Dichtungsring zum Abdichten eines Oberteils mit einem Unterteil sowie ein hierfür geeignetes Speisebehältnis Sealing ring for sealing a shell with a lower part and a suitable food container
Folgende Erfindung betrifft einen Dichtungsring zum Abdichten eines Oberteils mit einem Unterteil sowie ein hierfür geeignetes Speisebehältnis. The following invention relates to a sealing ring for sealing an upper part with a lower part and a feed container suitable for this purpose.
Herkömmiicherweise werden Dichtungringe bei der Verbindung von Speisebehältnissen vorrangig zum luftdichten Verschliessen der in dem Speisebehältnis enthaltenen Speisen verwendet. Derartige Dichtungsringe werden über die entsprechenden Elemente des Speisebehältnisses mittels eines Verschließmechanismuses verschlossen. Der mechanisch ausgestaltete Verschlußmechanismus kann beispielsweise als Schnappverschluß bzw. Klettverschluß ausgestaltet sein. Hierbei wird beispielsweise zwischen dem Unterteil und Oberteil des Speisebehältnisses den Konturen des Unterteils folgender Dichtungsring gelegt, der dann durch Zusammenpressen die Abdichtung des Speisebehältnisses mittels des Verschlußmechanismuses herbeiführt. Herkömmlicherweise wird somit zusätzlich ein Verschlußmechanismus für das Speiseverhäitnis benötigt. Traditionally, gaskets are used in the connection of food containers primarily for hermetically sealing the food contained in the food container. Such sealing rings are closed by means of a Verschließmechanismuses on the corresponding elements of the food container. The mechanically configured closure mechanism can be configured, for example, as a snap closure or Velcro closure. Here, for example, the contour of the lower part of the following sealing ring is placed between the lower part and the upper part of the food container, which then causes the sealing of the food container by means of the shutter mechanism by pressing together. Conventionally, therefore, a closing mechanism for the feed ratio is additionally required.
Es ist somit Aufgabe der vorliegenden Erfindung, die Nachteile des Standes der Technik zu vermeiden. Ferner ist es Aufgabe der Erfindung, einen Dichtungsring bereitzustellen, der eine selbstsichernde Abdichtung eines Speisebehältnisses bestehend aus einemIt is therefore an object of the present invention to avoid the disadvantages of the prior art. It is another object of the invention to provide a sealing ring having a self-locking seal of a food container consisting of a
Ober- und Unterteil herbeiführt. Upper and lower part brought about.
Gelöst werden diese Aufgaben mit den erkmalen der Ansprüche 1 oder 1 1. These objects are achieved by the features of claims 1 or 11.
Anmeldungsgemäß wird ein Dichtungsring mit Einfassungsrand bereitgestellt, der imAccording to the application, a sealing ring with edging edge is provided, which in the
Querschnitt einen ersten Hinterschnitt zur Aufnahme des Oberteils und einen zweiten Hinterschnitt zur Aufnahme des Unterteils aufweist. Mittels dieser Hinterschnitte wird erreicht, dass nach Zusammenfügen des Ober- und Unterteils ein Herausgleiten der jeweiligen Teile verhindert wird. Um die selbstsichernde Funktion des Dichtungsrings zu ermöglichen, weist der Dichtungsring ferner zwischen dem ersten und zweiten Hinterschnitt einen Verbindungsschenkel auf. an dessen Ende ein Stellhebel vorgesehen ist. Beim Zusammenfügen eines Unter- und Oberteils eines Speisebehälters wird durch entsprechende Formgebung des Oberteils der Stelihebel zum Speisebehältnisinneren ausgelenkt und somit eine Zugspannung in dem Verbindungsschenkel erzeugt. Die selbstsichernde Abdichtung wird insbesondere dann erreicht, dass nach Einführen des Unterteils in den breiten Hinterschnitt über den ausgelenkten Stellhebel der erste Hinterschnitt in Richtung des Stellhebels gezogen wird und nach Einfügen des Oberteils mittels Zugspannung und Auslenkung des ersten Hinterschnitts die selbstsichernde Funktion des Dichtungsrings gegeben ist. Aufgrund der nach außen gerichteten Auslenkung des ersten Hinterschnitts wird somit der zweite Hinterschnitt an den Außenumfang des Unterteils herangedrückt, wodurch zum einen die Abdichtung und zum anderen der Verschluß des Speisebehältnisses herbeigeführt wird. Cross-section has a first undercut for receiving the upper part and a second undercut for receiving the lower part. By means of these undercuts it is achieved that after joining the upper and lower part, a sliding out of the respective parts is prevented. In order to enable the self-locking function of the sealing ring, the sealing ring further comprises a connecting leg between the first and second undercut. at the end of a lever is provided. When joining a lower and upper part of a food container is deflected by appropriate shaping of the upper part of the Stelihebel to the food container interior and thus generates a tensile stress in the connecting leg. The self-locking seal is achieved, in particular, that after insertion of the lower part in the wide undercut over the deflected lever the first undercut is pulled in the direction of the control lever and after insertion of the upper part by means of tension and deflection of the first undercut the self-locking function of the sealing ring is given. Due to the outward deflection of the first undercut thus the second undercut is pressed against the outer periphery of the lower part, whereby on the one hand the sealing and on the other hand, the closure of the food container is brought about.
