Abstract

The invention proposes a container, for use in particular for food, consisting of two separate halves between which sealing is improved by virtue of the fact that the flexible flange (19) on the sealing ring (3) which is integrally moulded with the lid, for instance, has a projection which improves the sealing action in a simple way.

Description

Die Erfindung bezieht sich auf ein Behältnis für Speisen, insbesondere zum Servieren, Aufbewahren, und Transportieren von Speisen oder ähnlichem gemäß dem Oberbegriff des Patentanspruchs 1, und insbesondere auf einen für die Abdichtung des Behältnisses geeigneten Dichtungskörper gemäß dem Oberbegriff des Patentanspruchs 11.The invention relates to a container for Food, especially for serving, storage, and transporting food or the like in accordance with the preamble of claim 1, and in particular on a suitable one for sealing the container Sealing body according to the preamble of Claim 11.

Solche Behältnisse werden regelmäßig dann eingesetzt, wenn es darum geht, Speisen, insbesondere warme Speisen, in einer Großküche zusammenzustellen und dann durch ein geeignetes Logistiksystem an Endverbraucher, wie zum Beispiel Krankenhäuser oder dergleichen zu liefern. Ein Behältnis der eingangs beschriebenen Art ist beispielsweise in den älteren Patentanmeldungen P4325205, P4410943, P4410945, 19506394, P19526719 bzw. 19528771 des Anmelders beschrieben. Der Offenbarungsgehalt dieser älteren Patentanmeldungen soll in diese vorliegende Patentanmeldung mit einbezogen werden.Such containers become regular then used when it comes to food, in particular hot dishes to be put together in a commercial kitchen and then through a suitable logistics system to end users, such as hospitals or deliver the like. A container of the beginning described type is for example in the older patent applications P4325205, P4410943, P4410945, 19506394, P19526719 and 19528771 of the applicant described. The revelation content of these older ones Patent applications are said to be present in this patent application be included.

Bei solchen Behältnissen kommt es darauf an, daß beide Schalen, d. h. Boden- bzw. Deckelteil mit guter Abdichtung der darin vorgesehenen Vertiefungen miteinander verbunden werden können. Um eine gute Abdichtung zu erhalten, wurde bislang an einen zumindest eine Vertiefung beispielsweise des Bodenteils umlaufender Dichtungskörper gedacht, der mindestens einen elastischen Dichtungsschenkel aufweist, über den die Abdichtung mit dem Deckelteil erzielt wurde. Als Dichtfläche dient hierbei eine Seitenfläche des Dichtungsschenkels. Anhand dieser planflächigen Anlage des Dichtungsschenkels an die Wandung der vertiefung wurde versucht, die Abdichtung zu erreichen. Es zeigte sich jedoch bei Versuchen, daß derartige Abdichtmaßnahmen lediglich eingeschränkt aufrechterhalten werden können.With such containers, it is important that both shells, d. H. Bottom or lid part with good Sealing the depressions provided therein can be connected to each other. To be a good one To date, at least one has received sealing a depression surrounding the bottom part, for example Seal body thought of at least one has elastic sealing leg over which sealing with the cover part was achieved. As A sealing surface serves a side surface of the sealing leg. Based on this flat system of the sealing leg to the wall of the recess an attempt was made to achieve the seal. It showed however, in attempts that such Only keep sealing measures to a limited extent can be.

Aufgabe der vorliegenden Erfindung ist es somit, ein Behältnis der eingangs beschriebenen Art derart weiterzubilden, daß die Abdichtmaßnamen verbessert werden. Eine weitere Aufgabe der Erfindung besteht darin, einen Dichtungskörper zu schaffen, der ebenfalls verbesserte Abdichtmaßnahmen ermöglicht.The object of the present invention is therefore a container of the type described above to further develop that the sealing measures improved become. Another object of the invention is in creating a sealing body that also enables improved sealing measures.

