Device for preparing filtered brewed beverages

The invention relates to an assemblable device for preparing filtered brewed beverages, in particular for electrically operated coffee machines, consisting of a combination of jug, jug lid and one funnel-shaped, the paper filter insert receiving on its inner side walls provided with longitudinal ribs Filter vessel.

For the preparation of filtered brewed beverages such as coffee, tea or the like. Today, funnel-shaped beverages are usually used Filter vessels, in which exchangeable filter paper in the shape of a bag can be inserted, because of the great handiness and the achievable quality of the brewed beverage is used. For this purpose are funnel-shaped on a jug attachable filter vessels known which have a circumferential flange on the outside in the area of their lower end, which rests on the edge of the jug during the filtering process. A funnel-shaped one is also known Filtergeiäß, which in its upper area by an am The upper edge of the attached cylindrical jacket that can be placed on the edge of the jug is surrounded. With such Filter vessel-jug combinations, the jug lid must be kept separate from the jug for as long as the filter vessel is placed on the jug. Another disadvantage of such a combination is that in the case of

Overflow of the filter vessel during the filtering process the overflowing liquid contaminates the jug base.

It has now been found that these deficiencies are eliminated if, according to the invention, the external shape of the filter vessel Has the shape of a truncated cone and its inner shape consists in a known manner from a funnel, which from an oval to, in the borderline case, linear filter base with a central drainage opening starts and merges into a circular shape via a correspondingly oval cross-section. The lower end area of the filter vessel is correspondingly frustoconical designed with a central drainage opening in the middle of the jug lid, which is surrounded by a concentric circumferential channel, can be used. In this combination according to the invention, can the jug lid remain in the jug opening even when the filter vessel is in place. In the between the support edge the jug lid and the groove surrounding the recess can be overflowing and on the outer wall of the funnel vessel Collect any liquid that runs down and drain through the opening made in it.

In order to avoid the risk of overflowing, the opening angle of the funnel of the filter vessel is preferred 10 to 25 °, in particular 15 to 20 °, in its upper end area greater than the opening angle of the Funnel in the rest of the area.

So that when the filter vessel overflows, the liquid running down on the outer wall of the filter vessel is removed film cannot detach from it, it is advisable to fit the • filter vessel with a unit that forms a unit with it cylindrical jacket, the lower end of which in

730607 «and β. 78

stands up in the channel between the support edge and the recess of the jug lid.

In the drawing is an embodiment of the invention, essentially shown as a half-section along the major axis of the filter vessel bottom.

The outside frustoconical shaped and from one cylindrical jacket 1 surrounded filter vessel 2, whose with an outflow opening 3 provided with dash-dotted lines, because the funnel 4 is offset by 90 °, the upper end region has an opening angle I of 80 ° and the rest Area has an opening angle II of 65 °, is with its lower end in a correspondingly frustoconical centrally arranged with a central outflow opening / provided recess 5 used, wherein the Jacket 1 in the between the support edge 6 of the can lid inserted into the can 7 with the help of the centering edge 8 9 and the recess 5 concentrically circumferential channel 11 provided with an outflow opening 10 stands up.
