Description

Die Erfindung betrifft einen Verpackungsbeutel mit Aufhängehaken, bestehend aus einem vorzugsweise wiederverschließbaren Beutel aus Kunststoff, der an seinem oberen Ende eine vorzugsweise als Handgriff ausgebildete Verlängerung aufweist, und einem Haken mit einem Hakenteil und einem als Rohr ausgebildeten Basisteil, das an seiner Unterseite einen Schlitz aufweist, mit dem es auf einen an der Verlängerung des Beutels vorgesehenen Wulst aufschiebbar ist.The invention relates to a packaging bag with hanging hook, consisting of a preferably resealable bag made of plastic, which has at its upper end an extension, preferably designed as a handle, and a hook with a hook part and a base part designed as a tube, which has a slot on its underside , with which it can be pushed onto a bead provided on the extension of the bag.

Ein derartiger Verpackungsbeutel ist aus der DE-C-21 42 623 bekannt. Der vorbekannte Verpackungsbeutel kann bei einfacher und billiger Herstellung ohne Abnehmen von seinem Haken geöffnet und geschlossen werden. Der Verschluß besteht aus einem Gleitverschluß aus Kunststoff.Such a packaging bag is known from DE-C-21 42 623. The known packaging bag can be opened and closed with simple and inexpensive manufacture without removing its hook. The closure consists of a slide closure made of plastic.

In der genannten Vorveröffentlichung ist in der Abbildung C ein Verpackungsbeutel mit einem Haken dargestellt, der einteilig aus einem Hakenteil und einem Basisteil ("Sockel") gespritzt ist. Das Basisteil ist als unten längs geschlitztes Rohr ("Stabilisierungsrohr") aus Kunststoff ausgebildet.In the aforementioned prior publication, a packaging bag with a hook is shown in Figure C, which is injection-molded in one piece from a hook part and a base part (“base”). The base part is a longitudinally slotted tube ("stabilizing tube") made of plastic.

Wie sich in der Praxis herausgestellt hat, ist ein derartiges Stabilisierungsrohr erforderlich, um dem aufgehängten Verpackungsbeutel die nötige Stabilität zu verleihen. Das Stabilisierungsrohr soll mindestens halb so lang sein wie der Beutel oder Sack breit ist, damit die Enden der Beutelöffnung durch das Gewicht der Füllung nicht heruntergezogen werden.As has been found in practice, such a stabilizing tube is required in order to give the suspended packaging bag the necessary stability. The stabilizing tube should be at least half as long as the bag or sack is wide so that the ends of the bag opening are not pulled down by the weight of the filling.

In den vergangenen Jahren hat sich allerdings die in der DE-C-21 42 623 in der Abbildung E gezeigte Ausführungsform zusammen mit einem Stabilisierungsrohr aus PVC (Polyvinylchlorid) als am besten geeignet bewährt. PVC bzw. Hart-PVC ist zum einen wegen seiner guten Stabilität besonders geeignet, zum anderen ist kein anderer Kunststoff so gut für diese Aufgabe bei einem vertretbaren Preis extrudierbar.In recent years, however, the embodiment shown in DE-C-21 42 623 in Figure E together with a stabilizing tube made of PVC (polyvinyl chloride) has proven to be the most suitable. On the one hand, PVC or hard PVC is particularly suitable because of its good stability, on the other hand, no other plastic can be extruded so well for this task at a reasonable price.

Der Nachteil der Ausführungsform gemäß Abbidlung E der DE-C-21 42 623 besteht allerdings darin, daß für den Haken zwei gesonderte Teile erforderlich sind, die gesondert gefertigt werden müssen und die in zwei Arbeitsgängen montiert werden müssen, wodurch hohe Lohnkosten verursacht werden. Hierbei ist zu beachten, daß hohe Lohnkosten immer mehr ins Gewicht fallen. Außerdem ist PVC nicht umweltfreundlich; es bereitet bei der Entsorgung zunehmend Schwierigkeiten.The disadvantage of the embodiment according to Fig. E of DE-C-21 42 623 is, however, that two separate parts are required for the hook, which have to be manufactured separately and which have to be assembled in two work steps, which causes high labor costs. It should be noted that high labor costs are becoming increasingly important. In addition, PVC is not environmentally friendly; it is becoming increasingly difficult to dispose of.

