in FIG. 3 separately shown valve hose 50 is formed. FIG. 3 shows the valve tube 50 in its initial position (valve closed). The valve tube has an envelope 52 of length X, which in FIG. 2 hatched. By the envelope 52 of the valve tube is bent and locked for the passage of filling. As in FIG. 3 shown, the envelope or the bend line formed by the envelope 56 advantageously extends more or less transversely to the axial direction of the tube. However, a course obliquely to the axial direction of the tube is possible, as long as only the entire tube cross-section is closed or blocked by the kink 56. The length X of the envelope 52 may vary as appropriate.

Gemäß dem Ausführungsbeispiel ist der Ventilschlauch 50 als PE-Schlauch ausgebildet und wird, wie in Figur 2 ersichtlich, bei der Sackherstellung mit dem Umschlag 52 in den offenen Sackboden 30 eingelegt und eingeklebt bzw. dort befestigt. Der Umschlag 52 kann wie in Figur 3 gezeigt nach oben umgeschlagen sein, alternativ aber auch nach unten. Der Umschlag kommt dann nach Einlegung des Ventils in den aufgeklappten Ventilboden entweder auf der zum Sackäußeren oder zum Sackinneren gewandten Seite des übrigen Ventilschlauchs 50 zu liegen.According to the embodiment, the valve tube 50 is formed as a PE tube and is, as in FIG. 2 can be seen in the bag production with the envelope 52 inserted into the open bag bottom 30 and glued or fixed there. The envelope 52 may, as in FIG. 3 shown turned up, but alternatively also down. The envelope then comes after placement of the valve in the unfolded valve bottom either on the side facing the bag exterior or the bag interior side of the remaining valve tube 50 to lie.

Wie in Figur 2 weiter gezeigt ist der Ventilschlauch 50, dessen Umrisse in Figur 2 mit gestrichelten Linien dargestellt sind, bezogen auf die Seitenfalzlinien 32, 33 des Ventilbodens 30 mittig in den Ventilboden 30 eingelegt. Des Weiteren ist über den Ventilschlauch ein Trägermaterial 54 gelegt, und zwar ebenfalls mittig in Bezug auf die Seitenfalzlinien 32, 33 des Ventilbodens 30. In Figur 2 ist das Trägermaterial 54 demnach an den zum Sackäußeren gewandten Seite des Ventilschlauchs 50 an diesen angelegt, wobei das Trägermaterial und der umgeschlagene Ventilschlauch 50 in achsialer Richtung des Ventilschlauchs die gleiche Länge haben. In der Querrichtung übersteigt die Breite des Trägermaterials 54.die des Ventilschlauchs 50, so dass das Trägermaterial über die Seitenfalzlinie 32, 33 hinaus weiter in die Seitenklappen des Bodens hineinreicht.As in FIG. 2 further shown is the valve tube 50, whose outlines in FIG. 2 are shown with dashed lines, based on the Seitenfalzlinien 32, 33 of the valve bottom 30 inserted centrally into the valve bottom 30. Furthermore, a carrier material 54 is placed over the valve tube, and also centrally with respect to the Seitenfalzlinien 32, 33 of the valve bottom 30. In FIG. 2 Accordingly, the carrier material 54 is applied to the side facing the bag exterior of the valve tube 50 to the latter, wherein the carrier material and the folded valve tube 50 in the axial direction of the valve tube have the same length. In the transverse direction, the width of the substrate 54 exceeds that of the valve tube 50 such that the substrate extends beyond the side fold line 32, 33 farther into the side flaps of the floor.

In Figur 2 ist der Umfang des Ventilschlauchs hälftig vom Trägermaterial 54 abgedeckt, nämlich auf der zum Sackäußeren gewandten Halbseite des Umfangs.In FIG. 2 the circumference of the valve tube is covered in half by the carrier material 54, namely on the half of the circumference facing the outer side of the bag.

