Description

Die Erfindung betrifft einen Papiersack mit zwei vorzugsweise rechteckigen Böden und einer dazwischen angeordneten schlauchartigen, im gefüllten Zustand die rechteckige Form der Böden annehmenden Mantelwandung.The invention relates to a paper sack with two preferably rectangular bottoms and a tube-like jacket arranged in between, which in the filled state takes on the rectangular shape of the bottoms of the jacket wall.

Derartige Papiersäcke werden aus einer zu einem Schlauch verklebten Mantelwandung hergestellt, wobei die Böden aus dem Schlauchmaterial heraus gefaltet werden. Kreuzbodensäcke entstehen durch Faltungen eines schlauchförmigen Mantels, der zwischen äußeren Seitenkanten flach gelegt ist, während Blockböden durch Faltung eines Mantelschlauchs mit Seitenfalten entstehen.Paper bags of this type are produced from a jacket wall glued to form a tube, the bottoms being folded out of the tube material. Cross-bottom bags are created by folding a tubular jacket that is laid flat between the outer side edges, while block bottoms are created by folding a jacket tube with side gussets.

Derartige Säcke werden üblicherweise über eine Öffnung im Boden, die mit einem Ventilschlauch versehen sein kann, oder durch den noch offenen Boden selbst gefüllt.Such bags are usually filled through an opening in the bottom, which can be provided with a valve tube, or through the still open bottom itself.

Nach dem Transport des Sackes zum Endabnehmer wird der Sack von diesem geöffnet, um an das durch Schüttgut gebildete Füllgut heranzukommen, den Sack also entleeren zu können. Hierzu wird die Sackwandung häufig aufgeschnitten.After the sack has been transported to the end user, the sack is opened by the latter in order to access the filling material formed by the bulk material, that is to say to be able to empty the sack. The wall of the sack is often cut open for this purpose.

Es ist bereits bekannt, den Sack selbst mit Öffnungshilfen zu versehen. Derartige Öffnungshilfen sind in zahlreichen Ausführungsformen bekannt. In der DE 40 10 822 A1 ist eine Aufreißvorrichtung offenbart, die eine Öffnung des Bodens über die gesamte Kreuzbodenbreite ermöglicht. Diese Öffnung erlaubt eine wenigstens teilweise Öffnung der Eckeinschläge zur Entnahme des Füllguts. Die Öffnung im Bodenbereich hat den Vorteil, daß die Sackstabilität unbeeinträchtigt bleibt, jedoch den Nachteil, daß das Aufreißen gegen einen erheblichen Widerstand erfolgt und somit nur schwierig zu bewältigen ist. Darüber hinaus ist eine aus Entsorgungsgründen wünschenswerte vollständige Entleerung des Sackes an den verbleibenden Bodenteilen vorbei im täglichen Gebrauch regelmäßig nicht zu realisieren.It is already known to provide the sack itself with opening aids. Such opening aids are in numerous embodiments known. DE 40 10 822 A1 discloses a tear-open device which enables the floor to be opened over the entire width of the cross floor. This opening allows an at least partial opening of the corner folds in order to remove the filling material. The opening in the bottom area has the advantage that the bag stability remains unaffected, but the disadvantage that the tearing takes place against considerable resistance and is therefore difficult to manage. In addition, a complete emptying of the sack past the remaining parts of the floor, which is desirable for disposal reasons, cannot regularly be achieved in daily use.

Durch DE 89 01 432 U1 ist es bekannt, das Aufreißen eines Papiersackes oder Papierbeutels mit Perforationen zu ermöglichen, die sich über einen Teil des Bodenbereichs sowie den anschließenden Teil der schmalen Seitenwand des Papiersackes erstrecken. Der dabei abgerissene Teil wird auf die Seitenwand nach unten geklappt, kann aber als Klappe die Entleerung des Sackes behindern. Eine restfreie Entleerung ist in der Praxis ebenfalls nicht möglich.From DE 89 01 432 U1 it is known to enable the tearing open of a paper bag or paper bag with perforations which extend over part of the base area and the subsequent part of the narrow side wall of the paper bag. The part torn off is folded down onto the side wall, but as a flap can hinder the emptying of the sack. A complete emptying is also not possible in practice.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, einen Papiersack der eingangs erwähnten Art mit einer Öffnungshilfe zu versehen, die im täglichen Gebrauch eine restlose Entleerung des Papiersacks ermöglicht, die Stabilität des Papiersacks nicht merklich beeinträchtigt und leicht zu öffnen ist.In contrast, the invention is based on the object of providing a paper sack of the type mentioned at the outset with an opening aid which enables the paper sack to be emptied completely in daily use, does not noticeably impair the stability of the paper sack and is easy to open.

