Abstract

A sheet-material piercer (1) for a container closure (2) of the push-pull type is of essentially rotationally symmetrical design and can be inserted into the container closure (2) in the direction of the axis of rotation of symmetry (R) such that it can be displaced axially independently of the push-pull part of the container closure (2). The sheet-material piercer (1) is in one piece and has at least one sealing formation (16, 17, 18) which is likewise of rotationally symmetrical design and is arranged between an actuating end (13) and a piercing end (14). The sealing formation (16, 17, 18) is designed for sealing and latching contact with the container closure (2). Also proposed is a container closure (2) for a container (3) with a so-called push-pull closure and such a sheet-material piercer (1).

Description

Die Erfindung betrifft einen Behälterverschluss mit einem Folienstecher , insbesondere Behälterverschlüsse vom ,push-pull'-Typ, die mit einem Zusatzraum für die Einlagerung einer Substanz von flüssiger oder pulverförmiger Konsistenz ausgestattet sind .The invention relates to a container closure with a foil tube, in particular container closures of the "push-pull" type, which are equipped with an additional space for the storage of a substance of liquid or powdery consistency.

Auf dem Gebiet der Sportgetränke, zunehmend aber auch in immer weiteren Marktsektoren, besteht ein stark steigender Bedarf, vitaminisierte oder sonstwie angereicherte Getränke in geeigneten Behältern anbieten zu können. Es besteht auch ein klarer Trend, diese Additive erst unmittelbar vor dem Gebrauch beizumischen. Oft werden Getränkeflaschen bevorzugt, bei denen eine Einhandbedienung möglich ist. Dazu eignen sich Getränkeflaschen mit sogenannten "push-pull"-Verschlüssen. Derartige Getränkeverschlüsse können nicht nur einfach geöffnet, sondern nach Gebrauch auch mit einfachem Daumendruck wieder verschlossen werden.In the field of sports drinks, but increasingly in ever more market sectors, there is a strong increasing demand to be able to offer vitaminized or otherwise enriched drinks in suitable containers. There is also a clear trend to add these additives just before use. Often, beverage bottles are preferred in which a one-hand operation is possible. For this purpose, beverage bottles with so-called "push-pull" shutters are suitable. Such beverage closures can not only be opened easily, but closed after use with a simple thumb pressure again.

Die WO 2006/099768 zeigt einen Behälterverschluss für einen Behälter mit einem sogenannten "push-pull"-Verschluss. Dieser Behälterverschluss hat ein um eine Behälteröffnung anbringbares Hüllenteil mit einer Dichtlippe und ein am Hüllenteil verschieblich angebrachtes Schiebeteil (für die push-pull-Betätigung), wobei durch Verschieben des Schiebeteils auf dem Hüllenteil eine Ausflussöffnung freigebbar oder verschliessbar ist. An der Dichtlippe ist eine aufreissbare oder durchstechbare Verschlussfolie angebracht, wodurch ein gegenüber dem Behälterinhalt dicht abgeteilter Zusatzraum im dem Schiebeteil zugewandten Innenraum des Hüllenteils gebildet wird. Im Hüllenteil ebenfalls verschieblich angebracht ist ein Folienstecher (bestehend aus einem Dorn und einer Aufreiss- und Durchstosseinrichtung), wobei durch Betätigung des Folienstechers die Verschlussfolie aufreissbar oder durchstechbar ist und wobei dadurch ein in den Zusatzraum einbringbares Additiv in den Behälter gelangen kann. Ein Nachteil dieses Folienstechers ist, dass der zweiteilig aufgebaut ist, was Herstellung und Montage eines damit ausgerüsteten Behälterverschlusses teurer und aufwendiger macht. Ein weiterer Behälterverschluss mit einteiligem Folienslecher ist aus US 2004/ 0155061 bekannt; ein rasten der Kontakt des Folienstechers ist jedoch nicht offenbart.The WO 2006/099768 shows a container closure for a container with a so-called "push-pull" closure. This container closure has a shell part attachable to a container opening with a sealing lip and a sliding part displaceably mounted on the shell part (for the push-pull actuation), wherein an outflow opening can be opened or closed by displacing the sliding part on the shell part. At the sealing lip a rupturable or pierceable closure film is attached, whereby a relative to the container contents densely partitioned additional space formed in the sliding part facing the interior of the shell part becomes. Also mounted slidably in the shell part is a film scraper (consisting of a mandrel and a tear-open and puncture device), wherein the closure foil can be opened or pierced by actuation of the foil scissors and whereby an additive which can be introduced into the additional space can thus enter the container. A disadvantage of this film scissors is that the two-piece is constructed, which makes the manufacture and assembly of a container closure equipped with it more expensive and expensive. Another container closure with one-piece foil plate is made US 2004/0155061 known; a rest of the contact of the slide tube is not disclosed.

