In order to make the closure easier to handle and the warranty strip more secure, the release tab (58) consists of a sector of the cap which is separated from the rest of the cap (38) by a gap (60). A tear strip (62) holds the release tab (58) on to the rest of the cap (38).

Description

Die Erfindung betrifft einen Flaschenverschluss aus Kunststoff der im Oberbegriff des Anspruches 1 definierten Gattung.The invention relates to a bottle cap made of plastic of the type defined in the preamble of claim 1.

Flaschenverschlüsse dieser Art sind in grosser Zahl bekannt, so beispielsweise aus der EP-A-0 009 525. Diese Flaschenverschlüsse weisen an der Verschlußkappe radial vorstehende Griffteile auf. Weiter sind die Flaschenverschlüsse mit einem Garantieband und einer Aufreißlasche versehen, wobei insbesondere auch die Aufreißlasche radial vorstehend ist. Da die Aufreißlasche zum Abreißen bestimmt ist und insofern über Abreißstege mit dem Verschlußkappenteil verbunden ist, besteht die Gefahr, dass die Aufreißlasche ungewollt abgerissen wird, so beispielsweise beim Sortieren oder Aufsetzen der Flaschenverschlüsse oder beim Handhaben der mit den Flaschenverschlüssen versehenen Flaschen. Hinzu kommt, dass die vorstehenden Teile die maschinelle Verarbeitung der Flaschenverschlüsse erschweren. Der geschlossene, umlaufende Rand der Verschlußkappe erschwert schliesslich das wiederholte Öffnen und Schliessen der Verschlußkappe.Bottle closures of this type are known in large numbers, for example from EP-A-0 009 525. These bottle closures have radially protruding grip parts on the closure cap. Furthermore, the bottle closures are provided with a guarantee band and a tear-open tab, the tear-open tab in particular also projecting radially. Since the tear-open tab is intended to be torn off and is therefore connected to the closure cap part by means of tear-off webs, there is a risk that the tear-open tab will be torn off unintentionally, for example when sorting or putting on the bottle caps or when handling the bottles provided with the bottle caps. In addition, the protruding parts complicate the mechanical processing of the bottle caps. The closed, all-round edge of the closure cap ultimately makes it difficult to repeatedly open and close the closure cap.

Aufgabe der Erfindung ist es, einen Flaschenverschluss der eingangs genannten Gattung zu schaffen, bei dem insbesondere die Aufreißlasche des Garantiebandes so angeordnet ist, dass die genannten Nachteile vermieden werden.The object of the invention is to provide a bottle stopper of the type mentioned in the introduction, in which in particular the tear-open tab of the guarantee tape is arranged in such a way that the disadvantages mentioned are avoided.

Die gestellte Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.

Dadurch, dass die Aufreißlasche in die Verschlußkappe integriert ist und einen Sektor derselben bildet, gliedert sie sich in die Kontur der Verschlußkappe ein und bildet keinen vorstehenden Teil. Weiter ist die Aufreißlasche einfacher zu handhaben, da sie von der Oberseite der Verschlußkappe lediglich innerhalb des nach oben vorstehenden Randteiles durch radiales Auspressen und Ausziehen abgerissen werden kann. Ferner wird die Garantiefunktion verbessert, denn ein beschädigter Garantieverschluss, d.h. eine abgerissene Aufreißlasche hinterlässt an der Verschlußkappe eine kleine Lücke, die optisch stärker ins Auge fällt, als wenn eine seitlich vorstehende Abreißlasche des bekannten Flaschenverschlusses beschädigt ist. Dadurch, dass der Griffteil als nach unten weisende Ausnehmung im Rand der Verschlußkappe ausgebildet ist, die im Originalzustand vom Garantieband abgedeckt ist, wird eine grosse Grifföffnung für den Griffteil möglich und der Griffteil ist nach dem Entfernen des Garantiebandes besser zu erfassen. Dies erleichtert das Manipulieren der Verschlußkappe. Ein weiterer wesentlicher Vorteil liegt darin, dass der Griffteil erst zugänglich ist, wenn das Garantieband entfernt ist, so dass die Garantiefunktion des Flaschenverschlusses verbessert ist. Es ergeben sich somit wesentliche Vorteile bei der maschinellen Verarbeitung der Flaschenverschlüsse von der Herstellung desselben bis zum Ansetzen an die Flasche sowie auch später bei der Handhabung der mit dem Flaschenverschluss versehenen Flasche. Durch die Integration der Abreißlasche und des Griffteiles in die Verschlußkappe wird schliesslich auch das Aussehen des Flaschenverschlusses wesentlich verbessert.Because the pull tab is integrated into the closure cap and forms a sector thereof, it is integrated into the contour of the closure cap and does not form a projecting part. Furthermore, the tear-open tab is easier to handle, since it can only be torn off from the top of the closure cap within the upwardly projecting edge part by radial pressing and pulling out. Furthermore, the warranty function is improved because a damaged warranty lock, i.e. a torn tear-off tab leaves a small gap on the cap, which is more visually striking than if a protruding tear-off tab of the known bottle cap is damaged. The fact that the handle part is designed as a downward-facing recess in the edge of the closure cap, which is covered by the guarantee tape in the original state, makes a large handle opening possible for the handle part and the handle part is easier to grasp after the guarantee tape has been removed. This facilitates manipulation of the cap. Another important advantage is that the handle part is only accessible when the guarantee tape has been removed, so that the guarantee function of the bottle stopper is improved. This results in significant advantages in the mechanical processing of the bottle caps from the production of the same to the attachment to the bottle and also later in the handling of the bottle provided with the bottle cap. By integrating the tear-off tab and the handle part into the cap, the appearance of the bottle cap is also significantly improved.