Diese Aufgabe wird hinsichtlich des Behältnisses mit den Merkmalen des Anspruchs 1 und hinsichtlich des Dichtungskörpers mit den Merkmalen des Anspruchs 11 gelöst.This task is regarding the container with the features of claim 1 and with regard of the sealing body with the features of the claim 11 solved.

Erfindungsgemäß wird der zum Abdichten eines Boden- bzw. Deckelteils des Behältnisses herangezogene Dichtungsschenkel des Dichtungskörpers mit einem vorsprung versehen, der zum Abdichten des Boden- bzw.-Deckelteils gegen die Wandung der Vertiefung gedrückt wird. Mit dieser Maßnahme, den Dichtungsschenkel mit einem beispielsweise nasenartigen Vorsprung zu versehen, ist es möglich, die Berührungsfläche bzw. Auflagefläche zwischen Dichtungsschenkel und Wandung der Vertiefung gezielt zu bestimmen bzw. einzustellen, so daß die durch den elastischen Dichtungsschenkel hervorgetutene Druckbeaufschlagung optimiert gegebenenfalls auch erhöht werden kann. Auch wird mit dieser Maßnahme erreicht, daß die hohen Anforderungen an die Herstellung bzw. Handhabung der bei der Planflächenanlage sich berührenden Oberflächen reduziert werden, ohne daß dabei die Dichteigenschaften beeinflußt werden. Zusätzlich wird erfindungsgemäß durch die Ausbildung des Dichtungsschenkels mit einem Vorsprung erreicht, daß sich über die geometrische Gestaltung bzw. Dimensionierung (Höhe, Breite, Form) bei vorgegebener Elastizität des Dichtungsschenkels die Druckbeaufschlagung auf die Wandung der Vertiefung einstellen läßt. Bei vorgegebener Elastizität kann über den Vorsprung auch die beispielsweise durch die Wandung der Vertiefung hervorgerufene Auslenkung des Dichtungsschenkels eingestellt bzw. optimiert werden. Die vorgegebene Elastizität des Dichtungsschenkels ist darüber hinaus geeignet, eventuell auftretende Toleranzen des abzudichtenden Boden- oder Deckelteils auszugleichen.According to the invention for sealing a Bottom or lid part of the container used Sealing leg of the sealing body with provided with a projection which is used to seal the floor or cover part against the wall of the recess is pressed. With this measure, the sealing leg with a nose-like, for example To provide protrusion, it is possible to touch the surface or contact surface between the sealing leg to determine and wall of the recess specifically or adjust so that through the elastic sealing leg excelled pressurization optimized, if necessary, can also be increased. This measure also ensures that the high Manufacturing and handling requirements the surfaces in contact with the flat surface system can be reduced without losing the sealing properties to be influenced. In addition, the invention through the formation of the sealing leg achieved with a head start that over the geometric design or dimensioning (Height, width, shape) given the elasticity of the Sealing leg the pressurization on the The wall of the recess can be adjusted. With given Elasticity can also be achieved, for example, via the projection caused by the wall of the depression Deflection of the sealing leg set or be optimized. The given elasticity the sealing leg is also suitable any tolerances of the seal to be sealed Compensate base or lid part.

