Abstract

The invention relates to a mailing bag made of corrugated cardboard which has a closure flap which can be folded over a joint line (6) onto the front (2) and can be inserted in a slot (7) in the front wall. The closure flap consists of corrugated cardboard which is open on one side. In the inserted state, the corrugation crests (5) of the open side of the closure flap point towards the rear wall (3) and extend substantially transversely to the insertion direction of the closure flap. The slot (7) in the front runs parallel to the corrugation crests (5) so that, in the inserted state of the closure flap, in each case one of the corrugation crests engages in a positive-locking manner behind one of the slot edges (9) in the manner of a snap-on catch. In this mailing bag, a secure closure of the mailing bag is provided solely from the material used for the mailing bag without additional aids or adhesives having to be used. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Versandtasche aus Wellpappe, mit einer im wesentlichen rechteckigen Vorderwand und einer zugehörigen Rückwand, die an drei ihrer Ränder mit der Vorderwand fest verbunden ist und eine um eine Gelenklinie auf die Vorderwand klappbare Verschlußlasche aufweist, die in einen Schlitz in der Vorderwand einsteckbar ist.The invention relates to a mailing bag made of corrugated cardboard, with a substantially rectangular front wall and an associated rear wall, which is firmly connected to the front wall at three of its edges and has a closure flap which can be folded about an articulated line onto the front wall and which fits into a slot in the front wall Front wall is insertable.

Aus der Praxis sind Versandtaschen vielfältiger Art bekannt. Sie ermöglichen den Versand von Dokumenten und Kleinteilen als Briefpost. Für den Versand druckempfindlicher Kleinteile haben sich Versandtaschen bewährt, die im Inneren mit einer sogenannten Luftpolsterfolie ausgekleidet sind. Nachteilig an diesen Versandtaschen ist jedoch, daß diese aus zwei unterschiedlichen Materialien, nämlich Pappe und Kunststoff, bestehen, was die geordnete Entsorgung der Versandtasche nach ihrem Gebrauch erschwert.Mailers of various types are known in practice. They enable documents and small parts to be sent as mail. For the dispatch of pressure-sensitive small parts, dispatch pockets have been found to be effective, which are lined with a so-called bubble wrap on the inside. A disadvantage of these mailers, however, is that they consist of two different materials, namely cardboard and plastic, which complicates the orderly disposal of the mailer after use.

Darüber hinaus gibt es auch bereits Versandtaschen aus Wellpappe, die ebenfalls für den Versand empfindlicher Teile geeignet sind, da die Wellpappe ebenfalls in der Lage ist, Stöße abzumildern. Bei diesen Versandtaschen besteht das Problem, daß der Verschluß in aller Regel aufwendig gestaltet werden muß, falls man nicht auf Kunststoffklebestreifen zurückgreifen will, die die Entsorgung der Versandtaschen wieder erschweren. Im übrigen wird für den Versand von Drucksachen oder Büchern eine Wiederverschließbarkeit der Versandtasche gefordert, die sich mit Klebestreifen in aller Regel nicht erreichen läßt.In addition, there are also corrugated cardboard shipping bags that are also suitable for shipping sensitive parts, since corrugated cardboard is also able to mitigate impacts. The problem with these mailing bags is that the closure generally has to be designed in a complex manner if one does not want to use plastic adhesive strips which make it difficult to dispose of the mailing bags again. In addition, the mailing bag is required to be resealable for the dispatch of printed matter or books, which, as a rule, cannot be achieved with adhesive strips.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Versandtasche der eingangs genannten Art so weiterzubilden, daß diese sich auf einfache Weise verschließen und nach einem Öffnen auch wiederverschließen läßt.It is therefore an object of the present invention to develop a mailing bag of the type mentioned at the outset in such a way that it can be closed in a simple manner and can also be resealed after opening.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verschlußlasche aus einseitig offener Wellpappe besteht, wobei die Wellenberge der offenen Seite der Verschlußlasche in deren eingestecktem Zustand zur Rückwand weisen und sich im wesentlichen quer zur Steckrichtung der Verschlußlasche erstrecken, und daß der Schlitz parallel zu den Wellenbergen verläuft, so daß im eingesteckten Zustand der Verschlußlasche jeweils einer der Wellenberge einen der Schlitzränder nach Art einer Schnappraste formschlüssig hintergreift.This object is achieved in that the closure flap consists of corrugated cardboard which is open on one side, the wave crests of the open side of the closure flap pointing in the inserted state to the rear wall and extending essentially transversely to the direction of insertion of the closure flap, and that the slot parallel to the corrugation crests runs so that in the inserted state of the locking tab one of the wave crests engages behind one of the slot edges in the manner of a snap catch.

