Description

Die Erfindung betrifft einen Sack, gemäß dem Oberbegriff des Anspruchs 1, bestehend aus einer zu einem Schlauch verklebten einlagigen oder mehrlagigen Sackwandung, die wenigstens einseitig einen zur Befüllung mit Füllgut durch einen Füllstutzen einer Sackfüllmaschine geeigneten, gefalteten und verklebten, mit einer Ventilöffnung ausgebildeten Boden aufweist und die sich in Wasser auflöst.The invention relates to a bag, according to the preamble of claim 1, consisting of a bonded to a tube single-layer or multilayer bag wall having at least one side suitable for filling with filling material through a filler neck of a bag filling machine, folded and glued, formed with a valve opening bottom and which dissolves in water.

Die Erfindung betrifft insbesondere die Verwendung eines derartigen Sacks als Zementsack, bei dem die Auflösung der Sackwandung in einer Betonmischmaschine mit Wasser und Sand und vorzugsweise Kies als Zugschlagstoff erfolgt.The invention particularly relates to the use of such a bag as a cement bag, in which the dissolution of the bag wall in a concrete mixer with water and sand and preferably gravel takes place as Zugschlagstoff.

Es sind seit langem Säcke bekannt, die mit einem trockenen Füllgut über eine Sackfüllmaschine befüllbar sind. Das Füllgut ist dazu bestimmt, an einem Einsatzort mit feuchten Materialien gemischt zu werden, um so eine aushärtende Masse, beispielsweise Beton, zu erhalten. Hierzu wird der als Ventilsack ausgebildete Sack an seiner Oberseite aufgeschnitten und das trockene und staubende Füllgut in eine Mischvorrichtung geschüttet, in der es zu einer feuchten Mischung verarbeitet wird, die aushärtet, wenn der Mischvorgang abgeschlossen ist. Ein Beispiel für ein derartiges Füllgut ist Zement, der in einer Betonmischmaschine oder Betonmischanlage mit Wasser, Sand und ggf. Kies zu einer erdfeuchten Mörtelmischung verarbeitet wird, die an Ort und Stelle, im Allgemeinen an einem Bauwerk, in eine Schalung gießbar ist und dort aushärtet, um beispielsweise einen Betonträger, eine Betonwand o. dgl. zu bilden.There are long known bags that can be filled with a dry product via a bag filling machine. The contents are intended to be mixed at a place of use with moist materials, so as to obtain a hardening mass, such as concrete. For this purpose, the trained as a valve bag bag is cut at its top and poured the dry and dusty contents in a mixing device in which it is processed into a wet mixture, which hardens when the mixing process is completed. An example of such a product is cement, which is processed in a concrete mixer or concrete mixing plant with water, sand and possibly gravel to a soil-wet mortar mixture, which is pourable in place, generally on a building, in a formwork and cures there For example, to form a concrete beam, a concrete wall o.

Das Einschütten des trockenen und staubigen Füllguts in die Mischvorrichtung ist dabei problematisch, weil ein Teil des Füllguts ausstaubt. Dies ist für die Bedienperson nicht nur wegen der damit verbundenen Verschmutzung unangenehm sondern auch potentiell gesundheitsgefährdend.The pouring of the dry and dusty filling material into the mixing device is problematic because a part of the contents dusted out. This is unpleasant for the operator not only because of the pollution associated with it but also potentially harmful to health.

Es ist daher die Idee entstanden, einen derartigen Sack mit einer sich in feuchter Umgebung auflösenden Sackwandung auszubilden, damit der Sack mit dem Füllgut ungeöffnet in die Mischvorrichtung geworfen werden kann. Nach dem Auflösen der Sackwandung steht das Füllgut als benötigter Zement zur Verfügung, um die Mörtelmischung herzustellen. Sofern sich die Sackwandung, die aus einem wasserlöslichen Papier gebildet ist, vollständig auflöst, ist das (Papier-) Material der Wandung für die Bildung des Betons unschädlich. Bei diesem Verfahren könnte daher das unweigerlich zum Ausstauben von Füllgut führende Öffnen des Sacks und Ausschütten des Füllguts in die Mischvorrichtung vermieden werden.Therefore, the idea has arisen to design such a bag with a bag wall which dissolves in a moist environment, so that the bag with the contents can be thrown unopened into the mixing device. After dissolving the bag wall, the contents are available as required cement to produce the mortar mixture. If the bag wall, which is formed from a water-soluble paper, completely dissolves, the (paper) material of the wall for the formation of the concrete is harmless. In this method, therefore, inevitably leading to the dusting of contents opening the bag and dumping the contents could be avoided in the mixing device.