Figur 4 zeigt ein Ausführungsbeispiel, bei dem das Trägermaterial 54 nach Art eines Schlauches um den Ventilschlauch 50 gelegt wird. In Figur 4 ist auf den noch aufgeklappten Ventilboden 30 im Bereich des linken Eckeinschlags das Trägermaterial 54 auf den Ventilboden 30 aufgelegt. Auf das Trägermaterial 54 ist wiederum der Ventilschlauch 50 aufgebracht, so dass das Trägermaterial 54 zwischen dem Ventilschlauch und dem offenen Ventilboden zu liegen kommt. Trägermaterial 54 und umgeschlagener Ventilschlauch 50 haben in der Durchlassrichtung des Ventils die gleiche Länge. Quer zur Ventildurchlassrichtung ist das Trägermaterial derart breit, dass es beim Zulegen des Bodens um die Seitenfalzlinien 32 und 33 von oben auf den Ventilschlauch gelegt und diesen dann nach Art eines Schlauches umgibt. Diese Ausgestaltung ist besonders vorteilhaft, wenn ein größerer Ventilboden 30 mit einem kleinere Ventilschlauch 50 versehen werden soll, insbesondere mit einem Ventilschlauch 50 der nicht die gesamte Breite zwischen den beiden Seitenfalzlinien 32 und 33 abdeckt. FIG. 4 shows an embodiment in which the carrier material 54 is placed around the valve tube 50 in the manner of a hose. In FIG. 4 is on the still unfolded valve bottom 30 in the region of the left Eckeinschlags the carrier material 54 placed on the valve bottom 30. The valve tube 50 is in turn applied to the carrier material 54 so that the carrier material 54 comes to rest between the valve tube and the open valve bottom. Carrier material 54 and folded valve tube 50 have the same length in the direction of passage of the valve. Transverse to the valve passage direction, the carrier material is so wide that, when laying the bottom around the Seitenfalzlinien 32 and 33 of placed on top of the valve tube and then surrounds it in the manner of a hose. This embodiment is particularly advantageous when a larger valve bottom 30 is to be provided with a smaller valve tube 50, in particular with a valve tube 50 which does not cover the entire width between the two Seitenfalzlinien 32 and 33.

Figur 5 zeigt ein drittes Ausführungsbeispiel, bei dem das Trägermaterial 54 nach Art eines Innenriegels über den Ventilschlauch 50 und den offenen Ventilboden 30 gelegt ist. Bei dieser Ausgestaltung wird bei der Sackherstellung zunächst der Ventilschlauch 50 mit einem nach unten bzw. zum Sackinneren hin umgeschlagenen Umschlag 52 auf den offenen Ventilboden aufgelegt. Dann wird mit dem großformatigen Trägermaterial 54 nach Art eines Innenriegels der aufgeklappte Ventilboden abgedeckt, so dass der Ventilboden bereits durch das Trägermaterial 54 geschlossen ist. Dann werden die Seitenklappen des Ventilbodens in üblicher Weise zugelegt. Bei dieser Ausgestaltung erhält der Ventilboden 30 eine gleichmäßige Steifigkeit über nahezu die gesamte Bodenbreite bzw. -fläche, und der Ventilsack erhält durch den Innenriegel eine zusätzliche Abdichtung. FIG. 5 shows a third embodiment in which the carrier material 54 is placed over the valve tube 50 and the open valve bottom 30 in the manner of an internal bolt. In this embodiment, the valve tube 50 is first placed on the open bottom of the valve in the bag making with a folded down to the bag or inside out envelope 52. Then, the unfolded valve bottom is covered with the large-sized carrier material 54 in the manner of an internal bolt, so that the valve bottom is already closed by the carrier material 54. Then the side flaps of the valve bottom are added in the usual way. In this embodiment, the valve bottom 30 receives a uniform rigidity over almost the entire bottom width or area, and the valve bag is replaced by the inner latch an additional seal.

Mit der Erfindung werden eine Reihe von Vorteilen erzielt. So kann eine deutlich verbesserte Ventildichtigkeit erreicht werden, insbesondere im Vergleich zu vorbekannten Ventilsäcken mit innen liegenden Ventilen ohne Abdichtung. Die erfindungsgemäßen Ventilsäcke können auch in den bekannten und bereits bestehenden Befüllungsanlagen befüllt werden, so dass die Abnehmer bzw. Verwender der Säcke keine neue Anlagentechnik benötigen. Die erfindungsgemäßen Ventilsäcke stellen im Vergleich zu den deutlich teureren Thermoventil-Säcken eine wesentlich günstigere Alternative für ein gut abdichtendes Ventil dar. Außerdem bedürfen die erfindungsgemäßen Ventile anders als die Thermoventile keiner Verschweißung, was die automatische Befüllung der Säcke vereinfacht, da keine Verschweißung mehr erforderlich ist, und die Befüllungsanlagen daher keine Schweißstation benötigen. With the invention a number of advantages are achieved. Thus, a significantly improved valve tightness can be achieved, in particular in comparison to previously known valve bags with internal valves without sealing. The valve sacks according to the invention can also be filled in the known and already existing filling systems, so that the customers or users of the sacks do not need any new system technology. Valve bags according to the invention provide in comparison to the much more expensive thermo valve bags a much cheaper alternative for a good sealing valve. In addition, unlike the thermal valves need no welding, which simplifies the automatic filling of the bags, since no more welding is required , and the filling systems therefore need no welding station.
