PURPOSE:To reduce extra consumption of resources and to help resolution of dust pollution by manufacturing a cup part and an extraction part of a casset coffee in such a way as they can be assembled and making a cup receiving part which works as a hanging part to a coffee cup and the extraction part of paper. CONSTITUTION:In order to form an extraction part of a casset coffee, a cup receiving base plate 10 made of waterproof, heatproof, flexible board paper is cut in a circle. A through hole 101 is pierced in the center of the base plate 10. Further, one-dot-chain-lined and large and small circular channels 102, 103 and 1031 are formed concentric with the through hole 101. In addition, cuttings 104, 104... are made by a cutter properly forward and backward from the large channel 103 across the through hole 101. The extraction part 20 consists of a lower filter paper 201 and an upper filter paper 202, and a lower part of the lower filter paper 201 is formed in an upside-down dome in the cross section just like a pot bottom shape. By this, coffee liquid gathers in the central part of the filter paper, whereby a small amount of coffee powder can be extracted efficiently. |
