Definitions
- the invention relates to a deep-drawn metal container lid for a container with a beaded or rolled edge, which cover has a bottom with a travel tab and a peripheral edge which projects from the bottom and ends in a rolled edge.
- the prior art does not have any deep-drawn metal container lids for closing a container equipped with a bead or rolled edge.
- certain container lid related previously, in addition to deep drawing, a further manufacturing - step to connect to a container of the described construction form permitting locking members.
- the aim of the invention is to show a deep-drawn metal container lid for a container with a beaded or rolled edge which is exclusively deep-drawn.
- the invention solves the problem of creating a container lid for a container with a beaded or rolled edge, which has at least one wall section deformed against the inside of the lid in the peripheral edge.
- the advantage achieved by the invention can be seen essentially in the fact that a deep-drawn lid is created for a container with a rolled rim that can be easily removed from the container and is independent of the material of the respective container.
- the embodiment of the container lid shown in FIG. 1 is intended for use with a container having a beaded or rolled edge, which in turn is made of a metal or, for example, porcelain.
- a container having a beaded or rolled edge which in turn is made of a metal or, for example, porcelain.
- Such containers are used, for example, in air traffic, the contents of the container being heated for consumption in the galley.
- the container lid is a deep-drawn object made, for example, of aluminum or an aluminum alloy.
- the lid has a largely flat bottom 3. This bottom 3 is formed in one piece with a pull tab 4. The lid can be torn away from the container by means of this pull tab 4.
- the peripheral edge 5 protrudes from the bottom 3 of the lid, which ends in a rolled edge 6, as can be seen from FIGS. 2 and 3.
- the cover 3 can have a wide variety of shapes according to the container to be closed.
- the edge 5 can also have different cross-sectional shapes.
- the embodiment of the container lid shown is corresponding to a container 1 with a bead 2 forms, as indicated in FIGS. 2 and 3 in dashed lines.
- the edge 5 has at least one wall section 7 deformed towards the inside of the cover, as indicated in FIGS. 2 and 3.
- this deformed wall section 7 runs continuously along the peripheral edge 5.
- An embodiment is shown in FIG. 1 with the plurality of reference numerals 7, which contains four deformed wall sections 7.
- each deformed wall section is perforated, the perforation being a slot 10 running in the circumferential direction of the lid. This results in latching tabs 8, 9 that yield to the respective material and protrude obliquely from the inside of the lid.
- the container lid is provided with a pull tab 4 which is formed in one piece with the lid base 3.
- This tear-away tab 4 is separated from the rest of the lid base by a slot 11 which does not run in a straight line, see also FIG. 3.
- the slot 11 can consist of straight-line sections each enclosing an angle between them or, in the embodiment shown, in a straight line, for example semicircular run in shape.
- the lid base 3 now has an indented area in the area of the tear-off tab 4, which is indicated in FIGS. 1 and 3 by the reference number 12. The purpose of this training is explained below.
- the two ends of the approximately semicircular slot 11 are connected to one another by means of a groove 13, which groove 13 forms a closed figure running along the edge of the container for aesthetic reasons.
- This groove 13 connecting the two ends of the slot 11 extends approximately in a straight line. On the one hand, this results in a precise, specific bending point when the tear-off tab is opened to tear off the cover 3 from the container, and on the other hand, the slot 11 cannot be torn further through the container base 3 against its outer edge when the cover is removed.
- the slot 11, which partially delimits the tear tab 4 is formed in a lid base section 14, which slopes in a direction running away from the tear tab 4 against the indented area 1.2 of the lid base 3. Furthermore, a fold 15 running in a straight line is formed in the lid base 3 on the opposite side of the slot 11 from the groove 13. From this fold 15, a lid bottom section 16 (see in particular FIG. 3) runs against the base area 17 of the lid bottom section 14, which also contains the slot 11, and the indented area 12 of the lid bottom 3 is formed by these two sloping lid bottom sections 14 and 16. The outer side of the tear-away tab 4 is now aligned with the undeformed portion of the lid base 3 and the slot 11 is offset toward the inside of the lid.
- the tear-away tab 4 of this embodiment does not protrude above the lid base 3. Now that means it doesn't it is possible that the tear-off tab 4 can get caught somewhere in a transport container for the pre-cooked meals, for example an on-board kitchen, or in the on-board kitchen itself when it is reheated and can thus block the container. Nevertheless, the tear-away tab 4 is very easy to fold up, since the section of the sloping lid bottom section 14 above the slot 11 and obviously the edge of the slot 11 can easily be lifted up with the fingertip.
- the arrangement of the slot 11 shown has yet another function in that the contents of the container can be vented while it is being cooked, by allowing any steam generated to escape through the slot. It is therefore not possible for an overpressure to arise in the container while its contents are being heated.
- the lid 3 can be easily removed from the container 1 by the guest lifting the lid in such a way that it first disengages from the beaded edge 2 of the container 1 in the area of the tab 4 and then tears away continues in the direction of the diametrically or diagonally opposite corner region of the cover 3.

