Description

Die Erfindung betrifft einen Brennereinsatz, insbesondere für kerzenförmige Leuchtkörper, bestehend aus einer mit flüssigem Brennstoff füllbaren, im wesentlichen zylindrischen Dose mit einem an der Oberseite herausragenden Docht, der in einem zentrisch in die Oberseite eingesetzten Führungsröhrchen geführt ist und dessen unteres Ende mindestens bis zum Boden der Dose reicht, wobei die Oberseite der Dose als abschraubbarer Deckel ausgebildet ist, der mit einem an seinem unteren Bereich vorgesehenen Außengewinde in ein am Rand der zylindrischen Dose angeordnetes Innengewinde eingeschraubt und mit einem zwischen einem Dichtrand am Deckel und einem Dichtrand an der Dose eingelegten Dichtring abgedichtet ist und der mit einem zentrischen Durchlaß versehen ist, in welchen das Führungsröhrchen mit dem Docht eingesetzt ist.The invention relates to a burner insert, in particular for candle-shaped luminous elements, consisting of an essentially cylindrical can, which can be filled with liquid fuel, with a wick protruding on the top, which is guided in a guide tube inserted centrally into the top, and the lower end of which at least to the bottom the can is sufficient, the top of the can being designed as a screw-on cover, which is screwed with an external thread provided at its lower area into an internal thread arranged at the edge of the cylindrical can and with a sealing ring inserted between a sealing edge on the cover and a sealing edge on the can is sealed and which is provided with a central passage in which the guide tube with the wick is inserted.

Ein Brennereinsatz dieser Art ist bekannt aus US-A-4 781 577. Das Führungsröhrchen für den Docht ist in den abschraubbaren Deckel so eingeschraubt, daß sein oberer Rand über den oberen Rand des Deckels vorsteht. Die bei diesem bekannten Brennereinsatz oberhalb des Deckelrandes brennende Flamme ist sehr seitenwindempfindlich und brennt relativ unruhig.A burner insert of this type is known from US-A-4 781 577. The guide tube for the wick is screwed into the unscrewable cover in such a way that its upper edge projects beyond the upper edge of the cover. The flame burning above the edge of the lid in this known burner insert is very sensitive to side winds and burns relatively uneasily.

Der Erfindung liegt die Aufgabe zugrunde, einen Brennereinsatz der eingangs beschriebenen Art so zu verbessern, daß seine Flamme auch unter ungünstigen Bedingungen ruhig und gleichmäßig brennt.The invention has for its object to improve a burner insert of the type described above so that its flame burns quietly and evenly under unfavorable conditions.

Diese Aufgabe wird, ausgehend von einem Brennereinsatz gemäß dem Oberbegriff des Anspruchs 1, erfindungsgemäß dadurch gelöst, daß der Deckel eine vertiefte Oberseite aufweist und in Nähe des oberen Randes mit mehreren auf dem Umfang verteilten Luftlöchern versehen ist.Starting from a burner insert according to the preamble of claim 1, this object is achieved according to the invention in that the cover has a recessed upper side and is provided in the vicinity of the upper edge with a plurality of air holes distributed over the circumference.

Die unterhalb der Flamme allseitig zufließende Verbrennungsluft bewirkt eine Stabilisierung der Flamme und damit auch ein ruhiges und gleichmäßiges Abbrennen.The combustion air flowing in from all sides below the flame stabilizes the flame and thus also calms down and burns off evenly.

Der erfindungsgemäße Brennereinsatz ist mühelos durch Abschrauben des Deckels zu öffnen, kann dann mit flüssigem Brennstoff aus einem Vorratsbehälter aufgefüllt und anschließend wieder dicht verschlossen werden. Falls erforderlich, kann dabei auch der Docht erneuert werden.The burner insert according to the invention can be opened effortlessly by unscrewing the lid, can then be filled with liquid fuel from a storage container and then sealed again. If necessary, the wick can also be replaced.

Weitere Merkmale der Erfindung sind den Patentansprüchen 2 bis 5 zu entnehmen.Further features of the invention can be found in claims 2 to 5.

In der folgenden Beschreibung wird ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnung näher erläutert. Die Zeichnung zeigt einen Längsschnitt durch einen erfindungsgemäßen Brennereinsatz.In the following description, an embodiment of the invention is explained in more detail with reference to the drawing. The drawing shows a longitudinal section through a burner insert according to the invention.

In der Zeichnung besteht der Brennereinsatz aus einer im wesentlichen zylindrischen Dose 1 mit einem abschraubbaren Deckel 2. Auf der Oberseite des Deckels 2 ragt ein Docht 3 heraus, der in einem Führungsröhrchen 4 geführt ist, welches in einen zentrischen Durchlaß im Deckel 2 eingesetzt ist. Der Durchlaß ist so gestaltet, daß ein Belüftungskanal zwischen Führungsröhrchen 4 und Durch laß freibleibt. An seinem unteren Bereich ist der Deckel 2 min einem Außengewinde 6 versehen. Das Außengewinde 6 ist in ein Innengewinde 7 eines Gewinderinges 8 eingeschraubt, der am Oberen Rand der im Fließpreßverfahren aus Metall hergestellten Dose 1 eingerollt ist. Zur Abdichtung ist ein Dichtring 9 zwischen einem Dichtrand 10 am Deckel 2 und einem Dichtrand 11 an der Dose 1 eingelegt. Nach dem Einfüllen des flüssigen Brennstoffes wird bei dieser Anordnung durch festes Aufschrauben des Deckels die gleiche betriebssichere Dichtheit erreicht, wie bei den bekannten, nicht zu öffnenden Dosen.In the drawing, the burner insert consists of an essentially cylindrical can 1 with a screw-off lid 2. On the top of the lid 2, a wick 3 protrudes, which is guided in a guide tube 4, which is inserted into a central passage in the lid 2. The passage is designed so that a ventilation channel between the guide tube 4 and let through remains free. At its lower area, the cover is provided with an external thread 6 for 2 minutes. The external thread 6 is screwed into an internal thread 7 of a threaded ring 8 which is rolled up at the upper edge of the can 1 made of metal by the extrusion process. For sealing, a sealing ring 9 is inserted between a sealing edge 10 on the cover 2 and a sealing edge 11 on the can 1. After filling in the liquid fuel, the same reliable tightness is achieved in this arrangement by firmly screwing on the lid as in the known, non-opening cans.

