Description

Die Erfindung betrifft ein Behältnis, insbesondere Kunststoff-Ampulle gemäß der Merkmalsausgestaltung des Oberbegriffes des Patentanspruchs 1.The invention relates to a container, in particular a plastic ampoule according to the feature configuration of the preamble of patent claim 1.

Durch die DE 42 32 305 C1 ist eine Kappe für Behältnisse, insbesondere im Blasformverfahren aus Kunststoff hergestellte und in der Form gefüllte sowie verschlossene Flaschen, auch in Ampullenform, bekannt, mit einem Hals, auf den eine Kappe aufsetzbar ist, wobei die Kappe im Anschluß an den den Hals aufnehmenden Abschnitt einen mit letzterem einstückig ausgebildeten Abschnitt aufweist, der als Tropfer ausgebildet ist. Dabei beschreibt die genannte Patentschrift als bekannte Lösungen Flaschen solcher Art, deren mit einem Außengewinde versehener Hals an seinem freien Ende durch ein einstückig mit dem Hals ausgebildetes Verschlußteil verschlossen ist, wobei eine auf den Hals aufgeschraubte Kappe innen mit einem zentral angeordneten Dorn versehen ist, mit dem das Verschlußteil durchstoßen werden kann. Wird nach dem Durchstoßen des Verschlußteils die Kappe abgenommen, dann kann durch die im Verschlußteil gebildete Öffnung die sich in der Flasche befindende Flüssigkeit abgegeben werden. Hierbei hat sich jedoch gezeigt, dass es bei einem nicht optimal ausgeformten Gewinde des Flaschenhalses und/oder der Kappe oder auch einem nicht optimal ausgeformten Dorn dazu kommen kann, dass die mit dem Dorn eingestochene Öffnung schräg bezüglich der Längsachse verläuft oder dass nach einer Entnahme einer Teilmenge und einem anschließenden Aufschrauben der Kappe eine zweite Öffnung eingestochen wird, was zur Folge hat, dass die Flüssigkeit in einer von der Längsachse abweichenden Richtung gegebenenfalls an mehreren Stellen austritt, was für den sinnfälligen Gebrauch der Lösung sehr störend ist. Demgemäß schlägt die vorgestellte Patentlösung vor, dank des als Tropfer ausgebildeten Abschnitts der Kappe die Dosierung bei der Abgabe des flüssigen Inhalts der Flasche nicht mittels einer vom Flaschenhals gebildeten Öffnung, sondern mittels des Tropfers der Kappe vorzunehmen, was einen störungsfreien Anwendungsgebrauch zuläßt.By the DE 42 32 305 C1 is a cap for containers, in particular in the blow molding process made of plastic and filled in the form and sealed bottles, also in ampoule form, known, with a neck on which a cap can be placed, wherein the cap following the neck receiving portion of a having integrally formed with the latter portion which is formed as a dropper. This patent describes known solutions as bottles of this type, which is provided with an externally threaded neck at its free end by an integrally formed with the neck closure member, wherein a screwed onto the neck cap is internally provided with a centrally disposed mandrel, with the closure part can be pierced. If the cap is removed after piercing the closure part, the liquid in the bottle can be dispensed through the opening formed in the closure part. In this case, however, it has been found that it can happen that the pierced with the mandrel at a not optimally shaped thread of the bottle neck and / or the cap or a non-optimally shaped mandrel Opening obliquely with respect to the longitudinal axis or that after removal of a subset and then screwing the cap, a second opening is pierced, which has the consequence that the liquid in a deviating from the longitudinal axis direction optionally exits at several points, which is obvious Use of the solution is very annoying. Accordingly, the proposed patent solution proposes, thanks to the trained as a dropper portion of the cap, the dosage in dispensing the liquid content of the bottle not by means of an opening formed by the bottle neck, but by means of the dropper of the cap, which allows a trouble-free application use.

Durch die DE 195 80 104 T1 ist eine vergleichbare Behältnislösung bekannt mit einem luftdicht abgeschlossenen Behälter, der mit einer Abdeckkappe versehen ist, wobei ein in der Kappe angebrachter Dorn zum Durchstoßen einer Membran am Halsteil des Behälters dient. Der hohle Dorn bildet eine Art Aufsatz aus, der einen Austragsdurchgangsweg definiert, um dergestalt eine geregelte Flüssigkeitsentnahme sicher zu stellen. Hierfür durchstößt der Dorn die Membran und nach dem Entfernen eines ersten Kappenteils wird der Dorn über das zweite Kappenteil in der Membran zurückgehalten, um dergestalt eine geregelte Spender- bzw. Ausgabeöffnung für das Behältnis zur Verfügung zu stellen. Das erste Kappenteil kann dann erneut dem Verschließen der Spender- bzw. Abgabeöffnung für den Behältniskörper des Behälters dienen. Die Herstellung der bekannten Behältnislösungen ist zumindest teilweise als aufwendig und mithin kostenintensiv anzusehen.By the DE 195 80 104 T1 a comparable container solution is known with an airtight container provided with a cap, wherein a cap mounted in the mandrel for piercing a membrane on the neck portion of the container is used. The hollow mandrel forms a kind of attachment which defines a discharge passageway so as to ensure a controlled liquid withdrawal. For this purpose, the mandrel penetrates the membrane and after removal of a first cap portion of the mandrel is retained on the second cap member in the membrane to provide such a regulated dispensing or dispensing opening for the container. The first cap portion may then again serve to close the dispensing or dispensing opening for the container body of the container. The preparation of the known container solutions is at least partially regarded as expensive and therefore costly.

