The present disclosure relates to a filter system for preparing beverages based on a beverage base, such as for example coffee powder, soup powder, or tea.
It is known from the prior art to insert either suitable tea, soup, or coffee bags or filter-/straining containers (e.g. tea filters, tea strainers, soup filters, etc.) into containers, wherein after the infusion of a warm/hot liquid (e.g. water or milk) into the beverage base, the flavoring and active ingredients can pass into the liquid.
Especially in the preparation of tea, the correct steep time is absolutely essential, since otherwise the tea loses its stimulating effect and loses its aroma and taste. Therefore, in principle, after an individually defined time, the filter or the strainer with the beverage base must be taken out of the warm liquid, so that the beverage base does not release further flavorings and active ingredients into the liquid. However, this is usually cumbersome, and the user relies on using an additional container or plate on which the filter or strainer is placed after use.
The present disclosure is based on the object to provide a filter system, which eliminates the aforementioned problems and allows a simple and user-friendly, individual adjustment of the steep time of the beverage base within a liquid.
A filter system for preparing beverages based on a beverage base, such as for example coffee powder, soup powder, or tea comprises a filter or strainer provided for use in a container and by which the beverage base is introduced into the heated liquid of a first liquid-receiving compartment which is provided in the container and in which the filtered beverage base develops and releases its ingredients to the liquid.
In the following, filter or strainer is to also be understood as bag-like filter devices such as tea bags and similar type containers for releasing a beverage base into a liquid, wherein the separation depending on needs the filter or the strainer may have a finer or coarser mesh, wire mesh, perforated plate or the like.
A device is provided which can be inserted into the container for forming a second liquid-receiving compartment, wherein the device comprises at least one flow-through opening, which can be closed, for liquid enriched with ingredients so that the beverage base in the second liquid compartment formed by the device cannot develop further.
By the disclosed filter system, it is now possible to individually adjust the steeping process by inserting the insertable device into the container in a simple and user-friendly manner. During the insertion process, the liquid flows from the first liquid-receiving compartment into the second liquid-receiving compartment in which no beverage base is left. After preferably complete absorption of the liquid in the second liquid-receiving compartment, the second liquid-receiving compartment or the device is closed at the at least one flow-through opening.
In a particularly advantageous embodiment, the filter is a filter/straining container which can be inserted into the container, wherein the filter/strainer container is advantageously adapted in shape and size approximately to the container.
In an advantageous embodiment of the invention, the device is a container-shaped receptacle which can be inserted into the container or the filter/strainer container and has at least one flow-through opening.
In a further embodiment, the device is a plate or dish-shaped valve which can be inserted into the container or the filter/strainer container and which has at least one flow-through opening, wherein the valve seals form-fitting and tight against the inner wall of the container.
On the container or on the filter/strainer container a closing means is preferably provided which closes the at least one flow-through opening in a positive locking and/or friction locking manner by introducing the device into the container.
Other objects, features, advantages and applications of the filter system of the invention will become apparent from the following description of an embodiment with reference to the drawings.
As illustrated in
In the embodiment of the invention shown in
In both illustrated embodiments a closing means 22 is preferably provided on the container 2 or on the filter/strainer container 12 which closes the at least one flow-through opening 110 by positive locking and/or friction locking by introducing the device 11 into the container 2 or the filter/strainer container 12, wherein the closing means 22 is here formed as a plug which upwardly projects into the flow-through opening 110 from the container bottom 23 or from the filter/strainer container bottom 120.
Furthermore, the valve 112 preferably comprises at least one holding member 1120 which upwardly projects above the container edge 24 after insertion into the container 2, and which is very particularly preferably designed to be flexible.
The filter system 1 according to the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of design variations are conceivable, which make use of the solution shown even with fundamentally different type of execution.
