Description

Verschliß zur Schaffung eines vakuuηgeeigneten Gastronoπrbehälters Wear it to create a vacuum-suitable food container
B e s c h r e i b u n gDescription
Die Erfindung betrifft einen Verschluß für Spezialbehäl¬ ter, insbesondere Gastronormbehälter, die zur Aufnahme von verderblichen Waren vorgesehen sind, wobei Deckel und Spezialbehälter mit einem korrespondierenden Rand ausgerüstet sind.The invention relates to a closure for special containers, in particular gastronorm containers, which are provided for receiving perishable goods, the lid and special container being equipped with a corresponding edge.
Es ist üblich, zur langfristigen oder auch kurzfristigen Aufbewahrung von Lebensmitteln diese unter Vakuum zu halten, um so sowohl den Kontakt mit dem Sauerstoff zu verhindern wie auch einen Aromaschwund zu verhindern oder zu verzögern. Hierbei erfolgt die Aufbewahrung in verschiedenartig großen Behältern oder auch in Folien oder Beuteln. Allerdings fehlt es an praktikablen Behältern für kleinere Verpackungsmengen. Vor allem an solchen Behältern, die sowieso bereits im Ge¬ brauch sind, um solche Lebensmittel oder sonstige Waren auf¬ zubewahren. Grund hierfür ist vor allem, daß diese Behälter so ausgebildet sind, daß ihre Wandungen die Erzeugung von Vakuum nicht zulassen.For long-term or short-term storage of food, it is customary to keep it under vacuum in order to both prevent contact with the oxygen and prevent or delay the loss of aroma. Storage takes place in containers of various sizes or in foils or bags. However, there is a lack of practical containers for smaller packaging quantities. Especially on those containers that are already in use anyway in order to store such foods or other goods. The main reason for this is that these containers are designed in such a way that their walls do not permit the generation of a vacuum.
Aufgabe der vorliegenden Erfindung ist es, einen Behäl¬ ter, insbesondere Gastronormbehälter zu schaffen, der die Erzeugung eines Unterdruckes ermöglicht.The object of the present invention is to create a container, in particular a gastronorm container, which enables a negative pressure to be generated.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Deckel einen gestuften Rand mit Abdeckfläche und an die seit¬ liche Wandung des Spezialbehälters anliegende Abstützfläche aufweist, daß der Deckel biegesteif ausgebildet ist, an der Abdeckfläche ein Dichtelement und eine Schneilver- schlußrüσkschlagkupplung bzw. Ventil aufweist.The object is achieved according to the invention in that the cover has a stepped edge with a cover surface and a support surface lying against the side wall of the special container, in that the cover is designed to be rigid, has a sealing element on the cover surface and a Schneilverschlußschlüσkkschlagkupplung or valve.
Vorteilhafterweise kann dabei auf Gastronormbehälter zurückgegriffen werden, die einfach nur mit einem ent¬ sprechenden Deckel versehen werden, der nicht nur die für die Erzeugung des ünterdrucks notwendigen Ventil- oder Verschlu߬ anordnungen aufweist, sondern der auch als solcher zur Aus¬ steifung des Gastronormbehälters oder sonstigen BehältersAdvantageously, gastronorm containers can be used which are simply provided with a corresponding cover which not only has the valve or closure arrangements necessary for generating the negative pressure, but also as such for stiffening the gastronorm container or other container
ERSAT2BLATT dienen kann. Der Gastronormbehälter stützt nämlich durch den gestuften Rand die seitliche Wandung des Spezialbehälters ab, die auf diese Art und Weise ausgesteift wird. Dabei ist be¬ sonders vorteilhaft, daß bereits vorhandene Gastronormbehäl¬ ter nachgerüstet werden können, so daß dem Anwender minimale Kosten entstehen. Die Behälter sind dann wie bisher einsetz¬ bar und zusätzlich als Vakuumbehälter zu verwenden. Dabei entfällt zeitraubendes Umfüllen in Folien und Vakuumbeutel, weiter entfällt der dadurch anfallende Schwund, dasselbe gilt für das Herausnehmen aus den Folien oder Vakuumbeuteln und es entfällt schließlich das Entsorgungsproble der meist koex- trudierten Folien und Vakuumbeutel. Kühlprobleme entfallen zum größten Teil dadurch, daß im Gegensatz zu Großbehältern das unter Vakuum befindliche Gut direkten Kontakt zum Behäl¬ ter hat und dadurch Kühlprobleme wie bei Großbehältern durch Fehlen wärmeleitender Medien bzw. Wände nicht entstehen. ERS AT2BLATT can serve. Because of the stepped edge, the gastronorm container supports the side wall of the special container, which is stiffened in this way. It is particularly advantageous that existing gastronorm containers can be retrofitted so that the user incurs minimal costs. The containers can then be used as before and can also be used as vacuum containers. There is no time-consuming refilling in foils and vacuum bags, further the shrinkage is eliminated, the same applies to removal from the foils or vacuum bags and the problem of disposal of the mostly co-extruded foils and vacuum bags is eliminated. Cooling problems are largely eliminated by the fact that, in contrast to large containers, the material under vacuum has direct contact with the container, and cooling problems, as in the case of large containers, do not arise due to the lack of heat-conducting media or walls.