Es hat sich jedoch gezeigt, dass bei normalen Mischzeiten von wenigen Minuten eine vollständige Auflösung der Sackwandung nicht erreichbar ist, sondern dass Sackwandungsstücke von nicht unerheblicher Größe in der Mischung verbleiben. Dies ist unakzeptabel, da die verbleibenden Stücke aus dem Material der Sackwandung, also insbesondere Papierstücke den stabilen Betonverbund behindern und so Schwachstellen in dem Betonbauteil verursachen. Eine in der Praxis akzeptable Lösung für einen sich in einer feuchten Umgebung innerhalb einer Mischvorrichtung vollständig auflösenden Sack ist daher noch nicht gefunden worden.However, it has been shown that with normal mixing times of a few minutes, a complete dissolution of the bag wall is not achievable, but that Sackwandungsstücke remain of considerable size in the mixture. This is unacceptable because the remaining pieces of the material of the bag wall, so in particular pieces of paper obstruct the stable concrete composite and thus cause weaknesses in the concrete component. A solution acceptable in practice for a completely dissolving sack in a humid environment within a mixing device has therefore not yet been found.

US 2010/0008603 A1 offenbart einen Ventilsack bei dem eine Ventilöffnung durch einen verschließbaren Ventilschlauch gebildet ist. Hierfür wird Heißschmelzkleber verwendet, der die Repulpierbarkeit des Sackmaterials zum Zwecke des Recyclings nicht behindert. Daher wird ein im Wasser dispergierbarer Polyamid-Heißschmelzkleber vorgesehen. US 2010/0008603 A1 discloses a valve bag in which a valve opening is formed by a closable valve tube. For this purpose, hot melt adhesive is used, which does not hinder the repulpability of the bag material for the purpose of recycling. Therefore, a water-dispersible polyamide hot melt adhesive is provided.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Sack der eingangs erwähnten Art so zu erstellen, dass sich unter den üblichen Mischbedingungen und üblichen Mischzeiten, wie sie beispielsweise in einer Betonmischvorrichtung gegeben sind, vollständig auflöst, sodass die hergestellte Betonmischung fehlerfrei ohne störende unaufgelöste Materialreste der Sackwandung herstellbar ist.The present invention has for its object to provide a bag of the type mentioned above, that under the usual mixing conditions and usual mixing times, such as those given in a concrete mixer, completely dissolves, so that the concrete mixture produced without errors without disturbing unresolved material residues Sack wall can be produced.

Zur Lösung dieser Aufgabe ist ein Sack der eingangs erwähnten Art dadurch gekennzeichnet, dass die Verklebung des Bodens mit einem Dextrinkleber erfolgt ist. Insbesondere besteht der Dextrinkleber aus Maltodextrin mit einem Dextroseäquivalent zwischen 4,5 und 8,5.To solve this problem, a bag of the type mentioned is characterized in that the bonding of the soil is done with a dextrin adhesive. In particular, the dextrin glue is maltodextrin with a dextrose equivalent between 4.5 and 8.5.

