<P>PROBLEM TO BE SOLVED: To provide an extractor for a hand drip capable of easily extracting a component of coffee bean powder, extremely simple in a structure, superior in easiness-to-use, easy in cleaning and the replacement, and inexpensively manufacturable, by using filter paper and a metallic coffee extractor. <P>SOLUTION: Clearance between a projecting rib and a cutout becomes a liquid introducing passage by arranging the notch in an inner bottom part of a filtering part 16, and slowly and intermittently drips a filtering liquid 29 over a wide range on the coffee bean powder 28. Fine powder 30 mixed in an extracting liquid caused when using a metallic filter, is also removed by precipitating by arranging precipitation groove reservoirs 24 and 25. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