Die US 5 954 233 A betrifft ein gattungsgemäßes Behältnis, insbesondere im Blasformverfahren hergestellte und in der Form gefüllte sowie geschlossene Kunststoff-Ampulle, mit einem an einen Behältniskörper sich anschließenden Halsteil, auf das ein erstes Kappenteil aufschraubbar ist und mit einem zweiten Kappenteil, das mindestens eine Ausnehmung aufweist und das sich zumindest teilweise zwischen dem ersten Kappenteil und dem Halsteil erstreckt und das mit einer mindestens eine Öffnung aufweisenden Öffnungseinrichtung zum Öffnen des Behältniskörpers versehen ist, die mittels des ersten Kappenteils verschließbar ist, wobei mittels des Aufschraubvorganges des ersten Kappenteiles dieses das zweite Kappenteil derart mitnimmt, dass die Öffnungseinrichtung die Öffnung des Behältniskörpers veranlasst, wobei nach Abschrauben des ersten Kappenteils ein Verschlussteil desselben die Öffnung der Öffnungseinrichtung freigibt, wobei das zweite Kappenteil am Halsteil verbleibt, wobei Mitnehmerelemente des ersten Kappenteils, die am zweiten Kappenteil angreifen, eine drehende Mitnahmebewegung für den Aufschraubvorgang ermöglichen und die Mitnahmebewegung veranlassen, und wobei nach Eingriff des zweiten Kappenteils am Halsteil das erste Kappenteil bei dessen Abschraubvorgang die Öffnung freigibt.The US 5,954,233 A relates to a generic container, in particular produced by blow molding and filled in the mold and closed plastic ampoule, with a subsequent to a container body Halsteil on which a first cap member is screwed and with a second cap portion, which has at least one recess and which extends at least partially between the first cap portion and the neck portion and which is provided with at least one opening having opening means for opening the container body, the can be closed by means of the first cap part, wherein the second cap member entrains by means of the Aufschraubvorganges of the first cap part, that the opening means causes the opening of the container body, wherein after unscrewing the first cap part thereof a closure part of the opening of the opening device releases, the second cap part on Neck part remains, with cam elements of the first cap member, which engage the second cap member, allow a rotating entrainment movement for the Aufschraubvorgang and cause the entrainment movement, and wherein after engagement of the second capping partly on the neck part, the first cap part in the unscrewing the opening releases.

Für einen Öffnungsvorgang bei der bekannten Behältnislösung sind neben einer Rampenführung zwischen Rampenteilen des ersten Kappenteiles und des zweiten Kappenteiles, die betätigt eine Längszustellung des zweiten Kappenteils in eine Rastposition auf dem Halsteil des Behältnisses bewirken, was mit einem entsprechenden Kraftaufwand bei der Betätigung einhergeht, noch stegartig vorspringende Eingriffsteile am Halsteil vorhanden, die in zugeordnete Ausnehmungen des zweiten Kappenteils eingreifen für dessen drehfeste Festlegung am Halsteil, was einen Öffnungsvorgang des Behältnisses erlaubt in beiden möglichen Drehrichtungen des ersten Kappenteils bei dessen Aufschraub- oder Abschraubvorgang auf das bzw. von dem Behältnis. Aufgrund der angesprochenen Teilevielfalt bei der bekannten Behältnislösung ist deren Herstellung entsprechend aufwendig.For an opening operation in the known container solution are in addition to a ramp guide between ramp parts of the first cap member and the second cap member, the actuation effect a longitudinal delivery of the second cap portion in a detent position on the neck portion of the container, which is associated with a corresponding force during the operation, nor web-like projecting engagement parts on the neck portion present, which engage in associated recesses of the second cap portion for the rotationally fixed fixing on the neck portion, which allows an opening operation of the container in both possible directions of rotation of the first cap portion in its unscrewing or unscrewing on or from the container. Due to the mentioned variety of parts in the known container solution whose production is correspondingly expensive.

Die US 5 462 200 A zeigt gleichfalls ein hermetisch verschlossenes Behältnis, dessen Halsteil an seiner freien Stirnseite über eine Membran verschlossen ist. Zum Öffnen dieser Membran dient ein Eingriffsdorn, der einen fluiddurchlässigen Medienkanal aufweist und der Bestandteil eines zweiten Kappenteils ist, das zum Öffnen des Halsteils an dessen freier Stirnseite mit der Membran eine axiale Zustellbewegung erfährt, sofern das erste Kappenteil das zweite Kappenteil übergreifend auf das Behältnis aufgeschraubt wird. Ein im ersten Kappenteil in Längsachse des Behältnisses angeordneter Verschlussdorn verschließt den Medien- oder Fluidkanal des zweiten Kappenteils und gibt letzteren frei, sobald das erste Kappenteil vom Behältnis abgeschraubt und insofern entfernt ist. Auch bei dieser Lösung sind relativ große Betätigungskräfte notwendig, um allein über die Aufschraubbewegung des ersten Kappenteils auf das Behältnis die axiale Aufstoßbewegung für die Membran des Halsteiles über die Dorneinheit des zweiten Kappenteiles vorzunehmen.The US 5,462,200 also shows a hermetically sealed container whose neck portion is closed at its free end face via a membrane. To open this membrane is an engaging mandrel, which has a fluid-permeable media channel and is part of a second cap part, which undergoes an axial feed movement to open the neck at the free end face with the membrane, provided that the first cap portion screwed the second cap portion across the container becomes. An arranged in the first cap member in the longitudinal axis of the container closure mandrel closes the media or fluid channel of the second cap portion and releases the latter as soon as the first cap portion is unscrewed from the container and thus removed. Also in this solution relatively large actuation forces are necessary to make the axial Aufstoßbewegung for the membrane of the neck portion on the mandrel unit of the second cap part alone on the Aufschraubbewegung of the first cap member on the container.

Ausgehend von diesem Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, diesen dahingehend weiter zu verbessern, dass zum einen die praktische Handhabung verbessert ist bei gleichzeitig erleichterter Herstellung.Based on this prior art, the invention is based on the object to further improve this to the effect that on the one hand the practical handling is improved while facilitating production.

Eine dahingehende Aufgabe löst ein Behältnis mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.This object is achieved by a container with the features of claim 1 in its entirety.

