Abstract

A plastic closure cap, especially for glass containers, includes a lid part to be pulled off exposing a seal or an opening. A sleeve part surrounds a bottle neck of the container. Grippers are secured on the sleeve part and are pivotal at material weak points at the sleeve part. The grippers abut one another in flush fashion in a closing position and are joined to make a closed surface encompassing the bottle neck. The grippers have sides pointing toward one another. The grippers are rectangular as seen in a plan view and curved as seen in cross section. Tabs are associated with the grippers. The sides of the grippers and the tabs face one another and have alternating profiling mutually complementing one another in the closing position. The sides of the grippers are beveled toward the inside and overlap one another in the closing position.

Description

Die Erfindung betrifft eine Verschlußkappe aus Kunststoff, insbesondere für Glasbehälter, mit an einem die Behälteröffnung übergreifenden Mantelteil über Materialschwachstellen angeschlossenen, in eine senkrechte Lage verschwenkbaren Greifersegmenten mit sich in Schließstellung an den Zueinanderweisenden Seitenflächen gegenseitig ergänzender Profilierung.The invention relates to a closure cap made of plastic, in particular for glass containers, with gripper segments connected to a jacket part spanning the container opening via material weak points and pivotable into a vertical position with mutually complementary profiling in the closed position on the mutually facing side surfaces.

Aus der CH-A-373 975 ist ein Kronenverschluß bekannt, bei dem von einem Boden über eine Ringnut ausgehende Segmente über in deren Seitenflächen vorhandene Federn und Nuten in geschlossenem Zustand des Kronenkorkens miteinander verbunden sind. Das Öffnen dieses Verschlusses erfolgt entweder mit Hilfe eines Kronenverschlußöffners über eine am Rande des Verschlußteils vorgesehene Sollbruchstelle oder über einen Abreißlappen und einen in den Verschluß integrierten Abreißring. Das Andrücken der Segmente an den Flaschenhals erfolgt aus einer etwa unter 30° geneigten Lage. Das Entformen derart unter einem Winkel von 30° hergestellter Verschlußkappen erfordert jedoch bei deren Herstellung aufgrund der Hinterschneidungen und Nuten der Segmente einen erheblichen Aufwand.From CH-A-373 975 a crown closure is known, in which segments starting from a base via an annular groove are connected to one another in the closed state of the crown cap by means of tongues and grooves in the side surfaces thereof. This closure is opened either with the aid of a crown closure opener via a predetermined breaking point provided on the edge of the closure part or via a tear-off tab and a tear-off ring integrated in the closure. The segments are pressed against the bottle neck from a position inclined at approximately 30 °. The demolding closure caps produced in this way at an angle of 30 °, however, require considerable effort in their manufacture due to the undercuts and grooves in the segments.

Eine Verschlußkappe aus Kunststoff, insbesondere für Injektions- und Infusionsfläschchen, ist in der DE-U 88 05 665 beschrieben. Diese Verschlußkappe besitzt in der Ausgangslage horizontale, gewölbte, rechteckige Greifersegmente. Mit der vorgesehenen Ausbildung und Anordnung der Greifersegmente ist eine homogene Ausbildung des Greiferschließteils nicht möglich, da die Seitenflächen der Greifersegmente nicht überlappen, sondern nur stumpf aneinanderstoßen. Wenn Materialquetschungen im Bereich der Anschlußstelle an das Mantelteil vermieden werden sollen, ist ein bestimmter Abstand zwischen den Segmenten erforderlich. Die Arretierung der gegen den Flaschenhals geschwenkten Segmente kann demzufolge auch nicht durch gegenseitiges Verschweißen erfolgen, sondern muß über ein separates Sicherungselement (Sicherungsring) erfolgen. Eine kraftschlüssige Verbindung wird hier ebensowenig wie bei der Lösung gemäß der schweizerischen Patentschrift vorgenommen.A closure cap made of plastic, in particular for injection and infusion bottles, is described in DE-U 88 05 665. In the starting position, this cap has horizontal, curved, rectangular gripper segments. With the intended design and arrangement of the gripper segments, a homogeneous design of the gripper closing part is not possible since the side surfaces of the gripper segments do not overlap, but only abut each other. If crushing of material in the area of the connection point to the jacket part is to be avoided, a certain distance between the segments is necessary. The segments pivoted against the bottle neck can therefore not be locked by mutual welding, but must be done by means of a separate securing element (securing ring). A non-positive connection is made here just as little as with the solution according to the Swiss patent specification.

