Description

Papiersack paper bags
Die Erfindung betrifft einen Papiersack gemäß Oberbegriff des Anspruchs 1:The invention relates to a paper bag according to the preamble of claim 1:
Papiersäcke werden üblicherweise als Ventilbodensäcke oder Blockbodensäcke für die Aufnahme von Schüttgut zur Verfügung gestellt und weisen einen Standboden, einen Ventilboden, eine Vorderseite, eine Rückseite und einen in den Ventilboden eingesetzten Ventilschlauch zum Aufstecken auf den Füllstutzen einer Füllvorrichtung auf, wobei der Ventilschlauch durch Umlegen verschlossen oder im Falle von Thermomaterial verschweißt werden kann. Ein derartiger Ventilbodensack ist beispielsweise aus dem Deutschen Gebrauchsmuster DE-20 2005 004 750 Ul bekannt.Paper sacks are usually provided as valve bottom bags or block bottom bags for receiving bulk material and have a bottom, a valve bottom, a front, a back and a valve tube inserted into the valve bottom for attachment to the filler neck of a filling device, the valve tube closed by folding or in the case of thermal material can be welded. Such a valve floor bag is known for example from German Utility Model DE-20 2005 004 750 Ul.
Ventilbodensäcke werden grundsätzlich mit Deckblättern versehen, die dazu dienen, das ungewollte Aufgehen der zugefalteten und verklebten Böden, nämlich des Standbodens und des Ventilbodens, zu vermeiden. Bei einem Deckblatt handelt es sich um - einen Papierstreifen oder Zettel, der auf die Böden des Papiersacks geklebt wird. Die meisten Deckblätter sind schmäler als der Boden und in der Regel nicht nur mit dem Boden, sondern auch mit dem aus dem Boden seitlich vorstehenden Ventilschlauch verklebt. Es ist aber auch bereits bekannt, die Deckblätter über die Ränder des Standbodens und des Ventilbodens bis in den Bereich der Vorderseite und der Rückseite des Papiersacks zu ziehen.Valve bottom bags are always provided with cover sheets, which serve to avoid the unwanted rising of the folded and glued bottoms, namely the floor and the valve bottom. A cover sheet is a piece of paper or paper that is glued to the bottom of the paper sack. Most cover sheets are narrower than the bottom and usually glued not only to the bottom, but also with the laterally projecting from the bottom of the valve tube. However, it is already known to pull the cover sheets over the edges of the base and the valve bottom into the region of the front and the back of the paper bag.
Zum Öffnen des mit Schüttgut befüllten Papiersacks wurde bislang das Deckblatt üblicherweise vom Standboden abgerissen, was allerdings den Nachteil mit sich brachte, daß Papierfasern in das Produkt fallen konnten, was nicht in jedem Fall toleriert wird. In dem Zusammenhang ist es zum leichteren Aufrei- ßen auch bereits bekannt, das Deckblatt mit einem Aufreißstreifen gemäß Deutscher Offenlegungsschrift 1 761 750 zu versehen .To open the paper bag filled with bulk material, the cover sheet has hitherto usually been torn off the floor, which, however, has the disadvantage that paper fibers could fall into the product, which is not always tolerated. In this context, it is necessary to facilitate It is also already known to provide the cover sheet with a tear strip in accordance with German Offenlegungsschrift 1 761 750.
Aufgabe der Erfindung ist es, einen Papiersack mit Aufreißstreifen dahingehend weiterzubilden, daß beim Aufreißen keinerlei Papierfasern in das Produkt gelangen können.The object of the invention is to develop a paper bag with tear strip to the effect that when tearing any paper fibers can get into the product.
Zur Lösung dieser Aufgabe ist bei einem Papiersack der eingangs genannten Art unter dem Standboden-Deckblatt und/oder unter dem Ventilboden-Deckblatt eine Folie eingelegt und mit dem Papiersack in der Weise ablösbar verklebt ist, daß die Folie nach dem Aufreißen des Standboden- oder Ventilboden- Deckblattes den Papiersack noch vollständig verschließt und erst nach dem Abziehen das Produkt freigibt.To solve this problem, a film is inserted in a paper bag of the type mentioned under the stand-cover sheet and / or under the valve cover sheet and releasably bonded to the paper bag in the manner that the film after tearing the floor or bottom of the valve - Cover sheet still completely closes the paper bag and releases the product only after peeling off.