Erfindungsgemäß ist es von Vorteil, wenn die Wandung der Vertiefung eine Auflagefläche aufweist, die in Gegenüberlage des Vorsprungs vertikal angeordnet ist, und darüberhinaus als Dichtfläche dient. Zusätzlich ist es von Vorteil, wenn die Wandung oberhalb der Auflagefläche eine schräg verlaufende Einlauffläche aufweist, um den Dichtungsschenkel durch eine elastischen Biegeumformung auszulenken. Durch diese besondere Gestaltung der Wandung wird erreicht, daß der Dichtungsschenkel mit Vorsprung eine Kraft in horizontaler Richtung auf die Wandung ausübt. Dadurch wird verhindert, daß durch die Biegeelastizität des Dichtungsschenkels eine Kraft in vertikaler Richtung ausgeübt wird, wenn beispielsweise die Auflagefläche ebenfalls schräg verlaufen würde, wodurch die vertikale Kraftkomponete ein Öffnen des Behältnisses hervorrufen würde. Wird die Auflagefläche der Wandung gegenüber dem nicht ausgelenktem Dichtungsschenkel versetzt angeordnet, vorzugsweise um 1,4 und 1,9 mm, wird je nach Elastizität des Dichtungsschenkels und Länge des Dichtungsschenkels erreicht, daß beim Zusammenführen bzw. Schließen des Behältnisses der Dichtungsschenkel auf die schräg verlaufende Einlauffläche aufsetzt und um den Versatz zwischen vertikaler Auflagefläche für den Vorsprung des Dichtungsschenkels und des nicht ausgelenkten Dichtungsschenkels ausgelenkt wird. Die Einlauffläche und die Auflagefläche bilden eine Kantenlinie, über die der ausgelenkte Dichtungsschenkel samt Vorsprung geführt wird. Wird darauf geachtet, daß lediglich der Vorsprung des Dichtungsschenkels mit der Wandung in Anlagekontakt tritt und somit von der schräg laufenden Einlauffläche über die Kantenlinie auf die Auflagefläche unter elastischer Biegeverformung des Dichtungsschenkels geführt wird, wird erreicht, daß eine Art Schnappeffekt bereitgestellt wird. Denn nach dem Aufsetzen des Dichtungsschenkels auf die Einlauffläche wird der Dichtungsschenkel gestaucht, wobei die elastische Biegeverformung des Dichungsschenkels bis zum Überstreichen der Kantenlinie zunimmt. Nach Überstreichen der Kantenlinie entfäält die die Stauchung hervorgerufene Einlauffläche und der Dichtungsschenkel kann sich nach unten, in Richtung der Auflagefläche entspannen. Dadurch wird ein Schnappeffekt erzeugt, der den Dichtungsschenkel samt vorsprung in die optimale vorgegebene Position bringen kann. Durch die vertikale Auflagefläche wird somit erreicht, daß eine verminderte horizontale Kraft erzeugt wird, die ein Auseinandertreiben der beiden Teile des Behältnisses bewirken kann.According to the invention, it is advantageous if the wall the recess has a bearing surface which in Is arranged vertically opposite the projection, and also serves as a sealing surface. In addition is it is advantageous if the wall above the contact surface has an inclined inlet surface, around the sealing leg by an elastic Deflect bending. Through this special Design of the wall ensures that the Sealing leg with protrusion a force in the horizontal Direction on the wall. This will prevents from the bending elasticity of the sealing leg exerted a force in the vertical direction if, for example, the contact surface also would run obliquely, causing the vertical Power components cause the container to open would. The bearing surface is opposite the wall offset the undeflected sealing leg arranged, preferably around 1.4 and 1.9 mm, depending on the elasticity of the sealing leg and Length of the sealing leg reaches that when merging or closing the container of Sealing leg on the sloping inlet surface touches down and the offset between vertical Support surface for the projection of the sealing leg and the undeflected sealing leg is deflected. The inlet surface and the contact surface form an edge line over which the deflected Sealing leg including projection is guided. Becomes made sure that only the projection of the sealing leg comes into contact with the wall and thus from the inclined running surface the edge line on the support surface under elastic Bending deformation of the sealing leg is performed, it is achieved that a kind of snap effect is provided becomes. Because after putting on the sealing leg the sealing leg is on the inlet surface compressed, the elastic bending deformation of the Sealing leg until the edge line is swept over increases. After sweeping over the edge line the inflow surface caused by the compression and the seal leg can slide down, in Relax in the direction of the contact surface. This will a snap effect that creates the sealing leg including the projection into the optimal predetermined position can bring. Due to the vertical contact surface achieved a reduced horizontal force which is a drifting apart of the two parts of the container can cause.

Die eben aufgeführten Vorteile treffen auch auf den mit Anspruch 11 definierten Dichtungskörper zu.The advantages just mentioned also apply the sealing body defined in claim 11.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the subclaims.

