    Abstract: The invention is directed to a filter bag (10) consisting of filter paper for producing brewed beverages such as coffee or tea, comprising a holding space (17) for holding a substance, such as coffee grinds or tea leaves, and being made up of a folded filter sheet blank (1) having two filter sheet sides (11, 12). The filter sheet sides (11, 12) are of essentially identical shape and size, having one bottom edge (13) and two side edges (22, 24 and 23, 25). The side edges (22, 24; 23, 25) diverge upwards and include at their upper ends top edges (14, 15) for forming a filling opening (30), with the bottom edge (13) and the side edges (22, 24; 23, 25) of the two filter sheet sides (11, 12) being either connected with each other in a positive engagement relationship, in which case they form bottom and/or side strips (37 and/or 28, 29) in this area, or connected with each other in one integral piece in these areas, in order to form a filter bag (10).
