Description
Description Filter-paper insert for a filter holder The present invention concerns a filter-paper insert for a filter holder for producing brewed drinks such as coffee or tea.
Filter-paper inserts of the generic type are known in all sorts of implementation forms.
The shape of such filter-paper inserts is essentially dependent on the purpose of usage at the time, i.e., a filter-paper insert in each case fits the form of the filter holder being used at the time.
The best known filter-paper inserts are formed like bags and exhibit approximately a truncated conical outline. Here two layers of filter paper lying one on top of the other are connected with each another via a common folded edge and are bonded to each other, preferably by means of pressed seams, in the region of a bottom edge and one of the other side edges lying opposite the folded edge.
Filter-paper inserts without seam locations are known, for example, sheet-shaped filter-paper inserts for correspondingly shaped filter holders, e.g., for so-called round filters.
Furthermore, filter-paper inserts in multiply folded forms are known in which a holder-like form can be made by appropriate folding from a single-layer blank, the form corre-sponding to the filter holder that is being used at the time.

The shape of such filter-paper inserts is essentially dependent on the purpose of usage at the time, i.e., a filter-paper insert in each case fits the form of the filter holder being used at the time.
The best known filter-paper inserts are formed like bags and exhibit approximately a truncated conical outline. Here two layers of filter paper lying one on top of the other are connected with each another via a common folded edge and are bonded to each other, preferably by means of pressed seams, in the region of a bottom edge and one of the other side edges lying opposite the folded edge.
Filter-paper inserts without seam locations are known, for example, sheet-shaped filter-paper inserts for correspondingly shaped filter holders, e.g., for so-called round filters.
Furthermore, filter-paper inserts in multiply folded forms are known in which a holder-like form can be made by appropriate folding from a single-layer blank, the form corre-sponding to the filter holder that is being used at the time.
Up to now filter-paper inserts of the generic type have exclusively the task of holding ground coffee or tea, from which, through brewing with hot water, a corresponding brewed drink is then produced in the filtering process.
The fundamental task for the present invention is to create a filter-paper insert of the generic type, by aid of which insert a brewed drink, for example, coffee or tea, can be additionally flavored in a simple way.
The task is solved thus according to the invention, in that the filter-paper insert is pro-vided with at least one hollow chamber closed on all sides and filled with a flavor car-ner.
With such a filter-paper insert a flavored brewed drink, for example, coffee or tea, can be produced in the simplest way.
Corresponding to the particular taste, a filter-paper insert according to the invention can be imparted with the most varied flavors. Many coffee drinkers love, for example, to add amaretto, egg liquor, rum, cognac or the like to the coffee, in order to achieve a certain taste effect. Appropriate flavoring materials can be added to such a filter paper according to the invention without anything else being required, so that the appropriate flavor is already imparted after the production of the brewed drink itself.
In many cases, the advantage is here achieved that the drink is completely alcohol free, as opposed to such brewed drinks into which true alcoholic drinks are mixed.
According to a further development of the invention it is planned that the hollow cham-ber is filled with a flavor carrier in the form of a dry water-soluble powder.
Another possibility consists in using a flavor carrier in the form of a dry power pressed into tablet form.
Likewise it is conceivable to use a liquid flavor carrier that itself is placed in a water-soluble bag and together with the bag is placed in a hollow chamber of a filter-paper insert according to the invention. In this case one must obviously take care that the en-velope of the flavor carrier consists of a food-safe material.
Further features of the invention are the object of other dependent claims.
Represented in the attached drawings are implementation examples, which are de-scribed in more detail in the following.
They show:
Fig. 1 . a view of a flat-lying filter-paper insert according to the present invention Fig. 2. a partial section along line II-II in Fig. 1 Fig. 3. views of flat-lying filter-paper inserts according to other implementation examples of the invention In Fig. 1 is shown a filter-paper insert 1 for a filter holder for production of brewed drinks such as coffee or tea, which filter-paper insert in a flat-lying condition displays approximately a truncated conical basic surface and in known ways displays a folded edge 2, a bottom seam 3 and a side seam 4.
