Description

Die vorliegende Erfindung betrifft einen auf den Hals eines Kunststoffbehälters aufschraubbaren Kunststoffverschluß mit einem Schraubring und mit einem Einsatzteil mit flexiblem Balg und einem Ausgießer, auf dessen Außengewinde eine Kappe aufschraubbar ist, wobei die Kappe mit dem Schraubring einstük­kig ausgebildet ist und die Kopfwand der Bügelkappe im Abstand von der Kopfwand des Schraubringes herausstehend angeformt ist. Ein solcher Kunststoffverschluß ist in der deutschen Patentan­meldung Nr. 37 20 225.6 beschrieben, zu welcher die vorliegen­de Anmeldung in einem Zusatzverhältnis steht. Auf die Diskus­sion des Standes der Technik und die daraus abgeleitete Aufga­benstellung in der DE-OS 37 30 225.6 wird insoweit ausdrücklich Bezug genommen.The present invention relates to a plastic closure that can be screwed onto the neck of a plastic container, with a screw ring and with an insert part with a flexible bellows and a spout, on the external thread of which a cap can be screwed, the cap being designed in one piece with the screw ring and the head wall of the clip cap at a distance protruding from the top wall of the screw ring. Such a plastic closure is described in German Patent Application No. 37 20 225.6, to which the present application has an additional relationship. In this respect, reference is expressly made to the discussion of the prior art and the task derived therefrom in DE-OS 37 30 225.6.

Auch der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen auf den Hals eines Kunststoffbehälters aufschraubbaren Kunststoffverschluß mit Schraubring und mit einem Einsatzteil mit flexiblem Balg und Ausgießer, auf dessen Außengewinde eine Kappe aufschraubbar ist, so zu verbessern, daß unter Beibehal­tung guter Ausgießeigenschaften, z.B. mittels eines flexiblen Balges, die automatische Herstellung vereinfacht und verbilligt wird.The present invention is also based on the object of improving a plastic closure with a screw ring that can be screwed onto the neck of a plastic container and with an insert part with a flexible bellows and spout, on the external thread of which a cap can be screwed, so that while maintaining good pouring properties, e.g. by means of a flexible bellows, the automatic production is simplified and cheaper.

Darüber hinaus soll mit dem neuen Kunststoffverschluß die Hand­habung desselben noch weiter erleichtert werden. Bei dem Kunst­stoffverschluß gemäß der Hauptanmeldung sind Schraubkappe und Schraubring durch eine Reißhaut miteinander verbunden. Eine solche Reißhaut weist häufig eine Perforation auf, so daß sie letztlich aus einer Reihe dünner Verbindungsstege besteht. Um den Kunststoffverschluß öffnen zu können, müssen durch Anheben von an der Schraubkappe angeordneten Bügeln, durch Anheben So der Schraubkappe selbst oder durch Drehen derselben die Reiß­haut bzw. entsprechende Kunststoffstege zerrissen werden. Ins­besondere beim Anheben einer solchen Kunststoffkappe setzt jedoch nicht nur die Reißhaut, sondern auch der eingestülpte Flansch einer Hubbewegung der Schraubkappe einen beträchtlichen Widerstand entgegen. Damit ist es schwierig, die Reißhaut durchzureißen. Wird die Kappe gegenüber dem Schraubring gedreht, so muß die Reißhaut auf ihrer gesamten Länge gleichzeitig durch­trennt werden bzw. sämtliche Verbindungsstege müssen gleich­zeitig zerrissen werden, so daß auch hierfür eine erhebliche Kraftanstrengung erforderlich ist. Die vorliegende Erfindung will hier eine zusätzliche Erleichterung schaffen, wobei gleich­zeitig die beschriebenen Vorteile des Verschlusses gemäß der Hauptanmeldung erhalten bleiben sollen. Diese Aufgabe wird da­durch gelöst, daß die Reißhaut als Abreißband ausgeführt ist, die Kappe also über das Abreißband mit dem Schraubring verbun­den ist.In addition, the handling of the same is to be made even easier with the new plastic closure. In the plastic closure according to the main application, the screw cap and the screw ring are connected to one another by a tear skin. Such tear skin often has a perforation, so that it ultimately consists of a series of thin connecting webs. In order to be able to open the plastic closure, the tear skin or corresponding plastic webs have to be torn by lifting the brackets arranged on the screw cap, by lifting the screw cap itself or by turning the same. In particular when lifting such a plastic cap, not only does the tear skin set, but also the indented one Flange a lifting movement of the screw cap against considerable resistance. This makes it difficult to tear through the tear skin. If the cap is turned with respect to the screw ring, the tear skin must be cut through over its entire length at the same time or all connecting webs must be torn apart at the same time, so that a considerable effort is also required for this. The present invention seeks to provide additional relief, while at the same time maintaining the described advantages of the closure according to the main application. This object is achieved in that the tear skin is designed as a tear-off tape, that is to say the cap is connected to the screw ring via the tear-off tape.