Um die hohen Lohnkosten herabzusetzen und aus Gründen des Umweltschutzes ist es demnach wünschenswert, den Haken, bestehend aus Hakenteil und Basisteil (Stabilisierungsrohr), aus einem Stück und aus einem leicht wiederverwertbaren (recycelbaren) Kunststoff zu fertigen. Ein derartiger Haken ist aus der DE-C-21 42 623 bereits bekannt, und zwar aus der oben erwähnten Abbildung C dieser Vorveröffentlichung. Er wurde auch getestet, hat sich in der Praxis allerdings aus folgenden Gründen nicht bewährt: Einerseits sollte das Basisteil des Hakens leicht und zügig auf die Wulst an der Verlängerung des Beutels aufgeschoben werden können. Zu diesem Zweck mußte der Schlitz an der Unterseite des Basisteils verhältnismäßig groß gemacht werden. Dann rutschte der Beutel allerdings auf der Wulst der Verlängerung hin und her. Wenn andererseits der Schlitz enger gemacht wurde, um ein Verrutschen des Beutels zu verhindern, war die Verlängerung des Beutels nur sehr schwer aufschiebbar, die Montage also mit zu großen Schwierigkeiten verbunden.In order to reduce the high labor costs and for reasons of environmental protection, it is therefore desirable to manufacture the hook, consisting of the hook part and base part (stabilizing tube), from one piece and from an easily recyclable (recyclable) plastic. Such a hook is already known from DE-C-21 42 623, namely from the above-mentioned Figure C of this prior publication. It has also been tested, but has not proven itself in practice for the following reasons: On the one hand, the base part of the hook should be pushed onto the bead on the extension of the bag quickly and easily can. For this purpose, the slot on the underside of the base part had to be made relatively large. Then the bag slid back and forth on the bulge of the extension. If, on the other hand, the slot was made narrower to prevent the bag from slipping, the extension of the bag was very difficult to slide open, and assembly was therefore extremely difficult.

Um das Hin- und Herrutschen des Hakens auf der Wulst der Verlängerung des Beutels zu verhindern, sind verschiedene Maßnahmen versucht worden. Man hat z.B. im Bereich des Grifflochs in der Verlängerung eine oder mehrere Laschen angespritzt, die dann durch das Griffloch hindurch umgelegt und druckknopfartig eingeknipst werden konnten. Die Montage ist dann allerdings sehr schwierig und zeitaufwendig und damit teuer. Es wurde auch der Versuch unternommen, den aufgeschobenen Haken mit einer Zange und einer Miete zu befestigen, was allerdings ebenfalls umständlich und teuer ist. Weiterhin könnte der aufgeschobene Haken mittels einer Schweißzange punktförmig unterhalb der Wulst an der Verlängerung oder am Steg des Gleitverschlußbandes befestigt werden. Auch diese Maßnahme scheitert am zu hohen Arbeitsaufwand und damit an den zu hohen Lohnkosten.Various measures have been attempted to prevent the hook from sliding back and forth on the bead of the extension of the bag. You have e.g. In the area of the grip hole in the extension, one or more tabs were molded on, which could then be folded through the grip hole and snapped in like a push button. The assembly is then very difficult and time-consuming and therefore expensive. Attempts have also been made to fix the slid-on hook with pliers and a rent, but this is also cumbersome and expensive. Furthermore, the slid-on hook could be attached to the extension or to the web of the slide fastener tape at a point below the bead by means of welding tongs. This measure also fails due to the high workload and thus the high wage costs.

Aufgabe der Erfindung ist es, einen Verpackungsbeutel mit Aufhängehaken der eingangs angegebenen Art zu schaffen, bei dem das als Rohr ausgebildete Basisteil des Hakens leicht auf die Wulst der Verlängerung des Beutels aufgeschoben werden kann und bei dem das Basisteil in der aufgeschobenen Stellung nicht verrutschen kann.The object of the invention is to provide a packaging bag with hanging hooks of the type mentioned, in which the base part of the hook, which is designed as a tube, can be easily pushed onto the bead of the extension of the bag and in which the base part cannot slip in the pushed-on position.