Zur Befüllung durch eine Sackfüllmaschine geeignete Säcke sind im Allgemeinen mit Kreuzböden abgeschlossen. Als Kreuzboden ist insbesondere der die Ventilöffnung aufweisende Boden ausgebildet. An einem derartigen Boden müssen notgedrungen zahlreiche Lagen der Sackwandung aufeinander gelegt und miteinander verklebt werden. Untersuchungen mit einem fluoreszierenden Klebstoff haben ergeben, dass die nicht aufgelösten Teile der Sackwandung insbesondere solche Teile sind, die mehrere durch Klebstoff miteinander verbundene Lagen aufweisen. Es ist daher von besonderer Bedeutung, einen Klebstoff zu verwenden, der wasserlöslich ist.Sacks suitable for filling by a bag filling machine are generally finished with cross bottoms. As a cross bottom, in particular, the valve opening having the bottom is formed. On such a floor must be forced to put numerous layers of the bag wall each other and glued together. Investigations with a fluorescent adhesive have shown that the unresolved parts of the bag wall are in particular those parts which have a plurality of layers bonded together by adhesive. It is therefore of particular importance to use an adhesive which is water-soluble.

Der erfindungsgemäß angestrebte Erfolg wird jedoch mit üblichen wasserlöslichen Klebern nicht erzielt, da auch weiterhin, beispielsweise in einer Betonmischmaschine, nach einer üblichen maximalen Mischzeit von 5 Minuten keine vollständige Auflösung des Materials der Sackwandung erfolgt.However, the desired success of the invention is not achieved with conventional water-soluble adhesives, as continue, for example, in a concrete mixer, after a usual maximum mixing time of 5 minutes, no complete dissolution of the material of the bag wall.

In überraschender Weise ist gefunden worden, dass eine für die praktischen Anforderungen vollständige Auflösung der Sackwandung erreicht wird, wenn die Verklebung des Bodens mit einem als Lebensmittelkleber verwendeten Dextrinkleber erfolgt, insbesondere mit Maltodextrin mit einem Dextroseäquivalent zwischen 4,5 und 8,5.Surprisingly, it has been found that a complete dissolution of the bag wall is achieved for the practical requirements if the bonding of the bottom takes place with a dextrin glue used as food adhesive, in particular with maltodextrin having a dextrose equivalent between 4.5 and 8.5.

Ein derartiger Dextrinkleber ist für die Verklebung, insbesondere die Bodenverklebung, von Papierlagen eines Sacks noch nicht verwendet worden. Der erfindungsgemäße Kleber hat die Eigenschaft, dass er sich auch in einer erdfeuchten Umgebung sehr schnell auflöst und die aneinander liegenden Lagen der Sackwandung so freigibt, dass diese als Einzellagen einer schnellen Auflösung in einer wenigstens erdfeuchten Umgebung unterliegen.Such a dextrin adhesive has not been used for the bonding, in particular the Bodenverklebung, of paper layers of a bag. The adhesive according to the invention has the property that it dissolves very quickly even in a humid environment and the adjacent layers of the bag wall releases so that they are subject as individual layers of rapid dissolution in an at least humidified environment.

Die erfindungsgemäße Problemlösung sieht somit nicht eine Verbesserung des Materials der Sackwandung vor, sondern durch die Verwendung eines speziellen Klebers, zumindest für die Verklebung des Bodens, eine schnelle Trennung der zum Boden miteinander verklebten Teile der Sackwandung, sodass auch diese Teile, wie die übrige Sackwandung außerhalb des Bodens, einer schnellen und vollständigen Auflösung in der zumindest erdfeuchten Umgebung ausgesetzt sind.The problem solving according to the invention thus does not provide an improvement of the material of the bag wall, but by the use of a special adhesive, at least for the bonding of the soil, a rapid separation of the parts bonded to the ground parts of the bag wall, so that these parts, like the rest of the bag wall outside the ground, are exposed to a rapid and complete dissolution in the at least earth-moist environment.

