Abstract

In a screw thread arrangement for the angular positioning, in the circumferential direction, of a first component having a multiple-thread pattern screw thread relative to a second component having a complementary multiple-thread screw thread pattern, in particular for a threaded closure cap relative to a container member, wherein a first angular spacing of adjacent runouts when viewed in a circumferential direction differs from angular spacing of adjacent runouts . As an alternative the dimensions of at least one thread turn of each multiple-thread screw thread pattern is different from those of a second thread turn. By such measures, when configurations of the components are rotationally asymmetrical, the two parts are always positively brought into alignment when the one component has been firmly screwed onto the other.

Description

Die Erfindung betrifft eine mehrgängige Schraubgewindeanordnung zur winkelmässigen Positionierung in Umfangsrichtung eines ersten, ein mehrgängiges Gewinde aufweisenden Bauteiles gegenüber einem zweiten, ein komplementäres mehrgängiges Gewinde aufweisenden Bauteil, insbesondere einer Schraubverschlusskappe gegenüber einem Behälterteil.The invention relates to a multi-thread screw arrangement for angular Positioning in the circumferential direction of a first, having a multi-start thread Component compared to a second, having a complementary multi-start thread Component, in particular a screw cap opposite a container part.

Eine gerttungsgemäße Schraubgewindeanordnung wird in FR-A-2542706 offenbart.A screw thread arrangement according to the device is disclosed in FR-A-2542706.

Aus verschiedenen Gründen ist es häufig, vor allem in der Verpackungsindustrie, erwünscht, einen Behälter zur Bevorratung von z.B. kosmetischen Produkten rotationsunsymmetrisch auszubilden, indem z.B. ein Abschnitt der Umfangswand des Behälters flach gestaltet wird, während der restliche Umfangsbereich kreisförmig oder oval oder in sonstiger Weise ausgestaltet sein kann. Wenn auf einen derartigen Behälter eine entsprechend rotationsunsymmetrisch gestaltete Verschlusskappe angeordnet werden soll, was zur Erzielung eines ästhetisch ansprechenden Erscheinungsbilds der Gesamtkombination aus Behälter und Kappe häufig gewünscht wird, muss gewährleistet sein, dass die Verschlusskappe in der Schliesstellung stets in einer bestimmten ausgerichteten Beziehung zum Behälter zu liegen kommt, anderenfalls sich in Bezug auf den Behälter Überhänge ergeben können, die nicht nur das äussere Erscheinungsbild der Kombination deutlich beeinträchtigen, sondern auch Schwierigkeiten beim Transport und der Lagerhaltung hervorrufen würden. Ausserdem könnte dadurch ein sich über beide Teile der Kombination erstreckender Werbehinweis unterbrochen werden. Bei Verschlusskappen, die durch axiales Aufprellen am Behälter befestigt werden, lässt sich eine erwünschte Ausrichtung vergleichsweise einfach durch Massnahmen an den beiden Teilen erreichen, die ein Aufprellen nur in einer bestimmten winkelmässigen Ausrichtung der Kappe zum Behälter ermöglichen. Eine derartige Lösung des Problems bietet sich bei Schraubverschlusskappen naturgemäss nicht an. Gegenüber dem Aufprellen hat andererseits das Schraubbefestigen einer Verschlusskappe am Behälter den Vorteil einer bedienungsfreundlicheren, kraftschonenden Handhabung.For various reasons, especially in the packaging industry, it is often desirable a container for storing e.g. cosmetic products rotationally asymmetrical train by e.g. a portion of the peripheral wall of the container is made flat, while the rest of the circumferential area is circular or oval or in some other way can be designed. If on such a container an accordingly rotationally asymmetrical designed closure cap should be arranged, which is to achieve an aesthetically pleasing appearance of the overall combination of container and Cap is often desired, it must be ensured that the cap in the Always be in a certain aligned relationship to the container in the closed position otherwise there may be overhangs in the container, which are not only significantly impair the external appearance of the combination, but also Would cause difficulties in transportation and storage. It could also thereby interrupting an advertising notice that extends over both parts of the combination become. For caps that are attached to the container by axial bouncing, a desired orientation is comparatively simple by taking measures on the two Achieve parts that bounce only in a certain angular orientation of the Allow the cap to the container. Such a solution to the problem offers itself Screw caps are naturally not on. On the other hand, compared to bouncing Screwing a cap on the container has the advantage of user-friendly, effortless handling.

