- a valve bag for bulk material such as cement, gypsum, granules, animal feed or the like
- a floor and a floor standing opposite the valve floor Preferably, standing and / or valve bottom are formed in a cross or block bottom folding manner.
- a valve for filling the valve bag is incorporated.
- valve sacks are well known and are used in particular for the packaging and distribution of fine-grained bulk material such as cement, gypsum, granules, animal feed or the like.
- the usual sizes are 5 kilos, 10 kilos or 25 kilos.
- 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. It may also be layers of other materials, such as a plastic film, as in the case of EP 1 858 769 B1 ,
- a valve tube is often used in a corner impact of the valve bottom, through which the bag is filled.
- the valve tube mechanically attached to the filler neck of a bottling plant, and the contents are introduced with an air flow in the bag.
- This requires venting of the bag during and after filling.
- the venting usually takes place through the paper walls of the bag.
- it has proven necessary to ensure good ventilation in the area of the valve bottom.
- it is particularly difficult to close the bag well against a Gugutaustritt and at the same time to provide good ventilation there.
- Known in the prior art solutions have proved to be disadvantageous, inter alia, because of a too large material thickness of the soil structure and / or too high complexity and / or rigidity of the soil structure.
- the invention is therefore based on the object to propose an improved ventilation in the valve base for valve bags, which affects as little as possible other important properties of the soil, in particular his ability to machine and tightness of the contents.
- a vent insert is inserted into the valve bottom, wherein the vent insert is not connected to the valve tube and forms an opening to the second corner of the bottom fold.
- the lack of connection with the valve tube stiffening of the valve bottom is avoided.
- the opening of the vent insert to the second corner of the bottom fold allows venting over this corner impact. Air may pass from the interior of the bag through the vent insert and then flow through the opening over the second corner entry into the exterior space.
- the vent insert is wholly or partly made of an air-permeable material, preferably made of paper. Further advantageously, the venting insert on an air-permeable surface, which faces the bag interior. In this way, it is particularly easy for air to escape from the bag interior through this surface and to continue to flow out into the environment via the opening of the venting insert.
- the air-permeable surface is advantageously an air-permeable paper which simultaneously acts as a filter and also fine-grained or dusty filling material -. As cement - holds back in the bag interior.
- the air permeability can also be ensured by a porous or perforated material, wherein the pore size can be suitably adapted to the intended filling.
- the venting insert is designed as a pocket, which is closed to the interior of the bag and accordingly has only the opening to the outside space in the region of the second corner insert.
- this pocket is spaced from the inside of the bag facing the end of the valve tube.
- a bag-shaped vent insert can be advantageously prepared by a vent sheet inserted into the open valve bottom and closed when laying the soil by suitable bonding to a vent pocket.
- the bonding of the venting pocket is L-shaped, wherein a leg of the L-structure runs along the edge of the venting insert or the venting pocket, which faces the first corner insert or the valve tube or the bag interior.
- the other leg of the L-structure runs on one of the side flaps of the bottom fold along the edge of the side flap.
- the venting insert is designed as extending between the two corner fences of the bottom fold hose, which is also open on the side of the valve.
- this preferred venting insert has two openings, one in the region of the first and another in the region of the second Eckeinschlages the bottom fold.
- this venting insert is designed as a hose closed towards the interior of the bag, which is introduced into the bottom of the valve in such a way that the bottom is well sealed against product discharge.
- the hose has an air-permeable surface facing the interior of the bag, through which air can escape from the interior of the bag into the hose and flow into the outside space via its openings. Through the two openings a particularly good ventilation is achieved. In particular, after removal of the valve from the filler neck of the filling system, air can also escape well via the tube opening facing the first corner impact.
- the vent insert can be advantageously designed as an internal latch, which extends from the middle floor area on the sofalzlinien the bottom fold to the side flaps of the bottom fold.
- the open bottom can be sealed well, or it can be achieved by suitable bonding of the inner bolt that the vent insert is sealed well against the bag interior, so that air only through the air-permeable surfaces of the vent insert emerge from the bag interior and the opening of the Venting can flow into the outside space, while contents are reliably retained in the bag.