Dadurch wird erreicht, daß nach dem Aufreißen des Standbodens die beiden Bodenteile aufgeklappt werden können, aber der Sack zunächst noch durch die Folie verschlossen bleibt. Dadurch können keine Papierfasern in das Produkt fallen. Erst wenn man die Folie an einer Ecke erfaßt und vom Papier abzieht, wird der Sack geöffnet und das Produkt ist frei zugänglich.This ensures that after the tearing of the floor, the two bottom parts can be opened, but the bag is initially still closed by the film. This prevents paper fibers from falling into the product. Only when one grasps the film at a corner and peels off the paper, the bag is opened and the product is freely accessible.
Die Folie kann eine Kunststofffolie, eine Metallfolie, eine Papierfolie mit oder ohne Beschichtung, eine Glasfaserfolie, eine Gewebefolie oder ein Spinnvlies aus Gewebefasern sein, wobei das Folienmaterial außerdem gegebenenfalls biologisch abbaubar, kompostierbar oder recyclingfähig sein soll.The film may be a plastic film, a metal foil, a paper foil with or without a coating, a glass fiber foil, a tissue foil or a spunbond of tissue fibers, wherein the foil material should also be biodegradable, compostable or recyclable if necessary.
Die Erfindung wird nachfolgend an Hand einer Zeichnung näher erläutert; darin zeigen:The invention will be explained in more detail with reference to a drawing; show in it:
Figur 1 eine Draufsicht auf einen Papiersack mit Standboden, Ventilboden und Schlauchventil; Figur 2 eine schematische Darstellung des Standbodens beim Aufreißen;Figure 1 is a plan view of a paper bag with floor stand, valve bottom and hose valve; Figure 2 is a schematic representation of the floor during tearing;
Figur 3 den gemäß Figur 2 aufgerissenen und auseinandergeklappten Standboden, der noch durch eine Folie verschlossen ist;Figure 3 shows the torn open and unfolded according to Figure 2 floor, which is still closed by a film;
Figur 4 den Beginn des Ablösens der Folie bei gemäß Figur 3 geöffnetem Standboden;FIG. 4 shows the beginning of the detachment of the film in the case of the floor opened according to FIG. 3;
Figur 5 den bereits halb geöffneten Papiersack gemäß Figur 4;FIG. 5 shows the already half-opened paper bag according to FIG. 4;
Figur 6 den Papiersack aus Fig. 3 mit weiteren Merkmalen.FIG. 6 shows the paper bag from FIG. 3 with further features.
In den Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen. So zeigt Figur 1 einen Papiersack 1 mit einem Standboden 2 und einem Ventilboden 3, die in an sich bekannter Weise als Kreuzböden oder Blockböden gefaltet und durch je ein Deckblatt 5, 5' abgedeckt sind. Die Deckblätter 5 und 5Λ sind im dargestellten Ausführungsbeispiel über die Ränder des Standbodens 2 und des Ventilbodens 3 bis in den Bereich der Vorderwand 4 und der Rückwand geführt und auf übliche Weise mit dem Papiersack 1 verklebt.In the figures, like parts are given the same reference numerals. Thus, Figure 1 shows a paper bag 1 with a floor 2 and a bottom plate 3, which are folded in a conventional manner as Kreuzböden or block floors and covered by a respective cover sheet 5, 5 '. The cover sheets 5 and 5 Λ are guided in the illustrated embodiment over the edges of the base 2 and the valve bottom 3 into the region of the front wall 4 and the rear wall and glued in the usual way with the paper bag 1.
In dem dargestellten Ausführungsbeispiel ist ferner ein Ventilschlauch 7 in den Ventilboden 3 eingearbeitet, wie dies aus dem Stand der Technik bekannt ist, beispielsweise aus der Gebrauchsmusterschrift DE 20 2005 004 750 Ul.In the illustrated embodiment, a valve tube 7 is further incorporated into the valve bottom 3, as is known from the prior art, for example, from the utility model DE 20 2005 004 750 Ul.