Es besteht daher Bedarf nach einer rotationsunsymmetrischen Gestaltung einer Kombination aus einem ersten Bauteil, z.B. einer Schraubverschlusskappe, und einem zweiten Bauteil, z.B. einem Behälter, bei der der erste Bauteil in seiner Endaufschraubstellung stets in einer bestimmten Ausrichtung zum zweiten Bauteil zu liegen kommt, ohne dass es einer besonderen Sorgfalt bei der Handhabung des ersten Bauteils während des Aufschraubens bedarf.There is therefore a need for a rotationally asymmetrical design of a combination of a first component, e.g. a screw cap and a second component, e.g. one Container in which the first component in its final screw-on position is always in a certain position Alignment to the second component comes to lie without special care handling of the first component during screwing.

Erfindungsgemäss wird dies durch eine Schraubgewindeanordnung an einer derartigen Kombination gemäss dem Anspruch 1 ermöglicht. Wenn, ausgestattet mit einer derartigen Schraubgewindeanordnung, eine Schraubverschlusskappe auf einen Behälterteil aufgeschraubt werden soll, ist zuvor eine bestimmte winkelmässige Ausrichtung der beiden Teile zueinander erforderlich, damit die zusammenwirkenden Gewindegänge von Kappe und Behälterteil in Ausrichtung zueinander gelangen und ein Schraubeingriff zustande kommen kann. M.a.W.: die Kappe kann nicht in jeder beliebigen winkelmässigen Ausrichtung zum Behälterteil aufgeschraubt werden. Dazu bedarf es keiner sorgfältigen Handhabung seitens der Bedienungsperson, da die Ausrichtung sich selbständig bei einem anfänglichen tastenden Drehen der Verschlusskappe einstellt bzw. bemerkbar macht. Daher kann bei entsprechender Dimensionierung der Aufschraubstrecke erreicht werden, dass im vollständig aufgeschraubten Zustand die Verschlusskappe stets eine bestimmte Lagebeziehung zum Behälterteil einnimmt. Das äussere Erscheinungsbild einer Kombination aus Verschlusskappe und Behälter mit jeweils kongruenter rotationsunsymmetrischer Formgebung ist daher frei von Überständen und ermöglicht die Anbringung von Werbehinweisen auf z.B. flachen, beide Teile übergreifenden Umfangsbereichen. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen aufgeführt.According to the invention, this is achieved by a screw thread arrangement on such Combination according to claim 1 enables. If equipped with such a Screw thread arrangement, a screw cap screwed onto a container part is to be a certain angular alignment of the two parts to each other beforehand required so that the cooperating threads of the cap and the container part in Alignment to each other and a screw engagement can occur. M.a.W .: die Cap cannot be in any angular orientation to the container part be screwed on. This does not require careful handling on the part of Operator as the orientation is self-reliant on an initial groping Turning the cap adjusts or makes it noticeable. Therefore, with appropriate Dimensioning of the screw-on section can be achieved in that fully screwed on Condition the cap always assumes a certain positional relationship to the container part. The outer appearance of a combination of a cap and a container with each congruent rotationally asymmetrical design is therefore free of protrusions and enables the placement of advertising notices on e.g. flat, overlapping both parts Peripheral regions. Advantageous developments of the invention are in the subclaims listed.

