To squeeze the paper filter bag and so in the The preparation of a cup of coffee or coffee beans to accommodate the lower part of the plastic ring 1, 30 enabling such a preparation in the that the paper filter bag is flush with the lower frame of a large company, for example, the conclusion of the plastic ring 1 completes. By ensuring that people are sent to certain locations Folding can be proceeded in this way. Automatic dispensers can be set up from which the fact that the coffee portion packs according to the invention on a special lower end part can be dispensed with entirely, since the inserted paper 35 can be removed. Next to these machines I have fulfilled this purpose. Of course there can be hot water heaters that are on it is possible, especially about when the push of a button starts a predetermined amount of water from coffee packets are capable of long-term storage, or have seen filter coffee these are attached to their upper and lower abmachines, as they have been in use for years End surfaces are covered with a peelable film.

th filter is used. In which the F i g. 10 of these claims: Auslegeschrift corresponding Ausführungsbeispiei, the side wall is designed in the form of a bellows. 1. Filter pack for coffee, in particular for formed, which has the advantage that the outer dimensions of the cup portions for quick filtering, consisting of 5 solutions of the hollow body within certain limits, the plastic ring containing the coffee is adapted to the inner dimensions of the filter container closed with a plastic lid, the can. In this case, too, it is, however, characterized in that the ring disc, which is only located opposite the flat plastic cover (6) at the bottom of the hollow body, is a filter paper. Here, too, the opening of the plastic ring (1) results from a disadvantage, with the io, that rapid filtering is not possible. The object of the invention is to create a filter bag (5) which can be folded out from the plastic filter pack for the upper edge of the plastic filter bag (5) at half the shortest possible time , the lower part of the plastic ring arranged outer shape is designed so that it is attached as a small ring cam (3). t ₅ and handy coffee portion pack also from one 2.

The coffee brewed in this way Especially for use in normal coffee, it can quickly have a sufficiently large filter surface filter is suitable. This consists of a conical filter. So there is a comparative Bowl, the bottom of which has openings or with only a short waiting time until the fresh one is consumed Filter paper is covered. At a distance from the 40 brewed drink. The invention is therefore suitable Another floor is arranged on this floor. Especially for the supply of workforces in between there is a measured amount of coffee in large establishments for quick-filter coffee grounds. The side walls of the bowl are so far tion, with the output via vending machines extended upwards that a cup-like shape can be made. arises. This pack is known per se.
