COFFEE FILTER HOLDER

Abstract

A coffee filter holder configured to be placed on a coffee pot and to receive a filtering arrangement that is at least partially filled with coffee powder, the coffee filter holder including a conical receiver for the filtering arrangement, the conical receiver including a base side pass through opening and a base plate configured to support the coffee filter holder on the coffee pot; and a valve arrangement that is arranged below the base plate wherein the valve arrangement is actuated by a weight of the coffee filter holder when the coffee filter holder is placed on the coffee pot.

Claims

1. A coffee filter holder configured to be placed on a coffee pot and to receive a filtering arrangement that is at least partially filled with coffee powder, the coffee filter holder comprising: a conical receiver for the filtering arrangement, the conical receiver including a base side pass through opening and a base plate configured to support the coffee filter holder on the coffee pot; and a valve arrangement that is arranged below the base plate wherein the valve arrangement is actuated by a weight of the coffee filter holder when the coffee filter holder is placed on the coffee pot.

2. The coffee filter holder according to claim 1, wherein the valve arrangement includes a closure element that is arranged below the pass through opening and a radially extending pivot arm that is connected with the closure element and spring loaded in a closing direction.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Further advantages of the invention can be derived from the subsequent description of an embodiment with reference to drawing figures, wherein:

[0010] FIG. 1 illustrates a side view of a coffee filter holder;

[0011] FIG. 2 illustrates sectional view of the coffee filter illustrated in FIG. 1; and

[0012] FIG. 3 illustrates a sectional view through a coffee pot with the coffee filter holder according to FIG. 2.

DETAILED DESCRIPTION OF THE INVENTION

[0013] In the drawing figures, a coffee filter holder is overall designated with the reference numeral 10.

[0014] FIG. 1 illustrates a coffee filter holder 10 that includes a funnel 11 for receiving the non-illustrated coffee filter. The funnel 11 has a free form transition shape wherein the upper opening is circular and the base portion is oval. In the operating condition a non-illustrated filter arrangement is arranged in the funnel 11 of the coffee filter holder 10 wherein the filter arrangement is configured as a paper filter or as a permanent filter configured as a reusable stainless steel or synthetic material filter.

[0015] A handle 12 is arranged at the outer circumference of the funnel element 11. In the base portion the funnel 11 is provided with a pass through opening 13 (c.f. FIG. 2). Below or laterally from the base portion of the filter 11 a circular plate 14 with a tubular extension 15 is arranged. Below the plate 14 that is used for supporting the coffee filter holder on a coffee pot 16 (FIG. 3) a rocker arm 17 is arranged that extends in a radial outward direction from the portion below the pass through opening 13 through a window opening (F) wherein the rocker arm is pivotally supported at the coffee filter holder 10 between the portion of the pass through opening 13 and a free end portion 20. The rocker arm 17 includes a silicone seal element 18 below the pass through opening 13 and a compression spring 21 is arranged between the pivot lever 17 and a bottom surface 19 of the plate 14 between the non-illustrated joint and the free end 20 of the pivot lever 17 wherein the compression spring provides that the pass through opening 13 is closed drip tight by the silicone seal 18 in a position where the coffee filter holder is not placed on a coffee pot 16 (c.f. FIG. 2). It is appreciated that that the seal 18 can also be made from other seal materials.

[0016] Only when the coffee filter holder is placed on the coffee pot 16 according to FIG. 3 the pivot lever 17 moves into the impact portion of the upper edge portion of the coffee pot 16 wherein the weight of the coffee filter holder 10 moves the pivot lever 17 counter clock wise upward until the pivot lever contacts the bottom side of the plate 14. In order to better support the pivot lever 17 the free end portion 20 is furthermore provided with a protrusion 22 which reaches through a pass through opening 23 in the plate in an open condition of the valve arrangement (c.f. FIG. 3).

[0017] Using the illustrated coffee filter holder 10 it is advantageously possible to fill individual cups, beakers or also other coffee pots one after the other without contaminating the environment when moving the coffee filter holder 10 onto a new container that is to be filled.