Es ist deshalb die Aufgabe, einen verbesserten Behälterverschluss vom push-pull'-Typ mit einem Folienstecher anzugeben.It is therefore an object to provide an improved container closure of the push-pull type with a foil cup.

Diese Aufgabe wird durch die Merkmale von Patentansprüch 1 gelöst.This object is solved by the features of patent claim 1.

Die Lösung besteht darin, dass der Folienstecher einstückig ist und mindestens eine Dichtausformung aufweist, die zwischen einem Betätigungsende und einem Stechende angeordnet ist und zu dichtendem und einrastfähigem Kontakt mit dem Behälterverschluss ausgebildet ist ; d.h. bei einem erfindungsgemässen Behälterverschluss für einen Behälter mit einem sogenannten ,push-pull'-verschluss ist der Folienstecher dichtend und einrastend im Hüllenteil positionierbar. Es handelt sich somit um eine Verbesserung des beschriebenen Stands der Technik.The solution is that the film cup is integral and has at least one Dichtausformung, which is arranged between an actuating end and a piercing end and is designed for sealing and latchable contact with the container closure; i.e. in the case of a container closure according to the invention for a container with a so-called push-pull closure, the foil cup can be positioned in the envelope part in a sealing and latching manner. It is therefore an improvement of the described prior art.

Der Hauptvorteil des Folienstechers besteht in seiner Einstückigkeit und darin, dass er einrastfähig ausgebildet ist. Neben der einfacheren Herstellbarkeit erreicht man mit der vorgeschlagenen Lösung auch, dass der Folienstecher bei der Montage des Behälterverschlusses lediglich von unten her in das Hüllenteil hineingedrückt werden muss und dort einrastet. Somit wird die Montage vereinfacht.The main advantage of the slide tube is its integral nature and the fact that it is capable of being locked in place. In addition to the ease of manufacture can be achieved with the proposed solution also that the film cup during assembly of the container closure only has to be pressed from below into the shell part and there snaps. Thus, the assembly is simplified.

Die zwischen dem Betätigungsende und dem Stechende angeordnete mindestens eine Dichtausformung, die zu dichtendem und einrastfähigem Kontakt mit dem Behälterverschluss ausgebildet ist, ermöglicht die erwähnte einrastende Positionierung des Folienstechers im Behälterverschluss.The at least one sealing formation arranged between the actuating end and the piercing end, which is designed for sealing and latchable contact with the container closure, makes possible the aforementioned latching positioning of the film turret in the container closure.

Als Dichtausformung sind dabei konstruktive Merkmale gemeint, mit denen primär eine dichtende Wirkung erzielt wird. Im vorliegenden Fall kann dies durch eine Formgebung erzielt werden, die ein sattes und gegenseitiges Anliegen an der Dichtstelle bewirkt, also beispielsweise unter Ausnützung der natürlichen Elastizität und Steifigkeit der verwendeten Materialien. Der allgemeine Begriff ,Dichtausformung' wurde gewählt, weil diese Merkmale, wie dem Fachmann bekannt, in kinematischer Umkehr grundsätzlich oft auf zwei komplementäre Arten realisierbar sind. So können entsprechend gestaltete kreisförmige Dichtstege entweder am Folienstecher oder am Hüllenteil vorhanden sein. Da die Dichtwirkung jedoch stets ein Zusammenwirken von Teilen (z.B. Dichtsteg und Dichtsitz) erfordert, wird bevorzugt von einer Dichtausformung an der betreffenden Stelle gesprochen.As Dichtausformung constructive features are meant, which primarily a sealing effect is achieved. In the present case, this can be achieved by a shaping, which causes a rich and mutual concern at the sealing point, so for example by taking advantage of the natural elasticity and rigidity of the materials used. The general term 'seal formation' was chosen because these features, as known to those skilled in the art, can generally be realized in kinematic reversal, often in two complementary ways. Thus, correspondingly shaped circular sealing webs can be present either on the foil tube or on the shell part. However, since the sealing effect always requires cooperation of parts (e.g., sealing ridge and sealing seat), it is preferred to speak of a sealing formation at the site concerned.

