Description

Die Erfindung betrifft einen luftdichten Gefäßverschluß mit einer auf den Rand der zu verschließenden Öffnung auflegbaren, den Rand überragenden Abdeckscheibe, die einen von einer aus gummielastischem Material bestehenden, auf den Öffnungsrand auflegbaren Membrane ausgefachten Ririgkörper aufweist, der zwei einander umfassende Ringe besitzt, zwischen denen der Rand der Membrane eingespannt ist.The invention relates to an airtight vessel closure with a cover plate which can be placed on the edge of the opening to be closed and which projects beyond the edge and which has a rigid body which is made up of a membrane made of rubber-elastic material and can be placed on the opening edge and which has two mutually encompassing rings, between which the Edge of the membrane is clamped.

Eine Anordnung dieser Art ist aus der CH-A 23 525 bekannt. Bei dieser bekannten Anordnung soll die Membrane ausschließlich kraftschlüssig zwischen den beiden Ringen des Ringkörpers gehalten werden. Die beiden, die Membrane zwischen sich einklemmenden Ringe besitzen nämlich glatte, einander zugewandte Ringflächen. Die Erfahrung hat jedoch gezeigt, daß mit Hilfe derartiger Ringe die Membrane nicht nur nicht sicher genug gehalten wird, sondern auch bei vernünftigem Herstellungs- und Montageaufwand nicht zuverlässig genug in eine definierte Stellung zwischen den beiden Ringen gebracht werden kann. Vielmehr besteht hierbei die Gefahr, daß sich der zwischen den Ringen eingeklemmte bzw. einzuklemmende Rand der Membrane bereits während der Montage der Ringe oder jedenfalls im Laufe längerer Betriebszeiten verschiebt, was zur Folge hat, daß eine definierte Stellung des Rands der Membrane nur sehr schwierig zu erreichen ist und die Membrane im Laufe längerer Betriebszeiten auf jeden Fall aus der durch die beiden Ringe gebildeten Halterung herausschlüpft.An arrangement of this type is known from CH-A 23 525. In this known arrangement, the membrane should only be held non-positively between the two rings of the ring body. The two rings that clamp the membrane between themselves have smooth, mutually facing ring surfaces. Experience has shown, however, that with the aid of such rings the membrane is not only not held securely enough, but cannot be reliably brought into a defined position between the two rings even with reasonable manufacturing and assembly work. Rather, there is a risk that the edge of the membrane clamped or clamped between the rings will shift during the assembly of the rings or in any case during longer operating times, with the result that a defined position of the edge of the membrane is very difficult to achieve is reached and the membrane slips out of the holder formed by the two rings in the course of longer operating times.

Die US-A 3 901 405 zeigt ebenfalls einen Gefäßverschluß mit zwei eine Membrane zwischen sich aufnehmenden Ringen. Hierbei handelt es sich jedoch um zwei aufeinander aufliegende Ringe, die sich nicht umfassen und die Membrane dementsprechend auch nicht zwischen siqh einspannen können, so daß hier eine Klebverbindung zur Halterung der Membrane unbedingt erforderlich ist. Dies erforder jedoch einen hohen Aufwand und ergibt dennoch keinen zuverlässigen, dauerhaften Halt der Membrane.US-A-3 901 405 also shows a vessel closure with two rings holding a membrane between them. However, these are two rings lying on top of each other, which do not encompass each other and accordingly cannot clamp the membrane between siqh, so that an adhesive connection for holding the membrane is absolutely necessary here. However, this requires a lot of effort and still does not result in a reliable, permanent hold of the membrane.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Anordnung gattungsgemäßer Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß bereits bei vergleichsweise geringen Klemmkräften ein zuverlässiger, dauerhafter Halt der Membrane gewährleistet ist.Proceeding from this, it is therefore the object of the present invention to improve an arrangement of the generic type with simple and inexpensive means such that a reliable, permanent hold of the membrane is ensured even with comparatively low clamping forces.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die die Membrane zwischen sich einklemmenden Ringe formschlüssig aneinander festgelegt sind, wobei der radial innere Ring zumindest einen radial nach außen gerichteten, vom äußeren Ring hintergriffenen Wandvorsprung aufweist.This object is achieved in that the membranes are clamped to one another in a form-fitting manner, the radially inner ring having at least one radially outwardly directed wall projection which is engaged by the outer ring.

