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 12.The invention relates to a container for food, especially for serving, storage, and Transporting food or the like according to the Preamble of claim 1, and in particular one suitable for sealing the container Sealing body according to the preamble of the claim 12th

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 are regularly used when it comes to food, especially hot food, put together in a commercial kitchen and then through a suitable logistics system for end users, such as delivering hospitals or the like. A container of the type described above is for example in the earlier patent applications P4325205, P4410943, P4410945, 19506394, P19526719 or 19528771 of the applicant. The revelation content of these earlier patent applications is said to be in this present patent application are 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 cover part with good sealing the depressions provided therein with each other can be connected. To get a good seal, has so far been at least one deepening for example, the base part encircling sealing body thought of at least one elastic Has sealing leg over which the seal with the cover part was achieved. Serves as a sealing surface here a side surface of the sealing leg. Based this flat contact of the sealing leg Attempting to seal the wall was attempted to reach. However, experiments that such sealing measures are only limited can be maintained.

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 To further develop the container of the type described in the introduction, that the sealing measures are improved. Another object of the invention is to provide a To create sealing body, which also improved Sealing measures enabled.

Diese Aufgabe wird hinsichtlich des Behältnisses mit den Merkmalen des Anspruchs 1 und hinsichtlich des Dichtungskörpers mit den Merkmalen des Anspruchs 12 gelöst.This task is related to the container the features of claim 1 and in terms of Sealing body solved with the features of claim 12.

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 hervorgerufene 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 is used to seal a floor or cover part of the container used sealing leg of the sealing body with a projection provided, for sealing the base or cover part is pressed against the wall of the recess. With this measure, the sealing leg with a for example to provide a nose-like projection possible, the contact surface or contact surface between Sealing leg and wall of the recess targeted to determine or set, so that by pressurization caused by the elastic sealing leg if necessary also optimized increased can be. This measure also achieves that the high demands on the production or Handling of those touching in the plane surface system Surfaces are reduced without the Sealing properties are influenced. In addition, according to the invention by the formation of the sealing leg achieved with a head start that over the geometric design or dimensioning (height, Width, shape) for a given elasticity of the sealing leg the pressure on the wall the depression can be adjusted. With given elasticity can also, for example deflection caused by the wall of the depression of the sealing leg set or optimized become. The specified elasticity of the sealing leg is also suitable, possibly occurring tolerances of the soil or to be sealed Compensate cover part.

Die eben aufgeführten Vorteile treffen auch auf den mit Anspruch 12 definierten Dichtungskörper zu.The advantages just mentioned also apply to the Claim 12 defined sealing body.

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

Es ist besonders vorteilhaft, 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.It is particularly advantageous if the Wall of the recess has a bearing surface arranged vertically opposite the projection is, and also serves as a sealing surface. It is also an advantage if the wall a sloping one above the contact surface Has inlet area to the sealing leg through deflect an elastic bending. By this special design of the wall is achieved that the sealing leg with a projection in a force horizontal direction on the wall. Thereby is prevented by the bending elasticity of the Sealing leg a force in the vertical direction is exercised if, for example, the contact surface would also run obliquely, causing the vertical Power components cause the container to open would. If the bearing surface of the wall against the not deflected sealing leg offset arranged, preferably by 1.4 and 1.9 mm, each according to the elasticity of the sealing leg and length of the Sealing leg achieved that when merging or closing the container of the sealing legs touches down on the sloping inlet surface and to the offset between the vertical contact surface for the projection of the sealing leg and not deflected seal leg is deflected. The Inlet surface and the contact surface form one Edge line over which the deflected sealing leg with a lead. Care is taken that only the projection of the sealing leg with the Wall comes into contact with the system and thus from the oblique running inlet area over the edge line on the Support surface under elastic bending deformation of the Seal leg is performed, it is achieved that a kind of snap effect is provided. Because after the sealing leg on the The sealing leg is 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 Gasket leg can extend down towards the Relax the support surface. This will make a This creates a snap effect that includes the sealing leg Bring the projection into the optimal predetermined position can. Due to the vertical contact surface achieved a reduced horizontal force is generated, which is a drifting apart of the two Can cause parts of the container.

Weist die Einlauffläche ferner 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.At least has the inlet surface sections of a groove structure, so is on easily provided a measure with which a itself when the container is sealed airtight any overpressure that builds up is checked and possibly avoided. Thereby is achieved that when closing the Sealing lip initially 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 the sealing lip is along the inlet surface continued, the one by merging pressure occurring above that of the sealing lip is not fully sealed groove structure from the The interior of the container can escape. Are the two items of the container in such a way moving towards each other that possibly on the container existing locking mechanism can be operated, the sealing lip changes from the inlet surface the sealing surface over. This measure will achieved that only one in the last phase of Closing the container creates an overpressure. However, this minimal excess pressure can be used by anyone and without special technical effort and without special effort can be overcome. Characterized in that the inlet surface with a groove structure is provided, the sealing lip does not have to be any more be subjected to special design, since the Grooves a sufficiently large passage for the overpressure provide.

Wird z. B. gemäß Anspruch 4 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 4 of the projection at the end of Sealing leg provided, so is one with sealing leg with low elasticity due to the leverage, a large pressurization on the wall of the depression 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, so is the pressure created by the sealing leg acts together with the projection on the wall transfer the tapering or rejuvenation to a line, and thus also optimized.