- the inner bar can also cover the entire open valve bottom, and / or form a vent hose according to claim 5 after the laying of the floor and the bonding.
- FIG. 1 shows the valve bag 10 according to the invention with a bottom 20 and an upper part 30, wherein in the upper part 30, the valve 50 is accommodated for filling the valve bag, which is why the bottom 20 is also referred to as floor 20, and the upper part 30 as a valve bottom 30.

Description
Die Erfindung betrifft einen Ventilsack für Schüttgut wie Zement, Gips, Granulat, Tierfutter oder Ähnliches, mit einem Standboden und einem dem Standboden gegenüberliegenden 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 or the like, with a floor and a floor standing opposite the valve floor. 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 insbesondere für die Verpackung und den Vertrieb von feinkörnigem Schüttgut wie Zement, Gips, Granulat, Tierfutter oder Ähnliches eingesetzt. Die üblichen Größen sind dabei 5 Kilo, 10 Kilo oder 25 Kilo. 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
Als Ventil ist in einem Eckeinschlag des Ventilbodens häufig ein Ventilschlauch eingesetzt, durch welchen der Sack befüllt wird. Zum Befüllen wird der Ventilschlauch maschinell auf den Füllstutzen einer Abfüllanlage aufgesteckt, und das Füllgut wird mit einem Luftstrom in den Sack eingebracht. Dies erfordert eine Entlüftung des Sackes während und nach der Befüllung. Bei geeignet ausgebildeten Papiersäcken erfolgt die Entlüftung üblicher Weise durch die Papierwandungen des Sackes. Bei einigen Sackkonstruktionen bzw. Anwendungen hat es sich jedoch als erforderlich erwiesen, für eine gute Entlüftung auch im Bereich des Ventilbodens zu sorgen. Im Bereich des Ventilbodens bereitet es allerdings besondere Schwierigkeiten, den Sack einerseits gut gegen einen Füllgutaustritt zu verschließen und dort gleichzeitig eine gute Entlüftung bereitzustellen. Im Stand der Technik bekannte Lösungen haben sich als nachteilig erwiesen, unter anderem wegen einer zu großen Materialstärke des Bodenaufbaus und/oder zu hoher Komplexität und/oder Steifigkeit der Bodenstruktur.As a valve, a valve tube is often used in a corner impact of the valve bottom, through which the bag is filled. For filling the valve tube mechanically attached to the filler neck of a bottling plant, and the contents are introduced with an air flow in the bag. This requires venting of the bag during and after filling. In suitably trained paper bags, the venting usually takes place through the paper walls of the bag. In some bag designs or applications, however, it has proven necessary to ensure good ventilation in the area of the valve bottom. In the area of the valve bottom, however, it is particularly difficult to close the bag well against a Füllgutaustritt and at the same time to provide good ventilation there. Known in the prior art solutions have proved to be disadvantageous, inter alia, because of a too large material thickness of the soil structure and / or too high complexity and / or rigidity of the soil structure.
Der Erfindung liegt daher die Aufgabe zugrunde, für Ventilsäcke eine verbesserte Entlüftung im Bereich des Ventilbodens vorzuschlagen, welche andere wichtige Eigenschaften des Bodens, insbesondere seine Maschinengänigkeit und Dichtigkeit für das Füllgut, möglichst wenig beeinträchtigt.The invention is therefore based on the object to propose an improved ventilation in the valve base for valve bags, which affects as little as possible other important properties of the soil, in particular his ability to machine and tightness of the contents.
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 vorgesehen, dass in den Ventilboden zusätzlich zum Ventilschlauch ein Entlüftungseinsatz eingesetzt ist, wobei der Entlüftungseinsatz nicht mit dem Ventilschlauch verbunden ist und eine Öffnung zum zweiten Eckeinschlag der Bodenfaltung ausbildet. Durch die fehlende Verbindung mit dem Ventilschlauch wird eine Versteifung des Ventilbodens vermieden. Die Öffnung des Entlüftungseinsatzes zum zweiten Eckeinschlag der Bodenfaltung ermöglicht eine Entlüftung über diesen Eckeinschlag. Luft kann vom Sackinneren durch den Entlüftungseinsatz hindurchtreten und dann durch die Öffnung über den zweiten Eckeinschlag in den Außenraum strömen.According to the invention it is provided that in addition to the valve tube a vent insert is inserted into the valve bottom, wherein the vent insert is not connected to the valve tube and forms an opening to the second corner of the bottom fold. The lack of connection with the valve tube stiffening of the valve bottom is avoided. The opening of the vent insert to the second corner of the bottom fold allows venting over this corner impact. Air may pass from the interior of the bag through the vent insert and then flow through the opening over the second corner entry into the exterior space.
