Abstract

The invention relates to a container closure comprising a tubular-shaped sealing stopper which can be guided into a pouring passage of a container, said sealing stopper comprising at least one pair of axially distanced, annular shaped sealing projections which protrude in a radial manner towards the outside and which are arranged on the outer periphery thereof. The sealing projections are formed by the caps of a sawtooth-type profile on the external peripheral surface of the sealing stopper. Sections of the profile connecting adjacent caps together are inclined in an inward direction at an angle α in relation to a plane which is tangent to the caps. The angle opens out in the direction counter to the free end of the sealing stopper and has a ratio α : d which is between 1.0 and approximately 20, preferably approximately 1.0 and 8.0, at the most 2.0 and 5.5, whereby d = thickness measurement [mm] of the wall of the sealing stopper on the related cap.

Description

Behälterverschluss mit DichtstopfenContainer closure with sealing plug
Die Erfindung betrifft einen Behälterverschluss mit einem in eine Ausgießpassage eines Behälters einführbaren rohrförmigen Dichtstopfen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a container closure with a tubular sealing plug, which can be inserted into a pouring passage of a container, according to the preamble of claim 1.
Bekannt sind Behälterverschlüsse aus einem Kunststoffmaterial mit Dichtkonus, der im Zuge der Montage eines Verschlusses an einem Behälter in eine dichtend in eine Ausgießpassage des Behälters eingreifende Beziehung gebracht werden kann. Stopfen mit ringförmigen Dichtvorsprüngen aus einem Kunststoffmaterial sind ebenfalls bekannt (DE-U-7329838) und kommen beispielsweise zum Einsatz zum Verschließen von unter Druck stehenden Flaschen für Schaumweine zum Einsatz. Die Dichtvorsprünge sind entweder integral ausgeformt oder stellen separate, nachträglich angeordnete Teile dar.Container closures are known from a plastic material with a sealing cone, which can be brought into a sealing engagement in a pouring passage of the container in the course of the assembly of a closure on a container. Plugs with annular sealing projections made of a plastic material are also known (DE-U-7329838) and are used, for example, to close pressurized bottles for sparkling wines. The sealing projections are either integrally formed or represent separate, subsequently arranged parts.
Der Erfindung liegt die Aufgabe zugrunde, einen Behälterverschluss der gattungsgemäßen Art zu schaffen, bei dem der Dichtstopfen eine verbesserte Abdichtung bewirkt, ohne dass dadurch die Montage und Demontage des Behälterverschlusses sowie dessen Fertigung durch Spritzgießen gegenüber einem bekannten Behälterverschluss mit Dichtkonus wesentlich beeinträchtigt werden. Diese Aufgabe wird erfindungsgemäß durch die Merkmale gemäß dem kennzeichnenden Teil des Anspruches 1 gelöst. Ein Merkmal der Erfindung ist, dass die ringförmigen Dichtvorsprünge durch die Kuppen einer sagezahnartigen Profilierung des äußeren Umfangs des Dichtstopfens gebildet sind. Diese Profilierung lässt sich problemlos und in einem Arbeitsschritt beim Spritzgießen des Behälterverschlusses ausbilden. Ein weiteres Merkmal ist, dass die benachbarte Kuppen miteinander verbindenden Abschnitte der Profilierung unter einem bestimmten Winkel nach innen geneigt sind. Dabei steht der Winkel in einem bestimmten Verhältnisbereich umgekehrt proportional zur Dicke der Wandung des Dichtstopfens. Damit wird erreicht, dass sich der Behälterverschluss problemlos aus der Spritzgießform entformen lässt, da praktisch keine Hinterschneidungflächen vorliegen. Außerdem erhalten die Kuppen hierdurch eine auf die Formsteifigkeit des Dichtstopfens abgestimmte elastische Nachgiebigkeit, die eine ausreichende hohe Dichtwirkung gewährleistet. Gemäß einer bevorzugten Weiterbildung der Erfindung kann sich ferner die Wandung des Dichtstopfens vom freien Ende aus konisch erweitern, was das Einführen des Dichtstopfens in die Ausgießpassage des Behälters erleichtert.The invention has for its object to provide a container closure of the generic type, in which the sealing plug brings about an improved seal, without the assembly and disassembly of the container closure and its manufacture by injection molding being significantly impaired compared to a known container closure with a sealing cone. This object is achieved by the features according to the characterizing part of claim 1. A feature of the invention is that the annular sealing projections are formed by the tips of a sawtooth-like profile of the outer periphery of the sealing plug. This profile can be formed easily and in one step during the injection molding of the container closure. A further feature is that the adjacent sections of the profiling which connect one another are inclined inwards at a certain angle. The angle in a certain ratio range is inversely proportional to the thickness of the wall of the sealing plug. This ensures that the container closure can be easily removed from the injection mold, since there are practically no undercut surfaces. In addition, this gives the domes an elastic resilience which is matched to the dimensional stability of the sealing plug and which ensures a sufficiently high sealing effect. According to a preferred development of the invention, the wall of the sealing plug can also expand conically from the free end, which facilitates the insertion of the sealing plug into the pouring passage of the container.