In Figur 1 ist der Papiersack 1 so dargestellt, daß der Standboden 2 nach oben gerichtet ist, wie dies zum Aufreißen eines mit Produkt gefüllten Papiersacks 1 vorteilhaft wäre. Zum Aufreißen dient ein Aufreißstreifen 6, der über die gesamte Länge des Standbodens 2 verläuft und damit von einer Seite des Deckblatts 5 zur gegenüberliegenden anderen. Figur 2 zeigt nun den Vorgang des Aufreißens des Standboden- Deckblattes 5 in schematischer Darstellung, wobei nur der obere Teil des Papiersacks 1 mit Vorderwand 4 und einer Seitenwand dargestellt ist. Man erfaßt dazu den Aufreißstreifen 6 in der Nähe der Seitenwand 8 und zieht ihn Richtung des Pfeils zur gegenüberliegenden Seitenwand 8 Λ .In Figure 1, the paper bag 1 is shown so that the floor 2 is directed upwards, as would be advantageous for tearing a paper bag 1 filled with product. For tearing a tear strip 6, which extends over the entire length of the stand 2 and thus from one side of the cover sheet 5 to the opposite other. Figure 2 now shows the process of tearing the stand-cover sheet 5 in a schematic representation, wherein only the upper part of the paper bag 1 is shown with front wall 4 and a side wall. It detects the tear strip 6 in the vicinity of the side wall 8 and pulls him direction of the arrow to the opposite side wall 8 Λ .
Figur 3 zeigt den Papiersack 1 mit vollständig aufgerissenem Deckblatt 5 und auseinandergeklappten Seitenstreifen 5", wobei der Papiersack 1 jedoch noch immer durch eine eingelegte und mit den Deckblattstreifen 5" ablösbar verklebte Folie 9 aus Kunststoff geschlossen ist.Figure 3 shows the paper bag 1 with completely torn cover sheet 5 and unfolded side strips 5 ", the paper bag 1, however, is still closed by an inserted and with the cover sheet strip 5" releasably bonded film 9 made of plastic.
Zum Öffnen des Papiersacks 1 muß die Folie 9 erst von den Seitenstreifen 5" abgetrennt werden, was in Figur 4 angedeutet ist, indem eine Ecke 10 der Folie 9 erfaßt und vom Deckblatt- Seitenstreifen 5" abgelöst wird. In diesem Zustand, also wenn die Folie 9 noch nicht abgezogen wurde, ist das Produkt noch nicht freigelegt, da der Innenraum des Papiersacks 1 noch geschlossen ist.To open the paper bag 1, the film 9 must first be separated from the side strips 5 ", which is indicated in Figure 4 by a corner 10 of the film 9 is detected and the cover sheet side strip 5" is replaced. In this state, ie when the film 9 has not yet been removed, the product is not yet exposed, since the interior of the paper bag 1 is still closed.
Erst Figur 5 zeigt die noch weiter abgelöste Folie 9, die den Innenraum 11 des Papiersacks 1 freigibt. Wenn die Folie 9 dann vollständig vom Papiersack 1 abgezogen ist, besteht ungehinderter Zugang zu dem im Innenraum 11 liegenden Produkt, ohne daß dieses während des Öffnens durch Papierfasern verunreinigt worden wäre.Only Figure 5 shows the still further detached film 9, which releases the interior 11 of the paper bag 1. If the film 9 is then completely withdrawn from the paper bag 1, there is unhindered access to the lying in the interior 11 product without this would have been contaminated during opening by paper fibers.
