Japanese Patent JP3045519
Kind Code:
B2
Abstract:
A cassette (14) for producing coffee by the cup or pot and for use with a liquid receptacle (12) having an internal locking flange (26). The cassette comprises a ring (36) defining an interior and forming a bottom annular groove (32) to receive the locking flange (26) of the liquid receptacle (12) and thereby to hold the cassette in place therein. The cassette further includes a plurality of ribs (40) connected to and extending across the ring and separating the interior thereof into a multitude of sections, and coffee particles (24) disposed in said sections. A bottom filter (44) and a top filter (42) are secured to the ring and extend across the bottom and top, respectively, of the interior of the ring to hold the flavoring particles therein. Preferably, the cassette is packaged in a sealed vacuum pack; and as it is so packaged, the mass of particles in each section of the cassette is reshaped slightly and formed into a firm conglomerate, which facilitates the subsequent flow of hot water through the cassette.