Vorteilhafter Weise ist der Entlüftungseinsatz ganz oder teilweise aus einem luftdurchlässigen Material, vorzugsweise aus Papier, gebildet. Weiter vorteilhaft weist der Entlüftungseinsatz eine luftdurchlässige Fläche auf, die dem Sackinneren zugewandt ist. So kann durch diese Fläche Luft besonders einfach aus dem Sackinneren entweichen und weiter über die Öffnung des Entlüftungseinsatzes in die Umgebung abströmen. Dabei ist die luftdurchlässige Fläche vorteilhafter Weise ein luftdurchlässiges Papier, welches gleichzeitig als Filter wirkt und auch feinkörniges bzw. staubförmiges Füllgut - z. B. Zement - im Sackinneren zurückhält. Die Luftdurchlässigkeit kann auch durch ein poriges bzw. perforiertes Material gewährleistet werden, wobei die Porengröße geeignet an das vorgesehene Füllgut angepasst werden kann.Advantageously, the vent insert is wholly or partly made of an air-permeable material, preferably made of paper. Further advantageously, the venting insert on an air-permeable surface, which faces the bag interior. In this way, it is particularly easy for air to escape from the bag interior through this surface and to continue to flow out into the environment via the opening of the venting insert. The air-permeable surface is advantageously an air-permeable paper which simultaneously acts as a filter and also fine-grained or dusty filling material -. As cement - holds back in the bag interior. The air permeability can also be ensured by a porous or perforated material, wherein the pore size can be suitably adapted to the intended filling.
Bevorzugt ist der Entlüftungseinsatz als Tasche ausgebildet, die zum Sackinneren hin geschlossen ist und dementsprechend nur die Öffnung zum Außenraum im Bereich des zweiten Eckeinschlages aufweist. Vorteilhafter Weise ist diese Tasche von dem dem Sackinneren zugewandten Ende des Ventilschlauches beabstandet. Dadurch wird eine zu hohe Steifigkeit des Bodens vermieden. Ein taschenförmiger Entlüftungseinsatz kann vorteilhaft hergestellt werden, indem ein Entlüftungsblatt in den offenen Ventilboden eingelegt und beim Zulegen des Bodens durch geeignete Verklebung zu einer Entlüftungstasche geschlossen wird. Besonders vorteilhaft ist die Verklebung der Entlüftungstasche L-förmig ausgebildet, wobei ein Schenkel der L-Struktur entlang des Randes des Entlüftungseinsatzes bzw. der Entlüftungstasche verläuft, welcher dem ersten Eckeinschlag bzw. dem Ventilschlauch bzw. dem Sackinneren zugewandt ist. Weiter vorteilhaft verläuft der andere Schenkel der L-Struktur auf einer der Seitenklappen der Bodenfaltung entlang des Randes der Seitenklappe. Mit einer derartigen Ausgestaltung der Klebekontur kann einerseits ein guter Verschluss der Entlüftungstasche erreicht werden, und andererseits eine vergleichsweise große Entlüftungsfläche, die frei von Klebstoff ist und dementsprechend einen signifikanten Beitrag zur Entlüftung leisten kann.Preferably, the venting insert is designed as a pocket, which is closed to the interior of the bag and accordingly has only the opening to the outside space in the region of the second corner insert. Advantageously, this pocket is spaced from the inside of the bag facing the end of the valve tube. As a result, an excessive rigidity of the soil is avoided. A bag-shaped vent insert can be advantageously prepared by a vent sheet inserted into the open valve bottom and closed when laying the soil by suitable bonding to a vent pocket. Particularly advantageously, the bonding of the venting pocket is L-shaped, wherein a leg of the L-structure runs along the edge of the venting insert or the venting pocket, which faces the first corner insert or the valve tube or the bag interior. Further advantageously, the other leg of the L-structure runs on one of the side flaps of the bottom fold along the edge of the side flap. With such an embodiment of the adhesive contour, on the one hand a good closure of the venting pocket can be achieved, and on the other hand a comparatively large venting area which is free of adhesive and can accordingly make a significant contribution to the venting.