Gemäß der Erfindung wird diese Aufgabe nach dem Kennzeichnungsteil des Anspruchs 1 dadurch gelöst, daß an dem Basisteil mindestens ein Nocken vorgesehen ist, der in eine Ausnehmung in dem Beutel eingreift. Der mindestens eine Nocken ist vorzugsweise an der Unterseite des Basisteils vorgesehen. Der Nocken kann an dem Basisteil angespritzt sein, also mit dem Basisteil einstückig verbunden sein. Bei der neuerungsgemäßen Lösung ist es möglich, den Schlitz in dem Basisteil verhältnismäßig groß auszubilden, so daß das Basisteil leicht aufgeschoben werden kann. Das Basisteil wird nach der Montage durch den in die Ausnehmung eingreifenden Nocken zuverlässig festgehalten, also gegen Verrutschen gesichert.According to the invention, this object is achieved according to the characterizing part of claim 1 in that at least one cam is provided on the base part, which engages in a recess in the bag. The at least one cam is preferably provided on the underside of the base part. The cam can be injection molded onto the base part, ie in one piece with the base part be connected. In the solution according to the innovation, it is possible to make the slot in the base part relatively large, so that the base part can be easily pushed open. After assembly, the base part is reliably held in place by the cams engaging in the recess, that is to say secured against slipping.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.

Vorzugsweise verläuft der Nocken von einer Seite an der Unterseite des Basisteils derart schräg nach unten, daß er über den Schlitz des Basisteils hinausragt. Der Nocken ragt also unterhalb des Schlitzes in die Ebene des Schlitzes hinein. Bei der Montage muß der Beutel bzw. dessen Verlängerung im Bereich der Wulst etwas weggebogen werden. Dies bereitet allerdings aufgrund der Elastizität des Beutels bzw. der Verlängerung des Beutels keine großen Schwierigkeiten. In der Endstellung wird der Beutel dann losgelassen, so daß dessen Verlängerung aufgrund ihrer Eigenelastizität von selbst in die Ebene des Schlitzes gelangt.Preferably, the cam extends obliquely downwards from one side on the underside of the base part such that it projects beyond the slot of the base part. The cam therefore projects below the slot into the plane of the slot. During assembly, the bag or its extension must be bent slightly away in the area of the bead. However, due to the elasticity of the bag or the lengthening of the bag, this does not pose any great difficulties. In the end position, the bag is then released, so that its extension, due to its inherent elasticity, automatically reaches the plane of the slot.

Nach einer weiteren vorteilhaften Weiterbildung ist die Ausnehmung rechteckig bzw. vierkantig. Hierdurch wird der vorzugsweise entsprechend ausgebildete Nocken besonders zuverlässig festgehalten.According to a further advantageous development, the recess is rectangular or square. As a result, the preferably appropriately designed cam is held particularly reliably.

Die Ausnehmung kann in die Verlängerung eingestanzt sein. Diese Ausführungsform ist besonders einfach herstellbar. Wenn - wie üblich - in der Verlängerung des Beutels eine Griffausnehmung vorhanden ist, beträgt der Abstand der Ausnehmung von der Griffausnehmung vorzugsweise mindestens 5 mm.The recess can be punched into the extension. This embodiment is particularly easy to manufacture. If - as usual - there is a handle recess in the extension of the bag, the distance of the recess from the handle recess is preferably at least 5 mm.

Nach einer weiteren vorteilhaften Weiterbildung wird die Ausnehmung von der seitlichen Begrenzung einer in der Verlängerung vorgesehenen Griffausnehmung gebildet. Gesonderte Ausnehmungen sind dann nicht erforderlich.According to a further advantageous development, the recess is formed by the lateral boundary of a handle recess provided in the extension. Separate recesses are then not necessary.