Nach einer zweckmäßigen Ausführung der Erfindung ist vorgesehen, daß der Deckel aus durchsichtigem Kunststoff be¬ steht. Dadurch ist es leicht möglich, den Inhalt des Behäl¬ ters als solchen auszumachen und zu identifizieren.According to an expedient embodiment of the invention it is provided that the cover is made of transparent plastic. This makes it easy to identify and identify the contents of the container as such.
Eine weitere zweckmäßige Ausführung sieht vor, daß der Deckel mit einem randseitig angeordneten Ventil versehen ist. Dieses Ventil ermöglicht insbesondere das Aufheben des Vaku¬ ums, wenn man beispielsweise die Speisen oder sonstigen Stof¬ fe aus dem Gastronormbehälter oder sonstigen Behälter heraus¬ nehmen will. Die Zuordnung zum Rand beläßt dem Gastronormbe¬ hälter die Stapelbarkeit. Bei einem durchsichtigen Deckel entfällt vorteilhaft übrigens das Kennzeichnen des Behälters bzw. des Inhaltes.Another expedient embodiment provides that the cover is provided with a valve arranged on the edge. This valve in particular enables the vacuum to be released if, for example, the dishes or other substances are to be removed from the gastronorm container or other container. The assignment to the edge leaves the gastronorm container stackable. With a transparent lid, the labeling of the container or the content is advantageously omitted.
Zur optimalen Reinigung des Gastronorm- o. ä. Behälters ist es von Vorteil, wenn das Dichtelement lösbar an der Ab¬ deckfläche angebracht ist, weil dadurch eine getrennte Rei¬ nigung möglich wird. Eine leichte Montage und Demontage des Ventils ist dadurch möglich, daß Ventil und Deckel mit korre- spondierenden Gewinden versehen sind und zwischen beiden Tei¬ len ein Dichtring angeordnet ist. Neben der Ausbildung als Deckel mit gestuftem Rand kann er auch gemäß der Erfindung einen genuteten Rand aufweisen, was den Vorteil hat, daß gleichzeitig auch eine seitliche Fixierung des Deckels noch gegeben ist, so daß ein genauer Paßsitz von vornherein ge¬ währleistet ist und damit eine sichere Abstützung und Stabi¬ lisierung des oberen Randes des Behälters. Will man besonders hohen Druck erzeugen oder aber entsprechend höhere Temperatu¬ ren der Speisen im Behälter ermöglichen, so ist es zweckmä¬ ßig, wen der Deckel aus Metall besteht.For optimal cleaning of the gastronorm or similar container, it is advantageous if the sealing element is detachably attached to the cover surface, because separate cleaning is thereby possible. Easy assembly and disassembly of the valve is possible by having the valve and cover with the correct sponding threads are provided and a sealing ring is arranged between the two parts. In addition to the design as a cover with a stepped edge, it can also have a grooved edge according to the invention, which has the advantage that the cover is also laterally fixed, so that a precise fit is guaranteed from the outset and thus a secure support and stabilization of the upper edge of the container. If it is desired to generate particularly high pressure or to enable correspondingly higher temperatures of the dishes in the container, it is expedient if the lid is made of metal.
Die Erfindung zeichnet sich insbesondere dadurch aus, daß durch die Eigenstabilität und die besondere Ausbildung des Deckels die Möglichkeit gegeben ist, auch in üblichen Gastronormbehältern o. ä. Kleinbehältern ein Vakuum zu erzeu¬ gen, das eine lange und sichere Lagerung von Speisen und son¬ stigen verderblichen Stoffen ermöglicht. Der ansonsten recht instabile Behälter wird durch die Stabilisierung im Deckelbe¬ reich bzw. im Bereich des oberen Randes so stabilisiert, daß die durch das Vakuum auftretenden Kräfte ohne Probleme aufge¬ nommen werden, wobei bei größeren Behältern unter Umständen der Boden durch entsprechende Verstärkungen oder Profile zu¬ sätzlich stabilisiert werden kann.The invention is characterized in particular by the fact that the inherent stability and the special design of the lid make it possible to generate a vacuum even in conventional gastronorm containers or similar small containers, which ensures long and safe storage of food and other items possible perishable substances. The otherwise quite unstable container is stabilized by the stabilization in the lid area or in the area of the upper edge in such a way that the forces arising from the vacuum are absorbed without problems, with larger containers possibly having the bottom by means of appropriate reinforcements or profiles can also be stabilized.