Der Erfindung liegt die Aufgabe zugrunde, eine Verschlußkappe aus Kunststoff, insbesondere für Glasbehältnisse, mit an einem Mantelteil über Materialschwachstellen angeschlossenen, in eine senkrechte Lage schwenkbaren Greifersegmenten mit sich in Schließstellung an den zuneinanderweisenden Seitenflächen gegenseitig ergänzender Profilierung zu schaffen, die, ausgehend von einer rationell gefertigten Verschlußkappe mit in der Ausgangslage waagerechten Greifersegmenten, deren innige, eine geschlossene Außenfläche bildende Verbindung in der senkrechten Schließstellung ermöglicht.The invention has for its object a closure cap made of plastic, in particular for glass containers, with gripper segments connected to a jacket part via material weak points and pivotable into a vertical position with one another in the closed position on the mutually facing side surfaces to create additional profiling, which, starting from a rationally manufactured closure cap with horizontal gripper segments in the starting position, enables its intimate connection to form a closed outer surface in the vertical closed position.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einer Verschlußkappe der aufgezeigten Gattung die Seitenflächen der Greifersegmente abgeschrägt sind und sich dadurch in Schließstellung gegenseitig überlappen, während die Materialschwachstelle zwischen dem Mantelteil und dem Greifersegment zum jeweiligen Randbereich des Greifersegments hin entweder durch eine Materialanhäufung geschlossen ist oder durch eine Einkerbung freigehalten ist. Nach einer bevorzugten Ausgestaltung der Erfindung sind die Greifersegmente in Schließstellung im Bereich ihrer überlappenden Seitenflächen und sich gegenseitig ergänzenden Profilierungen durch Ultraschall miteinander verschweißt. In einer weiteren Ausgestaltung der Erfindung weisen die Greifersegmente nach innen gerichtete, den Flaschenhals untergreifende Greifkanten auf und bilden in Schließstellung ein unverlierbares Schließteil, wobei die Profilierung der Greifersegmente aus sich wechselseitig ergänzenden, formschlüssig ineinandergreifenden Haken und Aufnahmen bestehen kann. Es ist zweckmäßig, wenn die Greifersegmente in Ausgangsstellung horizontal verlaufend an dem Mantelteil angeformt sind. Besonders vorteilhaft ist es, die Materialschwachstelle zwischen dem Mantelteil und den Greifersegmenten am Außen- und Innenumfang mit einer angeformten Fase zu versehen. Bei einer besonderen Ausführung der Erfindung sind die Greifersegmente in der Draufsicht rechteckig und im Querschnitt bogenförmig ausgebildet, wobei an den Greifersegmenten eine Lasche angeformt ist.This object is achieved in that the side surfaces of the gripper segments are chamfered in a closure cap of the type shown and thereby overlap each other in the closed position, while the material weak point between the jacket part and the gripper segment to the respective edge region of the gripper segment is either closed by a material accumulation or is kept clear by a notch. According to a preferred embodiment of the invention, the gripper segments are welded to one another in the closed position in the region of their overlapping side surfaces and mutually complementary profiles. In a further embodiment of the invention, the gripper segments have inwardly directed gripping edges which grip under the bottle neck and form a captive locking part in the closed position, wherein the profiling of the gripper segments can consist of mutually complementary, form-fitting interlocking hooks and receptacles. It is expedient if the gripper segments are horizontally formed on the casing part in the starting position. It is particularly advantageous to provide the material weak point between the jacket part and the gripper segments on the outer and inner circumference with a molded bevel. With a special one According to an embodiment of the invention, the gripper segments are rectangular in plan view and arc-shaped in cross-section, a tab being formed on the gripper segments.

Nach einer weiteren Ausbildung der Erfindung ist im Mantelteil ein eine Dichtung oder eine Öffnung freilegendes Deckelteil vorgesehen, das innen eine ringförmige, nach außenstehende Klemmlippe besitzt, die auf ihrem Umfang mit gewölbten, nach außenstehenden, zum Lippenanfang des Deckelinnenteils auslaufenden Ausbuchtungen versehen ist. Am Deckelteil kann außen ein Ring angeformt sein, der am Innenumfang zylindrisch ausgeführt ist und am Außenumfang bogenförmig und/oder fasenförmig nach innen zum zylindrischen Innenumfang ausläuft.According to a further embodiment of the invention, a cover part which exposes a seal or an opening is provided in the jacket part and has an annular, outwardly projecting clamping lip on the inside, which is provided on its circumference with curved, outwardly projecting bulges which run out to the beginning of the inside part of the cover. A ring can be formed on the outside of the cover part, which is cylindrical on the inner circumference and runs out in an arcuate and / or chamfer shape on the outer circumference inwards to the cylindrical inner circumference.