Grundsätzlich ist ein Nocken und damit auch eine Ausnehmung ausreichend. Aus Gründen der Funktionssicherheit, insbesondere deshalb, um beim Transport oder Herumwerfen der Verpackungsbeutel ein Verschieben zu vermeiden, sind allerdings vorzugsweise zwei oder mehr Nocken vorgesehen. Die Nocken können von derselben Seite her in die zugehörigen Ausnehmungen eingreifen. Es ist aber auch möglich, daß die Nocken von gegenüberliegenden Seiten her in die zugehörigen Ausnehmungen eingreifen. Dadurch ist eine noch sicherere Befestigung des Hakens auf der Verlängerung gewährleistet. Bei auf verschiedenen Seiten liegenden Ausnehmungen ergibt sich der Nachteil, daß die Montage des Hakens dadurch erschwert wird, daß die Verlängerung während der Montage abwechslungsweise nach der einen und nach der anderen Seite weggedrückt werden muß. Dasselbe gilt für die Demontage des Hakens. Dieser geringfügige Nachteil kann allerdings für die verbesserte Funktionssicherheit in Kauf genommen werden.Basically, a cam and thus a recess is sufficient. For reasons of functional safety, in particular in order to avoid displacement during transport or tossing around the packaging bag, two or more cams are preferably provided, however. The cams can engage in the corresponding recesses from the same side. But it is also possible that the cams engage from opposite sides in the associated recesses. This ensures an even more secure attachment of the hook to the extension. In the case of recesses lying on different sides, there is the disadvantage that the assembly of the hook is made more difficult by the fact that the extension has to be pressed alternately to one side and to the other during assembly. The same applies to dismantling the hook. However, this slight disadvantage can be accepted for improved functional reliability.

Nach einer weiteren vorteilhaften Weiterbildung weist der Schlitz des Basisteils an seinen Enden eine trichterförmige Erweiterung auf, um das Aufschieben des Basisteils des Hakens zu erleichtern.According to a further advantageous development, the slot of the base part has a funnel-shaped extension at its ends in order to make it easier to slide on the base part of the hook.

Der in der Fig. 1 gezeigte Verpackungsbeutel besteht aus einem Beutel 2 und einem Haken 16. Der Beutel 2 aus Kunststoff ist durch einen Gleitverschluß 17 verschließbar. Er weist an seinem oberen Ende eine Verlängerung 14 auf, die auch als Steg bezeichnet werden kann. Die Verlängerung 14 kann mit einem der Bänder des Gleitverschlusses 17 einstückig verbunden sein. In der Verlängerung 14 ist eine Griffausnehmung (Handgriff) 18 vorhanden.The packaging bag shown in FIG. 1 consists of a bag 2 and a hook 16. The plastic bag 2 can be closed by a slide closure 17. It has an extension 14 at its upper end, which can also be referred to as a web. The extension 14 can be connected in one piece to one of the bands of the slide closure 17. In the extension 14 there is a handle recess (handle) 18.

Der Haken 16 besteht aus einem Hakenteil 15 und einem als Rohr ausgebildeten Basisteil 1. An der Unterseite des Basisteils 1 ist ein Schlitz 8 vorhanden, mit dem das Basisteil 1 auf eine am oberen Ende der Verlängerung 14 vorgesehene Wulst 9 aufgeschoben werden kann.The hook 16 consists of a hook part 15 and a base part 1 in the form of a tube. A slot 8 is provided on the underside of the base part 1, with which the base part 1 can be pushed onto a bead 9 provided at the upper end of the extension 14.

An dem in der Fig. 1 gezeigten Basisteil 1 sind zwei Nocken vorgesehen, die in die Ausnehmungen 3, 4 in der Verlängerung 14 eingreifen. Wie aus Fig. 3 ersichtlich, verlaufen die Nocken 5 von einer Seite an der Unterseite des Basisteils 1 derart schräg nach unten, daß sie über den Schlitz 8 des Basisteils 1 hinausragen. Durch die beiden Nocken 5, die an das als Stabilisierungsrohr ausgebildete Basisteil 1 angespritzt sind, wird das Basisteil 1 und damit der gesamte Haken, bestehend aus Hakenteil 15, Basisteil 1 und Nocken 5, in der Weise festgehalten, daß die beiden Nocken 5 in die beiden vierkantigen Ausnehmungen 3, 4 einrasten. Die vierkantigen Ausnehmungen 3, 4 sind an der Verlängerung 2 unterhalb der Wulst 9 vorgesehen. Eine Hin- und Herbewegung des aufgeschobenen Hakens 16 wird damit zuverlässig verhindert.On the base part 1 shown in FIG. 1, two cams are provided which engage in the recesses 3, 4 in the extension 14. As can be seen from FIG. 3, the cams 5 run from one side on the underside of the base part 1 so that they protrude beyond the slot 8 of the base part 1. By the two cams 5, which are injection molded onto the base part 1 designed as a stabilizing tube, the base part 1 and thus the entire hook, consisting of hook part 15, base part 1 and cams 5, are held in such a way that the two cams 5 enter into the engage the two square recesses 3, 4. The square recesses 3, 4 are provided on the extension 2 below the bead 9. A back and forth movement of the pushed-on hook 16 is thus reliably prevented.