Weitergehende vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche Further advantageous embodiments are the subject of the dependent claims
Weist der Steilhebel gemäß Anspruch 2 eine elastische Biegeverformung beim Zusammenfügen von Ober- und Unterteil des Speisebehäitnisses auf. so ist insbesondere das Verschliessen des Speisebehältnisses auf einfache Weise gewährleistet und unterstützt den selbstsichernden Abschluß des Speisebehältnisses. The wedge lever according to claim 2, an elastic bending deformation during assembly of the upper and lower part of the food supply. in particular, the closure of the food container is ensured in a simple manner and supports the self-locking closure of the food container.
Ferner wird zusätzlich über die elastische Biegeform gemäß Anspruch 3 des den ersten Hinterschnitt enthaltenen Teil des Einfassungsrandes eine weitere Spannwirkung erzeugt, die im Zusammenwirken mit der Biegeverformung hinsichtlich des weiten Hinterschnitts eine besondere Abdichtung unterstützt. Furthermore, a further clamping effect is additionally generated on the elastic bending mold according to claim 3 of the first undercut portion of the skirting edge, which supports in cooperation with the bending deformation with respect to the wide undercut a special seal.
Wird ferner gemäß Anspruch 4 eine Innenform des Dichtungsrings vorgesehen, die die Verbindungselemente zwischen dem Einfassungsrand enthält, so wird zusätzlich zu der nach außen hin vorzunehmenden Abdichtung des Speisebehältnisses auch eine Unterteilung der jeweiligen Behältnisteile erreicht. Vortei!hafterweise wird diese Abdichtungsfunktion über eine Dichtfläche zur Auflage auf dem Unterteil und eine Dichtungslippe zum Anlagekontakt zum Oberteil erreicht. Further, according to claim 4, an inner shape of the sealing ring is provided, which contains the connecting elements between the skirt edge, so in addition to the outward to be carried out sealing of the food container, a subdivision of the respective Behältnisteile is achieved. Advantageously, this sealing function is achieved by means of a sealing surface for resting on the lower part and a sealing lip for abutting contact with the upper part.
Um herstellungsbedingte Toleranzen auszugleichen, ist es von Vorteil, wenn die Dichtungslippe im Querschnitt ein Basiselement mit aufgesetztem Mittelelement, auf welchem ein wellenkammartiges Dichtungsband positioniert ist, gestaltet wird. Aufgrund des wellenkammartigen Dichtungsbandes können somit, insbesondere bei der Porzellanherstellung auftretende Toleranzunterschiede ausgegelichen werden. To compensate for manufacturing tolerances, it is advantageous if the sealing lip in cross-section a base element with attached central element, on which a wave comb-like sealing strip is positioned, is designed. Due to the wave-comb-like sealing strip can thus be compensated, especially in the production of porcelain tolerance differences.

The design of the Stellhebeis 7 is such that the actuating lever tip can be inserted into a lever armature channel of the upper part and due to the geometrical dimensions, the outer border of the upper part in the undercut A can be introduced and aligns the first undercut A contained part of the skirt edge to the outside. Due to the nature of the material, the deflection of the first undercut A contained portion of the skirt edge is aligned outward. Due to the nature of the material, the deflection of the part of the edging edge contained in the first undercut A results in a deflection of the part containing the second undercut B and thus in a prestress.