Die Verschlußkappe aus Kunststoff weist an ihrem einen Flaschenhals 3 (Fig. 4) umgebenden Mantelteil 2 (Fig. 1 - 5) ein unter einem hinterschnittenen Rand 4 (Fig. 4) des Flaschenhalses 3 greifendes Schließteil 9 (Fig. 4 und 5) auf und besitzt ein aufziehbares, eine Dichtung 5 (Fig. 4) freilegendes Deckelteil 6 (Fig. 4 und 5).The closure cap made of plastic has on its shell part 2 (FIGS. 1-5) surrounding a bottle neck 3 (FIG. 4) a closing part 9 (FIGS. 4 and 5) which engages under an undercut edge 4 (FIG. 4) of the bottle neck 3 and has an expandable cover part 6 (FIGS. 4 and 5) which exposes a seal 5 (FIG. 4).

Das Schließteil 9 (Fig. 4 und 5) ist dabei von so vielen in dem Mantelteil 2 (Fig. 1 - 5) angeordneten Greifern 8 und Greifkanten 8b gebildet, daß die in der Schließstellung hinter den Flaschenhalsrand 4 (Fig. 4) verhakenden Greifkanten und Greifer flächenmäßig und fugendicht verbunden sind (Fig. 5).The closing part 9 (FIGS. 4 and 5) is formed by so many grippers 8 and gripping edges 8b arranged in the jacket part 2 (FIGS. 1-5) that the gripping edges hooking behind the bottle neck edge 4 (FIG. 4) in the closed position and grippers are connected in terms of area and joints (Fig. 5).

Gemäß der Ausführung nach Fig. 1 - 5 sind die Greifer 8 und Greifkanten 8b an über angeformte Materialschwachstellen 7 (Fig. 1 - 5) mit dem Mantel 2 einstückig so verbunden, daß beim Schließen aus der horizontalen in die vertikale Stellung eine geschlossene Materialschwachstelle, insbesondere an den Punkten 7b (Fig. 1 und 3) gewährleistet ist, ohne daß es zu Materialquetschungen kommt. Ebenso kann durch Einkerbung an den Punkten 7a (Fig. 2) eine Materialquetschung vermieden werden.According to the embodiment according to FIGS. 1-5, the grippers 8 and gripping edges 8b are integrally connected to the jacket 2 via molded-on material weak points 7 (FIGS. 1-5) in such a way that when closed from the horizontal to the vertical position, a closed material weak point, especially at points 7b (Fig. 1 and 3) is guaranteed without crushing the material. Likewise, notching at points 7a (FIG. 2) can avoid crushing of material.

Die in diesen angeformten Materialschwachstellen 7 gegen den Flaschenhals 3 (Fig. 4) schwenkbaren Greifer 8 sind so ausgebildet, daß sie bei Beendigung des Schließvorgangs flächenmäßig und fugendicht zu einer kraft- und formschlüssigen, geschlossen um den Flaschenhals 3 (Fig. 4) umlaufenden Fläche 9 (Fig. 5) verbunden sind. Die Greifer können in verschiedenen geometrischen Formen ausgebildet sein.The formed in this material weak points 7 against the bottle neck 3 (Fig. 4) pivotable gripper 8 are designed so that when the closing process is finished, they are surface-tight and joint-tight to form a non-positive and form-fitting surface that is closed around the bottle neck 3 (Fig. 4) 9 (Fig. 5) are connected. The grippers can be designed in various geometric shapes.

Das Deckelteil 6 (Fig. 4 und 5) ist mit einem Griffteil 10 zum Herausziehen des Deckelteils aus der Verschlußkappe ausgestattet. Das Griffteil ist am Innenumfang 11 (Fig. 4) zylindrisch ausgeführt und läuft im Außenumfang 11a bogen- und fasenförmig oder in deren Kombination nach innen zum Innenumfang aus.The cover part 6 (FIGS. 4 and 5) is equipped with a handle part 10 for pulling the cover part out of the closure cap. The grip part is cylindrical on the inner circumference 11 (FIG. 4) and runs in the outer circumference 11a in the form of an arc and bevel or in a combination thereof inwards to the inner circumference.