Der erfindungsgemäß vorgesehene Formschluß der beiden Ringe ergibt in vorteilhafter Weise auch einen formschlüssigen Sitz des zwischen den Ringen eingespannten Rands der Membrane. Hierdurch ist in vorteilhafter Weise sichergestellt, daß bereits mit vergleichsweise geringen Klemmkräften ein ausgezeichneter Halt der Membrane gewährleistet wird. Aus diesem Grund können daher bei der Herstellung der Ringe in vorteilhafter Weise verhältnismäßig große Toleranzen zugelassen werden, was die Herstellung nicht unwesentlich vereinfacht und verbilligt. Ein weiterer ganz besonderer Vorteil der erfindungsgemäßen Maßnahmen ist jedoch darin zu sehen, daß der hier vorgeshene Formschluß auch die exakte Montage der Membrane erleichtert. In diesem Zusammenhang ist nämlich davon auszugehen, daß die Membrane durch die zur Erzielung des Formschlusses vorgesehenen Kanten auch bereits beim Zusammenführen der Ringe zuverlässig gehalten bzw. mitgenommen wird, so daß ohne nennenswerten Aufwand ein zuverlässiger gegenseitiger Eingriff erreicht wird. Die erfindungsgemäßen Maßnahmen ergeben demnach sowohl eine einfache und kostengünstige Herstellung als auch eine einfache und kostengünstige Montage und führen dennoch zu einem zuverlässigen Halt der Membrane, was sich positiv auf die Gestehungskosten und die Qualität des Endprodukts auswirkt. Da es sich beim Endprodukt im vorliegenden Fall um einen Massenartikel handelt, ergeben diese Verbesserungen hinsichtlich Preis und Qualität insgesamt einen sehr großen wirtschaftlichen Wert.The positive engagement of the two rings provided according to the invention advantageously also results in a positive fit of the edge of the membrane clamped between the rings. This advantageously ensures that excellent retention of the membrane is ensured even with comparatively low clamping forces. For this reason, relatively large tolerances can therefore advantageously be permitted in the manufacture of the rings, which considerably simplifies and reduces the cost of manufacture. Another very special advantage of the measures according to the invention, however, can be seen in the fact that the positive connection provided here also facilitates the exact assembly of the membrane. In this context, it can be assumed that the membrane is held or carried reliably even when the rings are brought together by the edges provided to achieve the positive connection, so that a reliable mutual engagement is achieved without any significant effort. The measures according to the invention accordingly result in both simple and inexpensive manufacture and simple and inexpensive assembly and nevertheless lead to a reliable hold of the membrane, which has a positive effect on the production costs and the quality of the end product. Since the end product in the present case is a mass-produced item, these improvements in terms of price and quality result in very great economic value overall.

Vorteilhafte Ausgestaltungen und zweckmäßige Weiterbildungen der übergeordneten Maßnahmen sind in den Ansprüchen 2 bis 5 gekennzeichnet.Advantageous refinements and expedient further developments of the superordinate measures are characterized in claims 2 to 5.

Nachstehend wird ein in der Zeichnung schematisch dargestelltes Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Die Zeichnung ziegt einen Radialschnitt durch einen erfindungsgemäßen Gefäßverschluß.An exemplary embodiment of the invention shown schematically in the drawing is explained in more detail below with reference to the drawing. The drawing shows a radial section through a vascular occlusion according to the invention.

Der in der Zeichnung dargestellte Gefäßverschluß besteht aus einem Ringkörper 1, der durch eine Membrane 2 ausgefacht ist. Der Ringkörper 1 ist zweiteilig und besteht aus einem inneren Stützring 3 und einem diesen unter gegenseitigem Formschluß umfassenden Spannring 4. Die Membrane 2 wird hierbei durch einen Ausschnitt aus einer Warenbahn gebildet und ist mit ihrem Rand 5 zwischen dem Stützring 3 und dem Spannring 4 eingeklemmt.The vessel closure shown in the drawing consists of an annular body 1, which is fanned out by a membrane 2. The ring body 1 is in two parts and consists of an inner support ring 3 and a clamping ring 4 encompassing this with mutual positive locking. The membrane 2 is here formed by a cutout from a material web and is clamped with its edge 5 between the support ring 3 and the clamping ring 4.

Der Stützring 3 ist hier im Bereich seiner von der Membrane 2 ausgefachten Stirnseite mit einer nach radial außen gerichteten Randabkröpfung 6 versehen, die vom Rand 5 der Membrane 2 umfaßt und von dem den Rand 5 der-Membrane 2 anpressenden Spannring 4 hintergriffen wird. Durch den hierdurch bewirkten Formschluß werden die Klemmverbindung zur Halterung der Membrane 2 entlastet und die Membrane 2 in ihrer Lage gesichert, so daß auch bei robusten Betriebsverhältnissen ein dauerhafter Halt der Membrane 2 zu erwarten ist. Im dargestellten Ausführungsbeispiel ist der Stützring 1 mit einer weiteren, hier im Bereich seiner, der Membrane 2 gegenüberliegenden Stirnseite angeordneten, radial nach außen gerichteten Randabkröpfung 6 versehen, was eine zuverlässige Lagesicherung des hier als einfacher Ring mit kreisförmigem Querschitt ausgebildeten Spannrings 4 ergibt.The support ring 3 is provided here in the region of its end face, which is folded out by the membrane 2, with a radially outwardly directed edge offset 6, which is encompassed by the edge 5 of the membrane 2 and is engaged behind by the clamping ring 4 pressing against the edge 5 of the membrane 2. Due to the resulting positive connection, the clamp connection for holding the membrane 2 is relieved and the membrane 2 is secured in its position, so that a permanent hold of the membrane 2 is to be expected even under robust operating conditions. In the exemplary embodiment shown, the support ring 1 is provided with a further radially outward bent portion 6, which is arranged here in the region of its end face opposite the membrane 2, which provides a reliable securing of the position of the clamping ring 4 formed here as a simple ring with a circular cross section.