Die Erfindung wird nachfolgend anhand der Zeichnung und einer Ausführungsform näher beschrieben. Es zeigen:The invention is described below with reference to the drawing and an embodiment. Show it:
Fig. 1 in geschnittener Ansicht einen erfindungsgemäß aufgebauten Behälterverschluss mit Dichtstopfen, undFig. 1 in a sectional view of a container closure constructed according to the invention with sealing plug, and
Fig. 2 in einer vergrößerten geschnittenen Ansicht ein Detail des Dichtstopfens.Fig. 2 shows an enlarged sectional view of a detail of the sealing plug.
Zum grundsätzlichen Aufbau eines Behälterverschlusses, an dem die Erfindung verwirklicht ist, wird auf Fig. 1 verwiesen. In Fig. 1 ist der Behälterverschluss als Schraubkappe ausgebildet und trägt das allgemeine Bezugszeichen 1. Der Behälterverschluss 1 umfasst in bekannter Weise eine End- oder Abschlusswand 2 und eine von deren äußeren Umfang abstehende rohrförmige Umfangswand 3. An der Innenseite der Umfangswand 3 ist ein ' Schraubgewinde 4 ausgebildet, das mit einem komplementären Schraubgewinde an einem Behälter (nicht gezeigt) zusammenwirken kann, um eine Ausgießpassage des Behälters zu verschließen. Anstelle einer Montage mittels eines Schraubgewindes kann, wenn erwünscht, auch eine Montage mittels in eine hintergreifende verriegelnde Beziehung miteinander tretenden Rastvorsprüngen am Behälterverschluss und Behälter vorgesehen sein. Diese Maßnahmen sind dem Fachmann bekannt und bedürfen daher keiner näheren Erläuterung.For the basic structure of a container closure on which the invention is implemented, reference is made to FIG. 1. In Fig. 1, the container closure is designed as a screw cap and bears the general reference number 1. The container closure 1 comprises, in a known manner, an end or end wall 2 and a tubular circumferential wall 3 projecting from its outer circumference Screw thread 4 formed, which can cooperate with a complementary screw thread on a container (not shown) to close a pouring passage of the container. Instead of assembly by means of a screw thread, assembly can also be provided, if desired, by means of latching projections on the container closure and container that enter into an interlocking interlocking relationship. These measures are known to the person skilled in the art and therefore do not require any further explanation.
Von der Innenseite der Endwand 2 ragt koaxial zur Umfangswand 3 ein kurzer rohrförmiger Dichtstopfen ab, der das allgemeine Bezugszeichen 5 trägt und im Detail in Fig. 2 gezeigt ist. Der Dichtstopfen 5 hat eine sich konisch von einer freien Endkante 12 aus in Richtung auf die Endwand 2 erweiternde Wandung 6. Die freie Endkante 12 kann, wie dargestellt, zum leichteren Einführen des Dichtstopfens 5 in eine Ausgießpassage gerundet sein.A short tubular sealing plug protrudes coaxially with the peripheral wall 3 from the inside of the end wall 2 and bears the general reference number 5 and is shown in detail in FIG. 2. The sealing plug 5 has a wall 6 which widens conically from a free end edge 12 in the direction of the end wall 2. The free end edge 12 can, as shown, be rounded for easier insertion of the sealing plug 5 into a pouring passage.
Während eine innere Umfangsfläche 7 der Wandung 6 vorzugsweise glatt ausgebildet ist, ist erfindungsgemäß die äußere Umfangsfläche sägezahnartig profiliert, wie dies in Fig. 2 mit dem allgemeinen Bezugszeichen 8 angedeutet ist. Die sägezahnartige Profilierung 8 bildet längs der axialen Länge der Wandung 6 mehrere axial voneinander beabstandete ringförmige Kuppen 9, 9', 9", die die Hochstellen der sagezahnartigen Profilierung 8 darstellen.While an inner peripheral surface 7 of the wall 6 is preferably smooth, according to the invention the outer peripheral surface is sawtooth-shaped, as indicated in FIG. 2 by the general reference number 8. The sawtooth-like profile 8 forms along the axial length of the wall 6 a plurality of axially spaced annular domes 9, 9 ', 9 ", which represent the high points of the sawtooth-like profile 8.
