Description

Die Erfindung bezieht sich auf eine Verschlusskappe aus Kunststoff, insbesondere für einen mit einem Hals versehenen Behälter, wobei der Hals an einem einer Abgabeöffnung gegenüberliegenden Endbereich mindestens einen Haltevorsprung aufweist, mit einem Hauptteil und einem mit diesem in Verbindung stehenden Originalitäts-Sicherungselement, wobei das Hauptteil und das Sicherungselement einstückig ausgebildet und durch mindestens einen brechbaren Steg miteinander verbunden sind.The invention relates to a plastic closure cap, in particular for a container provided with a neck, wherein the neck has at least one holding projection at an end region opposite to a dispensing opening, with a main part and a tamper-evident element connected thereto, the main part and the securing element integrally formed and connected by at least one breakable web.

Als Stand der Technik ist bereits eine derartige Verschlusskappe bekannt ( EP 0 568 288 A1 ), bei welcher das Sicherungselement im unteren Bereich einen hakenartigen Vorsprung aufweist. Dieser Vorsprung liegt im Abstand zum Endbereich des Behälters, so dass eine formschlüssige Verriegelung zwischen der Verschlusskappe und dem Behälter nicht gegeben ist.As the prior art, such a cap is already known ( EP 0 568 288 A1 ), in which the securing element has a hook-like projection in the lower region. This projection is located at a distance from the end region of the container, so that a positive locking between the cap and the container is not given.

Als weiterer allgemeiner Stand der Technik ist es bereits bekannt, dass viele auf dem Markt befindlichen, aus Kunststoff bestehenden Verschlusskappen mit einem Originalitäts-Sicherungselement beispielsweise in Form eines Ringes versehen sind. Dieser Ring wird bei der Erstöffnung ganz oder teilweise vom Hauptkörper der Verschlusskappe getrennt, wodurch dem Benutzer angezeigt wird, dass die Originalität nicht mehr gegeben ist. Anforderungen aus der Sicht des Verbrauchers sind hierbei unter anderem ein zuverlässiges Anzeigen einer erfolgten Öffnung, das heißt der nicht mehr vorhandenen Originalität, wobei außerdem die Handhabung des Verschlusses nicht erschwert sein soll.As a further general state of the art, it is already known that many existing on the market, plastic caps are provided with a tamper-evident element, for example in the form of a ring. This ring is completely or partially disconnected from the main body of the cap during initial opening, indicating to the user that originality is no longer present. Requirements from the point of view of the consumer are, inter alia, a reliable indication of a successful opening, that is, the no longer present originality, in addition, the handling of the closure should not be difficult.

In einer Variante dieses bekannten Standes der Technik wird der Hauptkörper der Verschlusskappe in einem Stück mit dem fertig angeformten Originalitäts-Sicherungselement produziert. Die Verbindung besteht aus dünnen Brücken zwischen Hauptkörper und Sicherungselement, welche beim Öffnen des Verschlusses reißen. Das Sicherungselement verbleibt dabei je nach Ausführung am Gewindehals oder an der Verschlusskappe.In a variant of this known prior art, the main body of the closure cap is produced in one piece with the finished molded originality security element. The connection consists of thin bridges between the main body and fuse element, which tear when opening the closure. The securing element remains depending on the design of the threaded neck or on the cap.

Nachteilig ist bei diesem bekannten Stand der Technik, dass die Geometrie der Rückhalteelemente nicht frei wählbar ist, sondern je nach eingesetztem Rohstoff Einschränkungen unterliegt. Das begünstigt Fehlfunktionen wie Abreißen des Ringes bereits beim Verschließen oder Verbleib des Ringes an der Verschlusskappe beim Öffnen und erfordert eine genaue Abstimmung der Stärke der Brücken, was das Prozessfenster einschränkt. Des Weiteren ist ein derartig angeformtes Sicherungselement oft limitierender Faktor der Produktionsgeschwindigkeit.A disadvantage of this known prior art that the geometry of the retaining elements is not arbitrary, but depending on the raw material restrictions subject. This favors malfunctions such as tearing of the ring already during closing or retention of the ring on the cap when opening and requires a precise adjustment of the strength of the bridges, which limits the process window. Furthermore, such a molded fuse element is often limiting factor of production speed.

