摘要： A filter device for coffee or the like which includes a container body consisting of an open frame and a blind-end frame including an annular bottom member, and a filter chamber for enclosing substance to be extracted and received in the annular bottom member via a filter, wherein the blind-end frame is adapted to be folded inside the open frame together with the filter chamber. The open frame is formed of sheet material having predetermined rigidity, such as thick paper, non-woven fabric, etc., while the blind-end frame is formed of deformable sheet material provided with shape retaining characteristic having predetermined rigidity and flexibility such as thin paper, non-woven fabric, etc. These open frame and the blind-end frame are connected so as to be folded. When the filter device is not in use, the blind-end frame is folded and pushed into the open frame while turned back to be stored inside the open frame together with the filter device. Thus, the filter device can be stored or transported in a compact state. For use, the blind-end frame may be expanded while pulling out the filter chamber, restored to the container body of a cup-like shape, and mounted on a coffee cup or the like to be poured with hot water.

摘要： 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.