Die Abschnitte 10, 10' der sagezahnartigen Profilierung 8 zwischen benachbarten Kuppen 9, 9' bzw. 9', 9" sind unter einem Winkel a gegenüber einer Ebene 11 geneigt, die eine Tangente an benachbarte Kuppen 9, 9' bzw. 9', 9" bildet. Insbesondere sind die Abschnitte 10, 10' radial nach innen geneigt und öffnet sich der Winkel a in einer Richtung entgegengerichtet zur freien Endkante 12.The sections 10, 10 'of the sawtooth-like profile 8 between adjacent crests 9, 9' or 9 ', 9 "are inclined at an angle a with respect to a plane 11 which is tangent to adjacent crests 9, 9' or 9 ', 9 "forms. In particular, the sections 10, 10 ′ are inclined radially inward and the angle a opens in a direction opposite to the free end edge 12.
Bei der vorliegenden Ausführungsform der Erfindung sind drei Kuppen 9, 9', 9" vorgesehen, von denen benachbarte Kuppen 9, 9' bzw. 9', 9" durch jeweils einen geneigten Abschnitt 10, 10' axial voneinander beabstandet sind. Der Winkel α der Abschnitte 10, 10' kann gleich oder unterschiedlich sein. Es ' können, wenn erwünscht, auch mehr oder weniger als drei Kuppen vorgesehen sein.In the present embodiment of the invention, three crests 9, 9 ', 9 "are provided, of which adjacent crests 9, 9' and 9 ', 9" are each axially spaced apart by an inclined section 10, 10'. The angle α of the sections 10, 10 'can be the same or different. It If desired, more or less than three crests can also be provided.
Erfindungsgemäß steht ferner der Winkel in einem bestimmten Verhältnis zur Dicke d der Wandung 6 an der betreffenden Kuppe 9, von der die Neigung des Abschnittes 10 ihren Ausgang nimmt. Das Verhältnis sollte zwischen etwa 1 ,0 und etwa 20, vorzugsweise 1 ,0 und 8,0, höchst vorzugsweise 2,0 und 5,5, betragen. Dabei ist d in [mm] anzusetzen.According to the invention, the angle is furthermore in a specific relationship to the thickness d of the wall 6 on the respective crest 9, from which the inclination of the section 10 begins. The ratio should be between about 1.0 and about 20, preferably 1.0 and 8.0, most preferably 2.0 and 5.5. Here d is to be set in [mm].
Es wurde festgestellt, dass, wenn dieses Verhältnis eingehalten ist, die Formstabilität des Dichtstopfens 5 und die elastische Nachgiebigkeit der Kuppen 9 so aufeinander abgestimmt sind, dass gute Eigenschaften des Dichtstopfens 5 sowohl im Hinblick auf die Formung und Entformung der sagezahnartigen Profilierung 8 beim Spritzgießen des Behälterverschlusses als auch auf eine gewährleistete effiziente dichtende Eingriffnahme der Kuppen 9 mit einer Wand eines Behälters schaffen, wenn der Dichtstopfen 5 in dessen Ausgießpassage eingeführt wird. Dabei werden die radialen äußeren Abmessungen des Dichtstopfens 5 im Bereich der Kuppen 9 um ein geeignetes Maß, z.B. 0,15 mm, größer als diejenigen der Ausgießpassage gewählt.It has been found that, if this ratio is maintained, the dimensional stability of the sealing plug 5 and the elastic compliance of the tips 9 are coordinated with one another in such a way that good properties of the sealing plug 5 with regard to the shaping and demolding of the sawtooth-like profile 8 during injection molding of the Container closure as well as to ensure an efficient sealing engagement of the crests 9 with a wall of a container when the sealing plug 5 is inserted into its pouring passage. The radial outer dimensions of the sealing plug 5 in the area of the domes 9 are adjusted by a suitable amount, e.g. 0.15 mm, chosen larger than those of the pouring passage.
Obschon andere Kunststoffmaterialien für den Behälterverschluss verwendet werden können, wird bevorzugt ein Kunststoffmaterial aus der Gruppe der Polyolefine vorgesehen, z.B. Polyäthylen oder Polypropylen.Although other plastic materials can be used for the container closure, a plastic material from the group of the polyolefins is preferably provided, e.g. Polyethylene or polypropylene.
Es ist nicht erforderlich, dass die sägezahnartige Profilierung im Wesentlichen den gesamten äußeren Umfang des Dichtstopfens umfasst. Vielmehr könnte, wenn erwünscht, ein axialer Bereich des äußeren Umfangs glatt und ein anderer axialer Bereich mit der sagezahnartigen Profilierung versehen sein. It is not necessary that the sawtooth-like profiling essentially encompasses the entire outer circumference of the sealing plug. Rather, if desired, one axial area of the outer circumference could be smooth and another axial area could be provided with the sawtooth-like profile.