Die vorzugsweise vierkantigen Ausnehmungen 3, 4 können auf verschiedene Weise in die Verlängerung 14 eingestanzt werden. Beispielsweise können sie - wie in Fig. 1 dargestellt - links und rechts von der Griffausnehmung 18 angebracht werden, wobei der Abstand von der Griffausnehmung 18 vorzugsweise mindestens 5 mm beträgt. Dadurch entsteht eine sehr gute Stabilität gegen das Herausrutschen der Nocken 5 aus den Ausnehmungen 3, 4.The preferably square recesses 3, 4 can be punched into the extension 14 in various ways. For example, as shown in FIG. 1, they can be attached to the left and right of the handle recess 18, the distance from the handle recess 18 preferably being at least 5 mm. This creates very good stability against the cams 5 slipping out of the recesses 3, 4.

Man kann aber die Nocken auch unmittelbar an beiden Enden der Griffausnehmung 18 anbringen. Dies ist in der Fig. 2 dargestellt. Um eine besonders zuverlässige Arretierung zu erreichen, weist die Griffausnehmung 18 an den oberen, der Wulst 9 zugewandten Enden ihrer äußeren Rundungen 19 jeweils eine kurze gerade Kante 6, 7 auf. Die Ausnehmungen 3, 4 werden dann von den seitlichen Begrenzungen der Griffausnehmung 18 gebildet.But you can also attach the cams directly to both ends of the handle recess 18. This is shown in FIG. 2. In order to achieve a particularly reliable locking, the handle recess 18 has a short straight edge 6, 7 at the upper ends of its outer curves 19 facing the bead 9. The recesses 3, 4 are then formed by the lateral boundaries of the handle recess 18.

Das als Stabilisierungsrohr ausgebildete, mit Nocken (Haken) 5 versehene Basisteil läßt sich leicht und rutschsicher mit einem Handgriff montieren. Es kann bei der späteren Entsorgung ebenfalls ganz leicht durch Wegbiegen der Verlängerung wieder abgetrennt werden. Die Verlängerung 14 wird von den Nocken 5 (in der Fig. 3 nach rechts) weggebogen, so daß die Nocken 5 außer Eingriff gelangen. Dann kann das Basisteil 1 und mit ihm der gesamte Haken 16 einfach abgezogen werden. Sowohl beim Aufschieben des Hakens 16 als auch beim Abziehen ist kein nennenswerter Widerstand zu überwinden, wenn die Verlängerung von den Nocken weg zur Seite gedrückt wird.The base part, which is designed as a stabilizing tube and is provided with cams (hooks) 5, can be mounted easily and in a non-slip manner with one hand. It can also be easily removed for later disposal by bending the extension away. The extension 14 is bent away from the cams 5 (to the right in FIG. 3) so that the cams 5 disengage. Then the base part 1 and with it the entire hook 16 can simply be pulled off. There is no appreciable resistance to overcome, either when the hook 16 is pushed on or when it is pulled off, if the extension is pushed aside by the cams.

Wegen der notwendigen Steifigkeit wird der Haken 16 vorzugsweise aus dem Kunststoff Polypropylen hergestellt, und zwar vorzugsweise als einstückiges Teil, bestehend aus Hakenteil 15, Basisteil 1 und Nocken 5. Der Kunststoff Polypropylen ist wiederverwendbar (recyelbar), ebenso wie Polyäthylen, aus dem die überwiegende Masse der Beutel und Säcke hergestellt ist. Es versteht sich, daß auch jeder andere geeignete Kunststoff einsetzbar ist.Because of the necessary rigidity, the hook 16 is preferably made of the plastic polypropylene, and preferably as a one-piece part, consisting of the hook part 15, base part 1 and cams 5. The plastic polypropylene is reusable (recyclable), as is polyethylene, from which the predominant Mass of bags and sacks is made. It goes without saying that any other suitable plastic can also be used.