Erfindungsgemäß ist das jeweilige Mitnehmerelement am ersten Kappenteil als nasenartiger Vorsprung ausgebildet. Die jeweilige Ausnehmung im zweiten Kappenteil ebenso wie der jeweils zuordenbare nasenartige Vorsprung im Querschnitt des Behältnisses gesehen hat einen dreieckförmigen Verlauf. Für die drehende Mitnahmebewegung beim Aufschraubvorgang greifen die nasenartigen Vorsprünge an den Ausnehmungen an. In der entgegen gesetzten Abschraubbewegung löst sich das erste Kappenteil vom zweiten Kappenteil, indem hemmnisfrei die Mitnehmerelemente aus den zugeordneten Ausnehmungen herausgleiten.According to the invention, the respective driver element is formed on the first cap part as a nose-like projection. The respective recess in the second cap part as well as the respectively assignable nose-like projection seen in cross-section of the container has a triangular Course. For the rotating entrainment movement during Aufschraubvorgang the nose-like projections on the recesses. In the opposite unscrewing the first cap part of the second cap part dissolves by unhindered slide out the driver from the associated recesses.

Dadurch, dass mittels des Aufschraubvorganges des ersten Kappenteiles dieses das zweite Kappenteil derart mitnimmt, dass die Öffnungseinrichtung die Öffnung des Behältniskörpers veranlaßt, dass nach Abschrauben des ersten Kappenteils ein Verschlußteil desselben die Öffnung der Öffnungseinrichtung freigibt und, dass das zweite Kappenteil am Halsteil verbleibt, läßt sich das sogenannte Tropfteil, gebildet durch das zweite Kappenteil, formschlüssig mit dem Halsteil verbinden und an diesem festlegen, wobei das erste Kappenteil zur Freigabe der Öffnung am Behältniskörper von diesem entfernbar, insbesondere abschraubbar ist.Characterized in that by means of the Aufschraubvorganges the first cap part of the second cap member entrains such that the opening means causes the opening of the container body that after unscrewing the first cap part thereof a closure part of the opening of the opening device releases and that the second cap part remains on the neck part leaves the so-called drip part, formed by the second cap part, positively connect with the neck part and fix it to this, wherein the first cap part for releasing the opening on the container body of this removable, in particular unscrewable.

In Abhängigkeit des jeweiligen Anwendungsfalles und abhängig von Kundenwünschen lassen sich dergestalt zwei verschiedene Öffnungsvarianten mit nur einem Behältnis realisieren. So besteht zum einen die Möglichkeit das erfindungsgemäße Behältnis mit einer sogenannten offenen Kappenanordnung zu liefern, d.h. das erste Kappenteil ist erst teilweise, beispielsweise einen halben Gewindengang, auf dem zugeordneten Gewinde des Behältniskörpers aufgeschraubt, so dass der Anwender zunächst das erste Kappenteil weiter nach unten längs des Gewindes zu drehen hat, um dann den Behältniskörper mittels der Öffnungseinrichtung regelmäßig in Form eines Dornes zu öffnen. Hierbei verbleibt das zweite Kappenteil am Halsteil und die obere Kappe in Form des ersten Kappenteiles ist in die entgegengesetzte Richtung zur bisherigen Schraubrichtung zu drehen, um die Öffnung für eine Entnahme des bevorrateten Mediums aus dem Behältnis freizugeben. Zum andern kann das Behältnis bereits geöffnet ausgeliefert werden, d.h. das erste Kappenteil ist komplett aufgeschraubt; das zweite Kappenteil ist am Halsteil definiert festgelegt und die Öffnungseinrichtung (Dorn) hat bereits zur Freigabe der Öffnung des Behältniskörpers diesen durchstoßen. Der Anwender des Behältnisses muß nunmehr nur noch das obere erste Kappenteil abschrauben oder abdrehen, um den Behältnisinhalt beispielsweise in Form von bevorrateten Augentropfen nutzen zu können. Demgemäß ist mit nur einer Anordnung kundenspezifisch zwei verschiedene Arten an Entnahmemöglichkeiten realisierbar.Depending on the particular application and depending on customer requirements, two different opening variants can be realized in this way with only one container. Thus, on the one hand, it is possible to provide the container according to the invention with a so-called open cap arrangement, ie the first cap part is partially, for example half a thread, screwed onto the associated thread of the container body, so that the user first the first cap portion further down along has to turn the thread, then to open the container body by means of the opening means regularly in the form of a mandrel. Here, the second cap part remains on the neck portion and the upper cap in the form of the first cap member is to be rotated in the opposite direction to the previous screwing to release the opening for removal of the stored medium from the container. On the other hand, the container can already be delivered open, ie the first cap part is completely screwed; the second cap part is defined defined on the neck portion and the opening means (mandrel) has already pierced this to release the opening of the container body. The user of the container now only has to unscrew or turn off the upper first cap part in order to be able to use the contents of the container, for example in the form of stored eye drops. Accordingly, with only one arrangement custom two different types of removal options can be realized.

Aufgrund der jeweiligen plausiblen Betätigungsanordnung für beide Betätigungslösungen sind Fehlbedienungen weitgehend ausgeschlossen und auch wenn die erfindungsgemäße Behältnislösung gegebenenfalls gegenüber bekannten Lösungen über mehr Funktionsbauteile, insbesondere in Form zweier Kappenteile verfügt, wobei das zweite Kappenteil integraler Bestandteil des ersten Kappenteiles ist und von diesem in den Nichtfreigabestellungen für die Öffnung übergriffen ist, läßt sich insgesamt das erfindungsgemäße Behältnis einfach und kostengünstig herstellen, wobei der Behältniskörper insbesondere im Rahmen eines sogenannten Blasform-, Füll- und Verschließverfahrens, wie es unter der Marke "bottelpack®" in der Fachwelt bekannt geworden ist, hergestellt wird und die Kappenteile vorzugsweise im Spritzgußverfahren hergestellt sind.Due to the respective plausible actuating arrangement for both actuating solutions incorrect operation is largely excluded and even if the container solution according to the invention optionally over known solutions on more functional components, in particular in the form of two cap parts, wherein the second cap member is an integral part of the first cap part and of this in the non-release orders for the opening is overlapped, the container according to the invention can be a total and easy to produce, wherein the container body in particular in the context of a so-called blow molding, filling and sealing process, as it has become known under the brand "bottelpack ® " in the art, is produced and the cap parts are preferably made by injection molding.

Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Behältnisses ist dabei vorgesehen, dass Mitnehmerelemente des ersten Kappenteils, die am zweiten Kappenteil angreifen, die Mitnahmebewegung veranlassen und dass nach Eingriff des zweiten Kappenteils am Halsteil das Festlegeteil in der anderen Wirkrichtung verhakt ist und das erste Kappenteil bei dessen Abschraubvorgang freigibt. Hierdurch ist ein funktionssicherer Gebrauch sichergestellt und die axialen Verfahrstrecken der Kappenteile zueinander sind jedenfalls derart bemessen, dass eine sichere Verrastung des zweiten Kappenteils mit dem Behältniskörper erfolgt, so dass das erste Kappenteil hemmnisfrei die Behältnisöffnung freigeben kann. Vorzugsweise ist dabei ferner vorgesehen, dass zum Verhaken des zweiten Kappenteils am Halsteil des Behältniskörpers dieses einen um eine Stufe sich nach innen verjüngenden Eingriffsbereich aufweist, in den nach Überfahren der Stufe mindestens ein Eingriffsteil, vorzugsweise in Form eines Eingriffbügels, des zweiten Kappenteiles eingreift.In a particularly preferred embodiment of the container according to the invention it is provided that driver elements of the first cap part, which act on the second cap part, cause the entrainment movement and that after engagement of the second cap part on the neck part, the fixing part is hooked in the other direction of action and the first cap part in the Unscrewing releases. This is a reliable Ensured use and the axial Verfahrstrecken the cap parts to each other are in any case dimensioned such that a secure locking of the second cap member takes place with the container body, so that the first cap part can release the container opening without hindrance. Preferably, it is further provided that for hooking the second cap portion on the neck portion of the container body this has a step inwardly tapering engagement portion engages in the after passing the stage at least one engaging member, preferably in the form of an engagement bracket, the second cap member.

Bei einer weiteren besonders bevorzugten Ausführungsform des erfindungsgemäßen Behältnisses ist vorgesehen, dass das erste Kappenteil ein Festlegeteil aufweist, das in einer Wirkrichtung den Aufschraubvorgang des ersten Kappenteils ermöglicht und in einer anderen Wirkrichtung am Behältnis verbleibt und das erste Kappenteil für einen Abschraubvorgang freigibt, so dass dergestalt über das Festlegeteil eine weitere definierte Verbindung zu Teilen des Behältniskörpers geschaffen ist, was jedenfalls das Eindringen von Fremdmedien verhindern hilft. Es erlaubt das Festlegeteil einer Bedienperson insoweit einen funktionssicheren Gebrauch der Kappenteilanordnung.In a further particularly preferred embodiment of the container according to the invention, it is provided that the first cap part has a fixing part which allows the screwing-on of the first cap part in a direction of action and remains in a different direction of action on the container and releases the first cap part for a unscrewing operation, so that such on the fixing part a further defined connection to parts of the container body is created, which helps prevent the penetration of foreign media in any case. It allows the fixing part of an operator so far a functionally reliable use of the cap member assembly.

Vorzugsweise ist dabei vorgesehen, dass das Festlegeteil ein ringförmiger Festlegekörper ist, der nach innen vorstehende elastische Rastmittel aufweist, die in der einen Wirkrichtung korrespondierende Rastmittel am Behältnis überstreichen und in der anderen Wirkrichtung mit diesen verhaken. Dabei ist es vorzugsweise ferner vorgesehen, dass das erste Kappenteil an seiner freien, dem Behältniskörper zugewandten Seite das Festlegeteil aufweist und über eine leicht lösbare Trennstelle mit dem Festlegeteil verbunden ist. Auf diese Art und Weise verbleibt bei einem Freigabevorgang der Behältnisöffnung über das erste Kappenteil das ringförmige Festlegeteil am Behältniskörper und das erste Kappenteil ist mit geringen Betätigungskräften vom Festlegeteil trennbar.Preferably, it is provided that the fixing part is an annular fixing body, which has inwardly projecting resilient locking means which sweep in the one direction of action corresponding locking means on the container and hooked in the other direction of action with these. It is preferably further provided that the first cap portion has at its free, the container body side facing the fixing part and is connected via an easily detachable separation point with the fixing part. In this way, remains at a release process of Container opening on the first cap part, the annular fixing part on the container body and the first cap member is separable from the fixing part with low actuating forces.

Mit der erfindungsgemäßen Behältnislösung sind mit nur einer konstruktiven Ausgestaltung zwei Einsatzbereiche realisierbar, nämlich einmal eine Auslieferungsform, bei der die Öffnungseinrichtung des einen Kappenteils bereits die Öffnung des Behältniskörpers veranlaßt hat, oder als weitere Auslieferungsform vorzusehen, dass gerade die dahingehende Öffnung noch nicht vonstatten gegangen ist.With the container solution according to the invention two areas of use can be realized with only one structural design, namely once a delivery form in which the opening means of a cap portion has already caused the opening of the container body, or provide as a further delivery form, that just the pertinent opening has not yet gone by ,

Weitere vorteilhafte Ausführungsformen des erfindungsgemäßen Behältnisses sind Gegenstand der sonstigen Unteransprüche.Further advantageous embodiments of the container according to the invention are the subject of the other dependent claims.