In Figur 2 ist der an dem Oberteil vorgesehene Dichtungsring dargestellt, der auf das Unterteil aufgesetzt wird. Hierbei verbleibt der Außenumfang im ersten Hinterschnitt A des Einfassungsrandes und der Stellhebel wird durch den Außenumfang des Unterteils in dem Steilhebelkanal des Oberteils gebracht, wobei über die Kontaktfiäche des Stellhebels eine Auslenkung und Vorspannung des Verbindungsschenkels erreicht Zusätzlich wird über den zweiten Hinterschniit B des Einfassungsrandes der Außenumfang des Unterteils in den zweiten Hinterschnitt B eingebracht, wodurch der selbstsichernden Verschluß des Speisebehältnisses aber auch die Abdichtung nach außen hin herbeigeführt wird. In Figure 2, provided on the upper part of the sealing ring is shown, which is placed on the lower part. Here, the outer circumference remains in the first undercut A of the edging edge and the adjusting lever is brought by the outer periphery of the lower part in the Steilhebelkanal of the upper part, wherein on the Kontaktfiäche the adjusting lever reaches a deflection and bias of the connecting leg addition is on the second Hinterschniit B of the edging edge of the outer circumference of the lower part introduced into the second undercut B, whereby the self-locking closure of the food container but also the seal is brought to the outside.
Anhand dieses Verschlußmechanismus wird insbesondere bei herstellungsbedingten Toleranzen, die vorzugsweise bei dem Material von Porzellan unausweichlich sind, vollständig Rechnung getragen, da die jeweiligen Vorspannungen und Hinterschnitte den Toleranzen des Materials entgegenwirken können. On the basis of this closure mechanism is fully taken into account especially in manufacturing tolerances, which are preferably inevitable in the material of porcelain, since the respective biases and undercuts can counteract the tolerances of the material.
Ist insbesondere der mit dem Außenumfang in Verbindung stehenden Teil des Verbindungsschenkels kürzer als der Außenumfang bis zum Kontaktpunkt mit der Kontaktfläche, so wird durch diese Vorspannung das Anhaften des Dichtungsrings an das Oberteil gewährleistet und es kann somit über diese Vorspannung das Ablösen vom Unterteil isoliert werden. If, in particular, the part of the connecting leg which is in contact with the outer circumference is shorter than the outer circumference up to the point of contact with the contact surface, this prestressing ensures the adhesion of the sealing ring to the upper part and thus the detachment from the lower part can be isolated via this pretensioning.
Ferner wird durch den umlaufenden Stellhebelkanal der Deckel massiv versteift. Dies ist insbesondere von Vorteil, wenn durch die Höhe des Stellhebelkanals die Schwachstellen zwischen den Kammern wesentlich gestärkt werden. Dies ist immer insbesondere dann von Vorteil, wenn beim Abnehmen des Deckels das Porzellan umlaufend gleichmäßig mittels Daumendruck vom Deckel gedrängt wird. Beim Abnehmen des Oberteils wird folgendermaßen vorgegangen: Der Dichtungsring wird mit beiden Händen rechts und links im Bereich von vorgesehenen Löchern im Deckel nach außen gezogen und gleichzeitig nach oben. Furthermore, the cover is massively stiffened by the rotating lever armature channel. This is particularly advantageous if the weak points between the chambers are significantly strengthened by the height of the actuating lever channel. This is always particularly advantageous if, when removing the cover, the porcelain circumferentially evenly pushed by thumb pressure from the lid. When removing the upper part, the procedure is as follows: The sealing ring is pulled with both hands right and left in the range of holes provided in the lid to the outside and at the same time upwards.
Durch diese Maßnahme wird erstens ein eventuell bestehendes Vakuum bzw. Unterdruck gelöst. Im weiteren Vorgang wird das Porzellan aus dem zweiten Hinterschnitt des Verschlusses gedrückt. Gleichzeitig wird umlaufend der Stellhebel aus dem Stellhebelkana! gezogen und bleibt in Stellung wie in Figur 2 dargestellt. By this measure, first, any existing vacuum or vacuum is solved. In the further process, the porcelain is pressed out of the second undercut of the closure. At the same time, the adjusting lever from the control lever can be turned! pulled and remains in position as shown in Figure 2.