Ohne daß die Kappe angehoben, gedreht oder sonstwie bewegt wer­den muß, kann damit zunächst das Abreißband separat entfernt werden, wonach die Kunststoffkappe mit dem Ausgießer über den eingestülpten Balg relativ zum Schraubring beweglich ist.Without the cap having to be lifted, rotated or moved in any other way, the tear-off tape can thus first be removed separately, after which the plastic cap can be moved relative to the screw ring with the spout by means of the bellows that has been inserted.

In der bevorzugten Ausführungsform weist dabei die Kappe einen unteren Flansch auf, der an seinem äußeren Rand mit dem darunter angeordneten Schraubring einstückig verbunden ist.In the preferred embodiment, the cap has a lower flange, which is connected in one piece on its outer edge to the screw ring arranged underneath.

Für die Verbindung mit dem Abreißband kann dabei der Schraubring an seiner Kopfwand einen zusätzlichen zylindrischen Ansatz auf­weisen.For the connection to the tear-off tape, the screw ring can have an additional cylindrical extension on its head wall.

Bevorzugt ist außerdem eine Ausführungsform, bei welcher das Abreißband im wesentlichen über den gesamten Umfang des Kunst­stoffverschlusses verläuft. Zwischen Kappe und Schraubring wirkende Kräfte werden so auf einen großen Bereich verteilt.Also preferred is an embodiment in which the tear-off tape extends essentially over the entire circumference of the plastic closure. Forces acting between the cap and the screw ring are distributed over a large area.

Besonders zweckmäßig ist es dabei, wenn das Abreißband ein Hand­habeende aufweist. Dieses Handhabeende kann mit den Fingern er­griffen werden und das Abreißband wird dann sukzessive entlang des gesamten Umfanges von dem Kunststoffverschluß abgerissen.It is particularly expedient if the tear-off tape has a handle end. This end of the handle can be gripped with the fingers and the tear-off tape is then successively torn off along the entire circumference from the plastic closure.

Dabei kann das Abreißband beispielsweise über zwei parallel zwischen Kunststoffkappe und Schraubring umlaufende Schwach­stellen mit diesen verbunden sein. Die Schwachstellen können insbesondere als Reihen von dünnen Verbindungsstegen ausgebil­det sein. Beim Lösen des Abreißbandes werden dann zunächst im Bereich des Handhabeendes und anschließend sukzessive umlaufend einzelne dieser Stege abgerissen, wozu nur ein relativ geringer Kraftaufwand erforderlich ist.The tear-off tape can for example be parallel over two weak points encircling between the plastic cap and the screw ring must be connected to them. The weak points can be designed in particular as rows of thin connecting webs. When the tear-off tape is released, individual ones of these webs are then torn off first in the region of the handle end and then successively all the way around, for which purpose only a relatively small amount of force is required.

Bei einer zweckmäßigen Ausführungsform weist die Kappe an ihrem Kopfende einen Griffflansch auf. Dieser Griffflansch dient dazu, nach dem Abtrennen des Abreißbandes unter Herausstülpen des Balges die Kunststoffkappe mit dem Ausgießer herauszuziehen. Solange das Abreißband noch nicht von dem Verschluß entfernt ist, kann ein solcher Verschluß auch als Tragegriff dienen, je­denfalls solange das Gewicht des darunter befindlichen Behäl­ters nicht so groß ist, daß die Verbindung zwischen Abreißband und Schraubring oder Schraubkappe abreißt. Diese Gefahr ist jedoch gering, da sich bei intaktem Abreißband die Kraft auf den gesamten Umfang des Bandes bzw. auf die Gesamtheit der einzelnen Schwachstellen verteilt.In an expedient embodiment, the cap has a handle flange at its head end. This handle flange is used to pull out the plastic cap with the spout after the tear-off tape has been removed by pulling out the bellows. As long as the tear-off band is not yet removed from the closure, such a closure can also serve as a handle, at least as long as the weight of the container underneath is not so great that the connection between the tear-off band and the screw ring or screw cap breaks off. However, this risk is low since the force is distributed over the entire circumference of the belt or over the entirety of the individual weak points if the tear-off tape is intact.