Um eine ruhig und gleichmäßig brennende Flamme zu erreichen und dem kerzenförmigen Leuchtkörper ein möglichst einer natürlich abbrennenden Kerze angenähertes Aussehen zu geben, weist der Deckel 2 bes Brennereinsatzes eine vertiefte Oberseite 12 auf und ist in Nähe seines oberen Randes mit mehreren, auf dem Umfang verteilten Luftlöchern 13 versehen, die vorteilhaft vom Umfang des Deckels zu dessen Mitte hin schräg nach oben gerichtet sind. Außerdem ist es vorteilhaft, wenn das Führungsröhrchen 4 für den Docht 3 etwas über den oberen Rand des Deckels 2 vorsteht. Ein unbehinderter aber zugluftarmer Luftzutritt zur Flamme ist bei dieser Anordnung gesichert und die gut belüftete Ausnehmung um die Flamme herum verhindert ein unerwünschtes Aufheizen des Deckels. Die Vertiefung 12, deren Wandung reflektierend sein kann, ermöglicht zudem eine freie Abstrahlung des Lichtes, das durch die Luftlöcher 13 auch zu dem oberen Rand des kerzenartigen Hohlkörpers, in den der Brennereinsatz einzusetzen ist, durchschimmern kann.In order to achieve a steady and evenly burning flame and to give the candle-shaped luminous body an appearance that approximates that of a candle that burns as naturally as possible, the cover 2 of the burner insert has a recessed upper side 12 and is near its upper edge with a plurality of air holes distributed around the circumference 13 provided, which are advantageously directed obliquely upwards from the circumference of the cover to the center thereof. It is also advantageous if the guide tube 4 for the wick 3 protrudes slightly above the upper edge of the lid 2. An unobstructed but low-draft air access to the flame is ensured with this arrangement and the well-ventilated recess around the flame prevents the lid from heating up undesirably. The recess 12, the wall of which can be reflective, also enables a free emission of the light, which can also shine through the air holes 13 to the upper edge of the candle-like hollow body in which the burner insert is to be inserted.

In einer bevorzugten Ausführungsform der Erfindung weist die Oberseite 12 des Deckels 2 eine konkave Krümmung auf und der zentrische Durch laß für das Führungsröhrchen 4 ist von einem nach oben stehenden Bund 14 umgeben, der unterhalb des Niveaus der Luftlöcher 13 endet, und das Führungsröhrchen 4 weist nach oben eine konische Erweiterung 15 auf, die das Einschieben in den Bund 14 begrenzt und deren Höhe derart ausgelegt ist, daß der Docht 3 etwas oberhalb des oberen Randes des Deckels 2 freigegeben wird. Bei dieser Ausführung ist das Einsetzen bzw. das Auswechseln des Dochtes besonders einfach und es wird eine betriebssichere Halterung des Dochtes mit Flammenbildung in der gewünschten Höhe erreicht.In a preferred embodiment of the invention, the top 12 of the lid 2 has a concave curvature and the central passage for the guide tube 4 is surrounded by an upstanding collar 14 which ends below the level of the air holes 13 and the guide tube 4 upwards a conical extension 15, which limits the insertion into the collar 14 and the height of which is designed such that the wick 3 is released somewhat above the upper edge of the cover 2. In this embodiment, the insertion or replacement of the wick is particularly simple and the wick is held securely with flames at the desired height.

Um das Auf- und Abschrauben des Deckels 2 zu erleichtern, ist sein Umfang mit einer Rändelung 16 versehen.In order to facilitate screwing and unscrewing the cover 2, its circumference is provided with a knurling 16.

Der Brennereinsatz gemäß der Erfindung ist nicht nur für kerzenförmige Leuchtkörper geeignet, sondern kann auch mit Vorteil für Windlichter und Party-Beleuchtungen für Garten und Terrasse verwendet werden. Dabei können auch mehrere Brennereinsätze in mehrflammigen Leuchtkörpern zusammengestellt werden. Durch verschiedene Zusätze zu dem eingefüllten flüssigen Brennstoff können verschiedenfarbige Flammen erreicht werden.The burner insert according to the invention is not only suitable for candle-shaped lamps, but can also be used advantageously for lanterns and party lights for the garden and terrace. Several burner inserts can also be put together in multi-lamp filaments. Flames of different colors can be achieved by adding different additives to the liquid fuel.

Der aufschraubbare Deckel 2 kann auf unterschiedlich hohe Dosen aufgeschraubt werden, so daß der Brennereinsatz dem jeweiligen Verwendungszweck angepaßt werden kann.The screw-on lid 2 can be screwed onto cans of different heights, so that the burner insert can be adapted to the respective purpose.