Im folgenden wird das erfindungsgemäße Behältnis anhand eines Ausführungsbeispiels nach der Zeichnung näher erläutert. Dabei zeigen in prinzipieller und nicht maßstäblicher Darstellung die

Das in Fig.1 in seinem oberen Bereich dargestellte Behältnis soll insbesondere im Blasformverfahren hergestellt und in der Form gefüllt sowie verschlossen worden sein. Insbesondere ist das in der Art einer Ampulle ausgebildete Behältnis aus einem Kunststoffmaterial hergestellt, wobei die noch nachfolgend aufgezeigte Öffnungseinrichtung auch für anders hergestellte Behältnislösungen einsetzbar ist. An einen mit 10 bezeichneten Behältniskörper schließt sich nach oben hin ein Halsteil 12 an, auf das ein erstes Kappenteil 14 aufschraubbar ist. Das dahingehende Kappenteil 14 ist in einer perspektivischen Unteransicht in der Fig.4 wiedergegeben. In den Behältniskörper 10 ist ein nicht näher dargestelltes Fluid bevorratbar, beispielsweise in Form einer medizinisch wirkenden Flüssigkeit in Form von Augentropfen und dergleichen mehr. Anstelle von Flüssigkeiten lassen sich auch pastöse oder gasförmige Wirksubstanzen in den Behältniskörper einbringen, beispielsweise mit dem eingangs erwähnten Blasformverfahren, das in der Fachwelt unter der Markenbezeichnung "bottelpack®" bekannt geworden ist.This in Fig.1 The container shown in its upper region should in particular be produced in the blow molding process and filled and closed in the mold. In particular, the container formed in the manner of an ampoule is made of a plastic material, wherein the opening device shown below can also be used for differently prepared container solutions. At a designated 10 container body is followed at the top by a neck portion 12, to which a first cap member 14 is screwed. The pertinent cap member 14 is in a perspective bottom view in the Figure 4 played. In the container body 10, a fluid not shown in detail is stored, for example in the form of a medically acting liquid in the form of eye drops and the like. Also pasty or gaseous active substances in the container body can be introduced instead of liquids, for example, the aforementioned blow molding process, which has become known in professional circles under the brand name "bottelpack ®".

Neben dem ersten Kappenteil 14 ist ein zweites Kappenteil 16 vorhanden, das sich in axialer Längsrichtung 18 des Behältnisses zumindest teilweise zwischen dem ersten Kappenteil 14 und dem Halsteil 12 erstreckt. An seiner dem Halsteil 12 zugewandten Seite weist das zweite Kappenteil 16 eine Öffnungseinrichtung 20 auf, mit einer kanalartigen Öffnung 22, die in koaxialer Richtung zur Längsachse 18 das zweite Kappenteil 16 vollständig durchgreift und nach außen hin über eine trichterförmige Erweiterung 24 in die Umgebung mündet (vgl. Fig.3). Die dahingehende Öffnung 22 ist, wie dies die Darstellung nach der Fig.1 zeigt, von dem ersten Kappenteil 14 verschließbar, wobei ein konisch zulaufender Verschlußzapfen 26, der koaxial zur Längsachse 18 des Behältnisses angeordnet ist, in der Verschlußstellung nach der Fig.1 die kanalartige Öffnung 22 verschließt, indem der Verschlußzapfen 26 in die trichterförmige Erweiterung 24 des zweiten Kappenteils 16 eingreift. An ihrer, der Erweiterung 24 gegenüberliegenden Seite mündet die kanalartige Öffnung 22 in einen Umgebungsraum 28, der zum einen von der freien Stirnseite 30 des Halsteils 12 begrenzt ist sowie von der Innenmantelfläche des zweiten Kappenteils 16. Insoweit greift die Öffnungseinrichtung 20 mit einem konischen, dornartigen Fortsatz 32 in den Umgebungsraum 28 ein. Die freie Stirnseite 30 des Halsteils 12 ist Bestandteil einer zumindest teilweise konvex geformten Kalotte 34, die insoweit den Umgebungsraum 28 nach unten hin begrenzt, wobei die Kalotte 34 in Blickrichtung auf die Fig.1 gesehen nach unten sich konisch erweitert und in einen zylindrischen Übergriffsbereich 36 ausmündet, der sich um eine Stufe nach innen verjüngend in einen zylindrischen Eingriffsbereich 38 übergeht, der wiederum über ein konisch sich verbreiterndes Anschlußstück in Richtung einer Gewindestrecke 40 am Halsteil 12 ausmündet.In addition to the first cap part 14, a second cap part 16 is present, which extends in the axial longitudinal direction 18 of the container at least partially between the first cap part 14 and the neck part 12. On its side facing the neck part 12, the second cap part 16 has an opening device 20 with a channel-like opening 22, which fully engages through the second cap part 16 in a coaxial direction to the longitudinal axis 18 and opens out into the environment via a funnel-shaped extension 24 ( see. Figure 3 ). The pertinent opening 22 is, as the illustration of the Fig.1 shows, from the first cap part 14th closed, with a tapered locking pin 26 which is arranged coaxially to the longitudinal axis 18 of the container, in the closed position after the Fig.1 the channel-like opening 22 closes by the closure pin 26 engages in the funnel-shaped extension 24 of the second cap portion 16. At its opposite side of the extension 24, the channel-like opening 22 opens into an ambient space 28, which is bounded on the one hand by the free end face 30 of the neck portion 12 and the inner circumferential surface of the second cap portion 16. In this respect, the opening device 20 engages with a conical, thorn-like Extension 32 in the surrounding space 28 a. The free end face 30 of the neck portion 12 is part of an at least partially convex-shaped dome 34, which limits the extent of the surrounding space 28 down to the extent, the dome 34 in the direction of the Fig.1 seen downwardly conically widened and opens into a cylindrical overlap region 36, which merges by a step inwardly tapering in a cylindrical engagement portion 38, which in turn opens out via a conically widening fitting in the direction of a threaded section 40 on the neck portion 12.