    • Obschon die Erfindung nachfolgend in Verbindung mit der Anwendung bei Behältern, Flaschen und derartigen Gefässen zur Aufnahme flüssiger, pastöser oder rieseltähiger Produkte, z.B. Reinigungsmittel, kosmetische Mittel oder dgl. beschrieben wird, versteht es sich, dass sie auf dieses Anwendungsgebiet nicht beschränkt ist. Sie kann vielmehr immer dann vorteilhaft zur Anwendung kommen, wenn es gilt, zwei miteinander verschraubbare Bauteile in eine bestimmte winkelmässige Ausrichtung zueinander zu bringen, bevor der Schraubvorgang fortgesetzt werden kann. Die erfindungsgemässe mehrgängige Schraubgewindeanordnung lässt sich besonders vorteilhaft bei miteinander verschraubbaren Bauteilen aus einem Kunststoffmaterial im Zuge von deren Fertigung durch Spritzgiessen realisieren.Although the invention below in connection with the application to containers, bottles and such vessels for holding liquid, pasty or pourable products, e.g. Cleaning agents, cosmetic products or the like. Described, it is understood that they are based on this area of application is not restricted. Rather, it can always be advantageous When two parts that can be screwed together are used in a specific application bring angular alignment to each other before the screwing process continues can be. The multi-start screw thread arrangement according to the invention can be Particularly advantageous for components made of a plastic material that can be screwed together in the course of their manufacture by injection molding.

    Nachfolgend wird auf die Ausführungsform der Erfindung gemäss Fig. 1A-1C Bezug genommen. In Fig. 1A ist ein Behälterteil 1 gezeigt, der gemäss Fig. 1C eine rotationsunsymmetrische Ausbildung hat, indem er längs eines Umfangsbereiches kreisförmig und längs eines daran anschliessenden Umfangsbereiches rechteckförmig gestaltet ist. An einem axialen Ende des Behälterteiles 1 ist ein rohrförmiger I-Ials- oder Ansatzbereich 2 angeformt, der an seinem äusseren Umfang ein mehrgängiges Schraubgewinde trägt, das bei der vorliegenden Ausführungsform drei Gewindegänge, 3, 4 und 5 mit ähnlicher Steigung und Abmessung umfasst. In the following, reference is made to the embodiment of the invention according to FIGS. 1A-1C taken. In Fig. 1A, a container part 1 is shown, which according to Fig. 1C has rotationally asymmetrical formation by being circular along a circumferential region and has a rectangular shape along an adjoining circumferential region. On one Axial end of the container part 1 is a tubular I-Ials- or attachment area 2 is formed, has a multi-start screw thread on its outer circumference, which in the present case Embodiment three threads, 3, 4 and 5 with a similar pitch and dimension includes.

    Das mehrgängige Gewinde des Behälterteils 1 kann mit einem komplementären mehrgängigen Gewinde an einer Verschlusskappe 10, bestehend aus zu den Gewindegängen 3, 4 und 5 des Behälterteils 1 komplementären Gewindegängen 11, 12, 13, zusammenwirken, um die Schraubverschlusskappe 10 auf den Halsbereich 2 des Behälterteiles 1 aufschrauben zu können, bis eine untere freie Stimkante 14 der Verschlusskappe 10 in Anlage mit einer Schulterfläche 9 am Behälterteil 1 kommt, die längs des äusseren Umfanges des Halsbereiches 2 oder unmittelbar an diesem vorgesehen ist.The multi-start thread of the container part 1 can have a complementary multi-start Thread on a cap 10, consisting of the threads 3, 4 and 5 of the Container part 1 complementary threads 11, 12, 13, cooperate to To be able to screw the screw cap 10 onto the neck area 2 of the container part 1, to a lower free end edge 14 of the closure cap 10 in contact with a shoulder surface 9 on the container part 1 comes along the outer circumference of the neck area 2 or immediately is provided on this.

    In dieser Endstellung steht die Verschlusskappe 10 aufgrund der erfindungsgemässen Massnahmen in einer bestimmten winkelmässigen Ausrichtung zum Behälterteil 1. Die Schraubverschlusskappe 10 kann daher ähnlich wie der Behälterteil 1 eine rotationsunsymmetrische Konfiguration haben (nicht gezeigt), indem z.B. am äusseren Umfang der Schraubverschlusskappe 10 eine rechteckförmige Anformung ähnlich dem rechteckförmigen Umfangsbereich des Behälterteiles 1 vorgesehen sein kann, wobei erwünscht ist, dass die rechteckförmigen Bereiche des Behälterteiles 1 und der Schraubverschlusskappe 10 in deren Endstellung in Ausrichtung zueinander stehen.In this end position, the cap 10 is due to the inventive Measures in a certain angular orientation to the container part 1. Die Screw cap 10 can therefore similar to the container part 1 a have rotationally asymmetrical configuration (not shown), e.g. on the outer circumference the screw cap 10 a rectangular shape similar to the rectangular Circumferential region of the container part 1 can be provided, it being desirable that the rectangular areas of the container part 1 and the screw cap 10 in their End position in alignment with each other.