In einer bevorzugten Ausführungsform der Erfindung gelingt die Auflösung des Sacks auch im Bereich der gefalteten und verklebten Böden besonders gut dadurch, dass die zur Faltung des Bodens aufeinander gelegten Bodenklappen sich nur wenig, vorzugsweise um maximal 2 cm, besonders bevorzugt um maximal 1 cm, überlappen.In a preferred embodiment of the invention, the dissolution of the bag also succeeds particularly well in the area of folded and bonded bottoms in that the bottom flaps superimposed on the folding of the bottom overlap only slightly, preferably by a maximum of 2 cm, particularly preferably by a maximum of 1 cm ,

Besonders gut geeignet ist zur Ausbildung eines Kreuzbodens mit einer Ventilöffnung ein Ventilboden, der gemäß EP 1 914 173 B1 gefaltet ist. Bei diesem Boden überlappen sich die Bodenklappen vorzugsweise um maximal 1 cm, besonders bevorzugt überlappen sich die Bodenklappen gar nicht, sondern schließen unter Ausbildung eines eventuellen schmalen Schlitzes aneinander an. Die Abdichtung des Sacks erfolgt im Bereich der Bodenklappen mit einem aufgeklebten Bodendeckblatt. Die Ventilöffnung, in die die Füllröhre einer Sackfüllmaschine seitlich einfahren kann, wird dabei zwischen den Bodenklappen und dem Bodendeckblatt ausgebildet. Durch das Einfahren der Füllröhre werden die Bodenklappen zum Sackinnern hin gedrückt und geben einen dadurch verbreiterten Schlitz frei, über den das Füllgut durch die Füllröhre in das Sackinnere gefördert wird. Nach der Füllung des Sacks drückt das Füllgut die Bodenklappen wieder gegeneinander bzw. gegen das Bodendeckblatt, wodurch der Sack durch das Gewicht des Füllgutes hinreichend verschlossen ist.Is particularly well suited to form a cross-bottom with a valve opening a valve bottom, according to EP 1 914 173 B1 folded. In this floor, the bottom flaps preferably overlap by a maximum of 1 cm, more preferably, the bottom flaps do not overlap at all, but join together to form a possible narrow slit. The sealing of the bag takes place in the area of the bottom flaps with a glued bottom cover sheet. The valve opening into which the filling tube of a bag filling machine can enter laterally is formed between the bottom flaps and the bottom cover sheet. By retracting the filling tube, the bottom flaps are pressed toward the interior of the bag and release a widened thereby slot, through which the filling material is conveyed through the filling tube into the bag interior. After the filling of the bag, the filling presses the bottom flaps against each other or against the bottom cover sheet, whereby the bag is sufficiently closed by the weight of the contents.

In einer anderen bevorzugten Ausführungsform überlappen sich die Bodenklappen oberhalb eines Eckeinschlags des Bodens um maximal 2 cm, wobei die Ventilöffnung zwischen den Bodenklappen und dem Eckeinschlag ausgebildet wird.In another preferred embodiment, the bottom flaps overlap above a corner impact of the soil by a maximum of 2 cm, wherein the valve opening is formed between the bottom flaps and the corner hinge.

Für die vorliegende Erfindung ist es bevorzugt, die Ventilöffnung ohne ein sonst übliches gefaltetes Ventilblatt auszubilden.For the present invention, it is preferred to form the valve opening without an otherwise conventional folded valve sheet.

Eine Minimierung des Klebstoffauftrags lässt sich bei den erfindungsgemäßen Bodenkonstruktionen dadurch erreichen, dass das Bodendeckblatt eine größere Breite als der gefaltete Boden aufweist und sich wenigstens einseitig über eine lange Bodenfaltlinie auf die benachbarte Sackwand erstreckt. Dadurch wird die Bodenkonstruktion mit geringem Klebstoffaufwand stabilisiert. Die Verklebung des Bodendeckblatts mit der benachbarten Sackwand - vom Boden ausgesehen jenseits der Bodenfaltlinie - führt zu einer Verteilung des Klebstoffauftrags für die Bildung des Bodens auch auf die benachbarte Sackwand, sodass eine für die Auflösung schädliche Klebstoffkonzentration, durch die zunächst mehrere Lagen des Sackes aufeinanderliegen, verringert wird.A minimization of the adhesive application can be achieved in the floor constructions according to the invention in that the bottom cover sheet has a greater width than the folded bottom and extends at least on one side over a long Bodenfaltlinie on the adjacent bag wall. As a result, the floor construction is stabilized with little adhesive effort. The bonding of the bottom cover sheet with the adjacent bag wall - seen from the bottom beyond the bottom fold line - leads to a distribution of the adhesive application for the formation of the soil on the adjacent bag wall, so that a harmful for the dissolution adhesive concentration by the first several layers of the bag on each other, is reduced.