In der Ausgangsstellung nach der Fig.1, die einem Auslieferungszustand der Behältnislösung entsprechen mag und die das Behältnis vor einer ersten Anwendung wiedergibt, greift entlang der Gewindestrecke 40 zumindest teilweise das erste Kappenteil 14 mit einem Innengewinde 42 an. Der dahingehende Gewindeeingriff ist derart, dass jedenfalls in der in der Fig.1 gezeigten Ausgangsstellung und bei der einen Art an aufgezeigten Ausführungsformen die Spitze des Fortsatzes 32 noch nicht in Eingriff ist mit der verschlossenen Stirnseite 30 des Halsteils 12. Der dahingehend stirnseitige Verschluß des Behälterhalses 12 kann durch das Kunststoffmaterial des Behältnisses selbst erzeugt sein oder in Form einer nicht näher erläuterten Verschlußmembran, die dahingehend die Stirnseite 30 des Behältnishalses 12 ausbildet.In the starting position after the Fig.1 , which may correspond to a delivery condition of the container solution and which reproduces the container before a first application, engages along the threaded section 40 at least partially the first cap member 14 with an internal thread 42 at. The pertinent threaded engagement is such that at least in the in the Fig.1 The starting point of the extension 32 is not yet engaged with the closed end face 30 of the neck portion 12. The frontal closure of the container neck 12 may be generated by the plastic material of the container itself or in the form of a non explained in more detail Closure membrane, which forms the end face 30 of the Behältnishalses 12.

An seinem gegenüberliegenden Ende mündet das erste Kappenteil 14, was insbesondere auch die Fig.4 zeigt, in ein ringartiges Festlegeteil 44 aus, das in einer Wirkrichtung 46 (siehe Pfeildarstellung in Fig.4) den Aufschraubvorgang des ersten Kappenteils 14 auf das Außengewinde des Halsteils 12 längs der Gewindestrecke 40 ermöglicht und in einer anderen, entgegengesetzten Wirkrichtung 48 (vgl. Pfeildarstellung in Fig.4) am Behältniskörper 10 rastend verbleibt, und das erste Kappenteil 14 läßt sich entlang einer linienförmig ausgebildeten Trennstelle 50 vom Festlegeteil 44 mit einer definierten Betätigungskraft lösen. Wie des weiteren die Fig.4 zeigt, besteht die Trennstelle 50 aus einer mäanderförmigen Linienstruktur, auf die die angrenzende Wandstärke zwischen Festlegeteil 44 und erstem Kappenteil 14 reduziert ist. Das Festlegeteil 44 ist mithin in der Art eines ringförmigen Festlegekörpers ausgebildet, der nach innen vorstehende, elastische Rastmittel 52 aufweist (vgl. Fig.4), die in der einen Wirkrichtung 46 korrespondierende Rastmittel 54 am Behältniskörper 10 (vgl. Fig.1) überstreichen und in der anderen Wirkrichtung 48 mit diesen verhaken. Hierfür bestehen die elastischen Rastmittel 52 aus zungenartigen und federnd nachgiebigen Blatteilen an der Innenumfangsseite des Festlegeteils 44 und die korrespondierenden Rastmittel 54 am Behältnis selbst sind aus stegartigen Flankenteilen gebildet, die am Halsteil 12 vorstehen im Übergangsbereich zur Oberseite des Behältniskörpers 10. Die dahingehenden korrespondierenden Rastmittel 54 können in geringerer Anzahl als die Rastmittel 52 vorhanden sein, beispielsweise in einer einzigen paarweise diametral einander gegenüberliegenden Anordnung, vergleichbar der Darstellung nach der Fig.1.At its opposite end, the first cap portion 14 opens, which in particular also the Figure 4 shows, in a ring-like fixing part 44, which in a direction of action 46 (see arrow illustration in Figure 4 ) allows the screwing operation of the first cap part 14 on the external thread of the neck portion 12 along the threaded section 40 and in another, opposite effective direction 48 (see arrow illustration in Figure 4 ) on the container body 10 detent remains, and the first cap member 14 can be solved along a line-shaped separation point 50 of the fixing member 44 with a defined actuation force. How the other Figure 4 shows, the separation point 50 consists of a meandering line structure to which the adjacent wall thickness between the fixing part 44 and the first cap member 14 is reduced. The fixing member 44 is thus formed in the manner of an annular fixing body having inwardly projecting, elastic locking means 52 (see. Figure 4 ), in the one direction of action 46 corresponding locking means 54 on the container body 10 (see. Fig.1 and cross over in the other direction of action 48 with these. For this purpose, there are the elastic locking means 52 of tongue-like and resilient sheet parts on the inner peripheral side of the fixing member 44 and the corresponding locking means 54 on the container itself are formed from web-like edge portions projecting on the neck portion 12 in the transition region to the top of the container body 10. The pertinent corresponding locking means 54th may be present in lesser number than the locking means 52, for example in a single pairwise diametrically opposed arrangement, comparable to the representation of the Fig.1 ,

Wird nun in der Wirkrichtung 46 und im Uhrzeigersinn das erste Kappenteil 14 aufgeschraubt, gerät dieses in eine Öffnungsstellung nach der Fig.2, wobei das erste Kappenteil 14 das zweite Kappenteil 16 derart mitnimmt, dass die freie Stirnseite 30 des Halsteils 12 von dem dornartigen Fortsatz 32 durchgriffen ist, so dass dergestalt der fluidführende Weg zwischen dem Inneren des Behältniskörpers 10 und dem noch aufgesetzten ersten Kappenteil 14 geschaffen ist. Bei der dahingehenden Aufschraubbewegung des ersten Kappenteils 14 ist der freie Weg der Gewindestrecke 40 verbraucht und das erste Kappenteil 14 auf dem Außengewinde des Halsteils 12 vollständig aufgeschraubt und das ringförmige Festlegeteil 44 ist gemäß der Darstellung nach der Fig.2 in vollumfänglichem Eingriff mit den korrespondierenden Rastteilen 54 am Halsteil 12.If the first cap part 14 is now screwed in the direction of action 46 and in the clockwise direction, it will move into an open position according to FIG Fig.2 , wherein the first cap member 14, the second cap member 16 entrains such that the free end face 30 of the neck portion 12 is penetrated by the mandrel-like extension 32, so that the fluid-carrying path between the interior of the container body 10 and the still mounted first cap member 14 is created , In the pertinent Aufschraubbewegung of the first cap member 14, the free path of the threaded section 40 is consumed and the first cap member 14 on the external thread of the neck portion 12 completely screwed and the annular fixing portion 44 is shown in the Fig.2 in full engagement with the corresponding locking parts 54 on the neck part 12th