Die mindestens eine Dichtausformung kann zwecks Materialersparnis tellerartig ausgeführt sein und zwecks besserer Führung des Folienstechers im Hüllenteil können zwei derartige kreisförmige Dichtausformungen mit gleichen Kreisdurchmessern versehen sein. Besonders vorteilhaft sind drei kreisförmige, tellerartige Dichtausformungen, weil so in der Ausgangsstellung (Folienstecher noch nicht betätigt) eine gute Abdichtung des Zusatzraumes nach aussen möglich ist. Insbesondere flüssige Additive sind dann besonders gut geschützt.The at least one sealing formation can be made plate-like for the purpose of saving material, and for the purpose of better guiding the film retractor in the shell part, two such circular sealing formations can be provided with the same circular diameters. Particularly advantageous are three circular, plate-like Dichtausformungen, because so in the starting position (not yet actuated Folienstcher) a good seal of the additional space to the outside is possible. In particular, liquid additives are then particularly well protected.

Besonderes vorteilhaft ist auch eine im wesentlichen leicht abgeschrägte Platte am Stechende des Folienstechers. Die Platte kann dann eine einfache geometrische Form aufweisen, beispielsweise viereckig. Durch die schräg vorstehende Kante wird die Verschlussfolie zuverlässig durchstochen und die Plattenfläche garantiert, dass das Durchstichloch in der Folie so gross wird, dass das Additiv vollständig und schnell in den Behälter gelangt.Particularly advantageous is also a substantially slightly bevelled plate at the piercing end of the film cutter. The plate can then have a simple geometric shape, for example quadrangular. The obliquely protruding edge reliably punctures the sealing foil and the plate surface guarantees that the puncture hole in the foil becomes so large that the additive passes completely and quickly into the container.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles näher erläutert. In den Zeichnungen zeigen:

The invention will be explained in more detail below with reference to an embodiment. In the drawings show:

in cross-section a foil tube in a 'push-pull' container closure in the drinking state, and
Fig. 4
a 3D view of a container closure with attached protective cap.

Die Fig. 1 zeigt im Querschnitt einen Folienstecher 1 in einem ,push-pull'-Behälterverschluss 2 im Kaufzustand bzw. in einer Ausgangsstellung. In dieser Stellung ist der ,push-pull'-Verschluss geschlossen und der Folienstecher 1 noch nicht aktiviert. Der Behälterverschluss 2 ist dabei auf einen Behälter 3 aufgesetzt und der ,push-pull'-Verschluss ist von einer aufgesetzten Schutzkappe 4 abgedeckt.The Fig. 1 shows in cross-section a film scraper 1 in a push-pull container closure 2 in the purchase state or in a starting position. In this position, the push-pull closure is closed and the foil cup 1 is not yet activated. The container closure 2 is placed on a container 3 and the 'push-pull' closure is covered by an attached protective cap 4.