Dies alles wird erreicht bei einem Flaschenverschluss, der über einen Befestigungsring mit einer Flasche verbindbar und zum wiederholten Öffnen und Schliessen bestimmt ist. Die nach dem Entfernen des Garantiebandes vorhandenen Ausnehmungen reduzieren die Umfangsspannungen am Rand der Verschlußkappe und erleichtern dadurch das Öffnen und Wiederverschließen der Verschlußkappe.All this is achieved with a bottle cap, which can be connected to a bottle via a fastening ring and is intended for repeated opening and closing. The recesses present after the removal of the guarantee tape reduce the circumferential tension at the edge of the sealing cap and thereby facilitate the opening and reclosing of the cap.

Vorteilhafte Ausgestaltungen des Flaschenverschlusses sind in den Ansprüchen 2 bis 3 beschrieben.Advantageous embodiments of the bottle stopper are described in claims 2 to 3.

Bei dem Flaschenverschluss kann die Verschlußkappe direkt auf den Kopf einer Flasche aufgesetzt werden, wobei die Rastrippe hinter einem radialen Wulst am Flaschenkopf einrastet. Es ist jedoch auch möglich, den Flaschenverschluss so auszugestalten, dass der Verschlußkappenteil mit einem auf einen Flaschenkopf aufsetzbaren Ausgiessteil zusammenwirkt. Dabei ist insbesondere eine Ausgestaltung nach Anspruch 2 zweckmäßig, die den Halt des Verschlußkappenteiles am Ausgiessteil verbessert. Der axiale Stützflansch dient gleichzeitig auch zur Verbeßerung der Garantiefunktion, da er das Abnehmen des Verschlußkappenteiles vom Ausgiessteil erschwert. Hierzu ist insbesondere eine Weiterbildung nach Anspruch 3 von Vorteil.With the bottle cap, the cap can be placed directly on the head of a bottle, the locking rib snapping into place behind a radial bead on the bottle head. However, it is also possible to design the bottle cap so that the cap part interacts with a pouring part that can be placed on a bottle head. In this case, an embodiment according to claim 2 is particularly expedient, which improves the hold of the closure cap part on the pouring part. The axial support flange also serves to improve the guarantee function, since it makes it difficult to remove the cap part from the pouring part. A further development according to claim 3 is particularly advantageous for this.

Die Figuren 1 bis 4 zeigen einen Flaschenverschluss, der gebildet ist aus einem an einem Flaschenkopf 2 angesetzten Ausgiessteil 4 und einem an diesem angeordneten Verschlußkappenteil 6. Der Flaschenverschluss besteht aus Kunststoff.Figures 1 to 4 show a bottle cap, which is formed from a pouring part 4 attached to a bottle head 2 and a cap part 6 arranged thereon. The bottle cap is made of plastic.