Zur Lösung dieser Aufgabe ist ein Papiersack der eingangs erwähnten Art erfindungsgemäß durch einen in der Mantelwandung parallel zu einem Boden verlaufenden, durch Aufreißperforationen gebildeten Aufreißstreifen gelöst, der sich nur über einen geringen Teil der Breite der Mantelwandung erstreckt.To achieve this object, a paper sack of the type mentioned at the outset is achieved according to the invention by a tear strip, which runs parallel to a floor in the jacket wall and is formed by tear perforations and extends only over a small part of the width of the jacket wall.

üblicherweise begrenzen Aufreißperforationen den vollständigen Aufreißbereich. Da die Aufreißrichtung des durch die Aufreißperforation gebildeten Aufreißstreifens parallel zum Boden verläuft, müßte an sich die Aufreißperforation in einer geschlossenen Linie auf der Mantelwand umlaufen, um den Gedanken einer vollständigen Entfernung des Bodens zu verwirklichen. Eine solche Aufreißperforation würde die Stabilität des Sackes zu stark herabsetzen und die Gefahr des Aufplatzens des Sackes im Bereich der Aufreißperforation beim Abwerfen des gefüllten Sackes aus größerer Höhe hervorrufen. Erfindungsgemäß erstreckt sich die Aufreißperforation nur über einen geringen Teil der Breite der Mantelwandung, vorzugweise nur über einige Zentimeter, vorzugsweise über nicht mehr als die Hälfte der breiten Seitenwand des gefüllten Sackes. Es hat sich gezeigt, daß mit dem durch die so ausgebildte Aufreißperforation gebildeten Aufreißstreifen eine vollständige Öffnung des Sackes durch ein umlaufendes Aufreißen parallel zum Boden möglich ist, die durch die Aufreißperforation einmal vorgegebene Aufreißrichtung also auch in dem nicht mit einer Aufreißperforation versehenen Bereich beibehalten wird. Gegebenenfalls kann eine kurze Aufreißperforation auf Vorder- und Rückseite des Sackes vorgesehen sein.Tear perforations usually limit the full tear area. Since the tear-open direction of the tear-off strip formed by the tear-open perforation runs parallel to the floor, the tear-open perforation itself would have to run in a closed line on the jacket wall in order to ensure the idea of a complete one Realize removal of the soil. Such a tear-open perforation would reduce the stability of the bag too much and would cause the bag to burst open in the area of the tear-open perforation when the filled bag is dropped from a greater height. According to the invention, the tear-open perforation extends only over a small part of the width of the jacket wall, preferably only over a few centimeters, preferably over not more than half the wide side wall of the filled sack. It has been shown that with the tear strip formed by the tear perforation thus formed, a full opening of the sack is possible by tearing open all the way parallel to the floor, and the tear direction once predetermined by the tear perforation is thus also maintained in the area not provided with a tear perforation. If necessary, a short tear perforation can be provided on the front and back of the sack.

Dadurch ist es möglich, die Öffnung des Sackes durch ein umlaufendes Aufreißen der Mantelwandung unterhalb des Bodens vorzunehmen, ohne den Sack merklich zu schwächen, da eine Aufreißperforation in der beanspruchten geringen Länge in der üblichen Ausführung gegen Aufplatzen durch den Füllgutdruck sehr unanfällig ist. Zum Öffnen des erfindungsgemäßen Papiersacks müssen nur die Lagen der Mantelwandung aufgerissen werden, was gegenüber dem vergleichbaren Öffnen der zahlreichen Bodenlagen einen nur geringen Kraftaufwand erfordert.This makes it possible to open the sack by tearing open the jacket wall underneath the bottom without noticeably weakening the sack, since a tear-open perforation in the claimed short length is very unaffected by the filling pressure in the usual design against bursting. To open the paper sack according to the invention, only the layers of the jacket wall have to be torn open, which requires only little effort compared to the comparable opening of the numerous base layers.