Abstract
Description
- Die Erfindung betriftt einen tiefgezogenen metallenen Behälterdeckel für einen Behälter mit einem Wulst- oder Rollrand, welcher Deckel einen Boden mit einer.Wegreisslasche und einen umlaufenden, vom Boden abstehenden Rand aufweist, der in einem Rollrand endet.
- Der Stand der Technik kennt keine tiefgezogene metallene Behälterdeckel zum Verschliessen eines mit einem Wulst- oder Rollrand ausgerüsteten Behälters. Zu diesem Zwecke bestimmte Behälterdeckel bedingten bisher zusätzlich zum Tiefziehen einen weiteren Herstellungs- schritt, um die eine Verbindung mit einem Behälter der beschriebenen Ausbildung erlaubende Verriegelungsorgane auszubilden.
- Ziel der Erfindung ist ein tiefgezogener metallener Behälterdeckel für einen Behälter mit einem Wulst-oder Rollrand zu zeigen, der ausschliesslich tiefgezogen ist.
- Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen Behälterdeckel für einen Behälter mit einem Wulst- oder Rollrand zu schaffen, welcher im umlaufenden Rand mindestens ein gegen das Deckelinnere verformter Wandabschnitt aufweist.
- Der durch die Erfindung erreichte Vorteil ist im wesentlichen darin zu sehen, dass ein tiefgezogener Deckel für einen Behälter mit einem Rollrand geschaffen ist, der sich einfach vom Behälter entfernen lässt und unabhängig vom Werkstoff des jeweiligen Behälters ist.
- Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnung näher erläutert.
- Fig. 1 eine Aufsicht auf einen tiefgezogenen metallenen Behälterdeckel,
- Fig. 2 einen Schnitt entlang der Linie II-II der Fig. 1,
- Fig. 3 einen Schnitt gleich demjenigen der Fig. 2 einer alternativen Ausführung, und
- Fig. 4 einen Schnitt entlang der Linie IV-IV der Fig. 1.
- Die in der Fig. 1 gezeigte Ausführung des Behälterdeckels ist zur Verwendung mit einem einen Wulst- oder Rollrand aufweisenden Behälter bestimmt, der seinerseits aus einem Metall oder beispielsweise Porzellan hergestellt ist. Solche Behälter gelangen beispielsweise im Luftverkehr zum Einsatz, wobei der Inhalt des Behälters in der Bordküche zum Verzehr erwärmt wird.
- Der Behälterdeckel ist ein beispielsweise aus Aluminium oder einer Aluminiumlegierung tiefgezogener Gegenstand.
- Der Deckel weist einen weitgehend ebenflächigen Boden 3 auf. Dieser Boden 3 ist einstückig mit einer Wegreisslasche 4 ausgebildet. Mittels dieser Wegreisslasche 4 lässt sich der Deckel vom Behälter wegreissen. Vom Boden 3 des Deckels steht der umlaufende Rand 5 ab, welcher in einem Rollrand 6 ended, wie dies aus den Figuren 2 und 3 zu entnehmen ist. Offensichtlich kann der Deckel 3 in der Aufsicht die unterschiedlichsten Formen gemäss dem zu verschliessenden Behälter aufweisen. Ebenfalls kann der Rand 5 unterschiedliche Querschnittsformen aufweisen. Die gezeigte Ausführungsform des Behälterdeckels ist entsprechend eines Behälters 1 mit einem Wulstrand 2 ausgebildet, wie in den Fig. 2 und 3 strichliniert angedeutet ist. Der Rand 5 weist mindestens einen, gegen das Deckelinnere hin verformten Wandabschnitt 7 auf, wie in den Fig. 2 und 3 angedeutet ist. Dieser verformte Wandabschnitt 7 verläuft in einer ersten Ausführung ununterbrochen entlang des umlaufenden Randes 5. Gemäss einer weiteren Ausführung sind mehrere voneinander getrennte verformte Wandabschnitte 7 vorhanden, welche punktförmige oder linienförmige Verformungen im Rand 5 sein können. In der Fig. 1 ist mit den mehreren Bezugsziffern 7 eine Ausführung dargestellt, die vier verformte,Wandabschnitte 7 enthält. Bei der Ausführung nach Fig. 3 ist jeder verformte Wandabschnitt durchbrochen, wobei die Durchbrechung ein in Deckelumfangsrichtung verlaufender Schlitz 10 ist. Damit ergeben sich dem jeweiligen Werkstoff entsprechend nachgiebige, gegen das Deckelinnere schiefwinklig hervorstehende Einrastlappen 8,9. Je nach gewünschter Ausführung kann nur ein solcher Einrastlappen, beispielsweise der in der Fig. mit 9 bezeichnete, oben gelegene Einrastlappen oder auch zwei solcher Einrastlappen 8,9 gemäss dem gezeichneten Ausführungsbeispiel vorhanden sein. Weil der Deckel und insbesondere sein Rand 5 nachgiebig ist, kann er beim Verschliessen des Behälters 1 ohne weiteres über dessen Wulst- oder Rollrand übergestülpt werden, wobei die verformten Wandabschnitte 7 bzw. die Einrastlappen unterhalb des Wulstes 2 zu liegen kommen und damit den Deckel fest mit dem Behälter 1 verbinden.