Der Behälterverschluss 2 hat ein Hüllenteil 5 mit einem darauf aufgesetzten und auf dem Hüllenteil 5 verschiebbaren Schiebeteil 6. Das Schiebeteil 6 bildet dabei den eigentlichen ,push-pull'-Verschluss; d.h. es muss zum Schliessen oder Öffnen des Behälterverschlusses 2 in die eine oder andere Stellung gedrückt (push) oder gezogen (pull) werden. Wegen des vorstehenden Wulstes 7 ist ein solcher Verschluss auch für die Einhandbedienung geeignet. Der Behälterverschluss 2 hat ferner in einer zentralen rohrähnlichen Führung 8 den bereits erwähnten Folienstecher 1. Einerseits aus Gründen der Materialersparnis, andererseits um den Flüssigkeitsaustrittsquerschnitt nicht unnötig zu verkleinern ist die Führung 8 vorteilhafterweise mit radial angeordneten Materialbrücken 9 mit den übrigen Teilen des Hüllenteils 5 verbunden. Im vorliegenden Ausführungsbeispiel sind drei derartige Materialbrücken 9 vorgesehen.The container closure 2 has a shell part 5 with a sliding part 6 placed thereon and displaceable on the shell part 5. The sliding part 6 forms the actual push-pull closure; ie it has to close or open the container closure 2 in one or the other Position pressed (push) or pulled (pull). Because of the protruding bead 7, such a closure is also suitable for one-handed operation. On the one hand, for reasons of saving material, on the other hand not to unnecessarily reduce the liquid outlet cross-section, the guide 8 is advantageously connected to the remaining parts of the shell part 5 with radially arranged material bridges 9. In the present embodiment, three such material bridges 9 are provided.

Das Hüllenteil 5 hat ferner eine heruntergezogene Lippe 10 an der eine Verschlussfolie 11 angebracht ist. In intaktem Zustand (und solange der Behälterverschluss 2 auf den Behälter 3 aufgesetzt ist) verhindert die Verschlussfolie 11 ein Ausfliessen des Behälterinhaltes. Mit der Verschlussfolie 11 wird auch ein gegenüber dem Behälterinhalt dicht abgeteilter Zusatzraum 12 in dem dem Schiebeteil 6 zugewandten Innenraum des Hüllenteils 5 geschaffen. Es versteht sich von selbst, dass der Zusatzraum 12 um so grösser ist, je weiter die Lippe 10 nach unten gezogen ist.The shell part 5 further has a pulled-down lip 10 on which a closure film 11 is attached. In intact condition (and as long as the container closure 2 is placed on the container 3) prevents the sealing film 11 outflow of the container contents. With the closure film 11, a relative to the container contents densely partitioned additional space 12 in the sliding part 6 facing the interior of the shell part 5 is created. It goes without saying that the additional space 12 is the greater, the farther the lip 10 is pulled down.

Der Folienstecher 1 ist im wesentlichen rotationssymmetrisch ausgebildet und wie erwähnt achsial verschieblich und zentral (also in Richtung seiner Rotationssymmetrieachse R) im Behälterverschluss 2 angeordnet. Die achsiale Verschiebbarkeit des Folienstechers 1 ist unabhängig von der Stellung des push-pull-Teils (also des Schiebeteils 6) des Behälterverschlusses 2.The film cup 1 is formed substantially rotationally symmetrical and as mentioned axially displaceable and centrally (ie in the direction of its rotational symmetry axis R) arranged in the container closure 2. The axial displaceability of the film scissors 1 is independent of the position of the push-pull part (ie the sliding part 6) of the container closure. 2

Der Folienstecher 1 hat ein Betätigungsende 13 und ein Stechende 14. Das Betätigungsende 13 ist tellerartig ausgeführt, um die bequeme Bedienung, beispielsweise mit dem Daumen einer Hand, zu erleichtern. Das Stechende 14 hat eine leicht schräg angeordnete Platte 15. Die Platte 15 kann dann eine einfache geometrische Form aufweisen, beispielsweise viereckig. Mit der unteren schräg vorstehende Kante dieser Platte 15 kann die Verschlussfolie 11 beim Herunterdrücken des Folienstechers 1 zuverlässig durchstochen werden. Der Folienstecher 1 als Ganzes hat in seiner achsialen Längserstreckung ein im wesentliches kreuzartiges Verstärkungsprofil, was bei guter Festigkeit wiederum eine Materialersparnis ermöglicht.The foil cup 1 has an actuating end 13 and a piercing end 14. The actuating end 13 is plate-like, in order to facilitate the convenient operation, for example with the thumb of one hand. The piercing 14 has a slightly obliquely arranged plate 15. The plate 15 can then be a simple have geometric shape, for example quadrangular. With the lower obliquely projecting edge of this plate 15, the closure film 11 can be reliably penetrated when pressing down the film die 1. The film tube 1 as a whole has in its axial longitudinal extent a substantially cross-type reinforcing profile, which in turn allows good material savings with good strength.