    Dies wird erfindungsgemäss dadurch erreicht, dass die Ausläufe 6, 7, 8 der Gewindegänge 3, 4, 5 des Behälterteils 1 und die Ausläufe (nicht bezeichnet) der komplementären Gewindegänge 11, 12, 13 (in Fig. 1B ist nur ein Auslauf zu erkennen) der Schraubverschlusskappe 10, die jeweils in einer gemeinsamen radialen Ebene liegen, nicht gleichmässig längs des Umfanges des Halsbereiches 2 bzw. der Schraubverschlusskappe 10 verteilt sind, sondern dergestalt, dass, in Umfangsrichtung betrachtet, die benachbarten Auslaufpaarungen 6, 7 in einem anderen Winkelabstand α1 als die Winkelabstände α2 und α3 der anderen benachbarten Auslaufpaarungen 7, 8 bzw. 8, 6 stehen. Bei der vorliegenden Ausführungsform beträgt α1 = 180°, während die Winkelabstände α2 und α3 jeweils 90° betragen.This is achieved according to the invention in that the outlets 6, 7, 8 of the threads 3, 4, 5 of the container part 1 and the outlets (not designated) of the complementary threads 11, 12, 13 (only one outlet can be seen in FIG. 1B) ) of the screw cap 10, which are each in a common radial plane, are not evenly distributed along the circumference of the neck region 2 or the screw cap 10, but in such a way that, viewed in the circumferential direction, the adjacent outlet pairs 6, 7 at a different angular distance α 1 as the angular distances α 2 and α 3 of the other adjacent outlet pairs 7, 8 and 8, 6, respectively. In the present embodiment, α 1 = 180 °, while the angular distances α 2 and α 3 are each 90 °.

    In entsprechender Weise sind die Ausläufe der Gewindegänge 11-13 an der Schraubverschlusskappe 10 gestaltet. Diese kann daher nur auf den Halsbereich 2 des Behälterteils 1 aufgeschraubt werden, wenn zuvor eine winkelmässige Ausrichtung der Ausläufe der zusammenwirkenden Gewindegänge 3, 4, 5 bzw. 10, 11, 13 vorgenommen wurde. Bei einer entsprechend bemessenen axialen Schraublänge des mehrgängiges Gewindes des Halsbereichs 2 bis zum Erreichen der Endstellung der Schraubverschlusskappe 10 wird die gewünschte Ausrichtung der beiden Teile automatisch bewirkt.In a corresponding manner, the outlets of the threads 11-13 are on the Screw cap 10 designed. This can therefore only on the neck area 2 of the Container part 1 are screwed on if an angular alignment of the The cooperating threads 3, 4, 5 and 10, 11, 13 were run out. With an appropriately dimensioned axial screw length of the multi-thread of the Neck area 2 until the end position of the screw cap 10 is reached desired alignment of the two parts is automatically effected.

    Bei der vorbeschriebenen Ausführungsform der Erfindung sind drei Gewindegänge jeweils am Behälterhalsbereich 2 bzw. an der Schraubverschlusskappe 10 vorgesehen, wobei es nicht erforderlich ist, dass sämtliche Gewindegänge tragend sind. Anstelle eines drei- oder mehrgängigen Gewindes könnte auch ein zweigängiges Gewinde vorgesehen werden, bei dem die Gewindeausläufe in keinem symmetrischen Winkelabstand zueinander stehen. So könnte z.B. der Winkelabstand bei Betrachtung in einer Umfangsrichtung 270° und in einer entgegengesetzten Umfangsrichtung 90° betragen.In the embodiment of the invention described above, three threads are each on Container neck area 2 or provided on the screw cap 10, but not it is necessary that all threads are load-bearing. Instead of a three or multi-start thread could also be provided a two-start thread in which the thread runs are not at a symmetrical angular distance from each other. So could e.g. the angular distance when viewed in a circumferential direction 270 ° and in one opposite circumferential direction 90 °.