Nach einer weiteren, allgemein bekannten Variante werden Hauptkörper der Verschlusskappe und das Originalitäts-Sicherungselement getrennt von einander ausgebildet, einzeln produziert und dann mit einander vormontiert. Erst nach Aufbringen auf den Hals eines Behälters ist die Einheit Behälter - Verschlusskappe komplettiert und die Montage vollständig beendet. Nachteilig ist bei diesem bekannten Stand der Technik die getrennte und damit kostenaufwendige Herstellung der beiden Teile, die getrennte Lagerhaltung, die erforderliche Vormontage beider Teile und die Möglichkeit einer fehlerhaften Verbindung dieser beiden Teile.According to another, well-known variant main body of the cap and the tamper-evident element are formed separately from each other, produced individually and then preassembled with each other. Only after application to the neck of a container, the unit container cap is completed and the assembly is completed. A disadvantage of this known prior art, the separate and therefore costly production of the two parts, the separate storage, the required pre-assembly of both parts and the possibility of incorrect connection of these two parts.

Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, eine Verschlusskappe der eingangs genannten Art zu schaffen, welche einfacher und kostensparender bei der Herstellung ist, die Montage vereinfacht und eine leichte Handhabung der Verschlusskappe gewährleistet.In contrast, the object of the present invention is to provide a cap of the type mentioned, which is easier and more cost-effective in the production, simplifies the installation and ensures easy handling of the cap.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an die Unterseite des Sicherungselements einstückig ein Bund anschließt, der zur Bewegung von mindestens einem Bereich des Sicherungselements aus einer Offenstellung in eine den Haltevorsprung des Endbereichs hintergreifende Schließstellung ausgebildet ist. Hierdurch ergibt sich der Vorteil einer schnelleren Produktion mit einem größeren Prozessfenster. Die Herstellung ist billiger und einfacher als die zum Stand der Technik zählende zweiteilige Lösung oder die anderen bekannten Varianten. Darüber hinaus sind geringere vertikale Kräfte zum Verschließen notwendig.This object is achieved in that integrally connected to the underside of the securing element a collar, which is designed for movement of at least a portion of the securing element from an open position into a retaining projection of the end portion engaging behind closed position. This results in the advantage of faster production with a larger process window. The production is cheaper and simpler than the prior art two-part solution or the other known variants. In addition, lower vertical forces are necessary for closing.

In weiterer Ausgestaltung der Erfindung kann der Bund dadurch zur Bewegung des Bereichs des Sicherungselements in die Schließstellung ausgebildet sein, dass er in Richtung der Achse verschiebbar ist und dabei den vorgenannten Bereich beaufschlagt.In a further embodiment of the invention, the collar can thereby be designed for movement of the region of the securing element in the closed position, that it is displaceable in the direction of the axis and thereby acts on the aforementioned area.

In weiterer Ausgestaltung der Erfindung kann nach Aufschieben des Bundes auf das Sicherungselement mindestens eine Rastnase als Bereich des Sicherungselements aus einer Montagestellung in eine den Haltevorsprung des Endbereichs hintergreifende Sperrstellung bewegt ist. Die Rastnase kann hierbei eine beliebige Geometrie aufweisen und an die jeweils vorliegende geometrische Situation im Endbereich des Behälters angepasst werden.In a further embodiment of the invention can be moved as a region of the securing element from an assembly position into a locking projection of the end portion engaging behind locking position after pushing the federal government on the securing element at least one latching lug. In this case, the latching lug can have any desired geometry and can be adapted to the respectively present geometric situation in the end region of the container.