Weist die Einlauffläche femer zumindest abschnittsweise eine Rillenstruktur auf, so wird auf einfache Weise ein Maßnahme bereitgestellt, mit der ein sich beim lufdichten Verschließen des Behältnisses eventuell aufbauender Überdruck kontrolliert und gegebenenfalls vermieden wird. Dadurch wird erreicht, daß beim Schließen die Dichtungslippe vorerst auf die mit der Rillenstruktur versehenen Einlauffläche auftritt. In diesem Zustand wird das Behältnis nicht vollständig abgedichtet. Werden die beiden Einzelteile des Behältnisses weiter um eine vorgegebene Wegstrecke aufeinanderzubewegt, so wird die Dichtungslippe entlang der Einlauffläche weitergeführt, wobei der durch das Zusammenführen auftretende Druck über die von der Dichtungslippe nicht vollständig abgedichteten Rillenstruktur aus dem Innenraum des Behältnisses entweichen kann. Sind die beiden Einzelteile des Behältnisses derart aufeinanderzubewegt, daß der eventuell an dem Behältnis vorhandene Verschließmechanismus betätigt werden kann, wechselt die Dichtungslippe von der Einlauffläche auf die Dichtfläche über. Durch diese Maßnahme wird erreicht, daß lediglich ein in der letzten Phase des Schließens des Behältnisses ein Überdruck erzeugt wird. Allerdings kann dieser minimale Überdruck von jedermann und ohne besonderen technischen Aufwand sowie ohne besondere Kraftanstrengung überwunden werden. Dadurch daß die Einlauffläche mit einer Rillenstruktur versehen ist, muß die Dichtungslippe keiner weiteren besonderen Ausgestaltung unterworfen werden, da die Rillen einen genügend großen Durchlaß für den Überdruck zur Verfügung stellen.Also has the inlet surface at least in sections a grooved structure on it is easy Way provided a measure by which one is when sealing the container airtight building overpressure checked and if necessary is avoided. This ensures that the First close the sealing lip on the one with the groove structure provided inlet surface occurs. In this Condition, the container is not completely sealed. The two individual parts of the container will continue to move a predetermined distance towards each other, so is the sealing lip along the inlet surface continued, the by merging pressure occurring above that of the sealing lip not fully sealed groove structure can escape the interior of the container. If the two individual parts of the container are moved towards one another in such a way that maybe on the container existing locking mechanism can be operated the sealing lip changes from the inlet surface over the sealing surface. This measure will achieved that only one in the last phase of Closing the container creates an overpressure becomes. However, this minimal excess pressure can be used by anyone and without special technical effort as well as overcome without special effort become. Characterized in that the inlet surface with a groove structure is provided, the sealing lip does not have to subject to further special design, because the grooves have a sufficiently large passage for provide the excess pressure.

Wird z. B. gemäß Anspruch 3 der vorsprung am Ende des Dichtungsschenkels vorgesehen, so wird auch einem mit geringer Elastizität ausgestatteter Dichtungsschenkel aufgrund der Hebelwirkung eine große Druckbeaufschlagung auf die Wandung der Vertiefung bereitgestellt.Is z. B. according to claim 3 of the projection provided at the end of the sealing leg, so also a sealing leg with low elasticity a big one due to the leverage Pressurizing the wall of the recess provided.

Wird darüberhinaus der Vorsprung vorteilhafterweise spitz nach außen zulaufend bzw. sich verjüngend ausgebildet, so wird der Druck, der durch den Dichtungsschenkel samt Vorsprung auf die Wandung einwirkt, durch das Spitzzulaufen bzw. Verjüngen auf eine Linie übertragen, und somit ebenfalls optimiert.In addition, the projection is advantageous tapering to the outside or tapering trained, so the pressure caused by the Sealing leg including projection on the wall acts by tapering or rejuvenating one Transfer line, and thus also optimized.