Unabhängig von einem solchen Griffflansch kann die Schraubkappe gemäß einer besonderen Ausfihrungsform auch einen Bügel aufwei­sen, an welchem die Kappe mit dem Ausgießer unter Ausstülpen des Balges aus dem Behälterhals heraus bzw. von diesem weggezo­gen werden kann.Regardless of such a grip flange, the screw cap can also have a bracket according to a special embodiment, on which the cap with the spout can be pulled out or away from the container neck while the bellows is being pulled out.

Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der vor­liegenden Erfindung werden deutlich anhand der folgenden Be­schreibung einer bevorzugten Ausführungsform und der dazugehö­rigen Figuren. Es zeigen:

  • Figur 1 eine Seitenansicht eines Kunststoffverschlusses, teil­weise im Schnitt, und
  • Figur 2 eine Draufsicht auf den Kunststoffverschluß gemäß Figur 1 von oben.
Further advantages, features and possible uses of the present invention will become clear from the following description of a preferred embodiment and the associated figures. Show it:
  • Figure 1 is a side view of a plastic closure, partially in section, and
  • Figure 2 is a plan view of the plastic closure of Figure 1 from above.

Ein Schraubring 2 ist auf den Behälterhals 11 eines Behälters aufgeschraubt. Am unteren Rand des Schraubringes 2 kann noch ein Garantiering 5 angeformt sein, welcher mit geeigneten Vor­sprüngen am Behälterhals 11 verhakt ist und sicherstellen soll, daß der Schraubring 2 ohne Zerstören der Verbindung zwischen diesem und dem Garantiering 5 nicht vom Behälterhals 11 abge­schraubt bzw. abgenommen werden kann.A screw ring 2 is on the container neck 11 of a container screwed on. At the lower edge of the screw ring 2, a guarantee ring 5 can be formed, which is hooked onto the container neck 11 with suitable projections and is intended to ensure that the screw ring 2 cannot be unscrewed or removed from the container neck 11 without destroying the connection between the latter and the guarantee ring 5 can.

An der oberen, im Querschnitt horizontal verlaufenden Kopfwand des Schraubringes 2 befindet sich ein zylindrischer Ansatz, der über eine umlaufende Schwachstelle einstückig mit einem Abreißband 3 verbunden ist. Ein Ende des umlaufenden Abreiß­bandes 3 ist mit einer Handhabe 4 versehen. Parallel zu der Schwachstelle, welche Schraubring 2 und Abreißband 3 verbin­det, läuft eine weitere Schwachstelle um den Verschluß herum, welche die Verbindung zwischen dem Abreißband 3 und dem unte­ren Rand eines Flansches 9 der Schraubkappe 1 darstellt. Die Kopfwand der Schraubkappe 1 weist einen umlaufenden Flansch 8 auf, welcher als Griffflansch ausgebildet sein kann und welcher gegebenenfalls an seinem äußeren Umfang eine Riffelung zum besseren Auf- und Abschrauben der Kunststoffkappe 1 aufweist. Zusätzlich ist die Schraubkappe 1 mit hochklappbaren Bügeln 6 versehen, welche an den Flansch 8 einstückig angeformt sind. Die hochklappbaren Kunststoffbügel 6 erleichtern das Heraus­ziehen des Ausgießers 7 unter Ausstülpen des Balges 10, wenn die Kunststoffkappe 1 auf den Ausgießer 7 aufgeschraubt ist.On the upper, cross-sectionally extending head wall of the screw ring 2 there is a cylindrical extension which is connected in one piece to a tear-off strip 3 via a circumferential weak point. One end of the circumferential tear tape 3 is provided with a handle 4. Parallel to the weak point, which connects the screw ring 2 and the tear-off band 3, another weak point runs around the closure, which represents the connection between the tear-off band 3 and the lower edge of a flange 9 of the screw cap 1. The top wall of the screw cap 1 has a circumferential flange 8, which can be designed as a handle flange and which may have corrugations on its outer circumference for better screwing and unscrewing the plastic cap 1. In addition, the screw cap 1 is provided with flaps 6 which are integrally formed on the flange 8. The foldable plastic brackets 6 make it easier to pull out the spout 7 by pulling out the bellows 10 when the plastic cap 1 is screwed onto the spout 7.