Bei dieser Lösung üben die Wellenberge der einseitig offenen Wellpappe eine Doppelfunktion aus. Sie dienen nunmehr nicht nur zur Stoßabsorbierung, sondern übernehmen gleichzeitig die Funktion von Schnapprasten, die eine stufenweise Arretierung der Verschlußlasche in dem Schlitz gestatten, so daß die Versandtasche auch bei unterschiedlich starker Füllung stets sicher verschlossen werden kann. Da die Wellenberge eine gewisse Elastizität aufweisen, ist das Herausziehen der Verschlußlasche von Hand möglich, ohne daß die Wellenberge dabei zerstört werden. Diese Eigenschaft der Wellpappe gestattet eine Wiederverwendung der Versandtasche.With this solution, the crests of the corrugated cardboard, which is open on one side, have a dual function. They now serve not only for shock absorption, but at the same time take on the function of snap catches, which allow a gradual locking of the locking tab in the slot, so that the mailing bag can always be securely closed even with different filling levels. Since the wave crests have a certain elasticity, the closure flap can be pulled out by hand without the wave crests being destroyed in the process. This property of the corrugated cardboard allows the mailing bag to be reused.

Obgleich die Wellenberge auch schräg verlaufen können, solange nur der Schlitz parallel zu den Wellenbergen der Verschlußlasche verläuft, wird bevorzugt, wenn die Wellenberge parallel zur Gelenklinie der Verschlußlasche verlaufen.Although the wave crests can also run obliquely as long as only the slot runs parallel to the wave crests of the closure flap, it is preferred if the wave crests run parallel to the hinge line of the closure flap.

Die Verschließeigenschaften der Versandtasche lassen sich dadurch noch weiter verbessern, daß der dem offenen Ende der Versandtasche zugewandte Schlitzrand, der von den Wellenbergen der Verschlußlasche hintergriffen ist, durch eine gestanzte, in der Ebene der Vorderwand liegende Federlasche gebildet ist, die zumindest so breit ist wie die einsteckbare Verschlußlasche. Diese Federlasche wird beim Einstecken der Verschlußlasche in den Schlitz leicht nach unten gebogen und drückt aufgrund der federelastischen Eigenschaften der Wellpappe nach oben gegen den jeweiligen Wellenberg, der sich an dem durch die Federlasche gebildeten Rand des Schlitzes abstützt.The sealing properties of the mailing bag can be further improved in that the slot edge facing the open end of the mailing bag, which is engaged by the wave crests of the sealing flap, is formed by a stamped spring clip lying in the plane of the front wall, which is at least as wide as the insertable locking tab. This spring tab is bent slightly downwards when the closure tab is inserted into the slot and, due to the elastic properties of the corrugated cardboard, presses upwards against the respective crest of the wave which is supported on the edge of the slot formed by the spring tab.

Das Einführen der Verschlußlasche in den Schlitz läßt sich auf einfache Weise dadurch erleichtern, daß der andere Schlitzrand wannenförmig verläuft und an die Ausstanzung der Federlasche angrenzt, wobei die beiden Schlitzränder im wannenförmigen Bereich einen lichten Abstand voneinander aufweisen, und wobei ferner der lichte Abstand der Wannenränder kleiner ist als die Breite der Verschlußlasche. Dadurch läßt sich die Verschlußlasche zwar einerseits leicht in den Schlitz einführen; da die Verschlußlasche im eingeführten Zustand jedoch breiter ist als der lichte Abstand der Wannenränder des Schlitzes, wird die Verschlußlasche in den Bereich des Schlitzes eingezogen, der nur noch aus der Ausstanzung der Federlasche besteht, wodurch die Verschlußlasche in diesem Bereich fest an den durch die Federlasche gebildeten Schlitzrand angedrückt wird.The insertion of the closure flap into the slot can be facilitated in a simple manner in that the other slot edge is trough-shaped and adjoins the punching of the spring clip, the two slot edges being spaced apart from one another in the trough-shaped region, and furthermore the clear distance between the trough edges is smaller than the width of the locking tab. As a result, the locking tab can be easily inserted into the slot on the one hand; however, since the closure flap is wider than the clear distance between the trough edges of the slot in the inserted state, the closure flap is drawn into the area of the slot which only consists of the punched-out spring flap, whereby the closure flap in this area is firmly attached to the through the spring flap formed slot edge is pressed.

