Description

Spitzfilter mit von oben nach unten verlaufenden Rippen auf der Innenwandung, insbesondere zur Herstellung von Aufbrühgetränken -Die Erfindung betrifft ein Spitzfilter, insbesondere zur Herstellung von Aufbrühgetränken, dessen Innenwandung mit von oben nach unten verlaufenden Rippen bzw. Rillen versehen ist. Das Neue besteht darin, daß das kegelförmige Filtergefäß an seiner Spitze geschlossen ist und daß in verschiedenem Abstand von der Spitze an den Enden der Rillen Abflußlöcher angebracht sind, die in auf der Außenwand unterhalb des Aufsetzringes angebrachte Rillen münden.Pointed filter with ribs on the inner wall running from top to bottom, especially for the production of brewed beverages -The invention relates to a pointed filter, in particular for the production of brewed beverages, the inner wall of which with from above downwardly extending ribs or grooves is provided. The new thing is that the conical filter vessel is closed at its tip and that in different Distance from the tip at the ends of the grooves drain holes are attached, the open into grooves made on the outer wall below the attachment ring.

Es sind zwar bereits Spitzfilter bekanntgeworden, bei denen sowohl die Innenwandung als auch die Außenwandung mit von oben nach unten verlaufenden Rippen versehen ist, jedoch haben hier die Rippen auf der Außenwand den Zweck, das Austreten von Luft beim Aufsetzen des Trichters auf Flaschen zu ermöglichen, während sie beim Erfindungsgegenstand den Zweck haben, die durch die in der Seitenwandung vorgesehenen Löcher austretende Flüssigkeit in einem zusammenhängenden Strahl zu sammeln, um auf diese Weise einen Sog zu erzielen, der sich über die zugehörige Rille erstreckt und eine Beschleunigung der Filterung bewirkt.Pointed filters have already become known in which both the inner wall as well as the outer wall with running from top to bottom Ribs is provided, but here the ribs on the outer wall have the purpose of Allow air to escape when placing the funnel on bottles while they have the purpose of the subject matter of the invention by the in the side wall provided holes to the escaping liquid in a continuous stream collect in order to create a suction that spreads over the associated Groove extends and causes an acceleration of the filtering.

Weiterhin ist es bereits bekannt, die Wandung von Spitzfiltern mit Löchern zu versehen, jedoch nur zu dem Zweck, Hohlräume unter dem an die 'Wand anliegenden Filterpapiier zu erhalten, um auf diese Weise die Filtergeschwindigkeit zu erhöhen. Beim Erfindungsgegenstand dagegen haben die an den Enden der Rillen angebrachten Abflußöfnungen die Wirkung, daß sie die Spitze der in das Gefäß eingesetzten Filtertüte entlasten, die bei den bisher bekannten Spitzfiltern beim Eingießen kochenden Wassers leicht reißt, weil sich ein durch das Abflußrohr bedingter großer Hohlraum darunter befindet. Ein solches Einreißen der Filtertüte kann beim Erfindungsgegenstand nicht mehr vorkommen, da die Spitze auf der vollen Wand des Trichters aufliegt.Furthermore, it is already known to use the wall of pointed filters To provide holes, but only for the purpose of creating cavities under the adjacent wall Obtain filter paper in order to increase the filter speed in this way. In the subject matter of the invention, however, have those attached to the ends of the grooves Drainage openings have the effect that they are the tip of the filter bag inserted into the vessel Relieve the strain on the previously known pointed filters when pouring boiling water tears easily because there is a large cavity underneath caused by the drainpipe is located. The subject of the invention cannot tear the filter bag in this way occur more because the tip rests on the full wall of the funnel.

In. der Zeichnung ist ein Ausführungsbeispiel. der Erfindung dargestellt. Es zeigen: Abb. i einen senkrechten Schnitt durch ein Spitzfilter mit eingesetzter Filtertüte und Abb.2 die Draufsicht auf das Filtergefäß nach Abb. i.In. the drawing is an exemplary embodiment. of the invention shown. They show: Fig. I a vertical section through a pointed filter with an inserted Filter bag and Fig.2 the top view of the filter vessel according to Fig. I.

Das Spitzfiltergefäß a ist mit von oben nach unten verlaufenden Rippen b versehen, die verschieden lang sind, wobei jedoch keine Rippe ganz bis zur Spitze des Gefäßes reicht, damit die Spitze der eingesetzten Filtertüte c ganz auf der Innenwandung des Gefäßes aufliegt und nicht reißen kann. Am Ende der durch die Rippen b gebildeten Rillen d sind Abflußöffnungen f angebracht, und zwar in verschieden großem Abstand von der Spitze, wobei die öffnungen f nach der Spitze zu immer kleiner werden, damit sie keine gefährlichen Hohlräume für die Filtertüte c bilden können und sich das Filtrat gleichmäßig auf die verschiedenen öffnungen verteilt.The pointed filter vessel a has ribs running from top to bottom b, which are of different lengths, but with no rib all the way to the tip of the receptacle is sufficient for the tip of the inserted filter bag c to lie completely on the Inner wall of the vessel rests on and cannot tear. At the end of by the ribs b formed grooves d are drainage openings f attached, namely in different large distance from the tip, the openings f becoming smaller and smaller towards the tip so that they cannot form dangerous cavities for the filter bag c and the filtrate is evenly distributed over the various openings.

Auf der Außenwand des Filtergefäßes a sind unterhalb des Aufsetzringes g gleichfalls von oben nach unten verlaufende Rippen h derart angebracht, daß die Abflußöffnungen f in die durch diese Rippen h gebildeten Rillen münden, so daß das gesamte aus den öffnungen f austretende Filtrat durch die Rillen. zur Spitze und von hier in einem zusammenhängenden Strahl abfließen muß.On the outer wall of the filter vessel a are below the attachment ring g ribs h also extending from top to bottom are attached in such a way that the Drainage openings f open into the grooves formed by these ribs h, so that the all of the filtrate emerging from the openings f through the grooves. to the top and must flow from here in a continuous stream.