Figur 6 zeigt eine Weiterbildung der Erfindung, bei der die Folie 9 mit einer Wiederverschließeinrichtung versehen ist. In einer ersten Variante besteht die Wiederverschließeinrichtung durch das Aufbringen von Spezialkleber oder Spezialleim, der es erlaubt, die Folie 9 beliebig oft vom Papiersack 1 zu lösen und wieder anzubringen. Derartige Spezialkleber oder Spezial- leime' sind dem Fachmann bekannt. Hierzu können Klebelinien entlang des Randes der Folie 9 vorgesehen werden oder es kann auch die gesamte Folie 9 mit einem derartigen Spezialkleber beschichtet sein.Figure 6 shows a development of the invention, in which the film 9 is provided with a reclosing device. In a first variant, the reclosing device consists of the application of special adhesive or special glue which allows the film 9 to be detached from the paper bag 1 as often as desired and to be reattached. Such special adhesive or special Glues' are known in the art. For this purpose, adhesive lines along the edge of the film 9 can be provided or it can also be the entire film 9 coated with such a special adhesive.
In einer anderen Variante ist an der Innenseite der Seitenstreifen 5" des Papiersacks 1 ein Verschluss 13 vorgesehen, der in einer Ausführungsform unter der in diesem Bereich nicht verleimten Folie 9 liegt, während in einer anderen Ausführungsform die Folie 9 schmaler ist und nicht bis zu den Rändern der Seitenstreifen 5" reicht, sondern einen Streifen freilässt, in dem die beiden Teile 13' , 13" des Verschlusses 13 angeordnet sind. Der Verschluß 13 ist in einer Ausführungsform ein Klickverschluss mit Nut und Feder, in einer anderen Ausführungsform ein Klettverschluss . Klickverschlüsse mit Nut und Feder sind von Kunststoffbeuteln her allgemein bekannt und dem Fachmann daher geläufig. Gleiches gilt für den zuvor erwähnten Klettverschluss. Zum Wiederverschließen werden die Seitenstreifen 5" des aufgerissenen Deckblattes 5 und nach abgezogener Folie 9 gegeneinander gedrückt, wodurch die Feder 13' in die Nut 13" des Verschlusses 13 eingreift. Auf ähnliche Weise wird ein Klettverschluss geschlossen, nämlich indem dessen beide Teile gegeneinander gedrückt werden. Dadurch ist der einmal geöffnete Papiersack 1 auf einfache Weise wiederverschließbar.In another variant, on the inside of the side strips 5 "of the paper bag 1, a closure 13 is provided, which lies in one embodiment under the not glued in this area film 9, while in another embodiment, the film 9 is narrower and not up to the But leaves a strip in which are located the two parts 13 ', 13 "of the closure 13. The closure 13 in one embodiment is a click-in closure with tongue and groove, in another embodiment a hook-and-loop fastener For reclosing, the side strips 5 "of the torn cover sheet 5 and, after the foil 9 removed, are pressed against one another, whereby the spring 13 'is pressed into the Groove 13 "of the closure 13. In a similar manner, a Kle Closure closed, namely by the two parts are pressed against each other. As a result, the once opened paper bag 1 is re-closable in a simple manner.
Die erfindungsgemäße Folie 9 kann bedruckt oder unbedruckt und außerdem mit Sicherheitsmerkmalen wie Bildern, Hologrammen oder Streifen versehen sein, die sicherstellen, dass sie die Folie 9 nach dem ersten Abziehen oder Ablösen vom Papiersack 1 als beschädigt erkennen lassen. Neben den erwähnten Sicherheitsmerkmalen kann die Folie aber auch mit Hinweisen über den Inhalt des Produkts oder mit Anweisungen, wie mit dem Papiersack oder dem darin enthaltenen Produkt verfahren werden soll, versehen sein. In einer weiteren Ausgestaltung der Erfindung kann die Folie 9 dazu dienen, zusammen mit dem nach innen gefalteten Boden eine Schüttvorrichtung zu bilden, wozu die Folie 9 zweckmäßigerweise im Bereich bzw. in der Nähe einer der Seitenwände 8 oder 8' nicht mit dem Papiersack 1 verklebt ist. In diesem Bereich deckt die Folie 9 zwar den Innenraum des Papiersacks 1 ab, lässt sich aber nach dem Aufreißen des Aufreißstreifens 6, das in Fig. 2 dargestellt ist, von Hand umschlagen, so dass der umgefaltete Teil des Standbodens 2 von Hand erfasst und nach außen