Es hat sich gezeigt, daß gemäß Anspruchs 5 es von besonderem Vorteil ist, wenn die Spitze des Vorsprungs einen Öffnungswinkel von 90° aufweist und eine Seitenfläche des spitz zulaufenden Vorsprungs mit dem Dichtungsschenkel einen Winkel von 150° bildet. Mit dieser Ausgestaltung wird gewährleistet, daß die Spitze bzw. der Endpunkt des Vorsprungs beim Verschließen des Deckelteils mit dem Bodenteil nicht einstülpt bzw. verbogen wird, wodurch sonst die Dichteigenschaften an sich beeinträchtigt wären. Ferner ist festzustellen, daß diese spezielle Spitzengestaltung des Vorsprungs auch für die Praxis die besten Dichteigenschaften aufzeigt und somit für die tägliche Handhabung sich als am geeignetsten erwies.It has been shown that according to claim 5 is particularly beneficial if the tip of the projection has an opening angle of 90 ° and Side surface of the tapered projection with the sealing leg forms an angle of 150 °. This configuration ensures that the Tip or the end point of the projection when closing of the cover part with the bottom part does not turn over or bent, which otherwise the sealing properties would be affected. Furthermore is notice that this special top design the best sealing properties for practical use shows and thus for daily handling turned out to be the most suitable.

Wird hingegen gemäß Anspruch 6 der Vorsprung im Kontaktbereich mit der Wandung der Vertiefung abgerundet ausgebildet, so wird mit dieser geometrischen Gestaltung erreicht, daß einerseits bei besonders starker Beanspruchung dennoch eine auf eine Minimal fläche reduzierte und damit erhöhte Druckbeaufschlagung gewährleistet wird, und andererseits kann über die Dimensionierung der Rundung, d.h. durch geeignete Wahl des Radius, ebenfalls die Druckbeaufschlagung beeinflußt werden.However, according to claim 6, the lead in the contact area with the wall of the recess rounded, with this geometric Design achieves that on the one hand at particular heavy use but one to a minimum reduced area and thus increased pressure is guaranteed, and on the other hand can about the dimensioning of the rounding, i.e. by suitable Choice of the radius, also the pressurization to be influenced.

Die Dichteigenschaften des Behältnisses können auch in vorteilhafter Weise gemäß Anspruch 7 erhöht bzw. beeinflußt werden, indem für den Vorsprung in der Wandung der Vertiefung eine dem Vorsprung im geschlossenen Zustand des Behältnisses gegenüberliegende Nut vorgesehen ist. So kann beispielsweise über die Tiefe der Nut oder aber auch durch eine sonstige geometrische Ausgestaltung der Nut der Dichtungsbereich bestimmt und gegebenenfalls auf die anfallenden Anforderungen speziell ausgerichtet werden.The sealing properties of the container can also increased in an advantageous manner according to claim 7 or be influenced by for the lead in the wall of the recess one the projection in opposite state of the closed container Groove is provided. For example over the depth of the groove or through another Geometric design of the groove of the sealing area determined and if necessary on the accruing Requirements can be specifically tailored.

Darüberhinaus kann es gemäß Anspruch 8 von Vorteil sein, mindestens zwei Vorsprünge an einem Dichtungsschenkel vorzusehen, um beispielsweise die Abdichtung zu erhöhen oder aber je nach geometrischer Ausgestaltung der Wandung der Vertiefung Rechnung zu tragen, um die Abdichtung optimal zu gestalten.Furthermore, according to claim 8 be advantageous, at least two protrusions on one To provide sealing leg, for example, the To increase sealing or depending on the geometric Design of the wall of the recess bill to wear to optimally design the seal.

Auf die Vorteile der Merkmale des Anspruchs 9 wird insbesondere auf die Patentanmeldung 19506394 verwiesen, deren Gegenstand sich insbesondere mit einem angeformten Dichtungskörper an einem Deckelteil befaßt und hiermit vollinhaltlich in den Offenbarungsgehalt dieser Patentanmeldung aufgenommen wird.On the advantages of the features of the claim 9 will focus in particular on the patent application 19506394 referenced, whose subject is particularly with a molded sealing body on one Covered part and hereby fully in the Disclosure content of this patent application added becomes.