In der Draufsicht der Figur 2 ist in der Mitte die Schraubkappe 1 bzw. deren Kopfwand zu erkennen, die den umlaufenden Flansch 8 aufweist, an welchem wiederum Bügel 6 einstückig angeformt sind. Der Außendurchmesser der Bügel 6 entspricht bei der dar­gestellten Ausführungsform ziemlich genau dem Außendurchmesser des darunterliegenden unteren Flansches 9 der Schraubkappe, unter welchem wiederum das Abreißband 3 konzentrisch verläuft, welches in Figur 2 durch eine doppelgestrichelte Linie ange­deutet ist. Ein Ende des Abreißbandes 3 ist mit einer Handha­be 4 versehen, welche zum Lösen des Abreißbandes 3 radial von dem Verschluß wegbewegt wird, wobei das Abreißband entlang der parallel umlaufenden Schwachstellen von dem Schraubring 2 und der Schraubkappe 1 abgetrennt wird. Nach dem Entfernen des Ab­reißbandes 3 sind Schraubkappe 1 und Schraubring 2 voneinander getrennt und der Ausgießer 7 kann unter Ausstülpen des Balges 10 ausgezogen werden.In the plan view of FIG. 2, the screw cap 1 or its head wall can be seen in the middle, which has the circumferential flange 8, on which in turn brackets 6 are integrally formed. In the embodiment shown, the outside diameter of the stirrups 6 corresponds almost exactly to the outside diameter of the lower flange 9 of the screw cap underneath, under which in turn the tear-off tape 3 runs concentrically, which is indicated in FIG. 2 by a double-dashed line. One end of the tear-off tape 3 is provided with a handle 4, which is moved radially away from the closure to release the tear-off tape 3, the tear-off tape being removed from the screw ring 2 and the screw cap 1 is separated. After the tear-off tape 3 has been removed, the screw cap 1 and the screw ring 2 are separated from one another and the spout 7 can be pulled out while the bellows 10 is being pulled out.

Die Kunststoffbügel 6 sind, wie man in Figur 2 erkennt, an zwei gegenüberliegenden Seiten über breite und haltbare Stege mit dem Flansch 8 der Schraubkappe 1 verbunden, während um 90° ver­setzt hierzu beim Hochklappen des Bügels 6 abreißbare, schwache Verbindungen zwischen Bügel 6 und Flansch 8 bestehen. Der Aus­gießer 7 mit dem Balg 10 und einem daran anschließenden Dich­tungsrand werden getrennt von den übrigen Teilen des Kunststoff­verschlusses hergestellt, die ihrerseits alle einstückig mit­einander verbunden sind, und so in einem einzigen Herstellungs­schritt gemeinsam gegossen werden. Diese einstückig miteinan­der verbundenen Teile sind die Schraubkappe 1 mit den Bügeln 6, das Abreißband 3, der Schraubring 2 und der Garantiering 5.As can be seen in FIG. 2, the plastic brackets 6 are connected on two opposite sides to the flange 8 of the screw cap 1 by means of wide and durable webs, while offset by 90 ° when the bracket 6 is folded up, weak connections between the bracket 6 and the flange that can be torn off 8 exist. The spout 7 with the bellows 10 and an adjoining sealing edge are produced separately from the other parts of the plastic closure, which in turn are all connected to one another in one piece, and are thus cast together in a single production step. These parts which are connected in one piece are the screw cap 1 with the brackets 6, the tear-off tape 3, the screw ring 2 and the guarantee ring 5.

Für die Montage wird die Schraubkappe 1 auf den Ausgießer 7 aufgeschraubt und anschließend wird der gesamte Verschluß, in welchem Ausgießer 7, Balg 10 und der daran angesetzte Dichtungs­rand aufgenommen sind, mit dem Schraubring 2 auf den Behälter­hals 11 aufgeschraubt. Dabei rasten Hakenverbindungen zwischen Garantiering 5 und Behälterhals 11 ineinander ein.For assembly, the screw cap 1 is screwed onto the spout 7 and then the entire closure, in which the spout 7, bellows 10 and the sealing edge attached to it, are screwed onto the container neck 11 with the screw ring 2. Hook connections between the guarantee ring 5 and the container neck 11 snap into one another.

Abgesehen von der Art der Verbindung zwischen Schraubkappe und Schraubring kann der Verschluß gemäß der vorliegenden Er­findung sämtliche Merkmale der in der Hauptanmeldung P 37 30 225.6 beschriebenen Verschlüsse aufweisen, die insoweit ausdrücklich in Bezug genommen wird.Apart from the type of connection between the screw cap and the screw ring, the closure according to the present invention can have all the features of the closures described in the main application P 37 30 225.6, which is expressly referred to in this respect.