In einer anderen bevorzugten Ausgestaltung ist der Entlüftungseinsatz als zwischen den beiden Eckeinschlägen der Bodenfaltung verlaufender Schlauch ausgebildet, der auch auf der Seite des Ventils offen ist. Damit hat dieser bevorzugte Entlüftungseinsatz zwei Öffnungen, eine im Bereich des ersten und eine weitere im Bereich des zweiten Eckeinschlages der Bodenfaltung. Vorteilhafter Weise ist dieser Entlüftungseinsatz als zum Sackinneren hin geschlossener Schlauch ausgebildet, welcher derart in den Ventilboden eingebracht wird, dass der Boden gut gegen Füllgutaustritt abgedichtet ist. Vorteilhaft weist der Schlauch eine dem Sackinneren zugewandte luftdurchlässige Fläche auf, durch die Luft aus dem Sackinneren in den Schlauch entweichen und über dessen Öffnungen in den Außenraum strömen kann. Durch die beiden Öffnungen wird eine besonders gute Entlüftung erzielt. Insbesondere kann nach dem Abziehen des Ventils vom Füllstutzen der Abfüllanlage Luft auch gut über die dem ersten Eckeinschlag zugewandte Schlauchöffnung entweichen.In another preferred embodiment, the venting insert is designed as extending between the two corner fences of the bottom fold hose, which is also open on the side of the valve. Thus, this preferred venting insert has two openings, one in the region of the first and another in the region of the second Eckeinschlages the bottom fold. Advantageously, this venting insert is designed as a hose closed towards the interior of the bag, which is introduced into the bottom of the valve in such a way that the bottom is well sealed against product discharge. Advantageously, the hose has an air-permeable surface facing the interior of the bag, through which air can escape from the interior of the bag into the hose and flow into the outside space via its openings. Through the two openings a particularly good ventilation is achieved. In particular, after removal of the valve from the filler neck of the filling system, air can also escape well via the tube opening facing the first corner impact.
Der Entlüftungseinsatz kann vorteilhaft als Innenriegel ausgebildet sein, der vom mittleren Bodenbereich über die Seitenfalzlinien der Bodenfaltung bis auf die Seitenklappen der Bodenfaltung reicht. Dadurch kann der offene Boden gut abgedichtet werden, bzw. es kann durch geeignete Verklebung des Innenriegels erreicht werden, dass der Entlüftungseinsatz gut gegenüber dem Sackinneren abgedichtet ist, so dass Luft nur durch die luftdurchlässigen Flächen des Entlüftungseinsatzes aus dem Sackinneren austreten und über die Öffnung des Entlüftungseinsatzes in den Außenraum abströmen kann, während Füllgut zuverlässig im Sack zurückgehalten wird.The vent insert can be advantageously designed as an internal latch, which extends from the middle floor area on the Seitenfalzlinien the bottom fold to the side flaps of the bottom fold. Thereby, the open bottom can be sealed well, or it can be achieved by suitable bonding of the inner bolt that the vent insert is sealed well against the bag interior, so that air only through the air-permeable surfaces of the vent insert emerge from the bag interior and the opening of the Venting can flow into the outside space, while contents are reliably retained in the bag.
Besonders bevorzugt kann der Innenriegel auch den gesamten offenen Ventilboden abdecken, und/oder nach dem Zulegen des Bodens und dem Verkleben einen Entlüftungsschlauch im Sinne des Anspruchs 5 bilden.Particularly preferably, the inner bar can also cover the entire open valve bottom, and / or form a vent hose according to claim 5 after the laying of the floor and the bonding.