Der Stützring 3 und der Spannring 4 können einfach als Kunststoff-Spritzgußformlinge ausgebildet sein. Der Stützring 3 bildet dabei ein formstabiles Bauteil. Der Spannring 4 kann als federnder Ring ausgebildet sein.The support ring 3 and the clamping ring 4 can simply be designed as plastic injection moldings. The support ring 3 forms a dimensionally stable component. The clamping ring 4 can be designed as a resilient ring.

Der dargestellte Gefäßverschluß wird einfach mit der Membrane 2 auf den Rand des durch seine Umrißlinien angedeuteten Gefäßes 7 aufgelegt. Anschließend wird die Membrane 2 einfach im Bereich ihres den Gefäßrand überspannenden Bereichs leicht zum Gefäßinnenraum hin durchgedrückt, wie bei 2a angedeutet ist. Hierbei wird eine der Wölbung der Membrane 2 entsprechende Luftmenge aus dem Behälterinhalt verdrängt. Beim Zurückfedern der gummielastischen Membrane 2 entsteht im Gefäß 7 ein Unterdruck, welcher den Gefäbßverschluß auf dem Gefäßrand festsaugt. Das infolge der Luftverdrängung erzeugte Teilvakuum stellt außerdem sicher, daß der Behälterinhalt über lange Zeiträume hinweg frisch bliebt und ausgezeichnet konserviert ist.The vessel closure shown is simply placed with the membrane 2 on the edge of the vessel 7 indicated by its outline. Subsequently, the membrane 2 is simply pushed slightly towards the interior of the vessel in the area of its area spanning the edge of the vessel, as indicated at 2a. Here, an amount of air corresponding to the curvature of the membrane 2 is displaced from the container contents. When the rubber-elastic membrane 2 springs back, a negative pressure is created in the vessel 7, which pulls the vascular closure firmly onto the edge of the vessel. The partial vacuum created as a result of air displacement also ensures that the contents of the container remain fresh for long periods and are excellently preserved.

Die Membrane 2 besteht aus einem geruchfreien, synthetischen Gummi. Dieses Material gewährleistet eine ausgezeichnete Elastizität, so daß eine selbstättige Rückfederung der Membrane 2 erfolgt und gleichzeitig auch eine satte Anlage am Rand des zu verschließenden Gefäßes gewährleitet ist, auch wenn dieser Rand leichte Unebenheiten aufweisen sollte, was z. B. bei mittels eines Dosenöffners geöffneten Büchsen vorkommen kann. Außerdem ist hierbei eine völlige Porenfreiheit sichergestellt, so daß das im zu verschließenden Behälter erzeugte Teilvakuum auch über einen langen Zeitraum hinweg unverändert aufrecht erhalten wird. Ferner ist sichergestellt, daß eine derartige Membrane weder den Geruch des Behälterinhalts annimmt, noch ihren Eigengeruch an diesen abgibt. Im dargestellten Ausführungsbeispiel soll die Membrane 2 aus durchsichtigem Material bestehen, so daß sich praktisch ein Sichtfenster ergibt und eine Kontrolle des Behälterinhalts möglich ist.The membrane 2 consists of an odor-free, synthetic rubber. This material ensures excellent elasticity, so that a self-resilient resilience of the membrane 2 takes place and at the same time a full contact is ensured at the edge of the vessel to be closed, even if this edge should have slight unevenness, which, for. B. can occur with open cans by means of a can opener. In addition, complete freedom from pores is ensured, so that the partial vacuum generated in the container to be closed is maintained unchanged even over a long period of time. It is also ensured that such a membrane does not accept the smell of the container contents, nor does it give off its own odor to the latter. In the illustrated embodiment, the membrane 2 is made of transparent material, so that there is practically a viewing window and a control of the container content is possible.

Im dargestellten Ausführungsbeispiel ist die Membrane 2 nur in der dargestellten Montagestellung zwischen dem Stützring 3 und dem Spannring 4 eingespannt. Es wäre aber auch denkbar, die Membrane 2 mit dem Spannring 4 durch geeignete Mittel fest zu verbinden.In the illustrated embodiment, the membrane 2 is clamped between the support ring 3 and the clamping ring 4 only in the assembly position shown. But it would also be conceivable to firmly connect the membrane 2 to the clamping ring 4 by suitable means.