In günstiger Weise kann die Ausstanzung der Federlasche an deren seitlichen Rändern kreisbogenförmig enden. Das hat den Vorteil, daß auch bei mehrfacher Benutzung der Versandtasche, d.h. bei mehrfachem Einstecken und Herausziehen der Verschlußlasche, die Federlasche an ihren seitlichen Rändern nicht ausreißt.The punching of the spring tab can end in a circular arc at its lateral edges in a favorable manner. This has the advantage that even if the mailing bag is used several times, ie if the closure tab is inserted and pulled out several times, the spring tab does not tear at its lateral edges.

Die Herstellung der Versandtasche läßt sich in bevorzugter Weise dadurch vereinfachen, daß die gesamte Versandtasche aus einem einstückigen Zuschnitt aus einseitig offener Wellpappe besteht, wobei die geschlossene Seite der Wellpappe nach außen weist. Der Begriff "einseitig offene Wellpappe" bedeutet im Zusammenhang mit der Erfindung, daß eine Wellpappe verwendet wird, deren eine Seite glatt ausgebildet ist (geschlossene Seite) und deren andere Seite gewellt ausgebildet ist (offene Seite).The manufacture of the mailing bag can be simplified in a preferred manner in that the entire mailing bag consists of a one-piece blank made of corrugated cardboard which is open on one side, the closed side of the corrugated cardboard pointing outwards. In connection with the invention, the term “corrugated cardboard open on one side” means that corrugated cardboard is used whose one side is smooth (closed side) and the other side is corrugated (open side).

Die Versandtasche 1 besteht aus einem einteiligen Zuschnitt mit einer Vorderwand 2, einer Rückwand 3 und einer mit der Rückwand 3 über eine Gelenklinie 6 schwenkbar verbundene Verschlußlasche 4. Das Material des Zuschnittes ist eine einseitig offene Wellpappe, d.h. eine Pappe, die aus einer glatten Lage (geschlossene Seite) und einer gewellten Lage (offene Seite) besteht. Die Wellenberge 5 sind in Fig. 5 durch parallele Linien und in den Fig. 2 bis 4 durch Wellen angedeutet. Die Wellenberge 5 erstrecken sich bei dem hier dargestellten Ausführungsbeispiel parallel zu der Gelenklinie 6.The mailing bag 1 consists of a one-piece blank with a front wall 2, a rear wall 3 and a closure flap 4 which is pivotally connected to the rear wall 3 via an articulated line 6. The material of the blank is a corrugated cardboard open on one side, ie a cardboard made from a smooth layer (closed Side) and a corrugated layer (open side). The wave crests 5 are indicated in FIG. 5 by parallel lines and in FIGS. 2 to 4 by waves. In the exemplary embodiment shown here, the wave crests 5 extend parallel to the joint line 6.

Auf der Vorderseite 2 der Versandtasche 1 ist ein Schlitz 7 vorgesehen, der zum Einstecken der Verschlußlasche 4 dient. Der Schlitz 7 wird durch zwei Schlitzränder 9 und 10 begrenzt. Der Schlitzrand 9 wird durch eine ausgestanzte Federlasche 8 gebildet. Die Ausstanzung 12 der Federlasche 8 endet beidseitig kreisbogenförmig, um das Einreißen der Federlasche zu vermeiden. Wie aus Fig. 5 ersichtlich, ist die Breite c der Federlasche 8 größer als die Breite b der Verschlußlasche 4. Der andere Schlitzrand 10 ist wannenförmig ausgebildet und weist einen lichten Abstand zum Schlitzrand 9 auf. Seitlich wird der Schlitzrand 9 durch Wannenränder 11 begrenzt, die in die Ausstanzung 12 der Federlasche 8 auslaufen. Der lichte Abstand a der Wannenränder 11 ist kleiner als die Breite b der Verschlußlasche 4. Nachzutragen bleibt noch, daß die seitlichen Ränder der Vorderwand 2 und der Rückwand 3 der Versandtasche 1 durch Kleben miteinander verbunden sind.On the front 2 of the mailing bag 1, a slot 7 is provided, which is used to insert the closing flap 4. The slot 7 is delimited by two slot edges 9 and 10. The slot edge 9 is formed by a punched-out spring tab 8. The punching 12 of the spring tab 8 ends in a circular arc on both sides to avoid tearing the spring tab. As can be seen from FIG. 5, the width c of the spring tab 8 is larger than the width b of the closure tab 4. The other slot edge 10 is trough-shaped and has a clear distance from the slot edge 9. Laterally, the slot edge 9 is delimited by trough edges 11 which run into the punched-out portion 12 of the spring tab 8. The clear distance a of the tub edges 11 is smaller than the width b of the closure flap 4. It remains to be added that the side edges of the front wall 2 and the rear wall 3 of the mailing bag 1 are connected to one another by gluing.