in Richtung auf die Seitenwand 8 oder 8' gezogen werden kann. Wenn außerdem der umgefaltete Teil des Standbodens 2 mit Einschnitten versehen ist, die etwa parallel zur Vorderwand 4 bis zur Seitenwand 8 oder 8' verlaufen, dann lässt sich der umgefaltete Teil des Standbodens 2 von Hand nach außen ziehen und bildet zusammen mit dem zuvor in die andere Richtung umgefalteten Teil der unverankerten Folie 9 eine Ausschüttvorrichtung, die insbesondere dann gut zum Einsatz kommt, wenn der dem Standboden 2 gegenüberliegende Gegenboden, der in einer Ausführungsform gemäß Figur 1 als Ventilboden 3 bezeichnet ist, einen Tragegriff aufweist. Dann kann ein Benutzer den Tragegriff bequem erfassen und das Produkt durch die von der hochgeklappten Folie 9 und von dem herausgezogenen Standbodenbereich gebildete Ausschüttvorrichtung entleeren.The film 9 according to the invention can be printed or unprinted and also provided with security features such as images, holograms or stripes, which ensure that they reveal the film 9 as damaged after the first removal or detachment from the paper bag 1. In addition to the safety features mentioned, however, the film may also be provided with instructions on the contents of the product or with instructions on how to handle the paper bag or the product contained therein. In a further embodiment of the invention, the film 9 can serve to form a bulk material together with the inwardly folded bottom, for which the film 9 expediently in the area or in the vicinity of one of the side walls 8 or 8 'not glued to the paper bag 1 is. Although the film 9 covers the interior of the paper bag 1 in this area, it can be turned over by hand after the tearing strip 6, which is shown in FIG. 2, has been torn open so that the folded-over part of the base 2 is grasped by hand can be pulled outside in the direction of the side wall 8 or 8 '. In addition, if the folded-over part of the stand 2 is provided with incisions which are approximately parallel to the front wall 4 to the side wall 8 or 8 ', then the folded part of the stand 2 by hand can pull outwards and forms together with the previously in the In the other direction folded over part of the anchored film 9 a dispensing device, which is particularly well used when the standing bottom 2 opposite bottom, which is designated in an embodiment of Figure 1 as a valve bottom 3, has a carrying handle. Then a user can comfortably grasp the carrying handle and empty the product through the dispensing device formed by the folded-up film 9 and the raised floor area.
Die Folie 9 kann außerdem in der Nähe der Seitenränder 8 oder 8' mit Ausnehmungen 14, 14' in Form von Löchern oder Ausstanzungen versehen sein, die dazu dienen, die Folie 9 allein oder zusammen mit dem geöffneten Papiersack 1 aufzuhängen, beispielsweise an einem Nagel oder einem Haken. Dies ist insbesondere dann vorteilhaft, wenn die Folie mit Anwendungshinweisen versehen ist, die dem Benutzer nach dem Ablösen vom Papiersack 1 Hilfestellungen für die Verwertung des Produkts geben können. Schließlich kann der erfindungsgemaße Papiersack 1 auf dem Deckblatt 5 des Standbodens 2 und/oder des Ventilbodens 3 einen Tragegriff aufweisen, der parallel zu dem Aufreißstreifen 6 verlauft, wobei dann, wenn der Tragegriff mittig auf dem Boden angeordnet ist, der Aufreißstreifen (6) in dem Fall nicht mittig zum Deckblatt (5, 5') verlauft. The film 9 can also be provided in the vicinity of the side edges 8 or 8 'with recesses 14, 14' in the form of holes or punch-outs which serve to hang the film 9 alone or together with the opened paper bag 1, for example on a nail or a hook. This is particularly advantageous if the film is provided with instructions for use, which can give the user after detachment from the paper bag 1 assistance for the utilization of the product. Finally, the inventive paper bag 1 on the cover sheet 5 of the base 2 and / or the valve base 3 have a carrying handle which runs parallel to the tear strip 6, wherein when the carrying handle is arranged centrally on the ground, the tear strip (6) in the case not centered to the cover sheet (5, 5 ') runs.
