Abstract

Lid (1) for sealing onto a preferably dish-shaped vessel (6) provided with an edge flange (7), the lid being provided at least at one point on its circumference with three cutting lines (3,4,5), one of which in each case is introduced on both sides of the sealing seam of the underside facing the vessel (6) and the third cutting line is introduced from the topside at a small distance from the inner lower cutting line, the lid (1) consisting of a material which can be split between its two surfaces and parallel thereto. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Deckel zum Aufsiegeln auf ein mit einem Randflansch versehenes, vorzugsweise schalenförmiges Gefäß.The invention relates to a lid for sealing onto a preferably bowl-shaped vessel provided with an edge flange.

Werden in einem derartigen Gefäß verpackte Lebensmittel erwärmt, so ist es zweckmäßig die Lebensmittel im Gefäß zu belassen und den Deckel verschlossen zu halten, da sonst der Inhalt während des Erhitzens herausspritzt. Beim Erhitzen entsteht jedoch Wasserdampf, der im Extremfall das Gefäß zum Zerplatzen bringt.If food packaged in such a container is heated, it is advisable to leave the food in the container and to keep the lid closed, otherwise the contents will spurt out during heating. When heated, however, water vapor is generated, which in extreme cases causes the vessel to burst.

Der Erfindung liegt die Aufgabe zugrunde, einen Deckel der genannten Art so auszugestalten, daß die im Gefäß verpackten Lebensmittel im geschlossenen Zustand erhitzt werden können und trotzdem keine Gefahr für das Gefäß bzw. den Deckel durch den entstehenden Wasserdampf besteht.The invention has for its object to design a lid of the type mentioned so that the food packaged in the container can be heated in the closed state and still there is no danger to the container or the lid by the water vapor generated.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Deckel wenigstens an einer Stelle seines Umfanges mit drei Schnittlinien versehen ist, von denen je eine beiderseits der Siegelnaht von der dem Gefäß zugekehrten Unterseite und die dritte in geringem Abstand von der inneren unteren von der Oberseite her eingbracht ist, und daß der Deckel aus einem zwischen seinen beiden Oberflächen und parallel zu diesen spaltbaren Material besteht.This object is achieved in that the lid is provided at least at one point on its circumference with three cutting lines, one of which introduces both sides of the sealing seam from the bottom facing the vessel and the third at a short distance from the inner bottom from the top and that the lid is off one between its two surfaces and parallel to these fissile material.

Dadurch ist es möglich, den durch diese drei Schnittlinien begrenzten Abschnitt des Deckels vor dem Erhitzen abzuspalten und damit den entstehenden Wasserdampf entweichen zu lassen. Ein Herausspritzen von Teilen des Lebensmittels ist dabei nicht zu befürchten, da der dem Füllgut zugewandte untere Teil des Deckelmaterials nicht herausgelöst wird.This makes it possible to split off the section of the lid delimited by these three cutting lines before heating and thus to let the water vapor escape. Splashing out of parts of the food is not to be feared since the lower part of the lid material facing the filling material is not detached.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Schnittlinien jeweils wenigstens bis zur Mitte des Deckelmaterials reichen.It is also very advantageous if, according to the invention, the cutting lines each extend at least to the middle of the lid material.

Damit wird ein sicheres Aufspalten des Deckelmaterials gewährleistet.This ensures safe splitting of the lid material.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, daß der Deckel aus Karton hergestellt ist und wenigstens im Bereich der herzustellenden Siegelnaht auf seiner Unterseite siegelfähig beschichtet ist.Another advantageous embodiment of the invention is that the lid is made of cardboard and is coated so that it can be sealed on its underside, at least in the area of the sealing seam to be produced.

Kartonmaterial läßt sich verhältnismäßig leicht spalten, so daß das Öffnen des Dampf-Ventils leicht durchzuführen ist; durch die siegelfähige Beschichtung wird aber gleichzeitig ein sicherer Verschluß des Deckels mit dem Gefäß gewährleistet.Cardboard material can be split relatively easily, so that the steam valve can be opened easily; however, the sealable coating ensures that the lid is securely closed with the vessel.

Ebenfalls sehr vorteilhaft ist es, wenn gemäß der Erfindung im Bereich der drei Schnittlinien ein Lappen am Deckel angeformt ist, welcher über den Rand des Gefäßes hinausragt.It is also very advantageous if, according to the invention, a tab is formed on the lid in the region of the three cutting lines, which tab projects beyond the edge of the vessel.