Im folgenden wird nun die Wirkungs- und Funktionsweise der Erfindung näher erläutert.The operation and functioning of the invention will now be explained in more detail below.

Ausgehend von der Schnittdarstellung in Fig. 2 wird die Verschlußlasche 4 nun in den Schlitz 7 eingesteckt, wobei die Verschlußlasche 4 zunächst in den wannenförmig ausgestanzten Bereich eintaucht. Je weiter man die Verschlußlasche 4 in den Schlitz hineinschiebt, werden deren Ränder jedoch durch die Wannenränder 11 in den Bereich des Schlitzes gedrückt, der nur noch aus der Ausstanzung 12 besteht. Dadurch wird die Federlasche 8 geringfügig aus der Ebene der Vorderwand 2 nach unten gedrückt. Aufgrund der federelastischen Eigenschaften drückt der von der Federlasche 8 gebildete Schlitzrand 9 in die Wellentäler benachbarter Wellenberge 5, was zu einer Verrastung der Verschlußlasche 4 mit dem Schlitz 7 führt.Starting from the sectional view in FIG. 2, the locking tab 4 is now inserted into the slot 7, the locking tab 4 first being immersed in the trough-shaped area. The further one pushes the locking tab 4 into the slot, the edges of which are pressed by the tub edges 11 into the area of the slot which only consists of the punched-out portion 12. As a result, the spring tab 8 is slightly down from the plane of the front wall 2 pressed. Due to the resilient properties, the slot edge 9 formed by the spring tab 8 presses into the troughs of adjacent wave crests 5, which leads to a locking of the closure tab 4 with the slot 7.

Das Herausziehen der Verschlußlasche 4 zum Öffnen der Versandtasche 1 geschieht in umgekehrter Reihenfolge. Das Herausziehen kann dadurch erleichtert werden, daß man die Federlasche 8 aus der Ebene der Vorderwand 2 heraus weiter nach unten drückt. Aufgrund der elastischen Eigenschaften der Wellpappe kann man die Verschlußlasche 4 jedoch auch ohne Zerstörung des Verschlusses so herausziehen, wenn man nur kräftig genug daran zieht. Da der Verschluß zerstörungsfrei geöffnet werden kann, kann die Versandtasche mehrmals wiederverwendet werden. Im übrigen besteht die gesamte Versandtasche aus einem einzigen Material und ist daher in besonderem Maße recyclingfähig.The pulling out of the closure flap 4 for opening the mailing bag 1 takes place in the reverse order. Pulling it out can be facilitated by pushing the spring tab 8 further down from the plane of the front wall 2. Due to the elastic properties of the corrugated cardboard, the closure flap 4 can be pulled out without destroying the closure, however, if one pulls it only sufficiently. Since the closure can be opened non-destructively, the mailing bag can be reused several times. In addition, the entire mailing bag is made of a single material and is therefore particularly recyclable.

Obwohl bei dem hier gezeigten Ausführungsbeispiel die Wellenberge parallel zur Gelenklinie der Verschlußlasche verlaufen, ist es auch denkbar, wenn die Wellenberge schräg zur Gelenklinie verlaufen. Wichtig ist jedoch, daß dann auch der Einsteckschlitz für die Verschlußlasche schräg verläuft, so daß die Wellenberge der Verschlußlasche mit dem zugehörigen Schlitzrand verrasten können. Eine solche Ausbildung kann vorzugsweise dann Anwendung finden, wenn zur Aussteifung der Versandtasche die Wellenberge in etwa diagonal verlaufen sollen.Although in the embodiment shown here the wave crests run parallel to the hinge line of the locking tab, it is also conceivable if the wave crests run obliquely to the hinge line. It is important, however, that the insertion slot for the closure flap then also runs obliquely, so that the wave crests of the closure flap can latch with the associated slot edge. Such a design can preferably be used if the wave crests are to run approximately diagonally to stiffen the mailing bag.