- Der Behälterdeckel ist mit einer Wegreisslasche 4 versehen, die einstückig mit dem Deckelboden 3 ausgebildet ist. Diese Wegreisslasche 4 ist durch einen nicht geradlinig verlaufenden-Schlitz 11, siehe hierzu auch Fig. 3, vom restlichen Deckelboden getrennt. Der Schlitz 11 kann aus geradlinigen, jeweils zwischen sich einen Winkel einschliessenden Abschnitten bestehen oder in der gezeigten Ausführung grundlinig, bespielsweise halbkreisförmig verlaufen. Der Deckelboden 3 weist nun beim Bereich der Wegreisslasche 4, der in den Fig. 1 und 3 mit der Bezugsziffer 12 angedeutet ist, einen eingebuchteten Bereich auf. Der Zweck dieser Ausbildung wird weiter unten erläutert. Die zwei Enden des etwa halbkreisförmig verlaufenden Schlitzes 11 sind mittels einer Rille 13 miteinander verbunden, welche Rille 13 aus ästhetischen Gründen eine geschlossene, entlang des Behälterrandes verlaufende Figur bildet. Der die zwei Enden des Schlitzes 11 verbindende Abschnitt dieser Rille 13 verläuft etwa geradlinig. Damit ergibt sich einerseits eine genaue bestimmte Biegestelle beim Aufklappen der Wegreisslasche zum Abreissen des Deckels 3 vom Behälter und andererseits ist ein Weiterreissen des Schlitzes 11 durch den Behälterboden 3 gegen dessen äusseren Rand beim Entfernen des Deckels nicht möglich.
- Wie insbesondere aus der Fig. 3 hervorgeht, ist der Schlitz 11,der die Wegreisslasche 4 teilweise umgrenzt in einem Deckelbodenabschnitt 14 ausgebildet, der in einer von der Wegreisslasche 4 weg verlaufenden Richtung gegen den eingebuchteten Bereich 1.2 des Deckelbodens 3 hin abfallend verläuft. Weiter ist bei der von der Rille 13 entgegengesetzten Seite des Schlitzes 11 ein-geradlinig verlaufender Falt 15 im Deckelboden 3 ausgebildet. Von diesem Falt 15 aus verläuft ein Deckelbodenabschnitt 16 (siehe insbesondere Fig. 3) gegen den Fusspunktbereich 17 des den Schlitz 11 enthaltenden, ebenfalls abfallenden Deckelbodenabschnittes 14, durch diese beiden abfallenden Deckelbodenabschnitte 14 und 16 ist der eingebuchtete Bereich 12 des Deckelbodens 3 gebildet. Damit fluchtet nun die Aussenseite der Wegreisslasche 4 mit dem nicht verformten Abschnitt des Deckelbodens 3 und der Schlitz 11 ist gegen das Deckelinnere hin versetzt angeordnet. Im Gegensatz zu früheren Wegreisslaschen steht die Wegreisslasche 4 dieser Ausführung nicht über den Deckelboden 3 hervor. Das bedeutet nun, dass es nicht möglich ist, dass sich die Wegreisslasche 4 in einem Transportbehälter für die vorgekochten Mahlzeiten, z.B. einer Bordküche,oder in der Bordküche selbst beim Wiedererwärmen irgendwo verfangen und damit den Behälter blokkieren kann. Trotzdem ist die Wegreisslasche 4 sehr einfach hochzuklappen, da der oberhalb des Schlitzes 11 verlaufende Abschnitt des abfallenden Deckelbodenabschnittes 14 und offensichtlich der Rand des Schlitzes 11 ohne weiteres mit der Fingerkuppe hochgehoben werden kann. Die gezeigte Anordnung des Schlitzes 11 weist noch eine weitere Funktion auf, indem eine Entlüftung des Behälterinhaltes während des Kochens desselben erfolgen kann, indem irgendwelcher erzeugter Dampf durch den Schlitz ausströmen kann. Damit ist ein Entstehen eines Ueberdruckes im Behälter während des Erhitzens seines Inhaltes nicht möglich.
- Ist die Lasche 4 und die Rille 13 hochgeklappt worden, lässt sich der Deckel 3 ohne weiteres vom Behälter 1 abziehen, indem der Gast den Deckel derart abhebt, dass er zuerst beim Bereich der Lasche 4 vom Wulstrand 2 des Behälters 1 ausrastet und darauf das Wegreissen in Richtung zum diametral, bzw. diagonal entgegengesetzten Eckbereich des Deckels 3 fortführt.