Darüberhinaus ist es vorteilhaft, wenn sich der Dichtungsschenkel nicht innenseitig an die Wandungen der Vertiefungen anlegt, sondern gemäß Anspruch 10 jede Vetiefung eine stegartige Einfassung aufweist und der Dichtungsschenkel von außen an die Einfassung gedrückt wird. In diesem Fall weist die von der Vertiefung abgewandten Außenoberfläche der Wandung die schräg verlaufende Einlauffläche und die vertikal verlaufende Auflagefläche auf. Durch diese besondere Anordnung wird erreicht, daß, insbesondere wenn ein Unterdruck in den Vertiefungen erzeugt wird, eine sichere Abdichtung gewährleistet wird. zusätzlich wird dann durch den Unterdruck und der Biegeelastizität des Dichtungsschenkels der Dichtungsschenkel gegen die Außenseite der stegartigen Einfassung gedrückt. Auch hier wird durch die von der Einlauffläche und der vertikal angeordneten Auflagefläche erzeugten Kantenlinie und dem damit einhergehenden Schnappverschluß die Schließfunktion unterstützt.In addition, it is advantageous if the Sealing leg not on the inside of the walls of the wells, but according to claim 10 each recess has a web-like border and the sealing leg from the outside to the border is pressed. In this case it points from the recess facing away from the outer surface of the wall sloping inlet surface and the vertical one Contact surface. Because of this special arrangement is achieved that, especially when a negative pressure is generated in the wells, a safe one Sealing is guaranteed. in addition then due to the vacuum and the elasticity of the sealing leg the sealing leg against the outside the web-like edging pressed. Also here is by the of the inlet surface and the vertical arranged contact surface generated edge line and the associated snap lock the Locking function supported.

Die für die Ansprüche 2 bis 10 beschriebenen Vorteile gelten auch für den mit Anspruch 11 definierten Dichtungskörper an sich, so daß von einer Wiederholung der Argumente abgesehen wird.Those described for claims 2 to 10 Advantages also apply to the one defined in claim 11 Seal body itself, so that from repetition the arguments are ignored.

In Fig. 1 ist zur Erläuterung als Beispiel ein aus der Patentanmeldung P4410943 oder 19506394 des Anmelders zur Erläuterung entnommenes Behältnis 1 gezeigt. Das Behältnis 1 weist ein Deckelteil 1A und ein mit identischen schalenförmigen Konturen ausgebildetes Bodenteil 1 B auf, wobei in diesem Beispiel an das Deckelteil 1A ein Dichtungskörper 3 dauerhaft angebracht, vorzugsweise angeformt ist. Das in Fig. 1 dargestellte Behältnis weist drei als Aufbewahrungsabschnitte der Speisen fungierende Vertiefungen 5A, 5b und 5c auf. Im seitlichen Mittelbereich 7 des Deckelteils 1 A sind vorzugsweise auf einer Seite eine Lasche 9 beispielsweise in Form eines Materialscharniers und ein Loch 11 ausgebildet, die zum Öffnen des Behältnisses verwendet werden. Die Lasche 9 ist von dem Einfassungsrand 13 des Deckelteils 1A nach außen weg gerichtet.In Fig. 1 is an example for explanation patent application P4410943 or 19506394 des Container removed by the applicant for explanation 1 shown. The container 1 has a cover part 1A and formed with identical bowl-shaped contours Bottom part 1 B, in this example to the Cover part 1A a sealing body 3 permanently attached, is preferably molded. The one shown in Fig. 1 Container has three as storage sections recesses 5A, 5b functioning as food and 5c. In the lateral central area 7 of the cover part 1A are preferably a tab 9 on one side, for example in the form of a material hinge and a Hole 11 formed to open the container be used. The tab 9 is from the border edge 13 of the cover part 1A directed outwards.