Für die dahingehende Mitnahmebewegung weist das erste Kappenteil 14 mindestens ein Paar an diametral einander gegenüberliegenden Mitnehmerelementen 56 (vgl. Fig.2) auf, die an zugeordneten dreieckförmigen Ausnehmungen 58 am zweiten Kappenteil 16 angreifen und derart die Mitnahmebewegung veranlassen. Sowohl der nasenartige Vorsprung eines jeden Mitnehmerelementes 56 als auch der jeweils zuordenbare, im Querschnitt gesehen dreieckförmige Verlauf einer Ausnehmung 58 ist derart gewählt, dass eine drehende Mitnahmebewegung nach unten hin für einen Aufschraubvorgang möglich ist; dass aber in der entgegengesetzten Abschraubbewegung sich das erste Kappenteil 14 vom zweiten Kappenteil 16 lösen kann, indem hemmnisfrei die Mitnehmerelemente 56 aus den zugeordneten Ausnehmungen 58 herausgleiten können. Demgemäß fallen die Flankenwinkel in Aufschraubrichtung steiler aus als die benachbarten Flankenwinkel, die der Abschraubbewegung des ersten Kappenteils 14 zuordenbar sind.For the pertinent entraining movement, the first cap part 14 has at least one pair of diametrically opposed driver elements 56 (cf. Fig.2 ), which engage at associated triangular recesses 58 on the second cap portion 16 and thus cause the entrainment movement. Both the nose-like projection of each driver element 56 and the respectively assignable, seen in cross-section triangular course of a recess 58 is selected such that a rotating entrainment downwards for a screwing is possible; but that in the opposite unscrewing the first cap member 14 can be detached from the second cap member 16 by the cam members 56 can slide out of the associated recesses 58 without hindrance. Accordingly, the flank angles in the screwing-on direction are steeper than the adjacent flank angles which can be assigned to the unscrewing movement of the first cap part 14.

Wird nun das erste Kappenteil 14 in der anderen Wirkrichtung 48 und mithin entgegen dem Uhrzeigersinn über die Gewindestrecke 40 abgeschraubt, verhakt das Festlegeteil 44 am Behälterhals 12 und die dünnwandige Trennstelle 50 gibt nach mit der Folge, dass das erste Kappenteil 14 vollständig vom Behältnis trennbar ist, so dass sich eine Situation gemäß der Darstellung nach der Fig.3 ergibt, bei der das zweite Kappenteil 16 sowie das Festlegeteil 44 am Behältniskörper 10 verbleiben und das erste, nicht mehr näher dargestellte Kappenteil 14 eben entfernt ist. Um sicher zu stellen, dass das zweite Kappenteil 16 am Halsteil 12 verbleibt, wird bei der Aufschraubbewegung von der Fig.1 ausgehend nach Fig.2 mit an der Unterseite des zweiten Kappenteils 16 angebrachten Eingriffsbügeln 60 diese in Eingriff gebracht mit der im Durchmesser reduzierten Eingriffsstelle 38 am Halsteil 12. Aufgrund der bügelartigen Eingriffsausgestaltung erlaubt dies eine gewisse federelastische Nachgiebigkeit des zweiten Kappenteils 16 in seinem unteren Bereich, so dass bedingt durch die konische Verbreiterung des Halsteils 12 in diesem Bereich die Eingriffsbügel 60 den Übergriffsbereich 36 am Halsteil 12 überfahren können für einen nachträglich einrastenden Vorgang in den darunterliegenden Eingriffsbereich als Eingriffsstelle 38. Mit dem Abschrauben des ersten Kappenteils 14 wird dann auch die trichterförmige Erweiterung 24 freigegeben und das im Behältniskörper 10 bevorratete Medium steht für einen Entnahmevorgang zur Verfügung. Anschließend läßt sich durch entsprechendes Aufschrauben des ersten Kappenteils 14 wieder eine Situation nach der Fig.2 herstellen, bei der das Innere des Behältniskörpers 10 mediendicht verschlossen ist.Now, if the first cap member 14 is unscrewed in the other direction of action 48 and thus counterclockwise on the threaded section 40, the fixing part 44 hooked on the container neck 12 and the thin-walled separation point 50 yields, with the result that the first cap member 14 is completely separable from the container , so that a situation as shown by the Figure 3 results in the second cap member 16 and the fixing member 44 remain on the container body 10 and the first, not shown in more detail cap member 14 is just removed. To ensure that the second cap member 16 remains on the neck portion 12, is in the Aufschraubbewegung of the Fig.1 starting after Fig.2 with attached on the underside of the second cap member 16 engaging straps 60 this brought into engagement with the reduced diameter engagement point 38 on the neck portion 12. Due to the bow-shaped engagement design this allows a certain resilience of the second cap member 16 in its lower region, so that due to the conical broadening of the neck portion 12 in this area, the engaging bracket 60 can pass over the grip portion 36 on the neck portion 12 for a subsequent latching operation in the underlying engaging portion as the engagement point 38. With the unscrewing of the first cap member 14 and the funnel-shaped extension 24 is then released in the Container body 10 stored medium is available for a removal process. Subsequently, by appropriate screwing of the first cap part 14, a situation after the Fig.2 manufacture, in which the interior of the container body 10 is closed media-tight.