Für das Material der Sackwandung ist es lediglich wichtig, dass es sich in feuchter Umgebung leicht auflöst. Demgemäß kann die Sackwandung aus einer oder mehreren Lagen eines gut wasserlöslichen Papiers bestehen. Dieses Papier ist vorzugsweise nicht geleimt und enthält Stärke nur in geringen Mengen. Darüber hinaus kann die Sackwandung auch eine wasserlösliche Folie enthalten, also aus wenigstens einer Lage Papier und wenigstens einer Lage der wasserlöslichen Folie bestehen. Weiterhin ist es möglich, die Sackwandung ausschließlich aus einer wasserlöslichen Folie zu bilden. In allen Fällen ist es zweckmäßig, wenn für die Bedruckung der Sackwandung auch darauf geachtet wird, dass eine wasserlösliche Farbe benutzt wird, da andernfalls eine nicht wasserlösliche Farbe die Auflösung der Sackwandung in dem mit der Farbe bedruckten Bereich erschweren oder verhindern könnte.For the material of the bag wall, it is only important that it dissolves easily in a humid environment. Accordingly, the bag wall can consist of one or more layers of a readily water-soluble paper. This paper is preferably not sized and contains starch only in small amounts. In addition, the bag wall may also contain a water-soluble film, ie consist of at least one layer of paper and at least one layer of water-soluble film. Furthermore, it is possible to form the bag wall exclusively from a water-soluble film. In all cases, it is expedient if it is also ensured that a water-soluble ink is used for the printing of the bag wall, since otherwise a non-water-soluble ink could complicate or prevent the dissolution of the bag wall in the area printed with the ink.

Der erfindungsgemäße Sack wird bevorzugt als Zementsack verwendet, dessen Sackwandung in einer Betonmischmaschine mit Wasser und Sand als Zuschlagstoff aufgelöst wird. Es hat sich gezeigt, dass die Auflösung der Sackwandung noch dadurch unterstützt wird, dass neben Sand auch Kies als Zuschlagstoff für den Beton verwendet wird. Insbesondere für diesen Anwendungsfall ist eine perfekte Auflösung der Sackwandung und die Herstellung eines fehlerfreien Betonteils erzielbar.The bag of the invention is preferably used as a cement bag, the bag wall is dissolved in a concrete mixer with water and sand as an aggregate. It has been shown that the dissolution of the bag wall is further supported by the fact that, in addition to sand, gravel is also used as an additive for the concrete. In particular, for this application, a perfect resolution of the bag wall and the production of a faultless concrete part can be achieved.

Die Erfindung soll im Folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The invention will be explained in more detail below with reference to an embodiment shown in the drawing.

Die einzige Zeichnungsfigur zeigt eine zu einem Schlauch geklebte Sackwandung, bei der Eckeinschläge zur Bildung von Kreuzböden an beiden Enden des Schlauchs vorgenommen worden sind.The sole drawing figure shows a bag wall glued to a hose, in which corner impacts have been made to form cross bottoms at both ends of the hose.

Die Zeichnung zeigt somit einen flachliegenden Schlauch 1 einer Sackwandung 2, bei der eine untere Lage und eine obere Lage somit aufeinanderliegen. Der aus dem Schlauch 1 hergestellte Sack ist an Ober- und Unterseite mit jeweils einem Boden 3, 4 abgeschlossen. Beide Böden sind als Kreuzböden ausgebildet.The drawing thus shows a flat hose 1 of a bag wall 2, in which a lower layer and an upper layer thus lie on one another. The bag made of the tube 1 is closed at the top and bottom, each with a bottom 3, 4. Both floors are designed as cross floors.