In Fig. 2, die das Deckelteil gemäß Fig. 1 von unten zeigt, ist deutlich zu sehen, daß gegenüberliegend zum Zwickelbereich 7 am Einfassungsrand 13 ein Verriegelungsabschnitt 15 ausgebildet ist. Wie in der Schnittansicht entlang des Schnitts III-III in Fig. 2 deutlicher in Fig. 3 zu sehen ist, weist der Verriegelungsabschnitt 15 einen Haken 17 als Hintergriff auf, in den der Einfassungsrand 13 des deckungsgleichen Bodenteils 1B, eingehängt werden kann. Der in diesem Beispiel dargestellte angeformte Dichtungskörper 3 weist - wie Fig. 3 zeigt - an das Deckelteil 1 A einen innenliegenden Dichtungsschenkel 19 auf. Der innenliegende Dichtungsschenkel 19 des Dichtungskörpers 3 ist aus einem anderen Material, insbesondere weicherem oder elastischerem Material gebildet als das Deckelteil 1 A an sich.In Fig. 2, the cover part of FIG. 1 of shows below, it is clearly seen that opposite to the gusset area 7 at the border 13 Locking section 15 is formed. Like in the Sectional view along the section III-III in Fig. 2 more clearly can be seen in Fig. 3, the locking portion 15 a hook 17 as a rear grip, in which the Border edge 13 of the congruent bottom part 1B, can be attached. The one in this example molded sealing body 3 shown has - how Fig. 3 shows - on the cover part 1 A an inner Sealing leg 19 on. The inner sealing leg 19 of the sealing body 3 is made of one other material, especially softer or more elastic Material formed as the cover part 1 A per se.

An dem innenliegenden Dichtungsschenkel 19 ist der nasenartige Vorsprung 21 vorgesehen, der hier spitz zulaufend dargestellt ist. Wird nun das Behältnis geschlossen, d. h. der Einfassungsrand 13 des Bodenteils 1B wird von dem Haken 17 des Deckelteils 1A hintergriffen, so wird der elastische Dichtungsschenkel 19 entsprechend der Schräge der Wandung der Vertiefung des Bodenteils 1B ausgelenkt. Dadurch wird aufgrund der Elastizität des Dichtungsschenkels 19 eine Rückstellkraft erzeugt, die den Vorsprung 21 auf die Wandung der Vertiefung 5A des Bodenteils drückt. Auf diese Weise wird das Behältnis abgedichtet.On the inner sealing leg 19 the nose-like projection 21 is provided here is shown tapered. Now the container closed, d. H. the border edge 13 of the bottom part 1B is engaged by the hook 17 of the cover part 1A, the elastic sealing leg 19 according to the slope of the wall of the recess of the bottom part 1B deflected. This is due to the elasticity of the sealing leg 19 a restoring force generates the projection 21 on the wall of the depression 5A of the bottom part. To this The container is sealed in this way.

Es hat sich als besonders vorteilhaft herausgestellt, daß wenn der innenliegende Dichtungsschenkel folgende aufeinander abgestimmte, hier beispielhaft wiedergegebene Maßangaben enthält. So ist es von Vorteil, wenn die Spitze des Vorsprungs einen Winkel von 90° aufweist und die Seitenfläche des Dichtungsschenkels 19 mit der Seitenfläche des Vorsprungs 21 einen Winkel von 150° bildet.It turned out to be particularly advantageous that if the inner seal leg following coordinated, exemplary here reproduced dimensions contains. That's the way it is beneficial if the tip of the projection is at an angle of 90 ° and the side surface of the sealing leg 19 with the side surface of the projection 21 forms an angle of 150 °.

Ferner hat es sich als vorteilhaft erwiesen, wenn die Seitenfläche des Dichtungsschenkels 19 um ein bestimmtes Maß M versetzt angeordnet ist. Es hat sich ferner als besonders vorteilhaft herausgestellt. wenn beispielsweise der Dichtungsschenkel eine Höhe von 5,69 mm bzgl. der Stegoberfläche 29 aufweist, die Spitze um 5,5 mm von der Stegoberfläche 29 beabstandet wird, die Stirnfläche 23 des Dichtungsschenkels 19 eine Breite von 1,6 mm aufweist und sich die Spitze um 2,4 mm von der inneren Seitenfläche des Dichtungsschenkels 19 erhebt.It has also proven to be advantageous if the side surface of the sealing leg 19 around a certain dimension M is arranged offset. It has turned out to be particularly advantageous. if, for example, the sealing leg has a height of 5.69 mm with respect to the web surface 29, the Tip spaced 5.5 mm from the web surface 29 the end face 23 of the sealing leg 19 has a width of 1.6 mm and the tip around 2.4 mm from the inner side surface of the sealing leg 19 rises.

