<p>A drip bag assembly (1) comprises a filter bag (3) containing a material to be extracted therein, having upper (3b), lower (3b) and two-side corners (3e,3d) with no openings and having a cut-off line (3d) made along upper corner and a holder (5). The holder (5) includes two arms (9) and a turn-in area (13). The arm (9) is made of an upper portion of the paper material body, has a shoulder on the fold over line side and a free end on the opposite side. The turn-in area (13) is defined by a cut line (10) extending across the fold over line (6) and two ridge-fold lines (11), respectively, extending from the ends of the cut line (10) downwardly. Upon folded inwardly, the area (13) will serve as a brace generating a force for keeping the holder halves (7) separated. Thus, the holder halves (7) bend outwardly in opposite direction, and the opening of the filter bag (3) can surely be kept opened. Further, there is formed a protruding portion (15). The holder can be supported on the cup by three points provided by the arms (9) and the protruding portion (15). <IMAGE></p> |