Gemäß den Darstellungen nach den Fig.5 und 6 ist dort jeweils in verschiedenen perspektivischen Ansichten das zweite Kappenteil 16 wiedergegeben. Bei der Darstellung nach der Fig.5 weist das Kappenteil 16 eine geschlossene Außenumfangsfläche auf und man erkennt an der Unterseite die einzelnen Eingriffsbügel 60. Bei der Ausgestaltung nach der Fig.6 ist der Außenmantel des zweiten Kappenteils 16 durchbrochen dargestellt mit einzelnen rechteckförmigen Ausnehmungen 62. Dies hat den Vorteil, dass die Eingriffselastizität für die Bügel 60 verbessert ist, so dass diese mit geringeren Betätigungskräften während des Aufschraubvorganges für das erste Kappenteil 14 in den Eingriffsbereich 38 gelangen können. Wie des weiteren in Blickrichtung auf die Fig.5 gesehen die rechte Darstellung zeigt, weist der Fortsatz 32 mehrere einzelne Durchgangsöffnungen 64 auf, die ein verbessertes Entnahmeverhalten sicherstellen. Vorzugsweise verfügt jedoch die dornartige Öffnungseinrichtung 20 über mehrere nicht mittig angeordnete Bohrungen, die den Durchgang zwischen Behältnis und Austrittsöffnung 22 freigeben. Vorzugsweise sind drei solcher Bohrungen oder Löcher am genannten Eingriffsdorn in exzentrischer Anordnung vorgesehen, um den Dorn in seinem Durchgriffsbereich zum Öffnen des Behältniskörpers 10 nicht zu schwächen. Insbesondere ist mit einer Vielzahl an Durchgangsöffnungen 64 ein sprayartiger Austrag möglich, sofern der Behältniskörper 10 derart elastisch nachgiebig ist, dass ein von Hand aufgebrachter Außendruck das bevorratete Medium an den Spraybereich in Form des zweiten Kappenteils 16 weitergibt. Um die verschiedenen Schraubvorgänge in den beiden Wirkrichtungen 46,48 von Hand einfacher veranlassen zu können und um insbesondere auch eine Trennung an der Trennstelle 50 mit geringen Betätigungskräften zu erreichen, weist der zylindrische Außenumfang des ersten Kappenteils 14 eine Handhabe in Form einer Riffelung 66 auf (vgl. Fig.4).According to the representations after the Fig.5 and 6 is there shown in different perspective views, the second cap member 16. In the presentation after the Figure 5 For example, the cap member 16 has a closed outer peripheral surface and can be seen on the underside the individual engagement bow 60. In the embodiment of the Figure 6 the outer jacket of the second cap member 16 is shown perforated with individual rectangular recesses 62. This has the advantage that the engagement elasticity for the bracket 60 is improved so that they can reach the engagement portion 38 with lower actuation forces during the Aufschraubvorganges for the first cap member 14 , As further in the direction of the Figure 5 As seen in the right-hand illustration, the extension 32 has a plurality of individual passage openings 64, which ensure improved removal behavior. Preferably, however, the spike-like opening device 20 has a plurality of holes not centrally arranged, which release the passage between the container and the outlet opening 22. Preferably, three such holes or holes are provided on said engaging mandrel in an eccentric arrangement, so as not to weaken the mandrel in its passage area for opening the container body 10. In particular, a spray-like discharge is possible with a plurality of passage openings 64, provided that the container body 10 is elastically yielding such that a manually applied external pressure passes the stored medium to the spray area in the form of the second cap portion 16. In order to be able to initiate the various screwdriving processes in the two directions of action 46,48 by hand more easily and in particular to achieve a separation at the separation point 50 with low actuating forces, the cylindrical outer periphery of the first cap portion 14 has a handle in the form of a corrugation 66 (FIG. see. Figure 4 ).

Bei einer Auslieferungsform nach der Fig.1 hat noch kein Eingriff in das Behältnisinnere stattgefunden. Es ist grundsätzlich auch denkbar, eine Auslieferungsform nach der Fig.2 zu wählen, bei der das zweite Kappenteil 16 bereits einen Öffnungsvorgang für das Behältnis bewirkt hat. Aufgrund der bereits erläuterten Gewindestrecke 40 sowie im Hinblick auf den Festlegebereich des Festlegeteils 44 an der Schulterübergangsstelle zwischen Halsteil 12 und Behältniskörper 10 ist dergestalt eine mediendichte Abtrennung gegenüber der Umgebung erreicht, so dass auch insoweit erhöhten Sterilitätsanforderungen Rechnung getragen wird.In a delivery form after the Fig.1 has not yet taken place in the container interior. It is basically also conceivable, a delivery form after the Fig.2 to choose in which the second cap member 16 has already caused an opening operation for the container. Due to the already explained threaded section 40 and in view of the fixing area of the fixing part 44 at the shoulder transition point between the neck portion 12 and container body 10 is thus achieved media-dense separation from the environment, so that in this respect increased sterility requirements are taken into account.

Claims (10)

  1. A container, in particular a plastic ampoule produced in a blow moulding process and filled and closed in the mould, with a neck part (12) adjoining a container body (10) onto which a first cap part (14) can be screwed and with a second cap part (16) that has at least one recess (58) and that extends at least partially between the first cap part (14) and the neck part (12) and that is provided with an opening device (20) having at least one opening (22) for opening the container body (10) and which can be sealed by means of the first cap part (14), by means of the process of screwing on the first cap part (14) the latter entraining the second cap part (16) such that the opening device (20) causes the container body (10) to open, after unscrewing the first cap part (14) a closure part (closure pin 26) of the latter freeing the opening (22) of the opening device (20), the second cap part (16) remaining on the neck part (14), entraining elements (56) of the first cap part (14), which act on the second cap part (16), enabling a rotating entraining movement for the screwing on process and bringing about the entraining movement, and after engagement of the second cap part (16) on the neck part (12), the first cap part (14) freeing the opening (22) when the latter is unscrewed, characterised in that the respective entraining element is formed on the first cap part (14) as a lug-type projection (56), that the respective recess (58) in the second cap part (16), like the respectively assignable lug-like projection (56), as viewed in the cross-section of the container, is triangular in shape, that for the rotating entraining movement during the screwing on process, the lug-type projections (56) engage in the recesses (58), and that in the opposite unscrewing movement the first cap part (14) becomes detached from the second cap part (16) by the entraining elements (56) sliding out of the assigned recesses (58) without any hindrance.
  2. The container according to Claim 1, characterised in that in order to interlock the second cap part (16) on the neck part (12) the latter has an engagement region (38) which tapers by one step to the inside, and which is engaged by at least one engagement part (60) of the second cap part (16) after crossing the step.