Auf vorteilhafte Weise kann in der Wandung des Bodenteils 1B eine Nut 27 (gestrichelt dargestellt) vorgesehen sein, in die der Vorsprung 21 des Dichtungsschenkels 19 eingefügt werden kann.Advantageously, in the wall of the bottom part 1B a groove 27 (shown in broken lines) be provided, in which the projection 21 of the sealing leg 19 can be inserted.

in Fig. 5 ist eine ebenfalls vorteilhafte Ausgestaltung insbesondere der Stirnfläche des Dichtungsschenkels gezeigt. Diese Stirnfläche zeichnet sich dadurch aus, daß sie materialverstärkt ausgebildet ist, vorzugsweise in der Seitenansicht spitz nach oben zulaufend.5 is a likewise advantageous embodiment especially the end face of the sealing leg shown. This end face is characterized by it from that it is material-reinforced, preferably in the side view tapering to the top.

In Fig. 6 ist eine weitere vorteilhafte Ausgestaltung der Wandung der Vertiefung gezeigt. Die schräg verlaufende Einlauffläche 31 geht in eine vertikal verlaufende Auflagefläche 33 über, die dann wiederum eventuell in eine schräg verlaufende Wandung der Vertiefung 5A, 5B, 5C übergehen kann. Zwischen der Einlauffläche und der vertikal verlaufenden Auflagefläche bildet sich eine Kantenlinie 37 über die der Dichtungsschenkel 19 samt Vorsprung 21 beim Verschließen des Behältnisses geführt wird. Der in Fig. 6 gezeigte spitz zulaufende Vorsprung dichtet lediglich an einer vorgegebenen Stelle auf der Auflagefläche ab. Zusätzlich ist in Figur 6 auch die Rillenstruktur R eingezeichnet, wobei allerdings in der Seitenansicht gemäß Fig.6 der Schnitt durch ein Rillental erfolgt. Mit dieser Rillenstruktur wird erreicht, daß zum einen der beim Zusammenfügen des Boden- und des Deckelteils sich normalerweise aufbauende Überdruck im Inneren der abzudichtenden vertiefungen verhindert wird und zum anderen kann durch spezielle Rillenführung der Rillenstruktur einem Staucheffekt der Dichtungslippe, insbesondere im Krümmungsbereich der Vertiefungen, entgegengewirkt werden.6 is a further advantageous embodiment shown the wall of the recess. The weird extending inlet surface 31 goes into a vertical one Support surface 33, which in turn possibly in a sloping wall of the recess 5A, 5B, 5C can pass over. Between the inlet area and the vertical contact surface an edge line 37 forms over which the sealing leg 19 together with projection 21 when closing the Container is performed. The pointed shown in Fig. 6 tapering projection only seals against a predetermined one Place on the support surface. In addition is the groove structure R is also shown in FIG. 6, wherein however in the side view according to Figure 6 the section through a groove valley. With this groove structure achieved that on the one hand when the Bottom and lid parts normally build up Overpressure inside the recesses to be sealed is prevented and secondly by special groove guidance of the groove structure with a compression effect the sealing lip, especially in the area of curvature of the depressions are counteracted.

Vorstehend wurde lediglich ein Ausführungsbeispiel der geometrischen Ausgestaltung des inneren Dichtungsschenkels beschrieben. Selbstverständlich sind Abwandlungen der vorstehend beschriebenen Ausführungsform möglich, ohne den Grundgedanken der Erfindung zu verlassen.Above was just one embodiment the geometric design of the interior Sealing leg described. Of course are modifications of those described above Embodiment possible without the basic idea to leave the invention.
