Description

Aus mehreren Lagen bestehender Papierbeutel oder Papiersack Die Erfindung betrifft Papiersäcke oder Papierbeutel zum Einfüllen von pulverförmigen Stoffen, wie Mehl oder Zement. Derartige Beutel werden gewöhnlich aus mehreren Papierlagen hergestellt, von denen die inneren Lagen mit Einrichtungen versehen sind, die die beim Einfüllen mit hineingerissenen Luftmengen entweichen lassen, beispielsweise zu diesem Zweck durchlocht sind.Multi-layer paper bag or paper sack The invention concerns paper sacks or paper bags for filling powdery substances, like flour or cement. Such bags are usually made of several layers of paper produced, of which the inner layers are provided with devices that the when filling with torn air to escape, for example are perforated for this purpose.

Die beim Einfüllen mit in den Beutel hineingerissene Luft findet einen Ausweg zwischen der äußeren luftundurchlässigen Lage des Beutels und den inneren, beispielsweise mit Löchern versehenen Lagen und ermöglicht dadurch ein schnelles Zusammensetzen des eingefüllten Gutes. Diese Luft ist stets mit einer erheblichen Menge von Staub des eingefüllten Mehles, Zementes o. dgl, beladen, der beim Entweichen der Luft durch den engen Zwischenraum zwischen der äußeren Lage und den inneren Lagen herausgeschleudert und in der umgebenden Luft verbreitet wird. Um dies zu verhindern, ist erfindungsgemäß der obere Rand der äußeren Papierlage über die inneren Lagen nach innen ohne weitere Befestigung umgeklappt. Durch den umgeklappten Rand werden die inneren Papierlagen, auch wenn sie nicht am Boden des Beutels befestigt sind, in diesem festgehalten. Der zwischen der äußeren und den inneren Papierlagen entweichende Luftstrom wird durch diesen umgeklappten Rand in das Innere des Beutels oder Sackes hineingeleitet, so daß der größte Teil des zerstäubten Gutes in diesen hineinfällt.The air that was torn into the bag when it was filled finds one Way out between the outer airtight layer of the bag and the inner, For example, layers provided with holes and thus enables a quick Assembling the filled goods. This air is always with a considerable Amount of dust from the flour, cement or the like loaded, which escapes the air through the narrow space between the outer layer and the inner layer Layers are thrown out and spread in the surrounding air. To do this prevent, according to the invention, the upper edge of the outer paper layer over the inner Layers folded inwards without further fastening. Through the folded edge the inner paper layers, even if they are not attached to the bottom of the bag are recorded in this. The one between the outer and inner layers of paper Escaping air flow is through this folded edge into the interior of the bag or sack, so that most of the atomized material is in these falls into it.

Das Umschlagen des oberen Randes der äußeren Papierlage über die innere Lage ist bei mehrlagigen Papierbeuteln an sieh bereits bekannt, jedoch handelt es sich hier nicht um solche Beutel, bei denen die inneren Papierlagen luftdurchlässig sind, so daß bei den bekannten Ausführungen der Rand nicht die Wirkung haben kann, die zwischen den Papierlagen durchströmende Luft in den Beutel hineinzuleiten. Die Zeichnung zeigt als Ausführungsbeispiel einen Papierbeutel zum Verpacken von Mehl. Fig. i ist eine Ansicht des Beutels; Fig. 2 zeigt die auseinandergefaltete Einlage.Folding the top edge of the outer paper layer over the inner one Location is already known for multi-layer paper bags, but it is These are not bags in which the inner paper layers are permeable to air are, so that in the known designs, the edge cannot have the effect to direct the air flowing through between the paper layers into the bag. the The drawing shows, as an exemplary embodiment, a paper bag for packing flour. Figure i is a view of the pouch; Fig. 2 shows the expanded insert.

Der in Fig. r dargestellte ECreuzbodenbeutel i ist in üblicher Weise mit Einlagen versehen, die aus einer inneren Papierlage 2 und einer äußeren Papierlage 3 besteht. Die Ränder q. und 5 dieser Papierlagen sind zusammengeklebt und gegeneinander versetzt. Das untere Ende der Einlagen ist in den Kreuzboden eingeklebt, dagegen sind ihre oberen Enden nicht miteinander und mit der Wand des Beutels i verklebt, sondern werden durch den nach innen eingeklappten Rand 6 der äußeren luftundurchlässigen Hülle i mit dieser zusammengehalten.The cross-bottom bag i shown in FIG. R is in the usual way provided with inserts consisting of an inner paper layer 2 and an outer paper layer 3 exists. The edges q. and 5 of these paper layers are glued together and against each other offset. The lower end of the inlays is glued into the bottom of the cross, on the other hand their upper ends are not glued to each other and to the wall of the bag i, but are made air-impermeable by the inwardly folded edge 6 of the outer Sheath i held together with this.

In den beiden Papierlagen 2 und 3 sind in beliebiger Anordnung Löcher eingestanzt, die in beiden Lagen gegeneinander versetzt sind. In dem gezeichneten Ausführungsbeispiel trägt die äußere Papierlage 3 Gruppen von je vier Löchern 7 und die innere Papierlage z entsprechende Lochgruppen 8, die so angeordnet sind, daß sich die Löcher beider Gruppen an keiner Stelle decken. Fig. 2 zeigt den aus den beiden Lagen 2 und 3 gebildeten Papierschlauch teilweise auseinandergefaltet.There are holes in any arrangement in the two paper layers 2 and 3 punched in, which are offset from one another in both layers. In the drawn In the exemplary embodiment, the outer paper layer has 3 groups of four holes 7 each and the inner paper layer z corresponding hole groups 8, which are arranged so that the holes of both groups do not coincide at any point. Fig. 2 shows the off the two layers 2 and 3 formed paper tube partially unfolded.

Die Anzahl der Papierlagen, von denen die innerste oder mehrere Lagen mit Löchern versehen werden oder porös sein können, ist beliebig. An Stelle von Löchern können auch Schlitze u. dgl. angebracht werden. Auch kann die innerste Schicht der Einlage anstatt aus Papier aus einem anderen Stoff, beispielsweise aus einem stark luftdurchlässigen Gewebe, bestehen.The number of layers of paper, the innermost or multiple layers be provided with holes or can be porous is arbitrary. Instead of Slots and the like can also be made through holes. The innermost layer can too the insert instead of paper made from another material, for example from a highly breathable fabric.