Der Ausgiessteil 4 enthält eine Hülse 8 mit einem Innengewinde 10, das mit einem Aussengewinde 12 des Flaschenkopfes 2 zusammenwirkt. Am unteren Ende der Hülse 8 ist über eine Sollbruchstelle 14 eine Garantieband 16 angeformt, das eine innere Rastrippe 18 aufweist, die mit einem Absatz 20 am Flaschenkopf 2 zusammenwirkt. Der Ausgiessteil enthält weiter einen inneren Ausgiessflansch 22 mit einem Ausgiessrand 24, wobei die Oeffnung 26 des Ausgiessflansches 22 im wesentlichen mit der Oeffnung 28 des Flaschenkopfes fluchtet. An den Ausgiessflansch 22 schliesst sich radial nach aussen ein nach oben weisender Rastflansch 30 an, der mit einer aussenliegenden umlaufenden Rastrippe 32 versehen ist. Ferner enthält der Ausgiessteil 4 einen radial weiter aussenliegenden Stützflansch 34, der sich in axialer Richtung erstreckt und einen inneren Konus 36 aufweist.The pouring part 4 contains a sleeve 8 with an internal thread 10 which interacts with an external thread 12 of the bottle head 2. At the lower end of the sleeve 8, a guarantee band 16 is formed via a predetermined breaking point 14, which has an inner locking rib 18 which cooperates with a shoulder 20 on the bottle head 2. The pouring part further contains an inner pouring flange 22 with a pouring rim 24, the opening 26 of the pouring flange 22 being substantially aligned with the opening 28 of the bottle head. The pouring flange 22 is adjoined radially outwardly by an upwardly facing latching flange 30 which is provided with an outer circumferential latching rib 32. The pouring part 4 further contains a support flange 34 lying radially further outward, which extends in the axial direction and has an inner cone 36.

Mit dem Ausgiessteil 4 wirkt der Verschlußkappenteil 6 zusammen, der die eigentliche Verschlußkappe 38 aufweist, die mit einer Einsteckschürze 40 in die Oeffnung 26 des Ausgiessflansches 22 eingreift. Die Verschlußkappe 38 enthält weiter einen äusseren nach unten weisenden Flansch 42, an den sich über eine Sollbruchstelle 44 eine Garantieband 46 anschliesst, das wiederum über eine Sollbruchstelle 48 mit einem Befestigungsring 50 in Verbindung steht. Letzterer enthält auf seiner Innenseite eine umlaufende Rastrippe 52, die mit der Rastrippe 32 des Rastflansches 30 des Ausgiessteiles zusammenwirkt. Weiter enthält der Befestigungsring 50 einen unteren aussenliegenden Konus 54, der sich nach unten verjüngt und mit dem inneren Konus 36 des Stützflansches 34 des Ausgiessteiles 4 zusammenwirkt. Die Anordnung ist so getroffen, dass die Eingriffsstrecke a der Rastrippen 32,52 kleiner ist als die axiale Eingriffsstrecke b der Konen 36,54, so dass beim Zusammensetzen des Verschlußkappenteiles 6 mit dem Ausgiessteil 4 zunächst die Konen 36,54 in Eingriff kommen, bevor die Rastrippen 32,52 verrasten. Dadurch wird einerseits der Kalt des Verschlußkappenteils am Ausgiessteil verbessert und andererseits sichergestellt, dass ein Lösen des Verschlußkappenteiles vom Ausgiessteil 4 erschwert ist.With the pouring part 4, the closure cap part 6 interacts, which has the actual closure cap 38, which engages with an insert apron 40 in the opening 26 of the pouring flange 22. The closure cap 38 also contains an outer downward-pointing flange 42, to which a guarantee band 46 is connected via a predetermined breaking point 44, which in turn is connected to a fastening ring 50 via a predetermined breaking point 48. The latter contains on its inside a circumferential locking rib 52 which interacts with the locking rib 32 of the locking flange 30 of the pouring part. Furthermore, the fastening ring 50 contains a lower outer cone 54, which tapers downwards and interacts with the inner cone 36 of the support flange 34 of the pouring part 4. The arrangement is such that the engagement distance a of the locking ribs 32, 52 is smaller than the axial engagement distance b of the cones 36, 54, so that when the closure cap part 6 is assembled with the pouring part 4, the cones 36, 54 first come into engagement before engage the locking ribs 32.52. This will on the one hand improves the cold of the closure cap part on the pouring part and on the other hand ensures that it is difficult to detach the closure cap part from the pouring part 4.