Da der Dichtungsring in aufgedehnter Form mit Hinterschnitt im Deckel fest verankert ist, ist es bei jeder Form des Abnehmens sichergestellt, dass der Dichtungsring immer mit dem Deckelteil fest verbunden bleibt. Aufgrund der besonderen geometrischen Gestaltung des Außenumfangs des Oberteils mit Stellhebelkanal wird erreicht, dass so gut wie kein Kontakt bzw. nur 1 bis 2 % zwischen den Speisen und Abdichtung mittels Dichtungsring erfolgt, obwohl der Dichtungsring - in getempertem Zustand - lebensmittelecht ist. Since the sealing ring is firmly anchored in an expanded form with undercut in the lid, it is ensured at every form of removal that the sealing ring always remains firmly connected to the lid part. Due to the special geometric design of the outer circumference of the upper part with lever channel is achieved that virtually no contact or only 1 to 2% between the food and sealing by means of sealing ring, although the sealing ring - when tempered - is food safe.
In Fig 4a wird ein Querschnitt des anmeldungsgemäßen Dichtungsringes in der Innnenform gezeigt. Diese Dichtungslippe des Dichtungsrings zeigt einen dreiteiligen Aufbau. Auf die Grundebene G, welche unterseitig mit dem Unterteil in Anlagekontakt kommt, ist eine Mittelebene M vorgesehen, welche gegenüber der Grundebene G verjüngt ausgestaltet ist, um herstellungsbedingte Materialvorgaben Rechnung trägt. Auf die Mittelebene M ist ein Wellenkamm W vorgesehen, der wiederum gegenüber der Mittelebene M im Querschnit verjüngt ausgestaltet ist. Der Wellenkamm W dient zum Anlagekontakt und der Abdichtungsfunktion gegenüber dem Oberteil. In Fig 4b ist die Wellenkammform aus der Seitenansicht dargestellt. Über die Wellenkammform der Dichtungslippe wird einem Stauchungseffekt beim zusammengefügten Behältnis entgegengewirkt. Die Wellenkammform in der Innenform wird bei einem mehrteiligen, konturengleichem Ober- und Unterteil eingesetzt und vorzugsweise jeweils beginnend von den seitlichen Zwickel bis zur Vorderkante des Behältnisteils in der Dichtungslippe vorgesehen. In Fig. 4a ist ebenso die Formgebung des Oberteils in der Innenform vorgesehen. Ferner sind Stabilisierungsbereiche S beabstandet zu der Mittelebene an dem Dichtungsring vorgesehen. Die Stabilisierungsbereiche dienen zusätzlich der Lagefixierung des Oberteils beim Zusammenfügen des Speisebehältnisses. In Fig 4a, a cross section of the sealing ring according to the invention is shown in the Innnenform. This sealing lip of the sealing ring shows a three-part construction. On the ground plane G, which comes into abutting contact with the lower part, a median plane M is provided, which is designed to be tapered with respect to the ground plane G, taking into account production-related material specifications. On the median plane M, a wave crest W is provided, which in turn is designed to be tapered with respect to the median plane M in the cross section. The wave crest W is used for contact and the sealing function relative to the upper part. In Fig 4b, the wave crest shape is shown from the side view. About the wave crest shape of the sealing lip is a compression effect counteracted in the assembled container. The wave crest shape in the inner mold is used in a multi-part, contour-identical upper and lower part and preferably provided in each case starting from the side gusset to the front edge of the container part in the sealing lip. In Fig. 4a, the shape of the upper part is also provided in the inner mold. Furthermore, stabilization regions S are provided at a distance from the center plane on the sealing ring. The stabilization areas additionally serve to fix the position of the upper part when assembling the food container.
In den Fig. 5a bis 7 sind jeweils die Unter- und Oberteile des Behältnisses gezeigt, welche mit dem anmeldungsgemäßen Dichtungsring verbunden stappelbar sind. Ferner ist in Fig. 8 eine Stapelbarkeit des Unter- und des Oberteils mit dem Dichtungsring dargestellt. In Figs. 5a to 7, respectively, the lower and upper parts of the container are shown, which are connected stappelbar connected to the application according to the sealing ring. Furthermore, a stackability of the lower and the upper part is shown with the sealing ring in Fig. 8.