Die Kreuzböden werden in üblicher Weise von Eckeinschlägen 5, 6, die aus einer bloßen Faltung des Schlauchs 1, ausgehend von den Längsseitenkanten, hergestellt werden, ausgebildet. Durch den Eckeinschlag wird die obere Sackwandung 2 um eine mittlere Faltlinie 7 auf sich selbst zurückgefaltet, während die untere Sackwadung 2 sich durch den Eckeinschlag 5, 6 fortsetzt und die andere Hälfte des Bodenmaterials bildet. Zwei parallel zu der Faltlinie 7 verlaufende Faltlinien 8 trennen Bodenklappen 9, 10, die um die Faltlinien 8 gegeneinander klappbar sind. Dabei liegen die Bodenklappen 9, 10 mit den in der Zeichnung schraffierten Bereichen 11 auf dem mittleren Bereich der Eckeinschläge 5, 6auf. Zur Herstellung des Bodens können daher die Bereiche 11 mit einem Klebstoffauftrag versehen sein.The cross floors are formed in the usual way of corner fences 5, 6, which are made of a mere folding of the tube 1, starting from the longitudinal side edges. Due to the corner impact, the upper bag wall 2 is folded back on itself about a middle fold line 7, while the lower bag weight 2 continues through the corner fold 5, 6 and forms the other half of the bottom material. Two fold lines 8 running parallel to the fold line 7 separate bottom flaps 9, 10 which can be folded around the fold lines 8 against each other. In this case, the bottom flaps 9, 10 with the hatched in the drawing areas 11 on the central region of the corner fences 5, 6auf. For the production of the soil, therefore, the regions 11 may be provided with an adhesive application.

An dem in der Zeichnung links dargestellten Boden 4, der als Ventilboden mit einer Ventilöffnung versehen wird, befindet sich an der äußeren Bodenklappe 10 ein außen aufgeklebtes Bodendeckblatt 12, das rechteckig mit einer Länge ausgebildet ist, die der Länge des Bodens des Sacks entspricht, wenn er durch seine Füllung in eine im Wesentlichen rechteckige Quaderform gebracht wird.At the bottom 4 shown in the drawing on the left, which is provided as a valve bottom with a valve opening, located on the outer bottom flap 10 an externally glued bottom cover sheet 12 which is formed rectangular with a length corresponding to the length of the bottom of the bag, if he is brought by its filling in a substantially rectangular parallelepiped shape.

In dem dargestellten Ausführungsbeispiel wird eine Ventilöffnung 13 zwischen dem Eckeinschlag 6 und den Bodenklappen 9, 10 ausgebildet, indem im Bereich der Ventilöffnung 13 auf eine Klebstoffverbindung zwischen dem Eckeinschlag 6 und den beiden Bodenklappen 9, 10 verzichtet wird. Die Verbindung der Bodenklappen 9, 10 wird dabei durch das aufgeklebte Bodendeckblatt 12 sichergestellt.In the illustrated embodiment, a valve opening 13 between the corner wedge 6 and the bottom flaps 9, 10 is formed by an adhesive connection between the corner wedge 6 and the two bottom flaps 9, 10 is dispensed with in the region of the valve opening 13. The connection of the bottom flaps 9, 10 is ensured by the glued ground cover sheet 12.

Das Bodendeckblatt 12 ist über seine Länge, die der Breite des späteren Sacks entspricht, mit einem Streifen 14 versehen, der über die von dem Bodendeckblatt 12 entfernt liegende Faltlinie 8 auf die benachbarte Sackwand greift und dort mit einem Klebstoffauftrag vollflächig verklebt wird. Diese Verklebung erfolgt erst, wenn die Bodenklappen 9, 10 bereits eingeklappt sind, sodass der Streifen 14 über den gefalteten Boden 4 ragt.The bottom cover sheet 12 is provided over its length, which corresponds to the width of the subsequent bag, with a strip 14 which engages over the lying away from the bottom cover sheet 12 fold line 8 on the adjacent bag wall and is glued there over the entire surface with an adhesive application. This bonding takes place only when the bottom flaps 9, 10 are already folded, so that the strip 14 projects beyond the folded bottom 4.