Weitere Einzelheiten und Vorteile des Erfindungsgegen¬ standes ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der ein bevorzugtes Ausführungsbei¬ spiel mit den dazu notwendigen Einzelheiten und Einzelteilen dargestellt ist. Es zeigen:Further details and advantages of the subject matter of the invention emerge from the following description of the accompanying drawing, in which a preferred exemplary embodiment is shown with the details and individual parts required for this. Show it:
Fig. 1 einen Gastronormbehälter mit Stabilisie¬ rungsdeckel im Schnitt, Fig. 2 einen Deckel mit genutetem Rand und Fig. 3 einen Deckel mit gestuftem Rand.1 a gastronorm container with a stabilizing lid in section, FIG. 2 a lid with a grooved edge and FIG. 3 a lid with a stepped edge.
Fig. 1 zeigt einen Gastronormbehälter 3, der über einen Deckel 1 verschlossen ist. Der Deckel 3 besteht hier bei¬ spielsweise aus durchsichtigem Kunststoff. Er verfügt einmal über einen gestuften Rand 10, wie er in Fig. 3 auch noch er¬ gänzend gezeigt ist und gemäß Fig. 2 und der die rechte Dar¬ stellung nach Fig. 1 über einen genuteten Rand 13. Zwischen Deckel 1 und oberem Rand des Spezialbehälters 3 ist ein Dichtelement 2 angeordnet, das lösbar mit der Abdeckfläche 11 verbunden ist. Entsprechendes zeigen Fig. 2 und 3.Fig. 1 shows a gastronorm container 3, which has a Cover 1 is closed. The cover 3 consists here, for example, of transparent plastic. It has a stepped edge 10, as it is additionally shown in FIG. 3 and according to FIG. 2 and the right illustration according to FIG. 1 has a grooved edge 13. Between cover 1 and the upper edge of the special container 3, a sealing element 2 is arranged, which is detachably connected to the cover surface 11. 2 and 3 show the same.
Mit 12 und 13 ist die seitliche Wandung und die Abstütz¬ fläche des Spezialbehälters 3 bezeichnet, wobei deutlich wird, daß hier diese einzelnen Flächen bzw. Wandungen durch die Sehne11verschlußrückschlagkupplung bzw. das Ventil 4 ein Unterdruck erzeugt werden kann, ohne daß die seitliche Wan¬ dung 15 des Spezialbehälters 3 sich wesentlich verformen kann. Nach relativ kurzem Verformungsweg stößt sie gegen die seitliche Wandung 15 des Deckels 1, so daß dann eine entspre¬ chende Stabilisierung eintritt.The side wall and the supporting surface of the special container 3 are designated by 12 and 13, it being clear that here these individual surfaces or walls can be created by the chord lock check coupling or the valve 4 without the lateral wall manure 15 of the special container 3 can deform significantly. After a relatively short deformation path, it abuts the side wall 15 of the cover 1, so that a corresponding stabilization then occurs.
Die Schnellverschlußrückschlagkupplung bzw. das entspre¬ chende Ventil ist durch den Dichtring 5 so abgedichtet, daß auch bei einer Einschraubversion, wie in Fig. 1 gezeigt, Un¬ dichtigkeiten nicht auftreten können.The quick-release check coupling or the corresponding valve is sealed by the sealing ring 5 so that even with a screw-in version, as shown in FIG. 1, leaks cannot occur.
Durch die Eigenstabilität des Deckels 1 und insbesondere durch das Randprofil bzw. den gestuften Rand 10 bzw. genute¬ ten Rand 13 erhält der ansonsten recht instabile Spezialbe¬ hälter 3 die notwendige Stabilität, um den beim Vakuum auf¬ tretenden Kräften standhalten zu können, wobei größere Behäl¬ ter unter Umständen im Boden z. B. durch Profile verstärkt werden können.Due to the inherent stability of the lid 1 and in particular due to the edge profile or the stepped edge 10 or grooved edge 13, the otherwise quite unstable special container 3 is given the necessary stability to be able to withstand the forces that occur in a vacuum, whereby Larger containers may be in the ground, e.g. B. can be reinforced by profiles.
Zum Evakuieren des Spezialbehälters 3 wird ein hier nicht dargestellter Schlauch zwischen Schnellverschlußrück- kupplung 4 und einer Hochleistungsvakuumpumpe oder einer Va¬ kuumverpackungsmaschine mit Vorrichtung zur Absaugung exter¬ ner Behälter aufgesteckt. Das Belüften des Spezialbehälters 3 geschieht durch Aufstecken nur des Schlauches auf die Schnellverschlußrückschlagkupplung 4, was zur Entriegelung der Schnellverschlußrückschlagkupplung 4 ausreicht, so daß die Belüftung des Spezialbehälters 3 erfolgt.To evacuate the special container 3, a hose (not shown here) is plugged between the quick-release feedback coupling 4 and a high-performance vacuum pump or a vacuum packaging machine with a device for extracting external containers. Aeration of the special container 3 happens by plugging only the hose onto the quick release check coupling 4, which is sufficient to unlock the quick release check clutch 4 so that the special container 3 is vented.
Alle genannten Merkmale, auch die den Zeichnungen allein zu entnehmenden, werden allein und in Kombination als erfin¬ dungswesentlich angesehen. All of the features mentioned, including those that can be seen in the drawings alone, are regarded as essential to the invention, alone and in combination.
