- tear perforations limit the full tear area. Because according to the invention the opening direction of the opening formed by the opening Tear strip runs parallel to the floor, should in itself Tear perforation in a closed line on the jacket wall circulate to the thought of complete removal to realize the soil. Such a tear perforation would reduce the stability of the bag too much and the danger bursting of the sack in the area of the tear perforation when throwing the filled sack from a greater height. According to the invention, the tear perforation only extends over a small part of the width of the jacket wall, preferably only over a few centimeters, preferably no more than half the wide side wall of the filled sack.
- the front line is offset from each layer in the tear direction the front line of the layer located further outside only the tear-open perforation of the outermost layer has to be pressed in or captured and only gripped the outermost layer will. If in a preferred embodiment the tear strips the position are glued together, the tear strips of the layers underneath automatically by the staggered Arrangement of the front lines lifted off.
- the parallel longitudinal lines of the layers offset are arranged to each other, the expediently Distance between the parallel longitudinal lines of one inner layer is smaller than that of an outer layer. Thereby remains the residual risk of the perforation lines bursting further reduced.
- the tear perforation according to the invention can be done in a simple manner on three sides with two parallel to each other in the tear direction Longitudinal lines and one the ends of the longitudinal lines with each other connecting front line perpendicular to them be trained.
- the tear strip thus formed must go through Pushing or reaching behind the perforations from the rest Cladding wall can be solved. This is conveniently done by pressing in or reaching behind the forehead line.
- Tear perforations according to the invention can also occur multiple times a sack may be provided, for example in alignment with one another on its front and back or independently near both bottoms of the sack.
- the multilayer sack shown in FIG. 1 has two bottoms 1, 2 on which are produced as cross bottoms from the tubular Sheath wall 3 are folded.

Abstract
Description
Die Erfindung betrifft einen mehrlagigen 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 multi-layer paper bag with two preferably rectangular floors and one arranged in between tubular, when filled, the rectangular shape of the cladding wall adopting the floors
Derartige Papiersäcke werden aus einer mehrlagigen, zu Schläuchen verklebten Mantelwandung hergestellt, wobei die Böden aus dem Schlauchmaterial herausgefaltet werden. Kreuzbodensäcke entstehen durch Faltungen eines schlauchförmigen Mantels, der zwischen äußeren Seitenkanten flach gelegt ist, während Blockböden durch Faltung eines Mantelschlauchs mit Seitenfalten entstehen.Such paper bags are made of a multi-layer, to tubes glued jacket wall made, the floors from the hose material are folded out. Cross-bottom bags are created by folding a tubular jacket between outer side edges is laid flat, while block bottoms by folding a jacket hose with 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 opened through an opening in the bottom, which can be provided with a valve hose, or through the still open bottom filled.
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 customer, the sack is removed from this opened to the filling material formed by bulk material to get there, so to be able to empty the sack. To do this the sack wall often cut open.
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 open the sack yourself with opening aids Mistake. Such opening aids are in numerous embodiments known. DE 40 10 822 A1 is a ripping device discloses an opening of the bottom over the entire Cross bottom width allows. This opening at least allows one partial opening of the corner folds to remove the filling material. The opening in the bottom area has the advantage that the bag stability remains unaffected, however, the disadvantage that the Tearing open against considerable resistance occurs and thus is difficult to cope with. In addition, one is off Desired complete emptying of the Sackes past the remaining floor parts in daily use not regularly realized.
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 tear open a paper bag or paper bags with perforations, which extend over part of the floor area and the subsequent Extend part of the narrow side wall of the paper bag. The part torn off is down on the side wall folded, but as a flap can hinder the emptying of the sack. A complete emptying is also in practice not possible.
Durch US-A-3 175 752 und CH-A-384 452 sind durch Schweißung verschlossene Kunststoffverpackungen bekannt, deren Mantelwand durch eine aufgeklebte Aufreißlasche im Bereich der Aufreißlasche aufgerissen werden kann. Gemäß US-A-3 175 752 befindet sich unter der Aufreißlasche eine den Beginn des Aufreißens definierende Stanzung in der Kunststoffolie.US-A-3 175 752 and CH-A-384 452 are weld sealed Plastic packaging known, the jacket wall through a glued-on pull tab in the area of the pull tab can be torn open. According to US-A-3 175 752 under the tear-open tab defines the start of the tear-open Die cut in the plastic film.