Die beiden Nocken 5 greifen vorzugsweise von einer Seite her schräg nach unten in die Ausnehmungen, wie dies in der Fig. 3 dargestellt ist. Sie stehen über den Schlitz 8 des Basisteils 1 hinaus, und zwar so weit, daß sie nach dem Loslassen der weggebogenen Verlängerung 14 des Beutels bzw. des Tragegleitverschlußbandes 2 von selbst satt in die Ausnehmungen einrasten.The two cams 5 preferably engage obliquely downwards from one side into the recesses, as is shown in FIG. 3. They protrude beyond the slot 8 of the base part 1, to the extent that, after releasing the bent extension 14 of the bag or of the carrying slide fastener tape 2, they automatically snap into the recesses.

Grundsätzlich genügt eine Nocke und eine Ausnehmung. Aus Gründen der Funktionssicherheit, insbesondere deshalb, um beim Transport oder Herumwerfen der Packungen ein Verschieben der Nocken zu vermeiden, sind allerdings vorzugsweise zwei Nocken und zwei Ausnehmungen vorgesehen.Basically, a cam and a recess are sufficient. For reasons of functional reliability, in particular in order to prevent the cams from shifting when the packs are being transported or thrown around, two cams and two recesses are preferably provided.

Nach der in der Fig. 4 dargestellten Alternative greift eine Nocke 10 von der einen Seite und eine zweite Nocke 11 von der gegenüberliegenden Seite des Schlitzes 8 bzw. der Verlängerung 14 in entsprechende Ausnehmungen ein. Dadurch ist eine noch sicherere Befestigung des Hakens 16 auf der Verlängerung 14 gewährleistet. Allerdings hat diese Art der Befestigung den Nachteil, daß die Montage des Schiebehakens 16 dadurch erschwert wird, daß die Verlängerung 14 abwechselungsweise nach der einen und nach der anderen Seite weggedrückt werden muß. Das gleiche gilt für die Demontage des Hakens. Diesem Nachteil steht jedoch der Vorteil gegenüber, daß der Haken 16 sicherer befestigt und gegen Verschieben gesichert ist.According to the alternative shown in FIG. 4, a cam 10 engages from one side and a second cam 11 from the opposite side of the slot 8 or the extension 14 in corresponding recesses. This ensures an even more secure attachment of the hook 16 on the extension 14. However, this type of attachment has the disadvantage that the assembly of the sliding hook 16 is made more difficult by the fact that the extension 14 has to be pressed alternately to one side and the other. The same applies to dismantling the hook. However, this disadvantage is offset by the advantage that the hook 16 is secured more securely and secured against displacement.

Der Schlitz 8 des aufzuschiebenden Basisteils 1 des Hakens 16 wird derart eng ausgeführt, daß die Wulst 9 auch bei großer Belastung des Beutels nicht aus dem Basisteil 1 herausrutscht. Der Schlitz 8 besteht dementsprechend aus einem unteren, engeren Teil und einer Erweiterung 12, die die Wulst 9 aufnimmt.The slot 8 of the base part 1 of the hook 16 to be pushed open is made so narrow that the bead 9 does not slip out of the base part 1 even when the bag is subjected to great stress. Accordingly, the slot 8 consists of a lower, narrower part and an extension 12 which receives the bead 9.

Um das Aufschieben des Hakens 16 mit Basisteil 1 zu erleichtern, ist an beiden Enden des als Stabilisierungsrohr ausgebildeten Basisteils 1 eine kurze trichterförmige Erweiterung 13 vorgesehen, die in der Fig. 5 dargestellt ist.In order to facilitate the pushing on of the hook 16 with the base part 1, a short funnel-shaped extension 13 is provided at both ends of the base part 1, which is designed as a stabilizing tube and is shown in FIG. 5.