Das Garantieband 46 des Verschlußkappenteiles 6 läuft nicht vollständig um den Verschlußkappenteil 6 um, sondern wird durch einen Scharnierteil 56 unterbrochen, um den die Verschlußkappe 38 geschwenkt werden kann, wenn das Garantieband 46 entfernt ist. Das Garantieband 46 enthält eine Aufreißlasche 58, die durch einen Sektor der Verschlußkappe 38 gebildet ist und von dieser über einen Spalt 60 getrennt ist. Ein Abreißsteg 62 sichert den Halt der Aufreißlasche 58 an der Verschlußkappe. Die Verschlußkappe 38 enthält einen nach oben vorstehenden Randteil 64, in den die Aufreißlasche 58 integriert ist. Dadurch wird das Erfassen der Aufreißlasche 58 zum Abreißen derselben erleichtert. Ferner ist die Verschlußkappe an der dem Scharnierteil 56 gegenüberliegenden Seite mit einem Griffteil 66 versehen, der durch eine radial nach innen verlaufende Ausnehmung 68 gebildet ist, wobei der obere Rand 70 der Ausnehmung im wesentlichen waagrecht verläuft.The guarantee band 46 of the closure cap part 6 does not completely run around the closure cap part 6, but is interrupted by a hinge part 56 about which the closure cap 38 can be pivoted when the guarantee band 46 is removed. The guarantee tape 46 contains a tear tab 58, which is formed by a sector of the closure cap 38 and is separated from it by a gap 60. A tear-off web 62 ensures that the pull tab 58 is held on the closure cap. The closure cap 38 contains an upwardly projecting edge part 64, in which the tear tab 58 is integrated. This makes it easier to grasp the tear tab 58 in order to tear it off. Furthermore, the closure cap is provided on the side opposite the hinge part 56 with a grip part 66 which is formed by a radially inwardly extending recess 68, the upper edge 70 of the recess being essentially horizontal.

Die Figur 5 zeigt eine weitere Ausbildung eines Flaschenverschlusses, wobei der Verschlußkappenteil 72 direkt an einem Flaschenkopf 74 angeordnet ist. Der Verschlußkappenteil 72 enthält eine Verschlußkappe 76 mit einer in die Oeffnung 78 des Flaschenkopfes 74 eingreifenden Einsteckschürze 80. An den Rand der Verschlußkappe 76 schliesst sich nach unten über eine Sollbruchstelle 82 ein Garantieband 84 an, an das über eine weitere Sollbruchstelle 86 ein Befestigungsring 88 angeformt ist. Dieser enthält eine umlaufende Rastrippe 90, welche einen nach aussen vorstehenden Wulst 92 des Flaschenkopfes untergreift. Das Garantieband 84 enthält wiederum eine Aufreißlasche 94, die durch einen Sektor der Verschlußkappe 76 gebildet ist und über einen Spalt 96 von der übrigen Verschlußkappe getrennt ist. Ein Abreißsteg 98 sichert die Abreißlasche 94 an der Verschlußkappe 76. Die Ausbildung ist so getroffen, dass beim Entfernen des Garantiebandes 84 die Verschlußkappe analog der Ausbildung des Flaschenverschlusses der Figuren 1 bis 4 über einen Scharnierteil mit dem Befestigungsring 88 verbunden bleibt, wenn das Garantieband 84 entfernt ist, so dass die Verschlußkappe aufklappbar ist.FIG. 5 shows a further embodiment of a bottle cap, the cap part 72 being arranged directly on a bottle head 74. The closure cap part 72 contains a closure cap 76 with an insertion apron 80 which engages in the opening 78 of the bottle head 74. At the edge of the closure cap 76, a guarantee band 84 is connected at the bottom via a predetermined breaking point 82, to which a fastening ring 88 is formed via a further predetermined breaking point 86 is. This contains a circumferential locking rib 90 which engages under a bulge 92 of the bottle head which projects outwards. The guarantee tape 84 in turn contains a tear-open flap 94 which is formed by a sector of the closure cap 76 and is separated from the rest of the closure cap via a gap 96. A tear-off bar 98 secures the Tear-off tab 94 on the closure cap 76. The design is such that when the guarantee band 84 is removed, the closure cap remains connected to the fastening ring 88 via a hinge part, analogously to the construction of the bottle closure of FIGS. 1 to 4, when the guarantee band 84 is removed, so that the cap can be opened.

Die Figur 6 zeigt eine weitere Ausbildung des Flaschenverschlusses, wobei die Verschlusskappe 102 in einem äusseren Flansch 104 eine radial nach unten weisende Ausnehmung 106 aufweist, die einen Griffteil 108 bildet. Im Origianlzustand ist die Ausnehmung 106, d.h. der Griffteil 108 durch eine Erweiterung 110 des Garantiebandes 112 verschlossen. Erst nach Entfernen des Garantiebandes 110 ist der Griffteil 108 zugänglich. Der Verschluss kann im übrigen so ausgebildet sein, wie in den obigen Beispielen beschrieben.FIG. 6 shows a further embodiment of the bottle stopper, the stopper cap 102 having a radially downward recess 106 in an outer flange 104, which forms a handle part 108. In the original state, the recess 106, i.e. the handle part 108 is closed by an extension 110 of the guarantee band 112. The grip part 108 is only accessible after the guarantee band 110 has been removed. The closure can otherwise be designed as described in the examples above.