Der Erfindung liegt 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.The invention has for its object a paper bag to provide an opening aid mentioned at the beginning, the a complete emptying of the paper bag in daily use allows the stability of the paper bag not noticeably affected and is easy to open.
Zur Lösung dieser Aufgabe ist ein einlagiger Papiersack der eingangs erwähnten Art erfindungsgemäß gelöst durch wenigstens einen in der Mantelwandung parallel zu einem Boden verlaufenden, durch Aufreißperforationen mit jeweils in Aufreißrichtung gerichteten Längslinien und einer die Längslinien verbindenden Stirnlinie gebildeten Aufreißstreifen der sich nur über einen geringen Teil der Breite der Mantelwandung erstreckt, wobei die Stirnlinie jeder inneren Lage in Aufreißrichtung versetzt gegenüber der Stirnlinie der weiter außen befindlichen Lage angeordnet ist.To solve this problem, a single-layer paper bag is the entrance mentioned type according to the invention solved by at least one in the jacket wall running parallel to a floor, by tearing perforations with each directed in the tearing direction Longitudinal lines and one connecting the longitudinal lines Tear line formed tear strip of only one extends small part of the width of the jacket wall, the The front line of each inner layer is offset in the tear direction the front line of the layer located further outside is.
Bei den bekannten Lösungen für Papiersäcke begrenzen Aufreißperforationen den vollständigen Aufreißbereich. Da erfindungsgemäß 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.In the known solutions for paper sacks, tear perforations limit the full tear area. Because according to the invention the opening direction of the opening formed by the opening Tear strip runs parallel to the floor, should in itself Tear perforation in a closed line on the jacket wall circulate to the thought of complete removal to realize the soil. Such a tear perforation would reduce the stability of the bag too much and the danger bursting of the sack in the area of the tear perforation when throwing the filled sack from a greater height. According to the invention, the tear perforation only extends over a small part of the width of the jacket wall, preferably only over a few centimeters, preferably no more than half the wide side wall of the filled sack. It has been shown that with the tear perforation so formed formed tear strips a full opening of the sack by tearing it open parallel to the floor is possible, the one specified by the tear perforation Tear-open direction, therefore, also not with a tear-open perforation provided area is maintained. If necessary a short tear perforation on the front and back of the Sackes should be provided.
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 rotating it To tear open the jacket wall below the floor, without noticeably weakening the sack, as a tear perforation in the claimed short length in the usual Very insensitive to bursting due to the filling material pressure is. To open the paper sack according to the invention only need the layers of the jacket wall are torn open, what about the comparable opening of the numerous floor layers only one requires little effort.
Da die Stirnlinie jeder Lage in Aufreißrichtung versetzt gegenüber der Stirnlinie der weiter außen befindlichen Lage angeordnet ist, muß nur die Aufreißperforation der äußersten Lage eingedrückt bzw. hinterfaßt und nur die äußerste Lage ergriffen werden. 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.Since the front line is offset from each layer in the tear direction the front line of the layer located further outside only the tear-open perforation of the outermost layer has to be pressed in or captured and only gripped the outermost layer will. If in a preferred embodiment the tear strips the position are glued together, the tear strips of the layers underneath automatically by the staggered Arrangement of the front lines lifted off.
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 can also be provided that the parallel longitudinal lines of the layers offset are arranged to each other, the expediently Distance between the parallel longitudinal lines of one inner layer is smaller than that of an outer layer. Thereby remains the residual risk of the perforation lines bursting further reduced.
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 perforation according to the invention can be done in a simple manner on three sides with two parallel to each other in the tear direction Longitudinal lines and one the ends of the longitudinal lines with each other connecting front line perpendicular to them be trained. The tear strip thus formed must go through Pushing or reaching behind the perforations from the rest Cladding wall can be solved. This is conveniently done by pressing in or reaching behind the forehead line.
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 perforations according to the invention can also occur multiple times a sack may be provided, for example in alignment with one another on its front and back or independently near both bottoms of the sack.

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 in der äußeren
Sacklage, 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