The upper edge 5 of the filter-paper insert 1 opposite the bottom seam 3 is the filler opening that makes possible the filling of ground coffee or tea into the filter-paper insert 1 after insertion of the filter-paper insert 1 into a correspondingly truncated conical filter holder.
An additional filter-paper layer 6 is placed on the visible surface of the filter-paper insert 1 according to Fig. 1 . This additional filter-paper layer 6 is bonded by means of pressed seams with the filter-paper insert 1, both in the region of the bottom seam 3 as well as in the region of the side seam 4, and also in the region of the side edge 2, whereby these pressed seams are produced in one pass along with the production of the already necessary bottom seam 3 and the likewise necessary side seam 4.
Additional pressed seams 7 are made at a certain distance from the floor seam 3 and the side seam 4, whereby these pressed seams 7 merely bond the additional paper layer 6 with the directly opposite side wall 8 of the filter-paper insert 1 . This is very clear from Fig. 2.
Through these additional pressed seams 7 a canal-like hollow chamber 9 is defined, which chamber in the region of the upper edge 5 is closed off by means of an additional pressed seam 10. Into this hollow chamber 9 a flavor carrier 1 1 is filled and that pref-erably in the form of a dry water-soluble powder. During the production of the brewed drink this flavor carrier 1 1 is most extensively dissolved by the hot water and it gives its flavor to the produced brewed drink, e.g., coffee or tea. Thus, in all, a coffee or a tea with an additional flavor effect is achieved.
With the implementation examples according to Fig. 1 and 2 the canal-like hollow chamber 9 for taking up the flavor carrier 1 1 is formed through an additional filter-paper layer 6 and through appropriate additional pressed seams 7 and 10.
With the implementation example according to Figs. 3 and 4 an appropriate hollow chamber 9 is created by the direct joining of opposite filter-paper layers of the filter-paper insert 1 through additional pressed seams 7 and 10. In the implementation form according to Fig. 3 these additional seams 7, for example, run parallel to the lateral fold edges 2 and the hollow chamber 9 formed in this way is closed off by another planned pressed seam 10 in the region of the upper edge 5 of the filter-paper insert 1 . Here also the hollow chamber 9 accepts a flavor carrier.
With the implementation example according to Fig. 4 the additional pressed seam 7 runs approximately parallel to the bottom seam 3, so that in this case a hollow chamber 9 is created in the bottom region of the filter-paper insert 1 for taking up a flavor carrier.
Fig. 5 shows the possibility of creating a hollow chamber 9 for accepting a flavor carrier that places, for example, a rectangularly bounded additional filter-paper layer 6a onto a partial region of the filter-paper insert 1 and by means of pressed seams 7 is bonded to the directly opposite side wall of the filter-paper insert 1 .
The represented implementation examples are only supposed to make clear in a repre-sentative way that multiple possibilities exist for providing a filter-paper insert 1 with a hollow chamber 9 for taking up a flavor carrier.
At this point it should also be expressly pointed out that even with single-layer filter-paper inserts, e.g., so-called round filters, additional hollow chambers can be created for taking up flavor carriers by placing on an additional filter-paper layer that is bonded to the actual round filter sheet by means of pressed seams or other bonding techniques.
Whether a powder-form, tablet-form or liquid flavor carrier is placed into the hollow chamber 9 prepared at the time is of secondary importance for the intended flavor re-sults. It can certainly be advantageous, depending on the properties of the flavor carrier used, to decide on one or the other of the given possibilities.
If need be, a filter-paper insert can be provided with several hollow chambers 9 for tak-ing up flavor carriers.

Here also the hollow chamber 9 accepts a flavor carrier.
With the implementation example according to Fig. 4 the additional pressed seam 7 runs approximately parallel to the bottom seam 3, so that in this case a hollow chamber 9 is created in the bottom region of the filter-paper insert 1 for taking up a flavor carrier.
Fig. 5 shows the possibility of creating a hollow chamber 9 for accepting a flavor carrier that places, for example, a rectangularly bounded additional filter-paper layer 6a onto a partial region of the filter-paper insert 1 and by means of pressed seams 7 is bonded to the directly opposite side wall of the filter-paper insert 1 .
