PURPOSE:To secure shape keeping performance and to prevent spilling, etc., of a matter to be extracted such as coffee, etc., by adhering four corners of the bottom of a support board and forming inward folding lines from the edge of each adhered part toward the vicinity of a small hole at the central folding line. CONSTITUTION:This extraction utensil for coffee, etc., comprises a support plate 10 and a filter paper 20. A plurality of leg part 13 and bottom part 13 are continuously set via a folding line (a), and a small hole 16 and a folding line (b) are formed at the center of the bottom part 11, and four folding lines are formed radially from the vicinity of the small hole 16. A filter paper 20 is adhered on the bottom 11 and they are folded to form a vessel part. The adhesion is performed by placing one upon another at the four corners of the bottom and folding via folding line (c). Two side parts 12 are formed by folding and standing the folding line (c) and a designated side face by inward folding the central folding line. An inward folding line (d) is folded to form the vessel part. |