Der Folienstecher 1 hat ferner erste und zweite tellerartige kreisförmige Dichtausformungen 16, 17 von gleichem Kreisdurchmesser, die zwischen dem Betätigungsende 13 und dem Stechende 14 angeordnet sind. Die erste und die zweite Dichtausformung 16, 17 gleiten in der Führung 8. Dichtstellen A und B befinden sich an den Kontaktstellen der Dichtausformungen 16 und 17 mit der Führung 8.The film cup 1 further has first and second plate-like circular Dichtausformungen 16, 17 of the same circular diameter, which are arranged between the actuating end 13 and the piercing end 14. The first and second Dichtausformung 16, 17 slide in the guide 8. sealing points A and B are located at the contact points of the Dichtausformungen 16 and 17 with the guide. 8

Der Folienstecher 1 hat weiterhin eine dritte tellerartige kreisförmige Dichtausformung 18, die ebenfalls zwischen dem Betätigungsende 13 und dem Stechende 14 angeordnet ist, aber unterhalb der Dichtausformungen 16 und 17. Die dritte Dichtausformung 18 dient zum Verschliessen der gesamten Austrittsöffnung. Eine weitere Dichtstelle C befindet sich deshalb an der Kontaktstelle der Dichtausformung 18 mit dem Ausflussrohr des Hüllenteils 5. Ein Abschlussteller 19 hat keine dichtende Funktion und dient lediglich der visuellen Verschönerung (klarer Abschluss im ungebrauchten Zustand).The film cup 1 further has a third plate-like circular Dichtausformung 18, which is also disposed between the actuating end 13 and the piercing end 14, but below the Dichtausformungen 16 and 17. The third Dichtausformung 18 serves to close the entire outlet opening. A further sealing point C is therefore located at the contact point of the Dichtausformung 18 with the spout of the shell part 5. A closure plate 19 has no sealing function and is only for visual beautification (clear conclusion in the unused state).

Die Dichtausformungen 16,17,18, oder mindestens eine davon, sind zudem so ausgebildet, dass in der in der Figur 1 dargestellten Stellung ein einrastfähiger Kontakt zwischen dem Folienstecher 1 und der Führung 8 im Hüllenteil 5 entsteht. Dies kann z.B. mit geeignet dimensionierten Einrastrillen oder Nuten erfolgen. Aufgrund der offenbarten Konstruktionsweise ist es somit möglich, den Folienstecher 1 von unten her in das Hüllenteil 5 einzuführen und mit etwas Druck in der gezeigten Position einrasten zu lassen.The Dichtausformungen 16,17,18, or at least one of them, are also designed so that in the in the FIG. 1 shown position a latchable contact between the film pocket 1 and the guide 8 in the shell part 5 is formed. This can be done, for example, with suitably dimensioned locking grooves or grooves. Due to the disclosed construction, it is thus possible to insert the foil cup 1 from below into the shell part 5 and to let it snap into place with some pressure.

Ein im Zusatzraum eingelagertes Additiv, insbesondere eine Flüssigkeit, ist somit gegen Auslaufen geschützt. Die Dichtstellen A,B,C verhindern ein Auslaufen nach aussen, insbesondere auch durch die Öffnung in der Führung 8. Die (intakte) Verschlussfolie 11 verhindert ein Auslaufen nach innen. Selbst wenn in dieser Stellung der push-pull-Verschluss geöffnet würde, bliebe somit der Inhalt des Behälters 3 wie auch der Inhalt des Zusatzraumes 12 vor Auslaufen geschützt.An additive stored in the additional space, in particular a liquid, is thus protected against leakage. The sealing points A, B, C prevent leakage to the outside, in particular through the opening in the guide 8. The (intact) sealing film 11 prevents leakage to the inside. Even if the push-pull closure would be opened in this position, thus the contents of the container 3 as well as the contents of the additional space 12 would remain protected against leakage.