Nach einem anderen Merkmal der Erfindung kann das Sicherungselement mehrere Rastnasen über den Umfang verteilt aufweisen. Weiterhin können über den Umfang des Hauptteils verteilt an dessen Endbereich mehrere brechbare Stege mit dem Sicherungselement in Verbindung stehen.According to another feature of the invention, the securing element may have a plurality of locking lugs distributed over the circumference. Furthermore, distributed over the circumference of the main part at the end region of several breakable webs with the fuse element in connection.

Eine besonders vorteilhafte Lösung ergibt sich in weiterer Ausgestaltung der Erfindung darin, dass der Bund eine Länge aufweist, welche in etwa gleich der gesamten Länge des Sicherungselements und der brechbaren Stege ist. Hierdurch umgibt der Bund nach Beendigung der Montage in voller Länge das Originalitäts-Sicherungselement.A particularly advantageous solution results in a further embodiment of the invention in that the collar has a length which is approximately equal to the entire length of the securing element and the breakable webs. As a result, the collar surrounds the originality security element after completion of the assembly in full length.

Nach einem weiteren Merkmal der Erfindung kann der Bund innenseitig im oberen Bereich eine Schulter aufweisen, welche in Schließstellung den Außenumfang eines oberen Ringes des Sicherungselements umfasst. Weiterhin kann der Bund im unteren Bereich eine umlaufende Nase aufweisen, welche in Schließstellung das Sicherungselement umgreift. Hierdurch ist das Originalitäts-Sicherungselement in voller Länge in Montagestellung von dem Bund umschlossen.According to a further feature of the invention, the collar may have on the inside in the upper region a shoulder, which in the closed position comprises the outer periphery of an upper ring of the securing element. Furthermore, the federal government in the lower region may have a circumferential nose, which surrounds the securing element in the closed position. As a result, the originality-securing element is enclosed in full length in the assembled position of the federal government.

In weiterer Ausgestaltung der Erfindung kann jede Rastnase über eine im unteren Bereich liegende Knickstelle aus der Montagestellung in die Sperrstellung bewegbar sein. Jede Rastnase kann beispielsweise im Querschnitt etwa dreieckig ausgebildet werden, wobei jedoch auch andere Querschnittsgeometrien in Anpassung an den mit einem Originalitätsverschluss zu versehenden Behälter denkbar sind.In a further embodiment of the invention, each locking lug can be moved from the mounting position into the blocking position via a kink point located in the lower region. Each locking lug can be formed approximately triangular in cross section, for example, but other cross-sectional geometries in adaptation to be provided with a tamper-evident container are conceivable.

Bei einer Verschlusskappe, bei welcher das Hauptteil ein Innengewinde aufweist, welches mit einem Außengewinde oberhalb des Endbereichs des Behälterhalses verschraubt ist, besteht erfindungsgemäß die Möglichkeit, dass die brechbaren Stege und das Sicherungselement an den Innengewindebereich des Hauptteils anschließen. Dieser Anschluss kann direkt oder über ein Zwischenstück erfolgen.In the case of a closure cap in which the main part has an internal thread which is screwed to an external thread above the end region of the container neck, it is possible in accordance with the invention for the breakable webs and the securing element to adjoin the internally threaded region of the main part. This connection can be made directly or via an intermediate piece.

In weiterer Ausgestaltung der Erfindung kann der obere Abschlussbereich des Hauptteils innenseitig eine umlaufende Schulter aufweisen, wobei der Abschlussrand des Behälters zwischen der umlaufenden Schulter und einer umlaufenden Innenkappe des Abschlussbereichs des Hauptteils eingebettet ist. In dem Zwischenraum zwischen der Innenkante und der Schulter kann eine Dichtlippe auf der Unterseite des Hauptteils angeordnet sein, um eine einwandfreie Abdichtung der Abgabestelle des Behälters zu ermöglichen.In a further embodiment of the invention, the upper end region of the main part on the inside have a circumferential shoulder, wherein the end edge of the container between the circumferential shoulder and a circumferential inner cap of the end portion of the main part is embedded. In the space between the inner edge and the shoulder, a sealing lip may be arranged on the underside of the main part in order to allow a perfect sealing of the discharge point of the container.