Dieser überstehende Lappen kann leicht erfaßt und damit das Aufspalten des Deckels besonders einfach bewerkstelligt werden.This protruding flap can be easily grasped and the splitting of the lid can thus be accomplished particularly easily.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

Mit 1 ist in Fig.1 ein ebener Deckel bezeichnet, der zum Aufsiegeln auf einen mit Randflansch versehenen Behälter bestimmt ist. An diesen Deckel 1 ist ein Lappen 2 angeformt, an dessen innerer Begrenzungslinie von der Unterseite her eine Schnittlinie 3 vorgesehen ist. Darüber hinaus weist der Deckel 1 eine ebenfalls von unten her eingebrachte mit Abstand vom äußeren Rand umlaufende Schnittlinie 4 auf. Eine weitere Schnittlinie 5 verläuft über die mit dem Lappen versehene Ecke des Deckels, wobei diese dritte Schnittlinie von oben her in den Deckel eingebracht ist.1 in FIG. 1 denotes a flat lid which is intended for sealing onto a container provided with an edge flange. A flap 2 is formed on this cover 1, on the inner boundary line of which a cutting line 3 is provided from the underside. In addition, the cover 1 also has a cutting line 4, which is also introduced from below and is at a distance from the outer edge. A further cutting line 5 runs over the corner of the lid provided with the rag, this third cutting line being introduced into the lid from above.

In den Figuren 2 und 3 ist der Deckel 1 auf ein schalenförmiges Gefäß 6 aufgesiegelt, das einen Randflansch 7 aufweist, welcher der Herstellung der Siegelnaht zwischen Deckel und Gefäß dient. Der Lappen 2 ragt über diesen Randflansch 7 hinweg und dient als Handhabe zum Öffnen der aus Gefäß und Deckel gebildeten Verpackung. Alle drei Schnittlinien 3, 4 und 5 ragen etwas weiter als zur Mitte der Materialdicke in den Deckel 1 hinein, so daß beim Aufreißen mit Hilfe des Lappens 2 eine sichere Materialspaltung etwa in der Mitte des Deckelmaterials stattfindet.In FIGS. 2 and 3, the lid 1 is sealed onto a bowl-shaped vessel 6 which has an edge flange 7 which serves to produce the sealed seam between the lid and the vessel. The tab 2 protrudes over this edge flange 7 and serves as a handle for opening the packaging formed from container and lid. All three cutting lines 3, 4 and 5 protrude slightly further than the middle of the material thickness into the lid 1, so that when tearing open with the aid of the flap 2 a secure material splitting takes place approximately in the middle of the lid material.

Ein so aufgespalteter Deckel 1 ist in den Figuren 4 und 5 dargestellt. Der vollständige Lappen sowie die obere Hälfte des durch die innerste Schnittlinie 5 begrenzten Deckelabschnittes sind entfernt, wodurch ein Teilstück der Schnittlinie 4 freigelegt ist, so daß im Innern des Gefäßes entstehender Dampf entweichen kann.A lid 1 thus split is shown in FIGS. 4 and 5. The complete rag and the upper half of the lid section delimited by the innermost cutting line 5 are removed, whereby a section of the cutting line 4 is exposed, so that steam arising in the interior of the vessel can escape.

Zum weiteren Öffnen kann ein Mittelabschnitt des Deckels 1 entlang der Schnittlinie 4 herausgetrennt werden, wobei die Siegelnaht zwischen Deckel und Randflansch bestehen bleibt. Als Material für den Deckel hat sich insbesondere Karton bewährt, der wenigstens im Bereich der Siegelnaht mit einem siegelfähigen Kunststoff beschichtet ist. Für besondere Füllgüter ist es jedoch zweckmäßig, die gesamte Innenseite des Deckels mit einem solchen Kunststoff zu beschichten.To open it further, a central section of the cover 1 can be cut out along the section line 4, the sealing seam between the cover and the edge flange remaining. Cardboard, which is coated with a sealable plastic at least in the area of the sealing seam, has proven particularly useful as the material for the lid. For special filling goods, however, it is advisable to coat the entire inside of the lid with such a plastic.