Die erfindungsgemäße Aufreißperforation kann in einfacher Weise dreiseitig mit zwei in Aufreißrichtung parallel zueinander verlaufenden Längslinien und einer die Enden der Längslinien miteinander verbindenden, senkrecht zu ihnen stehenden Stirnlinie ausgebildet sein. Der so gebildete Aufreißstreifen muß durch Eindrücken oder Hintergreifen der Perforationen von der übrigen Mantelwandung gelöst werden. Dies geschieht zweckmäßigerweise durch Eindrücken oder Hintergreifen der Stirnlinie.The tear-open perforation according to the invention can be designed in a simple manner on three sides with two longitudinal lines running parallel to one another in the tear-open direction and one end line perpendicular to them connecting the ends of the longitudinal lines. The tear strip thus formed must be detached from the rest of the jacket wall by pressing in or engaging behind the perforations. This is expediently done by pressing in or reaching behind the front line.

Besondere Vorteile bietet der erfindungsgemäße Papiersack in mehrlagiger Ausbildung, wenn die Stirnlinie jeder Lage in Aufreißrichtung versetzt gegenüber der Stirnlinie der weiter außen befindlichen Lage angeordnet ist. Dadurch wird erreicht, daß nur die Aufreißperforation der äußersten Lage eingedrückt bzw. hinterfaßt und nur die äußerste Lage ergriffen werden muß. Wenn in einer bevorzugten Ausführungsform die Aufreißstreifen der Lage miteinander verklebt sind, werden die Aufreißstreifen der darunterliegenden Lagen automatisch durch die gestaffelte Anordnung der Stirnlinien abgehoben.The paper sack according to the invention offers particular advantages in a multilayer design if the end line of each layer is arranged offset in the tear direction relative to the end line of the layer located further out. This ensures that only the tear-open perforation of the outermost layer is pressed in or gripped behind and only the outermost layer has to be gripped. If, in a preferred embodiment, the tear strips of the layer are glued together, the tear strips of the layers below are automatically lifted off by the staggered arrangement of the end lines.

Zur Erhöhung der Stabilität kann ferner vorgesehen sein, daß die parallel zueinander verlaufendenden Längslinien der Lagen versetzt zueinander angeordnet sind, wobei zweckmäßigerweise der Abstand der parallel zueinander verlaufenden Längslinien einer inneren Lage kleiner ist als der einer äußeren Lage. Dadurch wird das Restrisiko des Aufplatzens der Perforationslinien noch weiter verkleinert.To increase the stability, it can further be provided that the parallel longitudinal lines of the layers are arranged offset from one another, the distance between the parallel longitudinal lines of an inner layer advantageously being smaller than that of an outer layer. This further reduces the residual risk of the perforation lines bursting open.

Erfindungsgemäße Aufreißperforationen können auch mehrfach an einem Sack vorgesehen sein, beispielsweise miteinander fluchtend auf seiner Vorder- und Rückseite oder unabhängig voneinander nahe beiden Böden des Sackes.Tear-off perforations according to the invention can also be provided multiple times on a sack, for example in alignment with one another on its front and back or independently of one another near both bottoms of the sack.

Die Erfindung wird im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

Figure 2 -
3 shows an enlarged representation of tear strips of a three-layer sack according to FIG. 1, torn open along perforation lines.

Der in Figur 1 dargestellte Sack weist zwei Böden 1,2 auf, die als Kreuzböden aus der schlauchförmig hergestellten Mantelwandung 3 gefaltet sind. Der obere Boden 2 weist ein schematisch dargestelltes Außenventil 4 auf, über das der im übrigen geschlossene Sack mit Füllgut befüllt werden kann.The sack shown in FIG. 1 has two bottoms 1, 2, which are folded as cross bottoms from the tubular wall 3. The upper base 2 has a schematically represented external valve 4, via which the otherwise closed sack can be filled with filling material.

Nach der Befüllung nimmt die Mantelwandung 3 im Querschnitt im wesentlichen die rechteckige Form der Böden 1,2 an und besteht somit aus zwei großen Seitenwänden 5 und zwei schmalen Seitenwänden 6.After filling, the jacket wall 3 essentially assumes the rectangular shape of the bottoms 1, 2 in cross section and thus consists of two large side walls 5 and two narrow side walls 6.

