A filter device for coffee or the like which includes an open frame 2 formed of sheet material having predetermined rigidity, such as thick paper, and which is smaller in diameter than a blind-end frame 3. Both the frames are connected by a tubular body part 5 formed of deformable sheet material provided with shape retaining ability having predetermined rigidity and flexibility such as thin paper, non-woven fabric, etc. to compose a cup-like container body 1 having a wider bottom in a shape of substantially truncated cone. The filter device can be placed on a coffee cup for use. When the filter device is not in use, the open frame 2 is folded and pushed into the blind-end frame 3 by means of flexibility of the body part 5 and contracted. For use, the open frame 2 is pulled up to expand the body part 5, and the container body is restored into the cup-like shape and prepared to be poured with hot water.