    Die zweite Ausführungsform der Erfindung wird nachfolgend anhand von Fig. 2A-2C erläutert. In Fig. 2A-2C tragen gleiche oder ähnliche Bauteile wie bei der ersten, in Verbindung mit Fig. 1A-1C erläuterten Ausführungsform die gleichen Bezugszeichen. Es kann daher auf eine erneute Beschreibung dieser Teile verzichtet werden. Bei der zweiten Ausführungsform der Erfindung sind am Halsbereich 2 des Behälterteils 1 und an der Verschlusskappe 10 jeweils ein zweigängiges Gewinde vorgesehen. Die Gewindegänge am Halsbereich 2 tragen die Bezugszeichen 15, 16 und die an der Verschlusskappe 10 die Bezugszeichen 17, 18. Die Ausläufe 6, 7 der Gewindegänge 15, 16 des Behälterhalsbereichs 2 - und ebenso die des komplementären Gewindes der Verschlusskappe 10 - sind symmetrisch angeordnet, wie dies in Fig. 2C gezeigt ist, indem die Gewindeausläufe 6, 7 in einem Winkelabstand α1 = α2 = 180° stehen.The second embodiment of the invention is explained below with reference to FIGS. 2A-2C. 2A-2C, the same or similar components as in the first embodiment explained in connection with FIGS. 1A-1C bear the same reference numerals. It is therefore not necessary to describe these parts again. In the second embodiment of the invention, a two-start thread is provided on the neck area 2 of the container part 1 and on the closure cap 10. The threads on the neck area 2 have the reference symbols 15, 16 and those on the closure cap 10 have the reference symbols 17, 18. The outlets 6, 7 of the threads 15, 16 of the container neck region 2 - and also those of the complementary thread of the closure cap 10 - are arranged symmetrically , as shown in FIG. 2C, in that the thread outlets 6, 7 are at an angular distance α 1 = α 2 = 180 °.

    Die Vorgabe einer bestimmten winkelmässigen Ausrichtung der Verschlusskappe 10 in Bezug auf den Behälterhalsbereich 2, damit ein Aufschrauben der Verschlusskappe 10 vorgenommen werden kann, wird dadurch erzielt, dass die Gewindegänge 15, 16 des Halsbereiches 2 bzw. 17, 18 der Schraubverschlusskappe 10 bei übereinstimmender Steigung unterschiedliche Breitenabmessungen A, A' bzw. B, B' haben. So könnte z.B. das Verhältnis B:A bzw. B':A' 3:2 betragen. Dadurch können nur Gewindegänge 15, 18 bzw. 16, 17 am Behälterhalsbereich 2 und an der Schraubverschlusskappe 10 mit zueinander passender Breitenabmessung in Eingriff miteinander gebracht werden, was eine bestimmte winkelmässige Ausrichtung der Schraubverschlusskappe 10 zum Behälterhalsbereich 2 voraussetzt, so dass ähnliche Wirkungen wie bei der ersten Ausführungsform erzielt werden.The specification of a specific angular orientation of the closure cap 10 in relation on the container neck area 2 so that the screw cap 10 is screwed on can be achieved in that the threads 15, 16 of the neck area 2 or 17, 18 of the screw cap 10 different with a matching slope Have width dimensions A, A 'or B, B'. For example, the ratio B: A or B ': A' 3: 2 be. As a result, only threads 15, 18 or 16, 17 on the container neck area 2 and on the screw cap 10 with a matching width dimension in engagement brought together, which is a certain angular orientation of the Screw cap 10 to the container neck area 2, so that similar effects as in the first embodiment.

    Wenn erwünscht, könnte auch eine Schraubgewindeanordnung am Behälterhalsbereich und der Schraubverschlusskappe vorgesehen werden, die eine Kombination der Ausgestaltungen gemäss der ersten und zweiten Ausführungsform der Erfindung darstellt.If desired, a screw thread arrangement on the container neck area and the Screw cap are provided, which according to a combination of the configurations of the first and second embodiments of the invention.
