Abstract

The quick brewing coffee filter comprises a cylindrical beaker (1) conical at its lower end and perforated (7) throughout its jacket and base (8). Two or more clip holders (4) which project downwardly inclined from the cylinder are located at the upper end. When the lid (2) closing the top of the cylinder is pressed down the clips hold down both the filter paper (5) which is stretched over the cylinder and the lid itself. The lid is wide enough so that it can be set on the edge of the coffee pot and on its underneath has an annular edge (3) whose diameter is so large that it can be inverted over the cylinder edge. The lid is provided in the middle with a hole (9) which guides the rod (10) of a hollow piston which is to be moved up and down in the cylinder by hand. This piston acts as a float and forces the water through the coffee, the cylinder openings and the filter paper and once pressed down then floats back up.

Patentbeschreibung Die Erfindung hat den Zweck,das Zubereiten von Kaffeegetränkenbedeutend zu beschleunigen, zu vereinfachen und den Kaffee besser ausæunutzen. Patent description The invention has the purpose of preparing Coffee beverages are important to speed up, simplify and make coffee better take advantage of.

Dies ftrd dadurch erreicht,dass der Filter aus einem becherartigen Zylinder besteht,der an seinem unteren F,nde konisch verlauft und dessen Ii2ntel und Boden von Löchern durchbrochen ist.Am oberen ~ende des Zylinders befinden sich zwei oder mehrere vom Zylinder schräg nach unten abstehende klammerartige Halter welche so ausgebildet sind,daß sie beim Niederdrücken eines den Zylinder nach oben ver= schließenden Deckels sowohl das über den Zylinder gestreifte Filter papier als auch den Deckel festhalten.Der Deckel ist so breit,daß er auf dem Rand der Kaffeekanne aufgesetzt werden kann urid hat an seiner Unterseite einen ringförmigen Rand dessen Durchmesser so groß ist,daß er über den Zylinderrand gestülpt werden kann und so ausge= bildet ist,daß er beim Niederdrücken vermittels des klammerartigen Halters das Filterpapier sowie den Deckel in seiner Lage festhält.This is achieved by making the filter from a cup-like Cylinder exists, which is conical at its lower edge and its i2ntel and bottom is pierced by holes. At the top of the cylinder are two or more clamp-like holders protruding obliquely downward from the cylinder which are designed so that when one is depressed the cylinder upwards closing the lid and put the filter paper over the cylinder and hold the lid tight. The lid is so wide that it rests on the edge of the coffee pot can be put on urid has an annular edge on its underside The diameter is so large that it can be slipped over the edge of the cylinder and so on designed is that it is when pressed down by means of the clamp-like holder holds the filter paper and the lid in place.

In der Mitte des Deckels befindet sich ein Loch das dazu dient,die Stange eines sich im Zylinder von Hand auf und nieder zu bewegenden Hohlkolbens zu führen.Der Kolben hat den Zweck,das Kaffeewasser durch den Kaffee,die Zylinderöffnungen und das Filterpapier zu pressen.In the middle of the lid there is a hole that is used for the Rod of a hollow piston that can be moved up and down by hand in the cylinder The purpose of the piston is to drive the coffee water through the coffee, the cylinder openings and press the filter paper.

Durch die Eigenschaft des Hohlkolbens ist es nicht mehr erforderlich, diesen nach dem Herrunterdrüeken wieder hochzuziehen, da dieser durch seine schwimmerartige Ausbildung dies automatisch tut.Due to the property of the hollow piston, it is no longer necessary to pull it up again after being suppressed, as this is due to its float-like shape Training does this automatically.

Der wesentliche Vorteil gegenüber dem bisher Bekannten besteht darin, daß der Filter nach dem Aufsetzen auf die Kaffeekanne oder sonstigen Behälter sofort in das kochende Wasser eintaucht und das Kaffeege= tränk nach ein oder mehrmaligem Niederdrücken serviert werden kann.The main advantage over the previously known is that that the filter immediately after being placed on the coffee pot or other container immerse in the boiling water and drink the coffee after one or more times Depression can be served.

Diese Anordnung ermöglicht ein wesentlich schnelleres Bereiten von Xaffeegetränken,ein besseres Ausnutzen des gemahlenen Kaffees und ver= hindert das bei den bisher gebräuchlichen Filtern während des Nach= füllens unumgängliche Abkühlen.This arrangement enables a much faster preparation of Xaffe beverages, a better use of the ground coffee and prevents that In the case of the filters used up to now, cooling down during refilling is unavoidable.