Das Deckelteil 6 ist an der Verschlußkappe 1 so angeformt, daß es im Deckelinnenteil 15 (Fig. 4) eine nach unten oder zur Seite stehende, in verschiedenen geometrischen Formen ausgebildete, dünnwandige Klemmlippe 14 (Fig. 4) besitzt, die sich beim Verschließungsvorgang der Kappe auf dem Flaschenhals nach unten oder oben umbiegt und somit klemmend und dichtend am Kappenunterboden oder im Flascheninnenteil anliegt.The lid part 6 is formed on the closure cap 1 so that it has a thin-walled clamping lip 14 (FIG. 4) in the inner lid part 15 (FIG. 4) which is formed at the bottom or to the side and is formed in various geometrical shapes and which becomes apparent during the closing process Bends the bottle neck down or up on the bottle neck and thus fits tightly against the bottom of the cap or inside the bottle.

Fig. 1 und 2 zeigen die hergestellte Ausgangsform der Verschlußkappe, bei der die gewölbten Greifer 8 in einer waagerechten Ebene liegen und nach außen vom Mantelteil 2 abstehen. Dabei kann man an den Punkten 7a (Fig. 2) die notwendigen Einkerbungen oder an den Punkten 7b die Materialanhäufungen (Fig. 1 und 3) sehen, so daß es beim Verschließungsvorgang zu keiner Materialquetschung kommt.1 and 2 show the initial shape of the closure cap, in which the curved grippers 8 lie in a horizontal plane and protrude outwards from the casing part 2. The necessary notches can be seen at points 7a (FIG. 2) or the material accumulations at points 7b (FIGS. 1 and 3), so that there is no crushing of the material during the closing process.

Zum Verschließen des Flaschenhalses 3 wird die Verschlußkappe auf denselben aufgesetzt und dann werden die Greifer 8 über ihre entsprechenden vorgeformten Materialschwachstellen 7 (Fig. 4) nach unten gegen den Flaschenhals 3 gedrückt. Diese Vorformung ist notwendig, damit es beim Schwenken aus der horizontalen in die vertikale Stellung zu keinem Weißbruch kommt. Ebenso kommt es in der Schließstellung zu einer geschlossenen und fugendichten, um den Flaschenhals umlaufenden Fläche 9 (Fig. 5).To close the bottle neck 3, the closure cap is placed on it and then the grippers 8 are pressed downward against the bottle neck 3 via their corresponding preformed material weak points 7 (FIG. 4). This preforming is necessary so that there is no white break when swiveling from the horizontal to the vertical position. Likewise, in the closed position there is a closed and joint-tight surface 9 surrounding the bottle neck (FIG. 5).

Die Verschlußkappe nach Fig. 3 - 5 entspricht im Grundaufbau und Prinzip der Verschlußkappe nach Fig. 1 und 2. Deshalb sind für gleiche Teile auch diesselben Bezugszahlen verwendet worden. Aus ihnen sind deutlich die angeformte Materialschwachstelle 7 und die an den Punkten 7b (Fig. 1 und 3) ausgeführten Materialanhäufungen zu ersehen. In Fig. 1 und 2 ist der wechselseitige Absatz 8a der Laschen sichtbar, der notwendig ist, damit sich im Verschlußzustand die jeweils nebeneinanderliegenden Greifer 8 überlappen und somit notwendigerweise mit Ultraschall verschweißt werden können, so daß es zu einer flächenmäßig und fugendicht geschlossenen, um den Flaschenhals 3 umlaufenden Fläche 9 (Fig. 4 und 5) kommt.3 - 5 corresponds in its basic structure and principle to the closure cap according to FIGS. 1 and 2. Therefore, the same reference numbers have been used for the same parts. The molded-on material weak point 7 and the material accumulations carried out at points 7b (FIGS. 1 and 3) can be clearly seen from them. 1 and 2, the mutual shoulder 8a of the tabs is visible, which is necessary so that in the closed state the grippers 8 lying next to one another overlap and can therefore necessarily be welded with ultrasound, so that it comes to a surface and joint-tight, around the bottle neck 3 circumferential surface 9 (Fig. 4 and 5).

Ebenso können die Greifer 8 so ausgebildet werden, daß es zu nebeneinanderliegenden Greifern 8 mit wechselseitigen Arretierungshaken 12 und Arretierungsaufnahmen 13 (Fig. 3 und 5) in verschiedenen geometrischen Formen sowie deren Kombination mit dem wechselseitigen Überlappen der Laschen kommt, um eine um den Flaschenhals 3 umlaufende Fläche 9 (Fig. 4 und 5) auszubilden.Likewise, the grippers 8 can be designed in such a way that there are grippers 8 lying next to one another with mutual locking hooks 12 and locking receptacles 13 (FIGS. 3 and 5) in various geometric shapes and their combination with the mutual overlapping of the tabs in order to create a neck 3 to form peripheral surface 9 (FIGS. 4 and 5).