Es hat sich gezeigt, daß gemäß Anspruch 6 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 6 it is particularly The advantage is if the tip of the projection is one Has opening angle of 90 ° and a side surface of the tapered projection with the sealing leg forms an angle of 150 °. With this configuration it is ensured that the tip or the End point of the projection when closing the lid part with the bottom part does not turn over or bend is, which otherwise affects the sealing properties per se would be. It should also be noted that this special top design of the lead also for the Practice shows the best sealing properties and thus most suitable for everyday use proved.

Wird hingegen gemäß Anspruch 7 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. In contrast, according to claim 7, the lead in the contact area rounded off with the wall of the depression trained with this geometric design achieved that on the one hand with particularly heavy use nevertheless reduced to a minimal area and thus ensures increased pressurization will, and on the other hand, about sizing the rounding, i.e. by suitable choice of the radius, the pressurization can also be influenced.

Die Dichteigenschaften des Behältnisses können auch in vorteilhafter Weise gemäß Anspruch 8 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 be in advantageously increased or influenced according to claim 8 be by for the ledge in the wall the depression a the projection in the closed state opposite groove provided in the container is. For example, the depth of the groove or but also by another geometric design the groove determines the sealing area and if necessary specific to the requirements be aligned.

Darüberhinaus kann es gemäß Anspruch 9 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, it can be advantageous according to claim 9 be 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 account wear to optimally design the seal.

Auf die Vorteile der Merkmale des Anspruchs 10 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 claim 10 will in particular to patent application 19506394 referenced, the subject of which is in particular a molded sealing body concerned on a cover part and hereby fully in the disclosure content this patent application is included.

Darüberhinaus ist es vorteilhaft, wenn sich der Dichtungsschenkel nicht innenseitig an die Wandungen der Vertiefungen anlegt, sondern gemäß Anspruch 11 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 Creates wells, but each according to claim 11 Recess has a web-like border and the Sealing leg pressed against the frame from the outside becomes. In this case it points from the recess facing away from the outer surface of the wall the oblique running inlet surface and the vertical one Contact surface. This particular arrangement will achieved that, especially when a negative pressure in the Wells is created, a secure seal is guaranteed. in addition, the Negative pressure and the bending elasticity of the sealing leg the sealing leg against the outside the web-like edging pressed. Here too through that of the inlet surface and the vertical arranged contact surface generated edge line and the associated snap function the locking function supported.

Die für die Ansprüche 2 bis 11 beschriebenen Vorteile gelten auch für den mit Anspruch 12 definierten Dichtungskörper an sich, so daß von einer Wiederholung der Argumente abgesehen wird.The advantages described for claims 2 to 11 also apply to the sealing body defined in claim 12 in itself, so that from repeating the Arguments apart.

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 1B 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 1A 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 for explanation as an example from the Applicant's patent application P4410943 or 19506394 container 1 shown for explanation. The Container 1 has a cover part 1A and one with identical cup-shaped contours formed bottom part 1B, in this example the cover part 1A a sealing body 3 permanently attached, preferably is molded. The container shown in Fig. 1 has three as food storage sections acting recesses 5A, 5b and 5c. In the side Middle region 7 of the cover part 1A are preferred on one side a tab 9 for example in Form of a material hinge and a hole 11 formed used to open the container. 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 1A 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 1A an sich.In Fig. 2, the cover part of FIG. 1 from below shows, it can clearly be seen that opposite to Gusset area 7 at the edge 13 of a locking section 15 is formed. As in the sectional view along the section III-III in Fig. 2 more clearly 3, the locking section has 15 a hook 17 as a rear grip, in the the border edge 13 of the congruent bottom part 1B, can be attached. The one shown in this example molded sealing body 3 has - as Fig. 3 shows - an inner part of the cover part 1A Sealing leg 19 on. The inner sealing leg 19 of the sealing body 3 is from another Material, especially softer or more elastic Material formed as the lid part 1A 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 is the nose-like Projection 21 provided, tapering here is shown. If the container is now closed, d. H. the border edge 13 of the bottom part 1B is engaged by the hook 17 of the cover part 1A, so the elastic sealing leg 19 is corresponding the slope of the wall of the depression 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 presses. In this way the container is sealed.

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 follows coordinated, exemplified here Contains dimensions. So it is an advantage if the tip of the projection has an angle of 90 ° and the side surface of the sealing leg 19 with the Side surface of the projection 21 an angle of 150 ° forms.

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 by a certain Dimension M is arranged offset. It also 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 around 5.5 mm from the web surface 29, the End face 23 of the sealing leg 19 a width of 1.6 mm and the tip is 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 dashed lines) is provided into 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 shown in particular the end face of the sealing leg. This end face is characterized in that it is material-reinforced, preferably in the side view tapering upwards.

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 running inlet surface 31 goes vertically extending bearing surface 33, which in turn possibly in an inclined wall of the Recess 5A, 5B, 5C can pass. Between the Inlet surface and the vertical Contact surface forms an edge line 37 over the the sealing leg 19 together with the projection 21 at Closing the container is performed. The in Fig. 6 shown tapered projection only seals at a predetermined location on the contact surface. In addition, the groove structure R is also in FIG drawn in, but in the side view 6, the section is made through a groove valley. With this groove structure it is achieved that, on the one hand the when joining the bottom and the lid part normally build up excess pressure inside the wells to be sealed is prevented and others can be achieved through special groove guidance Groove structure a compression effect of the sealing lip, especially in the area of curvature of the depressions, be 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 only one embodiment of the geometric design of the inner sealing leg described. Variations are natural the embodiment described above possible without leaving the basic idea of the invention.