Unterhalb des oberen Bodens 2 weist der Sack mittig in der großen Seitenwand 5 eine Aufreißperforation 7 auf, die aus zwei zueinander parallelen Längslinien 8 und einer die einseitigen Enden der Längslinien 8 verbindenden, dazu senkrecht stehenden Stirnlinie 9 besteht. Diese drei Perforationslinien 8,9 definieren das freie Ende eines Aufreißstreifens 10, der von der Stirnseite 9 aus geöffnet und in Richtung des Pfeiles 11 gezogen werden kann, um nach einem vollständigen Umlauf den oberhalb des Aufreißstreifens 10 befindlichen Teil der Mantelwandung 3 zusammen mit dem zugehörigen Boden 2 von dem verbleibenden Teil der Mantelwandung 3 mit dem Boden 1 zu trennen. Dadurch entsteht ein oben vollständig offener Sack, der ohne Schwierigkeiten restfrei entleert werden kann.Below the upper base 2, the sack has a tear-open perforation 7 in the middle of the large side wall 5, which consists of two parallel longitudinal lines 8 and a front line 9 that connects the one-sided ends of the longitudinal lines 8 and is perpendicular to it. These three perforation lines 8, 9 define the free end of a tear strip 10, which can be opened from the end face 9 and pulled in the direction of the arrow 11 in order to, after a complete revolution, the part of the casing wall 3 located above the tear strip 10 together with the associated one Separate bottom 2 from the remaining part of the casing wall 3 with the bottom 1. This creates a completely open sack that can be emptied without any problems.

Figur 2 verdeutlicht die Ausbildung der Öffnungshilfe bei einer dreilagigen Mantelwandung 3. Jede der Mantelwandungen bildet einen Aufreißstreifen 10,10',10'', die jeweils an den aneinanderliegenden Flächen miteinander verklebt sind. Figur 2 zeigt die Aufreißstreifen 10,10',10'' nach der Trennung von den zugehörigen Lagen der Mantelwandung 3 entlang den Perforationslinien 8,9; 8',9' bzw. 8'',9''. Dabei ist deutlich, daß die Stirnlinie 9'' der innersten Lage in Aufreißrichtungen 11 gegenüber der Stirnlinie 9' der mittleren Lage und diese wiederum gegenüber der Stirnlinie 9 der äußeren Lage versetzt ist.Figure 2 illustrates the design of the opening aid in a three-layer jacket wall 3. Each of the jacket walls forms a tear strip 10, 10 ', 10'', which are glued to each other on the adjoining surfaces. Figure 2 shows the tear strips 10, 10 ', 10''after separation from the associated layers of the casing wall 3 along the perforation lines 8, 9; 8 ', 9' or 8 '', 9 ''. It is clear that the end line 9 ″ of the innermost layer is in the tear-open directions 11 with respect to the end line 9 ′ of the middle layer and this in turn is offset with respect to the end line 9 of the outer layer.

In entsprechender Weise sind die zueinander parallel verlaufenden Perforationslinien 8 bzw. 8' und 8'' zueinander versetzt, wobei die beiden Perforationslinien 8'' einen geringeren Abstand voneinander aufweisen als die Perforationslinien 8' und diese wieder einen geringeren Abstand aufweisen als die Perforationslinien 8. Hieraus resultiert, daß der Aufreißstreifen 10'' der inneren Lage schmaler und kürzer ist als der Aufreißstreifen 10' der mittleren Lage und dieser wieder kürzer und schmaler als der Aufreißstreifen 10 der äußeren Lage.Correspondingly, the perforation lines 8 or 8 ′ and 8 ″, which run parallel to one another, are offset from one another, the two perforation lines 8 ″ being at a smaller distance from one another than the perforation lines 8 ′ and again being at a smaller distance than the perforation lines 8. The result of this is that the tear strip 10 ″ of the inner layer is narrower and shorter than the tear strip 10 ′ of the middle layer and this again is shorter and narrower than the tear strip 10 ″ of the outer layer.

Da die Aufreißstreifen 10,10',10'' miteinander verklebt sind, reicht das Ziehen an dem äußeren Aufreißstreifen 10 aus, um auch die Aufreißstreifen 10',10'' von ihren Lagen zu trennen.Since the tear strips 10, 10 ', 10' 'are glued to one another, pulling on the outer tear strip 10 is sufficient to also separate the tear strips 10', 10 '' from their positions.

Figur 2 zeigt den Zustand der entlang den Perforationslinien 8,9; 8',9'; 8'',9'' aufgerissenen Aufreißstreifen 10,10',10'', die in diesem Zustand weiter in Aufreißrichtung 11 umlaufend um die gesamte Mantelwandung 3 gezogen werden, um den oberen Teil des Sackes abzutrennen.Figure 2 shows the state of the along the perforation lines 8,9; 8 ', 9'; 8 ″, 9 ″ tear-open strips 10, 10 ′, 10 ″, which in this state are pulled further around the entire jacket wall 3 in the tear direction 11 in order to separate the upper part of the sack.