Die Fig. 2 zeigt im Querschnitt einen Folienstecher 1 in einem ,push-pull'-Behälterverschluss 2 gemäss Fig. 1 im Stechzustand bzw. in einer Betätigungstellung. In dieser Stellung ist der ,push-pull'-Verschluss noch immer geschlossen, der Folienstecher 1 ist aber aktiviert, d.h. er wurde heruntergedrückt und die Additivzugabe ist somit erfolgt.The Fig. 2 shows in cross-section a film scraper 1 in a 'push-pull' container closure 2 according to Fig. 1 in the lancing state or in an actuating position. In this position, the push-pull closure is still closed, but the foil cup 1 is activated, ie it has been pressed down and the addition of additive has thus taken place.

Zur Erreichung dieser Position wurde der Folienstecher 1 mittels Druck auf das Betätigungsende 13 soweit heruntergedrückt, dass es nicht mehr vorsteht. Auch in dieser Position ist eine Einrastfunktion vorgesehen, was beispielsweise an der ersten Dichtausformung 16 oder an der zweiten Dichtausformung 17 vorgesehen sein kann. Die aufgerissene Verschlussfolie 11 ist hier nicht dargestellt.To achieve this position, the film cup 1 was pressed down by pressing the operating end 13 so far that it no longer protrudes. Also in this position, a latching function is provided, which may be provided, for example, on the first sealing formation 16 or on the second sealing formation 17. The torn-open closure film 11 is not shown here.

Eine Dichtstelle D befindet sich jetzt an der Kontaktstelle der ersten Dichtausformung 16 mit der Führung 8. Sie verhindert ein Ausfliessen des additiv-versetzten Inhaltes aus dem Behälter durch die Öffnung mit der Führung 8. Weitere Dichtstellen E und F befinden sich an Kontaktstellen des Schiebeteils 6 mit dem Hüllenteil 5. Diese verhindert ein Ausfliessen des additiv-versetzten Inhaltes aus dem Behälter aus dem noch geschlossenen push-pull-Verschluss.A sealing point D is now located at the contact point of the first Dichtausformung 16 with the guide 8. It prevents leakage of additive-added content from the container through the opening with the guide 8. More sealing points E and F are located at contact points of the sliding part. 6 with the shell part 5. This prevents leakage of the additive-added content from the container from the still closed push-pull closure.

In der in der Figur 2 gezeigten Stellung wäre es grundsätzlich auch möglich, den Folienstecher 1 unter Überwindung der Einrastkraft wieder herauszuziehen und ganz vom Hüllenteil 5 zu lösen.In the in the FIG. 2 shown position, it would also be possible in principle to pull out the foil cup 1, overcoming the latching force again and completely from the shell part 5 to solve.

Die Fig. 3 zeigt im Querschnitt einen Folienstecher 1 in einem ,push-pull'-Behälterverschluss 2 gemäss Fig. 1 im Trinkzustand. In dieser Stellung ist der ,push-pull'-Verschluss geöffnet und der Folienstecher 1 noch immer aktiviert. Der Behälterverschluss 2 ist trinkbereit. Der Ausflussweg G ist mit einem Richtungspfeil angedeutet.The Fig. 3 shows in cross-section a film scraper 1 in a 'push-pull' container closure 2 according to Fig. 1 in the drinking state. In this position, the 'push-pull' shutter is opened and the sheet-metal cup 1 is still activated. The container closure 2 is ready to drink. The outflow path G is indicated by a directional arrow.

Zur Erreichung dieser Position wurde das Schiebeteil 6 nach oben gezogen. Damit kann der Inhalt des Behälters 3 über einen Ausflussweg G durch eine Trinköffnung 20 nach aussen fliessen.To achieve this position, the sliding part 6 was pulled upwards. Thus, the contents of the container 3 via an outflow G flow through a drinking opening 20 to the outside.

Die Fig. 4 zeigt schliesslich noch eine 3D-Ansicht eines erfindungsgemässen Behälterverschluss 2 gemäss Fig. 1 mit aufgesetzter Schutzkappe 4.The Fig. 4 finally shows a 3D view of a container closure 2 according to the invention Fig. 1 with attached protective cap 4.

Die Funktionsweise und Bedienung eines gattungsgemässen Behälterverschlusses ist allgemein bekannt und im übrigen auch im eingangs beschriebenen Stand der Technik detailliert beschrieben.The operation and operation of a generic container closure is well known and otherwise described in detail in the prior art described above.