Es ist erkennbar, dass der Klebstoffauftrag auf dem nicht mit der Ventilöffnung 3 versehenen Boden 3 anders erfolgt als für den Boden 4, der die Ventilöffnung 13 ausbildet. Üblicherweise wird die Ventilöffnung durch einen eingelegten, gefalteten Ventilzettel ausgebildet. Hierauf wird bei dem erfindungsgemäßen Sack vorzugsweise verzichtet.It can be seen that the adhesive is applied differently to the bottom 3, which is not provided with the valve opening 3, than to the bottom 4, which forms the valve opening 13. Usually, the valve opening is formed by an inserted, folded valve leaflets. This is preferably dispensed with in the bag according to the invention.

Als Alternative zu der beschriebenen Sackkonstruktion kann eine Bodenausbildung verwendet werden, wie sie in der EP 1 914 173 B1 beschrieben ist. Bei diesem Boden befindet sich die Ventilöffnung zwischen den Bodenklappen 9, 10 und dem Bodendeckblatt 12. Die Bodenklappen haben dabei keinen oder einen nur geringen Überlappungsgrad.As an alternative to the described sack construction, a bottom formation can be used as in the EP 1 914 173 B1 is described. In this floor is the valve opening between the bottom flaps 9, 10 and the bottom cover sheet 12. The bottom flaps have no or only a small degree of overlap.

Erfindungsgemäß wird zumindest der kritische Klebstoffauftrag für den Boden 4, der mit der Ventilöffnung 13 versehen wird mit einem Dextrinkleber, vorzugsweise mit Maltodextrin, ausgeführt. Besonders bevorzugt ist es, wenn auch der andere Boden 3 mit einem Dextrinkleber verklebt wird. Selbstverständlich kann auch die Längsnaht, die zur Bildung des Schlauchs 1 aus dem flachliegenden Material der Sackwandung 2 mit dem Dextrinkleber - vorzugsweise Maltodextrin - gebildet werden.According to the invention, at least the critical adhesive application for the bottom 4, which is provided with the valve opening 13, is carried out with a dextrin adhesive, preferably with maltodextrin. It is particularly preferred if the other bottom 3 is also glued to a dextrin adhesive. Of course, the longitudinal seam, which are formed to form the tube 1 from the flat material of the bag wall 2 with the dextrin adhesive - preferably maltodextrin.

Der dargestellte Sack eignet sich insbesondere als Zementsack, der mit seinem Zementinhalt in geschlossener Form in den Betonmischer geworfen werden kann, weil er sich dort in der erdfeuchten Umgebung, die durch Wasser und Sand, vorzugsweise versehen mit Kies, gebildet wird. Hierzu besteht die Sackwandung 2 aus an sich bekanntem wasserlöslichen Papier, das Stärke in nur geringen Mengen enthält und als nicht geleimtes Papier verwendet wird.The bag shown is particularly suitable as a cement bag, which can be thrown with its cement content in a closed form in the concrete mixer, because he is there in the humid environment, which is formed by water and sand, preferably provided with gravel. For this purpose, the bag wall 2 consists of per se known water-soluble paper containing starch in only small amounts and is used as non-sized paper.

Die erfindungsgemäßen Säcke eignen sich ferner zur Befüllung mit Fasermaterialien, die einem Beton, einem Estrich o. dgl. zugegeben werden. Auch für diese Anwendungsfälle kann der erfindungsgemäße wasserlösliche Sack verwendet werden, da er sich für die Endmischung unschädlich vollständig auflöst. Auch für die Zugabe von Fasermaterialien zu aushärtenden Mischungen ergibt sich der Vorteil, dass das Ausschütten der Fasermaterialien in die Mischvorrichtung vermieden wird, sodass die Belastung durch feine Stäube und insbesondere gesundheitlich bedenkliche feine Faseranteile vermieden werden kann.The bags according to the invention are also suitable for filling with fiber materials which are added to a concrete, a screed or the like. Also for these applications, the water-soluble bag according to the invention can be used because it completely dissolves completely harmless to the final mixture. Also for the addition of fiber materials to curing mixtures there is the advantage that the dumping of the fiber materials is avoided in the mixing device, so that the burden of fine dusts and especially harmful to health fine fiber components can be avoided.
